Update all deps with cargo update. Additionally, apply the updated
versions to the Cargo.toml, which while not stricly required, does
make it more clear what the version in use is.
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".
This module uses the sawp-pop3 crate to parse POP3 requests and responses
Features:
- eve logging
- events for parsable but non-RFC-compliant messages

There are a lot of changes here, which are described below.
In general these changes are renaming constants to conform to the
libhtp-rs versions (which are generated by cbindgen); making all htp
types opaque and changing struct->member references to
htp_struct_member() function calls; and a handful of changes to offload
functionality onto libhtp-rs from suricata, such as URI normalization
and transaction cleanup.
Functions introduced to handle opaque htp_tx_t:
- tx->parsed_uri => htp_tx_parsed_uri(tx)
- tx->parsed_uri->path => htp_uri_path(htp_tx_parsed_uri(tx)
- tx->parsed_uri->hostname => htp_uri_hostname(htp_tx_parsed_uri(tx))
- htp_tx_get_user_data() => htp_tx_user_data(tx)
- htp_tx_is_http_2_upgrade(tx) convenience function introduced to detect response status 101
and “Upgrade: h2c" header.
Functions introduced to handle opaque htp_tx_data_t:
- d->len => htp_tx_data_len()
- d->data => htp_tx_data_data()
- htp_tx_data_tx(data) function to get the htp_tx_t from the htp_tx_data_t
- htp_tx_data_is_empty(data) convenience function introduced to test if the data is empty.
Other changes:
Build libhtp-rs as a crate inside rust. Update autoconf to no longer
use libhtp as an external dependency. Remove HAVE_HTP feature defines
since they are no longer needed.
Make function arguments and return values const where possible
htp_tx_destroy(tx) will now free an incomplete transaction
htp_time_t replaced with standard struct timeval
Callbacks from libhtp now provide the htp_connp_t and the htp_tx_data_t
as separate arguments. This means the connection parser is no longer
fetched from the transaction inside callbacks.
SCHTPGenerateNormalizedUri() functionality moved inside libhtp-rs, which
now provides normalized URI values.
The normalized URI is available with accessor function: htp_tx_normalized_uri()
Configuration settings added to control the behaviour of the URI normalization:
- htp_config_set_normalized_uri_include_all()
- htp_config_set_plusspace_decode()
- htp_config_set_convert_lowercase()
- htp_config_set_double_decode_normalized_query()
- htp_config_set_double_decode_normalized_path()
- htp_config_set_backslash_convert_slashes()
- htp_config_set_bestfit_replacement_byte()
- htp_config_set_convert_lowercase()
- htp_config_set_nul_encoded_terminates()
- htp_config_set_nul_raw_terminates()
- htp_config_set_path_separators_compress()
- htp_config_set_path_separators_decode()
- htp_config_set_u_encoding_decode()
- htp_config_set_url_encoding_invalid_handling()
- htp_config_set_utf8_convert_bestfit()
- htp_config_set_normalized_uri_include_all()
- htp_config_set_plusspace_decode()
Constants related to configuring uri normalization:
- HTP_URL_DECODE_PRESERVE_PERCENT => HTP_URL_ENCODING_HANDLING_PRESERVE_PERCENT
- HTP_URL_DECODE_REMOVE_PERCENT => HTP_URL_ENCODING_HANDLING_REMOVE_PERCENT
- HTP_URL_DECODE_PROCESS_INVALID => HTP_URL_ENCODING_HANDLING_PROCESS_INVALID
htp_config_set_field_limits(soft_limit, hard_limit) changed to
htp_config_set_field_limit(limit) because libhtp didn't implement soft
limits.
libhtp logging API updated to provide HTP_LOG_CODE constants along with
the message. This eliminates the need to perform string matching on
message text to map log messages to HTTP_DECODER_EVENT values, and the
HTP_LOG_CODE values can be used directly. In support of this,
HTP_DECODER_EVENT values are mapped to their corresponding HTP_LOG_CODE
values.
New log events to describe additional anomalies:
HTP_LOG_CODE_REQUEST_TOO_MANY_LZMA_LAYERS
HTP_LOG_CODE_RESPONSE_TOO_MANY_LZMA_LAYERS
HTP_LOG_CODE_PROTOCOL_CONTAINS_EXTRA_DATA
HTP_LOG_CODE_CONTENT_LENGTH_EXTRA_DATA_START
HTP_LOG_CODE_CONTENT_LENGTH_EXTRA_DATA_END
HTP_LOG_CODE_SWITCHING_PROTO_WITH_CONTENT_LENGTH
HTP_LOG_CODE_DEFORMED_EOL
HTP_LOG_CODE_PARSER_STATE_ERROR
HTP_LOG_CODE_MISSING_OUTBOUND_TRANSACTION_DATA
HTP_LOG_CODE_MISSING_INBOUND_TRANSACTION_DATA
HTP_LOG_CODE_ZERO_LENGTH_DATA_CHUNKS
HTP_LOG_CODE_REQUEST_LINE_UNKNOWN_METHOD
HTP_LOG_CODE_REQUEST_LINE_UNKNOWN_METHOD_NO_PROTOCOL
HTP_LOG_CODE_REQUEST_LINE_UNKNOWN_METHOD_INVALID_PROTOCOL
HTP_LOG_CODE_REQUEST_LINE_NO_PROTOCOL
HTP_LOG_CODE_RESPONSE_LINE_INVALID_PROTOCOL
HTP_LOG_CODE_RESPONSE_LINE_INVALID_RESPONSE_STATUS
HTP_LOG_CODE_RESPONSE_BODY_INTERNAL_ERROR
HTP_LOG_CODE_REQUEST_BODY_DATA_CALLBACK_ERROR
HTP_LOG_CODE_RESPONSE_INVALID_EMPTY_NAME
HTP_LOG_CODE_REQUEST_INVALID_EMPTY_NAME
HTP_LOG_CODE_RESPONSE_INVALID_LWS_AFTER_NAME
HTP_LOG_CODE_RESPONSE_HEADER_NAME_NOT_TOKEN
HTP_LOG_CODE_REQUEST_INVALID_LWS_AFTER_NAME
HTP_LOG_CODE_LZMA_DECOMPRESSION_DISABLED
HTP_LOG_CODE_CONNECTION_ALREADY_OPEN
HTP_LOG_CODE_COMPRESSION_BOMB_DOUBLE_LZMA
HTP_LOG_CODE_INVALID_CONTENT_ENCODING
HTP_LOG_CODE_INVALID_GAP
HTP_LOG_CODE_ERROR
The new htp_log API supports consuming log messages more easily than
walking a list and tracking the current offset. Internally, libhtp-rs
now provides log messages as a queue of htp_log_t, which means the
application can simply call htp_conn_next_log() to fetch the next log
message until the queue is empty. Once the application is done with a
log message, they can call htp_log_free() to dispose of it.
