[PATCH libosmocore 0/8] Cell Broadcast (SMSCB) MS support
by Alex Badea 06 Jan '13

06 Jan '13

Hi, This a respin of my old series of patches[1], to add decoding of SMSCB messages on the MS side. The series defines a new smscb_entity, which can be fed L1 messages from a CBCH, performs reassembly, and constructs equivalent SMS Broadcast Command (RSL_MT_SMS_BC_CMD) messages for L3. I also have a follow-up patch for bb/cell_log which makes use of this functionality. Please review and consider for merging, thanks.

[PATCH libosmocore] doxyfiles: refer paths to @srcdir@
by Alex Badea 06 Jan '13

When building out-of-srcdir, paths such as "src/gsm" will not find any source files. Since the Doxyfiles are preprocessed, we can prepend @srcdir@ to fix that.

[PATCH libosmocore] timer_test: tweak path to config.h
by Alex Badea 06 Jan '13

06 Jan '13

When building out-of-srcdir, "../../config.h" fails to reach config.h because the compiler is invoked in $builddir/tests/, not $builddir/tests/timer/.

libosmocore: [PATCH] Replace obsolete automake AM_CONFIG_HEADER.
by Christian Vogel 06 Jan '13

06 Jan '13

Hi, I just setup a machine running ArchLinux which has a pretty recent automake/autoconf. libosmocore fails to build. Attached (trivial) patch fixes that. Someone with a really old toolchain/automake should check if it breaks setups we consider supported. Chris

[PATCH] layer23 cell_log: log CBCH cell info
by Alex Badea 05 Jan '13

05 Jan '13

If System Information contained CBCH channel description, tune to it and log SMSCB messages with a Geographical Scope of Cell Wide (Immediate) -- these are typically used for "Cell Info Display". The CBCH timeout is set to a generous 8 seconds; this is because we need 4 frames for reassembly, we usually miss the first, and we might hit a burst of Null SMSCB messages. By default this feature is disabled; it can be enabled via a new '-B' or '--cbch' commandline argument. Signed-off-by: Alex Badea <vamposdecampos(a)gmail.com> --- This patch requires the CBCH DM flag patch[1], and the libosmocore patch series[2] for SMSCB reassembly.

[PATCH] core/msgb: Change return value of msgb_pull to the start of pulled header
by Sylvain Munaut 05 Jan '13

05 Jan '13

From: Sylvain Munaut <tnt(a)246tNt.com> Currently msgb_pull returns a pointer to the new start of msgb, which is pretty counter intuitive and when using msgb_pull is often annoying. For eg, the msgb_pull_u{8,16,32} were previously "fixed" for this quirk in a previous commit. The msgb_pull_l2h in lapdm is also wrong because of this, same for code in osmocom-bb loader. AFAICT, the current users of msgb_pull either don't care about the return value, or expect it to be a pointer to the pulled header and not the new start of msgb (and so are currently buggy). Without this patch, you have things like: struct foo *bar = msgb_pull(msg, sizeof(struct foo)) - sizeof(struct foo) With the patch, you have: struct foo *bar = msgb_pull(msg, sizeof(struct foo)); which is IMHO a much better style.

fix of osmoload, flashing c155 works
by jolly 05 Jan '13

05 Jan '13

hi, just fixed the issue from 29c3, where flashing of phones did not work anymore. if no one complains, i will apply it. it is also possible to flash c155 phones. the original compal boot loader will start firmware at 0x20000 instead of 0x2000 (c123), so i modified the linker scripts for compal_e99. i am not sure, if all c155 phones behave the same. to check this, i dumped some pages of the flash memory: run the loader: $ host/osmocon/osmocon -p /dev/ttyUSB0 -m c155 target/firmware/board/compal_e99/loader.compalram.bin start the phone and dump some flash: $ host/osmocon/osmoload memdump 0x000000 0x30000 dump a hexdump of that dump showed me where the actual firmware starts: ... 0000800 4f42 544f 392e 2e30 3530 0000 0000 0000 0000810 3031 3330 0101 0000 ffff ffff ffff ffff 0000820 ffff ffff ffff ffff ffff ffff ffff ffff * 0020000 4f43 4544 392e 2e30 3130 0000 0000 0000 0020010 4c46 5845 392e 2e30 3130 302e 0031 0000 0020020 5352 4b50 392e 2e30 3130 302e 0031 0000 ... i would like to know, if this is true for other c155 phones. regards, andreas

No r-gsm cell shown in mobile app
by Karsten Krummeich 05 Jan '13

05 Jan '13

Hi, I'm thinking about why the mobile app don't show me the German GSM-R (MCC: 262, MNC: 10) cells they are around me. The rssi app shows me the cells (e. g. ARFCN: 957 and 961). I'm using the sylvain/testing branch and I am searching for more details in the source code and found in settings.c that the r gsm band are enabled and in the freq_list. Can someone tell me another point for searching in source? Thanks in advance. Best regards. kasio
