Validate the requested format and updated the stored format accordingly. 3. Return the format actually set. 4. Propagate the format from sink to source.

However, scale is done between forwarding period timer and refilling cfs bandwidth runtime, which means that period timer is forwarded with old "period" while runtime is refilled with scaled "quota". Move do_sched_cfs_period_timer() before scaling to solve this.

However the current test, based on kgdb_connected is flawed: it both over-matches and under-matches. The over match occurs because kgdb_connected is set when gdb attaches to the stub and remains set during normal running. This is relatively harmelss because in almost all cases irq_disabled() will be false. The under match is more serious. When kdb is used instead of kgdb to access the debugger then kgdb_connected is not set in all the places that the debug core updates sw breakpoints (and hence flushes the icache). This can lead to deadlock. Fix by replacing the ad-hoc check with the proper kgdb macro. This also allows us to drop the #ifdef wrapper.

First, the code does not correctly reject an all-ones 32-bit immediate, and returns an undefined instruction encoding. Second, the code incorrectly rejects some 32-bit immediates that are actually encodable as logical immediates. The root cause is that the code uses a default mask of 64-bit all-ones, even for 32-bit immediates. This causes an issue later on when the default mask is used to fill the top bits of the immediate with ones, shown here: /* * Pattern: 0..01..10..01..1 * * Fill the unused top bits with ones, and check if * the result is a valid immediate (all ones with a * contiguous ranges of zeroes). */ imm |= ~mask; if (!range_of_ones(~imm)) return AARCH64_BREAK_FAULT; To see the problem, consider an immediate of the form 0..01..10..01..1, where the upper 32 bits are zero, such as 0x80000001. The code checks if ~(imm | ~mask) contains a range of ones: the incorrect mask yields 1..10..01..10..0, which fails the check; the correct mask yields 0..01..10..0, which succeeds. The fix for both issues is to generate a correct mask based on the instruction immediate size, and use the mask to check for all-ones, all-zeroes, and values wider than the mask. Currently, arch/arm64/kvm/va_layout.c is the only user of this function, which uses 64-bit immediates and therefore won't trigger these bugs. We tested the new code against llvm-mc with all 1,302 encodable 32-bit logical immediates and all 5,334 encodable 64-bit logical immediates.

This isn't good for multiple reasons. First of all seeing the device is placed on APB bus (which makes it accessible from any CPU core), accessible over MMIO and having the DYNIRQ flag set we can be sure that manually binding the timer to any CPU just isn't correct. By doing so we just set an extra limitation on device usage. This also doesn't reflect the device actual capability, since by setting the IRQ affinity we can make it virtually local to any CPU. Secondly imagine if you had a real CPU-local timer with the same rating and the same CPU-affinity. In this case if DW APB timer was registered first, then due to the clockevent framework tick-timer selection procedure we'll end up with the real CPU-local timer being left unselected for clock-events tracking. But on most of the platforms (MIPS/ARM/etc) such timers are normally embedded into the CPU core and are accessible with much better performance then devices placed on APB. For instance in MIPS architectures there is r4k-timer, which is CPU-local, assigned with the same rating, and normally its clockevent device is registered after the platform-specific one. So in order to fix all of these issues let's make the DW APB Timer CPU affinity being optional and deactivated by passing a negative CPU id, which will effectively set the DW APB clockevent timer cpumask to 'cpu_possible_mask'.

However if btrfs_next_leaf() returns an error (a value < 0), we should just stop and return the error, and not behave as if nothing has happened, since in that case we do not have a way to know if there is a next leaf or we are currently at the last leaf already.

According to the patch, automatic measurements should be used for these kind of interfaces. But there are major flaws with this argumentation: * automatic measurements are not implemented * auto negotiation has nothing to do with the validity of the retrieved values The first point has to be fixed by a longer patch series. The "validity" part of the second point must be addressed in the same patch series by dropping the usage of ethtool's link_ksetting (thus always doing automatic measurements over ethernet).

