If the sysctl option is enabled, a sysctl -+ option with name "audit_textrel" is created. -+ -+endmenu -+ -+menu "Executable Protections" -+depends on GRKERNSEC -+ -+config GRKERNSEC_DMESG -+ bool "Dmesg(8) restriction" -+ default y if GRKERNSEC_CONFIG_AUTO -+ help -+ If you say Y here, non-root users will not be able to use dmesg(8) -+ to view the contents of the kernel's circular log buffer. -+ The kernel's log buffer often contains kernel addresses and other -+ identifying information useful to an attacker in fingerprinting a -+ system for a targeted exploit. -+ If the sysctl option is enabled, a sysctl option with name "dmesg" is -+ created. -+ -+config GRKERNSEC_HARDEN_PTRACE -+ bool "Deter ptrace-based process snooping" -+ default y if GRKERNSEC_CONFIG_AUTO -+ help -+ If you say Y here, TTY sniffers and other malicious monitoring -+ programs implemented through ptrace will be defeated. If you -+ have been using the RBAC system, this option has already been -+ enabled for several years for all users, with the ability to make -+ fine-grained exceptions. -+ -+ This option only affects the ability of non-root users to ptrace -+ processes that are not a descendent of the ptracing process. -+ This means that strace ./binary and gdb ./binary will still work, -+ but attaching to arbitrary processes will not.

This option is useful in environments that -+ remove the read bits (e.g. file mode 4711) from suid binaries to -+ prevent infoleaking of their contents. This option adds -+ consistency to the use of that file mode, as the binary could normally -+ be read out when run without privileges while ptracing. -+ -+ If the sysctl option is enabled, a sysctl option with name "ptrace_readexec" -+ is created. -+ -+config GRKERNSEC_SETXID -+ bool "Enforce consistent multithreaded privileges" -+ default y if GRKERNSEC_CONFIG_AUTO -+ depends on (X86 || SPARC64 || PPC || ARM || MIPS) -+ help -+ If you say Y here, a change from a root uid to a non-root uid -+ in a multithreaded application will cause the resulting uids, -+ gids, supplementary groups, and capabilities in that thread -+ to be propagated to the other threads of the process. In most -+ cases this is unnecessary, as glibc will emulate this behavior -+ on behalf of the application. Other libcs do not act in the -+ same way, allowing the other threads of the process to continue -+ running with root privileges.

If the sysctl option -+ is enabled, a sysctl option with name "tpe" is created. -+ -+config GRKERNSEC_TPE_ALL -+ bool "Partially restrict all non-root users" -+ depends on GRKERNSEC_TPE -+ help -+ If you say Y here, all non-root users will be covered under -+ a weaker TPE restriction. This is separate from, and in addition to, -+ the main TPE options that you have selected elsewhere. Thus, if a -+ "trusted" GID is chosen, this restriction applies to even that GID. -+ Under this restriction, all non-root users will only be allowed to -+ execute files in directories they own that are not group or -+ world-writable, or in directories owned by root and writable only by -+ root. If the sysctl option is enabled, a sysctl option with name -+ "tpe_restrict_all" is created. -+ -+config GRKERNSEC_TPE_INVERT -+ bool "Invert GID option" -+ depends on GRKERNSEC_TPE -+ help -+ If you say Y here, the group you specify in the TPE configuration will -+ decide what group TPE restrictions will be *disabled* for. This -+ option is useful if you want TPE restrictions to be applied to most -+ users on the system. If the sysctl option is enabled, a sysctl option -+ with name "tpe_invert" is created. Unlike other sysctl options, this -+ entry will default to on for backward-compatibility. -+ -+config GRKERNSEC_TPE_GID -+ int -+ default GRKERNSEC_TPE_UNTRUSTED_GID if (GRKERNSEC_TPE && !GRKERNSEC_TPE_INVERT) -+ default GRKERNSEC_TPE_TRUSTED_GID if (GRKERNSEC_TPE && GRKERNSEC_TPE_INVERT) -+ -+config GRKERNSEC_TPE_UNTRUSTED_GID -+ int "GID for TPE-untrusted users" -+ depends on GRKERNSEC_TPE && !GRKERNSEC_TPE_INVERT -+ default 1005 -+ help -+ Setting this GID determines what group TPE restrictions will be -+ *enabled* for.

