"KVM: s390: reduce number of IO pins to 1" for stable

by Christian Borntraeger

stable team, Please consider commit 774911290c58 ("KVM: s390: reduce number of IO pins to 1") for stable. This can avoid OOM killer activity on highly fragmented memory even when swap and memory is available. We decided too late that this is stable material, so sorry for not marking it correctly.

Yes, Chris is right. Mapping DMA-buf through the mmap() APIs of an importer is illegal. What we could maybe try to do is to redirect this mmap() API call on the importer to the exporter, but I'm pretty sure that the fs layer wouldn't like that without changes.

[PATCH] omapfb: dss: Fix max fclk divider for omap36xx

by Adam Ford

There appears to be a timing issue where using a divider of 32 breaks the DSS for OMAP36xx despite the TRM stating 32 is a valid number. Through experimentation, it appears that 31 works. This same fix was issued for kernels 4.5+. However, between kernels 4.4 and 4.5, the directory structure was changed when the dss directory was moved inside the omapfb directory. That broke the patch on kernels older than 4.5, because it didn't permit the patch to apply cleanly for 4.4 and older. A similar patch was applied to the 3.16 kernel already, but not to 4.4. Commit 4b911101a5cd ("drm/omap: fix max fclk divider for omap36xx") is on the 3.16 stable branch with notes from Ben about the path change. Since this was applied for 3.16 already, this patch is for kernels 3.17 through 4.4 only.

[PATCH resend v2 1/8] virt: vbox: Fix VBGL_IOCTL_VMMDEV_REQUEST_BIG and _LOG req numbers to match upstream

by Hans de Goede

Until this commit the mainline kernel version (this version) of the vboxguest module contained a bug where it defined VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG using _IOC(_IOC_READ | _IOC_WRITE, 'V', ...) instead of _IO(V, ...) as the out of tree VirtualBox upstream version does. Since the VirtualBox userspace bits are always built against VirtualBox upstream's headers, this means that so far the mainline kernel version of the vboxguest module has been failing these 2 ioctls with -ENOTTY. I guess that VBGL_IOCTL_VMMDEV_REQUEST_BIG is never used causing us to not hit that one and sofar the vboxguest driver has failed to actually log any log messages passed it through VBGL_IOCTL_LOG. This commit changes the VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG defines to match the out of tree VirtualBox upstream vboxguest version, while keeping compatibility with the old wrong request defines so as to not break the kernel ABI in case someone has been using the old request defines.

[PATCH 1/1] usb: cdns3: gadget: own the lock wrongly at the suspend routine

by Peter Chen

When it is device mode with cable connected to host, the call stack is: cdns3_suspend->cdns3_gadget_suspend->cdns3_disconnect_gadget, the cdns3_disconnect_gadget owns lock wrongly at this situation, it causes the system being deadlock after resume due to at cdns3_device_thread_irq_handler, it tries to get the lock, but will never get it. To fix it, we delete the lock operations, and add them at the caller when necessary.

[PATCH v2 1/2 net] bitfield.h: don't compile-time validate _val in FIELD_FIT

by Nick Desaulniers

From: Jakub Kicinski <kuba(a)kernel.org> When ur_load_imm_any() is inlined into jeq_imm(), it's possible for the compiler to deduce a case where _val can only have the value of -1 at compile time. Specifically, /* struct bpf_insn: _s32 imm */ u64 imm = insn->imm; /* sign extend */ if (imm >> 32) { /* non-zero only if insn->imm is negative */ /* inlined from ur_load_imm_any */ u32 __imm = imm >> 32; /* therefore, always 0xffffffff */ if (__builtin_constant_p(__imm) && __imm > 255) compiletime_assert_XXX() This can result in tripping a BUILD_BUG_ON() in __BF_FIELD_CHECK() that checks that a given value is representable in one byte (interpreted as unsigned). FIELD_FIT() should return true or false at runtime for whether a value can fit for not. Don't break the build over a value that's too large for the mask. We'd prefer to keep the inlining and compiler optimizations though we know this case will always return false.

[PATCH] KVM: arm64: Fix definition of PAGE_HYP_DEVICE

by Will Deacon

PAGE_HYP_DEVICE is intended to encode attribute bits for an EL2 stage-1 pte mapping a device. Unfortunately, it includes PROT_DEVICE_nGnRE which encodes attributes for EL1 stage-1 mappings such as UXN and nG, which are RES0 for EL2, and DBM which is meaningless as TCR_EL2.HD is not set. Fix the definition of PAGE_HYP_DEVICE so that it doesn't set RES0 bits at EL2.

[PATCH] arm64: dts: qcom: sc7180: Drop the unused non-MSA SID

by Sibi Sankar

Having a non-MSA (Modem Self-Authentication) SID bypassed breaks modem sandboxing i.e if a transaction were to originate from it, the hardware memory protections units (XPUs) would fail to flag them (any transaction originating from modem are historically termed as an MSA transaction). Drop the unused non-MSA modem SID on SC7180 SoCs and cheza so that SMMU continues to block them.

[PATCH 3/5] module: Do not expose section addresses to non-CAP_SYSLOG

by Kees Cook

The printing of section addresses in /sys/module/*/sections/* was not using the correct credentials to evaluate visibility.

[PATCH v2] drm/vgem: Replace opencoded version of drm_gem_dumb_map_offset()

by Chris Wilson

drm_gem_dumb_map_offset() now exists and does everything vgem_gem_dump_map does and *ought* to do. In particular, vgem_gem_dumb_map() was trying to reject mmapping an imported dmabuf by checking the existence of obj->filp. Unfortunately, we always allocated an obj->filp, even if unused for an imported dmabuf. Instead, the drm_gem_dumb_map_offset(), since 90378e589192 ("drm/gem: drm_gem_dumb_map_offset(): reject dma-buf"), uses the obj->import_attach to reject such invalid mmaps. This prevents vgem from allowing userspace mmapping the dumb handle and attempting to incorrectly fault in remote pages belonging to another device, where there may not even be a struct page. v2: Use the default drm_gem_dumb_map_offset() callback Fixes: af33a9190d02 ("drm/vgem: Enable dmabuf import interfaces") Signed-off-by: Chris Wilson <chris(a)chris-wilson.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter(a)ffwll.ch> Cc: <stable(a)vger.kernel.org> # v4.13+ --- drivers/gpu/drm/vgem/vgem_drv.c | 27 --------------------------- 1 file changed, 27 deletions(-) diff --git a/drivers/gpu/drm/vgem/vgem_drv.c b/drivers/gpu/drm/vgem/vgem_drv.c index 909eba43664a..204d1df5a21d 100644 --- a/drivers/gpu/drm/vgem/vgem_drv.c +++ b/drivers/gpu/drm/vgem/vgem_drv.c @@ -229,32 +229,6 @@ static int vgem_gem_dumb_create(struct drm_file *file, struct drm_device *dev, return 0; } -static int vgem_gem_dumb_map(struct drm_file *file, struct drm_device *dev, - uint32_t handle, uint64_t *offset) -{ - struct drm_gem_object *obj; - int ret; - - obj = drm_gem_object_lookup(file, handle); - if (!obj) - return -ENOENT; - - if (!obj->filp) { - ret = -EINVAL; - goto unref; - } - - ret = drm_gem_create_mmap_offset(obj); - if (ret) - goto unref; - - *offset = drm_vma_node_offset_addr(&obj->vma_node); -unref: - drm_gem_object_put_unlocked(obj); - - return ret; -} - static struct drm_ioctl_desc vgem_ioctls[] = { DRM_IOCTL_DEF_DRV(VGEM_FENCE_ATTACH, vgem_fence_attach_ioctl, DRM_RENDER_ALLOW), DRM_IOCTL_DEF_DRV(VGEM_FENCE_SIGNAL, vgem_fence_signal_ioctl, DRM_RENDER_ALLOW), @@ -448,7 +422,6 @@ static struct drm_driver vgem_driver = { .fops = &vgem_driver_fops, .dumb_create = vgem_gem_dumb_create, - .dumb_map_offset = vgem_gem_dumb_map, .prime_handle_to_fd = drm_gem_prime_handle_to_fd, .prime_fd_to_handle = drm_gem_prime_fd_to_handle, -- 2.27.0

[PATCH for 5.8] sched: Fix unreliable rseq cpu_id for new tasks

by Mathieu Desnoyers

While integrating rseq into glibc and replacing glibc's sched_getcpu implementation with rseq, glibc's tests discovered an issue with incorrect __rseq_abi.cpu_id field value right after the first time a newly created process issues sched_setaffinity. For the records, it triggers after building glibc and running tests, and then issuing: for x in {1..2000} ; do posix/tst-affinity-static & done and shows up as: error: Unexpected CPU 2, expected 0 error: Unexpected CPU 2, expected 0 error: Unexpected CPU 2, expected 0 error: Unexpected CPU 2, expected 0 error: Unexpected CPU 138, expected 0 error: Unexpected CPU 138, expected 0 error: Unexpected CPU 138, expected 0 error: Unexpected CPU 138, expected 0 This is caused by the scheduler invoking __set_task_cpu() directly from sched_fork() and wake_up_new_task(), thus bypassing rseq_migrate() which is done by set_task_cpu(). Add the missing rseq_migrate() to both functions. The only other direct use of __set_task_cpu() is done by init_idle(), which does not involve a user-space task. Based on my testing with the glibc test-case, just adding rseq_migrate() to wake_up_new_task() is sufficient to fix the observed issue. Also add it to sched_fork() to keep things consistent. The reason why this never triggered so far with the rseq/basic_test selftest is unclear. The current use of sched_getcpu(3) does not typically require it to be always accurate. However, use of the __rseq_abi.cpu_id field within rseq critical sections requires it to be accurate. If it is not accurate, it can cause corruption in the per-cpu data targeted by rseq critical sections in user-space.

patch "iio:pressure:ms5611 Fix buffer element alignment" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio:pressure:ms5611 Fix buffer element alignment to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 8db4afe163bbdd93dca6fcefbb831ef12ecc6b4d Mon Sep 17 00:00:00 2001 From: Jonathan Cameron <Jonathan.Cameron(a)huawei.com> Date: Sun, 7 Jun 2020 16:53:57 +0100 Subject: iio:pressure:ms5611 Fix buffer element alignment One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses an array of smaller elements on the stack. Here there is no data leak possibility so use an explicit structure on the stack to ensure alignment and nice readable fashion.

If you have any questions about this process, please let me know. >From 3f9c6d38797e9903937b007a341dad0c251765d6 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron <Jonathan.Cameron(a)huawei.com> Date: Sun, 17 May 2020 18:29:56 +0100 Subject: iio:health:afe4403 Fix timestamp alignment and prevent data leak. One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses a 32 byte array of smaller elements on the stack. As Lars also noted this anti pattern can involve a leak of data to userspace and that indeed can happen here. We close both issues by moving to a suitable structure in the iio_priv() data with alignment explicitly requested. This data is allocated with kzalloc so no data can leak appart from previous readings.

[PATCH 1/2] drm/vgem: Do not allocate backing shmemfs file for an import dmabuf object

by Chris Wilson

If we assign obj->filp, we believe that the create vgem bo is native and allow direct operations like mmap() assuming it behaves as backed by a shmemfs inode. When imported from a dmabuf, the obj->pages are not always meaningful and the shmemfs backing store misleading. Note, that regular mmap access to a vgem bo is via the dumb buffer API, and that rejects attempts to mmap an imported dmabuf, drm_gem_dumb_map_offset(): if (obj->import_attach) return -EINVAL; So the only route by which we might accidentally allow mmapping of an imported buffer is via vgem_prime_mmap(), which checked for obj->filp assuming that it would be NULL. Well it would had it been updated to use the common drm_gem_dum_map_offset() helper, instead it has vgem_gem_dumb_map(): if (!obj->filp) return -EINVAL; falling foul of the same trap as above.

This is because of the way moved_swap accounting was saved up until the task move gets completed in __mem_cgroup_clear_mc(), deferred from when mem_cgroup_move_swap_account() actually exchanged old and new ids. Concurrent activity can free up swap quicker than the task is scanned, bringing id refcount down 0 (which should only be possible when offlining). Just skip that optimization: do that part of the accounting immediately.

This should be prevented by the check against the maximum file size, but this doesn't work because the maximum file size is read directly from the on-disk superblock and isn't validated itself.

patch "usb: chipidea: core: add wakeup support for extcon" added to usb-linus

[PATCH] blk-mq: consider non-idle request as "inflight" in blk_mq_rq_inflight()

by Mike Snitzer

From: Ming Lei <ming.lei(a)redhat.com> dm-multipath is the only user of blk_mq_queue_inflight(). When dm-multipath calls blk_mq_queue_inflight() to check if it has outstanding IO it can get a false negative. The reason for this is blk_mq_rq_inflight() doesn't consider requests that are no longer MQ_RQ_IN_FLIGHT but that are now MQ_RQ_COMPLETE (->complete isn't called or finished yet) as "inflight". This causes request-based dm-multipath's dm_wait_for_completion() to return before all outstanding dm-multipath requests have actually completed. This breaks DM multipath's suspend functionality because blk-mq requests complete after DM's suspend has finished -- which shouldn't happen.

[PATCH] x86/resctrl: Fix memory bandwidth counter width for AMD

by Babu Moger

[ Upstream commit 2c18bd525c47f882f033b0a813ecd09c93e1ecdf ] Memory bandwidth is calculated reading the monitoring counter at two intervals and calculating the delta. It is the software’s responsibility to read the count often enough to avoid having the count roll over _twice_ between reads. The current code hardcodes the bandwidth monitoring counter's width to 24 bits for AMD. This is due to default base counter width which is 24. Currently, AMD does not implement the CPUID 0xF.[ECX=1]:EAX to adjust the counter width. But, the AMD hardware supports much wider bandwidth counter with the default width of 44 bits. Kernel reads these monitoring counters every 1 second and adjusts the counter value for overflow. With 24 bits and scale value of 64 for AMD, it can only measure up to 1GB/s without overflowing. For the rates above 1GB/s this will fail to measure the bandwidth. Fix the issue setting the default width to 44 bits by adjusting the offset. AMD future products will implement CPUID 0xF.[ECX=1]:EAX.

Though you would not expect it from the source, both gccs I was using (4.8.1 and 7.5.0) had chosen to compile compact_zone_order() with the ".cc = &cc" implemented by mov %rbx,-0xb0(%rbp) immediately before callq compact_zone - long after the "current->capture_control = &capc". An interrupt in between those finds capc->cc NULL (zeroed by an earlier rep stos). This could presumably be fixed by a barrier() before setting current->capture_control in compact_zone_order(); but would also need more care on return from compact_zone(), in order not to risk leaking a page captured by interrupt just before capture_control is reset. Maybe that is the preferable fix, but I felt safer for task_capc() to exclude the rather surprising possibility of capture at interrupt time" I have checked that gcc10 also behaves the same. The advantage of fix in compact_zone_order() is that we don't add another test in the page freeing hot path, and that it might prevent future problems if we stop exposing pointers to uninitialized structures in current task. So this patch implements the suggestion for compact_zone_order() with barrier() (and WRITE_ONCE() to prevent store tearing) for setting current->capture_control, and prevents page leaking with WRITE_ONCE/READ_ONCE in the proper order.

[PATCH 1/2] pinctrl: ingenic: Enhance support for IRQ_TYPE_EDGE_BOTH

by Paul Cercueil

Ingenic SoCs don't natively support registering an interrupt for both rising and falling edges. This has to be emulated in software. Until now, this was emulated by switching back and forth between IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING according to the level of the GPIO. While this worked most of the time, when used with GPIOs that need debouncing, some events would be lost. For instance, between the time a falling-edge interrupt happens and the interrupt handler configures the hardware for rising-edge, the level of the pin may have already risen, and the rising-edge event is lost. To address that issue, instead of switching back and forth between IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING, we now switch back and forth between IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH. Since we always switch in the interrupt handler, they actually permit to detect level changes. In the example above, if the pin level rises before switching the IRQ type from IRQ_TYPE_LEVEL_LOW to IRQ_TYPE_LEVEL_HIGH, a new interrupt will raise as soon as the handler exits, and the rising-edge event will be properly detected.

[RFC PATCH for 5.8 1/4] sched: Fix unreliable rseq cpu_id for new tasks

by Mathieu Desnoyers

While integrating rseq into glibc and replacing glibc's sched_getcpu implementation with rseq, glibc's tests discovered an issue with incorrect __rseq_abi.cpu_id field value right after the first time a newly created process issues sched_setaffinity. For the records, it triggers after building glibc and running tests, and then issuing: for x in {1..2000} ; do posix/tst-affinity-static & done and shows up as: error: Unexpected CPU 2, expected 0 error: Unexpected CPU 2, expected 0 error: Unexpected CPU 2, expected 0 error: Unexpected CPU 2, expected 0 error: Unexpected CPU 138, expected 0 error: Unexpected CPU 138, expected 0 error: Unexpected CPU 138, expected 0 error: Unexpected CPU 138, expected 0 This is caused by the scheduler invoking __set_task_cpu() directly from sched_fork() and wake_up_new_task(), thus bypassing rseq_migrate() which is done by set_task_cpu(). Add the missing rseq_migrate() to both functions. The only other direct use of __set_task_cpu() is done by init_idle(), which does not involve a user-space task. Based on my testing with the glibc test-case, just adding rseq_migrate() to wake_up_new_task() is sufficient to fix the observed issue. Also add it to sched_fork() to keep things consistent. The reason why this never triggered so far with the rseq/basic_test selftest is unclear. The current use of sched_getcpu(3) does not typically require it to be always accurate. However, use of the __rseq_abi.cpu_id field within rseq critical sections requires it to be accurate. If it is not accurate, it can cause corruption in the per-cpu data targeted by rseq critical sections in user-space.

[PATCH] drm/i915/gt: Pin the rings before marking active

by Chris Wilson

On eviction, we acquire the vm->mutex and then wait on the vma->active. Thereore when binding and pinning the vma, we must follow the same sequennce, lock/pin the vma then mark it active. Otherwise, we mark the vma as active, then wait for the vm->mutex, and meanwhile the evictor waits upon us.

[PATCH v7 0/2] Renovate memcpy_mcsafe with copy_mc_to_{user, kernel}

by Dan Williams

Changes since v6 [1]: - Collected Tony's Reviewed-by. - Rebased on v5.8-rc3 to address a conflict with commit e3a9e681adb7 ("x86/entry: Fixup bad_iret vs noinstr") No other functional changes, and no other comments since v5. At this point I think I'll go ahead with pushing to -next to get it some soak time for a potential v5.9 merge and catch any other conflicts that might arise in the meantime. Of course, I'll immediately drop it from -next if x86.tip picks it up or naks it. As it stands, nothing queued in x86.tip/master conflicts with these. [1]: http://lore.kernel.org/r/159244031857.1107636.5054974045023236143.stgit@dwi… --- The primary motivation to go touch memcpy_mcsafe() is that the existing benefit of doing slow and careful copies is obviated on newer CPUs. That fact solves the problem of needing to detect machine-check recovery capability. Now the old "mcsafe_key" opt-in to careful copying can be made an opt-out from the default fast copy implementation. The discussion with Linus further made clear that this facility had already lost its x86-machine-check specificity starting with commit 2c89130a56a ("x86/asm/memcpy_mcsafe: Add write-protection-fault handling"). The new changes to not require a "careful copy" further de-emphasizes the role that x86-MCA plays in the implementation to just one more source of recoverable trap during the operation. With the above realizations the name "mcsafe" is no longer accurate and copy_safe() is proposed as its replacement. x86 grows a copy_safe_fast() implementation as a default implementation that is independent of detecting the presence of x86-MCA. --- Dan Williams (2): x86, powerpc: Rename memcpy_mcsafe() to copy_mc_to_{user,kernel}() x86/copy_mc: Introduce copy_mc_generic() arch/powerpc/Kconfig | 2 arch/powerpc/include/asm/string.h | 2 arch/powerpc/include/asm/uaccess.h | 40 +++-- arch/powerpc/lib/Makefile | 2 arch/powerpc/lib/copy_mc_64.S | 4 arch/x86/Kconfig | 2 arch/x86/Kconfig.debug | 2 arch/x86/include/asm/copy_mc_test.h | 75 +++++++++ arch/x86/include/asm/mcsafe_test.h | 75 --------- arch/x86/include/asm/string_64.h | 32 ---- arch/x86/include/asm/uaccess.h | 21 +++ arch/x86/include/asm/uaccess_64.h | 20 -- arch/x86/kernel/cpu/mce/core.c | 8 - arch/x86/kernel/quirks.c | 9 - arch/x86/lib/Makefile | 1 arch/x86/lib/copy_mc.c | 64 ++++++++ arch/x86/lib/copy_mc_64.S | 165 ++++++++++++++++++++ arch/x86/lib/memcpy_64.S | 115 -------------- arch/x86/lib/usercopy_64.c | 21 --- drivers/md/dm-writecache.c | 15 +- drivers/nvdimm/claim.c | 2 drivers/nvdimm/pmem.c | 6 - include/linux/string.h | 9 - include/linux/uaccess.h | 9 + include/linux/uio.h | 10 + lib/Kconfig | 7 + lib/iov_iter.c | 43 +++-- tools/arch/x86/include/asm/mcsafe_test.h | 13 -- tools/arch/x86/lib/memcpy_64.S | 115 -------------- tools/objtool/check.c | 5 - tools/perf/bench/Build | 1 tools/perf/bench/mem-memcpy-x86-64-lib.c | 24 --- tools/testing/nvdimm/test/nfit.c | 48 +++--- .../testing/selftests/powerpc/copyloops/.gitignore | 2 tools/testing/selftests/powerpc/copyloops/Makefile | 6 - .../selftests/powerpc/copyloops/copy_mc_64.S | 1 .../selftests/powerpc/copyloops/memcpy_mcsafe_64.S | 1 37 files changed, 451 insertions(+), 526 deletions(-) rename arch/powerpc/lib/{memcpy_mcsafe_64.S => copy_mc_64.S} (98%) create mode 100644 arch/x86/include/asm/copy_mc_test.h delete mode 100644 arch/x86/include/asm/mcsafe_test.h create mode 100644 arch/x86/lib/copy_mc.c create mode 100644 arch/x86/lib/copy_mc_64.S delete mode 100644 tools/arch/x86/include/asm/mcsafe_test.h delete mode 100644 tools/perf/bench/mem-memcpy-x86-64-lib.c create mode 120000 tools/testing/selftests/powerpc/copyloops/copy_mc_64.S delete mode 120000 tools/testing/selftests/powerpc/copyloops/memcpy_mcsafe_64.S

[PATCH] tpm: Define TPM2_SPACE_BUFFER_SIZE to replace the use of PAGE_SIZE

by Jarkko Sakkinen

The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64).

[PATCH v2 3/4] arm64: arch_timer: Disable the compat vdso for cores affected by ARM64_WORKAROUND_1418040

by Marc Zyngier

ARM64_WORKAROUND_1418040 requires that AArch32 EL0 accesses to the virtual counter register are trapped and emulated by the kernel.

[PATCH] coresight: etm4x: Fix save/restore during cpu idle

[PATCH][v2] Drivers: hv: Change flag to write log level in panic msg to false

by Joseph Salisbury

When the kernel panics, one page of kmsg data may be collected and sent to Hyper-V to aid in diagnosing the failure. The collected kmsg data typically contains 50 to 100 lines, each of which has a log level prefix that isn't very useful from a diagnostic standpoint. So tell kmsg_dump_get_buffer() to not include the log level, enabling more information that *is* useful to fit in the page.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From ce593a6c480a22acba08795be313c0c6d49dd35d Mon Sep 17 00:00:00 2001 From: Jens Axboe <axboe(a)kernel.dk> Date: Tue, 30 Jun 2020 12:39:05 -0600 Subject: [PATCH] io_uring: use signal based task_work running Since 5.7, we've been using task_work to trigger async running of requests in the context of the original task. This generally works great, but there's a case where if the task is currently blocked in the kernel waiting on a condition to become true, it won't process task_work. Even though the task is woken, it just checks whatever condition it's waiting on, and goes back to sleep if it's still false. This is a problem if that very condition only becomes true when that task_work is run. An example of that is the task registering an eventfd with io_uring, and it's now blocked waiting on an eventfd read. That read could depend on a completion event, and that completion event won't get trigged until task_work has been run. Use the TWA_SIGNAL notification for task_work, so that we ensure that the task always runs the work when queued.

