* Rename class_destroy to avoid namespace conflicts.James Morris2006-12-03
| | | | | | | | | | We're seeing increasing namespace conflicts between the global class_destroy() function declared in linux/device.h, and the private function in the SELinux core code.

* NetLabel: convert to an extensibile/sparse category bitmapPaul Moore2006-12-03
| | | | | | | | | | | | | | | | The original NetLabel category bitmap was a straight char bitmap which worked fine for the initial release as it only supported 240 bits due to limitations in the CIPSO restricted bitmap tag (tag type 0x01). This patch converts that straight char bitmap into an extensibile/sparse bitmap in order to lay the foundation for other CIPSO tag types and protocols. This patch also has a nice side effect in that all of the security attributes passed by NetLabel into the LSM are now in a format which is in the host's native byte/bit ordering which makes the LSM specific code much simpler; look at the changes in security/selinux/ss/ebitmap.c as an example.

* NetLabel: make netlbl_lsm_secattr struct easier/quicker to understandPaul Moore2006-12-03
| | | | | | | | | | | | | | | | | | | The existing netlbl_lsm_secattr struct required the LSM to check all of the fields to determine if any security attributes were present resulting in a lot of work in the common case of no attributes. This patch adds a 'flags' field which is used to indicate which attributes are present in the structure; this should allow the LSM to do a quick comparison to determine if the structure holds any security attributes.

* [SELinux]: Add support for DCCPJames Morris2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements SELinux kernel support for DCCP (http://linux-net.osdl.org/index.php/DCCP), which is similar in operation to TCP in terms of connected state between peers. The SELinux support for DCCP is thus modeled on existing handling of TCP. A new DCCP socket class is introduced, to allow protocol differentation. The permissions for this class inherit all of the socket permissions, as well as the current TCP permissions (node_bind, name_bind etc). IPv4 and IPv6 are supported, although labeled networking is not, at this stage. Patches for SELinux userspace are at: http://people.redhat.com/jmorris/selinux/dccp/user/ I've performed some basic testing, and it seems to be working as expected. Adding policy support is similar to TCP, the only real difference being that it's a different protocol.

* SELinux: Fix SA selection semanticsVenkat Yekkirala2006-12-03
| | | | | | | | | | | | | | | | | | | | | Fix the selection of an SA for an outgoing packet to be at the same context as the originating socket/flow. This eliminates the SELinux policy's ability to use/sendto SAs with contexts other than the socket's. With this patch applied, the SELinux policy will require one or more of the following for a socket to be able to communicate with/without SAs: 1. To enable a socket to communicate without using labeled-IPSec SAs: allow socket_t unlabeled_t:association { sendto recvfrom } 2.

* SELinux: Various xfrm labeling fixesVenkat Yekkirala2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the upstreaming of the mlsxfrm modification a few months back, testing has resulted in the identification of the following issues/bugs that are resolved in this patch set. 1. Fix the security context used in the IKE negotiation to be the context of the socket as opposed to the context of the SPD rule. 2. Fix SO_PEERSEC for tcp sockets to return the security context of the peer as opposed to the source. 3. Fix the selection of an SA for an outgoing packet to be at the same context as the originating socket/flow. The following would be the result of applying this patchset: - SO_PEERSEC will now correctly return the peer's context. - IKE deamons will receive the context of the source socket/flow as opposed to the SPD rule's context so that the negotiated SA will be at the same context as the source socket/flow. - The SELinux policy will require one or more of the following for a socket to be able to communicate with/without SAs: 1. To enable a socket to communicate without using labeled-IPSec SAs: allow socket_t unlabeled_t:association { sendto recvfrom } 2. To enable a socket to communicate with labeled-IPSec SAs: allow socket_t self:association { sendto }; allow socket_t peer_sa_t:association { recvfrom }; This Patch: Pass correct security context to IKE for use in negotiation Fix the security context passed to IKE for use in negotiation to be the context of the socket as opposed to the context of the SPD rule so that the SA carries the label of the originating socket/flow.

| * SELinux: validate kernel object classes and permissionsChad Sellers2006-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new object class and permission validation scheme that validates against the defined kernel headers. This scheme allows extra classes and permissions that do not conflict with the kernel definitions to be added to the policy. This validation is now done for all policy loads, not just subsequent loads after the first policy load. The implementation walks the three structrures containing the defined object class and permission values and ensures their values are the same in the policy being loaded. This includes verifying the object classes themselves, the permissions they contain, and the permissions they inherit from commons. Classes or permissions that are present in the kernel but missing from the policy cause a warning (printed to KERN_INFO) to be printed, but do not stop the policy from loading, emulating current behavior. Any other inconsistencies cause the load to fail. Signed-off-by: Chad Sellers <csellers@tresys.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: James Morris <jmorris@namei.org>

These functions include hash table function pointers hash_value and keycmp. The only implementations of these currently are symhash and symcmp, which do not modify the key. The key parameter should never be changed by any of these, so it should be const. This is necessary to allow calling these functions with keys found in kernel object class and permission definitions.

