Linus Lüssing 454594f3b9 Revert "bridge: only expire the mdb entry when query is received" ... While this commit was a good attempt to fix issues occuring when no multicast querier is present, this commit still has two more issues: 1) There are cases where mdb entries do not expire even if there is a querier present. The bridge will unnecessarily continue flooding multicast packets on the according ports. 2) Never removing an mdb entry could be exploited for a Denial of Service by an attacker on the local link, slowly, but steadily eating up all memory. Actually, this commit became obsolete with "bridge: disable snooping if there is no querier" (b00589af3b) which included fixes for a few more cases. Therefore reverting the following commits (the commit stated in the commit message plus three of its follow up fixes): ==================== Revert "bridge: update mdb expiration timer upon reports." This reverts commit f144febd93. Revert "bridge: do not call setup_timer() multiple times" This reverts commit 1faabf2aab. Revert "bridge: fix some kernel warning in multicast timer" This reverts commit c7e8e8a8f7. Revert "bridge: only expire the mdb entry when query is received" This reverts commit 9f00b2e7cf. ==================== CC: Cong Wang <amwang@redhat.com> Signed-off-by: Linus Lüssing <linus.luessing@web.de> Reviewed-by: Vlad Yasevich <vyasevich@gmail.com> Signed-off-by: David S.
