commit 133e049a upstream. Unsanitized pages trigger WARN_ON() unconditionally, which can panic the whole computer, if /proc/sys/kernel/panic_on_warn is set. In sgx_init(), if misc_register() fails or misc_register() succeeds but neither sgx_drv_init() nor sgx_vepc_init() succeeds, then ksgxd will be prematurely stopped. This may leave unsanitized pages, which will result a false warning. Refine __sgx_sanitize_pages() to return: 1. Zero when the sanitization process is complete or ksgxd has been requested to stop. 2. The number of unsanitized pages otherwise. Fixes: 51ab30eb ("x86/sgx: Replace section->init_laundry_list with sgx_dirty_page_list") Reported-by:

commit 6726d552 upstream. Access to registers is guarded by ingenic_tcu_{enable,disable}_regs() so the stop bit can be cleared before accessing a timer channel, but those functions did not clear the stop bit on SoCs with a global TCU clock gate. Testing on the X1000 has revealed that the stop bits must be cleared _and_ the global TCU clock must be ungated to access timer registers. This appears to be the norm on Ingenic SoCs, and is specified in the documentation for the X1000 and numerous JZ47xx SoCs. If the stop bit isn't cleared, register writes don't take effect and the system can be left in a broken state, eg. the watchdog timer may not run. The bug probably went unnoticed because stop bits are zeroed when the SoC is reset, and the kernel does not set them unless a timer gets disabled at runtime. However, it is possible that a bootloader or a previous kernel (if using kexec) leaves the stop bits set and we should not rely on them being cleared. Fixing this is easy: have ingenic_tcu_{enable,disable}_regs() always clear the stop bit, regardless of the presence of a global TCU gate. Reviewed-by:

commit e62563db upstream. Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1 (chapters 57.9 and 6.4.5 respectively). Without this, trying to read the revision number results in 0 on all revisions, causing the i.MX6 quirk to apply on all platforms, which in turn causes the driver to synthesise power button release events instead of passing the real one as they happen even on platforms like i.MX8 where that's not wanted.

Since cgroup_mutex is still held, it is guaranteed that the cgroup will be alive and the reference can be taken on it. However similar guarantee can be provided without depending on the cgroup_mutex and potentially reducing avenues of cgroup_mutex contentions. The kernfs_node's priv pointer is RCU protected pointer and with just rcu read lock we can grab the reference on the cgroup without cgroup_mutex. So, remove cgroup_mutex from them. Signed-off-by:

Note that the device can boot up with working speakers and micmute LED without this patch, but the success rate would be quite low (order of 16 working boots across 709 boots) at least for the built-in drivers scenario. This also means that there are some timing issues during early boot and this patch is a workaround. With this patch applied speakers and headphones are consistenly working, as well as mute/micmute LEDs and the internal microphone. Signed-off-by:

[ Upstream commit ead3d3c5 ] We fixed the potential deadlock at dynamic unbinding the HD-audio codec at the commit 7206998f ("ALSA: hda: Fix potential deadlock at codec unbinding"), but ironically, this caused another potential deadlock. The current code uses refcount_dec() and waits for the pending task with wait_event for dropping the refcount to 0. This works fine when PCMs are assigned and actually waiting for the refcount drop. Meanwhile, when there was no PCM assigned, the refcount_dec() call itself was supposed to drop to zero -- alas, it doesn't in reality; refcount_dec() complains, spews kernel warning and it saturates instead of dropping to 0, due to the nature of refcount_dec() implementation. This eventually blocks the wait_event() wakeup and the code get stuck there. For avoiding the problem, we call refcount_dec_and_test() and skips the sync-wait if it already reaches to zero. The patch does a slight code reshuffling to make sure to invoke other disconnect calls before the sync-wait, too. Fixes: 7206998f ("ALSA: hda: Fix potential deadlock at codec unbinding") Reported-by:

commit a9f2a293 upstream. Curently we don't use any preallocation when a file is already closed when allocating blocks (from writeback code when converting delayed allocation). However for small files, using locality group preallocation is actually desirable as that is not specific to a particular file. Rather it is a method to pack small files together to reduce fragmentation and for that the fact the file is closed is actually even stronger hint the file would benefit from packing. So change the logic to allow locality group preallocation in this case. Fixes: 196e402a ("ext4: improve cr 0 / cr 1 group scanning") CC: stable@kernel.org Reported-and-tested-by:

commit 1940265e upstream. mb_set_largest_free_order() updates lists containing groups with largest chunk of free space of given order. The way it updates it leads to always moving the group to the tail of the list. Thus allocations looking for free space of given order effectively end up cycling through all groups (and due to initialization in last to first order). This spreads allocations among block groups which reduces performance for rotating disks or low-end flash media. Change mb_set_largest_free_order() to only update lists if the order of the largest free chunk in the group changed.

