Building ports on old FreeBSDs - revised

This is a revision of an earlier post which has instructions that no longer work.

Are you running an older version of FreeBSD, and getting errors like this when you try to build a port?

"/usr/ports/Mk/bsd.port.mk", line 2416: warning: String comparison operator should be either == or !=
"/usr/ports/Mk/bsd.port.mk", line 2416: warning: String comparison operator should be either == or !=
"/usr/ports/Mk/bsd.port.mk", line 2416: Malformed conditional (((${OSVERSION} < 504105 || (${OSVERSION} 
    >= 600000 && ${OSVERSION} < 600103) || (${OSVERSION} >= 700000 && ${OSVERSION} < 700012)) && 
    ${PKGORIGIN} != "ports-mgmt/pkg_install") || exists(${LOCALBASE}/sbin/pkg_info))

If so, it's because the ports maintainers have started using expressions in the ports Makefiles which are not understood by the versions of make that come with old FreeBSDs.

The official recommended fix would be to upgrade your FreeBSD, but if that's not practical you can at least install a newer version of make to get by for a bit longer. This can be done in just a few minutes with two main steps: temporarily bring back an older /usr/ports/Mk which is compatible with FreeBSD 4.x - and then build and install the devel/make port which used to be present in the ports tree.

The ports tree is in CVS, so it's possible to checkout older revisions of selected directories. This FreeBSD Handbook page lists the anonymous CVS repositories available. For this example I'm going to use anoncvs@anoncvs1.FreeBSD.org:/home/ncvs We only need two small directories, so it probably doesn't really matter which one you use.

It seems like the first commit to the ports infrastructure which broke compatibility happened around Feb 5th, 2007 - so let's backup the current /usr/ports/Mk and check out one from Feb 4th:

cd /usr/ports
mv Mk Mk.original
cvs -d anoncvs@anoncvs1.FreeBSD.org:/home/ncvs co -D "04 Feb 2007" -d Mk ports/Mk

You should now be able to build some ports, at least those that don't use incompatible syntax in their individual Makefiles and don't require a newer ports infrastructure. Now, if you don't already have a devel/make port, use CVS to bring that back too, then build and install it:

cd /usr/ports/devel
cvs -d anoncvs@anoncvs1.FreeBSD.org:/home/ncvs co -D "04 Feb 2007" -d make ports/devel/make
cd make
make install
make clean

Lastly, set your system to use the new ports make in place of the old system make, and do some cleanup:

cd /usr/bin
mv make make.old
ln -s /usr/local/bin/make .

cd /usr/ports
rm -rf Mk
mv Mk.original Mk
rm -rf /usr/ports/devel/make

You should now be in better shape for trying to build new ports. 4.x isn't officially supported anymore by the ports maintainers, so there may be some individual port breakage - but at least you're over the first hurdle.

FreeBSD, OpenBSD, and 2007 Daylight Savings Time

Just a followup to my earlier post on updating FreeBSD to handle the changes in Daylight Savings Time starting in 2007....

There are a couple mentions [1], [2] on the freebsd-stable mailing list that the /etc/localtime file is binary compatible across various versions of FreeBSD.

This means you only have to get one good copy of /etc/localtime for your timezone, either by pulling from a FreeBSD 6.2 or higher machine, or installing the misc/zoneinfo port on one older machine and run tzsetup. Once you have that good version, you can copy it around to your other FreeBSD boxes, regardless of what version they're running.

This seems to also work between FreeBSD and OpenBSD (and perhaps Net and Dragonfly). I had a single OpenBSD 3.7 machine I wanted to update, and it seems to work OK to use a /etc/localtime pulled from a FreeBSD box. On OpenBSD (3.7 at least), /etc/localtime was a symlink to a file in /usr/share/zoneinfo/. I just removed the symlink and made a new one pointing to a new timezone file I stuck somewhere on the disk. Checking for the correct DST dates in OpenBSD seems to be the same as with FreeBSD:

zdump -v /etc/localtime | grep 2007

Look for March 11th as the start date.

Building ports on old FreeBSDs

The instructions in this entry no longer work, please check out the revised entry on this issue.

I've got a couple older FreeBSD machines at work, running 4.7 and 4.8, that have started having trouble building ports. Apparently some changes have been made to the ports infrastructure that are not compatible with make on older FreeBSDs. The error message given when a running 'make' in a port directory is:

"/usr/ports/Mk/bsd.port.mk", line 2292: warning: String comparison operator should be either == or !=
"/usr/ports/Mk/bsd.port.mk", line 2292: warning: String comparison operator should be either == or !=

     && ${PKGORIGIN} != "ports-mgmt/pkg_install")

"/usr/ports/Mk/bsd.port.mk", line 5987: if-less endif
"/usr/ports/Mk/bsd.port.mk", line 5987: Need an operator
make: fatal errors encountered -- cannot continue

I ran into this when trying to update timezone info. The problem can be fixed by installing a newer version of make on the system.

First, backup /usr/ports/Mk/bsd.port.mk

 cd /usr/ports/Mk
 cp -p bsd.port.mk bsd.port.mk.orig

Then patch it with this file or edit with your favorite editor going to line 2292 (the first error line above), where there's a chunk of .if .if....endif .endif statements and tossing everything except this first cluster of variables being set:

PKG_CMD?=              ${LOCALBASE_REL}/sbin/pkg_create
PKG_ADD?=              ${LOCALBASE_REL}/sbin/pkg_add
PKG_DELETE?=   ${LOCALBASE_REL}/sbin/pkg_delete
PKG_INFO?=             ${LOCALBASE_REL}/sbin/pkg_info
PKG_VERSION?=          ${LOCALBASE_REL}/sbin/pkg_version

save it. Now build and install a newer version of make, "Berkeley make, back-ported to FreeBSD 4.x"

cd /usr/ports/devel/make
make install
make clean


use it instead of the old make

cd /usr/bin
mv make make.old
ln -s /usr/local/bin/make .

restore the bsd.ports.mk file you backed up

cd /usr/ports/Mk
mv bsd.port.mk.orig bsd.port.mk

You should be able to build ports again using the current ports tree infrastructure.

2007 Daylight Savings Time changes and FreeBSD

Starting in 2007, the dates that daylight savings time begins and ends is changing in the US and other countries. For FreeBSD it seems versions 6.2 and higher should already know about the new DST dates. A machine can be checked with

zdump -v /etc/localtime | grep 2007

A machine with the old DST settings will show lines that begin with:

/etc/localtime  Sun Apr  1 07:59:59 2007 
/etc/localtime  Sun Apr  1 08:00:00 2007 
/etc/localtime  Sun Oct 28 06:59:59 2007 
/etc/localtime  Sun Oct 28 07:00:00 2007

which is wrong, (April 1st and Oct 28th). A machine that's correct should show:

/etc/localtime  Sun Mar 11 07:59:59 2007 
/etc/localtime  Sun Mar 11 08:00:00 2007 
/etc/localtime  Sun Nov  4 06:59:59 2007 
/etc/localtime  Sun Nov  4 07:00:00 2007

March 11th and Nov 4th being the new days that DST switches.

Updating a FreeBSD box seems to be just a matter in installing the misc/zoneinfo port, and then running the tzsetup command which gives you menus to pick your timezone again.

Full Text Searching with SQLite

I'd like to add a search feature back on this site. Previously, I had an arrangement setup with PyBlosxom and ht://Dig, but now that it's Django-powered, I'd like to do something that worked directly from the database instead of crawling the site like ht://Dig did.

After looking a while at various text search engines, I remembered seeing that SQLite just added an FTS1 module in version 3.3.8, which sounds pretty easy to use. Unfortunately the FreeBSD port databases/sqlite3 doesn't build with that feature.

After poking around a bit, I got it to build with FTS manually, and after a whole bunch more messing around, came up with a patch to add an option to the port to build sqlite3 with FTS. The patch has been submitted to the FreeBSD bug tracker as ports/106281. Hopefully I have all my ducks lined up on that.


Anyhow, in testing the FTS a bit, I found one thing they only hint at on the SQLite website. There's a Porter stemmer built in, even though the wiki says: "The module does not perform stemming of any sort." You activate it by adding tokenize porter to the table declaration, for example (adapted from their example).

CREATE VIRTUAL TABLE recipe USING FTS1(name, ingredients, tokenize porter);

once you've done that, and inserted some sample data:

INSERT INTO recipe VALUES('broccoli stew', 'broccoli peppers cheese tomatoes');

the searches don't have to be quite as exact, for example:

SELECT name FROM recipe WHERE ingredients MATCH 'pepper'

hits the 'broccoli stew' recipe even through it has 'peppers' and you searched for 'pepper'.

Not sure why the Porter stemmer isn't documented in the SQLite wiki, perhaps it's still a work in progress or being changed for FTS2.

Fibre Channel part 2

524 bytes per sector on a harddisk? That may work for some IBM RAID array, but FreeBSD isn't going to stand for it. After some searching, it appears the thing to do is to somehow change the sector size and do a low-level format.

Turns out Seagate has a very detailed manual on these drives, and it mentions that the sector size can be between 512 and 528 bytes. The sector size setting is apparently stored on a "SCSI mode page" 3, and the FreeBSD camcontrol utility has support for viewing/editing this. Running

camcontrol modepage da0 -m 3

shows:

Tracks per Zone:  7564 
Alternate Sectors per Zone:  0
Alternate Tracks per Zone:  20
Alternate Tracks per Logical Unit:  0
Sectors per Track:  784
Data Bytes per Physical Sector:  524
Interleave:  1
Track Skew Factor:  272 
Cylinder Skew Factor:  120
SSEC:  0
HSEC:  1
RMB:  0
SURF:  0

which is the current settings, and the same command with the addition of -P 2 to view the default settings shows:

Tracks per Zone:  7564
Alternate Sectors per Zone:  0
Alternate Tracks per Zone:  20
Alternate Tracks per Logical Unit:  0
Sectors per Track:  809
Data Bytes per Physical Sector:  512
Interleave:  1
Track Skew Factor:  272
Cylinder Skew Factor:  120
SSEC:  0
HSEC:  1
RMB:  0
SURF:  0

Those settings would be ideal. Notice how the smaller sector size gives more sectors per track. How to get the drive to switch to them? Adding a -e parameter to the camcontrol command as in: camcontrol modepage da0 -m 3 -e should allow for changing that modepage, but all I got back was: camcontrol: no editable entries. Running camcontrol modepage da0 -m 3 -P 1 to see the changeable values shows:

Tracks per Zone:  0
Alternate Sectors per Zone:  0
Alternate Tracks per Zone:  0
Alternate Tracks per Logical Unit:  0
Sectors per Track:  0
Data Bytes per Physical Sector:  0
Interleave:  0
Track Skew Factor:  0
Cylinder Skew Factor:  0
SSEC:  0
HSEC:  0
RMB:  0
SURF:  0

Dang, the IBM firmware has locked out making changes to the sector size. According to the Seagate manual:

The changeable values list can only be changed by downloading new firmware into the flash E-PROM.

Oh crap, where do you get new firmware, and how would you load it? Doesn't seem that Seagate has new firmware available for easy download (like you get with motherboards and such). Doing some digging with Google turned up some potential sources from deep within Sun and Grass Valley Group websites, but for all I know they're non-standard similar to how the IBM stuff is. This was not looking good.

Some more digging turned up this thread from a FreeBSD mailing list, which suggests setting a sector-size value and immediately reformatting the disk with:

camcontrol cmd da1 -v -c "15 10 0 0 v:i1 0" 12 -o 12 "0 0 0 8  0 0:i3 0 v:i3" 512
camcontrol cmd -n da -u 1 -v -t 7200 -c "4 0 0 0 0 0"

I wasn't sure if this was applicable to my particular FC drive, and would just changing the sector size also adjust the sectors-per-track or other possibly related settings? After doing a lot of reading on the camcontrol command, and various SCSI specs, I felt I had some understanding of what the above commands did, and figured it was worth a shot.

