Hi I'm experiencing a bizarre problem with ECryptFS keys. Preconditions: - 3.7-rc4 mainline kernel. - Minimal RootFS made with BuildRoot, bundled into kernel image (initramfs). - Fresh boot. - 32 MB FAT loopback image mounted on /mnt. I execute the following sequence: mykeyid=`keyctl add encrypted 1000100010001000 "new ecryptfs user:device-key 64" @u` echo $mykeyid keyctl print $mykeyid keyctl list @u mount -t ecryptfs -oecryptfs_sig=1000100010001000,ecryptfs_fnek_sig=1000100010001000,ecryptfs_cipher=aes,ecryptfs_key_bytes=32 /mnt /mnt echo "mount returned $?" mount|grep ecryptfs keyctl list @u Execution: # mykeyid=`keyctl add encrypted 1000100010001000 "new ecryptfs user:device-key 64" @u` # echo $mykeyid 541909842 # keyctl print $mykeyid keyctl_read_alloc: Cannot allocate memory # EXPECTED # keyctl list @u 1 key in keyring: 541909842: --alswrv 0 0 encrypted: 1000100010001000 # mount -t ecryptfs -oecryptfs_sig=1000100010001000,ecryptfs_fnek_sig=1000100010001000,ecryptfs_cipher=aes,ecryptfs_key_bytes=32 /mnt /mnt # echo "mount returned $?" mount returned 0 # mount|grep ecryptfs /mnt on /mnt type ecryptfs (rw,relatime,ecryptfs_fnek_sig=1000100010001000,ecryptfs_sig=1000100010001000,ecryptfs_cipher=aes,ecryptfs_key_bytes=32) # NOT EXPECTED. Shouldn't this fail? # keyctl list @u 1 key in keyring: 541909842: --alswrv 0 0 encrypted: 1000100010001000 Why does mount work?
