2009-11-03s3: Remove debug_ctx()Volker Lendecke2-7/+7
smbd just crashed on me: In a debug message I called a routine preparing a string that itself used debug_ctx. The outer routine also used it after the inner routine had returned. It was still referencing the talloc context that the outer debug_ctx() had given us, which the inner DEBUG had already freed.

2009-03-26Fix a scary "fill_share_mode_lock failed" messageVolker Lendecke1-1/+2
To me "fill_share_mode_lock failed" is a "can't happen" alert. There is however a perfectly valid case in get_file_infos() when the file is not open. Change the corresponding debug message to level 10 and explain more.

2009-02-19s3: Add extid to the dev/inode pairTim Prouty1-3/+3
This extends the file_id struct to add an additional generic uint64_t field: extid. For backwards compatibility with dev/inodes stored in xattr_tdbs and acl_tdbs, the ext id is ignored for these databases. This patch should cause no functional change on systems that don't use SMB_VFS_FILE_ID_CREATE to set the extid. Existing code that uses the smb_share_mode library will need to be updated to be compatibile with the new extid.

2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch2-52/+95
This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS, BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically: * I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to *_default as the default implementations of the VFS ops. * The blocking_lock_record (BLR) is now passed into the brl_lock_windows and brl_cancel_windows paths. The Onefs implementation uses it - future implementations may find it useful too. * Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a lock_struct and call either the Posix or Windows lock function. These happen to be the same for the default implementation. * Added helper functions: increment_current_lock_count() and decrement_current_lock_count(). * Minor spelling correction in brl_timeout_fn: brl -> blr. * Changed blocking_lock_cancel() to return the BLR that it has cancelled. This allows us to assert its the lock that we wanted to cancel. If this assert ever fires, this path will need to take in the BLR to cancel, rather than choosing on its own. * Adds a small helper function: find_blocking_lock_record_by_id(). Used by the OneFS implementation, but could be useful for others.

2009-02-09s3 oplocks: Make the level2 oplock contention API more granularTim Prouty1-11/+74
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.

2008-09-05Write times code update.Jeremy Allison1-5/+28
Ok, here's the fix for the write times breakage with the new tests in S4 smbtorture. The key is keeping in the share mode struct the "old_file_time" as the real write time, set by all the write and allocation calls, and the "changed_write_time" as the "sticky" write time - set by the SET_FILE_TIME calls. We can set them independently (although I kept the optimization of not setting the "old_file_time" is a "changed_write_time" was already set, as we'll never see it. This allows us to update the write time immediately on the SMBwrite truncate case, SET_END_OF_FILE and SET_ALLOCATION_SIZE calls, whilst still have the 2 second delay on the "normal" SMBwrite, SMBwriteX calls. I think in a subsequent patch I'd like to change the name of these from "old_file_time" to "write_time" and "changed_write_time" to "sticky_write_time" to make this clearer. I think I also fixed a bug in Metze's original code in that once a write timestamp had been set from a "normal" SMBwriteX call the fsp->update_write_time_triggered variable was set and then never reset - thus meaning the write timestamp would never get updated again on subsequent SMBwriteX's. The new code checks the update_write_time_event event instead, and doesn't update is there's an event already scheduled. Metze especially, please check this over for your understanding. Jeremy.

2008-04-21Don't modify the fsp in fd_close_posix() anymore.Michael Adam1-4/+0
Now that it is inside the vfs layer, this function should not alter the fsp (i.e. set fsp->fh->fd = -1) anymore. That belongs above the vfs layer. Michael (This used to be commit df264bf3e00d7d77afcf55e54d2669b9ffa9af4a)
2008-04-21Move the posix pending close functionality down into the VFS layer.Michael Adam1-3/+3
This hides the pending close fds from the outside. Call order of SMB_VFS_CLOSE is reversed. Originally, it was: fd_close -> fd_close_posix -> SMB_VFS_CLOSE -> close And now it is: fd_close -> SMB_VFS_CLOSE -> fd_close_posix -> close This is in preparation of removing the fd parameter from the SMB_VFS_CLOSE function. But it is also the right place for the pending close calls anyways. Michael (This used to be commit 3cf56b124a2886c6260455bba4bf77d08e9a4f77)
