2016-09-28Revert "bts: extend bts_chan_load to allow counting tch only"Neels Hofmeyr5-30/+7
This reverts commit 308cb0719dca3ba8eed1eff2a2124d44f34d9a28. Problems in this commit: openbsc/src/libbsc/chan_alloc.c:523: case GSM_PCHAN_TCH_F_PDCH: This is actually wrong, GSM_PCHAN_TCH_F_PDCH use ts->flags, not ts->dyn below (due to historical reasons and could be unified). 560: if (only_count_tch && !chan_is_tch(ts)) This has exactly one effect: it excludes GSM_PCHAN_TCH_F_PDCH when in PDCH mode, because for all other PDCH (plain PDCH and TCH/F_TCH/H_PDCH in PDCH mode) below ts_subslots() returns 0 and skips the for() loop. I consider this a bug in TCH/F_PDCH, to be fixed in an upcoming commit. I don't see why we need the only_count_tch argument, because this should normally only count TCH, weren't it for the TCH/F_PDCH bug. If dyn TS should be counted differently, we should do this in a different way. Change-Id: I34dbbaf53a800115e3d03bd44028cad675f3b525
2016-09-28channel_test: test nr of subslots for dyn pchan, with errorNeels Hofmeyr2-0/+32
Add test_dyn_ts_subslots() and call from main(). Update channel_test.ok. This includes erratic assert to show a bug for TCH/F_PDCH in PDCH mode: the nr of subslots should be the same as for a normal PDCH, i.e. zero. This will be adjusted along with the fix in an upcoming commit. Change-Id: I09685be3fb3ed1ead4577b772a9fbc31967980d1

2016-09-27log VTY telnet bind only onceNeels Hofmeyr6-12/+0
After libosmocore 55dc2edc89c1a85187ef8aafc09f7d922383231f which outputs 'telnet at <ip> <port>' from telnet_init_dynif(), there's no need to log the telnet VTY bind here anymore. Change-Id: I97a730b28759df1d549a5049f47a3da1c16a3447

2016-09-26mscsplit: directly access gsm_network backpointer from gsm_subscriber_connectionNeels Hofmeyr5-60/+53
The previous commit added a network backpointer to gsm_subscriber_connection. Use it wherever it makes sense, to skip the step through the bts structure. In some places, remove local variables that become unused. Change-Id: I34537025986713291e14c8212a81539b497befd4
2016-09-26mscsplit: add gsm_network backpointer to gsm_subscriber_connectionNeels Hofmeyr2-0/+3
We want to be able to use a network backpointer without having to go through a gsm_bts struct. This commit adds the network pointer, the subsequent commit applies direct access to the network structure from gsm_subscriber_connection. Change-Id: If8870972f1b3e333c2a4cce97cdc95bdee0382a1
2016-09-26mscsplit: abis vty: decouple from global bsc_gsmnet variableNeels Hofmeyr3-4/+6
Publish gsmnet_from_vty() in openbsc/vty.h and use in the abis VTY functions. Change-Id: Ib65a18db06b8bc4fc7d56bf56dd64a52cc1cd253
2016-09-26mscsplit: bsc_vty_init(): decouple from global bsc_gsmnetNeels Hofmeyr5-5/+5
Add an explicit gsm_network pointer instead of using the bsc_gsmnet global. This allows passing a gsm_network struct from the main() scope, which helps to decouple libmsc from libbsc. Change-Id: I9e2c0d9c18d4cebb5efb71565ad84df2bc2e0251
2016-09-26mscsplit: talloc_ctx_init(): decouple from global tall_bsc_ctxNeels Hofmeyr3-20/+19
Decouple the talloc context allocations from global tall_bsc_ctx pointer. It appears that talloc_ctx_init() was intended for general use, since it is located in libcommon. It is currently used only by osmo-nitb; but the upcoming osmo-cscn will use it as well. Instead of defining in osmo-nitb main file, add definition in gsm_data.h. Change-Id: I168106599b788f586be0ff0af4699b9746c1b103
2016-09-26mscsplit: gsm_network_init(): add explicit root talloc ctxNeels Hofmeyr7-9/+14
Decouple the root talloc context from libbsc's global talloc_bsc_ctx. This allows to define the root talloc ctx from a main() scope, which in turn helps decouple libmsc from libbsc. Change-Id: I92f6b47b1eeea2e8f3fba66f25d7e708e5659f8a
2016-09-26mscsplit: move subscriber conns list into struct gsm_networkNeels Hofmeyr5-10/+8
Replace the global sub_connections llist with gsm_network.subscr_conns. Initialize and apply where applicable. Remove bsc_api_sub_connections(), callers now access gsm_network->subscr_conns directly. This allows using the subscr_conns from libmsc without having to link libbsc. Change-Id: Ice2a7ca04910bcfaaff22539abe68a6349e8631c
2016-09-26mscsplit: bsc_init: don't pass telnet dummy connNeels Hofmeyr1-4/+1
We want to create the telnet for VTY only after reading the config file, and the dummy_conn was a workaround to be able to do so, but is not needed: gsmnet_from_vty() used to expect vty->priv to point to a gsm_network struct, but that is not actually the case anymore. It is using a static pointer to store the gsm_network struct instead. Change-Id: I51e7224c5a4cd5baf564bee871cf2fa6e885cda7

2016-09-24V.42bis: add sourcecode from IAXmodem (SPANDSP)Philipp3-0/+1031
V.42bis is a data compression method found in modems. It has also been specified for GPRS as data compression algorithm. The implementation has been taken from IAXmodem: https://sourceforge.net/p/iaxmodem/code/HEAD/tree/ svn checkout svn://svn.code.sf.net/p/iaxmodem/code/ iaxmodem-code Revision: r36 Change-Id: Iabedece9f97ca944a1e3f747bb073e532c4e9dca

2016-09-24RFC1144: add slhc code from linux kernelPhilipp2-0/+927
SLHC is an Implementation of RFC1144 TCP/IP header compression. We will need RFC1144 compression to compress GPRS TCP/IP traffic. The implementation pushed with this commit was taken from: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git commit 29b4817d4018df78086157ea3a55c1d9424a7cfc Change-Id: Ied69c143678dc4a64cecc671f5c4dfebe19d8519
2016-09-24SNDCP: add SNDCP-XID encoder/decoder and unit testPhilipp12-1/+2350
The SNDCP-XID (or layer-3 xid) is used to exchange layer-3 parameters such as compression. The encoder encodes a bytestream that is then sent as regular XID field from LLC. We will need the SNDCP-XID to negotiate the parameters for our upcomming GPRS data and header compression features Change-Id: If2d63fe2550864cafef3156b1dc0629037c49c1e

2016-09-18Sanity fixes for gsm0408_dispatch(): rc, assertionsNeels Hofmeyr1-0/+5
gsm0408_dispatch() is the main entry point for receiving data from the BSC/RNC level, so make sure callers pass valid pointers before using them all the way down the code path (related to CID#93769, a fix before this was refactored). For unknown/unimplemented packet discriminators, make sure to return error codes. Change-Id: Ieec39c74a53ef4dfa971dd935c8c9aa60fef58c1

smpp_try_deliver could fail with rc < 0. In such cases don't send the MS the rp error sms rejected (cause 21). A rejected message should not be sent again.
