Simply prints the ANQP ID (human readable) and the length. Once
the ANQP dependency on netdev is removed the full ANQP parser
can be used, but for now its done manually. Once this is done it
will be much easier to print the actual ANQP ID data.
In the same fashion as the WSC WFA OUI, ie.[ch] will now expose the
other vendor OUIs to avoid duplication across multiple files in IWD
as well as used in iwmon.
P2P probe requests are to be sent at min 6.0 Mb/s using OFDM,
specifically the 802.11b rates are prohibited (section 2.4.1 in Wi-Fi
P2p Technical Spec v1.7), some of which use CCK modulation. This is
already the default for 5G but for 2.4G the drivers generally do this
if we set the NL80211_ATTR_TX_NO_CCK_RATE flags with
NL80211_CMD_TRIGGER_SCAN.
The length check was incorrectly assuming that PPS MO ID or
ANQP Domain ID would be present in the IE. Both these are optional
and without then the minimum length is 5 bytes, not 7.
Per the hotspot 2.0 spec, if a matching roaming consortium OI is
found it should be added to the (Re)Association request. vendor_ies
can now be provided to netdev_connect, which get appended to the IE
attribute.
This API will attempt to find a matching roaming consortium OI
if present in the config file. A single matching OI is returned
or NULL if one was not found.
Hotspot 2.0 network providers allow 'roaming' between a users home
network and other providers networks, assuming they are part of the
same roaming consortium. The roaming consortium is advertised as an
IE in beacon/probe frames.
In terms of the hotspot config files this is similar to HESSID, where
if the AP advertises the roaming consortium IE, and the config file
matches we do not need to do ANQP in order to connect.
This is duplicated when the first scan_bss is added to a network
object that contains the IE. Any future BSS's added will not re-add
the IE. Its assumed that all BSS's under a network will contain the
same roaming consortium OIs.
Parses up to 3 (the max) roaming consortium OIs out of the roaming
consortium IE. If more OIs are available via ANQP the 'num_anqp_out'
value will be set to indicate how many more OIs are available.
Builds according to the hotspot 2.0 spec using the vendor specific
IE.
Declare structures to hold the parsed contents of the P2P IEs and WSC
IEs in P2P-related frames and add functions to free memory used by
those structures.
Define structs and types for most P2P attributes and p2p_parse_attrs
similar to wsc_parse_attrs -- a generic parser for attributes in a P2P
IE payload. This parser may write into the provided buffer even on
error but it's private to p2putil.c. The local callers will take care
of keeping the user-provided buffers untouched on error.
