Subject: [PATCH bpf-next v2 0/4] Add some 'malloc' failure checks
Date: Fri, 10 May 2024 17:57:59 +0800	[thread overview]
Message-ID: <20240510095803.472840-1-kunwu.chan@linux.dev> (raw)

From: Kunwu Chan <chentao@kylinos.cn>

The "malloc" call may not be successful.Add the malloc
failure checking to avoid possible null dereference.

Changes since v1 [1]:
        - As Daniel Borkmann suggested, change patch 4/4 only
        - Other 3 patches no changes.
