Some of the error messages in this function should have been virReportSystemError (since they have an errno they want to log), but were mistakenly written as netlinkError, which expects a libvirt error code instead. The result was that when one of the errors was encountered, "No error message provided" would be printed instead of something meaningful (see https://bugzilla.redhat.com/show_bug.cgi?id=816465 for an example). --- src/util/virnetlink.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/src/util/virnetlink.c b/src/util/virnetlink.c index 7017275..b2e9d51 100644 --- a/src/util/virnetlink.c +++ b/src/util/virnetlink.c @@ -238,8 +238,8 @@ virNetlinkEventCallback(int watch, if (length == 0) return; if (length < 0) { - netlinkError(errno, - "%s", _("nl_recv returned with error")); + virReportSystemError(errno, + "%s", _("nl_recv returned with error")); return; } @@ -349,28 +349,28 @@ virNetlinkEventServiceStart(void) srv->netlinknh = nl_handle_alloc(); if (!srv->netlinknh) { - netlinkError(errno, - "%s", _("cannot allocate nlhandle for virNetlinkEvent server")); + virReportSystemError(errno, + "%s", _("cannot allocate nlhandle for virNetlinkEvent server")); goto error_locked; } if (nl_connect(srv->netlinknh, NETLINK_ROUTE) < 0) { - netlinkError(errno, - "%s", _("cannot connect to netlink socket")); + virReportSystemError(errno, + "%s", _("cannot connect to netlink socket")); goto error_server; } fd = nl_socket_get_fd(srv->netlinknh); if (fd < 0) { - netlinkError(errno, - "%s", _("cannot get netlink socket fd")); + virReportSystemError(errno, + "%s", _("cannot get netlink socket fd")); goto error_server; } if (nl_socket_set_nonblocking(srv->netlinknh)) { - netlinkError(errno, "%s", - _("cannot set netlink socket nonblocking")); + virReportSystemError(errno, "%s", + _("cannot set netlink socket nonblocking")); goto error_server; } -- 1.7.10
