* msgb: fix msgb_pull_u*()Steve Markgraf2012-11-141-3/+3
| | | | | | | | msgb_pull returns a pointer to the new begin of the buffer, unlike msgb_get(), where those functions were originally taken from. Signed-off-by: Steve Markgraf <steve@steve-m.de>
* logging: Introduce a print_filename flag for the logtargetHolger Hans Peter Freyther2012-09-111-0/+3
| | | | | | Introduce a print_filename attribute for each logtarget. Initialize it with 1 to be backward compatible with earlier versions. The bit is taken from an existint bitfield. There were at least six bits left of the byte.
* logging: Mark the log_info_cat pointer as constsHolger Hans Peter Freyther2012-09-111-1/+1
| | | | | | Applications should keep the log area in a static const area. Mark the pointer as const to address compiler warnings in OpenBSC, cast the const away for the osmo_log_info as it is not declared as const.
* msgb: msgb_get() is supposed to get bytes from END, msgb_pull() from HEADHarald Welte2012-09-081-3/+34
| | | | | | msgb_get() has been wrong all the time, despite the documentation being correct. If you've used the broken msgb_get() before, you have to change your code now, sorry.
* gsmtap: add minimal support for encapsulating UMTS RRC in GSMTAPHarald Welte2012-09-021-0/+7

* utils: Change semantic of OSMO_MAX/OSMO_MIN to match semantic of a functionHolger Hans Peter Freyther2012-08-151-2/+2
| | | | | | | Add parentheses around the OSMO_MAX and OSMO_MIN macro to match the behaviour of calling a function. The current version does not evaluate to what is expected. (OSMO_MAX(3, 2) + 13) currently results in 3 and not 16.
* backtrace: Add a variant that uses the libosmocore logging frameworkHarald Welte2012-07-141-0/+1
| | | | | | I recently discovered that we can only print backtraces to stdout, which is of course useless in a daemon environment. We'd rather want to use the libosmocore logging framework instead.
* timer: Add function osmo_timer_remaining() to determine remainign timeHarald Welte2012-07-131-1/+3

* logging: Fix compile breakage introduced by the warning fixesHolger Hans Peter Freyther2012-07-121-1/+1
| | | | | | | | | | | | Make sure the declaration and definition match, add const to the functions called by logp/logp2. Compile output: logging.c:317: error: conflicting types for 'logp' ../include/osmocom/core/logging.h:34: note: previous declaration of 'logp' was here logging.c:327: error: conflicting types for 'logp2' ../include/osmocom/core/logging.h:168: note: previous declaration of 'logp2' was here make[3]: *** [logging.lo] Error 1
* logging: Avoid compiler warnings when compiling c++ codeAndreas Eversberg2012-07-101-2/+2
| | | | | | this patch i use to suppress warnings when compiling osmo-pcu (c++). since __FILE__ is constant, the called logging function with parameter "file" must be constant too, in order to avoid compiler warnings.
* build: simplify headers management and remove recursionDiego Elio Pettenò2012-06-301-31/+0
| | | | | | | | | | | | There is no real reason to keep the include directory a multi-level recursion, so instead declare everything within include (so that we can use proper nobase_ declarations) and be it. Please note that since we removed the sub-Makefile.am, ./configure will not create the directory structure for us on out-of-tree builds, so we have to make sure the directory we're generating to exists first.

* gsmtap: Add GSMTAP_GPRS_CS() / GSMTAP_GPRS_MCS()Harald Welte2012-02-081-0/+8
| | | | | | | | As requested by Mike Morrin <Mike.Morrin@ipaccess.com>, we introduce GSMTAP sub-types for all the different GPRS and EGPRS coding schemes. This is neccessary due to the fact that the RLC PDU doesn't contain any explicit indication of the coding scheme used on the radio layer.

* msgb_trim(): actually trim to an absolute length, as the comment statesHarald Welte2012-01-141-5/+3
| | | | | The previous commit introduced a new msgb_trim() but the implementation differed from the specification.

* core/conv: Add support for other termination types (trunc & tail biting)Sylvain Munaut2011-11-241-6/+25
| | | | | | | | Note that this breaks the ABI and the low level API. But it shouldn't break the high level API, nor the conv code definitions (because fields default to 0, and for new fields '0' is the previous behavior) Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

* utils: Add declaration back for osmo_osmo_hexdump_nospcSylvain Munaut2011-11-131-0/+1
| | | | | | | | As it turns out, if a project uses the old name but without a declaration, it'll causes a segfault on 64 bits platform (because of the implicit int return type which doesn't apply since here it's a pointer). Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

* core/rbtree: add const qualifier to some functionsSylvain Munaut2011-11-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | See kernel commit f4b477c47332367d35686bd2b808c2156b96d7c7 ---- The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls take a pointer to an RB node or RB root. They do not change the pointed objects, so add a 'const' qualifier in order to make life of the users of these functions easier. Indeed, if I have my own constant pointer &const struct my_type *p, and I call 'rb_next(&p->rb)', I get a GCC warning: warning: passing argument 1 of ?~@~Xrb_next?~@~Y discards qualifiers from pointer target type Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> ---- Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

* timer: add scalable RB-tree based timer infrastructurePablo Neira Ayuso2011-10-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds RB-tree based timers which scales better than the previous list-based implementation. It does not require any API changes. It breaks ABI because the osmo_timer_list structure has changed though (to avoid this in the future, we can put internal data in some private structure). The following table summarizes the worst-case computational complexity of this new implementation versus the previous one: rb-tree list-based ------- ---------- calculate next timer to expire O(1) O(n) insertion of new timer O(log n) O(n) deletion of timer O(log n) O(1) timer-fired scheduler O(log n) O(3n) The most repeated cases are: * the calculation of the next timer to expire, that happens in every loop of our select function. * the timer-fired scheduler execution. This new implementation only loses in the deletion of timer scenario, this happens because we may need to rebalance the tree after the removal. So I think there is some real gain if we have some situation in which we have to handle lots of timers.
* add rb-tree implementation to libosmocorePablo Neira Ayuso2011-10-172-1/+161
| | | | | | | | | This patch adds red black trees implementation to libosmocore. This data structure is very useful to search for elements in ordered sets in O(log n) instead of O(n) that lists provide. The first client of this code will be one follow up patch that implements rbtree-based timer scheduler.