While this fixes a problem where SDIO cards are not detected at all (because all commands simply timed out) this hurts SD card read performance a bit (in my tests between 10% to 20%). Trigger a soft reset after we got a CRC error or if the previous command timed out (just like the vendor driver from the same 3.10 kernel for the newer SDHC controller IP does). This fixes detection of SDIO cards and doesn't hurt SD card read performance at the same time. With this patch the initialization of an RTL8723BS SDIO card looks like this: req done (CMD52): -110: 00000000 00000000 00000000 00000000 clock 400000Hz busmode 2 powermode 2 cs 1 Vdd 21 width 1 timing 0 starting CMD0 arg 00000000 flags 000000c0 req done (CMD0): 0: 00000000 00000000 00000000 00000000 clock 400000Hz busmode 2 powermode 2 cs 0 Vdd 21 width 1 timing 0 starting CMD8 arg 000001aa flags 000002f5 req done (CMD8): -110: 00000000 00000000 00000000 00000000 starting CMD5 arg 00000000 flags 000002e1 req done (CMD5): 0: 90ff0000 00000000 00000000 00000000 starting CMD5 arg 00200000 flags 000002e1 req done (CMD5): 0: 90ff0000 00000000 00000000 00000000 starting CMD3 arg 00000000 flags 00000075 req done (CMD3): 0: 00010000 00000000 00000000 00000000 starting CMD7 arg 00010000 flags 00000015 req done (CMD7): 0: 00001e00 00000000 00000000 00000000 starting CMD52 arg 00000000 flags 00000195 req done (CMD52): 0: 00001032 00000000 00000000 00000000 [... more CMD52 omitted ...] clock 400000Hz busmode 2 powermode 2 cs 0 Vdd 21 width 1 timing 2 clock 50000000Hz busmode 2 powermode 2 cs 0 Vdd 21 width 1 timing 2 starting CMD52 arg 00000e00 flags 00000195 req done (CMD52): 0: 00001000 00000000 00000000 00000000 starting CMD52 arg 80000e02 flags 00000195 req done (CMD52): 0: 00001002 00000000 00000000 00000000 clock 50000000Hz busmode 2 powermode 2 cs 0 Vdd 21 width 4 timing 2 starting CMD52 arg 00020000 flags 00000195 req done (CMD52): 0: 00001007 00000000 00000000 00000000 [... more CMD52 omitted ...] new high speed SDIO card at address 0001 Fixes: ed80a13bb4c4c9 ("mmc: meson-mx-sdio: Add a driver for the Amlogic Meson8 and Meson8b SoCs") Signed-off-by: Martin Blumenstingl Link: https://lore.kernel.org/r/20200503222805.2668941-1-martin.blumenstingl@googlemail.com Tested-by: Tobias Baumann <017623705678@o2online.de> Signed-off-by: Ulf Hansson Signed-off-by: Sasha Levin --- drivers/mmc/host/meson-mx-sdio.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/mmc/host/meson-mx-sdio.c b/drivers/mmc/host/meson-mx-sdio.c index 999214e8cf2b..360d523132bd 100644 --- a/drivers/mmc/host/meson-mx-sdio.c +++ b/drivers/mmc/host/meson-mx-sdio.c @@ -246,6 +246,9 @@ static void meson_mx_mmc_request_done(struct meson_mx_mmc_host *host) mrq = host->mrq;

But it turns out the SPI Rx-only transfers are broken since nothing pushing any data to the shift registers, so the Rx FIFO is left empty and the SPI core subsystems just returns a timeout error. Since DW DMAC driver doesn't support something like cyclic write operations of a single byte to a device register, the only way to support the Rx-only SPI transfers is to fake it by using a dummy Tx-buffer. This is what we intend to fix in this commit by setting the SPI_CONTROLLER_MUST_TX flag for DMA-capable platform.

