[openssh-9.1p1-1] sshd fails to start on Odroid-C1

[slydder]

After the latest update of opennssh 9.1p1-1 sshd fails to start with the following error:

$this->bbcode_second_pass_code('', '# /usr/bin/sshd
getentropy failed')

The bug is reproducable on Odroid-C1 with kernel 3.10.107-5-ARCH.

I have the same issue on the same hardware. Reported here also: https://bugzilla.mindrot.org/show_bug.cgi?id=3487

This is the commit which broke compatibility.
The problem is that if I build the package on the Odroid or similar environment it will detect getentropy from the headers, but when calling it the system will return ENOSYS - Function not implemented error.
So theoretically it is not a bug of openSSH, instead it is a build issue.

$this->bbcode_second_pass_code('', '
# pacman -Rs local/linux-api-headers
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing linux-api-headers breaks dependency 'linux-api-headers>=4.10' required by glibc
:: removing linux-api-headers breaks dependency 'linux-api-headers' required by libbpf
')

glibc depends on the new linux-api-headers, but Odroid C1 uses a legacy kernel which is < 4.10.

I have patched the openssh package sources to not detect getentropy.
sshd can be run again with a build containing the patches
