treewide: add support for "lto" in PKG_BUILD_FLAGS
This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".

Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."

Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed
that every buildsystem uses +$(MAKE) correctly.

dnsmasq: refuse to add empty DHCP range
Use ipcalc's return value to react to invalid range specifications.
By simply ignoring the range instead of aborting with an error code,
dnsmasq should still start when there's an error (best effort).
Aborting the config generation or working with invalid range specs leaves
dnsmasq crash-looping which is the right thing to do concerning that
particular interface but it also hinders DHCP service on other interfaces
and DNS on the router itself.

dnsmasq: nftset: serve from ipset config

Use existing ipset configs as source for nftsets to be compatible with
existing configs. As the OS can either have iptables XOR nftables
support, it's fine to provide both to dnsmasq. dnsmasq will silently
fail for the present one. Depending on the dnsmasq compile time options,
the ipsets or nftsets option will not be added to the dnsmasq config
file.

dnsmasq will try to add the IP addresses to all sets, regardless of the
IP version defined for the set. Adding an IPv6 to an IPv4 set and vice
versa will silently fail.

dnsmasq: obtain nftset ip family from nft

Unfortunately dnsmasq nft is noisy if an attempt to add a mismatched ip address
family to an nft set is made.

Heuristic to guess which ip family a nft set might belong by inferring
from the set name.

In order of preference:

If setname ends with standalone '4' or '6' use that, else
if setname has '4' or '6' delimited by '-' or '_' use that (eg
foo-4-bar) else
If setname begins with '4' or '6' standalone use that.

By standalone I mean not as part of a larger number eg. 24

If the above fails then use the existing nft set query mechanism and if
that fails, well you're stuffed!

With-thanks-to: Jo-Philipp Wich <jo@mein.io> who improved my regexp
knowledge.

dnsmasq: specify firewall table for nftset

Permit ipsets to specify an nftables table for the set.  New config
parameter is 'table'.  If not specified the default of 'fw4' is used.

config ipset
	list name 'BK_4,BK_6'
	option table 'dscpclassify'
	option table_family 'ip'
	option family '4'
	list domain 'ms-acdc.office.com'
	list domain 'windowsupdate.com'
	list domain 'update.microsoft.com'
	list domain 'graph.microsoft.com'
	list domain '1drv.ms'
	list domain '1drv.com'

The table family can also be specified, usually 'ip' or 'ip6' else the
default 'inet' capable of both ipv4 & ipv6 is used.

If the table family is not specified then finally a family option is
available to specify either '4' or '6' for ipv4 or ipv6 respectively.

This is all in addition to the existing heuristic that will look in the
nftset name for an ip family clue, or in total desperation, query the
value from the nftset itself.

ba5bd8e556 dnsmasq: distinct Ubus names for multiple instances
Currently, when using multiple dnsmasq instances they are all assigned
to the same Ubus instance name. This does not work, as only a single
instance can register with Ubus at a time. In the log, this leads to
`Cannot add object to UBus: Invalid argument` error messages.
Furthermore, upstream 3c93e8eb41952a9c91699386132d6fe83050e9be changes
behaviour so that instead of the log, dnsmasq exits at start instead.

With this patch, all dnsmasq instances are assigned unique names so that
they can register with Ubus concurrently. One of the enabled instances
is always assigned the previous default name "dnsmasq" to avoid breaking
backwards compatibility with other software relying on that default.
Previously, a random instance got assigned that name (while the others
produced error logs). Now, the first unnamed dnsmasq config section is
assigned the default name. If there are no unnamed dnsmasq sections the
first encountered named dnsmasq config section is assigned instead.

A similar issue exists for Dbus and was similarly addressed.

e87c0d934c dnsmasq: Update to version 2.83
This fixes the following security problems in dnsmasq:
* CVE-2020-25681:
  Dnsmasq versions before 2.83 is susceptible to a heap-based buffer
  overflow in sort_rrset() when DNSSEC is used. This can allow a remote
  attacker to write arbitrary data into target device's memory that can
  lead to memory corruption and other unexpected behaviors on the target
  device.
* CVE-2020-25682:
  Dnsmasq versions before 2.83 is susceptible to buffer overflow in
  extract_name() function due to missing length check, when DNSSEC is
  enabled. This can allow a remote attacker to cause memory corruption
  on the target device.
* CVE-2020-25683:
  Dnsmasq version before 2.83 is susceptible to a heap-based buffer
  overflow when DNSSEC is enabled. A remote attacker, who can create
  valid DNS replies, could use this flaw to cause an overflow in a heap-
  allocated memory. This flaw is caused by the lack of length checks in
  rtc1035.c:extract_name(), which could be abused to make the code
  execute memcpy() with a negative size in get_rdata() and cause a crash
  in Dnsmasq, resulting in a Denial of Service.
* CVE-2020-25684:
  A lack of proper address/port check implemented in Dnsmasq version <
  2.83 reply_query function makes forging replies easier to an off-path
  attacker.
* CVE-2020-25685:
  A lack of query resource name (RRNAME) checks implemented in Dnsmasq's
  versions before 2.83 reply_query function allows remote attackers to
  spoof DNS traffic that can lead to DNS cache poisoning.
* CVE-2020-25686:
  Multiple DNS query requests for the same resource name (RRNAME) by
  Dnsmasq versions before 2.83 allows for remote attackers to spoof DNS
  traffic, using a birthday attack (RFC 5452), that can lead to DNS
  cache poisoning.
* CVE-2020-25687:
  Dnsmasq versions before 2.83 is vulnerable to a heap-based buffer
  overflow with large memcpy in sort_rrset() when DNSSEC is enabled. A
  remote attacker, who can create valid DNS replies, could use this flaw
  to cause an overflow in a heap-allocated memory. This flaw is caused
  by the lack of length checks in rtc1035.c:extract_name(), which could
  be abused to make the code execute memcpy() with a negative size in
  sort_rrset() and cause a crash in dnsmasq, resulting in a Denial of
  Service.

acb336235c dnsmasq: 'ipset' config sections
Allow configuring ipsets with dedicated config sections:

    config ipset
        list name 'ss_rules_dst_forward'
        list name 'ss_rules6_dst_forward'
        list domain 't.me'
        list domain 'telegram.org'

instead of current, rather inconvenient syntax:

    config dnsmasq
        ...
        list ipset '/t.me/telegram.org/ss_rules_dst_forward,ss_rules6_dst_forward'

Current syntax will still continue to work though.

With this change, a LuCI GUI for DNS ipsets should be easy to implement.

/etc/hotplug.d/ntp/25-dnsmasqsec is being sourced by /sbin/hotplug-call
running as ntpd user. For that to work the file needs to be readable by
that user.

d7db32440f dnsmasq: include IPv6 local nameserver entry
For IPv6 native connections when using IPv6 DNS lookups, there is no
valid default resolver if ignoring WAN DHCP provided nameservers.

This uses a runtime check to determine if IPv6 is supported on the host.

2e746b4d29 busybox: make username consistent
ntpd in packages feed had already a user 'ntp' with UID 123 declared.
Rename the username of busybox-ntpd to be 'ntp' instead of 'ntpd' so
it doesn't clash.
