Subject: [PATCH AUTOSEL 5.4 106/108] svcrdma: Fix leak of transport addresses
Date: Sat, 11 Apr 2020 19:09:41 -0400 [thread overview]
Message-ID: <20200411230943.24951-106-sashal@kernel.org> (raw)
In-Reply-To: <20200411230943.24951-1-sashal@kernel.org>
From: Chuck Lever <chuck.lever@oracle.com>
[ Upstream commit 1a33d8a284b1e85e03b8c7b1ea8fb985fccd1d71 ]
Kernel memory leak detected:
unreferenced object 0xffff888849cdf480 (size 8):
comm "kworker/u8:3", pid 2086, jiffies 4297898756 (age 4269.856s)
hex dump (first 8 bytes):
30 00 cd 49 88 88 ff ff 0..I....

Introduce a call to xprt_rdma_free_addresses() similar to the way
that the TCP backchannel releases a transport's peer address
strings.
Fixes: 5d252f90a800 ("svcrdma: Add class for RDMA backwards direction transport")
