* source4/smbd: refactor the process model for preforkGary Lockyer2017-10-191-6/+9
| | | | | | | | | | | | | | | | | | Refactor the process model code to allow the addition of a prefork process model. - Add a process context to contain process model specific state - Add a service details structure to allow service to indicate which process model options they can support. In the new code the services advertise the features they support to the process model. The process model context is plumbed through to allow the process model to keep track of the supported options, and any state the process model may require.

* source4 smbd: remove global control pipe from process_standard.Gary Lockyer2017-09-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The standard model uses a pipe to signal the worker processes spawned on accept that the controlling process has terminated and that they should shut down. This pipe is currently a static global variable in process_standard.c. This patch replaces that global pipe with a file descriptor passed into the process model init functions, giving a single mechanism across all process models. This paves the way for the addition of a pre-fork process model. Ensuring that the correct file descriptors are closed, is difficult so it is best do this only once rather than require the process models to do this individually. Notes on debugging pipe ownership: Add code to log the process id and the file descriptor of the writeable pipe. run: lsof | grep FIFO | grep samba | grep <process id> this will produce lines like: samba 25624 him 4w FIFO 0,10 0t0 472206 pipe where: 4w is the file descriptor and mode and the number to the left of "pipe" is the pipe id. then: lsof | grep FIFO | grep samba | grep <pipe id> This will display all the processes with the pipe open and the mode only the smbd master process should have it open in write mode.

* Remaining changes to implement the prefork process modelAndrew Bartlett2008-02-041-1/+2
| | | | | | | | | | | | | | | | | | | To use, run 'smbd -M prefork' By default, only the smb service is preforked. 4 children are created, and all listen for new connections. The Linux Kernel 'wake one' behaviour should ensure that only one is given the oportunity to accept. We need to look into the ideal number of worker children, as well as load balancing behaviours. To change, set: prefork children : smb = 6 valid service names (smb in this example) match those in 'server services'.

* r5102: This is a major simplification of the logic for controlling top levelAndrew Tridgell2007-10-101-22/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | servers in smbd. The old code still contained a fairly bit of legacy from the time when smbd was only handling SMB connection. The new code gets rid of all of the smb_server specific code in smbd/, and creates a much simpler infrastructures for new server code. Major changes include: - simplified the process model code a lot. - got rid of the top level server and service structures completely. The top level context is now the event_context. This got rid of service.h and server.h completely (they were the most confusing parts of the old code) - added service_stream.[ch] for the helper functions that are specific to stream type services (services that handle streams, and use a logically separate process per connection) - got rid of the builtin idle_handler code in the service logic, as none of the servers were using it, and it can easily be handled by a server in future by adding its own timed_event to the event context. - fixed some major memory leaks in the rpc server code. - added registration of servers, rather than hard coding our list of possible servers. This allows for servers as modules in the future. - temporarily disabled the winbind code until I add the helper functions for that type of server - added error checking on service startup. If a configured server fails to startup then smbd doesn't startup. - cleaned up the command line handling in smbd, removing unused options (This used to be commit cf6a46c3cbde7b1eb1b86bd3882b953a2de3a42e)

I'll add datagram services later when we whave support for datagram sockets in lib/socket/ see the next commit as an example for service_task's metze (This used to be commit d5fa02746c6569b09b6e05785642da2fad3ba3e0)

| | | | | | | | | | | | | deferred reply is short-circuited immediately when the file is closed by another user, allowing it to be opened by the waiting user. - added a sane set of timeval manipulation routines - converted all the events code and code that uses it to use struct timeval instead of time_t, which allows for microsecond resolution instead of 1 second resolution. This was needed for doing the pvfs deferred open code, and is why the patch is so big. (This used to be commit 0d51511d408d91eb5f68a35e980e0875299b1831)

* r1486: commit the start of the generic server infastructureStefan Metzmacher2007-10-101-10/+7
| | | | | | | | | | | | | | | | | | | the idea is to have services as modules (smb, dcerpc, swat, ...) the process_model don't know about the service it self anymore. TODO: - the smbsrv should use the smbsrv_send function - the service subsystem init should be done like for other modules - we need to have a generic socket subsystem, which handle stream, datagram, and virtuell other sockets( e.g. for the ntvfs_ipc module to connect to the dcerpc server , or for smb or dcerpc or whatever to connect to a server wide auth service) - and other fixes...
