[PATCH] crypto: ccp - Fix use of merged scatterlists

by John Allen

Running the crypto manager self tests with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS may result in several types of errors when using the ccp-crypto driver: alg: skcipher: cbc-des3-ccp encryption failed on test vector 0; expected_error=0, actual_error=-5 ... alg: skcipher: ctr-aes-ccp decryption overran dst buffer on test vector 0 ... alg: ahash: sha224-ccp test failed (wrong result) on test vector ... These errors are the result of improper processing of scatterlists mapped for DMA. Given a scatterlist in which entries are merged as part of mapping the scatterlist for DMA, the DMA length of a merged entry will reflect the combined length of the entries that were merged. The subsequent scatterlist entry will contain DMA information for the scatterlist entry after the last merged entry, but the non-DMA information will be that of the first merged entry. The ccp driver does not take this scatterlist merging into account. To address this, add a second scatterlist pointer to track the current position in the DMA mapped representation of the scatterlist. Both the DMA representation and the original representation of the scatterlist must be tracked as while most of the driver can use just the DMA representation, scatterlist_map_and_copy() must use the original representation and expects the scatterlist pointer to be accurate to the original representation. In order to properly walk the original scatterlist, the scatterlist must be walked until the combined lengths of the entries seen is equal to the DMA length of the current entry being processed in the DMA mapped representation.

[PATCH 5/5] bpf: Check correct cred for CAP_SYSLOG in bpf_dump_raw_ok()

by Kees Cook

When evaluating access control over kallsyms visibility, credentials at open() time need to be used, not the "current" creds (though in BPF's case, this has likely always been the same). Plumb access to associated file->f_cred down through bpf_dump_raw_ok() and its callers now that kallsysm_show_value() has been refactored to take struct cred.

[PATCH v2 1/4] arm64: ptrace: Add a comment describing our syscall entry/exit trap ABI

by Will Deacon

Our tracehook logic for syscall entry/exit raises a SIGTRAP back to the tracer following a ptrace request such as PTRACE_SYSCALL. As part of this procedure, we clobber the reported value of one of the tracee's general purpose registers (x7 for native tasks, r12 for compat) to indicate whether the stop occurred on syscall entry or exit. This is a slightly unfortunate ABI, as it prevents the tracer from accessing the real register value and is at odds with other similar stops such as seccomp traps. Since we're stuck with this ABI, expand the comment in our tracehook logic to acknowledge the issue and descibe the behaviour in more detail.

[PATCH] tpm: Define TPM2_SPACE_BUFFER_SIZE to replace the use of PAGE_SIZE

by Jarkko Sakkinen

The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be enough for most use with three handles (that is how many we allow at the moment).

These preallocated extents have, and must have, the same size that extents from the data block group being relocated have. Later before we start the relocation stage that updates pointers (bytenr field of file extent items) to point to the the new extents, we trigger writeback for the data relocation inode. The expectation is that writeback will write the pages to the previously preallocated extents, that it follows the NOCOW path. That is generally the case, however, if a scrub is running it may have turned the block group that contains those extents into RO mode, in which case writeback falls back to the COW path. However in the COW path instead of allocating exactly one extent with the expected size, the allocator may end up allocating several smaller extents due to free space fragmentation - because we tell it at cow_file_range() that the minimum allocation size can match the filesystem's sector size. This later breaks the relocation's expectation that an extent associated to a file extent item in the data relocation inode has the same size as the respective extent pointed by a file extent item in another tree - in this case the extent to which the relocation inode poins to is smaller, causing relocation.c:get_new_location() to return -EINVAL. For example, if we are relocating a data block group X that has a logical address of X and the block group has an extent allocated at the logical address X + 128KiB with a size of 64KiB: 1) At prealloc_file_extent_cluster() we allocate an extent for the data relocation inode with a size of 64KiB and associate it to the file offset 128KiB (X + 128KiB - X) of the data relocation inode. This preallocated extent was allocated at block group Z; 2) A scrub running in parallel turns block group Z into RO mode and starts scrubing its extents; 3) Relocation triggers writeback for the data relocation inode; 4) When running delalloc (btrfs_run_delalloc_range()), we try first the NOCOW path because the data relocation inode has BTRFS_INODE_PREALLOC set in its flags. However, because block group Z is in RO mode, the NOCOW path (run_delalloc_nocow()) falls back into the COW path, by calling cow_file_range(); 5) At cow_file_range(), in the first iteration of the while loop we call btrfs_reserve_extent() to allocate a 64KiB extent and pass it a minimum allocation size of 4KiB (fs_info->sectorsize). Due to free space fragmentation, btrfs_reserve_extent() ends up allocating two extents of 32KiB each, each one on a different iteration of that while loop; 6) Writeback of the data relocation inode completes; 7) Relocation proceeds and ends up at relocation.c:replace_file_extents(), with a leaf which has a file extent item that points to the data extent from block group X, that has a logical address (bytenr) of X + 128KiB and a size of 64KiB. Then it calls get_new_location(), which does a lookup in the data relocation tree for a file extent item starting at offset 128KiB (X + 128KiB - X) and belonging to the data relocation inode. It finds a corresponding file extent item, however that item points to an extent that has a size of 32KiB, which doesn't match the expected size of 64KiB, resuling in -EINVAL being returned from this function and propagated up to __btrfs_cow_block(), which aborts the current transaction. To fix this make sure that at cow_file_range() when we call the allocator we pass it a minimum allocation size corresponding the desired extent size if the inode belongs to the data relocation tree, otherwise pass it the filesystem's sector size as the minimum allocation size.

When this happens we end up failing the block group creation with an error -EEXIST since we attempt to insert a duplicate block group item key in the extent tree. That results in a transaction abort. The race happens like this: 1) Task A is doing a fitrim, and at btrfs_trim_block_group() it freezes block group X with btrfs_freeze_block_group() (until very recently that was named btrfs_get_block_group_trimming()); 2) Task B starts removing block group X, either because it's now unused or due to relocation for example. So at btrfs_remove_block_group(), while holding the chunk mutex and the block group's lock, it sets the 'removed' flag of the block group and it sets the local variable 'remove_em' to false, because the block group is currently frozen (its 'frozen' counter is > 0, until very recently this counter was named 'trimming'); 3) Task B unlocks the block group and the chunk mutex; 4) Task A is done trimming the block group and unfreezes the block group by calling btrfs_unfreeze_block_group() (until very recently this was named btrfs_put_block_group_trimming()). In this function we lock the block group and set the local variable 'cleanup' to true because we were able to decrement the block group's 'frozen' counter down to 0 and the flag 'removed' is set in the block group. Since 'cleanup' is set to true, it locks the chunk mutex and removes the extent mapping representing the block group from the mapping tree; 5) Task C allocates a new block group Y and it picks up the logical address that block group X had as the logical address for Y, because X was the block group with the highest logical address and now the second block group with the highest logical address, the last in the fs mapping tree, ends at an offset corresponding to block group X's logical address (this logical address selection is done at volumes.c:find_next_chunk()). At this point the new block group Y does not have yet its item added to the extent tree (nor the corresponding device extent items and chunk item in the device and chunk trees). The new group Y is added to the list of pending block groups in the transaction handle; 6) Before task B proceeds to removing the block group item for block group X from the extent tree, which has a key matching: (X logical offset, BTRFS_BLOCK_GROUP_ITEM_KEY, length) task C while ending its transaction handle calls btrfs_create_pending_block_groups(), which finds block group Y and tries to insert the block group item for Y into the exten tree, which fails with -EEXIST since logical offset is the same that X had and task B hasn't yet deleted the key from the extent tree. This failure results in a transaction abort, producing a stack like the following: ------------[ cut here ]------------ BTRFS: Transaction aborted (error -17) WARNING: CPU: 2 PID: 19736 at fs/btrfs/block-group.c:2074 btrfs_create_pending_block_groups+0x1eb/0x260 [btrfs] Modules linked in: btrfs blake2b_generic xor raid6_pq (...)

There is a second bug where if removing the free space tree entries (the call to remove_block_group_free_space()) fails we end up jumping to the 'out_put_group' label but end up decrementing the reference count only once, when we should have done it twice, since we have already removed the block group from the block group cache rbtree. This happens because the reference count decrement for the rbtree reference happens after attempting to remove the free space tree entries, which is far away from the place where we remove the block group from the rbtree. To make things less error prone, decrement the reference count for the rbtree immediately after removing the block group from it. This also eleminates the need for two different exit labels on error, renaming 'out_put_label' to just 'out' and removing the old 'out'.

[PATCH 1/3] mm/vmscan: restore zone_reclaim_mode ABI

by Dave Hansen

From: Dave Hansen <dave.hansen(a)linux.intel.com> I went to go add a new RECLAIM_* mode for the zone_reclaim_mode sysctl. Like a good kernel developer, I also went to go update the documentation. I noticed that the bits in the documentation didn't match the bits in the #defines. The VM never explicitly checks the RECLAIM_ZONE bit. The bit is, however implicitly checked when checking 'node_reclaim_mode==0'. The RECLAIM_ZONE #define was removed in a cleanup. That, by itself is fine. But, when the bit was removed (bit 0) the _other_ bit locations also got changed. That's not OK because the bit values are documented to mean one specific thing and users surely rely on them meaning that one thing and not changing from kernel to kernel. The end result is that if someone had a script that did: sysctl vm.zone_reclaim_mode=1 That script went from doing nothing to writing out pages during node reclaim after the commit in question. That's not great. Put the bits back the way they were and add a comment so something like this is a bit harder to do again. Update the documentation to make it clear that the first bit is ignored.

drm/i915: use forced codec wake on all gen9+ platforms

by Kai Vehmanen

Hey, following commit from 5.8-rc1 would be beneficial for 5.4+ kernels. We've verified it fixes audio driver probe errors on systems with Intel gen10/11/12 display hardware: Link: https://github.com/thesofproject/linux/issues/1847 commit 1c664c15cf0a31784b217a84fa0128ce46f17a84 Author: Kai Vehmanen <kai.vehmanen(a)linux.intel.com> Date: Tue Mar 24 17:32:12 2020 +0200 drm/i915: use forced codec wake on all gen9+ platforms Commit 632f3ab95fe2 ("drm/i915/audio: add codec wakeup override enabled/disable callback"), added logic to toggle Codec Wake on gen9. This is used by audio driver when it resets the HDA controller. It seems explicit toggling of the wakeline can help to fix problems with probe failing on some gen12 platforms. And based on specs, there is no reason why this programming sequence should not be applied to all gen9+ platforms. No side-effects are seen on gen10/11. So apply the wake-logic to all gen9+ platforms.

