[REGRESSION 6.1.70] system calls with CIFS mounts failing with "Resource temporarily unavailable"

by Leonardo Brondani Schenkel

I'm new here, first time reporting a regression, apologies in advance if I'm doing something wrong of if this was already reported (I found some CIFS issues but not exactly this one). I'm using x86-64 Arch Linux and LTS kernel (6.1.71 as I write this) and I noticed a regression that I could reproduce in other boxes with other architectures as well (aarch64 with 6.1.70). # mount.cifs //server/share /mnt # mount //server/share on /mnt type cifs (rw,relatime,vers=3.1.1...) # cd /mnt # df . df: .: Resource temporarily unavailable # ls -al ls: .: Resource temporarily unavailable ls: file1: Resource temporarily unavailable ls: file2: Resource temporarily unavailable [...then ls shows the listing...] If I use strace with df, the problem is: statfs(".", 0x.....) = -1 EAGAIN (Resource temporarily unavailable) And with ls: listxattr(".", 0x..., 152): -1 EAGAIN (Resource temporarily unavailable) listxattr("file1", ..., 152): -1 EAGAIN (same as above) ... Initially I thought the problem was with the Samba server and/or the client mount flags, but I've spent a day trying a *lot* of different combinations and nothing worked. This happens with any share that I try, and I've tried mounting shares from multiple Linux boxes running different Samba and kernel versions. Then I tried changing kernel versions at my client box. I booted latest 6.6.9 and the problem simply disappeared. My Debian server with 6.5.11 also doesn't have it. I then started a VM and tried a "bisection" of 6.1.x versions, leading to kernel 6.1.70 when this started to happen. 6.1.69 and older look fine. I hope that this is enough information to reproduce this issue. I will be glad to provide more info if necessary. // Leonardo.

[PATCH AUTOSEL 6.1 01/27] PCI: Only override AMD USB controller if required

by Sasha Levin

From: "Guilherme G. Piccoli" <gpiccoli(a)igalia.com> [ Upstream commit e585a37e5061f6d5060517aed1ca4ccb2e56a34c ] By running a Van Gogh device (Steam Deck), the following message was noticed in the kernel log: pci 0000:04:00.3: PCI class overridden (0x0c03fe -> 0x0c03fe) so dwc3 driver can claim this instead of xhci Effectively this means the quirk executed but changed nothing, since the class of this device was already the proper one (likely adjusted by newer firmware versions).

[PATCH 0/2] RISC-V: Fix CONFIG_AS_HAS_OPTION_ARCH with tip of tree LLVM

by Nathan Chancellor

Hi all, Eric reported that builds of LLVM with [1] (close to tip of tree) have CONFIG_AS_HAS_OPTION_ARCH=n because the test for expected failure on invalid input has started succeeding. This Kconfig test was added because '.option arch' only causes an assembler warning when it is unsupported, rather than a hard error, which is what users of as-instr expect when something is unsupported. This can be resolved by turning assembler warnings into errors with '-Wa,--fatal-warnings' like we do with the compiler with '-Werror', which is what the first patch does. The second patch removes the invalid test, as the valid test is good enough with fatal warnings. I have diffed several configurations for the different architectures that use as-instr and I have found no issues. I think this could go in through either the kbuild or RISC-V tree with sufficient acks but I will let them fight over who takes it :) [1]: https://github.com/llvm/llvm-project/commit/3ac9fe69f70a2b3541266daedbaaa7d… --- Nathan Chancellor (2): kbuild: Add -Wa,--fatal-warnings to as-instr invocation RISC-V: Drop invalid test from CONFIG_AS_HAS_OPTION_ARCH arch/riscv/Kconfig | 1 - scripts/Kconfig.include | 2 +- scripts/Makefile.compiler | 2 +- 3 files changed, 2 insertions(+), 3 deletions(-) --- base-commit: 6613476e225e090cc9aad49be7fa504e290dd33d change-id: 20240124-fix-riscv-option-arch-llvm-18-3cbe7b09a216 Best regards, -- Nathan Chancellor <nathan(a)kernel.org>

