Issue #2817 has been updated by liweitianux. Status changed from New to Resolved
This issue was answered and can be closed. ---------------------------------------- Bug #2817: Permission checking for utimes(2) and friends are not properly honoured http://bugs.dragonflybsd.org/issues/2817#change-13705 * Author: stateless * Status: Resolved * Priority: Normal * Assignee: dillon * Category: Kernel * Target version: ---------------------------------------- Changing the access and modification times of a file to anything other than the current time can only be done by the owner of the file or the super-user as per POSIX. At present it is possible to do so just by having write access to the file. A simple example follows: touch foo; chown root:user foo; chmod 664 foo; touch -t 200805101024 foo The last operation should normally fail. I noticed this as part of my work on adding support for utimensat(). I believe the fix can be consolidated outside of the implementation of the utimes/utimensat system calls. -- You have received this notification because you have either subscribed to it, or are involved in it.
