Issue: 6855: Match sigmatch type field in var and bit structs
Align the size and datatype of type, idx, and next members across:
- FlowVarThreshold
- FlowBit
- FlowVar
- GenericVar
- XBit
- DetectVarList
Note that the FlowVar structure has been intentionally constrained to
match the structure size prior to this commit. To achieve this, the
keylen member was restricted to 8 bits after it was confirmed its value
is checked against a max of 0xff.

f->sgh_toserver may be NULL but because FLOW_SGH_TOSERVER is unset
and thus, we want to delay cleanup until detection has really been
run with the right signature group head.
This may happen for a rule using
`alert tcp any any -> any any` and
a app-layer keyword to client
with a app-layer supporting both udp and tcp
with stream.midstream=true
and with the first packet of a flow being a server response
In this case, we swap the flow and reset its signature group heads
Ticket: 7552
When we use midstream, and the first packet we see of a flow is
a response from server, and we want to match on some signature
to client :
- we had first set sgh_toserver/FLOW_SGH_TOSERVER as we first
thought this was a packet to server
- we then swap/reverse the flow, so sgh_toclient becomes sgh_toserver
but it contains signatures to server and cannot match our
to_client signature
The detect engine with DetectRunSetup will set again the
signatures group heads properly
Currently this script has two commands: "missing" and "having".
"missing" will show eve fields that do not map to any keywords.
"having" will sohw eve fields along with their keyword mappsings,
while also validating that those keywords really exist.

To some EVE fields and a "suricata" object that contains an array of
keywords. These are the keywords that map directly to this field, or
somehow cover this field.
This is an attempt at tooling to help with EVE and keyword parity.

Add keywords dns.additionals.rrname and dns.authorities.rrname. Along
the way, consolidate dns.query.name and dns.answer.name into a single file
and register them altogether since there is a lot of common code.
Split DetectHelperKeywordRegister into 2 functions, one for acquiring
a new keyword ID, and another to perform the registration.
This makes it easier to do the traditional C keyword initialization
with a dynamic ID.
Feature: 7012
Add dns.response sticky buffer to match on dns response fields.
Add rust functions to return dns response packet data.
Unit tests verifying signature matching.

When HTTP1 post multipart handles a small file, it will call
HTPFileClose with some data
This data needs to be appended to the streaming buffer for usage
by file.data keyword even if we do not end up storing the file
ldap.responses.message matches on LDAPResult error message
This keyword maps the following eve fields:
ldap.responses[].bind_response.message
ldap.responses[].search_result_done.message
ldap.responses[].modify_response.message
ldap.responses[].add_response.message
ldap.responses[].del_response.message
ldap.responses[].mod_dn_response.message
ldap.responses[].compare_response.message
ldap.responses[].extended_response.message
It is a sticky buffer
Supports prefiltering
Ticket: #7532
ldap.responses.result_code matches on LDAP result code
This keyword maps the following eve fields:
ldap.responses[].bind_response.result_code
ldap.responses[].search_result_done.result_code
ldap.responses[].modify_response.result_code
ldap.responses[].add_response.result_code
ldap.responses[].del_response.result_code
ldap.responses[].mod_dn_response.result_code
ldap.responses[].compare_response.result_code
ldap.responses[].extended_response.result_code
It is an unsigned 32-bit integer
Doesn't support prefiltering
Ticket: #7532
Funciton ldap_tx_get_responses_dn returns empty buffer in case
the response doesn't contain the distinguished name field
Fixes: 73ae6e997f ("detect: add ldap.responses.dn")
Change variable name 'req' to 'resp' in function ldap_tx_get_responses_dn and documentation nits
Fixes:
73ae6e997f ("detect: add ldap.responses.dn")
16dcee46fc ("detect: add ldap.request.dn")
- remove rs_prefix, replace with SC if needed
- remove pub and no_mangle where not needed
- remove some unused functions and fields

This uses the cbindgen found during ./configure, and not the one
found on the path during "make", which while often the same, aren't
always the same.
Ticket: #6384
The RPM has been updated to handle the conversion of suricatasc and
suricatactl to Rust.
Also fixes the "if" expression to prevent one job running both upload
sections.
There will be changes in our development branch that the RPMs need to
adapt to, but that can't be done until the changes have been merged to
master, then the RPM can catchup.
This gives us a single variable to turn off RPM building.
