BugLink: https://bugs.launchpad.net/bugs/1848589 [ Upstream commit a07db5c0 ] On !CONFIG_RT_GROUP_SCHED configurations it is currently not possible to move RT tasks between cgroups to which CPU controller has been attached; but it is oddly possible to first move tasks around and then make them RT (setschedule to FIFO/RR). E.g.: # mkdir /sys/fs/cgroup/cpu,cpuacct/group1 # chrt -fp 10 $$ # echo $$ > /sys/fs/cgroup/cpu,cpuacct/group1/tasks bash: echo: write error: Invalid argument # chrt -op 0 $$ # echo $$ > /sys/fs/cgroup/cpu,cpuacct/group1/tasks # chrt -fp 10 $$ # cat /sys/fs/cgroup/cpu,cpuacct/group1/tasks 2345 2598 # chrt -p 2345 pid 2345's current scheduling policy: SCHED_FIFO pid 2345's current scheduling priority: 10 Also, as Michal noted, it is currently not possible to enable CPU controller on unified hierarchy with !CONFIG_RT_GROUP_SCHED (if there are any kernel RT threads in root cgroup, they can't be migrated to the newly created CPU controller's root in cgroup_update_dfl_csses()). Existing code comes with a comment saying the "we don't support RT-tasks being in separate groups". Such comment is however stale and belongs to pre-RT_GROUP_SCHED times. Also, it doesn't make much sense for !RT_GROUP_ SCHED configurations, since checks related to RT bandwidth are not performed at all in these cases. Make moving RT tasks between CPU controller groups viable by removing special case check for RT (and DEADLINE) tasks. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1848589 [ Upstream commit f6cad8df ] The load_balance() has a dedicated mecanism to detect when an imbalance is due to CPU affinity and must be handled at parent level. In this case, the imbalance field of the parent's sched_group is set. The description of sg_imbalanced() gives a typical example of two groups of 4 CPUs each and 4 tasks each with a cpumask covering 1 CPU of the first group and 3 CPUs of the second group. Something like: { 0 1 2 3 } { 4 5 6 7 } * * * * But the load_balance fails to fix this UC on my octo cores system made of 2 clusters of quad cores. Whereas the load_balance is able to detect that the imbalanced is due to CPU affinity, it fails to fix it because the imbalance field is cleared before letting parent level a chance to run. In fact, when the imbalance is detected, the load_balance reruns without the CPU with pinned tasks. But there is no other running tasks in the situation described above and everything looks balanced this time so the imbalance field is immediately cleared. The imbalance field should not be cleared if there is no other task to move when the imbalance is detected. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1848589 [ Upstream commit 765bb861 ] When CONFIG_DVB_DIB9000 is disabled, we can still compile code that now fails to link against dibx000_i2c_set_speed: drivers/media/usb/dvb-usb/dib0700_devices.o: In function `dib01x0_pmu_update.constprop.7': dib0700_devices.c:(.text.unlikely+0x1c9c): undefined reference to `dibx000_i2c_set_speed' The call sites are both through dib01x0_pmu_update(), which gets passed an 'i2c' pointer from dib9000_get_i2c_master(), which has returned NULL. Checking this pointer seems to be a good idea anyway, and it avoids the link failure in most cases. Sean Young found another case that is not fixed by that, where certain gcc versions leave an unused function in place that causes the link error, but adding an explict IS_ENABLED() check also solves this.

BugLink: https://bugs.launchpad.net/bugs/1848589 [ Upstream commit a37d0862 ] As Pavel Machek reported: "We normally use -EUCLEAN to signal filesystem corruption. Plus, it is good idea to report it to the syslog and mark filesystem as "needing fsck" if filesystem can do that." Still we need improve the original patch with: - use unlikely keyword - add message print - return EUCLEAN However, after rethink this patch, I don't think we should add such condition check here as below reasons: - We have already checked the field in f2fs_sanity_check_ckpt(), - If there is fs corrupt or security vulnerability, there is nothing to guarantee the field is integrated after the check, unless we do the check before each of its use, however no filesystem does that. - We only have similar check for bitmap, which was added due to there is bitmap corruption happened on f2fs' runtime in product. - There are so many key fields in SB/CP/NAT did have such check after f2fs_sanity_check_{sb,cp,..}. So I propose to revert this unneeded check. This reverts commit 56f3ce67. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1848589 [ Upstream commit c9c96e30 ] When allocating a range of LPIs for a Multi-MSI capable device, this allocation extended to the closest power of 2. But on the release path, the interrupts are released one by one. This results in not releasing the "extra" range, leaking the its_device. Trying to reprobe the device will then fail. Fix it by releasing the LPIs the same way we allocate them. Fixes: 8208d170 ("irqchip/gic-v3-its: Align PCI Multi-MSI allocation on their size") Reported-by:

BugLink: https://bugs.launchpad.net/bugs/1848589 [ Upstream commit 79c92ca4 ] When receiving a deauthentication/disassociation frame from a TDLS peer, a station should not disconnect the current AP, but only disable the current TDLS link if it's enabled. Without this change, a TDLS issue can be reproduced by following the steps as below: 1. STA-1 and STA-2 are connected to AP, bidirection traffic is running between STA-1 and STA-2. 2. Set up TDLS link between STA-1 and STA-2, stay for a while, then teardown TDLS link. 3. Repeat step #2 and monitor the connection between STA and AP. During the test, one STA may send a deauthentication/disassociation frame to another, after TDLS teardown, with reason code 6/7, which means: Class 2/3 frame received from nonassociated STA. On receive this frame, the receiver STA will disconnect the current AP and then reconnect. It's not a expected behavior, purpose of this frame should be disabling the TDLS link, not the link with AP.

Currently to check the state chip_ready() is used correctly as described by the flash memory S29GL256P11TFI01 datasheet. Also chip_good() is used to check if the write is succeeded and it was implemented by the commit fb4a90bf ("[MTD] CFI-0002 - Improve error checking"). But actually the write failure is caused on some platforms and also it can be fixed by using chip_good() to check the state and retry instead. Also it seems that it is caused after repeated about 1,000 times to retry the write one word with the reset command. By using chip_good() to check the state to be done it can be reduced the retry with reset. It is depended on the actual flash chip behavior so the root cause is unknown.

BugLink: https://bugs.launchpad.net/bugs/1848589 commit 416dacb8 upstream. The syzbot fuzzer has reported a pair of problems in the hidraw_ioctl() function: slab-out-of-bounds read and use-after-free read.
