Tobias WaldekranzandJoachim Wiberg f660f6e9c7 qemu: Homogenize network setup
- Always respect the requested model to emulate. Before this change, a
  device configured to run in TAP mode would ignore a user's requested
  model and always emulate a e1000.

  This worked on x86_64 where that driver is part of the kernel, but
  that is not true for aarch64.

- Always supply a mactab. It was very confusing that the interface
  names would change, in Infix, depending on the selected networking
  mode.

- Remove old decoy variables that were assigned but never used
  anywhere.

- Separately setup the host and target side of a nic (i.e. use a
  -netdev/-device pair instead of the -nic shortcut). This lets us
  share the host side setup across all modes.

Joachim WibergandTobias Waldekranz 17ff8677ee board/common: replace default editor, nano -> mg
This reverts an earlier change where nano was made the default editor in
a misguided attemt by yours truly to accomodate beginner users.

With the recent improvements of the CLI and the fact that the NETCONF
support has matured greatly, the need for a user-friendly editor have
diminished drastically.  Editing system files is now limited to devs
and the core team prefers Mg over nano and vi.

The upstream help system has improved greatly.  We can now rely more on
it for generating the man-page like help texts for leaf nodes.  There
is also a new srp_prompt symbol that overrides the default klish one,
srp_prompt adds a '%x' format specifier for an inline path instead of
the default [edit foo bar] JunOS style two-liner.

Joachim WibergandTobias Waldekranz b95a82207d package/klish: switch to kkit branch @kernelkit, new features
This commit switches the klish package to use the kkit branch instead of
keeping a lot of patches from the v3.0.0 release.

Most of the changes made are for dragging tinyrl into the 21st century.
It now supports most of the basic features one have come to expect from
a readline replacement: line navigation, deleting words, erasing entire
line, kill and yank of lines/words and last argument on previous line.

The history has also gotten a bit of a stern talking to.  It no longer
deletes lines matching existing old ones from the history, instead it
just checks if the previous command is repeated.

Joachim WibergandTobias Waldekranz d4b23eac75 klish: klish-plugin-sysrepo: klinfix: bump for new srp_prompt@sysrepo
This commit changes the JunOS look of the CLI to something more akin to
a standard shell.  To achieve this a %w format specifier to display the
path components is added to both klish and klish-plugin-sysrepo.

Before:
	admin@infix-12-34-56:exec> configure
	[edit]
	admin@infix-12-34-56:configure> ediit interfaces interface eth0
	[edit interfaces interface eth0]
	admin@infix-12-34-56:configure> leave
	admin@infix-12-34-56:exec>

After:
	admin@infix-12-34-56:/> configure
	admin@infix-12-34-56:/config/> edit interfaces interface eth0
	admin@infix-12-34-56:/config/interfaces/interface/eth0/> leave
	admin@infix-12-34-56:/> leave

However, due to unforseen problems with the naming of VIEWs in klish,
the admin-exec level "path" is hard-coded to "/" for now.

Future imporovement: fold in calling prompt@klish from srp_prompt, and
figure out why the "main" VIEW cannot be changed to "exec" without klish
just bailing out starting up.

Turns out one of the reasons some keys did not work as they should in

default TERM variable being set to 'linux'.  Changing to 'xterm' fixes
this issue, works with both console and ssh login, and from testing do
not seem to have any adverse effects on existing functionality.

Joachim WibergandTobias Waldekranz 63aa130e9c klinfix: restore Ctrl-C to abort current line, use Ctrl-D instead
While spending the past couple of weeks actually trying to use the CLI,
I realized that it was very confusing to have a different behavior for
Ctrl-C than I was used to from regular shells (including the old clish
from $OLDJOB).

This change drops the Ctrl-C binding, restoring break/abort behavior,
and lets Ctrl-D be abort/exit.  Pressing Ctrl-D in a sub-context in
configure calls exit, when in the top-most configure context we now
do an abort and return to admin-exec.

To apply the changes the user still has to type 'commit' or 'leave',
or tap Ctrl-Z as in the Cisco CLI.

Joachim WibergandTobias Waldekranz 24d9a6dfc6 klinfix: add new commands password [generate | encrypt]
An excellent example of how to define commands with optional subcommands
and optional parameters:

  password encrypt [type <md5 | sha256 | sha512>] [salt STRING] [PASSWORD]

The tricks here are two:

  1. mode="switch" in the top-level password command
  2. min="0" in the encrypt subcommands

The first turns the COMMAND element into a SWITCH element (with command
matching), and the second makes a COMMAND optional.  If an optional
command is input by the user, then the enclosed PARAM is mandatory.

Please note, due to limitations in the mkpasswd¹ utility, spaces are not
supported in PASSWORD, i.e., when read from CLI prompt.  However, spaces
are allowed when using the interactive prompt, i.e., when omitting the
PASSWORD from the CLI prompt.

¹) mkpasswd does not look for any leading ' or " in the password arg.

This commit enables a basic sanity check of usernames in BusyBox that by
default is disabled (!).  The rules enabled by this are:

 - the user or group name should consist only of letters, digits,
   underscores, periods, and dashes¹, and not start with a dash (as
   defined by IEEE Std 1003.1-2001), or periods²

 - for compatibility with Samba machine accounts, $ is supported at the
   end of names

 - max length of user or group name is 256 chars

Changes in this commit also includes a sync with latest BusyBox 1.36,
which adds: tree, tsort, SHA hw acceleration, and a separate script
for udhcpc6.

_____
¹) The documentation actually mentions "and at-signs" as well, but that
   has been explicitly removed from the source code.
²) The documentation does not mention that leading periods are not
   allowed, though this is also explicitly mentioned in the source code.

Joachim WibergandTobias Waldekranz 528ea61302 confd: set up compat authorized_keys symlink for netopeer2-server
Apparently netopeer2-server expects public keys for users to be in the
canonical place (~/.ssh/authorized_keys).  Infix use a custom location
in /var/run, maintained by the ietf-system plugin, which OpenSSH knows
but netopeer2-server doesn't.

It seems to be possible to add some sort of "pattern" to netopeer2 to
indicate where to look for public keys.  This is added when building it
but Buildroot does not expose this as a setting.  So for now, this seem
to be the least intrusive way of handling it.  The owner is root, so a
malicious user cannot change the link or contents without some other
form of privilege escalation first.
