Poor browser performance in OpenBSD
Hello. I'm using Firefox and Chromium (from packages) to browse the internet on OpenBSD 6.3 (amd64). The problem is that their performance in OpenBSD is very poor compared to other OSes. Everything I found regarding boosting their performance: 1) Changing some values in login.conf for login group staff and adding myself to that login class: staff:\ :datasize-cur=4096M:\ :datasize-max=infinity:\ :openfiles-cur=1024:\ :stacksize-cur=64M:\ :maxproc-max=512:\ :maxproc-cur=512:\ :ignorenologin:\ :requirehome@:\ :tc=default: 2) sysctl kern.shminfo.shmall=268435456 All of this was taken from here: http://openbsd-archive.7691.n7.nabble.com/Coddling-bloated-web-browsers-etc-or-how-far-does-kern-shminfo-shmall-usefully-go-td244155.html These changes to the system don't seem to have any effect. Loading pages is slow, watching online video is possible but the responsiveness of the browser becomes awful. Do I need additional settings to fix this? dmesg: OpenBSD 6.3-current (GENERIC.MP) #13: Thu Jun 14 17:29:44 MDT 2018 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8442433536 (8051MB) avail mem = 8108933120 (7733MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xe9374 (57 entries) bios0: vendor Hewlett-Packard version "K01 v02.57" date 11/16/2012 bios0: Hewlett-Packard HP Compaq Pro 6300 All-in-One PC acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP APIC MCFG HPET SSDT SSDT SLIC SSDT SSDT TCPA ASF!

iked support for IKEv2 Message Fragmentation (RFC 7383)
Hello misc@, My IKEv2 sessions are occasionally down due to transit networks dropping UDP fragments for one reason or another[1]. It happens frequently enough that I am considering implementing support for RFC 7383 in iked. Before I dig in, I feel that I should ask if anyone has already started on such work. If not, perhaps someone that is familiar with the code could suggest an approach at a high level? Thanks for any advice, -TimS [1] Whenver I've asked, the reason is usually something about DDoS prevention. -- Tim Stewart --- Mail: t...@stoo.org Matrix: @tim:stoo.org

firefox crashes when password field is focused
Title pretty much says it. Whenever I click on a password field on a website firefox crashes. This is on current w/ newest firefox and is reproducible on every password field on every site I tried (although usernames work fine) and is reproducible with all combinations of settings including default. It has persisted for the last few days. dmesg and gdb output is below. If you have more things to test or need more information I can probably provide it.

Re: OpenBSD in qemu freezes randomly
Hi Stuart, I had a similar issue on Proxmox /KVM the issue doesnt affect linux guests / windows guests on a KVM Box It doesnt affect OpenBSD running on Older versions of KVM / Linux Kernel (4.x) it would appear to be a compatibility issue between an openBSD guest and the virtual hardware (virtual timers) as presented by newer KVM boxes http://openbsd-archive.7691.n7.nabble.com/Performance-issues-as-KVM-guest-td334612.html as Stuart Henderson pointed out kernel pre-emption timer disabling worked for us and would probably help you... that said the Kernel Patch as mentioned by Kaptaniks sounds interesting and may be a more permanent fix (on my to do list to try ...)

20% package loss on CARP after upgrade to 6.3
Hey everybody, I'm experiencing problems with CARP after upgrading to 6.3, it was working fine between my two servers in 6.2 but after upgrading (first backup and then master) I have a ping package loss on about 20%. It seem like the backup server tries to take the master, cause it's the only one changing the states. When it changes state the symptoms is: one package is dropped (ping), and it switches back to backup. I haven't changed anything, carp-config or PF, except the upgrade to 6.3. It works if i shutdown the master, then Backup takes over fine and gives back to master when it gets up, but when it's just running in backup, it switches back and fourth. I have tried tcpdumping and looking at my pfsync0 but I can't find the problem. I have tried to write my CARP settings again in hostname.carp* on both servers, check if pfsync0 is on the same interface and IP-range on both servers, checked my PF and everything, but can't find the problem... It does it across all 6 CARP's, so it looks like it's missing a hardbeat or something once in a while. I also tried switching from multicast to unicast, in case my ISP (running Juniper equipment) have activated something on the WAN side, but it didn't change my experience - but since it also happens on my LAN I didn't really expect this to be the problem. # Server 1 My /etc/hostname.* for CARP's and pfsync + host adaptor: https://pastebin.com/vrtuPqnQ My /etc/pf.conf: https://pastebin.com/yhVkG4x4 # Server 2 My /etc/hostname.* for CARP's and pfsync + host adaptor: https://pastebin.com/a7fuM923 My /etc/pf.conf: https://pastebin.com/xNr1TtZ7 Any help or pointers would be fantastic. I have struggled with this for a week now and I'm running out of idears - the only solution I have right now is turning off the backup server. $ uname -a OpenBSD BSD-firewall01.static.semarkit.net 6.3 GENERIC.MP#107 amd64 Both servers is running on a KVM host running Debian Stretch with ZFS-for- Linux and they haven't been touched either since it got installed, neither before, under or after the problems started. em0 is passed through the host and running all the VLAN and CARP things, while em1 (pfsync0) is a crossed connection between the two host servers not connected to the outside world or switch. If you need any other information on anything in the setup, please feel free to ask, I'm really annoyed by this, since it has worked and now it don't, and I can't figure out why or what I have missed. The only thing I haven't tried yet is to install a couple of new server and reproduce the problem. Sorry for a really long post! -- Med Venlig Hilsen / Best Regards Henrik Dige Semark

