-+ Modifying the LDT (Local Descriptor Table) may be needed to run a
-+ 16-bit or segmented code such as Dosemu or Wine. This is done via
-+ a system call which is not needed to run portable applications,
-+ and which can sometimes be abused to exploit some weaknesses of
-+ the architecture, opening new vulnerabilities.
-+
-+ For this reason this option allows one to enable or disable the
-+ feature at runtime. It is recommended to say 'N' here to leave
-+ the system protected, and to enable it at runtime only if needed
-+ by setting the sys.kernel.modify_ldt sysctl.

-+ modify another thread's stack reliably. An enforced random gap
-+ reduces the reliability of such an attack and increases the chance

-+ This option also limits argv/env strings for suid/sgid binaries

-+
-+ It is recommended that you also enable signal logging in the auditing

-+ 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),

-+config GRKERNSEC_HIDESYM

-+ default y if GRKERNSEC_CONFIG_AUTO
-+ select PAX_USERCOPY_SLABS
-+ 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
-+ 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
-+ and arbitrary read/write vulnerabilities.
-+
-+ It is highly recommended that you enable GRKERNSEC_PERF_HARDEN
-+ in addition to this feature.

-+ If you say Y here, the layouts of a number of sensitive kernel
-+ structures (task, fs, cred, etc) and all structures composed entirely
-+ of function pointers (aka "ops" structs) will be randomized at compile-time.
-+ This can introduce the requirement of an additional infoleak
-+ vulnerability for exploits targeting these structure types.
-+
-+ Enabling this feature will introduce some performance impact, slightly
-+ increase memory usage, and prevent the use of forensic tools like
-+ Volatility against the system (unless the kernel source tree isn't
-+ cleaned after kernel installation).
-+
-+ The seed used for compilation is located at tools/gcc/randomize_layout_seed.h.
-+ It remains after a make clean to allow for external modules to be compiled
-+ with the existing seed and will be removed by a make mrproper or
-+ make distclean.
-+

-+ help
-+ If you say Y here, when a PaX alert is triggered due to suspicious
-+ activity in the kernel (from KERNEXEC/UDEREF/USERCOPY)
-+ or an OOPS occurs due to bad memory accesses, instead of just
-+ terminating the offending process (and potentially allowing
-+ a subsequent exploit from the same user), we will take one of two
-+ actions:
-+ If the user was root, we will panic the system
-+ If the user was non-root, we will log the attempt, terminate

-+ will be created. Setting its value to 1 will prevent any new
-+ USB devices from being recognized by the OS. Any attempted USB
-+ device insertion will be logged. This option is intended to be
-+ used against custom USB devices designed to exploit vulnerabilities
-+ in various USB device drivers.
-+
-+ For greatest effectiveness, this sysctl should be set after any
-+ relevant init scripts. This option is safe to enable in distros
-+ as each user can choose whether or not to toggle the sysctl.

-+ If you say Y here, a variant of GRKERNSEC_DENYUSB will be enabled
-+ that doesn't involve a sysctl entry. This option should only be
-+ enabled if you're sure you want to deny all new USB connections
-+ at runtime and don't want to modify init scripts. This should not
-+ be enabled by distros. It forces the core USB code to be built
-+ into the kernel image so that all devices connected at boot time
-+ can be recognized and new USB device connections can be prevented
-+ prior to init running.

-+ are mutable until the "grsec_lock" entry is set to a non-zero value.
-+ All features enabled in the kernel configuration are disabled at boot
-+ if you do not say Y to the "Turn on features by default" option.
-+ All options should be set at startup, and the grsec_lock entry should

-+ for features that affect processes running as root. Therefore,
-+ it is critical when using this option that the grsec_lock entry be
-+ enabled after boot. Only distros with prebuilt kernel packages
-+ with this option enabled that can ensure grsec_lock is enabled
-+ after boot should use this option.
-+ *Failure to set grsec_lock after boot makes all grsec features

