+ slub-track-number-of-slabs-irrespective-of-config_slub_debug.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: slub: track number of slabs irrespective of CONFIG_SLUB_DEBUG has been added to the -mm tree. Its filename is slub-track-number-of-slabs-irrespective-of-config_slub_debug.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/slub-track-number-of-slabs-irrespe… and later at http://ozlabs.org/~akpm/mmotm/broken-out/slub-track-number-of-slabs-irrespe… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Shakeel Butt <shakeelb(a)google.com> Subject: slub: track number of slabs irrespective of CONFIG_SLUB_DEBUG For !CONFIG_SLUB_DEBUG, SLUB does not maintain the number of slabs allocated per node for a kmem_cache. Thus, slabs_node() in __kmem_cache_empty(), __kmem_cache_shrink() and __kmem_cache_destroy() will always return 0 for such config. This is wrong and can cause issues for all users of these functions. In fact in [1] Jason has reported a system crash while using SLUB without CONFIG_SLUB_DEBUG. The reason was the usage of slabs_node() by __kmem_cache_empty(). The right solution is to make slabs_node() work even for !CONFIG_SLUB_DEBUG. The commit 0f389ec63077 ("slub: No need for per node slab counters if !SLUB_DEBUG") had put the per node slab counter under CONFIG_SLUB_DEBUG because it was only read through sysfs API and the sysfs API was disabled on !CONFIG_SLUB_DEBUG. However the users of the per node slab counter assumed that it will work in the absence of CONFIG_SLUB_DEBUG. So, make the counter work for !CONFIG_SLUB_DEBUG. Please note that f9e13c0a5a33 ("slab, slub: skip unnecessary kasan_cache_shutdown()") exposed this issue but it is present even before.

[PATCH] MIPS: Always use -march=<arch>, not -<arch> shortcuts

by Paul Burton

The VDSO Makefile filters CFLAGS to select a subset which it uses whilst building the VDSO ELF. One of the flags it allows through is the -march= flag that selects the architecture/ISA to target. Unfortunately in cases where CONFIG_CPU_MIPS32_R{1,2}=y and the toolchain defaults to building for MIPS64, the main MIPS Makefile ends up using the short-form -<arch> flags in cflags-y. This is because the calls to cc-option always fail to use the long-form -march=<arch> flag due to the lack of an -mabi=<abi> flag in KBUILD_CFLAGS at the point where the cc-option function is executed. The resulting GCC invocation is something like: $ mips64-linux-gcc -Werror -march=mips32r2 -c -x c /dev/null -o tmp cc1: error: '-march=mips32r2' is not compatible with the selected ABI These short-form -<arch> flags are dropped by the VDSO Makefile's filtering, and so we attempt to build the VDSO without specifying any architecture. This results in an attempt to build the VDSO using whatever the compiler's default architecture is, regardless of whether that is suitable for the kernel configuration. One encountered build failure resulting from this mismatch is a rejection of the sync instruction if the kernel is configured for a MIPS32 or MIPS64 r1 or r2 target but the toolchain defaults to an older architecture revision such as MIPS1 which did not include the sync instruction: CC arch/mips/vdso/gettimeofday.o /tmp/ccGQKoOj.s: Assembler messages: /tmp/ccGQKoOj.s:273: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:329: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:520: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:714: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1009: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1066: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1114: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1279: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1334: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1374: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1459: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1514: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1814: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:2002: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:2066: Error: opcode not supported on this processor: mips1 (mips1) `sync' make[2]: *** [scripts/Makefile.build:318: arch/mips/vdso/gettimeofday.o] Error 1 make[1]: *** [scripts/Makefile.build:558: arch/mips/vdso] Error 2 make[1]: *** Waiting for unfinished jobs.... This can be reproduced for example by attempting to build pistachio_defconfig using Arnd's GCC 8.1.0 mips64 toolchain from kernel.org: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/… Resolve this problem by using the long-form -march=<arch> in all cases, which makes it through the arch/mips/vdso/Makefile's filtering & is thus consistently used to build both the kernel proper & the VDSO. The use of cc-option to prefer the long-form & fall back to the short-form flags makes no sense since the short-form is just an abbreviation for the also-supported long-form in all GCC versions that we support building with. This means there is no case in which we have to use the short-form -<arch> flags, so we can simply remove them. The manual redefinition of _MIPS_ISA is removed naturally along with the use of the short-form flags that it accompanied, and whilst here we remove the separate assembler ISA selection. I suspect that both of these were only required due to the mips32 vs mips2 mismatch that was introduced by commit 59b3e8e9aac6 ("[MIPS] Makefile crapectomy.") and fixed but not cleaned up by commit 9200c0b2a07c ("[MIPS] Fix Makefile bugs for MIPS32/MIPS64 R1 and R2."). I've marked this for backport as far as v4.4 where the MIPS VDSO was introduced. In earlier kernels there should be no ill effect to using the short-form flags.

[PATCH v2 1/2] iommu/vt-d: add definitions for PFSID

by Jacob Pan

When SRIOV VF device IOTLB is invalidated, we need to provide the PF source ID such that IOMMU hardware can gauge the depth of invalidation queue which is shared among VFs. This is needed when device invalidation throttle (DIT) capability is supported. This patch adds bit definitions for checking and tracking PFSID.

