Victor Julien efee458af8 stream: fix direction flags in corner case 
When a TCP DNS flow would start with a GAP on the TS side, the successful
protocol detection on the TC side would trigger 'opposing side' reassembly
and app-layer processing. In this case the stream flags would indicate the
wrong direction and the wrong parser would be called.

Jason Ish 8a643c893c detect/parse: allow for OK signature parsing errors 
The idea of an OK signature parsing error is an error that is
allowed to occur, but still lets test mode pass, unlike
silent errors which will still fail testing.

This is introduced to allow for app-layer event keywords to be
removed, but not have old rules fail out on this case. For example
the Rust DNS parser removes from DNS app-layer events that are
not used anymore.

To signal that an error is OK, -3 is returned. This also implies
silent.
 7 years ago
Jason Ish 947cfac62e detect/parse: softer error on unknown app-layer event 
On an unknown app-layer event, return -3 for "silent OK fail". A
warning will still be emitted, but its not considered a rule parse
error. This is to handle app-layer events being removed in a more
graceful manner for the user.

This allows -T to pass with an old app-layer events rule file
that may used removed app-layer event keywords.

Victor Julien 072c421e46 pcap/file: improve time handling 
This patch addresses two problems.

First, various parts of the engine, but most notably the flow manager (FM),
use a minimum of the time notion of the packet threads. This did not
however, take into account the scenario where one or more of these
threads would be inactive for prolonged times. This could lead to the
time used by the FM could get stale.

This is addressed by keeping track of the last time the per thread packet
timestamp was updated, and only considering it for the 'minimum' when it
is reasonably current.

Second, there was a minor race condition at start up, where the FM would
already inspect the hash table(s) while the packet threads weren't active
yet. Since FM gets the time from the packet threads, it would use a bogus
time of 0.

This is addressed by adding a wait loop to the start of the FM that waits
for 'time' to get ready.

Victor Julien ae4137937e pcap/file: fix race during pcap processing start 
A race condition during the start of pcap file processing could cause
missed alerts and logged events. This race happens between the packet
threads and the flow manager. It was observed on slower hardware, but in
theory could happen on any machine. It required the 'autofp' runmode.

In commit 6f560144c1 ("time: improve offline time handling") the logic
was added to make the flow manager use a minimum of all the packet threads
perception of time.

The race condition was that the flow manager may become active _before_
all of the packet threads have started processing packets and thus setting
their timestamp. The threads that had not yet initialized their timestamp
would not be considered when calculating the minimum.

As a result of this, older packets timestamps would not yet be registered.
This would give the Flow Manager a timestamp too far in the future. While
the FM was running, the packet processing would start and a flow would
be created. This flow would then immediately be considered 'timed out' by
the FM, due to the timestamp too far in the future.

In the observed case, the thread processing packet 1 from the pcap had not
yet started processing while other threads had already started. The FM was
also already active. Due to the timestamps in the pcap this meant that the
time the FM used was about 500 seconds in the future compared to packet 1.

This patch fixes the issue by initializing all of the threads timestamps
with the timestamp value of the first packet. This way the minimum will
always consider this timestamp.

Timo Sigurdsson 1262ecbde0 init: Fix dropping privileges in nflog runmode 
Using the run-as configuration option with the nflog capture method
results in the following error during the startup of suricata:
[ERRCODE: SC_ERR_NFLOG_BIND(248)] - nflog_bind_pf() for AF_INET failed

This is because SCDropMainThreadCaps does not have any capabilities
defined for the nflog runmode (unlike other runmodes). Therefore, apply
the same capabilities to the nflog runmode that are already defined for
the nfqueue runmode. This has been confirmed to allow suricata start
and drop its privileges in the nflog runmode.

Fixes redmine issue #3265.

Victor Julien f8aed4ce2d threading: change local packet queue logic 
Previously each 'TmSlot' had it's own packet queue that was passed
to the registered SlotFunc as an argument. This was used mostly for
tunnel packets by the decoders and by defrag.

This patch removes that in favor of a single queue in the ThreadVars:
decode_pq. This is the non-locked version of the queue as this is
only a temporary store for handling packets within a thread.

This patch removes the PacketQueue pointer argument from the API.
The new queue can be accessed directly through the ThreadVars
pointer.

Victor Julien 02004fa547 threading: remove per slot post_pq 
Use a single packet queue per thread for flow timeout packet
injection. The per slot queue was unused except for this use
case. Having a single queue makes the logic and implementation
simpler.

In case of 'autofp', the per thread packet queue will actually
use the threads input queue. For workers/single a dedicated
queue will be set up.

Rename TmThreadsSlotHandlePostPQs to TmThreadsHandleInjectedPackets
to reflect the changed logic.

Victor Julien 9d0976ea8a output/tx: split list of loggers per alproto 
This patch splits the list of loggers the tx logging walks into lists per
alproto. The list was getting longer with each eve addition. The result
was that for each tx we would have to loop through multiple loggers that
did not apply to this tx as it was for the wrong protocol.

Victor Julien 9f0294fadc stream: fix SYN_SENT RST/FIN injection 
RST injection during the SYN_SENT state could trick Suricata into marking
a session as CLOSED. The way this was done is: using invalid TSECR value
in RST+ACK packet. The ACK was needed to force Linux into considering the
TSECR value and compare it to the TSVAL from the SYN packet.

The second works only against Windows. The client would not use a TSVAL
but the RST packet would. Windows will reject this, but Suricata considered
the RST valid and triggered the CLOSED logic.

This patch addresses both. When the SYN packet used timestamp support
the timestamp of incoming packet is validated. Otherwise, packet responding
should not have a timestamp.
