[PATCH 1/6] dm: use bio_split() when splitting out the already processed bio

by Christoph Hellwig

From: Mike Snitzer <snitzer(a)redhat.com> Use of bio_clone_bioset() is inefficient if there is no need to clone the original bio's bio_vec array. Best to use the bio_clone_fast() variant. Also, just using bio_advance() is only part of what is needed to properly setup the clone -- it doesn't account for the various bio_integrity() related work that also needs to be performed (see bio_split). Address both of these issues by switching from bio_clone_bioset() to bio_split().

[PATCH] scsi: scsi_debug: Fix memory leak on module unload

by Luis Henriques

Since commit 80c49563e250 ("scsi: scsi_debug: implement IMMED bit") there are long delays in F_SYNC_DELAY and F_SSU_DELAY. This can cause a memory leak in schedule_resp(), which can be invoked while unloading the scsi_debug module: free_all_queued() had already freed all sd_dp and schedule_resp will alloc a new one, which will never get freed. Here's the kmemleak report while running xfstests generic/350: unreferenced object 0xffff88007d752b00 (size 128): comm "rmmod", pid 26940, jiffies 4295816945 (age 7.588s) hex dump (first 32 bytes): 00 2b 75 7d 00 88 ff ff 00 00 00 00 00 00 00 00 .+u}............ 00 00 00 00 00 00 00 00 8e 31 a2 34 5f 03 00 00 .........1.4_... backtrace: [<000000002abd83d0>] 0xffffffffa000705e [<000000004c063fda>] scsi_dispatch_cmd+0xc7/0x1a0 [<000000000c119a00>] scsi_request_fn+0x251/0x550 [<000000009de0c736>] __blk_run_queue+0x3f/0x60 [<000000001c4453c8>] blk_execute_rq_nowait+0x98/0xd0 [<00000000d17ec79f>] blk_execute_rq+0x3a/0x50 [<00000000a7654b6e>] scsi_execute+0x113/0x250 [<00000000fd78f7cd>] sd_sync_cache+0x95/0x160 [<0000000024dacb14>] sd_shutdown+0x9b/0xd0 [<00000000e9101710>] sd_remove+0x5f/0xb0 [<00000000c43f0d63>] device_release_driver_internal+0x13c/0x1f0 [<00000000e8ad57b6>] bus_remove_device+0xe9/0x160 [<00000000713a7b8a>] device_del+0x120/0x320 [<00000000e5db670c>] __scsi_remove_device+0x115/0x150 [<00000000eccbef30>] scsi_forget_host+0x20/0x60 [<00000000cd5a0738>] scsi_remove_host+0x6d/0x120 Cc: stable(a)vger.kernel.org Signed-off-by: Luis Henriques <lhenriques(a)suse.com> --- drivers/scsi/scsi_debug.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/scsi/scsi_debug.c b/drivers/scsi/scsi_debug.c index 24d7496cd9e2..364e71861bfd 100644 --- a/drivers/scsi/scsi_debug.c +++ b/drivers/scsi/scsi_debug.c @@ -5507,9 +5507,9 @@ static void __exit scsi_debug_exit(void) int k = sdebug_add_host; stop_all_queued(); - free_all_queued(); for (; k; k--) sdebug_remove_adapter(); + free_all_queued(); driver_unregister(&sdebug_driverfs_driver); bus_unregister(&pseudo_lld_bus); root_device_unregister(pseudo_primary);

Memblock layout affects the pfn ranges covered by node/zone.

This causes shrinking node 0's pfn range because it is calculated by the address range of memblock.memory. So some of struct pages in the gap range are left uninitialized. We have a function zero_resv_unavail() which does zeroing the struct pages within the reserved unavailable range (i.e. memblock.memory && !memblock.reserved). This patch utilizes it to cover all unavailable ranges by putting them into memblock.reserved.

Consider that we have a VM with 2 NUMA nodes and each node has 4GB memory, and the default (no memmap= given) memblock layout is like below: MEMBLOCK configuration: memory size = 0x00000001fff75c00 reserved size = 0x000000000300c000 memory.cnt = 0x4 memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0 memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0 memory[0x2] [0x0000000100000000-0x000000013fffffff], 0x0000000040000000 bytes on node 0 flags: 0x0 memory[0x3] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0 ... If you give memmap=1G!4G (so it just covers memory[0x2]), the range [0x100000000-0x13fffffff] is gone: MEMBLOCK configuration: memory size = 0x00000001bff75c00 reserved size = 0x000000000300c000 memory.cnt = 0x3 memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0 memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0 memory[0x2] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0 ... This causes shrinking node 0's pfn range because it is calculated by the address range of memblock.memory. So some of struct pages in the gap range are left uninitialized. We have a function zero_resv_unavail() which does zeroing the struct pages outside memblock.memory, but currently it covers only the reserved unavailable range (i.e. memblock.memory && !memblock.reserved). This patch extends it to cover all unavailable range, which fixes the reported issue.

