On some linux distributions, the default link of sh is dash which deoesn't support split array like "${var//,/ }" It's better to force to use bash shell directly.

2017-12-14mm/slab.c: do not hash pointers when debugging slabGeert Uytterhoeven1-13/+10
If CONFIG_DEBUG_SLAB/CONFIG_DEBUG_SLAB_LEAK are enabled, the slab code prints extra debug information when e.g. corruption is detected. This includes pointers, which are not very useful when hashed. Fix this by using %px to print unhashed pointers instead where it makes sense, and by removing the printing of a last user pointer referring to code.

2017-12-14mm/page_alloc.c: avoid excessive IRQ disabled times in free_unref_page_list()Lucas Stach1-0/+11
Since commit 9cca35d42eb6 ("mm, page_alloc: enable/disable IRQs once when freeing a list of pages") we see excessive IRQ disabled times of up to 25ms on an embedded ARM system (tracing overhead included). This is due to graphics buffers being freed back to the system via release_pages(). Graphics buffers can be huge, so it's not hard to hit cases where the list of pages to free has 2048 entries. Disabling IRQs while freeing all those pages is clearly not a good idea. Introduce a batch limit, which allows IRQ servicing once every few pages. The batch count is the same as used in other parts of the MM subsystem when dealing with IRQ disabled regions.

2017-12-14mm/memory.c: mark wp_huge_pmd() inline to prevent build failureGeert Uytterhoeven1-1/+2
With gcc 4.1.2: mm/memory.o: In function `wp_huge_pmd': memory.c:(.text+0x9b4): undefined reference to `do_huge_pmd_wp_page' Interestingly, wp_huge_pmd() is emitted in the assembler output, but never called. Apparently replacing the call to pmd_write() in __handle_mm_fault() by a call to the more complex pmd_access_permitted() reduced the ability of the compiler to remove unused code. Fix this by marking wp_huge_pmd() inline, like was done in commit 91a90140f998 ("mm/memory.c: mark create_huge_pmd() inline to prevent build failure") for a similar problem.

2017-12-14exec: avoid gcc-8 warning for get_task_commArnd Bergmann2-5/+8
gcc-8 warns about using strncpy() with the source size as the limit: fs/exec.c:1223:32: error: argument to 'sizeof' in 'strncpy' call is the same expression as the source; did you mean to use the size of the destination? [-Werror=sizeof-pointer-memaccess] This is indeed slightly suspicious, as it protects us from source arguments without NUL-termination, but does not guarantee that the destination is terminated. This keeps the strncpy() to ensure we have properly padded target buffer, but ensures that we use the correct length, by passing the actual length of the destination buffer as well as adding a build-time check to ensure it is exactly TASK_COMM_LEN. There are only 23 callsites which I all reviewed to ensure this is currently the case. We could get away with doing only the check or passing the right length, but it doesn't hurt to do both.

2017-12-14string.h: workaround for increased stack usageArnd Bergmann1-1/+4
The hardened strlen() function causes rather large stack usage in at least one file in the kernel, in particular when CONFIG_KASAN is enabled: drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init': drivers/media/usb/em28xx/em28xx-dvb.c:2062:1: error: the frame size of 3256 bytes is larger than 204 bytes [-Werror=frame-larger-than=] Analyzing this problem led to the discovery that gcc fails to merge the stack slots for the i2c_board_info[] structures after we strlcpy() into them, due to the 'noreturn' attribute on the source string length check. I reported this as a gcc bug, but it is unlikely to get fixed for gcc-8, since it is relatively easy to work around, and it gets triggered rarely. An earlier workaround I did added an empty inline assembly statement before the call to fortify_panic(), which works surprisingly well, but is really ugly and unintuitive. This is a new approach to the same problem, this time addressing it by not calling the 'extern __real_strnlen()' function for string constants where __builtin_strlen() is a compile-time constant and therefore known to be safe. We do this by checking if the last character in the string is a compile-time constant '\0'. If it is, we can assume that strlen() of the string is also constant. As a side-effect, this should also improve the object code output for any other call of strlen() on a string constant.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux Pull RISC-V fixes from Palmer Dabbelt: "This contains three small fixes: - A fix to a typo in sys_riscv_flush_icache. This only effects error handling, but I think it's a small and obvious enough change that it's sane outside the merge window. - The addition of smp_mb__after_spinlock(), which was recently removed due to an incorrect comment. This is largly a comment change (as there's a big one now), and while it's necessary for complience with the RISC-V memory model the lack of this fence shouldn't manifest as a bug on current implementations. Nonetheless, it still seems saner to have the fence in 4.15. - The removal of some of the HVC_RISCV_SBI driver that snuck into the arch port. This is compile-time dead code in 4.15 (as the driver isn't in yet), and during the review process we found a better way to implement early printk on RISC-V. While this change doesn't do anything, it will make staging our HVC driver easier: without this change the HVC driver we hope to upstream won't build on 4.15 (because the 4.15 arch code would reference a function that no longer exists). I don't think this is the last patch set we'll want for 4.15: I think I'll want to remove some of the first-level irqchip driver that snuck in as well, which will look a lot like the HVC patch here. This is pending some asm-generic cleanup I'm doing that I haven't quite gotten clean enough to send out yet, though, but hopefully it'll be ready by next week (and still OK for that late)" * tag 'riscv-for-linus-4.15-rc4-riscv_fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux: RISC-V: Remove unused CONFIG_HVC_RISCV_SBI code RISC-V: Resurrect smp_mb__after_spinlock() RISC-V: Logical vs Bitwise typo

