Simplify and clean up header buffer management. The code was designed
to track buffers for several transactions in parallel, from when the
detection engine wasn't aware of transactions.
For http.start and http.header_names use generic mpm and inspect
functions.
If an HTTP2 file was within only ont DATA frame, the filetracker
would open it and close it in the same call, preventing the
firther call to incr_files_opened
Also includes rustfmt again for all HTTP2 files
After a file has been closed (CLOSE, COMMIT command or EOF/SYNC part of
READ/WRITE data block) mark it as such so that new file commands on that
file do not reuse the transaction.
When a file transfer is completed it will be flagged as such and not be
found anymore by the NFSState::get_file_tx_by_handle() method. This forces
a new transaction to be created.
Storing too early can lead to files being considered TRUNCATED if the
TCP state is not yet CLOSED when logging is triggered. This has been
observed with FTP-DATA and might also be an issue with simple HTTP.
If one of the ppp peers sends a packet with an acknowledge flag,
the ppp payload will be empty and DecodePPP will return TM_ECODE_FAILED.
To handle this case, the packet_length field in the GRE extended header (https://tools.ietf.org/html/rfc2637#section-4.1) is used.
DecodeGRE no longer tries to parse PPP payload if packet_length is zero.
Add a bundle.sh script to bundle the requirements of libhtp
and suricata-update. This uses a Python like requirements.txt
file to specify the URL to download for libhtp and suricata-update.
Add generation of wrapper functions for get_event_info
and get_event_info_by_id to the derive macro. Eliminates
the need for the wrapper method to be created by the parser
author.
Provide generic functions for get_event_info and
get_event_info_by_id. These functions can be used by any app-layer
event enum that implements AppLayerEvent.
Unfortunately the parser registration cannot use these functions
directly as generic functions cannot be #[no_mangle]. So they
do need small extern "C" wrappers around them.
