Philippe Antoine b21acfbf21 http2: StreamIdReuse frame types exceptions 
Also handles better the state so as not to revert from
HTTP2StateHalfClosedClient to HTTP2StateDataServer and not
go to final HTTP2StateClosed

Philippe Antoine d57275fa64 protodetect: rerun probing parser if pattern matched 
If a pattern matches in the other direction, after
probing parser finished without finding a protocol,
we will rerun the probing parser, which will include
the newly protocol found by its pattern
 4 years ago
Philippe Antoine 5f348e9907 protodetect: runs probing parser on protocol found 
It a protocol is found in a first direction, we should run the
probing parser, even if it is not in the known ports.

That can happen for HTTP2, where client magic is detected,
then server probe can be run

Philippe Antoine 518e0e66cb applayer: fix a leak in protocol change 
TCPProtoDetect can either set f->alproto, change f->alstate
and return error.

When the original alstate gets freed, we shall set the pointer
to NULL, as it can get reused.

Shivani Bhardwaj 97c67cd5ce dcerpc: fix gap handling 
This patch addresses issues discovered by redmine ticket 3896. With the
approach of finding latest record, there was a chance that no record was
found at all and consumed + needed became input length.

e.g.
input_len = 1000
input = 01 05 00 02 00 03 a5 56 00 00 .....

There exists no |05 00| identifier in the rest of the record. After
having parsed |05 00|, there was a search for another record with the
leftover data. Current data length at this point would be 997. Since the
identifier was not found in the data, we calculate the consumed bytes at
this point i.e. consumed = current_data.len() - 1 which would be 996.
Needed bytes still stay at a constant of 2. So, consumed + needed = 996
+ 2 = 998 which is lesser than initial input length of 1000 and hence
the assertion fails.

There could be two fixes to this problem.
1. Finding the latest record but making use of the last found record in
   case no new record was found.
2. Always use the earliest record.

This patch takes the approach (2). It also makes sure that the gap and
current direction are the same.

Jeff Lucovsky c5ace81a27 log/eve: Rename fileinfo alert object to files 
This commit changes the name of the "fileinfo" array in the alert object
to "files" to better support legacy use of "fileinfo" in reporting and
elsewhere.

The "fileinfo" event type is not an array while the alert "fileinfo"
member was.

Jason Ish 69fffb2dc4 doc/userguide: include man page even when not including pdf 
Fix a mistake in Makefile.am where the man page was only being
added to the distribution if the PDF was also created. It should
be included even if the PDF cannot be included.

Shivani Bhardwaj 87617b200c doc/datasets: add info about memcap and hashsize 5 years ago
Shivani Bhardwaj 1286b0a8f1 datasets: parse defaults section from yaml 
Datasets can now have a global defaults setting in suricata.yaml. In
case the settings for memcap and hashsize are not find in the yaml or
rule, this shall be the fallback.

Example:

datasets:
  defaults:
    memcap: 100mb
    hashsize: 2048
  ua-seen:
    type: string
    load: datasets.csv
 5 years ago
Shivani Bhardwaj 5ac94fc407 datasets: allow memcap, hashsize be set via yaml or rule 
It is now possible to set the memcap and hashsize via suricata.yaml and
rules.

Rule example:

alert http any any -> any any (http.user_agent; dataset:isset,ua-seen,type string,load datasets.csv,memcap 100mb,hashsize 2048; sid:1;)

suricata.yaml example:

datasets:
  ua-seen:
    type: string
    load: datasets.csv
    memcap: 20mb
    hashsize: 2048
 5 years ago
Shivani Bhardwaj b2482d6c60 datasets: allow max possible memcap while loading 
While using the "load" option of datasets, it should be possible to load
any file from the disk, so set the limit to highest possible.

Philippe Antoine 547d6c2d78 applayer: pass parameter to StateAlloc 
This parameter is NULL or the pointer to the previous state
for the previous protocol in the case of a protocol change,
for instance from HTTP1 to HTTP2

This way, the new protocol can use the old protocol context.
For instance, HTTP2 mimicks the HTTP1 request, to have a HTTP2
transaction with both request and response
