      mac80211: handle HW ROC expired properly · 1b894521
      由 Ilan Peer 提交于 
      In case of HW ROC, when the driver reports that the ROC expired,
it is not sufficient to purge the ROCs based on the remaining
time, as it possible that the device finished the ROC session
before the actual requested duration.

To handle such cases, in case of ROC expired notification from
the driver, complete all the ROCs which are marked with hw_begun,
regardless of the remaining duration.

      af_unix: fix unix_dgram_recvmsg entry locking · 64874280
      由 Rainer Weikusat 提交于 
      The current unix_dgram_recvsmg code acquires the u->readlock mutex in
order to protect access to the peek offset prior to calling
__skb_recv_datagram for actually receiving data. This implies that a
blocking reader will go to sleep with this mutex held if there's
presently no data to return to userspace. Two non-desirable side effects
of this are that a later non-blocking read call on the same socket will
block on the ->readlock mutex until the earlier blocking call releases it
(or the readers is interrupted) and that later blocking read calls
will wait longer than the effective socket read timeout says they
should: The timeout will only start 'ticking' once such a reader hits
the schedule_timeout in wait_for_more_packets (core.c) while the time it
already had to wait until it could acquire the mutex is unaccounted for.

The patch avoids both by using the __skb_try_recv_datagram and
__skb_wait_for_more packets functions created by the first patch to
implement a unix_dgram_recvmsg read loop which releases the readlock
mutex prior to going to sleep and reacquires it as needed
afterwards. Non-blocking readers will thus immediately return with
-EAGAIN if there's no data available regardless of any concurrent
blocking readers and all blocking readers will end up sleeping via
schedule_timeout, thus honouring the configured socket receive timeout.

      core: enable more fine-grained datagram reception control · ea3793ee
      由 Rainer Weikusat 提交于 
      The __skb_recv_datagram routine in core/ datagram.c provides a general
skb reception factility supposed to be utilized by protocol modules
providing datagram sockets. It encompasses both the actual recvmsg code
and a surrounding 'sleep until data is available' loop. This is
inconvenient if a protocol module has to use additional locking in order
to maintain some per-socket state the generic datagram socket code is
unaware of (as the af_unix code does). The patch below moves the recvmsg
proper code into a new __skb_try_recv_datagram routine which doesn't
sleep and renames wait_for_more_packets to
__skb_wait_for_more_packets, both routines being exported interfaces. The
original __skb_recv_datagram routine is reimplemented on top of these
two functions such that its user-visible behaviour remains unchanged.

      PHY: DP83867: Remove looking in parent device for OF properties · 7bf9ae01
      由 Andrew Lunn 提交于 
      Device tree properties for a phy device are expected to be in the phy
node. The current code for the DP83867 also tries to look in the
parent node. The devices binding documentation does not mention this,
no current device tree file makes use of this, and it is not behaviour
we want. So remove looking in the parent device.

      net: cdc_ncm: add "ndp_to_end" sysfs attribute · 404814af
      由 Bjørn Mork 提交于 
      Adding a writable sysfs attribute for the "NDP to end"
quirk flag.

This makes it easier for end users to test new devices for
this firmware bug.  We've been lucky so far, but we should
not depend on reporters capable of rebuilding the driver.

      Merge branch 'mlx4-HA-LAG-SRIOV-VF' · 0fe3e204
      由 David S. Miller 提交于 
      Or Gerlitz says:

====================
Add HA and LAG support for mlx4 SRIOV VFs

This series is built upon the code added in commit ce388fff "Merge branch
'mlx4-next'" which added HA and LAG support to mlx4 RoCE and SRIOV services.

We add HA and Link Aggregation support to single ported mlx4 Ethernet VFs.

In this case, the PF Ethernet interfaces are bonded, the VFs see single
port HW devices (already supported) -- however, now this port is highly
available. This means that all VF HW QPs (both VF Ethernet driver and VF
RoCE / RAW QPs) are subject to the V2P (Virtual-To-Physical) mapping which
is managed by the PF driver, and hence resilient across link failures and
such events.

When bonding operates in Dynamic link aggregation (802.3ad) mode, traffic
from each VF will go over the VF "base port" (the port this VF is assigned
to by the admin) as long as this port is up. When the port fails, traffic
from all VFs that are defined on this port will move to the other port, and
be back to their base-port when it recovers.

Moni and Or.

      net/mlx4_core: Support the HA mode for SRIOV VFs too · e57968a1
      由 Moni Shoua 提交于 
      When the mlx4 driver runs in HA mode, and all VFs are single ported
ones, we make their single port Highly-Available.

This is done by taking advantage of the HA mode properties (following
bonding changes with programming the port V2P map, etc) and adding
the missing parts which are unique to SRIOV such as mirroring VF
steering rules on both ports.

Due to limits on the MAC and VLAN table this mode is enabled only when
number of total VFs is under 64.