Hi, I think the patch really should not be added to the stable tree. It is not a bug fix. It is a new feature. The original API was more limited and this patch extends it. The same applies to patch "livepatch: Allow to call a custom callback when freeing shadow variables". Regards, Miroslav

[PATCH] mtd: rawnand: mxc: set spare area size register explicitly

by Martin Kaiser

The v21 version of the NAND flash controller contains a Spare Area Size Register (SPAS) at offset 0x10. Its setting defaults to the maximum spare area size of 218 bytes. The size that is set in this register is used by the controller when it calculates the ECC bytes internally in hardware. Usually, this register is updated from settings in the IIM fuses when the system is booting from nand flash. For other boot media, however, the SPAS register remains at the default setting, which may not work for the particular flash chip on the board. The same goes for flash chips whose configuration cannot be set in the IIM fuses (e.g. chips with 2k sector size and 128 bytes spare area size can't be configured in the IIM fuses on imx25 systems). Set the SPAS register explicitly during the preset operation. Derive the register value from mtd->oobsize that was detected during probe by decoding the flash chip's ID bytes. While at it, rename the define for the spare area register's offset to NFC_V21_RSLTSPARE_AREA. The register at offset 0x10 on v1 controllers is different from the register on v21 controllers.

[PATCH] MIPS: implement smp_cond_load_acquire() for Loongson-3

by Huacai Chen

After commit 7f56b58a92aaf2c ("locking/mcs: Use smp_cond_load_acquire() in MCS spin loop") Loongson-3 fails to boot. This is because Loongson-3 has SFB (Store Fill Buffer) and READ_ONCE() may get an old value in a tight loop. So in smp_cond_load_acquire() we need a __smp_mb() after every READ_ONCE(). This patch introduce a Loongson-specific smp_cond_load_acquire(). And it should be backported to as early as linux-4.5, in which release the smp_cond_acquire() is introduced.

[PATCH v4 06/15] mtd: rawnand: qcom: wait for desc completion in all BAM channels

by Abhishek Sahu

The BAM has 3 channels - tx, rx and command. command channel is used for register read/writes, tx channel for data writes and rx channel for data reads. Currently, the driver assumes the transfer completion once it gets all the command descriptors completed. Sometimes, there is race condition between data channel (tx/rx) and command channel completion. In these cases, the data present in buffer is not valid during small window between command descriptor completion and data descriptor completion. This patch generates NAND transfer completion when both (Data and Command) DMA channels have completed all its DMA descriptors. It assigns completion callback in last DMA descriptors of that channel and wait for completion.

[PATCH] printk/nmi: Prevent deadlock when serializing NMI backtraces

by Petr Mladek

The commit 719f6a7040f1bdaf96fcc ("printk: Use the main logbuf in NMI when logbuf_lock is available") tried to detect when logbuf_lock was taken on another CPU. Then it looked safe to wait for the lock even in NMI. It would be safe if other locks were not involved. Ironically the same commit introduced an ABBA deadlock scenario. It added a spin lock into nmi_cpu_backtrace() to serialize logs from different CPUs. The effect is that also the NMI handlers are serialized. As a result, logbuf_lock might be blocked by NMI on another CPU: CPU0 CPU1 CPU2 printk() vprintk_emit() spin_lock(&logbuf_lock) trigger_all_cpu_backtrace() raise() nmi_enter() printk_nmi_enter() if (this_cpu_read(printk_context) & PRINTK_SAFE_CONTEXT_MASK) // false else // looks safe to use printk_deferred() this_cpu_or(printk_context, PRINTK_NMI_DEFERRED_CONTEXT_MASK); nmi_cpu_backtrace() arch_spin_lock(&lock); show_regs() nmi_enter() nmi_cpu_backtrace() arch_spin_lock(&lock); printk() vprintk_func() vprintk_deferred() vprintk_emit() spin_lock(&logbuf_lock) DEADLOCK: between &logbuf_lock from vprintk_emit() and &lock from nmi_cpu_backtrace(). CPU0 CPU1 lock(logbuf_lock) lock(lock) lock(lock) lock(logbuf_lock) I have found this problem when stress testing trigger_all_cpu_backtrace() and the system frozen. Note that lockdep is not able to detect these dependencies because there is no support for NMI context. Let's stay on the safe side and always use printk_safe buffers when logbuf_lock is taken when entering NMI.

[PATCH] scsi: sd: Optimal I/O size should be a multiple of physical block size

It was reported that some devices report an OPTIMAL TRANSFER LENGTH of 0xFFFF blocks. That looks bogus, especially for a device with a 4096-byte physical block size.

[PATCH v3 4/7] vmw_balloon: fix VMCI use when balloon built into kernel

by Nadav Amit

Currently, when all modules, including VMCI and VMware balloon are built into the kernel, the initialization of the balloon happens before the VMCI is probed. As a result, the balloon fails to initialize the VMCI doorbell, which it uses to get asynchronous requests for balloon size changes. The problem can be seen in the logs, in the form of the following message: "vmw_balloon: failed to initialize vmci doorbell" The driver would work correctly but slightly less efficiently, probing for requests periodically. This patch changes the balloon to be initialized using late_initcall() instead of module_init() to address this issue. It does not address a situation in which VMCI is built as a module and the balloon is built into the kernel.

[PATCH v3 3/7] vmw_balloon: VMCI_DOORBELL_SET does not check status

by Nadav Amit

When vmballoon_vmci_init() sets a doorbell using VMCI_DOORBELL_SET, for some reason it does not consider the status and looks at the result. However, the hypervisor does not update the result - it updates the status. This might cause VMCI doorbell not to be enabled, resulting in degraded performance.

[PATCH v3 2/7] vmw_balloon: do not use 2MB without batching

by Nadav Amit

If the hypervisor sets 2MB batching is on, while batching is cleared, the balloon code breaks. In this case the legacy mechanism is used with 2MB page. The VM would report a 2MB page is ballooned, and the hypervisor would only take the first 4KB. While the hypervisor should not report such settings, make the code more robust by not enabling 2MB support without batching. Fixes: 365bd7ef7ec8e ("VMware balloon: Support 2m page ballooning.")
