2016-01-28trafgen: Add helper to get current packetVadim Kochan2-0/+7
Add current_packet() helper for getting current used packet and make it public to other modules. It will be used by proto generation logic. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2016-01-27netsniff-ng: Rename proto_vlan.h to vlan.hTobias Klauser3-9/+4
The proto_ prefix is reserved for dissectors and the header contains helper functions not exclusive to the proto_vlan dissector, so give it a more generic name. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-01-27ring: Make needlessly global function join_fanout_group() staticTobias Klauser1-1/+1
This fixes the following sparse warning: ring_rx.c:197:6: warning: symbol 'join_fanout_group' was not declared. Should it be static? Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2016-01-21mausezahn: Fix reading of hex payload fileThomas Fleischmann1-2/+6
Using the option -F with mausezahn, to read input out of a hexfile, results in corrupt data transmitted (first byte will always be 0). Properly parse "payload="/p=" at the start of the file by the same method as used in layer3.c and layer4.c Closes #153 Reference: http://permalink.gmane.org/gmane.linux.network.netsniff-ng/600 Signed-off-by: Thomas Fleischmann <thomas.fleischmann.08@googlemail.com> Reported-by: Thomas De Schampheleire Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-01-14trafgen: Simplify ring size unit parsingVadim Kochan1-12/+7

2016-01-14trafgen: Simplify 'gap' option unit parsingVadim Kochan1-8/+3

2016-01-12trafgen: Move gap feature into shaper logicVadim Kochan1-28/+40

2016-01-12flowtop: Use one nfct handle for dump & refresh flowsVadim Kochan1-13/+1
Simplify dump & flows refreshing via one nfct handle, which is enough. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-01-12flowtop: Use single function to update flow entryVadim Kochan1-51/+33
There is no need to have 2 separate handlers for the flow updating, so use the one which was used for flow refreshing. Significant change is that a new flow entry will be not added during update (i.e. on NFCT_T_UPDATE events) if it was not found in the list. But this case shoud never happen as there will always be an NFCT_T_NEW event before an NFCT_T_UPDATE event.
