9 years agosctp: on T3_RTX retransmit all the in-flight chunks
Andrei Pelinescu-Onciul [Sun, 29 Nov 2009 08:14:02 +0000]
sctp: on T3_RTX retransmit all the in-flight chunks

When retransmitting due to T3 timeout, retransmit all the
in-flight chunks for the corresponding  transport/path, including
chunks sent less then 1 rto ago.
This is the correct behaviour according to rfc4960 section 6.3.3
E3 and
"Note: Any DATA chunks that were sent to the address for which the
 T3-rtx timer expired but did not fit in one MTU (rule E3 above)
 should be marked for retransmission and sent as soon as cwnd
 allows (normally, when a SACK arrives). ".

This fixes problems when more then one path is present and the T3
retransmission of the first chunk that timeouts stops the T3 timer
for the initial active path, leaving all the other in-flight
chunks waiting forever or until a new chunk is transmitted on the
same path and timeouts (and this will happen only if the cwnd
allows sending new chunks, but since cwnd was dropped to MTU by
the timeout => it will wait until the first heartbeat).

Example: 10 packets in flight, sent at 0.1 s intervals on the
primary path. The primary path is down and the first packet
timeouts. The first packet is retransmitted on another path, the
T3 timer for the primary path is stopped and cwnd is set to MTU.
All the other 9 in-flight packets will not be retransmitted
(unless more new packets are sent on the primary path which depend
on cwnd allowing it, and even in this case the 9 packets will be
retransmitted only after a new packet timeouts which even in the
best case would be more then RTO).

This commit reverts d0ce92910bc04e107b2f3f2048f07e94f570035d and
also removes the now unused transport->last_rto, introduced in
 b6157d8e03e1e780660a328f7183bcbfa4a93a19.

p.s  The problem is not only when multiple paths are there.  It
can happen in a single homed environment.  If the application
stops sending data, it possible to have a hung association.

we have polled, inserted the appropriate events, and then handled the

Instead, make PHY poll functions update the link state synchronously

registers as a shortcut on the SFT9001.

sfc: Simplify XMAC link polling

\177377From: Steve Hodgson <shodgson@solarflare.com>

Only the XMAC on Falcon needs help from the driver to poll and reset
the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later
NICs firmware takes care of the XAUI link.  Also, an XMAC interrupt
currently schedules a work item which simply clears a flag
(efx_nic::mac_up) to be checked by the regular monitor (or the next
link reconfiguration, if that is sooner).

Rename the flag to xmac_poll_required, changing its sense.  Remove the
needless indirection and just set the flag immediately.  Call
falcon_xmac_poll() directly where required.

Add a new generic operation mac_op::check_fault to check the link
outside of regular monitoring, as required during self-tests.

(Note that this leaves us with an unused work item, but we will
immediately have another use for it.)

sfc: Treat all MAC registers as 128-bit

Although all the defined fields in these registers are within 32 bits,
they are architecturally defined as 128-bit like most other Falcon
registers.  In particular, we must use efx_reado() to ensure proper
locking when reading MD_STAT_REG.

9 years agomacvlan: implement bridge, VEPA and private mode
Arnd Bergmann [Thu, 26 Nov 2009 06:07:10 +0000]
macvlan: implement bridge, VEPA and private mode

This allows each macvlan slave device to be in one
of three modes, depending on the use case:

MACVLAN_PRIVATE:
  The device never communicates with any other device
  on the same upper_dev. This even includes frames
  coming back from a reflective relay, where supported
  by the adjacent bridge.

MACVLAN_VEPA:
  The new Virtual Ethernet Port Aggregator (VEPA) mode,
  we assume that the adjacent bridge returns all frames
  where both source and destination are local to the
  macvlan port, i.e. the bridge is set up as a reflective
  relay.
  Broadcast frames coming in from the upper_dev get
  flooded to all macvlan interfaces in VEPA mode.
  We never deliver any frames locally.

MACVLAN_BRIDGE:
  We provide the behavior of a simple bridge between
  different macvlan interfaces on the same port. Frames
  from one interface to another one get delivered directly
  and are not sent out externally. Broadcast frames get
  flooded to all other bridge ports and to the external
  interface, but when they come back from a reflective
  relay, we don't deliver them again.
  Since we know all the MAC addresses, the macvlan bridge
  mode does not require learning or STP like the bridge
  module does.

ssb: Fix SPROM writing

The SPROM writing routines were broken since we rewrote the suspend
handling on wireless devices, because SPROM writing depended on suspend.

This patch changes it and freezes devices with the driver remove(), probe()
callbacks instead. This also simplifies the whole logics a lot.

rndis_wlan: disable stall workaround

Stall workaround doesn't work with bcm4320a devices like with bcm4320b.
This workaround actually causes more stalls/device freeze on bcm4320a.
Therefore disable stall workaround by default.

rndis_wlan: fix buffer overflow in rndis_query_oid

rndis_query_oid overwrites *len which stores buffer size to return full size
of received command and then uses *len with memcpy to fill buffer with
command.

Ofcourse memcpy should be done before replacing buffer size.

iwlwifi: remove reset led_tpt from iwl_leds_init()

Current blinking rate is calculated based on the difference between
current tx/rx byte counts and priv->led_tpt.

priv->led_tpt should not get reset in iwl_leds_init(), this function can be
called by bring interface "up" or "down", or when uCode sysassert occurred.
resetting the led_tpt parameter will introduce incorrect led blinking behavior.

iwlwifi: print limited number of event log when uCode error

To help iwlagn uCode debugging, event log will dump to syslog when driver
detect uCode error occurred, but this only happen when compile with
CONFIG_IWLWIFI_DEBUG and debug flag is enabled; which is not always
the case. Also, there is another problem, if the flag is set, the entire
event log buffer will be dump to syslog, it can flood the syslog and
make it very difficult to debug the problem.

Change the default to only dump last 20 entries of event log to syslog
unless the following condition meets:
1. both compile with CONFIG_IWLWIFI_DEBUG and debug flag
is enabled, and then dump the entire event buffer to syslog.
2. dump event log request from debugfs

iwlwifi: Tell the ucode immediately when association state changes

When we get a state change of associated or not, we need to tell the
ucode via the RX_ON command using the filter flags.  This will prevent
the ucode from sending any packets when not associated, specifically not
sending NULL QOS packets after a deauthentication which causes the AP to
repeatedly send deauth's in some situations.
