-+
-+ Objects with extension .so are considered shared libraries, and
-+ will be compiled as position independent objects.
-+ Kbuild provides support for shared libraries, but the usage
-+ shall be restricted.
-+ In the following example the libkconfig.so shared library is used
-+ to link the executable conf.
-+
-+ Example:
-+ #scripts/kconfig/Makefile
-+ hostprogs-y := conf
-+ conf-objs := conf.o libkconfig.so
-+ libkconfig-objs := expr.o type.o
-+
-+ Shared libraries always require a corresponding -objs line, and
-+ in the example above the shared library libkconfig is composed by
-+ the two objects expr.o and type.o.
-+ expr.o and type.o will be built as position independent code and
-+ linked as a shared library libkconfig.so. C++ is not supported for
-+ shared libraries.

-+ The implementation currently provides 8 bits of entropy for the gap.
-+
-+ Many distributions do not compile threaded remote services with the

-+ 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

-+ system can hide that entry even from root.
-+
-+ This option also prevents leaking of kernel addresses through

-+ 2) You have also enabled GRKERNSEC_DMESG
-+ 3) You are using the RBAC system and hiding other files such as your

-+ 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

-+ help
-+ Many if not most exploit techniques rely on the knowledge of
-+ certain addresses in the attacked program. The following options
-+ will allow the kernel to apply a certain amount of randomization
-+ to specific parts of the program thereby forcing an attacker to
-+ guess them in most cases. Any failed guess will most likely crash
-+ the attacked program which allows the kernel to detect such attempts
-+ and react on them. PaX itself provides no reaction mechanisms,
-+ instead it is strongly encouraged that you make use of grsecurity's
-+ (http://www.grsecurity.net/) built-in crash detection features or
-+ develop one yourself.
-+
-+ By saying Y here you can choose to randomize the following areas:
-+ - top of the task's kernel stack
-+ - top of the task's userland stack
-+ - base address for mmap() requests that do not specify one
-+ (this includes all libraries)
-+ - base address of the main executable
-+
-+ It is strongly recommended to say Y here as address space layout
-+ randomization has negligible impact on performance yet it provides
-+ a very effective protection.

-+ 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
-+ may cause unexpected stack overflows, therefore you should very

-+ 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 .

-+ as passwords, cryptographic secrets, etc stay in memory for too long.
-+
-+ This is especially useful for programs whose runtime is short, long

-+ they ensure timely freeing of memory that may hold sensitive

-+
-+ A nice side effect of the sanitization of slab objects is the

-+
-+ The tradeoff is that some virtualization solutions may experience

-+ * This plugin 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.
-+ *
-+ * Usage:
-+ * $ make
-+ * $ make run
