FAILED: patch "[PATCH] net/mlx5e: Fix nullptr in mlx5e_tc_add_fdb_flow()" failed to apply to 4.19-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From fe7738eb3ca3631a75844e790f6cb576c0fe7b00 Mon Sep 17 00:00:00 2001 From: Dima Chumak <dchumak(a)nvidia.com> Date: Mon, 26 Apr 2021 15:16:26 +0300 Subject: [PATCH] net/mlx5e: Fix nullptr in mlx5e_tc_add_fdb_flow() The result of __dev_get_by_index() is not checked for NULL, which then passed to mlx5e_attach_encap() and gets dereferenced. Also, in case of a successful lookup, the net_device reference count is not incremented, which may result in net_device pointer becoming invalid at any time during mlx5e_attach_encap() execution. Fix by using dev_get_by_index(), which does proper reference counting on the net_device pointer. Also, handle nullptr return value when mirred device is not found. It's safe to call dev_put() on the mirred net_device pointer, right after mlx5e_attach_encap() call, because it's not being saved/copied down the call chain.

FAILED: patch "[PATCH] net/mlx5e: Fix nullptr in mlx5e_tc_add_fdb_flow()" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From fe7738eb3ca3631a75844e790f6cb576c0fe7b00 Mon Sep 17 00:00:00 2001 From: Dima Chumak <dchumak(a)nvidia.com> Date: Mon, 26 Apr 2021 15:16:26 +0300 Subject: [PATCH] net/mlx5e: Fix nullptr in mlx5e_tc_add_fdb_flow() The result of __dev_get_by_index() is not checked for NULL, which then passed to mlx5e_attach_encap() and gets dereferenced. Also, in case of a successful lookup, the net_device reference count is not incremented, which may result in net_device pointer becoming invalid at any time during mlx5e_attach_encap() execution. Fix by using dev_get_by_index(), which does proper reference counting on the net_device pointer. Also, handle nullptr return value when mirred device is not found. It's safe to call dev_put() on the mirred net_device pointer, right after mlx5e_attach_encap() call, because it's not being saved/copied down the call chain.