With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, move such variables into the "case" where they're used or lift them up into the main function body. drivers/net/ethernet/intel/e1000/e1000_main.c: In function ‘e1000_xmit_frame’: drivers/net/ethernet/intel/e1000/e1000_main.c:3143:18: warning: statement will never be executed [-Wswitch-unreachable] 3143 | unsigned int pull_size; | ^~~~~~~~~ [1] https://bugs.llvm.org/show_bug.cgi?id=44916 Signed-off-by: Kees Cook Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher Signed-off-by: Sasha Levin --- drivers/net/ethernet/intel/e1000/e1000_main.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/net/ethernet/intel/e1000/e1000_main.c b/drivers/net/ethernet/intel/e1000/e1000_main.c index 86493fea56e4..f93ed70709c6 100644 --- a/drivers/net/ethernet/intel/e1000/e1000_main.c +++ b/drivers/net/ethernet/intel/e1000/e1000_main.c @@ -3140,8 +3140,9 @@ static netdev_tx_t e1000_xmit_frame(struct sk_buff *skb, hdr_len = skb_transport_offset(skb) + tcp_hdrlen(skb); if (skb->data_len && hdr_len == len) { switch (hw->mac_type) { + case e1000_82544: { unsigned int pull_size; - case e1000_82544: + /* Make sure we have room to chop off 4 bytes, * and that the end alignment will work out to * this hardware's requirements @@ -3162,6 +3163,7 @@ static netdev_tx_t e1000_xmit_frame(struct sk_buff *skb, } len = skb_headlen(skb); break; + } default: /* do nothing */ break; From patchwork Fri Jun 19 14:31:16 2020 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Greg Kroah-Hartman X-Patchwork-Id: 224143 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org X-Spam-Level: X-Spam-Status: No, score=-9.8 required=3.0 tests=DKIMWL_WL_HIGH, DKIM_SIGNED, DKIM_VALID, HEADER_FROM_DIFFERENT_DOMAINS, INCLUDES_PATCH, MAILING_LIST_MULTI, SIGNED_OFF_BY,SPF_HELO_NONE,SPF_PASS,USER_AGENT_GIT autolearn=ham autolearn_force=no version=3.4.0 Received: from mail.kernel.org (mail.kernel.org [198.145.29.99]) by smtp.lore.kernel.org (Postfix) with ESMTP id 28009C433E1 for ; Fri, 19 Jun 2020 15:08:53 +0000 (UTC) Received: from vger.kernel.org (vger.kernel.org [23.128.96.18]) by mail.kernel.org (Postfix) with ESMTP id D571E21D7E for ; Fri, 19 Jun 2020 15:08:52 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=kernel.org; s=default; t=1592579332; bh=JpyXvZPwGmhcDX7HBvEqn00iZ7V++vRJV0NKykGQJf4=; h=From:To:Cc:Subject:Date:In-Reply-To:References:List-ID:From; b=oqOtGjwAkVQwtftxYnY81d/BT+yCyuMRpWakdH1sFczhyIWr3xwQ+roMULxGZoI8T WdXzN/+NZgDFVOdZWeFIHtwWU2sWMRMCA4R5o49dsMpVkxqScSwx1VF3B9NgH2J/Gx vBT9qgZRGREYR3PMBRuKG98vr27t0sukzL2zT1BU= Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S2391810AbgFSPIv (ORCPT ); Fri, 19 Jun 2020 11:08:51 -0400 Received: from mail.kernel.org ([198.145.29.99]:38386 "EHLO mail.kernel.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S2390579AbgFSPIv (ORCPT ); Fri, 19 Jun 2020 11:08:51 -0400 Received: from localhost (83-86-89-107.cable.dynamic.v4.ziggo.nl [83.86.89.107]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by mail.kernel.org (Postfix) with ESMTPSA id BB6F821BE5; Fri, 19 Jun 2020 15:08:49 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=kernel.org; s=default; t=1592579330; bh=JpyXvZPwGmhcDX7HBvEqn00iZ7V++vRJV0NKykGQJf4=; h=From:To:Cc:Subject:Date:In-Reply-To:References:From; b=nCYv4LReRPf6M3u8iNat87eQeKbLGifJNZa0+ZKNsTWZzvzLb7IGSQOetmr8UPt7E /mm/h3h2NTT7umkBjzY3xayPeHDjWceALH+Q8ouOpplYLf7THsrxnv8yFkD77dmFdY Mi2ZA/QBPOyVU7E9FxKJtk+qeSGhwMLAXKlr+mNA= From: Greg Kroah-Hartman To: linux-kernel@vger.kernel.org Cc: Greg Kroah-Hartman , stable@vger.kernel.org, Rob Herring , Jitao Shi , Chun-Kuang Hu , Sasha Levin Subject: [PATCH 5.4 065/261] dt-bindings: display: mediatek: control dpi pins mode to avoid leakage Date: Fri, 19 Jun 2020 16:31:16 +0200 Message-Id: <20200619141653.030997554@linuxfoundation.org> X-Mailer: git-send-email 2.27.0 In-Reply-To: <20200619141649.878808811@linuxfoundation.org> References: <20200619141649.878808811@linuxfoundation.org> User-Agent: quilt/0.66 MIME-Version: 1.0 Sender: stable-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: stable@vger.kernel.org From: Jitao Shi [ Upstream commit b0ff9b590733079f7f9453e5976a9dd2630949e3 ] Add property "pinctrl-names" to swap pin mode between gpio and dpi mode.

(1) On the Loongson and SiByte platform arch/mips/loongson64/dma.c arch/mips/sibyte/common/dma.c void __init plat_swiotlb_setup(void) { swiotlb_init(1); } kernel/dma/swiotlb.c void __init swiotlb_init(int verbose) { ... vstart = memblock_alloc_low(PAGE_ALIGN(bytes), PAGE_SIZE); if (vstart && !swiotlb_init_with_tbl(vstart, io_tlb_nslabs, verbose)) return; ... pr_warn("Cannot allocate buffer"); no_iotlb_memory = true; } phys_addr_t swiotlb_tbl_map_single() { ... if (no_iotlb_memory) panic("Can not allocate SWIOTLB buffer earlier ..."); ... } (2) On the Cavium OCTEON platform arch/mips/cavium-octeon/dma-octeon.c void __init plat_swiotlb_setup(void) { ... octeon_swiotlb = memblock_alloc_low(swiotlbsize, PAGE_SIZE); if (!octeon_swiotlb) panic("%s: Failed to allocate %zu bytes align=%lx\n", __func__, swiotlbsize, PAGE_SIZE); ... } Because IO_TLB_DEFAULT_SIZE is 64M, if the rest size of low memory is less than 64M when call plat_swiotlb_setup(), we can easily reproduce the panic case. In order to reduce the possibility of kernel panic when failed to get IO TLB memory under CONFIG_SWIOTLB, it is better to allocate low memory as small as possible before plat_swiotlb_setup(), so make sparse_init() using top-down allocation.

