That's correct. These were just preparatory patches for a change in the I2C subsystem to properly report OF module aliases [0]. So these will only be relevant once [0] is merged, but that patch will never be backported to a stable kernel. [0]: https://patchwork.kernel.org/patch/10089425/ Best regards, Javier

[PATCH v4] mmc: dw_mmc: Fix the DTO/CTO timeout overflow calculation for 32-bit systems

by Evgeniy Didin

In commit 9d9491a7da2a ("mmc: dw_mmc: Fix the DTO timeout calculation") and commit 4c2357f57dd5 ("mmc: dw_mmc: Fix the CTO timeout calculation") have been made changes which cause multiply overflow for 32-bit systems. The broken timeout calculations leads to unexpected ETIMEDOUT errors and causes stacktrace splat (such as below) during normal data exchange with SD-card. | Running : 4M-check-reassembly-tcp-cmykw2-rotatew2.out -v0 -w1 | - Info: Finished target initialization. | mmcblk0: error -110 transferring data, sector 320544, nr 2048, cmd response | 0x900, card status 0x0 DIV_ROUND_UP_ULL helps to escape usage of __udivdi3() from libgcc and so code gets compiled on all 32-bit platforms as opposed to usage of DIV_ROUND_UP when we may only compile stuff on a very few arches. Lets cast this multiply to u64 type which prevents overflow.

[PATCH 3/3] tpm-dev-common: Reject too short writes

by Jarkko Sakkinen

From: Alexander Steffen <Alexander.Steffen(a)infineon.com> commit ee70bc1e7b63ac8023c9ff9475d8741e397316e7 upstream. tpm_transmit() does not offer an explicit interface to indicate the number of valid bytes in the communication buffer. Instead, it relies on the commandSize field in the TPM header that is encoded within the buffer. Therefore, ensure that a) enough data has been written to the buffer, so that the commandSize field is present and b) the commandSize field does not announce more data than has been written to the buffer. This should have been fixed with CVE-2011-1161 long ago, but apparently a correct version of that patch never made it into the kernel.

[PATCH 2/3] tpm_tis_spi: Use DMA-safe memory for SPI transfers

by Jarkko Sakkinen

From: Alexander Steffen <Alexander.Steffen(a)infineon.com> commit 6b3a13173f23e798e1ba213dd4a2c065a3b8d751 upstream The buffers used as tx_buf/rx_buf in a SPI transfer need to be DMA-safe. This cannot be guaranteed for the buffers passed to tpm_tis_spi_read_bytes and tpm_tis_spi_write_bytes. Therefore, we need to use our own DMA-safe buffer and copy the data to/from it. The buffer needs to be allocated separately, to ensure that it is cacheline-aligned and not shared with other data, so that DMA can work correctly.

[PATCH 1/3] tpm: constify transmit data pointers

[PATCH] ZBOOT: fix stack protector in compressed boot phase

by Huacai Chen

Call __stack_chk_guard_setup() in decompress_kernel() is too late that stack checking always fails for decompress_kernel() itself. So remove __stack_chk_guard_setup() and initialize __stack_chk_guard at where we define it. Original code comes from ARM but also used for MIPS and SH, so fix them together. If without this fix, compressed booting of these archs will fail because stack checking is enabled by default (>=4.16).

rpmsg_create_ept() returns NULL on error and as such qcom_wcnss_open_channel() does the same. Clarify this in the kernel-doc and correct the error checks in btqcomsmd.

Olof's autobuilder has reported the same thing for the 3.18-stable tree but not any others (for every single file in the kernel, not sure if this warning only shows up for all of them, or just one module).

[PATCH AUTOSEL for 4.14 01/84] drm/edid: set ELD connector type in drm_edid_to_eld()

by Sasha Levin

From: Jani Nikula <jani.nikula(a)intel.com> [ Upstream commit 1d1c36650752b7fb81cee515a9bba4131cac4b7c ] Since drm_edid_to_eld() knows the connector type, we can set the type in ELD while at it. Most connectors this gets called on are not DP encoders, and with the HDMI type being 0, this does not change behaviour for non-DP. For i915 having this in place earlier would have saved a considerable amount of debugging that lead to the fix 2d8f63297b9f ("drm/i915: always update ELD connector type after get modes"). I don't see other drivers, even the ones calling drm_edid_to_eld() on DP connectors, setting the connector type in ELD.

[PATCH AUTOSEL for 4.15 001/102] drm/panel: rpi-touchscreen: propagate errors in rpi_touchscreen_i2c_read()

From: Dan Carpenter <dan.carpenter(a)oracle.com> [ Upstream commit 85b4587f8e94143bafb8b6a4003a5187b9a8753d ] There is one caller which checks whether rpi_touchscreen_i2c_read() returns negative error codes.

[PATCH 4.1 0/3] ext4 encryption fixes for 4.1-stable

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Hi Sasha, can you please apply these backports of ext4 encryption fixes to 4.1-stable? They all have equivalent fixes in 4.4-stable. Most important is patch 1 which prevents unprivileged users from using (or abusing) ext4 encryption when it hasn't been enabled on the filesystem by a system administrator. Patch 2 adds a missing permission check (CVE-2016-10318), and patch 3 is a backport that Ted sent out some months ago that seems to have been missed, for a bug in 4.1 that is very similar to the bug in 4.2+ that was assigned CVE-2017-7374. Note that ext4 encryption in 4.1 is still pretty broken and should not be used (even just 4.4-stable is much better); these are just the most important fixes that really ought to be in 4.1-stable. Eric Biggers (1): fscrypto: add authorization check for setting encryption policy Richard Weinberger (1): ext4: require encryption feature for EXT4_IOC_SET_ENCRYPTION_POLICY Theodore Ts'o (1): ext4 crypto: don't regenerate the per-inode encryption key unnecessarily fs/ext4/crypto_fname.c | 5 +++-- fs/ext4/crypto_key.c | 15 ++++++++++++--- fs/ext4/crypto_policy.c | 3 +++ fs/ext4/ext4.h | 1 + fs/ext4/ioctl.c | 3 +++ fs/ext4/super.c | 3 +++ 6 files changed, 25 insertions(+), 5 deletions(-) -- 2.16.2.395.g2e18187dfd-goog

[PATCH] ALSA: hda - Fix a wrong FIXUP for alc289 on Dell machines

by Hui Wang

With the alc289, the Pin 0x1b is Headphone-Mic, so we should assign ALC269_FIXUP_DELL4_MIC_NO_PRESENCE rather than ALC225_FIXUP_DELL1_MIC_NO_PRESENCE to it. And this change is suggested by Kailang of Realtek and is verified on the machine.

[RHEL7.4.z PATCH] md: separate request handling

by Denys Vlasenko

Rediffed for RHEL7.4.z. Conflicts: The return value of md_make_request is different from RHEL to upstream. And RHEL7 MD code does not use bio->bi_opf, but bio->bi_rw. -Nigel Croxon commit 393debc23c7820211d1c8253dd6a8408a7628fe7 Author: Shaohua Li <shli(a)fb.com> Date: Thu Sep 21 10:23:35 2017 -0700 md: separate request handling With commit cc27b0c78c79, pers->make_request could bail out without handling the bio.

