2012-11-20s3:smbd/aio do not mark file modified during readsChristian Ambach1-2/+0
this causes each file that is potentially just opened for reading to be marked as modified and lots of file change notifications will be send Signed-off-by: Christian Ambach <ambi@samba.org> Reviewed-by: Volker Lendecke <vl@samba.org> Autobuild-User(master): Christian Ambach <ambi@samba.org> Autobuild-Date(master): Tue Nov 20 21:02:34 CET 2012 on sn-devel-104
2012-07-19s3-aio: Panic if we try to close a fsp with outstanding aio requestsVolker Lendecke1-16/+0
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.

2012-07-18s3-smb1: Postpone close_file until all aio is handledVolker Lendecke1-0/+5
Thanks to Jeremy for this simple idea Signed-off-by: Jeremy Allison <jra@samba.org>
2012-07-18s3-aio: Make the strict sync after write asyncVolker Lendecke1-18/+103
This restores cb405947caa9f4bdb962483860a9093a364ecbf2, which was lost during the refactoring of aio.c and vfs_aio_pthread.c. Signed-off-by: Jeremy Allison <jra@samba.org>

2012-07-12Add an optimization to pthread aio writes to also do fsync if requested.Jeremy Allison1-0/+9
Should help by ensuring complete writes done in sub-thread, not in the main thread.

2012-06-26s3: Restore async i/o with the "native" AIO interfaceVolker Lendecke1-3/+0
eff3609 moved the async signal handler initialization to later in the process to enable aio_fork and aio_pthread on platforms without realtime signals. This commit broke the use of the native aio interface. aio_pending_size is initialized to 0, so aio.c will not allow async i/0 at all if modules do not set that variable correctly. Initialize to 100 right from the start.

2012-06-15s3:smbd: change aio.c to use fsp_fnum_dbg() for logging fsp->fnum.Michael Adam1-2/+2
Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-06-06build: Rationalise AIO support in configure, ensure on by defaultAndrew Bartlett1-1/+1
With this change, the define to check for AIO is HAVE_AIO, consistant with other subsystems. It is now also on by default in the autoconf build, as it has been for waf. Andrew Bartlett
2012-04-12We never cancel SMB1 aio, only SMB2 aio - and in this case we always return ↵Jeremy Allison1-12/+7
a value. So pass_cancel is no longer needed.
2012-04-12Remove cancel_aio_by_fsp(). It can never work and could lead to memory ↵Jeremy Allison1-30/+9
corruption as outstanding IO's complete. Also we never have any aio's on a call to close_normal_file() with close_type ERROR_CLOSE.
2012-04-12Move the counting of outstanding_aio_calls into the lifecycle of the ↵Jeremy Allison1-6/+2
aio_extra struct. This way we can't end up with a mismatch between outstanding events and the counter. We may still have problems with canceling and not correctly freeing the aio struct, but at least the counter won't get out of sync anymore.
2012-04-09s3: Move the aio signal init to the vfs moduleVolker Lendecke1-21/+7
On platforms that don't have an RT signal space, signal initialization fails. aio_fork and aio_pthread don't need the signal, so this would block them from running as well.
2012-04-06build: Remove SMB_OFF_T, replace with off_tAndrew Bartlett1-6/+6
Now that we always require a 64 bit off_t, we no longer need SMB_OFF_T. Andrew Bartlett Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Fri Apr 6 01:47:43 CEST 2012 on sn-devel-104

2011-06-09s3-talloc Change TALLOC_ZERO_P() to talloc_zero()Andrew Bartlett1-1/+1
Using the standard macro makes it easier to move code into common, as TALLOC_ZERO_P isn't standard talloc.
