Summary |
0000547: tar archive corruption when packing unreadable files |
|
Description |
When trying to pack a file not readable in a tarball, the Busybox tar applet includes an header describing the file to the tar archive, but with no content. The resulting archive is corrupted.
For instance:
$ id
uid=500(johndoe) gid=100(users) groups=100(users)
$ ls -l file?
-rw-r--r-- 1 johndoe users 20 nov 2 2005 file1
-rw------- 1 root root 20 nov 2 2005 file2
-rw-r--r-- 1 johndoe users 20 nov 2 2005 file3
$ cat file1
this is file 1
$ cat file2
this is file 2
$ cat file3
this is file 3
$ ./busybox tar cvf test.tar file1 file2 file3
file3
file2
tar: file2: Cannot open: Permission non accord |
|
Additional Information |
BTW, tar reports errors when trying to create the archive, however the returned error code is 0!
Same thing when trying to list the content of the corrupted archived: BB tar failed to fully display it, but it still returns 0 as the error code... |
