[PATCH kernel-4.19 35/57] mm: fix race by making init_zero_pfn() early_initcall
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Ilya Lipnitskiy <ilya.lipnitskiy(a)gmail.com> commit e720e7d0e983bf05de80b231bccc39f1487f0f16 upstream. There are code paths that rely on zero_pfn to be fully initialized before core_initcall. For example, wq_sysfs_init() is a core_initcall function that eventually results in a call to kernel_execve, which causes a page fault with a subsequent mmput. If zero_pfn is not initialized by then it may not get cleaned up properly and result in an error: BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:1 Here is an analysis of the race as seen on a MIPS device. On this particular MT7621 device (Ubiquiti ER-X), zero_pfn is PFN 0 until initialized, at which point it becomes PFN 5120: 1. wq_sysfs_init calls into kobject_uevent_env at core_initcall: kobject_uevent_env+0x7e4/0x7ec kset_register+0x68/0x88 bus_register+0xdc/0x34c subsys_virtual_register+0x34/0x78 wq_sysfs_init+0x1c/0x4c do_one_initcall+0x50/0x1a8 kernel_init_freeable+0x230/0x2c8 kernel_init+0x10/0x100 ret_from_kernel_thread+0x14/0x1c 2. kobject_uevent_env() calls call_usermodehelper_exec() which executes kernel_execve asynchronously. 3. Memory allocations in kernel_execve cause a page fault, bumping the MM reference counter: add_mm_counter_fast+0xb4/0xc0 handle_mm_fault+0x6e4/0xea0 __get_user_pages.part.78+0x190/0x37c __get_user_pages_remote+0x128/0x360 get_arg_page+0x34/0xa0 copy_string_kernel+0x194/0x2a4 kernel_execve+0x11c/0x298 call_usermodehelper_exec_async+0x114/0x194 4. In case zero_pfn has not been initialized yet, zap_pte_range does not decrement the MM_ANONPAGES RSS counter and the BUG message is triggered shortly afterwards when __mmdrop checks the ref counters: __mmdrop+0x98/0x1d0 free_bprm+0x44/0x118 kernel_execve+0x160/0x1d8 call_usermodehelper_exec_async+0x114/0x194 ret_from_kernel_thread+0x14/0x1c To avoid races such as described above, initialize init_zero_pfn at early_initcall level. Depending on the architecture, ZERO_PAGE is either constant or gets initialized even earlier, at paging_init, so there is no issue with initializing zero_pfn earlier.

[PATCH kernel-4.19 34/57] tracing: Fix stack trace event size
by Yang Yingliang 15 Apr '21

15 Apr '21

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> commit 9deb193af69d3fd6dd8e47f292b67c805a787010 upstream. Commit cbc3b92ce037 fixed an issue to modify the macros of the stack trace event so that user space could parse it properly. Originally the stack trace format to user space showed that the called stack was a dynamic array. But it is not actually a dynamic array, in the way that other dynamic event arrays worked, and this broke user space parsing for it. The update was to make the array look to have 8 entries in it. Helper functions were added to make it parse it correctly, as the stack was dynamic, but was determined by the size of the event stored. Although this fixed user space on how it read the event, it changed the internal structure used for the stack trace event. It changed the array size from [0] to [8] (added 8 entries). This increased the size of the stack trace event by 8 words. The size reserved on the ring buffer was the size of the stack trace event plus the number of stack entries found in the stack trace. That commit caused the amount to be 8 more than what was needed because it did not expect the caller field to have any size. This produced 8 entries of garbage (and reading random data) from the stack trace event: <idle>-0 [002] d... 1976396.837549: <stack trace> => trace_event_raw_event_sched_switch => __traceiter_sched_switch => __schedule => schedule_idle => do_idle => cpu_startup_entry => secondary_startup_64_no_verify => 0xc8c5e150ffff93de => 0xffff93de => 0 => 0 => 0xc8c5e17800000000 => 0x1f30affff93de => 0x00000004 => 0x200000000 Instead, subtract the size of the caller field from the size of the event to make sure that only the amount needed to store the stack trace is reserved.

