* add identifier sanitation for setting FSM instance idsNeels Hofmeyr2019-04-122-2/+51
| | | | | | | | | | | | | | | | | | | | We often compose FSM instance IDs from context information, for example placing an MSISDN string or IP:port information in the FSM instance id, using osmo_fsm_inst_update_id_f(). This fails if any characters are contained that don't pass osmo_identifier_valid(). Hence it is the task of the caller to make sure only characters allowed in an FSM id are applied. Provide API to trivially allow this by replacing illegal chars: - osmo_identifier_sanitize_buf(), with access to the same set of illegal characters defined in utils.c, - osmo_fsm_inst_update_id_f_sanitize() implicitly replaces non-identifier chars. This makes it easy to add strings like '192.168.0.1:2342' or '+4987654321' to an FSM instance id, without adding string mangling to each place that sets an id; e.g. replacing with '-' to yield '192-168-0-1:2342' or '-4987654321'.

* add osmo_{escape,quote}_str_buf2() for standard args orderingNeels Hofmeyr2019-04-121-39/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be able to append an escaped or quoted string using OSMO_STRBUF_APPEND_NOLEN(), the function signature must have the buf and len as first args, like most other *_buf() functions. Add osmo_escape_str_buf2() and osmo_quote_str_buf2() to match this signature. A recent patch [1] has changed the return value of osmo_escape_str_buf() to char*, removing the const. However, the functions may return const strings, hence re-add the const. The new signatures always return the non-const buffer. To avoid code duplication, implement osmo_quote_str_buf() and osmo_escape_str_buf() by calling the new functions. I decided to allow slight changes to the behavior for current osmo_escape_str() and osmo_escape_str_buf(), because impact on callers is minimal: (1) The new implementation uses OSMO_STRBUF_*, and in consequence osmo_quote_str() no longer prints an ending double quote after truncated strings; Before, a truncated output was, sic: "this string is trunca" and now this becomes, sic: "this string is truncat I decided to not keep the old behavior because it is questionable to begin with. It looks like the string actually ended at the truncation boundary instead of the reason being not enough space in the output buffer. (2) The new osmo_escape_str_buf2() function obviously cannot pass-thru an unchanged char* if no escaping was needed. Sacrifice this tiny optimization feature to avoid code duplication: - it is an unnoticeable optimization, - the caller anyway always passes a string buffer, - the feature caused handling strings and buffers differently depending on their content (i.e. code that usually writes out strings in full length "suddenly" truncates because a non-printable character is contained, etc.) I considered adding a skip_if_unescaped flag to the osmo_quote_str_buf2() function signature, but in the end decided that the API clutter is not worth having for all the above reasons. Adjust tests to accomodate above changes. [1] 4a62eda225ab7f3c9556990c81a6fc5e19b5eec8 Ibf85f79e93244f53b2684ff6f1095c5b41203e05 Change-Id: Id748b906b0083b1f1887f2be7a53cae705a8a9ae
* add osmo_str_startswith()Neels Hofmeyr2019-04-112-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move from a static implementation in tdef_vty.c to utils.c, I also want to use this in osmo-msc. The point is that the telnet VTY allows unambiguous partly matches of keyword args. For example, if I have a command definition of: compare (apples|oranges) then it is perfectly legal as for the vty parser to write only compare app One could expect the VTY to then pass the unambiguous match of "apples" to the parsing function, but that is not the case. Hence a VTY function implementation is faced with parsing a keyword of "app" instead of the expected "apples". This is actually a very widespread bug in our VTY implementations, which assume that exactly one full keyword will always be found. I am now writing new commands in a way that are able to manage only the starts of keywords. Arguably, strstr(a, b) == a does the same thing, but it searches the entire string unnecessarily.

