Linux-2.6.12-rc2v2.6.12-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!

92/**
93 * struct security_operations - main security structure
94 *
95 * Security hooks for program execution operations.
96 *
97 * @bprm_alloc_security:
98 * Allocate and attach a security structure to the @bprm->security field.
99 * The security field is initialized to NULL when the bprm structure is
100 * allocated.
101 * @bprm contains the linux_binprm structure to be modified.
102 * Return 0 if operation was successful.
103 * @bprm_free_security:
104 * @bprm contains the linux_binprm structure to be modified.
105 * Deallocate and clear the @bprm->security field.
106 * @bprm_apply_creds:
107 * Compute and set the security attributes of a process being transformed
108 * by an execve operation based on the old attributes (current->security)
109 * and the information saved in @bprm->security by the set_security hook.
110 * Since this hook function (and its caller) are void, this hook can not
111 * return an error. However, it can leave the security attributes of the
112 * process unchanged if an access failure occurs at this point.
113 * bprm_apply_creds is called under task_lock. @unsafe indicates various
114 * reasons why it may be unsafe to change security state.
115 * @bprm contains the linux_binprm structure.
116 * @bprm_post_apply_creds:
117 * Runs after bprm_apply_creds with the task_lock dropped, so that
118 * functions which cannot be called safely under the task_lock can
119 * be used. This hook is a good place to perform state changes on
120 * the process such as closing open file descriptors to which access
121 * is no longer granted if the attributes were changed.
122 * Note that a security module might need to save state between
123 * bprm_apply_creds and bprm_post_apply_creds to store the decision
124 * on whether the process may proceed.
125 * @bprm contains the linux_binprm structure.
126 * @bprm_set_security:
127 * Save security information in the bprm->security field, typically based
128 * on information about the bprm->file, for later use by the apply_creds
129 * hook. This hook may also optionally check permissions (e.g. for
130 * transitions between security domains).
131 * This hook may be called multiple times during a single execve, e.g. for
132 * interpreters. The hook can tell whether it has already been called by
133 * checking to see if @bprm->security is non-NULL. If so, then the hook
134 * may decide either to retain the security information saved earlier or
135 * to replace it.
136 * @bprm contains the linux_binprm structure.
137 * Return 0 if the hook is successful and permission is granted.
138 * @bprm_check_security:
139 * This hook mediates the point when a search for a binary handler will
140 * begin. It allows a check the @bprm->security value which is set in
141 * the preceding set_security call. The primary difference from
142 * set_security is that the argv list and envp list are reliably
143 * available in @bprm. This hook may be called multiple times
144 * during a single execve; and in each pass set_security is called
145 * first.
146 * @bprm contains the linux_binprm structure.
147 * Return 0 if the hook is successful and permission is granted.
148 * @bprm_secureexec:
149 * Return a boolean value (0 or 1) indicating whether a "secure exec"
150 * is required. The flag is passed in the auxiliary table
151 * on the initial stack to the ELF interpreter to indicate whether libc
152 * should enable secure mode.
153 * @bprm contains the linux_binprm structure.
154 *
155 * Security hooks for filesystem operations.
156 *
157 * @sb_alloc_security:
158 * Allocate and attach a security structure to the sb->s_security field.
159 * The s_security field is initialized to NULL when the structure is
160 * allocated.
161 * @sb contains the super_block structure to be modified.
162 * Return 0 if operation was successful.
163 * @sb_free_security:
164 * Deallocate and clear the sb->s_security field.
165 * @sb contains the super_block structure to be modified.
166 * @sb_statfs:
167 * Check permission before obtaining filesystem statistics for the @sb
168 * filesystem.
169 * @sb contains the super_block structure for the filesystem.
170 * Return 0 if permission is granted.
171 * @sb_mount:
172 * Check permission before an object specified by @dev_name is mounted on
173 * the mount point named by @nd. For an ordinary mount, @dev_name
174 * identifies a device if the file system type requires a device. For a