[PATCH v5 00/12] vfio, dax: prevent long term filesystem-dax pins and other fixes

by Dan Williams

Changes since v4 [1]: * Fix the changelog of "dax: introduce IS_DEVDAX() and IS_FSDAX()" to better clarify the need for new helpers (Jan) * Replace dax_sem_is_locked() with dax_sem_assert_held() (Jan) * Use file_inode() in vma_is_dax() (Jan) * Resend the full series to linux-xfs@ (Dave) * Collect Jan's Reviewed-by [1]: https://lists.01.org/pipermail/linux-nvdimm/2018-February/014271.html --- The vfio interface, like RDMA, wants to setup long term (indefinite) pins of the pages backing an address range so that a guest or userspace driver can perform DMA to the with physical address. Given that this pinning may lead to filesystem operations deadlocking in the filesystem-dax case, the pinning request needs to be rejected. The longer term fix for vfio, RDMA, and any other long term pin user, is to provide a 'pin with lease' mechanism. Similar to the leases that are hold for pNFS RDMA layouts, this userspace lease gives the kernel a way to notify userspace that the block layout of the file is changing and the kernel is revoking access to pinned pages. Related to this change is the discovery that vma_is_fsdax() was causing device-dax inode detection to fail. That lead to series of fixes and cleanups to make sure that S_DAX is defined correctly in the CONFIG_FS_DAX=n + CONFIG_DEV_DAX=y case. --- Dan Williams (12): dax: fix vma_is_fsdax() helper dax: introduce IS_DEVDAX() and IS_FSDAX() ext2, dax: finish implementing dax_sem helpers ext2, dax: define ext2_dax_*() infrastructure in all cases ext4, dax: define ext4_dax_*() infrastructure in all cases ext2, dax: replace IS_DAX() with IS_FSDAX() ext4, dax: replace IS_DAX() with IS_FSDAX() xfs, dax: replace IS_DAX() with IS_FSDAX() mm, dax: replace IS_DAX() with IS_DEVDAX() or IS_FSDAX() fs, dax: kill IS_DAX() dax: fix S_DAX definition vfio: disable filesystem-dax page pinning drivers/vfio/vfio_iommu_type1.c | 18 ++++++++++++++-- fs/ext2/ext2.h | 6 +++++ fs/ext2/file.c | 19 +++++------------ fs/ext2/inode.c | 10 ++++----- fs/ext4/file.c | 18 +++++----------- fs/ext4/inode.c | 4 ++-- fs/ext4/ioctl.c | 2 +- fs/ext4/super.c | 2 +- fs/iomap.c | 2 +- fs/xfs/xfs_file.c | 14 ++++++------- fs/xfs/xfs_ioctl.c | 4 ++-- fs/xfs/xfs_iomap.c | 6 +++-- fs/xfs/xfs_reflink.c | 2 +- include/linux/dax.h | 12 ++++++++--- include/linux/fs.h | 43 ++++++++++++++++++++++++++++----------- mm/fadvise.c | 3 ++- mm/filemap.c | 4 ++-- mm/huge_memory.c | 4 +++- mm/madvise.c | 3 ++- 19 files changed, 102 insertions(+), 74 deletions(-)

+ mm-page_alloc-fix-memmap_init_zone-pageblock-alignment.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/page_alloc: fix memmap_init_zone pageblock alignment has been added to the -mm tree. Its filename is mm-page_alloc-fix-memmap_init_zone-pageblock-alignment.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-page_alloc-fix-memmap_init_zone… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-page_alloc-fix-memmap_init_zone… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Daniel Vacek <neelx(a)redhat.com> Subject: mm/page_alloc: fix memmap_init_zone pageblock alignment b92df1de5d28 ("mm: page_alloc: skip over regions of invalid pfns where possible") introduced a bug where move_freepages() triggers a VM_BUG_ON() on uninitialized page structure due to pageblock alignment. To fix this, simply align the skipped pfns in memmap_init_zone() the same way as in move_freepages_block(). Seen in one of the RHEL reports: crash> log | grep -e BUG -e RIP -e Call.Trace -e move_freepages_block -e rmqueue -e freelist -A1 kernel BUG at mm/page_alloc.c:1389! invalid opcode: 0000 [#1] SMP -- RIP: 0010:[<ffffffff8118833e>] [<ffffffff8118833e>] move_freepages+0x15e/0x160 RSP: 0018:ffff88054d727688 EFLAGS: 00010087 -- Call Trace: [<ffffffff811883b3>] move_freepages_block+0x73/0x80 [<ffffffff81189e63>] __rmqueue+0x263/0x460 [<ffffffff8118c781>] get_page_from_freelist+0x7e1/0x9e0 [<ffffffff8118caf6>] __alloc_pages_nodemask+0x176/0x420 -- RIP [<ffffffff8118833e>] move_freepages+0x15e/0x160 RSP <ffff88054d727688> crash> page_init_bug -v | grep RAM <struct resource 0xffff88067fffd2f8> 1000 - 9bfff System RAM (620.00 KiB) <struct resource 0xffff88067fffd3a0> 100000 - 430bffff System RAM ( 1.05 GiB = 1071.75 MiB = 1097472.00 KiB) <struct resource 0xffff88067fffd410> 4b0c8000 - 4bf9cfff System RAM ( 14.83 MiB = 15188.00 KiB) <struct resource 0xffff88067fffd480> 4bfac000 - 646b1fff System RAM (391.02 MiB = 400408.00 KiB) <struct resource 0xffff88067fffd560> 7b788000 - 7b7fffff System RAM (480.00 KiB) <struct resource 0xffff88067fffd640> 100000000 - 67fffffff System RAM ( 22.00 GiB) crash> page_init_bug | head -6 <struct resource 0xffff88067fffd560> 7b788000 - 7b7fffff System RAM (480.00 KiB) <struct page 0xffffea0001ede200> 1fffff00000000 0 <struct pglist_data 0xffff88047ffd9000> 1 <struct zone 0xffff88047ffd9800> DMA32 4096 1048575 <struct page 0xffffea0001ede200> 505736 505344 <struct page 0xffffea0001ed8000> 505855 <struct page 0xffffea0001edffc0> <struct page 0xffffea0001ed8000> 0 0 <struct pglist_data 0xffff88047ffd9000> 0 <struct zone 0xffff88047ffd9000> DMA 1 4095 <struct page 0xffffea0001edffc0> 1fffff00000400 0 <struct pglist_data 0xffff88047ffd9000> 1 <struct zone 0xffff88047ffd9800> DMA32 4096 1048575 BUG, zones differ!

Earlier FOLL_NOWAIT was only ever passed to get_user_pages. Specifically faultin_page (the callee of get_user_pages_unlocked caller) doesn't know that if FAULT_FLAG_RETRY_NOWAIT was set in the page fault flags, when VM_FAULT_RETRY is returned, the mmap_sem wasn't actually released (even if nonblocking is not NULL). So it sets *nonblocking to zero and the caller won't release the mmap_sem thinking it was already released, but it wasn't because of FOLL_NOWAIT.

[PATCH] spi: Fix scatterlist elements size in spi_map_buf

by Maxime Chevallier

When SPI transfers can be offloaded using DMA, the SPI core need to build a scatterlist to make sure that the buffer to be transferred is dma-able. This patch fixes the scatterlist entry size computation in the case where the maximum acceptable scatterlist entry supported by the DMA controller is less than PAGE_SIZE, when the buffer is vmalloced. For each entry, the actual size is given by the minimum between the desc_len (which is the max buffer size supported by the DMA controller) and the remaining buffer length until we cross a page boundary.

