As this is the default for websocket, which is bigger than the
defaut for zlib usage
Also limit the decompressed content to the max-payload-size
configuration parameter also used for non-compressed content.
And also use a stateful decoder to store/remember the compression
state to be able to decompress later messages.
move flate2.rs to a backend supporting the setting
of window_bits, which is not the case for miniz-oxide.
This will allow WebSocket to use Sec-WebSocket-Extensions
which can set a non-default window_bits
email.received matches on MIME EMAIL Received
This keyword maps to the EVE field email.received[]
It is a sticky buffer
Supports multiple buffer matching
Supports prefiltering

email.url matches on URLs extracted from an email
This keyword maps to the EVE field email.url[]

Remove the authors field as it is deprecated.
Update the repository page to the Suricata repository.
Remove the homepage, it can be found via the reposistory page.
As the "suricata" crate depends on htp, we need to publish htp to
crates.io first, however "htp" name is already taken. So rename "htp" to
"suricata-htp".
On a normal project where the Cargo.lock is checked in, it would be
normal to see an updated Cargo.lock in git status and the like. As we
use autoconf to generate this file, we should just copy it back to the
input file so we get the same convenience of seeing when it is
updated, which usually means it needs to be checked in.
However, to satisfy "make distcheck", only copy it if the input
template exists, if the input template does not exist we are in an out
of tree build.
ldap.responses.attribute_type matches on LDAP attribute type/description
This keyword maps the eve field ldap.responses[].search_result_entry.attributes[].type
It is a sticky buffer
Supports multiple buffer matching

ldap.request.attribute_type matches on LDAP attribute type/description
This keyword maps the following eve fields:
ldap.request.search_request.attributes[]
ldap.request.modify_request.changes[].modification.attribute_type
ldap.request.add_request.attributes[].name
ldap.request.compare_request.attribute_value_assertion.description
It is a sticky buffer

Move handling of FTP responses to Rust to improve support for FTP
keyword matching. Parsing the response line when encountered
simplifies multi-buffer matching and metadata output.
Issue: 4082
This module uses the sawp-pop3 crate to parse POP3 requests and responses
Features:
- eve logging
- events for parsable but non-RFC-compliant messages

Config:
Firewall rules are like normal rule, with some key differences.
They are loaded separate, and first, from:
```yaml
firewall-rule-path: /etc/suricata/firewall/
firewall-rule-files:
- fw.rules
```
Can also be loaded with --firewall-rules-exclusive: Mostly for QA purposes.
Allow -S with --firewall-rules-exclusive, so that firewall and threat detection
rules can be tested together.
Rules:
Differences with regular "threat detection" rules:
1. these rules are evaluated before threat detection rules
2. these rules are evaluated in the order as they appear in the rule file
3. currently only rules specifying an explicit hook at supported
a. as a consequence, no rules will be treated as (like) IP-only, PD-only or
DE-only
Require explicit action scope for firewall rules. Default policy is
drop for the firewall tables.
Actions:
New action "accept" is added to allow traffic in the filter tables.
New scope "accept:tx" is added to allow accepting a transaction.
Tables:
Rulesets are per table.
Table processing order: `packet:filter` -> `packet:td` -> `app:*:*` -> `app:td`.
Each of the tables has some unique properties:
`packet:filter`:
- default policy is `drop:packet`
- rules are process in order
- action scopes are explicit
- `drop` or `accept` is immediate
- `accept:hook` continues to `packet:td`
`packet:td`:
- default policy is `accept:hook`
- rules are ordered by IDS/IPS ordering logic
- action scopes are implicit
- actions are queued
- continues to `app:*:*` or `alert/action finalize`
`app:*:*`:
- default policy is `drop:flow`
- rules are process in order
- action scopes are explicit
- `drop` is immediate
- `accept` is conditional on possible `drop` from `packet:td`
- `accept:hook` continues to `app:td`, `accept:packet` or `accept:flow`
continues to `alert/action finalize`
`app:td`:
- default policy is `accept:hook`
- rules are ordered by IDS/IPS ordering logic
- action scopes are implicit
- actions are queued
- continues to `alert/action finalize`
Implementation:
During sigorder, split into packet:filter, app:*:* and general td.
Allow fw rules to work when in pass:flow mode. When firewall mode is enabled,
`pass:flow` will not skip the detection engine anymore, but instead
process the firewall rules and then apply the pass before inspecting threat
detect rules.
If we see a space-like character that is not space 0x20 in uri,
we set this event, even it the request line finished with a normal
space and protocol

Move enum OutputJsonLogDirection and struct
EveJsonTxLoggerRegistrationData to a public header user by rust
thanks to bindgen
Rename to use SC prefix on the way
And make EveJsonSimpleTxLogFunc use a const pointer to transaction
suricata.yaml output section for smb now parses a types list
and will restrict logging of transactions to these types.
By default, everything still gets logged
Remove unused rs_smb_log_json_request on the way

This sub-protocol inspects messages exchanged between postgresql backend
and frontend after a 'COPY TO STDOUT' has been processed.
Parses new messages:
- CopyOutResponse -- initiates copy-out mode/sub-protocol
- CopyData -- data transfer messages
- CopyDone -- signals that no more CopyData messages will be seen from
the sender for the current transaction
