tcp: fix retrans_stamp advancing in error cases
It can happen, that tcp_retransmit_skb fails due to some error.
In such cases we might end up into a state where tp->retrans_out
is zero but that's only because we removed the TCPCB_SACKED_RETRANS
bit from a segment but couldn't retransmit it because of the error
that happened. Therefore some assumptions that retrans_out checks
are based do not necessarily hold, as there still can be an old
retransmission but that is only visible in TCPCB_EVER_RETRANS bit.
As retransmission happen in sequential order (except for some very
rare corner cases), it's enough to check the head skb for that bit.
Main reason for all this complexity is the fact that connection dying
time now depends on the validity of the retrans_stamp, in particular,
that successive retransmissions of a segment must not advance
retrans_stamp under any conditions. It seems after quick thinking that
this has relatively low impact as eventually TCP will go into CA_Loss
and either use the existing check for !retrans_stamp case or send a
retransmission successfully, setting a new base time for the dying
timer (can happen only once). At worst, the dying time will be
approximately the double of the intented time. In addition,
tcp_packet_delayed() will return wrong result (has some cc aspects
but due to rarity of these errors, it's hardly an issue).
One of retrans_stamp clearing happens indirectly through first going
into CA_Open state and then a later ACK lets the clearing to happen.
Thus tcp_try_keep_open has to be modified too.
Thanks to Damian Lukowski <damian@tvk.rwth-aachen.de> for hinting
that this possibility exists (though the particular case discussed
didn't after all have it happening but was just a debug patch

tcp: Stalling connections: Fix timeout calculation routine
This patch fixes a problem in the TCP connection timeout calculation.
Currently, timeout decisions are made on the basis of the current
tcp_time_stamp and retrans_stamp, which is usually set at the first
retransmission.
However, if the retransmission fails in tcp_retransmit_skb(),
retrans_stamp is not updated and remains zero. This leads to wrong
decisions in retransmits_timed_out() if tcp_time_stamp is larger than
the specified timeout, which is very likely.
In this case, the TCP connection dies after the first attempted
(and unsuccessful) retransmission.
With this patch, tcp_skb_cb->when is used instead, when retrans_stamp
is not available.
This bug has been introduced together with retransmits_timed_out() in
2.6.32, as the number of retransmissions has been used for timeout
decisions before. The corresponding commit was

net/mpc5200: Fix locking on fec_mpc52xx driver
Fix the locking scheme on the fec_mpc52xx driver. This device can
receive IRQs from three sources; the FEC itself, the tx DMA, and the
rx DMA. Mutual exclusion was handled by taking a spin_lock() in the
critical regions, but because the handlers are run with IRQs enabled,
spin_lock() is insufficient and the driver can end up interrupting
a critical region anyway from another IRQ.
Asier Llano discovered that this occurs when an error IRQ is raised
in the middle of handling rx irqs which resulted in an sk_buff memory
leak.
In addition, locking is spotty at best in the driver and inspection
revealed quite a few places with insufficient locking.
This patch is based on Asier's initial work, but reworks a number of
things so that locks are held for as short a time as possible, so
that spin_lock_irqsave() is used everywhere, and so the locks are
dropped when calling into the network stack (because the lock only
protects the hardware interface; not the network stack).

ath9k: fix tx status reporting
This patch fixes a bug in ath9k's tx status check, which
caused mac80211 to consider regularly transmitted unicast frames
as un-acked.
When checking the ts_status field for errors, it needs to be masked
with ATH9K_TXERR_FILT, because this field also contains other fields
like ATH9K_TX_ACKED.
Without this patch, AP mode is pretty much unusable, as hostapd
checks the ACK status for the frames that it injects.

