Date: Tue, 22 Dec 2020 16:43:25 -0800 From: Casey Schaufler <casey@...aufler-ca.com> To: Linus Torvalds <torvalds@...ux-foundation.org> Cc: LKML <linux-kernel@...r.kernel.org>, Linux Security Module list <linux-security-module@...r.kernel.org>, Casey Schaufler <casey@...aufler-ca.com> Subject: [GIT PULL] Smack additional patch for v5.11 Hello Linus Sorry for the 2nd pull request, but this is a fairly important fix for the privilege handling of smackfs in the face of io_uring. The novel use of kernel threads in io_uring invalidated an long standing assumption regarding the privilege of kernel threads. The fix is simple and safe. It was provided by Jens Axboe <axboe@...nel.dk> and has been tested. -- The following changes since commit 9b0072e2b2b588ad75c94f2c6e6c52c8f4bd2657: security/smack: remove unused varible 'rc' (2020-11-16 17:26:31 -0800) are available in the Git repository at: https://github.com/cschaufler/smack-next smack-for-5.11 for you to fetch changes up to 942cb357ae7d9249088e3687ee6a00ed2745a0c7: Smack: Handle io_uring kernel thread privileges (2020-12-22 15:34:24 -0800) ---------------------------------------------------------------- Casey Schaufler (1): Smack: Handle io_uring kernel thread privileges security/smack/smack_access.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
