Masami Hiramatsu (Google)	5d3d6f75d5	BACKPORT: hung_task: show the blocker task if the task is hung on mutex ... Patch series "hung_task: Dump the blocking task stacktrace", v4. The hung_task detector is very useful for detecting the lockup. However, since it only dumps the blocked (uninterruptible sleep) processes, it is not enough to identify the root cause of that lockup. For example, if a process holds a mutex and sleep an event in interruptible state long time, the other processes will wait on the mutex in uninterruptible state. In this case, the waiter processes are dumped, but the blocker process is not shown because it is sleep in interruptible state. This adds a feature to dump the blocker task which holds a mutex when detecting a hung task. e.g. INFO: task cat:115 blocked for more than 122 seconds.

We can follow the waiter link but the output will be a bit different compared with mutex case. This patch (of 2): The "hung_task" shows a long-time uninterruptible slept task, but most often, it's blocked on a mutex acquired by another task. Without dumping such a task, investigating the root cause of the hung task problem is very difficult. This introduce task_struct::blocker_mutex to point the mutex lock which this task is waiting for. Since the mutex has "owner" information, we can find the owner task and dump it with hung tasks. Note: the owner can be changed while dumping the owner task, so this is "likely" the owner of the mutex. With this change, the hung task shows blocker task's info like below; INFO: task cat:115 blocked for more than 122 seconds.

Sergio González Collado	b8abcba6e4	Kunit to check the longest symbol length ... commit c104c16073b7fdb3e4eae18f66f4009f6b073d6f upstream. The longest length of a symbol (KSYM_NAME_LEN) was increased to 512 in the reference [1]. This patch adds kunit test suite to check the longest symbol length. These tests verify that the longest symbol length defined is supported. This test can also help other efforts for longer symbol length, like [2]. The test suite defines one symbol with the longest possible length. The first test verify that functions with names of the created symbol, can be called or not. The second test, verify that the symbols are created (or not) in the kernel symbol table.

Carlos Llamas	149dd2acff	lockdep: Fix upper limit for LOCKDEP_*_BITS configs ... [ Upstream commit e638072e61726cae363d48812815197a2a0e097f ] Lockdep has a set of configs used to determine the size of the static arrays that it uses. However, the upper limit that was initially setup for these configs is too high (30 bit shift). This equates to several GiB of static memory for individual symbols. Using such high values leads to linker errors: $ make defconfig $ ./scripts/config -e PROVE_LOCKING --set-val LOCKDEP_BITS 30 $ make olddefconfig all [...] ld: kernel image bigger than KERNEL_IMAGE_SIZE ld: section .bss VMA wraps around address space Adjust the upper limits to the maximum values that avoid these issues. The need for anything more, likely points to a problem elsewhere. Note that LOCKDEP_CHAINS_BITS was intentionally left out as its upper limit had a different symptom and has already been fixed [1].

Thomas Gleixner	7b7a9175c6	timekeeping: Remove CONFIG_DEBUG_TIMEKEEPING ... commit d44d26987bb3df6d76556827097fc9ce17565cb8 upstream. Since 135225a363 timekeeping_cycles_to_ns() handles large offsets which would lead to 64bit multiplication overflows correctly. It's also protected against negative motion of the clocksource unconditionally, which was exclusive to x86 before. timekeeping_advance() handles large offsets already correctly. That means the value of CONFIG_DEBUG_TIMEKEEPING which analyzed these cases is very close to zero. Remove all of it.

