Package: src:linux
Version: 5.19.11-1
Severity: important
Dear Maintainer,
I have a XEN hypervisor running with some VMs (everything based on Debian).
After updating to the Kernel to 5.19 (from 5.18.0-4), some
binaries are falling to execute. If the VMs are started with Kernel 5.18.0-4
they are running fine.
One example is wget which results in this kernel log:
[ 366.744374] traps: wget[3327] trap invalid opcode ip:7fcabc94fb0a
sp:7fffdd212c80 error:0 in libgnutls.so.30.34.1[7fcabc837000+12f000]
After googling a little I found this stackoverflow problem report:
https://stackoverflow.com/questions/65676095/illegal-instruction-core-dumped-after-packages-upgrade-on-centos-8
And indeed there is some difference in /proc/cpuinfo:
5.19:
flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush mmx
fxsr sse sse2 ss ht syscall nx rdtscp lm constant_tsc rep_good nopl cpuid
tsc_known_freq pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 movbe popcnt aes f16c
rdrand hypervisor lahf_lm abm 3dnowprefetch cpuid_fault ssbd ibrs ibpb stibp
fsgsbase bmi1 bmi2 erms rdseed adx clflushopt md_clear
5.18:
flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush mmx
fxsr sse sse2 ss ht syscall nx rdtscp lm constant_tsc rep_good nopl cpuid
tsc_known_freq pni pclmulqdq ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes
xsave avx f16c rdrand hypervisor lahf_lm abm 3dnowprefetch cpuid_fault ssbd
ibrs ibpb stibp fsgsbase bmi1 avx2 bmi2 erms rdseed adx clflushopt xsaveopt
xsavec xgetbv1 md_clear
So the flags for "fma xsave avx2 bmi2 xsaveopt xsavec xgetbv1 md_clear" are
missing, which might result in gnutls failures.
regards
Patrick
