The function _osmo_fsm_inst_term() terminates all child FSMs befor
it calls fi->fsm_cleanup(). This prevents the cleanup callback to
perform last actions on the child FSMs (e.g.
osmo_fsm_inst_unlink_parent()).
- Since moving the cleanup callack to the beginning of the function
would alter the termination behavior and possibly cause malfunction
in already existing implementation that use OSMO fsm, a new
optional callback that is called immediately at the beginning of
the terminatopn process is added.

According to the GSM 04.80 (version 5.0.0) specification Annex A

6.1.2.3 "USSD packing of 7 bit characters", in 160 octets, it's
possible to pack (160 * 8) / 7 = 182.8, that is 182 characters.

If a control command fails to parse, we so far discard specific error messages
and instead send just "Command parser error".
In ctrl_cmd_parse() we actually compose detailed error replies, but in the end
simply talloc_free() them and return NULL.
A first step to report these errors to the ctrl command issuer is to not return
NULL and instead return the cmd with type = CTRL_TYPE_ERROR. Add
ctrl_cmd_parse2() to return such instead of NULL.
To stay API compatible, provide ctrl_cmd_parse2() to return a cmd on errors.
ctrl_cmd_parse() retains identical behavior but becomes just a simple wrapper
around ctrl_cmd_parse2() which discards the cmd on error.
No need really to deprecate ctrl_cmd_parse() yet; especially as long as

To send a Ciphering Mode Command, we may need to derive a Kc from UMTS AKA

For SRES, it requires an OPC, which may need to be derived from OP first. All
we need is a Kc, so we could feed a zero OPC ... but to simplify the function
call for cases where just a Kc is required, separate the c3 function out from
gsm_milenage(), as osmo_auth_c3(). Obviously call osmo_auth_c3() from
gsm_milenage() (meaning that osmo-hlr's 55.205 derived auc tests still cover

For example encode_auth_info() from gsup.c calls
msgb_tlv_put(msg, iei, 0, NULL)
to put a tag and len with content data following later.
However, this would cause a memcpy() from a NULL pointer, in tlv_put(). Allow
passing NULL and len = 0 for cases like the above:
If val is NULL, use memset(0) instead of memcpy().
If len is zero, do not copy nor memset anything.

Old bitvec_set_uint() uses "unsigned int" as input parameter which
length is not guaranteed. It does not allow to specify which bit_value
to set and does not check for incorrect length. Overall this makes it
harder to re-use and more error-prone.
Let's replace it with extended implementation which uses fixed type
length parameters and extra checks. The additional parameter allows
caller to explicitly indicate the need to use L/H instead of 0/1 for bit
vector elements. It's necessary to properly encode some of the messages
from 3GPP TS 44.018, for example §10.5.2.16 IA Rest Octets.
The old function is left for backward compatibility as a tiny wrapper
around new function and will be deprecated in follow-up patches.

Add ctrl_interface_setup_dynip2() to add a node_count parameter, which can be
used to define more ctrl nodes without having to merge a patch to libosmocore.
In consequence, also add ctrl_handle_alloc2(), since
ctrl_interface_setup_dynip() uses ctrl_handle_alloc() to allocate the node
slots, and add node_count param to static ctrl_init().
Passing zero as node_count indicates to use the default of _LAST_CTRL_NODE as
before, i.e. to not define more ctrl nodes. Assert that we never allocate less
than _LAST_CTRL_NODE slots.
The current ctrl_interface_setup_dynip() and ctrl_handle_alloc() become simple

In many callers of the VTY API, we are lacking the vty_install_default() step
at certain node levels. This creates nodes that lack the 'exit' command, and
hence the only way to exit such a node is to restart the telnet session.
Historically, the VTY looked for missing commands on the immediate parent node,
and hence possibly found the parent's 'exit' command when the local node was
missing it. That is why we so far did not notice the missing default commands.
Furthermore, some callers call install_default() instead of
vty_install_default(). Only vty_install_default() also includes the 'exit' and
'end' commands. There is no reason why there are two sets of default commands.
To end this confusion, to catch all missing 'exit' commands and to prevent this
from re-appearing in the future, simply *always* install all default commands
implicitly when calling install_node().
In cmd_init(), there are some top-level nodes that apparently do not want the
default commands installed. Keep those the way they are, by changing the
invocation to new install_node_bare() ({VIEW,AUTH,AUTH_ENABLE}_NODE).
Make both install_default() and vty_install_default() no-ops so that users of
the API may still call them without harm. Do not yet deprecate yet, which
follows in Icf5d83f641e838cebcccc635a043e94ba352abff.

