Previously, the option PrivateDevices=true disabled access to
/dev/rfkill, which lead to:
'iwctl adapter phy0 set-property Powered {off|on}'
to fail.
This patch explicitly allows access to /dev/rfkill
src/rtnlutil.c: In function ‘rtnl_route_add’:
./ell/util.h:248:2: error: ‘rtmmsg’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
Instead of using a flag ipv4_static, just store the value of the rtm
protocol directly inside netconfig object. This allows us to simplify
the logic quite significantly and avoid repeating the conditional
expression needlessly
The routes are installed as a result of a successful installation
of the IP addresses. The gateway is fetched with netconfig_ipv4_get_gateway
helper function according to the origin of the installed IP address.
The route priority offset can be set in main.conf. The default value
of 300 is used if the offset isn’t set.
The API allows to add connected and gateway routes to the main
routing table.
rtnl_route_ipv4_add_gateway() is equivalent to the following
example 'ip route' command:
ip route add default via 10.0.0.1 dev wlan0 proto dhcp src 10.0.0.2 metric 339
rtnl_route_ipv4_add_connected() is equivalent to the following
example 'ip route' command:
sudo ip route add 10.0.0.0/24 dev wlan0 proto dhcp src 10.0.0.2 scope link
The 'ip route' output from the above commands looks as follows:
rtnl_route_ipv4_add_connected():
10.0.0.0/24 dev wlan0 proto dhcp scope link src 10.0.0.2
rtnl_route_ipv4_add_gateway():
default via 10.0.0.1 dev wlan0 proto dhcp src 10.0.0.2 metric 339
The DNS addresses are installed as a result of a successful
installation of the IP addresses. The DNS lists are fetched
with netconfig_ipv4_get_dns helper function according to the
origin of the installed IP address.
iwd reconfigures the wireless interfaces with respective
connection events. Each supported network protocol is
reconfigured. The address for each protocol is
selected as static or dynamic based on availability.
netconfig_ipv4_get_ifaddr helper function allows to fetch IPv4
addresses from static or dynamic sources. The origin of the addresses
is noted in 'ipv4_is_static' flag.
For (Re)Association the HS20 indication element was passed exactly as
it was found in the scan results. The spec defines what bits can be
set and what cannot when this IE is used in (Re)Association. Instead
of assuming the AP's IE conforms to the spec, we now parse the IE and
re-build it for use with (Re)Association.
Since the full IE is no longer used, it was removed from scan_bss, and
replaced with a bit for HS20 support (hs20_capable). This member is
now used the same as hs20_ie was.
The version parsed during scan results is now used when building the
(Re)Association IE.
The parser fully parses the IE and returns the version, Domain ID,
and PPS MO ID. This is meant to be used with an IE in scan results.
The builder only takes the version number, and assumes DGAF disabled,
and no Domain ID or PPS MO ID.
Previously, iwd used to throw net.connman.iwd.Busy when connection
attempt was made while connected. The new behavior allows iwd to
seamlessly disconnect from the connected network and attempt a new
connection.
Since NAI realms, Roaming Consortium and HESSID are defined in 802.11,
they are not a guarentee that the network is Hotspot 2.0. The indication
element in addition to these IE's gives a better idea of Hotspot 2.0
support. Now, when a BSS is added this is_hs20 boolean will get set to
true if the HS20 IE was found in the BSS.
Now, if is_hs20 is set AND one of NAI realms, roaming consortium, or
HESSID is set we know this is a hotspot 2.0 network.
It is possible for a zero-length anti-clogging token payload to cause
IWD to abort. If the length passed into sae_process_anti_clogging was
1, l_memdup would be called with a size of -1. This will cause malloc
to abort.
Fix this by checking for a minimum packet length and dropping the
packet if the length is too small.
The HS20 indication element should always be included during
(Re)Association per the spec. This removes the need for a
dedicated boolean, and now the hs20_ie can be used instead.
The hotspot spec specifically mentions the roaming consortium OI be
3 or 5 bytes long. This requirement also prevents potential buffer
overflows if the user were to configure a long roaming consortium OI.
If the scan was triggered and later aborted, make sure to reset the
triggered value when the CMD_NEW_SCAN_RESULTS event comes in.

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.