This really should not happen and blowing up kernel size with checks of impossible situations isn't the way to go. In case you really want to do something here you can add something like ASSERT(xs_state_users) before decrementing the counter. Juergen

Right. I'd prefer this solution. Remains the only problem you tried to tackle with your second patch: a kernel driver going crazy and ending transactions it never started (or ending them multiple times). The EINVAL case can't happen here, but ENOENT can. Either ENOENT has to be handled in xs_request_exit() or you need to keep track of the transactions like in the user interface and refuse ending an unknown transaction. Or you trust the kernel users. Trying to fix the usage counter seems to be the wrong approach IMO. Juergen

It needs platform maintainers to be motivated to fix it, and one way to provide that motivation is for subsystem maintainers to say no to patches like this. If patches like this get accepted, then the "problem" gets solved, and there is very little motivation to fix the platform itself. If you look back at the history of this, the times when platforms have been fixed is when they have a problem exactly like this, and they're told to fix their platforms IRQ numbering instead of the patch to "fix" the driver being accepted. Why fix the interrupt numbering if patches to "fix" drivers get accepted? -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up

[PATCH] i2c: s3c2410: Properly handle interrupts of number 0

by Krzysztof Kozlowski

Interrupt number 0 (returned by platform_get_irq()) might be a valid IRQ so do not treat it as an error. If interrupt 0 was configured, the driver would exit the probe early, before finishing initialization, but with 0-exit status.

[PATCH 1/1] usb: gadget: f_fs: Fix use-after-free in ffs_fs_kill_sb()

by Xinyong

When I debug a kernel crash issue in funcitonfs, found ffs_data.ref overflowed, While functionfs is unmounting, ffs_data is put twice. Commit 43938613c6fd ("drivers, usb: convert ffs_data.ref from atomic_t to refcount_t") can avoid refcount overflow, but that is risk some situations. So no need put ffs data in ffs_fs_kill_sb, already put in ffs_data_closed. The issue can be reproduced in Mediatek mt6763 SoC, ffs for ADB device. KASAN enabled configuration reports use-after-free errro.

Wait, when did we decide that 12 wasn't enough? I just did a `git log | grep Fixes | tee baz | head -n 200` and only on my git tree tehre were only 2 which used exactly 14 digits. The standard is 12. regards, dan carpenter

Both Eric and Paolo noticed the rcu_barrier() we use in tcf_block_put_ext() could be a performance bottleneck when we have a lot of tc classes. Paolo provided the following to demonstrate the issue: tc qdisc add dev lo root htb for I in `seq 1 1000`; do tc class add dev lo parent 1: classid 1:$I htb rate 100kbit tc qdisc add dev lo parent 1:$I handle $((I + 1)): htb for J in `seq 1 10`; do tc filter add dev lo parent $((I + 1)): u32 match ip src 1.1.1.$J done done time tc qdisc del dev root real 0m54.764s user 0m0.023s sys 0m0.000s The rcu_barrier() there is to ensure we free the block after all chains are gone, that is, to queue tcf_block_put_final() at the tail of workqueue. We can achieve this ordering requirement by refcnt'ing tcf block instead, that is, the tcf block is freed only when the last chain in this block is gone. This also simplifies the code.

[Patch 4.14 0/4] net_sched: backport tc filter fixes to 4.14

by Cong Wang

This patchset backports 4 important bug fixes for tc filter to 4.14 stable branch. Due to some big changes between 4.14 and 4.15, the backports are not trivial, I have to adjust and fix the conflicts manually. Thanks to Roland for reporting the kernel warning and testing the patches.

GCC7 is a bit too eager to generate suboptimal __multi3 calls (128bit multiply with 128bit result) for MIPS64r6 builds, even in code which doesn't explicitly use 128bit types, such as the following: unsigned long func(unsigned long a, unsigned long b) { return a > (~0UL) / b; } Which GCC rearanges to: return (unsigned __int128)a * (unsigned __int128)b > 0xffffffffffffffff; Therefore implement __multi3, but only for MIPS64r6 with GCC7 as under normal circumstances we wouldn't expect any calls to __multi3 to be generated from kernel code.

[PATCH] pinctrl: samsung: Validate alias coming from DT

by Krzysztof Kozlowski

Driver uses alias from Device Tree as an index of pin controller data array. In case of a wrong DTB or an out-of-tree DTB, the alias could be outside of this data array leading to out-of-bounds access. Depending on binary and memory layout, this could be handled properly (showing error like "samsung-pinctrl 3860000.pinctrl: driver data not available") or could lead to exceptions. Reported-by: Geert Uytterhoeven <geert(a)linux-m68k.org> Cc: <stable(a)vger.kernel.org> Fixes: 30574f0db1b1 ("pinctrl: add samsung pinctrl and gpiolib driver") Signed-off-by: Krzysztof Kozlowski <krzk(a)kernel.org> --- Issue is present since first version of this driver so this should be backported as far as possible. Tested on Odroid HC1 (Exynos5422). Tests on S3C24xx, S3C64xx, Exynos ARM64 and any other chips are highly appreciated. Linus, I can take it through samsung/pinctrl tree and later send you again as pull request... or you can apply it directly as I do not have any other pinctrl patches queued so far. --- drivers/pinctrl/samsung/pinctrl-exynos-arm.c | 56 +++++++++++++++++++---- drivers/pinctrl/samsung/pinctrl-exynos-arm64.c | 14 +++++- drivers/pinctrl/samsung/pinctrl-s3c24xx.c | 28 ++++++++++-- drivers/pinctrl/samsung/pinctrl-s3c64xx.c | 7 ++- drivers/pinctrl/samsung/pinctrl-samsung.c | 61 ++++++++++++++++---------- drivers/pinctrl/samsung/pinctrl-samsung.h | 40 ++++++++++------- 6 files changed, 154 insertions(+), 52 deletions(-) diff --git a/drivers/pinctrl/samsung/pinctrl-exynos-arm.c b/drivers/pinctrl/samsung/pinctrl-exynos-arm.c index c32399faff57..90c274490181 100644 --- a/drivers/pinctrl/samsung/pinctrl-exynos-arm.c +++ b/drivers/pinctrl/samsung/pinctrl-exynos-arm.c @@ -124,7 +124,7 @@ static const struct samsung_pin_bank_data s5pv210_pin_bank[] __initconst = { EXYNOS_PIN_BANK_EINTW(8, 0xc60, "gph3", 0x0c), }; -const struct samsung_pin_ctrl s5pv210_pin_ctrl[] __initconst = { +static const struct samsung_pin_ctrl s5pv210_pin_ctrl[] __initconst = { { /* pin-controller instance 0 data */ .pin_banks = s5pv210_pin_bank, @@ -137,6 +137,11 @@ const struct samsung_pin_ctrl s5pv210_pin_ctrl[] __initconst = { }, }; +const struct samsung_pinctrl_of_match_data s5pv210_of_data __initconst = { + .ctrl = s5pv210_pin_ctrl, + .num_ctrl = ARRAY_SIZE(s5pv210_pin_ctrl), +}; + /* Pad retention control code for accessing PMU regmap */ static atomic_t exynos_shared_retention_refcnt; @@ -199,7 +204,7 @@ static const struct samsung_retention_data exynos3250_retention_data __initconst * Samsung pinctrl driver data for Exynos3250 SoC.

[PATCH 3/3] IB/srpt: Fix an out-of-bounds stack access in srpt_zerolength_write()

Its filename was vmalloc-fix-__gfp_highmem-usage-for-vmalloc_32-on-32b-systems.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Michal Hocko <mhocko(a)suse.com> Subject: vmalloc: fix __GFP_HIGHMEM usage for vmalloc_32 on 32b systems Kai Heng Feng has noticed that BUG_ON(PageHighMem(pg)) triggers in drivers/media/common/saa7146/saa7146_core.c since 19809c2da28a ("mm, vmalloc: use __GFP_HIGHMEM implicitly"). saa7146_vmalloc_build_pgtable uses vmalloc_32 and it is reasonable to expect that the resulting page is not in highmem. The above commit aimed to add __GFP_HIGHMEM only for those requests which do not specify any zone modifier gfp flag. vmalloc_32 relies on GFP_VMALLOC32 which should do the right thing. Except it has been missed that GFP_VMALLOC32 is an alias for GFP_KERNEL on 32b architectures. Thanks to Matthew to notice this. Fix the problem by unconditionally setting GFP_DMA32 in GFP_VMALLOC32 for !64b arches (as a bailout). This should do the right thing and use ZONE_NORMAL which should be always below 4G on 32b systems. Debugged by Matthew Wilcox.

[merged] mm-swap-frontswap-fix-thp-swap-if-frontswap-enabled-v3.patch removed from -mm tree

Its filename was mm-swap-frontswap-fix-thp-swap-if-frontswap-enabled-v3.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Huang Ying <huang.ying.caritas(a)gmail.com> Subject: mm, swap, frontswap: fix THP swap if frontswap enabled It was reported by Sergey Senozhatsky that if THP (Transparent Huge Page) and frontswap (via zswap) are both enabled, when memory goes low so that swap is triggered, segfault and memory corruption will occur in random user space applications as follow, kernel: urxvt[338]: segfault at 20 ip 00007fc08889ae0d sp 00007ffc73a7fc40 error 6 in libc-2.26.so[7fc08881a000+1ae000] #0 0x00007fc08889ae0d _int_malloc (libc.so.6) #1 0x00007fc08889c2f3 malloc (libc.so.6) #2 0x0000560e6004bff7 _Z14rxvt_wcstoutf8PKwi (urxvt) #3 0x0000560e6005e75c n/a (urxvt) #4 0x0000560e6007d9f1 _ZN16rxvt_perl_interp6invokeEP9rxvt_term9hook_typez (urxvt) #5 0x0000560e6003d988 _ZN9rxvt_term9cmd_parseEv (urxvt) #6 0x0000560e60042804 _ZN9rxvt_term6pty_cbERN2ev2ioEi (urxvt) #7 0x0000560e6005c10f _Z17ev_invoke_pendingv (urxvt) #8 0x0000560e6005cb55 ev_run (urxvt) #9 0x0000560e6003b9b9 main (urxvt) #10 0x00007fc08883af4a __libc_start_main (libc.so.6) #11 0x0000560e6003f9da _start (urxvt) After bisection, it was found the first bad commit is bd4c82c22c367e068 ("mm, THP, swap: delay splitting THP after swapped out"). The root cause is as follows: When the pages are written to swap device during swapping out in swap_writepage(), zswap (fontswap) is tried to compress the pages to improve performance. But zswap (frontswap) will treat THP as a normal page, so only the head page is saved. After swapping in, tail pages will not be restored to their original contents, causing memory corruption in the applications. This is fixed by refusing to save page in the frontswap store functions if the page is a THP. So that the THP will be swapped out to swap device. Another choice is to split THP if frontswap is enabled. But it is found that the frontswap enabling isn't flexible. For example, if CONFIG_ZSWAP=y (cannot be module), frontswap will be enabled even if zswap itself isn't enabled. Frontswap has multiple backends, to make it easy for one backend to enable THP support, the THP checking is put in backend frontswap store functions instead of the general interfaces.

[merged] kbuild-always-define-endianess-in-kconfigh.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: Kbuild: always define endianess in kconfig.h has been removed from the -mm tree. Its filename was kbuild-always-define-endianess-in-kconfigh.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Arnd Bergmann <arnd(a)arndb.de> Subject: Kbuild: always define endianess in kconfig.h Build testing with LTO found a couple of files that get compiled differently depending on whether asm/byteorder.h gets included early enough or not. In particular, include/asm-generic/qrwlock_types.h is affected by this, but there are probably others as well. The symptom is a series of LTO link time warnings, including these: net/netlabel/netlabel_unlabeled.h:223: error: type of 'netlbl_unlhsh_add' does not match original declaration [-Werror=lto-type-mismatch] int netlbl_unlhsh_add(struct net *net, net/netlabel/netlabel_unlabeled.c:377: note: 'netlbl_unlhsh_add' was previously declared here include/net/ipv6.h:360: error: type of 'ipv6_renew_options_kern' does not match original declaration [-Werror=lto-type-mismatch] ipv6_renew_options_kern(struct sock *sk, net/ipv6/exthdrs.c:1162: note: 'ipv6_renew_options_kern' was previously declared here net/core/dev.c:761: note: 'dev_get_by_name_rcu' was previously declared here struct net_device *dev_get_by_name_rcu(struct net *net, const char *name) net/core/dev.c:761: note: code may be misoptimized unless -fno-strict-aliasing is used drivers/gpu/drm/i915/i915_drv.h:3377: error: type of 'i915_gem_object_set_to_wc_domain' does not match original declaration [-Werror=lto-type-mismatch] i915_gem_object_set_to_wc_domain(struct drm_i915_gem_object *obj, bool write); drivers/gpu/drm/i915/i915_gem.c:3639: note: 'i915_gem_object_set_to_wc_domain' was previously declared here include/linux/debugfs.h:92:9: error: type of 'debugfs_attr_read' does not match original declaration [-Werror=lto-type-mismatch] ssize_t debugfs_attr_read(struct file *file, char __user *buf, fs/debugfs/file.c:318: note: 'debugfs_attr_read' was previously declared here include/linux/rwlock_api_smp.h:30: error: type of '_raw_read_unlock' does not match original declaration [-Werror=lto-type-mismatch] void __lockfunc _raw_read_unlock(rwlock_t *lock) __releases(lock); kernel/locking/spinlock.c:246:26: note: '_raw_read_unlock' was previously declared here include/linux/fs.h:3308:5: error: type of 'simple_attr_open' does not match original declaration [-Werror=lto-type-mismatch] int simple_attr_open(struct inode *inode, struct file *file, fs/libfs.c:795: note: 'simple_attr_open' was previously declared here All of the above are caused by include/asm-generic/qrwlock_types.h failing to include asm/byteorder.h after commit e0d02285f16e ("locking/qrwlock: Use 'struct qrwlock' instead of 'struct __qrwlock'") in linux-4.15. Similar bugs may or may not exist in older kernels as well, but there is no easy way to test those with link-time optimizations, and kernels before 4.14 are harder to fix because they don't have Babu's patch series We had similar issues with CONFIG_ symbols in the past and ended up always including the configuration headers though linux/kconfig.h. This works around the issue through that same file, defining either __BIG_ENDIAN or __LITTLE_ENDIAN depending on CONFIG_CPU_BIG_ENDIAN, which is now always set on all architectures since commit 4c97a0c8fee3 ("arch: define CPU_BIG_ENDIAN for all fixed big endian archs").

