2015-05-25Add APN utility function to libosmogsmHarald Welte3-1/+42
The current functions are used to 'qualify' an APN from the user-supplied APN name (name identifier) towards the fully-qualified APN name which is used in the .grps DNS zone.

2015-05-06bssgp: Fix bssgp_tx_fc_bvc parameter typeJacob Erlbeck1-1/+1
Currently large values for Bmax default MS get sliced since a uint16_t is used as the type of the corresponding parameter of bssgp_tx_fc_bvc. GSM 48.018, 11.3.2 which in turn refers to 11.3.5 specifies a maximum of 6MB (0xffff * 100). This commit changes the type to uint32_t to cover the full value range. Sponsored-by: On-Waves ehf
2015-04-30bssgp: Fix call to llist_entry in fc_queue_timer_cfgJacob Erlbeck1-1/+1
Currently the DL sometimes hangs and sometimes a lot of messages (still not able to send PDU) are logged. This is caused by an invalid timer delay computation, setting msecs either to 0 or to some big value. This is due to an '&' operator at the wrong place, accessing some parts in fc instead of the first element of the list. This commit fixes that issue. Sponsored-by: On-Waves ehf
2015-04-29bssgp: Fix encoding of BVC_FLOW_CONTROLJacob Erlbeck1-5/+5
Currently all 2 byte IE of the message are transmitted in the little endian byte ordering. This commit adds htons to the encoding expressions. Sponsored-by: On-Waves ehf
2015-04-29bssgp: Fix output of the VTY 'show bssgp stats' commandJacob Erlbeck1-2/+3

2015-04-11utils: Disable the weak symbol for darwinHolger Hans Peter Freyther1-1/+5
We should consider simply removing the alias as we have had several ABI changes since introducint the alias utils.c:223:23: error: only weak aliases are supported on darwin __attribute__((weak, alias("osmo_hexdump_nospc")));
2015-04-10gprs: Add assertion for msg != NULL to bssgp_msgb_alloc (Coverity)Jacob Erlbeck1-0/+4
Currently out-of-memory is not handled by bssgp_msgb_alloc, leading to SEGV failures if msgb_alloc_headroom returns NULL. This commit adds an OSMO_ASSERT to catch this case, which improves the situation only slightly. But bssgp_msgb_alloc is used in many places without checking the return value, so just adding a conditional early NULL return would not fix the issue either. Fixes: Coverity CID 1293377 Sponsored-by: On-Waves ehf
2015-04-10msgb: Check the return value of msgb_alloc (Coverity)Jacob Erlbeck2-0/+6
In some places, the return value of msgb_alloc/msgb_alloc_headroom is not checked before it is dereferenced. This commit adds NULL checks to return with -ENOMEM from the calling functions if the alloc function has failed. Fixes: Coverity CID 1249692, 1293376 Sponsored-by: On-Waves ehf
2015-04-07ns: Log when sending fails (Coverity)Jacob Erlbeck2-0/+20
Currently the return value of the gprs_ns_tx family of functions is often ignored. This is not a serious issue, since the successful delivery of the messages is neither guaranteed nor acknowledged by the network layer anyway. Nevertheless this commit adds logging (level INFO) to gprs_ns_tx and gprs_ns_msgb_alloc. The definition of the latter has been moved from the header file to gprs_ns.c. Fixes: Coverity CID 1040678, 1040679, 1040680, 1040681, 1040682, 1040683, 1040684, 1040686, 1040687, 1040688, 1111545, 1240203, 1240204 Sponsored-by: On-Waves ehf
2015-04-07bssgp: Ensure non-NULL bctx before calling bssgp_rx_ptp (Coverity)Jacob Erlbeck1-1/+6
Currently bssgp_rx_ptp might be called with bctx being NULL, when the NS BVCI is neither BVCI_SIGNALLING nor BVCI_PTM, but the message is a BVC_RESET or it contains an BVCI IE != BVCI_SIGNALLING where the BVCI is not known. This patch ensures that bssgp_rx_ptp will only be called with a non-NULL bctx. A log message will be issued, if the bctx is NULL when this was not expected. Fixes: Coverity CID 1040674 Sponsored-by: On-Waves ehf
2015-04-07bssgp: Always expect dup != NULL in bssgp_tx_dl_ud (Coverity)Jacob Erlbeck1-25/+24
Currently the implementation of bssgp_tx_dl_ud conditionally adds some optional IE if dup != NULL. Later on is dereferences dup to access qos_profile and fc, but this without checking dup in advance. This may lead to an segmentation violation fault. This commit changes the value range of the function to only accept dup != NULL. An assertion will fail otherwise. All other explicit checks for non-NULL are removed. Fixes: Coverity CID 1040673 Sponsored-by: On-Waves ehf
2015-04-05ctrl: Avoid accessing cmd_desc->command out of boundsHolger Hans Peter Freyther1-1/+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.

