Prior to this change, both --disable_database=false and --database_path had to
be specified together. Now, if the user specifies --database_path the database
is enabled automatically.
This includes a minor SDK refactor as it move quite a few specialized
functions and facilities from core.h into system.h. There was a breaking point
for needing to frequently update core includes.
The new logger systemLog function allows a call site to bypass logging config
and write a line to the OS logger (aka syslog).
This commit bumps the third-party SQLite to the 3.14.0 pre-release (18:59).
With 3.14.0 the LIKE and EQUALS constraint operators may be mixed within a
query. Previously these would fail to produce a valid set.
As part of the support, each virtual table should choose to bypass rowid-based
deduplication using the new "WITHOUT ROWID" create table epilog. This will
be appended to the schema if the table defines a PRIMARY KEY using index=True.
* Implemented filesystem operations abstraction code
* Added filesystem operations abstraction unit tests
* Modified CMake configurations to support the building of the abstraction code and unit tests
This changes several initialization steps:
- The daemon (and shell, though not needed) have a new --ephemeral flag.
- Events are now disabled in the shell by default, use --nodisable_events to
re-enable.
- RocksDB-based backing storage is now disabled in the shell by default.
The --ephemeral flag for the daemon is disabled by default and will allow
skipping configuration and database path sanity, and skipping pidfile checks.
This is intended to be used when debugging or monitoring the daemon process.
To make the RocksDB backing storage feature usage very clear we introduce a new
flag: --disable_database. The shell sets this to true unless overridden in
a flagfile or via command line arguments.
Table options includes a change to the Registry::call API for TablePlugins.
When requesting route information or the 'columns' action, a new 'op' key is included.
Integrated process abstraction code into more locations
Defined new macros for abstracting across various platforms
Added GLOG_NO_ABBREVIATED_SEVERITIES for glog to support Windows
Fixed some minor CMake issues involving thrift
Updated gflags package; reflecting change in provision script
Preparing CMake config files for WIN32 support
When selecting UUID as the host identifier the client follows:
- If host_identifier is set to hostname, return the hostname
- If UUID check a static UUID container
- If empty request the UUID from the backing storage, RocksDB
- If empty use the Apple hardware UUID or generate a UUID
- If the Apple UUID request fails generate a UUID
When no UUID is available in the backing store save the new UUID.
Added Windows support for process operations.
Added unit tests for process abstraction code for POSIX and Windows.
Modified CMake config files to support building the new code and unit tests.
This adds a new optimization feature that allows expensive tables to cache
their results between JOINs. Consider JOINing a list of open sockets, for each
process, then requesting to hash each process path. This query may hash
the same path multiple times.
Within-query caching allows the hash table to respond with the previous
result of the hash request as long as the requested computation was the result
of a single query. Subsequent queries will perform subsequent hashing.
Beginning in version 1.8.0 all time uses will converge on an osquery-provided
getUnixTime() API call that returns, by default, UNIX time integers converted
to UTC/GMT. The 'time' table will respond with the parsed time for the
configuration. If the timezone is not UTC then osquery is using localtime.
This configuration option will affect the 'unix_time' response in the 'time'
table. Because of this configurable-effect the table is extended to include
'local_time' which is always the system local UNIX time.
2. Introduce a SQLite-based database plugin
3. Refactor database usage to include local 'fast-calls'
4. Introduce an 'ephemeral' database plugin for testing (like a mock)
