Subject: [PATCH 0/2] sunrpc: fix handling of rq_bvec array in svc_rqst
Date: Wed, 08 Oct 2025 14:58:51 -0400 [thread overview]
Message-ID: <20251008-rq_bvec-v1-0-7f23d32d75e5@kernel.org> (raw)
I've seen this message pop intermittently on some knfsd servers:
rpc-srv/tcp: nfsd: sent 1045870 when sending 1045868 bytes - shutting down socket
Unfortunately, I've not been able to reproduce this on my own, but I've
noticed a bug that could cause this.
The first patch in this series fixes a bug in rq_bvec handling I noticed
by inspection. The second patch adds a slot to rq_bvec to account for
the slot used for the TCP record marker.
