commit 1c32ca5d upstream. When deciding whether a guest has to be stopped we check whether this is a private interrupt or not. Unfortunately, there's an off-by-one bug here, and we fail to recognize a whole range of interrupts as being global (GICv2 SPIs 32-63). Fix the condition from > to be >=.

commit 11f5efc3 upstream. x86_64 lazily maps in the vmalloc pages, and the way this works with per_cpu areas can be complex, to say the least. Mappings may happen at boot up, and if nothing synchronizes the page tables, those page mappings may not be synced till they are used. This causes issues for anything that might touch one of those mappings in the path of the page fault handler. When one of those unmapped mappings is touched in the page fault handler, it will cause another page fault, which in turn will cause a page fault, and leave us in a loop of page faults. Commit 763802b5 ("x86/mm: split vmalloc_sync_all()") split vmalloc_sync_all() into vmalloc_sync_unmappings() and vmalloc_sync_mappings(), as on system exit, it did not need to do a full sync on x86_64 (although it still needed to be done on x86_32). By chance, the vmalloc_sync_all() would synchronize the page mappings done at boot up and prevent the per cpu area from being a problem for tracing in the page fault handler. But when that synchronization in the exit of a task became a nop, it caused the problem to appear.

commit 0ed08fad upstream. The syzbot fuzzer discovered a bad race between in the usbhid driver between usbhid_stop() and usbhid_close(). In particular, usbhid_stop() does: usb_free_urb(usbhid->urbin); ... usbhid->urbin = NULL; /* don't mess up next start */ and usbhid_close() does: usb_kill_urb(usbhid->urbin); with no mutual exclusion. If the two routines happen to run concurrently so that usb_kill_urb() is called in between the usb_free_urb() and the NULL assignment, it will access the deallocated urb structure -- a use-after-free bug. This patch adds a mutex to the usbhid private structure and uses it to enforce mutual exclusion of the usbhid_start(), usbhid_stop(), usbhid_open() and usbhid_close() callbacks.

commit 145cb2f7 upstream. When we start shutdown in sctp_sf_do_dupcook_a(), we want to bundle the SHUTDOWN with the COOKIE-ACK to ensure that the peer receives them at the same time and in the correct order. This bundling was broken by commit 4ff40b86 ("sctp: set chunk transport correctly when it's a new asoc"), which assigns a transport for the COOKIE-ACK, but not for the SHUTDOWN. Fix this by passing a reference to the COOKIE-ACK chunk as an argument to sctp_sf_do_9_2_start_shutdown() and onward to sctp_make_shutdown(). This way the SHUTDOWN chunk is assigned the same transport as the COOKIE-ACK chunk, which allows them to be bundled. In sctp_sf_do_9_2_start_shutdown(), the void *arg parameter was previously unused. Now that we're taking it into use, it must be a valid pointer to a chunk, or NULL. There is only one call site where it's not, in sctp_sf_autoclose_timer_expire(). Fix that too.

commit 778fbf41 upstream. We've recently switched from extracting the value of HID_DG_CONTACTMAX at a fixed offset (which may not be correct for all tablets) to injecting the report into the driver for the generic codepath to handle. Unfortunately, this change was made for *all* tablets, even those which aren't generic. Because `wacom_wac_report` ignores reports from non- generic devices, the contact count never gets initialized. Ultimately this results in the touch device itself failing to probe, and thus the loss of touch input. This commit adds back the fixed-offset extraction for non-generic devices.

[ Upstream commit c71c4e49 ] Fix the logic that sets the enable/disable flag for the source MAC filter according to firmware spec 1.7.1. In the original firmware spec. before 1.7.1, the VF spoof check flags were not latched after making the HWRM_FUNC_CFG call, so there was a need to keep the func_flags so that subsequent calls would perserve the VF spoof check setting. A change was made in the 1.7.1 spec so that the flags became latched. So we now set or clear the anti- spoof setting directly without retrieving the old settings in the stored vf->func_flags which are no longer valid. We also remove the unneeded vf->func_flags.

[ Upstream commit 980d6927 ] When an application connects to the TIPC topology server and subscribes to some services, a new connection is created along with some objects - 'tipc_subscription' to store related data correspondingly... However, there is one omission in the connection handling that when the connection or application is orderly shutdown (e.g. via SIGQUIT, etc.), the connection is not closed in kernel, the 'tipc_subscription' objects are not freed too. This results in: - The maximum number of subscriptions (65535) will be reached soon, new subscriptions will be rejected; - TIPC module cannot be removed (unless the objects are somehow forced to release first); The commit fixes the issue by closing the connection if the 'recvmsg()' returns '0' i.e. when the peer is shutdown gracefully. It also includes the other unexpected cases. Acked-by:

