      net/mlx5e/core/en_fs: fix pointer dereference after free in mlx5e_execute_l2_action · 39a4b86f
      Gustavo A. R. Silva authored
      hn is being kfree'd in mlx5e_del_l2_from_hash and then dereferenced
      by accessing hn->ai.addr
      
      Fix this by copying the MAC address into a local variable for its safe use
      in all possible execution paths within function mlx5e_execute_l2_action.

      Obviously, the driver was never designed with this in mind. So let's
      work around the problem by preventing userspace from interacting
      with these interrupts altogether.

      tcp: fix DSACK-based undo on non-duplicate ACK · d09b9e60
      Priyaranjan Jha authored
      Fixes DSACK-based undo when sender is in Open State and
      an ACK advances snd_una.
      
      Example scenario:
      - Sender goes into recovery and makes some spurious rtx.
      - It comes out of recovery and enters into open state.
      - It sends some more packets, let's say 4.
      - The receiver sends an ACK for the first two, but this ACK is lost.
      - The sender receives ack for first two, and DSACK for previous
        spurious rtx.

      l2tp: don't use l2tp_tunnel_find() in l2tp_ip and l2tp_ip6 · 8f7dc9ae
      Guillaume Nault authored
      Using l2tp_tunnel_find() in l2tp_ip_recv() is wrong for two reasons:
      
        * It doesn't take a reference on the returned tunnel, which makes the
          call racy wrt. concurrent tunnel deletion.
      
        * The lookup is only based on the tunnel identifier, so it can return
          a tunnel that doesn't match the packet's addresses or protocol.
      
      For example, a packet sent to an L2TPv3 over IPv6 tunnel can be
      delivered to an L2TPv2 over UDPv4 tunnel. This is worse than a simple
      cross-talk: when delivering the packet to an L2TP over UDP tunnel, the
      corresponding socket is UDP, where ->sk_backlog_rcv() is NULL. Calling
      sk_receive_skb() will then crash the kernel by trying to execute this
      callback.
      
      And l2tp_tunnel_find() isn't even needed here. __l2tp_ip_bind_lookup()
      properly checks the socket binding and connection settings. It was used
      as a fallback mechanism for finding tunnels that didn't have their data
      path registered yet. But it's not limited to this case and can be used
      to replace l2tp_tunnel_find() in the general case.
      
      Fix l2tp_ip6 in the same way.

      Kbuild: don't pass "-C" to preprocessor when processing linker scripts · 5cb0512c
      Linus Torvalds authored
      For some odd historical reason, we preprocessed the linker scripts with
      "-C", which keeps comments around.  That makes no sense, since the
      comments are not meaningful for the build anyway.
      
      And it actually breaks things, since linker scripts can't have C++ style
      "//" comments in them, so keeping comments after preprocessing now
      limits us in odd and surprising ways in our header files for no good
      reason.
      
      The -C option goes back to pre-git and pre-bitkeeper times, but seems to
      have been historically used (along with "-traditional") for some
      odd-ball architectures (ia64, MIPS and SH).  It probably didn't matter
      back then either, but might possibly have been used to minimize the
      difference between the original file and the pre-processed result.
      
      The reason for this may be lost in time, but let's not perpetuate it
      only because we can't remember why we did this crazy thing.
      
      This was triggered by the recent addition of SPDX lines to the source
      tree, where people apparently were confused about why header files
      couldn't use the C++ comment format.

      Mark Rutland authored
      It's possible for a user to deliberately trigger __dump_instr with a
      chosen kernel address.
      
      Let's avoid problems resulting from this by using get_user() rather than
      __get_user(), ensuring that we don't erroneously access kernel memory.
      
      Where we use __dump_instr() on kernel text, we already switch to
      KERNEL_DS, so this shouldn't adversely affect those cases.

      Merge tag 'spdx_identifiers-4.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
      
      Pull initial SPDX identifiers from Greg KH:
       "License cleanup: add SPDX license identifiers to some files
      
        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.

       "This consists of a single fix to a regression to printing individual
        test results to the console. An earlier commit changed it to printing
        just the summary of results, which will negatively impact users that
        rely on console log to look at the individual test failures.
      
        This fix makes it optional to print summary and by default results get
        printed to the console"

      Pull sound fixes from Takashi Iwai:
       "Unfortunately we still have received a significant amount of changes
        at the late stage, but at least all are small and clear fixes.
      
        There are two fixes for ALSA core stuff, yet another timer race fix
        and sequencer lockdep annotation fix. Both are spotted by syzkaller,
        and not too serious but better to paper over quickly.
      
        All other commits are about ASoC drivers, most notably, a revert of
        RT5514 hotword control that was included in 4.14-rc (due to a kind of
        abuse of kctl TLV ABI), together with topology API fixes and other
        device-specific small fixes that should go for stable, too"
