[PATCH v2 1/4] 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.

[PATCH] drm/i915/gt: Free stale request on destroying the virtual engine

by Chris Wilson

Since preempt-to-busy, we may unsubmit a request while it is still on the HW and completes asynchronously. That means it may be retired and in the process destroy the virtual engine (as the user has closed their context), but that engine may still be holding onto the unsubmitted compelted request. Therefore we need to potentially cleanup the old request on destroying the virtual engine. We also have to keep the virtual_engine alive until after the sibling's execlists_dequeue() have finished peeking into the virtual engines, for which we serialise with RCU.

[PATCH] drm/i915/gt: Ignore irq enabling on the virtual engines

by Chris Wilson

We do not use the virtual engines for interrupts (they have physical components), but we do use them to decouple the fence signaling during submission. Currently, when we submit a completed request, we try to enable the interrupt handler for the virtual engine, but we never disarm it. A quick fix is then to mark the irq as enabled, and it will then remain enabled -- and this prevents us from waking the device and never letting it sleep again.

[PATCH 1/5] kallsyms: Refactor kallsyms_show_value() to take cred

by Kees Cook

In order to perform future tests against the cred saved during open(), switch kallsyms_show_value() to operate on a cred, and have all current callers pass current_cred(). This makes it very obvious where callers are checking the wrong credential in their "read" contexts. These will be fixed in the coming patches. Additionally switch return value to bool, since it is always used as a direct permission check, not a 0-on-success, negative-on-error style function return.

[to-be-updated] mm-hugetlb-avoid-hardcoding-while-checking-if-cma-is-enable.patch removed from -mm tree

by Andrew Morton

The patch titled Subject: mm/hugetlb: avoid hardcoding while checking if cma is enabled has been removed from the -mm tree. Its filename was mm-hugetlb-avoid-hardcoding-while-checking-if-cma-is-enable.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: Barry Song <song.bao.hua(a)hisilicon.com> Subject: mm/hugetlb: avoid hardcoding while checking if cma is enabled hugetlb_cma[0] can be NULL due to various reasons, for example, node0 has no memory. so NULL hugetlb_cma[0] doesn't necessarily mean cma is not enabled. gigantic pages might have been reserved on other nodes. Mike Kravetz said: : Based on the code changes, I believe the following could happen: : - Someone uses 'hugetlb_cma=' kernel command line parameter to reserve : CMA for gigantic pages. : - The system topology is such that no memory is on node 0. Therefore, : no CMA can be reserved for gigantic pages on node 0. CMA is reserved : on other nodes. : - The user also specifies a number of gigantic pages to pre-allocate on : the command line with hugepagesz=<gigantic_page_size> hugepages=<N> : - The routine which allocates gigantic pages from the bootmem allocator : will not detect CMA has been reserved as there is no memory on node 0. : Therefore, pages will be pre-allocated from bootmem allocator as well : as reserved in CMA. : : This double allocation (bootmem and CMA) is the worst case scenario. Not : sure if this is what Barry saw, and I suspect this would rarely happen.

[PATCH] mm: Close race between munmap() and expand_upwards()/downwards()

by Kirill A. Shutemov

VMA with VM_GROWSDOWN or VM_GROWSUP flag set can change their size under mmap_read_lock(). It can lead to race with __do_munmap(): Thread A Thread B __do_munmap() detach_vmas_to_be_unmapped() mmap_write_downgrade() expand_downwards() vma->vm_start = address; // The VMA now overlaps with // VMAs detached by the Thread A // page fault populates expanded part // of the VMA unmap_region() // Zaps pagetables partly // populated by Thread B Similar race exists for expand_upwards(). The fix is to avoid downgrading mmap_lock in __do_munmap() if detached VMAs are next to VM_GROWSDOWN or VM_GROWSUP VMA. Signed-off-by: Kirill A.

[PATCH v2] ARM: stacktrace: Fix unwind_frame for clang-built kernels

by Nathan Huckleberry

Since clang does not push pc and sp in function prologues, the current implementation of unwind_frame does not work. By using the previous frame's lr/fp instead of saved pc/sp we get valid unwinds on clang-built kernels. The bounds check on next frame pointer must be changed as well since there are 8 less bytes between frames. This fixes /proc/<pid>/stack.

