2020-08-21afs: Fix NULL deref in afs_dynroot_depopulate()David Howells1-9/+11
If an error occurs during the construction of an afs superblock, it's possible that an error occurs after a superblock is created, but before we've created the root dentry. If the superblock has a dynamic root (ie. what's normally mounted on /afs), the afs_kill_super() will call afs_dynroot_depopulate() to unpin any created dentries - but this will oops if the root hasn't been created yet. Fix this by skipping that bit of code if there is no root dentry. This leads to an oops looking like: general protection fault, ... KASAN: null-ptr-deref in range [0x0000000000000068-0x000000000000006f] ... RIP: 0010:afs_dynroot_depopulate+0x25f/0x529 fs/afs/dynroot.c:385 ...

2020-08-20RDMA/hfi1: Correct an interlock issue for TID RDMA WRITE requestKaike Wan1-0/+1
The following message occurs when running an AI application with TID RDMA enabled: hfi1 0000:7f:00.0: hfi1_0: [QP74] hfi1_tid_timeout 4084 hfi1 0000:7f:00.0: hfi1_0: [QP70] hfi1_tid_timeout 4084 The issue happens when TID RDMA WRITE request is followed by an IB_WR_RDMA_WRITE_WITH_IMM request, the latter could be completed first on the responder side. As a result, no ACK packet for the latter could be sent because the TID RDMA WRITE request is still being processed on the responder side. When the TID RDMA WRITE request is eventually completed, the requester will wait for the IB_WR_RDMA_WRITE_WITH_IMM request to be acknowledged. If the next request is another TID RDMA WRITE request, no TID RDMA WRITE DATA packet could be sent because the preceding IB_WR_RDMA_WRITE_WITH_IMM request is not completed yet. Consequently the IB_WR_RDMA_WRITE_WITH_IMM will be retried but it will be ignored on the responder side because the responder thinks it has already been completed. Eventually the retry will be exhausted and the qp will be put into error state on the requester side. On the responder side, the TID resource timer will eventually expire because no TID RDMA WRITE DATA packets will be received for the second TID RDMA WRITE request. There is also risk of a write-after-write memory corruption due to the issue. Fix by adding a requester side interlock to prevent any potential data corruption and TID RDMA protocol error.

2020-08-19lib/string.c: Use freestanding environmentArvind Sankar1-1/+6
gcc can transform the loop in a naive implementation of memset/memcpy etc into a call to the function itself. This optimization is enabled by -ftree-loop-distribute-patterns. This has been the case for a while, but gcc-10.x enables this option at -O2 rather than -O3 as in previous versions. Add -ffreestanding, which implicitly disables this optimization with gcc. It is unclear whether clang performs such optimizations, but hopefully it will also not do so in a freestanding environment.

2020-08-19x86/boot/compressed: Use builtin mem functions for decompressorArvind Sankar2-9/+3
Since commits c041b5ad8640 ("x86, boot: Create a separate string.h file to provide standard string functions") fb4cac573ef6 ("x86, boot: Move memcmp() into string.h and string.c") the decompressor stub has been using the compiler's builtin memcpy, memset and memcmp functions, _except_ where it would likely have the largest impact, in the decompression code itself. Remove the #undef's of memcpy and memset in misc.c so that the decompressor code also uses the compiler builtins. The rationale given in the comment doesn't really apply: just because some functions use the out-of-line version is no reason to not use the builtin version in the rest. Replace the comment with an explanation of why memzero and memmove are being #define'd. Drop the suggestion to #undef in boot/string.h as well: the out-of-line versions are not really optimized versions, they're generic code that's good enough for the preboot environment. The compiler will likely generate better code for constant-size memcpy/memset/memcmp if it is allowed to. Most decompressors' performance is unchanged, with the exception of LZ4 and 64-bit ZSTD. Before After ARCH LZ4 73ms 10ms 32 LZ4 120ms 10ms 64 ZSTD 90ms 74ms 64 Measurements on QEMU on 2.2GHz Broadwell Xeon, using defconfig kernels. Decompressor code size has small differences, with the largest being that 64-bit ZSTD decreases just over 2k. The largest code size increase was on 64-bit XZ, of about 400 bytes.

2020-08-19ext4: limit the length of per-inode prealloc listbrookxu13-29/+104
In the scenario of writing sparse files, the per-inode prealloc list may be very long, resulting in high overhead for ext4_mb_use_preallocated(). To circumvent this problem, we limit the maximum length of per-inode prealloc list to 512 and allow users to modify it. After patching, we observed that the sys ratio of cpu has dropped, and the system throughput has increased significantly. We created a process to write the sparse file, and the running time of the process on the fixed kernel was significantly reduced, as follows: Running time on unfixed kernel： [root@TENCENT64 ~]# time taskset 0x01 ./sparse /data1/sparce.dat real 0m2.051s user 0m0.008s sys 0m2.026s Running time on fixed kernel： [root@TENCENT64 ~]# time taskset 0x01 ./sparse /data1/sparce.dat real 0m0.471s user 0m0.004s sys 0m0.395s Signed-off-by: Chunguang Xu <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Theodore Ts'o <[email protected]>

2020-08-19ALSA: hda: avoid reset of sdo_limitSameer Pujar2-11/+12
By default 'sdo_limit' is initialized with a default value of '8' as per spec. This is overridden in cases where a different value is required. However this is getting reset when snd_hdac_bus_init_chip() is called again, which happens during runtime PM cycle. Avoid this reset by moving 'sdo_limit' setup to 'snd_hdac_bus_init()' function which would be called only once.

2020-08-19drm/i915/tgl: Make sure TC-cold is blocked before enabling TC AUX power wellsImre Deak1-6/+6
The dependency between power wells is determined by the ordering of the power well list: when enabling the power wells for a domain, this happens walking the power well list forward, while disabling them happens in the reverse direction. Accordingly a power well on the list must follow any other power well it depends on. Since the TC AUX power wells depend on TC-cold being blocked, move the TC-cold off power well before all AUX power wells.

2020-08-19drm/i915/selftests: Avoid passing a random 0 into ilog2George Spelvin1-8/+10
igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number s>>12. Once in 2 million seeds, this is zero and ilog2 summons the nasal demons. There was an attempt to handle this case with a max(), but that's too late; ms could already be something bizarre. Given that the low 12 bits of s and ms are always zero, it's a lot simpler just to divide them by 4096, then everything fits into 32 bits, and we can easily generate a random number 1 <= s <= 0x1fffff.
