Subject: Fix: use MT-safe strtok_r in multithreaded context
X-Git-Tag: v2.11.6~1
X-Git-Url: https://git.liburcu.org/?a=commitdiff_plain;h=81d58936ceb13b491c1bceffae0219f275b38fc2;hp=81d58936ceb13b491c1bceffae0219f275b38fc2;p=lttng-tools.git

Fix: use MT-safe strtok_r in multithreaded context

append_list_to_probes uses the non-multithread-safe "strtok" while in
multithreaded context.

It is called by modprobe_lttng_data(), which is called from
init_kernel_tracer().

init_kernel_tracer is used from main() after other threads are created,
and also from process_client_msg() when a user attempts to interact with
the kernel domain if the kernel tracer has not yet been successfully
initialized.

Fixed by using the MT-safe strtok_r() instead.
