Public bug reported:
I set up an ecryptfs volume some time ago, using aes crypto. Now, nearly
six months later, after a few minor kernel upgrades, I'm unable to
access the same volume from the same machine; the mount seemingly
succeeds but the data remains encrypted. The only apparent anomaly in
the mount process is the following:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
Seeing that aes is not loaded (which I find strange), I try to load aes
manually:
# modprobe -v aes
insmod /lib/modules/2.6.35-28-generic/kernel/arch/x86/crypto/aesni-intel.ko
WARNING: Error inserting aesni_intel
(/lib/modules/2.6.35-28-generic/kernel/arch/x86/crypto/aesni-intel.ko): No such
device
insmod /lib/modules/2.6.35-28-generic/kernel/drivers/crypto/padlock-aes.ko
WARNING: Error inserting padlock_aes
(/lib/modules/2.6.35-28-generic/kernel/drivers/crypto/padlock-aes.ko): No such
device
But I still get aes "(not loaded)".
# lsmod | grep aes
aes_x86_64 7936 3
aes_generic 27631 1 aes_x86_64
# find /lib/modules/2.6.35-28-generic/ -name 'aes*'
/lib/modules/2.6.35-28-generic/kernel/crypto/aes_generic.ko
/lib/modules/2.6.35-28-generic/kernel/arch/x86/crypto/aes-x86_64.ko
/lib/modules/2.6.35-28-generic/kernel/arch/x86/crypto/aesni-intel.ko
I will go back to an older kernel and see if that works better.
