Try to fix problem if balancing free client DCB and free session so that auth data is always available and client DCB is not freed until session is ready to be freed. Also fix problem in auth logic.

395cbdc103
Simplify handling of "client data" by having a pointer to it only in DCB and not in session structure. Change name of session->client to session->client_dcb for greater clarity. Temporary free of client data in DCB, to be moved to authenticator when it becomes a module. Fix incorrect name of listener_alloc.

Changes to improve robustness of SSL processing, separate it so far as possible from protocols. Separate the detailed mechanism of authentication from the MySQL protocol with a view to making it into a module later.
2016-02-15 09:29:07 +00:00
971d1d5de2
Redesign logic of SSL connections to work with status in client DCB instead of in the protocol. This eases the way to moving SSL logic out of a specific protocol (currently MySQL) so as to be available across any protocol. Also, some simplification.
2016-02-03 08:54:55 +00:00
05fa498dc0
Add an SSL header needed to support extra data in DCB.
2016-01-27 15:46:50 +00:00
8367d93746
Migrate SSL functionality out of service and into listener. Develop config handling accordingly, including making provision for SSL parameters in servers for future use in implementing SSL to backend servers. Some elements still to be tidied mainly in mysql_client.c - but that will be part of detaching the SSL authentication from the MySQL protocol.
2016-01-27 15:46:19 +00:00
e58148356d
Split off listener functionality and move SSL initiation from service to listener. Put GWPROTOCOL in its own header file.

Rearrange libraries and build files.
...
This is the first change in an attempt to arrange the linking so that
more errors are detected at link-time.
- All files in server/core but for gateway.c are linked to one shared
library called maxscale-common.
- The files log_manager/log_manager.cc and utils/skygw_utils.cc are
built into maxscale-common as well.
- MaxScale itself consists now only of gateway.c and is linked with
maxscale-common.
- All plugins link with maxscale-common.
- All executables link in addition with {EMBEDDED_LIB}.
After this change, the change (MXS-517) where query_classifier is the
only component that uses ${EMBEDDED_LIB} and the rest mysqlclient can
be made much cleaner.
After a few additional steps, all shared libraries can be linked with
the linker flags "-Wl,-z,defs", which directs the linker to resolve
all symbols. That will require that all shared libraries list all the
libraries they need, but will at the same time ensure that any
missing symbols are detected at link-time and not at run-time.

MXS-549: Change MaxScale's working directory on startup
...
MaxScale now changes the working directory to the log directory when it is
started. If this fails, the file system root is used instead.

Fixed idle session processing
...
The current implementation of idle connection timeouts is not safe. The sessions
are handled in a way which is not thread-safe and the checking is done from
a non-polling thread.
With this change, the checks for the session timeouts are done in one of the
polling threads in a thread-safe manner only if at least one service has enabled
the timing out of idle client connections.

Improved query canonicalization
...
The query does not need to be parsed for it to be canonicalized and the parsing
uses the PCRE2 library. The regular expressions were changed so that only one
call to the function which replaces literal unquoted values is made.
2016-01-11 17:08:03 +02:00
b01e8b2eec
Added utils library initialization function and improved replace_quoted
...
Currently the initialization function only prepares PCRE2 patterns for use.
Added the call to the new utils_init() function to MaxScale and all relevant
tests.
The replace_quoted now uses a shared PCRE2 pattern which should remove some
of the overhead of the function.
