Subject: ptrace + ioctl( LOOP_SET_FD ) brokeness.
Date: Thu, 13 Nov 2003 14:55:06 -0700 [thread overview]
Message-ID: <20031113215506.GO23534@lanl.gov> (raw)
The following hangs reliably on 2.4.22 (test on x86 and x86_64):
strace mount -o loop somefile /mnt
the mount program ends up wedged in the D state. The last file lines
of the strace look like this:
open("/dev/loop0", O_RDONLY|O_LARGEFILE) = 3
ioctl(3, 0x4c03, 0xbfffded0) = -1 ENXIO (No such device or address)
close(3) = 0
open("xxx", O_RDWR|O_LARGEFILE) = 3
open("/dev/loop0", O_RDWR|O_LARGEFILE) = 4
mlockall(MCL_CURRENT|MCL_FUTURE) = 0
ioctl(4, 0x4c00
