(currently created it under /root/soc/socket ) Using MODULE_DEPEND Can I make the module dependent of file system? You can register a hook for the 'mountroot' EVENTHANDLER event which will fire after / is mounted. (You could compare rootvnode against NULL during module startup to determine if you should defer your work to the EVENTHANDLER vs doing it right away.) If you need to wait for all local filesystems to be mounted, then you will need to have some userland utility poke your module via a sysctl/ioctl/etc. after the filesystems are mounted (you could use a custom rc.d script for this). -- John Baldwin ___ 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

Sorry. A diff wouldn't have helped much, as every line had changed due to
my reformatting. Never mind, I'll work it out for myself by a process of
elimination - and I'll post the answer here just in case anyone else is
interested.

Kernel Panic - Unix socket communication in kernel module
Hello, I am writing a kernel module in which I am trying to connect to a UNIX socket (UNIX domain sockets use the file system as their address name space). Kernel module (loadable) acts as a client and User mode program acts as server, I have loaded the module using kldload and communication between user and kernel module works fine, when I try to load the kernel module from loader.conf - auto load the kernel module at boot up leads to kernel panic as the file system is not ready and kern_connect fails. How to notify kernel module that File system is ready? (any specific event flags) Is there any specific location for Unix domain socket files? (currently created it under /root/soc/socket ) Using MODULE_DEPEND Can I make the module dependent of file system?

I'm assuming you're talking about a fifo here (aka named pipe, and occasionally called UNIX socket) rather than the BSD network socket interface. IIRC since 4.3BSD fifos have been implemented using sockets internally anyway. Where to put it? I tend to go for /tmp but somewhere in /var might make more sense for something that's always supposed to be there. I don't know how to tell when the FS is ready but it will be when init runs, so you might like to try the sysctl variables. Knowing that init is always PID 1, the value of kern.lastpid should give a hint. There may be an official way of doing this properly. You could always load the module from rc.local instead.

Adding kernel config options?
Hi, I am wondering how one would add support for additional options in the kernel configuration files. I have found the config(8) program and the related files '/sys/conf/file' '/sys/conf/options', but am having trouble finding any documentation leading me beyond there. When I specify something like 'MY_OPTION opt_myopt.h' in the options file, how does this tie into my code? Any help or direction to where I can find further information would be greatly appreciated!

Why not use the module for this? For many years now, you
do not need a custom kernel if you want to use IPFW (which
_had_ to be compiled into the kernel in the past). Use
# kldload ipfw.ko
is it good idea to run this like this, would i have to do some settings,
as
i don't want to be locked out of the system?
Depends on your requirements. The kernel module is just the
firewall infrastructure, and the ipfw _binary_ will then
control it. So it's probably a good idea to check your firewall
settings (for example in /etc/ipfw.conf) to reflect _exactly_
what you intend (e. g., _not_ disabling SSH).
See man ipfw for details on the firewall configuration file.
The system brings several preconfigured profiles. You can find
them in /etc/defaults/rc.conf (the firewall_ settings group,
especially open according to /etc/rc.firewall's comment
header, or for example /etc/ipfw.conf, a file created on
your own). Do not use closed. :-)
Here's a short example, nothing magic:
-f flush
add allow tcp from any to any ftp in recv xl0
add allow tcp from any to any ssh in recv xl0
This is _one_ solution if you wanted to allow SSH and FTP
via the xl0 interface. Depending on what IPFW defaults to
(ALLOW or DENY), a different structure might apply. The
configuration line
add allow ip from any to any
will allow everything.
Dealing with kernel modules _might_ be a security issue if
you define it to be one. For example, if you raise the syetem
security level, you won't be able to load or unload kernel
modules. In such a situation, only the functionality present
in the kernel at boot time will be available. This if course
requires a custom kernel as explained.
Otherwise it's a good and comfortable idea to load IPFW as
a kernel module. It can then be configured in the same way
as a kernel-based firewall.
yes i would like to see if i can compile a kernel on an OVH box for
freebsd
i have tried, but there is always something that fails :-( so i wanted
the
use the one by OVH and modify it for my use.
For checking, you should first check if you can compile the
GENERIC kernel that's provided by the OS sources:
# cd /usr/src
# make buildkernel KERNCONF=GENERIC
If this works, you could install it and perform a reboot:
# make installkernel KERNCONF=GENERIC
# reboot
Then if you have derived your own kernel configuration file,
do the same with KERNCONF= and its name.
so i got the 9.1 sources and now in /usr/src/sys/amd64/conf i have a
GENERIC file, but this is too generic, besides i don't have access
to the
physical box.
This file is what the GENERIC kernel (distributed with the OS)
has been generated from. Use it as a template for your own
custom kernel.
well, there was no /usr/src when the system arrived from OVH i downloaded
this from freebsd ftp site. so i will need to update it to suit my system
and i was just looking for a shortcut.
If you have been using freebsd-update, it defaults to fetching
the OS sources (it's the src item in the Components list
of /etc/freebsd-update.conf. Your kernel and system sources
_might_ now be more current than the version you're running.
As I mentioned, it's neccessary to have world and kernel in
sync. The use of freebsd-update should have properly taken
care of this (e. g., updated world, GENERIC kernel, and the
sources for the whole thing to the current version).