[ Upstream commit ab046a5d ] MACsec decryption always occurs in a softirq context. Since the FPU may not be usable in the softirq context, the call to decrypt may be scheduled on the cryptd work queue. The cryptd work queue does not provide ordering guarantees. Therefore, preserving order requires masking out ASYNC implementations of gcm(aes). For instance, an Intel CPU with AES-NI makes available the generic-gcm-aesni driver from the aesni_intel module to implement gcm(aes). However, this implementation requires the FPU, so it is not always available to use from a softirq context, and will fallback to the cryptd work queue, which does not preserve frame ordering. With this change, such a system would select gcm_base(ctr(aes-aesni),ghash-generic). While the aes-aesni implementation prefers to use the FPU, it will fallback to the aes-asm implementation if unavailable. By using a synchronous version of gcm(aes), the decryption will complete before returning from crypto_aead_decrypt(). Therefore, the macsec_decrypt_done() callback will be called before returning from macsec_decrypt(). Thus, the order of calls to macsec_post_decrypt() for the frames is preserved. While it's presumable that the pure AES-NI version of gcm(aes) is more performant, the hybrid solution is capable of gigabit speeds on modest hardware. Regardless, preserving the order of frames is paramount for many network protocols (e.g., triggering TCP retries). Within the MACsec driver itself, the replay protection is tripped by the out-of-order frames, and can cause frames to be dropped. This bug has been present in this code since it was added in v4.6, however it may not have been noticed since not all CPUs have FPU offload available. Additionally, the bug manifests as occasional out-of-order packets that are easily misattributed to other network phenomena. When this code was added in v4.6, the crypto/gcm.c code did not restrict selection of the ghash function based on the ASYNC flag. For instance, x86 CPUs with PCLMULQDQ would select the ghash-clmulni driver instead of ghash-generic, which submits to the cryptd work queue if the FPU is busy. However, this bug was was corrected in v4.8 by commit b30bdfa8, and was backported all the way back to the v3.14 stable branch, so this patch should be applicable back to the v4.6 stable branch.

commit 26b1d3b5 upstream. The -modesetting ddx has a totally broken idea of how atomic works: - doesn't disable old connectors, assuming they get auto-disable like with the legacy setcrtc - assumes ASYNC_FLIP is wired through for the atomic ioctl - not a single call to TEST_ONLY Iow the implementation is a 1:1 translation of legacy ioctls to atomic, which is a) broken b) pointless. We already have bugs in both i915 and amdgpu-DC where this prevents us from enabling neat features. If anyone ever cares about atomic in X we can easily add a new atomic level (req->value == 2) for X to get back the shiny toys. Since these broken versions of -modesetting have been shipping, there's really no other way to get out of this bind. v2: - add an informational dmesg output (Rob, Ajax) - reorder after the DRIVER_ATOMIC check to avoid useless noise (Ilia) - allow req->value > 2 so that X can do another attempt at atomic in the future v3: Go with paranoid, insist that the X should be first (suggested by Rob) Cc: Ilia Mirkin <imirkin@alum.mit.edu> References: https://gitlab.freedesktop.org/xorg/xserver/issues/629 References: https://gitlab.freedesktop.org/xorg/xserver/merge_requests/180 References: abbc0697 ("drm/fb: revert the i915 Actually configure untiled displays from master") Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> (v1) Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> (v1) Cc: Michel Dänzer <michel@daenzer.net> Cc: Alex Deucher <alexdeucher@gmail.com> Cc: Adam Jackson <ajax@redhat.com> Acked-by:

commit 977dfef4 upstream. The commit 3c6fd1f0 ("ALSA: hda: Add driver blacklist") added a new blacklist for the devices that are known to have empty codecs, and one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f). However, it turned out that the very same PCI SSID is used for the previous model that does have the valid HD-audio codecs and the change broke the sound on it. Since the empty codec problem appear on the certain AMD platform (PCI ID 1022:1487), this patch changes the blacklist matching to both PCI ID and SSID using pci_match_id(). Also, the entry that was removed by the previous fix for ASUS ROG Zenigh II is re-added. Link: https://lore.kernel.org/r/20200424061222.19792-1-tiwai@suse.deSigned-off-by:

commit a8ff78f7 upstream. Some BIOS erroneously specifies write-combining BAR for intel-lpss-pci in MTRR. This will cause the system to hang during boot. If possible, this bug could be corrected with a firmware update. This patch use devm_ioremap_uc to overwrite/ignore the MTRR settings by forcing the use of strongly uncachable pages for intel-lpss. The BIOS bug is present on Dell XPS 13 7390 2-in-1: [ 0.001734] 5 base 4000000000 mask 6000000000 write-combining 4000000000-7fffffffff : PCI Bus 0000:00 4000000000-400fffffff : 0000:00:02.0 (i915) 4010000000-4010000fff : 0000:00:15.0 (intel-lpss-pci) Link: https://bugzilla.kernel.org/show_bug.cgi?id=203485 Cc: <stable@vger.kernel.org> # v4.19+ Tested-by:

commit 12dfd78e upstream. When starting shutdown in sctp_sf_do_dupcook_a(), get the value for SHUTDOWN Cumulative TSN Ack from the new association, which is reconstructed from the cookie, instead of the old association, which the peer doesn't have anymore. Otherwise the SHUTDOWN is either ignored or replied to with an ABORT by the peer because CTSN Ack doesn't match the peer's Initial TSN. Fixes: bdf6fa52 ("sctp: handle association restarts when the socket is closed.") Signed-off-by:

[ Upstream commit 3554e54a ] The driver is designed to drop Rx packets and reclaim the buffers when an allocation fails, and the network interface needs to safely handle this packet loss. Therefore, an allocation failure of Rx SKBs is relatively benign. However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing. This commit suppresses the warning messages to prevent scheduling problems while retaining the failure count in the statistics of the network interface. Signed-off-by:
