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!

+/**
+ * struct security_operations - main security structure
+ *
+ * Security hooks for program execution operations.
+ *
+ * @bprm_alloc_security:
+ * Allocate and attach a security structure to the @bprm->security field.
+ * The security field is initialized to NULL when the bprm structure is
+ * allocated.
+ * @bprm contains the linux_binprm structure to be modified.
+ * Return 0 if operation was successful.
+ * @bprm_free_security:
+ * @bprm contains the linux_binprm structure to be modified.
+ * Deallocate and clear the @bprm->security field.
+ * @bprm_apply_creds:
+ * Compute and set the security attributes of a process being transformed
+ * by an execve operation based on the old attributes (current->security)
+ * and the information saved in @bprm->security by the set_security hook.
+ * Since this hook function (and its caller) are void, this hook can not
+ * return an error. However, it can leave the security attributes of the
+ * process unchanged if an access failure occurs at this point.
+ * bprm_apply_creds is called under task_lock. @unsafe indicates various
+ * reasons why it may be unsafe to change security state.
+ * @bprm contains the linux_binprm structure.
+ * @bprm_post_apply_creds:
+ * Runs after bprm_apply_creds with the task_lock dropped, so that
+ * functions which cannot be called safely under the task_lock can
+ * be used. This hook is a good place to perform state changes on
+ * the process such as closing open file descriptors to which access
+ * is no longer granted if the attributes were changed.
+ * Note that a security module might need to save state between
+ * bprm_apply_creds and bprm_post_apply_creds to store the decision
+ * on whether the process may proceed.
+ * @bprm contains the linux_binprm structure.
+ * @bprm_set_security:
+ * Save security information in the bprm->security field, typically based
+ * on information about the bprm->file, for later use by the apply_creds
+ * hook. This hook may also optionally check permissions (e.g. for
+ * transitions between security domains).
+ * This hook may be called multiple times during a single execve, e.g. for
+ * interpreters. The hook can tell whether it has already been called by
+ * checking to see if @bprm->security is non-NULL. If so, then the hook
+ * may decide either to retain the security information saved earlier or
+ * to replace it.
+ * @bprm contains the linux_binprm structure.
+ * Return 0 if the hook is successful and permission is granted.
+ * @bprm_check_security:
+ * This hook mediates the point when a search for a binary handler will
+ * begin. It allows a check the @bprm->security value which is set in
+ * the preceding set_security call. The primary difference from
+ * set_security is that the argv list and envp list are reliably
+ * available in @bprm. This hook may be called multiple times
+ * during a single execve; and in each pass set_security is called
+ * first.
+ * @bprm contains the linux_binprm structure.
+ * Return 0 if the hook is successful and permission is granted.
+ * @bprm_secureexec:
+ * Return a boolean value (0 or 1) indicating whether a "secure exec"
+ * is required. The flag is passed in the auxiliary table
+ * on the initial stack to the ELF interpreter to indicate whether libc
+ * should enable secure mode.
+ * @bprm contains the linux_binprm structure.
+ *
+ * Security hooks for filesystem operations.
+ *
+ * @sb_alloc_security:
+ * Allocate and attach a security structure to the sb->s_security field.
+ * The s_security field is initialized to NULL when the structure is
+ * allocated.
+ * @sb contains the super_block structure to be modified.
+ * Return 0 if operation was successful.
+ * @sb_free_security:
+ * Deallocate and clear the sb->s_security field.
+ * @sb contains the super_block structure to be modified.
+ * @sb_statfs:
+ * Check permission before obtaining filesystem statistics for the @sb
+ * filesystem.
+ * @sb contains the super_block structure for the filesystem.
+ * Return 0 if permission is granted.
+ * @sb_mount:
+ * Check permission before an object specified by @dev_name is mounted on
+ * the mount point named by @nd. For an ordinary mount, @dev_name
+ * identifies a device if the file system type requires a device. For a
+ * remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a
+ * loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
+ * pathname of the object being mounted.
+ * @dev_name contains the name for object being mounted.
+ * @nd contains the nameidata structure for mount point object.
+ * @type contains the filesystem type.
+ * @flags contains the mount flags.
+ * @data contains the filesystem-specific data.
+ * Return 0 if permission is granted.
+ * @sb_copy_data:
+ * Allow mount option data to be copied prior to parsing by the filesystem,
+ * so that the security module can extract security-specific mount
+ * options cleanly (a filesystem may modify the data e.g. with strsep()).
+ * This also allows the original mount data to be stripped of security-
+ * specific options to avoid having to make filesystems aware of them.
+ * @type the type of filesystem being mounted.
+ * @orig the original mount data copied from userspace.
+ * @copy copied data which will be passed to the security module.
+ * Returns 0 if the copy was successful.
+ * @sb_check_sb:
+ * Check permission before the device with superblock @mnt->sb is mounted
+ * on the mount point named by @nd.
+ * @mnt contains the vfsmount for device being mounted.
+ * @nd contains the nameidata object for the mount point.
+ * Return 0 if permission is granted.
+ * @sb_umount:
+ * Check permission before the @mnt file system is unmounted.
+ * @mnt contains the mounted file system.
+ * @flags contains the unmount flags, e.g. MNT_FORCE.
+ * Return 0 if permission is granted.
+ * @sb_umount_close:
+ * Close any files in the @mnt mounted filesystem that are held open by
+ * the security module. This hook is called during an umount operation
+ * prior to checking whether the filesystem is still busy.
+ * @mnt contains the mounted filesystem.
+ * @sb_umount_busy:
+ * Handle a failed umount of the @mnt mounted filesystem, e.g. re-opening
+ * any files that were closed by umount_close. This hook is called during
+ * an umount operation if the umount fails after a call to the
+ * umount_close hook.
+ * @mnt contains the mounted filesystem.
+ * @sb_post_remount:
+ * Update the security module's state when a filesystem is remounted.
+ * This hook is only called if the remount was successful.
+ * @mnt contains the mounted file system.
+ * @flags contains the new filesystem flags.
+ * @data contains the filesystem-specific data.
+ * @sb_post_mountroot:
+ * Update the security module's state when the root filesystem is mounted.
+ * This hook is only called if the mount was successful.
+ * @sb_post_addmount:
+ * Update the security module's state when a filesystem is mounted.
+ * This hook is called any time a mount is successfully grafetd to
+ * the tree.
+ * @mnt contains the mounted filesystem.
+ * @mountpoint_nd contains the nameidata structure for the mount point.
+ * @sb_pivotroot:
+ * Check permission before pivoting the root filesystem.
+ * @old_nd contains the nameidata structure for the new location of the current root (put_old).
+ * @new_nd contains the nameidata structure for the new root (new_root).
+ * Return 0 if permission is granted.
+ * @sb_post_pivotroot:
+ * Update module state after a successful pivot.
+ * @old_nd contains the nameidata structure for the old root.
+ * @new_nd contains the nameidata structure for the new root.
+ *
+ * Security hooks for inode operations.
+ *
+ * @inode_alloc_security:
+ * Allocate and attach a security structure to @inode->i_security. The
+ * i_security field is initialized to NULL when the inode structure is
+ * allocated.
+ * @inode contains the inode structure.
+ * Return 0 if operation was successful.
+ * @inode_free_security:

