Subject: Fix: consumerd(64/32)_lib_dir can be NULL
X-Git-Tag: v2.11.0-rc1~424
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=46b23495cca0157ed2d4e607a7e4b801635eaea2;hp=46b23495cca0157ed2d4e607a7e4b801635eaea2;p=lttng-tools.git

Fix: consumerd(64/32)_lib_dir can be NULL

Reproducer:
lttng-sessiond \
    --consumerd32-path=/usr/local/lib/lttng/libexec/lttng-consumerd \
    --consumerd64-path=/usr/local/lib/lttng/libexec/lttng-consumerd

lttng create
lttng enable-event -u -a

On a 64bit machine the invocation of the 64bit consumerd will not fail
since its libdir is populated by sessiond_config_init but will segfault on
spawning of the 32 bit consumerd when performing the check of libdir
value.

On a 32bit machine the opposite will happen.