[PATCH] bcache: decouple emitting a cached_dev CHANGE uevent

by Joseph Salisbury

From: Ryan Harper <ryan.harper(a)canonical.com> BugLink: http://bugs.launchpad.net/bugs/1729145 A bug is preventing /dev/bcache/by-uuid links from being created after reboot. It appears that since the initramfs loads the bcache module which probes and finds all of the cache devices and backing devices then once the rootfs is mounted and udev gets to run, the bcache kernel module does not emit the CACHED_UUID value into the environment if the underlying devices are already registered. With this patch, instead of just failing with "device already registered" the kernel emits another uevent with CACHED_UUID which would be processed another time to set up a symlink. - decouple emitting a cached_dev CHANGE uevent which includes dev.uuid and dev.label from bch_cached_dev_run() which only happens when a bcacheX device is bound to the actual backing block device (bcache0 -> vdb) - update bch_cached_dev_run() to invoke bch_cached_dev_emit_change() as needed; no functional code path changes here - Modify register_bcache to detect a re-registering of a bcache cached_dev, and in that case call bcache_cached_dev_emit_change() to Cc: stable(a)vger.kernel.org Signed-off-by: Ryan Harper <ryan.harper(a)canonical.com> Signed-off-by: Joseph Salisbury <joseph.salisbury(a)canonical.com> --- drivers/md/bcache/bcache.h | 1 + drivers/md/bcache/super.c | 53 +++++++++++++++++++++++++++++++++++++--------- 2 files changed, 44 insertions(+), 10 deletions(-) diff --git a/drivers/md/bcache/bcache.h b/drivers/md/bcache/bcache.h index 02619ca..8ed7e7a 100644 --- a/drivers/md/bcache/bcache.h +++ b/drivers/md/bcache/bcache.h @@ -906,6 +906,7 @@ int bch_flash_dev_create(struct cache_set *c, uint64_t size); int bch_cached_dev_attach(struct cached_dev *, struct cache_set *); void bch_cached_dev_detach(struct cached_dev *); +void bch_cached_dev_emit_change(struct cached_dev *); void bch_cached_dev_run(struct cached_dev *); void bcache_device_stop(struct bcache_device *); diff --git a/drivers/md/bcache/super.c b/drivers/md/bcache/super.c index 04608da..9ff0aac 100644 --- a/drivers/md/bcache/super.c +++ b/drivers/md/bcache/super.c @@ -834,7 +834,7 @@ static void calc_cached_dev_sectors(struct cache_set *c) c->cached_dev_sectors = sectors; } -void bch_cached_dev_run(struct cached_dev *dc) +void bch_cached_dev_emit_change(struct cached_dev *dc) { struct bcache_device *d = &dc->disk; char buf[SB_LABEL_SIZE + 1]; @@ -849,9 +849,18 @@ void bch_cached_dev_run(struct cached_dev *dc) buf[SB_LABEL_SIZE] = '\0'; env[2] = kasprintf(GFP_KERNEL, "CACHED_LABEL=%s", buf); + /* won't show up in the uevent file, use udevadm monitor -e instead + * only class / kset properties are persistent */ + kobject_uevent_env(&disk_to_dev(d->disk)->kobj, KOBJ_CHANGE, env); + kfree(env[1]); + kfree(env[2]); + +} + +void bch_cached_dev_run(struct cached_dev *dc) +{ + struct bcache_device *d = &dc->disk; if (atomic_xchg(&dc->running, 1)) { - kfree(env[1]); - kfree(env[2]); return; } @@ -867,11 +876,9 @@ void bch_cached_dev_run(struct cached_dev *dc) add_disk(d->disk); bd_link_disk_holder(dc->bdev, dc->disk.disk); - /* won't show up in the uevent file, use udevadm monitor -e instead - * only class / kset properties are persistent */ - kobject_uevent_env(&disk_to_dev(d->disk)->kobj, KOBJ_CHANGE, env); - kfree(env[1]); - kfree(env[2]); + + /* emit change event */ + bch_cached_dev_emit_change(dc); if (sysfs_create_link(&d->kobj, &disk_to_dev(d->disk)->kobj, "dev") || sysfs_create_link(&disk_to_dev(d->disk)->kobj, &d->kobj, "bcache")) @@ -1916,6 +1923,21 @@ static bool bch_is_open_backing(struct block_device *bdev) { return false; } +static struct cached_dev *bch_find_cached_dev(struct block_device *bdev) { + struct cache_set *c, *tc; + struct cached_dev *dc, *t; + + list_for_each_entry_safe(c, tc, &bch_cache_sets, list) + list_for_each_entry_safe(dc, t, &c->cached_devs, list) + if (dc->bdev == bdev) + return dc; + list_for_each_entry_safe(dc, t, &uncached_devices, list) + if (dc->bdev == bdev) + return dc; + + return NULL; +} + static bool bch_is_open_cache(struct block_device *bdev) { struct cache_set *c, *tc; struct cache *ca; @@ -1941,6 +1963,7 @@ static ssize_t register_bcache(struct kobject *k, struct kobj_attribute *attr, struct cache_sb *sb = NULL; struct block_device *bdev = NULL; struct page *sb_page = NULL; + struct cached_dev *dc = NULL; if (!try_module_get(THIS_MODULE)) return -EBUSY; @@ -1957,10 +1980,20 @@ static ssize_t register_bcache(struct kobject *k, struct kobj_attribute *attr, if (bdev == ERR_PTR(-EBUSY)) { bdev = lookup_bdev(strim(path), 0); mutex_lock(&bch_register_lock); - if (!IS_ERR(bdev) && bch_is_open(bdev)) + if (!IS_ERR(bdev) && bch_is_open(bdev)) { err = "device already registered"; - else + /* emit CHANGE event for backing devices to export + * CACHED_{UUID/LABEL} values to udev */ + if (bch_is_open_backing(bdev)) { + dc = bch_find_cached_dev(bdev); + if (dc) { + bch_cached_dev_emit_change(dc); + err = "device already registered (emitting change event)"; + } + } + } else { err = "device busy"; + } mutex_unlock(&bch_register_lock); if (!IS_ERR(bdev)) bdput(bdev); -- 2.7.4

[PATCH] drm/i915/perf: fix perf stream opening lock

by Lionel Landwerlin

We're seeing on CI that some contexts don't have the programmed OA period timer that directs the OA unit on how often to write reports. The issue is that we're not holding the drm lock from when we edit the context images down to when we set the exclusive_stream variable. This leaves a window for the deferred context allocation to call i915_oa_init_reg_state() that will not program the expected OA timer value, because we haven't set the exclusive_stream yet.

