      compat: cleanup coding in compat_get_bitmap() and compat_put_bitmap() · 9b7b819c
      Helge Deller authored
      
      
      In the functions compat_get_bitmap() and compat_put_bitmap() the
      variable nr_compat_longs stores how many compat_ulong_t words should be
      copied in a loop.
      
      The copy loop itself is this:
        if (nr_compat_longs-- > 0) {
            if (__get_user(um, umask)) return -EFAULT;
        } else {
            um = 0;
        }
      
      Since nr_compat_longs gets unconditionally decremented in each loop and
      since it's type is unsigned this could theoretically lead to out of
      bounds accesses to userspace if nr_compat_longs wraps around to
      (unsigned)(-1).
      
      Although the callers currently do not trigger out-of-bounds accesses, we
      should better implement the loop in a safe way to completely avoid such
      warp-arounds.

      However if a packet is localy sent, the PMTU mechanism
      of xfrm tries to to local socket notification what
      might not work for applications like ping that don't

      It isn't right, ethtool is meant to manage one PHY instance
      per netdevice at a time, and this is selected by the SET

      bnx2x: Move statistics implementation into semaphores · c6e36d8c
      Yuval Mintz authored
      Commit dff173de
      
       ("bnx2x: Fix statistics locking scheme") changed the
      bnx2x locking around statistics state into using a mutex - but the lock
      is being accessed via a timer which is forbidden.
      
      [If compiled with CONFIG_DEBUG_MUTEXES, logs show a warning about
      accessing the mutex in interrupt context]
      
      This moves the implementation into using a semaphore [with size '1']
      instead.

      xen: netback: read hotplug script once at start of day. · 31a41898
      Ian Campbell authored
      
      
      When we come to tear things down in netback_remove() and generate the
      uevent it is possible that the xenstore directory has already been
      removed (details below).
      
      In such cases netback_uevent() won't be able to read the hotplug
      script and will write a xenstore error node.
      
      A recent change to the hypervisor exposed this race such that we now
      sometimes lose it (where apparently we didn't ever before).
      
      Instead read the hotplug script configuration during setup and use it
      for the lifetime of the backend device.
      
      The apparently more obvious fix of moving the transition to
      state=Closed in netback_remove() to after the uevent does not work
      because it is possible that we are already in state=Closed (in
      reaction to the guest having disconnected as it shutdown). Being
      already in Closed means the toolstack is at liberty to start tearing
      down the xenstore directories. In principal it might be possible to
      arrange to unregister the device sooner (e.g on transition to Closing)
      such that xenstore would still be there but this state machine is
      fragile and prone to anger...
      
      A modern Xen system only relies on the hotplug uevent for driver
      domains, when the backend is in the same domain as the toolstack it
      will run the necessary setup/teardown directly in the correct sequence
      wrt xenstore changes.

      sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE
      
      Bit 9 of TTE is CV (Cacheable in V-cache) on sparc v9 processor while
      the same bit 9 is MCDE (Memory Corruption Detection Enable) on M7
      processor. This creates a conflicting usage of the same bit. Kernel
      sets TTE.cv bit on all pages for sun4v architecture which works well
      for sparc v9 but enables memory corruption detection on M7 processor
      which is not the intent. This patch adds code to determine if kernel
      is running on M7 processor and takes steps to not enable memory
      corruption detection in TTE erroneously.

      net: dsa: Properly propagate errors from dsa_switch_setup_one · 24595346
      Florian Fainelli authored
      While shuffling some code around, dsa_switch_setup_one() was introduced,
      and it was modified to return either an error code using ERR_PTR() or a
      NULL pointer when running out of memory or failing to setup a switch.
      
      This is a problem for its caler: dsa_switch_setup() which uses IS_ERR()
      and expects to find an error code, not a NULL pointer, so we still try
      to proceed with dsa_switch_setup() and operate on invalid memory
      addresses. This can be easily reproduced by having e.g: the bcm_sf2
      driver built-in, but having no such switch, such that drv->setup will
      fail.
      
      Fix this by using PTR_ERR() consistently which is both more informative
      and avoids for the caller to use IS_ERR_OR_NULL().

      tcp: fix child sockets to use system default congestion control if not set · 9f950415
      Neal Cardwell authored
      Linux 3.17 and earlier are explicitly engineered so that if the app
      doesn't specifically request a CC module on a listener before the SYN
      arrives, then the child gets the system default CC when the connection
      is established. See tcp_init_congestion_control() in 3.17 or earlier,
      which says "if no choice made yet assign the current value set as
      default". The change ("net: tcp: assign tcp cong_ops when tcp sk is
      created") altered these semantics, so that children got their parent
      listener's congestion control even if the system default had changed
      after the listener was created.
      
      This commit returns to those original semantics from 3.17 and earlier,
      since they are the original semantics from 2007 in 4d4d3d1e ("[TCP]:
      Congestion control initialization."), and some Linux congestion
      control workflows depend on that.
      
      In summary, if a listener socket specifically sets TCP_CONGESTION to
      "x", or the route locks the CC module to "x", then the child gets
      "x". Otherwise the child gets current system default from
      net.ipv4.tcp_congestion_control. That's the behavior in 3.17 and
      earlier, and this commit restores that.

      udp: fix behavior of wrong checksums · beb39db5
      Eric Dumazet authored
      
      
      We have two problems in UDP stack related to bogus checksums :
      
      1) We return -EAGAIN to application even if receive queue is not empty.
         This breaks applications using edge trigger epoll()
      
      2) Under UDP flood, we can loop forever without yielding to other
         processes, potentially hanging the host, especially on non SMP.
      
      This patch is an attempt to make things better.
      
      We might in the future add extra support for rt applications
      wanting to better control time spent doing a recv() in a hostile
      environment. For example we could validate checksums before queuing
      packets in socket receive queue.

      Daniel Pieczko authored
      
      
      When Rx packet data must be dropped, all the buffers
      associated with that Rx packet must be freed. Extend
      and rename efx_free_rx_buffer() to efx_free_rx_buffers()
      and loop through all the fragments.
      By doing so this patch fixes a possible memory leak.

       "Off-by-one in d_walk()/__dentry_kill() race fix.
      
        It's very hard to hit; possible in the same conditions as the original
        bug, except that you need the skipped branch to contain all the
        remaining evictables, so that the d_walk()-calling loop in
        d_invalidate() decides there's nothing more to do and doesn't go for
        another pass - otherwise that next pass will sweep the sucker.
      
        So it's not too urgent, but seeing that the fix is obvious and the
        original commit has spread into all -stable branches..."

      bna: fix soft lock-up during firmware initialization failure · 4818e856
      Ivan Vecera authored
      
      
      Bug in the driver initialization causes soft-lockup if firmware
      initialization timeout is reached. Polling function bfa_ioc_poll_fwinit()
      incorrectly calls bfa_nw_iocpf_timeout() when the timeout is reached.
      The problem is that bfa_nw_iocpf_timeout() calls again
      bfa_ioc_poll_fwinit()... etc. The bfa_ioc_poll_fwinit() should directly
      send timeout event for iocpf and the same should be done if firmware
      download into HW fails.

      bna: remove unreasonable iocpf timer start · 4918eb1e
      Ivan Vecera authored
      
      
      Driver starts iocpf timer prior bnad_ioceth_enable() call and this is
      unreasonable. This piece of code probably originates from Brocade/Qlogic
      out-of-box driver during initial import into upstream. This driver uses
      only one timer and queue to implement multiple timers and this timer is
      started at this place. The upstream driver uses multiple timers instead
      of this.
