94 | * struct security_operations - main security structure | |
95 | * | |
96 | * Security hooks for program execution operations. | |
97 | * | |
98 | * @bprm_alloc_security: | |
99 | * Allocate and attach a security structure to the @bprm->security field. | |
100 | * The security field is initialized to NULL when the bprm structure is | |
101 | * allocated. | |
102 | * @bprm contains the linux_binprm structure to be modified. | |
103 | * Return 0 if operation was successful. | |
104 | * @bprm_free_security: | |
105 | * @bprm contains the linux_binprm structure to be modified. | |
106 | * Deallocate and clear the @bprm->security field. | |
107 | * @bprm_apply_creds: | |
108 | * Compute and set the security attributes of a process being transformed | |
109 | * by an execve operation based on the old attributes (current->security) | |
110 | * and the information saved in @bprm->security by the set_security hook. | |
111 | * Since this hook function (and its caller) are void, this hook can not | |
112 | * return an error. However, it can leave the security attributes of the | |
113 | * process unchanged if an access failure occurs at this point. | |
114 | * bprm_apply_creds is called under task_lock. @unsafe indicates various | |
115 | * reasons why it may be unsafe to change security state. | |
116 | * @bprm contains the linux_binprm structure. | |
117 | * @bprm_post_apply_creds: | |
118 | * Runs after bprm_apply_creds with the task_lock dropped, so that | |
119 | * functions which cannot be called safely under the task_lock can | |
120 | * be used. This hook is a good place to perform state changes on | |
121 | * the process such as closing open file descriptors to which access | |
122 | * is no longer granted if the attributes were changed. | |
123 | * Note that a security module might need to save state between | |
124 | * bprm_apply_creds and bprm_post_apply_creds to store the decision | |
125 | * on whether the process may proceed. | |
126 | * @bprm contains the linux_binprm structure. | |
127 | * @bprm_set_security: | |
128 | * Save security information in the bprm->security field, typically based | |
129 | * on information about the bprm->file, for later use by the apply_creds | |
130 | * hook. This hook may also optionally check permissions (e.g. for | |
131 | * transitions between security domains). | |
132 | * This hook may be called multiple times during a single execve, e.g. for | |
133 | * interpreters. The hook can tell whether it has already been called by | |
134 | * checking to see if @bprm->security is non-NULL. If so, then the hook | |
135 | * may decide either to retain the security information saved earlier or | |
136 | * to replace it. | |
137 | * @bprm contains the linux_binprm structure. | |
138 | * Return 0 if the hook is successful and permission is granted. | |
139 | * @bprm_check_security: | |
140 | * This hook mediates the point when a search for a binary handler will | |
141 | * begin. It allows a check the @bprm->security value which is set in | |
142 | * the preceding set_security call. The primary difference from | |
143 | * set_security is that the argv list and envp list are reliably | |
144 | * available in @bprm. This hook may be called multiple times | |
145 | * during a single execve; and in each pass set_security is called | |
146 | * first. | |
147 | * @bprm contains the linux_binprm structure. | |
148 | * Return 0 if the hook is successful and permission is granted. | |
149 | * @bprm_secureexec: | |
150 | * Return a boolean value (0 or 1) indicating whether a "secure exec" | |
151 | * is required. The flag is passed in the auxiliary table | |
152 | * on the initial stack to the ELF interpreter to indicate whether libc | |
153 | * should enable secure mode. | |
154 | * @bprm contains the linux_binprm structure. | |
155 | * | |
156 | * Security hooks for filesystem operations. | |
157 | * | |
158 | * @sb_alloc_security: | |
159 | * Allocate and attach a security structure to the sb->s_security field. | |
160 | * The s_security field is initialized to NULL when the structure is | |
161 | * allocated. | |
162 | * @sb contains the super_block structure to be modified. | |
163 | * Return 0 if operation was successful. | |
164 | * @sb_free_security: | |
165 | * Deallocate and clear the sb->s_security field. | |
166 | * @sb contains the super_block structure to be modified. | |
167 | * @sb_statfs: | |
168 | * Check permission before obtaining filesystem statistics for the @sb | |
169 | * filesystem. | |
170 | * @sb contains the super_block structure for the filesystem. | |
171 | * Return 0 if permission is granted. | |
172 | * @sb_mount: | |
173 | * Check permission before an object specified by @dev_name is mounted on | |
174 | * the mount point named by @nd. For an ordinary mount, @dev_name | |
175 | * identifies a device if the file system type requires a device. For a | |
176 | * remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a | |
177 | * loopback/bind mount (@flags & MS_BIND), @dev_name identifies the | |
178 | * pathname of the object being mounted. | |
179 | * @dev_name contains the name for object being mounted. | |
180 | * @nd contains the nameidata structure for mount point object. | |
181 | * @type contains the filesystem type. | |
182 | * @flags contains the mount flags. | |
