      bnx2x: Use NETIF_F_GRO_HW. · 3c3def5f
      Michael Chan 提交于
      Advertise NETIF_F_GRO_HW and turn on TPA_MODE_GRO when NETIF_F_GRO_HW
      is set.  Disable NETIF_F_GRO_HW in bnx2x_fix_features() if the MTU
      does not support TPA_MODE_GRO or GRO is not set.  bnx2x_change_mtu() also
      needs to disable NETIF_F_GRO_HW if the MTU does not support it.
      
      Original parameter disable_tpa will continue to disable LRO and GRO_HW.
      
      Preserve the original behavior of enabling LRO by default.  User has
      to run ethtool -K to explicitly enable GRO_HW.

      bnxt_en: Use NETIF_F_GRO_HW. · 1054aee8
      Michael Chan 提交于
      Advertise NETIF_F_GRO_HW in hw_features if hardware GRO is supported.
      In bnxt_fix_features(), disable GRO_HW and LRO if current hardware
      configuration does not allow it.  GRO_HW depends on GRO.  GRO_HW is
      also mutually exclusive with LRO.  XDP setup will now rely on
      bnxt_fix_features() to turn off aggregation.  During chip init, turn on
      or off hardware GRO based on NETIF_F_GRO_HW in features flag.

      tg3: Fix rx hang on MTU change with 5717/5719 · 748a240c
      Brian King 提交于
      This fixes a hang issue seen when changing the MTU size from 1500 MTU
      to 9000 MTU on both 5717 and 5719 chips. In discussion with Broadcom,
      they've indicated that these chipsets have the same phy as the 57766
      chipset, so the same workarounds apply. This has been tested by IBM
      on both Power 8 and Power 9 systems as well as by Broadcom on x86
      hardware and has been confirmed to resolve the hang issue.

      rhashtable: Change rhashtable_walk_start to return void · 97a6ec4a
      Tom Herbert 提交于
      Most callers of rhashtable_walk_start don't care about a resize event
      which is indicated by a return value of -EAGAIN. So calls to
      rhashtable_walk_start are wrapped wih code to ignore -EAGAIN. Something
      like this is common:
      
             ret = rhashtable_walk_start(rhiter);
             if (ret && ret != -EAGAIN)
                     goto out;
      
      Since zero and -EAGAIN are the only possible return values from the
      function this check is pointless. The condition never evaluates to true.
      
      This patch changes rhashtable_walk_start to return void. This simplifies
      code for the callers that ignore -EAGAIN. For the few cases where the
      caller cares about the resize event, particularly where the table can be
      walked in mulitple parts for netlink or seq file dump, the function
      rhashtable_walk_start_check has been added that returns -EAGAIN on a
      resize event.

      This happens because we increment rx_pkts on -ENOMEM and -EIO, resulting

      treewide: setup_timer() -> timer_setup() · e99e88a9
      Kees Cook 提交于
      This converts all remaining cases of the old setup_timer() API into using
      timer_setup(), where the callback argument is the structure already
      holding the struct timer_list. These should have no behavioral changes,
      since they just change which pointer is passed into the callback with
      the same available pointers after conversion. It handles the following
      examples, in addition to some other variations.
      
      Casting from unsigned long:
      
          void my_callback(unsigned long data)
          {
              struct something *ptr = (struct something *)data;
          ...
          }
          ...
          setup_timer(&ptr->my_timer, my_callback, ptr);
      
      and forced object casts:
      
          void my_callback(struct something *ptr)
          {
          ...
          }
          ...
          setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);
      
      become:
      
          void my_callback(struct timer_list *t)
          {
              struct something *ptr = from_timer(ptr, t, my_timer);
          ...
          }
          ...
          timer_setup(&ptr->my_timer, my_callback, 0);
      
      Direct function assignments:
      
          void my_callback(unsigned long data)
          {
              struct something *ptr = (struct something *)data;
          ...
          }
          ...
          ptr->my_timer.function = my_callback;
      
      have a temporary cast added, along with converting the args:
      
          void my_callback(struct timer_list *t)
          {
              struct something *ptr = from_timer(ptr, t, my_timer);
          ...
          }
          ...
          ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;
      
      And finally, callbacks without a data assignment:
      
          void my_callback(unsigned long data)
          {
          ...
          }
          ...
          setup_timer(&ptr->my_timer, my_callback, 0);
      
      have their argument renamed to verify they're unused during conversion:
      
          void my_callback(struct timer_list *unused)
          {
          ...
          }
          ...
          timer_setup(&ptr->my_timer, my_callback, 0);
      
      The conversion is done with the following Coccinelle script:
      
      spatch --very-quiet --all-includes --include-headers \
      	-I ./arch/x86/include -I ./arch/x86/include/generated \

      bnx2x: fix slowpath null crash · 442866ff
      Zhu Yanjun 提交于
      When "NETDEV WATCHDOG: em4 (bnx2x): transmit queue 2 timed out" occurs,
      BNX2X_SP_RTNL_TX_TIMEOUT is set. In the function bnx2x_sp_rtnl_task,
      bnx2x_nic_unload and bnx2x_nic_load are executed to shutdown and open
      NIC. In the function bnx2x_nic_load, bnx2x_alloc_mem allocates dma
      failure. The message "bnx2x: [bnx2x_alloc_mem:8399(em4)]Can't
      allocate memory" pops out. The variable slowpath is set to NULL.
      When shutdown the NIC, the function bnx2x_nic_unload is called. In
      the function bnx2x_nic_unload, the following functions are executed.
      bnx2x_chip_cleanup
          bnx2x_set_storm_rx_mode
              bnx2x_set_q_rx_mode
                  bnx2x_set_q_rx_mode
                      bnx2x_config_rx_mode
                          bnx2x_set_rx_mode_e2
      In the function bnx2x_set_rx_mode_e2, the variable slowpath is operated.
      Then the crash occurs.
      To fix this crash, the variable slowpath is checked. And in the function
      bnx2x_sp_rtnl_task, after dma memory allocation fails, another shutdown
      and open NIC is executed.

      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.
