To simplify meta data handling inside the intel framework and avoid
duplicate insertion of meta data on update, meta data is stored in a
table indexed by meta data source.
By addind debug output to Intel::insert() the testcase reveals that
updating an intel item will cause its metadata to be inserted again,
without the old being deleted.
* 'topic/johanna/filter_subnet_table' of https://github.com/J-Gras/bro:
Fixed &read_expire for subnet-indexed tables
Added &read_expire testcase for subnet tables
Includes a bit of refactoring of commit code & code related to the
feature.
This bif works similar to the matching_subnet bif. The difference is
that, instead of returning a vector of the subnets that match, we return
a filtered view of the original set/table only containing the changed
subnets.
This commit also fixes a small bug in TableVal::UpdateTimestamp
(ReadOperation only has to be called when LoggingAccess() is true).

The server-reported file size was being collected poorly and if
a file name had a number in it, that was reported as the file
size instead of the actual size.
A new test is included to avoid reintroducing the problem.
Adds the functions
NetControl::find_rules_addr and NetControl::fund_rules_subnet
which return a vector containing all rules affecting a certain IP or
subnet.
This has no user-facing changes. It makes the internal handling of rules
much easier (no crazy duplicate rules in case our rules are added to
several backends).
It also fixes several open ends and small bugs in the process.
- Actually get the path into the smb_files.log now.
- When a share root is having the "create" message used on it,
instead of giving a null file name, now give a special
indicator of "<share_root>".
- Update test baselines.
I still haven't figured out exactly how to parse create contexts
and create reqeusts are an important message type. Right
now the create context sections are just not parsed or used.
This does not really have many user-facing changes. The one big change
is that users now should initialize plugins in the
NetControl::init()
event instead of bro_init.
Once all plugins finished initializing and the NetControl framework
starts operations, the NetControl::init_done() event is raised.
Rules that are sent to NetControl before the plugins have finished
initializing are ignored - this is important when several plugins that
require external connections have to be initialized at the beginning.
Without this delay, rules could end up at the wrong plugin.
The hook name is NetControl::acld_rule_policy and allows the
modification of acld rules before they are sent out to the network.
This allows, e.g. network policies to use nullzero instead of drop in
certain circumstances.
* 'patch-4' of https://github.com/aeppert/bro:
(BIT-1545) Add "disable_analyzer_after_detection" en lieu of "skip_processing_after_detection"
I also removed the old disable_analyzer_after_detection option
completely - if someone wants that, they can just catch the event
themselves and call skip_further_processing.
I also adjusted the ssh test case to contain conn.log to prevent
re-addition of this problem in the future.
