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. ++ ++config PAX_REFCOUNT ++ bool "Prevent various kernel object reference counter overflows" ++ default y if GRKERNSEC_CONFIG_AUTO ++ depends on GRKERNSEC && ((ARM && (CPU_V6 || CPU_V6K || CPU_V7)) || MIPS || PPC || 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_CONSTIFY_PLUGIN ++ bool "Automatically constify eligible structures" ++ default y ++ 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_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_SIZE_OVERFLOW ++ bool "Prevent various integer overflows in function size parameters" ++ default y if GRKERNSEC_CONFIG_AUTO ++ depends on GCC_PLUGINS ++ 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: https://github.com/ephox-gcc-plugins ++ ++ Note that the implementation requires a gcc with plugin support, ++ i.e., gcc 4.5 or newer.

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.
