[PATCH stable 0/6] net: dsa: b53: Correct learning for standalone ports

by Florian Fainelli

Hi Greg, Sasha, Jaakub and David, This patch series contains backports for a change that recently made it upstream as f9b3827ee66cfcf297d0acd6ecf33653a5f297ef ("net: dsa: b53: Support setting learning on port") however that commit depends on infrastructure that landed in v5.12-rc1. The way this was fixed in the netdev group's net tree is slightly different from how it should be backported to stable trees which is why you will find a patch for each branch in the thread started by this cover letter. The commit used as a Fixes: base dates back from when the driver was first introduced into the tree since this should have been fixed from day one ideally. Let me know if this does not apply for some reason. The changes from 4.9 through 4.19 are nearly identical and then from 5.4 through 5.11 are about the same. Thank you very much! -- 2.25.1

[PATCH for-stable-5.4] crypto: x86/aes-ni-xts - use direct calls to and 4-way stride

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> Upstream commit 86ad60a65f29dd862a11c22bb4b5be28d6c5cef1 The XTS asm helper arrangement is a bit odd: the 8-way stride helper consists of back-to-back calls to the 4-way core transforms, which are called indirectly, based on a boolean that indicates whether we are performing encryption or decryption. Given how costly indirect calls are on x86, let's switch to direct calls, and given how the 8-way stride doesn't really add anything substantial, use a 4-way stride instead, and make the asm core routine deal with any multiple of 4 blocks. Since 512 byte sectors or 4 KB blocks are the typical quantities XTS operates on, increase the stride exported to the glue helper to 512 bytes as well. As a result, the number of indirect calls is reduced from 3 per 64 bytes of in/output to 1 per 512 bytes of in/output, which produces a 65% speedup when operating on 1 KB blocks (measured on a Intel(R) Core(TM) i7-8650U CPU) Fixes: 9697fa39efd3f ("x86/retpoline/crypto: Convert crypto assembler indirect jumps") Tested-by: Eric Biggers <ebiggers(a)google.com> # x86_64 Signed-off-by: Ard Biesheuvel <ardb(a)kernel.org> Signed-off-by: Herbert Xu <herbert(a)gondor.apana.org.au> [ardb: rebase onto stable/linux-5.4.y] Signed-off-by: Ard Biesheuvel <ardb(a)kernel.org> --- Please apply on top of backports of 9c1e8836edbb crypto: x86 - Regularize glue function prototypes 032d049ea0f4 crypto: aesni - Use TEST %reg,%reg instead of CMP $0,%reg arch/x86/crypto/aesni-intel_asm.S | 115 ++++++++++++++++++----------- arch/x86/crypto/aesni-intel_glue.c | 25 ++++--- 2 files changed, 84 insertions(+), 56 deletions(-) diff --git a/arch/x86/crypto/aesni-intel_asm.S b/arch/x86/crypto/aesni-intel_asm.S index f10f044c887c..dd954d8db629 100644 --- a/arch/x86/crypto/aesni-intel_asm.S +++ b/arch/x86/crypto/aesni-intel_asm.S @@ -2726,25 +2726,18 @@ ENDPROC(aesni_ctr_enc) pxor CTR, IV;

But currently the USB-audio driver can't handle it because it has a check of shutdown flag for stopping the URBs. This is basically superfluous (the stopping URBs are safe at disconnection state), so let's drop the check.

[PATCH] RDMA/srp: Fix support for unpopulated and unbalanced NUMA nodes

by Yi Zhang

From: Nicolas Morey-Chaisemartin <nmoreychaisemartin(a)suse.com> This patch fixed one kernel NULL pointer issue with blktests srp/005 ---------- From: Nicolas Morey-Chaisemartin <nmoreychaisemartin(a)suse.com> commit 2b5715fc17386a6223490d5b8f08d031999b0c0b upstream. The current code computes a number of channels per SRP target and spreads them equally across all online NUMA nodes. Each channel is then assigned a CPU within this node. In the case of unbalanced, or even unpopulated nodes, some channels do not get a CPU associated and thus do not get connected. This causes the SRP connection to fail. This patch solves the issue by rewriting channel computation and allocation: - Drop channel to node/CPU association as it had no real effect on locality but added unnecessary complexity. - Tweak the number of channels allocated to reduce CPU contention when possible: - Up to one channel per CPU (instead of up to 4 by node) - At least 4 channels per node, unless ch_count module parameter is used.

[PATCH v2][for-stable-v5.11] arm64: Unconditionally set virtual cpu id registers

by Vladimir Murzin

Commit 78869f0f0552 ("arm64: Extract parts of el2_setup into a macro") reorganized el2 setup in such way that virtual cpu id registers set only in nVHE, yet they used (and need) to be set irrespective VHE support. Fixes: 78869f0f0552 ("arm64: Extract parts of el2_setup into a macro") Signed-off-by: Vladimir Murzin <vladimir.murzin(a)arm.com> --- Changelog v1 -> v2 - Drop the reference to 32bit guests from commit message (per Marc) There is no upstream fix since issue went away due to code there has been reworked in 5.12: nVHE comes first, so virtual cpu id register are always set.

The root cause is, we have the following bad loop of creating tons of system chunks: 1. The only SYSTEM chunk is being scrubbed It's very common to have only one SYSTEM chunk. 2. New SYSTEM bg will be allocated As btrfs_inc_block_group_ro() will check if we have enough space after marking current bg RO. If not, then allocate a new chunk. 3. New SYSTEM bg is still empty, will be reclaimed During the reclaim, we will mark it RO again. 4. That newly allocated empty SYSTEM bg get scrubbed We go back to step 2, as the bg is already mark RO but still not cleaned up yet. If the cleaner kthread doesn't get executed fast enough (e.g. only one CPU), then we will get more and more empty SYSTEM chunks, using up all the space of btrfs_super_block::sys_chunk_array. [FIX] Since scrub/dev-replace doesn't always need to allocate new extent, especially chunk tree extent, so we don't really need to do chunk pre-allocation. To break above spiral, here we introduce a new parameter to btrfs_inc_block_group(), @do_chunk_alloc, which indicates whether we need extra chunk pre-allocation. For relocation, we pass @do_chunk_alloc=true, while for scrub, we pass @do_chunk_alloc=false. This should keep unnecessary empty chunks from popping up for scrub. Also, since there are two parameters for btrfs_inc_block_group_ro(), add more comment for it.
