file name too long when creating new file (ecryptfs_lookup: lookup_one_len() returned [-36] on lower_dentry) still exists

[Wuestenschiff]

I still problem from bug #344878 even though it is marked as fixed.

Had problem downloading torrents with long file names in Tranmission. But it isn't a problem with transmission.

Reproduce:
- cd to folder in encryptet home
$ vi test.txt
$ mv test.txt 111111111222222222333333333444444444555555555566666666667777777777888888888899999999990000000000111111111122222222233333333334444444444555555555566666666667777777777888888888899999999990000000000.txt

expected result:
file should be renamed to new name (~200 letters)

real result:
mv: accessing `111111111222222222333333333444444444555555555566666666667777777777888888888899999999990000000000111111111122222222233333333334444444444555555555566666666667777777777888888888899999999990000000000.txt': File name too long

Thanks for using eCryptfs!

This is not a bug. eCryptfs can only store filenames of 143 characters when mounted on top of filesystems that support 255 character filenames. This is due to encryption and metadata overhead. eCryptfs is working as designed in your description.
