2018-07-09block: Make struct request_queue smaller for CONFIG_BLK_DEV_ZONED=nBart Van Assche6-15/+44
Exclude zoned block device members from struct request_queue for CONFIG_BLK_DEV_ZONED == n. Avoid breaking the build by only building the code that uses these struct request_queue members if CONFIG_BLK_DEV_ZONED != n.

2018-07-09block: Inline blk_queue_nr_zones()Bart Van Assche2-6/+1

2018-07-09block: Remove bdev_nr_zones()Bart Van Assche1-9/+0

2018-07-09include/uapi/linux/blkzoned.h: Remove a superfluous __packed directiveBart Van Assche1-1/+1
Using the __packed directive for a structure that does not need it is wrong because it makes gcc generate suboptimal code on some architectures. Hence remove the __packed directive from the blk_zone_report structure definition. See also http://digitalvampire.org/blog/index.php/2006/07/31/why-you-shouldnt-use-__attribute__packed/.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler fixes from Thomas Gleixner: - The hopefully final fix for the reported race problems in kthread_parkme(). The previous attempt still left a hole and was partially wrong. - Plug a race in the remote tick mechanism which triggers a warning about updates not being done correctly. That's a false positive if the race condition is hit as the remote CPU is idle. Plug it by checking the condition again when holding run queue lock. - Fix a bug in the utilization estimation of a run queue which causes the estimation to be 0 when a run queue is throttled. - Advance the global expiration of the period timer when the timer is restarted after a idle period. Otherwise the expiry time is stale and the timer fires prematurely. - Cure the drift between the bandwidth timer and the runqueue accounting, which leads to bogus throttling of runqueues - Place the call to cpufreq_update_util() correctly so the function will observe the correct number of running RT tasks and not a stale one. * 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: kthread, sched/core: Fix kthread_parkme() (again...) sched/util_est: Fix util_est_dequeue() for throttled cfs_rq sched/fair: Advance global expiration when period timer is restarted sched/fair: Fix bandwidth timer clock drift condition sched/rt: Fix call to cpufreq_update_util() sched/nohz: Skip remote tick on idle task entirely

2018-07-05Fix up non-directory creation in SGID directoriesLinus Torvalds1-0/+6
sgid directories have special semantics, making newly created files in the directory belong to the group of the directory, and newly created subdirectories will also become sgid. This is historically used for group-shared directories.

