2022-10-07wifi: mac80211: remove/avoid misleading printsJames Prestwood
At some point a few kernel debug prints started appearing which indicated something was sending invalid IEs: "bad VHT capabilities, disabling VHT" "Invalid HE elem, Disable HE" Turns out these were being printed because the local hardware supported HE/VHT but the peer/AP did not. Bad/invalid indicates, to me at least, that the IE is in some way malformed, not missing. For the HE print (ieee80211_verify_peer_he_mcs_support) it will now silently fail if the HE capability element is missing (still prints if the element size is wrong). For the VHT print, it has been removed completely and will silently set the DISABLE_VHT flag which is consistent with how DISABLE_HT is set.

2022-10-07wifi: mac80211: fix probe req HE capabilities accessJames Prestwood
When building the probe request IEs HE support is checked for the 6GHz band (wiphy->bands[NL80211_BAND_6GHZ]). If supported the HE capability IE should be included according to the spec. The problem is the 16-bit capability is obtained from the band object (sband) that was passed in, not the 6GHz band object (sband6). If the sband object doesn't support HE it will result in a warning.

2022-10-07net/9p: use a dedicated spinlock for trans_fdDominique Martinet
Shamelessly copying the explanation from Tetsuo Handa's suggested patch[1] (slightly reworded): syzbot is reporting inconsistent lock state in p9_req_put()[2], for p9_tag_remove() from p9_req_put() from IRQ context is using spin_lock_irqsave() on "struct p9_client"->lock but trans_fd (not from IRQ context) is using spin_lock(). Since the locks actually protect different things in client.c and in trans_fd.c, just replace trans_fd.c's lock by a new one specific to the transport (client.c's protect the idr for fid/tag allocations, while trans_fd.c's protects its own req list and request status field that acts as the transport's state machine) Link: https://lore.kernel.org/r/20220904112928.1308799-1-asmadeus@codewreck.org Link: https://lkml.kernel.org/r/2470e028-9b05-2013-7198-1fdad071d999@I-love.SAKURA.ne.jp [1] Link: https://syzkaller.appspot.com/bug?extid=2f20b523930c32c160cc [2] Reported-by: syzbot <syzbot+2f20b523930c32c160cc@syzkaller.appspotmail.com> Reported-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Reviewed-by: Christian Schoenebeck <linux_oss@crudebyte.com> Signed-off-by: Dominique Martinet <asmadeus@codewreck.org>

Actual clk rate may not be the same as the requested clk frequency depending on the parent clock source set.

2022-10-07mmc: renesas_sdhi: Fix rounding errorsBiju Das
Due to clk rounding errors on RZ/G2L platforms, it selects a clock source with a lower clock rate compared to a higher one. For eg: The rounding error (533333333 Hz / 4 * 4 = 533333332 Hz < 5333333 33 Hz) selects a clk source of 400 MHz instead of 533.333333 MHz.

2022-10-07xen/pcifront: move xenstore config scanning into sub-functionJuergen Gross
pcifront_try_connect() and pcifront_attach_devices() share a large chunk of duplicated code for reading the config information from Xenstore, which only differs regarding calling pcifront_rescan_root() or pcifront_scan_root(). Put that code into a new sub-function. It is fine to always call pcifront_rescan_root() from that common function, as it will fallback to pcifront_scan_root() if the domain/bus combination isn't known yet (and pcifront_scan_root() should never be called for an already known domain/bus combination anyway). In order to avoid duplicate messages for the fallback case move the check for domain/bus not known to the beginning of pcifront_rescan_root(). While at it fix the error reporting in case the root-xx node had the wrong format. As the return value of pcifront_try_connect() and pcifront_attach_devices() are not used anywhere make those functions return void. As an additional bonus this removes the dubious return of -EFAULT in case of an unexpected driver state.

2022-10-06riscv: enable THP_SWAP for RV64Jisheng Zhang
I have a Sipeed Lichee RV dock board which only has 512MB DDR, so memory optimizations such as swap on zram are helpful. As is seen in commit d0637c505f8a ("arm64: enable THP_SWAP for arm64") and commit bd4c82c22c367e ("mm, THP, swap: delay splitting THP after swapped out"), THP_SWAP can improve the swap throughput significantly.

