Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] selinux: require AUDIT Make SELinux depend on AUDIT as it requires the basic audit support to log permission denials at all. Note that AUDITSYSCALL remains optional for SELinux, although it can be useful in providing further information upon denials.

[SECMARK]: Add new packet controls to SELinux Add new per-packet access controls to SELinux, replacing the old packet controls. Packets are labeled with the iptables SECMARK and CONNSECMARK targets, then security policy for the packets is enforced with these controls. To allow for a smooth transition to the new controls, the old code is still present, but not active by default. To restore previous behavior, the old controls may be activated at runtime by writing a '1' to /selinux/compat_net, and also via the kernel boot parameter selinux_compat_net. Switching between the network control models requires the security load_policy permission. The old controls will probably eventually be removed and any continued use is discouraged. With this patch, the new secmark controls for SElinux are disabled by default, so existing behavior is entirely preserved, and the user is not affected at all. It also provides a config option to enable the secmark controls by default (which can always be overridden at boot and runtime). It is also noted in the kconfig help that the user will need updated userspace if enabling secmark controls for SELinux and that they'll probably need the SECMARK and CONNMARK targets, and conntrack protocol helpers, although such decisions are beyond the scope of kernel configuration.

default n
help
This selects NSA Security-Enhanced Linux (SELinux).
You will also need a policy configuration and a labeled filesystem.
If you are unsure how to answer this question, answer N.
config SECURITY_SELINUX_BOOTPARAM
bool "NSA SELinux boot parameter"
depends on SECURITY_SELINUX
default n
help
This option adds a kernel parameter 'selinux', which allows SELinux
to be disabled at boot. If this option is selected, SELinux
functionality can be disabled with selinux=0 on the kernel
command line. The purpose of this option is to allow a single
kernel image to be distributed with SELinux built in, but not
necessarily enabled.
If you are unsure how to answer this question, answer N.
config SECURITY_SELINUX_BOOTPARAM_VALUE
int "NSA SELinux boot parameter default value"
depends on SECURITY_SELINUX_BOOTPARAM
range 0 1
default 1
help
This option sets the default value for the kernel parameter
'selinux', which allows SELinux to be disabled at boot. If this
option is set to 0 (zero), the SELinux kernel parameter will
default to 0, disabling SELinux at bootup. If this option is
set to 1 (one), the SELinux kernel parameter will default to 1,
enabling SELinux at bootup.
If you are unsure how to answer this question, answer 1.
config SECURITY_SELINUX_DISABLE
bool "NSA SELinux runtime disable"
depends on SECURITY_SELINUX
default n
help
This option enables writing to a selinuxfs node 'disable', which
allows SELinux to be disabled at runtime prior to the policy load.
SELinux will then remain disabled until the next boot.
This option is similar to the selinux=0 boot parameter, but is to
support runtime disabling of SELinux, e.g. from /sbin/init, for
portability across platforms where boot parameters are difficult
to employ.
If you are unsure how to answer this question, answer N.
config SECURITY_SELINUX_DEVELOP
bool "NSA SELinux Development Support"
depends on SECURITY_SELINUX
default y
help
This enables the development support option of NSA SELinux,
which is useful for experimenting with SELinux and developing
policies. If unsure, say Y. With this option enabled, the
kernel will start in permissive mode (log everything, deny nothing)
unless you specify enforcing=1 on the kernel command line. You
can interactively toggle the kernel between enforcing mode and
permissive mode (if permitted by the policy) via /selinux/enforce.
config SECURITY_SELINUX_AVC_STATS
bool "NSA SELinux AVC Statistics"
depends on SECURITY_SELINUX
default y
help
This option collects access vector cache statistics to
/selinux/avc/cache_stats, which may be monitored via
tools such as avcstat.

help
This option sets the default value for the 'checkreqprot' flag
that determines whether SELinux checks the protection requested
by the application or the protection that will be applied by the
kernel (including any implied execute for read-implies-exec) for
mmap and mprotect calls. If this option is set to 0 (zero),
SELinux will default to checking the protection that will be applied
by the kernel. If this option is set to 1 (one), SELinux will
default to checking the protection requested by the application.
The checkreqprot flag may be changed from the default via the
'checkreqprot=' boot parameter. It may also be changed at runtime
via /selinux/checkreqprot if authorized by policy.
