[PATCH openEuler-21.03 1/2] mm: add pin memory method for checkpoint add restore
by hejingxian＠huawei.com 02 Mar '21

02 Mar '21

From: Jingxian He <hejingxian(a)huawei.com> hulk inclusion category: feature bugzilla: 48159 CVE: N/A We can use the checkpoint and restore in userspace(criu) method to dump and restore tasks when updating the kernel. Currently, criu needs dump all memory data of tasks to files. When the memory size is very large(larger than 1G), the cost time of the dumping data will be very long(more than 1 min). By pin the memory data of tasks and collect the corresponding physical pages mapping info in checkpoint process, we can remap the physical pages to restore tasks after upgrading the kernel. This pin memory method can restore the task data within one second. The pin memory area info is saved in the reserved memblock, which can keep usable in the kernel update process. The pin memory driver provides the following ioctl command for criu: 1) SET_PIN_MEM_AREA: Set pin memory area, which can be remap to the restore task. 2) CLEAR_PIN_MEM_AREA: Clear the pin memory area info, which enable user reset the pin data. 3) REMAP_PIN_MEM_AREA: Remap the pages of the pin memory to the restore task.

[PATCH OLK-5.10 v2 1/2] arm64: smp: Add support for cpu park
by sangyan＠huawei.com 26 Feb '21

26 Feb '21

From: Sang Yan <sangyan(a)huawei.com> hulk inclusion category: feature bugzilla: 48159 CVE: N/A Introducing a feature of CPU PARK in order to save time of cpus down and up during kexec, which may cost 250ms of per cpu's down and 30ms of up. As a result, for 128 cores, it costs more than 30 seconds to down and up cpus during kexec. Think about 256 cores and more. CPU PARK is a state that cpu power-on and staying in spin loop, polling for exit chances, such as writing exit address. Reserving a block of memory, to fill with cpu park text section, exit address and park-magic-flag of each cpu. In implementation, reserved one page for one cpu core. Cpus going to park state instead of down in machine_shutdown(). Cpus going out of park state in smp_init instead of brought up.

From: Sang Yan <sangyan(a)huawei.com> hulk inclusion category: feature bugzilla: 48159 CVE: N/A Introducing a feature of CPU PARK in order to save time of cpus down and up during kexec, which may cost 250ms of per cpu's down and 30ms of up. As a result, for 128 cores, it costs more than 30 seconds to down and up cpus during kexec. Think about 256 cores and more. CPU PARK is a state that cpu power-on and staying in spin loop, polling for exit chances, such as writing exit address. Reserving a block of memory, to fill with cpu park text section, exit address and park-magic-flag of each cpu. In implementation, reserved one page for one cpu core. Cpus going to park state instead of down in machine_shutdown(). Cpus going out of park state in smp_init instead of brought up.

[PATCH OLK-5.10 1/3] kexec: Add quick kexec support for kernel
by sangyan＠huawei.com 22 Feb '21

22 Feb '21

From: Sang Yan <sangyan(a)huawei.com> hulk inclusion category: feature bugzilla: 48159 CVE: N/A In normal kexec, relocating kernel may cost 5 ~ 10 seconds, to copy all segments from vmalloced memory to kernel boot memory, because of disabled mmu. We introduce quick kexec to save time of copying memory as above, just like kdump(kexec on crash), by using reserved memory "Quick Kexec". Constructing quick kimage as the same as crash kernel, then simply copy all segments of kimage to reserved memroy. We also add this support in syscall kexec_load using flags of KEXEC_QUICK.

[PATCH openEuler-1.0-LTS 1/2] nbd: Fix memory leak in nbd_add_socket
by Yang Yingliang 07 Feb '21

From: Zheng Bin <zhengbin13(a)huawei.com> stable inclusion from linux-4.19.133 commit 306290bad932950adccfbf99c27b70c105c2c183 -------------------------------- [ Upstream commit 579dd91ab3a5446b148e7f179b6596b270dace46 ] When adding first socket to nbd, if nsock's allocation failed, the data structure member "config->socks" was reallocated, but the data structure member "config->num_connections" was not updated. A memory leak will occur then because the function "nbd_config_put" will free "config->socks" only when "config->num_connections" is not zero.

