2021-12-14treewide: remove FSF addressOliver Smith6-24/+0
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. Change-Id: I73be012c01c0108fb6951dbff91d50eb19b40c51
2021-11-15logging: use meaningful default loglevelsPhilipp Maier1-4/+4
Some logging categories use LOGL_INFO or even LOGL_DEBUG. Lets set those to LOGL_NOTICE to have a less crowded default log output. Change-Id: I3faefccae2218b17bd942bc2afac7d8e515897b7 Related: OS#2577

2020-03-10virtphy: Add command line arguments to set multicast netdev + TTLHarald Welte1-3/+15
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. Change-Id: Ia74aa381a4c1921cb8c7e263842a864ea8028139 Related: OS#2966
2020-03-10virtphy: Sync virtual_um.[ch] with osmo-btsHarald Welte3-26/+54
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).

2020-03-09virtphy: Fix GSMTAP ARFCN use with multi-TRX BTSHarald Welte5-14/+35
In case we get assignments to secondary TRXs, the ARFCN of that TRX must be used, and not the serving cell BCCH ARFCN. Change-Id: Ief6cf5816969d819ff9506be70bec9b8d0d9d9be
2020-03-09virt_phy: implement GSMTAP_CHANNEL_VOICEHarald Welte3-14/+63
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. Change-Id: Id72cf23b7c6587efae4cdaa7b50ab4d85b8c8d22
2020-03-07virtphy: Don't pass CBCH to L1CTL if not requested by applicationHarald Welte1-1/+5
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) <0015> lapdm.c:481 sending MDL-ERROR-IND 12 <0001> gsm48_rr.c:4977 MDL-Error (cause 12) ignoring Change-Id: I2cf65be5b2f879fe940e08c9f369bc1cada7b0dd Closes: OS#4439
2020-03-07virt_l1_sched_execute: talloc_free() TDMA item after unlinking itHarald Welte1-0/+1
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. Change-Id: I57a596428be10ce720e0b528ecfc44a70e3e3078

2018-11-05l1ctl_proto.h: use flexible array member for traffic messagesVadim Yanitskiy1-1/+5
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. Change-Id: I119fa36c84e95c3003d57c19e25f8146ed45c3c6

There is no helptext for the commandline options, which makes it difficult for new users to use the program. - Add commandline help Change-Id: I8d04644342acd64432742f96e32dc9f2e0e91c20

2018-08-24osmo_mcast_sock: make sure SO_REUSEADDR is appliedPhilipp Maier1-2/+3
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 Change-Id: Ia1014ac5e0522e77178249cdc6398dec2168bffe Depends: libosmocore I1399a428467ca12f1564a14eb8ffb294d4f59874 Related: OS#3497

Move corresponding .gitignore entry inside virt-phy to avoid interfering with other subprojects still using hand-crafted Makefiles. Change-Id: I19a8661b74ae0b28da51cf2e81f0ca40de76fcbd
2017-10-23mobile: clean up and share example configsVadim Yanitskiy2-187/+0
It is better to have a shared example config files directory, like other Osmocom projects do. Change-Id: I903f31a8afc518ac258cdaeaf76430de07f7edea
2017-08-20VIRT-PHY: Add support for GPRS / TBF modeHarald Welte3-5/+249
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
2017-08-20VIRT-PHY: virt_l1_sched: Pass timeslot number into call-backHarald Welte7-10/+10
When we schedule a given frame for transmission, we save its timeslot number. However, the callback doesn't get informed about this so far. Change-Id: I608a91ae8e2a57a2d6f87f4b873c82edb0215bf6

2017-07-19VIRT-PHY: enable proper memory leak debuggingHarald Welte2-3/+26
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. Change-Id: I73b3cf86eea5f56595c1b045cf0fde8035ff185a
2017-07-19VIRT-PHY: We don't do line-breaks inside log statementsHarald Welte1-3/+1

2017-07-19VIRT-PHY: Properly destroy l1_model_ms after disconnectHarald Welte7-1/+33
If a MS disconnects, we need to clean up all related state Change-Id: Ib7adef61150b5a4338483019e4dd75d7279d1f5d
2017-07-19VIRT-PHY: Change default log levelsHarald Welte1-1/+1
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. Change-Id: I9513db3cee12644ed9b9858e13b740ffd27aba24
2017-07-19VIRT-PHY: Clean up logging statementsHarald Welte7-59/+66
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. Change-Id: If06a8b5f99349796d66a71201524361a6547945a
2017-07-19VIRT-PHY: Separate logging of L1 Control and L1 DataHarald Welte6-7/+37
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
2017-07-19VIRT-PHY: Log MS context number whenever possibleHarald Welte13-45/+71
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.

2017-07-13VIRT-PHY: Use IPv4 multicast groups for private / local scopeHarald Welte1-2/+7
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 Change-Id: I8e3acd745e65a6cfa70b681a440da6a59a1ed0b5
2017-07-13VIRT-PHY: Use osmo_fd_close() introduced in libosmocoreHarald Welte1-15/+4
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. Change-Id: Id8a518dfb09465c2765681407e5581aee2d62d6d
2017-07-13VIRT-PHY: Use new OSMO_SOCK_F_NO_MCAST_{LOOP,ALL} flagsHarald Welte1-36/+8
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. Change-Id: I961aa07a381fef2cf9a2fb5357937864364ca04b
