It does handle RTM_GETLINK. According to libnl docu- +mentation (http://www.infradead.org/~tgr/libnl/doc/route.html) +RTM_DELLINK can be sent by the kernel, but RTM_GETLINK cannot. +There was likely a mixup in the original implementation, so this +change replaces handling for RTM_GETLINK with RTM_DELLINK. + +Testing and Verification Instructions: + 1. Use ip-link to add and remove a VLAN interface and verify + that mDNSResponder handles the deleted link. + +Upstream-Status: Submitted [dts@apple.com] + +Signed-off-by: Nate Karstens <nate.karstens@garmin.com> +--- + mDNSPosix/mDNSPosix.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/mDNSPosix/mDNSPosix.c b/mDNSPosix/mDNSPosix.c +index 798ab10..a8a57df 100644 +--- a/mDNSPosix/mDNSPosix.c ++++ b/mDNSPosix/mDNSPosix.c +@@ -1163,7 +1163,7 @@ mDNSlocal void ProcessRoutingNotification(int sd, GenLinkedList *change + #endif + + // Process the NetLink message +- if (pNLMsg->nlmsg_type == RTM_GETLINK || pNLMsg->nlmsg_type == RTM_NEWLINK) ++ if (pNLMsg->nlmsg_type == RTM_DELLINK || pNLMsg->nlmsg_type == RTM_NEWLINK) + AddInterfaceIndexToList(changedInterfaces, ((struct ifinfomsg*) NLMSG_DATA(pNLMsg))->ifi_index); + else if (pNLMsg->nlmsg_type == RTM_DELADDR || pNLMsg->nlmsg_type == RTM_NEWADDR) + AddInterfaceIndexToList(changedInterfaces, ((struct ifaddrmsg*) NLMSG_DATA(pNLMsg))->ifa_index); +-- +2.17.1 + |
