* Fix more POSIX path lstat calls. Fix bug where close can returnJeremy Allison2009-02-251-5/+17
| | | | | | | | | failure if we have a pending modtime and the containing directory of the file has been renamed (there is no POSIX "update time by fd" call). This can't happen on Windows as the rename will fail if there are open files beneath it. Will add a torture test for this. Jeremy.

* Fix bug in processing of open modes in POSIX open.Jeremy Allison2009-02-251-0/+2
| | | | | | | Was missing case of "If file exists open. If file doesn't exist error." Damn damn damn. CIFSFS client will have to have fallback cases for this error for a long time. Jeremy.

* s3: If sendfile returns 0 bytes read, fall back to the normal read pathTim Prouty2009-02-211-0/+24
| | | | | | This allows sendfile implementations that are atomic to avoid having to send zeros or kill the client connection on a short read (usually the file was truncated).

| | | | | | | * This allows a problem in the underlying CN backend to be bubbled up to the general CN layer so a catch-all reply can be returned * We now also return a catch-all response immediately if the server-side event queue becomes too big
* s3: Modifications to generic notify structures to allow implementation of ↵Steven Danneman2009-02-201-0/+2
| | | | | | | | | | | | | | OneFS notify. The OneFS kernel based change notify system takes an fd of the directory to watch in it's initialization syscall. Since we already have this directory open, this commit plumbs that fd down to the VFS layer via the notify_entry struct. We also need to know if the watch is taken out on a snapshot directory. The full file_id struct is also passed down to make this determination. The file_id marshalling wrappers are hand written here, but should eventually be auto-generated by moving the struct file_id into the idl.

* s3: Add extid to the dev/inode pairTim Prouty2009-02-194-17/+20
| | | | | | | | | | | 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.
* s3: Modify SMB_VFS_FILE_ID_CREATE to take a stat structTim Prouty2009-02-191-0/+18
| | | | | Since file_id_create_dev is incompatible with the concept of file_ids, it is now static and in the one file that needs it.

* s3: Fix bug opening streams with truncating dispositionTim Prouty2009-02-181-1/+1
| | | | | | | Do not attempt to delete streams on a truncating open, if the name we're opening is itself a stream. Port 176e8857203944bc332844b700749120ce90c891 to standard open path
* S3: Stop creating SMBD cores when failing to create a pipe.todd stecher2009-02-181-0/+4
| | | | | | This was uncovered when the MAX FD limit was hit, causing an instant core and invoking error reporting. This fix causes SMBD to exit, but without building a core.
* S3: Allow SMBD processes to survive in low memory condidtionstodd stecher2009-02-181-0/+7
| | | | | | This commit adds a configure argument which allows for setting MADV_PROTECT in the madvise() API. With this enabled the kernel won't kill SMBD when it's running low on memory.

* Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch2009-02-133-53/+75
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | 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
* Pass stat buffer down through all levels of VFS_READDIR wrappersSteven Danneman2009-02-094-96/+103

* Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIRSteven Danneman2009-02-091-2/+2
| | | | | | | | * 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
* s3 OneFS: Add kernel oplocks implementationTim Prouty2009-02-092-0/+805
| | | | | | | | | 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.
* s3 oplocks: Remove oplocks before handling delete on close semanticsTim Prouty2009-02-091-4/+5
| | | | | | Unlinking a file while still holding an oplock can cause problems with kernel oplocks. This simply releases the oplock before actually unlinking the file.
* s3 oplocks: Add capabilites flags field to the kernel_oplocks structTim Prouty2009-02-092-2/+32
| | | | | | | | | | | | | | | | Here is a short description for each of the new capability flags: KOPLOCKS_LEVEL2_SUPPORTED: Level 2 oplocks are supported natively in the kernel. KOPLOCKS_DEFERRED_OPEN_NOTIFICATION: The kernel notifies deferred openers when they can retry the open. KOPLOCKS_TIMEOUT_NOTIFICATION: The kernel notifies smbds when an oplock break times out. KOPLOCKS_OPLOCK_BROKEN_NOTIFICATION: The kernel notifies smbds when an oplock is broken.
* s3 oplocks: Make the level2 oplock contention API more granularTim Prouty2009-02-097-27/+62
| | | | | | | | | | | | | | | | | | 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.
* s3 oplocks: Differentiate between releasing an oplock vs. downgrading to ↵Tim Prouty2009-02-093-4/+4
| | | | | | | Level 2 for kernel oplocks Pass in an extra argument when releasing an oplock so kernel oplock implementations can support downgrading from Level 1 to Level 2.

* Add two new parameters to control how we verify kerberos tickets. Removes ↵Dan Sledz2009-02-012-3/+3
| | | | | | | | | | | | | | | | | | | | | | | lp_use_kerberos_keytab parameter. The first is "kerberos method" and replaces the "use kerberos keytab" with an enum. Valid options are: secrets only - use only the secrets for ticket verification (default) system keytab - use only the system keytab for ticket verification dedicated keytab - use a dedicated keytab for ticket verification. secrets and keytab - use the secrets.tdb first, then the system keytab For existing installs: "use kerberos keytab = yes" corresponds to secrets and keytab "use kerberos keytab = no" corresponds to secrets only The major difference between "system keytab" and "dedicated keytab" is that the latter method relies on kerberos to find the correct keytab entry instead of filtering based on expected principals. The second parameter is "dedicated keytab file", which is the keytab to use when in "dedicated keytab" mode. This keytab is only used in ads_verify_ticket.
