Holger Hans Peter Freyther c62a1bf4d5 libosmogb: Add function to close NS instance without destroying it 2013-07-06 23:36:16 +02:00
Harald Welte 27b2bb7e92 BSSGP: prevent divide-by-zero in flow control 
If the BTS tells us to not send any data at all anymore (bucket leak
rate of 0 bits per second), then we should respect this and not run into
a divide-by-zero.  However, as this indicates complete overload, we
print a log message to that regard.

Tobias Engel 597460fd97 Do not use --version-script linker flag on OSX 
Add a check to not use --version-script linker flag if compiled on OSX
since it doesn't exist there

Tobias Engel 2db368ee8d Define struct iphdr for OSX 
Use FreeBSD struct iphdr definition for OSX also. From the commentary in
the source file:
On BSD the IPv4 struct is called struct ip and instead of iXX
the members are called ip_XX. One could change this code to use
struct ip but that would require to define _BSD_SOURCE and that
might have other complications. Instead make sure struct iphdr
is present on FreeBSD.

Andreas Eversberg aaccdac55d Fix: gprs_ns_destroy() now frees all NSVCs and its timers 
Freeing memory of registered timers and file descriptors cause corrupt
lists.

Harald Welte e92866bbb1 Gb: Add functions for sending flow control messages from BSS side 2012-09-10 08:56:04 +02:00
Harald Welte 30fabdf61d Gb: Add header file for BSS-side BSSGP functions 
.. not sure how we could have missed that so far.

Harald Welte e3a10b66a4 libosmogb: make build conditional, disable in embedded build 
when we build for osmocom-bb cross-compilation, we don't have
sockets nor netinet/in.h and thus NS/BSSGP make no sense...

Harald Welte 0823e1e42a BSSGP: print per-bvc flow control parameters on vty 2012-09-07 12:13:09 +02:00
Harald Welte d8b476988d BSSGP: make bvc_ctx->fc a dynamic talloc allocation 
this ensures that we can talloc the flow-control queue entries
as siblings off the bvc_ctx.

Harald Welte bb8262275f BSSGP flow-control: various fixes 
* add more comments on units of struct members
* make sure to parsre FC-BVC message correctly
* add error message in case user passes PDU larger than bucket size
* add new function to initialize flow control struct

Harald Welte d11c059502 libosmogb: Port BSSGP flow control from openbsc/laforge/bssgp_fc branch 
This code is supposed to implement the BSSGP flow control algorithm,
both for the per-BSS and for the per-MS flow control.

The code currently has no test cases, they will come in a separate
commit.

Harald Welte ca0af8a3a8 libosmogb: build without strict aliasing rules 
This allows us to reliably do the trick with casting structures like
libgb_msgb_cb to the msgb->cb[] array.  Shamelessly stolen from the
Linux kernel.

Holger Hans Peter Freyther d296f4244f gb: Make suspend_ref a plain uint8_t instead of a uint8_t* 
The OpenSUSE build is not happy about the uint8_t to uint8_t*
assignment. As the suspend_ref is a mandatory field we can make
it a plain uint8_t. Increase the LIBVERSION as the ABI has changed.

Holger Hans Peter Freyther 5a19bf7ccb libgb: Link to the libraries used by libgb 
The Mandriva linker appears to be more strict in enforcing the
as-needed rules. Link to the libraries that are used by libgb.

Andreas Eversberg aa5d0e8894 Fix encoding of BSSGP_IE_NUM_OCT_AFF in bssgp_tx_llc_discarded() 
This is a 24bit integer value, and thus we need to encode the three
least significant octets of the network-byte-order 32bit value, not the
three most significant octets.

Holger Hans Peter Freyther 3c16de2954 freebsd: Make libgb compile on FreeBSD 
Include header files for recfrom/AF_INET and include a
struct ip_hdr as it is not available on *BSD.

Harald Welte 2d956a82c8 bssgp: check for IMSI being a null pointer, not just an empty string. 2012-07-04 21:55:23 +02:00
Diego Elio Pettenò c5f055f9e5 build: use LT_INIT(pic-only) instead of forcing -fPIC. 
This actually allows for the user to override the decision and at the
same time supports compilers that might not be able to use -fPIC at
all.
