Bug#1019855: Fwd: libc6: immediately crashes with SIGILL on 4th gen Intel Core CPUs (seems related to AVX2 instructions), bricking the whole system

2022-10-04 Thread debian-bug-report
Is there an easy way to unbrick a system affected by the issue? such as a kernel-line option or a configuration file in /etc? I don't see how I can set a GLIBC_TUNABLES environment variable for the whole system. I was trying during my testing to set such option globally somehow, but failed, tho

/proc/cpuinfo without microcode update is already attached somewhere above in the bug report, the new one after update is as follows: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 60 model name : Intel(R) Core(TM) i3-4000M CPU @ 2.40GHz stepping

I can confirm updating the microcode by installing the intel-microcode package and rebooting does indeed mitigate this issue. An LXC container that was previously bricked due to update now starts and seems to behave fully normally. [0.00] microcode: microcode updated early to revision

Hello, sorry for delayed response, I've managed to collect and analyze a few coredump files with valid symbols (I installed libc6-dbg and dpkg-dev, and pointed gdb at Debian's debuginfod server, also used apt-get source to get the sources for libc6). It seems there are at least 3-4 distinct pl

and end up with bricked system. I will proceed to try using `clearcpuid=293` kernel flag myself, but consider how many distros depend on Debian, live CDs etc, with people unable to figure out why their system became useless, unable to trace the source, and blaming it just on Linux... I

Bug#563113: slapd: TLSCipherSuite not working - gnutls cipher spec is unclear!?

hi Russell, its pretty unclear which syntax to use with the TLSCipherSuite parameter of slapd.conf ... The old SSL syntax used with 2.3x versions of slapd was pretty clear with that and could be adapted from the openssl documentation. Today I switched a testing platform from etch to lenny (fresh
