* gsm/gsm48_ie: Fix Range 256 format decodingSylvain Munaut2011-09-011-20/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the mail: --- appended is another patch for fixing a bug in the calculation of the frequency lists. This time the patch is for the "Range 256 format". The problem is that the operand for the "smod" operation might be negative, in this case the simplified version won't work as expected. In the patch I introduced a separate function for "smod" which takes care of the sign. I have not yet checked if the other formats are also affected, this would be the case if the "smod" operand can be negative. There might be other solutions to fix the problem without the need for a separate function, however I have not thought further about it. A test vector is the following frequency list ("Range 256 format", first byte is the length): 09 8b 1c 83 8c 15 ef 02 2d 30 The correct ARFCNs are 569 571 576 578 586 608 712 715 719 The uncorrected version would instead return: 444 457 460 464 569 576 578 586 608 This means four ARFCNs are wrong which will cause problems if for example the frequency list contains the ARFCNs for hopping. ---- Written-by: Dieter Spaar <spaar@mirider.augusta.de> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
* add functions for bit-reversalHarald Welte2011-09-011-0/+57
| | | | | Sometimes we need stuff like reversing every bit in each byte (but not the byte-order).

* sms: SMS where cropped (from VTY), concatenation of SMS where not possibleDennis Wehrle2011-07-241-29/+89
| | | | | | | | | | | | Additionally it wasn't possible to send concatenated sms from the vty. To send multiple sms, it is necessary to use padding bits and add a user_data_header. Therefore the gsm_7bit_encode function was splitted to gsm_7bit_encode and gsm_septets2octets. gsm_septets2octets: this is the old gsm_7bit_encode function + additional padding parameter Additionally the gsm_7bit_decode function was modified to take account for the user_data_header. With the new gsm_get_octet_len function you can get the octet length for a given septet length. I also added several sms tests.
* remove DLRSL and DLNM, we don't need themHarald Welte2011-07-211-12/+0
| | | | | They are not used anywhere in our libraries, so they should be defined by the respective applications
* make sure we don't have namespace clashes between libraries and appsHarald Welte2011-07-191-6/+6
| | | | | | | | * All loging prefixes in libraries should be DL like DLINP * All signals / subsystems should be called S_L_* SS_L_* * All command nodes should be called L_*_NODE This makes sure existinc code still compiles as expected
* logging: add libosmo-abis logging subsystemsPablo Neira Ayuso2011-07-181-0/+34
| | | | | | This adds the libosmo-abis logging subsystems to libosmocore, it uses the new change that harald proposed based on negative numbers for library logging subsystems.

* tlv: Make tlv parser arrays 256 entries wide to prevent overflow on 0xffHarald Welte2011-07-161-1/+1
| | | | | | | If we encounter a tag with 0xFF, we overflow our existing tlv_parse array definitions. Warning: this breaks ABI

* osmo_hexdump: Fix segfault when input is too long.Holger Hans Peter Freyther2011-07-151-0/+2
| | | | | | | | | | In snprinftf the size is a size_t (unsigned) in case we want to write more than we have available, len_remain will be < 0. This was spotted while removing hexdump from simtrace and comparing it to our implementation. int snprintf(char *str, size_t size, const char *format, ...);
* GSM 08.08: Fix generation of CIPHER MODE REJECTHarald Welte2011-07-121-1/+1
| | | | | The message has a total length of 4 octets, so don't allocate only 3 in the msgb.

* fix against corrupted output in parallel loggingHarald Welte2011-07-021-1/+1
| | | | | | | | | In 825607672215b7a12ea6e201a89cd5209f6d657f it was attempted to fix a bug previously introduced by logging related changes. The problem is that a va_list can be corrupted after it has been used once, so we need to va_copy before each successive use. And if we copy it, we also need to use the copy, and not the original ;)
* lapdm: make sure we flush all queues whenever entering IDLE stateHarald Welte2011-06-291-0/+11
| | | | | this fixes a memory leak where the final UA would always remain in memory after a LAPDm entity has been disconnected.

* logging: introduce library-internal logging categoriesHarald Welte2011-06-272-21/+93
| | | | | | | | | | We do this by using a trick: library-internal log categories use negative subsystem numbers, which are converted into positive array indexes at the time of logging. library-internal log categories need to be knwo at compile-time, while application-specified categories now are of unlimited number, as they are dynamically allocated.