What do you know, it worked! There was a bit of trouble with the second camcontrol command in that it timed out too soon, but the sector size did change and it stayed changed. For my second drive, I tried the regular camcontrol format command instead of the raw one given in the example above.

camcontrol cmd da0 -v -c "15 10 0 0 v:i1 0" 12 -o 12 "0 0 0 8  0 0:i3 0 v:i3" 512
camcontrol format da0

That actually worked a bit better, because camcontrol format shows a nice progress display, instead of making you guess a timeout and waiting for while you hope it's working.

So now I've got a couple 10K rpm FC drives with FreeBSD installed and booting off them.

da0 at isp0 bus 0 target 120 lun 0
da0: <IBM-SSG S0BE146 3706> Fixed Direct Access SCSI-3 device 
da0: 100.000MB/s transfers, Tagged Queueing Enabled
da0: 140014MB (286749488 512 byte sectors: 255H 63S/T 17849C)
da1 at isp0 bus 0 target 124 lun 0
da1: <IBM-SSG S0BE146 3709> Fixed Direct Access SCSI-3 device 
da1: 100.000MB/s transfers, Tagged Queueing Enabled
da1: 140014MB (286749488 512 byte sectors: 255H 63S/T 17849C)

I noticed the smaller sector size gives more total space on the drive. They're fairly fast, but not life-changingly fast. It's been an interesting experience messing with them, but next time around I'll probably go back to SATA drives (or maybe SAS will be cheap on eBay by then....)

Fibre Channel

I'm going to be updating my home server soon, and I've often thought it would be nice to have some fast server-class harddisks for speed and reliability, maybe even arranged in a mirror because I've got a lot of stuff I wouldn't want to lose. A couple weeks ago I started looking into Fibre Channel gear that's available on eBay and was surprised to see how cheap some of this stuff was, with several 10k rpm and 15k rpm drives advertised as new going for 1/4 or less of the retail prices. I bit the bullet and bought a bunch of HBAs, cables, and drives for under $300.

The first HBA I got was a Qlogic QLA2000 for $1.99, which seems to be a stripped down version of the QLA2100 that has a 32-bit PCI interface instead of the 2100's 64-bit PCI-X setup. The machine I'm putting this into only has regular 32-bit PCI slots, so I'm not really loosing out on anything by using the cheaper card. Also got a QLA2200 which is a 64-bit card, but it works fine in a 32-bit PCI slot.

The drives are a pair of "new" 146.8GB Seagate Cheetah 10K.7 drives, part # ST3146707FC with an IBM label on them for $230 total. To buy the SCSI versions of those drives from NewEgg at today's price would cost $430 each, so I've saved over $600 by going this route. However, I entered one of the drive's serial numbers into Seagate's warranty webpage, and found that it's not eligible for warranty through them - you must go through the OEM they sold the drives to (IBM in this case). Did some poking around on IBM's site and it's not obvious if/how you'd get warranty service through them. I guess that's the price you pay buying this type of drive.

A 5-pack of HSSDC-DB9 cables was just $20, and the final piece was a "Start" T-Card directly from CK Computer Systems for $34. (the FAQ on that site was really helpful)

Basically just plugged it all together, and fired the machine up. The Qlogic card shows a BIOS boot message saying to hit ALT-Q to get into their setup. There's one part in their BIOS utility where it scans your loop for devices - it showed the card, and then 15 blank spots. I thought I was screwed at first, but after hitting page down several times I found the drive at id 120. Wow, FC can handle a lot of devices compared to SCSI.

Booted FreeBSD 6.1 (already installed on a regular ATA disk), and saw it detect the Qlogic card with the isp(4) driver, and a da0 drive. Once I saw that working, I tried adding ispfw_load="YES" to /boot/loader.conf. On the next reboot, it paused after it detected the isp card, presumably loading the firmware that comes with FreeBSD. The relevant dmesg parts are:

isp0: <Qlogic ISP 2100 PCI FC-AL Adapter> port 0xce00-0xceff mem 
      0xfe7df000-0xfe7dffff irq 17 at device 2.0 on pci2
isp0: [GIANT-LOCKED]
----
da0 at isp0 bus 0 target 120 lun 0
da0: <IBM-SSG S0BE146 3709> Fixed Direct Access SCSI-3 device
da0: 100.000MB/s transfers, Tagged Queueing Enabled
da0: 137501MB (275154368 524 byte sectors: 255H 63S/T 17127C)

The camcontrol utility seems to work with the HBA/drive combination no problem at all. However, when I tried to do a fdisk /dev/da0 it errored out with:

fdisk: can't read fdisk partition table
fdisk: /boot/mbr: length must be a multiple of sector size

Oops, didn't like the 524 byte sectors. I'll cover how I dealt with that in part 2.

