* osmo_sock_init2(): Fix creation of non-bound socketsHarald Welte2017-07-211-1/+1
| | | | | | | | | If osmo_sock_init2() was used with CONNECT flag but without BIND flag, an invalid check for "did we create a socket yet" caused the socket to never be created, and subsequently the entire function to return an error. Change-Id: I0206dbb9c5b8f74d7fb088576941b092acd2ca22
* socket: Add new OSMO_SOCK_F_NO_MCAST_ALL optionHarald Welte2017-07-131-0/+10
| | | | | | | Using this option at socket creation, the caller can request disabling the IP_MULTICAST_ALL socket option. Change-Id: I5ab5de45c0b64ceb3636ea98245a23defa24ffd4
* socket: Allow disabling multicast loop on socket creationHarald Welte2017-07-131-4/+16
| | | | | | | | | | | This introduces a new flag OSMO_SOCK_F_NO_MCAST_LOOP, which can be used to disable the looping back of multicast packets transmitted throug this socket to other local sockets on the machine. As this looping-back is active by default, a single option to deviate from the default is deemed sufficient. Change-Id: I24a5b1ebc3f84d2d5d4734e54df50efaea26490b
* socket: Unify listen() calls and check for erroneous returnsHarald Welte2017-07-131-20/+33
| | | | | | | | | We had three places at the end of socket initialization functions calling listen(). Let's unify that and fix some bugs: * close + return error in case of bad listen() result * don't call listen() on AF_UNIX SOCK_DGRAM sockets Change-Id: I7e8dbe3c0486bb3b9810b0add1331e93fc106d82
* socket.c: Add multicast related convenience functionsHarald Welte2017-07-131-0/+135

* osmo_sock_get_name(): clearly indicate local and remoteNeels Hofmeyr2017-07-031-2/+2
| | | | | | | | | | | | | | | | In a string like 127.0.0.1:2905<->127.0.0.1:60661 it is hard to tell which is the local part. I'd have expected it on the left, but it is actually on the right. To avoid doubt and bypass bikesheds on which side should be what, clearly mark the two sides as remote and local. (r=127.0.0.1:2905<->l=127.0.0.1:60661) Change-Id: I43dcc6a1906429bd0955fd7fe2eb5b8495b592d8
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-4/+3
| | | | | | | | | | | | | | | | | Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-231-11/+11
| | | | | | | | | | Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
* update/extend doxygen documentationHarald Welte2017-06-121-3/+2
| | | | | | | | | It's a pity that even with this patch we still are fare away from having the whole API documented. However, at least we have a more solid foundation. Updates not only extend the documentation, but also make sure it is rendered properly in the doxygen HTML. Change-Id: I1344bd1a6869fb00de7c1899a8db93bba9bafce3
* socket: Add osmo_sock_init2_ofd() functionPau Espin Pedrol2017-05-261-0/+23
| | | | | | Will be used by osmo-bts-trx Change-Id: I3c655a4af64fb80497a5aaa811cce8005dba9cd9
* Add osmo_sock_init2() function, allowing both BIND *and* CONNECTHarald Welte2017-04-091-33/+187
| | | | | | | | | The old osmo_sock_init() function allows only either a bind (for a server socket), or a connect (for a client socket), but not both together. So there's no way to have a client socket that is bound to a specific local IP and/or port, which is needed for some use cases. Change-Id: Idab124bcca47872f55311a82d6818aed590965e6
* cosmetic: replace fprintf with LOGPPhilipp Maier2017-02-091-8/+12
| | | | | | | socket.c still uses fprintf to output error messages. This commit replaces the fprintf with proper LOGP messages. Change-Id: Ia2993415d5f5c33ccd719af239ff59252d11b764
* socket: Introduce function to obtain socket nameHarald Welte2017-01-271-1/+43
| | | | | | | Using this function, one can obtain a human-readable string identifying the host and port names of the socket. Change-Id: Ib5de5c7b9effe1b0a363e4473a7be7fa38ca6ef3
* osmo_sock_init(): Fix memory leak in error pathHarald Welte2016-11-261-0/+1
| | | | | | | We forgot to call freeaddrinfo() in an error path. Change-Id: Iccbd3beef4c4a70dc443131b909c45e650d8c6a2 Fixes: Coverity CID 135217
* fix printf format for commit 'osmo_sock_init(): include host and port in ↵Neels Hofmeyr2016-08-291-1/+1
| | | | | | | error messages' Related: CID#143566 Change-Id: I75c542089749a0875d3d1913151fe838d7722ff2
* osmo_sock_init(): include host and port in error messagesNeels Hofmeyr2016-08-271-5/+16
| | | | | | | | | | | For programs like osmo-hnbgw with numerous sockets, the message that some unspecified connection was refused is not very helpful. Also output the host and port where an error occured. Instead of perror, use fprintf(stderr, ..., strerror()) to be able to include a format string and print host and port as passed to osmo_sock_init().

