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!

NetLabel: SELinux cleanups This patch does a lot of cleanup in the SELinux NetLabel support code. A summary of the changes include: * Use RCU locking for the NetLabel state variable in the skk_security_struct instead of using the inode_security_struct mutex. * Remove unnecessary parameters in selinux_netlbl_socket_post_create(). * Rename selinux_netlbl_sk_clone_security() to selinux_netlbl_sk_security_clone() to better fit the other NetLabel sk_security functions. * Improvements to selinux_netlbl_inode_permission() to help reduce the cost of the common case.

[PATCH] keys: add a way to store the appropriate context for newly-created keys Add a /proc/<pid>/attr/keycreate entry that stores the appropriate context for newly-created keys. Modify the selinux_key_alloc hook to make use of the new entry. Update the flask headers to include a new "setkeycreate" permission for processes. Update the flask headers to include a new "create" permission for keys. Use the create permission to restrict which SIDs each task can assign to newly-created keys. Add a new parameter to the security hook "security_key_alloc" to indicate whether it is being invoked by the kernel, or from userspace. If it is being invoked by the kernel, the security hook should never fail. Update the documentation to reflect these changes.

[PATCH] SELinux: Add sockcreate node to procattr API Below is a patch to add a new /proc/self/attr/sockcreate A process may write a context into this interface and all subsequent sockets created will be labeled with that context. This is the same idea as the fscreate interface where a process can specify the label of a file about to be created. At this time one envisioned user of this will be xinetd. It will be able to better label sockets for the actual services. At this time all sockets take the label of the creating process, so all xinitd sockets would just be labeled the same. I tested this by creating a tcp sender and listener. The sender was able to write to this new proc file and then create sockets with the specified label. I am able to be sure the new label was used since the avc denial messages kicked out by the kernel included both the new security permission setsockcreate and all the socket denials were for the new label, not the label of the running process.

SELinux: Improve read/write performance It reduces the selinux overhead on read/write by only revalidating permissions in selinux_file_permission if the task or inode labels have changed or the policy has changed since the open-time check. A new LSM hook, security_dentry_open, is added to capture the necessary state at open time to allow this optimization.

[PATCH] SELinux: decouple fscontext/context mount options Remove the conflict between fscontext and context mount options. If context= is specified without fscontext it will operate just as before, if both are specified we will use mount point labeling and all inodes will get the label specified by context=.

Security: add get, set, and cloning of superblock security information Adds security_get_sb_mnt_opts, security_set_sb_mnt_opts, and security_clont_sb_mnt_opts to the LSM and to SELinux. This will allow filesystems to directly own and control all of their mount options if they so choose. This interface deals only with option identifiers and strings so it should generic enough for any LSM which may come in the future. Filesystems which pass text mount data around in the kernel (almost all of them) need not currently make use of this interface when dealing with SELinux since it will still parse those strings as it always has. I assume future LSM's would do the same. NFS is the primary FS which does not use text mount data and thus must make use of this interface. An LSM would need to implement these functions only if they had mount time options, such as selinux has context= or fscontext=. If the LSM has no mount time options they could simply not implement and let the dummy ops take care of things. An LSM other than SELinux would need to define new option numbers in security.h and any FS which decides to own there own security options would need to be patched to use this new interface for every possible LSM. This is because it was stated to me very clearly that LSM's should not attempt to understand FS mount data and the burdon to understand security should be in the FS which owns the options.

SELinux: Convert the netif code to use ifindex values The current SELinux netif code requires the caller have a valid net_device struct pointer to lookup network interface information. However, we don't always have a valid net_device pointer so convert the netif code to use the ifindex values we always have as part of the sk_buff. This patch also removes the default message SID from the network interface record, it is not being used and therefore is "dead code".

[MLSXFRM]: Add security sid to sock This adds security for IP sockets at the sock level. Security at the sock level is needed to enforce the SELinux security policy for security associations even when a sock is orphaned (such as in the TCP LAST_ACK state). This will also be used to enforce SELinux controls over data arriving at or leaving a child socket while it's still waiting to be accepted.

[NetLabel]: SELinux support Add NetLabel support to the SELinux LSM and modify the socket_post_create() LSM hook to return an error code. The most significant part of this patch is the addition of NetLabel hooks into the following SELinux LSM hooks: * selinux_file_permission() * selinux_socket_sendmsg() * selinux_socket_post_create() * selinux_socket_sock_rcv_skb() * selinux_socket_getpeersec_stream() * selinux_socket_getpeersec_dgram() * selinux_sock_graft() * selinux_inet_conn_request() The basic reasoning behind this patch is that outgoing packets are "NetLabel'd" by labeling their socket and the NetLabel security attributes are checked via the additional hook in selinux_socket_sock_rcv_skb(). NetLabel itself is only a labeling mechanism, similar to filesystem extended attributes, it is up to the SELinux enforcement mechanism to perform the actual access checks. In addition to the changes outlined above this patch also includes some changes to the extended bitmap (ebitmap) and multi-level security (mls) code to import and export SELinux TE/MLS attributes into and out of NetLabel.

SELinux: Better integration between peer labeling subsystems Rework the handling of network peer labels so that the different peer labeling subsystems work better together. This includes moving both subsystems to a single "peer" object class which involves not only changes to the permission checks but an improved method of consolidating multiple packet peer labels.
