| 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. |
Stephen Smalley | 5e41ff9 | 2005-09-09 13:01:35 -0700 | [diff] [blame] | 253 | * @inode_init_security: |
| 254 | * Obtain the security attribute name suffix and value to set on a newly |
| 255 | * created inode and set up the incore security field for the new inode. |
| 256 | * This hook is called by the fs code as part of the inode creation |
| 257 | * transaction and provides for atomic labeling of the inode, unlike |
| 258 | * the post_create/mkdir/... hooks called by the VFS. The hook function |
| 259 | * is expected to allocate the name and value via kmalloc, with the caller |
| 260 | * being responsible for calling kfree after using them. |
| 261 | * If the security module does not use security attributes or does |
| 262 | * not wish to put a security attribute on this particular inode, |
| 263 | * then it should return -EOPNOTSUPP to skip this processing. |
| 264 | * @inode contains the inode structure of the newly created inode. |
| 265 | * @dir contains the inode structure of the parent directory. |
| 266 | * @name will be set to the allocated name suffix (e.g. selinux). |
| 267 | * @value will be set to the allocated attribute value. |
| 268 | * @len will be set to the length of the value. |
| 269 | * Returns 0 if @name and @value have been successfully set, |
| 270 | * -EOPNOTSUPP if no security attribute is needed, or |
| 271 | * -ENOMEM on memory allocation failure. |

| 311 | * and not this hook. |
| 312 | * @dir contains the inode structure of parent of the new file. |
| 313 | * @dentry contains the dentry structure of the new file. |
| 314 | * @mode contains the mode of the new file. |
| 315 | * @dev contains the the device number. |
| 316 | * Return 0 if permission is granted. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 317 | * @inode_rename: |

| 331 | * @nd contains the nameidata structure for the parent directory. |
| 332 | * Return 0 if permission is granted. |
| 333 | * @inode_permission: |
| 334 | * Check permission before accessing an inode. This hook is called by the |
| 335 | * existing Linux permission function, so a security module can use it to |
| 336 | * provide additional checking for existing Linux permission checks. |
| 337 | * Notice that this hook is called when a file is opened (as well as many |
| 338 | * other operations), whereas the file_security_ops permission hook is |
| 339 | * called when the actual read/write operations are performed. |
| 340 | * @inode contains the inode structure to check. |
| 341 | * @mask contains the permission mask. |
| 342 | * @nd contains the nameidata (may be NULL). |
| 343 | * Return 0 if permission is granted. |
| 344 | * @inode_setattr: |
| 345 | * Check permission before setting file attributes. Note that the kernel |
| 346 | * call to notify_change is performed from several locations, whenever |
| 347 | * file attributes change (such as when a file is truncated, chown/chmod |
| 348 | * operations, transferring disk quotas, etc). |
| 349 | * @dentry contains the dentry structure for the file. |
| 350 | * @attr is the iattr structure containing the new file attributes. |

| 356 | * Return 0 if permission is granted. |
| 357 | * @inode_delete: |
| 358 | * @inode contains the inode structure for deleted inode. |
| 359 | * This hook is called when a deleted inode is released (i.e. an inode |
| 360 | * with no hard links has its use count drop to zero). A security module |
| 361 | * can use this hook to release any persistent label associated with the |
| 362 | * inode. |
| 363 | * @inode_setxattr: |
| 364 | * Check permission before setting the extended attributes |
| 365 | * @value identified by @name for @dentry. |
| 366 | * Return 0 if permission is granted. |
| 367 | * @inode_post_setxattr: |
| 368 | * Update inode security field after successful setxattr operation. |
| 369 | * @value identified by @name for @dentry. |

| 371 | * Check permission before obtaining the extended attributes |
| 372 | * identified by @name for @dentry. |
| 373 | * Return 0 if permission is granted. |
| 374 | * @inode_listxattr: |
| 375 | * Check permission before obtaining the list of extended attribute |
| 376 | * names for @dentry. |
| 377 | * Return 0 if permission is granted. |
| 378 | * @inode_removexattr: |
| 379 | * Check permission before removing the extended attribute |
| 380 | * identified by @name for @dentry. |
| 381 | * Return 0 if permission is granted. |
| 382 | * @inode_getsecurity: |
| 383 | * Copy the extended attribute representation of the security label |
| 384 | * associated with @name for @inode into @buffer. @buffer may be |
| 385 | * NULL to request the size of the buffer required. @size indicates |
| 386 | * the size of @buffer in bytes. Note that @name is the remainder |
| 387 | * of the attribute name after the security. prefix has been removed. |
| 388 | * Return number of bytes used/required on success. |

| 403 | * Security hooks for file operations |
| 404 | * |
| 405 | * @file_permission: |
| 406 | * Check file permissions before accessing an open file. This hook is |
| 407 | * called by various operations that read or write files. A security |
| 408 | * module can use this hook to perform additional checking on these |
| 409 | * operations, e.g. to revalidate permissions on use to support privilege |
| 410 | * bracketing or policy changes. Notice that this hook is used when the |
| 411 | * actual read/write operations are performed, whereas the |
| 412 | * inode_security_ops hook is called when a file is opened (as well as |
| 413 | * many other operations). |
| 414 | * Caveat: Although this hook can be used to revalidate permissions for |
| 415 | * various system call operations that read or write files, it does not |
| 416 | * address the revalidation of permissions for memory-mapped files. |
| 417 | * Security modules must handle this separately if they need such |
| 418 | * revalidation. |

