[patch 5/9] mm: do not boost watermarks to avoid fragmentation for the DISCONTIG memory model

by akpm＠linux-foundation.org

From: Mel Gorman <mgorman(a)techsingularity.net> Subject: mm: do not boost watermarks to avoid fragmentation for the DISCONTIG memory model Mikulas Patocka reported that 1c30844d2dfe ("mm: reclaim small amounts of memory when an external fragmentation event occurs") "broke" memory management on parisc. The machine is not NUMA but the DISCONTIG model creates three pgdats even though it's a UMA machine for the following ranges 0) Start 0x0000000000000000 End 0x000000003fffffff Size 1024 MB 1) Start 0x0000000100000000 End 0x00000001bfdfffff Size 3070 MB 2) Start 0x0000004040000000 End 0x00000040ffffffff Size 3072 MB Mikulas reported: With the patch 1c30844d2, the kernel will incorrectly reclaim the first zone when it fills up, ignoring the fact that there are two completely free zones. Basiscally, it limits cache size to 1GiB. For example, if I run: # dd if=/dev/sda of=/dev/null bs=1M count=2048 - with the proper kernel, there should be "Buffers - 2GiB" when this command finishes. With the patch 1c30844d2, buffers will consume just 1GiB or slightly more, because the kernel was incorrectly reclaiming them. The page allocator and reclaim makes assumptions that pgdats really represent NUMA nodes and zones represent ranges and makes decisions on that basis. Watermark boosting for small pgdats leads to unexpected results even though this would have behaved reasonably on SPARSEMEM. DISCONTIG is essentially deprecated and even parisc plans to move to SPARSEMEM so there is no need to be fancy, this patch simply disables watermark boosting by default on DISCONTIGMEM.

[patch 2/9] zram: pass down the bvec we need to read into in the work struct

by akpm＠linux-foundation.org

From: Jérôme Glisse <jglisse(a)redhat.com> Subject: zram: pass down the bvec we need to read into in the work struct When scheduling work item to read page we need to pass down the proper bvec struct which points to the page to read into. Before this patch it uses a randomly initialized bvec (only if PAGE_SIZE != 4096) which is wrong. Note that without this patch on arch/kernel where PAGE_SIZE != 4096 userspace could read random memory through a zram block device (thought userspace probably would have no control on the address being read).

[tip:sched/urgent] sched/numa: Fix a possible divide-by-zero

If a task migrates to another CPU, then se.exec_start is set to that CPU's rq_clock_task() by update_stats_curr_start(). Specifically, the new value might be before the old value due to clock skew. So then if in numa_get_avg_runtime() the expression: 'now - p->last_task_numa_placement' ends up as -1, then the divider '*period + 1' in task_numa_placement() is 0 and things go bang. Similar to update_curr(), check if time goes backwards to avoid this.

patch "mm/memory_hotplug: Do not unlock when fails to take the" added to driver-core-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled mm/memory_hotplug: Do not unlock when fails to take the to my driver-core git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git in the driver-core-testing 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 be merged to the driver-core-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From d2ab99403ee00d8014e651728a4702ea1ae5e52c Mon Sep 17 00:00:00 2001 From: zhong jiang <zhongjiang(a)huawei.com> Date: Mon, 8 Apr 2019 12:07:17 +0800 Subject: mm/memory_hotplug: Do not unlock when fails to take the device_hotplug_lock When adding the memory by probing memory block in sysfs interface, there is an obvious issue that we will unlock the device_hotplug_lock when fails to takes it.

[PATCH] brcmfmac: Add DMI nvram filename quirk for ACEPC T8 and T11 mini PCs

by Hans de Goede

The ACEPC T8 and T11 mini PCs contain quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: "brcmfmac43455-sdio.Default string-Default string.txt" as nvram file which is way too generic. The DMI strings on which we are matching are somewhat generic too, but "To be filled by O.E.M." is less common then "Default string" and the system-sku and bios-version strings are pretty unique. Beside the DMI strings we also check the wifi-module chip-id and revision. I'm confident that the combination of all this is unique. Both the T8 and T11 use the same wifi-module, this commit adds DMI quirks for both mini PCs pointing to brcmfmac43455-sdio.acepc-t8.txt .