-+ By saying Y here the kernel will randomize every task's kernel
-+ stack on every system call. This will not only force an attacker
-+ to guess it but also prevent him from making use of possible
-+ leaked information about it.
-+
-+ Since the kernel stack is a rather scarce resource, randomization

-+ select PAX_RANDUSTACK
-+ help
-+ By saying Y here the kernel will randomize every task's userland
-+ stack and use a randomized base address for mmap() requests that
-+ do not specify one themselves.
-+
-+ The stack randomization is done in two steps where the second
-+ one may apply a big amount of shift to the top of the stack and
-+ cause problems for programs that want to use lots of memory (more
-+ than 2.5 GB if SEGMEXEC is not active, or 1.25 GB when it is).
-+
-+ As a result of mmap randomization all dynamically loaded libraries
-+ will appear at random addresses and therefore be harder to exploit
-+ by a technique where an attacker attempts to execute library code
-+ for his purposes (e.g. spawn a shell from an exploited program that
-+ is running at an elevated privilege level).
-+
-+ Furthermore, if a program is relinked as a dynamic ELF file, its
-+ base address will be randomized as well, completing the full
-+ randomization of the address space layout. Attacking such programs
-+ becomes a guess game. You can find an example of doing this at
-+ http://pax.grsecurity.net/et_dyn.tar.gz and practical samples at
-+ http://www.grsecurity.net/grsec-gcc-specs.tar.gz .

-+config PAX_MEMORY_SANITIZE
-+ bool "Sanitize all freed memory"
-+ default y if (GRKERNSEC_CONFIG_AUTO && GRKERNSEC_CONFIG_PRIORITY_SECURITY)
-+ help
-+ By saying Y here the kernel will erase memory pages and slab objects
-+ as soon as they are freed. This in turn reduces the lifetime of data
-+ stored in them, making it less likely that sensitive information such
-+ as passwords, cryptographic secrets, etc stay in memory for too long.
-+
-+ This is especially useful for programs whose runtime is short, long
-+ lived processes and the kernel itself benefit from this as long as
-+ they ensure timely freeing of memory that may hold sensitive
-+ information.
-+
-+ A nice side effect of the sanitization of slab objects is the
-+ reduction of possible info leaks caused by padding bytes within the
-+ leaky structures. Use-after-free bugs for structures containing
-+ pointers can also be detected as dereferencing the sanitized pointer
-+ will generate an access violation.
-+
-+ The tradeoff is performance impact, on a single CPU system kernel
-+ compilation sees a 3% slowdown, other systems and workloads may vary
-+ and you are advised to test this feature on your expected workload
-+ before deploying it.
-+
-+ The slab sanitization feature excludes a few slab caches per default
-+ for performance reasons. To extend the feature to cover those as
-+ well, pass "pax_sanitize_slab=full" as kernel command line parameter.
-+
-+ To reduce the performance penalty by sanitizing pages only, albeit
-+ limiting the effectiveness of this feature at the same time, slab
-+ sanitization can be disabled with the kernel command line parameter
-+ "pax_sanitize_slab=off".
-+
-+ Note that this feature does not protect data stored in live pages,
-+ e.g., process memory swapped to disk may stay there for a long time.
-+

-+ bool "Sanitize kernel stack"
-+ default y if (GRKERNSEC_CONFIG_AUTO && GRKERNSEC_CONFIG_PRIORITY_SECURITY)
-+ depends on X86
-+ help
-+ By saying Y here the kernel will erase the kernel stack before it
-+ returns from a system call. This in turn reduces the information
-+ that a kernel stack leak bug can reveal.
-+
-+ Note that such a bug can still leak information that was put on
-+ the stack by the current system call (the one eventually triggering
-+ the bug) but traces of earlier system calls on the kernel stack
-+ cannot leak anymore.
-+
-+ The tradeoff is performance impact: on a single CPU system kernel
-+ compilation sees a 1% slowdown, other systems and workloads may vary
-+ and you are advised to test this feature on your expected workload
-+ before deploying it.
-+
-+ Note that the full feature requires a gcc with plugin support,
-+ i.e., gcc 4.5 or newer. You may need to install the supporting
-+ headers explicitly in addition to the normal gcc package. Using
-+ older gcc versions means that functions with large enough stack
-+ frames may leave uninitialized memory behind that may be exposed
-+ to a later syscall leaking the stack.

