[ Upstream commit 4141b6a5 ] When perf record -e SF_CYCLES_BASIC_DIAG runs with very high frequency, the samples arrive faster than the perf process can save them to file. Eventually, for longer running processes, this leads to the siutation where the trace buffers allocated by perf slowly fills up. At one point the auxiliary trace buffer is full and the CPU Measurement sampling facility is turned off. Furthermore a warning is printed to the kernel log buffer: cpum_sf: The AUX buffer with 0 pages for the diagnostic-sampling mode is full The number of allocated pages for the auxiliary trace buffer is shown as zero pages. That is wrong. Fix this by saving the number of allocated pages before entering the work loop in the interrupt handler. When the interrupt handler processes the samples, it may detect the buffer full condition and stop sampling, reducing the buffer size to zero. Print the correct value in the error message: cpum_sf: The AUX buffer with 256 pages for the diagnostic-sampling mode is full Signed-off-by:

[ Upstream commit af6cf95c ] When building ppc64 defconfig, Clang errors (trimmed for brevity): arch/powerpc/platforms/maple/setup.c:365:1: error: attribute declaration must precede definition [-Werror,-Wignored-attributes] machine_device_initcall(maple, maple_cpc925_edac_setup); ^ machine_device_initcall expands to __define_machine_initcall, which in turn has the macro machine_is used in it, which declares mach_##name with an __attribute__((weak)). define_machine actually defines mach_##name, which in this file happens before the declaration, hence the warning. To fix this, move define_machine after machine_device_initcall so that the declaration occurs before the definition, which matches how machine_device_initcall and define_machine work throughout arch/powerpc. While we're here, remove some spaces before tabs. Fixes: 8f101a05 ("edac: cpc925 MC platform device setup") Reported-by:

[ Upstream commit 8605cf0e ] When dreq is allocated by nfs_direct_req_alloc(), dreq->kref is initialized to 2. Therefore we need to call nfs_direct_req_release() twice to release the allocated dreq. Usually it is called in nfs_file_direct_{read, write}() and nfs_direct_complete(). However, current code only calls nfs_direct_req_relese() once if nfs_get_lock_context() fails in nfs_file_direct_{read, write}(). So, that case would result in memory leak. Fix this by adding the missing call. Signed-off-by:

[ Upstream commit b0ecf1c6 ] clk_hw_round_rate() may call round rate function of its parents. In case of SAM9X60 two of USB parrents are PLLA and UPLL. These clocks are controlled by clk-sam9x60-pll.c driver. The round rate function for this driver is sam9x60_pll_round_rate() which call in turn sam9x60_pll_get_best_div_mul(). In case the requested rate is not in the proper range (rate < characteristics->output[0].min && rate > characteristics->output[0].max) the sam9x60_pll_round_rate() will return a negative number to its caller (called by clk_core_round_rate_nolock()). clk_hw_round_rate() will return zero in case a negative number is returned by clk_core_round_rate_nolock(). With this, the USB clock will continue its rate computation even caller of clk_hw_round_rate() returned an error. With this, the USB clock on SAM9X60 may not chose the best parent. I detected this after a suspend/resume cycle on SAM9X60. Signed-off-by:

[ Upstream commit 74347a99 ] When kdump is not configured, a Hyper-V VM might still respond to network traffic after a kernel panic when kernel parameter panic=0. The panic CPU goes into an infinite loop with interrupts enabled, and the VMbus driver interrupt handler still works because the VMbus connection is unloaded only in the kdump path. The network responses make the other end of the connection think the VM is still functional even though it has panic'ed, which could affect any failover actions that should be taken. Fix this by unloading the VMbus connection during the panic process. vmbus_initiate_unload() could then be called twice (e.g., by hyperv_panic_event() and hv_crash_handler(), so reset the connection state in vmbus_initiate_unload() to ensure the unload is done only once.

[ Upstream commit 952c48b0 ] rbd_dev_unprobe() is supposed to undo most of rbd_dev_image_probe(), including rbd_dev_header_info(), which means that rbd_dev_header_info() isn't supposed to be called after rbd_dev_unprobe(). However, rbd_dev_image_release() calls rbd_dev_unprobe() before rbd_unregister_watch(). This is racy because a header update notify can sneak in: "rbd unmap" thread ceph-watch-notify worker rbd_dev_image_release() rbd_dev_unprobe() free and zero out header rbd_watch_cb() rbd_dev_refresh() rbd_dev_header_info() read in header The same goes for "rbd map" because rbd_dev_image_probe() calls rbd_dev_unprobe() on errors.

[ Upstream commit 0e4e1de5 ] rbd_unregister_watch() flushes notifies and therefore cannot be called under header_rwsem because a header update notify takes header_rwsem to synchronize with "rbd map". If mapping an image fails after the watch is established and a header update notify sneaks in, we deadlock when erroring out from rbd_dev_image_probe(). Move watch registration and unregistration out of the critical section. The only reason they were put there was to make header_rwsem management slightly more obvious.

commit bb9562cf upstream. The current arm BPF JIT does not correctly compile RSH or ARSH when the immediate shift amount is 0. This causes the "rsh64 by 0 imm" and "arsh64 by 0 imm" BPF selftests to hang the kernel by reaching an instruction the verifier determines to be unreachable. The root cause is in how immediate right shifts are encoded on arm. For LSR and ASR (logical and arithmetic right shift), a bit-pattern of 00000 in the immediate encodes a shift amount of 32. When the BPF immediate is 0, the generated code shifts by 32 instead of the expected behavior (a no-op). This patch fixes the bugs by adding an additional check if the BPF immediate is 0. After the change, the above mentioned BPF selftests pass. Fixes: 39c13c20 ("arm: eBPF JIT compiler") Co-developed-by:

commit d87f6392 upstream. Since commit a8ac900b ("ext4: use non-movable memory for the superblock") buffers for ext4 superblock were allocated using the sb_bread_unmovable() helper which allocated buffer heads out of non-movable memory blocks. It was necessarily to not block page migrations and do not cause cma allocation failures. However commit 85c8f176 ("ext4: preload block group descriptors") broke this by introducing pre-reading of the ext4 superblock. The problem is that __breadahead() is using __getblk() underneath, which allocates buffer heads out of movable memory. It resulted in page migration failures I've seen on a machine with an ext4 partition and a preallocated cma area. Fix this by introducing sb_breadahead_unmovable() and __breadahead_gfp() helpers which use non-movable memory for buffer head allocations and use them for the ext4 superblock readahead. Reviewed-by:

commit 4178417c upstream. This patch fixes an incorrect check in how immediate memory offsets are computed for BPF_DW on arm. For BPF_LDX/ST/STX + BPF_DW, the 32-bit arm JIT breaks down an 8-byte access into two separate 4-byte accesses using off+0 and off+4. If off fits in imm12, the JIT emits a ldr/str instruction with the immediate and avoids the use of a temporary register. While the current check off <= 0xfff ensures that the first immediate off+0 doesn't overflow imm12, it's not sufficient for the second immediate off+4, which may cause the second access of BPF_DW to read/write the wrong address. This patch fixes the problem by changing the check to off <= 0xfff - 4 for BPF_DW, ensuring off+4 will never overflow. A side effect of simplifying the check is that it now allows using negative immediate offsets in ldr/str. This means that small negative offsets can also avoid the use of a temporary register. This patch introduces no new failures in test_verifier or test_bpf.c.
