[PATCH 1/2] net: stmmac: do not clear TBS enable bit on link up/down

by Esben Haabendal

With the dma conf being reallocated on each call to stmmac_open(), any information in there is lost, unless we specifically handle it. The STMMAC_TBS_EN bit is set when adding an etf qdisc, and the etf qdisc therefore would stop working when link was set down and then back up.

Consequently, the fix is missing on the popular Ubuntu versions like 20.04 (KNL v5.15.x) and 22.04.3 (KNL v6.2.x). For that reason, people still experience infinite loops when building Linux on those systems. To overcome the issue, people fall back to workarounds [3-4]. The patch seems to apply cleanly to v6.2, but not to v5.15 (v5.15 backport attempt failed miserably). Is there a chance for: - Stable maintainers to accept the clean backport to v6.2? - BTRFS experts to suggest a conflict resolution for v5.15?

[PATCH 5.15] btrfs: fix infinite directory reads

by Qu Wenruo

From: Filipe Manana <fdmanana(a)suse.com> [ Upstream commit b4c639f699349880b7918b861e1bd360442ec450 ] The readdir implementation currently processes always up to the last index it finds. This however can result in an infinite loop if the directory has a large number of entries such that they won't all fit in the given buffer passed to the readdir callback, that is, dir_emit() returns a non-zero value. Because in that case readdir() will be called again and if in the meanwhile new directory entries were added and we still can't put all the remaining entries in the buffer, we keep repeating this over and over. The following C program and test script reproduce the problem: $ cat /mnt/readdir_prog.c #include <sys/types.h> #include <dirent.h> #include <stdio.h> int main(int argc, char *argv[]) { DIR *dir = opendir("."); struct dirent *dd; while ((dd = readdir(dir))) { printf("%s\n", dd->d_name); rename(dd->d_name, "TEMPFILE"); rename("TEMPFILE", dd->d_name); } closedir(dir); } $ gcc -o /mnt/readdir_prog /mnt/readdir_prog.c $ cat test.sh #!/bin/bash DEV=/dev/sdi MNT=/mnt/sdi mkfs.btrfs -f $DEV &> /dev/null #mkfs.xfs -f $DEV &> /dev/null #mkfs.ext4 -F $DEV &> /dev/null mount $DEV $MNT mkdir $MNT/testdir for ((i = 1; i <= 2000; i++)); do echo -n > $MNT/testdir/file_$i done cd $MNT/testdir /mnt/readdir_prog cd /mnt umount $MNT This behaviour is surprising to applications and it's unlike ext4, xfs, tmpfs, vfat and other filesystems, which always finish. In this case where new entries were added due to renames, some file names may be reported more than once, but this varies according to each filesystem - for example ext4 never reported the same file more than once while xfs reports the first 13 file names twice. So change our readdir implementation to track the last index number when opendir() is called and then make readdir() never process beyond that index number. This gives the same behaviour as ext4.

[PATCH] wifi: cfg80211: fix wiphy delayed work queueing

by Johannes Berg

From: Johannes Berg <johannes.berg(a)intel.com> When a wiphy work is queued with timer, and then again without a delay, it's started immediately but *also* started again after the timer expires. This can lead, for example, to warnings in mac80211's offchannel code as reported by Jouni. Running the same work twice isn't expected, of course. Fix this by deleting the timer at this point, when queuing immediately due to delay=0.

