* VTY: implicit node exit by de-indenting, not parent lookupNeels Hofmeyr2017-09-192-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-239-15/+22
| | | | | | | | | | | | | | | | | 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).

* vty: Make a reservation for the osmo-sip-connectorHolger Hans Peter Freyther2016-03-311-0/+1
| | | | | The osmo-sip-connector is a new application and is a MNCC to SIP bridge. It is not implementing transcoding or RTP proxying at all.
* vty: add ctrl section for Control interface bind addressNeels Hofmeyr2016-02-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.
* vty: add bind command for telnet vty lineNeels Hofmeyr2016-02-251-0/+3
| | | | | | | | | | | | | | | | | | | | 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.

* stats/vty: Add selective show stats commandJacob Erlbeck2015-08-221-0/+2
| | | | | | | | | | | | | | | | Currently there is only the 'show stats' command which shows all counter and stat_item values. This can lead to many lines of output if there are per-subscriber rate counters. The new command added by this commit allows it to only show groups of a certain level (class_id), similar to the 'level' configuration command for stats reporter. The new command is show stats level (global|peer|subscriber) Sponsored-by: On-Waves ehf

* vty: Add reserved nodes to enum node_typeJacob Erlbeck2015-11-021-0/+9
| | | | | | | | | | | | | Currently every time a node is added to enum node_type, this constitutes an ABI change, since _LAST_OSMOVTY_NODE will get incremented accordingly. In this case, every project that adds new node type based on that value will have to be recompiled. This commit adds 4 spare node type values, which can be replaced one-by-one by new real types until they are exhausted to avoid this kind of ABI change. Sponsored-by: On-Waves ehf

The following vty commands are added to the config node: stats reporter statsd Create/Modify a statsd reporter no stats reporter statsd Remove a statsd reporter To actually configure a reporter, the config-stats node is entered when the "stats reporter" command has succeeded.

* vty: Make vty_event dispatch signals and use it in the testcaseHolger Hans Peter Freyther2013-10-101-0/+14
| | | | | | | | | The testcase didn't work on Ubuntu 12.04 because vty_create will directly call vty_event (e.g. not through the plt). This means that the approach to override vty_event in the testcase failed. Use the signal interface of libosmocore and make the testcase use it. The signals can be generally useful as well.
