Re: [libvirt] [PATCH 3/4] Use a virFreeCallback on virNetSocket to ensure safe release

From: "Daniel P. Berrange"<berrange(a)redhat.com> When unregistering an I/O callback from a virNetSocket object, there is still a chance that an event may come in on the callback. In this case it is possible that the virNetSocket might have been freed already. Make use of a virFreeCallback when registering the I/O callbacks and hold a reference for the entire time the callback is set. * src/rpc/virnetsocket.c: Register a free function for the file handle watch * src/rpc/virnetsocket.h, src/rpc/virnetserverservice.c, src/rpc/virnetserverclient.c, src/rpc/virnetclient.c: Add a free function for the socket I/O watches --- src/rpc/virnetclient.c | 13 ++++++++++++- src/rpc/virnetserverclient.c | 13 ++++++++++++- src/rpc/virnetserverservice.c | 20 ++++++++++++++++++-- src/rpc/virnetsocket.c | 30 ++++++++++++++++++++++++++++-- src/rpc/virnetsocket.h | 3 ++- 5 files changed, 72 insertions(+), 7 deletions(-)