I had a problem like this as well, this was about the time I was battling rl0 issues on an old industrial PC, so thought it might've been something else causing the issues. With the exception of the border router, all my other OpenBSD instances are virtual machines. Updating the VMs to 6.3 proved to be quite an adventure as the kernel would randomly freeze up. `virt-manager` would show the virtual processor spinning at 100% CPU, `top` on the host would show qemu-system-x86_64 consuming 100% CPU. One spot it'd freeze up (in the installer) is creating /dev nodes, and sometimes when re-linking the kernel. Very rarely, it will freeze up on the production install. None of the Linux guests are affected, it's just OpenBSD. I've seen it in 6.1, 6.2 and 6.3. (They were 6.1 VMs; did the update to 6.2 then to 6.3.) Due to resets during install, one of my routers complains (the "insecurity" report from cron) about permissions and ownership on /dev nodes as a result. It's on my TO-DO list to clean this up. https://www.mail-archive.com/misc@openbsd.org/msg161846.html was posted as a response to me trying to find a work-around until such time as I could investigate it further. If it happens again, I wonder if it's worth breaking into the QEMU monitor and seeing where the CPU registers are pointed and to inspect the RAM on the VM to figure out where in the kernel OpenBSD is spinning? (Although trying to figure out where in the kernel a particular hex dump of machine code came from will be "fun".)

OpenBSD in qemu freezes randomly
Hi, i have searched the list archive and found some similar reports but none of them found a solution for the problem. (at least not the threads i have found) I run some OpenBSD 6.3 instances in a virtual environment. The host is some unknown Linux distribution with qemu on it. After the data center updated there kernels and also qemu my virtual OpenBSD instances startet to freeze randomly but almost always during login. They freeze up so hard that i cannot drop into a debugger or get any output whatsoever. There is not even a core dump, nothing. Just for testing purposes i installed a 6.2 as well and did syspatch on it just to see if the error happens there as well and it does. I have added a dmesg on the bottom of the email. I talked to the people at the datacenter and they confirmed that they did a Linux kernel update at the same time as the problems started. They send me a link to this bug report here from Arch. They say they don't use Arch, but the problem described here is exactly what i experienced as well: https://bugs.archlinux.org/task/55231 In this ticket someone commented the following: It looks like linux-4.12.8-1 is built with GCC: (GNU) 7.1.1 20170630, whereas linux-4.12.8-2 with GCC: (GNU) 7.2.0 (which apparently is still in testing) Could there be some sort of new optimization in GCC 7.2.0 that causes my OpenBSD instance to crash? I have looked around the misc@, tech@ archives and also on reddit. A lot of people seam to have this problem with there OpenBSD crashing after this quemu update. Is there something i could try in order to stabilize the servers? All servers are updated via syspatch and there is only one package installed on them: vim. The rest is as shipped in the sets.

Re: New laptop recommendations
I use 6.3 on my T450S. Works great. Also have installed easily on the Dell E7240 and E7440. I prefer the Thinkpad but the Dell is solid also. You can probably get one of each for under $1000. Likely you will want to replace the battery either way but all of these machines are available used quite reasonably and new batteries are available for all.

Definitely second the ThinkPad recommendations.

Re: rtadvd bug ?
Le 17/06/2018 à 22:57, Sebastian Benoit a écrit :
you have to do check
if (rtm->rtm_flags & RTF_CONNECTED)
The priority of a connected route depends on the interface priority,
see ifconfig(8) on the priority option and wifi and carp interfaces have a

for the type of the route.

Hello,
The patch indeed prevent including ospf6d-learned route to be advertised
by rtadvd, as priority is 32 (RTP_OSPF).
I had to add a check on RTM_DELETE: case too, as ospf6d add (an remove)
routes on itself, see this:
fremen# route -n show -inet6|grep ac42
2a01:e35:8aea:ac42::/642a01:e35:8aea:ac42:200:24ff:fed1:420d
UCn12 - 4 em1
2a01:e35:8aea:ac42::/64link#2 UC
00 -32 em1
2a01:e35:8aea:ac42:200:24ff:fed1:420d is em1 address.
without checking priority on RTM_DELETE, stopping ospf6d removes all
prefixes ...
checking rtm_flags & RTF_CONNECTED works too, as Sebastien said.
dhcpv6-pd works regardless of the check (I run it on this router).
