Pull signal handling cleanups from Al Viro: "sigaltstack infrastructure + conversion for x86, alpha and um, COMPAT_SYSCALL_DEFINE infrastructure. Note that there are several conflicts between "unify SS_ONSTACK/SS_DISABLE definitions" and UAPI patches in mainline; resolution is trivial - just remove definitions of SS_ONSTACK and SS_DISABLED from arch/*/uapi/asm/signal.h; they are all identical and include/uapi/linux/signal.h contains the unified variant." Fixed up conflicts as per Al. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: alpha: switch to generic sigaltstack new helpers: __save_altstack/__compat_save_altstack, switch x86 and um to those generic compat_sys_sigaltstack() introduce generic sys_sigaltstack(), switch x86 and um to it new helper: compat_user_stack_pointer() new helper: restore_altstack() unify SS_ONSTACK/SS_DISABLE definitions new helper: current_user_stack_pointer() missing user_stack_pointer() instances Bury the conditionals from kernel_thread/kernel_execve series COMPAT_SYSCALL_DEFINE: infrastructure

config VT

bool "Virtual terminal"
|
|
---help---
|
|
If you say Y here, you will get support for terminal devices with
|
|
display and keyboard devices. These are called "virtual" because you
|
|
can run several virtual terminals (also called virtual consoles) on
|
|
one physical terminal. This is rather useful, for example one
|
|
virtual terminal can collect system messages and warnings, another
|
|
one can be used for a text-mode user session, and a third could run
|
|
an X session, all in parallel. Switching between virtual terminals
|
|
is done with certain key combinations, usually Alt-<function key>.
|
|
|
|
The setterm command ("man setterm") can be used to change the
|
|
properties (such as colors or beeping) of a virtual terminal. The
|
|
man page console_codes(4) ("man console_codes") contains the special
|
|
character sequences that can be used to change those properties
|
|
directly. The fonts used on virtual terminals can be changed with
|
|
the setfont ("man setfont") command and the key bindings are defined
|
|
with the loadkeys ("man loadkeys") command.
|
|
|
|
You need at least one virtual terminal device in order to make use
|
|
of your keyboard and monitor. Therefore, only people configuring an
|
|
embedded system would want to say N here in order to save some
|
|
memory; the only way to log into such a system is then via a serial
|
|
or network connection.
|
|
|
|
If unsure, say Y, or else you won't be able to do much with your new
|
|
shiny Linux system :-)

depends on VT
|
|
---help---
|
|
The system console is the device which receives all kernel messages
|
|
and warnings and which allows logins in single user mode. If you
|
|
answer Y here, a virtual terminal (the device used to interact with
|
|
a physical terminal) can be used as system console. This is the most
|
|
common mode of operations, so you should say Y here unless you want
|
|
the kernel messages be output only to a serial port (in which case
|
|
you should say Y to "Console on serial port", below).
|
|
|
|
If you do say Y here, by default the currently visible virtual
|
|
terminal (/dev/tty0) will be used as system console. You can change
|
|
that with a kernel command line option such as "console=tty3" which
|
|
would use the third virtual terminal as system console. (Try "man
|
|
bootparam" or see the documentation of your boot loader (lilo or
|
|
loadlin) about how to pass options to the kernel at boot time.)
|
|
|
|
If unsure, say Y.

comment "Unix98 PTY support"

bool "Unix98 PTY support"
|
|
---help---
|
|
A pseudo terminal (PTY) is a software device consisting of two
|
|
halves: a master and a slave. The slave device behaves identical to
|
|
a physical terminal; the master device is used by a process to
|
|
read data from and write data to the slave, thereby emulating a
|
|
terminal. Typical programs for the master side are telnet servers
|
|
and xterms.
|
|
|
|
Linux has traditionally used the BSD-like names /dev/ptyxx for
|
|
masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
|
|
has a number of problems. The GNU C library glibc 2.1 and later,
|
|
however, supports the Unix98 naming standard: in order to acquire a
|
|
pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
|
|
terminal is then made available to the process and the pseudo
|
|
terminal slave can be accessed as /dev/pts/<number>. What was
|
|
traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
|
|
|
|
The entries in /dev/pts/ are created on the fly by a virtual
|
|
file system; therefore, if you say Y here you should say Y to
|
|
"/dev/pts file system for Unix98 PTYs" as well.
|
|
|
|
If you want to say Y here, you need to have the C library glibc 2.1
|
|
or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
|
|
Read the instructions in <file:Documentation/Changes> pertaining to
|
|
pseudo terminals. It's safe to say N.
