Subject: Fix: lttng_rotate_session does not handle socket close
X-Git-Tag: v2.12.0-rc1~621
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=1320cab14db79aad4429e9f207ba8fa27b52f498;hp=1320cab14db79aad4429e9f207ba8fa27b52f498;p=lttng-tools.git

Fix: lttng_rotate_session does not handle socket close

lttng_ctl_ask_sessiond may return 0 if the sessiond process is killed
or if its client socket is closed unexpectedly. This causes
lttng_rotate_session to assume a rotation command reply has
been received, resulting in a NULL pointer dereference later on.
