It will return immediately if there's any data in the ring buffer whereas a read will block until the watermark (defined by the tracefs buffer_percent file) is hit. That is, a select() or poll() will return as if there's data available, but then the following read will block. This is broken for the way select()s and poll()s are supposed to work.

FAILED: patch "[PATCH] tracing/ring-buffer: Have polling block on watermark" failed to apply to 4.19-stable tree

It will return immediately if there's any data in the ring buffer whereas a read will block until the watermark (defined by the tracefs buffer_percent file) is hit. That is, a select() or poll() will return as if there's data available, but then the following read will block. This is broken for the way select()s and poll()s are supposed to work. Have the polling on the ring buffer also block the same way reads and splice does on the ring buffer.

Re: KASAN: use-after-free Read in tc_chain_fill_node

by syzbot

This bug is marked as fixed by commit: net: core: netlink: add helper refcount dec and lock function net: sched: add helper function to take reference to Qdisc net: sched: extend Qdisc with rcu net: sched: rename qdisc_destroy() to qdisc_put() net: sched: use Qdisc rcu API instead of relying on rtnl lock But I can't find it in any tested tree for more than 90 days. Is it a correct commit? Please update it by replying: #syz fix: exact-commit-title Until then the bug is still considered open and new crashes with the same signature are ignored.

[PATCH v3] nilfs2: Fix nilfs_sufile_mark_dirty() not set segment usage as dirty

by Chen Zhongjin

When extending segments, nilfs_sufile_alloc() is called to get an unassigned segment, then mark it as dirty to avoid accidentally allocating the same segment in the future. But for some special cases such as a corrupted image it can be unreliable. If such corruption of the dirty state of the segment occurs, nilfs2 may reallocate a segment that is in use and pick the same segment for writing twice at the same time. This will cause the problem reported by syzkaller: https://syzkaller.appspot.com/bug?id=c7c4748e11ffcc367cef04f76e02e931833cbd… This case started with segbuf1.segnum = 3, nextnum = 4 when constructed. It supposed segment 4 has already been allocated and marked as dirty. However the dirty state was corrupted and segment 4 usage was not dirty. For the first time nilfs_segctor_extend_segments() segment 4 was allocated again, which made segbuf2 and next segbuf3 had same segment 4. sb_getblk() will get same bh for segbuf2 and segbuf3, and this bh is added to both buffer lists of two segbuf. It makes the lists broken which causes NULL pointer dereference. Fix the problem by setting usage as dirty every time in nilfs_sufile_mark_dirty(), which is called during constructing current segment to be written out and before allocating next segment.
