git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timers and timekeeping updates from Thomas Gleixner: - Improve the VDSO build time checks to cover all dynamic relocations VDSO does not allow dynamic relocations, but the build time check is incomplete and fragile. It's based on architectures specifying the relocation types to search for and does not handle R_*_NONE relocation entries correctly. R_*_NONE relocations are injected by some GNU ld variants if they fail to determine the exact .rel[a]/dyn_size to cover trailing zeros. R_*_NONE relocations must be ignored by dynamic loaders, so they should be ignored in the build time check too. Remove the architecture specific relocation types to check for and validate strictly that no other relocations than R_*_NONE end up in the VSDO .so file. - Prefer signal delivery to the current thread for CLOCK_PROCESS_CPUTIME_ID based posix-timers Such timers prefer to deliver the signal to the main thread of a process even if the context in which the timer expires is the current task. This has the downside that it might wake up an idle thread. As there is no requirement or guarantee that the signal has to be delivered to the main thread, avoid this by preferring the current task if it is part of the thread group which shares sighand. This not only avoids waking idle threads, it also distributes the signal delivery in case of multiple timers firing in the context of different threads close to each other better. - Align the tick period properly (again) For a long time the tick was starting at CLOCK_MONOTONIC zero, which allowed users space applications to either align with the tick or to place a periodic computation so that it does not interfere with the tick. The alignement of the tick period was more by chance than by intention as the tick is set up before a high resolution clocksource is installed, i.e. timekeeping is still tick based and the tick period advances from there. The early enablement of sched_clock() broke this alignement as the time accumulated by sched_clock() is taken into account when timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is not longer a multiple of tick periods, which breaks applications which relied on that behaviour. Cure this by aligning the tick starting point to the next multiple of tick periods, i.e 1000ms/CONFIG_HZ. - A set of NOHZ fixes and enhancements: * Cure the concurrent writer race for idle and IO sleeptime statistics The statitic values which are exposed via /proc/stat are updated from the CPU local idle exit and remotely by cpufreq, but that happens without any form of serialization. As a consequence sleeptimes can be accounted twice or worse. Prevent this by restricting the accumulation writeback to the CPU local idle exit and let the remote access compute the accumulated value. * Protect idle/iowait sleep time with a sequence count Reading idle/iowait sleep time, e.g. from /proc/stat, can race with idle exit updates. As a consequence the readout may result in random and potentially going backwards values. Protect this by a sequence count, which fixes the idle time statistics issue, but cannot fix the iowait time problem because iowait time accounting races with remote wake ups decrementing the remote runqueues nr_iowait counter. The latter is impossible to fix, so the only way to deal with that is to document it properly and to remove the assertion in the selftest which triggers occasionally due to that. * Restructure struct tick_sched for better cache layout * Some small cleanups and a better cache layout for struct tick_sched - Implement the missing timer_wait_running() callback for POSIX CPU timers For unknown reason the introduction of the timer_wait_running() callback missed to fixup posix CPU timers, which went unnoticed for almost four years. While initially only targeted to prevent livelocks between a timer deletion and the timer expiry function on PREEMPT_RT enabled kernels, it turned out that fixing this for mainline is not as trivial as just implementing a stub similar to the hrtimer/timer callbacks. The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled systems there is a livelock issue independent of RT. CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU timers out from hard interrupt context to task work, which is handled before returning to user space or to a VM. The expiry mechanism moves the expired timers to a stack local list head with sighand lock held. Once sighand is dropped the task can be preempted and a task which wants to delete a timer will spin-wait until the expiry task is scheduled back in. In the worst case this will end up in a livelock when the preempting task and the expiry task are pinned on the same CPU. The timer wheel has a timer_wait_running() mechanism for RT, which uses a per CPU timer-base expiry lock which is held by the expiry code and the task waiting for the timer function to complete blocks on that lock. This does not work in the same way for posix CPU timers as there is no timer base and expiry for process wide timers can run on any task belonging to that process, but the concept of waiting on an expiry lock can be used too in a slightly different way. Add a per task mutex to struct posix_cputimers_work, let the expiry task hold it accross the expiry function and let the deleting task which waits for the expiry to complete block on the mutex. In the non-contended case this results in an extra mutex_lock()/unlock() pair on both sides. This avoids spin-waiting on a task which is scheduled out, prevents the livelock and cures the problem for RT and !RT systems * tag 'timers-core-2023-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: posix-cpu-timers: Implement the missing timer_wait_running callback selftests/proc: Assert clock_gettime(CLOCK_BOOTTIME) VS /proc/uptime monotonicity selftests/proc: Remove idle time monotonicity assertions MAINTAINERS: Remove stale email address timers/nohz: Remove middle-function __tick_nohz_idle_stop_tick() timers/nohz: Add a comment about broken iowait counter update race timers/nohz: Protect idle/iowait sleep time under seqcount timers/nohz: Only ever update sleeptime from idle exit timers/nohz: Restructure and reshuffle struct tick_sched tick/common: Align tick period with the HZ tick. selftests/timers/posix_timers: Test delivery of signals across threads posix-timers: Prefer delivery of signals to the current thread vdso: Improve cmd_vdso_check to check all dynamic relocations

