      mac80211: Fix a rwlock bad magic bug · b57e6b56
      Mohammed Shafi Shajakhan authored
      read_lock(&tpt_trig->trig.leddev_list_lock) is accessed via the path
      ieee80211_open (->) ieee80211_do_open (->) ieee80211_mod_tpt_led_trig
      (->) ieee80211_start_tpt_led_trig (->) tpt_trig_timer before initializing
      it.
      the intilization of this read/write lock happens via the path
      ieee80211_led_init (->) led_trigger_register, but we are doing
      'ieee80211_led_init'  after 'ieeee80211_if_add' where we
      register netdev_ops.
      so we access leddev_list_lock before initializing it and causes the
      following bug in chrome laptops with AR928X cards with the following
      script
      
      while true
      do

      ath9k: Fix kernel panic during driver initilization · 07445f68
      Mohammed Shafi Shajakhan authored
      all works need to be initialized before ieee80211_register_hw
      to prevent mac80211 call backs such as drv_start, drv_config
      getting started. otherwise we would queue/cancel works before
      initializing them and it leads to kernel panic.
      this issue can be recreated with the following script

      mwifiex: handle association failure case correctly · b7097eb7
      Amitkumar Karwar authored
      Currently even if association is failed "iw link" shows some
      information about connected BSS and "Tx timeout" error is seen in
      dmesg log.
      
      This patch fixes below issues in the code to handle assoc failure
      case correctly.
      1) "status" variable in mwifiex_wait_queue_complete() is not
      correctly updated. Hence driver doesn't inform cfg80211 stack
      about association failure.
      2) During association network queues are stopped but carrier is
      not cleared, which gives Tx timeout error in failure case

      af_unix: fix EPOLLET regression for stream sockets · 6f01fd6e
      Eric Dumazet authored
      Commit 0884d7aa (AF_UNIX: Fix poll blocking problem when reading from
      a stream socket) added a regression for epoll() in Edge Triggered mode
      (EPOLLET)
      
      Appropriate fix is to use skb_peek()/skb_unlink() instead of
      skb_dequeue(), and only call skb_unlink() when skb is fully consumed.
      
      This remove the need to requeue a partial skb into sk_receive_queue head
      and the extra sk->sk_data_ready() calls that added the regression.
      
      This is safe because once skb is given to sk_receive_queue, it is not
      modified by a writer, and readers are serialized by u->readlock mutex.
      
      This also reduce number of spinlock acquisition for small reads or
      MSG_PEEK users so should improve overall performance.

      tcp: fix tcp_trim_head() to adjust segment count with skb MSS · 5b35e1e6
      Neal Cardwell authored
      This commit fixes tcp_trim_head() to recalculate the number of
      segments in the skb with the skb's existing MSS, so trimming the head
      causes the skb segment count to be monotonically non-increasing - it
      should stay the same or go down, but not increase.
      
      Previously tcp_trim_head() used the current MSS of the connection. But
      if there was a decrease in MSS between original transmission and ACK
      (e.g. due to PMTUD), this could cause tcp_trim_head() to
      counter-intuitively increase the segment count when trimming bytes off
      the head of an skb. This violated assumptions in tcp_tso_acked() that
      tcp_trim_head() only decreases the packet count, so that packets_acked
      in tcp_tso_acked() could underflow, leading tcp_clean_rtx_queue() to
      pass u32 pkts_acked values as large as 0xffffffff to
      ca_ops->pkts_acked().
      
      As an aside, if tcp_trim_head() had really wanted the skb to reflect
      the current MSS, it should have called tcp_set_skb_tso_segs()
      unconditionally, since a decrease in MSS would mean that a
      single-packet skb should now be sliced into multiple segments.

      net/tcp: Fix tcp memory limits initialization when !CONFIG_SYSCTL · 4acb4190
      Glauber Costa authored
      sysctl_tcp_mem() initialization was moved to sysctl_tcp_ipv4.c
      in commit 3dc43e3e, since it
      became a per-ns value.
      
      That code, however, will never run when CONFIG_SYSCTL is
      disabled, leading to bogus values on those fields - causing hung
      TCP sockets.
      
      This patch fixes it by keeping an initialization code in
      tcp_init(). It will be overwritten by the first net namespace
      init if CONFIG_SYSCTL is compiled in, and do the right thing if
      it is compiled out.
      
      It is also named properly as tcp_init_mem(), to properly signal
      its non-sysctl side effect on TCP limits.

      net: explicitly add jump_label.h header to sock.h · 9018e939
      Glauber Costa authored
      Commit 36a12119 removed linux/module.h
      include statement from one of the headers that end up in net/sock.h.
      It was providing us with static_branch() definition implicitly, so
      after its removal the build got broken.
      
      To fix this, and avoid having this happening in the future,
      let me do the right thing and include linux/jump_label.h

      ipv6: Fix ip_gre lockless xmits. · f2b3ee9e
      Willem de Bruijn authored
      Tunnel devices set NETIF_F_LLTX to bypass HARD_TX_LOCK.  Sit and
      ipip set this unconditionally in ops->setup, but gre enables it
      conditionally after parameter passing in ops->newlink. This is
      not called during tunnel setup as below, however, so GRE tunnels are
      still taking the lock.
      
      modprobe ip_gre
      ip tunnel add test0 mode gre remote 10.5.1.1 dev lo
      ip link set test0 up
      ip addr add 10.6.0.1 dev test0
       # cat /sys/class/net/test0/features
       # $DIR/test_tunnel_xmit 10 10.5.2.1
      ip route add 10.5.2.0/24 dev test0
      ip tunnel del test0
      
      The newlink callback is only called in rtnl_netlink, and only if
      the device is new, as it calls register_netdevice internally. Gre
      tunnels are created at 'ip tunnel add' with ioctl SIOCADDTUNNEL,
      which calls ipgre_tunnel_locate, which calls register_netdev.
      rtnl_newlink is called at 'ip link set', but skips ops->newlink
      and the device is up with locking still enabled. The equivalent
      ipip tunnel works fine, btw (just substitute 'method gre' for
      'method ipip').
      
      On kernels before /sys/class/net/*/features was removed [1],
      the first commented out line returns 0x6000 with method gre,
      which indicates that NETIF_F_LLTX (0x1000) is not set. With ipip,
      it reports 0x7000. This test cannot be used on recent kernels where
      the sysfs file is removed (and ETHTOOL_GFEATURES does not currently
      work for tunnel devices, because they lack dev->ethtool_ops).
      
      The second commented out line calls a simple transmission test [2]
      that sends on 24 cores at maximum rate. Results of a single run:
      
      ipip:			19,372,306
      gre before patch:	 4,839,753
      gre after patch:	19,133,873
      
      This patch replicates the condition check in ipgre_newlink to
      ipgre_tunnel_locate. It works for me, both with oseq on and off.
      This is the first time I looked at rtnetlink and iproute2 code,
      though, so someone more knowledgeable should probably check the
      patch. Thanks.
      
      The tail of both functions is now identical, by the way. To avoid
      code duplication, I'll be happy to rework this and merge the two.

      Port autoselection finds a port and then drop the lock,
      then right after that, gets the hash bucket again and lock it.
      
      Fix it to go direct.

      tcp: bind() fix autoselection to share ports · 2b05ad33
      Flavio Leitner authored
      The current code checks for conflicts when the application
      requests a specific port.  If there is no conflict, then
      the request is granted.
      
      On the other hand, the port autoselection done by the kernel
      fails when all ports are bound even when there is a port
      with no conflict available.
      
      The fix changes port autoselection to check if there is a
      conflict and use it if not.

      l2tp: l2tp_ip - fix possible oops on packet receive · 68315801
      James Chapman authored
      When a packet is received on an L2TP IP socket (L2TPv3 IP link
      encapsulation), the l2tpip socket's backlog_rcv function calls
      xfrm4_policy_check(). This is not necessary, since it was called
      before the skb was added to the backlog. With CONFIG_NET_NS enabled,
      xfrm4_policy_check() will oops if skb->dev is null, so this trivial
      patch removes the call.
      
      This bug has always been present, but only when CONFIG_NET_NS is
      enabled does it cause problems. Most users are probably using UDP
      encapsulation for L2TP, hence the problem has only recently
      surfaced.

      rds: Make rds_sock_lock BH rather than IRQ safe. · efc3dbc3
      David S. Miller authored
      rds_sock_info() triggers locking warnings because we try to perform a
      local_bh_enable() (via sock_i_ino()) while hardware interrupts are
      disabled (via taking rds_sock_lock).
      
      There is no reason for rds_sock_lock to be a hardware IRQ disabling
      lock, none of these access paths run in hardware interrupt context.
      
      Therefore making it a BH disabling lock is safe and sufficient to
      fix this bug.

      A considerable effort was invested in wiping out module.h
      from being present in all the other standard includes.  This
      one leaked back in, but once again isn't strictly necessary,
      so remove it.
