I updated my Loongson netbook from OpenBSD 6.6 on the week-end to 6.9… the process I followed: 1. download bsd.rd for OpenBSD 6.7 from ftp.openbsd.org 2. boot it, do an "Upgrade" 3. once booted into OpenBSD 6.7, do `sysupgrade` to get to 6.8 4. once booted into OpenBSD 6.8, do `sysupgrade` to get to 6.9 Note that in my case, I had some fiddling inside PMON2000 to switch the image from /bsd to /bsd.rd and back again at each step as the installer/`sysupgrade` does not do this for you. On AMD64, this should not be a problem. you should be able to a `sysupgrade` Worst case scenario might be temporarily changing /etc/installurl to ftp.openbsd.org to obtain the necessary files. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

Advice on serial port communication
Hi, I am trying to install OpenBSD (6.9) on a Beaglebone (Black, I presume -- it is a kit from Vilros). I followed the instructions at: https://ftp.openbsd.org/pub/OpenBSD/6.9/armv7/INSTALL.armv7 When I try to connect to the console via the serial port using cu, as described in the instructions, I get lines of "C"s. This happens at only 115200 baud rate. At all other baud rates, I get nothing. Any advice on what those "C"s mean. The serial cable I'm using is: https://www.amazon.com/GearMo%C2%AE-3-3v-Header-like-TTL-232R-3V3/dp/B004LBXO2A/ Thank you.

iwm0: fatal firmware error
Hello. My laptop (Lenovo Thinkpad T495s AMD Ryzen) reports an iwm0 fatal firmware error. I'm running 6.9 #29. System gets quite hot, systat shows 40-50% interrupt while idling. Networking works fine. Anybody else has this issue? Regards, Marco.

argv from bogus argc
While testing to determine command line arguments passed to a cgi file
using the *function 1*, I receive the message *output 1.*
one argument is passed and that is the name of the file.
However, testing with a bogus number 30 for argc in *function 2*, discloses
multiple arguments beyond the last null argument argv[1] see *output 2.*
There is also a null value at bogus argc number 29.
Why are these additional argv values generated?
*Function 1:*
/**/
void TestCommandLineArguments(int argc, char *argv[])
{
unsigned short int i = 0;
if (argc == 1) /* if one command line argument is passed */
{
PrintPageUpper();
while(i < argc)
{
printf("\t\t(i = %2$d) argc: %1$d, \
argv[%2$d]: \"%3$s\"\n", argc, \
i, argv[i]);
i++;
}
PrintPageLower();
exit(EXIT_SUCCESS);
}
if (argc != 1)
{
PrintPageUpper();
puts("\t\t(Multiple Arguments)");
PrintPageLower();
exit(EXIT_SUCCESS);

EVP_DIGESTINIT(3) vs. MD5(3) and my CPU
Hi, I did a search on marc.info on this but didn't come to a conclusion. So the subject already says it, the MD5(3) manpage says that the EVP functions should be used, ok. I'm hoping that using the EVP functions will give me hardware support at these hashing functions much like AESNI, however, how do I know that my CPU supports hardware accelleration of MD5, SHA1, or SHA256? What flags must I know on the cpu? I'm about to do a conversion on my main program which uses all these hash mechanisms to EVP, I'd love to get cpu support. If I don't get MD5 support I would replace it with a SHA1 or SHA2 function in my code. Here is a sample CPU on one of my vps's: cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT,SSE3,PCLMUL,SSSE3,FMA3,CX16,SSE4.1,SSE4.2,x2APIC,MOVBE,POPCNT,AES,XSAVE,AVX,F16C,RDRAND,HV,NXE,MMXX,FFXSR,PAGE1GB,RDTSCP,LONG,LAHF,CMPLEG,AMCR8,ABM,SSE4A,MASSE,3DNOWP,OSVW,TOPEXT,FSGSBASE,BMI1,AVX2,SMEP,BMI2,RDSEED,ADX,SMAP,CLFLUSHOPT,SHA,IBPB,SSBD,XSAVEOPT,XSAVEC,XGETBV1 I see AES (AESNI?), SHA (does this offload SHA hashing?). Best Regards, -peter