custom kernel installation
hello,
i have a dedicated server from OVH and have updated freebsd to 9.1 and want
to enable IPFW in the kernel as this is not enabled.
the way i updated the system was to copy /boot/kernel.old to /boot/GENERIC
then followed ch25
http://www.freebsd.org/doc/en/books/handbook/updating-upgrading-freebsdupdate.htmlthis
went well and the system is up to date.
so i got the 9.1 sources and now in /usr/src/sys/amd64/conf i have a
GENERIC file, but this is too generic, besides i don't have access to the
physical box.
what will be the correct way to include the IPFW to existing /boot/kernel
is there a way to generate the GENERIC file from the existing loaded kernel?
this is what # dmesg brings up
http://pastebin.com/V8ZExNC8
do i need anything else?
any advice much appreciated

How to get kernel source code of free-BSD release 9.1

Then do: svn checkout svn://svn.freebsd.org/base/releng/9.1 /usr/src Once having checked out you can then issue a svn update /usr/src command to pull in security updates as they become available over time. There are also two US mirrors available such as: svn checkout svn://svn0.us-east.freebsd.org/base/releng/9.1 /usr/src svn checkout svn://svn0.us-west.freebsd.org/base/releng/9.1 /usr/src I have used the us-east one. There is also a project underway to add in to base an 'svnup', similar in scope to how csup replaced cvsup to make it easier in the future.

Re: Keeping FreeBSD with custom kernel up to date: freebsd-update no option?
Thank you, Polytropon. I have (as far as I can tell) successfully upgraded to 9.1-RELEASE-p2 now. For this I moved /usr/src (SVN) out of the way and followed the upgrade process described in 25.2.3.2 Performing the Upgrade in the Handbook [1]. on 17.4.13 22:55 Polytropon said the following: On Wed, 17 Apr 2013 22:37:06 +0200, andreas scherrer wrote: For some reason I was under the impression that /usr/src/sys is not being updated by freebsd-update if I remove kernel from the Components directive in freebsd-update.conf. But I might be wrong (I will check). According to the documentation, /usr/src (and therefor the /usr/src/sys subtree) is part of the src component, not of kernel, so it should be updated properly. OK. I will check if my /usr/src(/sys) ever changes now. I too think it should. Maybe related to this: how does freebsd-update know what sources/binaries to get when I don't use the -r switch? Does it rely on /usr/src/sys/conf/newvers.sh? That would still interest me (also see below). By following -RELEASE, freebsd-update will apply _that_ snapshot of the source tree and the prebuild world and kernel at the revision when X.Y-RELEASE-pZ has been verified, sloppily said. So it basically doesn't matter what sources you have on your machine (or even if you have any sources) as long as you're not going to compile anything. But because this is a requirement in your specific setting, freebsd-update will take care of that by having the src component on its list. So how would I follow -RELEASE. Or how does freebsd-update what I want to follow (see above)? I don't want to, so this is an academic question... And something else is bugging me: Is there a way I can contact someone (Tom Rhodes?) about the outdated freebsd-update documentation (concerning the custom kernel handling) in the Handbook (FreeBSD Update [2])? Colin Percival's email is in the man page, would that be the way to go? The Handbook states that Tom Rhodes wrote the freebsd-update section but does not reveal an email address...

