[PATCH 2/3] scsi: megaraid_sas: check user-provided offsets

by Arnd Bergmann

It sounds unwise to let user space pass an unchecked 32-bit offset into a kernel structure in an ioctl. This is an unsigned variable, so checking the upper bound for the size of the structure it points into is sufficient to avoid data corruption, but as the pointer might also be unaligned, it has to be written carefully as well. While I stumbled over this problem by reading the code, I did not continue checking the function for further problems like it.

Re: [PATCH AUTOSEL 5.4 006/130] drm/amd/display: Do not silently accept DCC for multiplane formats.

[PATCH v3 2/2] io_uring: patch up IOPOLL overflow_flush sync

by Pavel Begunkov

IOPOLL skips completion locking but keeps it under uring_lock, thus io_cqring_overflow_flush() and so io_cqring_events() need additional locking with uring_lock in some cases for IOPOLL. Remove __io_cqring_overflow_flush() from io_cqring_events(), introduce a wrapper around flush doing needed synchronisation and call it by hand.

[PATCH] btrfs: shrink delalloc pages instead of full inodes

by Josef Bacik

Commit 38d715f494f2 ("btrfs: use btrfs_start_delalloc_roots in shrink_delalloc") cleaned up how we do delalloc shrinking by utilizing some infrastructure we have in place to flush inodes that we use for device replace and snapshot. However this introduced a pretty serious performance regression. The root cause is because before we would generally use the normal writeback path to reclaim delalloc space, and for this we would provide it with the number of pages we wanted to flush. The referenced commit changed this to flush that many inodes, which drastically increased the amount of space we were flushing in certain cases, which severely affected performance. We cannot revert this patch unfortunately, because Filipe has another fix that requires the ability to skip flushing inodes that are being cloned in certain scenarios, which means we need to keep using our flushing infrastructure or risk re-introducing the deadlock. Instead to fix this problem we can go back to providing btrfs_start_delalloc_roots with a number of pages to flush, and then set up a writeback_control and utilize sync_inode() to handle the flushing for us. This gives us the same behavior we had prior to the fix, while still allowing us to avoid the deadlock that was fixed by Filipe. The user reported reproducer was a simple untarring of a large tarball of the source code for Firefox. The results are as follows 5.9 0m54.258s 5.10 1m26.212s Patch 0m38.800s We are significantly faster because of the work I did around improving ENOSPC flushing in 5.10 and 5.11, so reverting to the previous write out behavior gave us a pretty big boost.

[PATCH 2/2] net: dsa: lantiq_gswip: Fix GSWIP_MII_CFG(p) register access

by Martin Blumenstingl

There is one GSWIP_MII_CFG register for each switch-port except the CPU port. The register offset for the first port is 0x0, 0x02 for the second, 0x04 for the third and so on. Update the driver to not only restrict the GSWIP_MII_CFG registers to ports 0, 1 and 5. Handle ports 0..5 instead but skip the CPU port. This means we are not overwriting the configuration for the third port (port two since we start counting from zero) with the settings for the sixth port (with number five) anymore. The GSWIP_MII_PCDU(p) registers are not updated because there's really only three (one for each of the following ports: 0, 1, 5).

[PATCH] btrfs: Use the normal writeback path for flushing delalloc

by Josef Bacik

This is a revert for 38d715f494f2 ("btrfs: use btrfs_start_delalloc_roots in shrink_delalloc"). A user reported a problem where performance was significantly worse with this patch applied. The problem needs to be fixed with proper pre-flushing, and changes to how we deal with the work queues for the inodes. However that work is much more complicated than is acceptable for stable, and simply reverting this patch fixes the problem. The original patch was a cleanup of the code, so it's fine to revert it. My numbers for the original reported test, which was untarring a copy of the firefox sources, are as follows 5.9 0m54.258s 5.10 1m26.212s Fix 0m35.038s cc: stable(a)vger.kernel.org # 5.10 Reported-by: René Rebe <rene(a)exactcode.de> Fixes: 38d715f494f2 ("btrfs: use btrfs_start_delalloc_roots in shrink_delalloc") Signed-off-by: Josef Bacik <josef(a)toxicpanda.com> --- Dave, this is ontop of linus's branch, because we've changed the arguments for btrfs_start_delalloc_roots in misc-next, and this needs to go back to 5.10 ASAP.

patch "usb: gadget: configfs: Preserve function ordering after bind failure" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: gadget: configfs: Preserve function ordering after bind failure to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-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 6cd0fe91387917be48e91385a572a69dfac2f3f7 Mon Sep 17 00:00:00 2001 From: Chandana Kishori Chiluveru <cchiluve(a)codeaurora.org> Date: Tue, 29 Dec 2020 14:44:43 -0800 Subject: usb: gadget: configfs: Preserve function ordering after bind failure When binding the ConfigFS gadget to a UDC, the functions in each configuration are added in list order. However, if usb_add_function() fails, the failed function is put back on its configuration's func_list and purge_configs_funcs() is called to further clean up. purge_configs_funcs() iterates over the configurations and functions in forward order, calling unbind() on each of the previously added functions. But after doing so, each function gets moved to the tail of the configuration's func_list. This results in reshuffling the original order of the functions within a configuration such that the failed function now appears first even though it may have originally appeared in the middle or even end of the list. At this point if the ConfigFS gadget is attempted to re-bind to the UDC, the functions will be added in a different order than intended, with the only recourse being to remove and relink the functions all over again. An example of this as follows: ln -s functions/mass_storage.0 configs/c.1 ln -s functions/ncm.0 configs/c.1 ln -s functions/ffs.adb configs/c.1 # oops, forgot to start adbd echo "<udc device>" > UDC # fails start adbd echo "<udc device>" > UDC # now succeeds, but... # bind order is # "ADB", mass_storage, ncm [30133.118289] configfs-gadget gadget: adding 'Mass Storage Function'/ffffff810af87200 to config 'c'/ffffff817d6a2520 [30133.119875] configfs-gadget gadget: adding 'cdc_network'/ffffff80f48d1a00 to config 'c'/ffffff817d6a2520 [30133.119974] using random self ethernet address [30133.120002] using random host ethernet address [30133.139604] usb0: HOST MAC 3e:27:46:ba:3e:26 [30133.140015] usb0: MAC 6e:28:7e:42:66:6a [30133.140062] configfs-gadget gadget: adding 'Function FS Gadget'/ffffff80f3868438 to config 'c'/ffffff817d6a2520 [30133.140081] configfs-gadget gadget: adding 'Function FS Gadget'/ffffff80f3868438 --> -19 [30133.140098] configfs-gadget gadget: unbind function 'Mass Storage Function'/ffffff810af87200 [30133.140119] configfs-gadget gadget: unbind function 'cdc_network'/ffffff80f48d1a00 [30133.173201] configfs-gadget a600000.dwc3: failed to start g1: -19 [30136.661933] init: starting service 'adbd'...

[PATCH v2 1/5] crypto: x86/gcm-aes-ni - prevent misaligned buffers on the stack

by Ard Biesheuvel

The GCM mode driver uses 16 byte aligned buffers on the stack to pass the IV to the asm helpers, but unfortunately, the x86 port does not guarantee that the stack pointer is 16 byte aligned upon entry in the first place. Since the compiler is not aware of this, it will not emit the additional stack realignment sequence that is needed, and so the alignment is not guaranteed to be more than 8 bytes. So instead, allocate some padding on the stack, and realign the IV pointer by hand.

[PATCH v3 2/2] dm crypt: use GFP_ATOMIC when allocating crypto requests from softirq

by Ignat Korchagin

Commit 39d42fa96ba1b7d2544db3f8ed5da8fb0d5cb877 made it possible for some code paths in dm-crypt to be executed in softirq context, when the underlying driver processes IO requests in interrupt/softirq context. In this case sometimes when allocating a new crypto request we may get a stacktrace like below: [ 210.103008][ C0] BUG: sleeping function called from invalid context at mm/mempool.c:381 [ 210.104746][ C0] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2602, name: fio [ 210.106599][ C0] CPU: 0 PID: 2602 Comm: fio Tainted: G W 5.10.0+ #50 [ 210.108331][ C0] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.0.0 02/06/2015 [ 210.110212][ C0] Call Trace: [ 210.110921][ C0] <IRQ> [ 210.111527][ C0] dump_stack+0x7d/0xa3 [ 210.112411][ C0] ___might_sleep.cold+0x122/0x151 [ 210.113527][ C0] mempool_alloc+0x16b/0x2f0 [ 210.114524][ C0] ?

