2019-02-11xfs: Introduce XFS_PTAG_VERIFIER_ERROR panic maskMarco Benatto
Currently we have a few PTAGs in place allowing us to transform a filesystem error in a BUG() call. However, we don't have a panic tag for corrupt metadata, so introduce XFS_PTAG_VERIFIER_ERROR so that the administrator can use the fs.xfs.panic_mask sysctl knob to convert any error detected by buffer verifiers into a kernel panic.

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.

2017-10-26xfs: buffer lru reference count error injection tagBrian Foster
XFS uses a fixed reference count for certain types of buffers in the internal LRU cache. These reference counts dictate how aggressively certain buffers are reclaimed vs. others. While the reference counts implements priority across different buffer types, all buffers (other than uncached buffers) are typically cached for at least one reclaim cycle. We've had at least one bug recently that has been hidden by a released buffer sitting around in the LRU. Users hitting the problem were able to reproduce under enough memory pressure to cause aggressive reclaim in a particular window of time. To support future xfstests cases, add an error injection tag to hardcode the buffer reference count to zero. When enabled, this bypasses caching of associated buffers and facilitates test cases that depend on this behavior. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.

2017-08-22xfs: add log item pinning error injection tagBrian Foster
Add an error injection tag to force log items in the AIL to the pinned state. This option can be used by test infrastructure to induce head behind tail conditions. Specifically, this is intended to be used by xfstests to reproduce log recovery problems after failed/corrupted log writes overwrite the last good tail LSN in the log. When enabled, AIL push attempts see log items in the AIL in the pinned state. This stalls metadata writeback and thus prevents the current tail of the log from moving forward. When disabled, subsequent AIL pushes observe the log items in their appropriate state and filesystem operation continues as normal.

2016-08-03xfs: propagate bmap updates to rmapbtDarrick J. Wong
When we map, unmap, or convert an extent in a file's data or attr fork, schedule a respective update in the rmapbt. Previous versions of this patch required a 1:1 correspondence between bmap and rmap, but this is no longer true as we now have ability to make interval queries against the rmapbt. We use the deferred operations code to handle redo operations atomically and deadlock free. This plumbs in all five rmap actions (map, unmap, convert extent, alloc, free); we'll use the first three now for file data, and reflink will want the last two. We also add an error injection site to test log recovery. Finally, we need to fix the bmap shift extent code to adjust the rmaps correctly. Signed-off-by: Darrick J.

In certain cases of inode corruption, the xfs_fs_repair_cmn_err() macro is used to output an extra message in the corruption report. That extra message is "unmount and run xfs_repair", which really applies to any corruption report. Each case that this macro is called (except one) a following call to xfs_corruption_error() is made to optionally dump more information about the error. Hence, move the output of "run xfs_repair" to xfs_corruption_error() so that it is output on all corruption reports. Also, convert the callers of the repair macro that don't call xfs_corruption_error() to call it, hence provide consiѕtent error reporting for all cases where xfs_fs_repair_cmn_err() used to be called.

2011-01-12xfs: prevent NMI timeouts in cmn_errDave Chinner
We currently have a global error message buffer in cmn_err that is protected by a spin lock that disables interrupts. Recently there have been reports of NMI timeouts occurring when the console is being flooded by SCSI error reports due to cmn_err() getting stuck trying to print to the console while holding this lock (i.e. with interrupts disabled). The NMI watchdog is seeing this CPU as non-responding and so is triggering a panic. While the trigger for the reported case is SCSI errors, pretty much anything that spams the kernel log could cause this to occur. Realistically the only reason that we have the intemediate message buffer is to prepend the correct kernel log level prefix to the log message. The only reason we have the lock is to protect the global message buffer and the only reason the message buffer is global is to keep it off the stack. Hence if we can avoid needing a global message buffer we avoid needing the lock, and we can do this with a small amount of cleanup and some preprocessor tricks: 1. clean up xfs_cmn_err() panic mask functionality to avoid needing debug code in xfs_cmn_err() 2. remove the couple of "!" message prefixes that still exist that the existing cmn_err() code steps over. 3. redefine CE_* levels directly to KERN_* 4. redefine cmn_err() and friends to use printk() directly via variable argument length macros. By doing this, we can completely remove the cmn_err() code and the lock that is causing the problems, and rely solely on printk() serialisation to ensure that we don't get garbled messages. A series of followup patches is really needed to clean up all the cmn_err() calls and related messages properly, but that results in a series that is not easily back portable to enterprise kernels. Hence this initial fix is only to address the direct problem in the lowest impact way possible.