USB GPS on FreeBSD

A while ago I picked up a Holux GR-213U USB GPS receiver for pretty cheap on eBay. It's worked well in Windows, even on Windows within-a-Mac using Parallels. I thought I should give it a try using gpsd on FreeBSD, since I see nobody's reported it as working or not on their hardware page.

Stuck it into one of my FreeBSD 6.1 boxes, and saw in /var/log/messages:

ugen0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 2

That sounded pretty good, never messed with USB serial on FreeBSD before, so wasn't sure if the /dev/ugen0 device was what gpsd needed to talk to. Turns out it wasn't. After digging for a while, tried

kldload uplcom

and then unplugged/replugged the USB receiver - and now it shows up as

ucom0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 2

and a /dev/cuaU0 device showed up. I guess that makes sense in now that I see it working. The uplcom(4) module is required because the device is a Prolific chip, and that module also brings in the ucom(4) module automatically which provides the tty interface (/dev/cuaU*) gpsd needs to operate. Other USB serial devices might require a different modlue than "uplcom" - the SEE ALSO section of the ucom man page shows other possibilities.

Tried running gpsd in debug mode with

gpsd -N -n D 2 /dev/cuaU0

and was rewarded with lots of output from the receiver. Ran "cgps" and saw a human-friendly display of the GPS readings, but it kept flipping between 2D and 3D fix. Not sure what that's about yet, but at least the USB connection is working.

"touch: not found" in installworld

I've been updating one of my servers from FreeBSD 6.0 to 6.1, and had done a make buildworld a weeek or so ago, but didn't get around to actually installing it at the time. Since then, I cvsup'ed the source again, and the only real change was in /etc/rc.d/jail. I figured I didn't need to buildworld again since it's just a shell script, doesn't get compiled, and is installed by mergemaster (instead of make installworld).

When I did make installworld on my slightly outdated world, it errored out almost right away with: "touch: not found". The FreeBSD FAQ mentions that:

This error does not mean that the touch(1) utility is missing. The error is instead propably due to the dates of the files being set sometime in the future. If your CMOS-clock is set to local time you need to run the command adjkerntz -i to adjust the kernel clock when booting into single user mode.

I wasn't in single user mode, and the clock was correct - however my /usr/src/sys/conf/newvers.sh file was dated later than the world I had built, and that seemed to be causing the error. Using touch(1) to set the date back on that one file to match the world seems to have fixed the problem.

Portaudit and ezjail

Portaudit is a handy utility for FreeBSD that lets you know if any of your installed ports has a known security vulnerability. Part of the install puts a script in /usr/local/etc/periodic/security, which adds a report on ports that should be updated, to the daily security e-mail the system sends to root.

If you have jails setup on your machine, they may have their own ports installed which you'd probably also want checked by portaudit. The brute-force way to do it would be to install separate copies of portaudit inside each jail, and keep an eye on separate daily security e-mails from each jail looking for problems.

In my case, I've been running jails setup by ezjail, and didn't want to install portaudit over and over again. Instead, I came up with this minor shell script that checks each ezjail. If you save it as /usr/local/etc/periodic/security/410.portaudit_ezjail, then it'll run each day, right after the main portaudit periodic script that updates the vulnerability db and checks the main machine, and include the output in the main machine's security e-mail.

            su -fm "${daily_status_security_portaudit_user:-nobody}"
                done
        ;;

I have to admit I'm not too fluent with shell scripting, and would have been much more comfortable writing it in Python, but that's probably a bit of overkill in this case.


Doh! As soon as I finished writing this, I happened to check the ezjail website, and found a link to jailaudit, by Philipp Wuensche which looks to do a similar thing but with more options, and has been submitted as a port.