On a 32-bit machine, BIT() macro does not give the required
bit value if the bit is mroe than 31. In ieee802_11_parse_elems_crc(),
BIT() is suppossed to get the bit value more than 31 (42 (id of ERP_INFO_IE),
37 (CHANNEL_SWITCH_IE), (42), 32 (POWER_CONSTRAINT_IE), 45 (HT_CAP_IE),
61 (HT_INFO_IE)). As we do not get the required bit value for the above

mwl8k: increase firmware loading timeouts
The time between loading the helper image and starting to upload the
main firmware image should be at least 5 ms or so. We were doing an
msleep(1) before, and 1 ms appears to not be enough in almost all
cases, but building with HZ=100 has always masked this so far. Bumping
the msleep argument to 5 fixes firmware loading e.g. when HZ=1000.
Some firmware images need more than 200ms to initialize. Bump the
ready code timeout to 500ms to accommodate for this.

mwl8k: allow more time for transmit rings to drain
Before issuing any firmware commands, we wait for the transmit rings
to drain, to prevent control versus data path synchronization issues.
In some cases, this can end up taking longer than the current hardcoded
limit of 5 seconds, for example if the transmit rings are filled with
packets for a host that has dropped off the air and we end up
retransmitting every pending packet at the lowest rate a couple of
times.
This patch changes mwl8k_tx_wait_empty() to only bail out on timeout
expiry if there was no change in the number of packets pending in the
transmit rings during the waiting period. If at least one transmit
ring entry was reclaimed while we were waiting, we are apparently still
making progress, and we'll allow waiting for another timeout period.

mwl8k: fix addr4 zeroing and payload overwrite on DMA header creation
When inserting a DMA header into a packet for transmission,
mwl8k_add_dma_header() would blindly zero the addr4 field, which
is not a good idea if the packet being transmitted is actually a
4-address packet.
Also, if the transmitted packet was a 4-address with QoS packet,
the memmove() to do the needed header reshuffling would inadvertently
overwrite the first two bytes of the packet payload with the QoS field.
This fixes both of these issues.

mwl8k: prevent corruption of QoS field on receive
Packets exchanged between the mwl8k driver and the firmware always
have a 4-address header without QoS field. For QoS packets, the QoS
field is passed to/from the firmware via the tx/rx descriptors.
We were handling this correctly on transmit, but not on receive -- if
a QoS packet was received, we would leave garbage in the QoS field in
the packet passed up to the stack, which is Bad(tm).
Also, if the packet received on the air was a 4-address without QoS
packet, we would forget to skb_pull the 2-byte DMA length prefix off.
This patch adds an argument to the ->rxd_process() receive descriptor
operation to retrieve the QoS field from the receive descriptor, and
extends mwl8k_remove_dma_header() to insert this field back into the
packet if the packet received is a QoS packet. It also fixes
mwl8k_remove_dma_header() to strip off the length prefix in all cases.

mwl8k: fix UPDATE_STADB command struct legacy_rates array length
There exist 12 802.11b/g rates, but mwl8k supports two additional
(non-standard) rates, and includes those rates in rate bitmasks and
in its internal rate table that hardware rate indices index.
Commit "mwl8k: report rate and other information for received frames"
added one of the nonstandard rates to the mwl8k_rates table to make
the OFDM rates in the table line up with the rate indices that are
reported in the receive descriptor (so that we can just simply copy
the receive descriptor rate index into ieee80211_rx_status::rate_idx)
and bumped MWL8K_IEEE_LEGACY_DATA_RATES from 12 to 13, but this
screwed up the UPDATE_STADB command struct layout, as it also uses
that define, for its legacy_rates array.
To avoid having to convert rate indices and legacy rate bitmaps (e.g.
ieee80211_bss_conf::basic_rates) between the 12-rate mac80211 format
and the 14-rate mwl8k format, we'll report all 14 rates in our wiphy's
band, but filter out the nonstandard ones e.g. in the case of the
UPDATE_STADB command which only accepts 12 rates.
In the commands that accept 14 rates (SET_AID, SET_RATE), replace the
use of the MWL8K_RATE_INDEX_MAX_ARRAY define in the command struct by
the constant 14, to make it clearer that these commands accept 14 rates.
