Subject: [PATCH 29/30] lib-fs-resize: Prevent crash resizing FAT with very
|
||
|
|
deep directories
|
||
|
|
|
||
|
|
Resizing a FAT file system crashes in libparted/fs/r/fat/count.c
|
||
|
|
flag_traverse_dir() if the length of any path name in the file system
|
||
|
|
overflows the 512 byte file_name local buffer. Increase buffer to 4096,
|
||
|
|
PATH_MAX on Linux.
