Hi Dmitry,

If the failing test is the unit test func_reentrancy_autotest, that is
being looked into , as it seems like the test case does not reliably run.
It passes / fails between different systems running both on bare metal and
in virtual environments, on different OSes and architectures.

Do you have a link to your patch in patchworks or the lab dashboard?

Cheers,
Lincoln

Size of string constant symbol may be larger than its length
measured up to NUL terminator. In this case pmdinfogen included padding
bytes after NUL terminator in generated source, yielding incorrect code.

Always trim string data to NUL terminator while reading ELF.
It was already done for COFF because there's no symbol size.

There are CI failures that seem unrelated to this patch:
some tests with NICs that I can't check
and an Arch Linux build failure that I failed to reproduce.
GitHub Actions are passing.
Are these known CI bugs or does this patch need any corrections?
