2022-10-19nvme: fix error pointer dereference in error handlingDan Carpenter

2022-10-19IB/hfi1: Correctly move list in sc_disable()Dean Luick
Commit 13bac861952a ("IB/hfi1: Fix abba locking issue with sc_disable()") incorrectly tries to move a list from one list head to another. The result is a kernel crash. The crash is triggered when a link goes down and there are waiters for a send to complete. The following signature is seen: BUG: kernel NULL pointer dereference, address: 0000000000000030 [...] Call Trace: sc_disable+0x1ba/0x240 [hfi1] pio_freeze+0x3d/0x60 [hfi1] handle_freeze+0x27/0x1b0 [hfi1] process_one_work+0x1b0/0x380 ? process_one_work+0x380/0x380 worker_thread+0x30/0x360 ? process_one_work+0x380/0x380 kthread+0xd7/0x100 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x1f/0x30 The fix is to use the correct call to move the list.

2022-10-19RDMA/cma: Use output interface for net_dev checkHåkon Bugge
Commit 27cfde795a96 ("RDMA/cma: Fix arguments order in net device validation") swapped the src and dst addresses in the call to validate_net_dev(). As a consequence, the test in validate_ipv4_net_dev() to see if the net_dev is the right one, is incorrect for port 1 <-> 2 communication when the ports are on the same sub-net. This is fixed by denoting the flowi4_oif as the device instead of the incoming one. The bug has not been observed using IPv6 addresses.

Otherwise EINVAL is bogusly reported to userspace when deleting a set element. NFTA_SET_ELEM_KEY_END does not need to be set in case of: - insertion: if not present, start key is used as end key. - deletion: only start key needs to be specified, end key is ignored.

2022-10-19netfilter: rpfilter/fib: Set ->flowic_uid correctly for user namespaces.Guillaume Nault
Currently netfilter's rpfilter and fib modules implicitely initialise ->flowic_uid with 0. This is normally the root UID. However, this isn't the case in user namespaces, where user ID 0 is mapped to a different kernel UID. By initialising ->flowic_uid with sock_net_uid(), we get the root UID of the user namespace, thus keeping the same behaviour whether or not we're running in a user namepspace. Note, this is similar to commit 8bcfd0925ef1 ("ipv4: add missing initialization for flowi4_uid"), which fixed the rp_filter sysctl.

2022-10-18ionic: catch NULL pointer issue on reconfigBrett Creeley
It's possible that the driver will dereference a qcq that doesn't exist when calling ionic_reconfigure_queues(), which causes a page fault BUG. If a reduction in the number of queues is followed by a different reconfig such as changing the ring size, the driver can hit a NULL pointer when trying to clean up non-existent queues. Fix this by checking to make sure both the qcqs array and qcq entry exists bofore trying to use and free the entry.

2022-10-18drm/amdkfd: Fix type of reset_type parameter in hqd_destroy() callbackNathan Chancellor
When booting a kernel compiled with CONFIG_CFI_CLANG on a machine with an RX 6700 XT, there is a CFI failure in kfd_destroy_mqd_cp(): [ 12.894543] CFI failure at kfd_destroy_mqd_cp+0x2a/0x40 [amdgpu] (target: hqd_destroy_v10_3+0x0/0x260 [amdgpu]; expected type: 0x8594d794) Clang's kernel Control Flow Integrity (kCFI) makes sure that all indirect call targets have a type that exactly matches the function pointer prototype. In this case, hqd_destroy()'s third parameter, reset_type, should have a type of 'uint32_t' but every implementation of this callback has a third parameter type of 'enum kfd_preempt_type'. Update the function pointer prototype to match reality so that there is no more CFI violation.

2022-10-18dm verity: enable WQ_HIGHPRI on verify_wqNathan Huckleberry
WQ_HIGHPRI increases throughput and decreases disk latency when using dm-verity. This is important in Android for camera startup speed. The following tests were run by doing 60 seconds of random reads using a dm-verity device backed by two ramdisks. Without WQ_HIGHPRI lat (usec): min=13, max=3947, avg=69.53, stdev=50.55 READ: bw=51.1MiB/s (53.6MB/s), 51.1MiB/s-51.1MiB/s (53.6MB/s-53.6MB/s) With WQ_HIGHPRI: lat (usec): min=13, max=7854, avg=31.15, stdev=30.42 READ: bw=116MiB/s (121MB/s), 116MiB/s-116MiB/s (121MB/s-121MB/s) Further testing was done by measuring how long it takes to open a camera on an Android device. Without WQ_HIGHPRI Total verity work queue wait times (ms): 880.960, 789.517, 898.852 With WQ_HIGHPRI: Total verity work queue wait times (ms): 528.824, 439.191, 433.300 The average time to open the camera is reduced by 350ms (or 40-50%).