[FOR-STABLE-3.9+] sched/rt: Show the 'sched_rr_timeslice' SCHED_RR timeslice tuning knob in milliseconds

by Viresh Kumar

From: Shile Zhang <shile.zhang(a)nokia.com> We added the 'sched_rr_timeslice_ms' SCHED_RR tuning knob in this commit: ce0dbbbb30ae ("sched/rt: Add a tuning knob to allow changing SCHED_RR timeslice") ... which name suggests to users that it's in milliseconds, while in reality it's being set in milliseconds but the result is shown in jiffies. This is obviously confusing when HZ is not 1000, it makes it appear like the value set failed, such as HZ=100: root# echo 100 > /proc/sys/kernel/sched_rr_timeslice_ms root# cat /proc/sys/kernel/sched_rr_timeslice_ms 10 Fix this to be milliseconds all around.

[PATCH] MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen

by Hauke Mehrtens

This resolves the hazard between the mtc0 in the change_c0_status() and the mfc0 in configure_exception_vector(). Without resolving this hazard configure_exception_vector() could read an old value and would restore this old value again. This would revert the changes change_c0_status() did. I checked this by printing out the read_c0_status() at the end of per_cpu_trap_init() and the ST0_MX is not set without this patch. The hazard is documented in the MIPS Architecture Reference Manual Vol. III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev 6.03 table 8.1 which includes: Producer | Consumer | Hazard ----------|----------|---------------------------- mtc0 | mfc0 | any coprocessor 0 register I saw this hazard on an Atheros AR9344 rev 2 SoC with a MIPS 74Kc CPU. There the change_c0_status() function would activate the DSPen by setting ST0_MX in the c0_status register. This was reverted and then the system got a DSP exception when the DSP registers were saved in save_dsp() in the first process switch. The crash looks like this: [ 0.089999] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.097796] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.107070] Kernel panic - not syncing: Unexpected DSP exception [ 0.113470] Rebooting in 1 seconds.. We saw this problem in OpenWrt only on the MIPS 74Kc based Atheros SoCs, not on the 24Kc based SoCs. We only saw it with kernel 5.4 not with kernel 4.19, in addition we had to use GCC 8.4 or 9.X, with GCC 8.3 it did not happen. In the kernel I bisected this problem to commit 9012d011660e ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING"), but when this was reverted it also happened after commit 172dcd935c34b ("MIPS: Always allocate exception vector for MIPSr2+"). Commit 0b24cae4d535 ("MIPS: Add missing EHB in mtc0 -> mfc0 sequence.") does similar changes to a different file. I am not sure if there are more places affected by this problem.

[patch 3/5] mm/cma.c: use exact_nid true to fix possible per-numa cma leak

by Andrew Morton

From: Barry Song <song.bao.hua(a)hisilicon.com> Subject: mm/cma.c: use exact_nid true to fix possible per-numa cma leak Calling cma_declare_contiguous_nid() with false exact_nid for per-numa reservation can easily cause cma leak and various confusion. For example, mm/hugetlb.c is trying to reserve per-numa cma for gigantic pages. But it can easily leak cma and make users confused when system has memoryless nodes. In case the system has 4 numa nodes, and only numa node0 has memory. if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4 different numa nodes. since exact_nid=false in current code, all 4 numa nodes will get cma successfully from node0, but hugetlb_cma[1 to 3] will never be available to hugepage will only allocate memory from hugetlb_cma[0]. In case the system has 4 numa nodes, both numa node0&2 has memory, other nodes have no memory. if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4 different numa nodes. since exact_nid=false in current code, all 4 numa nodes will get cma successfully from node0 or 2, but hugetlb_cma[1] and [3] will never be available to hugepage as mm/hugetlb.c will only allocate memory from hugetlb_cma[0] and hugetlb_cma[2]. This causes permanent leak of the cma areas which are supposed to be used by memoryless node. Of cource we can workaround the issue by letting mm/hugetlb.c scan all cma areas in alloc_gigantic_page() even node_mask includes node0 only. that means when node_mask includes node0 only, we can get page from hugetlb_cma[1] to hugetlb_cma[3]. But this will cause kernel crash in free_gigantic_page() while it wants to free page by: cma_release(hugetlb_cma[page_to_nid(page)], page, 1 << order) On the other hand, exact_nid=false won't consider numa distance, it might be not that useful to leverage cma areas on remote nodes. I feel it is much simpler to make exact_nid true to make everything clear. After that, memoryless nodes won't be able to reserve per-numa CMA from other nodes which have memory.

[patch 1/5] mm/hugetlb.c: fix pages per hugetlb calculation

by Andrew Morton

From: Mike Kravetz <mike.kravetz(a)oracle.com> Subject: mm/hugetlb.c: fix pages per hugetlb calculation The routine hpage_nr_pages() was incorrectly used to calculate the number of base pages in a hugetlb page. hpage_nr_pages is designed to be called for THP pages and will return HPAGE_PMD_NR for hugetlb pages of any size. Due to the context in which hpage_nr_pages was called, it is unlikely to produce a user visible error. The routine with the incorrect call is only exercised in the case of hugetlb memory error or migration. In addition, this would need to be on an architecture which supports huge page sizes less than PMD_SIZE. And, the vma containing the huge page would also need to smaller than PMD_SIZE.

[PATCH v4] ima: move APPRAISE_BOOTPARAM dependency on ARCH_POLICY to runtime

by Bruno Meneguele

APPRAISE_BOOTPARAM has been marked as dependent on !ARCH_POLICY in compile time, enforcing the appraisal whenever the kernel had the arch policy option enabled. However it breaks systems where the option is set but the system wasn't booted in a "secure boot" platform. In this scenario, anytime an appraisal policy (i.e. ima_policy=appraisal_tcb) is used it will be forced, giving no chance to the user set the 'fix' state (ima_appraise=fix) to actually measure system's files. Considering the ARCH_POLICY is only effective when secure boot is actually enabled this patch remove the compile time dependency and move it to a runtime decision, based on the secure boot state of that platform.

Since we are on this subject, LTP af_alg02 test case fails on stable 4.9 and stable 4.4 This is not a regression because the test case has been failing from the beginning.

[PATCH] crypto: ccp - Fix use of merged scatterlists

by John Allen

Running the crypto manager self tests with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS may result in several types of errors when using the ccp-crypto driver: alg: skcipher: cbc-des3-ccp encryption failed on test vector 0; expected_error=0, actual_error=-5 ... alg: skcipher: ctr-aes-ccp decryption overran dst buffer on test vector 0 ... alg: ahash: sha224-ccp test failed (wrong result) on test vector ... These errors are the result of improper processing of scatterlists mapped for DMA. Given a scatterlist in which entries are merged as part of mapping the scatterlist for DMA, the DMA length of a merged entry will reflect the combined length of the entries that were merged. The subsequent scatterlist entry will contain DMA information for the scatterlist entry after the last merged entry, but the non-DMA information will be that of the first merged entry. The ccp driver does not take this scatterlist merging into account. To address this, add a second scatterlist pointer to track the current position in the DMA mapped representation of the scatterlist. Both the DMA representation and the original representation of the scatterlist must be tracked as while most of the driver can use just the DMA representation, scatterlist_map_and_copy() must use the original representation and expects the scatterlist pointer to be accurate to the original representation. In order to properly walk the original scatterlist, the scatterlist must be walked until the combined lengths of the entries seen is equal to the DMA length of the current entry being processed in the DMA mapped representation.

[PATCH 5/5] bpf: Check correct cred for CAP_SYSLOG in bpf_dump_raw_ok()

by Kees Cook

When evaluating access control over kallsyms visibility, credentials at open() time need to be used, not the "current" creds (though in BPF's case, this has likely always been the same). Plumb access to associated file->f_cred down through bpf_dump_raw_ok() and its callers now that kallsysm_show_value() has been refactored to take struct cred.

[PATCH v2 1/4] arm64: ptrace: Add a comment describing our syscall entry/exit trap ABI

by Will Deacon

Our tracehook logic for syscall entry/exit raises a SIGTRAP back to the tracer following a ptrace request such as PTRACE_SYSCALL. As part of this procedure, we clobber the reported value of one of the tracee's general purpose registers (x7 for native tasks, r12 for compat) to indicate whether the stop occurred on syscall entry or exit. This is a slightly unfortunate ABI, as it prevents the tracer from accessing the real register value and is at odds with other similar stops such as seccomp traps. Since we're stuck with this ABI, expand the comment in our tracehook logic to acknowledge the issue and descibe the behaviour in more detail.

[PATCH] tpm: Define TPM2_SPACE_BUFFER_SIZE to replace the use of PAGE_SIZE

The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64).

