2013-02-04vfs_acl_common: Do not fetch the underlying NT ACL unless we need itAndrew Bartlett1-44/+80
This avoids asking for the posix ACL on disk twice, and avoids running a good deal of mapping code if it is not needed. Andrew Bartlett Signed-off-by: Andrew Bartlett <abartlet@samba.org> Reviewed-by: Christian Ambach <ambi@samba.org>

2013-02-04vfs: Implement an improved vfs_acl_common that uses the hash of the system ACLAndrew Bartlett1-51/+250
Where supported by the system ACL backend, this avoids hashing the result of the ACL mapping, instead hashing the original ACL, linearlised. For maximum robustness, the hash of the NT and system ACL are stored, along with the time and a description of the system ACL. This variety of extra metadata may assist some future implementation in determining which hash to validate.

2012-12-04s3:smbd:vfs_acl: fix a PANIC when setting an ACL fails with ACCESS_DENIEDMichael Adam1-0/+1
Omission to free the talloc frame causes a panic (at least in developer mode) in the next main event loop due to "Frame not freed in order." (Freed frame ../source3/smbd/process.c:3617, expected ../source3/modules/vfs_acl_common.c:534.)

2012-10-11smbd: Add mem_ctx to {f,}get_nt_acl VFS callAndrew Bartlett1-23/+45
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.

2011-02-22s3-auth Rename auth_serversupplied_info varaiables: server_info -> session_infoAndrew Bartlett1-2/+2
These variables, of type struct auth_serversupplied_info were poorly named when added into 2001, and in good consistant practice, this has extended all over the codebase in the years since. The structure is also not ideal for it's current purpose. Originally intended to convey the results of the authentication modules, it really describes all the essential attributes of a session. This rename will reduce the volume of a future patch to replaced these with a struct auth_session_info, with auth_serversupplied_info confined to the lower levels of the auth subsystem, and then eliminated. (The new structure will be the output of create_local_token(), and the change in struct definition will ensure that this is always run, populating local groups and privileges).