[PATCH] mwl8k: Fix rate_idx underflow

by Petr Štetiar

It was reported on OpenWrt bug tracking system[1], that several users are affected by the endless reboot of their routers if they configure 5GHz interface with channel 44 or 48. The reboot loop is caused by the following excessive number of WARN_ON messages: WARNING: CPU: 0 PID: 0 at backports-4.19.23-1/net/mac80211/rx.c:4516 ieee80211_rx_napi+0x1fc/0xa54 [mac80211] as the messages are being correctly emitted by the following guard: case RX_ENC_LEGACY: if (WARN_ON(status->rate_idx >= sband->n_bitrates)) as the rate_idx is in this case erroneously set to 251 (0xfb). This fix simply converts previously used magic number to proper constant and guards against substraction which is leading to the currently observed underflow. 1. https://bugs.openwrt.org/index.php?do=details&task_id=2218 Fixes: 854783444bab ("mwl8k: properly set receive status rate index on 5 GHz receive") Cc: <stable(a)vger.kernel.org> Tested-by: Eubert Bao <bunnier(a)gmail.com> Reported-by: Eubert Bao <bunnier(a)gmail.com> Signed-off-by: Petr Štetiar <ynezz(a)true.cz> --- drivers/net/wireless/marvell/mwl8k.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/drivers/net/wireless/marvell/mwl8k.c b/drivers/net/wireless/marvell/mwl8k.c index 8e4e9b6..ffc565a 100644 --- a/drivers/net/wireless/marvell/mwl8k.c +++ b/drivers/net/wireless/marvell/mwl8k.c @@ -441,6 +441,9 @@ struct mwl8k_sta { #define MWL8K_CMD_UPDATE_STADB 0x1123 #define MWL8K_CMD_BASTREAM 0x1125 +#define MWL8K_LEGACY_5G_RATE_OFFSET \ + (ARRAY_SIZE(mwl8k_rates_24) - ARRAY_SIZE(mwl8k_rates_50)) + static const char *mwl8k_cmd_name(__le16 cmd, char *buf, int bufsize) { u16 command = le16_to_cpu(cmd); @@ -1016,8 +1019,9 @@ static void mwl8k_rxd_ap_refill(void *_rxd, dma_addr_t addr, int len) if (rxd->channel > 14) { status->band = NL80211_BAND_5GHZ; - if (!(status->encoding == RX_ENC_HT)) - status->rate_idx -= 5; + if (!(status->encoding == RX_ENC_HT) && + status->rate_idx >= MWL8K_LEGACY_5G_RATE_OFFSET) + status->rate_idx -= MWL8K_LEGACY_5G_RATE_OFFSET; } else { status->band = NL80211_BAND_2GHZ; } @@ -1124,8 +1128,9 @@ static void mwl8k_rxd_sta_refill(void *_rxd, dma_addr_t addr, int len) if (rxd->channel > 14) { status->band = NL80211_BAND_5GHZ; - if (!(status->encoding == RX_ENC_HT)) - status->rate_idx -= 5; + if (!(status->encoding == RX_ENC_HT) && + status->rate_idx >= MWL8K_LEGACY_5G_RATE_OFFSET) + status->rate_idx -= MWL8K_LEGACY_5G_RATE_OFFSET; } else { status->band = NL80211_BAND_2GHZ; } -- 1.9.1

[PATCH] ext4: fix use-after-free race with debug_want_extra_isize

by Barret Rhoden

When remounting with debug_want_extra_isize, we were not performing the same checks that we do during a normal mount. That allowed us to set a value for s_want_extra_isize that reached outside the s_inode_size. Reported-by: syzbot+f584efa0ac7213c226b7(a)syzkaller.appspotmail.com Signed-off-by: Barret Rhoden <brho(a)google.com> Cc: stable(a)vger.kernel.org --- - In the current code, it looks like someone could mount with want_extra_isize with some value > 0 but less than the minimums in the s_es. If that's a bug, I can submit a follow-on patch. - Similarly, on a failed remount, sbi->s_want_extra_isize is changed to the remounted value. I can fix that too if it's a problem. - Is it OK to remount with a smaller s_want_extra_isize than the previous mount?

patch "TTY: serial_core, add ->install" added to tty-next

This is a note to let you know that I've just added the patch titled TTY: serial_core, add ->install to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-next branch.