Re: Keeping FreeBSD with custom kernel up to date: freebsd-update no option?
Hi Andreas and Polytropon,
In the case your are tracking -RELEASE branch, you can use freebsd-update
tool to apply binary security patches on your system and upgrade versions
(e.g. 9.0 to 9.1 or 9.x to 10.0 when available).
Freebsd-update tool apply binary updates to your system and GENERIC kernel.
Furthermore, this tool syncs sources (by default). So if you are using
custom kernel, you just have to rebuild and install your custom kernel.
It is recommended to not use SVN to update your system sources if you are
using freebsd-update tool to avoid troubles.
Regards,
Alexandre

Dear FreeBSD savvies
I am (still) struggling to understand how to keep my FreeBSD system up
to date (world/system, not ports). I want to track RELEASE (not a
development branch) and I want to receive security related updates. And
I want to run a custom kernel.
Without actually havint tested it, it seems that if you want
to use freebsd-update (binary updating), you should note this:
In /etc/freebsd-update.conf, you should have the line for what
to update as Components src world.
This should prevent overwriting of the kernel, but you need to
compile your kernel and install it. The component src will
make sure you have the proper kernel sources. I assume a custom
kernel configuration file in /usr/src/sys/{i386|amd64}/conf/
is _not_ being overwritten by freebsd-update.
Use the -r option of freebsd-update to specify the correct
release if required. It should follow -RELEASE-pN for the
currentl patchlevel N (which you intend to follow) normally.
From what I understand I cannot use freebsd-update in this case
because it will invariably either overwrite my custom kernel (if I have
Components kernel in the config file) or not update the kernel sources
in /usr/src/sys (when I do not have Components kernel in the config
file). See [1].
As far as I read from man freebsd-update.conf, the src component
will not exclude kernel sources; kernel refers to the kernel and
the modules as binary stuff.
This is the relevant text passage:
The components are ``src''
(source code), ``world'' (non-kernel binaries),
and ``kernel''; the sub-components are the indi-
vidual distribution sets generated as part of
the release process (e.g., ``src/base'',
``src/sys'', ``world/base'', ``world/catpages'',
``kernel/smp''). Note that prior to
FreeBSD 6.1, the ``kernel'' component was dis-
tributed as part of ``world/base''.
So src will include src/sys which is the kernel sources you
will need to build your custom kernel.
This leaves me with the only possibility to use SVN to update /usr/src,
right?
No, but it might be the more advanced alternative, and it should
work. Note that in _this_ case, you will also have to rebuild the
world, so kernel and world are in sync after an update. Refer to
the comment header of /usr/src/Makefile for the whole process that
has to be performed after updating (or see in the Handbook: the
section about updating by source).
I have a copy of the SVN sources (for the outdated RELEASE-9.0.0
but that's a different story), see below for svn info). As I
understand [2] I cannot mix freebsd-update and SVN, right?
It could cause trouble. Deciding for _one_ way should be better.
So I can run svn update in /usr/src whenever I like. But what then? Do
I need to rebuild the world and my custom kernel every time I run svn
update (and there are some updates)?
Yes, or better: As soon as it is required. This depends on _what_
has been part of the update. For example, kernel updates _can_
require updates of userland programs or libraries, but it's also
possible that it's not the case. To be sure, rebuild.
I'm on a low powered consumer
device and it takes considerable amount of time to build the world and
kernel (plus I still don't feel comfortable doing such tasks remotely).
In this case, use freebsd-update as explained at the beginning of
my message: Update components world and src, leave out kernel,
the rebuild the kernel by source and install it. Then reboot.
Is this really the way to do it or am I missing something?
There are _several_ ways to do it. :-)
There are quite some posts, websites and threads out there (see [3] or
[4] for example) about this topic but (surprisingly?) I could not (yet)
find a conclusive answer.
This is because the answer depends on what you actually want to do
(follow RELEASE, STABLE, CURRENT), and how you want to do it (binary,
by source).