175 * remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a
176 * loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
177 * pathname of the object being mounted.
178 * @dev_name contains the name for object being mounted.
179 * @nd contains the nameidata structure for mount point object.
180 * @type contains the filesystem type.
181 * @flags contains the mount flags.
182 * @data contains the filesystem-specific data.
183 * Return 0 if permission is granted.
184 * @sb_copy_data:
185 * Allow mount option data to be copied prior to parsing by the filesystem,
186 * so that the security module can extract security-specific mount
187 * options cleanly (a filesystem may modify the data e.g. with strsep()).
188 * This also allows the original mount data to be stripped of security-
189 * specific options to avoid having to make filesystems aware of them.
190 * @type the type of filesystem being mounted.
191 * @orig the original mount data copied from userspace.
192 * @copy copied data which will be passed to the security module.
193 * Returns 0 if the copy was successful.
194 * @sb_check_sb:
195 * Check permission before the device with superblock @mnt->sb is mounted
196 * on the mount point named by @nd.
197 * @mnt contains the vfsmount for device being mounted.
198 * @nd contains the nameidata object for the mount point.
199 * Return 0 if permission is granted.
200 * @sb_umount:
201 * Check permission before the @mnt file system is unmounted.
202 * @mnt contains the mounted file system.
203 * @flags contains the unmount flags, e.g. MNT_FORCE.
204 * Return 0 if permission is granted.
205 * @sb_umount_close:
206 * Close any files in the @mnt mounted filesystem that are held open by
207 * the security module. This hook is called during an umount operation
208 * prior to checking whether the filesystem is still busy.
209 * @mnt contains the mounted filesystem.
210 * @sb_umount_busy:
211 * Handle a failed umount of the @mnt mounted filesystem, e.g. re-opening
212 * any files that were closed by umount_close. This hook is called during
213 * an umount operation if the umount fails after a call to the
214 * umount_close hook.
215 * @mnt contains the mounted filesystem.
216 * @sb_post_remount:
217 * Update the security module's state when a filesystem is remounted.
218 * This hook is only called if the remount was successful.
219 * @mnt contains the mounted file system.
220 * @flags contains the new filesystem flags.
221 * @data contains the filesystem-specific data.
222 * @sb_post_mountroot:
223 * Update the security module's state when the root filesystem is mounted.
224 * This hook is only called if the mount was successful.
225 * @sb_post_addmount:
226 * Update the security module's state when a filesystem is mounted.
227 * This hook is called any time a mount is successfully grafetd to
228 * the tree.
229 * @mnt contains the mounted filesystem.
230 * @mountpoint_nd contains the nameidata structure for the mount point.
231 * @sb_pivotroot:
232 * Check permission before pivoting the root filesystem.
233 * @old_nd contains the nameidata structure for the new location of the current root (put_old).
234 * @new_nd contains the nameidata structure for the new root (new_root).
235 * Return 0 if permission is granted.
236 * @sb_post_pivotroot:
237 * Update module state after a successful pivot.
238 * @old_nd contains the nameidata structure for the old root.
239 * @new_nd contains the nameidata structure for the new root.
240 *
241 * Security hooks for inode operations.
242 *
243 * @inode_alloc_security:
244 * Allocate and attach a security structure to @inode->i_security. The
245 * i_security field is initialized to NULL when the inode structure is
246 * allocated.
247 * @inode contains the inode structure.
248 * Return 0 if operation was successful.
249 * @inode_free_security:
250 * @inode contains the inode structure.
251 * Deallocate the inode security structure and set @inode->i_security to
252 * NULL.
253 * @inode_create:
254 * Check permission to create a regular file.
255 * @dir contains inode structure of the parent of the new file.
256 * @dentry contains the dentry structure for the file to be created.
257 * @mode contains the file mode of the file to be created.
258 * Return 0 if permission is granted.
259 * @inode_post_create:
260 * Set the security attributes on a newly created regular file. This hook
261 * is called after a file has been successfully created.
262 * @dir contains the inode structure of the parent directory of the new file.

