9.1 - 9.2 upgrade, clang question
When upgrading from 9.1 to 9.2 using source, is there any benefit to rebuilding twice, due to the clang version change? So that the second buildworld/kernel is done from the updated clang 3.3, instead of the clang 3.1 that was in FreeBSD 9.1? -- Thanks, Dean E.

Just read your mail. I will have to take some time, to look into what you have said, as I have not yet used the concepts that you spoke about.

The kernel has its own crash handling and will initiate the writing of the proper image automatically. It will be stored on the partition designated by the /etc/rc.conf setting dumpdev=device, usually a swap partition, and at next boot time that image will be written to a file in /var/crash, if nothing else has been defined with dumpdir=directory (same file; see man rc.conf and /etc/defaults/rc.conf for details). If you want to coredump to a USB device, you need to configure this accordingly.

Can clang be educated to refer gcc48 headers, installed via pkg_add?

There two C++ runtime libraries, the old gcc libstdc++ which is used by
default and the new C++11 libc++. You can use the latter like this:

Fwd: c++11 question: clang++ 3.3 future header not found
AFAIK, the easiest way to get C++11 support in clang is to use libc++ (see
http://blogs.freebsdish.org/theraven/2013/01/03/the-new-c-stack-in-9-1/).

Re: kern_jail_set() Error Scenario Question
On 08/22/13 17:46, Matt Miller wrote:
We ran into the following scenario in an application recently and were
wondering if the behavior of kern_jail_set() is as expected here.
This was an application bug where we were in, say, the JID 1 context
and tried to call jailparam_set() with the flags (JAIL_CREATE |
JAIL_UPDATE) and the jid param set to 1. The basic idea was to
create or update JID 1 with some params, but the error was we were
already in the JID 1 context. So, our understanding is this shouldn't
work since JID 1 already exists and you can only modify it from a
proper ancestor.
However, rather than getting an error back from jailparam_set(), it
ended up creating a second prison with JID 1, so there were two
prisons existing with JID 1 at that point. This is based on 8.2.0
code, but, at first glance, it looks like the logic causing this may
be the same in head.
Looking at kern_jail_set(), what happens here is:
1. We find a prison with JID=1, however since it's not a proper child
we set pr = NULL in line 1024:
1011 pr = prison_find(jid);
1012 if (pr != NULL) {
1013 ppr = pr-pr_parent;
1014 /* Create: jid must not exist. */
1015 if (cuflags == JAIL_CREATE) {
1016 mtx_unlock(pr-pr_mtx);
1017 error = EEXIST;
1018 vfs_opterror(opts, jail %d
already exists,
1019 jid);
1020 goto done_unlock_list;
1021 }
1022 if (!prison_ischild(mypr, pr)) {
1023 mtx_unlock(pr-pr_mtx);
1024 pr = NULL;
1025 } else if (pr-pr_uref == 0) {
2. Since pr is NULL, we create a new prison. Since the jid is not
zero, we insert it in the list and set its pr_id. At this point, we
have two prisons with a JID of 1 and the same parent prison.
1166 /* If there's no prison to update, create a new one and
link it in. */
1167 if (pr == NULL) {
...
1185 pr = malloc(sizeof(*pr), M_PRISON, M_WAITOK | M_ZERO);
1186 if (jid == 0) {
...
1212 } else {
1213 /*
1214 * The jail already has a jid (that did
not yet exist),
1215 * so just find where to insert it.
1216 */
1217 TAILQ_FOREACH(tpr, allprison, pr_list)
1218 if (tpr-pr_id = jid) {
1219 TAILQ_INSERT_BEFORE(tpr,
pr, pr_list);
1220 break;
1221 }
1222 }
...
1229 pr-pr_parent = ppr;
1230 pr-pr_id = jid;
We wanted to see if this is per design or a situation that should
avoid creating the second prison and return an error.
That's definitely not per design. I'll try reproducing this, and put in
correct logic. The proper response is indeed an error: ENOENT, because
from inside the JID 1 context you shouldn't be able to see jail #1 (you
can't operate on your own jail).

