The last bit written to a completion descriptor by hardware is the color
bit. Driver must read all other descriptor fields only after reading the
color bit to avoid reading stale descriptor fields. There is a rmb() after
reading the color bit to avoid any compiler/cpu reordering of the reads.
The color bit is the generation bit that toggles each pass through the
completion descriptor ring.

IEEE 802.3ae clause 45 specifies a somewhat modified MDIO protocol
for use by 10GIGE phys. The main change is a 21 bit address split into
a 5 bit device ID and a 16 bit register offset. The definition is designed
so that normal and extended devices can run on the same MDIO bus.
Extend mdio-bitbang to do the new protocol. At the MDIO bus level the
protocol is requested by or'ing MII_ADDR_C45 into the register offset.
Make phy_read/phy_write/etc pass a full 32 bit register offset.
This does not attempt to make the phy layer support C45 style PHYs, just
to provide the MDIO bus support.

This patch fixes UDP socket refcnt bugs in the pppol2tp driver.
A bug can cause a kernel stack trace when a tunnel socket is closed.
A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is
Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
pppol2tp_recv_core: sock_hold()
pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
pppol2tp_recv_core: sock_hold()
pppol2tp_recv_core: sock_put
Close tunnel management socket
pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
udp_lib_close: BUG
The addition of sock_hold() in pppol2tp_connect() solves the problem.
For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.

When I initially stumbled upon sequence number problems with PAE frames
in ath9k, I submitted a patch to remove all special cases for PAE
frames and let them go through the normal transmit path.
Out of concern about crypto incompatibility issues, this change was
merged instead:
commit 6c8afef551
Author: Sujith <Sujith.Manoharan@atheros.com>
Date: Tue Feb 9 10:07:00 2010 +0530
ath9k: Fix sequence numbers for PAE frames
After a lot of testing, I'm able to reliably trigger a driver crash on
rekeying with current versions with this change in place.
It seems that the driver does not support sending out regular MPDUs with
the same TID while an A-MPDU session is active.
This leads to duplicate entries in the TID Tx buffer, which hits the
following BUG_ON in ath_tx_addto_baw():
index = ATH_BA_INDEX(tid->seq_start, bf->bf_seqno);
cindex = (tid->baw_head + index) & (ATH_TID_MAX_BUFS - 1);
BUG_ON(tid->tx_buf[cindex] != NULL);
I believe until we actually have a reproducible case of an
incompatibility with another AP using no PAE special cases, we should
simply get rid of this mess.
This patch completely fixes my crash issues in STA mode and makes it
stay connected without throughput drops or connectivity issues even
when the AP is configured to a very short group rekey interval.

The rate control algorithm, default is Minstrel for ath5k, determines
the number of retries to use for each rate. However, there exists in
ath5k_hw_setup_4word_tx_desc (which is called for AR5212 like devices)
a set number of retries defined by AR5K_TUNE_HWTXTRIES. The set
number of tries is added to the tx_tries0 variable setup by the rate
control algorithm. This changes the number of retries the rate
control algorithm considers necessary. By removing the
AR5K_TUNE_HWTXTRIES from the retry calculation the rate control
algorithm is given control over the number of retries.

Currently the rate control tx status update gets called for every
subframe of an A-MPDU, and ath9k marks the frame with the relevant
status update with an internal flag. This not suitable for rate control
algorithms using the standard mac80211 rate control API, so fix this by
using IEEE80211_TX_STAT_AMPDU for marking the correct frames that
should be processed.

Currently, the padding position is based on
ieee80211_get_hdrlen_from_skb(). This is not correct since the HW does
padding on RX (and expect the same padding to be present on TX) at the
following position :
- management : 24 + 6 if 4-addr format
- control : 24 + 6 if 4-addr format
- data : 24 + 6 if 4-addr format + 2 if QoS
- invalid : 24 + 6 if 4-addr format
whereas ieee80211_get_hdrlen_from_skb() is :
- management : 24
- control : 16 except for ACK/CTS where it is 10
- data : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order
- invalid : 24
So, correct frames are not affected : management frames do not use
4-addr format, control frames have no body and invalid frames are ...
not valid by definition. However, in order to use monitor interface for
debugging purpose, one must be able to send/receive any frames, be it
correct or not. Such frames are affected by incorrect padding.
Moreover, since padding is added on TX, we need to remove it before
calling ieee80211_tx_status. This affect TX packets received by monitor
interfaces.
It has been tested between an ath5k based card (AR5212) and an ar9170usb
based card (netgear WNDA3100) using a frame generator and a monitor
interface for each card.