Since several grsecurity -+ features use additional randomness, it is recommended that you say Y -+ here. Saying Y here has a similar effect as modifying -+ /proc/sys/kernel/random/poolsize. -+ -+config GRKERNSEC_BLACKHOLE -+ bool "TCP/UDP blackhole and LAST_ACK DoS prevention" -+ default y if GRKERNSEC_CONFIG_AUTO -+ depends on NET -+ help -+ If you say Y here, neither TCP resets nor ICMP -+ destination-unreachable packets will be sent in response to packets -+ 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 -+ "tcp_retries1" and "tcp_retries2". The default value of 4 -+ prevents a socket from lasting more than 45 seconds in LAST_ACK -+ state. -+ -+config GRKERNSEC_NO_SIMULT_CONNECT -+ bool "Disable TCP Simultaneous Connect" -+ default y if GRKERNSEC_CONFIG_AUTO -+ depends on NET -+ help -+ If you say Y here, a feature by Willy Tarreau will be enabled that -+ removes a weakness in Linux's strict implementation of TCP that -+ allows two clients to connect to each other without either entering -+ a listening state. The weakness allows an attacker to easily prevent -+ a client from connecting to a known server provided the source port -+ for the connection is guessed correctly. -+ -+ As the weakness could be used to prevent an antivirus or IPS from -+ fetching updates, or prevent an SSL gateway from fetching a CRL, -+ it should be eliminated by enabling this option. Though Linux is -+ one of few operating systems supporting simultaneous connect, it -+ has no legitimate use in practice and is rarely supported by firewalls. -+ -+config GRKERNSEC_SOCKET -+ bool "Socket restrictions" -+ depends on NET -+ help -+ If you say Y here, you will be able to choose from several options. -+ If you assign a GID on your system and add it to the supplementary -+ groups of users you want to restrict socket access to, this patch -+ will perform up to three things, based on the option(s) you choose. -+ -+config GRKERNSEC_SOCKET_ALL -+ bool "Deny any sockets to group" -+ depends on GRKERNSEC_SOCKET -+ help -+ If you say Y here, you will be able to choose a GID of whose users will -+ be unable to connect to other hosts from your machine or run server -+ applications from your machine.

If this option is enabled, all users in the group -+ you specify will have to use passive mode when initiating ftp transfers -+ from the shell on your machine.

You can echo values to files in /proc/sys/kernel/grsecurity -+ to enable (1) or disable (0) various features. All the sysctl entries -+ are mutable until the "grsec_lock" entry is set to a non-zero value. -+ All features enabled in the kernel configuration are disabled at boot -+ if you do not say Y to the "Turn on features by default" option. -+ All options should be set at startup, and the grsec_lock entry should -+ be set to a non-zero value after all the options are set. -+ *THIS IS EXTREMELY IMPORTANT* -+ -+config GRKERNSEC_SYSCTL_DISTRO -+ bool "Extra sysctl support for distro makers (READ HELP)" -+ depends on GRKERNSEC_SYSCTL && GRKERNSEC_IO -+ help -+ If you say Y here, additional sysctl options will be created -+ for features that affect processes running as root. Therefore, -+ it is critical when using this option that the grsec_lock entry be -+ enabled after boot. Only distros with prebuilt kernel packages -+ with this option enabled that can ensure grsec_lock is enabled -+ after boot should use this option. -+ *Failure to set grsec_lock after boot makes all grsec features -+ this option covers useless* -+ -+ Currently this option creates the following sysctl entries: -+ "Disable Privileged I/O": "disable_priv_io" -+ -+config GRKERNSEC_SYSCTL_ON -+ bool "Turn on features by default" -+ default y if GRKERNSEC_CONFIG_AUTO -+ depends on GRKERNSEC_SYSCTL -+ help -+ If you say Y here, instead of having all features enabled in the -+ kernel configuration disabled at boot time, the features will be -+ enabled at boot time. It is recommended you say Y here unless -+ there is some reason you would want all sysctl-tunable features to -+ be disabled by default. As mentioned elsewhere, it is important -+ to enable the grsec_lock entry once you have finished modifying -+ the sysctl entries. -+ -+endmenu -+menu "Logging Options" -+depends on GRKERNSEC -+ -+config GRKERNSEC_FLOODTIME -+ int "Seconds in between log messages (minimum)" -+ default 10 -+ help -+ This option allows you to enforce the number of seconds between -+ grsecurity log messages.

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 ++ "tcp_retries1" and "tcp_retries2".