[PATCH v3 1/2] dm crypt: do not wait for backlogged crypto request completion in softirq

by Ignat Korchagin

Commit 39d42fa96ba1b7d2544db3f8ed5da8fb0d5cb877 made it possible for some code paths in dm-crypt to be executed in softirq context, when the underlying driver processes IO requests in interrupt/softirq context. When Crypto API backlogs a crypto request, dm-crypt uses wait_for_completion to avoid sending further requests to an already overloaded crypto driver. However, if the code is executing in softirq context, we might get the following stacktrace: [ 210.235213][ C0] BUG: scheduling while atomic: fio/2602/0x00000102 [ 210.236701][ C0] Modules linked in: [ 210.237566][ C0] CPU: 0 PID: 2602 Comm: fio Tainted: G W 5.10.0+ #50 [ 210.239292][ C0] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.0.0 02/06/2015 [ 210.241233][ C0] Call Trace: [ 210.241946][ C0] <IRQ> [ 210.242561][ C0] dump_stack+0x7d/0xa3 [ 210.243466][ C0] __schedule_bug.cold+0xb3/0xc2 [ 210.244539][ C0] __schedule+0x156f/0x20d0 [ 210.245518][ C0] ? io_schedule_timeout+0x140/0x140 [ 210.246660][ C0] schedule+0xd0/0x270 [ 210.247541][ C0] schedule_timeout+0x1fb/0x280 [ 210.248586][ C0] ? usleep_range+0x150/0x150 [ 210.249624][ C0] ? unpoison_range+0x3a/0x60 [ 210.250632][ C0] ? ____kasan_kmalloc.constprop.0+0x82/0xa0 [ 210.251949][ C0] ? unpoison_range+0x3a/0x60 [ 210.252958][ C0] ? __prepare_to_swait+0xa7/0x190 [ 210.254067][ C0] do_wait_for_common+0x2ab/0x370 [ 210.255158][ C0] ? usleep_range+0x150/0x150 [ 210.256192][ C0] ? bit_wait_io_timeout+0x160/0x160 [ 210.257358][ C0] ? blk_update_request+0x757/0x1150 [ 210.258582][ C0] ? _raw_spin_lock_irq+0x82/0xd0 [ 210.259674][ C0] ? _raw_read_unlock_irqrestore+0x30/0x30 [ 210.260917][ C0] wait_for_completion+0x4c/0x90 [ 210.261971][ C0] crypt_convert+0x19a6/0x4c00 [ 210.263033][ C0] ? _raw_spin_lock_irqsave+0x87/0xe0 [ 210.264193][ C0] ? kasan_set_track+0x1c/0x30 [ 210.265191][ C0] ? crypt_iv_tcw_ctr+0x4a0/0x4a0 [ 210.266283][ C0] ? kmem_cache_free+0x104/0x470 [ 210.267363][ C0] ? crypt_endio+0x91/0x180 [ 210.268327][ C0] kcryptd_crypt_read_convert+0x30e/0x420 [ 210.269565][ C0] blk_update_request+0x757/0x1150 [ 210.270563][ C0] blk_mq_end_request+0x4b/0x480 [ 210.271680][ C0] blk_done_softirq+0x21d/0x340 [ 210.272775][ C0] ? _raw_spin_lock+0x81/0xd0 [ 210.273847][ C0] ? blk_mq_stop_hw_queue+0x30/0x30 [ 210.275031][ C0] ? _raw_read_lock_irq+0x40/0x40 [ 210.276182][ C0] __do_softirq+0x190/0x611 [ 210.277203][ C0] ? handle_edge_irq+0x221/0xb60 [ 210.278340][ C0] asm_call_irq_on_stack+0x12/0x20 [ 210.279514][ C0] </IRQ> [ 210.280164][ C0] do_softirq_own_stack+0x37/0x40 [ 210.281281][ C0] irq_exit_rcu+0x110/0x1b0 [ 210.282286][ C0] common_interrupt+0x74/0x120 [ 210.283376][ C0] asm_common_interrupt+0x1e/0x40 [ 210.284496][ C0] RIP: 0010:_aesni_enc1+0x65/0xb0 Fix this by making crypt_convert function reentrant from the point of a single bio and make dm-crypt defer further bio processing to a workqueue, if Crypto API backlogs a request in interrupt context.

[PATCH 1/2] pinctrl: ingenic: Fix JZ4760 support

by Paul Cercueil

- JZ4760 and JZ4760B have a similar register layout as the JZ4740, and don't use the new register layout, which was introduced with the JZ4770 SoC and not the JZ4760 or JZ4760B SoCs. - The JZ4740 code path only expected two function modes to be configurable for each pin, and wouldn't work with more than two. Fix it for the JZ4760, which has four configurable function modes. Fixes: 0257595a5cf4 ("pinctrl: Ingenic: Add pinctrl driver for JZ4760 and JZ4760B.")

[PATCH AUTOSEL 5.10 01/31] ARM: 9014/2: Replace string mem* functions for KASan

by Sasha Levin

From: Linus Walleij <linus.walleij(a)linaro.org> [ Upstream commit d6d51a96c7d63b7450860a3037f2d62388286a52 ] Functions like memset()/memmove()/memcpy() do a lot of memory accesses. If a bad pointer is passed to one of these functions it is important to catch this. Compiler instrumentation cannot do this since these functions are written in assembly. KASan replaces these memory functions with instrumented variants. The original functions are declared as weak symbols so that the strong definitions in mm/kasan/kasan.c can replace them. The original functions have aliases with a '__' prefix in their name, so we can call the non-instrumented variant if needed. We must use __memcpy()/__memset() in place of memcpy()/memset() when we copy .data to RAM and when we clear .bss, because kasan_early_init cannot be called before the initialization of .data and .bss. For the kernel compression and EFI libstub's custom string libraries we need a special quirk: even if these are built without KASan enabled, they rely on the global headers for their custom string libraries, which means that e.g. memcpy() will be defined to __memcpy() and we get link failures. Since these implementations are written i C rather than assembly we use e.g. __alias(memcpy) to redirected any users back to the local implementation.

The problematic lock ordering found by lockdep was: perf_event_open (exec_update_mutex -> ovl_i_mutex) chown (ovl_i_mutex -> sb_writes) sendfile (sb_writes -> p->lock) by reading from a proc file and writing to overlayfs proc_pid_syscall (p->lock -> exec_update_mutex) While looking at possible solutions it occured to me that all of the users and possible users involved only wanted to state of the given process to remain the same.

The sore point being perf holding exec_update_mutex() for a very long time, specifically across a whole bunch of filesystem ops in pmu::event_init() (uprobes) and anon_inode_getfile(). This then inverts against procfs code trying to take exec_update_mutex. Move the permission checks later, such that we need to hold the mutex over less code.

[PATCH] ACPI / scan: Don't create platform device for INT3515 ACPI nodes

by Heikki Krogerus

There are several reports about the tps6598x causing interrupt flood on boards with the INT3515 ACPI node, which then causes instability. There appears to be several problems with the interrupt. One problem is that the I2CSerialBus resources do not always map to the Interrupt resource with the same index, but that is not the only problem. We have not been able to come up with a solution for all the issues, and because of that disabling the device for now. The PD controller on these platforms is autonomous, and the purpose for the driver is primarily to supply status to the userspace, so this will not affect any functionality.

After that a fuse_do_getattr() call finds that attributes returned by the server are inconsistent, and calls make_bad_inode() which, among other things does: inode->i_mode = S_IFREG; This then confuses dnotify which doesn't tear down its structures properly and eventually crashes. Avoid calling make_bad_inode() on a live inode: switch to a private flag on the fuse inode. Also add the test to ops which the bad_inode_ops would have caught. This bug goes back to the initial merge of fuse in 2.6.14...

