This is to avoid the tx logging code that doesn't support LoggerId
values over 31 at this time. The simplest fix for now is to just have
all JSON (eve) loggers use the same ID.
DNP3 is left as-is for now as it needs some extra support in the parser.
The first change was to have CreateEveHeader add the common options
as this was left out in a few loggers. While update all the loggers
that use CreateEveHeader, remove redundant code, in particular
from loggers that don't need to use their own context but
can use the generic one.
This commit modifies the JSON loggers with changes necessary to support
multi-threaded EVE output.
Each "thread-init" function sets up the per-thread log file context for
subsequent calls to the JSON output to buffer function.
Currently alert logging relies on the ability to change existing
values in the json_t structure to overwrite addresses with xff
data. This feature is also used for the "target" logging.
As we can't do this with JsonBuilder, create a new struct to
hold the 5 tuple, with the values swapped as needed, and
overwritten with XFF data if needed. This struct will now
be used to write out the 5 tuple, as well as cache the information
for log fields to be written out later on in the log path.
The new OutputInitResult is a struct return type that allows
logger init functions to return a NULL context without
raising error.
Instead of returning NULL to signal error, the "ok" field will
be set to false. If ok, but the ctx is NULL, then silently
move on to the next logger.
Use case: multiple versions of a specific logger, and one
implementation decides the configuration is not for that
implemenation. It can return NULL, ok.
Many were using AlertJsonThread instead of OutputJsonCtx,
but as the datatypes were similar enough no harm was done.
Now that they are using their proper datatype, removed
AlertJsonThread from output.h as its no longer used.
Since the parser now also does nfs2, the name nfs3 became confusing.
As it's still in beta, we can rename so this patch renames all 'nfs3'
logic to simply 'nfs'.
