These differences\n might include privilege required for a given library\n provided interface to function properly, as occurs\n from time to time in graphics libraries. There are\n also cases where it is important to limit use of\n libraries based on the provider of the library and\n the security aware application may make choices\n based on that criteria.\n\n These issues are addressed by providing an additional\n Smack label that may optionally be assigned to an object,\n the SMACK64MMAP attribute. An mmap operation is allowed\n if there is no such attribute.\n\n If there is a SMACK64MMAP attribute the mmap is permitted\n only if a subject with that label has all of the access\n permitted a subject with the current task label.\n\n Security aware applications may from time to time\n wish to reduce their \"privilege\" to avoid accidental use\n of privilege. One case where this arises is the\n environment in which multiple sources provide libraries\n to perform the same functions. An application may know\n that it should eschew services made available from a\n particular vendor, or of a particular version.\n\n In support of this a secondary list of Smack rules has\n been added that is local to the task. This list is\n consulted only in the case where the global list has\n approved access. It can only further restrict access.\n Unlike the global last, if no entry is found on the\n local list access is granted. An application can add\n entries to its own list by writing to /smack/load-self.\n\n The changes appear large as they involve refactoring\n the list handling to accomodate there being more\n than one rule list.\n\nSigned-off-by: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\n" }, { "commit": "5c6d1125f8dbd1bfef39e38fbc2837003be78a59", "tree": "368d34e800bc5478442679323270d776b79501e8", "parents": [ "fe27d4b012273640e033be80f143bdc54daa8e16" ], "author": { "name": "Jarkko Sakkinen", "email": "ext-jarkko.2.sakkinen@nokia.com", "time": "Tue Dec 07 13:34:01 2010 +0200" }, "committer": { "name": "Casey Schaufler", "email": "casey@schaufler-ca.com", "time": "Tue Dec 07 14:04:02 2010 -0800" }, "message": "Smack: Transmute labels on specified directories\n\nIn a situation where Smack access rules allow processes\nwith multiple labels to write to a directory it is easy\nto get into a situation where the directory gets cluttered\nwith files that the owner can\u0027t deal with because while\nthey could be written to the directory a process at the\nlabel of the directory can\u0027t write them.