183 | * @data contains the filesystem-specific data. | |
184 | * Return 0 if permission is granted. | |
185 | * @sb_copy_data: | |
186 | * Allow mount option data to be copied prior to parsing by the filesystem, | |
187 | * so that the security module can extract security-specific mount | |
188 | * options cleanly (a filesystem may modify the data e.g. with strsep()). | |
189 | * This also allows the original mount data to be stripped of security- | |
190 | * specific options to avoid having to make filesystems aware of them. | |
191 | * @type the type of filesystem being mounted. | |
192 | * @orig the original mount data copied from userspace. | |
193 | * @copy copied data which will be passed to the security module. | |
194 | * Returns 0 if the copy was successful. | |
195 | * @sb_check_sb: | |
196 | * Check permission before the device with superblock @mnt->sb is mounted | |
197 | * on the mount point named by @nd. | |
198 | * @mnt contains the vfsmount for device being mounted. | |
199 | * @nd contains the nameidata object for the mount point. | |
200 | * Return 0 if permission is granted. | |
201 | * @sb_umount: | |
202 | * Check permission before the @mnt file system is unmounted. | |
203 | * @mnt contains the mounted file system. | |
204 | * @flags contains the unmount flags, e.g. MNT_FORCE. | |
205 | * Return 0 if permission is granted. | |
206 | * @sb_umount_close: | |
207 | * Close any files in the @mnt mounted filesystem that are held open by | |
208 | * the security module. This hook is called during an umount operation | |
209 | * prior to checking whether the filesystem is still busy. | |
210 | * @mnt contains the mounted filesystem. | |
211 | * @sb_umount_busy: | |
212 | * Handle a failed umount of the @mnt mounted filesystem, e.g. re-opening | |
213 | * any files that were closed by umount_close. This hook is called during | |
214 | * an umount operation if the umount fails after a call to the | |
215 | * umount_close hook. | |
216 | * @mnt contains the mounted filesystem. | |
217 | * @sb_post_remount: | |
218 | * Update the security module's state when a filesystem is remounted. | |
219 | * This hook is only called if the remount was successful. | |
220 | * @mnt contains the mounted file system. | |
221 | * @flags contains the new filesystem flags. | |
222 | * @data contains the filesystem-specific data. | |
223 | * @sb_post_mountroot: | |
224 | * Update the security module's state when the root filesystem is mounted. | |
225 | * This hook is only called if the mount was successful. | |
226 | * @sb_post_addmount: | |
227 | * Update the security module's state when a filesystem is mounted. | |
228 | * This hook is called any time a mount is successfully grafetd to | |
229 | * the tree. | |
230 | * @mnt contains the mounted filesystem. | |
231 | * @mountpoint_nd contains the nameidata structure for the mount point. | |
232 | * @sb_pivotroot: | |
233 | * Check permission before pivoting the root filesystem. | |
234 | * @old_nd contains the nameidata structure for the new location of the current root (put_old). | |
235 | * @new_nd contains the nameidata structure for the new root (new_root). | |
236 | * Return 0 if permission is granted. | |
237 | * @sb_post_pivotroot: | |
238 | * Update module state after a successful pivot. | |
239 | * @old_nd contains the nameidata structure for the old root. | |
240 | * @new_nd contains the nameidata structure for the new root. | |
241 | * | |
242 | * Security hooks for inode operations. | |
243 | * | |
244 | * @inode_alloc_security: | |
245 | * Allocate and attach a security structure to @inode->i_security. The | |
246 | * i_security field is initialized to NULL when the inode structure is | |
247 | * allocated. | |
248 | * @inode contains the inode structure. | |
249 | * Return 0 if operation was successful. | |
250 | * @inode_free_security: | |
251 | * @inode contains the inode structure. | |
252 | * Deallocate the inode security structure and set @inode->i_security to | |
253 | * NULL. | |
5e41ff9e SS |
254 | * @inode_init_security: |
255 | * Obtain the security attribute name suffix and value to set on a newly | |
256 | * created inode and set up the incore security field for the new inode. | |
257 | * This hook is called by the fs code as part of the inode creation | |
258 | * transaction and provides for atomic labeling of the inode, unlike | |
259 | * the post_create/mkdir/... hooks called by the VFS. The hook function | |
260 | * is expected to allocate the name and value via kmalloc, with the caller | |
261 | * being responsible for calling kfree after using them. | |
262 | * If the security module does not use security attributes or does | |
263 | * not wish to put a security attribute on this particular inode, | |
264 | * then it should return -EOPNOTSUPP to skip this processing. | |
265 | * @inode contains the inode structure of the newly created inode. | |
266 | * @dir contains the inode structure of the parent directory. | |
267 | * @name will be set to the allocated name suffix (e.g. selinux). | |
268 | * @value will be set to the allocated attribute value. | |
269 | * @len will be set to the length of the value. | |
270 | * Returns 0 if @name and @value have been successfully set, | |
271 | * -EOPNOTSUPP if no security attribute is needed, or | |
272 | * -ENOMEM on memory allocation failure. | |

