- Security: Fix double-free in server TCP listener cleanup A double-free
in the server could be triggered by an authenticated user if dropbear is
running with -a (Allow connections to forwarded ports from any host)
This could potentially allow arbitrary code execution as root by an
authenticated user.  Affects versions 2013.56 to 2016.74. Thanks to Mark
Shepard for reporting the crash.
CVE-2017-9078 https://secure.ucc.asn.au/hg/dropbear/rev/c8114a48837c

- Security: Fix information disclosure with ~/.ssh/authorized_keys
symlink.  Dropbear parsed authorized_keys as root, even if it were a
symlink.  The fix is to switch to user permissions when opening
authorized_keys

A user could symlink their ~/.ssh/authorized_keys to a root-owned file
they couldn't normally read. If they managed to get that file to contain
valid authorized_keys with command= options it might be possible to read
other contents of that file.
This information disclosure is to an already authenticated user.
Thanks to Jann Horn of Google Project Zero for reporting this.

One of the latest mac80211 updates added sanity checks, requiring the
beacon intervals of all VIFs of the same radio to match. This often broke
AP+11s setups, as these modes use different default intervals, at least in
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.

Fixes FS#619.

in /etc/config/dhcp.

With the interface_name option users can define a DNS name for each dhcp section
that will be resolved by dnsmasq with the underlaying interface address.

For example:
config dhcp 'lan'

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

This change updates current_mode structure based on configured hw_mode
received from wpa_supplicant. Also prepare rates table after frequency
selection.

This change protects the openvpn instances to be marked as "in a crash
loop" and thereby the connection retries will run infinitely.

When the remote site of an openvpn connection goes down for some time
(network failure etc.) the openvpn instance in an openwrt/lede device
should not stop retrying to establish the connection.

With the current limit of 5 retries, there is a user interaction
required, which isn't really what you want when the device should
simply do everything to keep the vpn connection up.

Previous updates made umdns work as expected on startup but there were
still many bugs. They were mostly related to runtime - cache management
and requests + responses. E.g. umdns was never able to send question on
DNS record expire. It was also ignoring all incoming unicast questions.

Since these issues are quite serious it makes sense to backport this
update to the stable branch.

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.