| 435 | * Check permission for an ioctl operation on @file. Note that @arg can |
| 436 | * sometimes represents a user space pointer; in other cases, it may be a |
| 437 | * simple integer value. When @arg represents a user space pointer, it |
| 438 | * should never be used by the security module. |
| 439 | * Return 0 if permission is granted. |
| 440 | * @file_mmap : |
| 441 | * Check permissions for a mmap operation. The @file may be NULL, e.g. |

| 461 | * @file_fcntl: |
| 462 | * Check permission before allowing the file operation specified by @cmd |
| 463 | * from being performed on the file @file. Note that @arg can sometimes |
| 464 | * represents a user space pointer; in other cases, it may be a simple |
| 465 | * integer value. When @arg represents a user space pointer, it should |

| 478 | * process @tsk. Note that this hook is sometimes called from interrupt. |
| 479 | * Note that the fown_struct, @fown, is never outside the context of a |
| 480 | * struct file, so the file structure (and associated security information) |
| 481 | * can always be obtained: |
| 482 | * (struct file *)((long)fown - offsetof(struct file,f_owner)); |
| 483 | * @tsk contains the structure of task receiving signal. |
| 484 | * @fown contains the file owner information. |

| 486 | * Return 0 if permission is granted. |
| 487 | * @file_receive: |
| 488 | * This hook allows security modules to control the ability of a process |
| 489 | * to receive an open file descriptor via socket IPC. |

| 657 | * The @unix_stream_connect and @unix_may_send hooks were necessary because |
| 658 | * Linux provides an alternative to the conventional file name space for Unix |
| 659 | * domain sockets. Whereas binding and connecting to sockets in the file name |
| 660 | * space is mediated by the typical file permissions (and caught by the mknod |
| 661 | * and permission hooks in inode_security_ops), binding and connecting to |
| 662 | * sockets in the abstract name space is completely unmediated. Sufficient |
| 663 | * control of Unix domain sockets in the abstract name space isn't possible |
| 664 | * using only the socket layer hooks, since we need to know the actual target |
| 665 | * socket, which is not looked up until we are inside the af_unix code. |

| 681 | * allocate and and attach security information to |
| 682 | * sock->inode->i_security. This hook may be used to update the |

| 767 | * from Netfilter's IP input hooks since it is the first time that the |
| 768 | * incoming sk_buff @skb has been associated with a particular socket, @sk. |
| 769 | * @sk contains the sock (not socket) associated with the incoming sk_buff. |
| 770 | * @skb contains the incoming network data. |

| 902 | * created. |
| 903 | * @sma contains the semaphore structure. |
| 904 | * @semflg contains the operation control flags. |
| 905 | * Return 0 if permission is granted. |

| 911 | * @cmd contains the operation to be performed. |
| 912 | * Return 0 if permission is granted. |
| 913 | * @sem_semop |
| 914 | * Check permissions before performing operations on members of the |
| 915 | * semaphore set @sma. If the @alter flag is nonzero, the semaphore set |
| 916 | * may be modified. |
| 917 | * @sma contains the semaphore structure. |
| 918 | * @sops contains the operations to perform. |
| 919 | * @nsops contains the number of operations to perform. |
| 920 | * @alter contains the flag indicating whether changes are to be made. |
| 921 | * Return 0 if permission is granted. |
| 922 | * |
| 923 | * @ptrace: |
| 924 | * Check permission before allowing the @parent process to trace the |
| 925 | * @child process. |
| 926 | * Security modules may also want to perform a process tracing check |
| 927 | * during an execve in the set_security or apply_creds hooks of |
| 928 | * binprm_security_ops if the process is being traced and its security |
| 929 | * attributes would be changed by the execve. |
| 930 | * @parent contains the task_struct structure for parent process. |
| 931 | * @child contains the task_struct structure for child process. |
| 932 | * Return 0 if permission is granted. |
| 933 | * @capget: |
| 934 | * Get the @effective, @inheritable, and @permitted capability sets for |
| 935 | * the @target process. The hook may also perform permission checking to |

| 937 | * of the @target process. |
| 938 | * @target contains the task_struct structure for target process. |
| 939 | * @effective contains the effective capability set. |

| 943 | * @capset_check: |
| 944 | * Check permission before setting the @effective, @inheritable, and |
| 945 | * @permitted capability sets for the @target process. |
| 946 | * Caveat: @target is also set to current if a set of processes is |
| 947 | * specified (i.e. all processes other than current and init or a |
| 948 | * particular process group). Hence, the capset_set hook may need to |
| 949 | * revalidate permission to the actual target process. |
| 950 | * @target contains the task_struct structure for target process. |
| 951 | * @effective contains the effective capability set. |
| 952 | * @inheritable contains the inheritable capability set. |
| 953 | * @permitted contains the permitted capability set. |

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