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.
2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-3/+5
This changelist allows for the addition of custom performance monitoring modules through smb.conf. Entrypoints in the main message processing code have been added to capture the command, subop, ioctl, identity and message size statistics.

2009-01-08s3:smbd: move all globals and static variables in globals.[ch]Stefan Metzmacher1-16/+10
The goal is to move all this variables into a big context structure. metze

2008-11-04Rewrite aio.c to keep the whole smb_request structure, not just the inbufVolker Lendecke1-75/+41
2008-11-04Add construct_reply_common_req wrapperVolker Lendecke1-1/+1
The goal is to remove the remaining direct calls to construct_reply_common.

Sooner or later this would bite us.

2008-09-15Fix aio on FreeBSD.Timur1-1/+16
2008-08-26become root for AIO operationsAndrew Tridgell1-1/+7
We need to become root for AIO read and write to allow the AIO thread to send a completion signal to the parent process when the IO completes (This used to be commit c548e5c69f9d8bc85a654f4d29d64c735a5e780b)
2008-02-24Allow "max mux" async i/o requestsVolker Lendecke1-5/+9
In the negprot reply, we allowed the client to issued "max mux" concurrent requests. The OS might allow less, for example AFAIK AIX has a configurable limit of concurrent AIO requests. We will fall back to sync operation for the requests that are too many when aio_read/aio_write return an error. Jeremy, please check! (This used to be commit 8f86f7f25c4eb71bbdfcc6bf2d12eaaae9a8d9ec)
2008-02-24Export aio_request_done()Volker Lendecke1-3/+9
This is for external modules implementing the Posix AIO API that not necessarily depend on the signal mechanism to indicate completion. (This used to be commit 9a069d306bb6f8a2cd51b8ba87b433884942d13f)

Necessary to survive RAW-SEEK with AIO enabled. Jeremy, please check! (This used to be commit e2ca12c2345c0e3916dd09d097b2ba1ce2989fa8)

2008-01-30Re-enable async I/O for non-TSM systemsVolker Lendecke1-2/+4
The logic was wrong: A "SMB_VFS_AIO_FORCE()==False" disabled async I/O, whereas a "SMB_VFS_AIO_FORCE()==True" should enforce it regardless of other settings. Alexander, please check! (This used to be commit 46882ad9927c95caadeb7fb03c1d7491bbe1fb22)

with Volker. Mostly making sure we have data on the incoming packet type, not stored in the smb header. Jeremy. (This used to be commit c4e5a505043965eec77b5bb9bc60957e8f3b97c8)

2007-10-10r22411: Fix the build:Michael Adam1-3/+5
Prototype of create_aio_ex_read, set_message and definition of UNIXERROR have changed in r22389 and r22391? to require an additional "inbuf" argument. Some places in smbd/aio.c had not been adapted. This patch fixes the build. Michael (This used to be commit 9de1af6dc835fa12a75bae00935cd605f61217a3)

to all callers of smb_setlen (via set_message() calls). This will allow the server to reflect back the correct encryption context. Jeremy. (This used to be commit 2d80a96120a5fe2fe726f00746d36d85044c4bdb)

2007-10-10r21279: Get rid of 'aio write behind', this is broken.Volker Lendecke1-155/+1
It should probably better be integrated with our write cache. Volker (This used to be commit 58bfd168b046a97a895aaa3384fd7af8d077a1d5)
2007-10-10r21278: The main goal of this was to get rid of the NetInBuffer / ↵Volker Lendecke1-41/+13
set_InBuffer. But it turns out that this patch actually speeds up the async writes considerably. I tested writing 100.000 times 65535 bytes with the allowed 10 ops in parallel. Without this patch it took about 32 seconds on my dual-core 1.6GHz laptop. With this patch it dropped to about 26 seconds. I can only explain it by better cache locality, NewInBuffer allocates more than 128k, so we jump around in memory more. Jeremy, please check!

2007-10-10r21277: Fix an off by one error in the signal handler for aio: We can ↵Volker Lendecke1-1/+1
actually receive AIO_PENDING_SIZE signals, not one less. Jeremy I'm not merging this to 3_0_25, I want you to look at it first! Volker (This used to be commit 8fd0ec58360a349826508fc361a943650fdd6694)

2007-10-10r20237: Replace exit_server with exit_server_cleanly where appropriate. AllJames Peach1-3/+3
send_smb failures should be clean exits. All times when we exit as a matter of policy should also be clean exits. (This used to be commit d6382092e72120a3c89ffe81975e8898d454bf06)
