This patch implements GetNamedSecurityInfoW on top of the more fundamental GetSecurityInfo function, permitting the return of more accurate ownership information for files. PlayReady uses this information to determine if its files have the appropriate permissions, without the correct permissions it will attempt to recopy the individualization file (and fail). Additionally, this patch adds tests for retrieving the ACL information set on files.
This version fixes some problems in the tests on older Windows versions, sorry I didn't catch that earlier. It now also fixes a mistake I made between testing try 2 and pushing it out :/
- hfile = CreateFileW( name, access, FILE_SHARE_READ|FILE_SHARE_WRITE|FILE_SHARE_DELETE,
NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, 0 );
Only works on files right now, huh? You might then want to check to make sure the caller says it's a file by comparing the 'type' against SE_FILE_OBJECT, and return ERROR_CALL_NOT_IMPLEMENTED if they didn't. After all, part of the point of that parameter is to tell you which function you need to call to open the object in the first place :). (Same for patch 2.)
