2015-10-22selinux: change CONFIG_SECURITY_SELINUX_CHECKREQPROT_VALUE defaultPaul Moore1-2/+2
Change the SELinux checkreqprot default value to 0 so that SELinux performs access control checking on the actual memory protections used by the kernel and not those requested by the application. Signed-off-by: Paul Moore <pmoore@redhat.com>
2008-12-31selinux: Deprecate and schedule the removal of the the compat_net functionalityPaul Moore1-27/+0
This patch is the first step towards removing the old "compat_net" code from the kernel. Secmark, the "compat_net" replacement was first introduced in 2.6.18 (September 2006) and the major Linux distributions with SELinux support have transitioned to Secmark so it is time to start deprecating the "compat_net" mechanism. Testing a patched version of 2.6.28-rc6 with the initial release of Fedora Core 5 did not show any problems when running in enforcing mode. This patch adds an entry to the feature-removal-schedule.txt file and removes the SECURITY_SELINUX_ENABLE_SECMARK_DEFAULT configuration option, forcing Secmark on by default although it can still be disabled at runtime. The patch also makes the Secmark permission checks "dynamic" in the sense that they are only executed when Secmark is configured; this should help prevent problems with older distributions that have not yet migrated to Secmark.

2008-04-18selinux: introduce permissive typesEric Paris1-1/+1
Introduce the concept of a permissive type. A new ebitmap is introduced to the policy database which indicates if a given type has the permissive bit set or not. This bit is tested for the scontext of any denial. The bit is meaningless on types which only appear as the target of a decision and never the source. A domain running with a permissive type will be allowed to perform any action similarly to when the system is globally set permissive.

2008-01-30SELinux: Add a capabilities bitmap to SELinux policy version 22Paul Moore1-1/+1
Add a new policy capabilities bitmap to SELinux policy version 22. This bitmap will enable the security server to query the policy to determine which features it supports. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>

2006-09-26[PATCH] selinux: add support for range transitions on object classesDarrel Goeddel1-1/+1
Introduces support for policy version 21. This version of the binary kernel policy allows for defining range transitions on security classes other than the process security class. As always, backwards compatibility for older formats is retained. The security class is read in as specified when using the new format, while the "process" security class is assumed when using an older policy format.

2006-06-18[SECMARK]: Add new packet controls to SELinuxJames Morris1-0/+29
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.

2006-02-08[PATCH] selinux: require AUDITStephen Smalley1-1/+1
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.

2006-02-05[PATCH] selinux: require SECURITY_NETWORKStephen Smalley1-1/+1

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+97
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!
