++	  If you say Y here, many of the features of grsecurity will be
++	  enabled, which will protect you against many kinds of attacks
++	  against your system.  The heightened security comes at a cost
++	  of an increased chance of incompatibilities with rare software
++	  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 group wheel (GID 10).  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

++	  include TPE, socket restrictions, and the sysctl system for
++	  grsecurity.  It is advised that you read through the help for
++	  each option to determine its usefulness in your situation.

++config GRKERNSEC_KMEM
++	bool "Deny writing to /dev/kmem, /dev/mem, and /dev/port"
++	help
++	  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 ACL 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.
++	  Enabling this feature could make certain apps like VMWare stop working,
++	  as they need to write to other locations in /dev/mem.
++	  It is highly recommended that you say Y here if you meet all the
++	  conditions above.

++	select RTC
++	help
++	  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 CONFIG_RTC 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 ACL system.
++
++config GRKERNSEC_PROC_MEMMAP
++	bool "Remove addresses from /proc/<pid>/[maps|stat]"
++	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_HIDESYM
++	bool "Hide kernel symbols"
++	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.  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 ACL system and hiding other files such as your
++	     kernel image and System.map
++	  3) You have the additional /proc restrictions enabled, which removes
++	     /proc/kcore
++	  If the above conditions are met, this option will aid to provide a
++	  useful protection against local and remote kernel exploitation of
++	  overflows and arbitrary read/write vulnerabilities.

++	  view all processes and files normally restricted to root if you choose
++	  the "restrict to user only" option.  NOTE: If you're running identd as

++
++config GRKERNSEC_LINK

++	  If you say Y here, /tmp race exploits will be prevented, since users
++	  will no longer be able to follow symlinks owned by other users in
++	  world-writable +t directories (i.e. /tmp), unless the owner of the

++	  enabled, a sysctl option with name "linking_restrictions" is created.
++
++config GRKERNSEC_FIFO
++	bool "FIFO restrictions"
++	help
++	  If you say Y here, users will not be able to write to FIFOs they don't
++	  own in world-writable +t directories (i.e. /tmp), unless the owner of
++	  the FIFO is the same owner of the directory it's held in.  If the sysctl
++	  option is enabled, a sysctl option with name "fifo_restrictions" is
++	  created.
++
++config GRKERNSEC_CHROOT
++	bool "Chroot jail restrictions"
++	help
++	  If you say Y here, you will be able to choose several options that will
++	  make breaking out of a chrooted jail much more difficult.  If you
++	  encounter no software incompatibilities with the following options, it
++	  is recommended that you enable each one.
++
++config GRKERNSEC_CHROOT_MOUNT
++	bool "Deny mounts"
++	depends on GRKERNSEC_CHROOT
++	help
++	  If you say Y here, processes inside a chroot will not be able to

++
++config GRKERNSEC_CHROOT_DOUBLE
++	bool "Deny double-chroots"
++	depends on GRKERNSEC_CHROOT
++	help
++	  If you say Y here, processes inside a chroot will not be able to chroot
++	  again outside the chroot.  This is a widely used method of breaking
++	  out of a chroot jail and should not be allowed.  If the sysctl 
++	  option is enabled, a sysctl option with name 
++	  "chroot_deny_chroot" is created.
++
++config GRKERNSEC_CHROOT_PIVOT
++	bool "Deny pivot_root in chroot"
++	depends on GRKERNSEC_CHROOT
++	help
++	  If you say Y here, processes inside a chroot will not be able to use
++	  a function called pivot_root() that was introduced in Linux 2.3.41.  It
++	  works similar to chroot in that it changes the root filesystem.  This
++	  function could be misused in a chrooted process to attempt to break out
++	  of the chroot, and therefore should not be allowed.  If the sysctl
++	  option is enabled, a sysctl option with name "chroot_deny_pivot" is
++	  created.
++
++config GRKERNSEC_CHROOT_CHDIR
++	bool "Enforce chdir(\"/\") on all chroots"
++	depends on GRKERNSEC_CHROOT
++	help
++	  If you say Y here, the current working directory of all newly-chrooted
++	  applications will be set to the the root directory of the chroot.
++	  The man page on chroot(2) states:
++	  Note that this call does not change  the  current  working
++	  directory,  so  that `.' can be outside the tree rooted at
++	  `/'.  In particular, the  super-user  can  escape  from  a
++	  `chroot jail' by doing `mkdir foo; chroot foo; cd ..'.
++
++	  It is recommended that you say Y here, since it's not known to break
++	  any software.  If the sysctl option is enabled, a sysctl option with
++	  name "chroot_enforce_chdir" is created.
++
++config GRKERNSEC_CHROOT_CHMOD

