commit 9acc54be upstream. Just like for CCMP we need to check that for GCMP the fragments have PNs that increment by one; the spec was updated to fix this security issue and now has the following text: The receiver shall discard MSDUs and MMPDUs whose constituent MPDU PN values are not incrementing in steps of 1. Adapt the code for CCMP to work for GCMP as well, luckily the relevant fields already alias each other so no code duplication is needed (just check the aliasing with BUILD_BUG_ON.) Signed-off-by:

However, this is an enum ctl, and it has to be accessed via value.enumerated.item[]. The former is long while the latter is unsigned int, so they don't align.

commit 1ee9f4bd upstream. This issue is caused by commit 02323db1 ("cifs: fix cifs_uniqueid_to_ino_t not to ever return 0"), when BITS_PER_LONG is 64 on s390x, the corresponding cifs_uniqueid_to_ino_t() function will cast 64-bit fileid to 32-bit by using (ino_t)fileid, because ino_t (typdefed __kernel_ino_t) is int type. It's defined in arch/s390/include/uapi/asm/posix_types.h #ifndef __s390x__ typedef unsigned long __kernel_ino_t; ... #else /* __s390x__ */ typedef unsigned int __kernel_ino_t; So the #ifdef condition is wrong for s390x, we can just still use one cifs_uniqueid_to_ino_t() function with comparing sizeof(ino_t) and sizeof(u64) to choose the correct execution accordingly.

commit deb7deff upstream. When opening a file, SMB2_open() attempts to parse the lease state from the SMB2 CREATE Response. However, the parsing code was not careful to ensure that the create contexts are not empty or invalid, which can lead to out- of-bounds memory access. This can be seen easily by trying to read a file from a OSX 10.11 SMB3 server.

commit b24e7ad1 upstream. X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes incompatible with IA32. This results in NOTTY error when the ioctl is issued. Meanwhile, this struct in X32 is essentially identical with the one in X86-64, so we can just bypassing to the existing code for this specific compat ioctl. Signed-off-by:

commit 2251fbbc upstream. Like the previous fixes for ctl and PCM, we need a fix for incompatible X32 ABI regarding the rawmidi: namely, struct snd_rawmidi_status has the timespec, and the size and the alignment on X32 differ from IA32.

commit 513ace79 upstream. X32 ABI uses the 64bit timespec in addition to 64bit alignment of 64bit values. This leads to incompatibilities in some PCM ioctls involved with snd_pcm_channel_info, snd_pcm_status and snd_pcm_sync_ptr structs. Fix the PCM compat ABI for these ioctls like the previous commit for ctl API. Reported-by:

commit 6236d8bb upstream. The X32 ABI takes the same alignment like x86-64, and this may result in the incompatible struct size from ia32. Unfortunately, we hit this in some control ABI: struct snd_ctl_elem_value differs between them due to the position of 64bit variable array. This ends up with the unknown ioctl (ENOTTY) error. The fix is to add the compat entries for the new aligned struct. Reported-and-tested-by:

commit dfd55ad8 upstream. Commit dd006da2 ("arm64: mm: increase VA range of identity map") made some changes to the memory mapping code to allow physical memory to reside at an offset that exceeds the size of the virtual mapping. However, since the size of the vmemmap area is proportional to the size of the VA area, but it is populated relative to the physical space, we may end up with the struct page array being mapped outside of the vmemmap region. For instance, on my Seattle A0 box, I can see the following output in the dmesg log. vmemmap : 0xffffffbdc0000000 - 0xffffffbfc0000000 ( 8 GB maximum) 0xffffffbfc0000000 - 0xffffffbfd0000000 ( 256 MB actual) We can fix this by deciding that the vmemmap region is not a projection of the physical space, but of the virtual space above PAGE_OFFSET, i.e., the linear region. This way, we are guaranteed that the vmemmap region is of sufficient size, and we can even reduce the size by half. Signed-off-by:

commit 70e4da7a upstream. Commit 172b2386 ("KVM: x86: fix missed hardware breakpoints", 2016-02-10) worked around a case where the debug registers are not loaded correctly on preemption and on the first entry to KVM_RUN. However, Xiao Guangrong pointed out that the root cause must be that KVM_DEBUGREG_BP_ENABLED is not being set correctly. This can indeed happen due to the lazy debug exit mechanism, which does not call kvm_update_dr7. Fix it by replacing the existing loop (more or less equivalent to kvm_update_dr0123) with calls to all the kvm_update_dr* functions. Fixes: 172b2386Reviewed-by:

commit a1e533ec upstream. Since commit 27a4c827 fbcon: use the cursor blink interval provided by vt two attempts have been made at fixing a possible hang caused by cursor_timer_handler. That function registers a timer to be triggered at "jiffies + fbcon_ops.cur_blink_jiffies". A new case had been encountered during initialisation of clcd-pl11x: fbcon_fb_registered do_fbcon_takeover -> do_register_con_driver fbcon_startup (A) add_cursor_timer (with cur_blink_jiffies = 0) -> do_bind_con_driver visual_init fbcon_init (B) cur_blink_jiffies = msecs_to_jiffies(vc->vc_cur_blink_ms); If we take an softirq anywhere between A and B (and we do), cursor_timer_handler executes indefinitely. Instead of patching all possible paths that lead to this case one at a time, fix the issue at the source and initialise cur_blink_jiffies to 200ms when allocating fbcon_ops. This was its default value before aforesaid commit. fbcon_cursor or fbcon_init will refine this value downstream. Signed-off-by:

commit e9a2d81b upstream. gs_destroy_candev() erroneously calls kfree() on a struct gs_can *, which is allocated through alloc_candev() and should instead be freed using free_candev() alone. The inappropriate use of kfree() causes the kernel to hang when gs_destroy_candev() is called. Only the struct gs_usb * which is allocated through kzalloc() should be freed using kfree() when the device is disconnected. Signed-off-by:

commit 4ee34ea3 upstream. The id buffer in ata_device is a DMA target, but it isn't explicitly cacheline aligned. Due to this, adjacent fields can be overwritten with stale data from memory on non coherent architectures. As a result, the kernel is sometimes unable to communicate with an ATA device. Fix this by ensuring that the id buffer is cacheline aligned. This issue is similar to that fixed by Commit 84bda12a ("libata: align ap->sector_buf"). Signed-off-by:

commit 358875fd upstream. The AMD Family 15h Models 30h-3Fh (Kaveri) BIOS and Kernel Developer's Guide omitted part of the BIOS IOMMU L2 register setup specification. Without this setup the IOMMU L2 does not fully respect write permissions when handling an ATS translation request. The IOMMU L2 will set PTE dirty bit when handling an ATS translation with write permission request, even when PTE RW bit is clear. This may occur by direct translation (which would cause a PPR) or by prefetch request from the ATC. This is observed in practice when the IOMMU L2 modifies a PTE which maps a pagecache page. The ext4 filesystem driver BUGs when asked to writeback these (non-modified) pages. Enable ATS write permission check in the Kaveri IOMMU L2 if BIOS has not. Signed-off-by:

commit be629c62 upstream. When a directory is deleted, we don't take too much care about killing off all the dirents that belong to it — on the basis that on remount, the scan will conclude that the directory is dead anyway. This doesn't work though, when the deleted directory contained a child directory which was moved *out*. In the early stages of the fs build we can then end up with an apparent hard link, with the child directory appearing both in its true location, and as a child of the original directory which are this stage of the mount process we don't *yet* know is defunct. To resolve this, take out the early special-casing of the "directories shall not have hard links" rule in jffs2_build_inode_pass1(), and let the normal nlink processing happen for directories as well as other inodes. Then later in the build process we can set ic->pino_nlink to the parent inode#, as is required for directories during normal operaton, instead of the nlink. And complain only *then* about hard links which are still in evidence even after killing off all the unreachable paths. Reported-by:

commit 157078f6 upstream. This reverts commit 5ffd3412 ("jffs2: Fix lock acquisition order bug in jffs2_write_begin"). The commit modified jffs2_write_begin() to remove a deadlock with jffs2_garbage_collect_live(), but this introduced new deadlocks found by multiple users. page_lock() actually has to be called before mutex_lock(&c->alloc_sem) or mutex_lock(&f->sem) because jffs2_write_end() and jffs2_readpage() are called with the page locked, and they acquire c->alloc_sem and f->sem, resp. In other words, the lock order in jffs2_write_begin() was correct, and it is the jffs2_garbage_collect_live() path that has to be changed. Revert the commit to get rid of the new deadlocks, and to clear the way for a better fix of the original deadlock. Reported-by:

commit d144dfea upstream. If we use USB ID pin as wakeup source, and there is a USB block device on this USB OTG (ID) cable, the system will be deadlock after system resume. The root cause for this problem is: the workqueue ci_otg may try to remove hcd before the driver resume has finished, and hcd will disconnect the device on it, then, it will call device_release_driver, and holds the device lock "dev->mutex", but it is never unlocked since it waits workqueue writeback to run to flush the block information, but the workqueue writeback is freezable, it is not thawed before driver resume has finished. When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it tries to get its device lock "dev->mutex", but it can't get it forever, then the deadlock occurs. Below call stacks show the situation. So, in order to fix this problem, we need to change workqueue ci_otg as freezable, then the work item in this workqueue will be run after driver's resume, this workqueue will not be blocked forever like above case since the workqueue writeback has been thawed too. Tested at: i.mx6qdl-sabresd and i.mx6sx-sdb.

commit 7a36b930 upstream. The value 5000 was put here with the addition of the timeout field to ieee80211_start_tx_ba_session. It was originally added in mac80211 to save resources for drivers like iwlwifi, which only supports a limited number of concurrent aggregation sessions. Since iwlwifi does not use minstrel_ht and other drivers don't need this, 0 is a better default - especially since there have been recent reports of aggregation setup related issues reproduced with ath9k. This should improve stability without causing any adverse effects. Acked-by:

commit 316fa9e0 upstream. Lockdep warns of a potential lock inversion, i2s->lock is held numerous times whilst we are under the substream lock (snd_pcm_stream_lock). If we use the IRQ unsafe spin lock calls, you can also end up locking snd_pcm_stream_lock whilst under i2s->lock (if an IRQ happens whilst we are holding i2s->lock). This could result in deadlock.