This can be used to determine the base address of the section at runtime. Next, it lists (in strict ascending order) offset ranges in that section that cover the symbols of one or more builtin modules. Multiple ranges can apply to a single module, and ranges can be shared between modules. The CONFIG_BUILTIN_MODULE_RANGES option controls whether offset range data is generated for kernel modules that are built into the kernel image. How it works: 1. The modules.builtin file is parsed to obtain a list of built-in module names and their associated object names (the .ko file that the module would be in if it were a loadable module, hereafter referred to as <kmodfile>). This object name can be used to identify objects in the kernel compile because any C or assembler code that ends up into a built-in module will have the option -DKBUILD_MODFILE=<kmodfile> present in its build command, and those can be found in the .<obj>.cmd file in the kernel build tree. If an object is part of multiple modules, they will all be listed in the KBUILD_MODFILE option argument. This allows us to conclusively determine whether an object in the kernel build belong to any modules, and which. 2. The vmlinux.map is parsed next to determine the base address of each top level section so that all addresses into the section can be turned into offsets. This makes it possible to handle sections getting loaded at different addresses at system boot. We also determine an 'anchor' symbol at the beginning of each section to make it possible to calculate the true base address of a section at runtime (i.e. symbol address - symbol offset). We collect start addresses of sections that are included in the top level section. This is used when vmlinux is linked using vmlinux.o, because in that case, we need to look at the vmlinux.o linker map to know what object a symbol is found in. And finally, we process each symbol that is listed in vmlinux.map (or vmlinux.o.map) based on the following structure: vmlinux linked from vmlinux.a: vmlinux.map: <top level section> <included section> -- might be same as top level section) <object> -- built-in association known <symbol> -- belongs to module(s) object belongs to ... vmlinux linked from vmlinux.o: vmlinux.map: <top level section> <included section> -- might be same as top level section) vmlinux.o -- need to use vmlinux.o.map <symbol> -- ignored ... vmlinux.o.map: <section> <object> -- built-in association known <symbol> -- belongs to module(s) object belongs to ... 3. As sections, objects, and symbols are processed, offset ranges are constructed in a straight-forward way: - If the symbol belongs to one or more built-in modules: - If we were working on the same module(s), extend the range to include this object - If we were working on another module(s), close that range, and start the new one - If the symbol does not belong to any built-in modules: - If we were working on a module(s) range, close that range Signed-off-by: Kris Van Hees <kris.van.hees@oracle.com> Reviewed-by: Nick Alcock <nick.alcock@oracle.com> Reviewed-by: Alan Maguire <alan.maguire@oracle.com> Reviewed-by: Steven Rostedt (Google) <rostedt@goodmis.org> Tested-by: Sam James <sam@gentoo.org> Reviewed-by: Sami Tolvanen <samitolvanen@google.com> Tested-by: Sami Tolvanen <samitolvanen@google.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>	2024-09-20 09:21:43 +09:00

GCC 11+ and Clang 14+ default to DWARF 5 when the -g flag is passed. For the same reason, the combination of CONFIG_DEBUG_INFO_BTF and CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT is also likely to require pahole 1.21+ these days.

Use this new mechanism in the watchdog code to do a two stage lockup analysis by taking the snapshot and printing the deltas for the topmost active interrupts on the second trigger. Note: This contains both the interrupt and the watchdog changes as the latter depend on the former obviously. - Avoid summation loops in the /proc/interrupts output and use the global counter when possible - Skip suspended interrupts on CPU hotplug operations to ensure that they are not delivered before the system resumes the device drivers when coming out of suspend. - On CPU hot-unplug interrupts which are affine to the outgoing CPU are migrated to a different CPU in the affinity mask.

Bitao Hu	d7037381d0	watchdog/softlockup: Low-overhead detection of interrupt storm ... The following softlockup is caused by interrupt storm, but it cannot be identified from the call tree. Because the call tree is just a snapshot and doesn't fully capture the behavior of the CPU during the soft lockup. watchdog: BUG: soft lockup - CPU#28 stuck for 23s! [fio:83921] ... Call trace: __do_softirq+0xa0/0x37c __irq_exit_rcu+0x108/0x140 irq_exit+0x14/0x20 __handle_domain_irq+0x84/0xe0 gic_handle_irq+0x80/0x108 el0_irq_naked+0x50/0x58 Therefore, it is necessary to report CPU utilization during the softlockup_threshold period (report once every sample_period, for a total of 5 reportings), like this: watchdog: BUG: soft lockup - CPU#28 stuck for 23s! [fio:83921] CPU#28 Utilization every 4s during lockup: #1: 0% system, 0% softirq, 100% hardirq, 0% idle #2: 0% system, 0% softirq, 100% hardirq, 0% idle #3: 0% system, 0% softirq, 100% hardirq, 0% idle #4: 0% system, 0% softirq, 100% hardirq, 0% idle #5: 0% system, 0% softirq, 100% hardirq, 0% idle ... This is helpful in determining whether an interrupt storm has occurred or in identifying the cause of the softlockup. The criteria for determination are as follows: a. If the hardirq utilization is high, then interrupt storm should be considered and the root cause cannot be determined from the call tree. b. If the softirq utilization is high, then the call might not necessarily point at the root cause. c. If the system utilization is high, then analyzing the root cause from the call tree is possible in most cases. The mechanism requires a considerable amount of global storage space when configured for the maximum number of CPUs. Therefore, adding a SOFTLOCKUP_DETECTOR_INTR_STORM Kconfig knob that defaults to "yes" if the max number of CPUs is <= 128.

Andrii Nakryiko	229087f6f1	bpf, kconfig: Fix DEBUG_INFO_BTF_MODULES Kconfig definition ... Turns out that due to CONFIG_DEBUG_INFO_BTF_MODULES not having an explicitly specified "menu item name" in Kconfig, it's basically impossible to turn it off (see [0]). This patch fixes the issue by defining menu name for CONFIG_DEBUG_INFO_BTF_MODULES, which makes it actually adjustable and independent of CONFIG_DEBUG_INFO_BTF, in the sense that one can have DEBUG_INFO_BTF=y and DEBUG_INFO_BTF_MODULES=n. We still keep it as defaulting to Y, of course.