RE: Pre-sales question
Sir: I would like to know if your freebsd OS 9.1 suite on CD(DVD) can be installed, and then run, on a Dell Inspiron 531S? I looked-over your website, and did not see a citation for that specific PC (though I did see it for others). For your reference, my PC has a AMD Athlon(tm) 64 X2 Dual core processor 3800+ 2.01 GHz. The operating system on it right now (Vista) is 32-bit. The PC can have up to 4GB of RAM. I have a 80GB Hard drive on it right now. I would like to hitch it to the PC using a USB cable. If version 9.1 does run on that machine, then I may order a copy for myself.

Question about usbhid.h and dev/usb/usbhid.h
Hi, I'm currently writing a USB driver for the SFML framework. I'm reading the code of SDL and seen the usage of usbhid. However, /usr/include/usbhid.h and /usr/include/dev/usb/usbhid.h are different. But they have both some common functions and the same data definition. For instance, enum and structures are identical, but the second one has much more #define about hid usages. Why are these files so much different and still having some identical definitions? Isn't better to add full definitions and data to the second one and just add a #include dev/usb/usbhid.h in /usr/include/usbhid.h?

As a side discussion... (opening a can of squiggly worms here) It's often bothered me that the tools don't know about the archive (which goes back a long ways and has a very consistent and structured layout). So in authoring the latest tool (bsdconfig(8)), I made sure that the archive is checked (grep archive media/ftp.subr from SVN r247280). Don't know if that was the right move, but here @ Vicor, we've been [ab]using the archive for .. over a decade? (looks at julian to chime in if he used the archive before I got here). But I for one would like to see the archive to maintain its steady growth and be available. Of course, the change to look in the archive seemed (to me at least) to be a pretty innocuous one (if the archive goes away, they're back to where they started... no working URLs). Just wondering why for so long the archive has never been checked by tools when (imho) that only serves to break old releases sooner with respect to remote-fetch of a binary release file (e.g., pkg or dist, etc.). -- Devin _ The information contained in this message is proprietary and/or confidential.

In worst case, notify your system administrator.

What happens if you manually define those variables to the proper valies and try again, e. g. # setenv JAVA_HOME=/usr/local/where your JAVA stuff is # setenv JRE_HOME=/usr/local/where your runtime lives # bin/startup,sh Does this produce a different result? root@psumc:/usr/local/tomcat5.5 # su -c 'killall -9 java' That command doesn't make sense.

Re: A very 'trivial' question about /root
Hi Julian,
you played Devil's advocate well actually as I don't know which idea
would be more audacious, letting httpd access files from your root dir
or exporting /root via nfs. :)
Both of them sound more like a lab scenario than a real one.
I understand that launching a chmod 700 /root it's a matter of
something between 1 and 3 seconds. I do also understand that I had /root
closed for long time and never had the need to set permissions back
loose and this triggered my point.
Why is it that open? :)

This is the default permission for user directories, as root
is considered a user in this (special) case, and /root is its
home directory. The installer does not put anything secret

it to a more restricted access permission.

this is not desired, change to rwx/---/---, or rwx/r-x/---
if you want to allow (trusted) users of the wheel group
to read and execute stuff from that directory (maybe homemade
admin scripts in /root/bin that should not be public).
There are few things that touch /root content. System updating
might be one of them, but as it is typically run as root (and
even in SUM), restrictive permissions above the default are
no problem.

