      vfs: change inode times to use struct timespec64 · 95582b00
      Deepa Dinamani 提交于
      struct timespec is not y2038 safe. Transition vfs to use
      y2038 safe struct timespec64 instead.
      
      The change was made with the help of the following cocinelle
      script. This catches about 80% of the changes.
      All the header file and logic changes are included in the
      first 5 rules. The rest are trivial substitutions.
      I avoid changing any of the function signatures or any other
      filesystem specific data structures to keep the patch simple
      for review.
      
      The script can be a little shorter by combining different cases.
      But, this version was sufficient for my usecase.

      License cleanup: add SPDX GPL-2.0 license identifier to files with no license · b2441318
      Greg Kroah-Hartman 提交于
      Many source files in the tree are missing licensing information, which
      makes it harder for compliance tools to determine the correct license.
      
      By default all files without license information are under the default
      license of the kernel, which is GPL version 2.
      
      Update the files which contain no license information with the 'GPL-2.0'
      SPDX license identifier.  The SPDX identifier is a legally binding
      shorthand, which can be used instead of the full boiler plate text.
      
      This patch is based on work done by Thomas Gleixner and Kate Stewart and
      Philippe Ombredanne.
      
      How this work was done:
      
      Patches were generated and checked against linux-4.14-rc6 for a subset of
      the use cases:
       - file had no licensing information it it.
       - file was a */uapi/* one with no licensing information in it,
       - file was a */uapi/* one with existing licensing information,
      
      Further patches will be generated in subsequent months to fix up cases
      where non-standard license headers were used, and references to license
      had to be inferred by heuristics based on keywords.
      
      The analysis to determine which SPDX License Identifier to be applied to
      a file was done in a spreadsheet of side by side results from of the
      output of two independent scanners (ScanCode & Windriver) producing SPDX
      tag:value files created by Philippe Ombredanne.  Philippe prepared the
      base worksheet, and did an initial spot review of a few 1000 files.
      
      The 4.13 kernel was the starting point of the analysis with 60,537 files
      assessed.  Kate Stewart did a file by file comparison of the scanner
      results in the spreadsheet to determine which SPDX license identifier(s)
      to be applied to the file. She confirmed any determination that was not
      immediately clear with lawyers working with the Linux Foundation.
      
      Criteria used to select files for SPDX license identifier tagging was:
       - Files considered eligible had to be source code files.
       - Make and config files were included as candidates if they contained >5
         lines of source
       - File already had some variant of a license header in it (even if <5
         lines).
      
      All documentation files were explicitly excluded.
      
      The following heuristics were used to determine which SPDX license
      identifiers to apply.
      
       - when both scanners couldn't find any license traces, file was
         considered to have no license information in it, and the top level
         COPYING file license applied.
      
         For non */uapi/* files that summary was:
      
         SPDX license identifier                            # files
         ---------------------------------------------------|-------
         GPL-2.0                                              11139
      
         and resulted in the first patch in this series.
      
         If that file was a */uapi/* path one, it was "GPL-2.0 WITH
         Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:
      
         SPDX license identifier                            # files
         ---------------------------------------------------|-------
         GPL-2.0 WITH Linux-syscall-note                        930
      
         and resulted in the second patch in this series.
      
       - if a file had some form of licensing information in it, and was one
         of the */uapi/* ones, it was denoted with the Linux-syscall-note if
         any GPL family license was found in the file or had no licensing in
         it (per prior point).  Results summary:
      
         SPDX license identifier                            # files
         ---------------------------------------------------|------
         GPL-2.0 WITH Linux-syscall-note                       270
         GPL-2.0+ WITH Linux-syscall-note                      169
         ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
         ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
         LGPL-2.1+ WITH Linux-syscall-note                      15
         GPL-1.0+ WITH Linux-syscall-note                       14
         ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
         LGPL-2.0+ WITH Linux-syscall-note                       4
         LGPL-2.1 WITH Linux-syscall-note                        3
         ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
         ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1
      
         and that resulted in the third patch in this series.
      
       - when the two scanners agreed on the detected license(s), that became
         the concluded license(s).
      
       - when there was disagreement between the two scanners (one detected a
         license but the other didn't, or they both detected different
         licenses) a manual inspection of the file occurred.
      
       - In most cases a manual inspection of the information in the file
         resulted in a clear resolution of the license that should apply (and
         which scanner probably needed to revisit its heuristics).
      
       - When it was not immediately clear, the license identifier was
         confirmed with lawyers working with the Linux Foundation.
      
