Changing this parameter will break NFSv4 ACL support in rsync, which is unacceptable. At some future time, we could probably expose FreeBSD's native NFSv4 ACLs as NDR-encoded system.nfs4acl xattrs and synchronize them through rsync's xattr support. That's probably somewhat far in the future and risks regression. Rsync is one of those tools that must not regress.

If we remove the patch for nfs4 ACLs, then FreeBSD to FreeBSD rsync will no longer be able to synchronize the native NFSv4 ACLs. What if you specify "--no-perm"?

More isolation: the port's files/extrapatch_acls changes change the bits on the wire, breaking compatibility with other builds of rsync. xattrs come after and are reading garbage on the wire.

Confirmed that building without FLAGS enabled triggers the failure.

Here's the device being backed up (via SSH):

Trying to use rsync to backup a linux box (a simple Raspbian box). Flags are
--fake-super --progress -aAXSvzhe ssh --exclude={"/dev/","/proc/","/sys/","/tmp/","/run/","/mnt/","/media/*","/lost+found"}
The supplied rsync fails with:
receiving incremental file list
Invalid xattr name received (missing trailing \0).
rsync error: error in file IO (code 11) at xattrs.c(829) [Receiver=3.1.3]
Building a fresh copy of rsync from ports (in a fresh jail) gets a working rsync. It looks at a minimum like there's something different about the build process that's not expected:

This would seem to indicate that the FLAGS_EXTRA_PATCHES part of the port isn't being processed correctly in the default build.
