Message-Id: <20230427-scan-build-v2-3-bb96a6e6a33b@codewreck.org> Date: Wed, 03 May 2023 16:49:27 +0900 From: Dominique Martinet <asmadeus@...ewreck.org> To: Eric Van Hensbergen <ericvh@...il.com>, Latchesar Ionkov <lucho@...kov.net>, Christian Schoenebeck <linux_oss@...debyte.com>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> Cc: Simon Horman <simon.horman@...igine.com>, v9fs@...ts.linux.dev, linux-kernel@...r.kernel.org, netdev@...r.kernel.org, Dominique Martinet <asmadeus@...ewreck.org> Subject: [PATCH v2 3/5] 9p: virtio: make sure 'offs' is initialized in zc_request Similarly to the previous patch: offs can be used in handle_rerrors without initializing on small payloads; in this case handle_rerrors will not use it because of the size check, but it doesn't hurt to make sure it is zero to please scan-build. This fixes the following warning: net/9p/trans_virtio.c:539:3: warning: 3rd function call argument is an uninitialized value [core.CallAndMessage] handle_rerror(req, in_hdr_len, offs, in_pages); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reviewed-by: Simon Horman <simon.horman@...igine.com> Signed-off-by: Dominique Martinet <asmadeus@...ewreck.org> --- net/9p/trans_virtio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/9p/trans_virtio.c b/net/9p/trans_virtio.c index 2c9495ccda6b..f3f678289423 100644 --- a/net/9p/trans_virtio.c +++ b/net/9p/trans_virtio.c @@ -428,7 +428,7 @@ p9_virtio_zc_request(struct p9_client *client, struct p9_req_t *req, struct page **in_pages = NULL, **out_pages = NULL; struct virtio_chan *chan = client->trans; struct scatterlist *sgs[4]; - size_t offs; + size_t offs = 0; int need_drop = 0; int kicked = 0; -- 2.39.2
