++ 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

++ If you say Y here, /dev/kmem and /dev/mem won't be allowed to

++ /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

++ 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

++ 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, as well as against suid/sgid binaries
++ will be deterred. When a child of a forking daemon is killed by PaX
++ or crashes due to an illegal instruction or other suspicious signal,
++ 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
++ processes terminated, and they are prevented from executing any further
++ processes for 15 minutes.
++ It is recommended that you also enable signal logging in the auditing
++ section so that logs are generated when a process triggers a suspicious
++ signal.
++
++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
++ 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"
++ 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.
++
++config GRKERNSEC_KERN_LOCKOUT
++ bool "Active kernel exploit response"
++ depends on X86
++ help
++ If you say Y here, when a PaX alert is triggered due to suspicious
++ 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.

++ of new vulnerabilities, ranging from infoleaks to local compromise.
++ There has been very little oversight with an eye toward security involved

++ 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
++ all servers it connects to have this option enabled, consider
++ disabling this feature on the haproxy host.
++
++ If the sysctl option is enabled, two sysctl options with names
++ "ip_blackhole" and "lastack_retries" will be created.
++ While "ip_blackhole" takes the standard zero/non-zero on/off
++ toggle, "lastack_retries" uses the same kinds of values as

+
+grsecurity contains a number of options which allow certain protections
+to be applied to or exempted from members of a given group. However, the
+default GIDs specified in the upstream patch are entirely arbitrary and
+there is no telling which (if any) groups the GIDs will correlate with
+on an end-user's system. Because some users don't pay a great deal of
+attention to the finer points of kernel configuration, it is probably
+wise to specify some reasonable defaults so as to stop careless users
+from shooting themselves in the foot.

+Add Hardened Gentoo [server/workstation] predefined grsecurity
+levels. They're designed to provide a comparitively high level of
+security while remaining generally suitable for as great a majority
+of the userbase as possible (particularly new users).
+
+Make Hardened Gentoo [workstation] predefined grsecurity level the
+default. The Hardened Gentoo [server] level is more restrictive
+and conflicts with some software and thus would be less suitable.
+
+The original version of this patch was conceived and created by:
+Ned Ludd <solar@gentoo.org>

+
+Dropping the patch, or simply fixing the #ifdef of the original patch

+No need to wrap vdso calls as gentoo does not use any version of

+
+COMPAT_VDSO is inappropriate for any modern Hardened Gentoo system. It
+conflicts with various parts of PaX, crashing the system if enabled
+while PaX's NOEXEC or UDEREF features are active. Moreover, it prevents
+a number of important PaX options from appearing in the configuration
+menu, including all PaX NOEXEC implementations. Unfortunately, the
+reason for the disappearance of these PaX configuration options is
+often far from obvious to inexperienced users.
+
+Therefore, we disable the COMPAT_VDSO menu entry entirely. However,
+COMPAT_VDSO operation can still be enabled via bootparam and sysctl
+interfaces. Consequently, we must also disable the ability to select
+COMPAT_VDSO operation at boot or runtime. Here we patch the kernel so
+that selecting COMPAT_VDSO operation at boot/runtime has no effect if
+conflicting PaX options are enabled, leaving VDSO_ENABLED operation
+intact.
