hugepages: run hugepage check only on DPDK runmode and on Linux

Previous implementation allowed FreeBSD to enter into the hugepage
analysis. It then failed with an error message because hugepage/
NUMA node paths that are used in the codebase to retrieve info about
the system are not the same with the structure in Linux.

Additionally, the messages were logged on error level. It has been
demoted to info level because the whole hugepage analysis checkup is
only for informational purposes and does not affect Suricata operation.

The hugepage analysis and the hugepage snapshots are now limited to
only run in the DPDK runmode.

Lukas Sismis [Tue, 6 Feb 2024 10:38:19 +0000 (11:38 +0100)] 
tcp: do not assign TCP flags to pseudopackets

Previously pseudopackets were assigned with ACK flag which falsely turned
"SYN" flows to "SYN/ACK" flows when Suricata ran with raw content-matching
rules. The problem occured during the flow timeout or Suricata shutdown,
essentially, when the flow was being kicked out (with a pseudopacket).

When Suricata ran without raw content-matching rules (the ruleset did not
contain content matching keywords or it only contained keywords that are
app-layer content-matching) then raw stream reassembly tracking is turned off
(SignatureHasStreamContent()).
This in turn disabled a check in StreamNeedsReassembly() and the right edge
was not checked with the raw stream progress. In turn, it did not generate
a pseudopacket that would go through the detection engine. Suricata with
raw content-matching keywords would therefore on a flow with SYN packet only
return STREAM_HAS_UNPROCESSED_SEGMENTS_NEED_ONLY_DETECTION which would generate
the pseudopacket.

In Suricata versions <= 6.0.x, the flow output was correct because
only the commit 1bb6f44ff01363fa29488f1ae83b9368e33c2770 started to
differentiate the right edge calculation between the raw and application
layer streams. The older Suricata versions used only the application layer
right edge equation and therefore did not generate a pseudopacket.

17 months agomulti-tenant: fix loader dead lock 10442/head

multi-tenant: fix loader dead lock

A dead lock could occur at start up, where a loader thread would
get stuck on it's condition variable, while the main thread was
polling the loaders task results.

The vector to the dead lock is as follows:

main                         loader
DetectEngineMultiTenantSetup
-DetectLoaderSetupLoadTenant
--DetectLoaderQueueTask
---lock loader
---add task
---unlock loader
                        lock loader
                        check/exec tasks
                        unlock loader
---wake up threads
                        lock ctrl mutx
                        cond wait ctrl
                        unlock ctrl
-DetectLoadersSync
--lock loader
--check tasks
--unlock loader

Between the main thread unlocking the loader and waking up the
threads, it is possible that the loader has already moved ahead
but not yet entered its conditional wait. The main thread sends
its condition signal, but since the loader isn't yet waiting on
it the signal is ignored. Then when the loader does enter its
conditional wait, the signal is not sent again.

This patch updates the logic to send signals much more often.
It also makes sure that the signal is sent under lock, as the
API requires.

stats: Do not expand dots of tm_name

When an interface with dots is used, per worker stats are nested by the
dot-separated-components of the interface due to the usage of
OutputStats2Json().

Prevent this by using OutputStats2Json() on a per-thread specific object
and setting this object into the threads object using the
json_object_set_new() which won't do the dot expansion.

and checking the stats.

17 months agosmtp: avoid creating empty transaction
Philippe Antoine [Tue, 14 Nov 2023 20:51:37 +0000 (21:51 +0100)] 
smtp: avoid creating empty transaction

Ticket: 6477

So as to avoid ending up with too many empty transactions.

This happens when Suricata sees a DATA command in the current
transaction but did not have a confirmation response for it.
Then, if Suricata receives another DATA command, it will
create another new transaction, even if the previous one
is empty. And so, a malicious client can create many empty
transactions by just sending a repeated amount of DATA commands
without having a confirmation code for them.

Suricata cannot use state->current_command == SMTP_COMMAND_DATA
to prevent this attack and needs to resort to a new boolean
is_data because the malicious client may send another dummy command
after each DATA command.

This patch leaves only one call to SMTPTransactionCreate

http2: handle reassembly for continuation frames

Ticket: 5926

HTTP2 continuation frames are defined in RFC 9113.
They allow header blocks to be split over multiple HTTP2 frames.
For Suricata to process correctly these header blocks, it
must do the reassembly of the payload of these HTTP2 frames.
Otherwise, we get incomplete decoding for headers names and/or
values while decoding a single frame.

Design is to add a field to the HTTP2 state, as the RFC states that
these continuation frames form a discrete unit :
> Field blocks MUST be transmitted as a contiguous sequence of frames,
> with no interleaved frames of any other type or from any other stream.
So, we do not have to duplicate this reassembly field per stream id.

Another design choice is to wait for the reassembly to be complete
before doing any decoding, to avoid quadratic complexity on partially
decoding of the data.

When a TCP flow packet has not led to app-layer updates,
it is useless to run DetectRunTx, as there cannot be new
matches.

This happens for instance, when one side sends in a row multiple

Doing so requires to move up the call to

case where the transaction was not updated.

detect/transform: Clarify transformation validation

Issue: 6439

Clarify the transform validation step. When a transform indicates that
the content/byte-array is not compatible, validation will stop.

Content is incompatible is some cases -- e.g., following the
to_lowercase transform with content containing uppercase characters.
An alert is not possible since the content contains uppercase and the
transform has converted the buffer into all lowercase.
