Davide Caratti 0f74a071ae net/sched: sch_taprio: ensure to reset/destroy all child qdiscs ... [ Upstream commit 698285da79f5b0b099db15a37ac661ac408c80eb ] taprio_graft() can insert a NULL element in the array of child qdiscs. As a consquence, taprio_reset() might not reset child qdiscs completely, and taprio_destroy() might leak resources. Fix it by ensuring that loops that iterate over q->qdiscs[] don't end when they find the first NULL item. Fixes: 44d4775ca518 ("net/sched: sch_taprio: reset child qdiscs before freeing them") Fixes: 5a781ccbd19e ("tc: Add support for configuring the taprio scheduler") Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Davide Caratti <dcaratti@redhat.com> Link: https://lore.kernel.org/r/13edef6778fef03adc751582562fba4a13e06d6a.1608240532.git.dcaratti@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-04-12 12:51:10 +08:00