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 5d069dbe8aaf2a197142558b6fb2978189ba3454 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi <mszeredi(a)redhat.com> Date: Thu, 10 Dec 2020 15:33:14 +0100 Subject: [PATCH] fuse: fix bad inode Jan Kara's analysis of the syzbot report (edited): The reproducer opens a directory on FUSE filesystem, it then attaches dnotify mark to the open directory. After that a fuse_do_getattr() call finds that attributes returned by the server are inconsistent, and calls make_bad_inode() which, among other things does: inode->i_mode = S_IFREG; This then confuses dnotify which doesn't tear down its structures properly and eventually crashes. Avoid calling make_bad_inode() on a live inode: switch to a private flag on the fuse inode. Also add the test to ops which the bad_inode_ops would have caught. This bug goes back to the initial merge of fuse in 2.6.14...

My hope is this will solve some weird syzkaller hits related to sysfs as it could be possible that the parent of a netdev is another netdev, eg under bonding or some other syzkaller found netdev configuration. Nesting a ib_device under anything but a physical device is going to cause inconsistencies in sysfs during destructions.

[PATCH 00/10] Cover letter: fix a race in release_task when flushing the dentry

by Wen Yang

The dentries such as /proc/<pid>/ns/ have the DCACHE_OP_DELETE flag, they should be deleted when the process exits. Suppose the following race appears： release_task dput -> proc_flush_task -> dentry->d_op->d_delete(dentry) -> __exit_signal -> dentry->d_lockref.count-- and return. In the proc_flush_task(), if another process is using this dentry, it will not be deleted. At the same time, in dput(), d_op->d_delete() can be executed before __exit_signal(pid has not been hashed), d_delete returns false, so this dentry still cannot be deleted. This dentry will always be cached (although its count is 0 and the DCACHE_OP_DELETE flag is set), its parent denry will also be cached too, and these dentries can only be deleted when drop_caches is manually triggered. This will result in wasted memory. What's more troublesome is that these dentries reference pid, according to the commit f333c700c610 ("pidns: Add a limit on the number of pid namespaces"), if the pid cannot be released, it may result in the inability to create a new pid_ns. This problem occurred in our cluster environment (Linux 4.9 LTS). We could reproduce it by manually constructing a test program + adding some debugging switches in the kernel: * A test program to open the directory (/proc/<pid>/ns) [1] * Adding some debugging switches to the kernel, adding a delay between proc_flush_task and __exit_signal in release_task() [2] The test process is as follows: A, terminal #1 Turn on the debug switch: echo 1> /proc/sys/vm/dentry_debug_trace Execute the following unshare command: sudo unshare --pid --fork --mount-proc bash B, terminal #2 Find the pid of the unshare process: # pstree -p | grep unshare | `-sshd(716)---bash(718)--sudo(816)---unshare(817)---bash(818) Find the corresponding dentry: # dmesg | grep pid=818 [70.424722] XXX proc_pid_instantiate:3119 pid=818 tid=818 entry=818/ffff8802c7b670e8 C, terminal #3 Execute the opendir program, it will always open the /proc/818/ns/ directory: # ./a.out /proc/818/ns/ pid: 876 . .. net uts ipc pid user mnt cgroup D, go back to terminal #2 Turn on the debugging switches to construct the race: # echo 818> /proc/sys/vm/dentry_debug_pid # echo 1> /proc/sys/vm/dentry_debug_delay Kill the unshare process (pid 818). Since the debugging switches have been turned on, it will get stuck in release_task(): # kill -9 818 Then kill the process that opened the /proc/818/ns/ directory: # kill -9 876 Then turn off these debugging switches to allow the 818 process to exit: # echo 0> /proc/sys/vm/dentry_debug_delay # echo 0> /proc/sys/vm/dentry_debug_pid Checking the dmesg, we will find that the dentry(/proc/818/ns) ’s count is 0, and the flag is 2800cc (#define DCACHE_OP_DELETE 0x00000008), but it is still cached: # dmesg | grep ffff8802a3999548 … [565.559156] XXX dput:853 dentry=ns/ffff8802bea7b528, flag=2800cc, cnt=0, inode=ffff8802b38c2010, pdentry=818/ffff8802c7b670e8, pflag=20008c, pcnt=1, pinode=ffff8802c7812010, keywords: be cached It could also be verified via the crash tool: crash> dentry.d_flags,d_iname,d_inode,d_lockref -x ffff8802bea7b528 d_flags = 0x2800cc d_iname = "ns\000kkkkkkkkkkkkkkkkkkkkkkkkkkkk" d_inode = 0xffff8802b38c2010 d_lockref = { { lock_count = 0x0, { lock = { { rlock = { raw_lock = { { val = { counter = 0x0 }, { locked = 0x0, pending = 0x0 }, { locked_pending = 0x0, tail = 0x0 } } } } } }, count = 0x0 } } } crash> kmem ffff8802bea7b528 CACHE OBJSIZE ALLOCATED TOTAL SLABS SSIZE NAME ffff8802dd5f5900 192 23663 26130 871 16k dentry SLAB MEMORY NODE TOTAL ALLOCATED FREE ffffea000afa9e00 ffff8802bea78000 0 30 25 5 FREE / [ALLOCATED] [ffff8802bea7b520] PAGE PHYSICAL MAPPING INDEX CNT FLAGS ffffea000afa9ec0 2bea7b000 dead000000000400 0 0 2fffff80000000 crash> This series of patches is to fix this issue.

[PATCH 4.19 1/7] mm: drop meminit_pfn_in_nid as it is redundant

by Pavel Tatashin

From: Alexander Duyck <alexander.h.duyck(a)linux.intel.com> From: Alexander Duyck <alexander.h.duyck(a)linux.intel.com> commit 56ec43d8b02719402c9fcf984feb52ec2300f8a5 upstream. As best as I can tell the meminit_pfn_in_nid call is completely redundant. The deferred memory initialization is already making use of for_each_free_mem_range which in turn will call into __next_mem_range which will only return a memory range if it matches the node ID provided assuming it is not NUMA_NO_NODE. I am operating on the assumption that there are no zones or pgdata_t structures that have a NUMA node of NUMA_NO_NODE associated with them. If that is the case then __next_mem_range will never return a memory range that doesn't match the zone's node ID and as such the check is redundant. So one piece I would like to verify on this is if this works for ia64. Technically it was using a different approach to get the node ID, but it seems to have the node ID also encoded into the memblock. So I am assuming this is okay, but would like to get confirmation on that. On my x86_64 test system with 384GB of memory per node I saw a reduction in initialization time from 2.80s to 1.85s as a result of this patch.

This is specifically needed on x86 where gcc (typically) aligns larger objects like struct of_device_id with static extent on 32-byte boundaries which at best prevents matching on anything but the first entry. Specifying alignment when declaring variables suppresses this optimisation. Here's a 64-bit example where all entries are corrupt as 16 bytes of padding has been inserted before the first entry: ffffffff8266b4b0 D __clk_of_table ffffffff8266b4c0 d __of_table_fixed_factor_clk ffffffff8266b5a0 d __of_table_fixed_clk ffffffff8266b680 d __clk_of_table_sentinel And here's a 32-bit example where the 8-byte-aligned table happens to be placed on a 32-byte boundary so that all but the first entry are corrupt due to the 28 bytes of padding inserted between entries: 812b3ec0 D __irqchip_of_table 812b3ec0 d __of_table_irqchip1 812b3fa0 d __of_table_irqchip2 812b4080 d __of_table_irqchip3 812b4160 d irqchip_of_match_end Verified on x86 using gcc-9.3 and gcc-4.9 (which uses 64-byte alignment), and on arm using gcc-7.2. Note that there are no in-tree users of these tables on x86 currently (even if they are included in the image).

[PATCH fixes v3] platform/x86: ideapad-laptop: Disable touchpad_switch for ELAN0634

by Jiaxun Yang

Newer ideapads (e.g.: Yoga 14s, 720S 14) come with ELAN0634 touchpad do not use EC to switch touchpad. Reading VPCCMD_R_TOUCHPAD will return zero thus touchpad may be blocked unexpectedly. Writing VPCCMD_W_TOUCHPAD may cause a spurious key press. Add has_touchpad_switch to workaround these machines.