2018-07-05cifs: Fix stack out-of-bounds in smb{2,3}_create_lease_buf()Stefano Brivio5-21/+14
smb{2,3}_create_lease_buf() store a lease key in the lease context for later usage on a lease break. In most paths, the key is currently sourced from data that happens to be on the stack near local variables for oplock in SMB2_open() callers, e.g. from open_shroot(), whereas smb2_open_file() properly allocates space on its stack for it. The address of those local variables holding the oplock is then passed to create_lease_buf handlers via SMB2_open(), and 16 bytes near oplock are used. This causes a stack out-of-bounds access as reported by KASAN on SMB2.1 and SMB3 mounts (first out-of-bounds access is shown here): [ 111.528823] BUG: KASAN: stack-out-of-bounds in smb3_create_lease_buf+0x399/0x3b0 [cifs] [ 111.530815] Read of size 8 at addr ffff88010829f249 by task mount.cifs/985 [ 111.532838] CPU: 3 PID: 985 Comm: mount.cifs Not tainted 4.18.0-rc3+ #91 [ 111.534656] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1 04/01/2014 [ 111.536838] Call Trace: [ 111.537528] dump_stack+0xc2/0x16b [ 111.540890] print_address_description+0x6a/0x270 [ 111.542185] kasan_report+0x258/0x380 [ 111.544701] smb3_create_lease_buf+0x399/0x3b0 [cifs] [ 111.546134] SMB2_open+0x1ef8/0x4b70 [cifs] [ 111.575883] open_shroot+0x339/0x550 [cifs] [ 111.591969] smb3_qfs_tcon+0x32c/0x1e60 [cifs] [ 111.617405] cifs_mount+0x4f3/0x2fc0 [cifs] [ 111.674332] cifs_smb3_do_mount+0x263/0xf10 [cifs] [ 111.677915] mount_fs+0x55/0x2b0 [ 111.679504] vfs_kern_mount.part.22+0xaa/0x430 [ 111.684511] do_mount+0xc40/0x2660 [ 111.698301] ksys_mount+0x80/0xd0 [ 111.701541] do_syscall_64+0x14e/0x4b0 [ 111.711807] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 111.713665] RIP: 0033:0x7f372385b5fa [ 111.715311] Code: 48 8b 0d 99 78 2c 00 f7 d8 64 89 01 48 83 c8 ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 49 89 ca b8 a5 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 66 78 2c 00 f7 d8 64 89 01 48 [ 111.720330] RSP: 002b:00007ffff27049d8 EFLAGS: 00000206 ORIG_RAX: 00000000000000a5 [ 111.722601] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f372385b5fa [ 111.724842] RDX: 000055c2ecdc73b2 RSI: 000055c2ecdc73f9 RDI: 00007ffff270580f [ 111.727083] RBP: 00007ffff2705804 R08: 000055c2ee976060 R09: 0000000000001000 [ 111.729319] R10: 0000000000000000 R11: 0000000000000206 R12: 00007f3723f4d000 [ 111.731615] R13: 000055c2ee976060 R14: 00007f3723f4f90f R15: 0000000000000000 [ 111.735448] The buggy address belongs to the page: [ 111.737420] page:ffffea000420a7c0 count:0 mapcount:0 mapping:0000000000000000 index:0x0 [ 111.739890] flags: 0x17ffffc0000000() [ 111.741750] raw: 0017ffffc0000000 0000000000000000 dead000000000200 0000000000000000 [ 111.744216] raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000 [ 111.746679] page dumped because: kasan: bad access detected [ 111.750482] Memory state around the buggy address: [ 111.752562] ffff88010829f100: 00 f2 f2 f2 f2 f2 f2 f2 00 00 00 00 00 00 00 00 [ 111.754991] ffff88010829f180: 00 00 f2 f2 00 00 00 00 00 00 00 00 00 00 00 00 [ 111.757401] >ffff88010829f200: 00 00 00 00 00 f1 f1 f1 f1 01 f2 f2 f2 f2 f2 f2 [ 111.759801] ^ [ 111.762034] ffff88010829f280: f2 02 f2 f2 f2 f2 f2 f2 f2 00 00 00 00 00 00 00 [ 111.764486] ffff88010829f300: f2 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 111.766913] ================================================================== Lease keys are however already generated and stored in fid data on open and create paths: pass them down to the lease context creation handlers and use them.

2018-07-05cifs: Fix infinite loop when using hard mount optionPaulo Alcantara2-8/+20
For every request we send, whether it is SMB1 or SMB2+, we attempt to reconnect tcon (cifs_reconnect_tcon or smb2_reconnect) before carrying out the request. So, while server->tcpStatus != CifsNeedReconnect, we wait for the reconnection to succeed on wait_event_interruptible_timeout(). If it returns, that means that either the condition was evaluated to true, or timeout elapsed, or it was interrupted by a signal. Since we're not handling the case where the process woke up due to a received signal (-ERESTARTSYS), the next call to wait_event_interruptible_timeout() will _always_ fail and we end up looping forever inside either cifs_reconnect_tcon() or smb2_reconnect(). Here's an example of how to trigger that: $ mount.cifs //foo/share /mnt/test -o username=foo,password=foo,vers=1.0,hard (break connection to server before executing bellow cmd) $ stat -f /mnt/test & sleep 140 [1] 2511 $ ps -aux -q 2511 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2511 0.0 0.0 12892 1008 pts/0 S 12:24 0:00 stat -f /mnt/test $ kill -9 2511 (wait for a while; process is stuck in the kernel) $ ps -aux -q 2511 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2511 83.2 0.0 12892 1008 pts/0 R 12:24 30:01 stat -f /mnt/test By using 'hard' mount point means that cifs.ko will keep retrying indefinitely, however we must allow the process to be killed otherwise it would hang the system.

