selinux: Remove unused permission definitions

2015-06-04T20:22:17+00:00

Remove unused permission definitions from SELinux. Many of these were only ever used in pre-mainline versions of SELinux, prior to Linux 2.6.0. Some of them were used in the legacy network or compat_net=1 checks that were disabled by default in Linux 2.6.18 and fully removed in Linux 2.6.30. Permissions never used in mainline Linux: file swapon filesystem transition tcp_socket { connectto newconn acceptfrom } node enforce_dest unix_stream_socket { newconn acceptfrom } Legacy network checks, removed in 2.6.30: socket { recv_msg send_msg } node { tcp_recv tcp_send udp_recv udp_send rawip_recv rawip_send dccp_recv dccp_send } netif { tcp_recv tcp_send udp_recv udp_send rawip_recv rawip_send dccp_recv dccp_send } Signed-off-by: Stephen Smalley Signed-off-by: Paul Moore

selinux: update netlink socket classes

2015-06-04T20:22:16+00:00

Update the set of SELinux netlink socket class definitions to match the set of netlink protocols implemented by the kernel. The ip_queue implementation for the NETLINK_FIREWALL and NETLINK_IP6_FW protocols was removed in d16cf20e2f2f13411eece7f7fb72c17d141c4a84, so we can remove the corresponding class definitions as this is dead code. Add new classes for NETLINK_ISCSI, NETLINK_FIB_LOOKUP, NETLINK_CONNECTOR, NETLINK_NETFILTER, NETLINK_GENERIC, NETLINK_SCSITRANSPORT, NETLINK_RDMA, and NETLINK_CRYPTO so that we can distinguish among sockets created for each of these protocols. This change does not define the finer-grained nlsmsg_read/write permissions or map specific nlmsg_type values to those permissions in the SELinux nlmsgtab; if finer-grained control of these sockets is desired/required, that can be added as a follow-on change. We do not define a SELinux class for NETLINK_ECRYPTFS as the implementation was removed in 624ae5284516870657505103ada531c64dba2a9a. Signed-off-by: Stephen Smalley Signed-off-by: Paul Moore

Add security hooks to binder and implement the hooks for SELinux.

2015-01-25T17:17:57+00:00

Add security hooks to the binder and implement the hooks for SELinux. The security hooks enable security modules such as SELinux to implement controls over binder IPC. The security hooks include support for controlling what process can become the binder context manager (binder_set_context_mgr), controlling the ability of a process to invoke a binder transaction/IPC to another process (binder_transaction), controlling the ability of a process to transfer a binder reference to another process (binder_transfer_binder), and controlling the ability of a process to transfer an open file to another process (binder_transfer_file). These hooks have been included in the Android kernel trees since Android 4.3. (Updated to reflect upstream relocation and changes to the binder driver, changes to the LSM audit data structures, coding style cleanups, and to add inline documentation for the hooks).

audit: add netlink audit protocol bind to check capabilities on multicast join

2014-04-23T01:42:27+00:00

Register a netlink per-protocol bind fuction for audit to check userspace process capabilities before allowing a multicast group connection. Signed-off-by: Richard Guy Briggs Signed-off-by: David S. Miller

selinux: add the "attach_queue" permission to the "tun_socket" class

2013-01-14T23:16:59+00:00

Add a new permission to align with the new TUN multiqueue support, "tun_socket:attach_queue".

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security

2012-07-18T20:42:44+00:00

Pull SELinux regression fixes from James Morris. Andrew Morton has a box that hit that open perms problem. I also renamed the "epollwakeup" selinux name for the new capability to be "block_suspend", to match the rename done by commit d9914cf66181 ("PM: Rename CAP_EPOLLWAKEUP to CAP_BLOCK_SUSPEND"). * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: SELinux: do not check open perms if they are not known to policy SELinux: include definition of new capabilities

SELinux: include definition of new capabilities

2012-07-16T01:40:31+00:00

The kernel has added CAP_WAKE_ALARM and CAP_EPOLLWAKEUP. We need to define these in SELinux so they can be mediated by policy. Signed-off-by: Eric Paris Signed-off-by: James Morris

SELinux: Auto-generate security_is_socket_class

2011-03-03T20:19:43+00:00

The security_is_socket_class() is auto-generated by genheaders based on classmap.h to reduce maintenance effort when a new class is defined in SELinux kernel. The name for any socket class should be suffixed by "socket" and doesn't contain more than one substr of "socket". Signed-off-by: Harry Ciao Signed-off-by: Eric Paris Acked-by: Stephen Smalley

These permissions are not used and can be dropped in the kernel definitions. Suggested-by: Stephen Smalley Signed-off-by: Eric Paris Acked-by: Stephen Smalley

security: Define CAP_SYSLOG

2010-11-28T21:35:12+00:00

Privileged syslog operations currently require CAP_SYS_ADMIN. Split this off into a new CAP_SYSLOG privilege which we can sanely take away from a container through the capability bounding set. With this patch, an lxc container can be prevented from messing with the host's syslog (i.e. dmesg -c).
