[PATCH Resend] cpufreq: Set cpufreq_cpu_data to NULL before putting kobject

by Viresh Kumar

In __cpufreq_remove_dev_finish(), per-cpu 'cpufreq_cpu_data' needs to be cleared before calling kobject_put(&policy->kobj) *and* under the lock. Otherwise if someone else calls cpufreq_cpu_get() in parallel with it, they can obtain a non-NULL policy from it *after* kobject_put(&policy->kobj) was executed. Consider this case: Thread A Thread B cpufreq_cpu_get() read_lock_irqsave() read-per-cpu cpufreq_cpu_data per_cpu(&cpufreq_cpu_data, cpu) = NULL kobject_put(&policy->kobj); kobject_get(&policy->kobj); And this will result in below Warnings: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 4 at include/linux/kref.h:47 kobject_get+0x41/0x50() Modules linked in: acpi_cpufreq(+) nfsd auth_rpcgss nfs_acl lockd grace sunrpc xfs libcrc32c sd_mod ixgbe igb mdio ahci hwmon ...

But the race happens when another thread puts the kobject first and updates cpufreq_cpu_data before or later. And so the first thread gets a valid policy structure and before it does kobject_get() on it, the second one has already done kobject_put(). Fix this by setting cpufreq_cpu_data to NULL before putting the kobject and that too under locks.

[PATCH v3 0/9] Start deprecating _OSI on new architectures

by al.stone＠linaro.org

From: Al Stone <al.stone(a)linaro.org> The use of the ACPI _OSI method in Linux has a long and sordid history. Instead of perpetuating past complications on new architectures, the consensus amongst those writing the ACPI specification and those using it seems to be to ultimately deprecate the use of _OSI. A change request has been submitted (but not yet decided upon) to modify the ACPI spec accordingly. In the meantime, these patches rearrange the implementation of _OSI so that it can be deprecated, or ultimately removed completely, on at least arm64 platforms. This is done by separating out the _OSI implementation and moving it into a new file. For x86 and ia64, there is no change in functionality. But, this allows us to provide a separate implementation of _OSI for arm64 that generates a warning that it has been deprecated, and always returns false; i.e., that the capability being queried for, whether OS name or functionality, is not supported. Patches 0005 through 0008 provide these changes; the first four patches are solely cleanup to the file drivers/acpi/osl.c made so that checkpatch will not complain. The final patch changes the default value for the _OS_ method for arm64 only. Since there is no need to pretend to be older versions of Windows, or any other OS at all, the _OS_ method will return "Linux" on arm64. One can still use the acpi_os_name kernel parameter if there is a need to use some other value. The first seven patches do not depend on arm64 support for ACPI and could be used independently. The last two patches make much more sense when used in conjunction with Hanjun's patches for ACPI 5.1 on arm64 [0]. In fact, patch 0008 cannot be applied without [0]. These have been through some simple testing on two different x86 laptops, and all seems well (Lenovo t440s and t430s ThinkPads). The arm64 code has been tested on an AMD Seattle system. Unfortunately, for ia64, all I could do was cross-compile the code; I have no access to hardware to test on. NB: the first four patches are solely cleanup to drivers/acpi/osl.c based on the results from checkpatch and can be treated independently. However, the remainder of the patch set assumes this cleanup has been done. There are some checkpatch warnings still remaining in osl.c -- specifically about use of volatiles and one line of 81 characters -- that these patches intentionally do not correct as they do not appear to need correcting. Changes in v3: -- add in cleanup to osl.c based on checkpatch output -- put arch-specific _OSI implementation in the correct place (arch/*) -- modify CONFIG item names and make them so they are not user selectable -- get rid of the BLACKLIST config item; it wasn't really needed. Changes in v2: -- significant simplification based on Rafael's comments -- ACPI spec change request has now been submitted [0] https://lkml.org/lkml/2015/2/2/261 Al Stone (9): ACPI: fix all errors reported by cleanpatch.pl in osl.c ACPI: clear up warnings on use of printk reported by checkpatch.pl ACPI: clean up checkpatch warnings for various bits of syntax ACPI: clean up checkpatch warnings for items with possible semantic value ACPI: move acpi_os_handler() so it can be made arch-dependent later ACPI: move _OSI support functions to allow arch-dependent implementation ACPI: enable arch-specific compilation for _OSI and the blacklist ACPI: arm64: use an arch-specific ACPI _OSI method and ACPI blacklist ACPI: arm64: use "Linux" as ACPI_OS_NAME for _OS on arm64 arch/arm64/Kconfig | 6 + arch/arm64/kernel/Makefile | 2 +- arch/arm64/kernel/acpi-blacklist.c | 20 ++ arch/arm64/kernel/acpi-osi.c | 25 +++ drivers/acpi/Kconfig | 3 + drivers/acpi/Makefile | 5 + drivers/acpi/osi.c | 245 +++++++++++++++++++++++ drivers/acpi/osl.c | 387 ++++++++----------------------------- include/acpi/acconfig.h | 2 + include/acpi/platform/aclinux.h | 4 + include/linux/acpi.h | 14 +- 11 files changed, 406 insertions(+), 307 deletions(-) create mode 100644 arch/arm64/kernel/acpi-blacklist.c create mode 100644 arch/arm64/kernel/acpi-osi.c create mode 100644 drivers/acpi/osi.c -- 2.1.0