[PATCH v2 0/1] Revert "serial: 8250: Fix max baud limit in generic 8250 port"

by Daniel Winkler

This change regresses the QCA6174A-3 bluetooth chip, preventing firmware from being properly loaded. Without this change, the chip works as intended. The device is the Kukui Chromebook using the Mediatek chipset and the 8250_mtk uart. Initial controller baudrate is 115200 and operating speed is 3000000. Our entire suite of bluetooth tests now fail on this platform due to an apparent failure to sync its firmware on initialization. The driver is in the cros tree at drivers/bluetooth/hci_qca.c and uses the serdev interface. Specifically, this is the QCA_ROME chipset.

Request for patch inclusion for 5.4-stable

by Jens Axboe

Hi, There's no upstream variant of this, as that would require backporting all the io-wq changes from 5.5 and on. Hence I made a one-off that ensures that we don't leak memory if we have async work items that need active cancelation (like socket IO). Can we get this queued up for 5.4? I've tested it and the original reporter has as well. From: Jens Axboe <axboe(a)kernel.dk> Subject: [PATCH] io_uring: make sure async workqueue is canceled on exit Track async work items that we queue, so we can safely cancel them if the ring is closed or the process exits. Newer kernels handle this automatically with io-wq, but the old workqueue based setup needs a bit of special help to get there.

[PATCH AUTOSEL 4.4 1/7] net: usb: ax88179_178a: fix packet alignment padding

by Sasha Levin

From: Jeremy Kerr <jk(a)ozlabs.org> [ Upstream commit e869e7a17798d85829fa7d4f9bbe1eebd4b2d3f6 ] Using a AX88179 device (0b95:1790), I see two bytes of appended data on every RX packet. For example, this 48-byte ping, using 0xff as a payload byte: 04:20:22.528472 IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 2447, seq 1, length 64 0x0000: 000a cd35 ea50 000a cd35 ea4f 0800 4500 0x0010: 0054 c116 4000 4001 f63e c0a8 0101 c0a8 0x0020: 0102 0800 b633 098f 0001 87ea cd5e 0000 0x0030: 0000 dcf2 0600 0000 0000 ffff ffff ffff 0x0040: ffff ffff ffff ffff ffff ffff ffff ffff 0x0050: ffff ffff ffff ffff ffff ffff ffff ffff 0x0060: ffff 961f Those last two bytes - 96 1f - aren't part of the original packet. In the ax88179 RX path, the usbnet rx_fixup function trims a 2-byte 'alignment pseudo header' from the start of the packet, and sets the length from a per-packet field populated by hardware. It looks like that length field *includes* the 2-byte header; the current driver assumes that it's excluded. This change trims the 2-byte alignment header after we've set the packet length, so the resulting packet length is correct. While we're moving the comment around, this also fixes the spelling of 'pseudo'. Signed-off-by: Jeremy Kerr <jk(a)ozlabs.org> Signed-off-by: David S.

[PATCH AUTOSEL 4.9 01/13] gpu: host1x: Detach driver on unregister

by Sasha Levin

From: Thierry Reding <treding(a)nvidia.com> [ Upstream commit d9a0a05bf8c76e6dc79230669a8b5d685b168c30 ] Currently when a host1x device driver is unregistered, it is not detached from the host1x controller, which means that the device will stay around and when the driver is registered again, it may bind to the old, stale device rather than the new one that was created from scratch upon driver registration. This in turn can cause various weird crashes within the driver core because it is confronted with a device that was already deleted. Fix this by detaching the driver from the host1x controller when it is unregistered. This ensures that the deleted device also is no longer present in the device list that drivers will bind to.

[PATCH AUTOSEL 4.14 01/17] ARM: dts: omap4-droid4: Fix spi configuration and increase rate

by Sasha Levin

From: Tony Lindgren <tony(a)atomide.com> [ Upstream commit 0df12a01f4857495816b05f048c4c31439446e35 ] We can currently sometimes get "RXS timed out" errors and "EOT timed out" errors with spi transfers. These errors can be made easy to reproduce by reading the cpcap iio values in a loop while keeping the CPUs busy by also reading /dev/urandom. The "RXS timed out" errors we can fix by adding spi-cpol and spi-cpha in addition to the spi-cs-high property we already have. The "EOT timed out" errors we can fix by increasing the spi clock rate to 9.6 MHz. Looks similar MC13783 PMIC says it works at spi clock rates up to 20 MHz, so let's assume we can pick any rate up to 20 MHz also for cpcap.

[net-next 10/12] iavf: Fix updating statistics

by Tony Nguyen

Commit bac8486116b0 ("iavf: Refactor the watchdog state machine") inverted the logic for when to update statistics. Statistics should be updated when no other commands are pending, instead they were only requested when a command was processed. iavf_request_stats() would see a pending request and not request statistics to be updated. This caused statistics to never be updated; fix the logic.

[PATCH] Drivers: hv: Change flag to write log level in panic msg to false

by Joseph Salisbury

When the kernel panics, one page worth of kmsg data is written to an allocated page. The Hypervisor is notified of the page address trough the MSR. This panic information is collected on the host. Since we are only collecting one page of data, the full panic message may not be collected. Each line of the panic message is prefixed with the log level of that particular message in the form <N>, where N is the log level. The typical 4 Kbytes contains anywhere from 50 to 100 lines with that log level prefix. hv_dmsg_dump() makes a call to kmsg_dump_get_buffer(). The second argument in the call is a bool described as: ‘@syslog: include the “<4>” Prefixes’. With this change, we will not write the log level to the allocated page. This will provide additional room in the allocated page for more informative panic information. Requesting in stable kernels, since many kernels running in production are stable releases.

patch "coresight: etmv4: Fix CPU power management setup in probe() function" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled coresight: etmv4: Fix CPU power management setup in probe() function to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 9b6a3f3633a5cc928b78627764793b60cb62e0f6 Mon Sep 17 00:00:00 2001 From: Mike Leach <mike.leach(a)linaro.org> Date: Wed, 1 Jul 2020 10:08:52 -0600 Subject: coresight: etmv4: Fix CPU power management setup in probe() function The current probe() function calls a pair of cpuhp_xxx API functions to setup CPU hotplug handling. The hotplug lock is held for the duration of the two calls and other CPU related code using cpus_read_lock() / cpus_read_unlock() calls. The problem is that on error states, goto: statements bypass the cpus_read_unlock() call. This code has increased in complexity as the driver has developed. This patch introduces a pair of helper functions etm4_pm_setup_cpuslocked() and etm4_pm_clear() which correct the issues above and group the PM code a little better. The two functions etm4_cpu_pm_register() and etm4_cpu_pm_unregister() are dropped as these call cpu_pm_register_notifier() / ..unregister_notifier() dependent on CONFIG_CPU_PM - but this define is used to nop these functions out in the pm headers - so the wrapper functions are superfluous.

[PATCH 2/3] uio_pdrv_genirq: fix use without device tree and no interrupt

by Esben Haabendal

While e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no interrupt") added support for using uio_pdrv_genirq for devices without interrupt for device tree platforms, the removal of uio_pdrv in 26dac3c49d56 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead") broke the support for non device tree platforms. This change fixes this, so that uio_pdrv_genirq can be used without interrupt on all platforms. This still leaves the support that uio_pdrv had for custom interrupt handler lacking, as uio_pdrv_genirq does not handle it (yet). Fixes: 26dac3c49d56 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead") Signed-off-by: Esben Haabendal <esben(a)geanix.com> Cc: stable(a)vger.kernel.org --- drivers/uio/uio_pdrv_genirq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/uio/uio_pdrv_genirq.c b/drivers/uio/uio_pdrv_genirq.c index 1d69dd49c6d2..b60173bc93ce 100644 --- a/drivers/uio/uio_pdrv_genirq.c +++ b/drivers/uio/uio_pdrv_genirq.c @@ -161,7 +161,7 @@ static int uio_pdrv_genirq_probe(struct platform_device *pdev) if (!uioinfo->irq) { ret = platform_get_irq_optional(pdev, 0); uioinfo->irq = ret; - if (ret == -ENXIO && pdev->dev.of_node) + if (ret == -ENXIO) uioinfo->irq = UIO_IRQ_NONE; else if (ret == -EPROBE_DEFER) return ret; -- 2.4.11

[PATCH 1/3] uio_pdrv_genirq: Remove warning when irq is not specified

Since e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no interrupt"), the uio_pdrv_genirq has supported use without interrupt, so the change in 7723f4c5ecdb ("driver core: platform: Add an error message to") added false warnings for those cases. Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()") Signed-off-by: Esben Haabendal <esben(a)geanix.com> Cc: stable(a)vger.kernel.org --- drivers/uio/uio_pdrv_genirq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/uio/uio_pdrv_genirq.c b/drivers/uio/uio_pdrv_genirq.c index ae319ef3a832..1d69dd49c6d2 100644 --- a/drivers/uio/uio_pdrv_genirq.c +++ b/drivers/uio/uio_pdrv_genirq.c @@ -159,7 +159,7 @@ static int uio_pdrv_genirq_probe(struct platform_device *pdev) priv->pdev = pdev; if (!uioinfo->irq) { - ret = platform_get_irq(pdev, 0); + ret = platform_get_irq_optional(pdev, 0); uioinfo->irq = ret; if (ret == -ENXIO && pdev->dev.of_node) uioinfo->irq = UIO_IRQ_NONE; -- 2.4.11

[PATCH 1/2] powerpc/mmu_gather: enable RCU_TABLE_FREE even for !SMP case

by Santosh Sivaraj

From: "Aneesh Kumar K.V" <aneesh.kumar(a)linux.ibm.com> commit 12e4d53f3f04e81f9e83d6fc10edc7314ab9f6b9 upstream The TLB flush optimisation (a46cc7a90f: powerpc/mm/radix: Improve TLB/PWC flushes) may result in random memory corruption. On any SMP system, freeing page directories should observe the exact same order as normal page freeing: 1) unhook page/directory 2) TLB invalidate 3) free page/directory Without this, any concurrent page-table walk could end up with a Use-after-Free. This is esp. trivial for anything that has software page-table walkers (HAVE_FAST_GUP / software TLB fill) or the hardware caches partial page-walks (ie. caches page directories). Even on UP this might give issues since mmu_gather is preemptible these days. An interrupt or preempted task accessing user pages might stumble into the free page if the hardware caches page directories. !SMP case is right now broken for radix translation w.r.t page walk cache flush. We can get interrupted in between page table free and that would imply we have page walk cache entries pointing to tables which got freed already. Michael said "both our platforms that run on Power9 force SMP on in Kconfig, so the !SMP case is unlikely to be a problem for anyone in practice, unless they've hacked their kernel to build it !SMP."