These preallocated extents have, and must have, the same size that extents from the data block group being relocated have. Later before we start the relocation stage that updates pointers (bytenr field of file extent items) to point to the the new extents, we trigger writeback for the data relocation inode. The expectation is that writeback will write the pages to the previously preallocated extents, that it follows the NOCOW path. That is generally the case, however, if a scrub is running it may have turned the block group that contains those extents into RO mode, in which case writeback falls back to the COW path. However in the COW path instead of allocating exactly one extent with the expected size, the allocator may end up allocating several smaller extents due to free space fragmentation - because we tell it at cow_file_range() that the minimum allocation size can match the filesystem's sector size. This later breaks the relocation's expectation that an extent associated to a file extent item in the data relocation inode has the same size as the respective extent pointed by a file extent item in another tree - in this case the extent to which the relocation inode poins to is smaller, causing relocation.c:get_new_location() to return -EINVAL. For example, if we are relocating a data block group X that has a logical address of X and the block group has an extent allocated at the logical address X + 128KiB with a size of 64KiB: 1) At prealloc_file_extent_cluster() we allocate an extent for the data relocation inode with a size of 64KiB and associate it to the file offset 128KiB (X + 128KiB - X) of the data relocation inode. This preallocated extent was allocated at block group Z; 2) A scrub running in parallel turns block group Z into RO mode and starts scrubing its extents; 3) Relocation triggers writeback for the data relocation inode; 4) When running delalloc (btrfs_run_delalloc_range()), we try first the NOCOW path because the data relocation inode has BTRFS_INODE_PREALLOC set in its flags. However, because block group Z is in RO mode, the NOCOW path (run_delalloc_nocow()) falls back into the COW path, by calling cow_file_range(); 5) At cow_file_range(), in the first iteration of the while loop we call btrfs_reserve_extent() to allocate a 64KiB extent and pass it a minimum allocation size of 4KiB (fs_info->sectorsize). Due to free space fragmentation, btrfs_reserve_extent() ends up allocating two extents of 32KiB each, each one on a different iteration of that while loop; 6) Writeback of the data relocation inode completes; 7) Relocation proceeds and ends up at relocation.c:replace_file_extents(), with a leaf which has a file extent item that points to the data extent from block group X, that has a logical address (bytenr) of X + 128KiB and a size of 64KiB. Then it calls get_new_location(), which does a lookup in the data relocation tree for a file extent item starting at offset 128KiB (X + 128KiB - X) and belonging to the data relocation inode. It finds a corresponding file extent item, however that item points to an extent that has a size of 32KiB, which doesn't match the expected size of 64KiB, resuling in -EINVAL being returned from this function and propagated up to __btrfs_cow_block(), which aborts the current transaction. To fix this make sure that at cow_file_range() when we call the allocator we pass it a minimum allocation size corresponding the desired extent size if the inode belongs to the data relocation tree, otherwise pass it the filesystem's sector size as the minimum allocation size.

When this happens we end up failing the block group creation with an error -EEXIST since we attempt to insert a duplicate block group item key in the extent tree. That results in a transaction abort. The race happens like this: 1) Task A is doing a fitrim, and at btrfs_trim_block_group() it freezes block group X with btrfs_freeze_block_group() (until very recently that was named btrfs_get_block_group_trimming()); 2) Task B starts removing block group X, either because it's now unused or due to relocation for example. So at btrfs_remove_block_group(), while holding the chunk mutex and the block group's lock, it sets the 'removed' flag of the block group and it sets the local variable 'remove_em' to false, because the block group is currently frozen (its 'frozen' counter is > 0, until very recently this counter was named 'trimming'); 3) Task B unlocks the block group and the chunk mutex; 4) Task A is done trimming the block group and unfreezes the block group by calling btrfs_unfreeze_block_group() (until very recently this was named btrfs_put_block_group_trimming()). In this function we lock the block group and set the local variable 'cleanup' to true because we were able to decrement the block group's 'frozen' counter down to 0 and the flag 'removed' is set in the block group. Since 'cleanup' is set to true, it locks the chunk mutex and removes the extent mapping representing the block group from the mapping tree; 5) Task C allocates a new block group Y and it picks up the logical address that block group X had as the logical address for Y, because X was the block group with the highest logical address and now the second block group with the highest logical address, the last in the fs mapping tree, ends at an offset corresponding to block group X's logical address (this logical address selection is done at volumes.c:find_next_chunk()). At this point the new block group Y does not have yet its item added to the extent tree (nor the corresponding device extent items and chunk item in the device and chunk trees). The new group Y is added to the list of pending block groups in the transaction handle; 6) Before task B proceeds to removing the block group item for block group X from the extent tree, which has a key matching: (X logical offset, BTRFS_BLOCK_GROUP_ITEM_KEY, length) task C while ending its transaction handle calls btrfs_create_pending_block_groups(), which finds block group Y and tries to insert the block group item for Y into the exten tree, which fails with -EEXIST since logical offset is the same that X had and task B hasn't yet deleted the key from the extent tree. This failure results in a transaction abort, producing a stack like the following: ------------[ cut here ]------------ BTRFS: Transaction aborted (error -17) WARNING: CPU: 2 PID: 19736 at fs/btrfs/block-group.c:2074 btrfs_create_pending_block_groups+0x1eb/0x260 [btrfs] Modules linked in: btrfs blake2b_generic xor raid6_pq (...)

There is a second bug where if removing the free space tree entries (the call to remove_block_group_free_space()) fails we end up jumping to the 'out_put_group' label but end up decrementing the reference count only once, when we should have done it twice, since we have already removed the block group from the block group cache rbtree. This happens because the reference count decrement for the rbtree reference happens after attempting to remove the free space tree entries, which is far away from the place where we remove the block group from the rbtree. To make things less error prone, decrement the reference count for the rbtree immediately after removing the block group from it. This also eleminates the need for two different exit labels on error, renaming 'out_put_label' to just 'out' and removing the old 'out'.

[PATCH 1/3] mm/vmscan: restore zone_reclaim_mode ABI

by Dave Hansen

From: Dave Hansen <dave.hansen(a)linux.intel.com> I went to go add a new RECLAIM_* mode for the zone_reclaim_mode sysctl. Like a good kernel developer, I also went to go update the documentation. I noticed that the bits in the documentation didn't match the bits in the #defines. The VM never explicitly checks the RECLAIM_ZONE bit. The bit is, however implicitly checked when checking 'node_reclaim_mode==0'. The RECLAIM_ZONE #define was removed in a cleanup. That, by itself is fine. But, when the bit was removed (bit 0) the _other_ bit locations also got changed. That's not OK because the bit values are documented to mean one specific thing and users surely rely on them meaning that one thing and not changing from kernel to kernel. The end result is that if someone had a script that did: sysctl vm.zone_reclaim_mode=1 That script went from doing nothing to writing out pages during node reclaim after the commit in question. That's not great. Put the bits back the way they were and add a comment so something like this is a bit harder to do again. Update the documentation to make it clear that the first bit is ignored.

drm/i915: use forced codec wake on all gen9+ platforms

by Kai Vehmanen

Hey, following commit from 5.8-rc1 would be beneficial for 5.4+ kernels. We've verified it fixes audio driver probe errors on systems with Intel gen10/11/12 display hardware: Link: https://github.com/thesofproject/linux/issues/1847 commit 1c664c15cf0a31784b217a84fa0128ce46f17a84 Author: Kai Vehmanen <kai.vehmanen(a)linux.intel.com> Date: Tue Mar 24 17:32:12 2020 +0200 drm/i915: use forced codec wake on all gen9+ platforms Commit 632f3ab95fe2 ("drm/i915/audio: add codec wakeup override enabled/disable callback"), added logic to toggle Codec Wake on gen9. This is used by audio driver when it resets the HDA controller. It seems explicit toggling of the wakeline can help to fix problems with probe failing on some gen12 platforms. And based on specs, there is no reason why this programming sequence should not be applied to all gen9+ platforms. No side-effects are seen on gen10/11. So apply the wake-logic to all gen9+ platforms.

