mksh R36 released!

25.10.2008 by tg@
Tags: mksh

The MirBSD Korn Shell R36 has been released yesterday; the Changelog contains more details as usual.

Major changes:

  • Digital UNIX (DEC OSF/1) V2.0 (MIPS) is now supported using the DEC C and ucode toolchain. (We could not run the testsuite, though.)
  • The ‘-Q’ option to Build.sh is gone without replacement.
  • A new option can be enabled by adding -DMKSH_BINSHREDUCED to $CPPFLAGS, intended mostly for Debian. This option adds extra code to determine whether mksh(1) is called as sh or -sh and switch to “set -o posix” mode if so, disabling brace expansion and some security features, because legacy scripts, such as debconf, depend on such reduced functionality /bin/shs.
  • Input lines beginning with an IFS character of IFS white space are no longer pushed into the history. Some other, less surprising, changes were also made to both Emacs and Vi command line editing modes.
  • The arc4random.c contributed file is now stored with the RCS version number appended, and has been updated.

This is a major update with improved stability and compatibility, and as such recommended in general. It has undergone more extensive testing than mksh R35; if there still be bugs, please report to us. Note that some sorts of behaviour are not considered bugs but expected, sometimes due to historical, sometimes compatibility reasons.

Request for Assistance: We are still looking for an OpenBSD committer to import mksh into the ports tree. Furthermore, a Slackware GNU/Linux package is still missing, as well as a PC-BSD PBI, and Macports (former Darwinports) do not carry mksh either. My earlier Minix 3 problem persists, as do the Plan 9 and Syllable Desktop ones.

Bugs in the current snapshot

26.07.2008 by tg@
Tags: snapshot bug

The following bugs are known in the MirOS #10-current snapshot, dated 2008-07-22:

  • The user shell for the default “live” user is /usr/dbin/mksh, which however has been optimised away. This is a bug in the production of this one snapshot and easy to fix in future issues. Workaround: while the rc.netselect script runs, choose ‘9’ to escape to a shell, and change the “live” user’s shell using vipw(8)chsh -s /bin/mksh live might also work, but has not been tested.
  • Running “startx” does not work because /usr/X11R6/bin/X is no symbolic link but a copy of the XFree86® server itself (on other baselive CDs it was a hard link instead of a copy; the change is due to production differences, but both break startx(1) and xinit(1)). Workaround is to use xdm(1) instead or try: startx -- /usr/X11R6/bin/XFree86 :0
  • The X11 server may not switch to graphics mode on the ALIX.1c board.

We apologise for the inconvenience caused, and will try to solve these issues in the next development snapshot.

MirOS Project @ FrOSCon 2008

Tags: event

The MirOS Project will show up with both developers to run a booth at FrOSCon; we will be giving away Live CDs (either #10-stable or #10-current) and flyers. You will be able to meet us and a few helpers (known from IRC and mailing lists) there, chat about mksh, have a beer, fun, whatever.

This year, one of the two XFree86® developers will also attend; you can probably meet him at our booth.

MirOS-current DuaLive snapshot on BT

22.07.2008 by tg@
Tags: snapshot

The 2008-07-22 snapshot of MirOS BSD/i386 #10-current has been released as a new-style dualive CD image (BaseLive + Install CD for i386, Install CD for sparc, build logs, a selected few binary packages and their distfiles, but nothing fancy) on the usual BitTorrent tracker, multi-tracked with a major BT site for these who pick it up there.

It's also available for NetInstall on both architectures. Note that /MirOS/ has been cleaned up a little: some old NetInstall or upgrade packages are removed.

The #10/i386 binary packages should all be installable on this snapshot, although it does come with more recent MirPorts Framework and a couple of current binary packages as well.