+ * @dentry contains the dentry structure of new symbolic link.
+ * @old_name contains the pathname of file.

+ * @nd contains the nameidata structure for the parent directory.
+ * Return 0 if permission is granted.
+ * @inode_permission:
+ * Check permission before accessing an inode. This hook is called by the
+ * existing Linux permission function, so a security module can use it to
+ * provide additional checking for existing Linux permission checks.
+ * Notice that this hook is called when a file is opened (as well as many
+ * other operations), whereas the file_security_ops permission hook is

+ * @mask contains the permission mask.
+ * @nd contains the nameidata (may be NULL).
+ * Return 0 if permission is granted.

+ * Return 0 if permission is granted.
+ * @inode_delete:

+ * with no hard links has its use count drop to zero). A security module
+ * can use this hook to release any persistent label associated with the

+ * of the attribute name after the security. prefix has been removed.
+ * Return number of bytes used/required on success.
+ * @inode_setsecurity:

+ * security. prefix has been removed.
+ * Return 0 on success.
+ * @inode_listsecurity:
+ * Copy the extended attribute names for the security labels
+ * associated with @inode into @buffer. The maximum size of @buffer
+ * is specified by @buffer_size. @buffer may be NULL to request
+ * the size of the buffer required.
+ * Returns number of bytes used/required on success.
+ *
+ * Security hooks for file operations
+ *
+ * @file_permission:
+ * Check file permissions before accessing an open file. This hook is
+ * called by various operations that read or write files. A security
+ * module can use this hook to perform additional checking on these
+ * operations, e.g. to revalidate permissions on use to support privilege
+ * bracketing or policy changes. Notice that this hook is used when the
+ * actual read/write operations are performed, whereas the
+ * inode_security_ops hook is called when a file is opened (as well as
+ * many other operations).
+ * Caveat: Although this hook can be used to revalidate permissions for
+ * various system call operations that read or write files, it does not
+ * address the revalidation of permissions for memory-mapped files.
+ * Security modules must handle this separately if they need such
+ * revalidation.
+ * @file contains the file structure being accessed.
+ * @mask contains the requested permissions.
+ * Return 0 if permission is granted.
+ * @file_alloc_security:
+ * Allocate and attach a security structure to the file->f_security field.
+ * The security field is initialized to NULL when the structure is first
+ * created.
+ * @file contains the file structure to secure.
+ * Return 0 if the hook is successful and permission is granted.
+ * @file_free_security:

+ * @file_ioctl:
+ * @file contains the file structure.
+ * @cmd contains the operation to perform.
+ * @arg contains the operational arguments.
+ * Check permission for an ioctl operation on @file. Note that @arg can
+ * sometimes represents a user space pointer; in other cases, it may be a
+ * simple integer value. When @arg represents a user space pointer, it
+ * should never be used by the security module.
+ * Return 0 if permission is granted.
+ * @file_mmap :
+ * Check permissions for a mmap operation. The @file may be NULL, e.g.
+ * if mapping anonymous memory.
+ * @file contains the file structure for file to map (may be NULL).
+ * @reqprot contains the protection requested by the application.
+ * @prot contains the protection that will be applied by the kernel.
+ * @flags contains the operational flags.
+ * Return 0 if permission is granted.
+ * @file_mprotect:
+ * Check permissions before changing memory access permissions.
+ * @vma contains the memory region to modify.
+ * @reqprot contains the protection requested by the application.
+ * @prot contains the protection that will be applied by the kernel.
+ * Return 0 if permission is granted.
+ * @file_lock:
+ * Check permission before performing file locking operations.
+ * Note: this hook mediates both flock and fcntl style locks.
+ * @file contains the file structure.
+ * @cmd contains the posix-translated lock operation to perform
+ * (e.g. F_RDLCK, F_WRLCK).
+ * Return 0 if permission is granted.
+ * @file_fcntl:
+ * Check permission before allowing the file operation specified by @cmd
+ * from being performed on the file @file. Note that @arg can sometimes
+ * represents a user space pointer; in other cases, it may be a simple
+ * integer value. When @arg represents a user space pointer, it should
+ * never be used by the security module.
+ * @file contains the file structure.
+ * @cmd contains the operation to be performed.
+ * @arg contains the operational arguments.
+ * Return 0 if permission is granted.
+ * @file_set_fowner:
+ * Save owner security information (typically from current->security) in
+ * file->f_security for later use by the send_sigiotask hook.
+ * @file contains the file structure to update.
+ * Return 0 on success.
+ * @file_send_sigiotask:
+ * Check permission for the file owner @fown to send SIGIO or SIGURG to the
+ * process @tsk. Note that this hook is sometimes called from interrupt.
+ * Note that the fown_struct, @fown, is never outside the context of a
+ * struct file, so the file structure (and associated security information)
+ * can always be obtained:
+ * (struct file *)((long)fown - offsetof(struct file,f_owner));
+ * @tsk contains the structure of task receiving signal.
+ * @fown contains the file owner information.
+ * @sig is the signal that will be sent. When 0, kernel sends SIGIO.
+ * Return 0 if permission is granted.
+ * @file_receive:
+ * This hook allows security modules to control the ability of a process
+ * to receive an open file descriptor via socket IPC.
+ * @file contains the file structure being received.
+ * Return 0 if permission is granted.
+ *
+ * Security hooks for task operations.
+ *

+ * @clone_flags contains the flags indicating what should be shared.
+ * Return 0 if permission is granted.
+ * @task_alloc_security:
+ * @p contains the task_struct for child process.
+ * Allocate and attach a security structure to the p->security field. The
+ * security field is initialized to NULL when the task structure is
+ * allocated.
+ * Return 0 if operation was successful.
+ * @task_free_security:
+ * @p contains the task_struct for process.
+ * Deallocate and clear the p->security field.
+ * @task_setuid:
+ * Check permission before setting one or more of the user identity
+ * attributes of the current process. The @flags parameter indicates
+ * which of the set*uid system calls invoked this hook and how to
+ * interpret the @id0, @id1, and @id2 parameters. See the LSM_SETID
+ * definitions at the beginning of this file for the @flags values and
+ * their meanings.
+ * @id0 contains a uid.
+ * @id1 contains a uid.
+ * @id2 contains a uid.
+ * @flags contains one of the LSM_SETID_* values.
+ * Return 0 if permission is granted.
+ * @task_post_setuid:
+ * Update the module's state after setting one or more of the user
+ * identity attributes of the current process. The @flags parameter
+ * indicates which of the set*uid system calls invoked this hook. If
+ * @flags is LSM_SETID_FS, then @old_ruid is the old fs uid and the other
+ * parameters are not used.
+ * @old_ruid contains the old real uid (or fs uid if LSM_SETID_FS).
+ * @old_euid contains the old effective uid (or -1 if LSM_SETID_FS).

+ * interpret the @id0, @id1, and @id2 parameters. See the LSM_SETID
+ * definitions at the beginning of this file for the @flags values and
+ * their meanings.
+ * @id0 contains a gid.
