2018-06-07ubifs, xattr: remove misguided quota flagsWang Shilong
Originally, Yang Dongsheng added quota support for ubifs, but it turned out upstream won't accept it. Since ubifs don't touch any quota code, S_NOQUOTA flag is misguided here, and currently it is mainly used to avoid recursion for system quota files. Let's make things clearly and remove unnecessary and misguied quota flags here.

regulator: fixed/gpio: Revert GPIO descriptor changes due to platform breakage Commit 6059577cb28 "regulator: fixed: Convert to use GPIO descriptor only" broke at least the ams-delta platform since the lookup tables added to the board files use the function name "enable" while the driver uses NULL causing the regulator to not acquire and control the enable GPIOs.

2018-06-07block: always set partition number to '0' in blk_partition_remap()Hannes Reinecke
blk_partition_remap() will only clear bi_partno if an actual remapping has happened. But flush request et al don't have an actual size, so the remapping doesn't happen and bi_partno is never cleared. So for stacked devices blk_partition_remap() will be called on each level. If (as is the case for native nvme multipathing) one of the lower-level devices do _not_support partitioning a spurious I/O error is generated.

2018-06-07Btrfs: fiemap: pass correct bytenr when fm_extent_count is zeroRobbie Ko
[BUG] fm_mapped_extents is not correct when fm_extent_count is 0 Like: # mount /dev/vdb5 /mnt/btrfs # dd if=/dev/zero bs=16K count=4 oflag=dsync of=/mnt/btrfs/file # xfs_io -c "fiemap -v" /mnt/btrfs/file /mnt/btrfs/file: EXT: FILE-OFFSET BLOCK-RANGE TOTAL FLAGS 0: [0..127]: 25088..25215 128 0x1 When user space wants to get the number of file extents, set fm_extent_count to 0 to run fiemap and then read fm_mapped_extents. In the above example, fiemap will return with fm_mapped_extents set to 4, but it should be 1 since there's only one entry in the output. [REASON] The problem seems to be that disko is only set if fieinfo->fi_extents_max is set. And this member is initialized, in the generic ioctl_fiemap function, to the value of used-passed fm_extent_count. So when the user passes 0 then fi_extent_max is also set to zero and this causes btrfs to not initialize disko at all. Eventually this leads emit_fiemap_extent being called with a bogus 'phys' argument preventing proper fiemap entries merging. [FIX] Move the disko initialization earlier in extent_fiemap making it independent of user-passed arguments, allowing emit_fiemap_extent to properly handle consecutive extent entries.

2018-06-06xfs: fix string handling in label get/set functionsArnd Bergmann
[sandeen: fix subject, avoid copy-out of uninit data in getlabel] gcc-8 reports two warnings for the newly added getlabel/setlabel code: fs/xfs/xfs_ioctl.c: In function 'xfs_ioc_getlabel': fs/xfs/xfs_ioctl.c:1822:38: 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] strncpy(label, sbp->sb_fname, sizeof(sbp->sb_fname)); ^ In function 'strncpy', inlined from 'xfs_ioc_setlabel' at /git/arm-soc/fs/xfs/xfs_ioctl.c:1863:2, inlined from 'xfs_file_ioctl' at /git/arm-soc/fs/xfs/xfs_ioctl.c:1918:10: include/linux/string.h:254:9: error: '__builtin_strncpy' output may be truncated copying 12 bytes from a string of length 12 [-Werror=stringop-truncation] return __builtin_strncpy(p, q, size); In both cases, part of the problem is that one of the strncpy() arguments is a fixed-length character array with zero-padding rather than a zero-terminated string. In the first one case, we also get an odd warning about sizeof-pointer-memaccess, which doesn't seem right (the sizeof is for an array that happens to be the same as the second strncpy argument). To work around the bogus warning, I use a plain 'XFSLABEL_MAX' for the strncpy() length when copying the label in getlabel. For setlabel(), using memcpy() with the correct length that is already known avoids the second warning and is slightly simpler. In a related issue, it appears that we accidentally skip the trailing \0 when copying a 12-character label back to user space in getlabel(). Using the correct sizeof() argument here copies the extra character.

2018-06-06xfs: convert to SPDX license tagsDave Chinner
Remove the verbose license text from XFS files and replace them with SPDX tags. This does not change the license of any of the code, merely refers to the common, up-to-date license files in LICENSES/ This change was mostly scripted. fs/xfs/Makefile and fs/xfs/libxfs/xfs_fs.h were modified by hand, the rest were detected and modified by the following command: for f in `git grep -l "GNU General" fs/xfs/` ; do echo $f cat $f | awk -f hdr.awk > $f.new mv -f $f.new $f done And the hdr.awk script that did the modification (including detecting the difference between GPL-2.0 and GPL-2.0+ licenses) is as follows: $ cat hdr.awk BEGIN { hdr = 1.0 tag = "GPL-2.0" str = "" } /^ \* This program is free software/ { hdr = 2.0; next } /any later version./ { tag = "GPL-2.0+" next } /^ \*\// { if (hdr > 0.0) { print "// SPDX-License-Identifier: " tag print str print $0 str="" hdr = 0.0 next } print $0 next } /^ \* / { if (hdr > 1.0) next if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 next } /^ \*/ { if (hdr > 0.0) next print $0 next } // { if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 } END { } $ Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.