This makes the code use just "BCM" as prefix for the filename to pass to request-firmware, making it harder for users to figure out which firmware they need. This especially is problematic with the UART attached BCM4324B5 where this leads to the filename being just "BCM.hcd". Add the 2 missing devices to subver tables. This has been tested on: 1. A Dell XPS15 9550 where this makes btbcm.c try to load "BCM20703A1-0a5c-6410.hcd" before it tries to load "BCM-0a5c-6410.hcd". 2.

This special case for umul_ppmm for MIPS64r6 was added in commit bbc25bee37d2b ("lib/mpi: Fix umul_ppmm() for MIPS64r6"), due to GCC being inefficient and emitting a __multi3 intrinsic. There is no such issue with clang; with this patch applied, I can build this configuration without any problems and there are no link errors like mentioned in the commit above (which I can still reproduce with GCC 9.3.0 when that commit is reverted). Only use this definition when GCC is being used. This really should have been caught by commit b0c091ae04f67 ("lib/mpi: Eliminate unused umul_ppmm definitions for MIPS") when I was messing around in this area but I was not testing 64-bit MIPS at the time.

If it's over 31 then that results in undefined behavior (shift wrapping) and that leads to a Smatch static checker warning. We already cap the value later so we can silence the warning just by re-ordering the existing checks. I think the UBSan checker will also catch this bug at runtime and generate a warning.

Specifically if we migrate to a new core after reading the processor id and the previous core takes a breakpoint then we will evaluate true if we read kgdb_active before we get the IPI to bring us to halt. Fix this by checking irqs_disabled() first. Interrupts are always disabled when we are executing the kgdb trap so this is an acceptable prerequisite. This also allows us to replace raw_smp_processor_id() with smp_processor_id() since the short circuit logic will prevent warnings from PREEMPT_DEBUG.

But the idr entry added, which is used to track these packet is not getting removed. Hence, during unload, in wmi cleanup, all the entries in IDR are removed and the corresponding buffer is attempted to be freed. This can cause a situation where one packet is attempted to be freed twice. Fix this error by rmeoving the msdu from the idr list when the sending of a management packet over wmi fails.

Given that there's no information, it's best to keep vrate as-is in this state. Before 7cd806a9a953 ("iocost: improve nr_lagging handling"), this was the case - if the device isn't missing QoS targets and nothing is being throttled, busy_level was reset to zero. While fixing nr_lagging handling, 7cd806a9a953 ("iocost: improve nr_lagging handling") broke this. Now, while the device is hitting QoS targets and nothing is being throttled, vrate keeps getting adjusted according to the existing busy_level. This led to vrate keeping climing till it hits max when there's an IO issuer with limited request concurrency if the vrate started low. vrate starts getting adjusted upwards until the issuer can issue IOs w/o being throttled. From then on, QoS targets keeps getting met and nothing on the system needs throttling and vrate keeps getting increased due to the existing busy_level. This patch makes the following changes to the busy_level logic. * Reset busy_level if nr_shortages is zero to avoid the above scenario. * Make non-zero nr_lagging block lowering nr_level but still clear positive busy_level if there's clear non-saturation signal - QoS targets are met and nr_shortages is non-zero. nr_lagging's role is preventing adjusting vrate upwards while there are long-running commands and it shouldn't keep busy_level positive while there's clear non-saturation signal. * Restructure code for clarity and add comments.

It was an understandable mistake because the code was a bit confusing and the free was done in the wrong place. The "skb" pointer is freed in both _rtl_usb_tx_urb_setup() and _rtl_usb_transmit(). The free belongs _rtl_usb_transmit() instead of _rtl_usb_tx_urb_setup() and I've cleaned the code up a bit to hopefully make it more clear.

It would be better to convert the code not to use linked list for associated stations storage (since the chip has a limited number of associated stations anyway - it could just be an array).

Boot up picasso platform, launches desktop, Don't do anything (APU enter into "gfxoff" state) 2. Remote login to platform using SSH, then type the command line: sudo su -c "echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level" sudo su -c "echo 2 > /sys/class/drm/card0/device/pp_dpm_sclk" (fix SCLK to 1400MHz) 3. Move the mouse around in Window 4. Phenomenon : The screen frozen Tester will switch sclk level during glmark2 run time. APU will enter "gfxoff" state intermittently during glmark2 run time. The system got hanged if fix GFXCLK to 1400MHz when APU is in "gfxoff" state. [Debug] 1. Fix SCLK to X MHz 1400: screen frozen, screen black, then OS will reboot. 1300: screen frozen. 1200: screen frozen, screen black. 1100: screen frozen, screen black, then OS will reboot. 1000: screen frozen, screen black. 900: screen frozen, screen black, then OS will reboot. 800: Situation Nomal, issue disappear. 700: Situation Nomal, issue disappear. 2. SBIOS setting: AMD CBS --> SMU Debug Options -->SMU Debug --> "GFX DLDO Psm Margin Control": 50 : Situation Nomal, issue disappear. 45 : Situation Nomal, issue disappear. 40 : Situation Nomal, issue disappear. 35 : Situation Nomal, issue disappear. 30 : screen black. 25 : screen frozen, then blurred screen. 20 : screen frozen. 15 : screen black. 10 : screen frozen. 5 : screen frozen, then blurred screen. 3. Disable GFXOFF feature Situation Nomal, issue disappear. [Why] Through a period of time debugging with Sys Eng team and SMU team, Sys Eng team said this is voltage/frequency marginal issue not a F/W or H/W bug. This experiment proves that default targetPsm [for f=1400MHz] is not sufficient when GFXOFF is enabled on Picasso. SMU team think it is an odd test conditions to force sclk="1400MHz" when GPU is in "gfxoff" state，then wake up the GFX. SCLK should be in the "lowest frequency" when gfxoff. [How] Disable gfxoff when setting manual mode. Enable gfxoff when setting other mode(exiting manual mode) again. By the way, from the user point of view, now that user switch to manual mode and force SCLK Frequency, he don't want SCLK be controlled by workload.It becomes meaningless to "switch to manual mode" if APU enter "gfxoff" due to lack of workload at this point.

