      procfs: new helper - PDE_DATA(inode) · d9dda78b
      Al Viro 提交于
      The only part of proc_dir_entry the code outside of fs/proc
      really cares about is PDE(inode)->data.  Provide a helper
      for that; static inline for now, eventually will be moved
      to fs/proc, along with the knowledge of struct proc_dir_entry
      layout.

      net: fix 64 bit counters on 32 bit arches · 28172739
      Eric Dumazet 提交于
      There is a small possibility that a reader gets incorrect values on 32
      bit arches. SNMP applications could catch incorrect counters when a
      32bit high part is changed by another stats consumer/provider.
      
      One way to solve this is to add a rtnl_link_stats64 param to all
      ndo_get_stats64() methods, and also add such a parameter to
      dev_get_stats().
      
      Rule is that we are not allowed to use dev->stats64 as a temporary
      storage for 64bit stats, but a caller provided area (usually on stack)
      
      Old drivers (only providing get_stats() method) need no changes.

      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.

      USB: gadget: Add EEM gadget driver · 9b39e9dd
      Brian Niebuhr 提交于
      This patch adds a CDC EEM ethernet gadget driver.  CDC EEM is a newer
      USB ethernet specification that uses a simpler interface than the older
      CDC ECM.  This makes CDC EEM usable by a wider set of USB hardware.
      By default the ethernet gadget will still use CDC ECM/Subset, but kernel
      configuration and/or a module parameter will allow alternative use of
      the CDC EEM protocol.
      
      Changes since last version:
      	- Brought in missing RNDIS changes that caused compile error
      	- Modified 'sentinel CRC' checking to match EEM host driver

      usb gadget: RNDIS cleanups · 15b2d2b5
      David Brownell 提交于
      Some cleanup to the RNDIS code:
      
       - Minor bugfix:  rndis_unit() is supposed to put the link into the
         RNDIS_UNINITIALIZED state, which does not mean "unused".  There's
         a separate method to stop using the link.  (Bug doesn't affect
         anything right now because of how the code is used.)
      
       - Reduce coupling between RNDIS code and its user(s), in preparation
         for updates in that code:
      
          * Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device
            by passing just a void* handle.  (Also, remove the unused return
            value of the notification callback.)
          * When it needs a copy of net_device stats, just ask for it
      
       - Remove unused/untested code backing various never-used OIDs:
      
          * RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the
            relevant docs were unclear, ambguous, and incomplete.  Someone
            with access to the Hidden Gospels (maybe in the EU?) might be
            able to figure out what this should do.
          * RNDIS_OPTIONAL_STATS ... as the name suggests, optional.  Never
            implemented in part because not all the semantics were clear.
          * OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever.
      
       - A few small whitespace fixes
      
      Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style.
      
      There should be no functional changes because of this patch; it's a
      net source code shrink (because of the dead/unused code removal) and
      a small object code shrink (a couple hundred bytes on ARMv5).

      USB: usb gadgets avoid le{16,32}_to_cpup() · 01ee7d70
      David Brownell 提交于
      It turns out that le16_to_cpup() and le32_to_cpup() aren't always safe
      to call with pointers into packed structures, since those are inlined
      functions and GCC may lose the "packed" attribute.  So those references
      can become unaligned kernel accesses, which are evil on some hardware.
      
      This patch updates uses of those routines in the gadget stack.  The
      references into packed structures can just use leXX_to_cpu(*x), which
      in most cases is more natural.  Some other uses in RNDIS, mostly in
      debug code, were wrong in the first place; those use get_unaligned().

      [PATCH] USB: gadget section fixups · a353678d
      David Brownell 提交于
      Recent section changes broke gadget builds on some platforms.  This patch
      is the best fix that's available until better section markings exist:
      
       - There's a lot of cleanup code that gets used in both init and exit paths;
         stop marking it as "__exit".
      
         (Best fix for this would be an "__init_or_exit" section marking, putting
         the cleanup in __init when __exit sections get discarded else in __exit.)
      
       - Stop marking the use-once probe routines as "__init" since references
         to those routines are not allowed from driver structures.  They're now
         marked "__devinit", which in practice is a net lose.
      
         (Best fix for this is likely to separate such use-once probe routines
         from the driver structure ... but in general, all busses that aren't
         hotpluggable will be forced to waste memory for all probe-only code.)
      
      In general these broken section rules waste an average of two to four kBytes
      per driver of code bloat ... because none of the relevant code can ever be
      reused after module initialization.
