From abad398337f038f5822e53c55eff5b0820ef7efe Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Wed, 8 Apr 2015 18:26:12 +0300 Subject: [PATCH 0001/1302] iio: pressure: bmp280: fix temp compensation Temperature reads on bmp280 device always return 0, due to a missing step in the compensation formula (data->tfine is never initialized). Initialize data->tfine value so we get correct temperature and pressure values.

This patch adds missing channel info masks for all ADC channels. Otherwise, iio_read_channel_raw() would return -EINVAL when called by consumer drivers. Note that the change of _processed to _raw actually fixes an ABI abuse in the original driver where it was used to avoid some special handling rather than because it was correct.

McKenney" Date: Tue, 14 Apr 2015 19:33:59 -0700 Subject: [PATCH 0005/1302] rcu: Control grace-period delays directly from value In a misguided attempt to avoid an #ifdef, the use of the gp_init_delay module parameter was conditioned on the corresponding RCU_TORTURE_TEST_SLOW_INIT Kconfig variable, using IS_ENABLED() at the point of use in the code. This meant that the compiler always saw the delay, which meant that RCU_TORTURE_TEST_SLOW_INIT_DELAY had to be unconditionally defined. This in turn caused "make oldconfig" to ask pointless questions about the value of RCU_TORTURE_TEST_SLOW_INIT_DELAY in cases where it was not even used. This commit avoids these pointless questions by defining gp_init_delay under #ifdef. In one branch, gp_init_delay is initialized to RCU_TORTURE_TEST_SLOW_INIT_DELAY and is also a module parameter (thus allowing boot-time modification), and in the other branch gp_init_delay is a const variable initialized by default to zero. This approach also simplifies the code at the delay point by eliminating the IS_DEFINED(). Because gp_init_delay is constant zero in the no-delay case intended for production use, the "gp_init_delay > 0" check causes the delay to become dead code, as desired in this case. In addition, this commit replaces magic constant "10" with the preprocessor variable PER_RCU_NODE_PERIOD, which controls the number of grace periods that are allowed to elapse at full speed before a delay is inserted.

This patch adds setting the upper bits of the buffer address in ext_cmd_line_ptr. This case was likely never hit, as the allocation for this buffer is done at the lowest available address. Only x86_64 kernels have this problem, as the 1-1 mapping mandated by EFI ensures that all memory is 32 bit addressable on 32 bit platforms. The EFI stub does not support mixed mode, so the 32 bit kernel on 64 bit firmware case does not need to be handled.

The scan is run by a separate entity called auxiliary MAC (aka AUX MAC). This AUX MAC needs to get Tx power limitations that are not applied on a specific vif, but on the device as a whole. This can be implemented by using the minimum of all the values set by the user for all the MACs. But then we need to ignore the limitations that come from the AP or regulatory for a specific vif: a specific vif might have regulatory limitations because of the channel is works on. This limit is irrelevant for the AUX MAC. Use the new API from mac80211: the user_power_level in bss_conf to achieve this. Firmware -13.ucode has already moved to this API.

The simplest way of ensuring this is for the edge device to always impose the labels, and not allow forward labeled traffic from untrusted neighbours. This is achieved by allowing a per-device configuration of whether MPLS traffic input from that interface should be processed or not. To be secure by default, the default state is changed to MPLS being disabled on all interfaces unless explicitly enabled and no global option is provided to change the default. Whilst this differs from other protocols (e.g. IPv6), network operators are used to explicitly enabling MPLS forwarding on interfaces, and with the number of links to the MPLS core typically fairly low this doesn't present too much of a burden on operators.

The address of the parameter RAM is given by the boot loader and expected to be mapped via devm_ioremap_resource() In the current implementation, in function fsl_spi_cpm_get_pram() there is a confusion between the SPI_BASE register and the base of the SPI parameter RAM. Fortunatly, it is working properly with MPC866 and MPC885 because they do set SPI_BASE, but on MPC860 and other old MPC8xx that doesn't set SPI_BASE, pram_ofs is not properly set. Also, the parameter RAM is not properly mapped with devm_ioremap_resource() as it should but still gets accessible by chance through the full RAM which is mapped from somewhere else. This patch applies to the SPI driver the same principle as for the CPM UART: when the CPM is of type CPM1, we simply do an devm_ioremap_resource() of the area provided via the device tree.

So, in the ibmveth driver, the maximum allowed MTU is determined by the maximum allocated buffer size of 64k (corresponding to one page in the common case) minus the per-buffer overhead IBMVETH_BUFF_OH (which has value 22 for 14 bytes of ethernet header, plus 8 bytes for an opaque handle). This suggests a maximum allowable MTU of 65514 bytes, but in fact the driver only permits a maximum MTU of 65513. This is because there is a < instead of an <= in ibmveth_change_mtu(), which only permits an MTU which is strictly smaller than the buffer size, rather than allowing the buffer to be completely filled. This patch fixes the buglet. Signed-off-by: David Gibson Acked-by: Thomas Falcon Signed-off-by: David S.

Although the socket's namespace is forcedly changed to the new namespace later, the socket is still stored in the socket hash table of "init ns" namespace. When a client created in the new namespace connects its own topology server, the connection is failed as its server's socket could not be found from its own namespace's socket table. If __sock_create() instead of original sock_create_kern() is used to create the server's socket through specifying an expected namesapce, the socket will be inserted into the specified namespace's socket table, thereby avoiding to the topology server broken issue.

There are three places where +1 is used for this purpose - one in pos_ratio_polynom() and two in bdi_position_ratio(). The second one in bdi_position_ratio() actually triggered div-by-zero oops on a machine running a 3.10 kernel. The divisor is x_intercept - bdi_setpoint + 1 == span + 1 span is confirmed to be (u32)-1. It isn't clear how it ended up that but it could be from write bandwidth calculation underflow fixed by c72efb658f7c ("writeback: fix possible underflow in write bandwidth calculation"). At any rate, +1 isn't a proper protection against div-by-zero. This patch converts all +1 protections to |1. Note that bdi_update_dirty_ratelimit() was already using |1 before this patch.

Fix it, by calling perf_evlist__enable() in the 'trace' tool when forking and not targetting a workload started from trace v2: Test against !target__none(), as suggested by Namhyung Kim, that is what is used in perf_evsel__config() when deciding if the attr.enable_on_exec flag to be set. More work is needed to cover other cases such as opts->initial_delay.

Lets try a different strategy : In case of memory pressure, try to add the FIN flag to last packet in write queue, even if packet was already sent. TCP stack will be able to deliver this FIN after a timeout event. Note that this FIN being delivered by a retransmit, it also carries a Push flag given our current implementation. By checking sk_under_memory_pressure(), we anticipate that cooking many FIN packets might deplete tcp memory. In the case we could not allocate a packet, even with __GFP_WAIT allocation, then not sending a FIN seems quite reasonable if it allows to get rid of this socket, free memory, and not block the process from eventually doing other useful work.

In order to test the bug and verify the fix I set my rhashtable's max_size very low (4) in order to force getting hash collisions. At that point, rhashtable WARNed in rhashtable_insert_rehash() but didn't actually reject the hash table insertion. This caused it to lose insertions - my master list of stations would have 9 entries, but the rhashtable only had 5. This may warrant a deeper look, but that WARN_ON() just shouldn't happen. Fix this by not returning true from rht_grow_above_100() when the rhashtable's max_size has been reached - in this case the user is explicitly configuring it to be at most that big, so even if it's now above 100% it shouldn't attempt to resize.

Before commit fa76ce7328b2 ("inet: get rid of central tcp/dccp listener timer"), listener spinlock was held and race could not happen. To solve this bug, we change reqsk_queue_unlink() to not assume req must be found, and we return a status, to conditionally release a refcount on the request sock. This also means tcp_check_req() in non fastopen case might or not consume req refcount, so tcp_v6_hnd_req() & tcp_v4_hnd_req() have to properly handle this. (Same remark for dccp_check_req() and its callers) inet_csk_reqsk_queue_drop() is now too big to be inlined, as it is called 4 times in tcp and 3 times in dccp.

The device is shutdown properly for drivers that implement legacy ->set_mode() callback, as we call ->set_mode() for CLOCK_EVT_MODE_UNUSED as well. But for the new per-state callback interface, we skip shutting down the device, as we thought its an internal state change. That wasn't correct. The effect is that the device is left programmed in oneshot or periodic mode. Fall-back to 'case CLOCK_EVT_STATE_SHUTDOWN', to shutdown the device.

Until now this driver could only be used for half-duplex transfers, since it always expected an spi_transfer with non-null tx_buf to be only used for TX, and those with non-null rx_buf to be only used for RX. The fix consists in correcting the fsl_espi_transfer length by taking into consideration duplex spi_transfers, and not just by adding n_tx and n_rx. Furthermore, this correction has exposed an inconsistency in the protocol driver <-> controller driver interaction. The spi-fsl-espi driver artificially inserts TX bytes when message fragmentation is necessary (due to SPCOM_TRANLEN_MAX) instead of informing the protocol driver of the hardware limitation. This was tested with the m25p80 NOR flash protocol driver. Since fixing this issue may cause other client drivers to malfunction, it was left as is.

However this second iteration of the loop could cause a deadlock because it tries to lock some other extent tree node/leaf which another task already locked and it's blocked because it's waiting for a lock on some node/leaf that is in our path that was not released before. We could also deadlock when running the delayed references - as we could end up trying to lock the same nodes/leafs that we have in our local path (with a different lock type).

We need to fill inode when we found a node for it in delayed_nodes_tree. But we did not fill the ->last_trans currently, it will cause the test of xfstest/generic/311 fail. Scenario of the 311 is shown as below: Problem: (1). test_fd = open(fname, O_RDWR|O_DIRECT) (2). pwrite(test_fd, buf, 4096, 0) (3). close(test_fd) (4). drop_all_caches() <-------- "echo 3 > /proc/sys/vm/drop_caches" (5). test_fd = open(fname, O_RDWR|O_DIRECT) (6). fsync(test_fd); <-------- we did not get the correct log entry for the file Reason: When we re-open this file in (5), we would find a node in delayed_nodes_tree and fill the inode we are lookup with the information. But the ->last_trans is not filled, then the fsync() will check the ->last_trans and found it's 0 then say this inode is already in our tree which is commited, not recording the extents for it. Fix: This patch fill the ->last_trans properly and set the runtime_flags if needed in this situation. Then we can get the log entries we expected after (6) and generic/311 passed.

In a follow up patch, we might get rid of compares against nr_cpu_ids, if we init the tables with 0. This is silly to test for a very unlikely condition that exists only shortly after table initialization, as we got rid of rps_reset_sock_flow() and similar functions that were writing this RPS_NO_CPU magic value at flow dismantle : When table is old enough, it never contains this value anymore.

The default PM domain is still needed for: - platforms without genpd support, - the legacy (non-DT) case, where genpd may take over later, except for the C5 "always on" PM domain.

This isn't too critical, though, as the string is stopped at the succeeding longname string. This patch fixes such entries by dropping "SB" prefix (it's enough to fit within 32 bytes, so far). Meanwhile, it also changes strcpy() with strlcpy() to make sure that this kind of problem won't happen in future, too.

The host is buggy and doesn't do this, and the result is observable when one vcpu reads another vcpu's kvmclock data. There's no good way for a guest kernel to keep its vdso from reading a different vcpu's kvmclock data, but we don't need to care about changing VCPUs as long as we read a consistent data from kvmclock. (VCPU can change outside of this loop too, so it doesn't matter if we return a value not fit for this VCPU.) Based on a patch by Radim Krčmář.

The task migration notifier was originally introduced in order to support the pvclock vsyscall with non-synchronized TSC, but KVM only supports it with synchronized TSC. Hence, on KVM the race condition is only needed due to a bad implementation on the host side, and even then it's so rare that it's mostly theoretical. As far as KVM is concerned it's possible to fix the host, avoiding the additional complexity in the vDSO and the (re)introduction of the task migration notifier. Xen, on the other hand, hasn't yet implemented vsyscall support at all, so we do not care about its plans for non-synchronized TSC.

The small amount of shared code between them is factored out into an extra helper function. This makes the code a lot cleaner.

-- GitLab From 3809f00159d31a6c92b557e09c7ca8e22b62ae7c Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 13 Apr 2015 13:27:54 +0100 Subject: [PATCH 0169/1302] ASoC: wm_adsp: Improve variable naming We have wm_adsp_region, wm_adsp_alg_region, and wmfw_region, the variables for which are all frequently called region, this can get quite confusing when reviewing the code especially given some functions are quite long. Consistently use mem for wm_adsp_regions, alg_region for wm_adsp_alg_region and region for wmfw_region. Additionally, we use a mix of adsp and dsp for pointers to the wm_adsp structure standardise this on dsp. Finally, we use algs to refer to the number of algorithms quite frequently, change this to the more descriptive n_algs.

These functions don't handle the kcontrols at all they just shuttle data to and from the chip and all the call sites have a wm_coeff_ctl pointer available.

