Holger Hans Peter Freyther 5dff9f9ef5 jenkins: Add the build script from jenkins here 
This can be used to replicate a build issue more easily.

Holger Hans Peter Freyther c016b5d382 Make a new release with 64bit client fixes 2015-12-03 22:17:26 +01:00
Holger Hans Peter Freyther 66b80cc8f5 client: Deal with external representation for pcap files 
We need to convert the 64bit timeval on a 64bit userspace (or on
OpenBSD) into a 32bit truncated value for being able to write the
file. This means we have 2038 issue here?

Holger Hans Peter Freyther 42421c4f7e client: Allow receiving jumbo frames on the client as well 
Check the caplen and see if it is bigger than our assumed
maximum. Make sure we have enough space for data+hdr+hdr.

Holger Hans Peter Freyther ff1a5dc751 server: Deal with jumbo frames on the wire 
The 2000 as a number is too small. Modern networks can have a
higher MTU (up to 9000). Take this number and assume there is
a big header in front of it.

Holger Hans Peter Freyther 74f89c6119 gprs: Do not collect BVC FLOW CONTROL / ACK messages 
These generate a high amount of traffic. They are good to debug
ip.access nanoBTS GPRS crashes/service outage but in general cause
too much traffic.

Holger Hans Peter Freyther ae5ec91a40 gprs: Remove left over for counting llc frames 
These variables were used to verify how many LLC frames were
seen.
 2015-09-10 17:02:18 +02:00
Holger Hans Peter Freyther b7a834b4cb gprs: Add a custom GPRS filter 
Allow to inspect UDP messages and check for GPRS, NS, BSSGP
and then filter LLC frames. Parsing the vL datastructure with
the libpcap syntax is a pain. It could be done using BPF but
we do not want to use bpf asm to specify the entire ruleset.

I looked into using libepan/libwireshark but this has memory
issues and is painful too. So let's parse UDP, NS, BSSGP using
the info we already have. I tried a bit of editcap to generate
a bit of broken data. The length check might still be bad.

I used my crash_20100602.pcap file to count the LLC frames we
detect and compare that to wireshark it ended with the right
number.

  pcap add-filter gprs

can be used to enable the new filtering option after the OS
has received the packet.

* Kill based on the PID file and not the name

Holger Hans Peter Freyther 0741879e11 cron: Deal with '-' in the name of a client. 
Do not stop when seeing the first '-'. E.g. if you have names like
tpe-system1, tpe-system2 they were treated as tpe and it was possible
that a currently opened file was deleted.

Daniel Willmann b000368ad6 Catch up with API change in osmo_sock_init 
The connect0_bind1 parameter has been replaced by a generic flag
parameter. With this patch osmo-pcap works (only) with versions of
libosmocore 0.3.2 or newer - configure.ac changed to reflects that.
