From 7b5cc6ee6cf9001775c348bac09814a45f1276b7 Mon Sep 17 00:00:00 2001 From: Karol Swietlicki Date: Mon, 4 Feb 2008 22:31:04 -0800 Subject: [PATCH] uml: fix mconsole stop Bring back the functionality of stopping user mode linux with the help of mconsole. [jdike - the bug being fixed is that the mconsole file descriptor is already set O_NONBLOCK or not, depending on whether we want no blocking (the normal case) or we want blocking (when an mconsole stop is in effect), so the MSG_DONTWAIT is redundant in the normal case, and wrong when we want to block.] Signed-off-by: Karol Swietlicki Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/um/drivers/mconsole_user.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/arch/um/drivers/mconsole_user.c b/arch/um/drivers/mconsole_user.c index 430c024a19..13af2f03ed 100644 --- a/arch/um/drivers/mconsole_user.c +++ b/arch/um/drivers/mconsole_user.c @@ -83,9 +83,8 @@ int mconsole_get_request(int fd, struct mc_request *req) int len; req->originlen = sizeof(req->origin); - req->len = recvfrom(fd, &req->request, sizeof(req->request), - MSG_DONTWAIT, (struct sockaddr *) req->origin, - &req->originlen); + req->len = recvfrom(fd, &req->request, sizeof(req->request), 0, + (struct sockaddr *) req->origin, &req->originlen); if (req->len < 0) return 0; -- 2.39.5
