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.
2011-05-31s3-globals Remove smbd_event_context() (use server_event_context())Andrew Bartlett1-2/+2
This has been a wrapper around server_event_context() for some time now, and removing this from dummmysmbd.c assists with library dependencies. Andrew Bartlett

2010-12-15Change interface of schedule_smb2_aio_read() to allocate the return DATA_BLOB.Jeremy Allison1-3/+11
Change smb2_read code to allocate return DATA_BLOB just before the read. Preparing for SMB2 sendfile change which will not need to allocate return buffer. Jeremy

Jeremy.
2010-07-18s3: Work better without the aio sighandlerVolker Lendecke1-7/+22
Refuse async I/O if we can't set up the signal handler
2010-06-10Fix the build in the non WITH_AIO case (sorry).Jeremy Allison1-0/+20
2010-06-10Implement AIO in SMB2. Doesn't allow cancel calls yet (to be added).Jeremy Allison1-0/+281
Jeremy.
2010-06-07Make aio_ex owned by a talloc context, not neccessarily on the null context.Jeremy Allison1-8/+12

2010-06-04Change smbd_aio_complete_mid() -> smbd_aio_complete_aio_ex(). SimplifiesJeremy Allison1-32/+4
the code and eliminates find_aio_ex(). Jeremy.
2010-06-02Move to using a DATA_BLOB inside of struct aio_extra, not a char *.Jeremy Allison1-16/+16
Will make using AIO in SMB2 easier. Jeremy.
2010-06-01Don't use sigev_value.sival_int to just store the mid, use ↵Jeremy Allison1-38/+26
sigev_value.sival_ptr to store the private data structure. This allows easier use from SMB2. Ensure aio is initialized before the aio_pending_size check else aio will never be used. Jeremy.
2010-05-07This patch looks bigger than it is. It does 2 things. 1). Renames smbpid -> ↵Jeremy Allison1-2/+2
smblctx in our locking code. 2). Widens smblctx to 64-bits internally. Preparing to use the SMB2 handle as the locking context. Jeremy.
2010-04-12Move to using 64-bit mid values in our internal open file database.Jeremy Allison1-15/+23
This will allow us to share logic much easier between SMB1 and SMB2 servers. Jeremy
2010-04-05Fix issue with aio where r/w lock wasn't kept across aio read operations.Jeremy Allison1-23/+56
Change schedule_aio_read_and_X/schedule_aio_write_and_X to return NTSTATUS. Move the grant and release of the lock into the aio code. Jeremy
2010-04-01Move initialize_async_io_handler() inside of smbd/aio.c.Jeremy Allison1-34/+42
Call from actual aio read or write. No reason to call this globally on startup. Jeremy.
2009-10-13Remove use of "int ret" when we already have errcode.Jeremy Allison1-13/+8
Jeremy.
2009-10-13Catch one more erroneous use of errno.Jeremy Allison1-1/+1

Jeremy.
2009-07-20s3: Change fsp->fsp_name to be an smb_filename struct!Tim Prouty1-14/+14
2009-06-08Set SIGRTMIN to NSIGTimur I. Bakeyev1-3/+0
In the includes we define SIGRTMIN to 32 if it's not defined already. This value could be fairly low and it's better to use NSIG(number of defined signals) as the lower mark for the available signals. We have similar defenition in the source3/smbd/aio.c, which can be safely removed, as it comes from includes.h then. With regards, Timur Bakeyev. Signed-off-by: Stefan Metzmacher <metze@samba.org>
2009-05-18Move down the become_root()/unbecome_root() calls into the VFS modulesVolker Lendecke1-6/+0
The aio_fork module does not need this, as it does not communicate via signals but with pipes. Watching a strace log with those become_root() calls in aio.c is absolutely awful, and it does affect performance.
2009-03-23s3:smbd: use new simplified snb_signing code in the serverStefan Metzmacher1-8/+5
We keep the seqnum/mid mapping in the smb_request structure. This also moves one global variable into the smbd_server_connection struct. metze
2009-03-06s3:signing: the seqnum should only be decremented by 1 for ntcancel requestsStefan Metzmacher1-4/+4
[MS-SMB] 3.3.5.1 Receiving Any Message says that the seqnum is incremented by only for ntcancel requests for any other request it's by incremented by 2, even if it doesn't expect a response. metze
2009-02-09s3 oplocks: Make the level2 oplock contention API more granularTim Prouty1-1/+3
This replaces release_level2_oplocks_on_change with contend_level2_oplock_begin/end in order to contend level2 oplocks throughout an operation rather than just at the begining. This is necessary for some kernel oplock implementations, and also lays the groundwork for better correctness in Samba's standard level2 oplock handling. The next step for non-kernel oplocks is to add additional state to the share mode lock struct that prevents any new opens from granting oplocks while a contending operation is in progress. All operations that contend level 2 oplocks are now correctly spanned except for aio and synchronous writes. The two write paths both have non-trivial error paths that need extra care to get right. RAW-OPLOCK and the rest of 'make test' are still passing with this change.
