Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

When devfs cloning takes place, provide access to the credential of the process that caused the clone event to take place for the device driver creating the device. This allows cloned device drivers to adapt the device node based on security aspects of the process, such as the uid, gid, and MAC label. - Add a cred reference to struct cdev, so that when a device node is instantiated as a vnode, the cloning credential can be exposed to MAC. - Add make_dev_cred(), a version of make_dev() that additionally accepts the credential to stick in the struct cdev. Implement it and make_dev() in terms of a back-end make_dev_credv(). - Add a new event handler, dev_clone_cred, which can be registered to receive the credential instead of dev_clone, if desired. - Modify the MAC entry point mac_create_devfs_device() to accept an optional credential pointer (may be NULL), so that MAC policies can inspect and act on the label or other elements of the credential when initializing the skeleton device protections. - Modify tty_pty.c to register clone_dev_cred and invoke make_dev_cred(), so that the pty clone credential is exposed to the MAC Framework. While currently primarily focussed on MAC policies, this change is also a prerequisite for changes to allow ptys to be instantiated with the UID of the process looking up the pty. This requires further changes to the pty driver -- in particular, to immediately recycle pty nodes on last close so that the credential-related state can be recreated on next lookup.

Introduce a MAC label reference in 'struct inpcb', which caches the MAC label referenced from 'struct socket' in the IPv4 and IPv6-based protocols. This permits MAC labels to be checked during network delivery operations without dereferencing inp->inp_socket to get to so->so_label, which will eventually avoid our having to grab the socket lock during delivery at the network layer. This change introduces 'struct inpcb' as a labeled object to the MAC Framework, along with the normal circus of entry points: initialization, creation from socket, destruction, as well as a delivery access control check. For most policies, the inpcb label will simply be a cache of the socket label, so a new protocol switch method is introduced, pr_sosetlabel() to notify protocols that the socket layer label has been updated so that the cache can be updated while holding appropriate locks. Most protocols implement this using pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use the the worker function in_pcbsosetlabel(), which calls into the MAC Framework to perform a cache update. Biba, LOMAC, and MLS implement these entry points, as do the stub policy, and test policy. Reviewed by: sam, bms Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

Coalesce pipe allocations and frees. Previously, the pipe code would allocate two 'struct pipe's from the pipe zone, and malloc a mutex. - Create a new "struct pipepair" object holding the two 'struct pipe' instances, struct mutex, and struct label reference. Pipe structures now have a back-pointer to the pipe pair, and a 'pipe_present' flag to indicate whether the half has been closed. - Perform mutex init/destroy in zone init/destroy, avoiding reallocating the mutex for each pipe. Perform most pipe structure setup in zone constructor. - VM memory mappings for pageable buffers are still done outside of the UMA zone. - Change MAC API to speak 'struct pipepair' instead of 'struct pipe', update many policies. MAC labels are also handled outside of the UMA zone for now. Label-only policy modules don't have to be recompiled, but if a module is recompiled, its pipe entry points will need to be updated. If a module actually reached into the pipe structures (unlikely), that would also need to be modified. These changes substantially simplify failure handling in the pipe code as there are many fewer possible failure modes. On half-close, pipes no longer free the 'struct pipe' for the closed half until a full-close takes place. However, VM mapped buffers are still released on half-close. Some code refactoring is now possible to clean up some of the back references, etc; this patch attempts not to change the structure of most of the pipe implementation, only allocation/free code paths, so as to avoid introducing bugs (hopefully). This cuts about 8%-9% off the cost of sequential pipe allocation and free in system call tests on UP and SMP in my micro-benchmarks. May or may not make a difference in macro-benchmarks, but doing less work is good. Reviewed by: juli, tjr Testing help: dwhite, fenestro, scottl, et al

Redesign the externalization APIs from the MAC Framework to the MAC policy modules to improve robustness against C string bugs and vulnerabilities. Following these revisions, all string construction of labels for export to userspace (or elsewhere) is performed using the sbuf API, which prevents the consumer from having to perform laborious and intricate pointer and buffer checks. This substantially simplifies the externalization logic, both at the MAC Framework level, and in individual policies; this becomes especially useful when policies export more complex label data, such as with compartments in Biba and MLS. Bundled in here are some other minor fixes associated with externalization: including avoiding malloc while holding the process mutex in mac_lomac, and hence avoid a failure mode when printing labels during a downgrade operation due to the removal of the M_NOWAIT case. This has been running in the MAC development tree for about three weeks without problems. Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

