2006-09-22[NetLabel]: SELinux supportVenkat Yekkirala
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.

2006-09-22[NetLabel]: CIPSOv4 and Unlabeled packet integrationPaul Moore
Add CIPSO/IPv4 and unlabeled packet management to the NetLabel subsystem. The CIPSO/IPv4 changes allow the configuration of CIPSO/IPv4 within the overall NetLabel framework. The unlabeled packet changes allows NetLabel to pass unlabeled packets without error. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[NetLabel]: core NetLabel subsystemPaul Moore
Add a new kernel subsystem, NetLabel, to provide explicit packet labeling services (CIPSO, RIPSO, etc.) to LSM developers. NetLabel is designed to work in conjunction with a LSM to intercept and decode security labels on incoming network packets as well as ensure that outgoing network packets are labeled according to the security mechanism employed by the LSM. The NetLabel subsystem is configured through a Generic NETLINK interface described in the header files included in this patch. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[NetLabel]: CIPSOv4 enginePaul Moore
Add support for the Commercial IP Security Option (CIPSO) to the IPv4 network stack. CIPSO has become a de-facto standard for trusted/labeled networking amongst existing Trusted Operating Systems such as Trusted Solaris, HP-UX CMW, etc. This implementation is designed to be used with the NetLabel subsystem to provide explicit packet labeling to LSM developers. The CIPSO/IPv4 packet labeling works by the LSM calling a NetLabel API function which attaches a CIPSO label (IPv4 option) to a given socket; this in turn attaches the CIPSO label to every packet leaving the socket without any extra processing on the outbound side. On the inbound side the individual packet's sk_buff is examined through a call to a NetLabel API function to determine if a CIPSO/IPv4 label is present and if so the security attributes of the CIPSO label are returned to the caller of the NetLabel API function.

2006-09-22[MLSXFRM]: Fix build with SECURITY_NETWORK_XFRM disabled.Venkat Yekkirala
The following patch will fix the build problem (encountered by Andrew Morton) when SECURITY_NETWORK_XFRM is not enabled. As compared to git-net-selinux_xfrm_decode_session-build-fix.patch in -mm, this patch sets the return parameter sid to SECSID_NULL in selinux_xfrm_decode_session() and handles this value in the caller selinux_inet_conn_request() appropriately.

2006-09-22[MLSXFRM]: Auto-labeling of child socketsVenkat Yekkirala
This automatically labels the TCP, Unix stream, and dccp child sockets as well as openreqs to be at the same MLS level as the peer. This will result in the selection of appropriately labeled IPSec Security Associations. This also uses the sock's sid (as opposed to the isec sid) in SELinux enforcement of secmark in rcv_skb and postroute_last hooks.

2006-09-22[MLSXFRM]: Add security sid to sockVenkat Yekkirala
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.

2006-09-22[MLSXFRM]: Define new SELinux service routineVenkat Yekkirala
This defines a routine that combines the Type Enforcement portion of one sid with the MLS portion from the other sid to arrive at a new sid. This would be used to define a sid for a security association that is to be negotiated by IKE as well as for determing the sid for open requests and connection-oriented child sockets.

2006-09-22[MLSXFRM]: Granular IPSec associations for use in MLS environmentsVenkat Yekkirala
The current approach to labeling Security Associations for SELinux purposes uses a one-to-one mapping between xfrm policy rules and security associations. This doesn't address the needs of real world MLS (Multi-level System, traditional Bell-LaPadula) environments where a single xfrm policy rule (pertaining to a range, classified to secret for example) might need to map to multiple Security Associations (one each for classified, secret, top secret and all the compartments applicable to these security levels). This patch set addresses the above problem by allowing for the mapping of a single xfrm policy rule to multiple security associations, with each association used in the security context it is defined for. It also includes the security context to be used in IKE negotiation in the acquire messages sent to the IKE daemon so that a unique SA can be negotiated for each unique security context. A couple of bug fixes are also included; checks to make sure the SAs used by a packet match policy (security context-wise) on the inbound and also that the bundle used for the outbound matches the security context of the flow. This patch set also makes the use of the SELinux sid in flow cache lookups seemless by including the sid in the flow key itself. Also, open requests as well as connection-oriented child sockets are labeled automatically to be at the same level as the peer to allow for use of appropriately labeled IPSec associations. Description of changes: A "sid" member has been added to the flow cache key resulting in the sid being available at all needed locations and the flow cache lookups automatically using the sid. The flow sid is derived from the socket on the outbound and the SAs (unlabeled where an SA was not used) on the inbound. Outbound case: 1. Find policy for the socket. 2. OLD: Find an SA that matches the policy. NEW: Find an SA that matches BOTH the policy and the flow/socket. This is necessary since not every SA that matches the policy can be used for the flow/socket. Consider policy range Secret-TS, and SAs each for Secret and TS. We don't want a TS socket to use the Secret SA. Hence the additional check for the SA Vs. flow/socket. 3. NEW: When looking thru bundles for a policy, make sure the flow/socket can use the bundle. If a bundle is not found, create one, calling for IKE if necessary. If using IKE, include the security context in the acquire message to the IKE daemon. Inbound case: 1. OLD: Find policy for the socket. NEW: Find policy for the incoming packet based on the sid of the SA(s) it used or the unlabeled sid if no SAs were used. (Consider a case where a socket is "authorized" for two policies (unclassified-confidential, secret-top_secret). If the packet has come in using a secret SA, we really ought to be using the latter policy (secret-top_secret).) 2. OLD: BUG: No check to see if the SAs used by the packet agree with the policy sec_ctx-wise. (It was indicated in selinux_xfrm_sock_rcv_skb() that this was being accomplished by (x->id.spi == tmpl->id.spi || !tmpl->id.spi) in xfrm_state_ok, but it turns out tmpl->id.spi would normally be zero (unless xfrm policy rules specify one at the template level, which they usually don't). NEW: The socket is checked for access to the SAs used (based on the sid of the SAs) in selinux_xfrm_sock_rcv_skb(). Forward case: This would be Step 1 from the Inbound case, followed by Steps 2 and 3 from the Outbound case. Outstanding items/issues: - Timewait acknowledgements and such are generated in the current/upstream implementation using a NULL socket resulting in the any_socket sid (SYSTEM_HIGH) to be used. This problem is not addressed by this patch set. This patch: Add new flask definitions to SELinux Adds a new avperm "polmatch" to arbitrate flow/state access to a xfrm policy rule.

2006-09-22[POWERPC] Maple U3 HT - reject inappropriate config space accessNathan Lynch
When there is a PCI-X mode 2 capable device behind the HT<->PCI-X bridge, the pci core decides that the device has the extended 4K config space, even though the bus is not operating in mode 2. This is because the u3_ht pci ops silently accept offsets greater than 255 but use only the 8 least significant bits, which means reading at offset 0x100 gets the data at offset 0x0, and causes confusion for lspci. Reject accesses to configuration space offsets greater than 255. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Ulrich Weigand found a bug with the current version of the asm-powerpc/ptrace.h that prevents building at least the SPU target version of gdb, since some ptrace opcodes are not defined. The problem seems to have originated in the merging of 32 and 64 bit versions of that file, the problem is that some opcodes are only valid on 64 bit kernels, but are also used by 32 bit programs, so they can't depends on the __powerpc64__ symbol.

CC'ing some folks who might know better, based on the who-touched-it-last principle. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
