-+ be written to via mmap or otherwise to modify the running kernel.
-+ /dev/port will also not be allowed to be opened. If you have module

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

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

-+ remedied by having RTC support in the kernel, so real-time
-+ clock support is enabled if this option is enabled, to ensure

-+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 will be deterred. When a child of a
-+ forking daemon is killed by PaX or crashes due to an illegal
-+ instruction, 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. It is recommended that you also

-+ depends on MODULES
-+ 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.

-+ /proc/kallsyms will be restricted to the root user. The RBAC
-+ system can hide that entry even from root. 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 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.

-+ 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

-+ 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

-+ Due to implementation details the kernel must reserve a fixed

-+ in MB that will be reserved. Due to the same implementation
-+ details this size will always be rounded up to the next 2/4 MB

-+ 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 Nergal's
-+ segvguard (ftp://ftp.pl.openwall.com/misc/segvguard/) or 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.
-+

-+ 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
-+ may cause unexpected stack overflows, therefore you should very
-+ carefully test your system. Note that once enabled in the kernel
-+ configuration, this feature cannot be disabled on a per file basis.
-+
-+config PAX_RANDUSTACK
-+ bool "Randomize user stack base"
-+ depends on PAX_ASLR
-+ help
-+ By saying Y here the kernel will randomize every task's userland

-+ 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).
-+ For this reason the second step can be controlled by 'chpax' or
-+ 'paxctl' on a per file basis.
-+
-+config PAX_RANDMMAP
-+ bool "Randomize mmap() base"
-+ depends on PAX_ASLR
-+ help
-+ By saying Y here the kernel will use a randomized base address for
-+ mmap() requests that do not specify one themselves. As a result
-+ 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 .

-+ bool "Sanitize all freed memory"

-+ 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 operate on whole memory pages and ensure timely freeing of pages

-+ 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

-+ 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.

-+
-+ 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.

++ If you say Y here, many of the features of grsecurity will be

++ on your machine. Since this security level enables PaX, you should
++ view <http://pax.grsecurity.net> and read about the PaX
++ project. While you are there, download chpax and run it on
++ binaries that cause problems with PaX. Also remember that
++ since the /proc restrictions are enabled, you must run your
++ identd as gid 1001. This security level enables the following
++ features in addition to those listed in the low and medium
++ security levels:
++
++ - Additional /proc restrictions
++ - Chmod restrictions in chroot
++ - No signals, ptrace, or viewing of processes outside of chroot
++ - Capability restrictions in chroot
++ - Deny fchdir out of chroot
++ - Priority restrictions in chroot
++ - Segmentation-based implementation of PaX
++ - Mprotect restrictions
++ - Removal of addresses from /proc/<pid>/[smaps|maps|stat]
++ - Kernel stack randomization

++ If you say Y here, /dev/kmem and /dev/mem won't be allowed to
++ be written to via mmap or otherwise to modify the running kernel.
++ /dev/port will also not be allowed to be opened. If you have module
++ support disabled, enabling this will close up four 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
++ 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
++ not be allowed to mprotect it with PROT_WRITE later.
++ It is highly recommended that you say Y here if you meet all the
++ conditions above.

++ If you say Y here, only processes with CAP_SYS_RAWIO will be able to
++ make use of a special execution mode on 32bit x86 processors called
++ Virtual 8086 (VM86) mode. XFree86 may need vm86 mode for certain
++ video cards and will still work with this option enabled. The purpose
++ of the option is to prevent exploitation of emulation errors in
++ virtualization of vm86 mode like the one discovered in VMWare in 2009.
++ Nearly all users should be able to enable this option.

++ If you say Y here, all ioperm and iopl calls will return an error.
++ Ioperm and iopl can be used to modify the running kernel.
++ Unfortunately, some programs need this access to operate properly,
++ the most notable of which are XFree86 and hwclock. hwclock can be
++ remedied by having RTC support in the kernel, so real-time
++ clock support is enabled if this option is enabled, to ensure
++ that hwclock operates correctly. XFree86 still will not
++ operate correctly with this option enabled, so DO NOT CHOOSE Y
++ IF YOU USE XFree86. If you use XFree86 and you still want to
++ protect your kernel against modification, use the RBAC system.

