Re: [libvirt] [PATCH] rpc: Fix client crash on connection close

A multi-threaded client with event loop may crash if one of its threads closes a connection while event loop is in the middle of sending keep-alive message (either request or response). The right place for it is inside virNetClientIOEventLoop() between poll() and virNetClientLock(). We should only close a connection directly if no-one is using it and defer the closing to the last user otherwise. So far we only did so if the close was initiated by keep-alive timeout. --- src/rpc/virnetclient.c | 18 ++++-------------- 1 files changed, 4 insertions(+), 14 deletions(-)