Hi, The patch has been in the mainline, and I have verified the commit can be cherry-picked cleanly to these 3 stable branches mentioned in the subject. When the patch was originally submitted, I did add a " Cc: stable(a)vger.kernel.org" tag: https://lkml.org/lkml/2018/6/6/766 . It looks somehow the tag was left out. Thanks, -- Dexuan

[PATCH 4.4] iio:buffer: make length types match kfifo types

by Ben Hutchings

From: Martin Kelly <mkelly(a)xevo.com> commit c043ec1ca5baae63726aae32abbe003192bc6eec upstream. Currently, we use int for buffer length and bytes_per_datum. However, kfifo uses unsigned int for length and size_t for element size. We need to make sure these matches or we will have bugs related to overflow (in the range between INT_MAX and UINT_MAX for length, for example). In addition, set_bytes_per_datum uses size_t while bytes_per_datum is an int, which would cause bugs for large values of bytes_per_datum. Change buffer length to use unsigned int and bytes_per_datum to use size_t.

Applied "spi: cadence: Change usleep_range() to udelay(), for atomic context" to the spi tree

by Mark Brown

The patch spi: cadence: Change usleep_range() to udelay(), for atomic context has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[PATCH v3 2/2] drm/rockchip: vop: fix irq disabled after vop driver probed

by Heiko Stuebner

From: Sandy Huang <hjc(a)rock-chips.com> The vop irq is shared between vop and iommu and irq probing in the iommu driver moved to the probe function recently. This can in some cases lead to a stall if the irq is triggered while the vop driver still has it disabled, but the vop irq handler gets called. But there is no real need to disable the irq, as the vop can simply also track its enabled state and ignore irqs in that case. For this we can simply check the power-domain state of the vop, similar to how the iommu driver does it. So remove the enable/disable handling and add appropriate condition to the irq handler. changes in v2: - move to just check the power-domain state - add clock handling changes in v3: - clarify comment to speak of runtime-pm not power-domain Fixes: d0b912bd4c23 ("iommu/rockchip: Request irqs in rk_iommu_probe()") Cc: stable(a)vger.kernel.org Signed-off-by: Sandy Huang <hjc(a)rock-chips.com> Signed-off-by: Heiko Stuebner <heiko(a)sntech.de> Tested-by: Ezequiel Garcia <ezequiel(a)collabora.com> --- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 28 ++++++++++++++------- 1 file changed, 19 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_vop.c b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c index 9a1f272e41c7..ae8a69793aed 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_vop.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c @@ -573,8 +573,6 @@ static int vop_enable(struct drm_crtc *crtc) spin_unlock(&vop->reg_lock); - enable_irq(vop->irq); - drm_crtc_vblank_on(crtc); return 0; @@ -618,8 +616,6 @@ static void vop_crtc_atomic_disable(struct drm_crtc *crtc, vop_dsp_hold_valid_irq_disable(vop); - disable_irq(vop->irq); - vop->is_enabled = false; /* @@ -1195,6 +1191,16 @@ static irqreturn_t vop_isr(int irq, void *data) uint32_t active_irqs; int ret = IRQ_NONE; + /* + * The irq is shared with the iommu.

[PATCH] Revert "drm/sun4i: Handle DRM_BUS_FLAG_PIXDATA_*EDGE"

by Paul Kocialkowski

This reverts commit 2c17a4368aad2b88b68e4390c819e226cf320f70. The offending commit triggers a run-time fault when accessing the panel element of the sun4i_tcon structure when no such panel is attached. It was apparently assumed in said commit that a panel is always used with the TCON. Although it is often the case, this is not always true. For instance a bridge might be used instead of a panel. This issue was discovered using an A13-OLinuXino, that uses the TCON in RGB mode for a simple DAC-based VGA bridge.

[PATCH] tcp: do not overshoot window_clamp in tcp_rcv_space_adjust()

by Guenter Roeck

From: Eric Dumazet <edumazet(a)google.com> commit 02db55718d53f9d426cee504c27fb768e9ed4ffe upstream. While rcvbuf is properly clamped by tcp_rmem[2], rcvwin is left to a potentially too big value. It has no serious effect, since : 1) tcp_grow_window() has very strict checks. 2) window_clamp can be mangled by user space to any value anyway. tcp_init_buffer_space() and companions use tcp_full_space(), we use tcp_win_from_space() to avoid reloading sk->sk_rcvbuf Signed-off-by: Eric Dumazet <edumazet(a)google.com> Acked-by: Soheil Hassas Yeganeh <soheil(a)google.com> Acked-by: Wei Wang <weiwan(a)google.com> Acked-by: Neal Cardwell <ncardwell(a)google.com> Signed-off-by: David S.

TCP receive windows broken in 4.14.48

by Benjamin Gilbert

Hi, 4.14.48 can cause abnormally small TCP receive windows when the sender is faster than the receiver; see https://github.com/coreos/bugs/issues/2457 for details. Reverting "tcp: avoid integer overflows in tcp_rcv_space_adjust()" fixes it. Backporting 02db55718d53 ("tcp: do not overshoot window_clamp in tcp_rcv_space_adjust()"), which is its parent commit upstream, also fixes it. --Benjamin Gilbert

[PATCH] extcon: Release locking when sending the notification of connector state

by Chanwoo Choi

Previously, extcon used the spinlock before calling the notifier_call_chain to prevent the scheduled out of task and to prevent the notification delay. When spinlock is locked for sending the notification, deadlock issue occured on the side of extcon consumer device. To fix this issue, extcon consumer device should always use the work. it is always not reasonable to use work. To fix this issue on extcon consumer device, release locking when sending the notification of connector state.