But it introduces two issues here: - one SOC has two instances, they have different bit - different SOCs may have different offset and bit So to support wake-on-lan feature on other i.MX platforms, it should configure the GPR reigster offset and bit from DT. So the patch is to improve the commit da722186f654 (net: fec: set GPR bit on suspend by DT configuration) to support multiple ethernet instances on i.MX series. v2: * switch back to store the quirks bitmask in driver_data v3: * suggested by Sascha Hauer, use a struct fec_devinfo for abstracting differences between different hardware variants, it can give more freedom to describe the differences.

For some commands it means waiting longer than needed for the timeout to expire, which may not a big issue, but still. For other commands, like for an erase (CMD38) that uses a R1B response, may require longer timeouts than 1s. In these cases, we may end up treating the command as it failed, while it just needed some more time to complete successfully.

For some commands it means waiting longer than needed for the timer to expire, which may not a big issue, but still. For other commands, like for an erase (CMD38) that uses a R1B response, may require longer timeouts than 1s. In these cases, we may end up treating the command as it failed, while it just needed some more time to complete successfully. Fix the problem by respecting the cmd->busy_timeout, which is provided by the mmc core.

This can lead to some static analysis tools such as the compiler sanitizers complaining about double free problems. Since ice_init_interrupt_scheme already unrolls internally on failure, there is no need to call ice_clear_interrupt_scheme when it fails. Add a new unroll label and use that instead.

This model reports a chassis-type of 10 / "Notebook" which is not on the recently introduced chassis-type whitelist Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's") added a chassis-type whitelist and only listed 31 / "Convertible" as being capable of generating valid SW_TABLET_MOD events. Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on "Detachable" and "Portable" chassis-types") extended the whitelist with chassis-types 8 / "Portable" and 32 / "Detachable". And now we need to exten the whitelist again with 10 / "Notebook"... The issue original fixed by the whitelist is really a ACPI DSDT bug on the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode even though it is not a 2-in-1 at all, but a regular laptop. So since this is a workaround for a DSDT issue on that specific model, instead of extending the whitelist over and over again, lets switch to a blacklist and only blacklist the chassis-type of the model for which the chassis-type check was added. Note this also fixes the current version of the code no longer checking if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

When an old device has new fsid through 'btrfs device add -f ' our fs_devices list has an alien device in one of the fs_devices lists. By having an alien device in fs_devices, we have two issues so far 1. missing device does not not show as missing in the userland 2. degraded mount will fail Both issues are caused by the fact that there's an alien device in the fs_devices list. (Alien means that it does not belong to the filesystem, identified by fsid, or does not contain btrfs filesystem at all, eg. due to overwrite). A device can be scanned/added through the control device ioctls SCAN_DEV, DEVICES_READY or by ADD_DEV. And device coming through the control device is checked against the all other devices in the lists, but this was not the case for ADD_DEV. This patch fixes both issues above by removing the alien device.

For a typical-missing device the generation number is zero so fs_devices::latest_bdev will never point to it. But if the missing device is due to alienation [1], then device::generation is not zero and if it is greater or equal to the rest of device generations in the list, then fs_devices::latest_bdev ends up pointing to the missing device and reports the error like [2]. [1] We maintain devices of a fsid (as in fs_device::fsid) in the fs_devices::devices list, a device is considered as an alien device if its fsid does not match with the fs_device::fsid Consider a working filesystem with raid1: $ mkfs.btrfs -f -d raid1 -m raid1 /dev/sda /dev/sdb $ mount /dev/sda /mnt-raid1 $ umount /mnt-raid1 While mnt-raid1 was unmounted the user force-adds one of its devices to another btrfs filesystem: $ mkfs.btrfs -f /dev/sdc $ mount /dev/sdc /mnt-single $ btrfs dev add -f /dev/sda /mnt-single Now the original mnt-raid1 fails to mount in degraded mode, because fs_devices::latest_bdev is pointing to the alien device. $ mount -o degraded /dev/sdb /mnt-raid1 [2] mount: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so. kernel: BTRFS warning (device sdb): devid 1 uuid 072a0192-675b-4d5a-8640-a5cf2b2c704d is missing kernel: BTRFS error (device sdb): failed to read devices kernel: BTRFS error (device sdb): open_ctree failed Fix the root cause by checking if the device is not missing before it can be considered for the fs_devices::latest_bdev.

Nikolay noticed a bunch of test failures with my global rsv steal patches. At first he thought they were introduced by them, but they've been failing for a while with 64k nodes. The problem is with 64k nodes we have a global reserve that calculates out to 13MiB on a freshly made file system, which only has 8MiB of metadata space. Because of changes I previously made we no longer account for the global reserve in the overcommit logic, which means we correctly allow overcommit to happen even though we are already overcommitted. However in some corner cases, for example btrfs/170, we will allocate the entire file system up with data chunks before we have enough space pressure to allocate a metadata chunk. Then once the fs is full we ENOSPC out because we cannot overcommit and the global reserve is taking up all of the available space. The most ideal way to deal with this is to change our space reservation stuff to take into account the height of the tree's that we're modifying, so that our global reserve calculation does not end up so obscenely large. However that is a huge undertaking. Instead fix this by forcing a chunk allocation if the global reserve is larger than the total metadata space. This gives us essentially the same behavior that happened before, we get a chunk allocated and these tests can pass. This is meant to be a stop-gap measure until we can tackle the "tree height only" project.

If an error happens while running dellaloc in COW mode for a range, we can end up calling extent_clear_unlock_delalloc() for a range that goes beyond our range's end offset by 1 byte, which affects 1 extra page. This results in clearing bits and doing page operations (such as a page unlock) outside our target range. Fix that by calling extent_clear_unlock_delalloc() with an inclusive end offset, instead of an exclusive end offset, at cow_file_range().

We always preallocate a data extent for writing a free space cache, which causes writeback to always try the nocow path first, since the free space inode has the prealloc bit set in its flags. However if the block group that contains the data extent for the space cache has been turned to RO mode due to a running scrub or balance for example, we have to fallback to the cow path. In that case once a new data extent is allocated we end up calling btrfs_add_reserved_bytes(), which decrements the counter named bytes_may_use from the data space_info object with the expection that this counter was previously incremented with the same amount (the size of the data extent). However when we started writeout of the space cache at cache_save_setup(), we incremented the value of the bytes_may_use counter through a call to btrfs_check_data_free_space() and then decremented it through a call to btrfs_prealloc_file_range_trans() immediately after. So when starting the writeback if we fallback to cow mode we have to increment the counter bytes_may_use of the data space_info again to compensate for the extent allocation done by the cow path.

If the cow path is successful the counter is decremented after extent allocation (by btrfs_add_reserved_bytes()), if it fails it ends up being decremented as well when clearing the delalloc range (extent_clear_unlock_delalloc()). This could be triggered sporadically by the test case btrfs/061 from fstests.

Initializing struct pages is a long task and keeping interrupts disabled for the duration of this operation introduces a number of problems. 1. jiffies are not updated for long period of time, and thus incorrect time is reported. See proposed solution and discussion here: lkml/20200311123848.118638-1-shile.zhang@linux.alibaba.com 2. It prevents farther improving deferred page initialization by allowing intra-node multi-threading. We are keeping interrupts disabled to solve a rather theoretical problem that was never observed in real world (See 3a2d7fa8a3d5). Let's keep interrupts enabled. In case we ever encounter a scenario where an interrupt thread wants to allocate large amount of memory this early in boot we can deal with that by growing zone (see deferred_grow_zone()) by the needed amount before starting deferred_init_memmap() threads.

Patch series "initialize deferred pages with interrupts enabled", v4. Keep interrupts enabled during deferred page initialization in order to make code more modular and allow jiffies to update. Original approach, and discussion can be found here: http://lkml.kernel.org/r/20200311123848.118638-1-shile.zhang@linux.alibaba.com This patch (of 3): deferred_init_memmap() disables interrupts the entire time, so it calls touch_nmi_watchdog() periodically to avoid soft lockup splats. Soon it will run with interrupts enabled, at which point cond_resched() should be used instead. deferred_grow_zone() makes the same watchdog calls through code shared with deferred init but will continue to run with interrupts disabled, so it can't call cond_resched(). Pull the watchdog calls up to these two places to allow the first to be changed later, independently of the second. The frequency reduces from twice per pageblock (init and free) to once per max order block.

If the template field 'd' is chosen and the digest to be added to the measurement entry was not calculated with SHA1 or MD5, it is recalculated with SHA1, by using the passed file descriptor. However, this cannot be done for boot_aggregate, because there is no file descriptor. This patch adds a call to ima_calc_boot_aggregate() in ima_eventdigest_init(), so that the digest can be recalculated also for the boot_aggregate entry.

