Subject: Fix: space left in buffer may be uninitilized on capacity increase
X-Git-Tag: v2.11.0-rc1~558
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=1c6def05e37f4a8a828a94aa0ca0e6236877f26f;hp=1c6def05e37f4a8a828a94aa0ca0e6236877f26f

Fix: space left in buffer may be uninitilized on capacity increase

In the following case of dynamic buffer resize:

|---------|---------------------|------------------------|
          ^                     ^                        ^
 (a) original_size     (b) original_capacity     (c) new_capacity

The code (correctly) assumes that the space between b and c is
zero-initialized. However, the space between a and b will be left
uninitialized.