++	depends on GRKERNSEC_CHROOT
++	help
++	  If you say Y here, processes inside a chroot will not be able to chmod
++	  or fchmod files to make them have suid or sgid bits.  This protects
++	  against another published method of breaking a chroot.  If the sysctl

++	help
++	  If you say Y here, a well-known method of breaking chroots by fchdir'ing
++	  to a file descriptor of the chrooting process that points to a directory
++	  outside the filesystem will be stopped.  If the sysctl option
++	  is enabled, a sysctl option with name "chroot_deny_fchdir" is created.
++
++config GRKERNSEC_CHROOT_MKNOD
++	bool "Deny mknod"
++	depends on GRKERNSEC_CHROOT
++	help
++	  If you say Y here, processes inside a chroot will not be allowed to
++	  mknod.  The problem with using mknod inside a chroot is that it
++	  would allow an attacker to create a device entry that is the same
++	  as one on the physical root of your system, which could range from
++	  anything from the console device to a device for your harddrive (which
++	  they could then use to wipe the drive or steal data).  It is recommended
++	  that you say Y here, unless you run into software incompatibilities.
++	  If the sysctl option is enabled, a sysctl option with name

++	  processes outside the chroot.  This provides more security than simply
++	  removing CAP_SYS_NICE from the process' capability set.  If the

++	  is created.
++
++config GRKERNSEC_CHROOT_SYSCTL

++	  is therefore left as an option.  If the sysctl option is enabled, a

++	help
++	  If you say Y here, creation and removal of message queues, semaphores,
++	  and shared memory will be logged.  If the sysctl option is enabled, a
++	  sysctl option with name "audit_ipc" is created.
++
++config GRKERNSEC_SIGNAL
++	bool "Signal logging"
++	help
++	  If you say Y here, certain important signals will be logged, such as
++	  SIGSEGV, which will as a result inform you of when a error in a program
++	  occurred, which in some cases could mean a possible exploit attempt.
++	  If the sysctl option is enabled, a sysctl option with name
++	  "signal_logging" is created.
++
++config GRKERNSEC_FORKFAIL
++	bool "Fork failure logging"
++	help
++	  If you say Y here, all failed fork() attempts will be logged.
++	  This could suggest a fork bomb, or someone attempting to overstep

++	  with name "forkfail_logging" is created.
++

++
++config GRKERNSEC_PROC_IPADDR
++	bool "/proc/<pid>/ipaddr support"
++	help
++	  If you say Y here, a new entry will be added to each /proc/<pid>
++	  directory that contains the IP address of the person using the task.
++	  The IP is carried across local TCP and AF_UNIX stream sockets.
++	  This information can be useful for IDS/IPSes to perform remote response
++	  to a local attack.  The entry is readable by only the owner of the
++	  process (and root if he has CAP_DAC_OVERRIDE, which can be removed via
++	  the RBAC system), and thus does not create privacy concerns.
++
++config GRKERNSEC_AUDIT_TEXTREL
++	bool 'ELF text relocations logging (READ HELP)'
++	depends on PAX_MPROTECT
++	help
++	  If you say Y here, text relocations will be logged with the filename
++	  of the offending library or binary.  The purpose of the feature is
++	  to help Linux distribution developers get rid of libraries and
++	  binaries that need text relocations which hinder the future progress
++	  of PaX.  Only Linux distribution developers should say Y here, and
++	  never on a production machine, as this option creates an information
++	  leak that could aid an attacker in defeating the randomization of
++	  a single memory region.  If the sysctl option is enabled, a sysctl
++	  option with name "audit_textrel" is created.

