Hi,
Bisect from today's next pointed me to:
commit 4de97efb578a094e8fbf279522d41eb9ece1e3e0
Author: Chandan Rajendra <[email protected]>
Date: Sat Dec 8 12:21:43 2018 +0530
fsverity: Move verity status check to fsverity_file_open
as a reason of "Operation not supported" when reading any file from
mounted ext4fs (from SD card). Rootfs from nfsroot works but reading
from /home with ext4fs fails.
Mounts:
192.168.1.10:/srv/nfs/odroidhc1 on / type nfs4
(rw,relatime,vers=4.0,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.12,local_lock=none,addr=192.168.1.10)
/dev/mmcblk0p2 on /home type ext4 (rw,relatime)
Configuration:
1. Arch ARM Linux
2. exynos_defconfig
- All my Odroid boards (ARMv7, Exynos)
Systemd: v239, v238
3. All boards boot from TFTP with NFS root (NFSv4)
No specific errors in boot log:

Let me know if you need any more data.
Best regards,
Krzysztof

Thanks Krzysztof. Ted, this is the same bug I pointed out in my review of this
patch yesterday (https://patchwork.kernel.org/patch/10719197/#22371523). Can
you fix or revert the two broken patches? Thanks,
- Eric

I don't think that's necessary. Due to the bug, ext4_file_open() and
ext4_setattr() always return -EOPNOTSUPP when !CONFIG_FS_VERITY.
I'm working on a fixed version of the two patches to replace the ones currently
in the fscrypt tree. Will send out soon.

Can you send me an compressed e2image of your sdcard?
e2image -Q /dev/mmcblk0p2 sdcard.qcow2
bzip2 -z sdcard.qcow2
Thanks!

Hi,
I have sent version V4 of the patchset now. My plan was to include the fix for
"Kconfig recursive dependency" issue reported for IA64 architecture. But I
would need some more time to understand the problem and provide a correct
fix. Hence the V4 patchset was sent with a fix to only address the problem
reported in this mail.

The fscrypt.git tree has been updated with for the problem. Apologies
for not testing the !CONFIG_FS_VERITY case.