2018-07-05cifs: Fix use after free of a mid_q_entryLars Persson7-2/+29
With protocol version 2.0 mounts we have seen crashes with corrupt mid entries. Either the server->pending_mid_q list becomes corrupt with a cyclic reference in one element or a mid object fetched by the demultiplexer thread becomes overwritten during use. Code review identified a race between the demultiplexer thread and the request issuing thread. The demultiplexer thread seems to be written with the assumption that it is the sole user of the mid object until it calls the mid callback which either wakes the issuer task or deletes the mid. This assumption is not true because the issuer task can be woken up earlier by a signal. If the demultiplexer thread has proceeded as far as setting the mid_state to MID_RESPONSE_RECEIVED then the issuer thread will happily end up calling cifs_delete_mid while the demultiplexer thread still is using the mid object. Inserting a delay in the cifs demultiplexer thread widens the race window and makes reproduction of the race very easy: if (server->large_buf) buf = server->bigbuf; + usleep_range(500, 4000); server->lstrp = jiffies; To resolve this I think the proper solution involves putting a reference count on the mid object. This patch makes sure that the demultiplexer thread holds a reference until it has finished processing the transaction.

2018-07-05autofs: rename 'autofs' module back to 'autofs4'Linus Torvalds2-3/+3
It turns out that systemd has a bug: it wants to load the autofs module early because of some initialization ordering with udev, and it doesn't do that correctly. Everywhere else it does the proper "look up module name" that does the proper alias resolution, but in that early code, it just uses a hardcoded "autofs4" for the module name. The result of that is that as of commit a2225d931f75 ("autofs: remove left-over autofs4 stubs"), you get systemd[1]: Failed to insert module 'autofs4': No such file or directory in the system logs, and a lack of module loading. All this despite the fact that we had very clearly marked 'autofs4' as an alias for this module. What's so ridiculous about this is that literally everything else does the module alias handling correctly, including really old versions of systemd (that just used 'modprobe' to do this), and even all the other systemd module loading code. Only that special systemd early module load code is broken, hardcoding the module names for not just 'autofs4', but also "ipv6", "unix", "ip_tables" and "virtio_rng". Very annoying. Instead of creating an _additional_ separate compatibility 'autofs4' module, just rely on the fact that everybody else gets this right, and just call the module 'autofs4' for compatibility reasons, with 'autofs' as the alias name. That will allow the systemd people to fix their bugs, adding the proper alias handling, and maybe even fix the name of the module to be just "autofs" (so that they can _test_ the alias handling). And eventually, we can revert this silly compatibility hack. See also https://github.com/systemd/systemd/issues/9501 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902946 for the systemd bug reports upstream and in the Debian bug tracker respectively.

2018-07-05arm64: remove no-op -p linker flagGreg Hackmann1-1/+1
Linking the ARM64 defconfig kernel with LLVM lld fails with the error: ld.lld: error: unknown argument: -p Makefile:1015: recipe for target 'vmlinux' failed Without this flag, the ARM64 defconfig kernel successfully links with lld and boots on Dragonboard 410c. After digging through binutils source and changelogs, it turns out that -p is only relevant to ancient binutils installations targeting 32-bit ARM. binutils accepts -p for AArch64 too, but it's always been undocumented and silently ignored. A comment in ld/emultempl/aarch64elf.em explains that it's "Only here for backwards compatibility". Since this flag is a no-op on ARM64, we can safely drop it.