[PATCH 2/2] io_uring: use signal based task_work running

by Jens Axboe

Since 5.7, we've been using task_work to trigger async running of requests in the context of the original task. This generally works great, but there's a case where if the task is currently blocked in the kernel waiting on a condition to become true, it won't process task_work. Even though the task is woken, it just checks whatever condition it's waiting on, and goes back to sleep if it's still false. This is a problem if that very condition only becomes true when that task_work is run. An example of that is the task registering an eventfd with io_uring, and it's now blocked waiting on an eventfd read. That read could depend on a completion event, and that completion event won't get trigged until task_work has been run. Use the TWA_SIGNAL notification for task_work, so that we ensure that the task always runs the work when queued.

[PATCH 1/2] task_work: teach task_work_add() to do signal_wake_up()

by Jens Axboe

From: Oleg Nesterov <oleg(a)redhat.com> So that the target task will exit the wait_event_interruptible-like loop and call task_work_run() asap. The patch turns "bool notify" into 0,TWA_RESUME,TWA_SIGNAL enum, the new TWA_SIGNAL flag implies signal_wake_up(). However, it needs to avoid the race with recalc_sigpending(), so the patch also adds the new JOBCTL_TASK_WORK bit included in JOBCTL_PENDING_MASK. TODO: once this patch is merged we need to change all current users of task_work_add(notify = true) to use TWA_RESUME.

[PATCH] drm/i915: Skip stale object handle for debugfs per-file-stats

by Chris Wilson

As we close a handle GEM object, we update the drm_file's idr with an error pointer to indicate the in-progress closure, and finally set it to NULL. If we read the idr directly, we may then see an invalid object pointer, and in our debugfs per_file_stats() we therefore need to protect against the entry being invalid.

[PATCH] nvme: validate cntlid's only for nvme >= 1.1.0

by Maximilian Heyne

Controller ID's (cntlid) for NVMe devices were introduced in version 1.1.0 of the specification. Controllers that follow the older 1.0.0 spec don't set this field so it doesn't make sense to validate it. On the contrary, when using SR-IOV this check breaks VFs as they are all part of the same NVMe subsystem.

[PATCH v4] btrfs: pass checksum type via BTRFS_IOC_FS_INFO ioctl

by Johannes Thumshirn

With the recent addition of filesystem checksum types other than CRC32c, it is not anymore hard-coded which checksum type a btrfs filesystem uses. Up to now there is no good way to read the filesystem checksum, apart from reading the filesystem UUID and then query sysfs for the checksum type. Add a new csum_type and csum_size fields to the BTRFS_IOC_FS_INFO ioctl command which usually is used to query filesystem features. Also add a flags member indicating that the kernel responded with a set csum_type and csum_size field. For compatibility reasons, only return the csum_type and csum_size if the BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE flag was passed to the kernel. Also clear any unknown flags so we don't pass false positives to user-space newer than the kernel. To simplify further additions to the ioctl, also switch the padding to a u8 array. Pahole was used to verify the result of this switch: pahole -C btrfs_ioctl_fs_info_args fs/btrfs/btrfs.ko struct btrfs_ioctl_fs_info_args { __u64 max_id; /* 0 8 */ __u64 num_devices; /* 8 8 */ __u8 fsid[16]; /* 16 16 */ __u32 nodesize; /* 32 4 */ __u32 sectorsize; /* 36 4 */ __u32 clone_alignment; /* 40 4 */ __u32 flags; /* 44 4 */ __u16 csum_type; /* 48 2 */ __u16 csum_size; /* 50 2 */ __u8 reserved[972]; /* 52 972 */ /* size: 1024, cachelines: 16, members: 10 */ }; Fixes: 3951e7f050ac ("btrfs: add xxhash64 to checksumming algorithms") Fixes: 3831bf0094ab ("btrfs: add sha256 to checksumming algorithm") CC: stable(a)vger.kernel.org # 5.5+ Signed-off-by: Johannes Thumshirn <johannes.thumshirn(a)wdc.com> --- Changes to v3: * make flags in/out (David) * make csum return opt-in (Hans) Changes to v2: * add additional csum_size (David) * rename flag value to BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE to reflect additional size Changes to v1: * add 'out' comment to be consistent (Hans) * remove le16_to_cpu() (kbuild robot) * switch padding to be all u8 (David) --- fs/btrfs/ioctl.c | 16 +++++++++++++--- include/uapi/linux/btrfs.h | 14 ++++++++++++-- 2 files changed, 25 insertions(+), 5 deletions(-) diff --git a/fs/btrfs/ioctl.c b/fs/btrfs/ioctl.c index b3e4c632d80c..4d70b918f656 100644 --- a/fs/btrfs/ioctl.c +++ b/fs/btrfs/ioctl.c @@ -3198,11 +3198,15 @@ static long btrfs_ioctl_fs_info(struct btrfs_fs_info *fs_info, struct btrfs_ioctl_fs_info_args *fi_args; struct btrfs_device *device; struct btrfs_fs_devices *fs_devices = fs_info->fs_devices; + u32 inflags; int ret = 0; - fi_args = kzalloc(sizeof(*fi_args), GFP_KERNEL); - if (!fi_args) - return -ENOMEM; + fi_args = memdup_user(arg, sizeof(*fi_args)); + if (IS_ERR(fi_args)) + return PTR_ERR(fi_args); + + inflags = fi_args->flags; + fi_args->flags = 0; rcu_read_lock(); fi_args->num_devices = fs_devices->num_devices; @@ -3218,6 +3222,12 @@ static long btrfs_ioctl_fs_info(struct btrfs_fs_info *fs_info, fi_args->sectorsize = fs_info->sectorsize; fi_args->clone_alignment = fs_info->sectorsize; + if (inflags & BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE) { + fi_args->csum_type = btrfs_super_csum_type(fs_info->super_copy); + fi_args->csum_size = btrfs_super_csum_size(fs_info->super_copy); + fi_args->flags |= BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE; + } + if (copy_to_user(arg, fi_args, sizeof(*fi_args))) ret = -EFAULT; diff --git a/include/uapi/linux/btrfs.h b/include/uapi/linux/btrfs.h index e6b6cb0f8bc6..c130eaea416e 100644 --- a/include/uapi/linux/btrfs.h +++ b/include/uapi/linux/btrfs.h @@ -250,10 +250,20 @@ struct btrfs_ioctl_fs_info_args { __u32 nodesize; /* out */ __u32 sectorsize; /* out */ __u32 clone_alignment; /* out */ - __u32 reserved32; - __u64 reserved[122]; /* pad to 1k */ + __u32 flags; /* in/out */ + __u16 csum_type; /* out */ + __u16 csum_size; /* out */ + __u8 reserved[972]; /* pad to 1k */ }; +/* + * fs_info ioctl flags + * + * Used by: + * struct btrfs_ioctl_fs_info_args + */ +#define BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE (1 << 0) + /* * feature flags * -- 2.26.2

[tip: x86/urgent] x86/split_lock: Don't write MSR_TEST_CTRL on CPUs that aren't whitelisted

by tip-bot2 for Sean Christopherson

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 009bce1df0bb5eb970b9eb98d963861f7fe353c7 Gitweb: https://git.kernel.org/tip/009bce1df0bb5eb970b9eb98d963861f7fe353c7 Author: Sean Christopherson <sean.j.christopherson(a)intel.com> AuthorDate: Fri, 05 Jun 2020 12:26:05 -07:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Tue, 30 Jun 2020 14:09:31 +02:00 x86/split_lock: Don't write MSR_TEST_CTRL on CPUs that aren't whitelisted Choo! Choo! All aboard the Split Lock Express, with direct service to Wreckage! Skip split_lock_verify_msr() if the CPU isn't whitelisted as a possible SLD-enabled CPU model to avoid writing MSR_TEST_CTRL. MSR_TEST_CTRL exists, and is writable, on many generations of CPUs. Writing the MSR, even with '0', can result in bizarre, undocumented behavior. This fixes a crash on Haswell when resuming from suspend with a live KVM guest. Because APs use the standard SMP boot flow for resume, they will go through split_lock_init() and the subsequent RDMSR/WRMSR sequence, which runs even when sld_state==sld_off to ensure SLD is disabled. On Haswell (at least, my Haswell), writing MSR_TEST_CTRL with '0' will succeed and _may_ take the SMT _sibling_ out of VMX root mode. When KVM has an active guest, KVM performs VMXON as part of CPU onlining (see kvm_starting_cpu()). Because SMP boot is serialized, the resulting flow is effectively: on_each_ap_cpu() { WRMSR(MSR_TEST_CTRL, 0) VMXON } As a result, the WRMSR can disable VMX on a different CPU that has already done VMXON. This ultimately results in a #UD on VMPTRLD when KVM regains control and attempt run its vCPUs. The above voodoo was confirmed by reworking KVM's VMXON flow to write MSR_TEST_CTRL prior to VMXON, and to serialize the sequence as above. Further verification of the insanity was done by redoing VMXON on all APs after the initial WRMSR->VMXON sequence. The additional VMXON, which should VM-Fail, occasionally succeeded, and also eliminated the unexpected #UD on VMPTRLD. The damage done by writing MSR_TEST_CTRL doesn't appear to be limited to VMX, e.g. after suspend with an active KVM guest, subsequent reboots almost always hang (even when fudging VMXON), a #UD on a random Jcc was observed, suspend/resume stability is qualitatively poor, and so on and so forth. kernel BUG at arch/x86/kvm/x86.c:386!

