[PATCH] af_key: Add lock to key dump

2017-03-31 Thread Yuejie Shi
A dump may come in the middle of another dump, modifying its dump structure members. This race condition will result in NULL pointer dereference in kernel. So add a lock to prevent that race. Fixes: 83321d6b9872 ("[AF_KEY]: Dump SA/SP entries non-atomically") Signed-off-by: Yuejie Shi