This patch updates the processing to handle this version of the file format. Note that whilst this version of the format adds support for specifying a name for the control through the firmware file this has not been used and to keep compatibility with existing deployments no changes to the firmware control naming are made by this patch.

However this does increase the parsing complexity slightly. This patch adds support for the revision of the file format. This patch also adds a new naming scheme for controls created from rev 2 firmware files. This version of the file format is commonly used to add multiple controls per algorithm per memory region and the old control naming scheme would cause multiple controls to have the same name in this case.. Note that the naming scheme for older firmware versions is left intact to ensure backwards compatibility.

This patch validates al.map before dereferencing, avoid the segfault.

Because of the peculiar way that md devices are created (automatically when the device node is opened), a new device can be created and registered immediately after the blk_unregister_region(disk_devt(disk), disk->minors); call in del_gendisk(). Therefore it is important that all visible artifacts of the previous device are removed before this call. In particular, the 'bdi'. Since: commit c4db59d31e39ea067c32163ac961e9c80198fd37 Author: Christoph Hellwig fs: don't reassign dirty inodes to default_backing_dev_info moved the device_unregister(bdi->dev); call from bdi_unregister() to bdi_destroy() it has been quite easy to lose a race and have a new (e.g.) "md127" be created after the blk_unregister_region() call and before bdi_destroy() is ultimately called by the final 'put_disk', which must come after del_gendisk(). The new device finds that the bdi name is already registered in sysfs and complains > [ 9627.630029] WARNING: CPU: 18 PID: 3330 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x5a/0x70() > [ 9627.630032] sysfs: cannot create duplicate filename '/devices/virtual/bdi/9:127' We can fix this by moving the bdi_destroy() call out of blk_release_queue() (which can happen very late when a refcount reaches zero) and into blk_cleanup_queue() - which happens exactly when the md device driver calls it. Then it is only necessary for md to call blk_cleanup_queue() before del_gendisk(). As loop.c devices are also created on demand by opening the device node, we make the same change there.

The target returns: VPD INQUIRY: Block limits page (SBC) Maximum compare and write length: 1 blocks Optimal transfer length granularity: 1 blocks Maximum transfer length: 4294967295 blocks Optimal transfer length: 4294967295 blocks Maximum prefetch, xdread, xdwrite transfer length: 0 blocks Maximum unmap LBA count: 8388607 Maximum unmap block descriptor count: 1 Optimal unmap granularity: 16383 Unmap granularity alignment valid: 0 Unmap granularity alignment: 0 Maximum write same length: 0xffffffff blocks Maximum atomic transfer length: 0 Atomic alignment: 0 Atomic transfer length granularity: 0 and it is *sometimes* able to handle at least one IO of size up to 8 MB. We have seen in traces where it will sometimes work, but other times it looks like it fails and it looks like it returns failures if we send multiple large IOs sometimes. Also it looks like it can return 2 different errors. It will sometimes send iscsi reject errors indicating out of resources or it will send invalid cdb illegal requests check conditions. And then when it sends iscsi rejects it does not seem to handle retries when there are command sequence holes, so I could not just add code to try and gracefully handle that error code. The problem is that we do not have a good contact for the company, so we are not able to determine under what conditions it returns which error and why it sometimes works. So, this patch just adds a new black list flag to set targets like this to the old max safe sectors of 1024. The max_hw_sectors changes added in 3.19 caused this regression, so I also ccing stable.

This was working before commit ad6ac452227b7cb93ac79beec092850d178740b1 ("add new formats support for marvell-ccic driver"). That commit broke the original format support and the OLPC XO-1 laptop showed wrong colors ever since (if you are crazy enough to attempt to run the latest kernel on it, like I did). The email addresses of the authors of that patch are no longer valid, so without a way to reach them and ask them about their test setup I am going with what I can test on the OLPC laptop. If this breaks something for someone on their non-OLPC setup, then contact the linux-media mailinglist. My suspicion however is that that commit went in untested.

The FLAG_NO_RESIDUE was initially added when the DMAengine framework had no support for describing the residue reporting capabilities of the controller. Support for this was added quite a while ago and recently the DMAengine framework started to complain if a driver does not describe its capabilities and a lot of patches have been merged that add support for this where it was missing. So it should be safe to assume that driver on actively used platforms properly implement the DMA capabilities API. This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio controller drivers to manually set the flag. If a DMA driver against expectations does not support reporting its capabilities for now the generic DMAengine PCM driver will now emit a warning and simply assume that residue reporting is not supported. In the future this might be changed to aborting with an error.

Since the port lock is released before the packet is queued, the order in which the URBs are submitted is not guaranteed. E.g. sending thread completion (interrupt) gs_write() LOCK gs_write_complete() LOCK (wait) gs_start_tx() req1 = list_entry(pool->next) UNLOCK LOCK (acquired) gs_start_tx() req2 = list_entry(pool->next) UNLOCK usb_ep_queue(req2) usb_ep_queue(req1) I.e., req2 is submitted before req1 but it contains the data that comes after req1. To reproduce, use SMP with sending thread and completion pinned to different CPUs, or use PREEMPT_RT, and add the following delay just before the call to usb_ep_queue(): if (port->write_started > 0 && !list_empty(pool)) udelay(1000); To work around this problem, make sure that only one thread is running through the gs_start_tx() loop with an extra flag write_busy. Since gs_start_tx() is always called with the port lock held, no further synchronisation is needed. The original caller will continue through the loop when the request was successfully submitted.

It provides its own 'tps65010_set_vbus_draw' wrapper in case that driver is not enabled through Kconfig, but fails to handle the case where isp1301-omap is built-in but TPS65010 is a loadable module, which currently results in a link error: drivers/built-in.o: In function `isp1301_set_power': :(.text+0x14e188): undefined reference to `tps65010_set_vbus_draw' This is a workaround to use the same trick as before also when tps65010 is a module. Doing a proper fix would require much larger changes to the driver that is not really worth it when the usb-phy drivers are going to eventually get replaced with generic-phy drivers.

Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

This patch introduces a new helper function snd_soc_codec_get_dapm() which should be used for getting the DAPM context for a CODEC rather then directly accessing the dapm field. Once there are no more direct users of the dapm field left it is possible to transparently switch all drivers to the component DAPM context by updating snd_soc_codec_get_dapm() function.

The DAPM state itself is managed by the DAPM core though and the core has certain expectations on how and when the bias_level field should be updated. If drivers don't adhere to these undefined behavior can occur. This patch adds a few helper functions for manipulating the DAPM context state, each function with a description on when it should be used and what its effects are. This will also help us to move more of the bias_level management from drivers to the DAPM core. For convenience also add snd_soc_codec_* wrappers around these helpers.

Phil and I found out a problem with commit: 7e860a6e7aa6 ("cdc-acm: add sanity checks") It added some sanity checks to ignore potential garbage in CDC headers but also introduced a potential infinite loop. This can happen at the first loop iteration (elength = 0 in that case) if the description isn't a DT_CS_INTERFACE or later if 'buffer[0]' is zero. It should also be noted that the wrong length was being added to 'buffer' in case 'buffer[1]' was not a DT_CS_INTERFACE descriptor, since elength was assigned after that check in the loop. A specially crafted USB device could be used to trigger this infinite loop.

The first one is run when the driver loads and it returns calibrations results as well as the NVM. The second one implements the WiFi protocol. If the wlan interface is not brought up, the device is put to low power state: no firmware will be running. When the interface is brought up, we would run the OPER firmware only and reuse the results of the run of the INIT firmware when the driver was loaded. This is changing with this patch. We now run the INIT firmware every time mac80211 calls start(). The penalty for that is minimal since the INIT firwmare run fast. I now also avoid to power down the device between the INIT and OPER firmware on certains buses. The motivation for this change is that there are components on the device (MFUART) that are triggered by the INIT firmware and need the device to be powered up in order to keep running. Powering the device down between the INIT and OPER firmware would stop these components and prevent them from running again since they are triggered by the INIT firmware only. The new flow allows this and also allows to trigger these components again when the interface is brought up after it has been brought down.

When function s3c64xx_serial_startup() was started while serial console has been working, it caused lose of characters written to TX FIFO. This effect was particularly observable with systemd, which closes serial port every time when it's not currently needed, hence function s3c64xx_serial_startup() is called quite often there. To fix this problem we avoid resetting TX FIFO if port is used as serial console. Example of broken console log: [ 1086.7 Expecting device dev-ttySAC1.device... [ 1086.[ OK ] Reached target Paths.

But two chips can be combined to act as a single 16 port chip. Therefor one chip is configured as master the second as slave by connecting the mode pin to VCC (master) or GND (slave). Then the master chip is reporting a different device-id depending on whether a slave is detected or not. The UARTs 8-15 are addressed from 0x2000-0x3fff. So the offset of 0x400 from UART to UART can be used to address all 16 ports as before.

It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

Fix that by moving the invocations of tick_broadcast_enter() and tick_broadcast_exit() down into cpuidle_enter_state() where interrupts are still disabled when tick_broadcast_exit() is called. Also ensure that interrupts will be disabled before running tick_broadcast_exit() even if they have been enabled by the idle state's ->enter callback. Trigger a WARN_ON_ONCE() in that case, as we generally don't want that to happen for states with CPUIDLE_FLAG_TIMER_STOP set.

With this change when a Xen guest tries to resume, it won't be calling its set_mode op which needs to be done on each VCPU in order to make the hypervisor aware that we are in oneshot mode. This happens because clockevents_tick_resume() (which is an intermediate step of resuming ticks on a processor) doesn't call clockevents_set_state() anymore and because during suspend clockevent devices on all VCPUs (except for the one doing the suspend) are left in ONESHOT state. As result, during resume the clockevents state machine will assume that device is already where it should be and doesn't need to be updated. To avoid this problem we should suspend ticks on all VCPUs during suspend.

Introduce netif-msg to netvsc to control debug logging output and keep msg_enable in netvsc_device_context so that it is kept persistently. 2. Only call dump_rndis_message() when NETIF_MSG_RX_ERR or above is specified in netvsc module debug param. In non-debug mode, in current code, dump_rndis_message() will not dump anything but it still initialize some local variables and process the switch logic which is unnecessary, especially in high network throughput situation.

This entails two problems: - With an unlucky combination of arriving packets the algorithm may go into a lockstep with the out-of-sequence handling function, where the synch mechanism is adding a packet to the deferred queue, while the out-of-sequence handling is retrieving it again, thus ending up in a loop inside the node_lock scope. - Even if this is avoided, the link will very often send out unnecessary protocol messages, in the worst case leading to redundant retransmissions.

The stale sysfs entries prevented the gpio numbers from being exported when the gpio range was later reused (e.g. at device reconnect). This also fixes the related module-reference leak. Note that kernfs makes sure that any on-going sysfs operations finish before the class devices are unregistered and that further accesses fail. The chip exported flag is used to prevent gpiod exports during removal. This also makes it harder to trigger, but does not fix, the related race between gpiochip_remove and export_store, which is really a race with gpiod_request that needs to be addressed separately. Also note that this would prevent the crashes (e.g. NULL-dereferences) at reconnect that affects pre-3.18 kernels, as well as use-after-free on operations on open attribute files on pre-3.14 kernels (prior to kernfs).

Although the principle of this change is good, the implementation has a few issues. Firstly we can sometimes fail to abort a syscall because r12 may have been clobbered by C code if we went down the virtual CPU accounting path, or if syscall tracing was enabled. Secondly we have decided that it is safer to abort the syscall even earlier in the syscall entry path, so that we avoid the syscall tracing path when we are transactional. So that we have time to thoroughly test those changes we have decided to revert this for this merge window and will merge the fixed version in the next window. NB. Rather than reverting the selftest we just drop tm-syscall from TEST_PROGS so that it's not run by default.

Otherwise, reloading a blk-mq request-based DM table (either manually or via multipathd) resulted in errors, see: https://www.redhat.com/archives/dm-devel/2015-April/msg00132.html Fix is to only initialize the request_queue on the initial table load (when the mapped_device type is assigned). This is better than having dm_init_request_based_blk_mq_queue() return early if the queue was already initialized because it elevates the constraint to a more meaningful location in DM core. As such the pre-existing early return in dm_init_request_based_queue() can now be removed.

It was an oversight to discontinue that check for 1 of the 2 use-cases for free_rq_clone(): 1) free_rq_clone() called when an unmapped original request is requeued 2) free_rq_clone() called in the request-based IO completion path The clone->q check made sense for case #1 but not for #2. However, we cannot just reinstate the check as it'd mask a serious bug in the IO completion case #2 -- no in-flight request should have an uninitialized request_queue (basic block layer refcounting _should_ ensure this). The NULL pointer seen for case #1 is detailed here: https://www.redhat.com/archives/dm-devel/2015-April/msg00160.html Fix this free_rq_clone() NULL pointer by simply checking if the mapped_device's type is DM_TYPE_MQ_REQUEST_BASED (clone's queue is blk-mq) rather than checking clone->q->mq_ops. This avoids the need to dereference clone->q, but a WARN_ON_ONCE is added to let us know if an uninitialized clone request is being completed.