[PATCH 08/10] mfd: atmel-smc: Silence comparison of unsigned expression < 0 is always false warning (W=1)

by Lee Jones

GENMASK and it's callees conduct checking to ensure the passed parameters are valid. One of those checks is for '< 0'. So if an unsigned value is passed, in an invalid comparison takes place. Judging from the current code, it looks as though 'unsigned int' is the correct type to use, so simply cast these small values with no chance of being false negative to signed int for comparison/error checking purposes.

[PATCH] KVM: x86: bit 8 of non-leaf PDPEs is not reserved

by Paolo Bonzini

Bit 8 would be the "global" bit, which does not quite make sense for non-leaf page table entries. Intel ignores it; AMD ignores it in PDEs and PDPEs, but reserves it in PML4Es. Probably, earlier versions of the AMD manual documented it as reserved in PDPEs as well, and that behavior made it into KVM as well as kvm-unit-tests; fix it.

But these sequences only expand into anything meaningful if the BL_SWITCHER option is selected, which almost never happens. It also turns out that using a RMW and locks is just as silly, as the GIC distributor supports byte accesses for the GICD_TARGETRn registers, which when used make the update atomic by definition. Drop the terminally broken code and replace it by a byte write.

With the recent addition of filesystem checksum types other than CRC32c, it is not anymore hard-coded which checksum type a btrfs filesystem uses. Up to now there is no good way to read the filesystem checksum, apart from reading the filesystem UUID and then query sysfs for the checksum type. Add a new csum_type field to the BTRFS_IOC_FS_INFO ioctl command which usually is used to query filesystem features. Also add a flags member indicating that the kernel responded with a set csum_type field. To simplify further additions to the ioctl, also switch the padding to a u8 array. Pahole was used to verify the result of this switch: pahole -C btrfs_ioctl_fs_info_args fs/btrfs/btrfs.ko struct btrfs_ioctl_fs_info_args { __u64 max_id; /* 0 8 */ __u64 num_devices; /* 8 8 */ __u8 fsid[16]; /* 16 16 */ __u32 nodesize; /* 32 4 */ __u32 sectorsize; /* 36 4 */ __u32 clone_alignment; /* 40 4 */ __u32 flags; /* 44 4 */ __u16 csum_type; /* 48 2 */ __u16 csum_size; /* 50 2 */ __u8 reserved[972]; /* 52 972 */ /* size: 1024, cachelines: 16, members: 10 */ }; Fixes: 3951e7f050ac ("btrfs: add xxhash64 to checksumming algorithms") Fixes: 3831bf0094ab ("btrfs: add sha256 to checksumming algorithm") Cc: stable(a)vger.kernel.org Signed-off-by: Johannes Thumshirn <johannes.thumshirn(a)wdc.com> --- Changes to v2: * add additional csum_size (David) * rename flag value to BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE to reflect additional size Changes to v1: * add 'out' comment to be consistent (Hans) * remove le16_to_cpu() (kbuild robot) * switch padding to be all u8 (David) --- fs/btrfs/ioctl.c | 3 +++ include/uapi/linux/btrfs.h | 14 ++++++++++++-- 2 files changed, 15 insertions(+), 2 deletions(-) diff --git a/fs/btrfs/ioctl.c b/fs/btrfs/ioctl.c index b3e4c632d80c..cfedcdf446c3 100644 --- a/fs/btrfs/ioctl.c +++ b/fs/btrfs/ioctl.c @@ -3217,6 +3217,9 @@ static long btrfs_ioctl_fs_info(struct btrfs_fs_info *fs_info, fi_args->nodesize = fs_info->nodesize; fi_args->sectorsize = fs_info->sectorsize; fi_args->clone_alignment = fs_info->sectorsize; + fi_args->csum_type = btrfs_super_csum_type(fs_info->super_copy); + fi_args->csum_size = btrfs_super_csum_size(fs_info->super_copy); + fi_args->flags |= BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE; if (copy_to_user(arg, fi_args, sizeof(*fi_args))) ret = -EFAULT; diff --git a/include/uapi/linux/btrfs.h b/include/uapi/linux/btrfs.h index e6b6cb0f8bc6..2de3ef3c5c71 100644 --- a/include/uapi/linux/btrfs.h +++ b/include/uapi/linux/btrfs.h @@ -250,10 +250,20 @@ struct btrfs_ioctl_fs_info_args { __u32 nodesize; /* out */ __u32 sectorsize; /* out */ __u32 clone_alignment; /* out */ - __u32 reserved32; - __u64 reserved[122]; /* pad to 1k */ + __u32 flags; /* out */ + __u16 csum_type; /* out */ + __u16 csum_size; /* out */ + __u8 reserved[972]; /* pad to 1k */ }; +/* + * fs_info ioctl flags + * + * Used by: + * struct btrfs_ioctl_fs_info_args + */ +#define BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE (1 << 0) + /* * feature flags * -- 2.26.2

External kmod build failed on KASAN-enabled kernel

Hi, The same kmod source code can be built on KASAN-disabled kernel (5.7.0), but after enable it with CONFIG_KASAN=y, the kmod can't build on the new installed KASAN-enabled kernel with below error message, seems no relevant answers for this issue with google: root@build-ws:/home/mm/slab# make make -C /lib/modules/5.7.0/build M=/home/mm/slab modules make[1]: Entering directory '/home/linux-5.7' CC [M] /home/mm/slab/tap_slab.o MODPOST 1 modules ERROR: modpost: "__asan_register_globals" [/home/mm/slab/tap_slab.ko] undefined!

For commits that only have a "Fixes:" tag, and not a "cc: stable..." tag, wait a few weeks, or a month, for us to catch up with them. We usually get to them eventually, but it takes us a while as we have lots more to deal with by developers and maintainers that are properly tagging patches for this type of thing. Some of the above commits are queued up already, but not all of them. I'll take a look at the list after this next round of patches go out, and will let you know. And yes, we do want this type of list, it's greatly appreciated. thanks, greg k-h

[PATCH 1/1] usb: chipidea: core: add wakeup support for extcon

by Peter Chen

If wakeup event occurred by extcon event, it needs to call ci_irq again since the first ci_irq calling at extcon notifier only wakes up controller, but do noop for event handling, it causes the extcon use case can't work well from low power mode.

But, I think that it is not necessary fully kernel panic log about NULL pointer. It is enoughspsp just mentioning the NULL pointer issue without full kernel panic log. So, how about editing the patch description as following or others simply? and we need to add 'stable(a)vger.kernel.org' to Cc list for applying it to stable branch. PM / devfreq: rk3399_dmc: Fix kernel oops when rockchip,pmu is absent Booting a recent kernel on a rk3399-based system (nanopc-t4), equipped with a recent u-boot and ATF results in the kernel panic about NULL pointer issue. This turns out to be due to the rk3399-dmc driver looking for an *undocumented* property (rockchip,pmu), and happily using a NULL pointer when the property isn't there. Instead, make most of what was brought in with 9173c5ceb035 ("PM / devfreq: rk3399_dmc: Pass ODT and auto power down parameters to TF-A.") conditioned on finding this property in the device-tree, preventing the driver from exploding. Fixes: 9173c5ceb035 ("PM / devfreq: rk3399_dmc: Pass ODT and auto power down parameters to TF-A.")

[PATCH] clk: sifive: allocate sufficient memory for struct __prci_data

by Vincent Chen

The (struct __prci_data).hw_clks.hws is an array with dynamic elements. Using struct_size(pd, hw_clks.hws, ARRAY_SIZE(__prci_init_clocks)) instead of sizeof(*pd) to get the correct memory size of struct __prci_data for sifive/fu540-prci. After applying this modifications, the kernel runs smoothly with CONFIG_SLAB_FREELIST_RANDOM enabled on the HiFive unleashed board.

Upstream fixes not merged in 5.4.y

by SeongJae Park

Hello, With my little script, I found below commits in the mainline tree are more than 1 week old and fixing commits that back-ported in v5.4..v5.4.49 but not merged in the stable/linux-5.4.y tree. Are those need to be merged in but missed or dealyed? 9210c075cef2 ("nvme-pci: avoid race between nvme_reap_pending_cqes() and nvme_poll()") 9fecd13202f5 ("btrfs: fix a block group ref counter leak after failure to remove block group") 9d964e1b82d8 ("fix a braino in "sparc32: fix register window handling in genregs32_[gs]et()"") 8ab3a3812aa9 ("drm/i915/gt: Incrementally check for rewinding") 6e2f83884c09 ("bnxt_en: Fix AER reset logic on 57500 chips.") efb94790852a ("drm/panel-simple: fix connector type for LogicPD Type28 Display") ff58bbc7b970 ("ALSA: usb-audio: Fix potential use-after-free of streams") ff58bbc7b970 ("ALSA: usb-audio: Fix potential use-after-free of streams") 8dbe4c5d5e40 ("net: dsa: bcm_sf2: Fix node reference count") ca8826095e4d ("selftests/net: report etf errors correctly") 5a8d7f126c97 ("of: of_mdio: Correct loop scanning logic") d35d3660e065 ("binder: fix null deref of proc->context") The script found several more commits but I exclude those here, because those seems not applicable on 5.4.y or fixing trivial problems only. If I'm not following a proper process for this kind of reports, please let me know. Thanks, SeongJae Park

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.

patch "mei: bus: don't clean driver pointer" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled mei: bus: don't clean driver pointer to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From e852c2c251ed9c23ae6e3efebc5ec49adb504207 Mon Sep 17 00:00:00 2001 From: Alexander Usyskin <alexander.usyskin(a)intel.com> Date: Mon, 29 Jun 2020 01:53:59 +0300 Subject: mei: bus: don't clean driver pointer It's not needed to set driver to NULL in mei_cl_device_remove() which is bus_type remove() handler as this is done anyway in __device_release_driver(). Actually this is causing an endless loop in driver_detach() on ubuntu patched kernel, while removing (rmmod) the mei_hdcp module. The reason list_empty(&drv->p->klist_devices.k_list) is always not-empty. as the check is always true in __device_release_driver() if (dev->driver != drv) return; The non upstream patch is causing this behavior, titled: 'vfio -- release device lock before userspace requests' Nevertheless the fix is correct also for the upstream.