Rename mac_create_cred() MAC Framework entry point to mac_copy_cred(), and the mpo_create_cred() MAC policy entry point to mpo_copy_cred_label(). This is more consistent with similar entry points for creation and label copying, as mac_create_cred() was called from crdup() as opposed to during process creation. For a number of policies, this removes the requirement for special handling when copying credential labels, and improves consistency.

typedef void (*mpo_mbuf_copy_label_t)(struct label *src,
Move MAC label storage for mbufs into m_tags from the m_pkthdr structure, returning some additional room in the first mbuf in a chain, and avoiding feature-specific contents in the mbuf header. To do this: - Modify mbuf_to_label() to extract the tag, returning NULL if not found. - Introduce mac_init_mbuf_tag() which does most of the work mac_init_mbuf() used to do, except on an m_tag rather than an mbuf. - Scale back mac_init_mbuf() to perform m_tag allocation and invoke mac_init_mbuf_tag(). - Replace mac_destroy_mbuf() with mac_destroy_mbuf_tag(), since m_tag's are now GC'd deep in the m_tag/mbuf code rather than at a higher level when mbufs are directly free()'d. - Add mac_copy_mbuf_tag() to support m_copy_pkthdr() and related notions. - Generally change all references to mbuf labels so that they use mbuf_to_label() rather than &mbuf->m_pkthdr.label. This required no changes in the MAC policies (yay!). - Tweak mbuf release routines to not call mac_destroy_mbuf(), tag destruction takes care of it for us now. - Remove MAC magic from m_copy_pkthdr() and m_move_pkthdr() -- the existing m_tag support does all this for us. Note that we can no longer just zero the m_tag list on the target mbuf, rather, we have to delete the chain because m_tag's will already be hung off freshly allocated mbuf's. - Tweak m_tag copying routines so that if we're copying a MAC m_tag, we don't do a binary copy, rather, we initialize the new storage and do a deep copy of the label. - Remove use of MAC_FLAG_INITIALIZED in a few bizarre places having to do with mbuf header copies previously. - When an mbuf is copied in ip_input(), we no longer need to explicitly copy the label because it will get handled by the m_tag code now. - No longer any weird handling of MAC labels in if_loop.c during header copies. - Add MPC_LOADTIME_FLAG_LABELMBUFS flag to Biba, MLS, mac_test. In mac_test, handle the label==NULL case, since it can be dynamically loaded. In order to improve performance with this change, introduce the notion of "lazy MAC label allocation" -- only allocate m_tag storage for MAC labels if we're running with a policy that uses MAC labels on mbufs. Policies declare this intent by setting the MPC_LOADTIME_FLAG_LABELMBUFS flag in their load-time flags field during declaration. Note: this opens up the possibility of post-boot policy modules getting back NULL slot entries even though they have policy invariants of non-NULL slot entries, as the policy might have been loaded after the mbuf was allocated, leaving the mbuf without label storage. Policies that cannot handle this case must be declared as NOTLATE, or must be modified. - mac_labelmbufs holds the current cumulative status as to whether any policies require mbuf labeling or not. This is updated whenever the active policy set changes by the function mac_policy_updateflags(). The function iterates the list and checks whether any have the flag set. Write access to this variable is protected by the policy list; read access is currently not protected for performance reasons. This might change if it causes problems. - Add MAC_POLICY_LIST_ASSERT_EXCLUSIVE() to permit the flags update function to assert appropriate locks. - This makes allocation in mac_init_mbuf() conditional on the flag.

Revised APIs for user process label management; the existing APIs relied on all label parsing occuring in userland, and knowledge of the loaded policies in the user libraries. This revision of the API pushes that parsing into the kernel, avoiding the need for shared library support of policies in userland, permitting statically linked binaries (such as ls, ps, and ifconfig) to use MAC labels. In these API revisions, high level parsing of the MAC label is done in the MAC Framework, and interpretation of label elements is delegated to the MAC policy modules. This permits modules to export zero or more label elements to user space if desired, and support them in the manner they want and with the semantics they want.

