2015-12-03	server: Deal with jumbo frames on the wire	Holger Hans Peter Freyther	1	-1/+5
	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.
2015-09-10	gprs: Add a custom GPRS filter	Holger Hans Peter Freyther	1	-0/+1
	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.

2011-06-01	osmo-pcap-server: Try to read the the data with a simple state machine	Holger Hans Peter Freyther	1	-0/+10

2011-06-01	wireformat: Send the length in the network order..	Holger Hans Peter Freyther	1	-2/+2
	this is a format change. but it is necessary now.
2011-06-01	osmo-pcap-server: Prepare a file limit, initialize the base path	Holger Hans Peter Freyther	1	-0/+1

2011-05-31	osmo-pcap-server: Accept the client connection from a given host	Holger Hans Peter Freyther	1	-0/+8
	We now read from a given system.
2011-05-31	osmo-pcap-server: Work on the generic VTY interface for the server	Holger Hans Peter Freyther	1	-0/+3
	Work on being able to configure clients that are allowed to connect to the server.
2011-05-31	osmo-pcap-server: Start with the skeleton of the pcap server	Holger Hans Peter Freyther	1	-0/+67

2011-05-31	osmo-pcap-client: Connect to a server, send the data to it	Holger Hans Peter Freyther	2	-1/+56

2011-05-31	osmo-pcap-client: Set the filter string on the pcap device..	Holger Hans Peter Freyther	1	-1/+1

2011-05-31	osmo-pcap-client: Work on the client code, be able to open the device	Holger Hans Peter Freyther	1	-1/+15
	Add vty code to allow changing the device, this will just attempt to open and close the device. Nothing else is done.
2011-05-31	osmo_pcap_client: Start with the framework for the pcap client	Holger Hans Peter Freyther	3	-1/+85
	This is just the normal skeleton for the osmocom code.
2011-05-31	osmo-pcap: Create a dummy client.	Holger Hans Peter Freyther	1	-0/+1
