Subject: Fix: do not repurpose iterator while it is being used
X-Git-Tag: v2.10.6~6
X-Git-Url: http://git.lttng.org/?a=commitdiff_plain;h=88c6cf5e08792a86853a27b94944dc9df1d3a330;hp=88c6cf5e08792a86853a27b94944dc9df1d3a330;p=lttng-tools.git

Fix: do not repurpose iterator while it is being used

The hash table iteration uses an iterator that needs to stay valid for
the next loop. Using that same iterator variable in a nested lookup in a
different hash table leads to segmentation fault.

This is a 2.10-specific instance of the issue affecting
bind_trigger_to_matching_channels() which was found in the
master and 2.11 branches. This one affects
handle_notification_thread_command_register_trigger().
