| Subject: [PATCH 2/2] Remove the attr.5 man page (moved to man-pages) |
| |
| Commit dce9b4448c7f2b22bd206cd068fb05cb2f3255b9 from |
| https://git.savannah.nongnu.org/git/attr.git |
| |
| The attr.5 page is part of the extended attribute system call documentation, |
| which has been moved into the man-pages package. Move the attr.5 page there |
| as well. |
| |
| Upstream-Status: Backport |
| |
| [MA: updated to apply directly to v2.4.47] |

| -.TH ATTR 5 |
| -.SH NAME |
| -attr - Extended attributes |
| -.SH DESCRIPTION |
| -Extended attributes are name:value pairs associated permanently with |
| -files and directories, similar to the environment strings associated |
| -with a process. |
| -An attribute may be defined or undefined. |
| -If it is defined, its value may be empty or non-empty. |
| -.PP |
| -Extended attributes are extensions to the normal attributes which are |
| -associated with all inodes in the system (i.e. the |
| -.BR stat (2) |
| -data). |
| -They are often used to provide additional functionality |
| -to a filesystem \- for example, additional security features such as |
| -Access Control Lists (ACLs) may be implemented using extended attributes. |
| -.PP |
| -Users with search access to a file or directory may retrieve a list of |
| -attribute names defined for that file or directory. |
| -.PP |
| -Extended attributes are accessed as atomic objects. |
| -Reading retrieves the whole value of an attribute and stores it in a buffer. |
| -Writing replaces any previous value with the new value. |
| -.PP |
| -Space consumed for extended attributes is counted towards the disk quotas |
| -of the file owner and file group. |
| -.PP |
| -Currently, support for extended attributes is implemented on Linux by the |
| -ext2, ext3, ext4, XFS, JFS and reiserfs filesystems. |
| -.SH EXTENDED ATTRIBUTE NAMESPACES |
| -Attribute names are zero-terminated strings. |
| -The attribute name is always specified in the fully qualified |
| -.IR namespace.attribute |
| -form, eg. |
| -.IR user.mime_type , |
| -.IR trusted.md5sum , |
| -.IR system.posix_acl_access , |
| -or |
| -.IR security.selinux . |
| -.PP |
| -The namespace mechanism is used to define different classes of extended |
| -attributes. |
| -These different classes exist for several reasons, e.g. the permissions |
| -and capabilities required for manipulating extended attributes of one |
| -namespace may differ to another. |
| -.PP |
| -Currently the |
| -.IR security , |
| -.IR system , |
| -.IR trusted , |
| -and |
| -.IR user |
| -extended attribute classes are defined as described below. Additional |
| -classes may be added in the future. |
| -.SS Extended security attributes |
| -The security attribute namespace is used by kernel security modules, |
| -such as Security Enhanced Linux. |
| -Read and write access permissions to security attributes depend on the |
| -policy implemented for each security attribute by the security module. |
| -When no security module is loaded, all processes have read access to |
| -extended security attributes, and write access is limited to processes |
| -that have the CAP_SYS_ADMIN capability. |
| -.SS Extended system attributes |
| -Extended system attributes are used by the kernel to store system |
| -objects such as Access Control Lists and Capabilities. Read and write |
| -access permissions to system attributes depend on the policy implemented |
| -for each system attribute implemented by filesystems in the kernel. |
| -.SS Trusted extended attributes |
| -Trusted extended attributes are visible and accessible only to processes that |
| -have the CAP_SYS_ADMIN capability (the super user usually has this |
| -capability). |
| -Attributes in this class are used to implement mechanisms in user |
| -space (i.e., outside the kernel) which keep information in extended attributes |
| -to which ordinary processes should not have access. |
| -.SS Extended user attributes |
| -Extended user attributes may be assigned to files and directories for |
| -storing arbitrary additional information such as the mime type, |
| -character set or encoding of a file. The access permissions for user |
| -attributes are defined by the file permission bits. |
| -.PP |
| -The file permission bits of regular files and directories are |
| -interpreted differently from the file permission bits of special files |
| -and symbolic links. For regular files and directories the file |
| -permission bits define access to the file's contents, while for device special |
| -files they define access to the device described by the special file. |
| -The file permissions of symbolic links are not used in access |
| -checks. These differences would allow users to consume filesystem resources in |
| -a way not controllable by disk quotas for group or world writable special files and directories. |
| -.PP |
| -For this reason, extended user attributes are only allowed for regular files and directories, and access to extended user attributes is restricted to the |
| -owner and to users with appropriate capabilities for directories with the |
| -sticky bit set (see the |
| -.BR chmod (1) |
| -manual page for an explanation of Sticky Directories). |
| -.SH FILESYSTEM DIFFERENCES |
| -The kernel and the filesystem may place limits on the maximum number |
| -and size of extended attributes that can be associated with a file. |
| -Some file systems, such as ext2/3 and reiserfs, require the filesystem |
| -to be mounted with the |
| -.B user_xattr |
| -mount option in order for extended user attributes to be used. |
| -.PP |
| -In the current ext2, ext3 and ext4 filesystem implementations, each |
| -extended attribute must fit on a single filesystem block (1024, 2048 |
| -or 4096 bytes, depending on the block size specified when the |
| -filesystem was created). |
| -.PP |
| -In the XFS and reiserfs filesystem implementations, there is no |
| -practical limit on the number or size of extended attributes |
| -associated with a file, and the algorithms used to store extended |
| -attribute information on disk are scalable. |
| -.PP |
| -In the JFS filesystem implementation, names can be up to 255 bytes and |
| -values up to 65,535 bytes. |
| -.SH ADDITIONAL NOTES |
| -Since the filesystems on which extended attributes are stored might also |
| -be used on architectures with a different byte order and machine word |
| -size, care should be taken to store attribute values in an architecture |
| -independent format. |