[PATCH openEuler-1.0-LTS 1/7] futex: Ensure the correct return value from futex_lock_pi()
by Yang Yingliang 04 Feb '21

04 Feb '21

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from linux-4.19.172 commit 72f38fffa4758b878f819f8a47761b3f03443f36 CVE: CVE-2021-3347 -------------------------------- commit 12bb3f7f1b03d5913b3f9d4236a488aa7774dfe9 upstream In case that futex_lock_pi() was aborted by a signal or a timeout and the task returned without acquiring the rtmutex, but is the designated owner of the futex due to a concurrent futex_unlock_pi() fixup_owner() is invoked to establish consistent state. In that case it invokes fixup_pi_state_owner() which in turn tries to acquire the rtmutex again. If that succeeds then it does not propagate this success to fixup_owner() and futex_lock_pi() returns -EINTR or -ETIMEOUT despite having the futex locked. Return success from fixup_pi_state_owner() in all cases where the current task owns the rtmutex and therefore the futex and propagate it correctly through fixup_owner(). Fixup the other callsite which does not expect a positive return value.

[PATCH openEuler-1.0-LTS 1/3] netfilter: clear skb->next in NF_HOOK_LIST()

[PATCH kernel-4.19 1/4] arm64: module: rework special section handling
by Yang Yingliang 04 Feb '21

04 Feb '21

From: Mark Rutland <mark.rutland(a)arm.com> mainline inclusion from mainline-v5.5-rc1 commit bd8b21d3dd661658addc1cd4cc869bab11d28596 category: bugfix bugzilla: 25285 CVE: NA -------------------------------- When we load a module, we have to perform some special work for a couple of named sections. To do this, we iterate over all of the module's sections, and perform work for each section we recognize. To make it easier to handle the unexpected absence of a section, and to make the section-specific logic easer to read, let's factor the section search into a helper. Similar is already done in the core module loader, and other architectures (and ideally we'd unify these in future). If we expect a module to have an ftrace trampoline section, but it doesn't have one, we'll now reject loading the module. When ARM64_MODULE_PLTS is selected, any correctly built module should have one (and this is assumed by arm64's ftrace PLT code) and the absence of such a section implies something has gone wrong at build time. Subsequent patches will make use of the new helper.

[PATCH openEuler-1.0-LTS] scsi: target: Fix XCOPY NAA identifier lookup
by Yang Yingliang 04 Feb '21

04 Feb '21

From: David Disseldorp <ddiss(a)suse.de> stable inclusion from linux-4.19.167 commit fff1180d24e68d697f98642d71444316036a81ff CVE: CVE-2020-28374 -------------------------------- commit 2896c93811e39d63a4d9b63ccf12a8fbc226e5e4 upstream. When attempting to match EXTENDED COPY CSCD descriptors with corresponding se_devices, target_xcopy_locate_se_dev_e4() currently iterates over LIO's global devices list which includes all configured backstores. This change ensures that only initiator-accessible backstores are considered during CSCD descriptor lookup, according to the session's se_node_acl LUN list. To avoid LUN removal race conditions, device pinning is changed from being configfs based to instead using the se_node_acl lun_ref.

Hi, In Linux 5.8, Nick submitted a patch-set to fix some Errors in symbol search when you try to profile JIT compiled application in OpenJDK with perf. The patchset is: 1e4bd2ae4564 perf jit: Fix inaccurate DWARF line table 7d7e503cac31 perf jvmti: Remove redundant jitdump line table entries 0bdf31811be0 perf jvmti: Fix demangling Java symbols 525c821de0a6 perf tests: Add test for the java demangler 959f8ed4c1a8 perf jvmti: Do not report error when missing debug information 953e92402a52 perf jvmti: Fix jitdump for methods without debug info Because making perf work is very useful for performance analysis on JITed Java application, I'd like to support this patchset in openEuler release. The coming 21.03 should be a first target as that release is upgraded with 5.8+ kernel. Probably we can backport this patchset to 20.03 LTS if needed. To introduce the fix to 21.03, the kernel.spec should be changed with some lines to generate the JVMTI shared library. There are some things I am not sure: 1. kernel.spec is in src-openeuler project, do I submit the change by PR or by sending patch directly to the mailing list? 2. Is there rolling release of openEuler like Tumbleweed? Then we can run some tests with the daily ISO before the stable 21.03 And one more question, has version 21.03 created a build project in openEuler OBS?? Is it this one? https://build.openeuler.org/package/show/openEuler:Mainline/kernel Thanks, Erik

Maybe we can put the check into set_vm_checknode(). What do you think? mm/mmap.c if (flags & MAP_CHECKNODE) set_vm_checknode(&vm_flags, flags); Thanks， Bixuan Cui

[PATCH kernel-4.19 1/6] mm: thp: extract split_queue_* into a struct
by Yang Yingliang 18 Jan '21

18 Jan '21

From: Yang Shi <yang.shi(a)linux.alibaba.com> mainline inclusion from mainline-v5.4-rc1 commit 364c1eebe453f06f0c1e837eb155a5725c9cd272 category: bugfix bugzilla: 47240 CVE: NA ------------------------------------------------- Patch series "Make deferred split shrinker memcg aware", v6. Currently THP deferred split shrinker is not memcg aware, this may cause premature OOM with some configuration. For example the below test would run into premature OOM easily: $ cgcreate -g memory:thp $ echo 4G > /sys/fs/cgroup/memory/thp/memory/limit_in_bytes $ cgexec -g memory:thp transhuge-stress 4000 transhuge-stress comes from kernel selftest. It is easy to hit OOM, but there are still a lot THP on the deferred split queue, memcg direct reclaim can't touch them since the deferred split shrinker is not memcg aware. Convert deferred split shrinker memcg aware by introducing per memcg deferred split queue. The THP should be on either per node or per memcg deferred split queue if it belongs to a memcg. When the page is immigrated to the other memcg, it will be immigrated to the target memcg's deferred split queue too. Reuse the second tail page's deferred_list for per memcg list since the same THP can't be on multiple deferred split queues. Make deferred split shrinker not depend on memcg kmem since it is not slab. It doesn't make sense to not shrink THP even though memcg kmem is disabled. With the above change the test demonstrated above doesn't trigger OOM even though with cgroup.memory=nokmem. This patch (of 4): Put split_queue, split_queue_lock and split_queue_len into a struct in order to reduce code duplication when we convert deferred_split to memcg aware in the later patches.

[PATCH openEuler-1.0-LTS] HID: core: Correctly handle ReportSize being zero
by Yang Yingliang 18 Jan '21

18 Jan '21

From: Marc Zyngier <maz(a)kernel.org> stable inclusion from linux-4.19.144 commit abae259fdccc5e41ff302dd80a2b944ce385c970 CVE: CVE-2020-0465 -------------------------------- commit bce1305c0ece3dc549663605e567655dd701752c upstream. It appears that a ReportSize value of zero is legal, even if a bit non-sensical. Most of the HID code seems to handle that gracefully, except when computing the total size in bytes. When fed as input to memset, this leads to some funky outcomes. Detect the corner case and correctly compute the size.

[PATCH kernel-4.19 1/2] ascend: share pool: optimize the big lock for memory processing
by Yang Yingliang 18 Jan '21

18 Jan '21

From: Ding Tianhong <dingtianhong(a)huawei.com> ascend inclusion category: feature bugzilla: NA CVE: NA ------------------------------------------------- The sp_mutex is used to protect all critical path for share pool, it has serious affected the performance of the the memory alloc and release interface when there is a lot of process in the same memory group, it will serious break the scailability of the system, so add a new read semaphore lock to instead of the big lock for allocation and release critical path. The scailability has been greatly improved by this modification. Show the test result: number of process: alloc 4M avg time: Before the patch: 1 32us 3 96us 10 330us after the patch: 1 32us 3 40us 10 60us v2: fix some conflicts and clean some code.

