Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

Replace some with atoi(), where the VTY has already validated correct
range of the argument.
Replace others with the new osmo_str_to_int() or osmo_str_to_int64()
functions, possibly covering more detection of invalid number strings.
Leave those strtol() callers that depend on endptr to provide the next
string token.

Use base '0' of strtoul to permit both decimal and hexadecimal input
to the SQN parameter. Some other tools represent the SQN as hex,
so this avoids having to use some external tool to convert and allows
you to copy+paste it to the osmo-auc-gen command line.

The positions of arguments in the call to "milenage_check" do not
match the ordering of the parameters:
* "ck" is passed to "ik"
* "ik" is passed to "ck"
Let's simply reorder the arguments of milenage_check()
to match the ordering in milenage_f2345().

So far we only looked at SW definitions of the card profile. However,
if we have a currently selected application, we also must check
that application for SW definitions.
This breaks ABI and API all over the place, but as there are no
known users beyond osmo-sim-test, this is acceptable.

an USIM application can very well exist on a UICC without supporting
classic DF.GSM access. However, most commonly, both are found on
cards.
Change-Id: I6180a3f81a7d3006e8ece4302c2433db2588bfaa
Before this change, a card application (USIM, ISIM, ...) didn't
exist as a separate concept from a card profile. This meant,
we had a manual combination of UICC card profile with USIM application,
and another one of UICC card profile and ISIM application. But what
if there's a combined USIM+ISIM?
In reality, applications exist as separate objects, on top of an
ETSI UICC. Lets therefore register all known applications to the
osim library core, and add code to osmo-sim-test which dynamically
detects all applications present on a given card (by reading EF.DIR).

Using the new '--output-dir' command line argument, the user can
instruct osmo-sim-test to dump the file content to a local directory.
osmo-sim-test will create one sub-directory per DF, and create a
text file for each EF. The contents of the text files are a hexdump
of the contents. Transparent EF are dumped as one line of hex,
while linear fixed EF are dumped as one record per line, i.e. the
number of lines corresponds to the number of records.

The variable struct tlv_parsed tp in dump_file() conditionally
initalized by tlv_parse() but later it is accessed under a different

sure tp can not be accessed when it is uninitalized.

log_enable_multithread() enables use of locks inside the
implementation. Lock use is disabled by default, this way only
multi-thread processes need to enable it and suffer related
complexity/performance penalties.
Locks are required around osmo_log_target_list and items inside it,
since targets can be used, modified and deleted by different threads
concurrently (for instance, user writing "logging disable" in VTY while
another thread is willing to write into that target).
Multithread apps and libraries aiming at being used in multithread apps
should update their code to use the locks introduced here when
containing code iterating over osmo_log_target_list explictly or
implicitly by obtaining a log_target (eg. osmo_log_vty2tgt()).

That's pretty straightforward and convenient extention: handle all
extra positional arguments as patch file names. This makes it similar to
'cp' and other coreutils basic tools. For example:
osmo-config-merge base.cfg patch1.cfg patch2.cfg patch3.cfg
will apply 3 patches to the base config file.

ARFCNs are values in well defined ranges. Until this patch, ARFCNs not
belonging to any band were blindly assigned to DCS1800 by
gsm_arfcn2band, causing unnoticed bugs and misconfigurations in
osmo-bsc.
Previous API gsm_arfcn2band cannot accomodate this kind of check easily,
so let's deprecate it to tell people to use a new API gsm_arfcn2band_rc
which performs this kind of checks and allows callers to log failures,
misconfigurations, etc.
At the same time, modify implementation of gsm_arfcn2band to abort if an
invalid ARFCN is passed, this way users of this API can notice they are
passing wrong data to it that most probably will produce unexpected
results.

This utility allows you to merge an incremental config "patch"
into an osmocom-style config file.
The patch file follows the same syntax as the original config file.
It works by appending the leaf nodes of the patch file to the respective
nodes of the input config file.
This process allows configuration file changes/updates to be performed
in a more stable/reliable way than by means of [unified] diff files,
as they break every time the context lines break.
osmo-config-merge doesn't suffer from this problem, as it understands
the tree-like nature of VTY config files.
NITE: This only works with configuration files that have proper
indenting, i.e. every level in the hierarchy must be indented excatly
one character, not multiple.

The function is a wrapper on top of getrandom() (if available via glibc) or
corresponding syscall. If neither is available than failure is always
returned.
It's intended to generate small random data good enough for session
identifiers and keys. To generate long-term cryptographic keys it's
better to use special crypto libraries (like GnuTLS for example)
instead.
As an example it's used to replace old insecure random number generator
in osmo-auc-gen utility.
