[Qemu-devel] [PATCH v2] tpm: Use EMSGSIZE instead of EBADMSG to compile on OpenBSD |
Date: |

EBADMSG was only added to OpenBSD very recently. To make QEMU compilable
on older OpenBSD versions use EMSGSIZE instead when a mismatch between
number of received bytes and message size indicated in the header was
found.
Return -EMSGSIZE and convert all other errnos in the same functions to
return the negative errno.