Thus, the patch adds the extra condition for fixing up the weird case to let PWM4 or PWM5 able to work on MT7623. v1 -> v2: use pwm45_fixup naming instead of pwm45_quirk v2 -> v3: add more tags for Reviewed-by, Fixes, and Cc stable Cc: stable(a)vger.kernel.org Fixes: caf065f8fd58 ("pwm: Add MediaTek PWM support") Signed-off-by: Sean Wang <sean.wang(a)mediatek.com> Reviewed-by: Matthias Brugger <matthias.bgg(a)gmail.com> Cc: Zhi Mao <zhi.mao(a)mediatek.com> Cc: John Crispin <john(a)phrozen.org> Cc: Matthias Brugger <matthias.bgg(a)gmail.com> --- drivers/pwm/pwm-mediatek.c | 24 +++++++++++++++++++++--- 1 file changed, 21 insertions(+), 3 deletions(-) diff --git a/drivers/pwm/pwm-mediatek.c b/drivers/pwm/pwm-mediatek.c index f5d97e0..796baea 100644 --- a/drivers/pwm/pwm-mediatek.c +++ b/drivers/pwm/pwm-mediatek.c @@ -29,7 +29,9 @@ #define PWMGDUR 0x0c #define PWMWAVENUM 0x28 #define PWMDWIDTH 0x2c +#define PWM45DWIDTH_FIXUP 0x30 #define PWMTHRES 0x30 +#define PWM45THRES_FIXUP 0x34 #define PWM_CLK_DIV_MAX 7 @@ -54,6 +56,7 @@ static const char * const mtk_pwm_clk_name[MTK_CLK_MAX] = { struct mtk_pwm_platform_data { unsigned int num_pwms; + bool pwm45_fixup; }; /** @@ -66,6 +69,7 @@ struct mtk_pwm_chip { struct pwm_chip chip; void __iomem *regs; struct clk *clks[MTK_CLK_MAX]; + const struct mtk_pwm_platform_data *soc; }; static const unsigned int mtk_pwm_reg_offset[] = { @@ -131,7 +135,8 @@ static int mtk_pwm_config(struct pwm_chip *chip, struct pwm_device *pwm, { struct mtk_pwm_chip *pc = to_mtk_pwm_chip(chip); struct clk *clk = pc->clks[MTK_CLK_PWM1 + pwm->hwpwm]; - u32 resolution, clkdiv = 0; + u32 resolution, clkdiv = 0, reg_width = PWMDWIDTH, + reg_thres = PWMTHRES; int ret; ret = mtk_pwm_clk_enable(chip, pwm); @@ -151,9 +156,18 @@ static int mtk_pwm_config(struct pwm_chip *chip, struct pwm_device *pwm, return -EINVAL; } + if (pc->soc->pwm45_fixup && pwm->hwpwm > 2) { + /* + * PWM[4,5] has distinct offset for PWMDWIDTH and PWMTHRES + * from the other PWMs on MT7623. + */ + reg_width = PWM45DWIDTH_FIXUP; + reg_thres = PWM45THRES_FIXUP; + } + mtk_pwm_writel(pc, pwm->hwpwm, PWMCON, BIT(15) | clkdiv); - mtk_pwm_writel(pc, pwm->hwpwm, PWMDWIDTH, period_ns / resolution); - mtk_pwm_writel(pc, pwm->hwpwm, PWMTHRES, duty_ns / resolution); + mtk_pwm_writel(pc, pwm->hwpwm, reg_width, period_ns / resolution); + mtk_pwm_writel(pc, pwm->hwpwm, reg_thres, duty_ns / resolution); mtk_pwm_clk_disable(chip, pwm); @@ -211,6 +225,7 @@ static int mtk_pwm_probe(struct platform_device *pdev) data = of_device_get_match_data(&pdev->dev); if (data == NULL) return -EINVAL; + pc->soc = data; res = platform_get_resource(pdev, IORESOURCE_MEM, 0); pc->regs = devm_ioremap_resource(&pdev->dev, res); @@ -251,14 +266,17 @@ static int mtk_pwm_remove(struct platform_device *pdev) static const struct mtk_pwm_platform_data mt2712_pwm_data = { .num_pwms = 8, + .pwm45_fixup = false, }; static const struct mtk_pwm_platform_data mt7622_pwm_data = { .num_pwms = 6, + .pwm45_fixup = false, }; static const struct mtk_pwm_platform_data mt7623_pwm_data = { .num_pwms = 5, + .pwm45_fixup = true, }; static const struct of_device_id mtk_pwm_of_match[] = { -- 2.7.4

[PATCH] Bluetooth: btusb: Remove Yoga 920 from the btusb_needs_reset_resume_table

by Hans de Goede

Commit 55a9c95d70ab ("Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking"), added the Lenovo Yoga 920 to the btusb_needs_reset_resume_table. Testing has shown that this is a false positive and the problems where caused by issues with the initial fix: commit fd865802c66b ("Bluetooth: btusb: fix QCA Rome suspend/resume"), which has already been reverted. So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at all and this commit removes it from the btusb_needs_reset_resume_table. Note that after this commit the btusb_needs_reset_resume_table is now empty. It is kept around on purpose, since this whole series of commits started for a reason and there are actually broken platforms around, which need to be added to it.

[PATCH 01/99] ZBOOT: fix stack protector in compressed boot phase

by Huacai Chen

Call __stack_chk_guard_setup() in decompress_kernel() is too late that stack checking always fails for decompress_kernel() itself. So remove __stack_chk_guard_setup() and initialize __stack_chk_guard at where we define it. Original code comes from ARM but also used for MIPS and SH, so fix them together.

[PATCH 0/2 v3] mmc: dw_mmc: Fix DTO/STO timeout overflow calculation

by Evgeniy Didin

For some 32-bit architectures calculation of DTO and STO timeout can be incorrect due to multiply overflow. Lets prevent this by casting multiply and result to u64. Suggested by Jisheng Zhang. Switch DIV_ROUND_UP macro to DIV_ROUND_UP_ULL is not reasonable because overflow happens on multiply and DIV_ROUND_UP_ULL helps with sum overflow. --- Changes since v2: -add fix for cto_ms Evgeniy Didin (2): mmc: dw_mmc: Fix the DTO timeout overflow calculation for 32-bit systems mmc: dw_mmc: Fix the CTO overflow calculation for 32-bit systems drivers/mmc/host/dw_mmc.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) -- 2.11.0

[PATCH] KVM: arm/arm64: Fix check for hugepage size when allocating at Stage 2

by Punit Agrawal

Commit 45ee9d5e97a4 ("KVM: arm/arm64: Check pagesize when allocating a hugepage at Stage 2") lost the check for PMD_SIZE during the backport to 4.9. Fix this by correcting the condition to detect hugepages during stage 2 allocation.

The easiest one is with DNAT, but an even worse one is where UDP encapsulation is used in which case you just have to insert an UDP encapsulation header in between each level of recursion. This patch avoids this problem by reinjecting tranport-mode packets through a tasklet.

Before that commit, /proc/<pid>/stack reported the last execution path of the zombie before it died: [<ffffffff8105b877>] do_exit+0x6f7/0xa80 [<ffffffff8105bc79>] do_group_exit+0x39/0xa0 [<ffffffff8105bcf0>] __wake_up_parent+0x0/0x30 [<ffffffff8152dd09>] system_call_fastpath+0x16/0x1b [<00007fd128f9c4f9>] 0x7fd128f9c4f9 [<ffffffffffffffff>] 0xffffffffffffffff After the commit, it just reports an empty stack trace. The new behavior is actually probably more correct. If the stack refcount has gone down to zero, then the task has already gone through do_exit() and isn't going to run anymore. The stack could be freed at any time and is basically gone, so reporting an empty stack makes sense. However, save_stack_trace_tsk_reliable() treats such a missing stack condition as an error. That can cause livepatch transition stalls if there are any unreaped zombies. Instead, just treat it as a reliable, empty stack.

The compiler doesn't notice this due to an explicit type cast that loses the const - which fragility will be fixed separately. This type cast turned a seemingly trivial const propagation patch into a hard to debug data corruptor and crasher bug.

