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.
|
|
some whitespace cleanup too.

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.

add two capabilities flags: IEEE80211_C_HT for HT STAs (802.11n)
and IEEE80211_C_APPMGT which indicates the capability for an AP
to buffer unicast and multicast traffic for STAs in PS mode.
all drivers claiming HostAP support should support that but the
truth is that none of them do.
most of them are still at the 802.11b-only era and do not update
dynamic parts of beacons or process frames from ic_pwrsaveq.

that ieee80211.h contains only definitions that are part of the
802.11 standard and not constants used internally by net80211.
because channels attributes are exported to userland through the
radiotap BPF interface, add the definitions to ieee80211_radiotap.h
too (which must be kept in sync with what is used in net80211).
also, do not export combinations of channel attributes to userland
so that noone get stupid ideas.
|
|
use it in drivers that leave the 802.11 FCS in frames
passed to radiotap BPF. otherwise, userland has no way
to know if FCS is included or not as it depends on drivers.
this is required by some ports (aircrack).

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.

to a separate ieee80211_deliver_data() function.
this will later be called by the A-MSDU deaggregation routine.

when acting as an access point instead of having each driver doing the
job.
tested by krw@ (ral AP) and me with several drivers.

have a variable length. use LLC_SNAPFRAMELEN instead (which happen
to be equal to sizeof(struct llc)) as we only deal with LLC+SNAP
headers.
some indentation tweaks while i'm here.
no binary change.
|
|
fix a test on the mbuf length and one on the descriptor version.
remove redundant checking of GTK KDE length.

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.
|
|
MIC is computed using AES-128-CMAC instead of HMAC-SHA1).
add a SHA-256 based key derivation function (not used yet).

of the frame so that it is a multiple of 8 bytes before encryption.
So we must reserve up to 15 bytes in the mbuf for the worst case, not 8.
|
|
if MFP was negotiated with the peer (not possible yet).
|
|
indices 0-3 will be used for group data keys while indices 4-5 will
be used for integrity group keys.
add a ic_rsngroupmgmtcipher field too.
|

using CCMP. use the right replay counter in this case.
|
|
Free the mbuf in the ieee80211_eapol_key_input() function.
Do not assume the frame is contiguous, call m_pullup2() if it is not.
We need the frame to be contiguous to process KDEs efficiently in
EAPOL-Key frames (just like we process IEs in management frames).
However, there are drivers like upgt(4) that use m_devget() in the
RX path. m_devget() can return fragmented mbuf chains.
Notice that we should do the same m_pullup2() for management frames.
This will be done later.
Remove the ic_recv_eapol callback.

IEEE80211_KEY_IGTK.
lot of cleanup while i'm here (indent function prototypes).
change license since this file was completely rewritten.

in Draft IEEE P802.11w.
It provides data integrity and replay protection for broadcast/
multicast robust management frames (not used yet) using AES-128
in CMAC mode.
