Alex Sidorenko reported:
"while experimenting with 'netem' we have found some strange behaviour. It
seemed that ingress delay as measured by 'ping' command shows up on some
hosts but not on others.
After some investigation I have found that the problem is that skbuff->tstamp
field value depends on whether there are any packet sniffers enabled. That
is:
- if any ptype_all handler is registered, the tstamp field is as expected
- if there are no ptype_all handlers, the tstamp field does not show the delay"
This patch prevents unnecessary update of tstamp in dev_queue_xmit_nit()
on ingress path (with act_mirred) adding a check, so minimal overhead on
the fast path, but only when sniffers etc. are active.
Since netem at ingress seems to logically emulate a network before a host,
tstamp is zeroed to trigger the update and pretend delays are from the
outside.

The Broadcom chips with 2.1 firmware handle the fallback case to a SCO
link wrongly when setting up eSCO connections.
< HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17
handle 11 voice setting 0x0060
> HCI Event: Command Status (0x0f) plen 4
Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1
> HCI Event: Connect Complete (0x03) plen 11
status 0x00 handle 1 bdaddr 00:1E:3A:xx:xx:xx type SCO encrypt 0x01
The Link Manager negotiates the fallback to SCO, but then sends out
a Connect Complete event. This is wrong and the Link Manager should
actually send a Synchronous Connection Complete event if the Setup
Synchronous Connection has been used. Only the remote side is allowed
to use Connect Complete to indicate the missing support for eSCO in
the host stack.
This patch adds a workaround for this which clearly should not be
needed, but reality is that broken Broadcom devices are deployed.

Some Bluetooth chips (like the ones from Texas Instruments) don't do
proper eSCO negotiations inside the Link Manager. They just return an
error code and in case of the Kyocera ED-8800 headset it is just a
random error.

In these cases it is up to the host stack to fallback to a SCO setup
and so retry with SCO parameters.

The removal of the SAME target accidentally removed one feature that is
not available from the normal NAT targets so far, having multi-range
mappings that use the same mapping for each connection from a single
client. The current behaviour is to choose the address from the range
based on source and destination IP, which breaks when communicating
with sites having multiple addresses that require all connections to
originate from the same IP address.
Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the
destination address is taken into account for selecting addresses.

Wext makes no assumptions about the contents of
data->txpower.fixed and data->txpower.value when
data->txpower.disabled is set, so do not update
the user-requested power level while disabling.
Also, when wext configures a really _fixed_ power
output [1], we should reject it instead of limiting it
to the regulatory constraint. If the user wants to set
a _limit_ [2] then we should honour that.

Currently rx status for frames which are completed from reorder buffer
is taken from it's cb area which is not always right, cb is not holding
the rx status when driver uses mac80211's non-irq rx handler to pass it's
received frames. This results in dropping almost all frames from reorder
buffer when security is enabled by doing double decryption (first in hw,
second in sw because of wrong rx status). This patch copies rx status into
cb area before the frame is put into reorder buffer. After this patch,
there is a significant improvement in throughput with ath9k + WPA2(AES).

Conflict in firmware/WHENCE (SCSI vs net firmware)
If an ipv4 packet (not locally generated with IP_DF flag not set) bigger
than mtu size is supposed to go via a xfrm ipv6 tunnel, the packetsize
check in xfrm4_tunnel_check_size() is omited and ipv6 drops the packet
without sending a notice to the original sender of the ipv4 packet.
Another issue is that ipv4 connection tracking does reassembling of
incomming fragmented packets. If such a reassembled packet is supposed to
go via a xfrm ipv6 tunnel it will be droped, even if the original sender
did proper fragmentation.
According to RFC 2473 (section 7) tunnel ipv6 packets resulting from the
encapsulation of an original packet are considered as locally generated
packets. If such a packet passed the checks in xfrm{4,6}_tunnel_check_size()
fragmentation is allowed according to RFC 2473 (section 7.1/7.2).
This patch sets skb->local_df in xfrm6_prepare_output() to achieve
fragmentation in this case.
