* logging vty: add VTY transcript testNeels Hofmeyr2018-09-121-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | I am setting out to refactor various details about logging. To show the effect, I am first adding this new test to illustrate the exact effects on the various osmo programs. Add logging_vty_test.c as a standalone program that simply defines a few logging categories and opens a telnet vty to play with. Add logging_vty_test.vty, as an osmo_verify_transcript_vty.py test script. Add --enable-external-tests to configure.ac, to enable running logging_vty_test.vty during 'make check'. Also allow running 'make vty-test' without the need to first configure with --enable-external-tests (a flexibility I've missed many times over in the other osmo source trees). Add a Makefile.am stub for external CTRL tests, basically a copy-paste from osmo-msc.git. I doubt that libosmocore will get python driven CTRL interface testing any time soon, but if so we will know to not run it concurrently. Change-Id: I948e832a33131f8eab98651d6010ceb0ccbc9a9c
* fix tests linking: don't use system installed libsNeels Hofmeyr2018-09-111-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not link against the system-wide installed libosmo* libs when building the regression test programs. Always use the locally built ones. Linking some libosmo libraries causes libtool to pull in other libosmo libs even though they were not explicitly named. For example, ctrl_test explicitly links libosmoctrl, but this also has dependencies to libosmovty and libosmogsm: ldd src/ctrl/.libs/libosmoctrl.so | grep osmo libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f26c26d4000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f26c22bb000) libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f26c2171000) If we omit explicit LDADD of these dependencies in the Makefile.am, libtool will take the first canonical place to find them, which may just be the already installed older versions of the same libs, which may or may not be compatible with the current build. In any case, it is never intended to link installed libs. All library dependencies are listed by this quick script: cd libosmocore for l in $(find . -name "*.so") ; do echo; echo "$l"; ldd $l | grep libosmo; done ./.libs/libosmocore.so ./coding/.libs/libosmocoding.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f25fc3c2000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f25fbfa9000) libosmocodec.so.0 => /usr/local/lib/libosmocodec.so.0 (0x00007f25fbf9b000) ./codec/.libs/libosmocodec.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007fb4c900d000) ./ctrl/.libs/libosmoctrl.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f5df5129000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f5df4d10000) libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f5df4bc6000) ./gb/.libs/libosmogb.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f788e536000) libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f788e3ec000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f788dfd3000) ./vty/.libs/libosmovty.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f3b7ed21000) ./gsm/.libs/libosmogsm.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007fc69472e000) ./sim/.libs/libosmosim.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f2f6412d000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f2f63d14000) Add all explicit linking of all required library dependencies in all regression test programs, as shown by above listing. Example for reproducing a problem: In libosmocore.a, introduce a new function, and call that from libosmovty code. For example, I made loglevel_strs non-static in logging.c, and used that in logging_vty.c. Build and install this in a place where libtool can find it. Then go back to before this change and rebuild. You will see that linking ctrl_test (before this patch) then complains about libosmovty requiring the loglevel_strs symbol which it cannot find in libosmocore.so.

* fix vty regression: empty parent nodeNeels Hofmeyr2017-09-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The recent exit-by-indent patch breaks a VTY case where a node is entered but directly followed by a sibling or ancestor without listing any child nodes. Regression introduced by I24cbb3f6de111f2d31110c3c484c066f1153aac9. An example is a common usage in osmo-bts, where 'phy N' / 'instance N' is a parent node that is commonly left empty: phy 0 instance 0 bts 0 band 1800 Before this patch, this case produces the error: There is no such command. Error occurred during reading the below line: bts 0 Fix indentation parsing logic in command.c to accomodate this case. Add a unit test for empty parent node.

