[IMPACT]
Glibc in jammy and kinetic is affected by the following bug :
https://sourceware.org/bugzilla/show_bug.cgi?id=29953
When cpuid reports no information on a shared cache, the
x86_non_temporal_threshold will be set to zero, causing memcpy/memset to
behave wrong for mid-sized operations. sysdeps/x86/dl-cacheinfo.h indicates
that the minimum value must be 0x4040, but this is not enforced for the
default value.
The issue was reported because jammy tdx instances are failing to boot
(crashing) on azure. The bug has been resolved upstream in
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=48b74865c63840b288bd85b4d8743533b73b339b
[TEST CASE]
Test case requires an azure tdx instance.
Microsoft has tested a test package with the above commit and
confirmed that instances boot successfully.
[REGRESSION POTENTIAL]
The patches have been accepted upstream. They modify code for x86 architecture, so any
potential regression would affect x86.
[OTHER]
In jammy we need 2 commits :