This change introduces a new command, which could be used to
inspect the application's talloc context directly from VTY.
To enable this feature, an application need to provide it's
context via the 'vty_app_info' struct, and register the VTY
command by calling the osmo_talloc_vty_add_cmds().
The new command is a sub-command of 'show':
show talloc-context <context> <depth> [filter]
Currently the following contexts may be inspected:
- application - a context provided by an application;
- null - all contexts, if NULL-context tracking is enabled.
A report depth is defined by the next parameter, and could be:
- full - full tree report, as the talloc_report_full() does;
- brief - brief tree report, as the talloc_report() does;
- DEPTH - user defined maximal report depth.
Also, there are two optional report filters:
- regexp - print only contexts, matching a regular expression;
- tree - print a specific context, pointed by specified address.
The command output is formatted the same way as in case of calling
the talloc_report() or talloc_report_full().

The 'show online-help' produces XML output with <node id="..."> ids. We
reference those from the osmo-gsm-manuals.
Instead of numeric IDs coming from internal code, rather use a human-readable
node ID -- referencing id='config-msc' is much easier than referencing id='23'.
Add a char name[] to struct cmd_node, to hold this name. This may be provided
upon struct definition.
Since callers of the VTY API so far don't have a name yet, we would need to add
names everywhere to get meaningful node IDs. There is a way to get node ID
names without touching dependent code:
My first idea was to find out which command entered the node, i.e. command
'msc' enters the MSC_NODE. But it is impossible to derive which command entered
which node from data structs, it's hidden in the vty command definition.
But in fact all (TM) known API callers indeed provide a prompt string that
contains a logical and human readable string name. Thus, if the name is unset
in the struct, parse the prompt string and strip all "weird" characters to
obtain a node name from that. We can still set names later on, but for now will
have meaningful node IDs (e.g. 'config-msc' from '%s(config-msc)# ') without
touching any dependent code.
When VTY nodes get identical node names, which is quite possible, the XML
export de-dups these by appending _2, _3,... suffixes. The first occurence is
called e.g. 'name', the second 'name_2', then 'name_3', and so forth.
If a node has no name (even after parsing the prompt), it will be named merely
by the suffix. The first empty node will become id='_1', then '_2', '_3', and
so forth. This happens for nodes like VIEW_NODE or AUTH_NODE.
If this is merged, we need to adjust the references in osmo-gsm-manuals.git.
This can happen in our own time though, because we manually create the vty
reference xml and copy it to the osmo-gsm-manuals.git and then update the
references from the vty_additions.xml. This anyway has to happen because
currently the references tend to be hopelessly out of sync anyway, placing
comments at wildly unrelated VTY commands.

