Hi all,
I recently compiled a Linux kernel 2.4.24 with RSBAC v1.2.2.
I usually compile kernels with initrd, and in booting the newly
created RSBAC kernel I got and error:
do_umount() [sys_umount()]: umount failed -> calling rsbac_mount for
Device 01:00
umount: /initrd: device is busy
I'm sure it's not a problem with RSBAC privilege because there's no
"NOT_GRANTED by " on the screen, in the log or in /proc/rsbac-info/rmsg
I tested the kernel on a Debian Woody and on a Mandrake 9.2 with the same
results.
I run lsof and infact there are some open files in initrd.
# lsof | grep initrd
rsbacd 30 root txt REG 1,0 70104 17 /initrd/bin/mount
rsbacd 30 root mem REG 1,0 90210 27 /initrd/lib/ld-linux.so.2
rsbacd 30 root mem REG 1,0 1153784 28 /initrd/lib/libc.so.6
rsbacd 30 root 0u CHR 5,1 21 /initrd/dev/console
rsbacd 30 root 1u CHR 5,1 21 /initrd/dev/console
rsbacd 30 root 2u CHR 5,1 21 /initrd/dev/console
I really don't know how to solve this problem, and I don't like having
initrd mounted.
Maybe I did something wrong?
Thanks in advance!
Nicola
