[PATCH openEuler-1.0-LTS] net/sched: initialize noop_qdisc owner
by Zhengchao Shao 29 Jul '24

29 Jul '24

From: Johannes Berg <johannes.berg(a)intel.com> mainline inclusion from mainline-v6.10-rc4 commit 44180feaccf266d9b0b28cc4ceaac019817deb5c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAG4FI Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- When the noop_qdisc owner isn't initialized, then it will be 0, so packets will erroneously be regarded as having been subject to recursion as long as only CPU 0 queues them. For non-SMP, that's all packets, of course. This causes a change in what's reported to userspace, normally noop_qdisc would drop packets silently, but with this change the syscall returns -ENOBUFS if RECVERR is also set on the socket. Fix this by initializing the owner field to -1, just like it would be for dynamically allocated qdiscs by qdisc_alloc().
