[PATCH 5.4] net_sched: prevent NULL dereference if default qdisc setup failed

by Pratyush Yadav

If qdisc_create_dflt() fails, it returns NULL. With CONFIG_NET_SCHED enabled, the check qdisc != &noop_qdisc passes and qdisc will be passed to qdisc_hash_add(), which dereferences it. This assignment was present in the upstream commit 5891cd5ec46c2 ("net_sched: add __rcu annotation to netdev->qdisc") but was missed in the backport 22d95b5449249 ("net_sched: add __rcu annotation to netdev->qdisc"), perhaps due to merge conflicts. dev->qdisc is &noop_qdisc by default and if qdisc_create_dflt() fails, this assignment will make sure qdisc == &noop_qdisc and no NULL dereference will take place. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc. Fixes: 22d95b5449249 ("net_sched: add __rcu annotation to netdev->qdisc") Signed-off-by: Pratyush Yadav <ptyadav(a)amazon.de> --- As usual, this was found by our static code analysis bot.