A diskless FreeBSD will use an NFS-mounted /root. See:
http://www.freebsd.org/doc/handbook/network-diskless.html
http://www.nber.org/sys-admin/FreeBSD-diskless.html
So it is more than a theoretical possibility. I would also add that
putting stricter permissions on perfectly public information may not
lead to improved security, if it leads to programs and daemons that
would otherwise run as nobody having to run with root priviledges.

is considered a user in this (special) case, and /root is its
home directory. The installer does not put anything secret
in there, but _you_ might, so there should be no issue changing
it to a more restricted access permission.
Hint: When a directory is r-x for other, then it will be
indexed by the locate periodic job, so users could use the
locate command (and also find) to look what's in there. If
this is not desired, change to rwx/---/---, or rwx/r-x/---
if you want to allow (trusted) users of the wheel group
to read and execute stuff from that directory (maybe homemade
admin scripts in /root/bin that should not be public).
There are few things that touch /root content. System updating
might be one of them, but as it is typically run as root (and
even in SUM), restrictive permissions above the default are
no problem.

Hi Julian,
you played Devil's advocate well actually as I don't know which idea

Both of them sound more like a lab scenario than a real one.
I understand that launching a chmod 700 /root it's a matter of
something between 1 and 3 seconds. I do also understand that I had /root
closed for long time and never had the need to set permissions back
loose and this triggered my point.
Why is it that open? :)
Here is a patch:

Before we might ask (via send-pr) for it to be commited,
we should various of us run
chmod 750 /root;chown root:wheel /root
give it a couple of months to see if problems.
I doubt there will be a problem with /root/.forward , as

The upgrade was a canary that told the user there is a problem. The idealized UNIX is standardized. According to Filesystem Hierarchy Standard (FHS), a UNIX standard: /root : Home directory for the root user (optional) Purpose The root account's home directory may be determined by developer or local preference, but this is the recommended default location. [17] [17] If the home directory of the root account is not stored on the root partition it will be necessary to make certain it will default to / if it can not be located. The above means that there has to be implied equivalency and consistency of permisssions between /root and / in order to ensure trouble-free operation of any process that may rely on any of them. That Linux case I referred to was a case about a system that relied on the above 0755 setup for /root dir, with an interesting twist of having it as a dummy account/dir for consistency, but having other accounts play the role of a superuser. Another example: some app (perhaps an installer) runs as non-root (e.g. Apache) user and needs to be able to read the root ssh public key from /root dir. There could be many such apps, accessing a front-end system, having to check for permission in /root dir for whatever they want to do, anywhere in sys admin, remote control, management, installation, etc areas.

mouse configuration question
I have a ps/2 mouse attached to a HP mini-tower running FreeBSD 8.3, with a stripped-down kernel (no loadable modules). I've apparently removed something necessary for standard mouse functionality, but I have no clue as to -what- is missing. Gory details: 1) '/dev/psm0' exists and +is+ the mouse, 2) 'moused' detects the mouse: psm0 sysmouse Intellimouse 3) 'moused -d' properly reports mouse activity -- button press/release and mouse motion. 4) 'vidcontrol -m on' reports inappropriate ioctl for device. 5) *NO* '/dev/sysmouse' device present. I'm building an ncurses-based app, and want to add mouse functionality. The ncurses mouse-related functions return 'total failure' status (value 0). I suspect that 5), above is the immediate issue, but can't find out 'who' is (ir-)responsible for creating that psuedo-device.

FreeBSD slice/partiton setup question
Hello: I have a question regarding FreeBSD slices/partitions. I have a disk with linux partitions with the following layout: /dev/sda1 / /dev/sda2 /home /dev/sda3 /usr/local /dev/sda5 swap /dev/sda6 /home/user1 /dev/sda7 /home/user2 etc. sda1, sda2, and sda3 are primary partitions, sda5 and above are logical partitions on an extended partition. I would like to have a similar setup with FreeBSD. The goal is that the / root, /home, /usr/local and /home/user1 etc. filesystems should be on independent slices/partitions so that I could mount them independently from linux. How can I do this in FreeBSD? Can I have slices with only one partition occupying the whole slice? Can I do something like the following: /dev/ad0s1a / /dev/ad0s2e /home /dev/ad0s3e /usr/local /dev/ad0s5b swap /dev/ad0s6e /home/user1 /dev/ad0s7e /home/user2 etc. where the partitions (a, e, b) occupy the whole slice where they reside on?

'slices' in FreeBSD, and most other 'real' unix systems, correspond to MSDOS/Windows 'partitions', on hardware that supports the MSDOS partitioning scheme.. Unix has its own layer of disk subdivision, referred to here as 'BSD partitioning' (to make clear it is not the same as Microsoft's 'fdisk' functionality, as well. In the 'classical' form this gives the (up to 8) 'letter-named' pieces that a disk may be carved into. You can use 'slices', giving filesystem names, after 'BSD partitioning', like '/dev/ad4s0a', or you can omit 'slice' creation, and do only a 'BSD partioning scheme, giving device names like /dev/ad4a. In the 'BSD partitioning' scheme, letter 'c' is reserved for the entire disk, but SHOULD NOT ever be used directly. One can create another 'BSD partition' (using the letter of ones choice) that also spans the entire disk. There is no requirement to have more than one 'usable' partition on the disk. Why bother with partitions if you're going to use the whole slice? Are you saying that one can use/mount a whole slice without adding partitions to it?

A full discussion gets 'messy'. there are lots of variations that complicate things -- including a single 'logical volume' with multiple physical disks (e.g. RAID), a single physical disk with multiple 'logical drives' on it (think 'fdisk' partitioning), *AND* the type of filesystem in use on the logical volume/drive. *ASSUMING* the 'Berkeley fast filesystem' (the traditional/classical system choice, also known as 'UFS'), a logical volume/drive must have a BSD 'volume label' on it, which allows subdividing that logical volume/drive into (up to) 8 letter-names parts. Each such 'part' holds a separate filesystem, and must be 'mounted', _individually_, before files on that filesystem can be acessed. The overall logic is similar for other filesystem types, however the mechanical details may be quite different. Could you please confirm if my understanding is correct, or explain a little bit more detailed what you meant? If you want a -single- filesystem to occupy an entire physical disk you can: a) use a 'dangerously dedicated' drive -- one with no 'fdisk' partitioning and only a BSD volume label, and create a single 'BSD partition' -- giving a device like '/dev/ad4h' b) creat a single 'fdisk' primary partition spanning the entire drive and put a BSD volume label on the primary partition, with only a single 'BSD partition' -- giving a device like '/dev/ad4s0h' c) do 'something similar' using a different partitioning scheme -- e.g. 'gpart' -- instead of 'bsdlabel'. d) do 'something similar' using a different type of filesystem -- e.g. 'ZFS' or 'EXT3' (beware: EXT3 is _not_ well-supported under FreeBSD, and there are 'good reasons' _not_ to use any of the EXT* filesystem types if one values the integrity of ones data in the event of 'unexpected' events. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr
Re: Re: FreeBSD slice/partiton setup question
You can simply newfs the device itself, without a volume label, slice, or partition. That's the normal thing to do with malloc devices, or additional disks. If the disk doesn't require a boot loader, isn't the root device, etc. that may be the best thing to do. Your caution about EXT* is spot-in - adequate tools exist for EXT2FS, but it's still problematic. - M ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Thanks, but I don't understand your answer. First I'd like to point you at the excellent documentation provided by FreeBSD: http://www.freebsd.org/doc/handbook/disks-adding.html http://www.freebsd.org/doc/en/books/handbook/geom-glabel.html http://www.freebsd.org/doc/handbook/bsdinstall-partitioning.html Also read Warren Block's article about the tools used in the old and new way of preparing a disk for use: http://www.wonkity.com/~wblock/docs/html/disksetup.html Regarding terminology, just if it hasn't been clear already: In UNIX terminology, a slice is what DOS and therefor Windows refers to as a DOS primary partition. It is designated a number. It can be subdivided in partitions which are designated a letter. A partition carries a file system, a slice carries partitions, and finally a device carries slices. (The slicing can also be omitted, this is called dedicated). Examples: ad0 = the 1st disk ad0s1 = the 1st slice ad0s1a = the 1st partition of the 1st slice ... ad0s1h = the 8th partition of the 1st slice And the dedicated approach: ad0a = the 1st partition directly created on the 1st disk The letters have a specific meaning: 'a' is a bootable partition. 