2007-10-10r12804: This patch reworks the Samba4 sockets layer to use a socket_addressAndrew Bartlett1-6/+24
structure that is more generic than just 'IP/port'. It now passes make test, and has been reviewed and updated by metze. (Thankyou *very* much). This passes 'make test' as well as kerberos use (not currently in the testsuite). The original purpose of this patch was to have Samba able to pass a socket address stucture from the BSD layer into the kerberos routines and back again. It also removes nbt_peer_addr, which was being used for a similar purpose. It is a large change, but worthwhile I feel.

2007-10-10r8520: fixed a pile of warnings from the build farm gcc -Wall output onAndrew Tridgell1-3/+4
S390. This is an attempt to avoid the panic we're seeing in the automatic builds. The main fixes are: - assumptions that sizeof(size_t) == sizeof(int), mostly in printf formats - use of NULL format statements to perform dn searches. - assumption that sizeof() returns an int (This used to be commit a58ea6b3854973b694d2b1e22323ed7eb00e3a3f)
2007-10-10r8284: - fixed some uninitialised variables in the irpc codeAndrew Tridgell1-4/+8
- added code to send multiple irpc calls in parallel, to all servers that have registered the given name, with output going in io.results[i]. This allows you to make rpc calls to multiple servers at once, which is needed for clients like smbstatus (This used to be commit 061e20e509d95ffe16d7dd6fba7db39fc7a165ed)

Steven Edwards <steven_ed4153@yahoo.com>. I've moved the Win32-specific tests to win32.m4 so it does not make any of the POSIX configure stuff more complicated. (This used to be commit bf85fdd01552f75b745fdf3159a7a87cd6521ed2)
2007-10-10r7320: added support for a private pointer in irpc registered handlersAndrew Tridgell1-2/+5

fixes a IO_TIMEOUT problem in the messaging benchmarks (This used to be commit c8b220b65de00418d19347cf298cc80d86e8accb)
2007-10-10r7296: avoid two stat() calls per message. This increases the raw messageAndrew Tridgell1-8/+7
rate from 20k/sec to 55k/sec. The irpc rate goes from 16k/sec to 34k/sec. I should have run strace -T on this a long time ago. (This used to be commit b9281668bb0c971af14df37ec3e979b9d5ef276e)
2007-10-10r7295: added an irpc benchmark. It gets about 16k messages/sec on my laptop,Andrew Tridgell1-7/+14
compared to about 20k messages/sec for the raw messaging layer. I think that is quite acceptable given the extra functionality. (This used to be commit a05d38d1d91f1f54d3e3794a596b468992594852)
2007-10-10r7294: implemented the irpc messaging system. This is the core of theAndrew Tridgell1-2/+281
management system I proposed on samba-technical a couple of days ago. Essentially it is a very lightweight way for any code in Samba to make IDL based rpc calls to anywhere else in the code, without the client or server having to go to the trouble of setting up a full rpc service. It can be used with any of our existing IDL, but I expect it will mostly be used for a new set of Samba specific management calls. The LOCAL-IRPC torture test demonstrates how it can be used by calling the echo_AddOne() call over this transport. (This used to be commit 3d589a09954eb8b318f567e1150b0c27412fb942)
2007-10-10r7228: use socket_pending() instead of the direct ioctl in the messaging codeAndrew Tridgell1-5/+6
(This used to be commit ca3c4e961713ffd8952fca328e27196ba2ccc0c9)
2007-10-10r7211: - use ioctl(FIONREAD) to remove the artificial limit on messaging sizeAndrew Tridgell1-42/+51
- avoid a memcpy (This used to be commit 753839c358f45c02927b137092828f3a79158083)
2007-10-10r7206: changed the messaging library to use sendto instead of a connectedAndrew Tridgell1-119/+94
send on the unix domain datagram socket. This gains us about 50% in speed, and also means that we don't run the risk of running out of file descriptors due to heavy messaging traffic. We now use a single file descriptor no matter how many messages are pending to any number of servers. (This used to be commit 2369170fc1b4ff9a48284779fa6d3a6254177ec1)
2007-10-10r6578: brown paper bag time with the new messaging code ....Andrew Tridgell1-1/+1