* VTY: implicit node exit by de-indenting, not parent lookupNeels Hofmeyr2017-09-191-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note: This will break users' config files if they do not use consistent indenting. (see below for a definition of "consistent".) When reading VTY commands from a file, use indenting as means to implicitly exit child nodes. Do not look for commands in the parent node implicitly. The VTY so far implies 'exit' commands if a VTY line cannot be parsed on the current node, but succeeds on the parent node. That is the mechanism by which our VTY config files do not need 'exit' at the end of each child node. We've hit problems with this in the following scenarios, which will show improved user experience after this patch: *) When both a parent and its child node have commands with identical names: cs7 instace 0 point-code 1.2.3 sccp-address osmo-msc point-code 0.0.1 If I put the parent's command below the child, it is still interpreted in the context of the child node: cs7 instace 0 sccp-address osmo-msc point-code 0.0.1 point-code 1.2.3 Though the indenting lets me assume I am setting the cs7 instance's global PC to 1.2.3, I'm actually overwriting osmo-msc's PC with 1.2.3 and discarding the 0.0.1. *) When a software change moves a VTY command from a child to a parent. Say 'timezone' moved from 'bts' to 'network' level: network timezone 1 2 Say a user still has an old config file with 'timezone' on the child level: network bts 0 timezone 1 2 trx 0 The user would expect an error message that 'timezone' is invalid on the 'bts' level. Instead, the VTY finds the parent node's 'timezone', steps out of 'bts' to the 'network' level, and instead says that the 'trx' command does not exist. Format: Consistent means that two adjacent indenting lines have the exact same indenting characters for the common length: Weird mix if you ask me, but correct and consistent: ROOT <space>PARENT <space><tab><space>CHILD <space><tab><space><tab><tab>GRANDCHILD <space><tab><space><tab><tab>GRANDCHILD2 <space>SIBLING Inconsistent: ROOT <space>PARENT <tab><space>CHILD <space><space><tab>GRANDCHILD <space><tab><tab>GRANDCHILD2 <tab>SIBLING Also, when going back to a parent level, the exact same indenting must be used as before in that node: Incorrect: ROOT <tab>PARENT <tab><tab><tab>CHILD <tab><tab>SIBLING As not really intended side effect, it is also permitted to indent the entire file starting from the root level. We could guard against it but there's no harm: Correct and consistent: <tab>ROOT <tab><tab>PARENT <tab><tab><tab><tab>CHILD <tab><tab>SIBLING Implementation: Track parent nodes state: whenever a command enters a child node, push a parent node onto an llist to remember the exact indentation characters used for that level. As soon as the first line on a child node is parsed, remember this new indentation (which must have a longer strlen() than its parent level) to apply to all remaining child siblings and grandchildren. If the amount of spaces that indent a following VTY command are less than this expected indentation, call vty_go_parent() until it matches up. At any level, if the common length of indentation characters mismatch, abort parsing in error. Transitions to child node are spread across VTY implementations and are hard to change. But transitions to the parent node are all handled by vty_go_parent(). By popping a parent from the list of parents in vty_go_parent(), we can also detect that a command has changed the node without changing the parent, hence it must have stepped into a child node, and we can push a parent frame. The behavior on the interactive telnet VTY remains unchanged. Change-Id: I24cbb3f6de111f2d31110c3c484c066f1153aac9

* libosmocoding: migrate transcoding routines from OsmoBTSVadim Yanitskiy2017-03-071-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | There are some projects, such as GR-GSM and OsmocomBB, which would benefit from using one shared implementation of GSM 05.03 code.

* wqueue: Reject messges if queue is considered fullHolger Hans Peter Freyther2016-12-091-2/+6
| | | | | | | | | | | | | | | | | | The write queue was always meant to not queue more than the max_length messages but the implementation never rejected a message. Begin to log and enforce the queue size limit, add a testcase to verify the code and initialize except_cb as part of a fix for that new test case. Real applications might now run into the queue limit and drop messages where they just queued them before. It is unfortunate but I still think it is good to implement the routine as it was intended. We need to review osmo_wqueue_enqueue once more to see that no msgb is leaked. Change-Id: I1e6aef30f3e73d4bcf2967bc49f0783aa65395ae
* build: make check: disable sim_test when built with --disable-pcscNeels Hofmeyr2016-11-161-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Numerous issues caused sim_test to be attempted even though libosmosim was not built: In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported. Furthermore in configure.ac, no value 'yes'/'no' was assigned to the ENABLE_PCSC variable, only to the enable_pcsc value. In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have no effect, regardless (not even when using a variable that should be defined accurately). So fix with these steps, similarly to how we do it in openbsc: In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'. Export the same using AC_SUBST(). Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add atlocal to AC_OUTPUT and distclean). Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to indicate skipping the test if enable_sim_test isn't 'yes'. Change-Id: I9e8740c7d2dfbd272e22fee85972ef3fda7184a8

* import gprs_gsup_message.[ch] from openbsc as gsup.[ch]Harald Welte2016-05-061-2/+5
| | | | | | | Move those routines from OpenBSC to libosmogsm, so they can be re-used from other programs. I think it was a mistake to add them only inside the openbsc repository in the first place. We need to pay more attention to this in the future.
* tlv: Import osmo_shift_* and osmo_match_shift_* from openbscHarald Welte2016-05-051-2/+5
| | | | | These routines have nothing to do with specifically the BSC, so import them to the TLV parser we keep in libosmogsm.
* Add code generator for convolutional codesMax Suraev msuraev@sysmocom.de2016-04-291-1/+1
| | | | | | | | | | | | | | | | Add python utility to generate .c code with convolutional encoder/decoder based on polynomial description of the code. If argument given it'll be interpreted as intended output directory, otherwise current working directory is used. Codes for *CCH, CS2/3 and TCH/AFS are generated. Corresponding manual implementations are removed from tests. This introduce build-time dependency on python. The main work for this patch was generously contributed by Sylvain Munaut. Fixes:
