This commit updates both README.md and the nwipe(8) manpage to reflect the
features and behaviour introduced in the upcoming v0.40 release. Changes include:
- Added documentation for the new AES-256-CTR PRNG and its hardware-accelerated
implementation.
- Updated erasure method list to include the BMB21-2019 State Secrets Bureau
sanitisation standard.
- Added full documentation for large, aligned I/O buffers and their impact on
performance.
- Documented the new I/O mode system (`--io-mode=auto|direct|cached`,
`--directio`, `--cachedio`) and the interaction with O_DIRECT fallback logic.
- Updated sync behaviour description to match the new byte-accurate scaling for
cached I/O.
- Updated PRNG section to remove the “future release” note for AES-CTR.
- Documented improved device exclusion with `/dev/disk/by-id/*` support.
- Updated seeding description to reflect the use of `getrandom()` instead of
`/dev/urandom`.
- Refreshed dependency lists and provided concise installation instructions for
multiple Linux distributions.
- Minor stylistic cleanup, clarification of SSD limitations, and improved README
structure for readability and accuracy.
You can now specify --pdftag to enable the
display of system UUID and system serial
number information on the PDF report.
Nwipe defaults to not displaying system IDs
but some users like to record the system UUID
or serial number on the Erasure Report along
with the disk information.
Manpage is named nwipe.1 which would be correct but manpage
contains section 8 which forms a mismatch(warning) in Debian.
# Man sections
1 Executable programs or shell commands
2 System calls (functions provided by the kernel)
3 Library calls (functions within program libraries)
4 Special files (usually found in /dev)
5 File formats and conventions, e.g. /etc/passwd
6 Games
7 Miscellaneous (including macro packages and conventions), e.g. man(7), groff(7), man-pages(7)
8 System administration commands (usually only for root)
9 Kernel routines [Non standard]
(requested by MvB)
Anonymize the serial numbers in the gui, the
log and the summary table.
If a serial number was obtained from the device,
it is replaced with "XXXXXXXXXXXXXXX".
If the serial number could not be obtained from the
device, it's replaced with "???????????????".
If you use the option --nousb, all USB devices will be ignored.
They won't show up in the GUI and they won't be wiped if you use
the --nogui --autonuke command. They will even be ignored if you
specifically name them on the command line.
Add verbose option -v, --verbose
Only display thread cancellation info messages, excluding error
messages, only when verbose option is selected.
This helps to keep the log a bit cleaner especially when wiping many
drives simultaneously.
Also fixes an issue where program exits when terminal resized but
only after all the wipes have finished. You can now resize the
terminal, before, during and after the wipes have completed and
the windows are now all correctly updated and sized.
Updated version to 0.28-pre-release
Removed unnecessary zero of gui thread pointer.
Created six new functions in gui.c in order to fix the above problem
and reduce existing duplicated code.
I could not find the original specification of this standard, although
many proprietary implementations exist (or claim to exist). Also there
are many 3rd-party descriptions of the method, which often differ in one
or another detail, but after some reading I could conclude that the most
likely definition should be as follows:
1. Fill the device with zeroes, do not verify.
2. Fill the device with ones, do not verify.
3. Fill the device with a PRNG stream, do verify.
In other words, this is a simplified version of nwipe's "dodshort".
Both display_help() and nwipe_options_parse() are consistent about the
--noblank option, in that it exists and has no short form. Make the man
page and nwipe_gui_noblank() indicate that correctly. Mention that "ops2"
never blanks the device regardless of the option.
