Bug#970460: [Bug libc/23960] [2.28 Regression]: New getdents{64} implementation breaks qemu-user

Show all headers | View raw

Hi Adrian,

could you work around the problem by starting an i386 VM on
your amd64 system, and then running the qemu-user buildds on
that? The return values from the syscalls will natively be
correct 32 bit there…

In the meantime, someone found that this bug also hits without
any qemu involvement:

It was also found that this cannot be fixed “only” in qemu.
The GNU libc people are discussing…
