that do not explicitly state this capability (using flag IEEE80211_C_RAWCTL).
also, perform all the sanity checks on injected raw 802.11 frames earlier
(in ieee80211_output instead of ieee80211_encap).
prevent kernel panics with many drivers when running aircrack-ng.
when/if all drivers are capable, we can remove this C_RAWCTL flag.

the SA Query Transaction Identifier field is now a 16-bit non-negative
counter value instead of a 128-bit random value.

field in (Re)Association Requests.
This fixes association with APs refusing non-short-slot-time capable STAs.
This should also prevent the AP we're associating with to disable the use
of short slot time in the BSS as we join.
Fix debug message in recv_assoc_resp() while I'm here (s/reason/status/).
Scary.
Thanks to Adam Emanuel for spotting this.

Maintain state for both originator and recipient roles separately.
Do not allocate receive reordering buffer in addba_request().
Test the "initiator" bit in incoming DELBA frames and set it appropriately
in outgoing DELBA frames.
Separate callbacks for Tx/Rx too.
no binary change since all this is #ifdef'ed out.
|

this reduces memory footprint and avoids a stack usage warning in
ieee80211_find_node() that breaks amd64 build.

- implement A-MPDU frames buffering and reordering
- implement A-MSDU decapsulation
- process/send ADDBA Request, ADDBA Response and DELBA action frames
- process Block Ack Request control frames (including MTBAR)
- implement PBAC support (Protected Block Ack)
- add some incomplete HT Capabilities and HT Operation IEs parsing
Add more Management Frame Protection bits based on 802.11w Draft 7.0:
- implement SA Query procedure (both AP and STA)
- cleanup BIP
Fix some bugs:
- fix check for WEP key length that otherwise caused a stack smash in
ieee80211_wep_encrypt (pointed out by Xavier Santolaria on macppc)
- properly stop EAPOL timeout: fixes a panic that occured in HostAP mode
when turning the interface down while a 4-way handshake is in progress
(pointed out by Doughertys)
Did some code cleanup too.
The HT bits are currently not compiled in (IEEE80211_NO_HT is defined)
because they won't be ready until after the next release and I didn't
want to grow the kernel or to inadvertently introduce new bugs.
They are here such that other people can look at the code.
Notice that I had to add an extra parameter to ic_send_mgmt() for
action frames, that is why there are small changes in drivers defining
their own ic_send_mgmt() handler.
Sorry for the not very incremental diff but this has been sitting in
my tree for too long now.

This will be required for future WPA-Enterprise support (802.1X).
Add ieee80211_needs_auth() function (not implemented yet) to
notify the userland 802.1X PACP machine when an 802.1X port
becomes enabled (that is after successfull 802.11 Open System
authentication).
Add SIOCS80211KEYRUN and SIOCS80211KEYAVAIL ioctls so that the
PACP state machine can kick the 802.11 key state machine and
install PMKs obtained from 802.1X (pre-)authentication.
Enable SHA-256 based AKMPs by default while I'm here (TGw).
This uses SHA-256 for key-derivation (instead of SHA1), AES-128-CMAC
for data integrity, and AES Key Wrap for data protection of EAPOL-Key
frames. An OpenBSD AP will always advertise this capability and an
OpenBSD STA will always prefer SHA-256 based AKMPs over SHA1 based
ones if both are supported by an AP.

header fields (Sequence Control, Address 4, QoS Control, +HTC) and
use them where appropriate.
Add ieee80211_get_qos() inline function to extract the QoS control
field of an 802.11 header instead of duplicating the same scary
code everywhere (the location of this field depends on the presence
of an Address 4 field).
Export ieee80211_up_to_ac() so that drivers can select the access
category to use based on the TID subfield of the QoS Control field.
Define more QoS-related bits for the RSN Capabilities field of RSN IE
(will be used later).

subtype, not a boolean indicating assoc or reassoc.
rename the parameter and use if (type == IEEE80211_FC0_SUBTYPE_REASSOC_REQ)
instead of if (reassoc).
it worked only because IEEE80211_FC0_SUBTYPE_ASSOC_REQ is equal to 0.

0=normal ack). all bits are currently set to 0.
use this bitmap to set the ACK policy of the QoS control field of
outgoing QoS frames.

ieee80211_mgmt_output() and ieee80211_encap().
use new IEEE80211_C_APPMGT capability flag where appropriate.
rename ic_tim_mcast to ic_tim_mcast_pending.

to the Attic. nothing uses it in the tree and it is very unlikely
that something will use it one day.
the only driver supporting FHSS PHYs in the tree is ray(4) and it
does not use net80211.
|
|
remove IBSS and HostAP support from net80211 and 802.11 drivers.
it can be used to shrink RAMDISK kernels for instance (like what
was done for wi(4)).
it also has the benefit of highlighting what is specific to IBSS
and HostAP modes in the code.
the cost is that we now have two code paths to maintain.

from MMIE etc...
this code can't be triggered as no drivers claim MFP capability yet.
|
|
|
|
add support for MFP negotiation during association.
|
|
instead of hard-coding values.
for RSN IE, request space for Group Integrity Cipher Suite.
|
|
wrong. hard-code 0xf for now. will be fixed post-release.
|
|
copy m_pkthdr.len and m_flags before and use that after to update
the statistics.
from altq(4) man page and for consistency with what is done in
other parts of the tree.

