are returned for a hostname as they're seperated by newline by

Now that the uhttpd init script can generate certificates using openssl as
well, update the section name and related comment to be more generic.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
Support the usage of the OpenSSL command-line tool for generating
the SSL certificate for uhttpd. Traditionally 'px5g' based on
PolarSSL (or mbedTLS in LEDE), has been used for the creation.
uhttpd init script is enhanced by adding detection of an installed
openssl command-line binary (provided by 'openssl-util' package),
and if found, the tool is used for certificate generation.
Note: After this patch the script prefers to use the OpenSSL tool
if both it and px5g are installed.
This enables creating a truly OpenSSL-only version of LuCI
without dependency to PolarSSL/mbedTLS based px5g.

Within the Lua binding, use the same logic as the command line interface for
reporting the used WPA ciphers. Instead of printing the intersection of
pairwise and group ciphers, report both group and pairwise ciphers.
This fixes a case where a connection which uses CCMP for pairwise and TKIP
as groupwise cipher is getting reported as using the NONE cipher.

Configurations without shadow passwords have been broken since the removal
of telnet: as the default entry in /etc/passwd is not empty (but rather
unset), there will be no way to log onto such a system by default. As
disabling shadow passwords is not useful anyways, remove this configuration
option.
The config symbol is kept (for a while), as packages from feeds depend on
it.

Match sections allow to set a tag specified by the option networkid if the client
sends an option and optionally the option value specified by the match option.
The force option will convert the dhcp-option to force-dhcp-option if set to 1 in
the dnsmasq config if options are specified in the dhcp_option option.

Don't expose dnsmasq version & other data to clients via the *.bind
pseudo domain. This uses a new 'NO_ID' compile time option which has been
discussed and submitted upstream.
This is an alternate to replacing version with 'unknown' which affects
the version reported to syslog and 'dnsmasq --version'
Run time tested with & without NO_ID on Archer C7 v2

Regression introduced by 3481d0d dnsmasq: run as dedicated UID/GID
dnsmasq is unable to remove its own pidfile as /var/run/dnsmasq is owned
by root and now dnsmasq runs as dnsmasq:dnsmasq. Change directory
ownership to match.
dnsmasq initially starts as root, creates the pidfile, then drops to
requested non-root user. Until this fix dnsmasq had insufficient
privilege to remove its own pidfile.

PPP daemon can be put into persist mode meaning the
daemon will not exit after a connection gets terminated
but will instead try to reopen the connection.
The re-initiation after the link has been terminated
can be controlled via holdoff; this is helpfull in
scenarios where a BRAS is in denial of service mode
due to link setup requests after a BRAS has gone down
Following uci parameters have been added :
persist (boolean) : Puts the ppp daemon in persist mode
maxfail (integer) : Number of consecutive fail attempts which
puts the PPP daemon in exit mode
holdoff (interget) : Specifies how many seconds to wait
before re-initiating link setup after it has been terminated

* 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
