gnutls cannot connect to openbsd.org -- TLS 1.3 issue?
Hi, starting a couple of days ago, applications linked against gnutls can no longer connect to https://www.openbsd.org. Short output: $ gnutls-cli openbsd.org Processed 133 CA certificate(s). Resolving 'openbsd.org:443'... Connecting to '129.128.5.194:443'... *** Fatal error: An illegal parameter has been received. $ gnutls-cli -v gnutls-cli 3.6.10 More debug output can be produced with "gnutls-cli -d 999 openbsd.org". The interesting part is probably this: |<4>| HSK[0x1f80fb31a000]: CERTIFICATE VERIFY (15) was received. Length 516[516], frag offset 0, frag length: 516, sequence: 0 |<4>| HSK[0x1f80fb31a000]: Parsing certificate verify |<4>| HSK[0x1f80fb31a000]: verifying TLS 1.3 handshake data using RSA-SHA256 |<3>| ASSERT: signature.c[_gnutls_session_sign_algo_enabled]:364 |<4>| Signature algorithm RSA-SHA256 is not enabled |<3>| ASSERT: tls13-sig.c[_gnutls13_handshake_verify_data]:75 |<3>| ASSERT: tls13/certificate_verify.c[_gnutls13_recv_certificate_verify]:131 |<3>| ASSERT: handshake-tls13.c[_gnutls13_handshake_client]:144 |<13>| BUF[HSK]: Emptied buffer *** Fatal error: An illegal parameter has been received. Can be reproduced on OpenBSD 6.6-stable with gnutls from ports. (But it affects my Linux boxes, too.) It only fails with gnutls, so I first reported it there: https://gitlab.com/gnutls/gnutls/-/issues/984 However, Daiki Ueno said it looks like an issue with LibreSSL. Quoting in full: > This looks like an issue in the server side (LibreSSL). In TLS 1.3, > non-PSS RSA signature schemes have been removed, while the server > seems to sign the Certificate Verify message with RSA-SHA256, which is > not permitted. I'm not really an expert on TLS or cryptography, so no idea what's going on, which is why I'm reporting it on misc first. :-) Should this be reported to libre...@openbsd.org? Thanks in advance, Peter

Has been fixed in LibreSSL. Thank you!

Wireless interface iwn0 becomes detached
I am seeing a periodic and unexplained loss of wireless connection on my Thinkpad. According to ifconfig iwn0, after a period (roughly 30 mins) the DHCP-obtained IP is lost (status: no network, nwid ""), requiring a sh /etc/netstart iwn0 to get a new lease, or less frequently the interface simply disappears altogether. I've only noticed this using the latest snapshot, but I might have occured slightly before, I tend to update snapshots regularly. I'm sure it's happening on multiple machines but the dmesg below is from my x201. Any help gratefully received - happy to provide any further information.

Excessive fan - Thinkpad X1 (4th Gen)
Hi all, I have a recurring problem with OpenBSD on my Thinkpad X1 Carbon (4th Gen). When the machine wakes from suspend, there is (approximately) a 75% chance that the fan start and pretty much max out. Doesn't matter about CPU usage or temperature. Suspending (zzz) or closing the lid tends not to fix it - the fan will eventually stop but will start again on wake. Rebooting or hibernating is required. This has occured on this particular machine with various stable/release versions of OpenBSD and I'm currently running the latest snapshot (7.2-beta). I have used various Linux distros (Debian and Arch, mostly) on this machine in the past and this has never happened. I also have a Thinkpad X220 running the same versions historically without issue. I can't find much in the archives so I'm hoping someone might be able to offer something. Many thanks in advance. I include sysctl hw, sysctl hw.sensors and dmesg below: -- Best regards, Matthew syctl hw: hw.machine=amd64 hw.model=Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz hw.ncpu=4 hw.byteorder=1234 hw.pagesize=4096 hw.disknames=sd0:74bfeea5a5883a85,sd1:7da04eb499cd98e3 hw.diskcount=2 hw.sensors.cpu0.temp0=36.00 degC hw.sensors.cpu0.frequency0=32.00 Hz hw.sensors.cpu1.frequency0=33.00 Hz hw.sensors.acpibtn0.indicator0=On (lid open) hw.sensors.acpibat0.volt0=15.20 VDC (voltage) hw.sensors.acpibat0.volt1=16.26 VDC (current voltage) hw.sensors.acpibat0.power0=0.00 W (rate) hw.sensors.acpibat0.watthour0=38.50 Wh (last full capacity) hw.sensors.acpibat0.watthour1=1.93 Wh (warning capacity) hw.sensors.acpibat0.watthour2=0.20 Wh (low capacity) hw.sensors.acpibat0.watthour3=36.78 Wh (remaining capacity), OK hw.sensors.acpibat0.watthour4=52.06 Wh (design capacity) hw.sensors.acpibat0.raw0=0 (battery idle), OK hw.sensors.acpiac0.indicator0=On (power supply) hw.sensors.acpithinkpad0.fan0=6940 RPM hw.sensors.acpithinkpad0.indicator0=Off (port replicator), UNKNOWN hw.sensors.acpitz0.temp0=48.00 degC (zone temperature) hw.sensors.pchtemp0.temp0=35.50 degC hw.sensors.softraid0.drive0=online (sd1), OK hw.cpuspeed=2701 hw.setperf=100 hw.vendor=LENOVO hw.product=20FB002LUS hw.version=ThinkPad X1 Carbon 4th hw.physmem=17011974144 hw.usermem=15295393792 hw.ncpufound=4 hw.allowpowerdown=1 hw.perfpolicy=auto hw.smt=0 hw.ncpuonline=2 hw.power=1 sysctl hw.sensors: hw.sensors.cpu0.temp0=34.00 degC hw.sensors.cpu0.frequency0=325000.00 Hz hw.sensors.cpu1.frequency0=32.00 Hz hw.sensors.acpibtn0.indicator0=On (lid open) hw.sensors.acpibat0.volt0=15.20 VDC (voltage) hw.sensors.acpibat0.volt1=16.26 VDC (current voltage) hw.sensors.acpibat0.power0=0.00 W (rate) hw.sensors.acpibat0.watthour0=38.50 Wh (last full capacity) hw.sensors.acpibat0.watthour1=1.93 Wh (warning capacity) hw.sensors.acpibat0.watthour2=0.20 Wh (low capacity) hw.sensors.acpibat0.watthour3=36.78 Wh (remaining capacity), OK hw.sensors.acpibat0.watthour4=52.06 Wh (design capacity) hw.sensors.acpibat0.raw0=0 (battery idle), OK hw.sensors.acpiac0.indicator0=On (power supply) hw.sensors.acpithinkpad0.fan0=6932 RPM hw.sensors.acpithinkpad0.indicator0=Off (port replicator), UNKNOWN hw.sensors.acpitz0.temp0=48.00 degC (zone temperature) hw.sensors.pchtemp0.temp0=35.00 degC hw.sensors.softraid0.drive0=online (sd1), OK dmesg: OpenBSD 7.2-beta (GENERIC.MP) #640: Thu Jul 21 21:03:56 MDT 2022 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 17011974144 (16223MB) avail mem = 16479031296 (15715MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.8 @ 0xd7057000 (65 entries) bios0: vendor LENOVO version "N1FET75W (1.49 )" date 05/25/2021 bios0: LENOVO 20FB002LUS acpi0 at bios0: ACPI 5.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP TCPA SSDT UEFI SSDT SSDT ECDT HPET APIC MCFG SSDT SSDT DBGP DBG2 BOOT BATB SLIC SSDT SSDT MSDM DMAR ASF!