2023-04-24MIPS: Don't clear _PAGE_SPECIAL in _PAGE_CHG_MASKHenry Willard1-1/+2
In the special case where p = mmap(NULL, ALLOC_SIZE, PROT_READ, MAP_PRIVATE | MAP_ANONYMOUS | MAP_POPULATE, -1, 0); is followed by rc = mprotect(p, ALLOC_SIZE, PROT_NONE); the _PAGE_SPECIAL bit in the page tables will be cleared by mistake and the later unmapped operations will incorrectly modify the struct page for the the zero page. This sequence occurs in the madvise05 test of the Linux Test Project suite of tests. This was discovered while testing an older version of the kernel (5.4.17) on a MIPS device. Unfortunately, support for this device is not available in newer kernels, so I can't test this with the latest Linux kernel code. It looks like the problem exists in newer kernels, but I can't verify it. Except for the LTP test, this sequence of calls is probably not common. Passing it along in the hope it will be useful to someone. Signed-off-by: Henry Willard <[email protected]> Signed-off-by: Thomas Bogendoerfer <[email protected]>
2023-04-22MIPS: Sink body of check_bugs_early() into its only call siteNathan Chancellor2-7/+2
If check_bugs_early() is not inlined, which a compiler is free to do after commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"), modpost would warn that check_bugs_early(), a non-init function, refers to check_bugs64_early(), which is marked __init. This would not result in any run time issues, as check_bugs_early() is only called from setup_arch(), which is marked __init. To avoid this potential warning, just sink the body of check_bugs_early() into its single call site in setup_arch().

2023-04-22MIPS: Mark check_bugs() as __initNathan Chancellor1-1/+1
After commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"), a compiler may choose not to inline a function marked with just 'inline'. If check_bugs() is not inlined into start_kernel(), which occurs when building with clang after commit 9ea7e6b62c2b ("init: Mark [arch_call_]rest_init() __noreturn"), modpost complains with: WARNING: modpost: vmlinux.o: section mismatch in reference: check_bugs (section: .text) -> check_bugs32 (section: .init.text) check_bugs() is only called from start_kernel(), which itself is marked __init, so there would not be any issues at run time. Make it obvious to modpost that this call chain is safe by marking check_bugs() as __init, which fixes the warning.

2023-04-05mips: fix comment about pgtable_init()Mike Rapoport (IBM)1-1/+1
Patch series "mm: move core MM initialization to mm/mm_init.c", v2. This set moves most of the core MM initialization to mm/mm_init.c. This largely includes free_area_init() and its helpers, functions used at boot time, mm_init() from init/main.c and some of the functions it calls. Aside from gaining some more space before mm/page_alloc.c hits 10k lines, this makes mm/page_alloc.c to be mostly about buddy allocator and moves the init code out of the way, which IMO improves maintainability. Besides, this allows to move a couple of declarations out of include/linux and make them private to mm/. And as an added bonus there a slight decrease in vmlinux size. For tinyconfig and defconfig on x86 I've got tinyconfig: text data bss dec hex filename 853206 289376 1200128 2342710 23bf36 a/vmlinux 853198 289344 1200128 2342670 23bf0e b/vmlinux defconfig: text data bss dec hex filename 26152959 9730634 2170884 38054477 244aa4d a/vmlinux 26152945 9730602 2170884 38054431 244aa1f b/vmlinux This patch (of 14): Comment about fixrange_init() says that its called from pgtable_init() while the actual caller is pagetabe_init().

In a future patch HAS_IOPORT=n will disable compilation of the I/O accessor functions inb()/outb() and friends on architectures which can not meaningfully support legacy I/O spaces such as s390. The following architectures do not select HAS_IOPORT: * ARC * C-SKY * Hexagon * Nios II * OpenRISC * s390 * User-Mode Linux * Xtensa All other architectures select HAS_IOPORT at least conditionally.

In commit 6e30a66433af ("driver core: class: remove struct module owner out of struct class"), the module owner pointer was removed from struct class, but this was missed for the mips vpe-cmp code due to lack of build testing (and it being burried under a very unused config settings.) Fix this up by removing the module pointer to resolve the build error. Note, there are other problems with the driver model usage in this file (static struct device usage, empty device release function, etc.), so it probably could use some good cleaning up, but odds are this driver really isn't used so hopefully it will just be removed entirely someday soon as part of the general "remove unused arches" cleanup that is slowly happening.
