2018-10-08vty: make 'show calls summary' more userfriendlyOliver Smith1-29/+26
Display a table with one row per call (instead of two lines per call), and display the phone numbers of the people making the calls instead of internal IDs. This should make the VTY command friendlier for end users, especially if they have bigger networks. There is still the 'show calls' command with all the verbose output. Example output: OsmoSIPcon> show calls summary No active calls. OsmoSIPcon> show calls summary ID From To State ----- -------------------------------- -------------------------------- ---------- 5001 101 100 PROCEEDING OsmoSIPcon> show calls summary ID From To State ----- -------------------------------- -------------------------------- ---------- 5001 101 100 CONNECTED Relates: OS#1680 Change-Id: I2092d58d80a34e6083f618593b92bb9e838aa906

2018-08-31Add SIP <-> MNCC Cause MapKeith1-0/+88
Implements a cause_map, mapping the SIP status codes to GSM48_CC_CAUSE_* that are defined in libosmocore. The map at the same time implements the Q.850 cause texts that are subsequently used in the SIP Reason: header. Implements two functions cause2status() and status2cause() to read the map and return the the mapped status. The mapping mostly follows the implemention in the LCR program, so that any implementation relying on that mapping should continue to work as expected with osmo-sip-connector.

2018-05-28Add Cause to DISCONNECT and RELEASE RequestsKeith1-7/+12
GSM 04.08 10.5.4.11 (Table 10.85) states: Coding standards other than the standard defined for the GSM PLMNS shall not be used if the cause can be represented with the GSM standardized coding. This patch adds cause coding GSM PLMS (3) and sets cause location to "public network serving the local user" (2) This prevents UE that pay attention to this from treating all call termination as an error and paves the way to adding correct cause mapping from Table 10.86 Also replaces use of magic numbers with enum constants.

2018-04-15sip: Register log callback function with sofia-sipHarald Welte4-1/+33
sofia-sip allows applications to register a log backend function which will be called every time the library wants to log something. We register such a call-back and make it log using the libosmocore logging framework. The problem is that sofia-sip has its own log level management, and by the time the message hits libosmocore, we don't know which log level we shall use :( Change-Id: Ib269b6b50f9d79bbd13acc43a626834921f05edb Related: OS#3105

So far the remote_port has never been used. sofia-sip did the right thing and put the port into the "Contact" and the rport option for the via.

2017-03-08evpoll: Add workaround for usage of IP_RECVERR in sofia-sipHolger Hans Peter Freyther1-1/+1
We are using glib to benefit from the sofia-sip-glib eventloop integration and set a poll func (evpoll) to be called by glib to integrate with the rest of libosmocore. Sofia-sip will use IP_RECVERR to enable error reporting on the socket and then sets SU_WAIT_ERR (mapped to POLLERR if not using kqueue) in the internal events flag of the socket. This will be registered with a su_wait (mapped to struct pollfd) and then glib will be called with g_source_add_poll. At this point the the fd->events will still have the POLLERR bit set. Before glib is calling its internal poll routine or our one it will copy all registered fd into an array and mask the events flags: /* In direct contradiction to the Unix98 spec, IRIX runs into * difficulty if you pass in POLLERR, POLLHUP or POLLNVAL * flags in the events field of the pollfd while it should * just ignoring them. So we mask them out here. */ events = pollrec->fd->events & ~(G_IO_ERR|G_IO_HUP|G_IO_NVAL); This leads to the POLLERR flag never been set in the revents of the struct poll_fd and as such we never put them in the exceptionset and as such: static int tport_base_wakeup(tport_t *self, int events) { int error = 0; if (events & SU_WAIT_ERR) error = tport_error_event(self); tport_base_wakeup will never call tport_error_event. And the error will be stuck in the socket data forever and recvmsg will return a zero length packet. And this will repeat until the end of time. As a first hack I mapped SU_WAIT_ERR to POLLPRI but when using select the Linux kernel will not put the socket error into the except queue unless the sockopt SOCK_SELECT_ERR_QUEUE is used. One option is to use poll and then map the select requirements to poll. Right now I just signal POLLERR as well to trigger tport_error_event. This will result in extra syscalls for each received UDP message right now. Change-Id: I5bec4a7b70f421ab670e649e5bc1ea6faf59707c
2017-03-06mncc: Fix use after free on mncc socket disconnectionHolger Hans Peter Freyther1-5/+12