[PATCH openEuler-1.0-LTS] HID: core: Sanitize event code and type when mapping input
by Yang Yingliang 08 Jan '21

From: Marc Zyngier <maz(a)kernel.org> stable inclusion from linux-4.19.144 commit a47b8511d90528c77346597e2012100dfc28cd8c CVE: CVE-2020-0465 -------------------------------- commit 35556bed836f8dc07ac55f69c8d17dce3e7f0e25 upstream. When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap. This event code can come from a variety of sources, including devices masquerading as input devices, only a bit more "programmable". Instead of taking the event code at face value, check that it actually fits the corresponding bitmap, and if it doesn't: - spit out a warning so that we know which device is acting up - NULLify the bitmap pointer so that we catch unexpected uses Code paths that can make use of untrusted inputs can now check that the mapping was indeed correct and bail out if not.

[PATCH openEuler-1.0-LTS] speakup: Reject setting the speakup line discipline outside of speakup
by Yang Yingliang 08 Jan '21

08 Jan '21

From: Samuel Thibault <samuel.thibault(a)ens-lyon.org> mainline inclusion from mainline-v5.10-rc7 commit f0992098cadb4c9c6a00703b66cafe604e178fea category: bugfix bugzilla: NA CVE: CVE-2020-27830 -------------------------------- Speakup exposing a line discipline allows userland to try to use it, while it is deemed to be useless, and thus uselessly exposes potential bugs. One of them is simply that in such a case if the line sends data, spk_ttyio_receive_buf2 is called and crashes since spk_ttyio_synth is NULL. This change restricts the use of the speakup line discipline to speakup drivers, thus avoiding such kind of issues altogether.

[PATCH openEuler-1.0-LTS 1/2] tty: Fix ->pgrp locking in tiocspgrp()
by Yang Yingliang 08 Jan '21

08 Jan '21

From: Jann Horn <jannh(a)google.com> mainline inclusion from mainline-v5.10-rc7 commit 54ffccbf053b5b6ca4f6e45094b942fab92a25fc category: bugfix bugzilla: NA CVE: CVE-2020-29661 -------------------------------- tiocspgrp() takes two tty_struct pointers: One to the tty that userspace passed to ioctl() (`tty`) and one to the TTY being changed (`real_tty`). These pointers are different when ioctl() is called with a master fd. To properly lock real_tty->pgrp, we must take real_tty->ctrl_lock. This bug makes it possible for racing ioctl(TIOCSPGRP, ...) calls on both sides of a PTY pair to corrupt the refcount of `struct pid`, leading to use-after-free errors.

[PATCH openEuler-1.0-LTS] ALSA: rawmidi: Fix racy buffer resize under concurrent accesses
by Yang Yingliang 08 Jan '21

08 Jan '21

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from linux-4.19.124 commit a507658fdb2ad8ca282b0eb42f2a40b805deb1e6 CVE: CVE-2020-27786 -------------------------------- commit c1f6e3c818dd734c30f6a7eeebf232ba2cf3181d upstream. The rawmidi core allows user to resize the runtime buffer via ioctl, and this may lead to UAF when performed during concurrent reads or writes: the read/write functions unlock the runtime lock temporarily during copying form/to user-space, and that's the race window. This patch fixes the hole by introducing a reference counter for the runtime buffer read/write access and returns -EBUSY error when the resize is performed concurrently against read/write. Note that the ref count field is a simple integer instead of refcount_t here, since the all contexts accessing the buffer is basically protected with a spinlock, hence we need no expensive atomic ops. Also, note that this busy check is needed only against read / write functions, and not in receive/transmit callbacks; the race can happen only at the spinlock hole mentioned in the above, while the whole function is protected for receive / transmit callbacks.