2022-10-079p/trans_fd: always use O_NONBLOCK read/writeTetsuo Handa
syzbot is reporting hung task at p9_fd_close() [1], for p9_mux_poll_stop() from p9_conn_destroy() from p9_fd_close() is failing to interrupt already started kernel_read() from p9_fd_read() from p9_read_work() and/or kernel_write() from p9_fd_write() from p9_write_work() requests. Since p9_socket_open() sets O_NONBLOCK flag, p9_mux_poll_stop() does not need to interrupt kernel_read()/kernel_write(). However, since p9_fd_open() does not set O_NONBLOCK flag, but pipe blocks unless signal is pending, p9_mux_poll_stop() needs to interrupt kernel_read()/kernel_write() when the file descriptor refers to a pipe. In other words, pipe file descriptor needs to be handled as if socket file descriptor. We somehow need to interrupt kernel_read()/kernel_write() on pipes. A minimal change, which this patch is doing, is to set O_NONBLOCK flag from p9_fd_open(), for O_NONBLOCK flag does not affect reading/writing of regular files. But this approach changes O_NONBLOCK flag on userspace- supplied file descriptors (which might break userspace programs), and O_NONBLOCK flag could be changed by userspace. It would be possible to set O_NONBLOCK flag every time p9_fd_read()/p9_fd_write() is invoked, but still remains small race window for clearing O_NONBLOCK flag. If we don't want to manipulate O_NONBLOCK flag, we might be able to surround kernel_read()/kernel_write() with set_thread_flag(TIF_SIGPENDING) and recalc_sigpending(). Since p9_read_work()/p9_write_work() works are processed by kernel threads which process global system_wq workqueue, signals could not be delivered from remote threads when p9_mux_poll_stop() from p9_conn_destroy() from p9_fd_close() is called. Therefore, calling set_thread_flag(TIF_SIGPENDING)/recalc_sigpending() every time would be needed if we count on signals for making kernel_read()/kernel_write() non-blocking.

Summary: Performance: - outstanding FIEMAP speed improvement - algorithmic change how extents are enumerated leads to orders of magnitude speed boost (uncached and cached) - extent sharing check speedup (2.2x uncached, 3x cached) - add more cancellation points, allowing to interrupt seeking in files with large number of extents - more efficient hole and data seeking (4x uncached, 1.3x cached) - sample results: 256M, 32K extents: 4s -> 29ms (~150x) 512M, 64K extents: 30s -> 59ms (~550x) 1G, 128K extents: 225s -> 120ms (~1800x) - improved inode logging, especially for directories (on dbench workload throughput +25%, max latency -21%) - improved buffered IO, remove redundant extent state tracking, lowering memory consumption and avoiding rb tree traversal - add sysfs tunable to let qgroup temporarily skip exact accounting when deleting snapshot, leading to a speedup but requiring a rescan after that, will be used by snapper - support io_uring and buffered writes, until now it was just for direct IO, with the no-wait semantics implemented in the buffered write path it now works and leads to speed improvement in IOPS (2x), throughput (2.2x), latency (depends, 2x to 150x) - small performance improvements when dropping and searching for extent maps as well as when flushing delalloc in COW mode (throughput +5MB/s) User visible changes: - new incompatible feature block-group-tree adding a dedicated tree for tracking block groups, this allows a much faster load during mount and avoids seeking unlike when it's scattered in the extent tree items - this reduces mount time for many-terabyte sized filesystems - conversion tool will be provided so existing filesystem can also be updated in place - to reduce test matrix and feature combinations requires no-holes and free-space-tree (mkfs defaults since 5.15) - improved reporting of super block corruption detected by scrub - scrub also tries to repair super block and does not wait until next commit - discard stats and tunables are exported in sysfs (/sys/fs/btrfs/FSID/discard) - qgroup status is exported in sysfs (/sys/sys/fs/btrfs/FSID/qgroups/) - verify that super block was not modified when thawing filesystem Fixes: - FIEMAP fixes - fix extent sharing status, does not depend on the cached status where merged - flush delalloc so compressed extents are reported correctly - fix alignment of VMA for memory mapped files on THP - send: fix failures when processing inodes with no links (orphan files and directories) - fix race between quota enable and quota rescan ioctl - handle more corner cases for read-only compat feature verification - fix missed extent on fsync after dropping extent maps Core: - lockdep annotations to validate various transactions states and state transitions - preliminary support for fs-verity in send - more effective memory use in scrub for subpage where sector is smaller than page - block group caching progress logic has been removed, load is now synchronous - simplify end IO callbacks and bio handling, use chained bios instead of own tracking - add no-wait semantics to several functions (tree search, nocow, flushing, buffered write - cleanups and refactoring MM changes: - export balance_dirty_pages_ratelimited_flags" * tag 'for-6.1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (177 commits) btrfs: set generation before calling btrfs_clean_tree_block in btrfs_init_new_buffer btrfs: drop extent map range more efficiently btrfs: avoid pointless extent map tree search when flushing delalloc btrfs: remove unnecessary next extent map search btrfs: remove unnecessary NULL pointer checks when searching extent maps btrfs: assert tree is locked when clearing extent map from logging btrfs: remove unnecessary extent map initializations btrfs: remove the refcount warning/check at free_extent_map() btrfs: add helper to replace extent map range with a new extent map btrfs: move open coded extent map tree deletion out of inode eviction btrfs: use cond_resched_rwlock_write() during inode eviction btrfs: use extent_map_end() at btrfs_drop_extent_map_range() btrfs: move btrfs_drop_extent_cache() to extent_map.c btrfs: fix missed extent on fsync after dropping extent maps btrfs: remove stale prototype of btrfs_write_inode btrfs: enable nowait async buffered writes btrfs: assert nowait mode is not used for some btree search functions btrfs: make btrfs_buffered_write nowait compatible btrfs: plumb NOWAIT through the write path btrfs: make lock_and_cleanup_extent_if_need nowait compatible ...

