2016-03-1504.08: switch to r99 msg type bitmasks by defaultNeels Hofmeyr1-1/+1
[hfreyther: Separated from the previous patch to allow an easy revert]
2016-03-1504.08: add inline funcs for pdisc + msg type bitmasksNeels Hofmeyr2-2/+58
Add inline functions for both release <= 98 and release >= 99 as well as a default define. Use the release 98 by default since the current code base uses the r98 bitmasks. These inline functions relieve callers of the decision on masking bits of the protocol discriminator and message type octets. Also add a define for the protocol discriminator extension to one octet length (GSM48_PDISC_EXTEND). Apply new pdisc function in gsm0480.c. [hfreyther: Make the hdr param const]
2016-03-11Add helper function to convert numerical BSSGP PDU type to stringMax2-0/+47
2016-03-11Add support for SI2quater messagesMax1-0/+7
Add basic data structure for System information Type 2quater.
2016-03-11rename osim_file_find_* to osim_file_desc_find_*Harald Welte3-7/+9
they return an osim_file_desc, and not an osim_file, so fix the naming
2016-03-11sim: Add osim_file_find_{fid,sfid}() functionsHarald Welte2-0/+31
We don't always want to look-up by name, but the latter is the only implemented 'find' function so far. Let's change that.
2016-03-11merge_doc.xsl: Don't copy the 'descripiton' element of commandsHarald Welte1-1/+3
If a vty_additions.xml file contained a <description> element inside a command> element, then the description was copied twice (once during the <node> copy, and once during the <command> copy). Let's avoid one of the two copies.
2016-03-05debian: Make sure that libtalloc-dev is installedHolger Hans Peter Freyther1-1/+1
This way libosmo-abis, libosmo-sccp, openggsn, openbsc does not need to install it.
2016-02-29logging: Remove unused variable after recent changesHolger Hans Peter Freyther1-1/+0
The variable is not used anymore as the decision is done in the newly added check_log_to_target method.
2016-02-29Merge branch 'sysmocom/shared/log-speed'Holger Hans Peter Freyther4-34/+106
2016-02-29logging: Move the filter check up as wellHolger Hans Peter Freyther3-18/+24
There doesn't seem to be a reason not to check the filter. Update and extend the test. Currently the filter function will be called once for the log check and once for the output of it.
2016-02-29logging: Remove some code duplicationHolger Hans Peter Freyther1-37/+37
Extract the mapping of the subsystem number and the checking for the loglevel to a inline method that is shared between the new and old.
2016-02-29log/test: Extend test case for log_check_levelJacob Erlbeck2-1/+11
This commit adds OSMO_ASSERTs for mandatory conditions related to log_check_level, and fprintfs for optional conditions, since it is always safe for log_check_level to return != 0. Sponsored-by: On-Waves ehf
2016-02-29log: Add conditional logging based on log_check_levelJacob Erlbeck1-4/+20
Currently the LOGP/DEBUGP arguments are always evaluated even if no logging will happen at all. This can be expensive, for instance if hexdumps or pretty printed object names are generated. This causes high base load especially on embedded devices and is a major part of CPU usage e.g. of the osmo-pcu. This commit uses the log_check_level function to avoid the evaluation of the parameters if it is known in advance, that no logging entry will be generated. Sponsored-by: On-Waves ehf
2016-02-29log: Add log_check_level functionJacob Erlbeck2-0/+40
This commit adds this predicate function which can be used to avoid the execution of code if a certain log level is not enabled. The function will only return 0 (false), if it is sure that a logging call for the same facility and level will not produce any output. This safety criterion shall ensure, that no logging output is lost due to the use of this predicate as a guard. On the other hand, even if the predicate returns != 0 (true), no logging output might get generated by a similar logging command. Note that the current implementation is not focussed on performance, which could be improved by using a lookup table instead of iterating through every target. Sponsored-by: On-Waves ehf

