      net: Fix ipv6 neighbour unregister_sysctl_table warning · bf36076a
      Eric W. Biederman 提交于
      In my testing of 2.6.37 I was occassionally getting a warning about
      sysctl table entries being unregistered in the wrong order.  Digging
      in it turns out this dates back to the last great sysctl reorg done
      where Al Viro introduced the requirement that sysctl directories
      needed to be created before and destroyed after the files in them.
      
      It turns out that in that great reorg /proc/sys/net/ipv6/neigh was
      overlooked.  So this patch fixes that oversight and makes an annoying
      warning message go away.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      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.

      sysctl net: Remove unused binary sysctl code · f8572d8f
      Eric W. Biederman 提交于
      Now that sys_sysctl is a compatiblity wrapper around /proc/sys
      all sysctl strategy routines, and all ctl_name and strategy
      entries in the sysctl tables are unused, and can be
      revmoed.
      
      In addition neigh_sysctl_register has been modified to no longer
      take a strategy argument and it's callers have been modified not
      to pass one.

      Alexey Dobriyan 提交于
      I want to compile out proc_* and sysctl_* handlers totally and
      stub them to NULL depending on config options, however usage of &
      will prevent this, since taking adress of NULL pointer will break
      compilation.
      
      So, drop & in front of every ->proc_handler and every ->strategy
      handler, it was never needed in fact.

      missing bits of net-namespace / sysctl · eeb61f71

      Piss-poor sysctl registration API strikes again, film at 11...
      
      What we really need is _pathname_ required to be present in already
      registered table, so that kernel could warn about bad order.  That's the
      next target for sysctl stuff (and generally saner and more explicit
      order of initialization of ipv[46] internals wouldn't hurt either).
      
      For the time being, here are full fixups required by ..._rotable()
      stuff; we make per-net sysctl sets descendents of "ro" one and make sure
      that sufficient skeleton is there before we start registering per-net

      [PATCH] sysctl: remove insert_at_head from register_sysctl · 0b4d4147
      Eric W. Biederman 提交于
      The semantic effect of insert_at_head is that it would allow new registered
      sysctl entries to override existing sysctl entries of the same name.  Which is
      pain for caching and the proc interface never implemented.
      
      I have done an audit and discovered that none of the current users of
      register_sysctl care as (excpet for directories) they do not register
      duplicate sysctl entries.
      
      So this patch simply removes the support for overriding existing entries in
      the sys_sysctl interface since no one uses it or cares and it makes future
      enhancments harder.

      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
