Philippe Antoine 6663246563 parser: make rust probing parsers optional 7 years ago
Victor Julien f68c255f09 nfs: implement post-GAP transaction cleanup 
Close all prior transactions in the direction of the GAP, except the
file xfers. Those use their own logic described below.

After a GAP all normal transactions are closed. File transactions
are left open as they can handle GAPs in principle. However, the
GAP might have contained the closing of a file and therefore it
may remain active until the end of the flow.

This patch introduces a time based heuristic for these transactions.
After the GAP all file transactions are stamped with the current
timestamp. If 60 seconds later a file has seen no update, its marked
as closed.

This is meant to fix resource starvation issues observed in long
running SMB sessions where packet loss was causing GAPs. Due to the
similarity of the NFS and SMB parsers, this issue is fixed for NFS
as well in this patch.

Bug #3424.
Bug #3425.

Victor Julien 40fe29de96 smb1: fix 'event' txs not getting closed

we would not close it.

Victor Julien f9155aa121 files: simplify pruning logic 
Since ebcc4db84a the flow worker runs
file pruning after parsing, detection and loging. This means we can
simplify the pruning logic. If a file is in state >= CLOSED, we can
prune it. Detection and outputs will have had a final chance to
process it.

Remove the calls to the pruning code from Rust. They are no longer
needed.

Shivani Bhardwaj 6d39f6fd7d rust: Fix deprecation warnings 
Fix the following warnings by compiler,
(1) warning: use of deprecated item 'take_until_s': Please use `take_until` instead
(2) warning: `...` range patterns are deprecated

For the second warning, the builtin lint
"ellipsis_inclusive_range_pattern" has been added which causes the
following warning to show up with rustc 1.24.

warning: unknown lint: `ellipsis_inclusive_range_patterns`
  --> /home/travis/build/OISF/suricata/suricata-5.0.0-dev/rust/src/lib.rs:18:10

18 | #![allow(ellipsis_inclusive_range_patterns)]
   |          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: #[warn(unknown_lints)] on by default

Since there is no other way to fix this, the above warning shall stay.
We need to take care of modifying this if and when the support for 1.24
as MSRV is dropped.