'igrab(d_inode(dentry->d_parent))' without holding dentry->d_lock is broken because without d_lock, d_parent can be concurrently changed due to a rename(). Then if the old directory is immediately deleted, old d_parent->inode can be NULL. That causes a NULL dereference in igrab(). To fix this, use dget_parent() to safely grab a reference to the parent dentry, which pins the inode. This also eliminates the need to use d_find_any_alias() other than for the initial inode, as we no longer throw away the dentry at each step. This is an extremely hard race to hit, but it is possible. Adding a udelay() in between the reads of ->d_parent and its ->d_inode makes it reproducible on a no-journal filesystem using the following program: #include #include int main() { if (fork()) { for (;;) { mkdir("dir1", 0700); int fd = open("dir1/file", O_RDWR|O_CREAT|O_SYNC); write(fd, "X", 1); close(fd); } } else { mkdir("dir2", 0700); for (;;) { rename("dir1/file", "dir2/file"); rmdir("dir1"); } } } Fixes: d59729f4e794 ("ext4: fix races in ext4_sync_parent()") Cc: stable@vger.kernel.org Signed-off-by: Eric Biggers Link: https://lore.kernel.org/r/20200506183140.541194-1-ebiggers@kernel.org Signed-off-by: Theodore Ts'o Signed-off-by: Greg Kroah-Hartman --- fs/ext4/fsync.c | 28 +++++++++++++--------------- 1 file changed, 13 insertions(+), 15 deletions(-) --- a/fs/ext4/fsync.c +++ b/fs/ext4/fsync.c @@ -44,30 +44,28 @@ */ static int ext4_sync_parent(struct inode *inode) { - struct dentry *dentry = NULL; - struct inode *next; + struct dentry *dentry, *next; int ret = 0; if (!ext4_test_inode_state(inode, EXT4_STATE_NEWENTRY)) return 0; - inode = igrab(inode); + dentry = d_find_any_alias(inode); + if (!dentry) + return 0; while (ext4_test_inode_state(inode, EXT4_STATE_NEWENTRY)) { ext4_clear_inode_state(inode, EXT4_STATE_NEWENTRY); - dentry = d_find_any_alias(inode); - if (!dentry) - break; - next = igrab(d_inode(dentry->d_parent)); + + next = dget_parent(dentry); dput(dentry); - if (!next) - break; - iput(inode); - inode = next; + dentry = next; + inode = dentry->d_inode; + /* * The directory inode may have gone through rmdir by now.

If the call to uart_add_one_port() in serial8250_register_8250_port() fails, a half-initialized entry in the serial_8250ports[] array is left behind. A subsequent reprobe of the same serial port causes that entry to be reused. Because uart->port.dev is set, uart_remove_one_port() is called for the half-initialized entry and bails out with an error message: bcm2835-aux-uart 3f215040.serial: Removing wrong port: (null) != (ptrval) The same happens on failure of mctrl_gpio_init() since commit 4a96895f74c9 ("tty/serial/8250: use mctrl_gpio helpers"). Fix by zeroing the uart->port.dev pointer in the probe error path. The bug was introduced in v2.6.10 by historical commit befff6f5bf5f ("[SERIAL] Add new port registration/unregistration functions."): https://git.kernel.org/tglx/history/c/befff6f5bf5f The commit added an unconditional call to uart_remove_one_port() in serial8250_register_port(). In v3.7, commit 835d844d1a28 ("8250_pnp: do pnp probe before legacy probe") made that call conditional on uart->port.dev which allows me to fix the issue by zeroing that pointer in the error path. Thus, the present commit will fix the problem as far back as v3.7 whereas still older versions need to also cherry-pick 835d844d1a28.

Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43 did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43 will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers.

In ov5640_remove(), the driver destroys the sensor->lock first, and then calls v4l2_ctrl_handler_free(), resulting in the use of the destroyed mutex. Fix this by calling moving the mutex_destroy() to the end of the cleanup sequence, as there's no need to destroy the mutex as early as possible.

We can't get correct speed under that state: $ cat /sys/class/net/enp3s0/speed 1000 In addition to that, an error can also be spotted in dmesg: [ 385.991957] igb 0000:03:00.0 enp3s0: PCIe link lost Since device can only be runtime suspended when there's no link partner, we can skip reading register and let the following logic set speed and duplex with correct status. The more generic approach will be wrap get_link_ksettings() with begin() and complete() callbacks. However, for this particular issue, begin() calls igb_runtime_resume() , which tries to rtnl_lock() while the lock is already hold by upper ethtool layer. So let's take this approach until the igb_runtime_resume() no longer needs to hold rtnl_lock.

Commit a8be2af0218c ("pinctrl: samsung: Write external wakeup interrupt mask") started writing the eint wakeup mask from the pinctrl driver. Unfortunately, it made the assumption that the private retention data was always a regmap while in the case of s5pv210 it is a raw pointer to the clock base (as the eint wakeup mask not in the PMU as with newer Exynos platforms).

