2023-01-25Introduce netdev APIPau Espin Pedrol2-0/+50
This module provides several operations on network devices (interfaces), like monitoring changes, setting addresses, routes, link state, etc. It also supports managing network interfaces on several different netns concurrently. These functionalitites will be used by the tun module included in a follow-up patch. Change-Id: I7a00c0445a89e088676a4897061b65196d9197f1

2023-01-21create libosmoisdn sub-libraryHarald Welte6-291/+301
There are some parts of libosmogsm which are not really GSM specific, but rather ISDN bits that were inherited by GSM. This includes the I.460 multiplex as well as the core LAPD protocol. Let's move those bits to its own libosmoisdn library, before we add more ISDN specific bits to the wrong place. Backwards-compatibility is created by making libosmogsm depend on libosmoisdn, and by providing wrapper include files for source compatibility. Change-Id: Ib1a6c762322fd5047be3188b1df22408ef06aa50
2023-01-18Split include/Makefile.am content into subdirsPau Espin Pedrol14-225/+292
When someone is modifying a given library there's no need to be looking at a common file contains tons of lines from different libraries. Furthermore, this removes the need of "nobase" autofoo prefix, hence following the usual directive of having one Makefile per directory. Change-Id: I785891c2f89114bf8303c799094b637d3d25ac71

2022-12-20ctrl: add optional port to bind commandMax2-3/+9
So far ctrl interface did not allow to specify port to bind to. Let's fix this and make it consistent with the way vty bind works. N. B: the functions which ignore port configured via vty are marked as deprecated, the sw which uses them should be ported to either newly added ctrl_init_default() or simplified ctrl_interface_setup() The similar change for vty interface will be addressed via separate patch series.

2022-12-14gsm0808: add gsm0808_enc_speech_codec[_list]2()Vadim Yanitskiy1-3/+8
The problem with most of the existing gsm0808_* functions in this file is that they assert() too much, assuming that their callers always pass perfectly valid input parameters. But this is impossible on practice, as there can be bugs in complex projects using them, liks osmo-bsc. It was reported by a customer that a heavily loaded osmo-bsc crashed a few times, dropping more than 100 sites without network coverage for a few minutes. As was revealed during the investigaion, it crashed due to a failing assert at the end of enc_speech_codec(): OSMO_ASSERT(sc->cfg == 0); The problem is that somehow osmo-bsc is passing an unexpected sc->cfg value to gsm0808_create_ass_compl2(), in particular 0x02, while the given sc->type value (GSM0808_SCT_HR1) implies that there cannot be any configuration bits on the wire. The reason why and under which circumstances this can be happening is not clear yet, but what we agreed on so far is that the library API should be enforcing correctness of the input parameters in a less agressive way, rather than aborting the process without letting it any chance to recover. Modify the original gsm0808_enc_speech_codec[_list]() functions, so that a negative value is returned in case of an error. Rename them and add backwards compatibility wrappers, because it's public API. A separate patch making use of the new API follows next.

2022-12-02gsmtap.h: Add definitions for various ISDN sub-typesHarald Welte1-0/+5
We've started to encapsulate a varieth of ISDN related formats as sub-types to GSMTAP_TYPE_E1T1 for quite some time. Let's add some more formats, such as V5EF, V.110, V.120, X.75 and H.221 For the HDLC based V5EF, V.110, V.120 and X.75 the payload format is clear. For V.110 and H.221 we will need to specify how the actual payload looks like. Change-Id: I8dee0f730cf91d6f9133d5c57f653e669ec8d598

2022-11-07vty/logging.h: Avoid -Werror=pragmas error in C++ codeHarald Welte1-0/+1
The newly-introdiced pragma to disable strict-prototypes checking works in C, but creates a -Werror=pragmas error in C++ code: In file included from osmo-trx.cpp:45: /build/deps/install/stow/libosmocore/include/osmocom/vty/logging.h:10:32: error: option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ [-Werror=pragmas] #pragma GCC diagnostic ignored "-Wstrict-prototypes" So let's also suppress those errors for that one line of code...

2022-11-06Disable -Wstrict-prototypes for logging_vty_add_cmds()Harald Welte1-1/+6
Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However, its declaration in C file didn't contain "(void)", which meant the number of parameters is undefined and thus compiler doesn't complain. However, in recent Change-Id I84fd99442d0cc400fa562fa33623c142649230e2 we changed the declaration to '(void)' to allow building with -Wstrict-prototypes. This caused downstream build-failures of osmo-mgw (1.4.0) and osmo-e1-recorder (master). So let's make one very small-scoped exception here. Change-Id: Iadb54848b67db937b640dc2102dddb6e708a6a9f

When any of l1h, l2h, l2h or l4h is set to NULL (which is the default for newly allocated message buffers). Then the msgb_lXhlen() functions will return the address value of msgb->tail. This can lead to unexpected results at a later point. We should have an OSMO_ASSERT to catch the problem early. Change-Id: I1795c559f190713ebbabfbabf3453ab77da46a49 Related: OS#5645

This reverts commit a4063efa7deb6632c228037c47effca22ad0f781. Reason for revert: It is not possible to guess the IP address family from uninitialized memory.

This reverts commit e145e28a91eeca65d34d7b82caa2190fa89492b4. Reason for revert: The function osmo_sockaddr_strs_to_str() should not be part of the osmo_sockaddr_str API. The implementation of this should live in the function multiaddr_snprintf() added in patch Icef53fe4b6e51563d97a1bc48001d67679b3b6e9 and should not use dynamic allocation.

This is similar to what we already do between BSC<->MSC to pass Osmux CID (GSM0808_IE_OSMO_OSMUX_CID).
