Subject: [rpcbind PATCH 0/6] rpcbind: various hardening fixes
Date: Thu,  3 Sep 2026 13:42:39 -0400	[thread overview]
Message-ID: <20260903174245.1213147-1-smayhew@redhat.com> (raw)

Various hardening fixes for rpcbind.  Many of these are related to
CALLIT/BCAST/INDIRECT processing, which in theory should be disabled
when --enable-rmtcalls was not passed to the configure script, except
currently that only prevents the forwarding port from being created.
Patch 3/6 addresses this by completely disabling remote call
functionality when --enable-rmtcalls is unset.

Scott Mayhew (6):
  rpcbind: only log failures in check_callit() if connection logging is
    enabled
  rpcbind: bound stats lists in rpcbs_getaddr() and rpcbs_rmtcall()
  rpcbind: fully disable remote calls when --enable-rmtcalls is unset
  rpcbind: restrict RPCBPROC_GETSTAT to loopback callers
  rpcbind: check for null netmask in addrmerge()
  rpcbind: only free the forward slot if the reply xid matched the
    request xid