typedef int (*mpo_cred_internalize_label_t)(struct label *label,
Revised APIs for user process label management; the existing APIs relied on all label parsing occuring in userland, and knowledge of the loaded policies in the user libraries. This revision of the API pushes that parsing into the kernel, avoiding the need for shared library support of policies in userland, permitting statically linked binaries (such as ls, ps, and ifconfig) to use MAC labels. In these API revisions, high level parsing of the MAC label is done in the MAC Framework, and interpretation of label elements is delegated to the MAC policy modules. This permits modules to export zero or more label elements to user space if desired, and support them in the manner they want and with the semantics they want. This is believed to be the final revision of this interface: from the perspective of user applications, the API has actually not changed, although the ABI has.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

struct label *mplabel, struct devfs_dirent *de,
Slightly change the semantics of vnode labels for MAC: rather than "refreshing" the label on the vnode before use, just get the label right from inception. For single-label file systems, set the label in the generic VFS getnewvnode() code; for multi-label file systems, leave the labeling up to the file system. With UFS1/2, this means reading the extended attribute during vfs_vget() as the inode is pulled off disk, rather than hitting the extended attributes frequently during operations later, improving performance. This also corrects sematics for shared vnode locks, which were not previously present in the system. This chances the cache coherrency properties WRT out-of-band access to label data, but in an acceptable form. With UFS1, there is a small race condition during automatic extended attribute start -- this is not present with UFS2, and occurs because EAs aren't available at vnode inception. We'll introduce a work around for this shortly. Approved by: re Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

typedef void (*mpo_devfs_create_device_t)(struct ucred *cred,
When devfs cloning takes place, provide access to the credential of the process that caused the clone event to take place for the device driver creating the device. This allows cloned device drivers to adapt the device node based on security aspects of the process, such as the uid, gid, and MAC label. - Add a cred reference to struct cdev, so that when a device node is instantiated as a vnode, the cloning credential can be exposed to MAC. - Add make_dev_cred(), a version of make_dev() that additionally accepts the credential to stick in the struct cdev. Implement it and make_dev() in terms of a back-end make_dev_credv(). - Add a new event handler, dev_clone_cred, which can be registered to receive the credential instead of dev_clone, if desired. - Modify the MAC entry point mac_create_devfs_device() to accept an optional credential pointer (may be NULL), so that MAC policies can inspect and act on the label or other elements of the credential when initializing the skeleton device protections. - Modify tty_pty.c to register clone_dev_cred and invoke make_dev_cred(), so that the pty clone credential is exposed to the MAC Framework. While currently primarily focussed on MAC policies, this change is also a prerequisite for changes to allow ptys to be instantiated with the UID of the process looking up the pty. This requires further changes to the pty driver -- in particular, to immediately recycle pty nodes on last close so that the credential-related state can be recreated on next lookup.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

typedef void (*mpo_inpcb_create_t)(struct socket *so,
Introduce a MAC label reference in 'struct inpcb', which caches the MAC label referenced from 'struct socket' in the IPv4 and IPv6-based protocols. This permits MAC labels to be checked during network delivery operations without dereferencing inp->inp_socket to get to so->so_label, which will eventually avoid our having to grab the socket lock during delivery at the network layer. This change introduces 'struct inpcb' as a labeled object to the MAC Framework, along with the normal circus of entry points: initialization, creation from socket, destruction, as well as a delivery access control check. For most policies, the inpcb label will simply be a cache of the socket label, so a new protocol switch method is introduced, pr_sosetlabel() to notify protocols that the socket layer label has been updated so that the cache can be updated while holding appropriate locks. Most protocols implement this using pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use the the worker function in_pcbsosetlabel(), which calls into the MAC Framework to perform a cache update. Biba, LOMAC, and MLS implement these entry points, as do the stub policy, and test policy. Reviewed by: sam, bms Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

Switch TCP over to using the inpcb label when responding in timed wait, rather than the socket label. This avoids reaching up to the socket layer during connection close, which requires locking changes. To do this, introduce MAC Framework entry point mac_create_mbuf_from_inpcb(), which is called from tcp_twrespond() instead of calling mac_create_mbuf_from_socket() or mac_create_mbuf_netlayer(). Introduce MAC Policy entry point mpo_create_mbuf_from_inpcb(), and implementations for various policies, which generally just copy label data from the inpcb to the mbuf. Assert the inpcb lock in the entry point since we require consistency for the inpcb label reference. Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