++
++config GRKERNSEC_RANDPID
++	bool "Randomized PIDs"
++	help
++	  If you say Y here, all PIDs created on the system will be
++	  pseudo-randomly generated.  This is extremely effective along
++	  with the /proc restrictions to disallow an attacker from guessing
++	  pids of daemons, etc.  PIDs are also used in some cases as part
++	  of a naming system for temporary files, so this option would keep
++	  those filenames from being predicted as well.  We also use code
++	  to make sure that PID numbers aren't reused too soon.  If the sysctl

++	bool "Truly random TCP ISN selection"
++	help
++	  If you say Y here, Linux's default selection of TCP Initial Sequence
++	  Numbers (ISNs) will be replaced with that of OpenBSD.  Linux uses
++	  an MD4 hash based on the connection plus a time value to create the
++	  ISN, while OpenBSD's selection is random.  If the sysctl option is
++	  enabled, a sysctl option with name "rand_isns" is created.
++
++config GRKERNSEC_RANDID
++	bool "Randomized IP IDs"
++	help
++	  If you say Y here, all the id field on all outgoing packets
++	  will be randomized.  This hinders os fingerprinters and
++	  keeps your machine from being used as a bounce for an untraceable
++	  portscan.  Ids are used for fragmented packets, fragments belonging
++	  to the same packet have the same id.  By default linux only
++	  increments the id value on each packet sent to an individual host.
++	  We use a port of the OpenBSD random ip id code to achieve the
++	  randomness, while keeping the possibility of id duplicates to
++	  near none.  If the sysctl option is enabled, a sysctl option with name

++	  If you say Y here, the method of determining XIDs for RPC requests will

++	  incrementing the XID.  If you want your RPC connections to be more
++	  secure, say Y here.  If the sysctl option is enabled, a sysctl option

++	  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

++

++	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.
++
++	  NOTE: you can use the 'chpax' or 'paxctl' utilities to control
++	  this feature on a per file basis.
++
++config PAX_RANDKSTACK
++	bool "Randomize kernel stack base"
++	depends on PAX_ASLR && X86_TSC && !X86_64
++	help
++	  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
++	  stack.  The 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).
++	  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 .
++
++	  NOTE: you can use the 'chpax' or 'paxctl' utilities to control this
++	  feature on a per file basis.
++
++config PAX_RANDEXEC
++	bool "Randomize ET_EXEC base"
++	depends on PAX_MPROTECT && PAX_RANDMMAP
++	help
++	  By saying Y here the kernel will randomize the base address of normal
++	  ET_EXEC ELF executables as well.  This is accomplished by mapping the
++	  executable in memory in a special way which also allows for detecting
++	  attackers who attempt to execute its code for their purposes.  Since
++	  this special mapping causes performance degradation and the attack
++	  detection may create false alarms as well, you should carefully test
++	  your executables when this feature is enabled.
++
++	  This solution is intended only as a temporary one until you relink
++	  your programs as a dynamic ELF file.
++
++	  NOTE: you can use the 'chpax' or 'paxctl' utilities to control this
++	  feature on a per file basis.

++	help
++	  The Linux 2.6 kernel introduced a new feature that speeds up or
++	  simplifies certain operations, such as system calls or returns
++	  from signal handlers.
++
++	  Unfortunately the implementation also gives a powerful instrument
++	  into the hands of exploit writers: the so-called vsyscall page exists
++	  in every task at the same fixed address and it contains machine code
++	  that is very useful in performing the return-to-libc style attack.
++
++	  Since this exploit technique cannot in general be protected against
++	  via kernel solutions, this option will allow you to disable the use
