      net: Add compat ioctl support for the ipv4 multicast ioctl SIOCGETSGCNT · 709b46e8
      Eric W. Biederman 提交于
      SIOCGETSGCNT is not a unique ioctl value as it it maps tio SIOCPROTOPRIVATE +1,
      which unfortunately means the existing infrastructure for compat networking
      ioctls is insufficient.  A trivial compact ioctl implementation would conflict
      with:
      
      SIOCAX25ADDUID
      SIOCAIPXPRISLT
      SIOCGETSGCNT_IN6
      SIOCGETSGCNT
      SIOCRSSCAUSE
      SIOCX25SSUBSCRIP
      SIOCX25SDTEFACILITIES
      
      To make this work I have updated the compat_ioctl decode path to mirror the
      the normal ioctl decode path.  I have added an ipv4 inet_compat_ioctl function
      so that I can have ipv4 specific compat ioctls.   I have added a compat_ioctl
      function into struct proto so I can break out ioctls by which kind of ip socket
      I am using.  I have added a compat_raw_ioctl function because SIOCGETSGCNT only
      works on raw sockets.  I have added a ipmr_compat_ioctl that mirrors the normal
      ipmr_ioctl.
      
      This was necessary because unfortunately the struct layout for the SIOCGETSGCNT
      has unsigned longs in it so changes between 32bit and 64bit kernels.
      
      This change was sufficient to run a 32bit ip multicast routing daemon on a
      64bit kernel.

      IPv4: unresolved multicast route cleanup · bbd72543
      Andreas Meissner 提交于
      Fixes the expiration timer for unresolved multicast route entries.
      In case new multicast routing requests come in faster than the 
      expiration timeout occurs (e.g. zap through multicast TV streams), the 
      timer is prevented from being called at time for already existing entries.
      
      As the single timer is resetted to default whenever a new entry is made, 
      the timeout for existing unresolved entires are missed and/or not 
      updated. As a consequence new requests are denied when the limit of 
      unresolved entries has been reached because old entries live longer than 
      they are supposed to.
      
      The solution is to reset the timer only for the first unresolved entry 
      in the multicast routing cache. All other timers are already set and 
      updated correctly within the timer function itself by now.

      net: ipmr: add support for dumping routing tables over netlink · cb6a4e46
      Patrick McHardy 提交于
      The ipmr /proc interface (ip_mr_cache) can't be extended to dump routes
      from any tables but the main table in a backwards compatible fashion since
      the output format ends in a variable amount of output interfaces.
      
      Introduce a new netlink interface to dump multicast routes from all tables,
      similar to the netlink interface for regular routes.

      net: rtnetlink: decouple rtnetlink address families from real address families · 25239cee
      Patrick McHardy 提交于
      Decouple rtnetlink address families from real address families in socket.h to
      be able to add rtnetlink interfaces to code that is not a real address family
      without increasing AF_MAX/NPROTO.
      
      This will be used to add support for multicast route dumping from all tables
      as the proc interface can't be extended to support anything but the main table
      without breaking compatibility.
      
      This partialy undoes the patch to introduce independant families for routing
      rules and converts ipmr routing rules to a new rtnetlink family. Similar to
      that patch, values up to 127 are reserved for real address families, values
      above that may be used arbitrarily.

      net: fib_rules: mark arguments to fib_rules_register const and __net_initdata · 3d0c9c4e

      fib_rules_register() duplicates the template passed to it without modification,
      mark the argument as const. Additionally the templates are only needed when
      instantiating a new namespace, so mark them as __net_initdata, which means
      they can be discarded when CONFIG_NET_NS=n.

      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.
