These are the current occurrences of ENODATA:
src/storage/storage_backend.c:
if (errno != ENODATA && errno != ENOTSUP) {
tests/securityselinuxlabeltest.c:
if (errno == ENODATA) {
src/util/viruuid.c:
#ifndef ENODATA
# define ENODATA EIO
src/util/virrandom.c:
return n < 0 ? errno : ENODATA;
The first is inside a '#if WITH_SELINUX' block, so FreeBSD is
not going to hit it. The second one is a SELinux-specific test,
and it's not compiled on FreeBSD.
The third one is where ENODATA gets defined, as you mention in
your commit message, and the fourth one where it's used.
Note that ENODATA is not being used in viruuid.c... I guess
the code that prompted the definition has since been removed.
So I think you should rather move the definition from viruuid.c
to virrandom.c instead of virutil.h.
ACK with that changed.
Cheers.