2017-12-11RISC-V: Remove unused CONFIG_HVC_RISCV_SBI codePalmer Dabbelt1-11/+0
This is code that probably should never have made it into the kernel in the first place: it depends on a driver that hadn't been reviewed yet. During the HVC_SBI_RISCV review process a better way of doing this was suggested, but that means this code is defunct. It's compile-time disabled in 4.15 because the driver isn't in, so I think it's safe to just remove this for now.

The pointer io.io_setup is not initialized and thus it causes crash in try_smi_init when attempting to call new_smi->io.io_setup.

2017-12-11ipmi_si: Fix oops with PCI devicesCorey Minyard1-2/+5
When the IPMI PCI code was split out, some code was consolidated for setting the io_setup field in the io structure. The PCI code needed this set before registration to probe register spacing, though, so restore the old code for that function.

sign_extend32 counts the sign bit parameter from 0, not from 1. So we have to use "11" for 12th bit, not "12". This mistake means we have not allowed negative op and cmp args since commit 30d6e0a4190d ("futex: Remove duplicated code and fix undefined behaviour") till now.

2017-12-08xfs: make iomap_begin functions trim iomaps consistentlyDarrick J. Wong1-1/+1
Historically, the XFS iomap_begin function only returned mappings for exactly the range queried, i.e. it doesn't do XFS_BMAPI_ENTIRE lookups. The current vfs iomap consumers are only set up to deal with trimmed mappings. xfs_xattr_iomap_begin does BMAPI_ENTIRE lookups, which is inconsistent with the current iomap usage. Remove the flag so that both iomap_begin functions behave the same way. FWIW this also fixes a behavioral regression in xattr FIEMAP that was introduced in 4.8 wherein attr fork extents are no longer trimmed like they used to be. Signed-off-by: Darrick J.

2017-12-08xfs: remove "no-allocation" reservations for file creationsChristoph Hellwig6-51/+14
If we create a new file we will need an inode, and usually some metadata in the parent direction. Aiming for everything to go well despite the lack of a reservation leads to dirty transactions cancelled under a heavy create/delete load. This patch removes those nospace transactions, which will lead to slightly earlier ENOSPC on some workloads, but instead prevent file system shutdowns due to cancelling dirty transactions for others. A customer could observe assertations failures and shutdowns due to cancelation of dirty transactions during heavy NFS workloads as shown below: 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728125] XFS: Assertion failed: error != -ENOSPC, file: fs/xfs/xfs_inode.c, line: 1262 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728222] Call Trace: 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728246] [<ffffffff81795daf>] dump_stack+0x63/0x81 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728262] [<ffffffff810a1a5a>] warn_slowpath_common+0x8a/0xc0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728264] [<ffffffff810a1b8a>] warn_slowpath_null+0x1a/0x20 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728285] [<ffffffffa01bf403>] asswarn+0x33/0x40 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728308] [<ffffffffa01bb07e>] xfs_create+0x7be/0x7d0 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728329] [<ffffffffa01b6ffb>] xfs_generic_create+0x1fb/0x2e0 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728348] [<ffffffffa01b7114>] xfs_vn_mknod+0x14/0x20 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728366] [<ffffffffa01b7153>] xfs_vn_create+0x13/0x20 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728380] [<ffffffff81231de5>] vfs_create+0xd5/0x140 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728390] [<ffffffffa045ddb9>] do_nfsd_create+0x499/0x610 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728396] [<ffffffffa0465fa5>] nfsd3_proc_create+0x135/0x210 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728401] [<ffffffffa04561e3>] nfsd_dispatch+0xc3/0x210 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728416] [<ffffffffa03bfa43>] svc_process_common+0x453/0x6f0 [sunrpc] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728423] [<ffffffffa03bfdf3>] svc_process+0x113/0x1f0 [sunrpc] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728427] [<ffffffffa0455bcf>] nfsd+0x10f/0x180 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728432] [<ffffffffa0455ac0>] ? nfsd_destroy+0x80/0x80 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728438] [<ffffffff810c0d58>] kthread+0xd8/0xf0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728441] [<ffffffff810c0c80>] ? kthread_create_on_node+0x1b0/0x1b0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728451] [<ffffffff8179d962>] ret_from_fork+0x42/0x70 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728453] [<ffffffff810c0c80>] ? kthread_create_on_node+0x1b0/0x1b0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728454] ---[ end trace f9822c842fec81d4 ]--- 2017-05-30 21:17:06 kernel: ALERT: [ 2670.728477] XFS (sdb): Internal error xfs_trans_cancel at line 983 of file fs/xfs/xfs_trans.c.
