      rtnetlink: Compute and store minimum ifinfo dump size · c7ac8679
      Greg Rose authored
      The message size allocated for rtnl ifinfo dumps was limited to
      a single page.  This is not enough for additional interface info
      available with devices that support SR-IOV and caused a bug in
      which VF info would not be displayed if more than approximately
      40 VFs were created per interface.
      
      Implement a new function pointer for the rtnl_register service that will
      calculate the amount of data required for the ifinfo dump and allocate
      enough data to satisfy the request.

      ipv6: add a missing unregister_pernet_subsys call · 2cc6d2bf
      Neil Horman authored
      Clean up a missing exit path in the ipv6 module init routines.  In
      addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys
      for the ipv6_addr_label_ops structure.  But if module loading fails, or if the
      ipv6 module is removed, there is no corresponding unregister_pernet_subsys call,
      which leaves a now-bogus address on the pernet_list, leading to oopses in
      subsequent registrations.  This patch cleans up both the failed load path and
      the unload path.  Tested by myself with good results.

      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.

      ipv6 netns: Address labels per namespace · 3de23255
      Benjamin Thery authored
      This pacth makes IPv6 address labels per network namespace.
      It keeps the global label tables, ip6addrlbl_table, but
      adds a 'net' member to each ip6addrlbl_entry.
      This new member is taken into account when matching labels.
      
      Changelog
      =========
      * v1: Initial version
      * v2:
        * Minize the penalty when network namespaces are not configured:
            *  the 'net' member is added only if CONFIG_NET_NS is
               defined. This saves space when network namespaces are not
               configured.
            * 'net' value is retrieved with the inlined function
               ip6addrlbl_net() that always return &init_net when
               CONFIG_NET_NS is not defined.
        * 'net' member in ip6addrlbl_entry renamed to the less generic
          'lbl_net' name (helps code search).
