* gsmtap_util: make sure SO_REUSEADDR is applied for GSMTAPPhilipp Maier2018-08-241-1/+3
| | | | | | | | | | | | | | When gsmtap adding a new sink it does not supply OSMO_SOCK_F_UDP_REUSEADDR in order to have SO_REUSEADDR applied. In most cases, the gsmtap sink is just receiving packets to toss them immediately, so having one of them is sufficient. However, in other use cases - particularly virt_phy - we actually want to receve and process GSMTAP messages via multicast Applying SO_REUSEADDR (like we did before disabling it globally for UDP in I4a8ffb8d598aca88801a4a0322944d7cdd8d4047 on August 1st) resolves the issue.

* memleak: fix all libosmocore callers of gsmtap_sendmsg() to free on failureNeels Hofmeyr2018-02-161-1/+5
| | | | | | | gsmtap_sendmsg() does not free the msgb if it returns a failure rc, so the callers must check the rc and free the msg. Change-Id: I7cf64ed9b14247298ed8b4ab8735627f8235a499
* memleak: gsmtap_sendmsg(): don't return 0 when no data was writtenNeels Hofmeyr2018-02-161-1/+1
| | | | | | | | | | | | If less than the msgb size was written by write(), we want to return -EIO. Hence do not return zero when write() wrote zero bytes, return -EIO in that case as well. Previously, if write() returned zero, gsmtap_sendmsg() would return zero *without* freeing the msg, hence neither would the (ideal) caller. So this fixes a corner-case memleak.

* gsmtap_sendmsg(): clarify API doc concerning msgb ownershipNeels Hofmeyr2018-02-161-0/+3
| | | | | | | | | | | | Not freeing on error does enable callers to try to re-send as well, so it is a kind of useful feature, even though I find it likely for callers to either forget about freeing the msg on error or double-free by accident... I considered changing gsmtap_sendmsg() to always free, but since it is public API, I chose to keep and document its current behavior properly instead. We don't know what callers may exist out there.

* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-4/+5
| | | | | | | | | | | | | | | | | 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 Welte2017-06-121-0/+1
| | | | | | | | | 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

* Remove direct loggingMax2017-01-061-3/+0
| | | | | | | | Drop perror() calls from GSMTAP code: it's application job to do the proper logging - library code should not write to stdout/stderr directly. Change-Id: Ifa149e65d76c6e64fda2946725c16672233aff2e

* Update doxygen annotations in libosmocoreHarald Welte2016-05-051-1/+20

| | | | | Doxygen generates quite a lot of warnings on libosmocore. Some of them are obvious typos - this patch aims to fix such low-hanging fruit.

* GSMTAP: add function to create a 'sink' for gsmtap packetsHarald Welte2011-05-041-2/+55
| | | | | | This can be helpful where we send GSMTAP messages to the loopback device (localhost, 127.0.0.1) from where the kernel would then send ICMP reject packets as nobody is listening on that port.

| | | | | | | | | | | | This patch moves all GSM-specific definitions to include/osmocom/gsm. Moreover, the headers in include/osmocore/ have been moved to include/osmocom/core. This has been proposed by Harald Welte and Sylvain Munaunt. Tested with `make distcheck'. Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