Note: This will break users' config files if they do not use consistent
indenting. (see below for a definition of "consistent".)
When reading VTY commands from a file, use indenting as means to implicitly
exit child nodes. Do not look for commands in the parent node implicitly.
The VTY so far implies 'exit' commands if a VTY line cannot be parsed on the
current node, but succeeds on the parent node. That is the mechanism by which
our VTY config files do not need 'exit' at the end of each child node.
We've hit problems with this in the following scenarios, which will show
improved user experience after this patch:
*) When both a parent and its child node have commands with identical names:
cs7 instace 0
point-code 1.2.3
sccp-address osmo-msc
point-code 0.0.1
If I put the parent's command below the child, it is still interpreted in the
context of the child node:
cs7 instace 0
sccp-address osmo-msc
point-code 0.0.1
point-code 1.2.3
Though the indenting lets me assume I am setting the cs7 instance's global PC
to 1.2.3, I'm actually overwriting osmo-msc's PC with 1.2.3 and discarding the
0.0.1.
*) When a software change moves a VTY command from a child to a parent. Say
'timezone' moved from 'bts' to 'network' level:
network
timezone 1 2
Say a user still has an old config file with 'timezone' on the child level:
network
bts 0
timezone 1 2
trx 0
The user would expect an error message that 'timezone' is invalid on the 'bts'
level. Instead, the VTY finds the parent node's 'timezone', steps out of 'bts'
to the 'network' level, and instead says that the 'trx' command does not exist.
Format:
Consistent means that two adjacent indenting lines have the exact
same indenting characters for the common length:
Weird mix if you ask me, but correct and consistent:
ROOT
<space>PARENT
<space><tab><space>CHILD
<space><tab><space><tab><tab>GRANDCHILD
<space><tab><space><tab><tab>GRANDCHILD2
<space>SIBLING
Inconsistent:
ROOT
<space>PARENT
<tab><space>CHILD
<space><space><tab>GRANDCHILD
<space><tab><tab>GRANDCHILD2
<tab>SIBLING
Also, when going back to a parent level, the exact same indenting must be used
as before in that node:
Incorrect:
ROOT
<tab>PARENT
<tab><tab><tab>CHILD
<tab><tab>SIBLING
As not really intended side effect, it is also permitted to indent the entire
file starting from the root level. We could guard against it but there's no
harm:
Correct and consistent:
<tab>ROOT
<tab><tab>PARENT
<tab><tab><tab><tab>CHILD
<tab><tab>SIBLING
Implementation:
Track parent nodes state: whenever a command enters a child node, push a parent
node onto an llist to remember the exact indentation characters used for that
level.
As soon as the first line on a child node is parsed, remember this new
indentation (which must have a longer strlen() than its parent level) to apply
to all remaining child siblings and grandchildren.
If the amount of spaces that indent a following VTY command are less than this
expected indentation, call vty_go_parent() until it matches up.
At any level, if the common length of indentation characters mismatch, abort
parsing in error.
Transitions to child node are spread across VTY implementations and are hard to
change. But transitions to the parent node are all handled by vty_go_parent().
By popping a parent from the list of parents in vty_go_parent(), we can also
detect that a command has changed the node without changing the parent, hence
it must have stepped into a child node, and we can push a parent frame.
The behavior on the interactive telnet VTY remains unchanged.

Add OSMO_BIT_PRINT_EX() which is like OSMO_BIT_PRINT() but allows to
specify character to be printed for set bits. It's useful to print bytes
used as mask where set bit has particular semantics - for example TS
mask in OsmoPCU.

When doing UMTS AKA with AUTS, it can be interesting to know the SQN.MS that
was encoded in the AUTS. The only way to know this is to provide it as a
separate out-parameter from milenage_gen_vec_auts(), because the SQN.MS from
AUTS stored in umts.sqn is immediately modified non-trivially by
milenage_gen_vec(). Add sqn_ms to struct osmo_sub_auth_data to retain SQN.MS
even after a vector was generated.
Use this to print out SQN.MS for 'osmo-auc-gen -3 -A'.
Adjust test suite expectations.

This basically follows the concept of osmo_timer_setup() and allows
the caller to fill-in all configurable fields of osmo_fd in one
line of code, rather than open-coding it in 5 lines everywhere.

In the Protocol Configuration Options IE (see 3GPP TS 24.008 10.5.6.3)
there is yet another new TLV format (derived from PPP IPCP/LCP/...)
which uses 16bit tag and 8bit length. Let's add functions so we can
generate related TLVs. Parsing is unfortunately not possible in our
existing structure as our tlv_parsed array only has 256 entries and
thus cannot cope with 16bit tags.

In the course of splitting up the openbsc.git repository, we will create
libosmo-mgcp and need a library logging category for that purpose.
