wext: fix alignment problem in serializing 'struct iw_point'
wext: fix alignment problem in serializing 'struct iw_point'
This fixes a typo in the definition of the serialized length of struct iw_point:
a) wireless.h is exported to userspace, the typo causes IW_EV_POINT_PK_LEN
to be 12 on 64-bit, and 8 on 32-bit systems (causing misalignment);
b) in compat-64 mode iwe_stream_add_point() memcpys overlap (see below).
The second case in in compat-64 mode looks like (variable names are as in
include/net/iw_handler.h:iwe_stream_add_point()):
point_len = IW_EV_COMPAT_POINT_LEN = 8
lcp_len = IW_EV_COMPAT_LCP_LEN = 4
2nd memcpy: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 12 - 4 = 8
IW_EV_LCP_PK_LEN
<--------------> *---> 'extra' data area
+-------+-------+-------+-------+---------------+------- ...-+
| len | cmd |length | flags | (empty) -> extra ... |
+-------+-------+-------+-------+---------------+------- ...-+
2 2 2 2 4
lcp_len
<--------------> <-!! OVERLAP !!>
<--1st memcpy--><------- 2nd memcpy ----------->
<---- 3rd memcpy ------- ... >
<--------- point_len ---------->
This case could cause overrun whenever iw_point.length < 4.
The other two cases are -
* 32-bit systems: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 8 - 4 = 4,
the second memcpy copies exactly the 4 required bytes;
* 64-bit systems: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 12 - 4 = 8,
the second memcpy copies a superfluous (but non overlapping) 4 bytes.
The patch changes IW_EV_POINT_PK_LEN to be 8, so that in all 3 cases always only
the requested iw_point.{length,flags} (both __u16) are copied, avoiding overrrun
(compat-64) and superfluous copy (64-bit). In addition, the userspace header is
sanitized (in agreement with version 30 of the wireless tools).

ath9k: A-MPDU rate control info fix
This patch fixes the following problems with the rate control feedback
generated by ath9k for A-MPDU frames:
1. Rate control feedback is carried on the first frame of an aggregate
that is either ACKed, or has execeeded the software retry count and is
considered failed. However, ath9k would incorrectly assume the aggregate
had the length 1 if one of these conditions did not apply to the first
frame of the aggregate, but instead a later frame. This fix therefor
copies the bf_nframes field of the buffer in the same manner as the rates
field of the tx status.
2. Sometimes the ampdu_len and ampdu_ack_len fields of the tx status was
left uninitialized eventhough the IEEE80211_TX_STAT_AMPDU flag was set.
This is now avoid by setting flag and fields in the same place.
3. Even if a frame has been selected for aggregation by mac80211 and
marked with the IEEE80211_TX_CTL_AMPDU flag it can sometimes happen that
ath9k transmits the frame without aggregation. In these cases the
ampdu_ack_len field could be incorrectly computed because the nbad
parameter to ath_tx_rc_status was incorrect.

mac80211: minstrel_ht A-MPDU fix
This patch fixes two problems with the minstrel_ht rate control
algorithms handling of A-MPDU frames:
1. The ampdu_len field of the tx status is not always initialized for
non-HT frames (and it would probably be unreasonable to require all
drivers to do so). This could cause rate control statistics to be
corrupted. We now trust the ampdu_len and ampdu_ack_len fields only when
the frame is marked with the IEEE80211_TX_STAT_AMPDU flag.
2. Successful transmission attempts where only recognized when the A-MPDU
subframe carrying the rate control status information was marked with the
IEEE80211_TX_STAT_ACK flag. If this information happed to be carried on a
frame that failed to be ACKed then the other subframes (which may have
succeeded) where not correctly registered. We now update rate control
statistics regardless of whether the subframe carrying the information was
ACKed or not.

This patch updates IEEE802.11 mesh constants to be consistent with newly

A few notes are in order:
1. This will break backwards compatibility with existing Linux kernels as
over-the-air constants have changed.
2. Some old and obsolete constants have been retained for now as the mesh code
itself hasn't been updated yet to the new 802.11s draft. This was desired to
keep the existing mesh scheme working until it can be updated. Adding the
approved values is the first step in updating the mesh code.

The iwl_dump_csr function is only used

iwlwifi: remove spurious exports
A number of exports, especially related to
thermal throttling, are unnecessary because
the code lives in the same module that it
is used in, so remove them.

The code to print out TX failure reasons is

iwlwifi: move agn specific station code there
By duplicating a little bit of code between 3945
and agn, we can move a lot of code into an agn
specific station management file and thus reduce
the amount of code in core that is dead to 3945.
before:
text data bss dec hex filename
212886 3872 96 216854 34f16 iwlcore.ko
620542 10448 304 631294 9a1fe iwlagn.ko
314013 3264 196 317473 4d821 iwl3945.ko
after:
text data bss dec hex filename
202857 3872 92 206821 327e5 iwlcore.ko
629102 10448 308 639858 9c372 iwlagn.ko
314240 3264 196 317700 4d904 iwl3945.ko
delta:
-10029 iwlcore.ko
8560 iwlagn.ko
227 iwl3945.ko
so it's a net win even if you have both loaded,
likely because a lot of EXPORT_SYMBOLs go away.