Bad kernel with make -j?
Everyone: I've just had to resurrect a machine which apparently failed because the kernel was built with the make -j option. As reported in the make(1) man page, the purpose of the -j option is to let the make program build multiple portions of a program concurrently on a machine with multiple CPUs. The idea is to make use of SMP to speed up the build process. Unfortunately, after updating a FreeBSD 9.0 system with freebsd-update (and seeing some changes that would affect the custom kernel the machine was running), I rebuilt the kernel using the -j5 option. (The machine has 2 cores and 4 threads, but threads block due to I/O as well as memory access. So, when it works properly, -j5 is the fastest option.) The result was a kernel in which some compiled-in modules -- in particular, netgraph nodes -- weren't accessible. mpd5 began spewing odd messages, and VPN connections would not come up. I'd built the kernel with the NO_MODULES option, so the modules that were missing couldn't be loaded dynamically. Rebuilding the kernel using a single-threaded make solved the problem. Have others seen the same symptoms? I'd like to be able to do fast, multithreaded kernel builds, but will obviously have to avoid it if the resulting kernels are corrupted. --Brett Glass ___ 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

In /etc/freebsd-update.conf, you should have the line for what
to update as Components src world.
That's what I thought (and currently have).
This should prevent overwriting of the kernel, but you need to
compile your kernel and install it. The component src will
make sure you have the proper kernel sources. I assume a custom
kernel configuration file in /usr/src/sys/{i386|amd64}/conf/
is _not_ being overwritten by freebsd-update.
A custom kernel configuration file is *not* overwritten by
freebsd-update, I can confirm this. Of course I will have to compile and
install my custom kernel manually.
For some reason I was under the impression that /usr/src/sys is not
being updated by freebsd-update if I remove kernel from the
Components directive in freebsd-update.conf. But I might be wrong (I
will check).
Maybe related to this: how does freebsd-update know what
sources/binaries to get when I don't use the -r switch? Does it rely
on /usr/src/sys/conf/newvers.sh?
Could it be that I never saw a change to my kernel sources
(/usr/src/sys) because freebsd-update was tracking some static sources?
[snip]
I'm on a low powered consumer
device and it takes considerable amount of time to build the world and
kernel (plus I still don't feel comfortable doing such tasks remotely).
In this case, use freebsd-update as explained at the beginning of
my message: Update components world and src, leave out kernel,
the rebuild the kernel by source and install it. Then reboot.
That's what I am planning to do. Let's see.
As I currently have a checkout from SVN in /urs/src I need to get rid of
this. Can I just copy (read: move) back my previous /usr/src directory
and continue to use freebsd-update? I think this should work, right? I
am just not sure if freebsd-update still knows what sources/binaries
to track (see my previous comment about how freebsd-update knows what
source to use).

Re: Bad kernel with make -j?
on 17.4.13 21:18 Brett Glass said the following: I've just had to resurrect a machine which apparently failed because the kernel was built with the make -j option. [snip] The result was a kernel in which some compiled-in modules -- in particular, netgraph nodes -- weren't accessible. mpd5 began spewing odd messages, and VPN connections would not come up. I'd built the kernel with the NO_MODULES option, so the modules that were missing couldn't be loaded dynamically. Rebuilding the kernel using a single-threaded make solved the problem. I am not very experienced but I stumbled over the following note in /usr/src/UPDATING before: Avoid using make -j when upgrading. While generally safe, there are sometimes problems using -j to upgrade. If your upgrade fails with -j, please try again without -j. From time to time in the past there have been problems using -j with buildworld and/or installworld. This is especially true when upgrading between distant versions (eg one that cross a major release boundary or several minor releases, or when several months have passed on the -current branch). Maybe that's a hint? --Brett Glass ___ 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 Cheers andreas ___ 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