[tip: timers/urgent] clocksource: Skip watchdog check for large watchdog intervals

by tip-bot2 for Jiri Wiesner

The following commit has been merged into the timers/urgent branch of tip: Commit-ID: 644649553508b9bacf0fc7a5bdc4f9e0165576a5 Gitweb: https://git.kernel.org/tip/644649553508b9bacf0fc7a5bdc4f9e0165576a5 Author: Jiri Wiesner <jwiesner(a)suse.de> AuthorDate: Mon, 22 Jan 2024 18:23:50 +01:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Thu, 25 Jan 2024 09:13:16 +01:00 clocksource: Skip watchdog check for large watchdog intervals There have been reports of the watchdog marking clocksources unstable on machines with 8 NUMA nodes: clocksource: timekeeping watchdog on CPU373: Marking clocksource 'tsc' as unstable because the skew is too large: clocksource: 'hpet' wd_nsec: 14523447520 clocksource: 'tsc' cs_nsec: 14524115132 The measured clocksource skew - the absolute difference between cs_nsec and wd_nsec - was 668 microseconds: cs_nsec - wd_nsec = 14524115132 - 14523447520 = 667612 The kernel used 200 microseconds for the uncertainty_margin of both the clocksource and watchdog, resulting in a threshold of 400 microseconds (the md variable). Both the cs_nsec and the wd_nsec value indicate that the readout interval was circa 14.5 seconds. The observed behaviour is that watchdog checks failed for large readout intervals on 8 NUMA node machines. This indicates that the size of the skew was directly proportinal to the length of the readout interval on those machines. The measured clocksource skew, 668 microseconds, was evaluated against a threshold (the md variable) that is suited for readout intervals of roughly WATCHDOG_INTERVAL, i.e. HZ >> 1, which is 0.5 second. The intention of 2e27e793e280 ("clocksource: Reduce clocksource-skew threshold") was to tighten the threshold for evaluating skew and set the lower bound for the uncertainty_margin of clocksources to twice WATCHDOG_MAX_SKEW. Later in c37e85c135ce ("clocksource: Loosen clocksource watchdog constraints"), the WATCHDOG_MAX_SKEW constant was increased to 125 microseconds to fit the limit of NTP, which is able to use a clocksource that suffers from up to 500 microseconds of skew per second. Both the TSC and the HPET use default uncertainty_margin. When the readout interval gets stretched the default uncertainty_margin is no longer a suitable lower bound for evaluating skew - it imposes a limit that is far stricter than the skew with which NTP can deal. The root causes of the skew being directly proportinal to the length of the readout interval are: * the inaccuracy of the shift/mult pairs of clocksources and the watchdog * the conversion to nanoseconds is imprecise for large readout intervals Prevent this by skipping the current watchdog check if the readout interval exceeds 2 * WATCHDOG_INTERVAL. Considering the maximum readout interval of 2 * WATCHDOG_INTERVAL, the current default uncertainty margin (of the TSC and HPET) corresponds to a limit on clocksource skew of 250 ppm (microseconds of skew per second). To keep the limit imposed by NTP (500 microseconds of skew per second) for all possible readout intervals, the margins would have to be scaled so that the threshold value is proportional to the length of the actual readout interval. As for why the readout interval may get stretched: Since the watchdog is executed in softirq context the expiration of the watchdog timer can get severely delayed on account of a ksoftirqd thread not getting to run in a timely manner. Surely, a system with such belated softirq execution is not working well and the scheduling issue should be looked into but the clocksource watchdog should be able to deal with it accordingly.

Since this function is called with the port lock held, this can be a problem in case that setting the GPIO line can sleep (e.g. if a GPIO expander is used which is connected via SPI or I2C). Avoid this issue by moving the GPIO setting outside of the port lock into the serial core and thus making it a generic feature. Also with commit c54d48543689 ("serial: stm32: Add support for rs485 RX_DURING_TX output GPIO") the SER_RS485_RX_DURING_TX flag is only set if a rx-during-tx GPIO is _not_ available, which is wrong. Fix this, too. Furthermore reset old GPIO settings in case that changing the RS485 configuration failed.

[PATCH v2 01/15] ubifs: Set page uptodate in the correct place

by Matthew Wilcox (Oracle)

Page cache reads are lockless, so setting the freshly allocated page uptodate before we've overwritten it with the data it's supposed to have in it will allow a simultaneous reader to see old data. Move the call to SetPageUptodate into ubifs_write_end(), which is after we copied the new data into the page.
