[PATCH 0/2] spi: fsl-qspi: Fix kernel panic when unbinding the SPI host

x86 kexec problem in stable 6.1.129 and later due to change related to PGD allocation

by Elias Rudberg

Hello, The following change seems to cause kexec to sometimes fail (not every time but about 50% chance) for the stable 6.1 kernels, 6.1.129 and later: 6821918f4519 ("x86/kexec: Allocate PGD for x86_64 transition page tables separately") The commit message for that commit states that it is dependent on another change "x86/mm: Add _PAGE_NOPTISHADOW bit to avoid updating userspace page tables" but that change does not seem to have been done in the 6.1 kernel series, which could explain why the 6821918f4519 change causes problems for 6.1. This appears to be a problem only for 6.1, for the 6.6 and later stable kernels there is no problem. I think the reason this problem is seen only for 6.1 and not for 6.6 and later is that the change "x86/kexec: Allocate PGD for x86_64 transition page tables separately" relies on things that are not available in 6.1. In the tests I have done, kexec is called via u-root. More details are available here: https://git.glasklar.is/system-transparency/core/stboot/-/issues/227 Cheers, Elias

[PATCH 5.10] btrfs: have proper error handling in btrfs_init_reloc_root

From: Josef Bacik <josef(a)toxicpanda.com> commit 00bb36a0e76ab7e94bdd70d561baf25f9bc1415d upstream. create_reloc_root will return errors in the future, and __add_reloc_root can return ENOMEM or EEXIST, so handle these errors properly.

BUG in LTS 5.15.x cpusets with tasks launched by newer systemd

by James Thomas

Hello all, I encountered an issue with the CPU affinity of tasks launched by systemd in a slice, after updating from systemd 254 to by systemd >= 256, on the LTS 5.15.x branch (tested on v5.15.179). Despite the slice file stipulating AllowedCPUS=2 (and confirming this was set in /sys/fs/cgroup/test.slice/cpuset.cpus) tasks launched in the slice would have the CPU affinity of the system.slice (i.e all by default) rather than 2. To reproduce: * Check kernel version and systemd version (I used a debian testing image for testing) ``` # uname -r 5.15.179 # systemctl --version systemd 257 (257.4-3) ... ``` * Create a test.slice with AllowedCPUS=2 ``` # cat <<EOF > /usr/lib/systemd/system/test.slice [Unit] Description=Test slice Before=slices.target [Slice] AllowedCPUs=2 [Install] WantedBy=slices.target EOF # systemctl daemon-reload && systemctl start test.slice ``` * Confirm cpuset ``` # cat /sys/fs/cgroup/test.slice/cpuset.cpus 2 ``` * Launch task in slice ``` # systemd-run --slice test.slice yes Running as unit: run-r9187b97c6958498aad5bba213289ac56.service; invocation ID: f470f74047ac43b7a60861d03a7ef6f9 # cat /sys/fs/cgroup/test.slice/run-r9187b97c6958498aad5bba213289ac56.service/cgroup.procs 317 ``` # Check affinity ``` # taskset -pc 317 pid 317's current affinity list: 0-7 ``` This issue is fixed by applying upstream commits: 18f9a4d47527772515ad6cbdac796422566e6440 cgroup/cpuset: Skip spread flags update on v2 and 42a11bf5c5436e91b040aeb04063be1710bb9f9c cgroup/cpuset: Make cpuset_fork() handle CLONE_INTO_CGROUP properly With these applied: ``` # systemd-run --slice test.slice yes Running as unit: run-r442c444559ff49f48c6c2b8325b3b500.service; invocation ID: 5211167267154e9292cb6b854585cb91 # cat /sys/fs/cgroup/test.slice/run-r442c444559ff49f48c6c2b8325b3b500.service/cgroup.procs 291 # taskset -pc 291 pid 291's current affinity list: 2 ``` Perhaps these are a good candidate for backport onto the 5.15 LTS branch?

[PATCH v2] exfat: fix random stack corruption after get_block

by Sungjong Seo

When get_block is called with a buffer_head allocated on the stack, such as do_mpage_readpage, stack corruption due to buffer_head UAF may occur in the following race condition situation. <CPU 0> <CPU 1> mpage_read_folio <<bh on stack>> do_mpage_readpage exfat_get_block bh_read __bh_read get_bh(bh) submit_bh wait_on_buffer ... end_buffer_read_sync __end_buffer_read_notouch unlock_buffer <<keep going>> ... ... ... ... <<bh is not valid out of mpage_read_folio>> . . another_function <<variable A on stack>> put_bh(bh) atomic_dec(bh->b_count) * stack corruption here * This patch returns -EAGAIN if a folio does not have buffers when bh_read needs to be called. By doing this, the caller can fallback to functions like block_read_full_folio(), create a buffer_head in the folio, and then call get_block again. Let's do not call bh_read() with on-stack buffer_head.