The ACPI specification defines a bit (Producer/Consumer) to tell whether the resource is consumed by the host bridge itself, but firmware hasn't used that bit consistently, so we can't rely on it. Before commit 593669c2ac0f ("x86/PCI/ACPI: Use common ACPI resource interfaces to simplify implementation"), arch/x86/pci/acpi.c ignored all IO port resources defined by acpi_resource_io and acpi_resource_fixed_io to filter out IO ports consumed by the host bridge itself. Commit 593669c2ac0f ("x86/PCI/ACPI: Use common ACPI resource interfaces to simplify implementation") started accepting all IO port and MMIO resources, which caused a regression that IO port resources consumed by the host bridge itself became available to its child devices. Then commit 63f1789ec716 ("x86/PCI/ACPI: Ignore resources consumed by host bridge itself") ignored resources consumed by the host bridge itself by checking the IORESOURCE_WINDOW flag, which accidently removed MMIO resources defined by acpi_resource_memory24, acpi_resource_memory32 and acpi_resource_fixed_memory32. On x86 and IA64 platforms, all IO port and MMIO resources are assumed to be available to child bus/devices except one special case: IO port [0xCF8-0xCFF] is consumed by the host bridge itself to access PCI configuration space. So explicitly filter out PCI CFG IO ports[0xCF8-0xCFF]. This solution will also ease the way to consolidate ACPI PCI host bridge common code from x86, ia64 and ARM64.

At some point, when all RX buffers deplete, driver may fall into a sleep, and not recover when memory for new RX buffers is once again availible. This is because hardware does not have valid descriptors, so no interrupt will be generated for the driver to return to work in napi context. Fix it by schedule the napi poll function from stats_task delayed workqueue, as long as the allocations fail. Signed-off-by: Ido Shamay Signed-off-by: Amir Vadai Signed-off-by: David S.

When gpio-pxa was moved to drivers/pxa, it became a driver, and its initialization and probing happened at postcore initcall. The lubbock code used to install the chained lubbock interrupt handler at init_irq() time. The consequence of the gpio-pxa change is that the installed chained irq handler lubbock_irq_handler() was overwritten in pxa_gpio_probe(_dt)(), removing : - the handler - the falling edge detection setting of GPIO0, which revealed the interrupt request from the lubbock IO board. As a fix, move the gpio0 chained handler setup to a place where we have the guarantee that pxa_gpio_probe() was called before, so that lubbock handler becomes the true IRQ chained handler of GPIO0, demuxing the lubbock IO board interrupts. This patch moves all that handling to a mfd driver. It's only purpose for the time being is the interrupt handling, but in the future it should encompass all the motherboard CPLDs handling : - leds - switches - hexleds The same logic applies to mainstone board.

However, the (software) frozen state EEH_PE_ISOLATED is missed. When users get 0xFF from PCI config or MMIO read, EEH_PE_ISOLATED is set in PE state retrival backend.

However, it's wrong for PowerNV platform because the PE# isn't determined until the resources (IO and MMIO) are assigned to PE in hotplug case.

If state loss has not occurred, control returns via the power7_wakeup_noloss() path which does not restore those condition registers, leaving them corrupted. Fix this by restoring the condition registers in the power7_wakeup_noloss() case. This is apparent when running a KVM guest on hardware that does not support winkle or sleep and the guest makes use of secondary threads. In practice this means Power7 machines, though some early unreleased Power8 machines may also be susceptible. The secondary CPUs are taken off line before the guest is started and they call pnv_smp_cpu_kill_self(). This checks support for sleep states (in this case there is no support) and power7_nap() is called. When the CPU is woken, power7_nap() returns and because the CPU is still off line, the main while loop executes again. The sleep states support test is executed again, but because the tested values cannot have changed, the compiler has optimized the test away and instead we rely on the result of the first test, which has been left in cr3 and/or cr4. With the result overwritten, the wrong branch is taken and power7_winkle() is called on a CPU that does not support it, leading to it stalling.

When writing support for these last SoCs, there was no official value for the PLL. Now that we have it, this patch fixes it in the device tree. This value is currently only used by the NAND driver for the setting the NAND timing.

By default, we pad the filenames to the next 4 byte boundaries. This costs nothing, since the directory entries are aligned to 4 byte boundaries anyway. Filenames can also be padded to 8, 16, or 32 bytes, which will consume more directory space.

When interrupted, the signal remains pending resulting in subsequent timeouts occurring instantly. This makes the loop spin at a much higher rate than intended. Instead of making this completely non-interruptible, we can change this into a sort of interruptible-once behavior and use the "once" to log debug information. The driver API doesn't allow us to abort and return an error code.

Only support the latter for now. For full passthrough, we will need to support a second se_subsystem_api template, due to configfs attributes being different between the two modes. Thus pass_level is extraneous, and we can remove it. The ABI break for TCMU v2 is already applied for this release, so it's best to do this now to avoid another ABI break in the future.

The problem is that when we insert delayed extent into extent status tree the only way to get rid of it is when we write out delayed buffer. However there is a limitation in the extent status tree implementation so that when inserting unwritten extent should there be even a single delayed block the whole unwritten extent would be marked as delayed. At this point, there is no way to get rid of the delayed extents, because there are no delayed buffers to write out. So when a we write into said unwritten extent we will convert it to written, but it still remains delayed. When we try to write into that block later ext4_da_map_blocks() will set the buffer new and delayed and map it to invalid block which causes the rest of the block to be zeroed loosing already written data. For now we can fix this by simply not allowing to set delayed status on written extent in the extent status tree. Also add WARN_ON() to make sure that we notice if this happens in the future. This problem can be easily reproduced by running the following xfs_io. xfs_io -f -c "pwrite -S 0xaa 4096 2048" \ -c "falloc 0 131072" \ -c "pwrite -S 0xbb 65536 2048" \ -c "fsync" /mnt/test/fff echo 3 > /proc/sys/vm/drop_caches xfs_io -c "pwrite -S 0xdd 67584 2048" /mnt/test/fff This can be theoretically also reproduced by at random by running fsx, but it's not very reliable, though on machines with bigger page size (like ppc) this can be seen more often (especially xfstest generic/127) Signed-off-by: Lukas Czerner Signed-off-by: Theodore Ts'o Cc: stable@vger.kernel.org --- fs/ext4/extents_status.c | 8 ++++++++ fs/ext4/inode.c | 2 ++ 2 files changed, 10 insertions(+) diff --git a/fs/ext4/extents_status.c b/fs/ext4/extents_status.c index d33d5a6852b9..26724aeece73 100644 --- a/fs/ext4/extents_status.c +++ b/fs/ext4/extents_status.c @@ -703,6 +703,14 @@ int ext4_es_insert_extent(struct inode *inode, ext4_lblk_t lblk, BUG_ON(end < lblk); + if ((status & EXTENT_STATUS_DELAYED) && + (status & EXTENT_STATUS_WRITTEN)) { + ext4_warning(inode->i_sb, "Inserting extent [%u/%u] as " + " delayed and written which can potentially " + " cause data loss.\n", lblk, len); + WARN_ON(1); + } + newes.es_lblk = lblk; newes.es_len = len; ext4_es_store_pblock_status(&newes, pblk, status); diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index f6b35d8a4a5b..4415cea85ced 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -532,6 +532,7 @@ int ext4_map_blocks(handle_t *handle, struct inode *inode, status = map->m_flags & EXT4_MAP_UNWRITTEN ?

While using barrier() works well for the case of gcc, recent efforts from LLVMLinux people suggest to use llvm as an alternative to gcc, and there, Stephan found in a simple stand-alone user space example that llvm could nevertheless optimize and thus elimitate the memset(). A similar issue has been observed in the referenced llvm bug report, which is regarded as not-a-bug. Based on some experiments, icc is a bit special on its own, while it doesn't seem to eliminate the memset(), it could do so with an own implementation, and then result in similar findings as with llvm. The fix in this patch now works for all three compilers (also tested with more aggressive optimization levels). Arguably, in the current kernel tree it's more of a theoretical issue, but imho, it's better to be pedantic about it. It's clearly visible with gcc/llvm though, with the below code: if we would have used barrier() only here, llvm would have omitted clearing, not so with barrier_data() variant: static inline void memzero_explicit(void *s, size_t count) { memset(s, 0, count); barrier_data(s); } int main(void) { char buff[20]; memzero_explicit(buff, sizeof(buff)); return 0; } $ gcc -O2 test.c $ gdb a.out (gdb) disassemble main Dump of assembler code for function main: 0x0000000000400400 <+0>: lea -0x28(%rsp),%rax 0x0000000000400405 <+5>: movq $0x0,-0x28(%rsp) 0x000000000040040e <+14>: movq $0x0,-0x20(%rsp) 0x0000000000400417 <+23>: movl $0x0,-0x18(%rsp) 0x000000000040041f <+31>: xor %eax,%eax 0x0000000000400421 <+33>: retq End of assembler dump. $ clang -O2 test.c $ gdb a.out (gdb) disassemble main Dump of assembler code for function main: 0x00000000004004f0 <+0>: xorps %xmm0,%xmm0 0x00000000004004f3 <+3>: movaps %xmm0,-0x18(%rsp) 0x00000000004004f8 <+8>: movl $0x0,-0x8(%rsp) 0x0000000000400500 <+16>: lea -0x18(%rsp),%rax 0x0000000000400505 <+21>: xor %eax,%eax 0x0000000000400507 <+23>: retq End of assembler dump. As gcc, clang, but also icc defines __GNUC__, it's sufficient to define this in compiler-gcc.h only to be picked up. For a fallback or otherwise unsupported compiler, we define it as a barrier. Similarly, for ecc which does not support gcc inline asm.

However, it broke the sound card support on (at least) a vintage IBM ThinkPad 600E: with said commit applied, two of the necessary "CSC01xx" devices are not added to the PNP bus and hence can not be found during the initialization of the "snd-cs4236" module. As a consequence, loading "snd-cs4236" causes null pointer exceptions. The attached patch fixes the problem end re-enables sound on the IBM ThinkPad 600E.

Turns out this is because of erratum i531 "Extra Power Consumed When Repeated Start Operation Mode Is Enabled on I2C Interface Dedicated for Smart Reflex (I2C4)" as pointed out by Nishanth Menon . Let's fix the issue by adding i2c_cfg_clear_mask for the bits to clear when initializing the I2C4 adapter so we can clear SREN bit that drives the I2C4 lines low otherwise when there is no traffic.

While this behavior is stupid and the language around this area in rfc5661 is a mess carified by an errata that I submittted, Trond insists on this behavior. Not caching deviceids degrades block layout performance massively as a GETDEVICEINFO is fairly expensive. So add this hack to make the Linux client happy again.

In theory the information is all there in current data structures, but it's not efficiently available; nfs4_file->fi_ref includes references on the file across all clients, but we need a per-(client, file) count. Walking through lots of stateid's to calculate this on each close or delegreturn would be painful. This patch introduces infrastructure to maintain per-client opens and delegation counters on a per-file basis.

Attaching a scratch buffer to the decoding xdr_stream helps deal with those cases. The case where we saw this was actually due to behavior that's been fixed in newer gss-proxy versions, but we're fixing it here too.

Upon closer inspection, there are a few minor differences causing an incorrect decoding and reporting of the master NIU upon an error: 1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies 11 bits on OMAP5 as against 8 bits on OMAP4, with the master NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR field. 2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3 input sources on OMAP5. The common DEBUGSS source is at a different input on each SoC.

The code in __netdev_upper_dev_link() has an over-stringent loop detection logic that actually prevents valid configurations from working correctly. In particular, the logic returns an error if an upper device is already in the list of all upper devices for a given dev. This particular check seems to be a overzealous as it disallows perfectly valid configurations. For example: # ip l a link eth0 name eth0.10 type vlan id 10 # ip l a dev br0 typ bridge # ip l s eth0.10 master br0 # ip l s eth0 master br0 <--- Will fail If you switch the last two commands (add eth0 first), then both will succeed. If after that, you remove eth0 and try to re-add it, it will fail! It appears to be enough to simply check adj_list to keeps things safe. I've tried stacking multiple devices multiple times in all different combinations, and either rx_handler registration prevented the stacking of the device linking cought the error.

Currently, the code that checks whether there are any waiters rely on tail value being greater than head. However, this is not true if tail reaches the max value and wraps back to zero, so arch_spin_is_contended() incorrectly returns 0 (not contended) when tail is smaller than head. The original code (before regression) handled this case by casting the (tail - head) to an unsigned value. This change simply restores that behavior.

It turns out that there are a couple of problems with the way we're fixing up branch instructions used as part of alternative instruction sequences: (1) If the branch target is also in the alternative sequence, we'll generate a branch into the .altinstructions section which actually gets freed. (2) The calls to aarch64_insn_{read,write} bring an awful lot more code into the patching path (e.g. taking locks, poking the fixmap, invalidating the TLB) which isn't actually needed for the early patching run under stop_machine, but makes the use of alternative sequences extremely fragile (as we can't patch code that could be used by the patching code). Given that no code actually requires alternative patching of immediate branches, let's remove this support for now and revisit it when we've got a user.

