* origin/topic/dnthayer/ftp-ipv6:
Add test case for FTP over IPv4
Fix IPv6 URLs
Add a test for FTP over IPv6
Update FTP EPSV response processing for IPv6
Fix parsing of FTP EPRT command and EPSV response
Conflicts:
src/bro.bif
Closes#778.
Also fix IPAddr::Mask/ReverseMask not allowing argument of 0.
And clarified return value of to_addr bif when the input string
does not parse into a valid IP address.
* simple testcase for file refresh (check for changes) and streaming reads
* add events for simple put and delete operations
* fix bugs in table filter events (type for first element was wrong)
* and I think a couple of other small bugs
pass yet.
Changes:
- Gave IPAddress/IPPrefix methods AsString() so that one doesn't need
to cast to get a string represenation.
- Val::AsAddr()/AsSubnet() return references rather than pointers. I
find that more intuitive.
- ODesc/Serializer/SerializationFormat get methods to support
IPAddress/IPPrefix directly.
- Reformatted the comments in IPAddr.h from /// to /** style.
- Given IPPrefix a Contains() method.
- A bit of cleanup.
* change internal reader interface again
* remove some quite embarassing bugs that must have been in the interface for rather long
* add different read methods to script & internal interface (like normal, streaming, etc). Not implemented in ascii reader yet.
- non-binpac DNS analyzer now also generates dns_a6_reply event
- ExpectedConn class refactored to use IPAddr's
- BinaryExpr::AddrFold simplified
- IP_Hdr src/dst address accessor methods changed to construct IPAddr
objects on the fly from ip4/ip6 members.
Addresses #770.
- Large rework on packet filter framework to make many things easier.
- Removed the PacketFilter::all_packets variable because it was confusing.
- New variable (PacketFilter::enable_auto_protocol_capture_filters) to re-enable the old filtering model of only sniffing ports for analyzed protocols.
- In progress plugin model for adding filtering mechanisms.
- New default single item for capture_filters = { ["default"] = PacketFilter::default_capture_filter };
- Mechanism and helper functions to "shunt" traffic with filters.
- Created the Protocols framework to assist with reworking how base protocol scripts are registered with DPD and other things.
- Protocols framework creates BPF filters for registered analyzers. (if using PacketFilter framework in that mode).