[PATCH 4/4] mtd: rawnand: Clarify conditions to enable continuous reads

by Miquel Raynal

The current logic is probably fine but is a bit convoluted. Plus, we don't want partial pages to be part of the sequential operation just in case the core would optimize the page read with a subpage read (which would break the sequence). This may happen on the first and last page only, so if the start offset or the end offset is not aligned with a page boundary, better avoid them to prevent any risk.

[PATCH] x86/barrier: Do not serialize MSR accesses on AMD

by Kishon Vijay Abraham I

From: "Borislav Petkov (AMD)" <bp(a)alien8.de> commit 04c3024560d3a14acd18d0a51a1d0a89d29b7eb5 upstream. AMD does not have the requirement for a synchronization barrier when acccessing a certain group of MSRs. Do not incur that unnecessary penalty there. There will be a CPUID bit which explicitly states that a MFENCE is not needed. Once that bit is added to the APM, this will be extended with it. While at it, move to processor.h to avoid include hell. Untangling that file properly is a matter for another day. Some notes on the performance aspect of why this is relevant, courtesy of Kishon VijayAbraham <Kishon.VijayAbraham(a)amd.com>: On a AMD Zen4 system with 96 cores, a modified ipi-bench[1] on a VM shows x2AVIC IPI rate is 3% to 4% lower than AVIC IPI rate. The ipi-bench is modified so that the IPIs are sent between two vCPUs in the same CCX. This also requires to pin the vCPU to a physical core to prevent any latencies. This simulates the use case of pinning vCPUs to the thread of a single CCX to avoid interrupt IPI latency. In order to avoid run-to-run variance (for both x2AVIC and AVIC), the below configurations are done: 1) Disable Power States in BIOS (to prevent the system from going to lower power state) 2) Run the system at fixed frequency 2500MHz (to prevent the system from increasing the frequency when the load is more) With the above configuration: *) Performance measured using ipi-bench for AVIC: Average Latency: 1124.98ns [Time to send IPI from one vCPU to another vCPU] Cumulative throughput: 42.6759M/s [Total number of IPIs sent in a second from 48 vCPUs simultaneously] *) Performance measured using ipi-bench for x2AVIC: Average Latency: 1172.42ns [Time to send IPI from one vCPU to another vCPU] Cumulative throughput: 40.9432M/s [Total number of IPIs sent in a second from 48 vCPUs simultaneously] From above, x2AVIC latency is ~4% more than AVIC. However, the expectation is x2AVIC performance to be better or equivalent to AVIC. Upon analyzing the perf captures, it is observed significant time is spent in weak_wrmsr_fence() invoked by x2apic_send_IPI(). With the fix to skip weak_wrmsr_fence() *) Performance measured using ipi-bench for x2AVIC: Average Latency: 1117.44ns [Time to send IPI from one vCPU to another vCPU] Cumulative throughput: 42.9608M/s [Total number of IPIs sent in a second from 48 vCPUs simultaneously] Comparing the performance of x2AVIC with and without the fix, it can be seen the performance improves by ~4%. Performance captured using an unmodified ipi-bench using the 'mesh-ipi' option with and without weak_wrmsr_fence() on a Zen4 system also showed significant performance improvement without weak_wrmsr_fence(). The 'mesh-ipi' option ignores CCX or CCD and just picks random vCPU. Average throughput (10 iterations) with weak_wrmsr_fence(), Cumulative throughput: 4933374 IPI/s Average throughput (10 iterations) without weak_wrmsr_fence(), Cumulative throughput: 6355156 IPI/s [1] https://github.com/bytedance/kvm-utils/tree/master/microbenchmark/ipi-bench Cc: stable(a)vger.kernel.org # 6.6+ Signed-off-by: Borislav Petkov (AMD) <bp(a)alien8.de> Link: https://lore.kernel.org/r/20230622095212.20940-1-bp@alien8.de Signed-off-by: Kishon Vijay Abraham I <kvijayab(a)amd.com> --- Kindly merge this patch to stable releases (v6.6+) as it's a perf optimization.