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

by Adam Ford

The drm/omap driver was fixed to correct an issue where using a divider of 32 breaks the DSS despite the TRM stating 32 is a valid number. Through experimentation, it appears that 31 works, and it is consistent with the value used by the drm/omap driver. This patch fixes the divider for fbdev driver instead of the drm. Fixes: f76ee892a99e ("omapfb: copy omapdss & displays for omapfb") Cc: <stable(a)vger.kernel.org> #4.9+ Signed-off-by: Adam Ford <aford173(a)gmail.com> --- Linux 4.4 will need a similar patch, but it doesn't apply cleanly.

Fortunately, no value is recalled from the driver data entry, so it can be easily omitted. Instead we can use the value obtained directly from the platform resource to pass through Regmap into the call-backs to be used for the SMCC call and use a local dedicated __iomem variable for IO-remapping.

[PATCH v3 1/3] mm/shuffle: don't move pages between zones and don't read garbage memmaps

by David Hildenbrand

Especially with memory hotplug, we can have offline sections (with a garbage memmap) and overlapping zones. We have to make sure to only touch initialized memmaps (online sections managed by the buddy) and that the zone matches, to not move pages between zones. To test if this can actually happen, I added a simple BUG_ON(page_zone(page_i) != page_zone(page_j)); right before the swap. When hotplugging a 256M DIMM to a 4G x86-64 VM and onlining the first memory block "online_movable" and the second memory block "online_kernel", it will trigger the BUG, as both zones (NORMAL and MOVABLE) overlap. This might result in all kinds of weird situations (e.g., double allocations, list corruptions, unmovable allocations ending up in the movable zone).

[PATCH 1/6] ASoC: Intel: cht_bsw_rt5672: Change bus format to I2S 2 channel

by Hans de Goede

The default mode for SSP configuration is TDM 4 slot and so far we were using this for the bus format on cht-bsw-rt56732 boards. One board, the Lenovo Miix 2 10 uses not 1 but 2 codecs connected to SSP2. The second piggy-backed, output-only codec is inside the keyboard-dock (which has extra speakers). Unlike the main rt5672 codec, we cannot configure this codec, it is hard coded to use 2 channel 24 bit I2S. Using 4 channel TDM leads to the dock speakers codec (which listens in on the data send from the SSP to the rt5672 codec) emiting horribly distorted sound. Since we only support 2 channels anyways, there is no need for TDM on any cht-bsw-rt5672 designs. So we can simply use I2S 2ch everywhere. This commit fixes the Lenovo Miix 2 10 dock speakers issue by changing the bus format set in cht_codec_fixup() to I2S 2 channel. This change has been tested on the following devices with a rt5672 codec: Lenovo Miix 2 10 Lenovo Thinkpad 8 Lenovo Thinkpad 10 (gen 1) Cc: stable(a)vger.kernel.org BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1786723 Signed-off-by: Hans de Goede <hdegoede(a)redhat.com> --- sound/soc/intel/boards/cht_bsw_rt5672.c | 23 +++++++++++------------ 1 file changed, 11 insertions(+), 12 deletions(-) diff --git a/sound/soc/intel/boards/cht_bsw_rt5672.c b/sound/soc/intel/boards/cht_bsw_rt5672.c index 7a43c70a1378..22e432768edb 100644 --- a/sound/soc/intel/boards/cht_bsw_rt5672.c +++ b/sound/soc/intel/boards/cht_bsw_rt5672.c @@ -253,21 +253,20 @@ static int cht_codec_fixup(struct snd_soc_pcm_runtime *rtd, params_set_format(params, SNDRV_PCM_FORMAT_S24_LE); /* - * Default mode for SSP configuration is TDM 4 slot + * Default mode for SSP configuration is TDM 4 slot.

[PATCH v3] PM / devfreq: rk3399_dmc: Fix kernel oops when rockchip, pmu is absent

by Marc Zyngier

Booting a recent kernel on a rk3399-based system (nanopc-t4), equipped with a recent u-boot and ATF results in an Oops due to a NULL pointer dereference. This turns out to be due to the rk3399-dmc driver looking for an *undocumented* property (rockchip,pmu), and happily using a NULL pointer when the property isn't there. Instead, make most of what was brought in with 9173c5ceb035 ("PM / devfreq: rk3399_dmc: Pass ODT and auto power down parameters to TF-A.") conditioned on finding this property in the device-tree, preventing the driver from exploding.