[RESEND PATCH] fs: Validate flags and capabilities before looking up path in ksys_umount

by Sargun Dhillon

ksys_umount was refactored to into split into another function (path_umount) to enable sharing code. This changed the order that flags and permissions are validated in, and made it so that user_path_at was called before validating flags and capabilities. Unfortunately, libfuse2[1] and libmount[2] rely on the old flag validation behaviour to determine whether or not the kernel supports UMOUNT_NOFOLLOW. The other path that this validation is being checked on is init_umount->path_umount->can_umount. That's all internal to the kernel.

[PATCH] ovl: use a dedicated semaphore for dir upperfile caching

by Icenowy Zheng

The function ovl_dir_real_file() currently uses the semaphore of the inode to synchronize write to the upperfile cache field. However, this function will get called by ovl_ioctl_set_flags(), which utilizes the inode semaphore too. In this case ovl_dir_real_file() will try to claim a lock that is owned by a function in its call stack, which won't get released before ovl_dir_real_file() returns. Define a dedicated semaphore for the upperfile cache, so that the deadlock won't happen.

[PATCH 4/5] bcache: introduce BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE for large bucket

by Coly Li

When large bucket feature was added, BCH_FEATURE_INCOMPAT_LARGE_BUCKET was introduced into the incompat feature set. It used bucket_size_hi (which was added at the tail of struct cache_sb_disk) to extend current 16bit bucket size to 32bit with existing bucket_size in struct cache_sb_disk. This is not a good idea, there are two obvious problems, - Bucket size is always value power of 2, if store log2(bucket size) in existing bucket_size of struct cache_sb_disk, it is unnecessary to add bucket_size_hi. - Macro csum_set() assumes d[SB_JOURNAL_BUCKETS] is the last member in struct cache_sb_disk, bucket_size_hi was added after d[] which makes csum_set calculate an unexpected super block checksum. To fix the above problems, this patch introduces a new incompat feature bit BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE, when this bit is set, it means bucket_size in struct cache_sb_disk stores the order of power-of-2 bucket size value. When user specifies a bucket size larger than 32768 sectors, BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE will be set to incompat feature set, and bucket_size stores log2(bucket size) more than store the real bucket size value. The obsoleted BCH_FEATURE_INCOMPAT_LARGE_BUCKET won't be used anymore, it is renamed to BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET and still only recognized by kernel driver for legacy compatible purpose. The previous bucket_size_hi is renmaed to obso_bucket_size_hi in struct cache_sb_disk and not used in bcache-tools anymore. For cache device created with BCH_FEATURE_INCOMPAT_LARGE_BUCKET feature, bcache-tools and kernel driver still recognize the feature string and display it as "obso_large_bucket". With this change, the unnecessary extra space extend of bcache on-disk super block can be avoided, and csum_set() may generate expected check sum as well.

[PATCH fixes v2] platform/x86: ideapad-laptop: Disable touchpad_switch for ELAN0634

by Jiaxun Yang

Newer ideapads (e.g.: Yoga 14s, 720S 14) come with ELAN0634 touchpad do not use EC to switch touchpad. Reading VPCCMD_R_TOUCHPAD will return zero thus touchpad may be blocked unexpectedly. Writing VPCCMD_W_TOUCHPAD may cause a spurious key press. Add has_touchpad_switch to workaround these machines.

[PATCH 3/4] kernel/io_uring: cancel io_uring before task works

by Pavel Begunkov

For cancelling io_uring requests it needs either to be able to run currently enqueued task_wokrs or having it shut down by that moment. Otherwise io_uring_cancel_files() may be waiting for requests that won't ever complete. Go with the first way and do cancellations before setting PF_EXITING and so before putting the task_work infrastructure into a transition state where task_work_run() would better not be called.

[PATCH 3/4] bcache: introduce BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE for large bucket

by Coly Li

When large bucket feature was added, BCH_FEATURE_INCOMPAT_LARGE_BUCKET was introduced into the incompat feature set. It used bucket_size_hi (which was added at the tail of struct cache_sb_disk) to extend current 16bit bucket size to 32bit with existing bucket_size in struct cache_sb_disk. This is not a good idea, there are two obvious problems, - Bucket size is always value power of 2, if store log2(bucket size) in existing bucket_size of struct cache_sb_disk, it is unnecessary to add bucket_size_hi. - Macro csum_set() assumes d[SB_JOURNAL_BUCKETS] is the last member in struct cache_sb_disk, bucket_size_hi was added after d[] which makes csum_set calculate an unexpected super block checksum. To fix the above problems, this patch introduces a new incompat feature bit BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE, when this bit is set, it means bucket_size in struct cache_sb_disk stores the order of power-of-2 bucket size value. When user specifies a bucket size larger than 32768 sectors, BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE will be set to incompat feature set, and bucket_size stores log2(bucket size) more than store the real bucket size value. The obsoleted BCH_FEATURE_INCOMPAT_LARGE_BUCKET won't be used anymore, it is renamed to BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET and still only recognized by kernel driver for legacy compatible purpose. The previous bucket_size_hi is renmaed to obso_bucket_size_hi in struct cache_sb_disk and not used in bcache-tools anymore. For cache device created with BCH_FEATURE_INCOMPAT_LARGE_BUCKET feature, bcache-tools and kernel driver still recognize the feature string and display it as "obso_large_bucket". With this change, the unnecessary extra space extend of bcache on-disk super block can be avoided, and csum_set() may generate expected check sum as well.

[PATCH 2/4] bcache: check unsupported feature sets for bcache register

by Coly Li

This patch adds the check for features which is incompatible for current supported feature sets.

[PATCH v2 1/2] dm crypt: use GFP_ATOMIC when allocating crypto requests from softirq

by Ignat Korchagin

Commit 39d42fa96ba1b7d2544db3f8ed5da8fb0d5cb877 made it possible for some code paths in dm-crypt to be executed in softirq context, when the underlying driver processes IO requests in interrupt/softirq context. In this case sometimes when allocating a new crypto request we may get a stacktrace like below: [ 210.103008][ C0] BUG: sleeping function called from invalid context at mm/mempool.c:381 [ 210.104746][ C0] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2602, name: fio [ 210.106599][ C0] CPU: 0 PID: 2602 Comm: fio Tainted: G W 5.10.0+ #50 [ 210.108331][ C0] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.0.0 02/06/2015 [ 210.110212][ C0] Call Trace: [ 210.110921][ C0] <IRQ> [ 210.111527][ C0] dump_stack+0x7d/0xa3 [ 210.112411][ C0] ___might_sleep.cold+0x122/0x151 [ 210.113527][ C0] mempool_alloc+0x16b/0x2f0 [ 210.114524][ C0] ?

[PATCH] platform/x86: ideapad-laptop: Add has_touchpad_switch

by Jiaxun Yang

Newer ideapads (e.g.: Yoga 14s, 720S 14) comes with I2C HID Touchpad and do not use EC to switch touchpad. Reading VPCCMD_R_TOUCHPAD will return zero thus touchpad may be blocked. Writing VPCCMD_W_TOUCHPAD may cause a spurious key press. Add has_touchpad_switch to workaround these machines.

The patch titled Subject: lib/zlib: fix inflating zlib streams on s390 has been removed from the -mm tree. Its filename was lib-zlib-fix-inflating-zlib-streams-on-s390.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Ilya Leoshkevich <iii(a)linux.ibm.com> Subject: lib/zlib: fix inflating zlib streams on s390 Decompressing zlib streams on s390 fails with "incorrect data check" error. Userspace zlib checks inflate_state.flags in order to byteswap checksums only for zlib streams, and s390 hardware inflate code, which was ported from there, tries to match this behavior. At the same time, kernel zlib does not use inflate_state.flags, so it contains essentially random values. For many use cases either zlib stream is zeroed out or checksum is not used, so this problem is masked, but at least SquashFS is still affected. Fix by always passing a checksum to and from the hardware as is, which matches zlib_inflate()'s expectations.

