avoid overflows in kernel/time.c
When the conversion factor between jiffies and milli- or microseconds is
not a single multiply or divide, as for the case of HZ == 300, we currently
do a multiply followed by a divide. The intervening result, however, is
subject to overflows, especially since the fraction is not simplified (for
HZ == 300, we multiply by 300 and divide by 1000).
This is exposed to the user when passing a large timeout to poll(), for
example.
This patch replaces the multiply-divide with a reciprocal multiplication on
32-bit platforms. When the input is an unsigned long, there is no portable
way to do this on 64-bit platforms there is no portable way to do this
since it requires a 128-bit intermediate result (which gcc does support on
64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but
since the output is a 32-bit integer in the cases affected, just simplify
the multiply-divide (*3/10 instead of *300/1000).
The reciprocal multiply used can have off-by-one errors in the upper half
of the valid output range. This could be avoided at the expense of having
to deal with a potential 65-bit intermediate result. Since the intent is
to avoid overflow problems and most of the other time conversions are only
semiexact, the off-by-one errors were considered an acceptable tradeoff.
At Ralf Baechle's suggestion, this version uses a Perl script to compute
the necessary constants. We already have dependencies on Perl for kernel
compiles. This does, however, require the Perl module Math::BigInt, which
is included in the standard Perl distribution starting with version 5.8.0.
In order to support older versions of Perl, include a table of canned
constants in the script itself, and structure the script so that
Math::BigInt isn't required if pulling values from said table.
Running the script requires that the HZ value is available from the
Makefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the
architectures which didn't already have it (alpha, cris, frv, h8300, m32r,
m68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or
sh64 architectures, since Paul Mundt has dealt with those separately in the
sh tree.

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 :-)

The system console is the device which receives all kernel messages
|

|
|
|

|
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.)
|
|

|
|
|
|
|
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.