++ help
++ If you say Y here, the /proc/<pid>/maps and /proc/<pid>/stat files will
++ give no information about the addresses of its mappings if
++ PaX features that rely on random addresses are enabled on the task.
++ If you use PaX it is greatly recommended that you say Y here as it
++ closes up a hole that makes the full ASLR useless for suid
++ 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 will be deterred. When a child of a
++ forking daemon is killed by PaX or crashes due to an illegal
++ instruction, 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. It is recommended that you also
++ enable signal logging in the auditing section so that logs are
++ generated when a process performs an illegal instruction.
++
++config GRKERNSEC_MODHARDEN
++ bool "Harden module auto-loading"
++ depends on MODULES
++ 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

++ By design some architectures do not allow for protecting memory
++ pages against execution or even if they do, Linux does not make
++ use of this feature. In practice this means that if a page is
++ readable (such as the stack or heap) it is also executable.
++
++ There is a well known exploit technique that makes use of this
++ fact and a common programming mistake where an attacker can
++ introduce code of his choice somewhere in the attacked program's
++ memory (typically the stack or the heap) and then execute it.
++
++ If the attacked program was running with different (typically
++ higher) privileges than that of the attacker, then he can elevate
++ his own privilege level (e.g. get a root shell, write to files for
++ which he does not have write access to, etc).
++
++ Enabling this option will let you choose from various features
++ that prevent the injection and execution of 'foreign' code in
++ a program.
++
++ This will also break programs that rely on the old behaviour and

++
++config PAX_RANDMMAP

++ By saying Y here the kernel will use a randomized base address for

++ 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

naoki: Get rid of the toolchain.
Big changes in dependency resolution: Naoki does not resolve
dependencies of source packages anymore. It instead goes on
and checks out the available binary packages and tries to
build a one-time customized toolchain.
The toolchain was always a thing that made development slow
and caused lots of issues wo do not have anymore.
This references #53.

-+ On Gentoo
-+ Added a hack for gcc-specs-* in toolchain-funcs.eclass and _filter-hardened in flag-o-matic.eclass
-+ to support older hardened GCC patches and we don't need to change the code on gcc-specs-* and _filter-hardened.
-+ We use -fstack-protector-all instead of -fstack-protector
-+ This will add some unsupported upstream commands options as -nopie.
-+ -D__KERNEL__ is added so we don't have -fPIE and -fstack-protector-all when building kernels.
-+ ESP_CC1_SPEC is added to CC1_SPEC.
-+ -D_FORTIFY_SOURCES=2 is added with gentoo's patchset as default so no need to set it hear.
-+ ESP_LINK_SPEC will not add -z,relro as it default on with binutils.
-+ ESP_CC1_STRICT_SPEC is added so we don't use gcc/opts.c to disable it.
-+ ESP_OPTIONS_PIE_CHECK_SPEC check for -pie, -p, -pg, -profile, -static and -shared.
-+ ENABLE_CRTBEGINTS add support for crtbeginTS.o, build -static with -fPIE or -fpie.

-# DIY Linux Patch
-Date: 2008-09-09
-Author: Refer Origin.
-Origin: Partial revert of http://gcc.gnu.org/ml/gcc-cvs/2006-11/msg00416.html
-Maker: Greg Schafer <gschafer(a)zip.com.au>
-Upstream Status: Not applicable. Tweak only for Temptools phase GCC-Pass2.
-Description: Partially revert GCC driver to pre-GCC-4.3 state to allow startfiles to be
- found in $prefix when GCC is configured for a non-standard prefix eg: /temptools. Full
- background info in thread starting here: http://gcc.gnu.org/ml/gcc/2008-03/msg00095.html
- and GCC bugzilla here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35532

-+ We use -fstack-protector-all instead of -fstack-protector
-+ This will add some unsupported upstream commands options as -nopie.
-+ -D__KERNEL__ is added so we don't have -fPIE and -fstack-protector-all when building kernels.

-+ -D_FORTIFY_SOURCES=2 is added with gentoo's patchset as default so no need to set it hear.
-+ ESP_LINK_SPEC will not add -z,relro as it default on with binutils.
-+ ESP_CC1_STRICT_SPEC is added so we don't use gcc/opts.c to disable it.
-+ ESP_OPTIONS_PIE_CHECK_SPEC check for -pie, -p, -pg, -profile, -static and -shared.