We can trigger a slab-out-of-bounds with the following commands: mkfs.ext4 -F /dev/$disk 10G mount /dev/$disk /tmp/test echo 2147483647 > /sys/fs/ext4/$disk/mb_group_prealloc echo test > /tmp/test/file && sync ================================================================== BUG: KASAN: slab-out-of-bounds in ext4_mb_find_good_group_avg_frag_lists+0x8a/0x200 [ext4] Read of size 8 at addr ffff888121b9d0f0 by task kworker/u2:0/11 CPU: 0 PID: 11 Comm: kworker/u2:0 Tainted: GL 6.7.0-next-20240118 #521 Call Trace: dump_stack_lvl+0x2c/0x50 kasan_report+0xb6/0xf0 ext4_mb_find_good_group_avg_frag_lists+0x8a/0x200 [ext4] ext4_mb_regular_allocator+0x19e9/0x2370 [ext4] ext4_mb_new_blocks+0x88a/0x1370 [ext4] ext4_ext_map_blocks+0x14f7/0x2390 [ext4] ext4_map_blocks+0x569/0xea0 [ext4] ext4_do_writepages+0x10f6/0x1bc0 [ext4] [...] ================================================================== The flow of issue triggering is as follows: // Set s_mb_group_prealloc to 2147483647 via sysfs ext4_mb_new_blocks ext4_mb_normalize_request ext4_mb_normalize_group_request ac->ac_g_ex.fe_len = EXT4_SB(sb)->s_mb_group_prealloc ext4_mb_regular_allocator ext4_mb_choose_next_group ext4_mb_choose_next_group_best_avail mb_avg_fragment_size_order order = fls(len) - 2 = 29 ext4_mb_find_good_group_avg_frag_lists frag_list = &sbi->s_mb_avg_fragment_size[order] if (list_empty(frag_list)) // Trigger SOOB! At 4k block size, the length of the s_mb_avg_fragment_size list is 14, but an oversized s_mb_group_prealloc is set, causing slab-out-of-bounds to be triggered by an attempt to access an element at index 29. Therefore it is not allowed to set s_mb_group_prealloc to a value greater than s_clusters_per_group via sysfs, and to avoid returning an order from mb_avg_fragment_size_order() that is greater than MB_NUM_ORDERS(sb).

xfrm: Remove inner/outer modes from input/output path

by Sri Sakthi

Hi, Below 2 xfrm ipsec related commits have already been merged to mainline. From Herbert Xu. Description: Remove inner/outer modes from input/output path. These are not needed anymore. xfrm: Remove inner/outer modes from output path (commit: f4796398f21b9844017a2dac883b1dd6ad6edd60) xfrm: Remove inner/outer modes from input path (commit: 5f24f41e8ea62a6a9095f9bbafb8b3aebe265c68) Reason for backporting – We have transport mode interleaved with tunnel mode support as part of ipsec with compression offering. These commits in v6.1 LTS would help. Requesting to apply these commits to Kernel LTS version 6.1. Thanks, Srisakthi S

[PATCH stable] mptcp: introduce explicit flag for first subflow disposal

by Christoph Paasch

From: Paolo Abeni <pabeni(a)redhat.com> This is a partial backport of the upstram commit 39880bd808ad ("mptcp: get rid of msk->subflow"). It's partial to avoid a long a complex dependency chain not suitable for stable. The only bit remaning from the original commit is the introduction of a new field avoid a race at close time causing an UaF: BUG: KASAN: use-after-free in mptcp_subflow_queue_clean+0x2c9/0x390