WPA is on and RX protection for TA is on.
Keep track of the TX/RX protection for each node when WPA is on.
tested by djm@ (ral+wpa), ckuethe@ (ath-noenc) and krw@ (wpi<->ral+wpa).
hints from bluhm@
has been in snaps for a few days.
pointed out by bluhm@ something like 1 year ago but we did not have
the right infrastructure to fix it properly at that time.

automatically prepend __func__ to output.
deobfuscates debug messages a bit.
no binary change unless compiled with IEEE80211_DEBUG.

The bug was added on 04/16 but it started to show up only after 06/12 when
the value of MINCLSIZE was changed to something different from MHLEN + 1.
Thanks to dlg@ and giovanni (qgiovanni at gmail dot com) for putting me
on the right track.
Tested by giovanni.
Should fix system/5881 too.

this must not be included by drivers.

handshake protocols (both supplicant and authenticator state
machines) as defined in the IEEE 802.11i standard.
Software implementation of the TKIP (Temporal Key Integrity
Protocol) and CCMP (CTR with CBC-MAC Protocol) protocols.
This diff doesn't implement any of the 802.1X authentication
protocols and thus only PSK authentication (using pre-shared
keys) is currently supported.
In concrete terms, this adds support for WPA-PSK and WPA2-PSK
protocols, both in station and hostap modes.
The following drivers are marked as WPA-capable and should
work: bwi(4), malo(4), ral(4), iwn(4), wpi(4), ural(4),
rum(4), upgt(4), and zyd(4)
The following options have been added to ifconfig(8):
wpa, wpapsk, wpaprotos, wpaakms, wpaciphers, wpagroupcipher
wpa-psk(8) can be used to generate keys from passphrases.
tested by many@

add some RSNA authenticator state machine bits.
|
|
message 2/4 of the 4-way handshake because the authenticator must
derive the PTK first (the MIC is computed using the KCK).
Move calls to ieee80211_eapol_key_check_mic() - and as a consequence
ieee80211_eapol_key_decrypt() - directly in the
ieee80211_recv_{group,4way}_msg*() functions.
Unconstify the first parameter since checking the MIC modifies the
frame. Remove ni->ni_ptk_ok field while i'm here.
|

Tx/Rx MIC for TKIP.
- add two functions to map a PTK and a GTK to an IEEE 802.11 key and
use them in ieee80211_input.c instead of duplicating the same code.
properly set Tx/Rx MIC in the IEEE 802.11 key in the case of TKIP.
- add ic_psk to struct ieee80211com to store the pre-shared key.
- fix setting of the SECURE bit in outgoing EAPOL-Key frames.
- when receiving msg 2 of the 4-way handshake, deauthenticate the
station if the RSN IE does not match that of the (Re)Association
request.
- before parsing an RSN or WPA IE, check that there's enough room for
the version field (2 bytes) which is mandatory.
- various tweaks while i'm here.
|

Even no bit was set we copied the full 225bytes bitmaks into the beacon.
Found the hard way with acx(4) by mglocker@ and myself.
OK mglocker@ damien@

a station is using WPA1 or RSN descriptors.
make sure that a station that advertises WPA1 capability in an IE
uses the WPA1 EAPOL-Key descriptor type and not the RSN one.
fix construction of EAPOL-Key frames for WPA1.
i can now successfuly complete a 4-way and group-key handshake
with both a WPA1 and a WPA2 access point.
add some TKIP encapsulation code (no SW crypto yet).
ok deraadt@

4-way handshake to ieee80211_send_4way_msg2().
|
|
|
|
this simplifies ieee80211_eapol_key_mic() and ieee80211_eapol_key_check_mic()
quite a bit.
set the EAPOL-Key body length before computing the MIC since the MIC is
computed with the 802.1X header too.
add a missing htons() while i'm here.
|
|
|
|
the 4-way and group-key handshake.
the state machine is still missing though so this is not used
anywhere yet.
|
|
add a parameter to ieee80211_decap() to handle different 802.11
header sizes.
cleanup and clarify ieee80211_classify().
|
|
ieee80211_get_cts_to_self() if mbuf allocation fails.
|
|
still very ugly but hopefully correct.
|
|
it has been #if 0'd since 3.9 and we have never supported this mode (no
ifconfig option etc...).
|
|
fixes my 1.36 commit (the bit should not be set for non-AP STA
only in Probe Responses and Beacons).
|
|
needed or not to the callers (instead of doing nothing in add_xrates).
|
|
vendor-specific IE.
|
|
add RSN IE to beacons, probe responses and (re)association requests.
|
|
a default ieee80211_set_tim() function that drivers can override
by setting ic_set_tim.
