by Greg Kroah-Hartman

This is the start of the stable review cycle for the 5.4.140 release. There are 85 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know. Responses should be made by Thu, 12 Aug 2021 17:29:30 +0000. Anything received after that time might be too late. The whole patch series can be found in one patch at: https://www.kernel.org/pub/linux/kernel/v5.x/stable-review/patch-5.4.140-rc… or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-5.4.y and the diffstat can be found below. thanks, greg k-h ------------- Pseudo-Shortlog of commits: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Linux 5.4.140-rc1 Mark Rutland <mark.rutland(a)arm.com> arm64: fix compat syscall return truncation Letu Ren <fantasquex(a)gmail.com> net/qla3xxx: fix schedule while atomic in ql_wait_for_drvr_lock and ql_adapter_reset Prarit Bhargava <prarit(a)redhat.com> alpha: Send stop IPI to send to online CPUs Matteo Croce <mcroce(a)microsoft.com> virt_wifi: fix error on connect Shreyansh Chouhan <chouhan.shreyansh630(a)gmail.com> reiserfs: check directory items on read from disk Yu Kuai <yukuai3(a)huawei.com> reiserfs: add check for root_inode in reiserfs_fill_super Christoph Hellwig <hch(a)lst.de> libata: fix ata_pio_sector for CONFIG_HIGHMEM Daniel Borkmann <daniel(a)iogearbox.net> bpf, selftests: Adjust few selftest result_unpriv outcomes Like Xu <likexu(a)tencent.com> perf/x86/amd: Don't touch the AMD64_EVENTSEL_HOSTONLY bit inside the guest Arnd Bergmann <arnd(a)arndb.de> soc: ixp4xx/qmgr: fix invalid __iomem access Dongliang Mu <mudongliangabcd(a)gmail.com> spi: meson-spicc: fix memory leak in meson_spicc_remove Arnd Bergmann <arnd(a)arndb.de> soc: ixp4xx: fix printing resources Will Deacon <will(a)kernel.org> arm64: vdso: Avoid ISB after reading from cntvct_el0 Sean Christopherson <seanjc(a)google.com> KVM: x86/mmu: Fix per-cpu counter corruption on 32-bit builds Paolo Bonzini <pbonzini(a)redhat.com> KVM: Do not leak memory for duplicate debugfs directories Paolo Bonzini <pbonzini(a)redhat.com> KVM: x86: accept userspace interrupt only if no event is injected Wei Shuyu <wsy(a)dogben.com> md/raid10: properly indicate failure when ending a failed write request Zheyu Ma <zheyuma97(a)gmail.com> pcmcia: i82092: fix a null pointer dereference bug Thomas Gleixner <tglx(a)linutronix.de> timers: Move clearing of base::timer_running under base:: Lock Mario Kleiner <mario.kleiner.de(a)gmail.com> serial: 8250_pci: Avoid irq sharing for MSI(-X) interrupts.

[PATCH] ACPI: NFIT: Fix support for virtual SPA ranges

by Dan Williams

Fix the NFIT parsing code to treat a 0 index in a SPA Range Structure as a special case and not match Region Mapping Structures that use 0 to indicate that they are not mapped. Without this fix some platform BIOS descriptions of "virtual disk" ranges do not result in the pmem driver attaching to the range. Details: In addition to typical persistent memory ranges, the ACPI NFIT may also convey "virtual" ranges. These ranges are indicated by a UUID in the SPA Range Structure of UUID_VOLATILE_VIRTUAL_DISK, UUID_VOLATILE_VIRTUAL_CD, UUID_PERSISTENT_VIRTUAL_DISK, or UUID_PERSISTENT_VIRTUAL_CD. The critical difference between virtual ranges and UUID_PERSISTENT_MEMORY, is that virtual do not support associations with Region Mapping Structures. For this reason the "index" value of virtual SPA Range Structures is allowed to be 0. If a platform BIOS decides to represent unmapped NVDIMMs with a 0 index in their "SPA Range Structure Index" the driver falsely matches them and may falsely require labels where "virtual disks" are expected to be label-less. I.e. label-less is where the namespace-range == region-range and the pmem driver attaches with no user action to create a namespace.

