Issue: 5718
This commit switches the majority of time handling to a new type --
SCTime_t -- which is a 64 bit container for time:
- 44 bits -- seconds
- 20 bits -- useconds
This commit adds a function to make a deep copy of a DetectThresholdData
object.
The function is used when parsing threshold.config items to make a
one-time object and then add copies as needed.
The only difference between threshold calculations for by_src/by_dst,
by_rule or by_both is which table stores the DetectThresholdEntry.
Refactor the ThresholdHandlePacket* functions to do table lookup and
storage individually, but calculate thresholds in a common function.
So far suppress rules would apply to src or dst addresses of a packet.
This meant that if a ip would need to suppressed both as src and as dst,
2 suppress rules would be needed.
This patch introduces track by_either, which means that the ip(s) in the
suppress rule are tested against both the packets source and dest ip's.
If either of them is on the suppress list, the alert is suppressed.
Ticket: 1137
Support supplying a list of IP's to the suppress keyword. Variables from
the address-groups and negation is supported. The same logic (and code) is
used that is also used in parting the IP portions of regular detection
rules.
