Subject: fd(4) missing from 2.11BSD (#363)
Index: sys/ufs_syscalls.c,sys_inode.c,many-others 2.11BSD
Description:
1) The file descriptor driver is not present in the system.
2) The setup documentation's estimate file sizes for the distribution
(boot) tape is out of date.
Repeat-By:
1)
ls -l /dev/stdin /dev/stderr /dev/stdout /dev/fd
Observe that a 'not found' error message is printed.
Alternatively one can try to use /dev/fd/0:
2)
Observation or have it pointed out by someone installing the system
and wondering if the tape was successfully read.
Fix:
#2 was simply a matter of updating the record counts in one chapter
of the documentation. It had been a long time since the estimated
counts were generated by scanning a tape and the system has grown
quite a bit since then. The growth had been to the point where the
documentation's estimates were low enough to cause concern in some
cases when reading the tape.
#1 started out as "simply port the fdopen()" routine from the 4.4-Lite2
CD. The port did not stay simple for very long. Thankfully the
"snowball factor" was not _too_ big but the number of files changed
did grow from one or two to about 26.
What is fd(4) and why would one use it?
It is a pseudo-driver (no physical hardware is present) that clones
currently open file descriptors. The pathname "/dev/fd/0" (/dev/stdin
is another name for the same device) can be passed as an argument to
programs that are not set up to read from 'stdin'. The assembler
used to be a good example of this ('as' has since been rewritten but
for now assume that 'as' does not read 'stdin'), a pipeline of the
form:
/lib/cpp -E foo.c | sed ... | as -o foo.o
would not work because 'as' expected all files to be on the command
line. With fd(4) present in the system the pipeline above would be
rewritten as:
/lib/cpp -E foo.c | sed ... | as -o foo.o /dev/fd/0
Or perhaps you want to interleave 'stdin' input with a data from other
files as the data is sent to a program. This could be done with
temp files:
cp foo /tmp/xxxx
inputfilter bar >> /tmp/xxxx
cat baz >> /tmp/xxxx
program /tmp/xxxx
With fd(4) present you could simply:
inputfilter bar | program foo /dev/stdin baz
Some files (ufs_syscalls.c and ufs_syscalls2.c for example) underwent
additional minor changes to relocate a couple functions. This was
done because large monolithic modules are becoming increasingly hard
to fit into 8kb overlays.
The most drastic change was to the 'open' and 'close' handling of
file descriptors. The "open()" routine was essentially ported from
4.4-Lite2 changing references to "vnodes" into references to "inodes".
The "close()" function was modified so that pipes and inodes no longer
share as much common logic. The two file types are different enough
that attempting to share the ino_close routine added rather than
reduced the complexity of the code.
The code to actually implement the 'fd' driver is perhaps 60 lines
in kern_descrip.c. All the other changes were "infrastructure"
needed to support the new driver.
Overall growth of the kernel is extremely small. The code space only
grows by about 300 bytes. In fact the D space actually shrank by
2 bytes. This was possible because several error message strings were
shortened and a couple diagnostic checks were removed (they were left
over from debugging the file locking changes years ago).
Even though the overall size of the kernel did not change greatly
two of the Makefiles in the kernel build had to change for two reasons:
the overlay layout needed to be changed and a new file (vfs_vnops.o)
was added to the kernel.
You will need to modify "Make.sys" for all locally built kernels. Also
the overlay layout may need to be changed in local kernel build
directories. The GENERIC kernel is taken care of by the provided
patches. Use the changes in GENERIC/Makefile and GENERIC/Make.sys
as guides.
The attached shar file contains:
/tmp/363.shar
/tmp/363.patch
The first contains the new files being added to the system and the
second contains the changes to existing files.
To install the update KIT cut where indicated saving to a file
(/tmp/363). Then:
cd /tmp
sh 363
sh 363.shar
patch -p0 < 363.patch
Then for each locally configured kernel (NOT including GENERIC!)
cp /sys/conf/Make.sys /sys/YOUR_KERNELS/Make.sys
Next you need to adjust /sys/YOUR_KERNELS/Makefile and add the file
'vfs_vnops.o' to the list of object files. IF there is room you can
add 'vfs_vnops.o' to the same overlay (or base segment) as the file
'ufs_syscalls.o'. Otherwise you need to find an overlay with about
500 bytes of space left (overlays can be 8192 bytes maximum).
Now recompile the kernel(s):
Recreating the GENERIC kernel is optional but is a good idea:
cd /sys/GENERIC
make clean
make
install -c -m 744 -o root unix /genunix
cd /sys/YOUR_KERNEL
make clean
make
make install
The /dev/ entries are made next:
cd /dev
./MAKEDEV fd
reboot
After the system comes back up the manpage for fd(4) is installed:
cd /usr/src/man/man4
/usr/man/manroff fd.4 > fd.0
install -m 444 fd.0 /usr/man/cat4/fd.0
cd /usr/man/cat4
ln fd.0 stdin.0
ln fd.0 stderr.0
ln fd.0 stdout.0
Congratulations - you're done.

YXIf the file descriptor is open and the mode the file is being opened

YX.sp
YX.in +0.5i
YXfd = open("/dev/fd/0", mode);

YXand the call:
YX.sp
YX.in +0.5i
YXfd = fcntl(0, F_DUPFD, 0);
YX.in -0.5i
YX.PP
YXare equivalent.
YX.PP
YXOpening the files
YX.IR /dev/stdin ,

YX.I /dev/stderr
YXis equivalent to the following calls:
