Bug ID: 204643
Summary: [msdosfs] [panic] Crash while accessing files with
large, non-english names
Product: Base System
Version: 9.3-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs at FreeBSD.org
Reporter: gordon778 at mail.ru

Kernel config file
How-to-repeat:
1. Create file with large name, non-english (130 symbols
enough) on msdos fat disk. This must be done under ms windows
(FreeBSD does not allow shot in your leg and create file with
name > 127 non-english symbols on fat fs). Under the windows long
non-english filenames
(127+ symbols) is correct and can be easily and accessed.
2. Mount disk on FreeBSD system like
"mount_msdosfs -o longnames -D cp1251 -L ru_RU.UTF-8 /dev/daX /mnt"
(or use the your language settings in -D and -L)
3. Try "ls /mnt/directory-with-large-name"
You get "panic: stack overflow detected; backtrace may be corrupted"
I guess this is the same bug #141897
And, i guess this happening because locale uses multibyte encoding (UTF-8). But
utf-8 the only way and this is the future.
Unfortunately fat file systems are widespread, and i from time to time
encounter with this.
Kernel config in attachment.
