++User convenience variables, et cetera, have associated types. Normally these

++
++Types with null @code{TYPE_OBJFILE} can be either permanent types
++(@pxref{Builtin Types}) or reclaimable types which will be deallocated at the
++first idle @value{GDBN} moment if the last object referencing them is removed.
++Permanent types are allocated by the function @code{alloc_type} (and its
++derivations like @code{init_type}) specifying objfile as @code{NULL}. The
++reclaimable types are created the same way but moreover they need to have
++@code{type_init_group} called to start their tracking as being possibly
++deallocatable.
++
++@findex free_all_types
++When @value{GDBN} gets idle it always calls the @code{free_all_types} function
++which deallocates any unused types. All types currently not owned by an
++objfile must be marked as used on each @code{free_all_types} call as they would
++get deallocated as unused otherwise.
++
++@code{free_all_types} automatically checks for any cross-type references such
++as through @code{TYPE_TARGET_TYPE}, @code{TYPE_POINTER_TYPE} etc.@: and
++prevents early deallocation for any such existing references. Reclaimable
++types may reference any other reclaimable types or even permanent types. But
++permanent types must not reference reclaimable types (nor an objfile associated
++type).

++ not be allowed to mprotect it with PROT_WRITE later.

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

-+ 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

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

-+ clock support is enabled if this option is enabled, to ensure

-+ binaries.
-+
-+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, as well as against suid/sgid binaries
-+ will be deterred. When a child of a forking daemon is killed by PaX
-+ or crashes due to an illegal instruction or other suspicious signal,
-+ 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.
-+ In the suid/sgid case, the attempt is logged, the user has all their
-+ processes terminated, and they are prevented from executing any further
-+ processes for 15 minutes.
-+ It is recommended that you also enable signal logging in the auditing
-+ section so that logs are generated when a process triggers a suspicious
-+ signal.
-+ If the sysctl option is enabled, a sysctl option with name
-+ "deter_bruteforce" is created.

-+ 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.
-+
-+config GRKERNSEC_HIDESYM
-+ bool "Hide kernel symbols"
-+ help
-+ If you say Y here, getting information on loaded modules, and
-+ displaying all kernel symbols through a syscall will be restricted
-+ 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.
-+
-+ This option also prevents leaking of kernel addresses through
-+ several /proc entries.
-+
-+ 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 have also enabled GRKERNSEC_DMESG
-+ 3) 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