[merged] mm-memmap-defer-init-dosnt-work-as-expected.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: memmap defer init doesn't work as expected has been removed from the -mm tree. Its filename was mm-memmap-defer-init-dosnt-work-as-expected.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Baoquan He <bhe(a)redhat.com> Subject: mm: memmap defer init doesn't work as expected VMware observed a performance regression during memmap init on their platform, and bisected to commit 73a6e474cb376 ("mm: memmap_init: iterate over memblock regions rather that check each PFN") causing it. Before the commit: [0.033176] Normal zone: 1445888 pages used for memmap [0.033176] Normal zone: 89391104 pages, LIFO batch:63 [0.035851] ACPI: PM-Timer IO Port: 0x448 With commit [0.026874] Normal zone: 1445888 pages used for memmap [0.026875] Normal zone: 89391104 pages, LIFO batch:63 [2.028450] ACPI: PM-Timer IO Port: 0x448 The root cause is the current memmap defer init doesn't work as expected. Before, memmap_init_zone() was used to do memmap init of one whole zone, to initialize all low zones of one numa node, but defer memmap init of the last zone in that numa node. However, since commit 73a6e474cb376, function memmap_init() is adapted to iterater over memblock regions inside one zone, then call memmap_init_zone() to do memmap init for each region. E.g, on VMware's system, the memory layout is as below, there are two memory regions in node 2. The current code will mistakenly initialize the whole 1st region [mem 0xab00000000-0xfcffffffff], then do memmap defer to iniatialize only one memmory section on the 2nd region [mem 0x10000000000-0x1033fffffff]. In fact, we only expect to see that there's only one memory section's memmap initialized. That's why more time is costed at the time. [ 0.008842] ACPI: SRAT: Node 0 PXM 0 [mem 0x00000000-0x0009ffff] [ 0.008842] ACPI: SRAT: Node 0 PXM 0 [mem 0x00100000-0xbfffffff] [ 0.008843] ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0x55ffffffff] [ 0.008844] ACPI: SRAT: Node 1 PXM 1 [mem 0x5600000000-0xaaffffffff] [ 0.008844] ACPI: SRAT: Node 2 PXM 2 [mem 0xab00000000-0xfcffffffff] [ 0.008845] ACPI: SRAT: Node 2 PXM 2 [mem 0x10000000000-0x1033fffffff] Now, let's add a parameter 'zone_end_pfn' to memmap_init_zone() to pass down the real zone end pfn so that defer_init() can use it to judge whether defer need be taken in zone wide.

[merged] mm-hugetlb-fix-deadlock-in-hugetlb_cow-error-path.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/hugetlb: fix deadlock in hugetlb_cow error path has been removed from the -mm tree. Its filename was mm-hugetlb-fix-deadlock-in-hugetlb_cow-error-path.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mike Kravetz <mike.kravetz(a)oracle.com> Subject: mm/hugetlb: fix deadlock in hugetlb_cow error path syzbot reported the deadlock here [1]. The issue is in hugetlb cow error handling when there are not enough huge pages for the faulting task which took the original reservation. It is possible that other (child) tasks could have consumed pages associated with the reservation. In this case, we want the task which took the original reservation to succeed. So, we unmap any associated pages in children so that they can be used by the faulting task that owns the reservation. The unmapping code needs to hold i_mmap_rwsem in write mode. However, due to commit c0d0381ade79 ("hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization") we are already holding i_mmap_rwsem in read mode when hugetlb_cow is called. Technically, i_mmap_rwsem does not need to be held in read mode for COW mappings as they can not share pmd's. Modifying the fault code to not take i_mmap_rwsem in read mode for COW (and other non-sharable) mappings is too involved for a stable fix. Instead, we simply drop the hugetlb_fault_mutex and i_mmap_rwsem before unmapping. This is OK as it is technically not needed. They are reacquired after unmapping as expected by calling code. Since this is done in an uncommon error path, the overhead of dropping and reacquiring mutexes is acceptable. While making changes, remove redundant BUG_ON after unmap_ref_private.

[PATCH 4/4] io_uring: cancel requests enqueued as task_work's

by Pavel Begunkov

Currently request cancellations are happening before PF_EXITING is set, so it's allowed to call task_work_run(). Even though it should work as it's not it's safer to remove PF_EXITING checks.

sound

by Christian Labisch

Hello ! I could need your help ... I have tested the new kernel 5.10.3 and sound doesn't work with this version. Seems the new Intel audio drivers are the main reason. What can be done ? Do you have any ideas ? Intel Catpt driver support is new ... This deprecates the previous Haswell SoC audio driver code previously providing the audio capabilities. And I am having a Haswell CPU -> Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06) Regards, Christian

patch "crypto: asym_tpm: correct zero out potential secrets" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled crypto: asym_tpm: correct zero out potential secrets to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-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 f93274ef0fe972c120c96b3207f8fce376231a60 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Date: Fri, 4 Dec 2020 09:01:36 +0100 Subject: crypto: asym_tpm: correct zero out potential secrets The function derive_pub_key() should be calling memzero_explicit() instead of memset() in case the complier decides to optimize away the call to memset() because it "knows" no one is going to touch the memory anymore.

[PATCH 1/2] dm crypt: use GFP_ATOMIC when allocating crypto requests from softirq

Commit 39d42fa96ba1b7d2544db3f8ed5da8fb0d5cb877 made it possible for some code paths in dm-crypt to be executed in softirq context, when the underlying driver processes IO requests in interrupt/softirq context.

[PATCH v2 2/2] dm crypt: do not wait for backlogged crypto request completion in softirq

by Ignat Korchagin

Commit 39d42fa96ba1b7d2544db3f8ed5da8fb0d5cb877 made it possible for some code paths in dm-crypt to be executed in softirq context, when the underlying driver processes IO requests in interrupt/softirq context. When Crypto API backlogs a crypto request, dm-crypt uses wait_for_completion to avoid sending further requests to an already overloaded crypto driver. However, if the code is executing in softirq context, we might get the following stacktrace: [ 210.235213][ C0] BUG: scheduling while atomic: fio/2602/0x00000102 [ 210.236701][ C0] Modules linked in: [ 210.237566][ C0] CPU: 0 PID: 2602 Comm: fio Tainted: G W 5.10.0+ #50 [ 210.239292][ C0] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.0.0 02/06/2015 [ 210.241233][ C0] Call Trace: [ 210.241946][ C0] <IRQ> [ 210.242561][ C0] dump_stack+0x7d/0xa3 [ 210.243466][ C0] __schedule_bug.cold+0xb3/0xc2 [ 210.244539][ C0] __schedule+0x156f/0x20d0 [ 210.245518][ C0] ? io_schedule_timeout+0x140/0x140 [ 210.246660][ C0] schedule+0xd0/0x270 [ 210.247541][ C0] schedule_timeout+0x1fb/0x280 [ 210.248586][ C0] ? usleep_range+0x150/0x150 [ 210.249624][ C0] ? unpoison_range+0x3a/0x60 [ 210.250632][ C0] ? ____kasan_kmalloc.constprop.0+0x82/0xa0 [ 210.251949][ C0] ? unpoison_range+0x3a/0x60 [ 210.252958][ C0] ? __prepare_to_swait+0xa7/0x190 [ 210.254067][ C0] do_wait_for_common+0x2ab/0x370 [ 210.255158][ C0] ? usleep_range+0x150/0x150 [ 210.256192][ C0] ? bit_wait_io_timeout+0x160/0x160 [ 210.257358][ C0] ? blk_update_request+0x757/0x1150 [ 210.258582][ C0] ? _raw_spin_lock_irq+0x82/0xd0 [ 210.259674][ C0] ? _raw_read_unlock_irqrestore+0x30/0x30 [ 210.260917][ C0] wait_for_completion+0x4c/0x90 [ 210.261971][ C0] crypt_convert+0x19a6/0x4c00 [ 210.263033][ C0] ? _raw_spin_lock_irqsave+0x87/0xe0 [ 210.264193][ C0] ? kasan_set_track+0x1c/0x30 [ 210.265191][ C0] ? crypt_iv_tcw_ctr+0x4a0/0x4a0 [ 210.266283][ C0] ? kmem_cache_free+0x104/0x470 [ 210.267363][ C0] ? crypt_endio+0x91/0x180 [ 210.268327][ C0] kcryptd_crypt_read_convert+0x30e/0x420 [ 210.269565][ C0] blk_update_request+0x757/0x1150 [ 210.270563][ C0] blk_mq_end_request+0x4b/0x480 [ 210.271680][ C0] blk_done_softirq+0x21d/0x340 [ 210.272775][ C0] ? _raw_spin_lock+0x81/0xd0 [ 210.273847][ C0] ? blk_mq_stop_hw_queue+0x30/0x30 [ 210.275031][ C0] ? _raw_read_lock_irq+0x40/0x40 [ 210.276182][ C0] __do_softirq+0x190/0x611 [ 210.277203][ C0] ? handle_edge_irq+0x221/0xb60 [ 210.278340][ C0] asm_call_irq_on_stack+0x12/0x20 [ 210.279514][ C0] </IRQ> [ 210.280164][ C0] do_softirq_own_stack+0x37/0x40 [ 210.281281][ C0] irq_exit_rcu+0x110/0x1b0 [ 210.282286][ C0] common_interrupt+0x74/0x120 [ 210.283376][ C0] asm_common_interrupt+0x1e/0x40 [ 210.284496][ C0] RIP: 0010:_aesni_enc1+0x65/0xb0 Fix this by making crypt_convert function reentrant from the point of a single bio and make dm-crypt defer further bio processing to a workqueue, if Crypto API backlogs a request in interrupt context.