Functions supporting htp_log_t:
htp_conn_next_log(conn) - Get the next log message
htp_log_message(log) - To get the text of the message
htp_log_code(log) - To get the HTP_LOG_CODE value
htp_log_free(log) - To free the htp_log_t
Follow Rust convention of using a "sys" crate for bindings to C
functions. The bindings don't exist yet, but will be generated by
bindgen and put into this crate.

This prevents the clippy warning:
508 | #[derive(FromPrimitive, Debug)]
| ^------------
| |
| `FromPrimitive` is not local
| move the `impl` block outside of this constant `_IMPL_NUM_FromPrimitive_FOR_IsakmpPayloadType`
509 | pub enum IsakmpPayloadType {
| ----------------- `IsakmpPayloadType` is not local
|
= note: the derive macro `FromPrimitive` defines the non-local `impl`, and may need to be changed
= note: the derive macro `FromPrimitive` may come from an old version of the `num_derive` crate, try updating your dependency with `cargo update -p num_derive`
= note: an `impl` is never scoped, even when it is nested inside an item, as it may impact type checking outside of that item, which can be the case if neither the trait or the self type are at the same nesting level as the `impl`
= note: items in an anonymous const item (`const _: () = { ... }`) are treated as in the same scope as the anonymous const's declaration for the purpose of this lint
= note: this warning originates in the derive macro `FromPrimitive` (in Nightly builds, run with -Z macro-backtrace for more info)
To ensure that all calls to cargo use the same environment variables,
put the environment variables in CARGO_ENV so every call to cargo can
easily use the same vars.
The Cargo build system is smarter than make, it can detect a change in
an environment variable that affects the build, and the setting of
SURICATA_LUA_SYS_HEADER_DST changing could cause a rebuild.
Also update suricata-lua-sys, which is smarter about copying headers. It
will only copy if the destination does not exist, or the source header
is newer than the target, which can also prevent unnecessary rebuilds.
This is mainly to fix an issue where subsequent builds may fail,
especially when running an editor with a LSP enabled:
Update lua crate to 0.1.0-alpha.5. This update will force a rewrite of
the headers if the env var SURICATA_LUA_SYS_HEADER_DST changes. This
fixes the issue where the headers may not be written.
The cause is that Rust dependencies are cached, and if your editor is
using rust-analyzer, it might cache the build without this var being
set, so these headers are not available to Suricata. This crate update
forces the re-run of the Lua build.rs if this env var changes, fixing
this issue.
This crate lets us instruct it where to copy the header files instead
of our Makefile trying to find the correct ones and copying them into
place.
Can prevent the simultaneous copy errors sometimes seen on a make
without a clean.
base64 crate is updated to the latest version 0.22.1. This came with
several API changes which are applied to the code. The old calls have
been replaced with the newer calls.
This was done following the availability of better fns to directly
decode into slices/vectors as needed and also that previous version was
too old.
Along with this change, update the Cargo.lock.in to reflect all changes
in the package versions.
Task 7219
Time locked to 0.3.20 to guarantee MSRV of 1.63.
Update snmp-parser to 0.10.0.
Update asn1-rs to 0.6.1.
Update kerberos-parser to 0.8.0.
Update x509-parser 0.16.0.
Update der-parser to 9.0.0.
Remove specific use of der-parser 6.
Ticket: #6817.
Ticket: #6818.
Minimal modifications required on the Suricata side, mainly for fields
becoming private and needing an accessor instead.
Note: As the kerberos parser still depends on der-parser 6.0, we still
have to depend on that so it is depended on, but renamed to
der-parser6. There is not an udpated kerberos-parser yet that uses
der-parser 8.2.0.
Ticket: #5991
Updating snmp-parser required directly depending on the asn1-rs crate
for the Oid type, as snmp-parser does not re-export this type anymore.
Ticket: #5992
Cargo.lock has to be provided as template, Cargo.lock.in so it can
live beside Cargo.lock in out of tree automake builds, like distcheck.
This will pin Rust dependencies even for git builds, updating
Cargo.lock will now be a manual process that we'll have to take care
of periodically.