2022-10-06perf mem/c2c: Add load store event mappings for AMDRavi Bangoria
The 'perf mem' and 'perf c2c' tools are wrappers around 'perf record' with mem load/ store events. IBS tagged load/store sample provides most of the information needed for these tools. Wire in the "ibs_op//" event as mem-ldst event for AMD. There are some limitations though: Only load/store micro-ops provide mem/c2c information. Whereas, IBS does not have a way to choose a particular type of micro-op to tag. This results in many non-LS micro-ops being tagged which appear as N/A in the perf report. IBS, being an uncore pmu from kernel point of view[1], does not support per process monitoring. Thus, perf mem/c2c on AMD are currently supported in per-cpu mode only. Example: $ sudo perf mem record -- -c 10000 ^C[ perf record: Woken up 227 times to write data ] [ perf record: Captured and wrote 58.760 MB perf.data (836978 samples) ] $ sudo perf mem report -F mem,sample,snoop Samples: 836K of event 'ibs_op//', Event count (approx.): 8418762 Memory access Samples Snoop N/A 700620 N/A L1 hit 126675 N/A L2 hit 424 N/A L3 hit 664 HitM L3 hit 10 N/A Local RAM hit 2 N/A Remote RAM (1 hop) hit 8558 N/A Remote Cache (1 hop) hit 3 N/A Remote Cache (1 hop) hit 2 HitM Remote Cache (2 hops) hit 10 HitM Remote Cache (2 hops) hit 6 N/A Uncached hit 4 N/A $ [1]: https://lore.kernel.org/lkml/20220829113347.295-1-ravi.bangoria@amd.com Signed-off-by: Ravi Bangoria <ravi.bangoria@amd.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ali Saidi <alisaidi@amazon.com> Cc: Ananth Narayan <ananth.narayan@amd.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Borislav Petkov <bp@alien8.de> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: H.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "This contains a series from Linus Walleij to unify the linux/io.h interface by making the ia64, alpha, parisc and sparc include asm-generic/io.h. All functions provided by the generic header are now available to all drivers, but the architectures can still override this. For the moment, mips and sh still don't include asm-generic/io.h but provide a full set of functions themselves. There are also a few minor cleanups unrelated to this" * tag 'asm-generic-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: alpha: add full ioread64/iowrite64 implementation parisc: Drop homebrewn io[read|write]64_[lo_hi|hi_lo] parisc: hide ioread64 declaration on 32-bit ia64: export memory_add_physaddr_to_nid to fix cxl build error asm-generic: Remove empty #ifdef SA_RESTORER parisc: Use the generic IO helpers parisc: Remove 64bit access on 32bit machines sparc: Fix the generic IO helpers alpha: Use generic <asm-generic/io.h>
