Subject: Fix: fd leak in process client msg error path
X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=36134aa184c8ed8f67a197d66d1310425abbf1ce

Fix: fd leak in process client msg error path

The process_client_msg() function could return an error but no
sock_error. In any case, we have to close the socket since a TODO is
still there indicating that we need to reply to the client to inform of
the error.

Issue 1019920 of coverity scan.