[PATCH v2 0/1] Revert "serial: 8250: Fix max baud limit in generic 8250 port"

by Daniel Winkler

This change regresses the QCA6174A-3 bluetooth chip, preventing firmware from being properly loaded. Without this change, the chip works as intended. The device is the Kukui Chromebook using the Mediatek chipset and the 8250_mtk uart. Initial controller baudrate is 115200 and operating speed is 3000000. Our entire suite of bluetooth tests now fail on this platform due to an apparent failure to sync its firmware on initialization. The driver is in the cros tree at drivers/bluetooth/hci_qca.c and uses the serdev interface. Specifically, this is the QCA_ROME chipset.

Request for patch inclusion for 5.4-stable

by Jens Axboe

Hi, There's no upstream variant of this, as that would require backporting all the io-wq changes from 5.5 and on. Hence I made a one-off that ensures that we don't leak memory if we have async work items that need active cancelation (like socket IO). Can we get this queued up for 5.4? I've tested it and the original reporter has as well. From: Jens Axboe <axboe(a)kernel.dk> Subject: [PATCH] io_uring: make sure async workqueue is canceled on exit Track async work items that we queue, so we can safely cancel them if the ring is closed or the process exits. Newer kernels handle this automatically with io-wq, but the old workqueue based setup needs a bit of special help to get there.

[PATCH AUTOSEL 4.4 1/7] net: usb: ax88179_178a: fix packet alignment padding

by Sasha Levin

From: Jeremy Kerr <jk(a)ozlabs.org> [ Upstream commit e869e7a17798d85829fa7d4f9bbe1eebd4b2d3f6 ] Using a AX88179 device (0b95:1790), I see two bytes of appended data on every RX packet. For example, this 48-byte ping, using 0xff as a payload byte: 04:20:22.528472 IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 2447, seq 1, length 64 0x0000: 000a cd35 ea50 000a cd35 ea4f 0800 4500 0x0010: 0054 c116 4000 4001 f63e c0a8 0101 c0a8 0x0020: 0102 0800 b633 098f 0001 87ea cd5e 0000 0x0030: 0000 dcf2 0600 0000 0000 ffff ffff ffff 0x0040: ffff ffff ffff ffff ffff ffff ffff ffff 0x0050: ffff ffff ffff ffff ffff ffff ffff ffff 0x0060: ffff 961f Those last two bytes - 96 1f - aren't part of the original packet. In the ax88179 RX path, the usbnet rx_fixup function trims a 2-byte 'alignment pseudo header' from the start of the packet, and sets the length from a per-packet field populated by hardware. It looks like that length field *includes* the 2-byte header; the current driver assumes that it's excluded. This change trims the 2-byte alignment header after we've set the packet length, so the resulting packet length is correct. While we're moving the comment around, this also fixes the spelling of 'pseudo'. Signed-off-by: Jeremy Kerr <jk(a)ozlabs.org> Signed-off-by: David S.

[PATCH AUTOSEL 4.9 01/13] gpu: host1x: Detach driver on unregister

by Sasha Levin

From: Thierry Reding <treding(a)nvidia.com> [ Upstream commit d9a0a05bf8c76e6dc79230669a8b5d685b168c30 ] Currently when a host1x device driver is unregistered, it is not detached from the host1x controller, which means that the device will stay around and when the driver is registered again, it may bind to the old, stale device rather than the new one that was created from scratch upon driver registration. This in turn can cause various weird crashes within the driver core because it is confronted with a device that was already deleted. Fix this by detaching the driver from the host1x controller when it is unregistered. This ensures that the deleted device also is no longer present in the device list that drivers will bind to.

[PATCH AUTOSEL 4.14 01/17] ARM: dts: omap4-droid4: Fix spi configuration and increase rate

by Sasha Levin

From: Tony Lindgren <tony(a)atomide.com> [ Upstream commit 0df12a01f4857495816b05f048c4c31439446e35 ] We can currently sometimes get "RXS timed out" errors and "EOT timed out" errors with spi transfers. These errors can be made easy to reproduce by reading the cpcap iio values in a loop while keeping the CPUs busy by also reading /dev/urandom. The "RXS timed out" errors we can fix by adding spi-cpol and spi-cpha in addition to the spi-cs-high property we already have. The "EOT timed out" errors we can fix by increasing the spi clock rate to 9.6 MHz. Looks similar MC13783 PMIC says it works at spi clock rates up to 20 MHz, so let's assume we can pick any rate up to 20 MHz also for cpcap.

[net-next 10/12] iavf: Fix updating statistics

by Tony Nguyen

Commit bac8486116b0 ("iavf: Refactor the watchdog state machine") inverted the logic for when to update statistics. Statistics should be updated when no other commands are pending, instead they were only requested when a command was processed. iavf_request_stats() would see a pending request and not request statistics to be updated. This caused statistics to never be updated; fix the logic.

[PATCH] Drivers: hv: Change flag to write log level in panic msg to false

by Joseph Salisbury

When the kernel panics, one page worth of kmsg data is written to an allocated page. The Hypervisor is notified of the page address trough the MSR. This panic information is collected on the host. Since we are only collecting one page of data, the full panic message may not be collected. Each line of the panic message is prefixed with the log level of that particular message in the form <N>, where N is the log level. The typical 4 Kbytes contains anywhere from 50 to 100 lines with that log level prefix. hv_dmsg_dump() makes a call to kmsg_dump_get_buffer(). The second argument in the call is a bool described as: ‘@syslog: include the “<4>” Prefixes’. With this change, we will not write the log level to the allocated page. This will provide additional room in the allocated page for more informative panic information. Requesting in stable kernels, since many kernels running in production are stable releases.

patch "coresight: etmv4: Fix CPU power management setup in probe() function" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled coresight: etmv4: Fix CPU power management setup in probe() function to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 9b6a3f3633a5cc928b78627764793b60cb62e0f6 Mon Sep 17 00:00:00 2001 From: Mike Leach <mike.leach(a)linaro.org> Date: Wed, 1 Jul 2020 10:08:52 -0600 Subject: coresight: etmv4: Fix CPU power management setup in probe() function The current probe() function calls a pair of cpuhp_xxx API functions to setup CPU hotplug handling. The hotplug lock is held for the duration of the two calls and other CPU related code using cpus_read_lock() / cpus_read_unlock() calls. The problem is that on error states, goto: statements bypass the cpus_read_unlock() call. This code has increased in complexity as the driver has developed. This patch introduces a pair of helper functions etm4_pm_setup_cpuslocked() and etm4_pm_clear() which correct the issues above and group the PM code a little better. The two functions etm4_cpu_pm_register() and etm4_cpu_pm_unregister() are dropped as these call cpu_pm_register_notifier() / ..unregister_notifier() dependent on CONFIG_CPU_PM - but this define is used to nop these functions out in the pm headers - so the wrapper functions are superfluous.

[PATCH 2/3] uio_pdrv_genirq: fix use without device tree and no interrupt

by Esben Haabendal

While e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no interrupt") added support for using uio_pdrv_genirq for devices without interrupt for device tree platforms, the removal of uio_pdrv in 26dac3c49d56 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead") broke the support for non device tree platforms. This change fixes this, so that uio_pdrv_genirq can be used without interrupt on all platforms. This still leaves the support that uio_pdrv had for custom interrupt handler lacking, as uio_pdrv_genirq does not handle it (yet). Fixes: 26dac3c49d56 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead") Signed-off-by: Esben Haabendal <esben(a)geanix.com> Cc: stable(a)vger.kernel.org --- drivers/uio/uio_pdrv_genirq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/uio/uio_pdrv_genirq.c b/drivers/uio/uio_pdrv_genirq.c index 1d69dd49c6d2..b60173bc93ce 100644 --- a/drivers/uio/uio_pdrv_genirq.c +++ b/drivers/uio/uio_pdrv_genirq.c @@ -161,7 +161,7 @@ static int uio_pdrv_genirq_probe(struct platform_device *pdev) if (!uioinfo->irq) { ret = platform_get_irq_optional(pdev, 0); uioinfo->irq = ret; - if (ret == -ENXIO && pdev->dev.of_node) + if (ret == -ENXIO) uioinfo->irq = UIO_IRQ_NONE; else if (ret == -EPROBE_DEFER) return ret; -- 2.4.11

[PATCH 1/3] uio_pdrv_genirq: Remove warning when irq is not specified

Since e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no interrupt"), the uio_pdrv_genirq has supported use without interrupt, so the change in 7723f4c5ecdb ("driver core: platform: Add an error message to") added false warnings for those cases.