* Update doxygen annotations in libosmocoreHarald Welte2016-05-051-0/+6
| | | | | This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.

* add missing copyright statements to source code filesHarald Welte2014-09-111-0/+21
| | | | | | Some source code files didn't have the usual copyright and licence statement at their top. I'm adding them baesed on information in the commitlog.
* src/socket: Adding unix domain socket supportÁlvaro Neira Ayuso2014-03-261-0/+102
| | | | | | Added some function for adding the unix domain socket support. Signed-off-by: Alvaro Neira Ayuso <anayuso@sysmocom.de>
* misc: Doxygen tweaks: fixed some typos and minor errorsKaterina Barone-Adesi2013-02-151-1/+1
| | | | | Doxygen generates quite a lot of warnings on libosmocore. Some of them are obvious typos - this patch aims to fix such low-hanging fruit.
* socket: fix osmo_sock_init with SOCK_RAW and IPPROTO_RAWPablo Neira Ayuso2013-01-151-3/+16
| | | | | | | | | | | | | getaddrinfo returns EAI_SERVICE (-8) if that combination is used. More information available in here: http://sourceware.org/bugzilla/show_bug.cgi?id=15015 Reported by Holger Hans Peter Freyther. While at it, this patch also removes hints.ai_flags = 0 as memset to zero already happened just a bit before that.

* sync prototype of osmo_sockaddr_is_local with declarationHarald Welte2012-04-081-1/+1
| | | | | in e476442cf0e84c65565ace545f5b73602b5f0ffc we changed from sockle_t to unsigned int, but only in the header, not in the implementation!
* freebsd: Fixes for the compilation of libosmocore on FreeBSDHolger Hans Peter Freyther2011-11-091-0/+2
| | | | | | | | | | | alloca.h is not available on FreeBSD, use the default autoconf function to check for it, there is a complete list[1] of what to do for using alloca but let us see how far we get with this test. Include netinet/in.h for the IPv4 and IPv6 socket address. Check for dlopen in libraries and use this instead of linking -dl. [1] http://www.gnu.org/s/hello/manual/autoconf/Particular-Functions.html
* some more doxygen work (include the notion of modules)Harald Welte2011-08-171-1/+48

* socket: add OSMO_SOCK_F_[CONNECT|BIND|NON_BLOCK] flagsPablo Neira Ayuso2011-06-131-10/+28
| | | | | | | | This extends the socket infrastructure in libosmocore to allow to create non-blocking sockets. Basically, it replaces the connect0_bind1 parameter by one flags parameter.
* socket: getaddrinfo(): set AI_PASSIVE if we want to bindHarald Welte2011-05-311-0/+3
| | | | This will tell getaddrinfo() that we want a INADDR_ANY style socket
* socket: remove unused IPv4 related header includesHarald Welte2011-05-291-2/+0

* socket: Skip ifa's without ifa->ifa_addrHarald Welte2011-05-241-0/+2
| | | | Apparently getifaddrs() returns ifa's without an ifa_addr set.
* socket: use listen() and SO_REUSEADDR, new osmo_sock_init_ofd() functionHarald Welte2011-05-221-1/+34
| | | | | | osmo_sock_init_ofd() is a wrapper around osmo_sock_init() which will take care of initializing and registering a 'struct osmo_fd' for the newly-created socket.
* remove debug printf from socket.cHarald Welte2011-05-221-1/+0
