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.

[Jo-Philipp Wich: emit proper IPv6 hostid format in dhcp-host directive]
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
ref commit 612e2276b4
ref commit ec63e3bf13
'option add_local_hostname' scripted implementation statically assigns
this host in auto generated host file at init. If IFUP or other signals
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.

It wasn't possible to read hostapd wpa_printf messages unless running

As soon as hostapd did os_daemonize our solution stopped working.
Please note despite the subject this change doesn't affect debug level

including MSG_ERROR-s. This makes it even more important as reading

This causes problem when a FQDN is configured in /etc/config/system. The
domain name will appear twice in reverse DNS.
Next to that, there seems to be a bug in dnsmasq. From the manual page:
--interface-name=<name>,<interface>[/4|/6]
Return a DNS record associating the name with the primary address
on the given interface. This flag specifies an A or AAAA record for the
given name in the same way as an /etc/hosts line, except that the address
is not constant, but taken from the given interface. The interface may be
followed by "/4" or "/6" to specify that only IPv4 or IPv6 addresses
of the interface should be used. If the interface is down, not configured
or non-existent, an empty record is returned. The matching PTR record is
also created, mapping the interface address to the name. More than one name
may be associated with an interface address by repeating the flag; in that
case the first instance is used for the reverse address-to-name mapping.
It does not just create an A/AAAA record for the primary address, it creates
one for all addresses. And what is worse, it seems to actually resolve to the
non-primary address first. This is quite annoying when you use floating IP
addresses (e.g. VRRP), because when the floating IP is on the other device,
SSH failes due to incorrect entry in the known hosts file.
I know that this is not a common setup, but it would be nice if there was an
option to restore the previous behaviour, rather than just forcing this new
feature on everybody.

'add_local_hostname' previous implementation may drop some addresses.
Soft addition of IP6 addresses may not cause a reload or restart event.
dnsmasq '--interface-name' robustly applies DNS to all addresses per
interface (except fe80::/10).
Change UCI 'add_local_hostname' to expand during each interface assignement
during add_dhcp().
Assign '<iface>.<host>.<domain>' as true name (reflexive A, AAAA, and PTR).
Assign '<host>.<domain>' and '<host>' as convinience aliases (no PTR, not
technically CNAME).
This is accomplished with the '--interface-name' order, first is PTR.
We could also assign each <ip4/6>.<iface>.<host>.<domain> to the respective
dual stack on the interface.
That seemed excessive so it was skipped (/4 or /6 suffix to the interface).
Add UCI 'add_wan_hostname' similar to 'add_local_hostname' function for
external WAN.
WAN IP4 are less often named by the ISP and rarely WAN IP6 due to complexity.
For logs, LuCI connection graph, and other uses assigning a WAN name is desired.
'add_local_hostname' only applies with DHCP and 'add_wam_hostname' only applies
without DHCP. Common residential users will want to set both options TRUE.
Businesses will probably have global DNS, static IP, and 'add_wan_hostname' FALSE.

Certificates created by the OpenSSL one-liner fall into that category.
Avoid identical certificate subjects by including a new 'O=' item

* Only parse interfaces that are up during init_config (as the
script depends on this to determine the proper IP/subnet range)
* Add reload interface triggers for samba-designated interfaces
* Force full service restart upon config change to ensure Samba
binds to new interfaces (sending HUP signal doesn't work)
* Rename "interface" variable to "samba_iface" and move into
global scope
Needed to fix Samba connectivity for clients connecting from a
different LAN subnet (e.g. pseudobridge configurations) due to the
'bind interfaces only' setting.

- Security: Message printout was vulnerable to format string injection.
If specific usernames including "%" symbols can be created on a system
(validated by getpwnam()) then an attacker could run arbitrary code as root
when connecting to Dropbear server.
A dbclient user who can control username or host arguments could potentially
run arbitrary code as the dbclient user. This could be a problem if scripts
or webpages pass untrusted input to the dbclient program.
- Security: dropbearconvert import of OpenSSH keys could run arbitrary code as
the local dropbearconvert user when parsing malicious key files
- Security: dbclient could run arbitrary code as the local dbclient user if
particular -m or -c arguments are provided. This could be an issue where
dbclient is used in scripts.
- Security: dbclient or dropbear server could expose process memory to the
running user if compiled with DEBUG_TRACE and running with -v
The security issues were reported by an anonymous researcher working with
Beyond Security's SecuriTeam Secure Disclosure www.beyondsecurity.com/ssd.html

RADIUS accounting can be used even when RADIUS authentication is not
used. Move the accounting configuration outside of the EAP-exclusive
sections.

multiple invocation of dnsmasq script (e.g. by procd and hotplugd)
might cause procd to restart dnsmasq with an incomplete config file.
Config file generation might take quite a long time on larger configs
due ubus calls for each listening interface...

Removed socket options = TCP_NODELAY IPTOS_LOWDELAY
TCP_NODELAY (disables Nagle algorithm) is default since samba2.
IPTOS_LOWDELAY sets DSCP 0x10 coding (CS2)
The alternate IPTOS_THROUGHPUT sets DSCP 0x08 coding (CS1)
CS1 is a scavenger class, whilst CS2 is more OAM/interactive
(SNMP,SSH,syslog)
Using CS2 is definitely an abuse of DSCP classification, CS1 less so
however even if the ISP takes note of DSCP codings having a default that
sets traffic to CS2 is wrong. Better to use the default Best Effort
class.

Move logging command line option to uci:
option verbose [0]/1/2 - mono-syllabic/verbose/noisy
Previously handled as 'OPTIONS' in .init script however variable
was ignored so never worked.

Removed some options which are default anyway and added bind interfaces
only which causes the interfaces line to actually have an effect. Can be
verified with netstat.
