* egprs: Add CPS tables from TS 04.60Tom Tsou2016-07-253-1/+109
| | | | | | | | Includes EGPRS coding and puncturing scheme (CPS) tables from 3GPP TS 04.60. Currently osmo-bts-trx is the only user of CPS table values, but this may change with gprsdecode and other utilities. Change-Id: I09fe6514a0e2e51bb3206f8387633f7e0255345f

* bitvec: Force inlining of bitvec_set_bit_pos/bitvec_set_bitHolger Hans Peter Freyther2016-07-161-2/+2
| | | | | | | | | | | | | | The PCU is using bitvec_write_field a lot but on the arm-poky-linux-gnueabi-gcc v4.8.1 the calls to set_bit and set_bit_pos are not inlined. The inlined variant has been a more quick for the PCU compressed bitmap decompression testcase. Used objdump -d to look at the bitvec_write_field before and after the change. The branch to bitvec_set_bit is gone and a inlined version has been used. Change-Id: I0b6b90610f4c17f02e4efa064c3bf1ac2dccb22a

* fsm: delete the timer when changing stateHarald Welte2016-07-101-0/+3
| | | | | | | In osmo_fsm_inst_state_chg(), we need to stop any not-yet-expired timer of the old state before transitioning into the new state. Change-Id: I2558f9a7027a877ea8263785ed3c8d70d2513996
* fsm: talloc + copy the 'id' passed into a FSMHarald Welte2016-07-101-1/+2
| | | | | | | | | | The 'id' is used to generate the human-readable name of the FSM. However, when the FSM creates slave FSMs later, the caller-passed "ID" mgiht long be gone again (e.g. it was on stack memory). So let's copy the 'id' string to a chunk of dynamically-allocated memory at time of FSM start to ensure we have it later when creating child FSMs. Change-Id: Ib88a2c02c5c91f17b4ec1e9db57a06d6d66465fb

| | | | | | | | | | | If lapd_dl_flush_hist() is called after lapd_dl_exit(), dl->tx_hist has already been free'd and set to NULL. Check for this before attempting to de-reference a NULL pointer. This bug breaks OpenBSC with any E1 based BTSs using DAHDI. Change-Id: I117ba3445fa5e8097e21c11c5a6337de6ba46c7d Related: OS#1760

* fsm: Introduce default time-out handlingHarald Welte2016-06-271-8/+13
| | | | | | | | | | | If a FSM doesn't specify any timer_cb, simply terminate the FSM by default on time-out. This is a reasonable default for most cases, and avoids copy+pasting a one-line timer_cb function in every FSM. Also, even if there is a timer_cb, let it have a return value to decide if the core should terminate after return from timer_cb or not. Change-Id: I0461a9593bfb729c82b7d1d1cf9f30b1079d0212

* Revert "gsm48: move to hex TMSI representation"Holger Freyther2016-05-201-1/+2
| | | | | | | | | | | | | | | | | This is a "flag" day change. Old OpenBSC break with new libosmocore because suddenly there is the 0x in front. I am afraid we need to find a better solution here. I think we will need to create a gsm48_mi_to_string variant that takes a mode parameter to enable the TMSI mode and deprecate the old method. Right now we should not break old versions of OpenBSC.