2016-02-25Add byte printing macrosMax2-12/+22
It's sometimes handy for debugging to be able to immediately see which bits are set in a given byte. Generalize macro used for that in bitvec tests and make it available for the rest of the library.
2016-02-25vty: add ctrl section for Control interface bind addressNeels Hofmeyr5-2/+104
This may seem like overkill for a mere const char * config item, but it makes the Control interface VTY commands reusable in any main() scope (inspired by libosmo-abis' VTY config). Add API functions ctrl_vty_init() and ctrl_vty_get_bind_addr(), in new files src/ctrl/control_vty.c and include/osmocom/ctrl/control_vty.h, compiled and/or installed dependent on ENABLE_VTY. Using these functions allows configuring a static const char* with the VTY commands ctrl bind A.B.C.D which callers shall subsequently use to bind the Control interface to a specific local interface address, by passing the return value of ctrl_vty_get_bind_addr() to control_interface_setup(). Add CTRL_NODE to enum node_type, "eating" RESERVED4_NODE to heed that comment on avoiding ABI changes.
2016-02-25add ctrl_interface_setup_dynip() for bind addressNeels Hofmeyr2-1/+13
Make the ctrl interface bind address configurable, so that it may be made available on other addresses than 127.0.0.1. The specific aim is to allow running multiple osmo-nitbs alongside each other (commits in openbsc follow).
2016-02-25vty: add bind command for telnet vty lineNeels Hofmeyr2-0/+31
Add VTY command line vty bind A.B.C.D The command merely stores the configured IP-address, which can then be used by the calling main program to set the telnet port of the VTY line. (Commits in openbsc and osmo-iuh will follow up on this.) Add function vty_get_bind_addr() to publish the address in the vty.h API. Add static vty_bind_addr to store. For allocation/freeing reasons, a NULL address defaults to 127.0.0.1. BTW, I decided against allowing keywords 'any' and 'localhost' in place of an actual IP address to make sure a written config is always identical to the parsed config.
2016-02-22Extend L1SAP PH-DATA with presence informationMax2-0/+12
Previously the presence of header and data blocks were communicated in-band which decreases code readability and makes it unnecessary hard to add support for new hardware. Note: OsmoBTS have to be modified to take advantage of extended ph_data_param structure.
2016-02-22gb: Add bssgp_msgb_copy functionJacob Erlbeck5-0/+70
This function originates from openbsc/src/gprs but is just specific to BSSGP/Gb on the same level like bssgp_msgb_alloc. This commit puts the former gprs_msgb_copy function beside bssgp_msgb_alloc. Renamed function: gprs_msgb_copy -> bssgp_msgb_copy Sponsored-by: On-Waves ehf
2016-02-18bitvec: Untested speculative UBAN fix for the new routineHolger Hans Peter Freyther1-1/+1
int << 31 does not seem to be defined, let's try to make it an unsigned variable and see if that is pleasing the system. Fixes: bitvec.c:219:15: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
2016-02-18Add T4 bit map compression routinesMax9-3/+631
Add bit map encoder and decoder functions: decoder is fully functional while encoder is good enough for testing - no backtracking to find the best possible compression is implemented. If somebody is willing to implement MS side of EDGE than this has to be expanded. Add corresponding tests. N. B: the encoding is implemented according to ETSI TS 44.060 which is slightly different from T4 used for fax according to CCITT G31D (RFC 804).

2016-01-30bivec: Fix the output of the testcaseHolger Hans Peter Freyther2-12/+16
osmo_hexdump_nospc/osmo_hexdump is an old school C routine with a static internal array. This means that printf will most likely one of the two strings twice. For Linux/glibc this is the first string (for whatever reason?) and for FreeBSD it is the last call of the osmo_hexdump_nospc. We could have noticed by both strings being of the same length besides the different length input. The second issue is that we cast a hexstring to uint8_t and dump the string as hex. So the two strings should not match at all. Fix it by printing the hex string as plain hex and separating the two printf calls. Update the test output.
2016-01-30bitvec: Test and fix regression for C++->C conversionHolger Hans Peter Freyther4-11/+42
bitvec_read_field/bitvec_write_field in the PCU used a C++ reference and when porting to C it was decided to pass the parameter by value and this lost the "back propagation" of the new index. Change the parameter to be an in/out parameter and this way do not have a silent semantic break in the osmo-pcu (where we copy the reference in csn.1 by value) and have a true compile failure. Add Max's simple test for bitvec_unhex function leaving the checking of bitvec_read_field and the side effect in the datastructure about the number of bits still open.

2016-01-26Add bitvec-related functions from Osmo-PCUMax2-0/+104
Allocation, pack/unpack, field access and helper routines used extensively by Osmo-PCU. Whenever memory allocation happens, alocator context is passed explicitly by caller.
2015-11-09test: Fix compiler warnings on 64bit systemsHolger Hans Peter Freyther6-17/+18
Use %td to print ptrdiff_t use %zu to print size_t, include time.h on FreeBSD. Some more compiler warnings are left but they require more thinking.

