Subject: ext4/004 hangs with -o inlinecrypt,test_dummy_encryption
Date: Sun, 7 Dec 2025 22:59:54 -0800 [thread overview]
Message-ID: <aTZ3ahPop7q8O5cE@infradead.org> (raw)
Hi all,
I've just been wanting to test my changes to the inline encruption
fallback code, and it seems like ext/004 (the only ext4 dump test)
hangs when using the following options:
export MKFS_OPTIONS='-O encrypt'
export MOUNT_OPTIONS="-o inlinecrypt,test_dummy_encryption"
I thought I did not see this before, but it reproduces back to at least
Linux 6.17. This is in an uptodate Debian trixie VM. The dump/restore
process look like in weird states:
4727 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir
4728 ttyS0 T 0:00 /usr/sbin/restore -urvf -
4729 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir
4730 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir
4731 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir
4732 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir
