2009-02-13OneFS implementation of BRL VFS ops:Zack Kirsch3-2/+476
* Much of the beginning should look familiar, as I re-used the OneFS oplock callback record concept. This was necessary to keep our own state around - it really only consists of a lock state, per asynchronous lock that is currently unsatisfied. The onefs_cbrl_callback_records map to BLRs by the id. * There are 4 states an async lock can be in. NONE means there is no async currently out for the lock, as opposed to ASYNC. DONE means we've locked *every* lock (keep in mind a request can ask for multiple locks at a time.) ERROR is an error. * onefs_cbrl_async_success: The lock_num is incremented, and the state changed, so that when process_blocking_lock_queue is run, we will try the *next* lock, rather than the same one again. * onefs_brl_lock_windows() has some complicated logic: * We do a no-op if we're passed a BLR and the matching state is ASYNC -- this means Samba is trying to get the same lock twice, and we just need to wait longer, so we return an error. * PENDING lock calls happen when the lock is being queued on the BLQ -- we do async in this case. * We also do async in the case that we're passed a BLR, but the lock is not pending. This is an async lock being probed by process_blocking_lock_queue. * We do a sync lock for any normal first request of a lock. * Failure is returned, but it doesn't go to the client unless the lock has actually timed out.
2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch2-0/+114
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: OneFS bulk directory enumeration supportSteven Danneman4-19/+690
OneFS provides the bulk directory enumeration syscall readdirplus(). This syscall has the same semantics as the NFSv3 READDIRPLUS command, returning a batch of directory entries with prefetched stat information via one syscall. This commit wraps the readdirplus() call in the existing POSIX readdir/seekdir VFS interface. By default a batch of 128 directory entries are optimistically read from the kernel into a global cache, and fed to iterative calls of VFS_OP_READDIR. The global buffers could be avoided in the future by hanging connection specific buffers off the conn struct. Added new parameter "onefs:use readdirplus" which toggles usage of this code on or off.
2009-02-09s3: Added SMB_VFS_INIT_SEARCH_OP to initialize data at the beginning of SMB ↵Steven Danneman2-0/+23
search requests. By default this VFS call is a NOOP, but the onefs vfs module takes advantage of it to initialize direntry search caches at the beginning of each TRANS2_FIND_FIRST, TRANS2_FIND_NEXT, SMBffirst, SMBsearch, and SMBunique
2009-02-09Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIRSteven Danneman8-12/+20
* this allows VFS implementations that prefetch stat information on readdir to return it through one VFS call * backwards compatibility is maintained by passing in NULL * if the system readdir doesn't return stat info, the stat struct is set to invalid
2009-02-09s3 OneFS: Change ACLs to do a stat-only open before get/set_security_descriptorTim Prouty1-22/+4
This ensures that getting/stting a security descriptor does not contend an oplock. The correct access checks will be still be done in the kernel on the get/set rather than the open.
2009-02-09s3 OneFS: Add kernel oplocks implementationTim Prouty3-81/+134
A few functions in oplocks_onefs.c need to be accessed from the onefs vfs module. It would be ideal if oplocks were implemented at the vfs layer, but since they aren't yet, a new header is added to source3/include to make these functions available to the onefs vfs module. oplocks_onefs.o doesn't need to be linked into the onefs vfs module explicitly, since it is already linked into smbd by default.
2009-02-09s3 vfs: Add a destructor to the fsp extension data APITim Prouty4-4/+5

2009-02-09s3 OneFS: Fake Timestampstodd stecher3-14/+242
This checkin enables setting arbitrary timestamps on files matching the pattern stored in smb.conf. This was a customer request for a specific workflow. Changes include: 1) configuration state machine to avoid tons of string comparisons on each and every stat. 2) Code to adjust post-stat() times to match time now, or sloptime + time now.

2009-01-23Extend NTIMES to allow setting create_timetodd stecher6-20/+24
1) Add in smb_file_time struct to clarify code and make room for createtime. 2) Get and set create time from SMB messages. 3) Fixup existing VFS modules + examples Some OS'es allow for the setting of the birthtime through kernel interfaces. This value is generically used for Windows createtime, but is not settable in the code today.
2009-01-23s3: OneFS unmappable sids support.Dan Sledz3-67/+183
Updates the onefs vfs module to add configurable behavior to deal with sids that are unknown to us. The best examples are aces that come from robocopy/xcopy. Adds the following share level options (which are specific to the vfs_onefs module): onefs: ignore unmappable sids (Default = false) If this option is set to true, sids which could not be resolved to a uid/gid are ignored. If an unmappable sid is encountered as the owner or group, the owner/group is converted to BUILTIN\Administrators. onefs: unmappable sids ignore list (Default = empty) Only the sids in the list are ignored. onefs: ignore sacls (Default = false) SACLs are ignored onefs: unmappable sids deny everyone (Default = false) If an unmappable sid is found in a deny ACE, the ACE's identity is changed to Everyone.
