If you're using femail with PHP inside a chroot jail, be aware that
PHP's built-in "mail" function uses popen(), which requires /bin/sh

Unfortunately pppd(8) upstream removed most OS support somewhere after the version we currently have so updating it is decidedly non-trivial (I think there might have been a few versions between ours, last real update in '98, and the last one with BSD support, but it's quite far from what upstream has now). You might think of looking at npppd(8) but it won't help, at least without further work: firstly it doesn't support client-side only server-side, and secondly its v6 support is limited to tunnel endpoints, it doesn't do ipv6 inside ppp. AFAIK the only ppp code in OpenBSD that supports IPv6 inside PPP is pppoe(4). (Pragmatically the easiest/cheapest way to handle l2tp-client is probably via a mikrotik box - setup is pretty straightforward, the main gotcha is you're likely to need the "/ip firewall mangle" equivalent of "scrub max-mss")

I am not entirely sure what to answer here because I don't know what
your question is, but maybe it helps to copy /bin/sh to ${CHROOT}/bin/sh

You need /bin/sh in the chroot for this to work.
"The exit status of the shell is 127 if the command file specified on
the command line could not be opened"
I've just added some more text to php's pkg-readme files about this

Does /bin/sh exist in the chroot? It’s needed by exec.

Using OpenBSD as an L2TP client with A ISP
I'm currently using OpenBSD with an Andrews & Arnold vDSL connection so I have a pppoe(4) interface, etc. and this works for IPv4 & IPv6. The problem is because of the rubbish rural Openreach infrastructure here in the UK I only get a stable 3.5 Mb/s, however another ISP (Voneus) has been installing fibre in the area and can offer a 100+ Mb/s connection, but it looks like their network is all sorts of CGNAT and they don't seem to offer IPv6 addresses. So I figured I'll just use the A L2TP relay service and use this new fast connection to tunnel all of my traffic between the two ISPs and maintain the IPv4 & IPv6 addesses that A have assigned to me on my vDSL connection. Has anyone done this with OpenBSD? I understand xl2tpd is in ports but does everything work through the tunnel, including IPv6? I saw mention about 8-9 years ago that the pppd(8) that xl2tpd uses doesn't do IPv6. Is that still the case? Thanks Matt
send help ( chroot php fpm refuse to exec/popen/procopen... on 7.0 )
}{ello,
I updated a device and use php fpm on openbsd 7.0
everything works fine after putting a resolv file in the chroot
but i can't send email from the chroot
I hope I didn't see something obvious.
to troubleshoot i drop the ksh inside the chroot
/var/www/usr/sbin/ksh:
StartEnd Type Open Ref GrpRef Name
0e4fc4d74000 0e4fc4e1a000 dlib 10 0
/var/www/usr/sbin/ksh
and wrote a stupid php
&1', $output, $retval);
exec ('/usr/sbin/ksh -c "echo a"', $output, $retval);
echo '';
echo "Returned with status $retval and output:\n";
echo '';
$rc = sprintf('%o', fileperms('/usr/sbin/sendmail'));
echo $rc;
echo '';
$rc = sprintf('ffoo: %o', fileperms('/usr/sbin/ffoo'));
echo $rc;
echo '';
print_r(array('o' => $output,'perm' => $rc, 'r' => $retval));
which output :
Returned with status 127 and output:
100555
ffoo: 100644
Array ( [o] => Array ( ) [perm] => ffoo: 100644 [r] => 127 )
which constantly returns 127 and no output ( also tried popen and
other methods , just use exec as a 'simpler' version.
Also used the ksh to double check ENV
chroot -u user /var/www /usr/sbin/ksh -c 'echo $USER'
and tested sendmail inside chroot with the chroot command.
After pondering the existence of the universe, i ktrace the php - fpm
process
ktrace -d -t cpxX -p 32152
and it's not really clear, i cannot see a vfork in there,
usr/local got the wxallowed

Internet service provider doesn't know how to internet. News at 11. They're not insecure (except by accident), they're incompetent. Just like everyone else. Also the company seems to be more ham-fisted in its approach to public relations than Zuckerbook. If your response to incompetence on the internet is to flee somewhere with competence* and thus ignore its hidden mistakes, then may I interest you in this fine bridge? Use whatever it is to your heart's content. Adverts are unhelpful. The question was "do you want to join our zoom conference" not "what should we use for internet conferencing".

futex(2) not working in inherited mmap'd anon memory
Hello,
When I do mmap(MAP_ANONYMOUS | MAP_SHARED) and then fork(), it seems
that futex(2) wakeups are not delivered between child and parent in
that memory. It does work as expected if I instead use
shmget(IPC_PRIVATE).
Below is a standalone test program. I tested it with the four OSes
mentioned, and the two shmem types depending on that #if, and all
worked as expected except the OpenBSD/mmap case, which hangs.
Is it a bug?

As your Solaris partition is first on the disk, I'm assuming that you installed OpenBSD afterwards. I'm also assuming that you didn't manually use the 'update' command from within OpenBSD fdisk to overwrite the MBR boot code, (just the boot code and not the partition data). The OpenBSD MBR code, I.E. what would be loaded from the first sector on the SSD at boot, is responsible for displaying the 'Using drive X, partition Y' message. If you are not seeing this, then the OpenBSD MBR code is not running. Of course, the Solaris MBR code should also correctly parse the partition table, see that partition 3 is flagged as active and pass control to the OpenBSD PBR contained in it, at which point you would see 'Loading', but that is not happening. If you boot into the OpenBSD bootloader from another device, such as a USB flash drive with the OpenBSD installation media on it, and manually type 'boot sd0a:/bsd', or whatever device the BIOS sees the SSD as, you should find that your newly installed system boots. If you want to write the OpenBSD MBR code to the SSD, you can do that using the 'update' command within fdisk. This will probably allow you to boot OpenBSD from the SSD. However, you will have overwritten the Solaris MBR, which may or may not cause you issues booting Solaris. You could back up the existing MBR first with a command such as: # dd if=/dev/sd0c of=$HOME/old_mbr bs=512 count=1 If you want to check that the OpenBSD MBR code is installed on the disk, the output of the following two commands should match: # dd if=/usr/mdec bs=446 count=1 | hexdump -C # dd if=/dev/sd0c bs=446 count=1 | hexdump -C

Now I'm having no issue with that kernel panic, perhaps I was just unlucky in when I chose to upgrade. What a relief. :) -- https://amissing.link
