+Subject: [PATCH] Fix DoS vulnerability in libtirpc
+
+Currently svc_run does not handle poll timeout and rendezvous_request
+does not handle EMFILE error returned from accept(2 as it used to.
+These two missing functionality were removed by commit b2c9430f46c4.
+
+The effect of not handling poll timeout allows idle TCP conections
+to remain ESTABLISHED indefinitely. When the number of connections
+reaches the limit of the open file descriptors (ulimit -n) then
+accept(2) fails with EMFILE. Since there is no handling of EMFILE
+error this causes svc_run() to get in a tight loop calling accept(2).
+This resulting in the RPC service of svc_run is being down, it's
+no longer able to service any requests.
+
+RPC service rpcbind, statd and mountd are effected by this
+problem.
+
+Fix by enhancing rendezvous_request to keep the number of
+SVCXPRT conections to 4/5 of the size of the file descriptor
+table. When this thresold is reached, it destroys the idle
+TCP connections or destroys the least active connection if
+no idle connnction was found.
+
+Fixes: 44bf15b8 rpcbind: don't use obsolete svc_fdset interface of libtirpc