2015-11-09vty: Use NULL to have a null pointer instead of '\0'Holger Hans Peter Freyther1-3/+3
'\0' gets translated to zero but the argument to vector_set is a pointer and it gets converted to a pointer. vty.c:985:21: warning: expression which evaluates to zero treated as a null pointer constant of type 'void *' [-Wnon-literal-null-conversion] vector_set(vline, '\0'); ^~~~ vty.c:1095:21: warning: expression which evaluates to zero treated as a null pointer constant of type 'void *' [-Wnon-literal-null-conversion] vector_set(vline, '\0'); ^~~~ vty.c:1097:21: warning: expression which evaluates to zero treated as a null pointer constant of type 'void *' [-Wnon-literal-null-conversion] vector_set(vline, '\0'); ^~~~

2016-01-22bitvec: Fix unaligned memory access in osmo_revbytebits_bufMax1-2/+1
The undefined behavior sanitizer found the 32bit load from an unaligned memory address. This will cause an exception on ARMv5te and a manual fix-up. [hfreyther: On armv6, x86 the usage of memcpy leads to shorter amount of instructions but on armv5te the memcpy is not expanded leading to a branch. Use the version of max until we have the time to benchmark it] Sponsored-by: On-Waves ehf
2016-01-22Fix sporadic out-of-bounds errorMax1-13/+21
This code dealing with bit shifting sometimes gets 1 byte beyond array boundary while calculating index. This is now explicitly checked and prevented. Ticket: OW#1198 Sponsored-by: On-Waves ehf
2016-01-21kasumi: Fix build with gcc5 that changed behavior of inlineHolger Hans Peter Freyther1-1/+1
GCC 5 has changed inline semantics (https://gcc.gnu.org/gcc-5/porting_to.html) and apparently that now fails to link.
2016-01-18debian: Avoid linking with -Bsymbolic-functionsHolger Hans Peter Freyther1-0/+3
Our tests want to be able to change symbols from the library and even by using --wrap=XYZ it is not possible right now. One option would be to use static linking but that is not always enabled, the other is to skip tests on Ubuntu and the third one is to disable that linking mode. This means that the dynamic linker needs to spend some more time but we do spend this time on all other distros and this looks acceptable.

Include a test for msgb_trim. Sponsored-by: On-Waves ehf
2016-01-15msgb: Assert len >= 0 in msgb_trimJacob Erlbeck1-0/+2
Currently msgb_trim only checks for len > data_len and returns -1 in that case, allowing the caller to fix it somehow. Using a negative length will always lead to a corrupt msgb, but this is not being checked. This commit adds a check for len < 0 and a conditional call to MSGB_ABORT. Sponsored-by: On-Waves ehf

2016-01-15msgb/test: Add functions to catch and check exceptionsJacob Erlbeck2-1/+32
Currently the msgb error handling cannot be fully tested, since in many cases osmo_panic will be called. This will in turn call abort(). Using an osmo_panic_handler that just returns will not help, since many msgb functions rely on MSGB_ABORT to not return at all. This commit uses an alternative osmo_panic_raise handler that just calls longjmp to return to the test function. Since some of this activity is logged to stderr where the strings may contain variable parts like pointer addresses, stderr checking is disabled in testsuite.at. Sponsored-by: On-Waves ehf
2016-01-15msgb/test: Add test for msgb message buffersJacob Erlbeck4-2/+136

2016-01-15bitvec: Add get/set byte sequencesJacob Erlbeck6-2/+162
The new functions bitvec_get_bytes and bitvec_set_bytes copy byte sequences from bitvecs to uint8_t arrays and vice versa. While the bytes in the bitvecs do not need to be aligned, the uint8_t arrays always are. In case the bytes in the bitvec are aligned, the implementation uses memcpy. Note that the implementation like the other existing functions assume MSB first encoding. [hfreyther: Squash the comment fix into this commit as well] Sponsored-by: On-Waves ehf
2016-01-15gsm: Add APN conversion functionsJacob Erlbeck7-3/+216
These functions are currently part of openbsc but also needed by other projects. The function have been renamed as follows: gprs_apn_to_str -> osmo_apn_to_str gprs_str_to_apn -> osmo_apn_from_str Sponsored-by: On-Waves ehf