* [NetLabel]: protect the CIPSOv4 socket option from setsockopt()Paul Moore2006-10-30
| | | | | | | | | | | | | | | | This patch makes two changes to protect applications from either removing or tampering with the CIPSOv4 IP option on a socket. The first is the requirement that applications have the CAP_NET_RAW capability to set an IPOPT_CIPSO option on a socket; this prevents untrusted applications from setting their own CIPSOv4 security attributes on the packets they send. The second change is to SELinux and it prevents applications from setting any IPv4 options when there is an IPOPT_CIPSO option already present on the socket; this prevents applications from removing CIPSOv4 security attributes from the packets they send.

* SELinux: Bug fix in polidydb_destroyChad Sellers2006-10-12
| | | | | | | | | | | | | | | This patch fixes two bugs in policydb_destroy. Two list pointers (policydb.ocontexts[i] and policydb.genfs) were not being reset to NULL when the lists they pointed to were being freed. This caused a problem when the initial policy load failed, as the policydb being destroyed was not a temporary new policydb that was thrown away, but rather was the global (active) policydb. Consequently, later functions, particularly sys_bind->selinux_socket_bind->security_node_sid and do_rw_proc->selinux_sysctl->selinux_proc_get_sid->security_genfs_sid tried to dereference memory that had previously been freed.

* IPsec: correct semantics for SELinux policy matchingVenkat Yekkirala2006-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when an IPSec policy rule doesn't specify a security context, it is assumed to be "unlabeled" by SELinux, and so the IPSec policy rule fails to match to a flow that it would otherwise match to, unless one has explicitly added an SELinux policy rule allowing the flow to "polmatch" to the "unlabeled" IPSec policy rules. In the absence of such an explicitly added SELinux policy rule, the IPSec policy rule fails to match and so the packet(s) flow in clear text without the otherwise applicable xfrm(s) applied. The above SELinux behavior violates the SELinux security notion of "deny by default" which should actually translate to "encrypt by default" in the above case. This was first reported by Evgeniy Polyakov and the way James Morris was seeing the problem was when connecting via IPsec to a confined service on an SELinux box (vsftpd), which did not have the appropriate SELinux policy permissions to send packets via IPsec. With this patch applied, SELinux "polmatching" of flows Vs. IPSec policy rules will only come into play when there's a explicit context specified for the IPSec policy rule (which also means there's corresponding SELinux policy allowing appropriate domains/flows to polmatch to this context). Secondly, when a security module is loaded (in this case, SELinux), the security_xfrm_policy_lookup() hook can return errors other than access denied, such as -EINVAL. We were not handling that correctly, and in fact inverting the return logic and propagating a false "ok" back up to xfrm_lookup(), which then allowed packets to pass as if they were not associated with an xfrm policy. The solution for this is to first ensure that errno values are correctly propagated all the way back up through the various call chains from security_xfrm_policy_lookup(), and handled correctly. Then, flow_cache_lookup() is modified, so that if the policy resolver fails (typically a permission denied via the security module), the flow cache entry is killed rather than having a null policy assigned (which indicates that the packet can pass freely). This also forces any future lookups for the same flow to consult the security module (e.g. SELinux) for current security policy (rather than, say, caching the error on the flow cache entry). This patch: Fix the selinux side of things. This makes sure SELinux polmatching of flow contexts to IPSec policy rules comes into play only when an explicit context is associated with the IPSec policy rule. Also, this no longer defaults the context of a socket policy to the context of the socket since the "no explicit context" case is now handled properly.

* [PATCH] SELinux: support mls categories for context mountsCory Olmo2006-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allows commas to be embedded into context mount options (i.e. "-o context=some_selinux_context_t"), to better support multiple categories, which are separated by commas and confuse mount. For example, with the current code: mount -t iso9660 /dev/cdrom /media/cdrom -o \ ro,context=system_u:object_r:iso9660_t:s0:c1,c3,c4,exec The context option that will be interpreted by SELinux is context=system_u:object_r:iso9660_t:s0:c1 instead of context=system_u:object_r:iso9660_t:s0:c1,c3,c4 The options that will be passed on to the file system will be ro,c3,c4,exec. The proposed solution is to allow/require the SELinux context option specified to mount to use quotes when the context contains a comma. This patch modifies the option parsing in parse_opts(), contained in mount.c, to take options after finding a comma only if it hasn't seen a quote or if the quotes are matched. It also introduces a new function that will strip the quotes from the context option prior to translation. The quotes are replaced after the translation is completed to insure that in the event the raw context contains commas the kernel will be able to interpret the correct context.

* [NetLabel]: change the SELinux permissionsPaul Moore2006-09-25
| | | | | | | | | | Change NetLabel to use the 'recvfrom' socket permission and the SECINITSID_NETMSG SELinux SID as the NetLabel base SID for incoming packets. This patch effectively makes the old, and currently unused, SELinux NETMSG permissions NetLabel permissions. Signed-of-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

* [NetLabel]: correct improper handling of non-NetLabel peer contextsPaul Moore2006-09-25
| | | | | | | | | | | | Fix a problem where NetLabel would always set the value of sk_security_struct->peer_sid in selinux_netlbl_sock_graft() to the context of the socket, causing problems when users would query the context of the connection. This patch fixes this so that the value in sk_security_struct->peer_sid is only set when the connection is NetLabel based, otherwise the value is untouched.
