From 37941ea17d3f8eb2f5ac2f59346fab9e8439271a Mon Sep 17 00:00:00 2001 From: Long Li Date: Wed, 16 Oct 2019 13:51:52 -0700 Subject: [PATCH] cifs: smbd: Return -EINVAL when the number of iovs exceeds SMBDIRECT_MAX_SGE While it's not friendly to fail user processes that issue more iovs than we support, at least we should return the correct error code so the user process gets a chance to retry with smaller number of iovs. Signed-off-by: Long Li Cc: stable@vger.kernel.org Signed-off-by: Steve French --- fs/cifs/smbdirect.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/cifs/smbdirect.c b/fs/cifs/smbdirect.c index 3c91fa9..64c5b87 100644 --- a/fs/cifs/smbdirect.c +++ b/fs/cifs/smbdirect.c @@ -1069,7 +1069,7 @@ static int smbd_post_send_data( if (n_vec > SMBDIRECT_MAX_SGE) { cifs_dbg(VFS, "Can't fit data to SGL, n_vec=%d\n", n_vec); - return -ENOMEM; + return -EINVAL; } sg_init_table(sgl, n_vec); -- 2.7.4
