Public bug reported: SRU Justification:
[Impact] This stable patchset update affects only the FUSE filesystem, since we have received bug reports about FUSE causing problems with the Bionic kernel, see also bug #1823972. The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from a mainline/stable Linux tree or a minimally backported form of that patch. The following upstream stable patches should be included in the Ubuntu kernel: upstream stable patchset 2019-04-12 (ported from v4.15 .. v5.0) from git://git.kernel.org/ fuse: decrement NR_WRITEBACK_TEMP on the right page fuse: call pipe_buf_release() under pipe lock fuse: handle zero sized retrieve correctly fuse: continue to send FUSE_RELEASEDIR when FUSE_OPEN returns ENOSYS fuse: fix use-after-free in fuse_direct_IO() fuse: fix possibly missed wake-up after abort fuse: fix leaked notify reply fuse: fix blocked_waitq wakeup fuse: set FR_SENT while locked fuse: Fix use-after-free in fuse_dev_do_write() fuse: Fix use-after-free in fuse_dev_do_read() fuse: Don't access pipe->buffers without pipe_lock() fuse: Fix oops at process_init_reply() fuse: umount should wait for all requests fuse: fix unlocked access to processing queue fuse: fix double request_end() ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Andrea Righi (arighi) Status: Invalid ** Affects: linux (Ubuntu Bionic) Importance: Medium Status: In Progress ** Tags: kernel-stable-tracking-bug ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Andrea Righi (arighi) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824553 Title: Bionic update: update stable patchset for fuse 2019-04-12 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824553/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
