[PATCH OLK-5.10] KVM: nVMX: Set LDTR to its architecturally defined value on nested VM-Exit
by 任敏敏(联通集团联通数字科技有限公司本部) 10 Apr '23

10 Apr '23

From: Sean Christopherson <seanjc(a)google.com> stable inclusion from stable-v5.15 commit afc8de0118be84f4058b9977d481aeb3e0758dbb category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6SN2F CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------ commit afc8de0118be84f4058b9977d481aeb3e0758dbb upstream Set L1's LDTR on VM-Exit per the Intel SDM: The host-state area does not contain a selector field for LDTR. LDTR is established as follows on all VM exits: the selector is cleared to 0000H, the segment is marked unusable and is otherwise undefined (although the base address is always canonical). This is likely a benign bug since the LDTR is unusable, as it means the L1 VMM is conditioned to reload its LDTR in order to function properly on bare metal.

[PATCH openEuler-1.0-LTS 01/19] alarmtimer: Prevent starvation by small intervals and SIG_IGN
by Yongqiang Liu 07 Apr '23

07 Apr '23

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from stable-v4.19.274 commit d6a300076d11a6e27b4d4f7fd986ec66ee97a3e1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6TIG1 CVE: NA -------------------------------- commit d125d1349abeb46945dc5e98f7824bf688266f13 upstream. syzbot reported a RCU stall which is caused by setting up an alarmtimer with a very small interval and ignoring the signal. The reproducer arms the alarm timer with a relative expiry of 8ns and an interval of 9ns. Not a problem per se, but that's an issue when the signal is ignored because then the timer is immediately rearmed because there is no way to delay that rearming to the signal delivery path. See posix_timer_fn() and commit 58229a189942 ("posix-timers: Prevent softirq starvation by small intervals and SIG_IGN") for details. The reproducer does not set SIG_IGN explicitely, but it sets up the timers signal with SIGCONT. That has the same effect as explicitely setting SIG_IGN for a signal as SIGCONT is ignored if there is no handler set and the task is not ptraced. The log clearly shows that: [pid 5102] --- SIGCONT {si_signo=SIGCONT, si_code=SI_TIMER, si_timerid=0, si_overrun=316014, si_int=0, si_ptr=NULL} --- It works because the tasks are traced and therefore the signal is queued so the tracer can see it, which delays the restart of the timer to the signal delivery path. But then the tracer is killed: [pid 5087] kill(-5102, SIGKILL <unfinished ...> ... ./strace-static-x86_64: Process 5107 detached and after it's gone the stall can be observed: syzkaller login: [ 79.439102][ C0] hrtimer: interrupt took 68471 ns [ 184.460538][ C1] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: ...

That's accurate vs. the overrun accounting, but slightly inaccurate vs. timer_gettimer(2). The comment in that function says what needs to be done and there was a fix available for the regular userspace induced SIG_IGN mechanism, but that did not work due to the implicit ignore for SIGCONT and similar signals. This needs to be worked on, but for now the only available workaround is to do exactly what posix_timer_fn() does: Increase the interval of self-rearming timers, which have their signal ignored, to at least a jiffie. Interestingly this has been fixed before via commit ff86bf0c65f1 ("alarmtimer: Rate limit periodic intervals") already, but that fix got lost in a later rework.

[PATCH openEuler-22.03-LTS] net/smc: align the connect behaviour with TCP
by Litao Jiao 07 Apr '23

mainline inclusion from mainline-v5.19.rc1 commit 3aba103006bcc4a7472b7c9506b3bc065ffb7992 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6TK1U CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Connect with O_NONBLOCK will not be completed immediately and returns -EINPROGRESS. It is possible to use selector/poll for completion by selecting the socket for writing. After select indicates writability, a second connect function call will return 0 to indicate connected successfully as TCP does, but smc returns -EISCONN. Use socket state for smc to indicate connect state, which can help smc aligning the connect behaviour with TCP.

[PATCH openEuler-1.0-LTS 01/13] mm: mem_reliable: Initialize reliable_nr_page when mm_init()
by Yongqiang Liu 07 Apr '23

07 Apr '23

From: Ma Wupeng <mawupeng1(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6RKHX CVE: NA -------------------------------- After the fork operation, it is erroneous for the child process to have a reliable page size twice that of its parent process. Upon examining the mm_struct structure, it was discovered that reliable_nr_page should be initialized to 0, similar to how RSS is initialized during mm_init(). This particular problem that arises during forking is merely one such example. To resolve this issue, it is recommended to set reliable_nr_page to 0 during the mm_init() operation.

[PATCH openEuler-1.0-LTS 1/5] loop: Add parm check in loop_control_ioctl
by Yongqiang Liu 07 Apr '23

07 Apr '23

From: Zhong Jinghua <zhongjinghua(a)huawei.com> hulk inclusion category: bugfix bugzilla: 188586, https://gitee.com/openeuler/kernel/issues/I6TFPJ CVE: NA ---------------------------------------- We found that in loop_control_ioctl, the kernel panic can be easily caused: 1. syscall(__NR_ioctl, r[1], 0x4c80, 0x80000200000ul); Create a loop device 0x80000200000ul. In fact, in the code, it is used as the first_minor number, and the first_minor number is 0. So the created loop device number is 7:0. 2. syscall(__NR_ioctl, r[2], 0x4c80, 0ul); Create a loop device 0x0ul. Since the 7:0 device has been created in 1, add_disk will fail because the major and first_minor numbers are consistent. 3. syscall(__NR_ioctl, r[5], 0x4c81, 0ul); Delete the device that failed to create, the kernel panics. Panic like below: BUG: KASAN: null-ptr-deref in device_del+0xb3/0x840 drivers/base/core.c:3107 Call Trace: kill_device drivers/base/core.c:3079 [inline] device_del+0xb3/0x840 drivers/base/core.c:3107 del_gendisk+0x463/0x5f0 block/genhd.c:971 loop_remove drivers/block/loop.c:2190 [inline] loop_control_ioctl drivers/block/loop.c:2289 [inline] The stack like below: Create loop device: loop_control_ioctl loop_add add_disk device_add_disk bdi_register bdi_register_va device_create device_create_groups_vargs device_add kfree(dev->p); dev->p = NULL; Remove loop device: loop_control_ioctl loop_remove del_gendisk device_del kill_device if (dev->p->dead) // p is null Fix it by adding a check for parm.

[PATCH openEuler-1.0-LTS] Fix double fget() in vhost_net_set_backend()
by Yongqiang Liu 06 Apr '23

06 Apr '23

From: Al Viro <viro(a)zeniv.linux.org.uk> stable inclusion from stable-v4.19.245 commit 6ca70982c646cc32e458150ee7f2530a24369b8c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6T1EY CVE: CVE-2023-1838 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit fb4554c2232e44d595920f4d5c66cf8f7d13f9bc upstream. Descriptor table is a shared resource; two fget() on the same descriptor may return different struct file references. get_tap_ptr_ring() is called after we'd found (and pinned) the socket we'll be using and it tries to find the private tun/tap data structures associated with it. Redoing the lookup by the same file descriptor we'd used to get the socket is racy - we need to same struct file. Thanks to Jason for spotting a braino in the original variant of patch - I'd missed the use of fd == -1 for disabling backend, and in that case we can end up with sock == NULL and sock != oldsock.