[PATCH 1/2] btrfs: reduce the preemptive flushing threshold to 90%

by Josef Bacik

The preemptive flushing code was added in order to avoid needing to synchronously wait for ENOSPC flushing to recover space. Once we're almost full however we can essentially flush constantly. We were using 98% as a threshold to determine if we were simply full, however in practice this is a really high bar to hit. For example reports of systems running into this problem had around 94% usage and thus continued to flush. Fix this by lowering the threshold to 90%, which is a more sane value, especially for smaller file systems. cc: stable(a)vger.kernel.org Link: https://bugzilla.kernel.org/show_bug.cgi?id=212185 Fixes: 576fa34830af ("btrfs: improve preemptive background space flushing") Signed-off-by: Josef Bacik <josef(a)toxicpanda.com> --- fs/btrfs/space-info.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/btrfs/space-info.c b/fs/btrfs/space-info.c index d9c8d738678f..ddb4878e94df 100644 --- a/fs/btrfs/space-info.c +++ b/fs/btrfs/space-info.c @@ -733,7 +733,7 @@ static bool need_preemptive_reclaim(struct btrfs_fs_info *fs_info, { u64 global_rsv_size = fs_info->global_block_rsv.reserved; u64 ordered, delalloc; - u64 thresh = div_factor_fine(space_info->total_bytes, 98); + u64 thresh = div_factor(space_info->total_bytes, 9); u64 used; /* If we're just plain full then async reclaim just slows us down. */ -- 2.26.3

[PATCH v3] drm/i915/display: Fix the 12 BPC bits for PIPE_MISC reg

by Ankit Nautiyal

Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the Dithering BPC, with valid values of 6, 8, 10 BPC. For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid values of: 6, 8, 10, 12 BPC, and need to be programmed whether dithering is enabled or not. This patch: -corrects the bits 5-7 for PIPE MISC register for 12 BPC. -renames the bits and mask to have generic names for these bits for dithering bpc and port output bpc. v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout for pipe_bpp. (Uma Shankar) v2: Added 'display' to the subject and fixes tag.

[RESEND PATCH] perf/x86/intel/uncore: Fix invalid unit check

[PATCH v5 2/2] blk-zoned: allow BLKREPORTZONE without CAP_SYS_ADMIN

by Niklas Cassel

From: Niklas Cassel <niklas.cassel(a)wdc.com> A user space process should not need the CAP_SYS_ADMIN capability set in order to perform a BLKREPORTZONE ioctl. Getting the zone report is required in order to get the write pointer. Neither read() nor write() requires CAP_SYS_ADMIN, so it is reasonable that a user space process that can read/write from/to the device, also can get the write pointer. (Since e.g. writes have to be at the write pointer.)

[PATCH v5 1/2] blk-zoned: allow zone management send operations without CAP_SYS_ADMIN

by Niklas Cassel

From: Niklas Cassel <niklas.cassel(a)wdc.com> Zone management send operations (BLKRESETZONE, BLKOPENZONE, BLKCLOSEZONE and BLKFINISHZONE) should be allowed under the same permissions as write(). (write() does not require CAP_SYS_ADMIN). Additionally, other ioctls like BLKSECDISCARD and BLKZEROOUT only check if the fd was successfully opened with FMODE_WRITE. (They do not require CAP_SYS_ADMIN). Currently, zone management send operations require both CAP_SYS_ADMIN and that the fd was successfully opened with FMODE_WRITE. Remove the CAP_SYS_ADMIN requirement, so that zone management send operations match the access control requirement of write(), BLKSECDISCARD and BLKZEROOUT.

[PATCH v2] arm64: clean vdso & vdso32 files

by Andrew Delgadillo

commit a5b8ca97fbf8 ("arm64: do not descend to vdso directories twice") changes the cleaning behavior of arm64's vdso files, in that vdso.lds, vdso.so, and vdso.so.dbg are not removed upon a 'make clean/mrproper': $ make defconfig ARCH=arm64 $ make ARCH=arm64 $ make mrproper ARCH=arm64 $ git clean -nxdf Would remove arch/arm64/kernel/vdso/vdso.lds Would remove arch/arm64/kernel/vdso/vdso.so Would remove arch/arm64/kernel/vdso/vdso.so.dbg To remedy this, manually descend into arch/arm64/kernel/vdso upon cleaning. After this commit: $ make defconfig ARCH=arm64 $ make ARCH=arm64 $ make mrproper ARCH=arm64 $ git clean -nxdf <empty> Similar results are obtained for the vdso32 equivalent.
