5 daysstream_{cli,srv}: Add 'res' param to read_cb2HEADpespin/streammasterPau Espin Pedrol4-4/+35
Notify user about read errors, similar to what is supported in the earlier ofd cb backend of osmo_stream_cli/srv: https://osmocom.org/issues/6405#note-15 Related: OS#6405 Fixes: 5fec34a9f20c3b8769373d1b28ae2062e5e2bdd6 Fixes: 0245cf5e07855abea72693272c55b50b5a93aff4 Change-Id: I395c75ff1e9904757ce1d767a9ac2f779593c4c8

2024-03-07stream_{client,server} example: Cleanup on exitAndreas Eversberg2-4/+21
In order to detect memory leaks while debugging, stream server/client and keyboard is closed on exit. Related: OS#5753 Change-Id: I9dbb7f46b2a798e88ad4df8ff73c6ee40c07b843
2024-02-29stream_{cli,srv}: Fix memory leak, if sending a message failsAndreas Eversberg2-3/+3
Also the example client/server must not access msgb after sending it, especially if the msgb got freed due to a failure. Change-Id: I627a71b4f0183cd83835c328a5cdd67a413ae614
2024-02-28examples/stream-{server,client}: Generate talloc report on SIGUSR1Harald Welte2-0/+22
This can help with memleak debugging. Change-Id: Ia16632602b937db88e2da2b053192887bdb8a986
2024-02-28examples/stream-*: Add options, to set local/remote peerAndreas Eversberg2-7/+14
This helps to test connections via a network and failing connections. The client may add "-r <peer>" to the command line, to set the address of the remote peer. The server may add "-l <peer>" to the command line, to select address of local peer. By default "127.0.0.1" is used. Change-Id: Ie6da55ef248436e521c5d8f21f8053356c46a114

2023-10-02stream: Add client-side (segmentation) support for IPAarehbein2-3/+8
With this commit, IPA segmentation is taken care of by setting the segmentation callback provided by libosmo-netif. The ipa-stream-server example needs to prepend IPA headers now because those are stripped by the segm. cb on both sides.

2023-06-20stream: Drop name param from recently added API osmo_stream_srv_create2()Pau Espin Pedrol2-2/+4
It was later decided that since setting a name is not really required, it is best to leave it out of the create() function and let the user use the osmo_stream_srv_set_name() API if needed (otherwise a dynamic name based on socket is selected) Change-Id: I5d677ef57b7db0aedd8c43282568c845097cb12b

2023-05-31ipa-stream-server: Return -EBADF in read_cb after osmo_stream_srv_destroy()Daniel Willmann1-1/+2
This fixes a potential heap-use-after-free error. When there is still data to be written the osmo_stream_srv_cb() will call osmo_stream_srv_write() which will try to dereference conn even though it has already been freed. Change-Id: I5ac1920b8d4ce3b0205f00d253e7ed878fb745e3

2022-09-02osmux: Allocate struct osmux_out_handle through APIPau Espin Pedrol1-5/+7
Until now, the osmux_out_handle was allocated by the client, and passed to the API to initialize it. This makes it really hard to improve the implementation without breaking the ABI. Let's break the ABI now one last time (hopefully) by allocating the struct through an API. With only this change, the already built users (osmo-mgw, openbsc) can still work fine, since there's no change on the struct osmux_out_handle. However, they will somehow break next time the struct is changed until they are ported to the same API (easy to do). Related: OS#5987 Change-Id: Ie8df581f375c9a183a7af60b431561bda82f6e34

2021-02-11Don't depend on libosmo-abis (by default)Harald Welte1-2/+3
The only reason we have a libosmo-netif -> libosmo-abis dependency is the lapd examples whihc are built but not even installed. Let's build those only if --enable-lapd-examples is specified at the command line, and remove the dependency to libosmo-abis in all other cases.

2020-05-09Use OSMO_FD_* instead of deprecated BSC_FD_*Pau Espin Pedrol3-3/+3
New define is available since libosmocore 1.1.0, and we already require 1.3.0, so no need to update dependenices. Let's change it to avoid people re-using old BSC_FD_* symbols when copy-pasting somewhere else. Change-Id: I269690c1c9e4d19b5b69eef206b95e71f7931188
2019-02-20Stream client: add disconnect callbackMax2-0/+16

Set category filter to make sure internal library logging won't interfere with example's own logging. It's also nice example illustrating log_set_category_filter() usage. Change-Id: I17d7878d302f011d8ff0d86708d677f5b559299e
2018-08-01Migrate from osmo_ipa_idtag_parse() to ipa_ccm_id_resp_parse()Harald Welte1-2/+2
In libosmocore Change-ID I1834d90fbcdbfcb05f5b8cfe39bfe9543737ef8f we have introduced ipa_ccm_id_resp_parse() as a bugfixed replacement of ipa_ccm_idtag_parse(). The main difference is that the returned "value" parts now have a correct reported "length", whereas before this commit they all reported a one-byte too-long "length" for each IE. Let's use this opportunity to remove the copy+pasted osmo_ipa_idtag_parse() function from the libosmo-netif codebase. Change-Id: I4626d247626543e032593bf226b6c233f6678562
2018-06-29remove "channel" layerHarald Welte4-187/+0
The "channel" layer on top of IPA client + server was introduced in 2011 but never used in any osmocom program/project so far. Contrary to the several other IPA multiplex related implementations in libosmo*, it did not deal properly with segmented IPA messages, i.e. where a single TCP segment (and hence recv/read call) does not contain a full IPA message. So rather than fixing it up and having yet another IPA related API in our libraries, let's remove it. Change-Id: I97c378750acb1637ee032fa88a968edf68d8979f