'c' is the whole thing (being the whole slice or the whole disk), 'b' is reserved for a swap partition, and user-defined partitions go from 'd' to 'h'. As I mentioned, there is a new and an old way of partitioning. What I've discussed so far is called MBR partitioning, it's the old way. The new way, GPT partitioning, does not use the idea of slices and partitions anymore. Instead partitions are enumerated and created directly. Example: ad0 = the 1st disk ad0p1 = the 1st partition ... ad0p15 = the 15th partition Of course, different tools are involved here, as you can see in the documentation links provided above. I am puzzled a little bit. My understanding based on the FreeBSD handbook is that slices in FreeBSD are the partitions in linux. So far correct, with an exception: A slice does _not_ carry a file system, whereas in DOS terminology, reflected in Linux, the file system is created in a DOS-like manner. Example: /dev/sda1 = 1st disk 1st DOS partition (slice) _with_ file system /dev/ad0s1 = the same, but no file system here /dev/ad0s1a = 1st partition on that slice _with_ file system And that on one slice (linux partition) FreeBSD has (or can have?) several partitions. Correct. These are labeled as letters: a for root partition, b for swap, c for the whole slice, and e for a regular non-root partition. Correct as well. Are you saying that one can use/mount a whole slice without adding partitions to it? For example /dev/ada0s1 could be the root partition? No. You _need_ to create a partition, read: at least one partition. That partition can cover the whole slice (or device, as mentioned above), and it will be designated 'c', but that letter is omitted (I think since FreeBSD 5). Example: Let's assume you have created the /dev/ada0s1 slice already. Now you do: # newfs /dev/ada0s1 and you get a file system on the /dev/ada0s1c partition (which is created implicitely by newfs. You can now mount it: # mount -t ufs /dev/ada0s1 /mnt But remember: That is the 'c' partition! Similar approach for data disks (where you want to dedicate the whole disk to data use, not booting or anything else): # newfs /dev/da0 # mount -t ufs /dev/da0 /mnt Again, /dev/da0c is the device you're operating on (which carries the file system). Do you mean putting all partitions on one big slice? With traditional partitioning, you can only use up to 'h' partitions (with exceptions). If you need more than those 8, use GPT instead. If you _must_ use MBR partitioning, you can have up to 4 slices on a disk, giving you (with exceptions) 4 x 8 = 32 partitions for FreeBSD on one disk. I would like to be able to mount different partitions independently from other OS, eg. from linux. That can be problematic because Linux doesn't seem to fully support UFS file systems and BSD partitioning... If interoperability is your goal, then you should probably use exchange partitions with a file system that is better supported on FreeBSD (than using FreeBSD and hoping for greater-than-zero support on Linux). Check if Linux supports GPT properly. It's much easier to deal with GPT than with the

freebsd-update question
I had an 8.2 system that I wanted to take to 8.4. First I tried upgrade to 8.4, getting (in essence) can't do that. So I upgraded 8.2 which worked giving the end-of-life warning. But seemed work. I then did an upgrade to 8.3 with: freebsd-update -r 8.3-RELEASE upgrade The first part, downloading the diffs and inspecting the system seemed ok. The install seemed ok up to the point it wanted to edit files. It wanted to edit freebsd.submit.cf and sendmail.cf neither of which had local changes and then it started wanting to delete all the files in /etc. I aborted the process when it got to rc.conf. The message was something like, deleting file hosts.allow no longer in 8.3. Happily aborting the process left the system unchanged. Aside from, what could I have done wrong? My question is should we be able to trust freebsd-update on expired systems if it says a mirror exists and then sets about doing its thing?