* fsm: support graceful osmo_fsm_inst_term() cascadesNeels Hofmeyr2019-04-111-6/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add global flag osmo_fsm_term_safely() -- if set to true, enable the following behavior: Detect osmo_fsm_inst_term() occuring within osmo_fsm_inst_term(): - collect deallocations until the outermost osmo_fsm_inst_term() is done. - call osmo_fsm_inst_free() *after* dispatching the parent event. If a struct osmo_fsm_inst enters osmo_fsm_inst_term() while another is already within osmo_fsm_inst_term(), do not directly deallocate it, but talloc-reparent it to a separate talloc context, to be deallocated with the outermost FSM inst. The effect is that all osmo_fsm_inst freed within an osmo_fsm_inst_term() cascade will stay allocated until all osmo_fsm_inst_term() are complete and all of them will be deallocated at the same time. Mark the deferred deallocation state as __thread in an attempt to make cascaded deallocation handling threadsafe. Keep the enable/disable flag separate, so that it is global and not per-thread. The feature is showcased by fsm_dealloc_test.c: with this feature, all of those wild deallocation scenarios succeed. Make fsm_dealloc_test a normal regression test in testsuite.at. Rationale: It is difficult to gracefully handle deallocations of groups of FSM instances that reference each other. As soon as one child dispatching a cleanup event causes its parent to deallocate before fsm.c was ready for it, deallocation will hit a use-after-free. Before this patch, by using parent_term events and distinct "terminating" FSM states, parent/child FSMs can be taught to wait for all children to deallocate before deallocating the parent. But as soon as a non-child / non-parent FSM instance is involved, or actually any other cleanup() action that triggers parent FSMs or parent talloc contexts to become unused, it is near impossible to think of all possible deallocation events ricocheting, and to avoid running into freeing FSM instances that were still in the middle of osmo_fsm_inst_term(), or FSM instances to enter osmo_fsm_inst_term() more than once. This patch makes deallocation of "all possible" setups of complex cross referencing FSM instances easy to handle correctly, without running into use-after-free or double free situations, and, notably, without changing calling code.

* fsm: add flag to ensure osmo_fsm_inst_term() happens only onceNeels Hofmeyr2019-04-111-0/+6
| | | | | | | | | | | To prevent re-entering osmo_fsm_inst_term() twice for the same osmo_fsm_inst, add flag osmo_fsm_inst.proc.terminating. osmo_fsm_inst_term() sets this to true, or exits if it already is true. Update fsm_dealloc_test.err for illustration. It is not relevant for unit testing yet, just showing the difference. Change-Id: I0c02d76a86f90c49e0eae2f85db64704c96a7674

* Add _c versions of functions that otherwise return static buffersHarald Welte2019-04-1014-11/+419
| | | | | | | | | | | | | | We have a habit of returning static buffers from some functions, particularly when generating some kind of string values. This is convenient in terms of memory management, but it comes at the expense of not being thread-safe, and not allowing for two calls of the related function within one printf() statement. Let's introduce _c suffix versions of those functions where the caller passes in a talloc context from which the output buffer shall be allocated. Change-Id: I8481c19b68ff67cfa22abb93c405ebcfcb0ab19b
* add osmo_use_count APINeels Hofmeyr2019-04-082-0/+280
| | | | | | | | | | | | | | | | | | | | | | | | | Provide a common implementation of use counting that supports naming each user as well as counting more than just one use per user, depending on the rules the caller implies. In osmo-msc, we were originally using a simple int counter to see whether a connection is still in use or should be discarded. For clarity, we later added names to each user in the form of a bitmask of flags, to figure out exactly which users are still active: for logging and to debug double get / double put bugs. This however is still not adequate, since there may be more than one CM Service Request pending. Also, it is a specialized implementation that is not re-usable. With this generalized implementation, we can: - fix the problem of inadequate counting of multiple concurrent CM Service Requests (more than one use count per user category), - directly use arbitrary names for uses like __func__ or "foo" (no need to define enums and value_string[]s), - re-use the same code for e.g. vlr_subscr and get fairly detailed VLR susbscriber usage logging for free.

* add osmo_sockaddr_str APINeels Hofmeyr2019-04-082-1/+381
| | | | | | | | | | | | | | | | | | | | | | | | For handling RTP IP addresses and ports, osmo-mgw, osmo-bsc and osmo-msc so far have their own separate shims and code duplication around inet_ntoa(), htons(), sockaddr conversions etc. Unify and standardize with this common API. In the MGW endpoint FSM that was introduced in osmo-bsc and which I would like to re-use for osmo-msc (upcoming patch moving that to osmo-mgw), it has turned out that using char* IP address and uint16_t port number types are a convenient common denominator for logging, MGCP message composition and GSM48. Ongoing osmo-msc work also uses this for MNCC. This is of course potentially useful for any other IP+port combinations besides RTP stream handling. Needless to say that most current implementations will probably stay with their current own conversion code for a long time; for current osmo-{bsc,msc,mgw} work (MGW endpoint FSM) though, I would like to move to this API here.

