Comment 13 Colin Macdonald 2022-08-16 04:09:16 UTC
For me it happens on one directory and not another, seemingly related to old formats(?)

Not working:
  * has .encfs5, which is binary junk
  * made by EncFS 1.3.2 (very old, I've had this dir for maybe 15 or so years)

Working:
  * has .encfs6, which is xml
  * made by EncFS 1.7.4

gdb trace, looks same as the autogen stuff above to me:

```
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff771a506 in EVP_CIPHER_CTX_set_key_length (c=0x5555555c3e80, keylen=20) at crypto/evp/evp_enc.c:985

(gdb) 
```

I plan to try some old fedora system to copy the files into a new encfs.  I'm not sure when this broken: possibly during my upgrade to Fedora 36 (I know it worked on Fedora 35 but I cannot be sure I have accessed this directory previously on Fedora 36 or not)

Comment 14 Ben Cotton 2023-04-25 17:25:01 UTC
This message is a reminder that Fedora Linux 36 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 36 on 2023-05-16.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '36'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 36 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 15 Ludek Smid 2023-05-25 17:54:22 UTC
Fedora Linux 36 entered end-of-life (EOL) status on 2023-05-16.

Fedora Linux 36 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
