* SECURITY.Ruslan Ermilov2001-09-042-40/+42
| | | | | | | | | | | | | | | | Fixed macros for temporarily relinquishing and restoring setuid/setgid privileges so that they never change the real user and group IDs of the calling process. The setre[ug]id() calls are still used in the REDUCE_PERM macro (with the r[ug]id arguments of -1) so that the call changes the saved user and group IDs of the process to that specified. Also, the panic() and perr() functions had insufficient privileges to delete the problematic file under /var/at. Notes: svn path=/head/; revision=82973
* The implementation of -flags was broken and did not match the (poorly)Ruslan Ermilov2001-09-043-31/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | documented behavior. Only a certain set of file flags were recognized, and "no" flags did not match files that have corresponding flags bits turned off. Fix and extend the -flags functionality as follows: : -flags [-|+]<flags>,<notflags> : The flags are specified using symbolic names (see chflags(1)). : Those with the "no" prefix (except "nodump") are said to be : <notflags>. Flags in <flags> are checked to be set, and flags in : <notflags> are checked to be not set. Note that this is different : from -perm, which only allows the user to specify mode bits that : are set. : : If flags are preceded by a dash (``-''), this primary evaluates : to true if at least all of the bits in <flags> and none of the bits : in <notflags> are set in the file's flags bits. If flags are pre- : ceded by a plus (``+''), this primary evaluates to true if any of : the bits in <flags> is set in the file's flags bits, or any of the : bits in <notflags> is not set in the file's flags bits. Otherwise, : this primary evaluates to true if the bits in <flags> exactly match : the file's flags bits, and none of the <flags> bits match those of : <notflags>.