[PATCH kernel-4.19 32/57] PM: runtime: Fix race getting/putting suppliers at probe
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Adrian Hunter <adrian.hunter(a)intel.com> commit 9dfacc54a8661bc8be6e08cffee59596ec59f263 upstream. pm_runtime_put_suppliers() must not decrement rpm_active unless the consumer is suspended. That is because, otherwise, it could suspend suppliers for an active consumer. That can happen as follows: static int driver_probe_device(struct device_driver *drv, struct device *dev) { int ret = 0; if (!device_is_registered(dev)) return -ENODEV; dev->can_match = true; pr_debug("bus: '%s': %s: matched device %s with driver %s\n", drv->bus->name, __func__, dev_name(dev), drv->name); pm_runtime_get_suppliers(dev); if (dev->parent) pm_runtime_get_sync(dev->parent); At this point, dev can runtime suspend so rpm_put_suppliers() can run, rpm_active becomes 1 (the lowest value). pm_runtime_barrier(dev); if (initcall_debug) ret = really_probe_debug(dev, drv); else ret = really_probe(dev, drv); Probe callback can have runtime resumed dev, and then runtime put so dev is awaiting autosuspend, but rpm_active is 2. pm_request_idle(dev); if (dev->parent) pm_runtime_put(dev->parent); pm_runtime_put_suppliers(dev); Now pm_runtime_put_suppliers() will put the supplier i.e. rpm_active 2 -> 1, but consumer can still be active. return ret; } Fix by checking the runtime status. For any status other than RPM_SUSPENDED, rpm_active can be considered to be "owned" by rpm_[get/put]_suppliers() and pm_runtime_put_suppliers() need do nothing.

[PATCH kernel-4.19 31/57] ALSA: hda/realtek: call alc_update_headset_mode() in hp_automute_hook
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Hui Wang <hui.wang(a)canonical.com> commit e54f30befa7990b897189b44a56c1138c6bfdbb5 upstream. We found the alc_update_headset_mode() is not called on some machines when unplugging the headset, as a result, the mode of the ALC_HEADSET_MODE_UNPLUGGED can't be set, then the current_headset_type is not cleared, if users plug a differnt type of headset next time, the determine_headset_type() will not be called and the audio jack is set to the headset type of previous time. On the Dell machines which connect the dmic to the PCH, if we open the gnome-sound-setting and unplug the headset, this issue will happen. Those machines disable the auto-mute by ucm and has no internal mic in the input source, so the update_headset_mode() will not be called by cap_sync_hook or automute_hook when unplugging, and because the gnome-sound-setting is opened, the codec will not enter the runtime_suspend state, so the update_headset_mode() will not be called by alc_resume when unplugging. In this case the hp_automute_hook is called when unplugging, so add update_headset_mode() calling to this function.

[PATCH kernel-4.19 30/57] ALSA: hda/realtek: fix a determine_headset_type issue for a Dell AIO
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Hui Wang <hui.wang(a)canonical.com> commit febf22565549ea7111e7d45e8f2d64373cc66b11 upstream. We found a recording issue on a Dell AIO, users plug a headset-mic and select headset-mic from UI, but can't record any sound from headset-mic. The root cause is the determine_headset_type() returns a wrong type, e.g. users plug a ctia type headset, but that function returns omtp type. On this machine, the internal mic is not connected to the codec, the "Input Source" is headset mic by default. And when users plug a headset, the determine_headset_type() will be called immediately, the codec on this AIO is alc274, the delay time for this codec in the determine_headset_type() is only 80ms, the delay is too short to correctly determine the headset type, the fail rate is nearly 99% when users plug the headset with the normal speed. Other codecs set several hundred ms delay time, so here I change the delay time to 850ms for alc2x4 series, after this change, the fail rate is zero unless users plug the headset slowly on purpose.

