Description
Error:
lttng-sessiond: ust-app.c:4520: reply_ust_register_channel: Assertion `chan_reg' failed.
Aborted
How to reproduce:
lttng create
lttng enable-channel mychan1 -u --buffers-uid
lttng enable-channel mychan2 -u --buffers-uid
lttng enable-event -u -a -c mychan1
lttng enable-event -u -a -c mychan2
lttng start
use UST hello test program, run twice:
./hello
./hello
At the second execution of "hello", we get the assert in sessiond. It's possibly a mixup in the channel IDs given to per-UID buffers within sessiond.
