You're ignoring the fact that the non-encrypted filesystem doesn't actually have to encrypt the filename. There is overhead involved in that. This overhead is no different in the overhead involved in encrypting the file contents. Your lower filesystem may have 512 bytes available to store data (I'm ignoring inode storage requirements here), but you can't create a 1 byte eCryptfs file because the design of eCryptfs pads out the file to multiples of 4096 bytes before encrypting it and storing it to the lower filesystem. It also requires 8192 bytes per file for cryptographic metadata storage. There is typically some trade-off between security and usability and this, unfortunately, is no different. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/344878 Title: file name too long when creating new file (ecryptfs_lookup: lookup_one_len() returned [-36] on lower_dentry) To manage notifications about this bug go to: https://bugs.launchpad.net/ecryptfs/+bug/344878/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