So fail a device open if the device configuration doesn't meet the requirements. The reason for these restictions has to do with the fact that IQ qid X has a UGTS register in the same bar2 page as EQ qid X. Thus both qids need to be allocated to the same user process for security reasons. The logic that does this (the qpid allocator in iw_cxgb4/resource.c) handles this but requires the above restrictions.

The qib driver uses a mmap() special case for when PAT is not used, this behaviour used to be determined with a module parameter but since we have been asked to just remove that module parameter this checks for the WC cookie, if not set we can assume PAT was used. If its set we do what we used to do for the mmap for when MTRR was enabled. The removal of the module parameter is OK given that Andy notes that even if users of module parameter are still around it will not prevent loading of the module on recent kernels.

The 15" pre-retina models shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz) as a BTO option, both versions used dual channel LVDS even though the smaller one would have fit into a single channel. Notes: Bug report showing that the MacBookPro8,2 with 1440x900 uses dual channel LVDS (this lead to it being hardcoded in intel_lvds.c by Daniel Vetter with commit 618563e3945b9d0864154bab3c607865b557cecc): https://bugzilla.kernel.org/show_bug.cgi?id=42842 If i915.lvds_channel_mode=2 is missing even though the machine needs it, every other vertical line is white and consequently, only the left half of the screen is visible (verified by myself on a MacBookPro9,1). Forum posting concerning a MacBookPro6,2 with 1440x900, author is using i915.lvds_channel_mode=2 on the kernel command line, proving that the machine uses dual channels: https://bbs.archlinux.org/viewtopic.php?id=185770 Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all MacBook Pro "A1286" models, and that model number encompasses the MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's driven with dual channel LVDS: http://www.ebay.com/itm/-/400690878560 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286 http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones with i915 graphics and dual channel LVDS, so that list should be complete. And the 8,2 is already in intel_lvds.c. Possible motivation to use dual channel LVDS even on the 1440x900 models: Reduce the number of different parts, i.e. use identical logic boards and display cabling on both versions and the only differing component is the panel.

The problem which that commit attempts to fix actually lies in the Freescale CAAM crypto driver not dm-crypt. dm-crypt uses CRYPTO_TFM_REQ_MAY_BACKLOG. This means the the crypto driver should internally backlog requests which arrive when the queue is full and process them later. Until the crypto hw's queue becomes full, the driver returns -EINPROGRESS. When the crypto hw's queue if full, the driver returns -EBUSY, and if CRYPTO_TFM_REQ_MAY_BACKLOG is set, is expected to backlog the request and process it when the hardware has queue space. At the point when the driver takes the request from the backlog and starts processing it, it calls the completion function with a status of -EINPROGRESS. The completion function is called (for a second time, in the case of backlogged requests) with a status/err of 0 when a request is done. Crypto drivers for hardware without hardware queueing use the helpers, crypto_init_queue(), crypto_enqueue_request(), crypto_dequeue_request() and crypto_get_backlog() helpers to implement this behaviour correctly, while others implement this behaviour without these helpers (ccp, for example). dm-crypt (before the patch that needs reverting) uses this API correctly. It queues up as many requests as the hw queues will allow (i.e. as long as it gets back -EINPROGRESS from the request function). Then, when it sees at least one backlogged request (gets -EBUSY), it waits till that backlogged request is handled (completion gets called with -EINPROGRESS), and then continues. The references to af_alg_wait_for_completion() and af_alg_complete() in that commit's commit message are irrelevant because those functions only handle one request at a time, unlink dm-crypt. The problem is that the Freescale CAAM driver, which that commit describes as having being tested with, fails to implement the backlogging behaviour correctly. In cam_jr_enqueue(), if the hardware queue is full, it simply returns -EBUSY without backlogging the request. What the observed deadlock was is not described in the commit message but it is obviously the wait_for_completion() in crypto_convert() where dm-crypto would wait for the completion being called with -EINPROGRESS in the case of backlogged requests. This completion will never be completed due to the bug in the CAAM driver. Commit 0618764cb25 incorrectly made dm-crypt wait for every request, even when the driver/hardware queues are not full, which means that dm-crypt will never see -EBUSY. This means that that commit will cause a performance regression on all crypto drivers which implement the API correctly. Revert it. Correct backlog handling should be implemented in the CAAM driver instead. Cc'ing stable purely because commit 0618764cb25 did. If for some reason a stable@ kernel did pick up commit 0618764cb25 it should get reverted.

Distributions like Ubuntu uses klibc (rather than uswsusp) to resume system from hibernation. klibc expressed the swap partition/file in the form of major:minor:offset. For example, 8:3:0 represents a swap partition in klibc, and klibc's resume process in initrd will finally echo 8:3:0 to /sys/power/resume for manually resuming. However, due to commit 283e7ad02's stricter checking, 8:3:0 will be treated as an invalid device format, and manual resuming from hibernation will fail. Fix this by adding support for devices with major:minor:offset format when resuming from hibernation. Reported-by: Prigent, Christophe Signed-off-by: Chen Yu Acked-by: Rafael J.

If this happens and the guest uses 2-level events it is possible for the interrupt to be claimed by wrong VCPU since cpu_evtchn_mask bits may be stale. This can happen even though evtchn_2l_bind_to_cpu() attempts to clear old bits: irq_info that is passed in is not necessarily the original one (from pre-migration times) but instead is freshly allocated during resume and so any information about which CPU the channel was bound to is lost. Thus we should clear the mask during resume. We also need to make sure that bits for xenstore and console channels are set when these two subsystems are resumed. While rebind_evtchn_irq() (which is invoked for both of them on a resume) calls irq_set_affinity(), the latter will in fact postpone setting affinity until handling the interrupt. But because cpu_evtchn_mask will have bits for these two cleared we won't be able to take the interrupt. With that in mind, we need to bind those two channels explicitly in rebind_evtchn_irq(). We will keep irq_set_affinity() so that we have a pass through generic irq affinity code later, in case something needs to be updated there as well. (Also replace cpumask_of(0) with cpumask_of(info->cpu) in rebind_evtchn_irq(): it should be set to zero in preceding xen_irq_info_evtchn_setup().)

This breaks Xen PV guests who do not want to load SS with__KERNEL_DS. Since the problem that the commit is trying to address would have to be fixed in the hypervisor (if it in fact exists under Xen) there is no reason to set X86_BUG_SYSRET_SS_ATTRS flag for PV VPCUs here. This can be easily achieved by adding x86_hyper_xen_hvm.set_cpu_features op which will clear this flag. (And since this structure is no longer HVM-specific we should do some renaming).

But we should do this for a thp tail page too. Consider that a memory error hits a thp tail page whose head page is on a pcplist when memory_failure() runs. Then, the current kernel skips shake_pages() part, so hwpoison_user_mappings() returns without calling split_huge_page() nor try_to_unmap() because PageLRU of the thp head is still cleared due to the skip of shake_page(). As a result, me_huge_page() runs for the thp, which is broken behavior. One effect is a leak of the thp. And another is to fail to isolate the memory error, so later access to the error address causes another MCE, which kills the processes which used the thp. This patch fixes this problem by calling shake_page() for thp tail case.

However due to hardware constraints, setting the RTC time involves sleeping during 100ms. This sleep was done outside the critical section protected by the spinlock, so it was possible to read the RTC TIME register and get an incorrect value. This patch introduces a mutex for protecting the RTC TIME access, unlike the spinlock it is allowed to sleep in a critical section protected by a mutex. The RTC STATUS register can still be used from the interrupt handler but it has no effect on setting the time.

This seems to break things for me - the Go 1.4 test suite fails all over the place with floating point comparision errors (offending commit found through bisection). The functional change was that flush_thread() after this commit only calls restore_init_xstate() when both use_eager_fpu() and !used_math() are true. drop_init_fpu() (now fpu_reset_state()) calls restore_init_xstate() regardless of whether current used_math() - apply the same logic here. Switch used_math() -> tsk_used_math(tsk) to consistently use the grabbed tsk instead of current, like in the rest of flush_thread().

In the case where HZ is 1000 the values are the same. However, for smaller HZ values the timeout is now smaller, 1s instead of 10s in the case of HZ=100. Since the timeout occurs in spite of a normal data transfer a timeout of 10s seems more appropriate. This restores the previous timeout in the case where HZ=100 and results in an increase over the previous timeout for larger values of HZ.

That was how the world was when (57291ce pinctrl: core device tree mapping table parsing support) was written. In that case, there were instances where the pinctrl mutex was already held when pinctrl_register_map() was called, hence a "locked" parameter was passed to the function to indicate that the mutex was already locked (so we shouldn't lock it again). A few years ago in (42fed7b pinctrl: move subsystem mutex to pinctrl_dev struct), we switched to a separate pinctrl_maps_mutex. ...but (oops) we forgot to re-think about the whole "locked" parameter for pinctrl_register_map(). Basically the "locked" parameter appears to still refer to whether the bigger pinctrl_dev mutex is locked, but we're using it to skip locks of our (now separate) pinctrl_maps_mutex. That's kind of a bad thing(TM). Probably nobody noticed because most of the calls to pinctrl_register_map happen at boot time and we've got synchronous device probing. ...and even cases where we're asynchronous don't end up actually hitting the race too often. ...but after banging my head against the wall for a bug that reproduced 1 out of 1000 reboots and lots of looking through kgdb, I finally noticed this. Anyway, we can now safely remove the "locked" parameter and go back to a war-free, evil-free, and kernel-bug-free world.

But it only added support for controls based on the mixer abstraction. This patch add support for mux controls (DAPM controls based on the enum abstraction) to be auto-disabled as well. As each mux can only have a single control, there is no need to tie the autodisable widget to the inputs (as is done for the mixer controls) it can be tided directly to the mux widget itself. Note that it is assumed that the first entry in a autodisable mux control will always represent the off state for the mux and is what the mux will be set to whilst it is disabled.

Where a mux has multiple input and one output and selects one of the inputs to be connected to the output, the demux has one input and multiple outputs and selects one of the outputs to which the input gets connected. This similarity makes it straight forward to support them in DAPM using the existing mux support, we only need to swap sinks and sources when initially setting up the paths. The only slightly tricky part is that there can only be one control per path. Since mixers/muxes are at the sink of a path and a demux is at the source and both types want a control it is not possible to directly connect a demux output to a mixer/mux input. The patch adds some sanity checks to make sure that this does not happen. Drivers who want to model hardware which directly connects a demux output to a mixer/mux input can do this by inserting a dummy widget between the two.

The Logitech TK820 seems to be affected by a firmware bug which delays the sending of the keys (pressed, or released, which triggers a key-repeat) while holding fingers on the touch sensor. This behavior can be observed while using the mouse emulation mode if the user moves the finger while typing (highly improbable though). Holding the finger still while in the mouse emulation mode does not trigger the key repeat problem. So better keep things in their previous state to not have to explain users that the new key-repeat bug they see is a "feature". Furthermore, I noticed that I disabled the media keys whith this patch. Sorry, my bad. I think it is best to revert the patch, in all the current versions it has been shipped.

On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence.

There is no need for special handling of stripe-batches when the array is degraded. There may be if there is a failure in the batch, but STRIPE_DEGRADED does not imply an error. So don't set STRIPE_BATCH_ERR in ops_run_io just because the array is degraded. This actually causes a bug: the STRIPE_DEGRADED flag gets cleared in check_break_stripe_batch_list() and so the bitmap bit gets cleared when it shouldn't. So in check_break_stripe_batch_list(), split the batch up completely - again STRIPE_DEGRADED isn't meaningful. Also don't set STRIPE_BATCH_ERR when there is a write error to a replacement device. This simply removes the replacement device and requires no extra handling.

I ran into this when a program was failing pthread_setaffinity_np() with EINVAL after a suspend+wake up. A simple reproducer: $ ./a.out sched_setaffinity: Success $ systemctl suspend $ ./a.out sched_setaffinity: Invalid argument ... where ./a.out is: #define _GNU_SOURCE #include #include #include #include #include #include int main(void) { long num_cores; cpu_set_t cpu_set; int ret; num_cores = sysconf(_SC_NPROCESSORS_ONLN); CPU_ZERO(&cpu_set); CPU_SET(num_cores - 1, &cpu_set); errno = 0; ret = sched_setaffinity(getpid(), sizeof(cpu_set), &cpu_set); perror("sched_setaffinity"); return ret ? EXIT_FAILURE : EXIT_SUCCESS; } The mistake is that suspend is handled in the action == CPU_DOWN_PREPARE_FROZEN case of the switch statement in cpuset_cpu_inactive(). However, the commit in question masked out CPU_TASKS_FROZEN from the action, making this case dead. The fix is straightforward.

This leads to convesion on the incorrect channel during triggered capture. Fix this by using a scan index to channel mapping encoded in the iio_chan_spec for this purpose while starting conversion on a particular ADC channel in trigger handler. Also, the channel_map is not really used anywhere but in probe(), so no need to keep track of it. Remove it from device structure.

