I think I see the issue. Will hopefully have a fix in a bit.

[PATCH] fork: return proper negative error code

[Christian Brauner]

Make sure to return a proper negative error code from copy_process()
when anon_inode_getfile() fails with CLONE_PIDFD.
Otherwise _do_fork() will not detect an error and get_task_pid() will
operator on a nonsensical pointer:

syzkaller has verified that this fixes the bug. The patch is sitting in
my fixes branch. I'm sending a PR for this in a little bit to get this
out of the way.

Thanks!

[GIT PULL] fixes for v5.2-rc8

[Christian Brauner]

Hi Linus,

This contains a single urgent fix for copy_process() in kernel/fork.c:

The following changes since commit 6fbc7275c7a9ba97877050335f290341a1fd8dbf:

  Linux 5.2-rc7 (2019-06-30 11:25:36 +0800)

are available in the Git repository at:

  git@gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux tags/for-linus-20190701

for you to fetch changes up to 28dd29c06d0dede4b32b2c559cff21955a830928:

  fork: return proper negative error code (2019-07-01 16:43:30 +0200)

With Al's removal of ksys_close() from cleanup paths in copy_process() a
bug was introduced. When anon_inode_getfile() failed the cleanup was
correctly performed but the error code was not propagated to callers of
copy_process() causing them to operate on a nonsensical pointer. The fix is
a simple on-liner which makes sure that a proper negative error code is
returned from copy_process().
syzkaller has also verified that the bug is not reproducible with the patch
in this branch.

Please consider pulling these changes from the signed for-linus-20190701 tag.

Thanks!
Christian