[PATCH 2/4] KVM: arm64: Fix kvm_reset_vcpu() return code being incorrect with SVE

by Marc Zyngier

From: Steven Price <steven.price(a)arm.com> If SVE is enabled then 'ret' can be assigned the return value of kvm_vcpu_enable_sve() which may be 0 causing future "goto out" sites to erroneously return 0 on failure rather than -EINVAL as expected. Remove the initialisation of 'ret' and make setting the return value explicit to avoid this situation in the future.

[PATCH 1/4] KVM: arm64: Annotate hyp NMI-related functions as __always_inline

by Marc Zyngier

From: Alexandru Elisei <alexandru.elisei(a)arm.com> The "inline" keyword is a hint for the compiler to inline a function. The functions system_uses_irq_prio_masking() and gic_write_pmr() are used by the code running at EL2 on a non-VHE system, so mark them as __always_inline to make sure they'll always be part of the .hyp.text section.

On xfs it fails, as expected, but on ext4 it currently succeeds because apparently it is expensive to check if there are extents allocated for the whole range, but I'll check with the ext4 people.

These preallocated extents have, and must have, the same size that extents from the data block group being relocated have. Later before we start the relocation stage that updates pointers (bytenr field of file extent items) to point to the the new extents, we trigger writeback for the data relocation inode. The expectation is that writeback will write the pages to the previously preallocated extents, that it follows the NOCOW path. That is generally the case, however, if a scrub is running it may have turned the block group that contains those extents into RO mode, in which case writeback falls back to the COW path. However in the COW path instead of allocating exactly one extent with the expected size, the allocator may end up allocating several smaller extents due to free space fragmentation - because we tell it at cow_file_range() that the minimum allocation size can match the filesystem's sector size. This later breaks the relocation's expectation that an extent associated to a file extent item in the data relocation inode has the same size as the respective extent pointed by a file extent item in another tree - in this case the extent to which the relocation inode poins to is smaller, causing relocation.c:get_new_location() to return -EINVAL. For example, if we are relocating a data block group X that has a logical address of X and the block group has an extent allocated at the logical address X + 128KiB with a size of 64KiB: 1) At prealloc_file_extent_cluster() we allocate an extent for the data relocation inode with a size of 64KiB and associate it to the file offset 128KiB (X + 128KiB - X) of the data relocation inode. This preallocated extent was allocated at block group Z; 2) A scrub running in parallel turns block group Z into RO mode and starts scrubing its extents; 3) Relocation triggers writeback for the data relocation inode; 4) When running delalloc (btrfs_run_delalloc_range()), we try first the NOCOW path because the data relocation inode has BTRFS_INODE_PREALLOC set in its flags. However, because block group Z is in RO mode, the NOCOW path (run_delalloc_nocow()) falls back into the COW path, by calling cow_file_range(); 5) At cow_file_range(), in the first iteration of the while loop we call btrfs_reserve_extent() to allocate a 64KiB extent and pass it a minimum allocation size of 4KiB (fs_info->sectorsize). Due to free space fragmentation, btrfs_reserve_extent() ends up allocating two extents of 32KiB each, each one on a different iteration of that while loop; 6) Writeback of the data relocation inode completes; 7) Relocation proceeds and ends up at relocation.c:replace_file_extents(), with a leaf which has a file extent item that points to the data extent from block group X, that has a logical address (bytenr) of X + 128KiB and a size of 64KiB. Then it calls get_new_location(), which does a lookup in the data relocation tree for a file extent item starting at offset 128KiB (X + 128KiB - X) and belonging to the data relocation inode. It finds a corresponding file extent item, however that item points to an extent that has a size of 32KiB, which doesn't match the expected size of 64KiB, resuling in -EINVAL being returned from this function and propagated up to __btrfs_cow_block(), which aborts the current transaction. To fix this make sure that at cow_file_range() when we call the allocator we pass it a minimum allocation size corresponding the desired extent size if the inode belongs to the data relocation tree, otherwise pass it the filesystem's sector size as the minimum allocation size.

These preallocated extents have, and must have, the same size that extents from the data block group being relocated have. Later before we start the relocation stage that updates pointers (bytenr field of file extent items) to point to the the new extents, we trigger writeback for the data relocation inode. The expectation is that writeback will write the pages to the previously preallocated extents, that it follows the NOCOW path. That is generally the case, however, if a scrub is running it may have turned the block group that contains those extents into RO mode, in which case writeback falls back to the COW path. However in the COW path instead of allocating exactly one extent with the expected size, the allocator may end up allocating several smaller extents due to free space fragmentation - because we tell it at cow_file_range() that the minimum allocation size can match the filesystem's sector size. This later breaks the relocation's expectation that an extent associated to a file extent item in the data relocation inode has the same size as the respective extent pointed by a file extent item in another tree - in this case the extent to which the relocation inode poins to is smaller, causing relocation.c:get_new_location() to return -EINVAL. For example, if we are relocating a data block group X that has a logical address of X and the block group has an extent allocated at the logical address X + 128KiB with a size of 64KiB: 1) At prealloc_file_extent_cluster() we allocate an extent for the data relocation inode with a size of 64KiB and associate it to the file offset 128KiB (X + 128KiB - X) of the data relocation inode. This preallocated extent was allocated at block group Z; 2) A scrub running in parallel turns block group Z into RO mode and starts scrubing its extents; 3) Relocation triggers writeback for the data relocation inode; 4) When running delalloc (btrfs_run_delalloc_range()), we try first the NOCOW path because the data relocation inode has BTRFS_INODE_PREALLOC set in its flags. However, because block group Z is in RO mode, the NOCOW path (run_delalloc_nocow()) falls back into the COW path, by calling cow_file_range(); 5) At cow_file_range(), in the first iteration of the while loop we call btrfs_reserve_extent() to allocate a 64KiB extent and pass it a minimum allocation size of 4KiB (fs_info->sectorsize). Due to free space fragmentation, btrfs_reserve_extent() ends up allocating two extents of 32KiB each, each one on a different iteration of that while loop; 6) Writeback of the data relocation inode completes; 7) Relocation proceeds and ends up at relocation.c:replace_file_extents(), with a leaf which has a file extent item that points to the data extent from block group X, that has a logical address (bytenr) of X + 128KiB and a size of 64KiB. Then it calls get_new_location(), which does a lookup in the data relocation tree for a file extent item starting at offset 128KiB (X + 128KiB - X) and belonging to the data relocation inode. It finds a corresponding file extent item, however that item points to an extent that has a size of 32KiB, which doesn't match the expected size of 64KiB, resuling in -EINVAL being returned from this function and propagated up to __btrfs_cow_block(), which aborts the current transaction. To fix this make sure that at cow_file_range() when we call the allocator we pass it a minimum allocation size corresponding the desired extent size if the inode belongs to the data relocation tree, otherwise pass it the filesystem's sector size as the minimum allocation size.

FAILED: patch "[PATCH] btrfs: fix race between block group removal and block group" failed to apply to 4.9-stable tree

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From ffcb9d44572afbaf8fa6dbf5115bff6dab7b299e Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Mon, 1 Jun 2020 19:12:19 +0100 Subject: [PATCH] btrfs: fix race between block group removal and block group creation There is a race between block group removal and block group creation when the removal is completed by a task running fitrim or scrub. When this happens we end up failing the block group creation with an error -EEXIST since we attempt to insert a duplicate block group item key in the extent tree. That results in a transaction abort. The race happens like this: 1) Task A is doing a fitrim, and at btrfs_trim_block_group() it freezes block group X with btrfs_freeze_block_group() (until very recently that was named btrfs_get_block_group_trimming()); 2) Task B starts removing block group X, either because it's now unused or due to relocation for example. So at btrfs_remove_block_group(), while holding the chunk mutex and the block group's lock, it sets the 'removed' flag of the block group and it sets the local variable 'remove_em' to false, because the block group is currently frozen (its 'frozen' counter is > 0, until very recently this counter was named 'trimming'); 3) Task B unlocks the block group and the chunk mutex; 4) Task A is done trimming the block group and unfreezes the block group by calling btrfs_unfreeze_block_group() (until very recently this was named btrfs_put_block_group_trimming()). In this function we lock the block group and set the local variable 'cleanup' to true because we were able to decrement the block group's 'frozen' counter down to 0 and the flag 'removed' is set in the block group. Since 'cleanup' is set to true, it locks the chunk mutex and removes the extent mapping representing the block group from the mapping tree; 5) Task C allocates a new block group Y and it picks up the logical address that block group X had as the logical address for Y, because X was the block group with the highest logical address and now the second block group with the highest logical address, the last in the fs mapping tree, ends at an offset corresponding to block group X's logical address (this logical address selection is done at volumes.c:find_next_chunk()). At this point the new block group Y does not have yet its item added to the extent tree (nor the corresponding device extent items and chunk item in the device and chunk trees). The new group Y is added to the list of pending block groups in the transaction handle; 6) Before task B proceeds to removing the block group item for block group X from the extent tree, which has a key matching: (X logical offset, BTRFS_BLOCK_GROUP_ITEM_KEY, length) task C while ending its transaction handle calls btrfs_create_pending_block_groups(), which finds block group Y and tries to insert the block group item for Y into the exten tree, which fails with -EEXIST since logical offset is the same that X had and task B hasn't yet deleted the key from the extent tree. This failure results in a transaction abort, producing a stack like the following: ------------[ cut here ]------------ BTRFS: Transaction aborted (error -17) WARNING: CPU: 2 PID: 19736 at fs/btrfs/block-group.c:2074 btrfs_create_pending_block_groups+0x1eb/0x260 [btrfs] Modules linked in: btrfs blake2b_generic xor raid6_pq (...)

