[PATCH][next] net/mlx5: fix kvfree of uninitialized pointer spec

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently when a call to  esw_vport_create_legacy_ingress_acl_group
fails the error exit path to label 'out' will cause a kvfree on the
uninitialized pointer spec.  Fix this by ensuring pointer spec is
initialized to NULL to avoid this issue.

Addresses-Coverity: ("Uninitialized pointer read")
Fixes: 10652f39943e ("net/mlx5: Refactor ingress acl configuration")