I/Q calibration was completely broken, resulting in a high number of CRC errors
on received packets. before i could see around 10% to 20% CRC errors, with this
patch they are between 0% and 3%.
1.) the removal of the mask in commit "ath5k: Fix I/Q calibration
(f1cf2dbd0f)" resulted in no mask beeing used
when writing the I/Q values into the register. additional errors in the
calculation of the values (see 2.) resulted too high numbers, exceeding the
masks, so wrong values like 0xfffffffe were written. to be safe we should
always use the bitmask when writing parts of a register.
2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we
convert to a signed value later by substracting 128. this resulted in too low
numbers for Q many times, which were limited to -16 by the boundary check later
on.
3.) checked everything against the HAL sources and took over comments and minor
optimizations from there.
4.) we can't use ENABLE_BITS when we want to write a number (the number can
contain zeros). also always write the correction values first and set ENABLE
bit last, like the HAL does.

when using a fixed antenna we should use the antenna number in all tx
descriptors, otherwise the hardware will sometimes send the frame out on the
other antenna. it seems like the hardware does not always respect the default
antenna and diversity settings (esp. AR5K_STA_ID1_DEFAULT_ANTENNA).
also i would like to note that antenna diversity does not always work correctly
on 5414 (at least) when only one antenna is connected: for example all frames
might be received on antenna A but still the HW tries to send on antenna B some
times, causing packet loss.
this is both verified with the antenna statistics output of the previous patch

Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory
corruption problem. When initializing the clip groups the code was
mistakenly using the iwlagn rate count, not the 3945 rate count. This
resulted in more memory being written than was allocated.
"iwlwifi: move 3945 clip groups to 3945 data" moved the location where the
clip groups are stored and the impact is now severe in that the number of
configured TX queues is modified. Previously the
"temperature" field was overwritten, which did not seem to affect the
operation.
Fix this one instance where wrong rate count was used. I also noticed one
more location where the iwlagn rate count was used to index an iwl3945
array, fix this. I also modified one location that modified the iwlagn rate
count to obtain the iwl3945 rate count ... just use the iwl3945 rate count
directly.

Introduce a new IWL_TX_FIFO_UNUSED constant

code to reserve all queues in the arrays

Additionally, clear up the AC/queue mapping

All the ICT ISR code is iwlagn specific, and doesn't
need to be in iwlcore. So create a new iwl-agn.h

* detects/prevents accidental (but not intentional)
modification attempts on archs that enforce
read-only kernel data at runtime
* potentially better optimized code as the compiler

* the compiler/linker move const data into .rodata

Starting with commit a3bc1f11e9 ("gianfar: Revive SKB
recycling") gianfar driver sooner or later stops transmitting any
packets on SMP machines.
start_xmit() prepares new skb for transmitting, generally it does
three things:
1. sets up all BDs (marks them ready to send), except the first one.
2. stores skb into tx_queue->tx_skbuff so that clean_tx_ring()
would cleanup it later.
3. sets up the first BD, i.e. marks it ready.
Here is what clean_tx_ring() does:
1. reads skbs from tx_queue->tx_skbuff
2. checks if the *last* BD is ready. If it's still ready [to send]
then it it isn't transmitted, so clean_tx_ring() returns.
Otherwise it actually cleanups BDs. All is OK.
Now, if there is just one BD, code flow:
- start_xmit(): stores skb into tx_skbuff. Note that the first BD
(which is also the last one) isn't marked as ready, yet.
- clean_tx_ring(): sees that skb is not null, *and* its lstatus
says that it is NOT ready (like if BD was sent), so it cleans
it up (bad!)
- start_xmit(): marks BD as ready [to send], but it's too late.
We can fix this simply by reordering lstatus/tx_skbuff writes.

This behavior changed after the off-channel changes. Now, the channel
is not updated with the new HT params in enable_ht() - instead, it
is now done when the scan work terminates. This results in the driver
depending on stale information, defaulting to non-HT mode always.

At the wireless summit in Portland we discussed a way of
loading firmware asynchronously from ->probe() before
registration to mac80211, in order to register with the
wireless subsystems with complete information in cases
where firmware is required to know parameters.
This is not yet the case in iwlwifi, but for some new
features we're working on it will be the case since
those will only be supported by new firmware images.
Hence, to start with, convert iwlwifi to load firmware
asynchronously from probe, unbinding the device when
firmware loading fails, and only registering with the
wireless subsystems after firmware has been loaded
successfully.
Future patches will hook into this to register the
new firmware capabilities, depending on the firmware
API version.