typedef void (*mpo_inpcb_sosetlabel_t)(struct socket *so,
Introduce a MAC label reference in 'struct inpcb', which caches the MAC label referenced from 'struct socket' in the IPv4 and IPv6-based protocols. This permits MAC labels to be checked during network delivery operations without dereferencing inp->inp_socket to get to so->so_label, which will eventually avoid our having to grab the socket lock during delivery at the network layer. This change introduces 'struct inpcb' as a labeled object to the MAC Framework, along with the normal circus of entry points: initialization, creation from socket, destruction, as well as a delivery access control check. For most policies, the inpcb label will simply be a cache of the socket label, so a new protocol switch method is introduced, pr_sosetlabel() to notify protocols that the socket layer label has been updated so that the cache can be updated while holding appropriate locks. Most protocols implement this using pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use the the worker function in_pcbsosetlabel(), which calls into the MAC Framework to perform a cache update. Biba, LOMAC, and MLS implement these entry points, as do the stub policy, and test policy. Reviewed by: sam, bms Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

typedef void (*mpo_mbuf_create_from_firewall_t)(struct mbuf *m,
Introduce a new entry point, mac_create_mbuf_from_firewall. This entry point exists to allow the mandatory access control policy to properly initialize mbufs generated by the firewall. An example where this might happen is keep alive packets, or ICMP error packets in response to other packets. This takes care of kernel panics associated with un-initialize mbuf labels when the firewall generates packets. [1] I modified this patch from it's original version, the initial patch introduced a number of entry points which were programmatically equivalent. So I introduced only one. Instead, we should leverage mac_create_mbuf_netlayer() which is used for similar situations, an example being icmp_error() This will minimize the impact associated with the MFC Submitted by: mlaier [1] MFC after: 1 week This is a RELENG_6 candidate

struct label *label);
Fix LOR between the syncache and inpcb locks when MAC is present in the kernel. This LOR snuck in with some of the recent syncache changes. To fix this, the inpcb handling was changed: - Hang a MAC label off the syncache object - When the syncache entry is initially created, we pickup the PCB lock is held because we extract information from it while initializing the syncache entry. While we do this, copy the MAC label associated with the PCB and use it for the syncache entry. - When the packet is transmitted, copy the label from the syncache entry to the mbuf so it can be processed by security policies which analyze mbuf labels. This change required that the MAC framework be extended to support the label copy operations from the PCB to the syncache entry, and then from the syncache entry to the mbuf. These functions really should be referencing the syncache structure instead of the label. However, due to some of the complexities associated with exposing this syncache structure we operate directly on it's label pointer. This should be OK since we aren't making any access control decisions within this code directly, we are merely allocating and copying label storage so we can properly initialize mbuf labels for any packets the syncache code might create. This also has a nice side effect of caching. Prior to this change, the PCB would be looked up/locked for each packet transmitted. Now the label is cached at the time the syncache entry is initialized. Submitted by: andre [1] Discussed with: rwatson [1] andre submitted the tcp_syncache.c changes

struct vnode *vp, struct label *vplabel,
Bring in two sets of changes: (1) Permit userland applications to request a change of label atomic with an execve() via mac_execve(). This is required for the SEBSD port of SELinux/FLASK. Attempts to invoke this without MAC compiled in result in ENOSYS, as with all other MAC system calls. Complexity, if desired, is present in policy modules, rather than the framework. (2) Permit policies to have access to both the label of the vnode being executed as well as the interpreter if it's a shell script or related UNIX nonsense. Because we can't hold both vnode locks at the same time, cache the interpreter label. SEBSD relies on this because it supports secure transitioning via shell script executables. Other policies might want to take both labels into account during an integrity or confidentiality decision at execve()-time.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

typedef int (*mpo_inpcb_check_deliver_t)(struct inpcb *inp,
Introduce a MAC label reference in 'struct inpcb', which caches the MAC label referenced from 'struct socket' in the IPv4 and IPv6-based protocols. This permits MAC labels to be checked during network delivery operations without dereferencing inp->inp_socket to get to so->so_label, which will eventually avoid our having to grab the socket lock during delivery at the network layer. This change introduces 'struct inpcb' as a labeled object to the MAC Framework, along with the normal circus of entry points: initialization, creation from socket, destruction, as well as a delivery access control check. For most policies, the inpcb label will simply be a cache of the socket label, so a new protocol switch method is introduced, pr_sosetlabel() to notify protocols that the socket layer label has been updated so that the cache can be updated while holding appropriate locks. Most protocols implement this using pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use the the worker function in_pcbsosetlabel(), which calls into the MAC Framework to perform a cache update. Biba, LOMAC, and MLS implement these entry points, as do the stub policy, and test policy. Reviewed by: sam, bms Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

