ppppoe octeon kernel panic .6.6
Hi,
The mail from Holger Glaess seems to be missing a backtrace. I got one, but
I have very little time today and tomorrow to debug anything, I have put a
temporary replacement for the octeon pppoe router at my premises for the time
being.
Also, I tried poking around in sppp_auth_send() in /sys/net/if_spppsubr.c but
to no avail. The fault lies in bcopy() in that function. In the backtrace
it shows up as smallcpy(). When pppoe0 is disabled the kernel doesn't panic.
My bt follows with dmesg from my machine that was upgraded to 6.6.
After that Holger Glaess's mail which I had to fish out of my trash as I
had accidentally deleted it.

Not Xauthority per say, but reaching back to he caller's home directory allowing arbitrary files to be loaded and potentially executed as another user in a way not intended potentially leading to privilege escalation. Instead of setenving HOME and PATH I suggest you change the command to xterm -e doas pftop & or if your needs are covered xterm -e doas systat states & martijn@
After sysupgrade to 6.6 from 6.5, xfce display alternates between desktop and app
So I read through the two threads below which both point to the third link about xfwm4 composter. I am not sure if I have the exact same issue. While you could say my screen flickers - what it really does is randomly (to my eyes) show the desktop and then show any open apps I might have while hiding the title bar. If I click around or move the cursor around the title bar area it will alternate between the desktop and apps. If I leave the display alone every 1-4 seconds the display will flip. Via .xsessions turning the composter off or setting it to xpresent freezes the screen to show just the desktop. Clicking doesn't change the view or bring forward or hide any apps. However I found if I switch to a non XFCE tty and back the display will change to what I tried to click on. Any thoughts on what I might experiment with or investigate further? Thanks.

acme-client issue with domain w/ alternative name
Today acme-client renewed all but 2 of my domains; the two that have
"alternative names"
in the certificates. I cannot get it to renew those two. This is on amd64 on

My acme-config.conf is the latest example version, with the v2 URLs and with
example.com replaced by

wireguard and nat redirection issue
Hi, I have setup a Wireguard server on my home network and I can get my phone
to connect to the WG server over the Internet but from my local lan I am having
nat issues that I have been unable to resolve and wondered if someone could
help ?
After reading the NAT man pages I moved my WireGuard server onto it's own
network / vlan as I though that by doing that I would be able to get a combo of
nat / rdr rules to redirect the traffic from my default lan onto the wireguard
vlan but this just doesn't seem to be working. I can see the WG traffic coming
in on the lan interface but it just keeps heading for public IP address.

OpenBSD and doas xterm pftop
I was surprised that after upgrading to 6.6 that doas xterm pftop & fails with: Warning: This program is an suid-root program or is being run by the root user. The full text of the error or warning message cannot be safely formatted in this environment. You may get a more descriptive message by running the program as a non-root user or by removing the suid bit on the executable. xterm: Xt error: Can't open display: %s This is the result of the change in the behavior of doas. Quoting from the upgrade manual doas(1). The environment variable handling in doas(1) has been changed. In particular HOME and PATH are now reset to the target user. I assume that the problem arises because .Xauthority cannot be found Pass HOME and PATH in doas.conf allows the old behavior.
Re: Two part question on httpd
Thank you for these links. These related projects are what inspired me to head down this path, however they seem focused on using sqlite, which I do not wish to use. I currently use sqlite in other software and run into both performance and scalability issues. Hence my interest in mysql based dbs.

Most compiled languages don't need w+x across the board (though might do for certain software). afaik GHC-compiled things do require w+x mappings. > Additionally, if c/c++ are indeed the few compiled languages which do > not violate this option, where might one find a library to write a > C program which interacts with mysql/mariadb?

Two part question on httpd
Hello, I am experimenting with httpd's cgi options. Why when I run binaries written in C from /var/www/cgi-bin, it's allowed but if I use other compiled languages (ex: Haskell) I need to adjust the wxallowed options for where /var/www/cgi-bin is mounted? Is this due to where it says: "...The base system has no W^X-violating programs, but the ports tree contains quite a few" in the following? https://www.openbsd.org/faq/upgrade60.html Additionally, if c/c++ are indeed the few compiled languages which do not violate this option, where might one find a library to write a C program which interacts with mysql/mariadb? So far, I have only found mysql++ and would prefer not to use c++ unless there are no other options. My goal is to write a simple REST api which interacts with mysql, and serves via httpd. I already have one written in PHP, but would like to port it to a compiled language. Regards, -J
