2022-10-19nvme-apple: don't limit DMA segement sizeRussell King (Oracle)
NVMe uses PRPs for data transfers and has no specific limit for a single DMA segement. Limiting the size will cause problems because the block layer assumes PRP-ish devices using a virt boundary mask don't have a segment limit. And while this is true, we also really need to tell the DMA mapping layer about it, otherwise dma-debug will trip over it.

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. Hence, relax the sanity check. Fixes: 88cccd908d51 ("netfilter: nf_tables: NFTA_SET_ELEM_KEY_END requires concat and interval flags") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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.

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%).

2022-10-18x86/resctrl: Fix min_cbm_bits for AMDBabu Moger
AMD systems support zero CBM (capacity bit mask) for cache allocation. That is reflected in rdt_init_res_defs_amd() by: r->cache.arch_has_empty_bitmaps = true; However given the unified code in cbm_validate(), checking for: val == 0 && !arch_has_empty_bitmaps is not enough because of another check in cbm_validate(): if ((zero_bit - first_bit) < r->cache.min_cbm_bits) The default value of r->cache.min_cbm_bits = 1. Leading to: $ cd /sys/fs/resctrl $ mkdir foo $ cd foo $ echo L3:0=0 > schemata -bash: echo: write error: Invalid argument $ cat /sys/fs/resctrl/info/last_cmd_status Need at least 1 bits in the mask Initialize the min_cbm_bits to 0 for AMD. Also, remove the default setting of min_cbm_bits and initialize it separately. After the fix: $ cd /sys/fs/resctrl $ mkdir foo $ cd foo $ echo L3:0=0 > schemata $ cat /sys/fs/resctrl/info/last_cmd_status ok Fixes: 316e7f901f5a ("x86/resctrl: Add struct rdt_cache::arch_has_{sparse, empty}_bitmaps") Co-developed-by: Stephane Eranian <eranian@google.com> Signed-off-by: Stephane Eranian <eranian@google.com> Signed-off-by: Babu Moger <babu.moger@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de> Reviewed-by: Ingo Molnar <mingo@kernel.org> Reviewed-by: James Morse <james.morse@arm.com> Reviewed-by: Reinette Chatre <reinette.chatre@intel.com> Reviewed-by: Fenghua Yu <fenghua.yu@intel.com> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/lkml/20220517001234.3137157-1-eranian@google.com

2022-10-18dm bufio: use the acquire memory barrier when testing for B_READINGMikulas Patocka
The function test_bit doesn't provide any memory barrier. It may be possible that the read requests that follow test_bit(B_READING, &b->state) are reordered before the test, reading invalid data that existed before B_READING was cleared. Fix this bug by changing test_bit to test_bit_acquire. This is particularly important on arches with weak(er) memory ordering (e.g. arm64).