[PATCH] drm/panel: ilitek-ili9881c: fix attach failure cleanup

by Icenowy Zheng

When mipi_dsi_attach() fails (e.g. got a -EPROBE_DEFER), the panel should be removed, otherwise a pointer to it will be kept and then lead to use-after-free when DRM panel codes are called (e.g. the panel is probed again).

patch "USB: Gadget: dummy-hcd: Fix shift-out-of-bounds bug" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: Gadget: dummy-hcd: Fix shift-out-of-bounds bug to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-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 c318840fb2a42ce25febc95c4c19357acf1ae5ca Mon Sep 17 00:00:00 2001 From: Alan Stern <stern(a)rowland.harvard.edu> Date: Wed, 30 Dec 2020 11:20:44 -0500 Subject: USB: Gadget: dummy-hcd: Fix shift-out-of-bounds bug The dummy-hcd driver was written under the assumption that all the parameters in URBs sent to its root hub would be valid. With URBs sent from userspace via usbfs, that assumption can be violated. In particular, the driver doesn't fully check the port-feature values stored in the wValue entry of Clear-Port-Feature and Set-Port-Feature requests. Values that are too large can cause the driver to perform an invalid left shift of more than 32 bits. Ironically, two of those left shifts are unnecessary, because they implement Set-Port-Feature requests that hubs are not required to support, according to section 11.24.2.13 of the USB-2.0 spec. This patch adds the appropriate checks for the port feature selector values and removes the unnecessary feature settings. It also rejects requests to set the TEST feature or to set or clear the INDICATOR and C_OVERCURRENT features, as none of these are relevant to dummy-hcd's root-hub emulation.

[PATCH 5.4] fscrypt: remove kernel-internal constants from UAPI header

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> commit 3ceb6543e9cf6ed87cc1fbc6f23ca2db903564cd upstream. [Please apply to 5.4-stable.] There isn't really any valid reason to use __FSCRYPT_MODE_MAX or FSCRYPT_POLICY_FLAGS_VALID in a userspace program. These constants are only meant to be used by the kernel internally, and they are defined in the UAPI header next to the mode numbers and flags only so that kernel developers don't forget to update them when adding new modes or flags. In https://lkml.kernel.org/r/20201005074133.1958633-2-satyat@google.com there was an example of someone wanting to use __FSCRYPT_MODE_MAX in a user program, and it was wrong because the program would have broken if __FSCRYPT_MODE_MAX were ever increased. So having this definition available is harmful. FSCRYPT_POLICY_FLAGS_VALID has the same problem. So, remove these definitions from the UAPI header. Replace FSCRYPT_POLICY_FLAGS_VALID with just listing the valid flags explicitly in the one kernel function that needs it. Move __FSCRYPT_MODE_MAX to fscrypt_private.h, remove the double underscores (which were only present to discourage use by userspace), and add a BUILD_BUG_ON() and comments to (hopefully) ensure it is kept in sync. Keep the old name FS_POLICY_FLAGS_VALID, since it's been around for longer and there's a greater chance that removing it would break source compatibility with some program. Indeed, mtd-utils is using it in an #ifdef, and removing it would introduce compiler warnings (about FS_POLICY_FLAGS_PAD_* being redefined) into the mtd-utils build. However, reduce its value to 0x07 so that it only includes the flags with old names (the ones present before Linux 5.4), and try to make it clear that it's now "frozen" and no new flags should be added to it.

[PATCH 4.14 1/3] mm: memcontrol: eliminate raw access to stat and event counters

by Shaoying Xu

From: Johannes Weiner <hannes(a)cmpxchg.org> commit c9019e9bf42e66d028d70d2da6206cad4dd9250d upstream Replace all raw 'this_cpu_' modifications of the stat and event per-cpu counters with API functions such as mod_memcg_state(). This makes the code easier to read, but is also in preparation for the next patch, which changes the per-cpu implementation of those counters.

[PATCH backport 5.10] io_uring: close a small race gap for files cancel

by Pavel Begunkov

commit dfea9fce29fda6f2f91161677e0e0d9b671bc099 upstream. The purpose of io_uring_cancel_files() is to wait for all requests matching ->files to go/be cancelled. We should first drop files of a request in io_req_drop_files() and only then make it undiscoverable for io_uring_cancel_files. First drop, then delete from list. It's ok to leave req->id->files dangling, because it's not dereferenced by cancellation code, only compared against. It would potentially go to sleep and be awaken by following in io_req_drop_files() wake_up().

[PATCH] md/raid10: initialize r10_bio->read_slot before use.

by Song Liu

From: Kevin Vigor <kvigor(a)gmail.com> In __make_request() a new r10bio is allocated and passed to raid10_read_request(). The read_slot member of the bio is not initialized, and the raid10_read_request() uses it to index an array. This leads to occasional panics.

[PATCH AUTOSEL 4.4 1/5] module: set MODULE_STATE_GOING state when a module fails to load

[PATCH AUTOSEL 4.19 01/10] ARM: 9014/2: Replace string mem* functions for KASan

by Sasha Levin

From: Linus Walleij <linus.walleij(a)linaro.org> [ Upstream commit d6d51a96c7d63b7450860a3037f2d62388286a52 ] Functions like memset()/memmove()/memcpy() do a lot of memory accesses. If a bad pointer is passed to one of these functions it is important to catch this. Compiler instrumentation cannot do this since these functions are written in assembly. KASan replaces these memory functions with instrumented variants. The original functions are declared as weak symbols so that the strong definitions in mm/kasan/kasan.c can replace them. The original functions have aliases with a '__' prefix in their name, so we can call the non-instrumented variant if needed. We must use __memcpy()/__memset() in place of memcpy()/memset() when we copy .data to RAM and when we clear .bss, because kasan_early_init cannot be called before the initialization of .data and .bss. For the kernel compression and EFI libstub's custom string libraries we need a special quirk: even if these are built without KASan enabled, they rely on the global headers for their custom string libraries, which means that e.g. memcpy() will be defined to __memcpy() and we get link failures. Since these implementations are written i C rather than assembly we use e.g. __alias(memcpy) to redirected any users back to the local implementation.

[PATCH] DTS: ARM: gta04: SPI panel chip select is active low

by H. Nikolaus Schaller

With the arrival of commit 2fee9583198eb9 ("spi: dt-bindings: clarify CS behavior for spi-cs-high and gpio descriptors") it was clarified what the proper state for cs-gpios should be, even if the flag is ignored.

[patch 14/16] lib/zlib: fix inflating zlib streams on s390

by Andrew Morton

From: Ilya Leoshkevich <iii(a)linux.ibm.com> Subject: lib/zlib: fix inflating zlib streams on s390 Decompressing zlib streams on s390 fails with "incorrect data check" error. Userspace zlib checks inflate_state.flags in order to byteswap checksums only for zlib streams, and s390 hardware inflate code, which was ported from there, tries to match this behavior. At the same time, kernel zlib does not use inflate_state.flags, so it contains essentially random values. For many use cases either zlib stream is zeroed out or checksum is not used, so this problem is masked, but at least SquashFS is still affected. Fix by always passing a checksum to and from the hardware as is, which matches zlib_inflate()'s expectations.

