2013-09-05smbd: Fix breaking level2 on allocateVolker Lendecke1-6/+7
This needs doing even if we don't have strct allocate set. The client should not know that we lied. Fixes smb2.oplock.batch12. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

2013-01-16s3-vfs: add copy_chunk vfs hooksDavid Disseldorp1-2/+24
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: Remove type parameter from sys_acl_blob_get_{fd,file}Andrew Bartlett1-2/+1
This interface actually needs to match the get_nt_acl interface in that the system ACL implmenetation may not be posix ACLs, and the blob is not meant to be enforced to be of a particular system ACL structure. Andrew Bartlett
2012-10-11smbd: Add mem_ctx to {f,}get_nt_acl VFS callAndrew Bartlett1-2/+4
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/+6
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
2012-09-13Sigh :-(. Removing optimization prematurely is the root of all evil :-(.Jeremy Allison1-0/+13
Sorry for the mistake, but the LastDir singleton cache in vfs_ChDir() actually plays an important role. When we're processing a stream of SMB1/SMB2/SMB3 requests we don't want to add a chdir()/getcwd() system call pair on every request if they're all on the same connection and dealing with the same base path. I did some testing with a program that times 1,000,000 chdir() requests vs. 1,000,000 strcmp requests and it's a penalty of 10x doing the system calls. Just because it's old code, doesn't mean it's bad :-(. Autobuild-User(master): Jeremy Allison <jra@samba.org> Autobuild-Date(master): Thu Sep 13 21:31:42 CEST 2012 on sn-devel-104

2012-09-12smbd: Add extra VFS hooks to get the posix ACL as a blobAndrew Bartlett1-0/+21
This will allow us to hash this, rather than the NT ACL it maps to. This will in turn allow us to know if the NT ACL is valid even if we have to change the mapping code.

2012-08-15s3-smbd: Remove sys_acl_*() VFS wrapper functionsAndrew Bartlett1-129/+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
