Revision 0aec12d97b2036af0946e3d582144739860ac07b authored by Yevgeny Kliteynik on 11 January 2022, 01:00:03 UTC, committed by Saeed Mahameed on 24 February 2022, 00:08:10 UTC
When adding a rule with 32 destinations, we hit the following out-of-band
access issue:
BUG: KASAN: slab-out-of-bounds in mlx5_cmd_dr_create_fte+0x18ee/0x1e70
This patch fixes the issue by both increasing the allocated buffers to
accommodate for the needed actions and by checking the number of actions
to prevent this issue when a rule with too many actions is provided.
Fixes: 1ffd498901c1 ("net/mlx5: DR, Increase supported num of actions to 32")
