Subject: Fix: FDs are added to payload despite not being received
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=b3ba184e31e0e5cc67e7d7fb6594096a068ad1be;hp=b3ba184e31e0e5cc67e7d7fb6594096a068ad1be;p=lttng-tools.git

Fix: FDs are added to payload despite not being received

`lttcomm_recv_fds_unix_sock_non_block` can return zero on EAGAIN.

It is important not to add the raw_fds array to the payload in such case
since concretely no FDs have been received.
