CVE-2017-15107
An interesting problem has turned up in DNSSEC validation. It turns out
that NSEC records expanded from wildcards are allowed, so a domain can
include an NSEC record for *.example.org and an actual query reply could
expand that to anything in example.org and still have it signed by the
signature for the wildcard. So, for example
!.example.org NSEC zz.example.org
is fine.
The problem is that most implementers (your author included, but also
the Google public DNS people, powerdns and Unbound) then took that
record to prove the nothing exists between !.example.org and
zz.example.org, whereas in fact it only provides that proof between
*.example.org and zz.example.org.
This gives an attacker a way to prove that anything between
!.example.org and *.example.org doesn't exists, when it may well do so.

Add sendopts config support allowing to add options in sent DHCPv6 packets.
Options can be configured as follows :

Dnsmasq used SIGHUP to do too many things: 1) set dnssec time validation
enabled, 2) bump SOA zone serial, 3) clear dns cache, 4) reload hosts
files, 5) reload resolvers/servers files.
Many subsystems within LEDE can send SIGHUP to dnsmasq: 1) ntpd hotplug
(to indicate time is valid for dnssec) 2) odhcpd (to indicate a
new/removed host - typically DHCPv6 leases) 3) procd on interface state
changes 4) procd on system config state changes, 5) service reload.
If dnssec time validation is enabled before the system clock has been
set to a sensible time, name resolution will fail. Because name
resolution fails, ntpd is unable to resolve time server names to
addresses, so is unable to set time. Classic chicken/egg.
Since commits 23bba9cb33 (service reload) &
4f02285d8b (system config) make it more
likely a SIGHUP will be sent for events other than 'ntpd has set time'
it is more likely that an errant 'name resolution is failing for
everything' situation will be encountered.
Fortunately the upstream dnsmasq people agree and have moved 'check
dnssec timestamp enable' from SIGHUP handler to SIGINT.
Backport the upstream patch to use SIGINT.
ntpd hotplug script updated to use SIGINT.

Some newer LTE modems, like the MC7455 or EC25-E do not support
"802.3" mode, and will stay in "raw-ip" regardless of the mode being
set.
In this case, the driver must be informed that it should handle all
packets in raw mode. [1]
This commit fixes connectivity issues for these devices.

In order to properly support 802.11w, hostapd needs to advertise a group
management cipher when negotiating associations.
Introduce a new per-wifi-iface option "ieee80211w_mgmt_cipher" which
defaults to the standard AES-128-CMAC cipher and always emit a
"group_mgmt_cipher" setting in native hostapd config when 802.11w is

The git hash was changed for multiple layerscape packages without
changing the version number. The LEDE build system will not download the
packages again if the old version is already there and so some people
and the build bots are using wrong version of some packages. Use
PKG_SOURCE_DATE instead of PKG_VERSION to generate packages with the
date and the first charterers of the git hash. This will change the file
name and make the build system download them again, also if in future
the git hash is changed the file name will change and trigger a new
download.
This should fix a problem spotted by build bot.

There has been recent significant activity with the cake qdisc of late
Some of that effort is related to upstreaming to kernel & iproute2
mainline but we're not quite there yet. This commit teaches tc how to
activate and interprete the latest cake operating modes, namely:
ingress mode: Instead of only counting packets that make it past the
shaper, include packets we've decided to drop as well, since they did
arrive with us on the link and took link capacity.
This mode is more suitable for shaping the ingress of a link
(e.g. from ISP) rather than the more normal egress.
ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in
highly assymetric links (downstream v upstream capacity) where the
majority of upstream link capacity is occupied with ACKS for downstream
traffic.

Different invocations of the dnsmasq init script (e.g. at startup by procd)
will rewrite the dhcp host file which might result into dnsmasq reading an
empty dhcp host file as it is being rewritten by the dnsmasq init script.
Let the dnsmasq init script first write to a temp dhcp host file so it does
not overwrite the contents of the existing dhcp host file.

wpa_disable_eapol_key_retries can't prevent attacks against the
Tunneled Direct-Link Setup (TDLS) handshake. Jouni Malinen suggested
that the existing hostapd option tdls_prohibit can be used to further
complicate this possibility at the AP side. tdls_prohibit=1 makes
hostapd advertise that use of TDLS is not allowed in the BSS.
Note: If an attacker manages to lure both TDLS peers into a fake
AP, hiding the tdls_prohibit advertisement from them, it might be
possible to bypass this protection.
Make this option configurable via UCI, but disabled by default.