289 * @dentry contains the dentry structure of new symbolic link.
290 * @old_name contains the pathname of file.
291 * Set security attributes for a newly created symbolic link. Note that

310 * Return 0 if permission is granted.
311 * @inode_mknod:
312 * Check permissions when creating a special file (or a socket or a fifo
313 * file created via the mknod system call). Note that if mknod operation
314 * is being done for a regular file, then the create hook will be called
315 * and not this hook.

317 * @dentry contains the dentry structure of the new file.
318 * @mode contains the mode of the new file.

349 * Return 0 if permission is granted.
350 * @inode_permission:

353 * provide additional checking for existing Linux permission checks.
354 * Notice that this hook is called when a file is opened (as well as many
355 * other operations), whereas the file_security_ops permission hook is
356 * called when the actual read/write operations are performed.

372 * @dentry contains the dentry structure for the file.
373 * Return 0 if permission is granted.
374 * @inode_delete:
375 * @inode contains the inode structure for deleted inode.
376 * This hook is called when a deleted inode is released (i.e. an inode
377 * with no hard links has its use count drop to zero). A security module
378 * can use this hook to release any persistent label associated with the
379 * inode.
380 * @inode_setxattr:

382 * @value identified by @name for @dentry.
383 * Return 0 if permission is granted.
384 * @inode_post_setxattr:
385 * Update inode security field after successful setxattr operation.
386 * @value identified by @name for @dentry.
387 * @inode_getxattr:

393 * names for @dentry.
394 * Return 0 if permission is granted.
395 * @inode_removexattr:
396 * Check permission before removing the extended attribute
397 * identified by @name for @dentry.
398 * Return 0 if permission is granted.
399 * @inode_getsecurity:
400 * Copy the extended attribute representation of the security label
401 * associated with @name for @inode into @buffer. @buffer may be
402 * NULL to request the size of the buffer required. @size indicates
403 * the size of @buffer in bytes. Note that @name is the remainder
404 * of the attribute name after the security. prefix has been removed.
405 * Return number of bytes used/required on success.
406 * @inode_setsecurity:
407 * Set the security label associated with @name for @inode from the
408 * extended attribute value @value. @size indicates the size of the
409 * @value in bytes. @flags may be XATTR_CREATE, XATTR_REPLACE, or 0.
410 * Note that @name is the remainder of the attribute name after the
411 * security. prefix has been removed.
412 * Return 0 on success.
413 * @inode_listsecurity:
414 * Copy the extended attribute names for the security labels
415 * associated with @inode into @buffer. The maximum size of @buffer
416 * is specified by @buffer_size. @buffer may be NULL to request
417 * the size of the buffer required.
418 * Returns number of bytes used/required on success.
419 *
420 * Security hooks for file operations
421 *
422 * @file_permission:
423 * Check file permissions before accessing an open file. This hook is
424 * called by various operations that read or write files. A security
425 * module can use this hook to perform additional checking on these
426 * operations, e.g. to revalidate permissions on use to support privilege
427 * bracketing or policy changes. Notice that this hook is used when the
428 * actual read/write operations are performed, whereas the
429 * inode_security_ops hook is called when a file is opened (as well as
430 * many other operations).
431 * Caveat: Although this hook can be used to revalidate permissions for
432 * various system call operations that read or write files, it does not
433 * address the revalidation of permissions for memory-mapped files.
434 * Security modules must handle this separately if they need such
435 * revalidation.
436 * @file contains the file structure being accessed.
437 * @mask contains the requested permissions.
438 * Return 0 if permission is granted.
439 * @file_alloc_security:
440 * Allocate and attach a security structure to the file->f_security field.
441 * The security field is initialized to NULL when the structure is first
442 * created.
443 * @file contains the file structure to secure.
444 * Return 0 if the hook is successful and permission is granted.
445 * @file_free_security:
446 * Deallocate and free any security structures stored in file->f_security.
447 * @file contains the file structure being modified.
448 * @file_ioctl:
449 * @file contains the file structure.
450 * @cmd contains the operation to perform.