[PATCH 1/2] powerpc/mmu_gather: enable RCU_TABLE_FREE even for !SMP case

by Santosh Sivaraj

From: "Aneesh Kumar K.V" <aneesh.kumar(a)linux.ibm.com> commit 12e4d53f3f04e81f9e83d6fc10edc7314ab9f6b9 upstream The TLB flush optimisation (a46cc7a90f: powerpc/mm/radix: Improve TLB/PWC flushes) may result in random memory corruption. On any SMP system, freeing page directories should observe the exact same order as normal page freeing: 1) unhook page/directory 2) TLB invalidate 3) free page/directory Without this, any concurrent page-table walk could end up with a Use-after-Free. This is esp. trivial for anything that has software page-table walkers (HAVE_FAST_GUP / software TLB fill) or the hardware caches partial page-walks (ie. caches page directories). Even on UP this might give issues since mmu_gather is preemptible these days. An interrupt or preempted task accessing user pages might stumble into the free page if the hardware caches page directories. !SMP case is right now broken for radix translation w.r.t page walk cache flush. We can get interrupted in between page table free and that would imply we have page walk cache entries pointing to tables which got freed already. Michael said "both our platforms that run on Power9 force SMP on in Kconfig, so the !SMP case is unlikely to be a problem for anyone in practice, unless they've hacked their kernel to build it !SMP."

[PATCH 2/2] io_uring: use signal based task_work running

by Jens Axboe

Since 5.7, we've been using task_work to trigger async running of requests in the context of the original task. This generally works great, but there's a case where if the task is currently blocked in the kernel waiting on a condition to become true, it won't process task_work. Even though the task is woken, it just checks whatever condition it's waiting on, and goes back to sleep if it's still false. This is a problem if that very condition only becomes true when that task_work is run. An example of that is the task registering an eventfd with io_uring, and it's now blocked waiting on an eventfd read. That read could depend on a completion event, and that completion event won't get trigged until task_work has been run. Use the TWA_SIGNAL notification for task_work, so that we ensure that the task always runs the work when queued.

[PATCH 1/2] task_work: teach task_work_add() to do signal_wake_up()

by Jens Axboe

From: Oleg Nesterov <oleg(a)redhat.com> So that the target task will exit the wait_event_interruptible-like loop and call task_work_run() asap. The patch turns "bool notify" into 0,TWA_RESUME,TWA_SIGNAL enum, the new TWA_SIGNAL flag implies signal_wake_up(). However, it needs to avoid the race with recalc_sigpending(), so the patch also adds the new JOBCTL_TASK_WORK bit included in JOBCTL_PENDING_MASK. TODO: once this patch is merged we need to change all current users of task_work_add(notify = true) to use TWA_RESUME.

[PATCH] drm/i915: Skip stale object handle for debugfs per-file-stats

by Chris Wilson

As we close a handle GEM object, we update the drm_file's idr with an error pointer to indicate the in-progress closure, and finally set it to NULL. If we read the idr directly, we may then see an invalid object pointer, and in our debugfs per_file_stats() we therefore need to protect against the entry being invalid.

[PATCH] nvme: validate cntlid's only for nvme >= 1.1.0

by Maximilian Heyne

Controller ID's (cntlid) for NVMe devices were introduced in version 1.1.0 of the specification. Controllers that follow the older 1.0.0 spec don't set this field so it doesn't make sense to validate it. On the contrary, when using SR-IOV this check breaks VFs as they are all part of the same NVMe subsystem.

[PATCH v4] btrfs: pass checksum type via BTRFS_IOC_FS_INFO ioctl

by Johannes Thumshirn

With the recent addition of filesystem checksum types other than CRC32c, it is not anymore hard-coded which checksum type a btrfs filesystem uses. Up to now there is no good way to read the filesystem checksum, apart from reading the filesystem UUID and then query sysfs for the checksum type. Add a new csum_type and csum_size fields to the BTRFS_IOC_FS_INFO ioctl command which usually is used to query filesystem features. Also add a flags member indicating that the kernel responded with a set csum_type and csum_size field. For compatibility reasons, only return the csum_type and csum_size if the BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE flag was passed to the kernel. Also clear any unknown flags so we don't pass false positives to user-space newer than the kernel. To simplify further additions to the ioctl, also switch the padding to a u8 array. Pahole was used to verify the result of this switch: pahole -C btrfs_ioctl_fs_info_args fs/btrfs/btrfs.ko struct btrfs_ioctl_fs_info_args { __u64 max_id; /* 0 8 */ __u64 num_devices; /* 8 8 */ __u8 fsid[16]; /* 16 16 */ __u32 nodesize; /* 32 4 */ __u32 sectorsize; /* 36 4 */ __u32 clone_alignment; /* 40 4 */ __u32 flags; /* 44 4 */ __u16 csum_type; /* 48 2 */ __u16 csum_size; /* 50 2 */ __u8 reserved[972]; /* 52 972 */ /* size: 1024, cachelines: 16, members: 10 */ }; Fixes: 3951e7f050ac ("btrfs: add xxhash64 to checksumming algorithms") Fixes: 3831bf0094ab ("btrfs: add sha256 to checksumming algorithm") CC: stable(a)vger.kernel.org # 5.5+ Signed-off-by: Johannes Thumshirn <johannes.thumshirn(a)wdc.com> --- Changes to v3: * make flags in/out (David) * make csum return opt-in (Hans) Changes to v2: * add additional csum_size (David) * rename flag value to BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE to reflect additional size Changes to v1: * add 'out' comment to be consistent (Hans) * remove le16_to_cpu() (kbuild robot) * switch padding to be all u8 (David) --- fs/btrfs/ioctl.c | 16 +++++++++++++--- include/uapi/linux/btrfs.h | 14 ++++++++++++-- 2 files changed, 25 insertions(+), 5 deletions(-) diff --git a/fs/btrfs/ioctl.c b/fs/btrfs/ioctl.c index b3e4c632d80c..4d70b918f656 100644 --- a/fs/btrfs/ioctl.c +++ b/fs/btrfs/ioctl.c @@ -3198,11 +3198,15 @@ static long btrfs_ioctl_fs_info(struct btrfs_fs_info *fs_info, struct btrfs_ioctl_fs_info_args *fi_args; struct btrfs_device *device; struct btrfs_fs_devices *fs_devices = fs_info->fs_devices; + u32 inflags; int ret = 0; - fi_args = kzalloc(sizeof(*fi_args), GFP_KERNEL); - if (!fi_args) - return -ENOMEM; + fi_args = memdup_user(arg, sizeof(*fi_args)); + if (IS_ERR(fi_args)) + return PTR_ERR(fi_args); + + inflags = fi_args->flags; + fi_args->flags = 0; rcu_read_lock(); fi_args->num_devices = fs_devices->num_devices; @@ -3218,6 +3222,12 @@ static long btrfs_ioctl_fs_info(struct btrfs_fs_info *fs_info, fi_args->sectorsize = fs_info->sectorsize; fi_args->clone_alignment = fs_info->sectorsize; + if (inflags & BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE) { + fi_args->csum_type = btrfs_super_csum_type(fs_info->super_copy); + fi_args->csum_size = btrfs_super_csum_size(fs_info->super_copy); + fi_args->flags |= BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE; + } + if (copy_to_user(arg, fi_args, sizeof(*fi_args))) ret = -EFAULT; diff --git a/include/uapi/linux/btrfs.h b/include/uapi/linux/btrfs.h index e6b6cb0f8bc6..c130eaea416e 100644 --- a/include/uapi/linux/btrfs.h +++ b/include/uapi/linux/btrfs.h @@ -250,10 +250,20 @@ struct btrfs_ioctl_fs_info_args { __u32 nodesize; /* out */ __u32 sectorsize; /* out */ __u32 clone_alignment; /* out */ - __u32 reserved32; - __u64 reserved[122]; /* pad to 1k */ + __u32 flags; /* in/out */ + __u16 csum_type; /* out */ + __u16 csum_size; /* out */ + __u8 reserved[972]; /* pad to 1k */ }; +/* + * fs_info ioctl flags + * + * Used by: + * struct btrfs_ioctl_fs_info_args + */ +#define BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE (1 << 0) + /* * feature flags * -- 2.26.2

