      [NET]: Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolution · ae40eb1e
      Eric Dumazet 提交于
      Now network timestamps use ktime_t infrastructure, we can add a new
      ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'.
      User programs can thus access to nanosecond resolution.

      [NET]: convert network timestamps to ktime_t · b7aa0bf7
      Eric Dumazet 提交于
      We currently use a special structure (struct skb_timeval) and plain
      'struct timeval' to store packet timestamps in sk_buffs and struct
      sock.
      
      This has some drawbacks :
      - Fixed resolution of micro second.
      - Waste of space on 64bit platforms where sizeof(struct timeval)=16
      
      I suggest using ktime_t that is a nice abstraction of high resolution
      time services, currently capable of nanosecond resolution.
      
      As sizeof(ktime_t) is 8 bytes, using ktime_t in 'struct sock' permits
      a 8 byte shrink of this structure on 64bit architectures. Some other
      structures also benefit from this size reduction (struct ipq in
      ipv4/ip_fragment.c, struct frag_queue in ipv6/reassembly.c, ...)
      
      Once this ktime infrastructure adopted, we can more easily provide
      nanosecond resolution on top of it. (ioctl SIOCGSTAMPNS and/or
      SO_TIMESTAMPNS/SCM_TIMESTAMPNS)
      
      Note : this patch includes a bug correction in
      compat_sock_get_timestamp() where a "err = 0;" was missing (so this
      syscall returned -ENOENT instead of 0)

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau 提交于
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).

      [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl · e5ed6399
      Herbert Xu 提交于
      The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
      introduces __in_dev_get_rcu() to cover the second case.
      
      1) RCU with refcnt should use in_dev_get().
      2) RCU without refcnt should use __in_dev_get_rcu().
      3) All others must hold RTNL and use __in_dev_get_rtnl().
      
      There is one exception in net/ipv4/route.c which is in fact a pre-existing
      race condition.  I've marked it as such so that we remember to fix it.
      
      This patch is based on suggestions and prior work by Suzanne Wood and
      Paul McKenney.

      [NET]: move config options out to individual protocols · 6a2e9b73
      Sam Ravnborg 提交于
      Move the protocol specific config options out to the specific protocols.
      With this change net/Kconfig now starts to become readable and serve as a
      good basis for further re-structuring.
      
      The menu structure is left almost intact, except that indention is
      fixed in most cases. Most visible are the INET changes where several
      "depends on INET" are replaced with a single ifdef INET / endif pair.
      
      Several new files were created to accomplish this change - they are
      small but serve the purpose that config options are now distributed
      out where they belongs.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      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
      infrastructure for it.
      
      Let it rip!
