[PATCH kernel-4.19 1/2] mmap: userswap: fix memory leak in do_mmap

From: Xiongfeng Wang <wangxiongfeng2(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4AHP2 CVE: NA ------------------------------------------------- When userswap is enabled, the memory pointed by 'pages' is not freed in abnormal branch in do_mmap(). To fix the issue and keep do_mmap() mostly unchanged, we rename do_mmap() to __do_mmap() and extract the memory alloc and free code out of __do_mmap(). When __do_mmap() returns a error value, we goto the error label to free the memory.

[PATCH openEuler-21.03] drm: Lock pointer access in drm_master_release()

18 Oct '21

From: Desmond Cheong Zhi Xi <desmondcheongzx(a)gmail.com> stable inclusion from stable-v5.10.44 commit aa8591a58cbd2986090709e4202881f18e8ae30e bugzilla:https://bugzilla.openeuler.org/show_bug.cgi?id=435 CVE: NA ------------------------------------------------- commit c336a5ee984708db4826ef9e47d184e638e29717 upstream. This patch eliminates the following smatch warning: drivers/gpu/drm/drm_auth.c:320 drm_master_release() warn: unlocked access 'master' (line 318) expected lock '&dev->master_mutex' The 'file_priv->master' field should be protected by the mutex lock to '&dev->master_mutex'. This is because other processes can concurrently modify this field and free the current 'file_priv->master' pointer. This could result in a use-after-free error when 'master' is dereferenced in subsequent function calls to 'drm_legacy_lock_master_cleanup()' or to 'drm_lease_revoke()'. An example of a scenario that would produce this error can be seen from a similar bug in 'drm_getunique()' that was reported by Syzbot: https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f8… In the Syzbot report, another process concurrently acquired the device's master mutex in 'drm_setmaster_ioctl()', then overwrote 'fpriv->master' in 'drm_new_set_master()'. The old value of 'fpriv->master' was subsequently freed before the mutex was unlocked.

[PATCH openEuler-1.0-LTS 1/2] io_uring: hold uring_lock while completing failed polled io in io_wq_submit_work()
by Yang Yingliang 15 Oct '21

15 Oct '21

From: Xiaoguang Wang <xiaoguang.wang(a)linux.alibaba.com> mainline inclusion from mainline-5.11-rc1 commit c07e6719511e77c4b289f62bfe96423eb6ea061d category: bugfix bugzilla: 182869 CVE: NA --------------------------- io_iopoll_complete() does not hold completion_lock to complete polled io, so in io_wq_submit_work(), we can not call io_req_complete() directly, to complete polled io, otherwise there maybe concurrent access to cqring, defer_list, etc, which is not safe. Commit dad1b1242fd5 ("io_uring: always let io_iopoll_complete() complete polled io") has fixed this issue, but Pavel reported that IOPOLL apart from rw can do buf reg/unreg requests( IORING_OP_PROVIDE_BUFFERS or IORING_OP_REMOVE_BUFFERS), so the fix is not good. Given that io_iopoll_complete() is always called under uring_lock, so here for polled io, we can also get uring_lock to fix this issue.

[PATCH kernel-4.19] net_sched: remove need_resched() from qdisc_run()
by Yang Yingliang 15 Oct '21

15 Oct '21

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v5.5-rc1 commit b60fa1c5d01a10e358c509b904d4bead6114d593 category: bugfix bugzilla: 182865 CVE: NA ------------------------------------------------- The introduction of this schedule point was done in commit 2ba2506ca7ca ("[NET]: Add preemption point in qdisc_run") at a time the loop was not bounded. Then later in commit d5b8aa1d246f ("net_sched: fix dequeuer fairness") we added a limit on the number of packets. Now is the time to remove the schedule point, since the default limit of 64 packets matches the number of packets a typical NAPI poll can process in a row. This solves a latency problem for most TCP receivers under moderate load : 1) host receives a packet. NET_RX_SOFTIRQ is raised by NIC hard IRQ handler 2) __do_softirq() does its first loop, handling NET_RX_SOFTIRQ and calling the driver napi->loop() function 3) TCP stores the skb in socket receive queue: 4) TCP calls sk->sk_data_ready() and wakeups a user thread waiting for EPOLLIN (as a result, need_resched() might now be true) 5) TCP cooks an ACK and sends it. 6) qdisc_run() processes one packet from qdisc, and sees need_resched(), this raises NET_TX_SOFTIRQ (even if there are no more packets in the qdisc) Then we go back to the __do_softirq() in 2), and we see that new softirqs were raised. Since need_resched() is true, we end up waking ksoftirqd in this path : if (pending) { if (time_before(jiffies, end) && !need_resched() && --max_restart) goto restart; wakeup_softirqd(); } So we have many wakeups of ksoftirqd kernel threads, and more calls to qdisc_run() with associated lock overhead. Note that another way to solve the issue would be to change TCP to first send the ACK packet, then signal the EPOLLIN, but this changes P99 latencies, as sending the ACK packet can add a long delay.