In this function we lock the block group and set the local variable 'cleanup' to true because we were able to decrement the block group's 'frozen' counter down to 0 and the flag 'removed' is set in the block group. Since 'cleanup' is set to true, it locks the chunk mutex and removes the extent mapping representing the block group from the mapping tree; 5) Task C allocates a new block group Y and it picks up the logical address that block group X had as the logical address for Y, because X was the block group with the highest logical address and now the second block group with the highest logical address, the last in the fs mapping tree, ends at an offset corresponding to block group X's logical address (this logical address selection is done at volumes.c:find_next_chunk()). At this point the new block group Y does not have yet its item added to the extent tree (nor the corresponding device extent items and chunk item in the device and chunk trees). The new group Y is added to the list of pending block groups in the transaction handle; 6) Before task B proceeds to removing the block group item for block group X from the extent tree, which has a key matching: (X logical offset, BTRFS_BLOCK_GROUP_ITEM_KEY, length) task C while ending its transaction handle calls btrfs_create_pending_block_groups(), which finds block group Y and tries to insert the block group item for Y into the exten tree, which fails with -EEXIST since logical offset is the same that X had and task B hasn't yet deleted the key from the extent tree. This failure results in a transaction abort, producing a stack like the following: ------------[ cut here ]------------ BTRFS: Transaction aborted (error -17) WARNING: CPU: 2 PID: 19736 at fs/btrfs/block-group.c:2074 btrfs_create_pending_block_groups+0x1eb/0x260 [btrfs] Modules linked in: btrfs blake2b_generic xor raid6_pq (...)

FAILED: patch "[PATCH] btrfs: fix race between block group removal and block group" failed to apply to 5.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From ffcb9d44572afbaf8fa6dbf5115bff6dab7b299e Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Mon, 1 Jun 2020 19:12:19 +0100 Subject: [PATCH] btrfs: fix race between block group removal and block group creation There is a race between block group removal and block group creation when the removal is completed by a task running fitrim or scrub. When this happens we end up failing the block group creation with an error -EEXIST since we attempt to insert a duplicate block group item key in the extent tree. That results in a transaction abort. The race happens like this: 1) Task A is doing a fitrim, and at btrfs_trim_block_group() it freezes block group X with btrfs_freeze_block_group() (until very recently that was named btrfs_get_block_group_trimming()); 2) Task B starts removing block group X, either because it's now unused or due to relocation for example. So at btrfs_remove_block_group(), while holding the chunk mutex and the block group's lock, it sets the 'removed' flag of the block group and it sets the local variable 'remove_em' to false, because the block group is currently frozen (its 'frozen' counter is > 0, until very recently this counter was named 'trimming'); 3) Task B unlocks the block group and the chunk mutex; 4) Task A is done trimming the block group and unfreezes the block group by calling btrfs_unfreeze_block_group() (until very recently this was named btrfs_put_block_group_trimming()). In this function we lock the block group and set the local variable 'cleanup' to true because we were able to decrement the block group's 'frozen' counter down to 0 and the flag 'removed' is set in the block group. Since 'cleanup' is set to true, it locks the chunk mutex and removes the extent mapping representing the block group from the mapping tree; 5) Task C allocates a new block group Y and it picks up the logical address that block group X had as the logical address for Y, because X was the block group with the highest logical address and now the second block group with the highest logical address, the last in the fs mapping tree, ends at an offset corresponding to block group X's logical address (this logical address selection is done at volumes.c:find_next_chunk()). At this point the new block group Y does not have yet its item added to the extent tree (nor the corresponding device extent items and chunk item in the device and chunk trees). The new group Y is added to the list of pending block groups in the transaction handle; 6) Before task B proceeds to removing the block group item for block group X from the extent tree, which has a key matching: (X logical offset, BTRFS_BLOCK_GROUP_ITEM_KEY, length) task C while ending its transaction handle calls btrfs_create_pending_block_groups(), which finds block group Y and tries to insert the block group item for Y into the exten tree, which fails with -EEXIST since logical offset is the same that X had and task B hasn't yet deleted the key from the extent tree. This failure results in a transaction abort, producing a stack like the following: ------------[ cut here ]------------ BTRFS: Transaction aborted (error -17) WARNING: CPU: 2 PID: 19736 at fs/btrfs/block-group.c:2074 btrfs_create_pending_block_groups+0x1eb/0x260 [btrfs] Modules linked in: btrfs blake2b_generic xor raid6_pq (...)

We reserve space by calling btrfs_check_data_free_space(), which ends up incrementing the data space_info's bytes_may_use counter, and then call btrfs_prealloc_file_range() to allocate the extent, which always decrements the bytes_may_use counter by the same amount. The expectation is that writeback of the data relocation inode always follows a NOCOW path, by writing into the preallocated extents. However, when starting writeback we might end up falling back into the COW path, because the block group that contains the preallocated extent was turned into RO mode by a scrub running in parallel. The COW path then calls the extent allocator which ends up calling btrfs_add_reserved_bytes(), and this function decrements the bytes_may_use counter of the data space_info object by an amount corresponding to the size of the allocated extent, despite we haven't previously incremented it. When the counter currently has a value smaller then the allocated extent we reset the counter to 0 and emit a warning, otherwise we just decrement it and slowly mess up with this counter which is crucial for space reservation, the end result can be granting reserved space to tasks when there isn't really enough free space, and having the tasks fail later in critical places where error handling consists of a transaction abort or hitting a BUG_ON(). Fix this by making sure that if we fallback to the COW path for a data relocation inode, we increment the bytes_may_use counter of the data space_info object. The COW path will then decrement it at btrfs_add_reserved_bytes() on success or through its error handling part by a call to extent_clear_unlock_delalloc() (which ends up calling btrfs_clear_delalloc_extent() that does the decrement operation) in case of an error. Test case btrfs/061 from fstests could sporadically trigger this.

We reserve space by calling btrfs_check_data_free_space(), which ends up incrementing the data space_info's bytes_may_use counter, and then call btrfs_prealloc_file_range() to allocate the extent, which always decrements the bytes_may_use counter by the same amount. The expectation is that writeback of the data relocation inode always follows a NOCOW path, by writing into the preallocated extents. However, when starting writeback we might end up falling back into the COW path, because the block group that contains the preallocated extent was turned into RO mode by a scrub running in parallel. The COW path then calls the extent allocator which ends up calling btrfs_add_reserved_bytes(), and this function decrements the bytes_may_use counter of the data space_info object by an amount corresponding to the size of the allocated extent, despite we haven't previously incremented it. When the counter currently has a value smaller then the allocated extent we reset the counter to 0 and emit a warning, otherwise we just decrement it and slowly mess up with this counter which is crucial for space reservation, the end result can be granting reserved space to tasks when there isn't really enough free space, and having the tasks fail later in critical places where error handling consists of a transaction abort or hitting a BUG_ON(). Fix this by making sure that if we fallback to the COW path for a data relocation inode, we increment the bytes_may_use counter of the data space_info object. The COW path will then decrement it at btrfs_add_reserved_bytes() on success or through its error handling part by a call to extent_clear_unlock_delalloc() (which ends up calling btrfs_clear_delalloc_extent() that does the decrement operation) in case of an error. Test case btrfs/061 from fstests could sporadically trigger this.

To make things less error prone, decrement the reference count for the rbtree immediately after removing the block group from it. This also eleminates the need for two different exit labels on error, renaming 'out_put_label' to just 'out' and removing the old 'out'.

[PATCH 4.19.y] erofs: fix partially uninitialized misuse in z_erofs_onlinepage_fixup

by Gao Xiang

From: Gao Xiang <hsiangkao(a)redhat.com> commit 3c597282887fd55181578996dca52ce697d985a5 upstream. Hongyu reported "id != index" in z_erofs_onlinepage_fixup() with specific aarch64 environment easily, which wasn't shown before. After digging into that, I found that high 32 bits of page->private was set to 0xaaaaaaaa rather than 0 (due to z_erofs_onlinepage_init behavior with specific compiler options). Actually we only use low 32 bits to keep the page information since page->private is only 4 bytes on most 32-bit platforms. However z_erofs_onlinepage_fixup() uses the upper 32 bits by mistake. Let's fix it now.

[char-misc-next] mei: bus: don't clean driver pointer

by Tomas Winkler

From: Alexander Usyskin <alexander.usyskin(a)intel.com> It's not needed to set driver to NULL in mei_cl_device_remove() which is bus_type remove() handler as this is done anyway in __device_release_driver(). Actually this is causing an endless loop in driver_detach() on ubuntu patched kernel, while removing (rmmod) the mei_hdcp module. The reason list_empty(&drv->p->klist_devices.k_list) is always not-empty. as the check is always true in __device_release_driver() if (dev->driver != drv) return; The non upstream patch is causing this behavior, titled: 'vfio -- release device lock before userspace requests' Nevertheless the fix is correct also for the upstream.

[PATCH v2] nouveau: fix page fault on device private memory

by Ralph Campbell

If system memory is migrated to device private memory and no GPU MMU page table entry exists, the GPU will fault and call hmm_range_fault() to get the PFN for the page. Since the .dev_private_owner pointer in struct hmm_range is not set, hmm_range_fault returns an error which results in the GPU program stopping with a fatal fault. Fix this by setting .dev_private_owner appropriately. Fixes: 08ddddda667b ("mm/hmm: check the device private page owner in hmm_range_fault()") Cc: stable(a)vger.kernel.org Signed-off-by: Ralph Campbell <rcampbell(a)nvidia.com> Reviewed-by: Jason Gunthorpe <jgg(a)mellanox.com> --- This is based on Linux-5.8.0-rc2 and is for Ben Skeggs nouveau tree.

However, from the log above we can see that the usb 1-7 doesn't get bus suspended due to not in U0. After a while the port finished U2 -> U0 transition, interrupts the suspend process. The observation is that after disabling LPM, port doesn't transit to U0 immediately and can linger in U2. xHCI spec 4.23.5.2 states that the maximum exit latency for USB2 LPM should be BESL + 10us. The BESL for the affected device is advertised as 400us, which is still not enough based on my testing result. So let's use the maximum permitted latency, 10000, to poll for U0 status to solve the issue.

A few of them (snd_usb_mixer_notify_id() and snd_usb_mixer_interrupt_v2()) assume each mixer element being a usb_mixer_elem_info object that is a subclass of usb_mixer_elem_list, cast via container_of() and access it members. This may result in an out-of-bound access when a non-standard list element has been added, as spotted by syzkaller recently. This patch adds a new field, is_std_info, in usb_mixer_elem_list to indicate that the element is the usb_mixer_elem_info type or not, and skip the access to such an element if needed.

[PATCH 2/6] ASoC: rt5670: Correct RT5670_LDO_SEL_MASK

by Hans de Goede

The RT5670_PWR_ANLG1 register has 3 bits to select the LDO voltage, so the correct mask is 0x7 not 0x3. Because of this wrong mask we were programming the ldo bits to a setting of binary 001 (0x05 & 0x03) instead of binary 101 when moving to SND_SOC_BIAS_PREPARE. According to the datasheet 001 is a reserved value, so no idea what it did, since the driver was working fine before I guess we got lucky and it does something which is ok.

[PATCH 2/6] ASoC: rt5670: Correct RT5670_LDO_SEL_MASK

by Hans de Goede

The RT5670_PWR_ANLG1 register has 3 bits to select the LDO voltage, so the correct mask is 0x7 not 0x3. Because of this wrong mask we were programming the ldo bits to a setting of binary 001 (0x05 & 0x03) instead of binary 101 when moving to SND_SOC_BIAS_PREPARE. According to the datasheet 001 is a reserved value, so no idea what it did, since the driver was working fine before I guess we got lucky and it does something which is ok.

[PATCH 3/6] fs/minix: reject too-large maximum file size

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> If the minix filesystem tries to map a very large logical block number to its on-disk location, block_to_path() can return offsets that are too large, causing out-of-bounds memory accesses when accessing indirect index blocks. This should be prevented by the check against the maximum file size, but this doesn't work because the maximum file size is read directly from the on-disk superblock and isn't validated itself. Fix this by validating the maximum file size at mount time.

patch "Revert "serial: core: Refactor uart_unlock_and_check_sysrq()"" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled Revert "serial: core: Refactor uart_unlock_and_check_sysrq()" to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 10652a9e9fe3fbcaca090f99cd3060ac3fee2913 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Wed, 10 Jun 2020 17:22:30 +0200 Subject: Revert "serial: core: Refactor uart_unlock_and_check_sysrq()" This reverts commit da9a5aa3402db0ff3b57216d8dbf2478e1046cae. In order to ease backporting a fix for a sysrq regression, revert this rewrite which was since added on top. The other sysrq helpers now bail out early when sysrq is not enabled; it's better to keep that pattern here as well. Note that the __releases() attribute won't be needed after the follow-on fix either.

[merged] mm-fix-false-softlockup-during-pfn-range-removal.patch removed from -mm tree

by Andrew Morton

The patch titled Subject: mm/memory_hotplug.c: fix false softlockup during pfn range removal has been removed from the -mm tree. Its filename was mm-fix-false-softlockup-during-pfn-range-removal.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Ben Widawsky <ben.widawsky(a)intel.com> Subject: mm/memory_hotplug.c: fix false softlockup during pfn range removal When working with very large nodes, poisoning the struct pages (for which there will be very many) can take a very long time. If the system is using voluntary preemptions, the software watchdog will not be able to detect forward progress. This patch addresses this issue by offering to give up time like __remove_pages() does. This behavior was introduced in v5.6 with: commit d33695b16a9f ("mm/memory_hotplug: poison memmap in remove_pfn_range_from_zone()") Alternately, init_page_poison could do this cond_resched(), but it seems to me that the caller of init_page_poison() is what actually knows whether or not it should relax its own priority. Based on Dan's notes, I think this is perfectly safe: commit f931ab479dd2 ("mm: fix devm_memremap_pages crash, use mem_hotplug_{begin, done}") Aside from fixing the lockup, it is also a friendlier thing to do on lower core systems that might wipe out large chunks of hotplug memory (probably not a very common case).

[merged] mm-slab-use-memzero_explicit-in-kzfree.patch removed from -mm tree

by Andrew Morton

The patch titled Subject: mm/slab: use memzero_explicit() in kzfree() has been removed from the -mm tree. Its filename was mm-slab-use-memzero_explicit-in-kzfree.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Waiman Long <longman(a)redhat.com> Subject: mm/slab: use memzero_explicit() in kzfree() The kzfree() function is normally used to clear some sensitive information, like encryption keys, in the buffer before freeing it back to the pool. Memset() is currently used for buffer clearing. However unlikely, there is still a non-zero probability that the compiler may choose to optimize away the memory clearing especially if LTO is being used in the future. To make sure that this optimization will never happen, memzero_explicit(), which is introduced in v3.18, is now used in kzfree() to future-proof it.

[merged] mm-slab-fix-sign-conversion-problem-in-memcg_uncharge_slab.patch removed from -mm tree

by Andrew Morton

The patch titled Subject: mm, slab: fix sign conversion problem in memcg_uncharge_slab() has been removed from the -mm tree. Its filename was mm-slab-fix-sign-conversion-problem-in-memcg_uncharge_slab.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Waiman Long <longman(a)redhat.com> Subject: mm, slab: fix sign conversion problem in memcg_uncharge_slab() It was found that running the LTP test on a PowerPC system could produce erroneous values in /proc/meminfo, like: MemTotal: 531915072 kB MemFree: 507962176 kB MemAvailable: 1100020596352 kB Using bisection, the problem is tracked down to commit 9c315e4d7d8c ("mm: memcg/slab: cache page number in memcg_(un)charge_slab()"). In memcg_uncharge_slab() with a "int order" argument: unsigned int nr_pages = 1 << order; : mod_lruvec_state(lruvec, cache_vmstat_idx(s), -nr_pages); The mod_lruvec_state() function will eventually call the __mod_zone_page_state() which accepts a long argument. Depending on the compiler and how inlining is done, "-nr_pages" may be treated as a negative number or a very large positive number. Apparently, it was treated as a large positive number in that PowerPC system leading to incorrect stat counts. This problem hasn't been seen in x86-64 yet, perhaps the gcc compiler there has some slight difference in behavior. It is fixed by making nr_pages a signed value. For consistency, a similar change is applied to memcg_charge_slab() as well.

[merged] mm-compaction-make-capture-control-handling-safe-wrt-interrupts.patch removed from -mm tree

by Andrew Morton

The patch titled Subject: mm, compaction: make capture control handling safe wrt interrupts has been removed from the -mm tree. Its filename was mm-compaction-make-capture-control-handling-safe-wrt-interrupts.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, compaction: make capture control handling safe wrt interrupts Hugh reports: : While stressing compaction, one run oopsed on NULL capc->cc in : __free_one_page()'s task_capc(zone): compact_zone_order() had been : interrupted, and a page was being freed in the return from interrupt. : : Though you would not expect it from the source, both gccs I was using (a : 4.8.1 and a 7.5.0) had chosen to compile compact_zone_order() with the : ".cc = &cc" implemented by mov %rbx,-0xb0(%rbp) immediately before callq : compact_zone - long after the "current->capture_control = &capc". An : interrupt in between those finds capc->cc NULL (zeroed by an earlier rep : stos). : : This could presumably be fixed by a barrier() before setting : current->capture_control in compact_zone_order(); but would also need more : care on return from compact_zone(), in order not to risk leaking a page : captured by interrupt just before capture_control is reset. : : Maybe that is the preferable fix, but I felt safer for task_capc() to : exclude the rather surprising possibility of capture at interrupt time. I have checked that gcc10 also behaves the same. The advantage of fix in compact_zone_order() is that we don't add another test in the page freeing hot path, and that it might prevent future problems if we stop exposing pointers to uninitialized structures in current task. So this patch implements the suggestion for compact_zone_order() with barrier() (and WRITE_ONCE() to prevent store tearing) for setting current->capture_control, and prevents page leaking with WRITE_ONCE/READ_ONCE in the proper order.

Repeatable hard lockup running strace testsuite on 4.19.98+ onwards

by Steve McIntyre

Hi folks, I'm the maintainer in Debian for strace. Trying to reproduce https://bugs.debian.org/963462 on my machine (Thinkpad T470), I've found a repeatable hard lockup running the strace testsuite. Each time it seems to have failed in a slightly different place in the testsuite (suggesting it's not one particular syscall test that's triggering the failure). I initially found this using Debian's current Buster kernel (4.19.118+2+deb10u1), then backtracking I found that 4.19.98+1+deb10u1 worked fine. I've bisected to find the failure point along the linux-4.19.y stable branch and what I've got to is the following commit: e58f543fc7c0926f31a49619c1a3648e49e8d233 is the first bad commit commit e58f543fc7c0926f31a49619c1a3648e49e8d233 Author: Jann Horn <jannh(a)google.com> Date: Thu Sep 13 18:12:09 2018 +0200 apparmor: don't try to replace stale label in ptrace access check [ Upstream commit 1f8266ff58840d698a1e96d2274189de1bdf7969 ] As a comment above begin_current_label_crit_section() explains, begin_current_label_crit_section() must run in sleepable context because when label_is_stale() is true, aa_replace_current_label() runs, which uses prepare_creds(), which can sleep. Until now, the ptrace access check (which runs with a task lock held) violated this rule. Also add a might_sleep() assertion to begin_current_label_crit_section(), because asserts are less likely to be ignored than comments. Fixes: b2d09ae449ced ("apparmor: move ptrace checks to using labels") Signed-off-by: Jann Horn <jannh(a)google.com> Signed-off-by: John Johansen <john.johansen(a)canonical.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> :040000 040000 ca92f885a38c1747b812116f19de6967084a647e 865a227665e460e159502f21e8a16e6fa590bf50 M security Considering I'm running strace build tests to provoke this bug, finding the failure in a commit talking about ptrace changes does look very suspicious...! Annoyingly, I can't reproduce this on my disparate other machines here, suggesting it's maybe(?) timing related. Hope this helps - happy to give more information, test things, etc. -- Steve McIntyre, Cambridge, UK. steve(a)einval.com "Managing a volunteer open source project is a lot like herding kittens, except the kittens randomly appear and disappear because they have day jobs." -- Matt Mackall