[RFC PATCH] sched_clock: Avoid tearing during read from NMI

by Daniel Thompson

Currently it is possible for an NMI (or FIQ on ARM) to come in and read sched_clock() whilst update_sched_clock() has half updated the state. This results in a bad time value being observed. This patch fixes that problem in a similar manner to Thomas Gleixner's 4396e058c52e("timekeeping: Provide fast and NMI safe access to CLOCK_MONOTONIC"). Note that ripping out the seqcount lock from sched_clock_register() and replacing it with a large comment is not nearly as bad as it looks! The locking here is actually pretty useless since most of the variables modified within the write lock are not covered by the read lock. As a result a big comment and the sequence bump implicit in the call to update_epoch() should work pretty much the same. Suggested-by: Stephen Boyd <sboyd(a)codeaurora.org> Signed-off-by: Daniel Thompson <daniel.thompson(a)linaro.org> --- Notes: This patch has only had fairly light testing at this point. However it survives basic tests. In particular I am running perf from FIQ/NMI and have instrumented it with some monotonicity tests none of which have reported any problem. kernel/time/sched_clock.c | 63 +++++++++++++++++++++++++++++++++++++---------- 1 file changed, 50 insertions(+), 13 deletions(-) diff --git a/kernel/time/sched_clock.c b/kernel/time/sched_clock.c index 01d2d15aa662..485d5070259c 100644 --- a/kernel/time/sched_clock.c +++ b/kernel/time/sched_clock.c @@ -27,6 +27,10 @@ struct clock_data { u32 mult; u32 shift; bool suspended; + + /* Used only temporarily whilst we are updating the primary copy */ + u64 old_epoch_ns; + u64 old_epoch_cyc; }; static struct hrtimer sched_clock_timer; @@ -67,9 +71,14 @@ unsigned long long notrace sched_clock(void) return cd.epoch_ns; do { - seq = raw_read_seqcount_begin(&cd.seq); - epoch_cyc = cd.epoch_cyc; - epoch_ns = cd.epoch_ns; + seq = raw_read_seqcount(&cd.seq); + if (likely(0 == (seq & 1))) { + epoch_cyc = cd.epoch_cyc; + epoch_ns = cd.epoch_ns; + } else { + epoch_cyc = cd.old_epoch_cyc; + epoch_ns = cd.old_epoch_ns; + } } while (read_seqcount_retry(&cd.seq, seq)); cyc = read_sched_clock(); @@ -78,6 +87,35 @@ unsigned long long notrace sched_clock(void) } /* + * Update the epoch without allowing sched_clock to observe + * a mismatched epoch pair even if called from NMI. + * + * We do this by maintaining and odd/even copy of the epoch data and + * steering sched_clock to one or the other using a sequence counter. + * In order to preserve the (average case) data cache profile of + * sched_clock the system reverts back to the even copy as soon as + * possible; the odd copy is used *only* during an update. + * + * The caller is responsible for avoiding simultaneous updates. + */ +static void notrace update_epoch(u64 cyc, u64 ns) +{ + /* Update the backup copy */ + cd.old_epoch_cyc = cd.epoch_cyc; + cd.old_epoch_ns = cd.epoch_ns; + + /* Force readers to use the backup (odd) copy */ + raw_write_seqcount_latch(&cd.seq); + + /* Update the primary copy */ + cd.epoch_cyc = cyc; + cd.epoch_ns = ns; + + /* Steer readers back the primary (even) copy */ + raw_write_seqcount_latch(&cd.seq); +} + +/* * Atomically update the sched_clock epoch. */ static void notrace update_sched_clock(void) @@ -91,12 +129,7 @@ static void notrace update_sched_clock(void) cyc_to_ns((cyc - cd.epoch_cyc) & sched_clock_mask, cd.mult, cd.shift); - raw_local_irq_save(flags); - raw_write_seqcount_begin(&cd.seq); - cd.epoch_ns = ns; - cd.epoch_cyc = cyc; - raw_write_seqcount_end(&cd.seq); - raw_local_irq_restore(flags); + update_epoch(cyc, ns); } static enum hrtimer_restart sched_clock_poll(struct hrtimer *hrt) @@ -135,16 +168,20 @@ void __init sched_clock_register(u64 (*read)(void), int bits, ns = cd.epoch_ns + cyc_to_ns((cyc - cd.epoch_cyc) & sched_clock_mask, cd.mult, cd.shift); - raw_write_seqcount_begin(&cd.seq); + /* + * sched_clock will report a bad value if it executes + * concurrently with the following code.

[cpu hot-plug] kernel started with maxcpus argument fordbids to bring more CPUs online

by Lomovtsev, Vadim

Hi all, ?While using maxcpus=n we can limit the number of boot time cpus to n and later we can bring them online (according to Documentation/cpu-hotplug.txt). However current implementation doesn't allow to bring more cpus online than it was specified with maxcpus argument. As far as I can understand the decision of bringing up cpus on is based on cpu_present mask which is set accordingly to maxcpus argument while kernel start up at the smp_prepare_cpus(max_cpus) function (file arch/aarm64/kernel/smp.c). At the same time the cpu_possible mask contains all the cpus visible to kernel (info provided by acpi) - for my system they are all there. Could anyone clarify why it was implemented in that way (e.g. for x86 architecture there is no such limitation; the smp_prepare_cpus(max_cpus) function ignores the max_cpus argument) ? Was it implemented intentionally to prevent some issues/bugs? WBR, Vadim Lomovtsev