[PATCH] vmlinux.lds: consider .text.{hot|unlikely}.* part of .text too

by Nick Desaulniers

ld.bfd's internal linker script considers .text.hot AND .text.hot.* to be part of .text, as well as .text.unlikely and .text.unlikely.*. ld.lld will produce .text.hot.*/.text.unlikely.* sections. Make sure to group these together. Otherwise these orphan sections may be placed outside of the the _stext/_etext boundaries.

[PATCH v2 1/4] arm64: Introduce a way to disable the 32bit vdso

by Marc Zyngier

We have a class of errata (grouped under the ARM64_WORKAROUND_1418040 banner) that force the trapping of counter access from 32bit EL0. We would normally disable the whole vdso for such defect, except that it would disable it for 64bit userspace as well, which is a shame. Instead, add a new vdso_clock_mode, which signals that the vdso isn't usable for compat tasks. This gets checked in the new vdso_clocksource_ok() helper, now provided for the 32bit vdso.

[PATCH v2 3/4] arm64: Override SPSR.SS when single-stepping is enabled

by Will Deacon

Luis reports that, when reverse debugging with GDB, single-step does not function as expected on arm64: | I've noticed, under very specific conditions, that a PTRACE_SINGLESTEP | request by GDB won't execute the underlying instruction. As a consequence, | the PC doesn't move, but we return a SIGTRAP just like we would for a | regular successful PTRACE_SINGLESTEP request. The underlying problem is that when the CPU register state is restored as part of a reverse step, the SPSR.SS bit is cleared and so the hardware single-step state can transition to the "active-pending" state, causing an unexpected step exception to be taken immediately if a step operation is attempted. In hindsight, we probably shouldn't have exposed SPSR.SS in the pstate accessible by the GPR regset, but it's a bit late for that now. Instead, simply prevent userspace from configuring the bit to a value which is inconsistent with the TIF_SINGLESTEP state for the task being traced.

[PATCH v2 00/12] ACPI/NVDIMM: Runtime Firmware Activation

by Dan Williams

Changes since v1 [1]: - Move the syscore callback from 'suspend' path to the 'hibernate' path (Rafael) - Add a new PM debug test mode, 'mem-quiet' to disable some unnecessary hibernation steps (memory image preparation) and debug sleeps when the hibernation code is just being used to quiet the system for firmware activation. (Rafael) - Greg already applied "driver-core: Introduce DEVICE_ATTR_ADMIN_{RO,RW}" to driver-core-next, so I'll need to duplicate that commit in nvdimm.git, or work out a common branch baseline with Greg for this topic and driver-core-next to share.

[PATCH v2 2/4] arm64: ptrace: Consistently use pseudo-singlestep exceptions

by Will Deacon

Although the arm64 single-step state machine can be fast-forwarded in cases where we wish to generate a SIGTRAP without actually executing an instruction, this has two major limitations outside of simply skipping an instruction due to emulation. 1. Stepping out of a ptrace signal stop into a signal handler where SIGTRAP is blocked. Fast-forwarding the stepping state machine in this case will result in a forced SIGTRAP, with the handler reset to SIG_DFL. 2. The hardware implicitly fast-forwards the state machine when executing an SVC instruction for issuing a system call. This can interact badly with subsequent ptrace stops signalled during the execution of the system call (e.g. SYSCALL_EXIT or seccomp traps), as they may corrupt the stepping state by updating the PSTATE for the tracee. Resolve both of these issues by injecting a pseudo-singlestep exception on entry to a signal handler and also on return to userspace following a system call.

[PATCH] btrfs: allow use of global block reserve for balance item deletion

by David Sterba

On a filesystem with exhausted metadata, but still enough to start balance, it's possible to hit this error: [324402.053842] BTRFS info (device loop0): 1 enospc errors during balance [324402.060769] BTRFS info (device loop0): balance: ended with status: -28 [324402.172295] BTRFS: error (device loop0) in reset_balance_state:3321: errno=-28 No space left It fails inside reset_balance_state and turns the filesystem to read-only, which is unnecessary and should be fixed too, but the problem is caused by lack for space when the balance item is deleted. This is a one-time operation and from the same rank as unlink that is allowed to use the global block reserve. So do the same for the balance item. Status of the filesystem (100GiB) just after the balance fails: $ btrfs fi df mnt Data, single: total=80.01GiB, used=38.58GiB System, single: total=4.00MiB, used=16.00KiB Metadata, single: total=19.99GiB, used=19.48GiB GlobalReserve, single: total=512.00MiB, used=50.11MiB CC: stable(a)vger.kernel.org # 4.4+ Signed-off-by: David Sterba <dsterba(a)suse.com> --- fs/btrfs/volumes.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/btrfs/volumes.c b/fs/btrfs/volumes.c index f89625de1fff..aabc6c922e04 100644 --- a/fs/btrfs/volumes.c +++ b/fs/btrfs/volumes.c @@ -3231,7 +3231,7 @@ static int del_balance_item(struct btrfs_fs_info *fs_info) if (!path) return -ENOMEM; - trans = btrfs_start_transaction(root, 0); + trans = btrfs_start_transaction_fallback_global_rsv(root, 0); if (IS_ERR(trans)) { btrfs_free_path(path); return PTR_ERR(trans); -- 2.25.0

