b79858dac6 Send frames to mesh gate if 11s discovery fails.
* Send frames that have no path to a known valid Mesh Gate;
* Added the function ieee80211_mesh_forward_to_gates that sends the frame
  to the first found Mesh Gate in the forwarding information;
* If we try to discover again while we are discovering queue frame,
  the discovery callout will send the frames either to mesh gates
  or discards them silently;
* Queue frame also if we try to discover to frequently;

* Modified mesh_recv_action_meshgate to do following:
    + if mesh STA already knows the mesh gate of the recevied GANN frame
    + if mesh gate is know, check seq number according to 802.11 standard
    + if mesh gate is not know, add it to the list of known mesh gates
    + if forwarding is enabled and ttl >= 1 then propagate the GANN frame;
* Declare a new malloc type M_80211_MESH_GT_RT;
* Declare a struct to store GANN information, ieee80211_mesh_gate_route. And
  add it as a TAILQ list to ieee80211_mesh_state;

ed0b544066 Mesh update: add base Mesh Gate functionality.
A Mesh Gate should transmit a Mesh Action frame containing
ieee80211_meshgann_ie as its only information element periodically
every ieee80211_mesh_gateint ms. Unless the mesh gate is also configure
as a ROOT, then these frames should not be send.
This is according to 802.11 2012 standard;

* Introduce new SYSCTL net.wlan.mesh.gateint, with 10s default;
* Add two new functions mesh_gatemode_setup and mesh_gatemode_cb. This
  is similar to how HWMP setups up a callout;
* Add two new action handlers mesh_recv_action_meshgate and
  mesh_send_action_meshgate;
* Added ieee80211_add_meshgate to ieee80211_mesh.h;
* Modified mesh_send_action to look similar to hwmp_send_action. This is
  because we need to send out broadcast management frames.
* Introduced a new flag for mesh state IEEE80211_MESHFLAGS_ROOT. This flag
  is now set by HWMP code when a mesh STA is configured as a ROOT. This
  is then checked by mesh_gatemode_cb before scheduling a new callout;
* Added to new field to ieee80211_mesh_state:
    + struct callout                  ms_gatetimer
    + ieee80211_mesh_seq              ms_gateseq;

  IEEE80211_ACTION_CAT_MESH frames, if not frame is discarded. This is

ff17492f7c Stop a mesh STA from flooding with peer frames.
This problem happens when using ACL policy to filter mesh STA
but two nodes have different policy. Then one of them will try to
peer all the time. This can also help if for any reason one of the
peering mesh STA have problems sending/receiving peer frames.

* Modified struct ieee80211_node to include two new fields:
    + struct callout ni_mlhtimer /* link mesh backoff timer */
    + uint8_t ni_mlhcnt /* link mesh holding counter */
* Added two new sysctl (check sysctl -d for more info):
    + net.wlan.mesh.backofftimeout=5000
    + net.wlan.mesh.maxholding=2;
* When receiving a beacon and we are in IEEE80211_NODE_MESH_IDLE
  check if ni_mlhcnt >= ieee80211_mesh_maxholding, if so do not do anything;
* In mesh_peer_timeout_cb when transitioning from IEEE80211_NODE_MESH_HOLDING
  to IEEE80211_NODE_MESH_IDLE increment ni_mlhcnt, and eventually start
  ieee80211_mesh_backofftimeout;

888d4d4f86 When vforked child is traced, the debugging events are not generated
until child performs exec().  The behaviour is reasonable when a
debugger is the real parent, because the parent is stopped until
exec(), and sending a debugging event to the debugger would deadlock
both parent and child.

On the other hand, when debugger is not the parent of the vforked
child, not sending debugging signals makes it impossible to debug
across vfork.

Fix the issue by declining generating debug signals only when vfork()
was done and child called ptrace(PT_TRACEME).  Set a new process flag
P_PPTRACE from the attach code for PT_TRACEME, if P_PPWAIT flag is
set, which indicates that the process was created with vfork() and
still did not execed. Check P_PPTRACE from issignal(), instead of
refusing the trace outright for the P_PPWAIT case.  The scope of
P_PPTRACE is exactly contained in the scope of P_PPWAIT.

ded5ea6a25 This fixes a out-of-order problem with several
of the newer drivers. The basic problem was
that the driver was pulling the mbuf off the
drbr ring and then when sending with xmit(), encounting
a full transmit ring. Thus the lower layer
xmit() function would return an error, and the
drivers would then append the data back on to the ring.
For TCP this is a horrible scenario sure to bring
on a fast-retransmit.

The fix is to use drbr_peek() to pull the data pointer
but not remove it from the ring. If it fails then
we either call the new drbr_putback or drbr_advance
method. Advance moves it forward (we do this sometimes
when the xmit() function frees the mbuf). When
we succeed we always call advance. The
putback will always copy the mbuf back to the top
of the ring. Note that the putback *cannot* be used
with a drbr_dequeue() only with drbr_peek(). We most
of the time, in putback, would not need to copy it
back since most likey the mbuf is still the same, but
sometimes xmit() functions will change the mbuf via
a pullup or other call. So the optimial case for
the single consumer is to always copy it back. If
we ever do a multiple_consumer (for lagg?) we
will  need a test and atomic in the put back possibly
a seperate putback_mc() in the ring buf.

Posix requires that open(2) is restartable for SA_RESTART.

For non-posix objects, in particular, devfs nodes, still disable
automatic restart of the opens. The open call to a driver could have
significant side effects for the hardware.

a120a7a3cd Rework the handling of stop signals in the NFS client. The changes in
195702, 195703, and 195821 prevented a thread from suspending while holding
locks inside of NFS by forcing the thread to fail sleeps with EINTR or
ERESTART but defer the thread suspension to the user boundary.  However,
this had the effect that stopping a process during an NFS request could
abort the request and trigger EINTR errors that were visible to userland
processes (previously the thread would have suspended and completed the
request once it was resumed).

This change instead effectively masks stop signals while in the NFS client.
It uses the existing TDF_SBDRY flag to effect this since SIGSTOP cannot
be masked directly.  Also, instead of setting PBDRY on individual sleeps,
the NFS client now sets the TDF_SBDRY flag around each NFS request and
stop signals are masked for all sleeps during that region (the previous
change missed sleeps in lockmgr locks).  The end result is that stop
signals sent to threads performing an NFS request are completely
ignored until after the NFS request has finished processing and the
thread prepares to return to userland.  This restores the behavior of
stop signals being transparent to userland processes while still
preventing threads from suspending while holding NFS locks.
