* Remade patch so it works with minix patch tool.
* New MINIX tar support -ox, so revert back to it
In fetch scripts, tar had been replaced by bsdtar as the prebvious
tar did not support the -o flag under minix, which is required to
prevent usage of tar file stored user and group information.
This introduces portability problems. As our new tar tool now
support that flag revert back to improve portability.
upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
* Removing commands/tar
* Updated external/bsd/libarchive
* Adding external/bsd/libarchive/bin/tar compiled bsdtar instead
of just tar
* (tar is taken care of through the pax utility)

This is a security measure. We may want to bring back user access to
mounting and formatting media in the future, but this should be done
only once we are sure that this is safe from a security perspective.
As of this patch, df(1) no longer performs raw disk access; it
operates exclusively on mounted file systems. This also means
that df no longer needs to be setuid.
We have actually had lseek64 for quite a while now, so it's no longer
necessary to do horrible things to the partition table just to be able
to access large offsets into a device.
Also fix the compiler warnings in these commands.
- inherit a predefined set of system environment variables
(the current set of inherited variables is: ahci; acpi; no_apic);
- auto-adjust the default menu option when lines are auto-removed;
- add variable substitution support for /etc/boot.cfg.local;
- make default menu options in boot.cfg.local relative to itself,
allowing one to set the default to a menu option from this file.
. Removed the usage of 64 bit functions in top.c. Compiles successfully.
. Scaling 64 bit values to 32 bit is removed.
. Retain make64 instead of using | with shift.
. Add order cycling display
lets unstack
(a) know about in-kernel ipc entry points and
(b) be able handle >2GB symbol offsets.
. sort: add -x for hex numerical sort
. unstack: gnm is obsolete
. unstack: datasizes is obsolete (use nm --size-sort instead)
. unstack: add ipc entry points read from procfs (hex)
. unstack: use sort -x to sort symbol order so the procfs ones are
sorted independent of position and original ordering
complete munmap implementation; single-page references made
a general munmap() implementation possible to write cleanly.
. memory: let the MIOCRAMSIZE ioctl set the imgrd device
size (but only to 0)
. let the ramdisk command set sizes to 0
. use this command to set /dev/imgrd to 0 after mounting /usr
in /etc/rc, so the boot time ramdisk is freed (about 4MB
currently)
This patch adds the sprofdiff tool, which compares two sets of profiling
output files. It sorts processes and symbols by difference in average
number of samples, placing those that took more time on the left first
and those that took more time on the right last. If multiple runs are
combined, a standard deviation is computed and this is used to compute
the significance level, which gives an indication of which differences
are likely to be due to chance.
This tool is run not on the raw profiling files, but on the output of
sprofalyze -d (a new option). Though having to use two tools and an
intermediate file seems a bit awkward, the advantage is that the
original source tree is not needed to resolve the symbols. For
comparisons, this is very useful. Also, the intermediate file is in a
text format that can easily be processed by scripts, which may be useful
for other purposes as well.