I believe it worked when the param was introduced but probably later some other changes caused the wrong order and nobody noticed it.

The problem can be reproduced when reducing the vxlan lower dev's pmtu when running netperf. In jianlin's testing, the performance went to 1/7 of the previous. This patch is to update the upper dst pmtu to match the lower dst pmtu on tx path so that packets can be sent out even when lower dev's pmtu has been changed. It also works for metadata dst.

Patch "uapi libc compat: add fallback for unsupported libcs" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled uapi libc compat: add fallback for unsupported libcs to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: uapi-libc-compat-add-fallback-for-unsupported-libcs.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Feb 28 16:23:28 CET 2018 From: Felix Janda <felix.janda(a)posteo.de> Date: Mon, 1 Jan 2018 19:33:20 +0100 Subject: uapi libc compat: add fallback for unsupported libcs From: Felix Janda <felix.janda(a)posteo.de> [ Upstream commit c0bace798436bca0fdc221ff61143f1376a9c3de ] libc-compat.h aims to prevent symbol collisions between uapi and libc headers for each supported libc. This requires continuous coordination between them. The goal of this commit is to improve the situation for libcs (such as musl) which are not yet supported and/or do not wish to be explicitly supported, while not affecting supported libcs. More precisely, with this commit, unsupported libcs can request the suppression of any specific uapi definition by defining the correspondings _UAPI_DEF_* macro as 0. This can fix symbol collisions for them, as long as the libc headers are included before the uapi headers. Inclusion in the other order is outside the scope of this commit. All infrastructure in order to enable this fallback for unsupported libcs is already in place, except that libc-compat.h unconditionally defines all _UAPI_DEF_* macros to 1 for all unsupported libcs so that any previous definitions are ignored. In order to fix this, this commit merely makes these definitions conditional. This commit together with the musl libc commit http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964f… fixes for example the following compiler errors when <linux/in6.h> is included after musl's <netinet/in.h>: ./linux/in6.h:32:8: error: redefinition of 'struct in6_addr' ./linux/in6.h:49:8: error: redefinition of 'struct sockaddr_in6' ./linux/in6.h:59:8: error: redefinition of 'struct ipv6_mreq' The comments referencing glibc are still correct, but this file is not only used for glibc any more.

Patch "staging: ion: Fix ion_cma_heap allocations" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled staging: ion: Fix ion_cma_heap allocations to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: staging-ion-fix-ion_cma_heap-allocations.patch and it can be found in the queue-4.14 subdirectory.

It seems back with 204f672255c2 ("ion: Use CMA APIs directly"), the ion_cma_heap code was modified to use the CMA API, but kept the arguments as buffer lengths rather then number of pages. This results in errors as we don't have enough pages in CMA to satisfy the exaggerated requests. This patch converts the ion_cma_heap CMA API usage to properly request pages. It also fixes a minor issue in the allocation where in the error path, the cma_release is called with the buffer->size value which hasn't yet been set.

That is because some of them called memdup_user() without a ceiling on optlen, allowing it to try to allocate really large buffers. This patch adds a ceiling by limiting optlen to the maximum allowed that would still make sense for these sockopt.

The interrupt may also be masked if previous driver which used the device was malfunctioning and we didn't load the FW (there is no other good way to comprehensively reset the PF).

When there are bitflips, we have to set these bits again to show the upper layers a completely erased page. When a bitflip happens in the exact byte where the bad block marker is, then this byte is swapped with another byte in block_mark_swapping(). The correction code then detects a bitflip in another subpage and no longer corrects the bitflip where it really happens. Correct this behaviour by calling block_mark_swapping() after the bitflips have been corrected. In our case UBIFS failed with this bug because it expects erased pages to be really empty: UBIFS error (pid 187): ubifs_scan: corrupt empty space at LEB 36:118735 UBIFS error (pid 187): ubifs_scanned_corruption: corruption at LEB 36:118735 UBIFS error (pid 187): ubifs_scanned_corruption: first 8192 bytes from LEB 36:118735 UBIFS error (pid 187): ubifs_scan: LEB 36 scanning failed UBIFS error (pid 187): do_commit: commit failed, error -117 Signed-off-by: Sascha Hauer <s.hauer(a)pengutronix.de> Reviewed-by: Richard Weinberger <richard(a)nod.at> Acked-by: Boris Brezillon <boris.brezillon(a)free-electrons.com> Signed-off-by: Richard Weinberger <richard(a)nod.at> Signed-off-by: Sasha Levin <alexander.levin(a)verizon.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/mtd/nand/gpmi-nand/gpmi-nand.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) --- a/drivers/mtd/nand/gpmi-nand/gpmi-nand.c +++ b/drivers/mtd/nand/gpmi-nand/gpmi-nand.c @@ -1067,9 +1067,6 @@ static int gpmi_ecc_read_page(struct mtd return ret; } - /* handle the block mark swapping */ - block_mark_swapping(this, payload_virt, auxiliary_virt); - /* Loop over status bytes, accumulating ECC status. */ status = auxiliary_virt + nfc_geo->auxiliary_status_offset; @@ -1158,6 +1155,9 @@ static int gpmi_ecc_read_page(struct mtd max_bitflips = max_t(unsigned int, max_bitflips, *status); } + /* handle the block mark swapping */ + block_mark_swapping(this, buf, auxiliary_virt); + if (oob_required) { /* * It's time to deliver the OOB bytes.

Patch "lib/mpi: Fix umul_ppmm() for MIPS64r6" has been added to the 4.14-stable tree

Instead it widens the 64-bit inputs to 128-bits and emits a __multi3 intrinsic call to perform a 128 x 128 multiply. This is both inefficient, and it results in a link error since we don't include __multi3 in MIPS linux. For example commit 90a53e4432b1 ("cfg80211: implement regdb signature checking") merged in v4.15-rc1 recently broke the 64r6_defconfig and 64r6el_defconfig builds by indirectly selecting MPILIB. The same build errors can be reproduced on older kernels by enabling e.g. CRYPTO_RSA: lib/mpi/generic_mpih-mul1.o: In function `mpihelp_mul_1': lib/mpi/generic_mpih-mul1.c:50: undefined reference to `__multi3' lib/mpi/generic_mpih-mul2.o: In function `mpihelp_addmul_1': lib/mpi/generic_mpih-mul2.c:49: undefined reference to `__multi3' lib/mpi/generic_mpih-mul3.o: In function `mpihelp_submul_1': lib/mpi/generic_mpih-mul3.c:49: undefined reference to `__multi3' lib/mpi/mpih-div.o In function `mpihelp_divrem': lib/mpi/mpih-div.c:205: undefined reference to `__multi3' lib/mpi/mpih-div.c:142: undefined reference to `__multi3' Therefore add an efficient MIPS64r6 implementation of umul_ppmm() using inline assembly and the DMULU/DMUHU instructions, to prevent __multi3 calls being emitted.

Cleansing of the latter ones wasn't required to fix the original issue but wasn't considered harmful. It nonetheless turned out to be so in case when pointer to one or both props is passed to led_blink_set() like in the ledtrig-timer.c. In such cases zeroes are passed later in delay_on and/or delay_off arguments to led_blink_setup(), which results either in stopping the software blinking or setting blinking frequency always to 1Hz.

