Jason Ish 713e4eb900 ntp: convert reference_id to buffer and add keyword
Store the NTP reference ID as raw network-order bytes so it can be
exposed as a sticky buffer and matched with payload keywords. The
reference ID is often a 4 character string, or an IP address and not
just an integer identifier.

Updates the log reference ID to be a string of colon separated hex
digits as this matches what tshark does.

Jason Ish 879846e153 ntp: remove unused event types
NotRequest and NotResponse event type have never been used.

Unsolicited is also unused, however there is a rule for it so removing
support would be a breaking change at this time.

Philippe Antoine 63603fe14a detect/snmp: sticky buffers at progress 1
Since snmp txs are created at progress 1 which is the completion,
this does not change detection, except allowing firewall mode
to use these keywords with generic hook like
snmp:request_complete

Philippe Antoine 8f824458c2 detect: helper for buffer register requires progress
Ticket: 8395

For protocols where tx are complete at start, that is
the `tx_get_progress` function returns 1 inconditionnally,
we can use the progress 1, not losing time on detection in ips
mode, and getting ready for firewall mode

For the other protocols (where a tx needs both a request and response
for instance), keep progress 0 as was the case before

Philippe Antoine 2fa10052cf websocket: check pdu opcode for reassembly
Ticket: 8413

RFC 6455 Section 5.4 states

Control frames (see Section 5.5) MAY be injected in the middle of
a fragmented message.

Control frames are identified by opcodes where the most significant
bit of the opcode is 1.

Philippe Antoine 784e173278 http2: bound number of http2 frames per tx
Ticket: 8289

If stream.reassembly.depth is unlimited,
an attacker controlling the 2 sides of a communication going through Suricata
can send a transition with an infinite number of headers, until suricata OOMs

Solution is to offer a configuration option to bound the number
of HTTP2 frames we store in a HTTP2 transaction, and produce an
anomaly if this bound is crossed

Philippe Antoine 49fd7001ff smtp/mime: fix urls finding in buffering case
We used to look for a full line, but as we look fot the last eol
we need to use the right index in the not-reversed list
6 months ago
Philippe Antoine 8bba47aa09 smtp/mime: avoid quadratic complexity in mime_smtp_find_url_strings
Ticket: 8292

When we have buffered something in ctx.decoded_line,
we already looked for '\n' in it, so we do not need to run it again

Otherwise, callers that supply mime_smtp_find_url_strings with
a few bytes at a time without "\n", have a quadratic
complexity