       - If there was any question as to the appropriate license identifier,
         the file was flagged for further research and to be revisited later
         in time.
      
      In total, over 70 hours of logged manual review was done on the
      spreadsheet to determine the SPDX license identifiers to apply to the
      source files by Kate, Philippe, Thomas and, in some cases, confirmation
      by lawyers working with the Linux Foundation.
      
      Kate also obtained a third independent scan of the 4.13 code base from
      FOSSology, and compared selected files where the other two scanners
      disagreed against that SPDX file, to see if there was new insights.  The
      Windriver scanner is based on an older version of FOSSology in part, so
      they are related.
      
      Thomas did random spot checks in about 500 files from the spreadsheets
      for the uapi headers and agreed with SPDX license identifier in the
      files he inspected. For the non-uapi files Thomas did random spot checks
      in about 15000 files.
      
      In initial set of patches against 4.14-rc6, 3 files were found to have
      copy/paste license identifier errors, and have been fixed to reflect the
      correct identifier.
      
      Additionally Philippe spent 10 hours this week doing a detailed manual
      inspection and review of the 12,461 patched files from the initial patch
      version early this week with:
       - a full scancode scan run, collecting the matched texts, detected
         license ids and scores
       - reviewing anything where there was a license detected (about 500+
         files) to ensure that the applied SPDX license was correct
       - reviewing anything where there was no detection but the patch license
         was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
         SPDX license was correct
      
      This produced a worksheet with 20 files needing minor correction.  This
      worksheet was then exported into 3 different .csv files for the
      different types of files to be modified.
      
      These .csv files were then reviewed by Greg.  Thomas wrote a script to
      parse the csv files and add the proper SPDX tag to the file, in the
      format that the file expected.  This script was further refined by Greg
      based on the output to detect more types of files automatically and to
      distinguish between header and source .c files (which need different
      comment types.)  Finally Greg ran the script using the .csv files to
      generate the patches.

      nfs: allow blocking locks to be awoken by lock callbacks · a1d617d8
      Jeff Layton 提交于
      Add a waitqueue head to the client structure. Have clients set a wait
      on that queue prior to requesting a lock from the server. If the lock
      is blocked, then we can use that to wait for wakeups.
      
      Note that we do need to do this "manually" since we need to set the
      wait on the waitqueue prior to requesting the lock, but requesting a
      lock can involve activities that can block.
      
      However, only do that for NFSv4.1 locks, either by compiling out
      all of the waitqueue handling when CONFIG_NFS_V4_1 is disabled, or
      skipping all of it at runtime if we're dealing with v4.0, or v4.1
      servers that don't send lock callbacks.
      
      Note too that even when we expect to get a lock callback, RFC5661
      section 20.11.4 is pretty clear that we still need to poll for them,
      so we do still sleep on a timeout. We do however always poll at the
      longest interval in that case.

      pNFS: Fix CB_LAYOUTRECALL stateid verification · 793b7fe5
      Trond Myklebust 提交于
      We want to evaluate in this order:
      
      If the client holds no layout for this inode, then return
      NFS4ERR_NOMATCHING_LAYOUT; it probably forgot the layout.
      
      If the client finds the inode among the list of layouts, but the corresponding
      stateid has not yet been initialised, then return NFS4ERR_DELAY to ask the
      server to retry once the outstanding LAYOUTGET is complete.
      
      If the current layout stateid's "other" field does not match the recalled
      stateid, return NFS4ERR_BAD_STATEID.
      
      If already processing a layout recall with a newer stateid, return
      NFS4ERR_OLD_STATEID. This can only happens for servers that are
      non-compliant with the NFSv4.1 protocol.
      
      If already processing a layout recall with an older stateid, return
      NFS4ERR_DELAY to ask the server to retry once the outstanding
      LAYOUTRETURN is complete. Again, this is technically incompliant with
      the NFSv4.1 protocol.
      
      If the current layout sequence id is newer than the recalled stateid's
      sequence id, return NFS4ERR_OLD_STATEID. This too implies protocol
      non-compliance.
      
      If the current layout sequence id is older than the recalled stateid's
      sequence id+1, return NFS4ERR_DELAY.

      Jeff Layton 提交于
      LAYOUTRETURN is "special" in that servers and clients are expected to
      work with old stateids. When the client sends a LAYOUTRETURN with an old
      stateid in it then the server is expected to only tear down layout
      segments that were present when that seqid was current. Ensure that the
      client handles its accounting accordingly.
