This will remove the use of current time for syslog.time and introduce
a new column called 'datetime'.
Events now uses an "optimize_id" alongside "optimize" to prevent returning
colliding events added within the same second as the previous genTable call.
This commit adds an event-based virtual table implementation for
querying the linux syslog. It introduces an event publisher that
attaches to a named pipe to ingest CSV formatted syslog forwarded from
rsyslogd. An event subscriber/virtual table makes these log lines
available for queries. Currently, no additional processing is done on
the input data besides parsing.
Using this table requires a properly configured rsyslogd. Documentation
for this configuration is forthcoming in the wiki.
The refactor of config/packs was initiated because event subscribers needed
a method for toggling `::init` based on some configurable option. In the case
of auditd, turning on the support with `--disable_audit=false` used to start
auditing the EXECVE syscall. It was understandable that this would cause
latency based on the number of processes executing per measure of time.
A new `socket_events` table will do the same but for `bind` and `connect`. These
are less-obvious and for now, require a scan of /proc for socket tuples. In the
future this file descriptor to socket tuple will be faster.
This infomation is primarily related to the performance of processor
cores. The information given constitutes only a small portion of
the information in the model specific register, but this table
has been designed so that more information may easily be added.
The table requires osquery be run as the root, and that the msr
kernel module is loaded. The table reads the msr data from /dev
1. Example queries will run with an (optional) integration test.
2. Fix bad accesses with OS X package BOMs
3. Move spec files from ./osquery/tables/specs to ./specs
4. Remove server parsers (netlib) from client builds.
