mainline inclusion from mainline-5.12-rc1 commit dc9c9e72 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4MFVB CVE: NA ------------------------------------------------- Currently the driver doesn't drop a packet which can't be sent by tun (e.g bad packet). In this case, the driver will always process the same packet lead to the tx queue stuck. To fix this issue: 1. in the case of persistent failure (e.g bad packet), the driver can skip this descriptor by ignoring the error. 2. in the case of transient failure (e.g -ENOBUFS, -EAGAIN and -ENOMEM), the driver schedules the worker to try again.

mainline inclusion from mainline-v5.2-rc1 commit 0e14ef38 category: bugfix bugzilla: NA CVE: NA ----------------------------------------------------------------------- sm4_aesni_avx_crypt8() sets up the frame pointer (which includes pushing RBP) before doing a conditional sibling call to sm4_aesni_avx_crypt4(), which sets up an additional frame pointer. Things will not go well when sm4_aesni_avx_crypt4() pops only the innermost single frame pointer and then tries to return to the outermost frame pointer. Sibling calls need to occur with an empty stack frame. Do the conditional sibling call *before* setting up the stack pointer.

mainline inclusion from mainline-v5.15.4 commit 5b2efa2b category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4A82K?from=project-issue CVE: NA ------------------------------------------------------------------- Like the implementation of AESNI/AVX, this patch adds an accelerated implementation of AESNI/AVX2. In terms of code implementation, by reusing AESNI/AVX mode-related codes, the amount of code is greatly reduced. From the benchmark data, it can be seen that when the block size is 1024, compared to AVX acceleration, the performance achieved by AVX2 has increased by about 70%, it is also 7.7 times of the pure software implementation of sm4-generic. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O. Saarinen at: https://github.com/mjosaarinen/sm4ni This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. Benchmark on Intel i5-6200U 2.30GHz, performance data of three implementation methods, pure software sm4-generic, aesni/avx acceleration, and aesni/avx2 acceleration, the data comes from the 218 mode and 518 mode of tcrypt.

hulk inclusion category: feature bugzilla: 9511, https://gitee.com/openeuler/kernel/issues/I4IHL1 CVE: NA ------------------------------------------------- Consider two IPVlan devices are set up on the same master, when they communicate with each other by TCP, the receive part is too fast to make the send packets coalesced, so in this case, the performace is not as good as we expect. This patch introduces a local xmit queue for l2e mode, when the packets are sent to the IPVlan devices of the same master, the packets will be cloned and added to the local xmit queue, this operation can make the send packets coalesced and improve the TCP performace in this case.

hulk inclusion category: feature bugzilla: 9511, https://gitee.com/openeuler/kernel/issues/I4IHL1 CVE: NA ------------------------------------------------- In a typical IPvlan L2 setup where master is in default-ns and each slave is into different (slave) ns. In this setup, if master and slaves in different net, egress packet processing for traffic originating from slave-ns can't be forwarded to master or other machine whose ip in the same net with master, and they can't be forwarded to other interface in default-ns. This patch introuce a new mode l2e for ipvlan to realize above goals, and it won't affect the original l2, l3, l3s mode. As the ip tool doesn't support l2e mode, We use module param "ipvlan_default_mode" to set the default work mode. 0 for l2 mode, 1 for l3, 2 for l2e, 3 for l3s, others invalid now.

Since the rdev current state is 'spare', read/write bio can be issued to the disk. Then we set the other disk (/dev/sdb) faulty. Since the raid array is now in degraded state and /dev/sdb is the only 'In_sync' disk, raid1_error() will return but without set faulty success. However, that can interrupt the recovery action and md_check_recovery will try to call remove_and_add_spares() to remove the spare disk. And the race condition between remove_and_add_spares() and raid1_write_request() in follow can cause NULL pointer dereference for conf->mirrors[i].rdev: raid1_write_request() md_check_recovery raid1_error() rcu_read_lock() rdev != NULL !test_bit(Faulty, &rdev->flags) conf->recovery_disabled= mddev->recovery_disabled; return busy remove_and_add_spares raid1_remove_disk rdev->nr_pending == 0 atomic_inc(&rdev->nr_pending); rcu_read_unlock() p->rdev=NULL conf->mirrors[i].rdev->data_offset NULL pointer deref!!! if (!test_bit(RemoveSynchronized, &rdev->flags)) synchronize_rcu(); p->rdev=rdev To fix the race condition, we add a new flag 'WantRemove' for rdev. Before access conf->mirrors[i].rdev, we need to ensure the rdev without 'WantRemove' bit.

The result is that privileged userspace applications have a priority boost with respect to audit as they are not bound by the same audit queue throttling as the other tasks on the system. This patch attempts to restore some balance to the system when under audit pressure by blocking these privileged userspace tasks after they have finished their audit processing, and dropped the audit control mutex, but before they return to userspace.

With the kernel thread blocked it is possible that the audit queue could grow unbounded as certain audit record generating events must be exempt from the queue limits else the system enter a deadlock state. This patch resolves this problem by lowering the kernel thread's socket sending timeout from MAX_SCHEDULE_TIMEOUT to HZ/10 and tweaks the kauditd_send_queue() function to better manage the various audit queues when connection problems occur between the kernel and the audit daemon. With this patch, the backlog may temporarily grow beyond the defined limits when the audit daemon is stopped and the system is under heavy audit pressure, but kauditd_thread() will continue to make progress and drain the queues as it would for other connection problems. For example, with the audit daemon put into a stopped state and the system configured to audit every syscall it was still possible to shutdown the system without a kernel panic, deadlock, etc.; granted, the system was slow to shutdown but that is to be expected given the extreme pressure of recording every syscall. The timeout value of HZ/10 was chosen primarily through experimentation and this developer's "gut feeling". There is likely no one perfect value, but as this scenario is limited in scope (root privileges would be needed to send SIGSTOP to the audit daemon), it is likely not worth exposing this as a tunable at present. This can always be done at a later date if it proves necessary.
