++ help
++ If you say Y here, /dev/kmem and /dev/mem won't be allowed to
++ be written to or read from to modify or leak the contents of the running
++ kernel. /dev/port will also not be allowed to be opened and support
++ for /dev/cpu/*/msr will be removed. If you have module
++ support disabled, enabling this will close up five ways that are
++ currently used to insert malicious code into the running kernel.
++
++ Even with all these features enabled, we still highly recommend that
++ you use the RBAC system, as it is still possible for an attacker to
++ 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

++ 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.
++ Enabling this feature will prevent the "cpupower" and "powertop" tools
++ from working.

++ unprivileged use of the PERF_EVENTS syscall interface will be permitted.
++
++ Though PERF_EVENTS can be used legitimately for performance monitoring
++ and low-level application profiling, it is forced on regardless of
++ configuration, has been at fault for several vulnerabilities, and
++ creates new opportunities for side channels and other information leaks.
++

++ If you say Y here, a random-sized gap will be enforced between allocated
++ thread stacks. Glibc's NPTL and other threading libraries that
++ pass MAP_STACK to the kernel for thread stack allocation are supported.
++ The implementation currently provides 8 bits of entropy for the gap.
++
++ Many distributions do not compile threaded remote services with the
++ -fstack-check argument to GCC, causing the variable-sized stack-based
++ allocator, alloca(), to not probe the stack on allocation. This
++ permits an unbounded alloca() to skip over any guard page and potentially
++ modify another thread's stack reliably. An enforced random gap
++ reduces the reliability of such an attack and increases the chance
++ that such a read/write to another thread's stack instead lands in
++ an unmapped area, causing a crash and triggering grsecurity's
++ anti-bruteforcing logic.

++ If you say Y here, the /proc/<pid>/maps and /proc/<pid>/stat files will

++ /proc/<pid> entries where the file descriptor was opened in a different
++ task than the one performing the read. Such attempts are logged.
++ This option also limits argv/env strings for suid/sgid binaries
++ to 512KB to prevent a complete exhaustion of the stack entropy provided
++ by ASLR. Finally, it places an 8MB stack resource limit on suid/sgid

++ 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
++ existing instances of the suid/sgid binary terminated and will
++ be unable to execute any suid/sgid binaries for 15 minutes.
++

++ 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"
++ select PAX_USERCOPY_SLABS
++ default y if GRKERNSEC_CONFIG_AUTO
++ 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.

++ 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
++ all processes owned by the user, then prevent them from creating
++ any new processes until the system is restarted
++ This deters repeated kernel exploitation/bruteforcing attempts
++ and is useful for later forensics.

++ sent to ports for which no associated listening process exists.
++ This feature supports both IPV4 and IPV6 and exempts the
++ loopback interface from blackholing. Enabling this feature
++ makes a host more resilient to DoS attacks and reduces network
++ visibility against scanners.
++
++ The blackhole feature as-implemented is equivalent to the FreeBSD
++ blackhole feature, as it prevents RST responses to all packets, not
++ just SYNs. Under most application behavior this causes no
++ problems, but applications (like haproxy) may not close certain
++ connections in a way that cleanly terminates them on the remote
++ end, leaving the remote host in LAST_ACK state. Because of this
++ side-effect and to prevent intentional LAST_ACK DoSes, this
++ feature also adds automatic mitigation against such attacks.
++ The mitigation drastically reduces the amount of time a socket
++ can spend in LAST_ACK state. If you're using haproxy and not

++ disabling this feature on the haproxy host.
++
++ If the sysctl option is enabled, two sysctl options with names

++ While "ip_blackhole" takes the standard zero/non-zero on/off
++ toggle, "lastack_retries" uses the same kinds of values as

++
++ As the weakness could be used to prevent an antivirus or IPS from

++ 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)
++ depends on !HIBERNATION
++ 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.
++
++ 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 commandline parameter
++ "pax_sanitize_slab=0".
++
++ 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.
++
++config PAX_MEMORY_STACKLEAK
++ 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.
++
++config PAX_MEMORY_STRUCTLEAK
++ bool "Forcibly initialize local variables copied to userland"
++ default y if (GRKERNSEC_CONFIG_AUTO && GRKERNSEC_CONFIG_PRIORITY_SECURITY)
++ help
++ By saying Y here the kernel will zero initialize some local
++ variables that are going to be copied to userland. This in
++ turn prevents unintended information leakage from the kernel
++ 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.
++
++ 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.
++
++config PAX_MEMORY_UDEREF
++ bool "Prevent invalid userland pointer dereference"
++ default y if GRKERNSEC_CONFIG_AUTO && (X86_32 || (X86_64 && GRKERNSEC_CONFIG_PRIORITY_SECURITY)) && (GRKERNSEC_CONFIG_VIRT_NONE || GRKERNSEC_CONFIG_VIRT_EPT)
++ depends on X86 && !UML_X86 && !XEN
++ select PAX_PER_CPU_PGD if X86_64
++ 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.
++
++config PAX_REFCOUNT
++ bool "Prevent various kernel object reference counter overflows"
++ default y if GRKERNSEC_CONFIG_AUTO
++ depends on GRKERNSEC && ((ARM && (CPU_32v6 || CPU_32v6K || CPU_32v7)) || SPARC64 || X86)
++ 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
++ this feature.
++
++config PAX_USERCOPY
++ bool "Harden heap object copies between kernel and userland"
++ default y if GRKERNSEC_CONFIG_AUTO
++ depends on ARM || IA64 || PPC || SPARC || X86
++ depends on GRKERNSEC && (SLAB || SLUB || SLOB)
++ 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.
++
++config PAX_USERCOPY_DEBUG
++ bool
++ depends on X86 && PAX_USERCOPY
++ default n
++
++config PAX_CONSTIFY_PLUGIN
++ bool "Automatically constify eligible structures"
++ default y if GRKERNSEC_CONFIG_AUTO
++ depends on !UML && PAX_KERNEXEC
++ help
++ By saying Y here the compiler will automatically constify a class
++ of types that contain only function pointers. This reduces the
++ kernel's attack surface and also produces a better memory layout.
++
++ 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
++ can be found in PaX itself (the no_const attribute) and for some
++ out-of-tree modules at http://www.grsecurity.net/~paxguy1/ .
++
++
++config PAX_SIZE_OVERFLOW
++ bool "Prevent various integer overflows in function size parameters"
++ default y if GRKERNSEC_CONFIG_AUTO
++ depends on X86
++ help
++ By saying Y here the kernel recomputes expressions of function
++ arguments marked by a size_overflow attribute with double integer
++ precision (DImode/TImode for 32/64 bit integer types).
++
++ The recomputed argument is checked against TYPE_MAX and an event
++ is logged on overflow and the triggering process is killed.
++
++ Homepage: http://www.grsecurity.net/~ephox/overflow_plugin/
++
++ 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.
++
++config PAX_LATENT_ENTROPY
++ bool "Generate some entropy during boot"
++ default y if GRKERNSEC_CONFIG_AUTO
++ help
++ By saying Y here the kernel will instrument early boot code to
++ extract some entropy from both original and artificially created
++ 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.
++
++ 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
++ slowdown of the boot process.
++
++ 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 entropy extracted this way is not cryptographically
++ secure!