289 | * Return 0 if permission is granted. | |
290 | * @inode_symlink: | |
291 | * Check the permission to create a symbolic link to a file. | |
292 | * @dir contains the inode structure of parent directory of the symbolic link. | |
293 | * @dentry contains the dentry structure of the symbolic link. | |
294 | * @old_name contains the pathname of file. | |
295 | * Return 0 if permission is granted. | |
1da177e4 LT |
296 | * @inode_mkdir: |

298 | * associated with inode strcture @dir. | |
299 | * @dir containst the inode structure of parent of the directory to be created. | |
300 | * @dentry contains the dentry structure of new directory. | |
301 | * @mode contains the mode of new directory. | |
302 | * Return 0 if permission is granted. | |

306 | * @dentry contains the dentry structure of directory to be removed. | |
307 | * Return 0 if permission is granted. | |
308 | * @inode_mknod: | |
309 | * Check permissions when creating a special file (or a socket or a fifo | |
310 | * file created via the mknod system call). Note that if mknod operation | |
311 | * is being done for a regular file, then the create hook will be called | |
312 | * and not this hook. | |
313 | * @dir contains the inode structure of parent of the new file. | |
314 | * @dentry contains the dentry structure of the new file. | |
315 | * @mode contains the mode of the new file. | |

334 | * @inode_permission: | |
335 | * Check permission before accessing an inode. This hook is called by the | |
336 | * existing Linux permission function, so a security module can use it to | |
337 | * provide additional checking for existing Linux permission checks. | |
338 | * Notice that this hook is called when a file is opened (as well as many | |
339 | * other operations), whereas the file_security_ops permission hook is | |

349 | * operations, transferring disk quotas, etc). | |
350 | * @dentry contains the dentry structure for the file. | |
351 | * @attr is the iattr structure containing the new file attributes. | |