[patch 06/16] mm: memmap defer init doesn't work as expected

by Andrew Morton

From: Baoquan He <bhe(a)redhat.com> Subject: mm: memmap defer init doesn't work as expected VMware observed a performance regression during memmap init on their platform, and bisected to commit 73a6e474cb376 ("mm: memmap_init: iterate over memblock regions rather that check each PFN") causing it. Before the commit: [0.033176] Normal zone: 1445888 pages used for memmap [0.033176] Normal zone: 89391104 pages, LIFO batch:63 [0.035851] ACPI: PM-Timer IO Port: 0x448 With commit [0.026874] Normal zone: 1445888 pages used for memmap [0.026875] Normal zone: 89391104 pages, LIFO batch:63 [2.028450] ACPI: PM-Timer IO Port: 0x448 The root cause is the current memmap defer init doesn't work as expected. Before, memmap_init_zone() was used to do memmap init of one whole zone, to initialize all low zones of one numa node, but defer memmap init of the last zone in that numa node. However, since commit 73a6e474cb376, function memmap_init() is adapted to iterater over memblock regions inside one zone, then call memmap_init_zone() to do memmap init for each region. E.g, on VMware's system, the memory layout is as below, there are two memory regions in node 2. The current code will mistakenly initialize the whole 1st region [mem 0xab00000000-0xfcffffffff], then do memmap defer to iniatialize only one memmory section on the 2nd region [mem 0x10000000000-0x1033fffffff]. In fact, we only expect to see that there's only one memory section's memmap initialized. That's why more time is costed at the time. [ 0.008842] ACPI: SRAT: Node 0 PXM 0 [mem 0x00000000-0x0009ffff] [ 0.008842] ACPI: SRAT: Node 0 PXM 0 [mem 0x00100000-0xbfffffff] [ 0.008843] ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0x55ffffffff] [ 0.008844] ACPI: SRAT: Node 1 PXM 1 [mem 0x5600000000-0xaaffffffff] [ 0.008844] ACPI: SRAT: Node 2 PXM 2 [mem 0xab00000000-0xfcffffffff] [ 0.008845] ACPI: SRAT: Node 2 PXM 2 [mem 0x10000000000-0x1033fffffff] Now, let's add a parameter 'zone_end_pfn' to memmap_init_zone() to pass down the real zone end pfn so that defer_init() can use it to judge whether defer need be taken in zone wide.

[patch 02/16] mm/hugetlb: fix deadlock in hugetlb_cow error path

by Andrew Morton

From: Mike Kravetz <mike.kravetz(a)oracle.com> Subject: mm/hugetlb: fix deadlock in hugetlb_cow error path syzbot reported the deadlock here [1]. The issue is in hugetlb cow error handling when there are not enough huge pages for the faulting task which took the original reservation. It is possible that other (child) tasks could have consumed pages associated with the reservation. In this case, we want the task which took the original reservation to succeed. So, we unmap any associated pages in children so that they can be used by the faulting task that owns the reservation. The unmapping code needs to hold i_mmap_rwsem in write mode. However, due to commit c0d0381ade79 ("hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization") we are already holding i_mmap_rwsem in read mode when hugetlb_cow is called. Technically, i_mmap_rwsem does not need to be held in read mode for COW mappings as they can not share pmd's. Modifying the fault code to not take i_mmap_rwsem in read mode for COW (and other non-sharable) mappings is too involved for a stable fix. Instead, we simply drop the hugetlb_fault_mutex and i_mmap_rwsem before unmapping. This is OK as it is technically not needed. They are reacquired after unmapping as expected by calling code. Since this is done in an uncommon error path, the overhead of dropping and reacquiring mutexes is acceptable. While making changes, remove redundant BUG_ON after unmap_ref_private.

[PATCH] MIPS: boot: Fix unaligned access with CONFIG_MIPS_RAW_APPENDED_DTB

by Paul Cercueil

The compressed payload is not necesarily 4-byte aligned, at least when compiling with Clang. In that case, the 4-byte value appended to the compressed payload that corresponds to the uncompressed kernel image size must be read using get_unaligned_le(). This fixes Clang-built kernels not booting on MIPS (tested on a Ingenic JZ4770 board). Fixes: b8f54f2cde78 ("MIPS: ZBOOT: copy appended dtb to the end of the kernel") Cc: <stable(a)vger.kernel.org> # v4.7 Signed-off-by: Paul Cercueil <paul(a)crapouillou.net> --- arch/mips/boot/compressed/decompress.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/mips/boot/compressed/decompress.c b/arch/mips/boot/compressed/decompress.c index c61c641674e6..47c07990432b 100644 --- a/arch/mips/boot/compressed/decompress.c +++ b/arch/mips/boot/compressed/decompress.c @@ -117,7 +117,7 @@ void decompress_kernel(unsigned long boot_heap_start) dtb_size = fdt_totalsize((void *)&__appended_dtb); /* last four bytes is always image size in little endian */ - image_size = le32_to_cpup((void *)&__image_end - 4); + image_size = get_unaligned_le32((void *)&__image_end - 4); /* copy dtb to where the booted kernel will expect it */ memcpy((void *)VMLINUX_LOAD_ADDRESS_ULL + image_size, -- 2.29.2

[PATCH] drm/i915/gt: Define guc firmware blob for older Cometlakes

When splitting the Coffeelake define to also identify Cometlakes, I missed the double fw_def for Coffeelake.

[PATCH 4.14 3/3] mm: memcontrol: fix excessive complexity in memory.stat reporting

by Shaoying Xu

From: Johannes Weiner <hannes(a)cmpxchg.org> commit a983b5ebee57209c99f68c8327072f25e0e6e3da upstream We've seen memory.stat reads in top-level cgroups take up to fourteen seconds during a userspace bug that created tens of thousands of ghost cgroups pinned by lingering page cache. Even with a more reasonable number of cgroups, aggregating memory.stat is unnecessarily heavy. The complexity is this: nr_cgroups * nr_stat_items * nr_possible_cpus where the stat items are ~70 at this point. With 128 cgroups and 128 CPUs - decent, not enormous setups - reading the top-level memory.stat has to aggregate over a million per-cpu counters. This doesn't scale. Instead of spreading the source of truth across all CPUs, use the per-cpu counters merely to batch updates to shared atomic counters. This is the same as the per-cpu stocks we use for charging memory to the shared atomic page_counters, and also the way the global vmstat counters are implemented. Vmstat has elaborate spilling thresholds that depend on the number of CPUs, amount of memory, and memory pressure - carefully balancing the cost of counter updates with the amount of per-cpu error. That's because the vmstat counters are system-wide, but also used for decisions inside the kernel (e.g. NR_FREE_PAGES in the allocator). Neither is true for the memory controller. Use the same static batch size we already use for page_counter updates during charging. The per-cpu error in the stats will be 128k, which is an acceptable ratio of cores to memory accounting granularity.

[PATCH 4.14 2/3] mm: memcontrol: implement lruvec stat functions on top of each other

by Shaoying Xu

From: Johannes Weiner <hannes(a)cmpxchg.org> commit 284542656e22c43fdada8c8cc0ca9ede8453eed7 upstream The implementation of the lruvec stat functions and their variants for accounting through a page, or accounting from a preemptible context, are mostly identical and needlessly repetitive.

Secondly the fix won't work well for the very first attempt of the ULPI PHY control registers IO, because after disabling the USB2.0 PHY suspension functionality it will still take some time for the bus to resume from the sleep state if one has been reached before it. So the very first PHY register read/write operation will take more time than the busy-loop provides and the IO timeout error might be returned anyway. Here we suggest to fix the denoted problems in the following way. First of all let's not disable the Suspend USB2.0 HS/FS/LS PHY functionality so to make the controller and the USB2.0 bus more power efficient. Secondly instead of that we'll extend the PHY IO op wait procedure with 1 - 1.2 ms sleep if the PHY suspension is enabled (1ms should be enough as by LPM specification it is at most how long it takes for the USB2.0 bus to resume from L1 (Sleep) state). Finally in case if the USB2.0 PHY suspension functionality has been disabled on the DWC USB3 controller setup procedure we'll compensate the USB bus resume process latency by extending the busy-loop attempts counter.