The MirBSD Korn Shell R35 has just been released; as per the Changelog this is a major update with some bugfixes, a lot of new features, and licence simplification (the advertising clause is gone). This version was not tested on AIX, BSD/OS, Interix, IRIX, GNU/kFreeBSD, UWIN, the Intel compiler, but we expect no regressions on these platforms either. New supported platforms include dietlibc, LLVM. Platforms already working continue to be MirOS BSD, DragonFly BSD, FreeBSD, MidnightBSD, NetBSD, OpenBSD, DEC ULTRIX, Mac OSX, HP Tru64, HP-UX, Solaris, Debian GNU/HURD, Cygwin, and various GNU/Linux systems; using gcc, pcc, SUNWcc, llvm-gcc, Compaq C, HP aCC, TenDRA; on a variety of hardware architectures.

Online manual: HTML, PDF (ISO A4 paper, we don’t support Imperial units, as even the USA has converted to Metric)

Update 18.07.2008 – mksh R35b is out, with major bug fixes, read the changelog.

As mentioned on the Downloads page, the naming scheme of the anoncvs mirrors changed, multiple times.


Tags: security

The CVE-2008-1447 does not, according to various sources, affect systems that randomise their source port. MirOS libc’s integrated resolver, according to some OpenBSD developers, does this, as does DJBDNS. The net/bind mirport is affected, but by using pf(4) to NAT yourself (thanks to Vutral for the suggestion), you can randomise these ports too. According to RUS-CERT, only using DNSSEC is a fix… I wonder if this is truth or advertising for a technique without wide-spread use.

update for 2008-05-14 snapshot available

15.05.2008 by tg@
Tags: snapshot

The fixes10.ngz set, of course gzsig(1)d, contains an updated mksh binary and dot.mkshrc as well as /.profile (root) and /etc/profile (user) files, which speed up logins, as well as an updated /etc/ssh/ssh_known_hosts file. It can be directly applied from the installer, or untarred in / (do not forget the 'h' and 'p' options to tar(1)). Note that this will overwrite any existing changes to these files:

  • /.profile
  • /etc/profile
  • /etc/skel/.mkshrc
  • /etc/ssh/ssh_known_hosts

Use this for integrity checking:
RMD160 (fixes10.ngz) = 6c85c3e8eb4a5046b5b45373a0996cee2a3208b7

Our anoncvs mirror has changed its ssh host keys due to a Debian-specific problem (it's hosted on a machine running Debian GNU/Linux courtesy of gecko2@). The new keys are: [Update: [old broken link removed] moved]

Please copy these into /etc/ssh/ssh_known_hosts or ~/.etc/ssh/known_hosts, overriding the existing keys for the same IPs or host names.

The current version of the /etc/ssh/ssh_known_hosts file can be retrieved via anonymous CVS (from the server affected), anonymous rsync (also from rsync.allbsd.org), CVSweb (from both servers) or by an eMail request.

Yesterday's snapshot does not yet include the new public host keys, as they were generated only today.

MirOS-current snapshot on BT

14.05.2008 by tg@
Tags: snapshot

The 2008-05-14 snapshot of MirOS BSD/i386 #10-current has been released as a simple baselive CD image (Live + Install CD, build logs, but nothing fancy) on the usual BitTorrent tracker, multi-tracked with a major BT site for these who pick it up there.

It's also available for NetInstall, although you shouldn't pick up the perl CVS fix in that directory, as it applies to a much older #10-beta snapshot.

The #10/i386 binary packages should all be installable on this snapshot, although it does come with more recent MirPorts Framework.

mksh, mirmake, pkgtools upgraded

12.04.2008 by tg@
Tags: mksh mirmake

The MirBSD Korn Shell R33d has been released, mostly containing a security fix for the -T option, see the Changelog for details.

A new MirMake version has been issued, to fix problems compiling C++ code with strange file extensions (.cpp as on Microsoft® Windows®, and .C as BOINC uses). MirMake is a sort-of-portable version of the MirOS make(1) utility, a few header files and a libmirmake.a containing helper functions, and some supporting utilities: install(1) lndir(1) lorder(1) mkdep(1) readlink(1) tsort(1)

The MirPorts Package Tools have been updated as well, as Lucas “laffer1” Holt, the MidnightBSD founder, has implemented ldconfig(8) -U too, and the use of this option by pkg_create(1) is now required for a lot of packages (since GNU libiconv, expat and libpng use their own fake-pkgview subdirectories.