Merge first in a series of TrustedBSD MAC Framework KPI changes from Mac OS X Leopard--rationalize naming for entry points to the following general forms: mac_<object>_<method/action> mac_<object>_check_<method/action> The previous naming scheme was inconsistent and mostly reversed from the new scheme. Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names. All MAC policy modules will need to be recompiled, and modules not updates as part of this commit will need to be modified to conform to the new KPI.

Allow MAC policy modules to control access to audit configuration system calls. Add MAC Framework entry points and MAC policy entry points for audit(), auditctl(), auditon(), setaudit(), aud setauid(). MAC Framework entry points are only added for audit system calls where additional argument context may be useful for policy decision-making; other audit system calls without arguments may be controlled via the priv(9) entry points. Update various policy modules to implement audit-related checks, and in some cases, other missing system-related checks. Obtained from: TrustedBSD Project Sponsored by: SPARTA, Inc.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

Merge first in a series of TrustedBSD MAC Framework KPI changes from Mac OS X Leopard--rationalize naming for entry points to the following general forms: mac_<object>_<method/action> mac_<object>_check_<method/action> The previous naming scheme was inconsistent and mostly reversed from the new scheme. Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names. All MAC policy modules will need to be recompiled, and modules not updates as part of this commit will need to be modified to conform to the new KPI.

Merge first in a series of TrustedBSD MAC Framework KPI changes from Mac OS X Leopard--rationalize naming for entry points to the following general forms: mac_<object>_<method/action> mac_<object>_check_<method/action> The previous naming scheme was inconsistent and mostly reversed from the new scheme. Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names.

typedef int (*mpo_vnode_check_stat_t)(struct ucred *active_cred,
Pass active_cred and file_cred into the MAC framework explicitly for mac_check_vnode_{poll,read,stat,write}(). Pass in fp->f_cred when calling these checks with a struct file available. Otherwise, pass NOCRED. All currently MAC policies use active_cred, but could now offer the cached credential semantic used for the base system security model.

struct ucred *file_cred, struct vnode *vp,
Normalize variable naming in the MAC Framework by adopting the normal variable name conventions for arguments passed into the framework -- for example, name network interfaces 'ifp', sockets 'so', mounts 'mp', mbufs 'm', processes 'p', etc, wherever possible. Previously there was significant variation in this regard. Normalize copyright lists to ranges where sensible.

Fix LOR between the syncache and inpcb locks when MAC is present in the kernel. This LOR snuck in with some of the recent syncache changes. To fix this, the inpcb handling was changed: - Hang a MAC label off the syncache object - When the syncache entry is initially created, we pickup the PCB lock is held because we extract information from it while initializing the syncache entry. While we do this, copy the MAC label associated with the PCB and use it for the syncache entry. - When the packet is transmitted, copy the label from the syncache entry to the mbuf so it can be processed by security policies which analyze mbuf labels. This change required that the MAC framework be extended to support the label copy operations from the PCB to the syncache entry, and then from the syncache entry to the mbuf. These functions really should be referencing the syncache structure instead of the label. However, due to some of the complexities associated with exposing this syncache structure we operate directly on it's label pointer. This should be OK since we aren't making any access control decisions within this code directly, we are merely allocating and copying label storage so we can properly initialize mbuf labels for any packets the syncache code might create. This also has a nice side effect of caching. Prior to this change, the PCB would be looked up/locked for each packet transmitted. Now the label is cached at the time the syncache entry is initialized. Submitted by: andre [1] Discussed with: rwatson [1] andre submitted the tcp_syncache.c changes