The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From 4cdd17ba1dff20ffc99fdbd2e6f0201fc7fe67df Mon Sep 17 00:00:00 2001 From: Jiri Slaby <jslaby(a)suse.cz> Date: Wed, 17 Apr 2019 10:58:53 +0200 Subject: TTY: serial_core, add ->install We need to compute the uart state only on the first open. This is usually what is done in the ->install hook. serial_core used to do this in ->open on every open. So move it to ->install. As a side effect, it ensures the state is set properly in the window after tty_init_dev is called, but before uart_open. This fixes a bunch of races between tty_open and flush_to_ldisc we were dealing with recently. One of such bugs was attempted to fix in commit fedb5760648a (serial: fix race between flush_to_ldisc and tty_open), but it only took care of a couple of functions (uart_start and uart_unthrottle). I was able to reproduce the crash on a SLE system, but in uart_write_room which is also called from flush_to_ldisc via process_echoes. I was *unable* to reproduce the bug locally.

[PATCH] pci/quirks: Add quirk to reset nvgpu at boot for the Lenovo ThinkPad P50

by Lyude Paul

On a very specific subset of ThinkPad P50 SKUs, particularly ones that come with a Quadro M1000M chip instead of the M2000M variant, the BIOS seems to have a very nasty habit of not always resetting the secondary Nvidia GPU between full reboots if the laptop is configured in Hybrid Graphics mode. The reason for this happening is unknown, but the following steps and possibly a good bit of patience will reproduce the issue: 1. Boot up the laptop normally in Hybrid graphics mode 2. Make sure nouveau is loaded and that the GPU is awake 2. Allow the nvidia GPU to runtime suspend itself after being idle 3. Reboot the machine, the more sudden the better (e.g sysrq-b may help) 4. If nouveau loads up properly, reboot the machine again and go back to step 2 until you reproduce the issue This results in some very strange behavior: the GPU will quite literally be left in exactly the same state it was in when the previously booted kernel started the reboot. This has all sorts of bad sideaffects: for starters, this completely breaks nouveau starting with a mysterious EVO channel failure that happens well before we've actually used the EVO channel for anything: nouveau 0000:01:00.0: disp: chid 0 mthd 0000 data 00000400 00001000 00000002 Later on, this causes us to timeout trying to bring up the GR ctx: ------------[ cut here ]------------ nouveau 0000:01:00.0: timeout WARNING: CPU: 0 PID: 12 at drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxgf100.c:1547 gf100_grctx_generate+0x7b2/0x850 [nouveau] Modules linked in: nouveau mxm_wmi i915 crc32c_intel ttm i2c_algo_bit serio_raw drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops xhci_pci drm xhci_hcd i2c_core wmi video CPU: 0 PID: 12 Comm: kworker/0:1 Not tainted 5.0.0-rc5Lyude-Test+ #29 Hardware name: LENOVO 20EQS64N0B/20EQS64N0B, BIOS N1EET82W (1.55 ) 12/18/2018 Workqueue: events_long drm_dp_mst_link_probe_work [drm_kms_helper] RIP: 0010:gf100_grctx_generate+0x7b2/0x850 [nouveau] Code: 85 d2 75 04 48 8b 57 10 48 89 95 28 ff ff ff e8 b4 37 0e e1 48 8b 95 28 ff ff ff 48 c7 c7 b1 97 57 a0 48 89 c6 e8 5a 38 c0 e0 <0f> 0b e9 b9 fd ff ff 48 8b 85 60 ff ff ff 48 8b 40 10 48 8b 78 10 RSP: 0018:ffffc900000b77f0 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff888871af8000 RCX: 0000000000000000 RDX: ffff88887f41dfe0 RSI: ffff88887f415698 RDI: ffff88887f415698 RBP: ffffc900000b78c8 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000000 R12: ffff888872118000 R13: 0000000000000000 R14: ffffffffa0551420 R15: ffffc900000b7818 FS: 0000000000000000(0000) GS:ffff88887f400000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00005644d0556ca8 CR3: 0000000002214006 CR4: 00000000003606f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: gf100_gr_init_ctxctl+0x27b/0x2d0 [nouveau] gf100_gr_init+0x5bd/0x5e0 [nouveau] gf100_gr_init_+0x61/0x70 [nouveau] nvkm_gr_init+0x1d/0x20 [nouveau] nvkm_engine_init+0xcb/0x210 [nouveau] nvkm_subdev_init+0xd6/0x230 [nouveau] nvkm_engine_ref.part.0+0x52/0x70 [nouveau] nvkm_engine_ref+0x13/0x20 [nouveau] nvkm_ioctl_new+0x12c/0x260 [nouveau] ? nvkm_fifo_chan_child_del+0xa0/0xa0 [nouveau] ? gf100_gr_dtor+0xe0/0xe0 [nouveau] nvkm_ioctl+0xe2/0x180 [nouveau] nvkm_client_ioctl+0x12/0x20 [nouveau] nvif_object_ioctl+0x47/0x50 [nouveau] nvif_object_init+0xc8/0x120 [nouveau] nvc0_fbcon_accel_init+0x5c/0x960 [nouveau] nouveau_fbcon_create+0x5a5/0x5d0 [nouveau] ? drm_setup_crtcs+0x27b/0xcb0 [drm_kms_helper] ? __lock_is_held+0x5e/0xa0 __drm_fb_helper_initial_config_and_unlock+0x27c/0x520 [drm_kms_helper] drm_fb_helper_hotplug_event.part.29+0xae/0xc0 [drm_kms_helper] drm_fb_helper_hotplug_event+0x1c/0x30 [drm_kms_helper] nouveau_fbcon_output_poll_changed+0xb8/0x110 [nouveau] drm_kms_helper_hotplug_event+0x2a/0x40 [drm_kms_helper] drm_dp_send_link_address+0x176/0x1c0 [drm_kms_helper] drm_dp_check_and_send_link_address+0xa0/0xb0 [drm_kms_helper] drm_dp_mst_link_probe_work+0xa4/0xc0 [drm_kms_helper] process_one_work+0x22f/0x5c0 worker_thread+0x44/0x3a0 kthread+0x12b/0x150 ? wq_pool_ids_show+0x140/0x140 ? kthread_create_on_node+0x60/0x60 ret_from_fork+0x3a/0x50 irq event stamp: 22490 hardirqs last enabled at (22489): [<ffffffff8113281d>] console_unlock+0x44d/0x5f0 hardirqs last disabled at (22490): [<ffffffff81001c03>] trace_hardirqs_off_thunk+0x1a/0x1c softirqs last enabled at (22486): [<ffffffff81c00330>] __do_softirq+0x330/0x44d softirqs last disabled at (22479): [<ffffffff810c3105>] irq_exit+0xe5/0xf0 WARNING: CPU: 0 PID: 12 at drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxgf100.c:1547 gf100_grctx_generate+0x7b2/0x850 [nouveau] ---[ end trace bf0976ed88b122a8 ]--- nouveau 0000:01:00.0: gr: wait for idle timeout (en: 1, ctxsw: 0, busy: 1) nouveau 0000:01:00.0: gr: wait for idle timeout (en: 1, ctxsw: 0, busy: 1) nouveau 0000:01:00.0: fifo: fault 01 [WRITE] at 0000000000008000 engine 00 [GR] client 15 [HUB/SCC_NB] reason c4 [] on channel -1 [0000000000 unknown] >From which the GPU never manages to recover. Booting without nouveau loading causes issues as well, since the GPU starts sending spurious interrupts that cause other device's IRQs to get disabled by the kernel: irq 16: nobody cared (try booting with the "irqpoll" option) … handlers: [<000000007faa9e99>] i801_isr [i2c_i801] Disabling IRQ #16 … serio: RMI4 PS/2 pass-through port at rmi4-00.fn03 i801_smbus 0000:00:1f.4: Timeout waiting for interrupt! i801_smbus 0000:00:1f.4: Transaction timeout rmi4_f03 rmi4-00.fn03: rmi_f03_pt_write: Failed to write to F03 TX register (-110). i801_smbus 0000:00:1f.4: Timeout waiting for interrupt! i801_smbus 0000:00:1f.4: Transaction timeout rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts! Which in turn causes the touchpad and sometimes even other things to get disabled. Since the GPU staying on causes problems even without nouveau's intervention, we can't fix this problem from nouveau itself. We have to fix it as early as possible in the boot sequence in order to make sure that the GPU is in a clean state before it has a chance to spam us with interrupts and break things. So to do this, we add a new pci quirk using DECLARE_PCI_FIXUP_CLASS_FINAL that will be invoked before the PCI probe at boot finishes. From there, we check to make sure that this is indeed the specific P50 variant of this GPU. We also make sure that the GPU PCI device is advertising NoReset- in order to prevent us from trying to reset the GPU when the machine is in Dedicated graphics mode (where the GPU being initialized by the BIOS is normal and expected). Finally, we try mapping the MMIO space for the GPU which should only work if the GPU is actually active in D0 mode. We can then read the magic 0x2240c register on the GPU, which will have bit 1 set if the GPU's firmware has already been posted during a previous boot. Once we've confirmed all of this, we reset the PCI device and re-disable it - bringing the GPU back into a healthy state.