If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Feb 28 16:23:28 CET 2018 From: Xin Long <lucien.xin(a)gmail.com> Date: Mon, 18 Dec 2017 14:26:21 +0800 Subject: ip6_tunnel: get the min mtu properly in ip6_tnl_xmit From: Xin Long <lucien.xin(a)gmail.com> [ Upstream commit c9fefa08190fc879fb2e681035d7774e0a8c5170 ] Now it's using IPV6_MIN_MTU as the min mtu in ip6_tnl_xmit, but IPV6_MIN_MTU actually only works when the inner packet is ipv6. With IPV6_MIN_MTU for ipv4 packets, the new pmtu for inner dst couldn't be set less than 1280. It would cause tx_err and the packet to be dropped when the outer dst pmtu is close to 1280. Jianlin found it by running ipv4 traffic with the topo: (client) gre6 <---> eth1 (route) eth2 <---> gre6 (server) After changing eth2 mtu to 1300, the performance became very low, or the connection was even broken. The issue also affects ip4ip6 and ip6ip6 tunnels. So if the inner packet is ipv4, 576 should be considered as the min mtu. Note that for ip4ip6 and ip6ip6 tunnels, the inner packet can only be ipv4 or ipv6, but for gre6 tunnel, it may also be ARP. This patch using 576 as the min mtu for non-ipv6 packet works for all those cases.

It works for ipip6 tunnel. But ip6gre dev updates the mtu also with ip6_tnl_change_mtu. Since the inner packet over ip6gre can be ipv4 and it's mtu should also be allowed to set below 1280, the same issue also exists on ip6gre. This patch is to fix it by simply changing to check if parms.proto is IPPROTO_IPV6 in ip6_tnl_change_mtu instead, to make ip6gre to go to 'else' branch.

Patch "i40e/i40evf: Account for frags split over multiple descriptors in check linearize" has been added to the 4.14-stable tree

As a result we can get into situations where we didn't catch requests that could result in a Tx hang. This patch takes care of that by subtracting the length of all but the trailing edge of the stale fragment before we test for sum. By doing this we can guarantee that we have all cases covered, including the case of a fragment that spans multiple descriptors. We don't need to worry about checking the inner portions of this since 12K is the maximum aligned DMA size and that is larger than any MSS will ever be since the MTU limit for jumbos is something on the order of 9K.

Patch "i40e: don't remove netdev->dev_addr when syncing uc list" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled i40e: don't remove netdev->dev_addr when syncing uc list to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: i40e-don-t-remove-netdev-dev_addr-when-syncing-uc-list.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Feb 28 16:23:28 CET 2018 From: Jacob Keller <jacob.e.keller(a)intel.com> Date: Wed, 20 Dec 2017 11:04:36 -0500 Subject: i40e: don't remove netdev->dev_addr when syncing uc list From: Jacob Keller <jacob.e.keller(a)intel.com> [ Upstream commit 458867b2ca0c987445c5d9adccd1642970e1ba07 ] In some circumstances, such as with bridging, it is possible that the stack will add a devices own MAC address to its unicast address list. If, later, the stack deletes this address, then the i40e driver will receive a request to remove this address. The driver stores its current MAC address as part of the MAC/VLAN hash array, since it is convenient and matches exactly how the hardware expects to be told which traffic to receive. This causes a problem, since for more devices, the MAC address is stored separately, and requests to delete a unicast address should not have the ability to remove the filter for the MAC address. Fix this by forcing a check on every address sync to ensure we do not remove the device address. There is a very narrow possibility of a race between .set_mac and .set_rx_mode, if we don't change netdev->dev_addr before updating our internal MAC list in .set_mac. This might be possible if .set_rx_mode is going to remove MAC "XYZ" from the list, at the same time as .set_mac changes our dev_addr to MAC "XYZ", we might possibly queue a delete, then an add in .set_mac, then queue a delete in .set_rx_mode's dev_uc_sync and then update netdev->dev_addr. We can avoid this by moving the copy into dev_addr prior to the changes to the MAC filter list. A similar race on the other side does not cause problems, as if we're changing our MAC form A to B, and we race with .set_rx_mode, it could queue a delete from A, we'd update our address, and allow the delete. This seems like a race, but in reality we're about to queue a delete of A anyways, so it would not cause any issues. A race in the initialization code is unlikely because the netdevice has not yet been fully initialized and the stack should not be adding or removing addresses yet. Note that we don't (yet) need similar code for the VF driver because it does not make use of __dev_uc_sync and __dev_mc_sync, but instead roles its own method for handling updates to the MAC/VLAN list, which already has code to protect against removal of the hardware address.

This is wrong as under high load other requests can already be queued and overriding the context helpers will make them execute the wrong .send and .handle_result functions. This commit fixes this by adding a needs_inv flag in the request to choose the action to perform when sending requests or handling their results.

Concretely it allocates the bio in __alloc_device and then re-uses it multiple times with a very simple endio routine that just calls complete() without consuming a reference. Allocated bios by default come with a ref count of 1, which is then consumed by the endio routine (or not, in which case they should be bio_put by the caller). The way the impleementation works now is that the flush bio has a refcount of 2 and we only ever bio_put it once, leaving it to hang indefinitely. Fix this by removing the extra bio_get in __alloc_device.

Currently, the check is done against max_vfs. However, the user doesn't always create max_vfs. So, the check should be against the created number of VFs. The number of bnxt_vf_info structures that are allocated in bnxt_alloc_vf_resources routine is the "number of requested VFs". So, if an "invalid VF id" falls between the requested number of VFs and the max_vfs, the driver will be dereferencing an invalid pointer.

Piccoli" <gpiccoli(a)linux.vnet.ibm.com> [ Upstream commit f7084059a9cb9e56a186e1677b1dcffd76c2cd24 ] While in recovery process of PCI error (called EEH on PowerPC arch), another PCI transaction could be corrupted causing a situation of nested PCI errors. Also, this scenario could be reproduced with error injection mechanisms (for debug purposes). We observe that in case of nested PCI errors, bnx2x might attempt to initialize its shmem and cause a kernel crash due to bad addresses read from MCP. Multiple different stack traces were observed depending on the point the second PCI error happens. This patch avoids the crashes by: * failing PCI recovery in case of nested errors (since multiple PCI errors in a row are not expected to lead to a functional adapter anyway), and by, * preventing access to adapter FW when MCP is failed (we mark it as failed when shmem cannot get initialized properly).

Steps to reproduce: - start AVB TX stream (Using aplay via MSE), - disconnect+reconnect the eth cable, - after a reconnection the eth connection goes iteratively up/down without user interaction, - this may heal after some seconds or even stay for minutes. As the documentation specifies, the "renesas,no-ether-link" option should be used when a board does not provide a proper AVB_LINK signal. There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS and ULCB starter kits since the AVB_LINK is correctly handled by HW. Choosing to keep or remove the "renesas,no-ether-link" option will have impact on the code flow in the following ways: - keeping this option enabled may lead to unexpected behavior since the RX & TX are enabled/disabled directly from adjust_link function without any HW interrogation, - removing this option, the RX & TX will only be enabled/disabled after HW interrogation. The HW check is made through the LMON pin in PSR register which specifies AVB_LINK signal value (0 - at low level; 1 - at high level). In conclusion, the present change is also a safety improvement because it removes the "renesas,no-ether-link" option leading to a proper way of detecting the link state based on HW interrogation and not on software heuristic.
