*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net/mlx5e: xsk: Fix crash on regular rq reactivation<br />
<br />
When the regular rq is reactivated after the XSK socket is closed<br />
it could be reading stale cqes which eventually corrupts the rq.<br />
This leads to no more traffic being received on the regular rq and a<br />
crash on the next close or deactivation of the rq.<br />
<br />
Kal Cuttler Conely reported this issue as a crash on the release<br />
path when the xdpsock sample program is stopped (killed) and restarted<br />
in sequence while traffic is running.<br />
<br />
This patch flushes all cqes when during the rq flush. The cqe flushing<br />
is done in the reset state of the rq. mlx5e_rq_to_ready code is moved<br />
into the flush function to allow for this.
