Subject: [nft PATCH 09/10] netlink_delinearize: Fix suspicious calloc() call
Date: Fri, 11 Jun 2021 18:41:03 +0200 [thread overview]
Message-ID: <20210611164104.8121-10-phil@nwl.cc> (raw)
In-Reply-To: <20210611164104.8121-1-phil@nwl.cc>
Parameter passed to sizeof() was wrong. While being at it, replace the
whole call with xmalloc_array() which takes care of error checking.
Fixes: 913979f882d13 ("src: add expression handler hashtable")
Signed-off-by: Phil Sutter <phil@nwl.cc>
