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.

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.

Setting its value to 1 will prevent any new ++ USB devices from being recognized by the OS. Any attempted USB ++ device insertion will be logged. This option is intended to be ++ used against custom USB devices designed to exploit vulnerabilities ++ in various USB device drivers. ++ ++ For greatest effectiveness, this sysctl should be set after any ++ relevant init scripts. This option is safe to enable in distros ++ as each user can choose whether or not to toggle the sysctl. ++ ++config GRKERNSEC_DENYUSB_FORCE ++ bool "Reject all USB devices not connected at boot" ++ select USB ++ depends on GRKERNSEC_DENYUSB ++ help ++ If you say Y here, a variant of GRKERNSEC_DENYUSB will be enabled ++ that doesn't involve a sysctl entry. This option should only be ++ enabled if you're sure you want to deny all new USB connections ++ at runtime and don't want to modify init scripts. This should not ++ be enabled by distros. It forces the core USB code to be built ++ into the kernel image so that all devices connected at boot time ++ can be recognized and new USB device connections can be prevented ++ prior to init running. ++ ++endmenu ++ ++menu "Sysctl Support" ++depends on GRKERNSEC && SYSCTL ++ ++config GRKERNSEC_SYSCTL ++ bool "Sysctl support" ++ default y if GRKERNSEC_CONFIG_AUTO ++ help ++ If you say Y here, you will be able to change the options that ++ grsecurity runs with at bootup, without having to recompile your ++ kernel. 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.

The ++ default should be suitable for most people, however if you find that ++ many of your logs are being interpreted as flooding, you may want to ++ raise this value. ++ ++ Setting both this value and GRKERNSEC_FLOODTIME to 0 will disable ++ any rate limiting on grsecurity log messages. ++ ++endmenu +diff --git a/grsecurity/Makefile b/grsecurity/Makefile +new file mode 100644 +index 0000000..30ababb +--- /dev/null ++++ b/grsecurity/Makefile +@@ -0,0 +1,54 @@ ++# grsecurity – access control and security hardening for Linux ++# All code in this directory and various hooks located throughout the Linux kernel are ++# Copyright (C) 2001-2014 Bradley Spengler, Open Source Security, Inc. ++# http://www.grsecurity.net spender@grsecurity.net ++# ++# This program is free software; you can redistribute it and/or ++# modify it under the terms of the GNU General Public License version 2 ++# as published by the Free Software Foundation. ++# ++# This program is distributed in the hope that it will be useful, ++# but WITHOUT ANY WARRANTY; without even the implied warranty of ++# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