[PATCH kernel-4.19 28/57] bpf: Remove MTU check in __bpf_skb_max_len
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Jesper Dangaard Brouer <brouer(a)redhat.com> commit 6306c1189e77a513bf02720450bb43bd4ba5d8ae upstream. Multiple BPF-helpers that can manipulate/increase the size of the SKB uses __bpf_skb_max_len() as the max-length. This function limit size against the current net_device MTU (skb->dev->mtu). When a BPF-prog grow the packet size, then it should not be limited to the MTU. The MTU is a transmit limitation, and software receiving this packet should be allowed to increase the size. Further more, current MTU check in __bpf_skb_max_len uses the MTU from ingress/current net_device, which in case of redirects uses the wrong net_device. This patch keeps a sanity max limit of SKB_MAX_ALLOC (16KiB). The real limit is elsewhere in the system. Jesper's testing[1] showed it was not possible to exceed 8KiB when expanding the SKB size via BPF-helper. The limiting factor is the define KMALLOC_MAX_CACHE_SIZE which is 8192 for SLUB-allocator (CONFIG_SLUB) in-case PAGE_SIZE is 4096. This define is in-effect due to this being called from softirq context see code __gfp_pfmemalloc_flags() and __do_kmalloc_node(). Jakub's testing showed that frames above 16KiB can cause NICs to reset (but not crash). Keep this sanity limit at this level as memory layer can differ based on kernel config.

[PATCH kernel-4.19 01/74] net: fec: ptp: avoid register access when ipg clock is disabled
by Yang Yingliang 12 Apr '21

12 Apr '21

From: Heiko Thiery <heiko.thiery(a)gmail.com> [ Upstream commit 6a4d7234ae9a3bb31181f348ade9bbdb55aeb5c5 ] When accessing the timecounter register on an i.MX8MQ the kernel hangs. This is only the case when the interface is down. This can be reproduced by reading with 'phc_ctrl eth0 get'. Like described in the change in 91c0d987a9788dcc5fe26baafd73bf9242b68900 the igp clock is disabled when the interface is down and leads to a system hang. So we check if the ptp clock status before reading the timecounter register.

openEuler 20.03 合入兆芯补丁冲突适配咨询
by chengjian (D) 07 Apr '21

07 Apr '21

# 1 问题背景 ------- openEuler 20.03 LTS 使用 kernel-4.19 作为开发分支进行补丁适配开发。 zhaoxin 的补丁基于 kernel-4.19 开发，然后我在适配 openEuler-2.0-LTS(20.03) 的时候遇到了一些冲突和编译错误。冲突都比较简单，我已经解决了。后续可以发出来供大家 review。但是编译错误需要大家一起看下。 # 2 问题描述 ------- openEuler apply 兆芯补丁遇到如下编译错误： # 3 问题分析 ------- 导致编译错误的补丁： [PATCH kernel-4.19 v3] xhci: Show Zhaoxin XHCI root hub speed correctly 导致编译错误的原因是：社区的如下补丁，kernel-4.19 合入了，但是 openEuler-1.0-LTS 分支未合入 git log -p kernel-4.19 4e0f891374d8 这些补丁来自于一组 patchset，5.6-rc3 合入 linux mainline xhci: Fix memory leak when caching protocol extended capability PSI tables - take 2 https://patchwork.kernel.org/project/linux-usb/cover/20200210134553.9144-1-… 其中最关键的补丁是 xhci: Fix memory leak when caching protocol extended capability PSI tables - take 2 # 4 需决策内容 ------- 目前有如下 2 个解决方案，大家讨论下看看哪个更好一些。 1. 依赖补丁是一组 bugfix，已经合入 kernel-4.19，补丁直接合入 openEuler 20.03 缺点：需要检视依赖补丁的影响。以及是否还有其他依赖补丁。补丁我已经适配好了，如果选择这个方案，我发出来大家 review下。另外社区是一组 patchset 4个补丁先后都合入了 linux 4.19 stable。20.03 是这4个补丁都合入，还是只需要单点合入依赖的那一个补丁。看起来这个四个补丁之间没有相互依赖关系，都是单独的 bugfix。 2. 了解到兆芯不带依赖补丁，也有一组 patch，是否针对 openEuler 20.03 合入这组补丁。缺点：维护工作量大，需要同时维护两个分支，两组补丁。
