liamjfoy 0590732532 Document new -P behaviour 2006-08-25 11:08:50 +00:00
liamjfoy c9432db8c8 Only remove the file if the file can be successfully
overwritten. Old code would remove the file regardless of
whether the overwrite was successful or not.

New behaviour:

carpy: {12} touch moo ; chmod 444 moo
carpy: {13} ls
moo
carpy: {14} rm -P moo
rm: moo: -P was specified but file could not be overwritten
carpy: {15} ls
moo
carpy: {16}

tls e9e0ca4155 Change behaviour of -P option to conform generally to DoD 5220.22-M
standard.  This change inspired by Apple's "Secure Empty Trash" functionality
in MacOS 10.3.  However, it is important to understand that this change
does not -- and can not -- actually achieve conformance to the current
revision of the standard.  To quote the manual page:

     The -P option attempts to conform to U.S. DoD 5220-22.M, "National Indus-
     trial Security Program Operating Manual" ("NISPOM") as updated by Change
     2 and the July 23, 2003 "Clearing & Sanitization Matrix".  However,
     unlike earlier revisions of NISPOM, the 2003 matrix imposes requirements
     which make it clear that the standard does not and can not apply to the
     erasure of individual files, in particular requirements relating to spare
     sector management for an entire magnetic disk.  Because these
     requirements are not met, the -P option does not conform to the standard.

This also makes the -P option a *lot* more expensive than it used to be.
It used to overwrite with 0xff, overwrite with 0x00, overwrite with 0xff,
with an fsync after each write.  Now it overwrites with a random character,
overwrites with 0xff, overwrites with 0x00, reads to validate the 0x00
overwrite, then overwrites with random data -- calling sync() after every
operation in an attempt to force seeks that will clear the data from the
cache of disks that lie about whether data has been committed to the
platters.  Also, the file's opened with O_SYNC|O_RSYNC to cause metadata
updates on every read/write, which should cause still more seeks.

This is better than it used to be, but it's by no means adequate if you
have data you really don't want read by an adversary who can pull the
disk apart.

jschauma 458ed23412 As discusses a little while back on tech-userlevel:
If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.

While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.

files in case the `-f' option has been specified:
Extend the definition of `non-existent' to include ENAMETOOLONG and ENOTDIR
cases, since file names failing with these errors can safely assumed to be
non-existent.  Fixes PR bin/2993.

jtc 23e6aab105 Use "utility" instead of "command". Modern definitions of these terms
are distinct (See POSIX.2 glossary).

A utility is a executable, script or shell builtin; while a command
can be any of those things plus lists, pipelines, compound commands
(if, for, while) and shell function definitions.

jtc 1a6ccc3e14 Strip trailing slashes of operands in checkdot().
POSIX.2 requires that if "." or ".." are specified as the basename
portion of an operand, a diagnostic message be written to standard
error, etc.  We strip the slashes because POSIX.2 defines basename
as the final portion of a pathname after trailing slashes have been
removed.

This also makes rm "perform actions equivalent to" the POSIX.1
rmdir() and unlink() functions when removing directories and files,
even when they do not follow POSIX.1's pathname resolution semantics
(which require trailing slashes be ignored).
