2013-01-18Move copychunk locking to be local to the read/write calls.Jeremy Allison1-0/+42
Eliminates the need to hold locks across the entire lifetime of the call. Next commit will remove these. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>
2013-01-16s3-vfs: add copy_chunk vfs hooksDavid Disseldorp1-0/+111
copy_chunk copies n bytes from a source file at a specific offset to a destination file at a given offset. This interface will be used in handling smb2 FSCTL_SRV_COPYCHUNK ioctl requests. Use a pread/pwrite loop in vfs_default, so that requests referring to the same src and dest file are possible. Provide send and receive hooks for copy chunk VFS interface, allowing asynchronous behaviour. Check whether the request source offset + length exceeds the current size. Return STATUS_INVALID_VIEW_SIZE under such a condition, matching Windows server behaviour. Reviewed by: Jeremy Allison <jra@samba.org>

2012-10-11vfs: Improve formatting of vfs_defaultAndrew Bartlett1-23/+23
This avoids this bad style being copied into new modules. Andrew Bartlett
2012-10-11vfs: Use posix_sys_acl_blob_get_file in vfs_default for posix ACLsAndrew Bartlett1-0/+2
2012-10-11smbd: Add mem_ctx to {f,}get_nt_acl VFS callAndrew Bartlett1-2/+6
This makes it clear which context the returned SD is allocated on, as a number of callers do not want it on talloc_tos(). As the ACL transformation allocates and then no longer needs a great deal of memory, a talloc_stackframe() call is used to contain the memory that is not returned further up the stack. Andrew Bartlett
2012-10-11smbd: Add mem_ctx to sys_acl_init() and all callersAndrew Bartlett1-4/+9
This changes from allocation on NULL to allocation on the supplied memory context. Currently that supplied context is talloc_tos() at the the final consumer of the ACL. Andrew Bartlett
2012-09-08s3:vfs_default: add basic support for durable handle request and reconnectMichael Adam1-3/+6
We only grant durable handles for CIFS/SMB2 only access, that means "kernel oplocks", "kernel share modes" and "posix locking" need to be set to "no". For now we also don't grant durable handles if delete on close is active on the handle. Pair-Programmed-With: Stefan Metzmacher <metze@samba.org> Pair-Programmed-With: Volker Lendecke <vl@samba.org>
2012-09-08s3:vfs: add durable VFS operationsMichael Adam1-1/+34
This allows a VFS module to implement durable handles in different ways. Pair-Programmed-With: Stefan Metzmacher <metze@samba.org>
2012-08-15s3-smbd: Remove sys_acl_*() VFS wrapper functionsAndrew Bartlett1-102/+0
We no longer do struct smb_acl_t manipuations via the VFS layer, which is now reduced to handling the get/set functions. The only backend that implemented these functions (aside from audit) was the vfs_default module calling the sys_acl code. The various ACL implementation modules either worked on the fully initilaised smb_acl_t object or on NT ACLs. This not only makes the operation of the posix ACL code more efficient (as allocation and free is not put via the VFS), it makes it easier to test and removes the fantasy that a module could safely redefine this structure or the behaviour here. The smb_acls.idl now defines the structure, and it is now allocated with talloc. These operations were originally added to the VFS in commit 3bb219161a270f12c27c3bc7e1220829c6e9f284. Andrew Bartlett

2012-07-18loadparm: make the source3/ lp_ functions take an explicit TALLOC_CTX *.Rusty Russell1-1/+1
They use talloc_tos() internally: hoist that up to the callers, some of whom don't want to us talloc_tos(). A simple patch, but hits a lot of files. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2012-06-15s3:vfs_default: use fsp_fnum_dbg() for fsp->fnum logging.Michael Adam1-6/+10
Note: it is actually wrong to access the fsp->fnum at all here, since the fnum is part of the smb layer that should not be used in the vfs layer. But this is subject be separated more cleanly in later commits. This change only unifies the logging of fsp->fnum. Signed-off-by: Stefan Metzmacher <metze@samba.org>

2012-04-09s3: Move the aio signal init to the vfs moduleVolker Lendecke1-0/+8
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.
2012-04-06Bug found by Herb. blkcnt_t st_ex_blksize is defined as a signed value. When ↵Jeremy Allison1-0/+13
it is on a 32-bit system and defined as a long, then inside vfswrap_get_alloc_size() we cast to a uint64_t. This sign-extends when converting to unsigned, so if the high bit of st_ex_blksize is set we return insane values to clients.

2012-03-26s3: Pass filters explicitly through vfs notify watchVolker Lendecke1-3/+4
This removes a dependency on "struct notify_entry" and makes the nature of the API more explicit. We depend upon the VFS module to mask out elements from e->filter and e->subdir_filter that it took over to handle.
