-+ project. While you are there, download chpax and run it on

-+ /dev/port will also not be allowed to be opened. If you have module

-+ modify the running kernel through privileged I/O granted by ioperm/iopl.
-+ If you are not using XFree86, you may be able to stop this additional
-+ case by enabling the 'Disable privileged I/O' option. Though nothing
-+ legitimately writes to /dev/kmem, XFree86 does need to write to /dev/mem,
-+ but only to video memory, which is the only writing we allow in this
-+ case. If /dev/kmem or /dev/mem are mmaped without PROT_WRITE, they will
-+ not be allowed to mprotect it with PROT_WRITE later.

-+ video cards and will still work with this option enabled. The purpose

-+ remedied by having RTC support in the kernel, so real-time
-+ clock support is enabled if this option is enabled, to ensure
-+ that hwclock operates correctly. XFree86 still will not

-+config GRKERNSEC_BRUTE
-+ bool "Deter exploit bruteforcing"
-+ help
-+ If you say Y here, attempts to bruteforce exploits against forking
-+ daemons such as apache or sshd will be deterred. When a child of a
-+ forking daemon is killed by PaX or crashes due to an illegal
-+ instruction, the parent process will be delayed 30 seconds upon every
-+ subsequent fork until the administrator is able to assess the
-+ situation and restart the daemon. It is recommended that you also
-+ enable signal logging in the auditing section so that logs are
-+ generated when a process performs an illegal instruction.
-+
-+config GRKERNSEC_MODHARDEN
-+ bool "Harden module auto-loading"
-+ depends on MODULES
-+ help
-+ If you say Y here, module auto-loading in response to use of some
-+ feature implemented by an unloaded module will be restricted to
-+ root users. Enabling this option helps defend against attacks
-+ by unprivileged users who abuse the auto-loading behavior to
-+ cause a vulnerable module to load that is then exploited.
-+
-+ If this option prevents a legitimate use of auto-loading for a
-+ non-root user, the administrator can execute modprobe manually
-+ with the exact name of the module mentioned in the alert log.
-+ Alternatively, the administrator can add the module to the list
-+ of modules loaded at boot by modifying init scripts.
-+
-+ Modification of init scripts will most likely be needed on
-+ Ubuntu servers with encrypted home directory support enabled,
-+ as the first non-root user logging in will cause the ecb(aes),
-+ ecb(aes)-all, cbc(aes), and cbc(aes)-all modules to be loaded.

-+ help
-+ If you say Y here, getting information on loaded modules, and

-+ to users with CAP_SYS_MODULE. For software compatibility reasons,
-+ /proc/kallsyms will be restricted to the root user. The RBAC
-+ system can hide that entry even from root. Note that this option
-+ is only effective provided the following conditions are met:
-+ 1) The kernel using grsecurity is not precompiled by some distribution
-+ 2) You are using the RBAC system and hiding other files such as your
-+ kernel image and System.map. Alternatively, enabling this option
-+ causes the permissions on /boot, /lib/modules, and the kernel
-+ source directory to change at compile time to prevent
-+ reading by non-root users.
-+ If the above conditions are met, this option will aid in providing a
-+ useful protection against local kernel exploitation of overflows