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

Move MAC label storage for mbufs into m_tags from the m_pkthdr structure, returning some additional room in the first mbuf in a chain, and avoiding feature-specific contents in the mbuf header. To do this: - Modify mbuf_to_label() to extract the tag, returning NULL if not found. - Introduce mac_init_mbuf_tag() which does most of the work mac_init_mbuf() used to do, except on an m_tag rather than an mbuf. - Scale back mac_init_mbuf() to perform m_tag allocation and invoke mac_init_mbuf_tag(). - Replace mac_destroy_mbuf() with mac_destroy_mbuf_tag(), since m_tag's are now GC'd deep in the m_tag/mbuf code rather than at a higher level when mbufs are directly free()'d. - Add mac_copy_mbuf_tag() to support m_copy_pkthdr() and related notions. - Generally change all references to mbuf labels so that they use mbuf_to_label() rather than &mbuf->m_pkthdr.label. This required no changes in the MAC policies (yay!). - Tweak mbuf release routines to not call mac_destroy_mbuf(), tag destruction takes care of it for us now. - Remove MAC magic from m_copy_pkthdr() and m_move_pkthdr() -- the existing m_tag support does all this for us. Note that we can no longer just zero the m_tag list on the target mbuf, rather, we have to delete the chain because m_tag's will already be hung off freshly allocated mbuf's. - Tweak m_tag copying routines so that if we're copying a MAC m_tag, we don't do a binary copy, rather, we initialize the new storage and do a deep copy of the label. - Remove use of MAC_FLAG_INITIALIZED in a few bizarre places having to do with mbuf header copies previously. - When an mbuf is copied in ip_input(), we no longer need to explicitly copy the label because it will get handled by the m_tag code now. - No longer any weird handling of MAC labels in if_loop.c during header copies. - Add MPC_LOADTIME_FLAG_LABELMBUFS flag to Biba, MLS, mac_test. In mac_test, handle the label==NULL case, since it can be dynamically loaded. In order to improve performance with this change, introduce the notion of "lazy MAC label allocation" -- only allocate m_tag storage for MAC labels if we're running with a policy that uses MAC labels on mbufs. Policies declare this intent by setting the MPC_LOADTIME_FLAG_LABELMBUFS flag in their load-time flags field during declaration. Note: this opens up the possibility of post-boot policy modules getting back NULL slot entries even though they have policy invariants of non-NULL slot entries, as the policy might have been loaded after the mbuf was allocated, leaving the mbuf without label storage. Policies that cannot handle this case must be declared as NOTLATE, or must be modified. - mac_labelmbufs holds the current cumulative status as to whether any policies require mbuf labeling or not. This is updated whenever the active policy set changes by the function mac_policy_updateflags(). The function iterates the list and checks whether any have the flag set. Write access to this variable is protected by the policy list; read access is currently not protected for performance reasons. This might change if it causes problems. - Add MAC_POLICY_LIST_ASSERT_EXCLUSIVE() to permit the flags update function to assert appropriate locks. - This makes allocation in mac_init_mbuf() conditional on the flag.

Begin committing support for Mandatory Access Control and extensible kernel access control. The MAC framework permits loadable kernel modules to link to the kernel at compile-time, boot-time, or run-time, and augment the system security policy. This commit includes the initial kernel implementation, although the interface with the userland components of the oeprating system is still under work, and not all kernel subsystems are supported. Later in this commit sequence, documentation of which kernel subsystems will not work correctly with a kernel compiled with MAC support will be added. Include files to declare MAC userland interface (mac.h), MAC subsystem entry points (mac.h), and MAC policy entry points (mac_policy.h). These files define the interface between the kernel and the MAC framework, and between the MAC framework and each registered policy module. These APIs and ABIs may not be assumed to be stable until following FreeBSD 5.1-RELEASE. Obtained from: TrustedBSD Project Sponsored by: DARPA, NAI Labs

Move to C99 sparse structure initialization for the mac_policy_ops structure definition, rather than using an operation vector we translate into the structure. Originally, we used a vector for two reasons: (1) We wanted to define the structure sparsely, which wasn't supported by the C compiler for structures. For a policy with five entry points, you don't want to have to stick in a few hundred NULL function pointers. (2) We thought it would improve ABI compatibility allowing modules to work with kernels that had a superset of the entry points defined in the module, even if the kernel had changed its entry point set. Both of these no longer apply: (1) C99 gives us a way to sparsely define a static structure. (2) The ABI problems existed anyway, due to enumeration numbers, argument changes, and semantic mismatches. Since the going rule for FreeBSD is that you really need your modules to pretty closely match your kernel, it's not worth the complexity. This submit eliminates the operation vector, dynamic allocation of the operation structure, copying of the vector to the structure, and redoes the vectors in each policy to direct structure definitions. One enourmous benefit of this change is that we now get decent type checking on policy entry point implementation arguments.