Perform two successive reads to BGAP_DTEMP bit field. (a) If read1 returns Val1 and read2 returns Val1, then right value is Val1. (b) If read1 returns Val1, read 2 returns Val2, a third read is needed. 2. Perform third read (a) If read3 returns Val2 then right value is Val2. (b) If read3 returns Val3, then right value is Val3. The above in gist means if val1 and val2 are the same then we can go ahead with that value else we need a third read which will be right since synchronization will be complete by then.

A setup with several cameras and other devices can fill up the event ring as it is shared between all devices. This has occurred when uvcvideo queues 5 * 32TD URBs which then get cancelled when the video mode changes. The cancelled URBs are returned in the xhci interrupt context and blocks the interrupt handler from handling the new events. A full event ring will block xhci from scheduling traffic and affect all devices conneted to the xhci, will see errors such as Missed Service Intervals for isoc devices, and and Split transaction errors for LS/FS interrupt devices. Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring size, which is welcome as for most isoc transfer we had to dynamically expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo queues.

Jakub Kiciński observed that this patch can cause the pl011 driver to hang if if the only process with a pl011 port open is killed by a signal, pl011_shutdown() can get called with an arbitrary amount of data still in the FIFO. Calling _shutdown() with the TX FIFO non-empty is questionable behaviour and my itself be a bug. Since the affected patch was speculative anyway, and brings limited benefit, the simplest course is to remove the assumption that TXIS will always be left asserted after the port is shut down.

If there are only IPv6 source specific default routes present, the host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail calls ip6_route_output first, and given source address any, it fails, and ip6_route_get_saddr is never called. The change is to use the ip6_route_get_saddr, even if the initial ip6_route_output fails, and then doing ip6_route_output _again_ after we have appropriate source address available. Note that this is '99% fix' to the problem; a correct fix would be to do route lookups only within addrconf.c when picking a source address, and never call ip6_route_output before source address has been populated.

When running RDS over TCP, the active (client) side connects to the listening ("passive") side at the RDS_TCP_PORT. After the connection is established, if the client side reboots (potentially without even sending a FIN) the server still has a TCP socket in the esablished state. If the server-side now gets a new SYN comes from the client with a different client port, TCP will create a new socket-pair, but the RDS layer will incorrectly pull up the old rds_connection (which is still associated with the stale t_sock and RDS socket state). This patch corrects this behavior by having rds_tcp_accept_one() always create a new connection for an incoming TCP SYN. The rds and tcp state associated with the old socket-pair is cleaned up via the rds_tcp_state_change() callback which would typically be invoked in most cases when the client-TCP sends a FIN on TCP restart, triggering a transition to CLOSE_WAIT state. In the rarer event of client death without a FIN, TCP_KEEPALIVE probes on the socket will detect the stale socket, and the TCP transition to CLOSE state will trigger the RDS state cleanup.

Donenfeld" Date: Wed, 6 May 2015 15:09:40 +0200 Subject: [PATCH 0687/1302] usbnet: avoid integer overflow in start_xmit transfer_buffer_length is of type u32. It's therefore wrong to assign it to a signed integer. This patch avoids the overflow. It's worth noting that entry->length here is a long; perhaps it would be beneficial at somepoint to change this to be unsigned as well, if nothing else relies on its signedness for error conditions or the like.

So we do the cleanup work in .cleanup callback instead. dlci will be last put in two call chains. 1) gsmld_close -> gsm_cleanup_mux -> gsm_dlci_release -> dlci_put 2) gsmld_remove -> dlci_put so there is a race. the memory leak depends on the race. In call chain 2. we hit the memory leak. below comment tells. release_tty -> tty_driver_remove_tty -> gsmtty_remove -> dlci_put -> tty_port_destructor (WARN_ON(port->itty) and return directly) | tty->port->itty = NULL; | tty_kref_put ---> release_one_tty -> gsmtty_cleanup (added by our patch) So our patch fix the memory leak by doing the cleanup work after tty core did.

For example, pty slave | input worker | pty master | | | | n_tty_read() pty_write() | | input avail? no add data | | sleep schedule worker --->| | . |---> flush_to_ldisc() | . pty_close() | fill read buffer | . wait for worker | wakeup reader --->| . | read buffer full? |---> input avail ? yes |<--- yes - exit worker | copy 4096 bytes to user TTY_OTHER_CLOSED <---| |<--- kick worker | | **** New read() before worker starts **** | | n_tty_read() | | input avail? no | | TTY_OTHER_CLOSED? yes | | return -EIO Several conditions are required to trigger this race: 1. the ldisc read buffer must become full so the input worker exits 2. the read() count parameter must be >= 4096 so the ldisc read buffer is empty 3. the subsequent read() occurs before the kicked worker has processed more input However, the underlying cause of the race is that data is pipelined, while tty state is not; ie., data already written by the pty slave end is not yet visible to the pty master end, but state changes by the pty slave end are visible to the pty master end immediately. Pipeline the TTY_OTHER_CLOSED state through input worker to the reader. 1. Introduce TTY_OTHER_DONE which is set by the input worker when TTY_OTHER_CLOSED is set and either the input buffers are flushed or input processing has completed. Readers/polls are woken when TTY_OTHER_DONE is set. 2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED. 3. A new input worker is started from pty_close() after setting TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be set if the last input worker is already finished (or just about to exit). Remove tty_flush_to_ldisc(); no in-tree callers.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make sure that after vblank irq off, we return the last valid (vblank count, vblank timestamp) pair to clients, e.g., during modesets, which is good. An overlooked side effect of that commit for kms drivers without support for precise vblank timestamping is that at vblank irq enable, when we update the vblank counter from the hw counter, we can't update the corresponding vblank timestamp, so now we have a totally mismatched timestamp for the new count to confuse clients. Restore old client visible behaviour from before Linux 3.17, but zero out the timestamp at vblank counter update (instead of disable as in original implementation) if we can't generate a meaningful timestamp immediately for the new vblank counter. This will fix this regression, so callers know they need to retry again later if they need a valid timestamp, but at the same time preserves the improvements made in the commit mentioned above.

The ARM JIT code emits "ldr rX, [pc, #offset]" to access the literal pool. #offset maximum value is 4095 and if the generated code is too large, the #offset value can overflow and not point to the expected slot in the literal pool. Additionally, when overflow occurs, bits of the overflow can end up changing the destination register of the ldr instruction. Fix that by detecting the overflow in imm_offset() and setting a flag that is checked for each BPF instructions converted in build_body(). As of now it can only be detected in the second pass. As a result the second build_body() call can now fail, so add the corresponding cleanup code in that case. Using multiple literal pools in the JITed code is going to require lots of intrusive changes to the JIT code (which would better be done as a feature instead of fix), just delegating to the kernel BPF interpreter in that case is a more straight forward, minimal fix and easy to backport.

During pm_resume, We are submitting batchbuffers before enabling Interrupts this is causing us to miss the context switch interrupt, and in consequence intel_execlists_handle_ctx_events is not triggered. This patch is based on a patch from Deepak S from another platform. The patch fixes an issue introduced by: commit e7778be1eab918274f79603d7c17b3ec8be77386 drm/i915: Fix startup failure in LRC mode after recent init changes The above patch added a call to init_context() to fix an issue introduced by a previous patch. But, it then opened up a small timing window for the batches being added by the init_context (basically setting up the context) to complete before the interrupts have been turned on, thus hanging the GPU.

However attempting to do this a second time triggers an assertion at drop_outstanding_extent() because we have no more outstanding extents for our inode cache's inode. If we were able to start writeback of the cache the reserved metadata space is released at btrfs_finished_ordered_io(), even if an error happens during writeback. So make sure we don't repeat the metadata space release if writeback started for our inode cache. This issue was trivial to reproduce by running the fstest btrfs/088 with "-o inode_cache", which triggered the assertion leading to a BUG() call and requiring a reboot in order to run the remaining fstests.

This left a short time window where if some other task attempts to start the writeout for the same block group cache it can attempt to add a new ordered extent, starting at the same offset (0) before the previous one is removed from the ordered tree, causing an ordered tree panic (calls BUG()). This normally doesn't happen in other write paths, such as buffered writes or direct IO writes for regular files, since before marking page ranges dirty we lock the ranges and wait for any ordered extents within the range to complete first. Fix this by making btrfs_wait_ordered_range() not return immediately if it gets an error from the writeback, waiting for all ordered extents to complete first.

The first phase adds the block_group_cache_item to a list of pending block groups in the transaction handle, and phase 2 happens when btrfs_end_transaction() is called against the transaction handle. It happens that once phase 1 completes, other concurrent tasks that use their own transaction handle, but points to the same running transaction (struct btrfs_trans_handle->transaction), can use this block group for space allocations and therefore mark it dirty. Dirty block groups are tracked in a list belonging to the currently running transaction (struct btrfs_transaction) and not in the transaction handle (btrfs_trans_handle). This is a problem because once a task calls btrfs_commit_transaction(), it calls btrfs_start_dirty_block_groups() which will see all dirty block groups and attempt to start their writeout, including those that are still attached to the transaction handle of some concurrent task that hasn't called btrfs_end_transaction() yet - which means those block groups haven't gone through phase 2 yet and therefore when write_one_cache_group() is called, it won't find the block group items in the extent tree and abort the current transaction with -ENOENT, turning the fs into readonly mode and require a remount. Fix this by ignoring -ENOENT when looking for block group items in the extent tree when we attempt to start the writeout of the block group caches outside the critical section of the transaction commit. We will try again later during the critical section and if there we still don't find the block group item in the extent tree, we then abort the current transaction.

For the SMMU, we only care about TTBR0 and, in the case of a 48-bit virtual space, we expect to map virtual addresses 0x0 through to 0xffff_ffff_ffff. Given that some masters may be incapable of emitting virtual addresses targetting TTBR1 (e.g. because they sit on a 48-bit bus), the SMMU architecture allows bit 47 to be sign-extended, halving the virtual range of TTBR0 but allowing TTBR1 to be used. This is controlled by the SEP field in TTBCR2. The SMMU driver incorrectly enables this sign-extension feature, which causes problems when userspace addresses are programmed into a master device with the SMMU expecting to map the incoming transactions via TTBR0; if the top bit of address is set, we will instead get a translation fault since TTBR1 walks are disabled in the TTBCR. This patch fixes the issue by disabling sign-extension of a fixed virtual address bit and instead basing the behaviour on the upstream bus size: the incoming address is zero extended unless the upstream bus is only 49 bits wide, in which case bit 48 is used as the sign bit and is replicated to the upper bits.

However, that patch changed the behaviour so that mce_nest count was incremented *before* setting index. This causes an off-by-one error, as get_mce_event sets index as mce_nest_count - 1 before reading mce_event. Thus get_mce_event reads bogus data, causing warnings like "Machine Check Exception, Unknown event version 0 !" and breaking MCEs handling. Restore the old behaviour and unbreak MCE handling by subtracting one from the newly incremented value. The same broken change occured in machine_check_queue_event (which set a queue read by machine_check_process_queued_event). Fix that too, unbreaking printing of MCE information.

When adding routes it is very likely, however, that adjacent routes will require adjacent widgets. For example all the routes for a mux are likely added in a block and the sink widget will be the same each time and it is also quite likely that the source widgets are sequential located in the widget list. This patch adds a cache to the DAPM context, this cache will hold the source and sink widgets from the last call to snd_soc_dapm_add_route for that context. A small search of the widget list will be made from those points for both the sink and source. Currently this search only checks both the last widget and the one adjacent to it. On wm8280 which has approximately 500 widgets and 30000 routes (one of the largest CODECs in mainline), the number of paths that hit the cache is 24000, which significantly improves probe time.

There are some drivers doing this. One example is drivers/input/serio/i8042.c that requests the interrupt like: error = request_irq(I8042_KBD_IRQ, i8042_interrupt, IRQF_SHARED, "i8042", i8042_platform_device); It assumes the interrupt is already properly configured. This is true in case of interrupts connected to the IO-APIC. However, some Intel Braswell/Cherryview based machines use a GPIO here instead for the internal keyboard controller. This is a problem because even if the pin/interrupt is properly configured, the irqchip ->irq_set_type() will never be called as the triggering flags are 0. Because of that we do not have correct interrupt flow handler set for the interrupt. Fix this by adding a custom ->irq_startup() that checks if the interrupt has no triggering type set and in that case read the type directly from the hardware and install correct flow handler along with the mapping.

In hid-sensor-hub as part of hsdev creation, a per hsdev mutex is initialized during MFD cell creation. This hsdev, which contains, mutex is part of platform data for the a cell. But platform_data is copied in platform_device_add_data() in platform.c. This copy will copy the whole hsdev structure including mutex. But once copied the magic will no longer match. So when client driver call sensor_hub_input_attr_get_raw_value, this will trigger mutex warning. So to avoid this allocate mutex dynamically. This will be same even after copy.

