[BACKPORT 4.14.y 0/8] candidates from spreadtrum 4.14 product kernel

I took a scripted approach to look at some product kernels for patches backported into vendor kernels. This is a set of (mostly) bugfixes I found in Spreadtrum's linux-4.14 kernel that are missing in v4.14.107: 83dc7e3dea76 scsi: ufs: fix wrong command type of UTRD for UFSHCI v2.1 099a95f3591a PCI: designware-ep: dw_pcie_ep_set_msi() should only set MMC bits 1cab826b30c6 PCI: designware-ep: Read-only registers need DBI_RO_WR_EN to be writable b330104fa76d PCI: endpoint: Use EPC's device in dma_alloc_coherent()/dma_free_coherent() 36d46cdb43ef rtc: Fix overflow when converting time64_t to rtc_time 1b5d43cfb697 sched/cpufreq/schedutil: Fix error path mutex unlock 5fb5caee92ba pwm-backlight: Enable/disable the PWM before/after LCD enable toggle. f25a646fbe20 power: supply: charger-manager: Fix incorrect return value Only a small number of patches here, the vendor tree is fairly close to mainline.

Cherry-pick two ALSA fixes for stable

by Takashi Iwai

Hi Greg, could you cherry-pick two commits for ALSA fixes to stable tree(s)? The first one is the commit 744c67ffeb06f2d2493f4049ba0bd19698ce0adf ALSA: hda - Don't trigger jackpoll_work in azx_resume and this is only for 5.0.x. The second one is the commit b5a236c175b0d984552a5f7c9d35141024c2b261 ALSA: hda - Enforces runtime_resume after S3 and S4 for each codec which is a fix up to 4.1, but this can be applied cleanly only to recent kernels, supposedly. Both patches contain Fixes tag so that you can judge the kernels to backport. Thanks! Takashi

+ userfaultfd-use-rcu-to-free-the-task-struct-when-fork-fails.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: userfaultfd: use RCU to free the task struct when fork fails has been added to the -mm tree. Its filename is userfaultfd-use-rcu-to-free-the-task-struct-when-fork-fails.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/userfaultfd-use-rcu-to-free-the-ta… and later at http://ozlabs.org/~akpm/mmotm/broken-out/userfaultfd-use-rcu-to-free-the-ta… 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: Andrea Arcangeli <aarcange(a)redhat.com> Subject: userfaultfd: use RCU to free the task struct when fork fails MEMCG depends on the task structure not to be freed under rcu_read_lock() in get_mem_cgroup_from_mm() after it dereferences mm->owner. An alternate possible fix would be to defer the delivery of the userfaultfd contexts to the monitor until after fork() is guaranteed to succeed. Such a change would require more changes because it would create a strict ordering dependency where the uffd methods would need to be called beyond the last potentially failing branch in order to be safe. This solution as opposed only adds the dependency to common code to set mm->owner to NULL and to free the task struct that was pointed by mm->owner with RCU, if fork ends up failing. The userfaultfd methods can still be called anywhere during the fork runtime and the monitor will keep discarding orphaned "mm" coming from failed forks in userland. This race condition couldn't trigger if CONFIG_MEMCG was set =n at build time.

[PATCH] IB/rdmavt: Fix concurrency panics in QP post_send and modify to error

by Michael J. Ruhl

From: Michael J. Ruhl <michael.j.ruhl(a)intel.com> commit d757c60eca9b22f4d108929a24401e0fdecda0b1 upstream The RC/UC code path can go through a software loopback. In this code path the receive side QP is manipulated. If two threads are working on the QP receive side (i.e. post_send, and modify_qp to an error state), QP information can be corrupted. (post_send via loopback) set r_sge loop update r_sge (modify_qp) take r_lock update r_sge <---- r_sge is now incorrect (post_send) update r_sge <---- crash, etc. ... This can lead to one of the two following crashes: BUG: unable to handle kernel NULL pointer dereference at (null) IP: hfi1_copy_sge+0xf1/0x2e0 [hfi1] PGD 8000001fe6a57067 PUD 1fd9e0c067 PMD 0 Call Trace: ruc_loopback+0x49b/0xbc0 [hfi1] hfi1_do_send+0x38e/0x3e0 [hfi1] _hfi1_do_send+0x1e/0x20 [hfi1] process_one_work+0x17f/0x440 worker_thread+0x126/0x3c0 kthread+0xd1/0xe0 ret_from_fork_nospec_begin+0x21/0x21 or: BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 IP: rvt_clear_mr_refs+0x45/0x370 [rdmavt] PGD 80000006ae5eb067 PUD ef15d0067 PMD 0 Call Trace: rvt_error_qp+0xaa/0x240 [rdmavt] rvt_modify_qp+0x47f/0xaa0 [rdmavt] ib_security_modify_qp+0x8f/0x400 [ib_core] ib_modify_qp_with_udata+0x44/0x70 [ib_core] modify_qp.isra.23+0x1eb/0x2b0 [ib_uverbs] ib_uverbs_modify_qp+0xaa/0xf0 [ib_uverbs] ib_uverbs_write+0x272/0x430 [ib_uverbs] vfs_write+0xc0/0x1f0 SyS_write+0x7f/0xf0 system_call_fastpath+0x1c/0x21 Fix by using the appropriate locking on the receiving QP.

This is a note to let you know that I've just added the patch titled staging: erofs: fix error handling when failed to read compresssed 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 b6391ac73400eff38377a4a7364bd3df5efb5178 Mon Sep 17 00:00:00 2001 From: Gao Xiang <gaoxiang25(a)huawei.com> Date: Mon, 25 Mar 2019 11:40:07 +0800 Subject: staging: erofs: fix error handling when failed to read compresssed data Complete read error handling paths for all three kinds of compressed pages: 1) For cache-managed pages, PG_uptodate will be checked since read_endio will unlock and SetPageUptodate for these pages; 2) For inplaced pages, read_endio cannot SetPageUptodate directly since it should be used to mark the final decompressed data, PG_error will be set with page locked for IO error instead; 3) For staging pages, PG_error is used, which is similar to what we do for inplaced pages.

Please backport 25432eba9cd8f2ef (4.15, 4.16, 4.17) ("openvswitch: meter: Fix setting meter id for new entries")

by Yifeng Sun

commit upstream 25432eba9cd8f2ef5afef55be811b010a004b5fa This commit ("openvswitch: meter: Fix setting meter id for new entries") fixes an issue that makes OVS meter malfunction. This fix is already in upstream 4.18 and later. It is a low risk fix, since it only passes the missed value of meter_id to new meter entries. Thanks a lot, Yifeng

[PATCH v4.4.y] mmc: tmio_mmc_core: don't claim spurious interrupts

by Sergei Shtylyov

Commit 5c27ff5db1491a947264d6d4e4cbe43ae6535bae upstream. I have encountered an interrupt storm during the eMMC chip probing (and the chip finally didn't get detected). It turned out that U-Boot left the DMAC interrupts enabled while the Linux driver didn't use those. The SDHI driver's interrupt handler somehow assumes that, even if an SDIO interrupt didn't happen, it should return IRQ_HANDLED. I think that if none of the enabled interrupts happened and got handled, we should return IRQ_NONE -- that way the kernel IRQ code recoginizes a spurious interrupt and masks it off pretty quickly...