It's wrong since on different systems the loop will take a different time to complete. So if the system bus and CPU are fast enough to overtake the ULPI bus and the companion PHY reaction, then we'll get to take a false timeout error. Fix this by converting the busy-loop procedure to take the standard bus speed, address value and the registers access mode into account for the busy-loop delay calculation. Here is the way the fix works. It's known that the ULPI bus is clocked with 60MHz signal. In accordance with [1] the ULPI bus protocol is created so to spend 5 and 6 clock periods for immediate register write and read operations respectively, and 6 and 7 clock periods - for the extended register writes and reads. Based on that we can easily pre-calculate the time which will be needed for the controller to perform a requested IO operation. Note we'll still preserve the attempts counter in case if the DWC USB3 controller has got some internals delays.

The doc doesn't say anything about the GUSB2PHYACCn.VStsBsy flag serving for the same purpose. Moreover we've discovered that the VStsBsy flag can be cleared before the VStsDone bit. So using the former as a signal of the PHY control registers completion might be dangerous. Let's have the VStsDone flag utilized instead then.

This fix was not taking into account that in case the quirk XHCI_INTEL_HOST is set, the wakeup time will be calculated and configured differently.

patch "USB: cdc-wdm: Fix use after free in service_outstanding_interrupt()." added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: cdc-wdm: Fix use after free in service_outstanding_interrupt(). to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-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.

Close the race by doing same checks wdm_read() does upon retry. Also, while wdm_read() checks WDM_DISCONNECTING with desc->rlock held, service_interrupt_work() does not hold desc->rlock. Thus, it is possible that usb_submit_urb() is called from service_outstanding_interrupt() from service_interrupt_work() after WDM_DISCONNECTING was set and kill_urbs() from wdm_disconnect() completed. Thus, move kill_urbs() in wdm_disconnect() to after cancel_work_sync() (which makes sure that service_interrupt_work() is no longer running) completed. Although it seems to be safe to dereference desc->intf->dev in service_outstanding_interrupt() even if WDM_DISCONNECTING was already set because desc->rlock or cancel_work_sync() prevents wdm_disconnect() from reaching list_del() before service_outstanding_interrupt() completes, let's not emit error message if WDM_DISCONNECTING is set by wdm_disconnect() while usb_submit_urb() is in progress.

The ndctl "create.sh" test is able to trigger this signature: WARNING: CPU: 34 PID: 9167 at drivers/nvdimm/label.c:1100 __blk_label_update+0x9a3/0xbc0 [libnvdimm] [..] RIP: 0010:__blk_label_update+0x9a3/0xbc0 [libnvdimm] [..] Call Trace: uuid_store+0x21b/0x2f0 [libnvdimm] kernfs_fop_write+0xcf/0x1c0 vfs_write+0xcc/0x380 ksys_write+0x68/0xe0 When allocated capacity for a namespace is renamed (new UUID) the labels with the old UUID need to be deleted. The ndctl behavior to always destroy namespaces on reconfiguration hid this problem. The immediate impact of this bug is limited since block-window-type namespaces only seem to exist in the specification and not in any shipping products. However, the label handling code is being reused for other technologies like CXL region labels, so there is a benefit to making sure both vertical labels sets (block-window) and horizontal label sets (pmem) have a functional reference implementation in libnvdimm.

[PATCH 4.14] mm: memcontrol: fix excessive complexity in memory.stat reporting

by Shaoying Xu

From: Johannes Weiner <hannes(a)cmpxchg.org> [ Upstream commit a983b5ebee57209c99f68c8327072f25e0e6e3da ] We've seen memory.stat reads in top-level cgroups take up to fourteen seconds during a userspace bug that created tens of thousands of ghost cgroups pinned by lingering page cache. Even with a more reasonable number of cgroups, aggregating memory.stat is unnecessarily heavy. The complexity is this: nr_cgroups * nr_stat_items * nr_possible_cpus where the stat items are ~70 at this point. With 128 cgroups and 128 CPUs - decent, not enormous setups - reading the top-level memory.stat has to aggregate over a million per-cpu counters. This doesn't scale. Instead of spreading the source of truth across all CPUs, use the per-cpu counters merely to batch updates to shared atomic counters. This is the same as the per-cpu stocks we use for charging memory to the shared atomic page_counters, and also the way the global vmstat counters are implemented. Vmstat has elaborate spilling thresholds that depend on the number of CPUs, amount of memory, and memory pressure - carefully balancing the cost of counter updates with the amount of per-cpu error. That's because the vmstat counters are system-wide, but also used for decisions inside the kernel (e.g. NR_FREE_PAGES in the allocator). Neither is true for the memory controller. Use the same static batch size we already use for page_counter updates during charging. The per-cpu error in the stats will be 128k, which is an acceptable ratio of cores to memory accounting granularity.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 1c728719a4da6e654afb9cc047164755072ed7c9 Mon Sep 17 00:00:00 2001 From: Pawel Wieczorkiewicz <wipawel(a)amazon.de> Date: Mon, 14 Dec 2020 10:25:57 +0100 Subject: [PATCH] xen-blkback: set ring->xenblkd to NULL after kthread_stop() When xen_blkif_disconnect() is called, the kernel thread behind the block interface is stopped by calling kthread_stop(ring->xenblkd). The ring->xenblkd thread pointer being non-NULL determines if the thread has been already stopped. Normally, the thread's function xen_blkif_schedule() sets the ring->xenblkd to NULL, when the thread's main loop ends. However, when the thread has not been started yet (i.e. wake_up_process() has not been called on it), the xen_blkif_schedule() function would not be called yet. In such case the kthread_stop() call returns -EINTR and the ring->xenblkd remains dangling. When this happens, any consecutive call to xen_blkif_disconnect (for example in frontend_changed() callback) leads to a kernel crash in kthread_stop() (e.g. NULL pointer dereference in exit_creds()). This is XSA-350.

One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp() assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses an array of smaller elements on the stack. As Lars also noted this anti pattern can involve a leak of data to userspace and that indeed can happen here. We close both issues by moving to a suitable structure in the iio_priv() data. This data is allocated with kzalloc() so no data can leak apart from previous readings. The explicit alignment of ts is not necessary in this case but does make the code slightly less fragile so I have included it.

This was done to allow usersapce the opportunity to transition slowly from a 32b address space, and to avoid breaking inherent 32b assumptions of some commands. However, for insert we limited ourselves to 4G-4K, but on verification we allowed the full 4G. This causes some attempts to bind a new buffer to sporadically fail with -ENOSPC, but at other times be bound successfully. commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1 page") suggests that there is a genuine problem with stateless addressing that cannot utilize the last page in 4G and so we purposefully excluded it. This means that the quick pin pass may cause us to utilize a buggy placement.

Instead of trying to fix it again, let's simplify the logic and move the reset bits to a separate work scheduled when one of the queue reports a timeout. v5: - Simplify panfrost_scheduler_stop() (Steven Price) - Always restart the queue in panfrost_scheduler_start() even if the status is corrupted (Steven Price) v4: - Rework the logic to prevent a race between drm_sched_start() (reset work) and drm_sched_job_timedout() (timeout work) - Drop Steven's R-b - Add dma_fence annotation to the panfrost_reset() function (Daniel Vetter) v3: - Replace the atomic_cmpxchg() by an atomic_xchg() (Robin Murphy) - Add Steven's R-b v2: - Use atomic_cmpxchg() to conditionally schedule the reset work (Steven Price) Fixes: 1a11a88cfd9a ("drm/panfrost: Fix job timeout handling") Cc: <stable(a)vger.kernel.org> Signed-off-by: Boris Brezillon <boris.brezillon(a)collabora.com> Reviewed-by: Steven Price <steven.price(a)arm.com> Signed-off-by: Steven Price <steven.price(a)arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201105151704.2010667-1-bori… diff --git a/drivers/gpu/drm/panfrost/panfrost_device.c b/drivers/gpu/drm/panfrost/panfrost_device.c index 1daf9322954a..fbcf5edbe367 100644 --- a/drivers/gpu/drm/panfrost/panfrost_device.c +++ b/drivers/gpu/drm/panfrost/panfrost_device.c @@ -200,7 +200,6 @@ int panfrost_device_init(struct panfrost_device *pfdev) struct resource *res;

The "Check the capability before cred override" comment misleading: user can skip this check by presenting benign flags first and then overwriting them to non-benign flags. Just remove the cred override for now, hoping this doesn't cause a regression. The proper solution is to create a new setxflags i_op (patches are in the works). Xfstests don't show a regression.
