2008-02-04Remaining changes to implement the prefork process modelAndrew Bartlett1-5/+6
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'.

2007-10-10r19604: This is a massive commit, and I appologise in advance for it's size.Andrew Bartlett1-7/+0
This merges Samba4 with lorikeet-heimdal, which itself has been tracking Heimdal CVS for the past couple of weeks. This is such a big change because Heimdal reorganised it's internal structures, with the mechglue merge, and because many of our 'wishes' have been granted: we now have DCE_STYLE GSSAPI, send_to_kdc hooks and many other features merged into the mainline code. We have adapted to upstream's choice of API in these cases. In gensec_gssapi and gensec_krb5, we either expect a valid PAC, or NO PAC. This matches windows behavour. We also have an option to require the PAC to be present (which allows us to automate the testing of this code). This also includes a restructure of how the kerberos dependencies are handled, due to the fallout of the merge. Andrew Bartlett (This used to be commit 4826f1735197c2a471d771495e6d4c1051b4c471)

the old event context in the standard process modal child. Andrew Bartlett (This used to be commit 0f52a9ab071c181c7f764adc8be83e162e649931)
2007-10-10r10920: in case of a accept() failure just failing and trying again is noAndrew Tridgell1-0/+3
good, as it is probably a resource constraint, so if we just try again we will spin (as the incoming socket will still be readable). Using a sleep(1) solves this by throtting smbd until the resource constraint goes away. if the resource constraint doesn't go away, then at least smbd won't be spinning chewing cpu (This used to be commit 7a5a9da477186b5e4fdb34ec64cc97915de4fd8e)
2007-10-10r5298: - got rid of pstring.h from includes.h. This at least makes it a bitAndrew Tridgell1-0/+1
less likely that anyone will use pstring for new code - got rid of winbind_client.h from includes.h. This one triggered a huge change, as winbind_client.h was including system/filesys.h and defining the old uint32 and uint16 types, as well as its own pstring and fstring. (This used to be commit 9db6c79e902ec538108d6b7d3324039aabe1704f)
2007-10-10r5296: - only include the tdb headers where they are neededAndrew Tridgell1-0/+1
- removed the u32 hack in events.c as I think this was only needed as tdb.h defines u32. Metze, can you check that this hack is indeed no longer needed on your suse system? (This used to be commit 6f79432fe656164d4770dbce114a30dda5e7bf9a)
2007-10-10r5197: moved events code to lib/events/ (suggestion from metze)Andrew Tridgell1-1/+1

2007-10-10r5104: - added support for task based servers. These are servers that withinAndrew Tridgell1-4/+54
themselves are run as a single process, but run as a child of the main process when smbd is run in the standard model, and run as part of the main process when in the single mode. - rewrote the winbind template code to use the new task services. Also fixed the packet queueing - got rid of event_context_merge() as it is no longer needed (This used to be commit 339964a596689278d2138cff05d7d444798a3504)
2007-10-10r5102: This is a major simplification of the logic for controlling top levelAndrew Tridgell1-119/+40
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)
2007-10-10r4728: split up server_services into:Stefan Metzmacher1-27/+88
- stream_socket services the smb, ldap and rpc service which sets up a srtam socket end then waits for connections and - task services which this you can create a seperate task that do something (this is also going through the process_model subsystem so with -M standard a new process for this created with -M thread a new thread ... 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)
2007-10-10r3737: - Get rid of the register_subsystem() and register_backend() functions.Jelmer Vernooij1-1/+1
- Re-disable tdbtool (it was building fine on my Debian box but other machines were having problems) (This used to be commit 0d7bb2c40b7a9ed59df3f8944133ea562697e814)
2007-10-10r3507: - added deferred replies on sharing violation in pvfs open. TheAndrew Tridgell1-1/+1
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)

ioctl.h) (This used to be commit b97e395c814762024336c1cf4d7c25be8da5813a)
2007-10-10r3356: in the standard process model we need to make sure we close allAndrew Tridgell1-2/+7
listening sockets after the fork to prevent the child still listening on incoming requests. I have also added an optimisation where we use dup()/close() to lower the file descriptor number of the new socket to the lowest possible after closing our listening sockets. This keeps the max fd num passed to select() low, which makes a difference to the speed of select(). (This used to be commit f2a9bbc317ba86ebe87c3ca27a3a0192de91014d)
2007-10-10r3314: added a option "socket:testnonblock" to the generic socket code. IfAndrew Tridgell1-1/+1
you set this option (either on the command line using --option or in smb.conf) then every socket recv or send will return short by random amounts. This allows you to test that the non-blocking socket logic in your code works correctly. I also removed the flags argument to socket_accept(), and instead made the new socket inherit the flags of the old socket, which makes more sense to me.

2007-10-10r2654: fixed some more server memory leaks. We are now down to a single leakAndrew Tridgell1-0/+4
of 16 bytes, caused by the 16 byte data_blob in the smb_signing code. (This used to be commit 2f1b788e09686e065d22f621f5c0c585192c6740)
2007-10-10r2648: - use a destructor on struct server_connection to simplify theAndrew Tridgell1-9/+1
connection termination cleanup, and to ensure that the event contexts are properly removed for every process model - gave auth_context the new talloc treatment, which removes another source of memory leaks. (This used to be commit 230e1cd777b0fba82dffcbd656cfa23c155d0560)

2007-10-10r1498: (merge from 3.0)Andrew Bartlett1-0/+4
Rework our random number generation system. On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork(). For other systems, we now only re-seed after a fork, and on startup. No need to do it per-operation. This removes the 'need_reseed' parameter from generate_random_buffer(). This also requires that we start the secrets subsystem, as that is where the reseed value is stored, for systems without /dev/urandom. In order to aviod identical streams in forked children, the random state is re-initialised after the fork(), at the same point were we do that to the tdbs. Andrew Bartlett (This used to be commit b97d3cb2efd68310b1aea8a3ac40a64979c8cdae)
2007-10-10r1486: commit the start of the generic server infastructureStefan Metzmacher1-62/+76
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...