[PATCH] drm/fb-helper: Fix vt restore

by Daniel Vetter

In the past we had a pile of hacks to orchestrate access between fbdev emulation and native kms clients. We've tried to streamline this, by always preferring the kms side above fbdev calls when a drm master exists, because drm master controls access to the display resources. Unfortunately this breaks existing userspace, specifically Xorg. When exiting Xorg first restores the console to text mode using the KDSET ioctl on the vt. This does nothing, because a drm master is still around. Then it drops the drm master status, which again does nothing, because logind is keeping additional drm fd open to be able to orchestrate vt switches. In the past this is the point where fbdev was restored, as part of the ->lastclose hook on the drm side. Now to fix this regression we don't want to go back to letting fbdev restore things whenever it feels like, or to the pile of hacks we've had before. Instead try and go with a minimal exception to make the KDSET case work again, and nothing else. This means that if userspace does a KDSET call when switching between graphical compositors, there will be some flickering with fbcon showing up for a bit. But a) that's not a regression and b) userspace can fix it by improving the vt switching dance - logind should have all the information it needs. While pondering all this I'm also wondering wheter we should have a SWITCH_MASTER ioctl to allow race-free master status handover. But that's for another day.

[PATCH v5] 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 v4: * zero all data passed in from user-space (I've chosen this variant as I think it is the most complete) 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 ab34179d7cbc..df8a6ba91055 100644 --- a/fs/btrfs/ioctl.c +++ b/fs/btrfs/ioctl.c @@ -3217,11 +3217,15 @@ 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; + memset(fi_args, 0, sizeof(*fi_args)); rcu_read_lock(); fi_args->num_devices = fs_devices->num_devices; @@ -3237,6 +3241,12 @@ 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

[PATCH 2/2] mm/memory_hotplug: fix unpaired mem_hotplug_begin/done

When check_memblock_offlined_cb() returns failed rc(e.g. the memblock is online at that time), mem_hotplug_begin/done is unpaired in such case. Therefore a warning: Call Trace: percpu_up_write+0x33/0x40 try_remove_memory+0x66/0x120 ? _cond_resched+0x19/0x30 remove_memory+0x2b/0x40 dev_dax_kmem_remove+0x36/0x72 [kmem] device_release_driver_internal+0xf0/0x1c0 device_release_driver+0x12/0x20 bus_remove_device+0xe1/0x150 device_del+0x17b/0x3e0 unregister_dev_dax+0x29/0x60 devm_action_release+0x15/0x20 release_nodes+0x19a/0x1e0 devres_release_all+0x3f/0x50 device_release_driver_internal+0x100/0x1c0 driver_detach+0x4c/0x8f bus_remove_driver+0x5c/0xd0 driver_unregister+0x31/0x50 dax_pmem_exit+0x10/0xfe0 [dax_pmem] Fixes: f1037ec0cc8a ("mm/memory_hotplug: fix remove_memory() lockdep splat") Cc: stable(a)vger.kernel.org # v5.6+ Signed-off-by: Jia He <justin.he(a)arm.com> Reviewed-by: David Hildenbrand <david(a)redhat.com> Acked-by: Michal Hocko <mhocko(a)suse.com> Acked-by: Dan Williams <dan.j.williams(a)intel.com> --- mm/memory_hotplug.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/mm/memory_hotplug.c b/mm/memory_hotplug.c index b49ab743d914..3e0645387daf 100644 --- a/mm/memory_hotplug.c +++ b/mm/memory_hotplug.c @@ -1752,7 +1752,7 @@ static int __ref try_remove_memory(int nid, u64 start, u64 size) */ rc = walk_memory_blocks(start, size, NULL, check_memblock_offlined_cb); if (rc) - goto done; + return rc; /* remove memmap entry */ firmware_map_remove(start, start + size, "System RAM"); @@ -1776,9 +1776,8 @@ static int __ref try_remove_memory(int nid, u64 start, u64 size) try_offline_node(nid); -done: mem_hotplug_done(); - return rc; + return 0; } /** -- 2.17.1

It can lead to race with __do_munmap(): Thread A Thread B __do_munmap() detach_vmas_to_be_unmapped() mmap_write_downgrade() expand_downwards() vma->vm_start = address; // The VMA now overlaps with // VMAs detached by the Thread A // page fault populates expanded part // of the VMA unmap_region() // Zaps pagetables partly // populated by Thread B Similar race exists for expand_upwards().

[PATCH AUTOSEL 5.7 01/53] soc: ti: omap-prm: use atomic iopoll instead of sleeping one

by Sasha Levin

From: Tero Kristo <t-kristo(a)ti.com> [ Upstream commit 98ece19f247159a51003796ede7112fef2df5d7f ] The reset handling APIs for omap-prm can be invoked PM runtime which runs in atomic context. For this to work properly, switch to atomic iopoll version instead of the current which can sleep. Otherwise, this throws a "BUG: scheduling while atomic" warning. Issue is seen rather easily when CONFIG_PREEMPT is enabled.

[merged] mm-cmac-use-exact_nid-true-to-fix-possible-per-numa-cma-leak.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/cma.c: use exact_nid true to fix possible per-numa cma leak has been removed from the -mm tree. Its filename was mm-cmac-use-exact_nid-true-to-fix-possible-per-numa-cma-leak.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ 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.

[merged] hugetlb-fix-pages-per-hugetlb-calculation.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/hugetlb.c: fix pages per hugetlb calculation has been removed from the -mm tree. Its filename was hugetlb-fix-pages-per-hugetlb-calculation.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ 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.

"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.

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] 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. Before: # cat /sys/module/*/sections/.*text 0xffffffffc0458000 ... # capsh --drop=CAP_SYSLOG -- -c "cat /sys/module/*/sections/.*text" 0xffffffffc0458000 ... After: # cat /sys/module/*/sections/*.text 0xffffffffc0458000 ... # capsh --drop=CAP_SYSLOG -- -c "cat /sys/module/*/sections/.*text" 0x0000000000000000 ...

[PATCH 2/5] module: Refactor section attr into bin attribute

[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 5/6] drm/ast: Initialize DRAM type before posting GPU

by Thomas Zimmermann

Posting the GPU requires the correct DRAM type to be stored in struct ast_private. Therefore first initialize the DRAM info and then post the GPU. This restores the original order of instructions in this function.

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. The forced alignment of ts isn't strictly necessary in this driver as the padding will be correct anyway (there isn't any). However it is probably less fragile to have it there and it acts as documentation of the requirement.

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.

[PATCH RESEND v2] PCI: Add device even if driver attach failed

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.

[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. Fix this by considering any request not in the MQ_RQ_IDLE state (so either MQ_RQ_COMPLETE or MQ_RQ_IN_FLIGHT) as "inflight" in blk_mq_rq_inflight().

[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.

FAILED: patch "[PATCH] mm, compaction: make capture control handling safe wrt" failed to apply to 5.4-stable tree

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 b9e20f0da1f5c9c68689450a8cb436c9486434c8 Mon Sep 17 00:00:00 2001 From: Vlastimil Babka <vbabka(a)suse.cz> Date: Thu, 25 Jun 2020 20:29:24 -0700 Subject: [PATCH] mm, compaction: make capture control handling safe wrt interrupts Hugh reports: "While stressing compaction, one run oopsed on NULL capc->cc in __free_one_page()'s task_capc(zone): compact_zone_order() had been interrupted, and a page was being freed in the return from interrupt. 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.

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.

[PATCH 07/10] mfd: ab8500-debugfs: Fix incompatible types in comparison expression issue

by Lee Jones

[PATCH 06/10] mfd: ab3100-core: Fix incompatible types in comparison expression warning

by Lee Jones

[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 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). Define a fixed buffer size set to 16 kB. This should be enough for most use with three handles (that is how many we allow at the moment). Parametrize the buffer size while doing this, so that it is easier to revisit this later on if required.

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

by Suzuki K Poulose

The ETM state save/restore incorrectly reads/writes some of the 64bit registers (e.g, address comparators, vmid/cid comparators etc.) using 32bit accesses.