2015-03-18libctrl: Include config.h so we can include netinet/tcp.hHolger Hans Peter Freyther1-0/+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... Include config.h so we can see if there is a tcp.h and then include it.

2015-03-18bssgp: Handle BSSGP STATUS messagesJacob Erlbeck1-16/+62
Currently incoming BSSGP STATUS messages are just logged and no other action is taken. This makes it impossible for higher layers to react to failures which are indicated by corresponding STATUS messages unless a timeout is triggered as a result of that failure later on. This commit adds a bssgp_rx_status() function and calls it on incoming STATUS messages. That function logs a message, increments the new BSSGP_CTR_STATUS counter if the bctx context exists and invokes an NM_STATUS status indication. The latter will allow the application to handle failures immediately. Since all STATUS messages should be handled, the function is already called in bssgp_rcvmsg and the message is no longer handled in (and will not reach) bssgp_rx_sign and bssgp_rx_ptp. Ticket: OW#1414 Sponsored-by: On-Waves ehf
2015-03-18bssgp: Don't reply with STATUS when receiving a PtP STATUS messageJacob Erlbeck1-0/+2
Currently each incoming PtP BSSGP STATUS message is handled as 'not yet implemented' and a BSSGP STATUS message (cause BSSGP_CAUSE_PROTO_ERR_UNSPEC) is sent back to the peer. This will cause endless messages loops if both peers use this BSSGP stack implementation. This does not apply to signalling messages. This commit changes the implementation of bssgp_rx_ptp() to just do logging in this case. Sponsored-by: On-Waves ehf
2015-03-18logging: Implement subsecond resolution of extended timestampsJacob Erlbeck1-4/+7
Currently when using 'logging print extended-timestamp 1', the subsecond part (milliseconds) of the printed timestamp is always 0. This makes it difficult to correlate log entries with PCAP file entries if there are many of them per second. This patch changes _output in logging.c to use gettimeofday() instead of time() when extended timestamps are enabled and replaces the '000' by the milliseconds computed from tv_usec.

2015-01-01Supplementary Services (de)activation, interrogation addedTobias Engel2-25/+102
These patches enhance the Supplementary Service (SS) processing from only being able to handle USSD to other SS, specifically activation, deactivation and interrogation of those SS. Registration is not yet implemented. include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed values for SS. Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI stability.

2014-12-28log: "logging level everything" is a badly named option.Holger Hans Peter Freyther1-1/+1
We tried to fix it but it isn't that easy. The original fix was cd6ed82d1ff48f47ad9e33e6322df62896a76ed5 but we had to revert it as "everything" is present/used in existing config files. If we ever change the ABI we can make everything be something that is > 0. For now use a wording that makes it obvious that people should not use "everything".

2014-12-22ipa: Return -errno instead of -1 in ipa_sendJacob Erlbeck1-1/+1
Currently, the ipa_send function returns -1 in one execution branch to indicate an error and -EIO in another. This is not consistent and can lead to a misinterpretation of the error code, since -1 is -EPERM and in general, EPERM is not returned by write(2). This patch changes the return code to -errno instead of -1 for the case that write(2) fails for same reason. So -rc is always a sensible error value if there is a failure. Sponsored-by: On-Waves ehf

2014-12-05logging: Make it possible to print category/subsys and timestampsHolger Hans Peter Freyther2-4/+95
We want to see from which category/subsystem a certain log message is coming from and use a different timestamp format as well. Add two new bitfields. This doesn't change the size of the structure and on 32bit we still have 27bits left. The extended timestamp will take preference over the current and default timestamp format. Fixes: SYS#602