For example, if only a userland program has received a security update, and the kernel was kept the same, no change would be done in /usr/src/sys. In this case, the kernel version output (as seen by the uname program) would not have changed. As I currently have a checkout from SVN in /urs/src I need to get rid of this. Can I just copy (read: move) back my previous /usr/src directory and continue to use freebsd-update? You should not switch between both methods, it may cause problems. The simplest way would be to # mv /usr/src /usr/src.svn and let freebsd-update populate the sources with the required version. Note that it will install the world your (custom) kernel will finally have to match, and so it should make sure you have the correct revision of the sources to avoid a version conflict. However, it's basically not a problem to use SVN to track -RELEASE, but in this case, you should recompile world and kernel from that sources, instead of relying on freebsd-update for a binary update of the world only. But as you said you're only interested in a custom kernel (which _requires_ building from source), you can safely leave everything else to freebsd-update and don't use SVN. (It would be a totally different thing if you would track -STABLE or -CURRENT which is not possible with freebsd-update, and which would _force_ you to build everything from source.) By following -RELEASE, freebsd-update will apply _that_ snapshot of the source tree and the prebuild world and kernel at the revision when X.Y-RELEASE-pZ has been verified, sloppily said. So it basically doesn't matter what sources you have on your machine (or even if you have any sources) as long as you're not going to compile anything. But because this is a requirement in your specific setting, freebsd-update will take care of that by having the src component on its list. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ 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

This should prevent overwriting of the kernel, but you need to

is _not_ being overwritten by freebsd-update.
Use the -r option of freebsd-update to specify the correct
release if required. It should follow -RELEASE-pN for the
currentl patchlevel N (which you intend to follow) normally.
From what I understand I cannot use freebsd-update in this case
because it will invariably either overwrite my custom kernel (if I have
Components kernel in the config file) or not update the kernel sources
in /usr/src/sys (when I do not have Components kernel in the config
file). See [1].
As far as I read from man freebsd-update.conf, the src component
will not exclude kernel sources; kernel refers to the kernel and
the modules as binary stuff.
This is the relevant text passage:
The components are ``src''
(source code), ``world'' (non-kernel binaries),
and ``kernel''; the sub-components are the indi-
vidual distribution sets generated as part of
the release process (e.g., ``src/base'',
``src/sys'', ``world/base'', ``world/catpages'',
``kernel/smp''). Note that prior to
FreeBSD 6.1, the ``kernel'' component was dis-
tributed as part of ``world/base''.
So src will include src/sys which is the kernel sources you
will need to build your custom kernel.
This leaves me with the only possibility to use SVN to update /usr/src,
right?
No, but it might be the more advanced alternative, and it should
work. Note that in _this_ case, you will also have to rebuild the
world, so kernel and world are in sync after an update. Refer to
the comment header of /usr/src/Makefile for the whole process that
has to be performed after updating (or see in the Handbook: the
section about updating by source).
I have a copy of the SVN sources (for the outdated RELEASE-9.0.0
but that's a different story), see below for svn info). As I
understand [2] I cannot mix freebsd-update and SVN, right?
It could cause trouble. Deciding for _one_ way should be better.
So I can run svn update in /usr/src whenever I like. But what then? Do
I need to rebuild the world and my custom kernel every time I run svn
update (and there are some updates)?
Yes, or better: As soon as it is required. This depends on _what_
has been part of the update. For example, kernel updates _can_
require updates of userland programs or libraries, but it's also
possible that it's not the case. To be sure, rebuild.
I'm on a low powered consumer
device and it takes considerable amount of time to build the world and
kernel (plus I still don't feel comfortable doing such tasks remotely).
In this case, use freebsd-update as explained at the beginning of
my message: Update components world and src, leave out kernel,
the rebuild the kernel by source and install it. Then reboot.
Is this really the way to do it or am I missing something?
There are _several_ ways to do it. :-)
There are quite some posts, websites and threads out there (see [3] or
[4] for example) about this topic but (surprisingly?) I could not (yet)
find a conclusive answer.
This is because the answer depends on what you actually want to do
(follow RELEASE, STABLE, CURRENT), and how you want to do it (binary,
by source).

9-STABLE doesn't boot: can't load 'kernel'
After installing 9.1-RELEASE amd64 on a system, it boots up fine. If I then build and install a new 9-STABLE kernel world, reboots die in the loader with: can't load 'kernel' This is a pretty straightforward system, one drive, not large (128GB SSD). GPT partitioned, gptboot boot code. One UFS root partition to boot from, a swap partition and, the rest for ZFS. (At first I tried to do this system with root-on-ZFS but that also failed, adding unable to load zpool by guid or similar before the can't load 'kernel' message.) Once this happens, the disk is unbootable. I can start from the install CD and access the disk just fine, but even if I move kernel.old back to kernel, it doesn't boot anymore. Likewise, it doesn't matter if I overwrite the boot code with gptboot pmbr from the install CD or the new ones from /boot after installworld.

Re: 9-STABLE doesn't boot: can't load 'kernel'
I can't recall, does the cd come with the btx loader? Is it able to see the hard drive partitions and boot that way? Did you put anything in loader.conf? I'm guessing that if you're getting to /boot/loader but not any further, it's something wrong with the conf file. If you're booting UFS, you might be safe just deleting/renaming the file.

You cannot yourself change the license on code you do not hold the copyright on. Period. If you make changes and redistribute them then add your copyright notice with license to the files. Do not remove the existing copyright notice(s) and license(s). You hold the copyright for stuff you wrote, but the original copyright stays for the parts that did not come from you. Parts means any fraction of a file from the whole file down to small amounts. You are allowed to add restrictions (unless the existing license says you can't), but you are not allowed to loosen the existing restrictions (unless the existing license says you can). Also, it follows from the copyright that your license only applies to the parts copyrighted by you. The existing licenses are similar in that they apply only to their parts of the file. All licenses must be followed when the file is treated (copied, used, etc) as a whole. Make sure your license isn't incompatible with the license that applies to other parts of the same file. If that happens then how it will turn out in court is anyone's guess. The file may not be usable by the public, or the incompatible license terms added by you may be struck down, or a judge could cook up something else. It can't be predicted in advance so just don't even go there. Giving credit where it is due is an important social convention, and I'm glad to see that you aren't planning on doing anything unethical like breaking it. But copyright comes from the law and thus must be obeyed even if you wanted to break purely social conventions. Read up on copyright, and when you do pay close attention to the reliability of the source. The issue has become very political in the past 15 years or so. Don't be badly advised by someone who has their own agenda. Most people, to varying degrees, have their own agenda. Finally, if money is at stake (directly or indirectly) I strongly advise talking to a copyright lawyer in particular. That's just general advice. Taking advice from random people online is not a good idea if any money is involved, but I'd give the same advice to my best friend. The general rule applies here as it does elsewhere: You get what you pay for. Does one have to file legal paper work with the government to be issued a copyright on software?

You cannot yourself change the license on code you do not hold the copyright on. Period. If you make changes and redistribute them then add your copyright notice with license to the files. Do not remove the existing copyright notice(s) and license(s). You hold the copyright for stuff you wrote, but the original copyright stays for the parts that did not come from you. Parts means any fraction of a file from the whole file down to small amounts. You are allowed to add restrictions (unless the existing license says you can't), but you are not allowed to loosen the existing restrictions (unless the existing license says you can). Also, it follows from the copyright that your license only applies to the parts copyrighted by you. The existing licenses are similar in that they apply only to their parts of the file. All licenses must be followed when the file is treated (copied, used, etc) as a whole. Make sure your license isn't incompatible with the license that applies to other parts of the same file. If that happens then how it will turn out in court is anyone's guess. The file may not be usable by the public, or the incompatible license terms added by you may be struck down, or a judge could cook up something else. It can't be predicted in advance so just don't even go there. Giving credit where it is due is an important social convention, and I'm glad to see that you aren't planning on doing anything unethical like breaking it. But copyright comes from the law and thus must be obeyed even if you wanted to break purely social conventions. Read up on copyright, and when you do pay close attention to the reliability of the source. The issue has become very political in the past 15 years or so. Don't be badly advised by someone who has their own agenda. Most people, to varying degrees, have their own agenda. Finally, if money is at stake (directly or indirectly) I strongly advise talking to a copyright lawyer in particular. That's just general advice. Taking advice from random people online is not a good idea if any money is involved, but I'd give the same advice to my best friend. The general rule applies here as it does elsewhere: You get what you pay for. Does one have to file legal paper work with the government to be issued a copyright on software? No, copyrights are more like artists signing their work -- in a standardized way -- but every bit as legally binding. They are first come priority in the court of law and if-ever disputed, often require correlative evidentiary proof to show true ownership (a notarized copy of the work mailed to yourself kept in an unopened envelope perhaps). Does any software not having a copyright statement or any license comments included in the source mean that it's public domain? Be careful here. The answer to your question is NO. If a work lacks a license in the source, it may be on the website. If you can't find a license, you must always contact the author(s) before forking something. If you can neither find the license nor the contact info, it's always best to assume it is not for reuse. Even the, if you used code that was from an unknown origin with no license and no author, you should indicate as such in the header of such source files. Essentially what it boils down to, is that in the court of law (if someone indicts or brings a civil suit) you may have to account for the origin of every line -- so that's why: 1. If a file has an inline license (beerware, gpl, bsd, apple, or even one you make up all your own), it must stay there to mark the origins 2. If a file is lacking an inline license, it is often because the license is too long or unwieldy to embed and it is in a COPYING file distributed with the source code OR in a terms of agreement on the website (in which case you should download it and place

Obtaining copyright is implicit (by creating stuff), giving up copyright is an explicit act. Copyright information and licensing statements don't have to be neccessarily included in the file in question, they could also be in a file coming with the file in question, such as a LICENSE text file or AUTHORS, or in a manpage refering to a specific program (even though it's quite common to place that information at least as comments in source files). No not finding this information in the source and therefor _assuming_ there is no copyright holder or no license (and therefor all rights granted) is wrong. An exception might actually be code snippets below the 'triviality threshold' (as you mentioned is at least known in Germany) which have been published anonymously. In this case, neither an author or a license can be found, and in the absence of _both_, the assumption of the snippet being in the public domain would at least be undertandable. If it is _valid_ under all circumstances and in all juristictions, that's a totally different questions, to be answered by two lawyers with three opinions. :-) While German law has something like a triviality threshold which may well apply to very small code snippets, i'd say no included license by default means all rights reserved. As for licenses (copyright aside), this may very well be. If no rights are explicitely granted (even the do whatever you want right), it could be invalid to simply _assume_ such a right.

Freebsd 9.1 kernel compile with Physical Address Extension
Hi, I have been trying to compile the 9.1 kernel for an older system which has PAE support, unfortunately because -Werror is enabled, I cannot complete the compile (see warnings below). I am running a fresh install of FreeBSD 9.1-RELEASE. I can successfully compile the kernel without PAE. Kernel config: http://pastebin.com/5mzQagKM cc1: warnings being treated as errors /usr/src/sys/cam/ctl/ctl_frontend_cam_sim.c: In function 'cfcs_datamove': /usr/src/sys/cam/ctl/ctl_frontend_cam_sim.c:423: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] /usr/src/sys/cam/ctl/ctl_frontend_cam_sim.c:449: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] *** [ctl_frontend_cam_sim.o] Error code 1 I am new to the mailing lists (and mailing lists in general) so let me know if you need any more information.
