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.

Some logging categories use LOGL_INFO or even LOGL_DEBUG. Lets set those
to LOGL_NOTICE to have a less crowded default log output.

This allows us to bind the multicast sockets to a given network device
and/or to set the TTL of the multicast frames and hence control their
reach in terms of number of network hops.

The files are used in both projects, and while the osmo-bts code has
evolved, this copy didn't. Let's sync again (to libosmocore
change-Id I303f2e616d2d32b5a8005c3dcf0f5fad19ad3445).

In case we get assignments to secondary TRXs, the ARFCN of that
TRX must be used, and not the serving cell BCCH ARFCN.

GSMTAP_CHANNEL_VOICE is the mechanism by which GSMTAP can [finally!]
be used to transport circuit-switched voice codec payload, and not
just signalling.
Original patch by Neels Hofmeyr, heavily extended by Harald Welte.

Doing so can create a number of warning messages in e.g. 'mobile'
like
<0015> lapd_core.c:1239 Unnumbered frame not allowed. (dl=0x55c632f9f220)
<0015> lapd_core.c:392 sending MDL-ERROR-IND cause 12 from state LAPD_STATE_IDLE (dl=0x55c632f9f220)

We so far relied on it being free'd once the TDMA item is free'd,
but let's make it more explicit. After we've unlinked it from the
list, nobody is going to reference it ever again.

Unlike the DATA messages, traffic frames may have different length.
Instead of having fixed payload (i.e. TCH frame) length, let's
introduce a flexible array member. This would allow one to
calculate the frame length using the MSGB API.

There is no helptext for the commandline options, which makes it
difficult for new users to use the program.
- Add commandline help

virtphy uses UDP multicast to communicate with its osmo-bts-virtual
counterpart. At the momemnt SO_REUSEADDR is not applied for those
multicast connections because OSMO_SOCK_F_UDP_REUSEADDR is not set. This
makes prevents the proper function of UDP multicast.
- Make sure OSMO_SOCK_F_UDP_REUSEADDR is set

Move corresponding .gitignore entry inside virt-phy to avoid interfering
with other subprojects still using hand-crafted Makefiles.

we add a new STATE_TBF to vthe MS model and add some L1CTL primitives
to configure that TBF mode as well as to enqueue transmissions for
blocks at a given USF+TS.
Change-Id: Ie6f37090bd45f463aa25d9e00bc06f563be5264a
When we schedule a given frame for transmission, we save its timeslot
number. However, the callback doesn't get informed about this so far.

We make sure that all allocations are tracked back to one talloc root
context, and install the usual SIGUSR1 handler to dump the talloc
report. This enables us to do interactive debugging for memory leaks
while virtphy is running.

This will basically only print L1C message for all L1CTL happening
between MS and the BTS, while suppressing the GSMTAP/virtUM and L1P
related messages.

The generated log lines have been *super* long, let's make them
significantly shorter. Also, differentiate between DEBUG and INFO
level, so normal operation with LOGL_INFO will not spam the user while
still printing useful information.

L1 Data is quite verbose, while control is typically limited, so let's
make sure we log them as separate sub-systems
Change-Id: Idebc371a63508c593855486ff01b2ba6e8c2cfd1
Now that we can have multiple MS connected to one virtphy instance,
it is important to log some context whenever possible. To do so, we
introduce a monotonically increasing MS number which gets assigned
whenever we allocate a l1_model_ms and printed when the LOGPMS() or
DEBUGPMS() macros are used.

* l1_model_ms can become a static member of l1_model_ms

The addresses in the original code make little sense:
* 224.0.0.1 is "All systems on this subnet" and not routed
outside the local ethernet segment
* 225.0.0.1 is in a RESERVED range that shouldn't be used

libosmocore has recently received a new function osmo_fd_close() which
can be used to replace the private fd_close() function in this code.
This requires Change-Id Icd0933eed6a24edde7cdcb378e138897ecc5332c in
libosmocore.

libosmocore has recently gained support for flags like
OSMO_SOCK_F_NO_MCAST_LOOP and OSMO_SOCK_F_NO_MCAST_ALL that can be
passed to the socket initializer functions, further reducing complexity
of the code in osmo_mcast_sock.c here.
The related change-IDs are I5ab5de45c0b64ceb3636ea98245a23defa24ffd4 and
I24a5b1ebc3f84d2d5d4734e54df50efaea26490b in libosmocore.git.
