From: Jérémie Galarneau Date: Fri, 5 May 2017 20:07:43 +0000 (-0400) Subject: Fix: use of uninitialized channel attributes in client X-Git-Tag: v2.10.0-rc1~6 X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=c1e4642cd27bd5b70c0eca1011d9e452bd24f018 Fix: use of uninitialized channel attributes in client The channel attributes used to retrieve the defaults to use are not zero-initialized which is a problem now that the extended pointer is used to determine whether or not the structure was allocated on stack by the user (for backward compatibility) or dynamically using the new lttng_channel_create() interface.