354 | * Check permission before obtaining file attributes. | |
355 | * @mnt is the vfsmount where the dentry was looked up | |
356 | * @dentry contains the dentry structure for the file. | |
357 | * Return 0 if permission is granted. | |
358 | * @inode_delete: | |
359 | * @inode contains the inode structure for deleted inode. | |
360 | * This hook is called when a deleted inode is released (i.e. an inode | |
361 | * with no hard links has its use count drop to zero). A security module | |
362 | * can use this hook to release any persistent label associated with the | |
363 | * inode. | |
364 | * @inode_setxattr: | |
365 | * Check permission before setting the extended attributes | |
366 | * @value identified by @name for @dentry. | |
367 | * Return 0 if permission is granted. | |

372 | * Check permission before obtaining the extended attributes | |
373 | * identified by @name for @dentry. | |
374 | * Return 0 if permission is granted. | |
375 | * @inode_listxattr: | |
376 | * Check permission before obtaining the list of extended attribute | |
377 | * names for @dentry. | |
378 | * Return 0 if permission is granted. | |
379 | * @inode_removexattr: | |
380 | * Check permission before removing the extended attribute | |
381 | * identified by @name for @dentry. | |
382 | * Return 0 if permission is granted. | |
383 | * @inode_getsecurity: | |
384 | * Copy the extended attribute representation of the security label | |
385 | * associated with @name for @inode into @buffer. @buffer may be | |
386 | * NULL to request the size of the buffer required. @size indicates | |
387 | * the size of @buffer in bytes. Note that @name is the remainder | |
388 | * of the attribute name after the security. prefix has been removed. | |
d381d8a9 JM |
389 | * @err is the return value from the preceding fs getxattr call, |
390 | * and can be used by the security module to determine whether it | |
391 | * should try and canonicalize the attribute value. | |
1da177e4 LT |
392 | * Return number of bytes used/required on success. |
393 | * @inode_setsecurity: | |
394 | * Set the security label associated with @name for @inode from the | |
395 | * extended attribute value @value. @size indicates the size of the | |
396 | * @value in bytes. @flags may be XATTR_CREATE, XATTR_REPLACE, or 0. | |
397 | * Note that @name is the remainder of the attribute name after the | |
398 | * security. prefix has been removed. | |
399 | * Return 0 on success. | |
400 | * @inode_listsecurity: | |
401 | * Copy the extended attribute names for the security labels | |
402 | * associated with @inode into @buffer. The maximum size of @buffer | |

407 | * Security hooks for file operations | |
408 | * | |
409 | * @file_permission: | |
410 | * Check file permissions before accessing an open file. This hook is | |
411 | * called by various operations that read or write files. A security | |
412 | * module can use this hook to perform additional checking on these | |
413 | * operations, e.g. to revalidate permissions on use to support privilege | |
414 | * bracketing or policy changes. Notice that this hook is used when the | |
415 | * actual read/write operations are performed, whereas the | |
416 | * inode_security_ops hook is called when a file is opened (as well as | |
417 | * many other operations). | |
418 | * Caveat: Although this hook can be used to revalidate permissions for | |
419 | * various system call operations that read or write files, it does not | |
420 | * address the revalidation of permissions for memory-mapped files. | |
421 | * Security modules must handle this separately if they need such | |
422 | * revalidation. | |
423 | * @file contains the file structure being accessed. | |

439 | * Check permission for an ioctl operation on @file. Note that @arg can | |
440 | * sometimes represents a user space pointer; in other cases, it may be a | |
441 | * simple integer value. When @arg represents a user space pointer, it | |
442 | * should never be used by the security module. | |
443 | * Return 0 if permission is granted. | |
444 | * @file_mmap : | |
445 | * Check permissions for a mmap operation. The @file may be NULL, e.g. | |

465 | * @file_fcntl: | |
466 | * Check permission before allowing the file operation specified by @cmd | |
467 | * from being performed on the file @file. Note that @arg can sometimes | |
468 | * represents a user space pointer; in other cases, it may be a simple | |
469 | * integer value. When @arg represents a user space pointer, it should | |
470 | * never be used by the security module. | |

480 | * @file_send_sigiotask: | |
481 | * Check permission for the file owner @fown to send SIGIO or SIGURG to the | |
482 | * process @tsk. Note that this hook is sometimes called from interrupt. | |
483 | * Note that the fown_struct, @fown, is never outside the context of a | |
484 | * struct file, so the file structure (and associated security information) | |
485 | * can always be obtained: | |
486 | * (struct file *)((long)fown - offsetof(struct file,f_owner)); | |
487 | * @tsk contains the structure of task receiving signal. | |
488 | * @fown contains the file owner information. | |

490 | * Return 0 if permission is granted. | |
491 | * @file_receive: | |
492 | * This hook allows security modules to control the ability of a process | |
493 | * to receive an open file descriptor via socket IPC. | |

661 | * The @unix_stream_connect and @unix_may_send hooks were necessary because | |
662 | * Linux provides an alternative to the conventional file name space for Unix | |
663 | * domain sockets. Whereas binding and connecting to sockets in the file name | |
664 | * space is mediated by the typical file permissions (and caught by the mknod | |
665 | * and permission hooks in inode_security_ops), binding and connecting to | |
666 | * sockets in the abstract name space is completely unmediated. Sufficient | |
667 | * control of Unix domain sockets in the abstract name space isn't possible | |
668 | * using only the socket layer hooks, since we need to know the actual target | |
669 | * socket, which is not looked up until we are inside the af_unix code. | |

685 | * allocate and and attach security information to | |
686 | * sock->inode->i_security. This hook may be used to update the | |

771 | * from Netfilter's IP input hooks since it is the first time that the | |
772 | * incoming sk_buff @skb has been associated with a particular socket, @sk. | |
773 | * @sk contains the sock (not socket) associated with the incoming sk_buff. | |
774 | * @skb contains the incoming network data. | |

920 | * @sem_free_security: | |
921 | * deallocate security struct for this semaphore | |
922 | * @sma contains the semaphore structure. | |
923 | * @sem_associate: | |
924 | * Check permission when a semaphore is requested through the semget | |
925 | * system call. This hook is only called when returning the semaphore | |

927 | * created. | |
928 | * @sma contains the semaphore structure. | |
929 | * @semflg contains the operation control flags. | |
930 | * Return 0 if permission is granted. | |
931 | * @sem_semctl: | |

936 | * @cmd contains the operation to be performed. | |
937 | * Return 0 if permission is granted. | |
938 | * @sem_semop | |
939 | * Check permissions before performing operations on members of the | |
940 | * semaphore set @sma. If the @alter flag is nonzero, the semaphore set | |
941 | * may be modified. | |
942 | * @sma contains the semaphore structure. | |
943 | * @sops contains the operations to perform. | |
944 | * @nsops contains the number of operations to perform. | |
945 | * @alter contains the flag indicating whether changes are to be made. | |
946 | * Return 0 if permission is granted. | |
947 | * | |
948 | * @ptrace: | |
949 | * Check permission before allowing the @parent process to trace the | |
950 | * @child process. | |
951 | * Security modules may also want to perform a process tracing check | |
952 | * during an execve in the set_security or apply_creds hooks of | |
953 | * binprm_security_ops if the process is being traced and its security | |
954 | * attributes would be changed by the execve. | |
955 | * @parent contains the task_struct structure for parent process. | |
956 | * @child contains the task_struct structure for child process. | |
957 | * Return 0 if permission is granted. | |
958 | * @capget: | |
959 | * Get the @effective, @inheritable, and @permitted capability sets for | |
960 | * the @target process. The hook may also perform permission checking to | |