The SP810 System Controller selects 32kHz or 1MHz as the sources for TIM_CLK[3:0], the SP804 timer clocks. The powerup default is 32kHz but the maximum of "refclk" and "timclk" is chosen by the SP810 driver. This patch adds support for SP810 system controller and also fixes the SP804 timer clock frequency. However the SP804 driver needs to be enabled on ARM64 to test this, which requires SP804 driver to be moved out of arch/arm. Fixes: 71f867ec130e ("arm64: Add Juno board device tree.")

A default mode is selected based upon whether the ELF contains MIPS32 or MIPS64 code, but that selection is made in arch_elf_pt_proc. arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is found. If one is not found then arch_elf_pt_proc is never called, and no default overall_fp_mode value is selected. When arch_check_elf is called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both prog_req & interp_req being set to none_req. none_req matches none of the conditions for mode selection at the end of arch_check_elf, so overall_fp_mode is left untouched. Finally once mips_set_personality_fp is called the BUG() in the default case is then hit & the kernel likely panics. Fix this by moving the selection of a default overall mode to the start of arch_check_elf, which runs once per ELF executed regardless of whether it has a PT_MIPS_ABIFLAGS program header.

The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the additional space needed for the stack randomization (as defined by the value of STACK_RND_MASK) was not taken into account yet and as such, when the stack randomization code added a random offset to the stack start, the stack effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK) which then sometimes leads to out-of-stack situations and crashes. This patch fixes it by adding the maximum possible amount of memory (based on STACK_RND_MASK) which theoretically could be added by the stack randomization code to the initial stack size. That way, the user-defined stack size is always guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK). This bug is currently not visible on the metag architecture, because on metag STACK_RND_MASK is defined to 0 which effectively disables stack randomization. The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP" section, so it does not affect other platformws beside those where the stack grows upwards (parisc and metag).

And when a ktime helper was changed to utilize ktime_divns, it caused a regression on some IR blasters. See the following bugzilla for details: https://bugzilla.redhat.com/show_bug.cgi?id=1200353 This patch fixes the problem in ktime_divns by checking and preserving the sign bit, and then reapplying it if appropriate after the division, it also changes the return type to a s64 to make it more obvious this is expected. Nicolas also pointed out that negative dividers would cause infinite loops on 32bit systems, negative dividers is unlikely for users of this function, but out of caution this patch adds checks for negative dividers for both 32-bit (BUG_ON) and 64-bit(WARN_ON) versions to make sure no such use cases creep in.

On success, nfs_commit_inode() can return a positive result; see other call sites such as nfs_file_fsync_commit() and nfs_commit_unstable_pages(). The call site recently added in nfs_wb_all() does not prevent that positive return value from leaking to its callers. If it leaks through nfs_sync_inode() back to nfs_getattr(), that causes stat(2) to return a positive return value to user space while also not filling in the passed-in struct stat. Additional clean up: the new logic in nfs_wb_all() is rewritten in bfields-normal form. Fixes: 5bb89b4702e2 ("NFSv4.1/pnfs: Separate out metadata . . .")

The test run took a while and hasn't finished after close to 2 hours. The crash happened right after I gave up and killed the test (after 107m) with Ctrl+C." The crash happened because a NULL inode pointer got passed into locks_get_lock_context. The call chain indicates that file_inode(filp) returned NULL, which means that f_inode was NULL. Since that's zeroed out in __fput, that suggests that this filp pointer outlived the last reference. Looking at the code, that seems possible. We copy the struct file_lock that's passed in, but if the task is signalled at an inopportune time we can end up trying to use that file_lock in rpciod context after the process that requested it has already returned (and possibly put its filp reference). Fix this by taking an extra reference to the filp when we allocate the lock info, and put it in nfs4_lock_release.

First suspend worked fine but the next one hang just after powering down of secondary CPUs (system consumed energy as it would be running but was not responsive). The issue was caused by enabling delayed reset assertion for CPU0 just after issuing power down of cores. This was introduced for Exynos4 in 13cfa6c4f7fa ("ARM: EXYNOS: Fix CPU idle clock down after CPU off"). The whole behavior is not well documented but after checking with vendor code this should be done like this (on Exynos4): 1. Enable delayed reset assertion when system is running (for all CPUs). 2. Disable delayed reset assertion before suspending the system. This can be done after powering off secondary CPUs. 3. Re-enable the delayed reset assertion when system is resumed.

This last function makes a decision based on the value of global variable dmi_ver. The problem is that this variable is set right _after_ dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0 regardless of the actual version implemented. This causes /sys/class/dmi/id/product_uuid to always use the old ordering even on systems implementing DMI/SMBIOS 2.6 or later, which should use the new ordering. This is broken since kernel v3.8 for legacy DMI implementations and since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3 implementations with the 64-bit entry point are not affected. The first breakage does not matter much as in practice legacy DMI implementations are always for versions older than 2.6, which is when the UUID ordering changed. The second breakage is more problematic as it affects the vast majority of x86 systems manufactured since 2009.

When mapping RAM we iterate over PMD-sized chunks, creating these section mappings. Section mappings are only created when the end of a chunk is aligned to section size. Unfortunately, with classic page tables (where PMD_SIZE is 2 * SECTION_SIZE) this means that if a chunk is between 1M and 2M in size the first 1M will not be mapped despite having been accounted for in the memblock limit. This has been observed to result in page tables being allocated from unmapped memory, causing boot-time hangs. This patch modifies the memblock limit rounding to always round down to PMD_SIZE instead of SECTION_SIZE. For classic MMU this means that we will round the memblock limit down to a 2M boundary, matching the limits on section mappings, and preventing allocations from unmapped memory. For LPAE there should be no change as PMD_SIZE == SECTION_SIZE.

We handle this situation quietly in the jbd2_journal_stop() and just free the handle and exit because everything else has been done before we attempted (and failed) to restart the journal. Unfortunately there are a number of problems with that approach introduced with commit 41a5b913197c "jbd2: invalidate handle if jbd2_journal_restart() fails" First of all in ext4 jbd2_journal_stop() will be called through __ext4_journal_stop() where we would try to get a hold of the superblock by dereferencing h_transaction which in this case would lead to NULL pointer dereference and crash. In addition we're going to free the handle regardless of the refcount which is bad as well, because others up the call chain will still reference the handle so we might potentially reference already freed memory. Moreover it's expected that we'll get aborted handle as well as detached handle in some of the journalling function as the error propagates up the stack, so it's unnecessary to call WARN_ON every time we get detached handle. And finally we might leak some memory by forgetting to free reserved handle in jbd2_journal_stop() in the case where handle was detached from the transaction (h_transaction is NULL). Fix the NULL pointer dereference in __ext4_journal_stop() by just calling jbd2_journal_stop() quietly as suggested by Jan Kara. Also fix the potential memory leak in jbd2_journal_stop() and use proper handle refcounting before we attempt to free it to avoid use-after-free issues. And finally remove all WARN_ON(!transaction) from the code so that we do not get random traces when something goes wrong because when journal restart fails we will get to some of those functions.

This could crash the kernel, so fix that. However, in testing this fix, I discovered that the code to write out the revoke tables also was not correctly checking to see if the block was full -- the current offset check is fine so long as the revoke table space size is a multiple of the record size, but this is not true when either journal_csum_v[23] are set.

The following patch gives an example when accounting of a certain type of allocations to memcg can effectively result in a memory leak. This patch adds the __GFP_NOACCOUNT flag which if passed to kmalloc and friends will force the allocation to go through the root cgroup. It will be used by the next patch. Note, since in case of kmemleak enabled each kmalloc implies yet another allocation from the kmemleak_object cache, we add __GFP_NOACCOUNT to gfp_kmemleak_mask. Alternatively, we could introduce a per kmem cache flag disabling accounting for all allocations of a particular kind, but (a) we would not be able to bypass accounting for kmalloc then and (b) a kmem cache with this flag set could not be merged with a kmem cache without this flag, which would increase the number of global caches and therefore fragmentation even if the memory cgroup controller is not used. Despite its generic name, currently __GFP_NOACCOUNT disables accounting only for kmem allocations while user page allocations are always charged. To catch abusing of this flag, a warning is issued on an attempt of passing it to mem_cgroup_try_charge.

Since IDA has a layered structure, different IDs can reside on the same layer, which is currently accounted to some memory cgroup. The problem is that each kmem cache of a memory cgroup has its own directory on sysfs (under /sys/fs/kernel//cgroup). If the inode number of such a directory or any file in it gets allocated from a layer accounted to the cgroup which the cache is created for, the cgroup will get pinned for good, because one has to free all kmem allocations accounted to a cgroup in order to release it and destroy all its kmem caches. That said we must not account layers of ino_ida to any memory cgroup. Since per net init operations may create new sysfs entries directly (e.g. lo device) or indirectly (nf_conntrack creates a new kmem cache per each namespace, which, in turn, creates new sysfs entries), an easy way to reproduce this issue is by creating network namespace(s) from inside a kmem-active memory cgroup.

The cause was the check in __ip6_append_data that would attempt to use partial checksums on the packet. However, raw sockets do not initialize partial checksum fields so partial checksums can't be used. Solve this the same way IPv4 does it. raw sockets pass transhdrlen value of 0 to ip_append_data which causes the checksum to be computed in software. Use the same check in ip6_append_data (check transhdrlen).

It's then possible to have TIF_SYSCALL_TRACE added in the middle of the syscall, but ret_fast_syscall doesn't check this flag again.

This pose a problem for netfilter conntrack in state LAST_ACK, because this challenge ACK is (falsely) seen as ACKing last FIN, causing a false state transition (into TIME_WAIT). The challenge ACK is hard to distinguish from real last ACK. Thus, solution introduce a flag that tracks the potential for seeing a challenge ACK, in case a SYN packet is let through and current state is LAST_ACK. When conntrack transition LAST_ACK to TIME_WAIT happens, this flag is used for determining if we are expecting a challenge ACK.

This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.

This meant the phy_state_machine() never processed the PHY_RESUMING state change, which meant interrupts weren't enabled for the PHY. If the PHY used low-power mode (i.e. using BMCR_PDOWN), then the physical link wouldn't get powered up again. There seems no point for phy_start_aneg() to make the PHY_RESUMING --> PHY_AN transition, as the state machine will do this anyway. I'm not sure about the case where autoneg is disabled, as my patch will change behaviour so that the PHY goes to PHY_NOLINK instead of PHY_FORCING. An alternative solution would be to move the phy_config_interrupt() and phy_resume() work out of the state machine and into phy_start(). The background behind this: we're running linux v3.16.7 and from user-space we want to enable the eth port (i.e. do a SIOCSIFFLAGS ioctl with the IFF_UP flag) and immediately afterward set the interface's speed/duplex. Enabling the interface calls .ndo_open() then phy_start() and the PHY transitions PHY_HALTED --> PHY_RESUMING.

This is a problem because some users (tipc) set a ceiling on the maximum table size and when that is reached the hash table may degenerate. Others may encounter OOM when growing and if we allow insertions when that happens the hash table perofrmance may also suffer. This patch adds a new paramater insecure_max_entries which becomes the cap on the table. If unset it defaults to max_size * 2. If it is also zero it means that there is no cap on the number of elements in the table. However, the table will grow whenever the utilisation hits 100% and if that growth fails, you will get ENOMEM on insertion. As allowing oversubscription is potentially dangerous, the name contains the word insecure. Note that the cap is not a hard limit. This is done for performance reasons as enforcing a hard limit will result in use of atomic ops that are heavier than the ones we currently use. The reasoning is that we're only guarding against a gross over- subscription of the table, rather than a small breach of the limit. Signed-off-by: Herbert Xu Signed-off-by: David S.

So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf665a62 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d293233 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again.

Unfortunately io_schedule_out still uses blk_flush_plug(). This causes below output (Note, I added a might_sleep() in raid1_unplug to make it trigger faster, but the whole thing doesn't matter if I add might_sleep). In raid1/10, this can cause deadlock. This patch makes io_schedule_out always uses blk_schedule_flush_plug. This should only impact drivers (as far as I know, raid 1/10) which are sensitive to the 'from_schedule' parameter.

However, when HW reported pointer is only a few bytes smaller than expected, and when hdelta is just a little larger than half a buffer time (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged.

This code was incorrect though, since this special case doesn't exist for DRM. It stemmed from the existence of the special NV12M V4L2 format. NV12 is a bi-planar format (separate planes for luma and chroma) and V4L2 differentiates between a NV12 buffer where luma and chroma is contiguous in memory (so no data between luma/chroma), and a NV12 buffer where luma and chroma have two explicit memory locations (which is then called NV12M). This distinction doesn't exist for DRM. A bi-planar format always explicitly comes with the information about its two planes (even if these planes should be contiguous).

That is an ACK that acknowledges previously unacknowledged data. This is because upon receiving an out-of-order packet, the receiver returns the last timestamp that advances RCV_NXT, not the current timestamp of the packet in the DUPACK.