[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. Requesting in stable kernels, since many kernels running in production are stable releases.

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.

Correctly assign the pointer to prevent the following null-pointer-dereference when removing the device: [*] h3ulcb-kf #> echo fea28000.vsp > /sys/bus/platform/devices/fea28000.vsp/driver/unbind Unable to handle kernel NULL pointer dereference at virtual address 0000000000000028 Mem abort info: ESR = 0x96000006 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000006 CM = 0, WnR = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=00000007318be000 [0000000000000028] pgd=00000007333a1003, pud=00000007333a6003, pmd=0000000000000000 Internal error: Oops: 96000006 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 486 Comm: sh Not tainted 5.7.0-rc6-arm64-renesas-00118-ge644645abf47 #185 Hardware name: Renesas H3ULCB Kingfisher board based on r8a77951 (DT) pstate: 40000005 (nZcv daif -PAN -UAO) pc : vsp1_dlm_destroy+0xe4/0x11c lr : vsp1_dlm_destroy+0xc8/0x11c sp : ffff800012963b60 x29: ffff800012963b60 x28: ffff0006f83fc440 x27: 0000000000000000 x26: ffff0006f5e13e80 x25: ffff0006f5e13ed0 x24: ffff0006f5e13ed0 x23: ffff0006f5e13ed0 x22: dead000000000122 x21: ffff0006f5e3a080 x20: ffff0006f5df2938 x19: ffff0006f5df2980 x18: 0000000000000003 x17: 0000000000000000 x16: 0000000000000016 x15: 0000000000000003 x14: 00000000000393c0 x13: ffff800011a5ec18 x12: ffff800011d8d000 x11: ffff0006f83fcc68 x10: ffff800011a53d70 x9 : ffff8000111f3000 x8 : 0000000000000000 x7 : 0000000000210d00 x6 : 0000000000000000 x5 : ffff800010872e60 x4 : 0000000000000004 x3 : 0000000078068000 x2 : ffff800012781000 x1 : 0000000000002c00 x0 : 0000000000000000 Call trace: vsp1_dlm_destroy+0xe4/0x11c vsp1_wpf_destroy+0x10/0x20 vsp1_entity_destroy+0x24/0x4c vsp1_destroy_entities+0x54/0x130 vsp1_remove+0x1c/0x40 platform_drv_remove+0x28/0x50 __device_release_driver+0x178/0x220 device_driver_detach+0x44/0xc0 unbind_store+0xe0/0x104 drv_attr_store+0x20/0x30 sysfs_kf_write+0x48/0x70 kernfs_fop_write+0x148/0x230 __vfs_write+0x18/0x40 vfs_write+0xdc/0x1c4 ksys_write+0x68/0xf0 __arm64_sys_write+0x18/0x20 el0_svc_common.constprop.0+0x70/0x170 do_el0_svc+0x20/0x80 el0_sync_handler+0x134/0x1b0 el0_sync+0x140/0x180 Code: b40000c2 f9403a60 d2800084 a9400663 (f9401400) ---[ end trace 3875369841fb288a ]--- Fixes: f3b98e3c4d2e16 ("media: vsp1: Provide support for extended command pools") Cc: stable(a)vger.kernel.org # v4.19+ Signed-off-by: Eugeniu Rosca <erosca(a)de.adit-jv.com> Reviewed-by: Kieran Bingham <kieran.bingham+renesas(a)ideasonboard.com> Tested-by: Kieran Bingham <kieran.bingham+renesas(a)ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart(a)ideasonboard.com> Signed-off-by: Hans Verkuil <hverkuil-cisco(a)xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei(a)kernel.org> drivers/media/platform/vsp1/vsp1_dl.c | 2 ++ 1 file changed, 2 insertions(+) --- diff --git a/drivers/media/platform/vsp1/vsp1_dl.c b/drivers/media/platform/vsp1/vsp1_dl.c index d7b43037e500..e07b135613eb 100644 --- a/drivers/media/platform/vsp1/vsp1_dl.c +++ b/drivers/media/platform/vsp1/vsp1_dl.c @@ -431,6 +431,8 @@ vsp1_dl_cmd_pool_create(struct vsp1_device *vsp1, enum vsp1_extcmd_type type, if (!pool) return NULL; + pool->vsp1 = vsp1; + spin_lock_init(&pool->lock); INIT_LIST_HEAD(&pool->free);
