Re: [PATCH openEuler-1.0-LTS 1/1] ras: report cpu logical index to userspace in arm event
by Xie XiuQi 25 Nov '21

Hi，这个补丁在 openEuler 20.03 有合入吗？修改 trace 格式相当于是修改ABI了，为避免与上层应用，如rasdaemon 等存在兼容性问题，这个在之前版本也是修改过吗？还有，这个如果是为了增加 cpu logical index，是不是看一看推一下上游社区，免得每个版本都 port 这个补丁。 On 2021/11/25 15:30, lostway(a)zju.edu.cn wrote: > From: Lostwayzxc <luoshengwei(a)huawei.com> > > kunpeng inclusion > category: feature > bugzilla: https://gitee.com/openeuler/kernel/issues/I4IG00?from=project-issue > CVE: NA > > When the arm event is reported, the rasdaemon needs to know the cpu logical index, > but there is only mpidr without mapping between it and cpu logical index.

[PATCH OLK-5.10] atlantic: Fix OOB read and write in hw_atl_utils_fw_rpc_wait

From: Zekun Shen <bruceshenzk(a)gmail.com> mainline inclusion from mainline commit b922f622592af76b57cbc566eaeccda0b31a3496 bugzilla: 185788 https://e.gitee.com/open_euler/dashboard?issue=I4IYTG CVE: CVE-2021-43975 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This bug report shows up when running our research tools. The reports is SOOB read, but it seems SOOB write is also possible a few lines below. In details, fw.len and sw.len are inputs coming from io. A len over the size of self->rpc triggers SOOB. The patch fixes the bugs by adding sanity checks. The bugs are triggerable with compromised/malfunctioning devices. They are potentially exploitable given they first leak up to 0xffff bytes and able to overwrite the region later. The patch is tested with QEMU emulater. This is NOT tested with a real device. Attached is the log we found by fuzzing.

[PATCH openEuler-1.0-LTS] drm/ioctl: Ditch DRM_UNLOCKED except for the legacy vblank ioctl
by Yang Yingliang 23 Nov '21

23 Nov '21

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> mainline inclusion from mainline-v5.4-rc1 commit 75426367cd377120a256cad0b35b02eec4b83591 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4JI7R CVE: NA -------------------------------- This completes Emil's series of removing DRM_UNLOCKED from modern drivers. It's entirely cargo-culted since we ignore it on non-DRIVER_LEGACY drivers since: commit ea487835e8876abf7ad909636e308c801a2bcda6 Author: Daniel Vetter <daniel.vetter(a)ffwll.ch> Date: Mon Sep 28 21:42:40 2015 +0200 drm: Enforce unlocked ioctl operation for kms driver ioctls Now justifying why we can do this for legacy drives too (and hence close the source of all the bogus copypasting) is a bit more involved. DRM_UNLOCKED was introduced in: commit ed8b67040965e4fe695db333d5914e18ea5f146f Author: Arnd Bergmann <arnd(a)arndb.de> Date: Wed Dec 16 22:17:09 2009 +0000 drm: convert drm_ioctl to unlocked_ioctl As a immediate hack to keep i810 happy, which would have deadlocked without this trickery. The old BKL is automatically dropped in schedule(), and hence the i810 vs. mmap_sem deadlock didn't actually cause a real deadlock. But with a mutex it would. The solution was to annotate these as DRM_UNLOCKED and mark i810 unsafe on SMP machines. This conversion caused a regression, because unlike the BKL a mutex isn't dropped over schedule (that thing again), which caused a vblank wait in one thread to block the entire desktop and all its apps. Back then we did vblank scheduling by blocking in the client, awesome isn't it. This was fixed quickly in (ok not so quickly, took 2 years): commit 8f4ff2b06afcd6f151868474a432c603057eaf56 Author: Ilija Hadzic <ihadzic(a)research.bell-labs.com> Date: Mon Oct 31 17:46:18 2011 -0400 drm: do not sleep on vblank while holding a mutex All the other DRM_UNLOCKED annotations for all the core ioctls was work to reach finer-grained locking for modern drivers. This took years, and culminated in: commit fdd5b877e9ebc2029e1373b4a3cd057329a9ab7a Author: Daniel Vetter <daniel.vetter(a)ffwll.ch> Date: Sat Dec 10 22:52:54 2016 +0100 drm: Enforce BKL-less ioctls for modern drivers DRM_UNLOCKED was never required by any legacy drivers, except for the vblank_wait IOCTL. Therefore we will not regress these old drivers by going back to where we've been in 2011. For all modern drivers nothing will change. To make this perfectly clear, also add a comment to DRM_UNLOCKED. v2: Don't forget about drm_ioc32.c (Michel).