The fix is simple - we just have to clear 'ret' after we are done processing the results of find_parent_nodes(). It wasn't clear to me at first what was happening with return values in btrfs_check_shared() and find_parent_nodes() - thanks to Josef for the help on irc.

(This is now fixed in the new FPU code - but still present in stable kernels.) - FPU state corruption and ABI breakage: if signal handlers try to change the FPU state in standard format, which then the kernel tries to restore in the compacted format. These breakages are scary, but they only occur on a small number of systems that have XSAVES* CPU support. Yet we have had XSAVES support in the upstream kernel for a large number of stable kernel releases, and the fixes are involved and unproven. So do the safe resolution first: disable XSAVES* support and only use the standard xstate format. This makes the code work and is easy to backport. On top of this we can work on enabling (and testing!) proper compacted format support, without backporting pressure, on top of the new, cleaned up FPU code.

When nfnetlink_{log,queue} is loaded, if a netlink message is received after the netlink callback is registered but before the pernet_subsys is registered, the kernel will panic in the sequence nfulnl_rcv_nl_event nfnl_log_pernet net_generic BUG_ON(id == 0) where id is nfnl_log_net_id. The panic can be easily reproduced in 4.0.3 by: while true ;do modprobe nfnetlink_log ; rmmod nfnetlink_log ; done & while true ;do ip netns add dummy ; ip netns del dummy ; done & This patch moves register_pernet_subsys to earlier in nfnetlink_log_init.

There are two issues: 'dnat_took_place' made me think that this is related to -j DNAT/MASQUERADE. But thats only one part of the story. This is also relevant for SNAT when we undo snat translation in reverse/reply direction. Furthermore, I originally wanted to do this mainly to avoid storing ipv6 addresses once we make DNAT/REDIRECT work for ipv6 on bridges. However, I forgot about SNPT/DNPT which is stateless. So we can't escape storing address for ipv6 anyway. Might as well do it for ipv4 too.

IPv6 ECMP implementation is a bit different from IPv4 so that route replacement cannot work in exactly the same way. This should be a reasonable approximation: 1. If the new route is ECMP-able and there is a matching ECMP-able one already, replace it and all its siblings (if any). 2. If the new route is ECMP-able and no matching ECMP-able route exists, replace first matching non-ECMP-able (if any) or just add the new one. 3. If the new route is not ECMP-able, replace first matching non-ECMP-able route (if any) or add the new route. We also need to remove the NLM_F_REPLACE flag after replacing old route(s) by first nexthop of an ECMP route so that each subsequent nexthop does not replace previous one.

Re-enable interrupts (and power up the physical link, if powered down) 2). Update the PHY state and net-device based on the link status. There's no strict reason why #1 has to be done from within the main phy_state_machine() function. There is a risk that other changes to the PHY (e.g. setting speed/duplex, which calls phy_start_aneg()) could cause a subsequent state transition before phy_state_machine() has processed the PHY_RESUMING state change. This would leave the PHY with interrupts disabled and/or still in the BMCR_PDOWN/low-power mode. Moving enabling the interrupts and phy_resume() into phy_start() will guarantee this work always gets done. As the PHY is already in the HALTED state and interrupts are disabled, it shouldn't conflict with any work being done in phy_state_machine(). The downside of this change is that if the PHY_RESUMING state is ever entered from anywhere else, it'll also have to repeat this work. Signed-off-by: Tim Beale Signed-off-by: David S.

The Linux host is the active side and starts the connection establishment, but later decides to not go through with the connection setup and does rdma_destroy_id(). The rdma_destroy_id() eventually works its way down to cm_destroy_id() in core/cm.c, where a REJ is sent. The non-Linux system has some trouble recognizing the REJ because of: A. CM states which can't receive the REJ B. Some issues about REJ formatting (missing comm ID) ISSUE A: That part of the spec says, a Consumer Reject REJ can be sent for a connection abort, but it goes further and says: can send a REJ message with a "Consumer Reject" Reason code if they are in a CM state (i.e. REP Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows a REJ to be sent (lines 35-38). Of the states listed there in that sentence, it would seem to limit the active side to using the Consumer Reject (for the abort case) in just the REP-Rcvd and MRA-REP-Sent states. That is basically only after the active side sees a REP (or alternatively goes down the state transitions to timeout in which case a Timeout REJ is sent). As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case to the same as REQ-SENT. Essentially, make a REJ sent after getting an MRA on active side a timeout rather than Consumer- Reject, which is arguably more correct with the CM state diagrams previous to getting a REP.

First, if there are any homeless lingering requests, we now request a new osdmap even if the osdmap that is being processed brought no changes, i.e. if a given lingering request turned homeless in one of the previous epochs and remained homeless in the current epoch. Not doing so leaves us with a stale osdmap and as a result we may miss our window for reestablishing the watch and lose notifies.

Second, homeless lingering requests are now kicked just like those lingering requests whose mapping has changed. This is mainly to recognize that a homeless lingering request makes no sense and to preserve the invariant that a registered lingering request is not sitting on any of r_req_lru_item lists. This spares us a WARN_ON, which commit ba9d114ec557 ("libceph: clear r_req_lru_item in __unregister_linger_request()") tried to fix the _wrong_ way.

In retrospect it's pretty obvious that r_req_lru_item item in the case of lingering requests can be used not only for notarget, but also for unsent linkage due to how tightly actual map and enqueue operations are coupled in __map_request(). The assertion that was being silenced is taken care of in the previous ("libceph: request a new osdmap if lingering request maps to no osd") commit: by always kicking homeless lingering requests we ensure that none of them ends up on the notarget list outside of the critical section guarded by request_mutex.

This fixed failures when there was no space on the drive to allocate a new chunk, but the metadata reserves were sufficient to continue the conversion. But this ended up causing a regression when the drive had plenty of space to allocate new chunks, mostly because reduce_alloc_profile isn't using the new raid profile. Fixing btrfs_reduce_alloc_profile is a bigger patch. For now, do a partial revert of 2f0810880, and don't error out if we hit ENOSPC.

When you refer file directly on cifs client, (e.g. ls -li , cd , stat ) the function return old inode number and filetype from old inode cache, though server has different inode number or filetype. When server is Windows, cifs client has same problem. When Server is Windows , This patch fixes bug in different filetype, but does not fix bug in different inode number. Because QUERY_PATH_INFO response by Windows does not include inode number(Index Number) .

Unfortunately, that version was incomplete, and we still get this build error: drivers/clk/clk-palmas.c:46:16: error: field 'hw' has incomplete type drivers/clk/clk-palmas.c: In function 'to_palmas_clks_info': drivers/clk/clk-palmas.c:54:74: warning: initialization from incompatible pointer type [-Winc This happens only in randconfig builds that turn on MFD_PALMAS on a platform other than OMAP2+ when COMPILE_TEST is set but COMMON_CLK is not. The new approach is only 'select COMMON_CLK_PALMAS' if we know that we are on an OMAP5 platform and MFD_PALMAS is already set. This patch has survived thousands of randconfig builds and I don't see a remaining hole in the logic.

Also there is a variant to find optional gpios that returns NULL if there is no gpio instead of -ENOENT. Make use of both features to simplify the driver. This changes behaviour if gpiod_get returns -ENOSYS which is the case if CONFIG_GPIOLIB is not enabled. This is a good change because without GPIOLIB there is no way to determine if the reset gpio is specified in the device tree. And if it is it must be handled, so erroring out is the right thing to do. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.

This is due to the legacy dai naming check, which could possibly cause issues if the audio drivers written in assumption that dai->id would be always equal to dai_driver->id. This assumption is true only if the dai driver count is greater than 1, and false if dai driver count is 1. On Qcom Lpass driver we hit such issue while adding support to apq8016. The code path which falls back to legacy naming for cases where num_dai == 1 does not check if there is any valid information in the dai_driver. This patch fixes that by checking if the dai_driver has valid id and name before falling back to legacy dai naming Although the drivers can work around this issue by only using dai->driver->id, but this patch attempts to fix the actual issue.

Moreover, he bisected the change apparently introducing it to 78fd1d0ab072 ("netlink: Re-add locking to netlink_lookup() and seq walker"). The removal of synchronize_net() from the netlink socket triggering the qdisc to be removed, seems to have uncovered an RCU resp. module reference count race from the tc API. Given that RCU conversion was done after e341694e3eb5 ("netlink: Convert netlink_lookup() to use RCU protected hash table") which added the synchronize_net() originally, occasion of hitting the bug was less likely (not impossible though): When qdiscs that i) support attaching classifiers and, ii) have at least one of them attached, get deleted, they invoke tcf_destroy_chain(), and thus call into ->destroy() handler from a classifier module. After RCU conversion, all classifier that have an internal prio list, unlink them and initiate freeing via call_rcu() deferral. Meanhile, tcf_destroy() releases already reference to the tp->ops->owner module before the queued RCU callback handler has been invoked. Subsequent rmmod on the classifier module is then not prevented since all module references are already dropped. By the time, the kernel invokes the RCU callback handler from the module, that function address is then invalid. One way to fix it would be to add an rcu_barrier() to unregister_tcf_proto_ops() to wait for all pending call_rcu()s to complete. synchronize_rcu() is not appropriate as under heavy RCU callback load, registered call_rcu()s could be deferred longer than a grace period. In case we don't have any pending call_rcu()s, the barrier is allowed to return immediately. Since we came here via unregister_tcf_proto_ops(), there are no users of a given classifier anymore. Further nested call_rcu()s pointing into the module space are not being done anywhere. Only cls_bpf_delete_prog() may schedule a work item, to unlock pages eventually, but that is not in the range/context of cls_bpf anymore.

The problematic behavior before this patch is applied is as follows. The behavior was observed on the STMPE610QTR controller. Upon a physical pen-down event, the touchscreen reports one set of x-y-p coordinates and a pen-down event. After that, the pen-up polling is triggered and since the controller is not ready yet, the polling mistakenly detects a pen-up event while the physical state is still such that the pen is down on the touch surface. The pen-up handling flushes the controller FIFO, so after that, all the samples in the controller are discarded. The controller becomes ready shortly after this bogus pen-up handling and does generate again a pen-down interrupt. This time, the controller contains x-y-p samples which all read as zero. Since pressure value is zero, this set of samples is effectively ignored by userland. In the end, the driver just bounces between pen-down and bogus pen-up handling, generating no useful results. Fix this by giving the controller a bit more time before polling it for pen-up.

IThe following sequence of calls is possible: CPU A CPU B ip_rcv_finish ip_route_input_noref() ip_route_input_slow() inetdev_destroy() dst_input() With the result that a network device can be destroyed while processing an input packet. A crash was triggered with only unicast packets in flight, and forwarding enabled on the only network device. The error condition was created by the removal of the network device. As such it is likely the that error code was -EHOSTUNREACH, and the action taken by ip_error (if in_dev had been accessible) would have been to not increment any counters and to have tried and likely failed to send an icmp error as the network device is going away. Therefore handle this weird case by just dropping the packet if !in_dev. It will result in dropping the packet sooner, and will not result in an actual change of behavior.

Neighbor discoveries would not be transmitted to the other guest when both used a link-local address and a static address. This only happens when there is a MLDv2 querier in the network.

The ethtool seems to query the settings for PHY0, and use this as the base to apply the new settings to the PHY1. This is causing the other settings of the PHY 1 to be wrongly configured. The issue is caused by the '_ethtool_get_settings()' API, which gets called because of the 'ETHTOOL_GSET' command, is clearing the 'cmd' pointer (of type 'struct ethtool_cmd') by calling memset. This clears all the parameters (if any) passed for the 'ETHTOOL_GSET' cmd. So the driver's callback is always invoked with 'cmd->phy_address' as '0'. The '_ethtool_get_settings()' is called from other files in the 'net/core'. So the fix is applied to the 'ethtool_get_settings()' which is only called in the context of the 'ethtool'.

Through the regression report, it was revealed that the tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the mute LED but actually mutes the sound. This is contradiction to the expectation, and rather confuses user. According to Henrique, it's not trivial to judge which TP model behaves "LED-only" and which model does whatever more intrusive, as Lenovo's implementations vary model by model. So, from the safety reason, we should revert the patch for now.

Currently, the calibration function that corrects the initial offsets among multiple devices only works the first time. If the function is called more than once, the calibration fails and bogus offsets will be programmed into the devices. In a well hidden spot, the device documentation tells that trigger indexes 0 and 1 are special in allowing the TRIG_IF_LATE flag to actually work.

It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Direct use of __initcall is discouraged, vs prioritized ones. Use of device_initcall is consistent with what __initcall maps onto, and hence does not change the init order, making the impact of this change zero. Should someone with real hardware for boot testing want to change it later to arch_initcall or console_initcall, they can do that at a later date.

This was an accepted compromise to be able to move the GIC cleanup forward. What actually happened was that booting a new kernel on an old DT crashes before even the console is up, so the user does not even see the warning that the DT is too old. The warning message suggests that this has been known before, which is clearly unacceptable. Fix the early crash by mapping the GPC memory space if the IRQ controller doesn't claim it. This keeps at least CPUidle and the needed CPU wakeup workarounds working. With this fixed the system is able to boot up properly minus the expected suspend/resume breakage.