[tip: x86/urgent] x86/split_lock: Don't write MSR_TEST_CTRL on CPUs that aren't whitelisted

by tip-bot2 for Sean Christopherson

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 009bce1df0bb5eb970b9eb98d963861f7fe353c7 Gitweb: https://git.kernel.org/tip/009bce1df0bb5eb970b9eb98d963861f7fe353c7 Author: Sean Christopherson <sean.j.christopherson(a)intel.com> AuthorDate: Fri, 05 Jun 2020 12:26:05 -07:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Tue, 30 Jun 2020 14:09:31 +02:00 x86/split_lock: Don't write MSR_TEST_CTRL on CPUs that aren't whitelisted Choo! Choo! All aboard the Split Lock Express, with direct service to Wreckage! Skip split_lock_verify_msr() if the CPU isn't whitelisted as a possible SLD-enabled CPU model to avoid writing MSR_TEST_CTRL. MSR_TEST_CTRL exists, and is writable, on many generations of CPUs. Writing the MSR, even with '0', can result in bizarre, undocumented behavior. This fixes a crash on Haswell when resuming from suspend with a live KVM guest. Because APs use the standard SMP boot flow for resume, they will go through split_lock_init() and the subsequent RDMSR/WRMSR sequence, which runs even when sld_state==sld_off to ensure SLD is disabled. On Haswell (at least, my Haswell), writing MSR_TEST_CTRL with '0' will succeed and _may_ take the SMT _sibling_ out of VMX root mode. When KVM has an active guest, KVM performs VMXON as part of CPU onlining (see kvm_starting_cpu()). Because SMP boot is serialized, the resulting flow is effectively: on_each_ap_cpu() { WRMSR(MSR_TEST_CTRL, 0) VMXON } As a result, the WRMSR can disable VMX on a different CPU that has already done VMXON. This ultimately results in a #UD on VMPTRLD when KVM regains control and attempt run its vCPUs. The above voodoo was confirmed by reworking KVM's VMXON flow to write MSR_TEST_CTRL prior to VMXON, and to serialize the sequence as above. Further verification of the insanity was done by redoing VMXON on all APs after the initial WRMSR->VMXON sequence. The additional VMXON, which should VM-Fail, occasionally succeeded, and also eliminated the unexpected #UD on VMPTRLD. The damage done by writing MSR_TEST_CTRL doesn't appear to be limited to VMX, e.g. after suspend with an active KVM guest, subsequent reboots almost always hang (even when fudging VMXON), a #UD on a random Jcc was observed, suspend/resume stability is qualitatively poor, and so on and so forth. kernel BUG at arch/x86/kvm/x86.c:386!

[PATCH 08/10] mfd: atmel-smc: Silence comparison of unsigned expression < 0 is always false warning (W=1)

by Lee Jones

GENMASK and it's callees conduct checking to ensure the passed parameters are valid. One of those checks is for '< 0'. So if an unsigned value is passed, in an invalid comparison takes place. Judging from the current code, it looks as though 'unsigned int' is the correct type to use, so simply cast these small values with no chance of being false negative to signed int for comparison/error checking purposes.

[PATCH] KVM: x86: bit 8 of non-leaf PDPEs is not reserved

by Paolo Bonzini

Bit 8 would be the "global" bit, which does not quite make sense for non-leaf page table entries. Intel ignores it; AMD ignores it in PDEs and PDPEs, but reserves it in PML4Es. Probably, earlier versions of the AMD manual documented it as reserved in PDPEs as well, and that behavior made it into KVM as well as kvm-unit-tests; fix it.

But these sequences only expand into anything meaningful if the BL_SWITCHER option is selected, which almost never happens. It also turns out that using a RMW and locks is just as silly, as the GIC distributor supports byte accesses for the GICD_TARGETRn registers, which when used make the update atomic by definition. Drop the terminally broken code and replace it by a byte write.

by Johannes Thumshirn

With the recent addition of filesystem checksum types other than CRC32c, it is not anymore hard-coded which checksum type a btrfs filesystem uses. Up to now there is no good way to read the filesystem checksum, apart from reading the filesystem UUID and then query sysfs for the checksum type. Add a new csum_type field to the BTRFS_IOC_FS_INFO ioctl command which usually is used to query filesystem features. Also add a flags member indicating that the kernel responded with a set csum_type field. To simplify further additions to the ioctl, also switch the padding to a u8 array. Pahole was used to verify the result of this switch: pahole -C btrfs_ioctl_fs_info_args fs/btrfs/btrfs.ko struct btrfs_ioctl_fs_info_args { __u64 max_id; /* 0 8 */ __u64 num_devices; /* 8 8 */ __u8 fsid[16]; /* 16 16 */ __u32 nodesize; /* 32 4 */ __u32 sectorsize; /* 36 4 */ __u32 clone_alignment; /* 40 4 */ __u32 flags; /* 44 4 */ __u16 csum_type; /* 48 2 */ __u16 csum_size; /* 50 2 */ __u8 reserved[972]; /* 52 972 */ /* size: 1024, cachelines: 16, members: 10 */ }; Fixes: 3951e7f050ac ("btrfs: add xxhash64 to checksumming algorithms") Fixes: 3831bf0094ab ("btrfs: add sha256 to checksumming algorithm") Cc: stable(a)vger.kernel.org Signed-off-by: Johannes Thumshirn <johannes.thumshirn(a)wdc.com> --- Changes to v2: * add additional csum_size (David) * rename flag value to BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE to reflect additional size Changes to v1: * add 'out' comment to be consistent (Hans) * remove le16_to_cpu() (kbuild robot) * switch padding to be all u8 (David) --- fs/btrfs/ioctl.c | 3 +++ include/uapi/linux/btrfs.h | 14 ++++++++++++-- 2 files changed, 15 insertions(+), 2 deletions(-) diff --git a/fs/btrfs/ioctl.c b/fs/btrfs/ioctl.c index b3e4c632d80c..cfedcdf446c3 100644 --- a/fs/btrfs/ioctl.c +++ b/fs/btrfs/ioctl.c @@ -3217,6 +3217,9 @@ static long btrfs_ioctl_fs_info(struct btrfs_fs_info *fs_info, fi_args->nodesize = fs_info->nodesize; fi_args->sectorsize = fs_info->sectorsize; fi_args->clone_alignment = fs_info->sectorsize; + fi_args->csum_type = btrfs_super_csum_type(fs_info->super_copy); + fi_args->csum_size = btrfs_super_csum_size(fs_info->super_copy); + fi_args->flags |= BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE; if (copy_to_user(arg, fi_args, sizeof(*fi_args))) ret = -EFAULT; diff --git a/include/uapi/linux/btrfs.h b/include/uapi/linux/btrfs.h index e6b6cb0f8bc6..2de3ef3c5c71 100644 --- a/include/uapi/linux/btrfs.h +++ b/include/uapi/linux/btrfs.h @@ -250,10 +250,20 @@ struct btrfs_ioctl_fs_info_args { __u32 nodesize; /* out */ __u32 sectorsize; /* out */ __u32 clone_alignment; /* out */ - __u32 reserved32; - __u64 reserved[122]; /* pad to 1k */ + __u32 flags; /* out */ + __u16 csum_type; /* out */ + __u16 csum_size; /* out */ + __u8 reserved[972]; /* pad to 1k */ }; +/* + * fs_info ioctl flags + * + * Used by: + * struct btrfs_ioctl_fs_info_args + */ +#define BTRFS_FS_INFO_FLAG_CSUM_TYPE_SIZE (1 << 0) + /* * feature flags * -- 2.26.2

External kmod build failed on KASAN-enabled kernel

Hi, The same kmod source code can be built on KASAN-disabled kernel (5.7.0), but after enable it with CONFIG_KASAN=y, the kmod can't build on the new installed KASAN-enabled kernel with below error message, seems no relevant answers for this issue with google: root@build-ws:/home/mm/slab# make make -C /lib/modules/5.7.0/build M=/home/mm/slab modules make[1]: Entering directory '/home/linux-5.7' CC [M] /home/mm/slab/tap_slab.o MODPOST 1 modules ERROR: modpost: "__asan_register_globals" [/home/mm/slab/tap_slab.ko] undefined!

If I'm not > following a proper process for this kind of reports, please let me know. For commits that only have a "Fixes:" tag, and not a "cc: stable..." tag, wait a few weeks, or a month, for us to catch up with them. We usually get to them eventually, but it takes us a while as we have lots more to deal with by developers and maintainers that are properly tagging patches for this type of thing. Some of the above commits are queued up already, but not all of them. I'll take a look at the list after this next round of patches go out, and will let you know. And yes, we do want this type of list, it's greatly appreciated. thanks, greg k-h
