docs-rst: create an user's manual book
Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters
on an user's manual book.
As we'll be numbering the user's manual, remove the manual
numbering from SecurityBugs.

Before - asking for a device number make sure you actually need one. - - To have a major number allocated, or a minor number in situations - where that applies (e.g. busmice), please submit a patch and send to - the authors as indicated above. - - Keep the description of the device *in the same format - as this list*. The reason for this is that it is the only way we have - found to ensure we have all the requisite information to publish your - device and avoid conflicts. - - Finally, sometimes we have to play "namespace police." Please don't be - offended. We often get submissions for ``/dev`` names that would be bound - to cause conflicts down the road. We are trying to avoid getting in a - situation where we would have to suffer an incompatible forward - change.

Virtual consoles are named ``/dev/tty#``, with numbering -starting at ``/dev/tty1``; ``/dev/tty0`` is the current virtual console. -``/dev/tty0`` is the device that should be used to access the system video -card on those architectures for which the frame buffer devices -(``/dev/fb*``) are not applicable. Do not use ``/dev/console`` -for this purpose. - -The console device, ``/dev/console``, is the device to which system -messages should be sent, and on which logins should be permitted in -single-user mode. Starting with Linux 2.1.71, ``/dev/console`` is managed -by the kernel; for previous versions it should be a symbolic link to -either ``/dev/tty0``, a specific virtual console such as ``/dev/tty1``, or to -a serial port primary (``tty*``, not ``cu*``) device, depending on the -configuration of the system. - -Serial ports -++++++++++++ - -Serial ports are RS-232 serial ports and any device which simulates -one, either in hardware (such as internal modems) or in software (such -as the ISDN driver.) Under Linux, each serial ports has two device -names, the primary or callin device and the alternate or callout one. -Each kind of device is indicated by a different letter. For any -letter X, the names of the devices are ``/dev/ttyX#`` and ``/dev/cux#``, -respectively; for historical reasons, ``/dev/ttyS#`` and ``/dev/ttyC#`` -correspond to ``/dev/cua#`` and ``/dev/cub#``. In the future, it should be -expected that multiple letters will be used; all letters will be upper -case for the "tty" device (e.g. ``/dev/ttyDP#``) and lower case for the -"cu" device (e.g. ``/dev/cudp#``). - -The names ``/dev/ttyQ#`` and ``/dev/cuq#`` are reserved for local use. - -The alternate devices provide for kernel-based exclusion and somewhat -different defaults than the primary devices. Their main purpose is to -allow the use of serial ports with programs with no inherent or broken -support for serial ports. Their use is deprecated, and they may be -removed from a future version of Linux. - -Arbitration of serial ports is provided by the use of lock files with -the names ``/var/lock/LCK..ttyX#``. The contents of the lock file should -be the PID of the locking process as an ASCII number. - -It is common practice to install links such as /dev/modem -which point to serial ports. In order to ensure proper locking in the -presence of these links, it is recommended that software chase -symlinks and lock all possible names; additionally, it is recommended -that a lock file be installed with the corresponding alternate -device. In order to avoid deadlocks, it is recommended that the locks -are acquired in the following order, and released in the reverse: - - 1. The symbolic link name, if any (``/var/lock/LCK..modem``) - 2. The "tty" name (``/var/lock/LCK..ttyS2``) - 3. The alternate device name (``/var/lock/LCK..cua2``) - -In the case of nested symbolic links, the lock files should be -installed in the order the symlinks are resolved. - -Under no circumstances should an application hold a lock while waiting -for another to be released. In addition, applications which attempt -to create lock files for the corresponding alternate device names -should take into account the possibility of being used on a non-serial -port TTY, for which no alternate device would exist. - -Pseudoterminals (PTYs) -++++++++++++++++++++++ - -Pseudoterminals, or PTYs, are used to create login sessions or provide -other capabilities requiring a TTY line discipline (including SLIP or -PPP capability) to arbitrary data-generation processes. Each PTY has -a master side, named ``/dev/pty[p-za-e][0-9a-f]``, and a slave side, named -``/dev/tty[p-za-e][0-9a-f]``. The kernel arbitrates the use of PTYs by -allowing each master side to be opened only once. - -Once the master side has been opened, the corresponding slave device -can be used in the same manner as any TTY device. The master and -slave devices are connected by the kernel, generating the equivalent -of a bidirectional pipe with TTY capabilities. - -Recent versions of the Linux kernels and GNU libc contain support for -the System V/Unix98 naming scheme for PTYs, which assigns a common -device, ``/dev/ptmx``, to all the masters (opening it will automatically -give you a previously unassigned PTY) and a subdirectory, ``/dev/pts``, -for the slaves; the slaves are named with decimal integers (``/dev/pts/#`` -in our notation). This removes the problem of exhausting the -namespace and enables the kernel to automatically create the device -nodes for the slaves on demand using the "devpts" filesystem. - |