962 | * of the @target process. | |
963 | * @target contains the task_struct structure for target process. | |
964 | * @effective contains the effective capability set. | |
965 | * @inheritable contains the inheritable capability set. | |
966 | * @permitted contains the permitted capability set. | |
967 | * Return 0 if the capability sets were successfully obtained. | |
968 | * @capset_check: | |
969 | * Check permission before setting the @effective, @inheritable, and | |
970 | * @permitted capability sets for the @target process. | |
971 | * Caveat: @target is also set to current if a set of processes is | |
972 | * specified (i.e. all processes other than current and init or a | |
973 | * particular process group). Hence, the capset_set hook may need to | |
974 | * revalidate permission to the actual target process. | |
975 | * @target contains the task_struct structure for target process. | |
976 | * @effective contains the effective capability set. | |
977 | * @inheritable contains the inheritable capability set. | |
978 | * @permitted contains the permitted capability set. | |
979 | * Return 0 if permission is granted. | |
980 | * @capset_set: | |
981 | * Set the @effective, @inheritable, and @permitted capability sets for | |
982 | * the @target process. Since capset_check cannot always check permission | |
983 | * to the real @target process, this hook may also perform permission | |
984 | * checking to determine if the current process is allowed to set the | |
985 | * capability sets of the @target process. However, this hook has no way | |
986 | * of returning an error due to the structure of the sys_capset code. | |
987 | * @target contains the task_struct structure for target process. | |
988 | * @effective contains the effective capability set. | |
989 | * @inheritable contains the inheritable capability set. | |
990 | * @permitted contains the permitted capability set. | |
991 | * @acct: | |
992 | * Check permission before enabling or disabling process accounting. If | |
993 | * accounting is being enabled, then @file refers to the open file used to | |
994 | * store accounting records. If accounting is being disabled, then @file | |
995 | * is NULL. | |
996 | * @file contains the file structure for the accounting file (may be NULL). | |
997 | * Return 0 if permission is granted. | |
998 | * @sysctl: | |
999 | * Check permission before accessing the @table sysctl variable in the | |
1000 | * manner specified by @op. | |
1001 | * @table contains the ctl_table structure for the sysctl variable. | |
1002 | * @op contains the operation (001 = search, 002 = write, 004 = read). | |
1003 | * Return 0 if permission is granted. | |
1004 | * @capable: | |
1005 | * Check whether the @tsk process has the @cap capability. | |
1006 | * @tsk contains the task_struct for the process. | |
1007 | * @cap contains the capability <include/linux/capability.h>. | |
1008 | * Return 0 if the capability is granted for @tsk. | |
1009 | * @syslog: | |
1010 | * Check permission before accessing the kernel message ring or changing | |
1011 | * logging to the console. | |
1012 | * See the syslog(2) manual page for an explanation of the @type values. | |
1013 | * @type contains the type of action. | |
1014 | * Return 0 if permission is granted. | |
1015 | * @settime: | |
1016 | * Check permission to change the system time. | |
1017 | * struct timespec and timezone are defined in include/linux/time.h | |
1018 | * @ts contains new time | |
1019 | * @tz contains new timezone | |
1020 | * Return 0 if permission is granted. | |
1021 | * @vm_enough_memory: | |
1022 | * Check permissions for allocating a new virtual mapping. | |
1023 | * @pages contains the number of pages. | |
1024 | * Return 0 if permission is granted. | |
1025 | * | |
1026 | * @register_security: | |
1027 | * allow module stacking. | |
1028 | * @name contains the name of the security module being stacked. | |
1029 | * @ops contains a pointer to the struct security_operations of the module to stack. | |
1030 | * @unregister_security: | |
1031 | * remove a stacked module. | |
1032 | * @name contains the name of the security module being unstacked. | |
1033 | * @ops contains a pointer to the struct security_operations of the module to unstack. | |
1034 | * | |
1035 | * This is the main security structure. | |
