2016-09-08	client: Initial support for TLS in the client	Holger Hans Peter Freyther	1	-0/+16
	Use GNUtls because it is GPL compatible and instead of mbedTLS seems to have a working non-blocking I/O integration. GNUtls has various issues that could not be resolved easily: * Pick spdy as sub protocol * gmt_time not randomized * private key loaded to RAM (but not verified) This is the beginning and not the end. Client support might need more work with actual tls verification. Maybe more manual x509 cert verification is needed and maybe client certs don't work at all. I try to ignore renegotiation as I threw away the key. Reload x509 creds and keys as they might have changed from one connection to another. Change-Id: I9128e14084da1fc2705f858393f98b8133996172

2016-08-19	client: Use pcap_stats and export them as statistics	Holger Hans Peter Freyther	1	-0/+8
	Attempt to write code that detects the wrap and is doing the right thing when it happens. Change-Id: I501ebc49d3e86b0605ec1fbe2f62aee3f362aa36
2016-08-19	client: Additional counters for the statistics	Holger Hans Peter Freyther	1	-0/+2
	Add more counters and start counting them when reading from the PCAP library and when trying to write to the socket. Change-Id: I52d3064a265b402ac849d8578a14f718156c0805
2016-08-18	client: First round of statistics in the pcap client	Holger Hans Peter Freyther	1	-1/+14
	Count certain events that can help to understand what is going on. This includes OOM, failure to queues. Change-Id: I4a2dad32afb577822c7181d2813ea5a7e693c704
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. Fixes: ONW#1314
2011-05-31	osmo-pcap-client: Connect to a server, send the data to it	Holger Hans Peter Freyther	1	-1/+10

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	1	-0/+34
	This is just the normal skeleton for the osmocom code.