sockets. This gains us about 40% in messaging speed. (This used to be commit f244a64ed537447e44229172427b5b6a5c64800c)
2007-10-10r5304: removed lib/socket/socket.h from includes.hAndrew Tridgell1-0/+1
(This used to be commit b902ea546d2d1327b23f40ddaeeaa8e7e3662454)
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)
2007-10-10r5197: moved events code to lib/events/ (suggestion from metze)Andrew Tridgell1-1/+1
(This used to be commit 7f54c8a339f36aa43c9340be70ab7f0067593ef2)
2007-10-10r5195: most events don't need the time of the event, so save a ↵Andrew Tridgell1-3/+3
gettimeofday() call and just use timeval_current() when its actually needed (This used to be commit 236403cc4dc2924ed6a898acae0bb44cc1688dcc)
2007-10-10r5185: make all the events data structures private to events.c. This willAndrew Tridgell1-50/+26
make it possible to add optimisations to the events code such as keeping the next timed event in a sorted list, and using epoll for file descriptor events. I also removed the loop events code, as it wasn't being used anywhere, and changed timed events to always be one-shot (as adding a new timed event in the event handler is so easy to do if needed) (This used to be commit d7b4b6de51342a65bf46fce772d313f92f8d73d3)
2007-10-10r5102: This is a major simplification of the logic for controlling top levelAndrew Tridgell1-11/+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)
2007-10-10r5037: got rid of all of the TALLOC_DEPRECATED stuff. My apologies for theAndrew Tridgell1-4/+4
large commit. I thought this was worthwhile to get done for consistency. (This used to be commit ec32b22ed5ec224f6324f5e069d15e92e38e15c0)
2007-10-10r4944: every event_add_*() caller was having to call talloc_steal() to takeAndrew Tridgell1-10/+5
control of the event, so instead build that into the function. If you pass NULL as mem_ctx then it leaves it as a child of the events structure. (This used to be commit 7f981b9ed96f39027cbfd500f41e0c2be64cbb50)
2007-10-10r4943: Smplified the events handling code a lot. The first source ofAndrew Tridgell1-17/+4
complexity was that events didn't automatically cleanup themselves. This was because the events code was written before we had talloc destructors, so you needed to call event_remove_XX() to clean the event out of the event lists from every piece of code that used events. I have now added automatic event destructors, which in turn allowed me to simplify a lot of the calling code. The 2nd source of complexity was caused by the ref_count, which was needed to cope with event handlers destroying events while handling them, which meant the linked lists became invalid, so the ref_count ws used to mark events for later destruction. The new system is much simpler. I now have a ev->destruction_count, which is incremented in all event destructors. The event dispatch code checks for changes to this and handles it. (This used to be commit a3c7417cfeab429ffb22d5546b205818f531a7b4)
2007-10-10r4727: add a reference to the event contextStefan Metzmacher1-1/+1
to that the destructor don't double free the registered events when the event context is first in the talloc_free() hierarchie fixes a bug with process_model_thread and the talloc_steal(conn, ev) metze (This used to be commit 05c3d1c4a6a6350cc8b5fb2ee8201ae6feed3d3d)
2007-10-10r4063: - change char * -> uint8_t in struct request_bufferStefan Metzmacher1-1/+1
- change smbcli_read/write to take void * for the buffers to match read(2)/write(2) all this fixes a lot of gcc-4 warnings metze (This used to be commit b94f92bc6637f748d6f7049f4f9a30b0b8d18a7a)
2007-10-10r3507: - added deferred replies on sharing violation in pvfs open. TheAndrew Tridgell1-10/+41
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)
2007-10-10r3481: split out client.h and events.hAndrew Tridgell1-0/+1
(This used to be commit c6f486574470a311e0d336c026103f131451e21e)
2007-10-10r3463: separated out some more headers (asn_1.h, messages.h, dlinklist.h and ↵Andrew Tridgell1-0/+2
ioctl.h) (This used to be commit b97e395c814762024336c1cf4d7c25be8da5813a)
2007-10-10r3447: more include/system/XXX.h include filesAndrew Tridgell1-0/+1
(This used to be commit 264ce9181089922547e8f6f67116f2d7277a5105)
2007-10-10r3360: improved the deletion of tmp files. smbd now puts all tmp files in ↵Andrew Tridgell1-2/+2
var/locks/smbd.tmp/ and deletes that dir on startup. (This used to be commit 7e942e7f1bd2c293a0e6648df43a96f8b8a2a295)
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. (This used to be commit 406d356e698da01c84e8aa5b7894752b4403f63c)
2007-10-10r3304: changed the API to lib/socket/ a little.Andrew Tridgell1-19/+17
The main change is to make socket_recv() take a pre-allocated buffer, rather than allocating one itself. This allows non-blocking users of this API to avoid a memcpy(). As a result our messaging code is now about 10% faster, and the ncacn_ip_tcp and ncalrpc code is also faster. The second change was to remove the unused mem_ctx argument from socket_send(). Having it there implied that memory could be allocated, which meant the caller had to worry about freeing that memory (if for example it is sending in a tight loop using the same memory context). Removing that unused argument keeps life simpler for users. (This used to be commit a16e4756cd68ca8aab4ffc59d4d9db0b6e44dbd1)
2007-10-10r3271: use "struct messaging_context *" instead of "void *" in messaging APIAndrew Tridgell1-22/+19
(This used to be commit cc93813e4a09c538ad485dc2b3cb4c9be34f3d18)
2007-10-10r3183: moved the unlink of the messaging unixdom socket to the messaging ↵Andrew Tridgell1-0/+1
destructor (This used to be commit ab222b236a091d31b1f5f2cba150a11585ab5836)
2007-10-10r3034: - fixed a bug in message dispatch, when the dispatch function called ↵Andrew Tridgell1-2/+3
messaging_deregister() - added a pvfs_lock_close_pending() hook to remove pending locks on file close - fixed the private ptr argument to messaging_deregister() in pvfs_wait - fixed a bug in continuing lock requests after a lock that is blocking a pending lock is removed - removed bogus brl_unlock() call in lock continue - corrected error code for LOCKING_ANDX_CHANGE_LOCKTYPE - expanded the lock cancel test suite to test lock cancel by unlock and by close - added a testsuite for LOCKING_ANDX_CHANGE_LOCKTYPE (This used to be commit 5ef80f034d4aa4dd6810532c63ad041bfc019cb8)
2007-10-10r3029: implemented byte range lock timeouts.Andrew Tridgell1-2/+3
This adds a pvfs_wait_message() routine which uses the new messaging system, event timers and talloc destructors to give a nice generic async event handling system with a easy to use interface. The extensions to pvfs_lock.c are based on calls to pvfs_wait_message() routines. We now pass all of our smbtorture locking tests, although while writing this code I have thought of some additonal tests that should be added, particularly for lock cancel operations. I'll work on that soon. This commit also extends the smbtorture lock tests to test the rather weird 0xEEFFFFFF locking semantics that I have discovered in win2003. Win2003 treats the 0xEEFFFFFF boundary as special, and will give different error codes on either side of it. Locks on both sides are allowed, the only difference is which error code is given when a lock is denied. Anyone like to hazard a guess as to why? It has me stumped. (This used to be commit 4395c0557ab175d6a8dd99df03c266325949ffa5)
