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.

2018-05-30xfs: add helpers to deal with transaction allocation and rollingDarrick J. Wong
For repairs, we need to reserve at least as many blocks as we think we're going to need to rebuild the data structure, and we're going to need some helpers to roll transactions while maintaining locks on the AG headers so that other threads cannot wander into the middle of a repair.

2018-05-15xfs: skip scrub xref if corruption already notedDarrick J. Wong
Don't bother looking for cross-referencing problems if the metadata is already corrupt or we've already found a cross-referencing problem. Since we added a helper function for flags testing, convert existing users to use it. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>

2018-03-23xfs: move inode extent size hint validation to libxfsDarrick J. Wong
Extent size hint validation is used by scrub to decide if there's an error, and it will be used by repair to decide to remove the hint. Since these use the same validation functions, move them to libxfs. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
2018-03-23xfs: remove xfs_buf parameter from inode scrub methodsDarrick J. Wong
Now that we no longer do raw inode buffer scrubbing, the bp parameter is no longer used anywhere we're dealing with an inode, so remove it and all the useless NULL parameters that go with it. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
2018-03-23xfs: inode scrubber shouldn't bother with raw checksDarrick J. Wong
The inode scrubber tries to _iget the inode prior to running checks. If that _iget call fails with corruption errors that's an automatic fail, regardless of whether it was the inode buffer read verifier, the ifork verifier, or the ifork formatter that errored out. Therefore, get rid of the raw mode scrub code because it's not needed. Found by trying to fix some test failures in xfs/379 and xfs/415. Signed-off-by: Darrick J.

2018-01-17xfs: cross-reference reverse-mapping btreeDarrick J. Wong
When scrubbing various btrees, we should cross-reference the records with the reverse mapping btree and ensure that traversing the btree finds the same number of blocks that the rmapbt thinks are owned by that btree.

2018-01-17xfs: fix a few erroneous process_error calls in the scrubbersDarrick J. Wong
There are a few places where we make a libxfs api call on behalf of some object other than the one we're scrubbing but inadvertently call the regular process_error function. When this happens we mark the object corrupt even though it was corruption in /some other/ object that actually produced the -EFSCORRUPTED code. The correct output flag for these situations is SCRUB_OFLAG_XFAIL, not SCRUB_OFLAG_CORRUPT, so fix this now that we also have a helper to set these. Signed-off-by: Darrick J.

2018-01-08xfs: have buffer verifier functions report failing addressDarrick J. Wong

2018-01-08xfs: always grab transaction when scrubbing inodeDarrick J. Wong
Always allocate a transaction for inode scrubbing, even if the _iget fails. This is something that is nice to have now for consistency with the other scrubbers but will become critical when we get to online repair where we'll actually use the transaction + raw buffer read to fix the verifier errors.

2017-11-30xfs: scrub inode mode properlyDarrick J. Wong
Since we've used up all the bits in i_mode, the existing mode check doesn't actually do anything useful. However, we've not used all the bit values in the format portion of i_mode, so we /do/ need to test that for bad values.

2017-11-09xfs: pass inode number to xfs_scrub_ino_set_{preen,warning}Darrick J. Wong
There are two ways to scrub an inode -- calling xfs_iget and checking the raw inode core, or by loading the inode cluster buffer and checking the on-disk contents directly. The second method is only useful if _iget fails the verifiers; when this is the case, sc->ip is NULL and calling the tracepoint will cause a system crash. Therefore, pass the raw inode number directly into the _preen and _warning functions. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Darrick J.
