beacon intervals of all VIFs of the same radio to match. This often broke

some configurations (observed on ath9k).
Instead of relying on driver or hostapd defaults, change the scripts to
always explicitly set the beacon interval, defaulting to 100. This also
applies the beacon interval to 11s interfaces, which had been forgotten
before. VIF-specific beacon_int setting is removed from hostapd.sh.

When sta is configured, hostapd receives 'stop' and 'update' command from
wpa_supplicant. In the update command, hostapd gets sta parameters with
which it configures ap.
Problem is, with the default wireless configuration:
mode:11g freq:2.4GHz channel:1
If sta is connected to 5GHz network, then ap does not work. Ideally with
340-reload_freq_change.patch hostapd should reload the frequency changes
and start ap in 5GHz, but ap becomes invisible in the network.
This issue can be reproduced with following /etc/config/wireless:
config wifi-device radio0
option type mac80211
option channel 1
option hwmode 11g
option path 'virtual/uccp420/uccwlan'
option htmode 'none'
config wifi-iface 'ap'
option device 'radio0'
option encryption 'none'
option mode 'ap'
option network 'ap'
option ssid 'MyTestNet'
option encryption none
config wifi-iface 'sta'
option device radio0
option network sta
option mode sta
option ssid TestNet-5G
option encryption psk2
option key 12345

RFC 6761 defines a number of top level domains should not be forwarded
to the Internet's domain servers since they are not responsible for
those domains.
This change adds a list of domains that will be blocked when 'boguspriv'
is used and augments that which is already blocked by dnsmasq's notion
of 'local service' using '--bogus-priv' i.e. RFC 1918 private addresses
and IPv6 prefixes as defined in RFC 6303.
To make this configurable rather than hard coded in dnsmasq's init
script, a new file /usr/share/dnsmasq/rfc6761.conf is conditionally
included.
The default file matches the RFC 6761 recommendation along with a few
other top level domains that should not be forwarded to the Internet.

dnsmasq has sufficient services to meet the needs of DHCP
and RA with IP6 for single router router users. This is
the most common use for consumer routers. Its reenforced
as most ISP tend to only DHCP-PD /64. dnsmasq has year
over year demonstrated great flexibility in its option
set, and support for off-standard DHCP clients.
odhcpd has enhanced capabilities focused on IP6 such
as DHCP/RA relay and NDP proxy. However, it is not as
flexible in its option set. odhcpd is not as forgiving
with off-standard DHCP clients. Some points may represent
a long term TODO list, but it is the state currently.
These changes make any such combination possible. Already
odhcpd can be set as the main dhcp server. Now odhcpd
can be removed or disabled and dnsmasq will take over
if DHCPv6 compiled in. The existing DHCPv6 and RA UCI
are translated into dnsmasq.conf. The changes focus on
'--dhcp-range', '--dhcp-host', and '--dhcp-options'.
DHCP host ID is least 16 bits [::1000-::FFFF], but
leaves low range for typical infrastructure assignments.
dnsmasq accepts DHCPv6 options in the tranditional
'--dhcp-option' put they must be prefixed 'option6:'.
dnsmasq will also discover SLAAC DNS entries from DHCPv4
clients MAC, and confirm with a ping at least renew.
Long term TODO include improving use of dnsmasq relay
options for DHCPv4 and DHCPv6 in parallel. It would also
be possible to preconfigure DHCP-PD in host-with-options
records for fixed infrastructure.

do not occur, then address changes are not tracked. The script doesn't
apply all the addresses at an interface. This may make logs obscure.
The script only puts the bare host name (maybe not FQDN) in host file,
but if '--exapandhosts' is enabled, then /etc/hosts entries will be
suffixed, and "127.0.0.1 localhost" becomes "localhost.lan".
dnsmasq provides an option to perform this function, but it is rather
greedy. '--interface-name=<name>,<iface>' will assign the name to all
IP on the specified interface (except link local). This is a useful
feature, but some setups depend on the original restrictive behavior.
'option add_local_fqdn' is added to enhance the feature set, but
if not entered or empty string, then it will default to original
option and behavior. This new option has a few settings. At each
increased setting the most detailed name becomes the PTR record:
0 - same as add_local_hostname 0 or disabled
1 - same as add_local_hostname 1
2 - assigns the bare host name to all IP w/ --dnsmasq-interface
3 - assigns the FQDN and host to all IP w/ --dnsmasq-interface
4 - assigns <iface>.<host>.<domain> and above w/ --dnsmasq-nterface
'option add_wan_fqdn' is added to run the same procedure on
inferred WAN intefaces. If an interface has 'config dhcp' and
'option ignore 1' set, then it is considered WAN. The original
option would only run on DHCP serving interfaces.

This will allow starting hostapd with the new -s parameter and finally
read all (error) messages from the syslog.

It wasn't possible to read hostapd wpa_printf messages unless running
hostapd manually. It was because hostapd was printing them using vprintf
and not directly to the syslog.
We were trying to workaround this problem by redirecting STDIN_FILENO
and STDOUT_FILENO but it was working only for the initialization phase.
As soon as hostapd did os_daemonize our solution stopped working.
Please note despite the subject this change doesn't affect debug level
messages only but just everything printed by hostapd with wpa_printf
including MSG_ERROR-s. This makes it even more important as reading
error messages can be quite useful for debugging.

Updates to openvpn.init were included in early OpenVPN 2.4 patch
series, but got lost along the way and were never merged.
