* control_cmd.c: Fix unsigned comparison against < 0Pau Espin Pedrol2017-06-231-1/+1
| | | | | | | | Fixes following warning: control_cmd.c:294:16: warning: comparison of unsigned enum expression < 0 is always false [-Wtautological-compare] if (cmd->type < 0 || cmd->type == CTRL_TYPE_UNKNOWN) { Change-Id: I3df8a4f646222337927d9e3cac6d09a8a05cb20c
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-234-6/+11
| | | | | | | | | | | | | | | | | Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-232-7/+7
| | | | | | | | | | Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
* Simplify ctrl cmd lookupMax2017-05-082-32/+25
| | | | | | | Replace if-else ladder & gotos with single switch statement & explicit return to make reading code easier. Change-Id: Ida1b389b571c60c26813cd29e61b3e4423c5df0f
* Fix broken ctrl commandsMax2017-05-031-1/+2
| | | | | | | | | | | Recent changes to libosmoctrl resulted in ctrl comands being broken because local lookup helper returned incorrect value for ROOT_NODE. Note: although this commit seems to fix it for me, I'm still not sure how the logic behind lookup function return values work. Would be nice to get it documented.

* control_if: Don't use magic number '5' when allocating vectorHarald Welte2017-04-271-1/+1
| | | | | | We have a proper constant for this (_LAST_CTRL_NODE), so let's use it. Change-Id: I46275e644166156cb665da70d2964008f1c6cd88
* control_if: Add control interface commands for FSMsHarald Welte2017-04-273-1/+180
| | | | | | | | | This allows programmatic access to introspection of FSM instances, which is quite handy from e.g. external test cases: Send a message to the code, then use the CTRL interface to check if that message has triggered the right kind of state transition. Change-Id: I0f80340ee9c61c88962fdd6764a6098a844d0d1e
* control_if: Add helper function for 'local execution' of control commandHarald Welte2017-04-271-0/+28
| | | | | | | | Sometimes (particularly when testing), we may want to parse+execute an arbitrary control command simply form a string buffer, rather than from a msgb. Let's add a helper for that. Change-Id: Iaca748e0d942bb2a1ee7c2776b37485e1439eb0c
* control_if: Add API to initialize control interface without TCP port bindHarald Welte2017-04-261-27/+63
| | | | | | | When executing test cases, we don't want to bind to a local TCP port, as we cannot make assumptions as to which ports are actually free. Change-Id: I5717f9dd92d1f143f069cecd4b4c8ba3d03b25f8
* ctrl: Allow installation of additional node lookup helpersHarald Welte2017-04-261-0/+41
| | | | | | | | | | | | The existing code assumes that the main application knows about all control command nodes and can thus present one lookup function. As libraries are getting their own control interface handling, this is too restrictive, and we need a way how library code can dynamically register more node lookup helpers. We can now do this by means of a ctrl_lookup_register() function. Change-Id: Ib69908d1c57f5bb721d5496e3b4a5258fca450e3

* ctrl_type_vals: explicitly terminateNeels Hofmeyr2017-03-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't use CTRL_TYPE_UNKNOWN as value_string[] terminator, use an explicit, more obvious { 0, NULL } termination. Set an explicit string for CTRL_TYPE_UNKNOWN. No other value_string[]s to date have such a "hidden" terminator. BTW, a { 0, "string" } item is not a terminator, only { 0, NULL } is, so we can set a string for CTRL_TYPE_UNKNOWN == 0. Also, having a string value for CTRL_TYPE_UNKNOWN is not harmful because all code paths explicitly check for the CTRL_TYPE_*s that are valid. Adjust the test expectation. From the ctrl_type_vals enum, remove the = 0, because it is implicitly 0 anyway. One motivation to press this fixup: I am trying to add a script that checks whether all value_string[]s are terminated to our jenkins jobs, and to find that this one is terminated, it would need to interpret the CTRL_TYPE_UNKNOWN constant, which would make things far more complex. At this point, all of the value_string[]s have an explicit termination, and I would like to enforce this from now on -- for readable code and to not spend more time on the validator. The patch adding ctrl_type_vals (Icd4e96dd9f00876cb70b43cfcf42ab4f10311b28) was accepted by another reviewer before I could reconfirm my -1, so this is a fixup to enable the termination checking script patches.

* Handle replies in ctrl_cmd_handle()Max2017-03-011-0/+17
| | | | | | | | | | | | Previously *_REPLY and ERROR messages were not explicitly handled which would lead to sending error in response to them which in turn would prompt other party to send error as well which would result in infinite cycle.

* ctrl_cmd_parse: Make coverity FORWARD_NULL happyHarald Welte2016-11-261-0/+1
| | | | | | | | | | | | The 'strtok_r' function requires passing a NULL as the first parameter on subsequent calls in order to ensure the code picks up where it left off on a previous call. However, Coverity doesn't quite realize this and points out that if a NULL was passed in as the third argument it would result in a possible NULL deref because the strtok_r function will assign the third argument to the first in the call is NULL.

* vty: add ctrl section for Control interface bind addressNeels Hofmeyr2016-02-252-0/+92
| | | | | | | | | | | | | | | | | | | | | | | 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.
* add ctrl_interface_setup_dynip() for bind addressNeels Hofmeyr2016-02-251-1/+9
| | | | | | 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).
* remove our internal copy of talloc, use system libtallocHarald Welte2015-12-051-2/+2
| | | | | | | Shipping our own private copy of talloc was a good idea in 2008, when it was not readily available on most target platforms. Today, the situation is quite different, as it is a standard library on major Linux distributions.
* ctrl: Avoid accessing cmd_desc->command out of boundsHolger Hans Peter Freyther2015-04-051-1/+1
| | | | | | | | We check that the amount of commands is not more than we have but we don't check it the other way. It appears that the vector is allowed to be bigger than the amount of commands. So we match a prefix of a longer command depending on the installation order.
* libctrl: Include config.h so we can include netinet/tcp.hHolger Hans Peter Freyther2015-03-181-0/+2
| | | | | | | | | | In e15ac060e7ae78d4c3569d7fc9071bcf49807e05 we tried to fix the nuttx build but we never included "netinet/tcp.h" after it and the compiler warned about the unused "on" parameter which we didn't notice because of the other warnings...

* libctrl: Add support for 'deferred control commands'Harald Welte2014-08-242-0/+77
| | | | | | | | | | | | | | Sometimes a control interface command cannot be processed and responded immediately, but we need to process it asynchronously. In order to support this, we introduce the 'ctrl_cmd_def', which represents such a deferred command. It is created by the service implementing the command using ctrl_cmd_def_make(), and a response is later sent using ctrl_cmd_def_send(). ctrl_cmd_def_is_zombie() must be called to handle the case where the control connection has disconnected/died between receiving the command and sending the response.