commit 80fa46d6 upstream. This patch avoids threads live-locking for hours when a large number threads are competing over the last few free extents as they blocks getting added and removed from preallocation pools. From our bug reporter: A reliable way for triggering this has multiple writers continuously write() to files when the filesystem is full, while small amounts of space are freed (e.g. by truncating a large file -1MiB at a time). In the local filesystem, this can be done by simply not checking the return code of write (0) and/or the error (ENOSPACE) that is set. Over NFS with an async mount, even clients with proper error checking will behave this way since the linux NFS client implementation will not propagate the server errors [the write syscalls immediately return success] until the file handle is closed. This leads to a situation where NFS clients send a continuous stream of WRITE rpcs which result in ERRNOSPACE -- but since the client isn't seeing this, the stream of writes continues at maximum network speed. When some space does appear, multiple writers will all attempt to claim it for their current write. For NFS, we may see dozens to hundreds of threads that do this. The real-world scenario of this is database backup tooling (in particular, github.com/mdkent/percona-xtrabackup) which may write large files (>1TiB) to NFS for safe keeping. Some temporary files are written, rewound, and read back -- all before closing the file handle (the temp file is actually unlinked, to trigger automatic deletion on close/crash.) An application like this operating on an async NFS mount will not see an error code until TiB have been written/read. The lockup was observed when running this database backup on large filesystems (64 TiB in this case) with a high number of block groups and no free space. Fragmentation is generally not a factor in this filesystem (~thousands of large files, mostly contiguous except for the parts written while the filesystem is at capacity.) Signed-off-by:

And this will lead to problems because the EXT_FIRST_INDEX() and EXT_LAST_INDEX() will return garbage and result in this: [ 135.245946] ------------[ cut here ]------------ [ 135.247579] kernel BUG at fs/ext4/extents.c:2258!

commit 613c5a85 upstream. Currently the Orlov inode allocator searches for free inodes for a directory only in flex block groups with at most inodes_per_group/16 more directory inodes than average per flex block group. However with growing size of flex block group this becomes unnecessarily strict. Scale allowed difference from average directory count per flex block group with flex block group size as we do with other metrics. Tested-by:

commit 67feaba4 upstream. The "hmem" platform-devices that are created to represent the platform-advertised "Soft Reserved" memory ranges end up inserting a resource that causes the iomem_resource tree to look like this: 340000000-43fffffff : hmem.0 340000000-43fffffff : Soft Reserved 340000000-43fffffff : dax0.0 This is because insert_resource() reparents ranges when they completely intersect an existing range. This matters because code that uses region_intersects() to scan for a given IORES_DESC will only check that top-level 'hmem.0' resource and not the 'Soft Reserved' descendant. So, to support EINJ (via einj_error_inject()) to inject errors into memory hosted by a dax-device, be sure to describe the memory as IORES_DESC_SOFT_RESERVED. This is a follow-on to: commit b13a3e5f ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP") ...that fixed EINJ support for "Soft Reserved" ranges in the first instance. Fixes: 262b45ae ("x86/efi: EFI soft reservation to E820 enumeration") Reported-by:

[ Upstream commit c0feea59 ] Like Hillf Danton mentioned syzbot should have been able to catch cancel_work_sync() in work context by checking lockdep_map in __flush_work() for both flush and cancel. in [1], being unable to report an obvious deadlock scenario shown below is broken. From locking dependency perspective, sync version of cancel request should behave as if flush request, for it waits for completion of work if that work has already started execution. ---------- #include <linux/module.h> #include <linux/sched.h> static DEFINE_MUTEX(mutex); static void work_fn(struct work_struct *work) { schedule_timeout_uninterruptible(HZ / 5); mutex_lock(&mutex); mutex_unlock(&mutex); } static DECLARE_WORK(work, work_fn); static int __init test_init(void) { schedule_work(&work); schedule_timeout_uninterruptible(HZ / 10); mutex_lock(&mutex); cancel_work_sync(&work); mutex_unlock(&mutex); return -EINVAL; } module_init(test_init); MODULE_LICENSE("GPL"); ---------- The check this patch restores was added by commit 0976dfc1 ("workqueue: Catch more locking problems with flush_work()"). Then, lockdep's crossrelease feature was added by commit b09be676 ("locking/lockdep: Implement the 'crossrelease' feature"). As a result, this check was once removed by commit fd1a5b04 ("workqueue: Remove now redundant lock acquisitions wrt. workqueue flushes"). But lockdep's crossrelease feature was removed by commit e966eaee ("locking/lockdep: Remove the cross-release locking checks"). At this point, this check should have been restored. Then, commit d6e89786 ("workqueue: skip lockdep wq dependency in cancel_work_sync()") introduced a boolean flag in order to distinguish flush_work() and cancel_work_sync(), for checking "struct workqueue_struct" dependency when called from cancel_work_sync() was causing false positives. Then, commit 87915adc ("workqueue: re-add lockdep dependencies for flushing") tried to restore "struct work_struct" dependency check, but by error checked this boolean flag. Like an example shown above indicates, "struct work_struct" dependency needs to be checked for both flush_work() and cancel_work_sync().

Commit a0f7e7f7 ("drm/amd/display: fix i386 frame size warning") aimed to address this for i386 but it did not help x86_64. To reduce the amount of stack space that dml30_ModeSupportAndSystemConfigurationFull() uses, mark UseMinimumDCFCLK() as noinline, using the _for_stack variant for documentation. While this will increase the total amount of stack usage between the two functions (1632 and 1304 bytes respectively), it will make sure both stay below the limit of 2048 bytes for these files. The aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage so it should not be reverted in favor of this change.
