https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204643 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@FreeBSD.org Reporter: gordon778@mail.ru Created attachment 163261 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=163261&action=edit 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.
