* s3-aio: Panic if we try to close a fsp with outstanding aio requestsVolker Lendecke2012-07-193-18/+15
| | | | | | | | | | | The core smbd must have taken care of this. If we don't do this properly, we have a race of the close(2) against a pwrite(2). We might end up writing to the wrong file.

* config: The AIO engine is indepent of HAVE_AIO nowVolker Lendecke2012-07-183-30/+31
| | | | | | | | | Compile the basic aio engine always, it works via libasys/pthreadpool_sync in a sync fashion even if no pthreads are around. Everything else (linux aio, posix aio, aio fork) is now compiled as modules based on specific system capabilities Signed-off-by: Jeremy Allison <jra@samba.org>

* s3:smbstatus add --fast optionChristian Ambach2012-07-181-4/+11
| | | | | | this option skips all checks if the process for the record is still there using it gives a huge performance benefit on busy systems and clusters while it might display stale data if a smbd crashed
* s3:smbstatus don't check if process exists twiceChristian Ambach2012-07-181-4/+0

* source3/netapi: fix only caller which doesn't set up a talloc_stackframe()Rusty Russell2012-07-181-0/+4
| | | | | | | | libnetapi_free() needs a stackframe too; looked like Andrew and Günther missed this in a37de9a95974c138d264d9cb0c7829bb426bb2d6. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* source3/passdb/py_passdb.c: wrap all calls in talloc_stackframe()Rusty Russell2012-07-181-519/+489
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dbwrap needs it. Some calls were already wrapped, but they checked the talloc_stackframe() return unnecessarily: it can never be NULL. This is the coccinelle patch I used: // Add in a stackframe to every function: be sure to free it on (every) return @rule0@ identifier func; @@ func(...) { +TALLOC_CTX *frame = talloc_stackframe(); <... +talloc_free(frame); return ...; ...> } // Get rid of tframe allocation/frees, replace usage with frame. @rule1@ identifier func; identifier oldframe; @@ func(...) { ... -TALLOC_CTX *oldframe; ... -if ((oldframe = talloc_stackframe()) == NULL) { - ... -} <... -talloc_free(oldframe); ...> } // Get rid of tframe (variant 2) @rule2@ identifier func; identifier oldframe; @@ func(...) { ... -TALLOC_CTX *oldframe; ... -oldframe = talloc_stackframe(); -if (oldframe == NULL) { - ... -} <... -talloc_free(oldframe); ...> } // Change tframe to frame @rule3@ identifier func; @@ func(...) { <... -tframe +frame ...> } Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* source3/passdb/py_passdb.c: don't steal from talloc_stackframe().Rusty Russell2012-07-181-15/+2
| | | | | | | | | | If you want a stack-style allocation, use talloc_stackframe(). If you don't, don't use it. In particular, talloc_stackframe() here is actually inside a pool, and stealing from pools is a bad idea. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* loadparm: make the source3/ lp_ functions take an explicit TALLOC_CTX *.Rusty Russell2012-07-1885-621/+660
| | | | | | | | | | They use talloc_tos() internally: hoist that up to the callers, some of whom don't want to us talloc_tos(). A simple patch, but hits a lot of files. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