-+ stack should later code forget to explicitly set all parts of
-+ the copied variable.
-+
-+ The tradeoff is less performance impact than PAX_MEMORY_STACKLEAK
-+ at a much smaller coverage.

-+ help
-+ By saying Y here the kernel will be prevented from dereferencing
-+ userland pointers in contexts where the kernel expects only kernel
-+ pointers. This is both a useful runtime debugging feature and a
-+ security measure that prevents exploiting a class of kernel bugs.
-+
-+ The tradeoff is that some virtualization solutions may experience
-+ a huge slowdown and therefore you should not enable this feature
-+ for kernels meant to run in such environments. Whether a given VM
-+ solution is affected or not is best determined by simply trying it
-+ out, the performance impact will be obvious right on boot as this
-+ mechanism engages from very early on. A good rule of thumb is that
-+ VMs running on CPUs without hardware virtualization support (i.e.,
-+ the majority of IA-32 CPUs) will likely experience the slowdown.
-+
-+ On X86_64 the kernel will make use of PCID support when available
-+ (Intel's Westmere, Sandy Bridge, etc) for better security (default)
-+ or performance impact. Pass pax_weakuderef on the kernel command
-+ line to choose the latter.

-+ help
-+ By saying Y here the kernel will detect and prevent overflowing
-+ various (but not all) kinds of object reference counters. Such
-+ overflows can normally occur due to bugs only and are often, if
-+ not always, exploitable.
-+
-+ The tradeoff is that data structures protected by an overflowed
-+ refcount will never be freed and therefore will leak memory. Note
-+ that this leak also happens even without this protection but in
-+ that case the overflow can eventually trigger the freeing of the
-+ data structure while it is still being used elsewhere, resulting
-+ in the exploitable situation that this feature prevents.
-+
-+ Since this has a negligible performance impact, you should enable

-+
-+ Note that the implementation requires a gcc with plugin support,
-+ i.e., gcc 4.5 or newer. You may need to install the supporting
-+ headers explicitly in addition to the normal gcc package.
-+
-+ Note that if some code really has to modify constified variables
-+ then the source code will have to be patched to allow it. Examples

-+ select PAX_USERCOPY_SLABS
-+ help
-+ By saying Y here the kernel will enforce the size of heap objects
-+ when they are copied in either direction between the kernel and
-+ userland, even if only a part of the heap object is copied.
-+
-+ Specifically, this checking prevents information leaking from the
-+ kernel heap during kernel to userland copies (if the kernel heap
-+ object is otherwise fully initialized) and prevents kernel heap
-+ overflows during userland to kernel copies.
-+
-+ Note that the current implementation provides the strictest bounds
-+ checks for the SLUB allocator.
-+
-+ Enabling this option also enables per-slab cache protection against
-+ data in a given cache being copied into/out of via userland
-+ accessors. Though the whitelist of regions will be reduced over
-+ time, it notably protects important data structures like task structs.
-+
-+ If frame pointers are enabled on x86, this option will also restrict
-+ copies into and out of the kernel stack to local variables within a
-+ single frame.
-+
-+ Since this has a negligible performance impact, you should enable
-+ this feature.

-+ program state. This will help especially embedded systems where
-+ there is little 'natural' source of entropy normally. The cost
-+ is some slowdown of the boot process and fork and irq processing.
-+
-+ When pax_extra_latent_entropy is passed on the kernel command line,
-+ entropy will be extracted from up to the first 4GB of RAM while the
-+ runtime memory allocator is being initialized. This costs even more

-+
-+ Note that the implementation requires a gcc with plugin support,