951 * Get the @effective, @inheritable, and @permitted capability sets for
952 * the @target process. The hook may also perform permission checking to
953 * determine if the current process is allowed to see the capability sets
954 * of the @target process.
955 * @target contains the task_struct structure for target process.
956 * @effective contains the effective capability set.
957 * @inheritable contains the inheritable capability set.
958 * @permitted contains the permitted capability set.
959 * Return 0 if the capability sets were successfully obtained.
960 * @capset_check:
961 * Check permission before setting the @effective, @inheritable, and
962 * @permitted capability sets for the @target process.
963 * Caveat: @target is also set to current if a set of processes is
964 * specified (i.e. all processes other than current and init or a
965 * particular process group). Hence, the capset_set hook may need to
966 * revalidate permission to the actual target process.
967 * @target contains the task_struct structure for target process.
968 * @effective contains the effective capability set.
969 * @inheritable contains the inheritable capability set.
970 * @permitted contains the permitted capability set.
971 * Return 0 if permission is granted.
972 * @capset_set:
973 * Set the @effective, @inheritable, and @permitted capability sets for
974 * the @target process. Since capset_check cannot always check permission
975 * to the real @target process, this hook may also perform permission
976 * checking to determine if the current process is allowed to set the
977 * capability sets of the @target process. However, this hook has no way
978 * of returning an error due to the structure of the sys_capset code.
979 * @target contains the task_struct structure for target process.
980 * @effective contains the effective capability set.
981 * @inheritable contains the inheritable capability set.
982 * @permitted contains the permitted capability set.
983 * @acct:
984 * Check permission before enabling or disabling process accounting. If
985 * accounting is being enabled, then @file refers to the open file used to
986 * store accounting records. If accounting is being disabled, then @file
987 * is NULL.
988 * @file contains the file structure for the accounting file (may be NULL).
989 * Return 0 if permission is granted.
990 * @sysctl:
991 * Check permission before accessing the @table sysctl variable in the
992 * manner specified by @op.
993 * @table contains the ctl_table structure for the sysctl variable.
994 * @op contains the operation (001 = search, 002 = write, 004 = read).
995 * Return 0 if permission is granted.
996 * @capable:
997 * Check whether the @tsk process has the @cap capability.
998 * @tsk contains the task_struct for the process.
999 * @cap contains the capability <include/linux/capability.h>.
1000 * Return 0 if the capability is granted for @tsk.
1001 * @syslog:
1002 * Check permission before accessing the kernel message ring or changing
1003 * logging to the console.
1004 * See the syslog(2) manual page for an explanation of the @type values.
1005 * @type contains the type of action.
1006 * Return 0 if permission is granted.
1007 * @settime:
1008 * Check permission to change the system time.
1009 * struct timespec and timezone are defined in include/linux/time.h
1010 * @ts contains new time
1011 * @tz contains new timezone
1012 * Return 0 if permission is granted.
1013 * @vm_enough_memory:
1014 * Check permissions for allocating a new virtual mapping.
1015 * @pages contains the number of pages.
1016 * Return 0 if permission is granted.
1017 *
1018 * @register_security:
1019 * allow module stacking.
1020 * @name contains the name of the security module being stacked.
1021 * @ops contains a pointer to the struct security_operations of the module to stack.
1022 * @unregister_security:
1023 * remove a stacked module.
1024 * @name contains the name of the security module being unstacked.
1025 * @ops contains a pointer to the struct security_operations of the module to unstack.
1026 *
1027 * This is the main security structure.
