      ethtool: Remove unimplemented flow specification types · e0de7c93
      Ben Hutchings authored
      
      
      struct ethtool_rawip4_spec and struct ethtool_ether_spec are neither
      commented nor used by any driver, so remove them.  Adjust padding in
      the user-visible unions that included these structures.
      
      Fix references to struct ethtool_rawip4_spec in
      ethtool_get_rx_ntuple(), which should use struct ethtool_usrip4_spec.
      
      struct ethtool_usrip4_spec cannot hold IPv6 host addresses and there
      is no separate structure that can, so remove ETH_RX_NFC_IP6 and the
      reference to it in niu.

      ethtool: allow non-netadmin to query settings · 0fdc100b
      stephen hemminger authored
      
      
      The SNMP daemon uses ethtool to determine the speed of
      network interfaces. This fails on Debian (and probably elsewhere)
      because for security SNMP daemon runs as non-root user (snmp).
      
      Note: A similar patch was rejected previously because of a concern about
      the possibility that on some hardware querying the ethtool settings
      requires access to the PHY and could slow the machine down.  But the
      security risk of requiring SNMP daemon (and related services)
      to run as root far out weighs the risk of denial-of-service.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      Debatable -- the current comment is located at the callsite of
      ops->get_sset_count(), which is where an implementor might think to add
      a new call.  Not all the numeric fields in ethtool_drvinfo are obtained
      from ->get_sset_count().
      
      Hence the "some" in the attached patch to include/linux/ethtool.h,
      addressing your comment.

      Agreed.
      
      I've attached a follow-up patch, which should enable my/Jeff's kernel
      patch to be applied, followed by this one.

      This patch is an alternative approach for accessing string
      counts, vs. the drvinfo indirect approach.  This way the drvinfo
      space doesn't run out, and we don't break ABI later.

      ethtool: Add reset operation · d73d3a8c
      Ben Hutchings authored
      
      
      After updating firmware stored in flash, users may wish to reset the
      relevant hardware and start the new firmware immediately.  This should
      not be completely automatic as it may be disruptive.
      
      A selective reset may also be useful for debugging or diagnostics.
      
      This adds a separate reset operation which takes flags indicating the
      components to be reset.  Drivers are allowed to reset only a subset of
      those requested, and must indicate the actual subset.  This allows the
      use of generic component masks and some future expansion.
