[PATCH 5.15.y v2 0/2] Return EADDRNOTAVAIL when func matches several symbols during kprobe creation

by Francis Laniel

Hi! The second patch of this series caused some troubles on 5.15.y, I apologize about it [1]. As a consequence, I was asked to build and test all the stable kernels with this patch for several architectures [2]. I would nonetheless like to emphasize this is the first time I sent a patch to the stable kernel and the problem is the result of lack of experience (Do I need to change the config? Do I need to change the patch? Do I need to find another patch solving the CONFIG_LIVEPATCH dependencies? were the type of questions I had in mind before sending it) rather than a desire to harm. Regarding the series, the first patch is only needed on kernel 5.15. Indeed the dependencies on CONFIG_LIVEPATCH for kallsyms_on_each_symbol() was added in 3e3552056ab4 ("kallsyms: only build {,module_}kallsyms_on_each_symbol when required"). This commit was first added to kernel 5.12, as git indicates it: $ git name-rev --tags --name-only 3e3552056ab4 v5.12-rc1~67^2~8 Moreover, the first patch of this series, i.e. d721def7392a ("kallsyms: Make kallsyms_on_each_symbol generally available") was first added in: $ git name-rev --tags --name-only d721def7392a v5.19-rc1~159^2~4^2~38^2~4 So, my patch only needs the first patch for the 5.15 kernel. Using this patch as a solution for mine was pointed by Guenter Roeck [3]. So, I decided to build and test the stable kernels with this patch for several architectures. Regarding building, I did so using the following script: ------------------------------------------ for release in 4.14 4.19 5.4 5.10 5.15; do git checkout "linux-${release}.y" for arch in $(tuxmake build -A -r docker); do outdir="$(git rev-parse --abbrev-ref HEAD)/${arch}" mkdir -p $outdir tuxmake -q -r docker -a $arch --kconfig-add kvm_guest.config --kconfig-add CONFIG_KPROBES=y -o $outdir done done ------------------------------------------ Note that, the branches were prepared before running the script with the patch applied. I obtained the following, i.e. there were no build errors: ------------------------------------------ ../stable: linux-4.14.y linux-4.19.y linux-5.10.y linux-5.15.y linux-5.4.y ../stable/linux-4.14.y:

directories, like hexagon, are empty. This is perfectly normal as there is no gcc toolchain for these architectures. Regarding testing, I only tested for arm and x86_64 for several reasons: 1. My script supports a few architectures (e.g. sparc is not supported) [4]. 2. Some of the supported architecture does not handle correctly ssh (I still need to polish this). 3. For arm64, I did not have the /sys/kernel/tracing available despite having CONFIG_KPROBES. I may have forgotten a CONFIG_ for this kernel, thus I did not test it. The following script was used to test: ------------------------------------------ declare -A kernel_arches=( ['armel']='arm' ['amd64']='x86_64') declare -A kernel_images=( ['armel']='zImage' ['amd64']='bzImage') for release in 4.14 4.19 5.4 5.10 5.15; do for qemu_arch in "${!kernel_arches[@]}"; do kernel_arch=${kernel_arches[${qemu_arch}]} kernel_image=${kernel_images[${qemu_arch}]} bash run_extern_kernel.sh $qemu_arch ../stable/linux-${release}.y/$kernel_arch/$kernel_image sleep 30 ssh -p 10022 root@localhost uname -mr ssh -p 10022 root@localhost bash -c "echo 'p:myprobe name_show' > /sys/kernel/tracing/kprobe_events" ssh -p 10022 root@localhost poweroff sleep 30 done done ------------------------------------------ And it gave the corresponding output, which proves everything works as expected: ------------------------------------------ 4.14.331-00002-g7aa12df051fa armv7l bash: line 1: echo: write error: Cannot assign requested address 4.14.331+ x86_64 bash: line 1: echo: write error: Cannot assign requested address 4.19.300-00001-g7cac16479cd7 armv7l bash: line 1: echo: write error: Cannot assign requested address 4.19.300+ x86_64 bash: line 1: echo: write error: Cannot assign requested address 5.4.262-00001-g74ca00e4af8f armv7l bash: line 1: echo: write error: Cannot assign requested address 5.4.262+ x86_64 bash: line 1: echo: write error: Cannot assign requested address 5.10.202-00001-gfff8e5c3be26 armv7l bash: line 1: echo: write error: Cannot assign requested address 5.10.202+ x86_64 bash: line 1: echo: write error: Cannot assign requested address 5.15.141-00002-gfe40e56ab1f0 armv7l bash: line 1: echo: write error: Cannot assign requested address 5.15.141+ x86_64 bash: line 1: echo: write error: Cannot assign requested address ------------------------------------------ I hope the proof given here would lead this patch to be merged in the stable kernel. If this is not enough, I will do my best to provide more.

[PATCH 5.15.y 000/154] ksmbd backport patches for 5.15.y

by Namjae Jeon

This patchset backport ksmbd patches between 5.16 and 6.7-rc5 kernel. Bug fixes and CVE patches were not applied well due to clean-up and new feautre patches. To facilitate backport, This patch-set included clean-up patches and new feature patches of ksmbd for stable 5.15 kernel. -- 2.25.1

[PATCH] drm/mgag200: Fix gamma lut not initialized for G200ER, G200EV, G200SE

by Jocelyn Falempe

When mgag200 switched from simple KMS to regular atomic helpers, the initialization of the gamma settings was lost. This leads to a black screen, if the bios/uefi doesn't use the same pixel color depth. This has been fixed with commit ad81e23426a6 ("drm/mgag200: Fix gamma lut not initialized.") for most G200, but G200ER, G200EV, G200SE use their own version of crtc_helper_atomic_enable() and need to be fixed too.

[PATCH 1/2] drm: Don't unref the same fb many times by mistake due to deadlock handling

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl() we proceed to unref the fb and then retry the whole thing from the top. But we forget to reset the fb pointer back to NULL, and so if we then get another error during the retry, before the fb lookup, we proceed the unref the same fb again without having gotten another reference. The end result is that the fb will (eventually) end up being freed while it's still in use. Reset fb to NULL once we've unreffed it to avoid doing it again until we've done another fb lookup. This turned out to be pretty easy to hit on a DG2 when doing async flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I saw that drm_closefb() simply got stuck in a busy loop while walking the framebuffer list. Fortunately I was able to convince it to oops instead, and from there it was easier to track down the culprit.

[PATCH 3/4] ext4: avoid bb_free and bb_fragments inconsistency in mb_free_blocks()

by Baokun Li

After updating bb_free in mb_free_blocks, it is possible to return without updating bb_fragments because the block being freed is found to have already been freed, which leads to inconsistency between bb_free and bb_fragments. Since the group may be unlocked in ext4_grp_locked_error(), this can lead to problems such as dividing by zero when calculating the average fragment length. Therefore, to ensure consistency, move the update of bb_free to after the block double-free check.
