Subject: Fix: bad file descriptors on close after rotation error
X-Git-Tag: v2.8.0~28
X-Git-Url: https://git.liburcu.org/?a=commitdiff_plain;h=38119c1a313ba870529b1bb1ea0f842a6f8c5572;p=lttng-tools.git

Fix: bad file descriptors on close after rotation error

Ensure we don't try to close output stream file descriptors twice when a
trace file rotation error occurs (once at tracefile rotation, once when
closing the stream). Set the fd value to -1 after the first close to
ensure we don't try to close it again.
