      sendmmsg/sendmsg: fix unsafe user pointer access · bc909d9d
      Mathieu Desnoyers 提交于
      Dereferencing a user pointer directly from kernel-space without going
      through the copy_from_user family of functions is a bad idea. Two of
      such usages can be found in the sendmsg code path called from sendmmsg,
      added by
      
      commit c71d8ebe upstream.
      commit 5b47b8038f183b44d2d8ff1c7d11a5c1be706b34 in the 3.0-stable tree.
      
      Usages are performed through memcmp() and memcpy() directly. Fix those
      by using the already copied msg_sys structure instead of the __user *msg
      structure. Note that msg_sys can be set to NULL by verify_compat_iovec()
      or verify_iovec(), which requires additional NULL pointer checks.

      arp: fix rcu lockdep splat in arp_process() · 20e6074e
      Eric Dumazet 提交于
      Dave Jones reported a lockdep splat triggered by an arp_process() call
      from parp_redo().
      
      Commit faa9dcf7 (arp: RCU changes) is the origin of the bug, since
      it assumed arp_process() was called under rcu_read_lock(), which is not
      true in this particular path.
      
      Instead of adding rcu_read_lock() in parp_redo(), I chose to add it in
      neigh_proxy_process() to take care of IPv6 side too.

      carl9170: Fix mismatch in carl9170_op_set_key mutex lock-unlock · 66cb54bd
      Alexey Khoroshilov 提交于
      If is_main_vif(ar, vif) reports that we have to fall back
      to software encryption, we goto err_softw; before locking ar->mutex.
      As a result, we have unprotected call to carl9170_set_operating_mode
      and unmatched mutex_unlock.
      
      The patch fix the issue by adding mutex_lock before goto.
