Subject: nfs-utils: v3 mounts broken due to statx() returning EINVAL
Date: Tue, 8 Oct 2019 22:23:56 +0200 [thread overview]

Hi,
we have some user reporting that NFS v3 mounts are broken
when using glibc-2.29 and linux-4.9.x (4.9.128) because
statx() with mask=STATX_BASIC_STATS returns EINVAL.
Looks like this isn't happening with <nfs-utils-2.4.1 or
newer kernels.
The following workaround was confirmed to be working:
--- a/support/misc/xstat.c 2019-06-24 21:31:55.260371592 +0200
+++ b/support/misc/xstat.c 2019-06-24 21:32:29.098777436 +0200
@@ -47,6 +47,8 @@
statx_copy(statbuf, &stxbuf);
return 0;
}
+ if (errno == EINVAL)
+ errno = ENOSYS;
if (errno == ENOSYS)
statx_supported = 0;
} else
Bug: https://bugs.gentoo.org/688644
At the moment I have no clue whether this is kernel/glibc or
nfs-utils related; if the patch is safe to apply...
Any help is appreciated. Thanks!