Zeroing the v6 flowinfo overwrites the v4 sin_addr with 0, meaning that every place that calls sctp_v4_map_v6 gets ::ffff:0.0.0.0 as the result. Reorder things to guarantee correct behaviour no matter what the union layout is. This impacts user space clients that open an IPv6 SCTP socket and receive IPv4 connections.

This cleans up the previous convoluted handling of request requeueing that would return BLK_MQ_RQ_QUEUE_OK (even though it wasn't) and then run blk_mq_requeue_request() followed by blk_mq_kick_requeue_list(). Also, document that DM blk-mq ontop of old request_fn devices cannot fail in clone_rq() since the clone request is preallocated as part of the pdu.

If it is not the case, an incorrect pointer (or a piece of data that is not a pointer at all) will be passed to ACPI_COMPANION_SET() and that may cause interesting breakage to happen going forward. To work around this problem use the observation that the ACPI host bridge initialization always passes NULL as parent to pci_create_root_bus(), so if pcibios_root_bridge_prepare() sees a non-NULL parent of the bridge, it should not attempt to set an ACPI companion for it, because that means that pci_create_root_bus() has been called by someone else.

When we add a write to a stripe we need to make sure the bitmap bit is set. While doing that the stripe is not locked so it could be added to a batch after which further changes to STRIPE_BIT_DELAY and ->bm_seq are ineffective. So we need to hold off adding to a stripe until bitmap_startwrite has completed at least once, and we need to avoid further changes to STRIPE_BIT_DELAY once the stripe has been added to a batch. If a bitmap_startwrite() completes after the stripe was added to a batch, it will not have set the bit, only incremented a counter, so no extra delay of the stripe is needed.

I never saw it before, it went through DaveM. (He only does this to make us other maintainers feel better about our own mistakes.) cpumask_set_cpu_local_first's purpose is say "I need to spread things across N online cpus, choose the ones on this numa node first"; you call it in a loop. It can fail. One of the two callers ignores this, the other aborts and fails the device open. It can fail in two ways: allocating the off-stack cpumask, or through a convoluted codepath which AFAICT can only occur if cpu_online_mask changes. Which shouldn't happen, because if cpu_online_mask can change while you call this, it could return a now-offline cpu anyway. It contains a nonsensical test "!cpumask_of_node(numa_node)". This was drawn to my attention by Geert, who said this causes a warning on Sparc. It sets a single bit in a cpumask instead of returning a cpu number, because that's what the callers want. It could be made more efficient by passing the previous cpu rather than an index, but that would be more invasive to the callers.

When a batch of stripes is broken up, we keep some of the flags that were per-stripe, and copy other flags from the head to all others. This only happens while a stripe is being handled, so many of the flags are irrelevant. The "SYNC_FLAGS" (which I've renamed to make it clear there are several) and STRIPE_DEGRADED are set per-stripe and so need to be preserved. STRIPE_INSYNC is the only flag that is set on the head that needs to be propagated to all others. For safety, add a WARN_ON if others are set, except: STRIPE_HANDLE - this is safe and per-stripe and we are going to set in several cases anyway STRIPE_INSYNC STRIPE_IO_STARTED - this is just a hint and doesn't hurt. STRIPE_ON_PLUG_LIST STRIPE_ON_RELEASE_LIST - It is a point pointless for a batched stripe to be on one of these lists, but it can happen as can be safely ignored.

So instead of clearing MD_RECOVERY_FROZEN for any command except 'frozen', only clear it when each specific command is parsed. This allows the handling of 'reshape' to clear the bit while a lock is held. Also remove some places where we set MD_RECOVERY_NEEDED, as it is always set on non-error exit of the function.

Hence the standard percpu counter batch of 32 means that the counter is effectively a global counter. Currently Xfs uses a batch size of 128 so that it doesn't take the global lock on every single modification. However, Xfs also needs to compare accurately against zero, which means we need to use percpu_counter_compare(), and that has a hard-coded batch size of 32, and hence will spuriously fail to detect when it is supposed to use precise comparisons and hence the accounting goes wrong. Add __percpu_counter_compare() to take a custom batch size so we can use it sanely in XFS and factor percpu_counter_compare() to use it.

A prior trace point shows the allocation was an exact size match and that a length greater than MAXEXTLEN was asked for: xfs_alloc_size_done: agno 1 agbno 8 minlen 2097152 maxlen 2097152 ^^^^^^^ ^^^^^^^ We don't see this problem with extent size hints through the IO path because we can't do single IOs large enough to trigger MAXEXTLEN allocation. fallocate(), OTOH, is not limited in it's allocation sizes and so needs help here. The issue is that the extent size hint alignment is rounding up the extent size past MAXEXTLEN, because xfs_bmapi_write() is not taking into account extent size hints when calculating the maximum extent length to allocate. xfs_bmapi_reserve_delalloc() is already doing this, but direct extent allocation is not. Unfortunately, the calculation in xfs_bmapi_reserve_delalloc() is wrong, and it works only because delayed allocation extents are not limited in size to MAXEXTLEN in the in-core extent tree. hence this calculation does not work for direct allocation, and the delalloc code needs fixing. This may, in fact be the underlying bug that occassionally causes transaction overruns in delayed allocation extent conversion, so now we know it's wrong we should fix it, too. Many thanks to Brian Foster for finding this problem during review of this patch. Hence the fix, after much code reading, is to allow xfs_bmap_extsize_align() to align partial extents when full alignment would extend the alignment past MAXEXTLEN. We can safely do this because all callers have higher layer allocation loops that already handle short allocations, and so will simply run another allocation to cover the remainder of the requested allocation range that we ignored during alignment. The advantage of this approach is that it also removes the need for callers to do anything other than limit their requests to MAXEXTLEN - they don't really need to be aware of extent size hints at all.

While it removes attribute fork extents, it completely ignores attributes in local format, which means that there can still be active attributes on the inode after xfs_attr_inactive() has run. This leads to problems with concurrent inode writeback - the in-core inode attribute fork is removed without locking on the assumption that nothing will be attempting to access the attribute fork after a call to xfs_attr_inactive() because it isn't supposed to exist on disk any more. To fix this, make xfs_attr_inactive() completely remove all traces of the attribute fork from the inode, regardless of it's state. Further, also remove the in-core attribute fork structure safely so that there is nothing further that needs to be done by callers to clean up the attribute fork. This means we can remove the in-core and on-disk attribute forks atomically. Also, on error simply remove the in-memory attribute fork. There's nothing that can be done with it once we have failed to remove the on-disk attribute fork, so we may as well just blow it away here anyway. cc: # 3.12 to 4.0 Reported-by: Waiman Long Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner --- fs/xfs/libxfs/xfs_attr_leaf.c | 8 ++-- fs/xfs/libxfs/xfs_attr_leaf.h | 2 +- fs/xfs/xfs_attr_inactive.c | 83 +++++++++++++++++++++-------------- fs/xfs/xfs_inode.c | 12 ++--- 4 files changed, 58 insertions(+), 47 deletions(-) diff --git a/fs/xfs/libxfs/xfs_attr_leaf.c b/fs/xfs/libxfs/xfs_attr_leaf.c index 04e79d57bca6..e9d401ce93bb 100644 --- a/fs/xfs/libxfs/xfs_attr_leaf.c +++ b/fs/xfs/libxfs/xfs_attr_leaf.c @@ -574,8 +574,8 @@ xfs_attr_shortform_add(xfs_da_args_t *args, int forkoff) * After the last attribute is removed revert to original inode format, * making all literal area available to the data fork once more. */ -STATIC void -xfs_attr_fork_reset( +void +xfs_attr_fork_remove( struct xfs_inode *ip, struct xfs_trans *tp) { @@ -641,7 +641,7 @@ xfs_attr_shortform_remove(xfs_da_args_t *args) (mp->m_flags & XFS_MOUNT_ATTR2) && (dp->i_d.di_format != XFS_DINODE_FMT_BTREE) && !(args->op_flags & XFS_DA_OP_ADDNAME)) { - xfs_attr_fork_reset(dp, args->trans); + xfs_attr_fork_remove(dp, args->trans); } else { xfs_idata_realloc(dp, -size, XFS_ATTR_FORK); dp->i_d.di_forkoff = xfs_attr_shortform_bytesfit(dp, totsize); @@ -905,7 +905,7 @@ xfs_attr3_leaf_to_shortform( if (forkoff == -1) { ASSERT(dp->i_mount->m_flags & XFS_MOUNT_ATTR2); ASSERT(dp->i_d.di_format != XFS_DINODE_FMT_BTREE); - xfs_attr_fork_reset(dp, args->trans); + xfs_attr_fork_remove(dp, args->trans); goto out; } diff --git a/fs/xfs/libxfs/xfs_attr_leaf.h b/fs/xfs/libxfs/xfs_attr_leaf.h index 025c4b820c03..882c8d338891 100644 --- a/fs/xfs/libxfs/xfs_attr_leaf.h +++ b/fs/xfs/libxfs/xfs_attr_leaf.h @@ -53,7 +53,7 @@ int xfs_attr_shortform_remove(struct xfs_da_args *args); int xfs_attr_shortform_list(struct xfs_attr_list_context *context); int xfs_attr_shortform_allfit(struct xfs_buf *bp, struct xfs_inode *dp); int xfs_attr_shortform_bytesfit(xfs_inode_t *dp, int bytes); - +void xfs_attr_fork_remove(struct xfs_inode *ip, struct xfs_trans *tp); /* * Internal routines when attribute fork size == XFS_LBSIZE(mp). diff --git a/fs/xfs/xfs_attr_inactive.c b/fs/xfs/xfs_attr_inactive.c index f9c1c64782d3..3fbf167cfb4c 100644 --- a/fs/xfs/xfs_attr_inactive.c +++ b/fs/xfs/xfs_attr_inactive.c @@ -380,23 +380,31 @@ xfs_attr3_root_inactive( return error; } +/* + * xfs_attr_inactive kills all traces of an attribute fork on an inode.

For tmpfile inodes, XFS allocates the inode, drops di_nlink, adds the inode to the agi unlinked list, calls d_tmpfile() which correspondingly drops i_nlink of the vfs inode, and then finishes the common inode setup (e.g., clear I_NEW and unlock). The d_tmpfile() call was originally made inxfs_create_tmpfile(), but was pulled up out of that function as part of the following commit to resolve a deadlock issue: 330033d6 xfs: fix tmpfile/selinux deadlock and initialize security As a result, callers of xfs_create_tmpfile() are responsible for either calling d_tmpfile() or fixing up i_nlink appropriately. The whiteout tmpfile allocation helper does neither. As a result, the vfs ->i_nlink becomes inconsistent with the on-disk ->di_nlink once xfs_rename() links it back into the source dentry and calls xfs_bumplink(). Update the assert in xfs_rename() to help detect this problem in the future and update xfs_rename_alloc_whiteout() to decrement the link count as part of the manual tmpfile inode setup.

The loop conditional expects count to be signed in order to detect when the final block is processed, after which count goes negative. Unfortunately, a recent change made this unsigned along with some other related fields. The result of is this is that during mount, omfs_get_imap will overrun the bitmap array and corrupt memory unless number of blocks happens to be a multiple of 8 * blocksize. Fix by changing count back to signed: it is guaranteed to fit in an s32 without overflow due to an enforced limit on the number of blocks in the filesystem.

Use conditional assembly to avoid a microMIPS code size regression. Using $at unconditionally would cause such a regression as there are no 16-bit instruction encodings available for ALU operations using this register. Using $v1 unconditionally would produce short microMIPS encodings, but would prevent this register from being used across calls to this function. The extra LI operation introduced is free, replacing a NOP originally scheduled into the delay slot of the branch that follows. Signed-off-by: Maciej W.

When this booster is active, the DCVDD voltage must be increased. If all the currently active audio paths can run with the root SYSCLK we can disable the booster, allowing us to turn down DCVDD voltage to save power. Previously this was being done by having the booster enable bit set as a side-effect of the LDO1 regulator driver, which is unexpected behaviour of a regulator and not compatible with using an external regulator. [Originally this was documented as a feature of the internal LDO -- broonie] This patch exports functions to handle the booster enable and DCVDD voltage, with each relevant subsystem flagging whether it can currently run without the booster. Note that these subsystems are stateless and none of them are nestable, so there's no need for reference counting, we only need a simple boolean for each subsystem of whether their current condition could require the booster or will allow us to turn the codec down to lower operating power.

The core also passes any block that is does not understand to client component drivers for enumeration. The core exports some APIs to client drivers in order to load and unload firmware topology data as use case require. Currently the core deals with the following object types :- o kcontrols. This includes TLV, enumerated and bytes controls. o DAPM widgets. All types with any associated kcontrol. o DAPM graph. o FE PCM. FE PCM capabilities and configuration can be defined. o BE DAI Link. BE DAI link capabilities and configuration can be defined. o Codec <-> codec style links capabilities and configuration.