patch "usb: cdns3: trace: using correct dir value" added to usb-linus

[PATCH v3] media: cros-ec-cec: do not bail on device_init_wakeup failure

by Dariusz Marcinkiewicz

Do not fail probing when device_init_wakeup fails. Also clear wakeup on remove. device_init_wakeup fails when the device is already enabled as wakeup device. Hence, the driver fails to probe the device if: - The device has already been enabled for wakeup (via /proc/acpi/wakeup) - The driver has been unloaded and is being loaded again. This goal of the patch is to fix the above cases. Overwhelming majority of the drivers do not consider device_init_wakeup failure as a fatal error and proceed regardless of whether it succeeds or not. Changes since v2: - disabled wakeup in remove - CC'ing stable - description fixed Changes since v1: - added Fixes tag Fixes: cd70de2d356ee ("media: platform: Add ChromeOS EC CEC driver") Cc: stable(a)vger.kernel.org Signed-off-by: Dariusz Marcinkiewicz <darekm(a)google.com> --- drivers/media/cec/platform/cros-ec/cros-ec-cec.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/drivers/media/cec/platform/cros-ec/cros-ec-cec.c b/drivers/media/cec/platform/cros-ec/cros-ec-cec.c index 0e7e2772f08f..3881ed7bc3d9 100644 --- a/drivers/media/cec/platform/cros-ec/cros-ec-cec.c +++ b/drivers/media/cec/platform/cros-ec/cros-ec-cec.c @@ -277,12 +277,6 @@ static int cros_ec_cec_probe(struct platform_device *pdev) platform_set_drvdata(pdev, cros_ec_cec); cros_ec_cec->cros_ec = cros_ec; - ret = device_init_wakeup(&pdev->dev, 1); - if (ret) { - dev_err(&pdev->dev, "failed to initialize wakeup\n"); - return ret; - } - cros_ec_cec->adap = cec_allocate_adapter(&cros_ec_cec_ops, cros_ec_cec, DRV_NAME, CEC_CAP_DEFAULTS | @@ -310,6 +304,8 @@ static int cros_ec_cec_probe(struct platform_device *pdev) if (ret < 0) goto out_probe_notify; + device_init_wakeup(&pdev->dev, 1); + return 0; out_probe_notify: @@ -339,6 +335,8 @@ static int cros_ec_cec_remove(struct platform_device *pdev) cros_ec_cec->adap); cec_unregister_adapter(cros_ec_cec->adap); + device_init_wakeup(&pdev->dev, 0); + return 0; } -- 2.27.0.212.ge8ba1cc988-goog

[PATCH] powerpc/fsl_booke/32: fix build with CONFIG_RANDOMIZE_BASE

by Arseny Solokha

Building the current 5.8 kernel for a e500 machine with CONFIG_RANDOMIZE_BASE set yields the following failure: arch/powerpc/mm/nohash/kaslr_booke.c: In function 'kaslr_early_init': arch/powerpc/mm/nohash/kaslr_booke.c:387:2: error: implicit declaration of function 'flush_icache_range'; did you mean 'flush_tlb_range'? [-Werror=implicit-function-declaration] Indeed, including asm/cacheflush.h into kaslr_booke.c fixes the build. The issue dates back to the introduction of that file and probably went unnoticed because there's no in-tree defconfig with CONFIG_RANDOMIZE_BASE set.

[patch 31/32] mm/memory_hotplug.c: fix false softlockup during pfn range removal

by Andrew Morton

From: Ben Widawsky <ben.widawsky(a)intel.com> Subject: mm/memory_hotplug.c: fix false softlockup during pfn range removal When working with very large nodes, poisoning the struct pages (for which there will be very many) can take a very long time. If the system is using voluntary preemptions, the software watchdog will not be able to detect forward progress. This patch addresses this issue by offering to give up time like __remove_pages() does. This behavior was introduced in v5.6 with: commit d33695b16a9f ("mm/memory_hotplug: poison memmap in remove_pfn_range_from_zone()") Alternately, init_page_poison could do this cond_resched(), but it seems to me that the caller of init_page_poison() is what actually knows whether or not it should relax its own priority. Based on Dan's notes, I think this is perfectly safe: commit f931ab479dd2 ("mm: fix devm_memremap_pages crash, use mem_hotplug_{begin, done}") Aside from fixing the lockup, it is also a friendlier thing to do on lower core systems that might wipe out large chunks of hotplug memory (probably not a very common case). Fixes this kind of splat: [ 352.142079] watchdog: BUG: soft lockup - CPU#46 stuck for 22s!

A bit of fluctuation around the target protection isn't a big deal, but we need to handle the div0 case.

[patch 12/32] mm/slab: use memzero_explicit() in kzfree()

by Andrew Morton

From: Waiman Long <longman(a)redhat.com> Subject: mm/slab: use memzero_explicit() in kzfree() The kzfree() function is normally used to clear some sensitive information, like encryption keys, in the buffer before freeing it back to the pool. Memset() is currently used for buffer clearing. However unlikely, there is still a non-zero probability that the compiler may choose to optimize away the memory clearing especially if LTO is being used in the future. To make sure that this optimization will never happen, memzero_explicit(), which is introduced in v3.18, is now used in kzfree() to future-proof it.

[patch 11/32] mm, slab: fix sign conversion problem in memcg_uncharge_slab()

by Andrew Morton

From: Waiman Long <longman(a)redhat.com> Subject: mm, slab: fix sign conversion problem in memcg_uncharge_slab() It was found that running the LTP test on a PowerPC system could produce erroneous values in /proc/meminfo, like: MemTotal: 531915072 kB MemFree: 507962176 kB MemAvailable: 1100020596352 kB Using bisection, the problem is tracked down to commit 9c315e4d7d8c ("mm: memcg/slab: cache page number in memcg_(un)charge_slab()"). In memcg_uncharge_slab() with a "int order" argument: unsigned int nr_pages = 1 << order; : mod_lruvec_state(lruvec, cache_vmstat_idx(s), -nr_pages); The mod_lruvec_state() function will eventually call the __mod_zone_page_state() which accepts a long argument. Depending on the compiler and how inlining is done, "-nr_pages" may be treated as a negative number or a very large positive number. Apparently, it was treated as a large positive number in that PowerPC system leading to incorrect stat counts. This problem hasn't been seen in x86-64 yet, perhaps the gcc compiler there has some slight difference in behavior. It is fixed by making nr_pages a signed value. For consistency, a similar change is applied to memcg_charge_slab() as well.

[patch 05/32] ocfs2: avoid inode removal while nfsd is accessing it

by Andrew Morton

From: Junxiao Bi <junxiao.bi(a)oracle.com> Subject: ocfs2: avoid inode removal while nfsd is accessing it Patch series "ocfs2: fix nfsd over ocfs2 issues", v2. This is a series of patches to fix issues on nfsd over ocfs2. patch 1 is to avoid inode removed while nfsd access it patch 2 & 3 is to fix a panic issue. This patch (of 4): When nfsd is getting file dentry using handle or parent dentry of some dentry, one cluster lock is used to avoid inode removed from other node, but it still could be removed from local node, so use a rw lock to avoid this.

[patch 03/32] mm, compaction: make capture control handling safe wrt interrupts

by Andrew Morton

From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, compaction: make capture control handling safe wrt interrupts Hugh reports: : While stressing compaction, one run oopsed on NULL capc->cc in : __free_one_page()'s task_capc(zone): compact_zone_order() had been : interrupted, and a page was being freed in the return from interrupt. : : Though you would not expect it from the source, both gccs I was using (a : 4.8.1 and a 7.5.0) had chosen to compile compact_zone_order() with the : ".cc = &cc" implemented by mov %rbx,-0xb0(%rbp) immediately before callq : compact_zone - long after the "current->capture_control = &capc". An : interrupt in between those finds capc->cc NULL (zeroed by an earlier rep : stos). : : This could presumably be fixed by a barrier() before setting : current->capture_control in compact_zone_order(); but would also need more : care on return from compact_zone(), in order not to risk leaking a page : captured by interrupt just before capture_control is reset. : : Maybe that is the preferable fix, but I felt safer for task_capc() to : exclude the rather surprising possibility of capture at interrupt time. I have checked that gcc10 also behaves the same. The advantage of fix in compact_zone_order() is that we don't add another test in the page freeing hot path, and that it might prevent future problems if we stop exposing pointers to uninitialized structures in current task. So this patch implements the suggestion for compact_zone_order() with barrier() (and WRITE_ONCE() to prevent store tearing) for setting current->capture_control, and prevents page leaking with WRITE_ONCE/READ_ONCE in the proper order.

[PATCH drivers/misc v2 2/4] lkdtm/heap: Avoid edge and middle of slabs

Har har, after I moved the slab freelist pointer into the middle of the slab, now it looks like the contents are getting poisoned. Adjust the test to avoid the freelist pointer again.

[PATCH] net: bridge: enfore alignment for ethernet address

by Thomas Martitz

The eth_addr member is passed to ether_addr functions that require 2-byte alignment, therefore the member must be properly aligned to avoid unaligned accesses. The problem is in place since the initial merge of multicast to unicast: commit 6db6f0eae6052b70885562e1733896647ec1d807 bridge: multicast to unicast Fixes: 6db6f0eae605 ("bridge: multicast to unicast") Cc: Roopa Prabhu <roopa(a)cumulusnetworks.com> Cc: Nikolay Aleksandrov <nikolay(a)cumulusnetworks.com> Cc: David S.

[PATCH v2] net: phy: mscc: avoid skcipher API for single block AES encryption

by Ard Biesheuvel

The skcipher API dynamically instantiates the transformation object on request that implements the requested algorithm optimally on the given platform. This notion of optimality only matters for cases like bulk network or disk encryption, where performance can be a bottleneck, or in cases where the algorithm itself is not known at compile time. In the mscc case, we are dealing with AES encryption of a single block, and so neither concern applies, and we are better off using the AES library interface, which is lightweight and safe for this kind of use. Note that the scatterlist API does not permit references to buffers that are located on the stack, so the existing code is incorrect in any case, but avoiding the skcipher and scatterlist APIs entirely is the most straight-forward approach to fixing this.
