While exploring some of the source I found out that some permission checks are made too late. For example the sys_mount function in 2.6-test1: It gets 4 pages to put the type, the path, the dev name and the options. It then locks the kernel, check for magic numbers and other sanity checks, interprets the flags, does the mount point dentry lookup(which might spend some time sleeping) and after all that it checks for CAP_SYS_ADMIN. Is there any serious reason for this delay at the permission checks? _________________________________________________________________ Add photos to your messages with MSN 8.
