f72750896c nl80211: Add verbose result debugging for NL80211_CMD_NEW_STATION 2009-03-05 11:24:48 +02:00

3ae0800c5f WMM cleanup (WME -> WMM rename, comments, etc.)
This updates the terminogy to match with the final WMM specification. In
addition, some of the WMM TSPEC structure fields were in incorrect order
and used without byte order swapping. Those are also taken care of this
cleanup patch.

dbdf58b053 driver_nl80211: Fix STA accounting data collection
TX/RX bytes are now reported correctly (typo ended up leaving TX bytes
uninitialized and set RX bytes value to use correct TX bytes). TX/RX
packet counts are not yet available from kernel, so we have to clear the
values to avoid reporting bogus data.

42f1ee7d1f Fixed scan buffer increasing with WEXT
We can now handle up to 65535 byte result buffer which is the maximum
due to WEXT using 16-bit length field. Previously, this was limited to
32768 bytes in practice even through we tried with 65536 and 131072
buffers which we just truncated into 0 in the 16-bit variable.

This more or less doubles the number of BSSes we can received from scan
results.

5eb4e3d024 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
Try to match PRI/SEC channel with neighboring 20/40 MHz BSSes per
IEEE 802.11n/D7.0 11.14.3.2. This is not yet complete implementation,
but at least some parts of the 40 MHz coex are improved.

40 MHz operation maybe rejected (i.e., fall back to using 20 MHz) or
pri/sec channels may be switched if needed.

f01a6b1e3e driver_nl80211: Fixed inactivity poll status processing
Previous version was discarding TX status for FromDS data frames, but
those are the exact ones that we need to check for inactivity poll to
work, i.e., they are TX status reports for injected data frames.

In addition, remove the debug printing of TX status for data frame since
that could fill up the debug output if kernel-side filtering cannot be
used with monitor interface.

9616af520b driver_nl80211: use Linux socket filter to improve performance
TX status information for all transmitted data frames is not going to
be sent to hostapd anymore, so the CPU load with high traffic load is
going to be significantly reduced.

bfddd95c9e Split hostapd/driver.h into two files

d5263983ac MFP: Remove mac80211 workaround of IGTK in monitor netdev
mac80211 can now figure out which key to use for injected frames (in
most cases), so we can remove the workaround for configuring IGTK on the
monitor interface that is used for injecting frames.

205a372b2d Added libnl 2.0 compatibility code (CONFIG_LIBNL20=y in .config needed)
Unfortunately, at least the current libnl git snapshot changes the API
in backwards incompatible way and in a way that makes it difficult to
to allow building against the latest libnl code.

used.

bb9f45e0bb nl80211: Remove the debug print from data frame processing
This is currently happening way too frequently (mac80211 monitor
interface sends TX info for every frame) and the end result makes it
difficult to read hostapd debug log if there is large amount of data
traffic.

4a7b9f885f Fixed WEP authentication (both Open System and Shared Key) with mac80211
Only one of the authentication frame types is encrypted. In order for
static WEP encryption to work properly (i.e., to not encrypt the frame),
we need to tell mac80211 about the frames that must not be encrypted.

f07688e37d nl80211: Generate 802.11b mode based on 802.11g information
If the phy info from nl80211 does not include 802.11b mode, generate
that mode based on 802.11g information. This allows hw_mode=b to be used
with drivers that support 2.4 GHz band.

This depends on a patch to Linux nl80211/mac80211 that has not yet been
merged into wireless-testing. If that change is not present, the old
mechanism (WEXT) will be used instead.

d6c9d4740b driver_nl80211: Added set_country() handler
If country_code is set in hostapd.conf, hostapd will now update nl80211
regulatory data by setting the alpha2 string for CRDA. In other words,
"iw reg set <alpha2>" is not needed anymore when using hostapd.

Jouni Malinen
10b83bd712 Changed channel flags configuration to read the information from the driver
(e.g., via driver_nl80211 when using mac80211) instead of using hostapd as
the source of the regulatory information (i.e., information from CRDA is
now used with mac80211); this allows 5 GHz channels to be used with hostapd
(if allowed in the current regulatory domain).

6773de39b1 nl80211 driver: correctly set the encrypt bit for eapol frames
A recent kernel change led to all EAPOL frames being encrypted rather than
just those for the group handshake. This is due to transmit processing in
the kernel now using the proper interface which would encrypt those frames
with the group key because hostapd wasn't requesting that they not be
encrypted. This changes the nl80211 driver to not request encryption unless
the EAPOL frame should be encrypted.

9b71728bba Cleaned up TX callback request processing
Move the use of 802.11 header protocol field into driver_hostap.c since
this is a Host AP driver specific mechanism and other driver wrappers
should not really need to know about it.

This new cfg80211 command is used for setting CTS protect, short preamble,

been submitted, but is not yet included in wireless-testing. The code here
used #ifdef to avoid compilation failures before the new command is

been approved. The new commands can be enabled by defining
NL80211_MFP_PENDING (this will be removed once the API changes is
