2023-02-08arm64: dts: qcom: msm8996 switch from RPM_SMD_BB_CLK1 to RPM_SMD_XO_CLK_SRCDmitry Baryshkov
The vendor kernel uses RPM_SMD_XO_CLK_SRC clock as an CXO clock rather than using the RPM_SMD_BB_CLK1 directly. Follow this example and switch msm8996.dtsi to use RPM_SMD_XO_CLK_SRC clock instead of RPM_SMB_BB_CLK1.

2023-02-08md: account io_acct_set usage with active_ioXiao Ni
io_acct_set was enabled for raid0/raid5 io accounting. bios that contain md_io_acct are allocated in the i/o path. There isn't a good method to monitor if these bios are all finished and freed. In the takeover process, io_acct_set (which is used for bios with md_io_acct) need to be freed. However, if some bios finish after io_acct_set is freed, it may trigger the following panic: [ 6973.767999] RIP: 0010:mempool_free+0x52/0x80 [ 6973.786098] Call Trace: [ 6973.786549] md_end_io_acct+0x31/0x40 [ 6973.787227] blk_update_request+0x224/0x380 [ 6973.787994] blk_mq_end_request+0x1a/0x130 [ 6973.788739] blk_complete_reqs+0x35/0x50 [ 6973.789456] __do_softirq+0xd7/0x2c8 [ 6973.790114] ? sort_range+0x20/0x20 [ 6973.790763] run_ksoftirqd+0x2a/0x40 [ 6973.791400] smpboot_thread_fn+0xb5/0x150 [ 6973.792114] kthread+0x10b/0x130 [ 6973.792724] ? set_kthread_struct+0x50/0x50 [ 6973.793491] ret_from_fork+0x1f/0x40 Fix this by increasing and decreasing active_io for each bio with md_io_acct so that mddev_suspend() will wait until all bios from io_acct_set finish before freeing io_acct_set.

Add option to set when the perf buffer should wake up, by default the perf buffer becomes signaled for every event that is being pushed to it.

2023-02-08randstruct: disable Clang 15 supportEric Biggers
The randstruct support released in Clang 15 is unsafe to use due to a bug that can cause miscompilations: "-frandomize-layout-seed inconsistently randomizes all-function-pointers structs" (https://github.com/llvm/llvm-project/issues/60349).

2023-02-08uaccess: Add minimum bounds check on kernel buffer sizeKees Cook
While there is logic about the difference between ksize and usize, copy_struct_from_user() didn't check the size of the destination buffer (when it was known) against ksize. Add this check so there is an upper bounds check on the possible memset() call, otherwise lower bounds checks made by callers will trigger bounds warnings under -Warray-bounds.

GCC does not like having a partially allocated object, since it cannot reason about it for bounds checking when it is passed to other code. Instead, fully allocate sig_inputArgs.

Fix by replacing the unsigned 'immediate.bytes' (plus a cast) with the signed 'immediate.value' when assigning to the relative jump offset.

2023-02-08bpf/docs: Update design QA to be consistent with kfunc lifecycle docsToke Høiland-Jørgensen
Cong pointed out that there are some inconsistencies between the BPF design QA and the lifecycle expectations documentation we added for kfuncs. Let's update the QA file to be consistent with the kfunc docs, and add references where it makes sense. Also document that modules may export kfuncs now. v3: - Grammar nit + ack from David v2: - Fix repeated word (s/defined defined/defined/) Reported-by: Cong Wang <xiyou.wangcong@gmail.com> Acked-by: David Vernet <void@manifault.com> Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/r/20230208164143.286392-1-toke@redhat.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2023-02-08EDAC/i10nm: Add driver decoder for Sapphire Rapids serverYouquan Song
Intel SDM (December 2022) vol3B 17.13.2 contains IMC MC error codes for Sapphire Rapids. Current i10nm_edac only supports firmware decoder (ACPI DSM methods) for Sapphire Rapids. So add the driver decoder (decoding DDR memory errors via extracting error information from the IMC MC error codes) for Sapphire Rapids for better decoding performance.

2023-02-08Merge branch 'taprio-auto-qmaxsdu-new-tx'David S. Miller
Vladimir Oltean says: ==================== taprio automatic queueMaxSDU and new TXQ selection procedure This patch set addresses 2 design limitations in the taprio software scheduler: 1. Software scheduling fundamentally prioritizes traffic incorrectly, in a way which was inspired from Intel igb/igc drivers and does not follow the inputs user space gives (traffic classes and TC to TXQ mapping). Patch 05/15 handles this, 01/15 - 04/15 are preparations for this work. 2. Software scheduling assumes that the gate for a traffic class closes as soon as the next interval begins. But this isn't true. If consecutive schedule entries have that traffic class gate open, there is no "gate close" event and taprio should keep dequeuing from that TC without interruptions. Patches 06/15 - 15/15 handle this. Patch 10/15 is a generic Qdisc change required for this to work. Future development directions which depend on this patch set are: - Propagating the automatic queueMaxSDU calculation down to offloading device drivers, instead of letting them calculate this, as vsc9959_tas_guard_bands_update() does today. - A software data path for tc-taprio with preemptible traffic and Hold/Release events. v1 at: https://patchwork.kernel.org/project/netdevbpf/cover/20230128010719.2182346-1-vladimir.oltean@nxp.com/ ==================== Signed-off-by: David S.

2023-02-08net/sched: taprio: don't segment unnecessarilyVladimir Oltean
Improve commit 497cc00224cf ("taprio: Handle short intervals and large packets") to only perform segmentation when skb->len exceeds what taprio_dequeue() expects. In practice, this will make the biggest difference when a traffic class gate is always open in the schedule. This is because the max_frm_len will be U32_MAX, and such large skb->len values as Kurt reported will be sent just fine unsegmented. What I don't seem to know how to handle is how to make sure that the segmented skbs themselves are smaller than the maximum frame size given by the current queueMaxSDU[tc]. Nonetheless, we still need to drop those, otherwise the Qdisc will hang.

2023-02-08net/sched: taprio: split segmentation logic from qdisc_enqueue()Vladimir Oltean
The majority of the taprio_enqueue()'s function is spent doing TCP segmentation, which doesn't look right to me. Compilers shouldn't have a problem in inlining code no matter how we write it, so move the segmentation logic to a separate function.