Unfortunately the callers of cpu_pm_notify() don't init *nr_calls. This potentially means you could get too many or two few calls to CPU_PM_ENTER_FAILED or CPU_CLUSTER_PM_ENTER_FAILED depending on the luck of the stack. Let's fix this.

GPIO lines for the CM36651 sensor I2C bus use the normal not the inverted polarity. This bug has been there since adding the CM36651 sensor by commit 85cb4e0bd229 ("ARM: dts: add cm36651 light/proximity sensor node for exynos4412-trats2"), but went unnoticed because the "i2c-gpio" driver ignored the GPIO polarity specified in the device-tree. The recent conversion of "i2c-gpio" driver to the new, descriptor based GPIO API, automatically made it the DT-specified polarity aware, what broke the CM36651 sensor operation.

At the time being, KASAN_SHADOW_END is 0x100000000, which is 0 in 32 bits representation. This leads to a couple of issues: - kasan_remap_early_shadow_ro() does nothing because the comparison k_cur < k_end is always false. - In ptdump, address comparison for markers display fails and the marker's name is printed at the start of the KASAN area instead of being printed at the end. However, there is no need to shadow the KASAN shadow area itself, so the KASAN shadow area can stop shadowing memory at the start of itself. With a PAGE_OFFSET set to 0xc0000000, KASAN shadow area is then going from 0xf8000000 to 0xff000000.

The device tree CPU features binding includes FSCR bit numbers which Linux is instructed to set by firmware. Whether that's a good idea or not, in the case of the DSCR the Linux implementation has a hard requirement that the FSCR_DSCR bit not be set by default. We use it to track when a process reads/writes to DSCR, so it must be clear to begin with. So if firmware tells us to set FSCR_DSCR we must ignore it. Currently this does not cause a bug in our DSCR handling because the value of FSCR that the device tree CPU features code establishes is only used by swapper. All other tasks use the value hard coded in init_task.thread.fscr. However we'd like to fix that in a future commit, at which point this will become necessary.

At boot the FSCR is initialised via one of two paths. On most systems it's set to a hard coded value in __init_FSCR(). On newer skiboot systems we use the device tree CPU features binding, where firmware can tell Linux what bits to set in FSCR (and HFSCR). In both cases the value that's configured at boot is not propagated into the init_task.thread.fscr value prior to the initial fork of init (pid 1), which means the value is not used by any processes other than swapper (the idle task). For the __init_FSCR() case this is OK, because the value in init_task.thread.fscr is initialised to something sensible. However it does mean that the value set in __init_FSCR() is not used other than for swapper, which is odd and confusing. The bigger problem is for the device tree CPU features case it prevents firmware from setting (or clearing) FSCR bits for use by user space. This means all existing kernels can not have features enabled/disabled by firmware if those features require setting/clearing FSCR bits. We can handle both cases by saving the FSCR value into init_task.thread.fscr after we have initialised it at boot. This fixes the bug for device tree CPU features, and will allow us to simplify the initialisation for the __init_FSCR() case in a future patch.

There is no valid case for supporting duplicate pseudoflavor registrations. Currently the silent acceptance of such registrations is hiding a bug. The rpcsec_gss_krb5 module registers 2 flavours but does not unregister them, so if you load, unload, reload the module, it will happily continue to use the old registration which now has pointers to the memory were the module was originally loaded. This could lead to unexpected results. So disallow duplicate registrations.

During ONFI detection, the CRC derived from the parameter page and the CRC supposed to be at the end of the parameter page are compared. If they do not match, the second then the third copies of the page are tried. The current implementation compares the newly derived CRC with the CRC contained in the first page only. So if this particular CRC area has been corrupted, then the detection will fail for a wrong reason. Fix this issue by checking the derived CRC against the right one.

Since commit 03db8b583d1c ("perf tools: Fix maps__find_symbol_by_name()") introduced map address range check in maps__find_symbol_by_name(), we can not get "_etext" from kernel map because _etext is placed on the edge of the kernel .text section (= kernel map in perf.) To fix this issue, this checks the address correctness by map address range information (map->start and map->end) instead of using _etext address. This can cause an error if the target inlined function is embedded in both __init function and normal function. For exaample, request_resource() is a normal function but also embedded in __init reserve_setup(). In this case, the probe point in reserve_setup() must be skipped. However, without this fix, it failes to setup all probe points: # ./perf probe -v request_resource probe-definition(0): request_resource symbol:request_resource file:(null) line:0 offset:0 return:0 lazy:(null) 0 arguments Looking at the vmlinux_path (8 entries long) Using /usr/lib/debug/lib/modules/5.5.17-200.fc31.x86_64/vmlinux for symbols Open Debuginfo file: /usr/lib/debug/lib/modules/5.5.17-200.fc31.x86_64/vmlinux Try to find probe point from debuginfo.