* gsm_utils: fix use buf_len instead of sizeof in osmo_dump_gsmtime_bufPhilipp Maier2019-04-081-1/+1
| | | | | | | | | | The function osmo_dump_gsmtime_buf gets a pointer *buf and a parameter buf_len. The pointer *buf is a string buffer and the function places an \0 at the end of the buffer before it exists. However it uses sizeof(buf) as part of the index calculation, which is incorrect. Lets correct this by using buf_len instead. Change-Id: Id24263aa7c9a53544f1639b6ceb09ce5615d5114
* Add _buf() functions to bypass static string buffersHarald Welte2019-04-0313-117/+337
| | | | | | | | | | | | | | | We have a number of static buffers in use in libosmo*. This means the related functions are not usable in a thread-safe way. While we so far don't have many multi-threaded programs in the osmocom universe, the static buffers also prevent us from calling the same e.g. string-ify function twice within a single printf() call. Let's make sure there's an alternative function in all those cases, where the user can pass in a caller-allocated buffer + size, and make the 'classic' function with the static buffer a wrapper around that _buf() variant.

* osmo_escape_str_buf: Always copy, don't return input string pointerHarald Welte2019-03-291-19/+8
| | | | | | | | | | | osmo_escape_str_buf() used to have the somewhat odd semantics that if no escaping was needed, it would return the original pointer without making any copy to the output buffer. While this seems like an elegant optimization, it is a very strange behavior and it works differently than all of our other *_buf() functions. Let's unify the API and turn osmo_escape_str_buf() into a strlcpy() if no escaping is needed. Change-Id: I3a02bdb27008a73101c2db41ac04248960ed4064

* ipa: Document ipa_ccm_idtag_parse_off and fix ipa_ccm_idtag_parsePau Espin Pedrol2019-03-281-1/+11
| | | | | | | | | | | | | | | | | | | | | ipa_ccm_idtag_parse_off is broken, and can only be used with len_offset=1 on ID Request messages, otherwise won't work correctly. Modify ipa_ccm_idtag_parse to at least parse those correctly, and document the limitations. Those two functions are already deprecated and only used in openbsc by 3 callers: * ipa_ccm_idtag_parse in ussd_read_cb(): Broken, that function can only work for Requests and it's used to parse a Response. * ipa_ccm_idtag_parse_off in forward_sccp_to_msc (NAT): Broken, it can only be used to parse Requests and it's used to parse a Response. Furthermore, len_offset=2 is passed which makes no sense and most probably it fails always, or can even make the program crash. * ipa_ccm_idtag_parse_off in (answer_challenge): This one is fine and could actually be replaced with ipa_ccm_id_get_parse after this commit is merged.

* gprs_ns_sns: Use "correct" remote IP address for local IP endpointHarald Welte2019-03-161-2/+2
| | | | | | | | | | | we cannot use "nsi->nsip.remote_ip", as this address is not set when SNS is in use. We can only have a valid nsi->nsip.remote_ip if there's only a single NS-VC inside the NS Instance, as this would connect() the UDP socket to the remote IP/port, breaking any possibility to have multiple NS-VCs to different SGNS-side IP addresses. Closes: OS#3845 Change-Id: Ic094621eb01d7458063f531289d5eeadf52bf330
* gprs_ns: Don't use initial IP/port for anything but SNSHarald Welte2019-03-161-2/+55
| | | | | | | | | | | | | | | | | | | | | | | Section 6.2.1 of 3GPP TS 48.016 states: > A pre-configured endpoint shall not be used for NSE data or signalling > traffic (with the exception of Size and Configuration procedures) unless > it is configured by the SGSN using the auto-configuration procedures. However, in the current SNS implementation, the initial IP/Port over which we perform the SNS-SIZE + SNS-CONFIG are treated as one of the normal NS-VCs. Specifically, we also perform the NS-ALIVE procedure on it, which is clearly wrong. Let's explicitly create the "initial" NS-VC with data and signalling weight of 0, and ensure we never start the alive timer or send any non-SNS PDUs on this connection as long as SNS was not used to change either of the two weights to non-zero. While at it, also safeguard against processing any incoming non-SNS messages on such a all-zero-weight connection. Change-Id: I16a91a07e5914d123b2ea2f8413b94e7cd518628 Closes: OS#3844
