>Description:
fsck have own signal handler for SIGINT for performing ckfini(0). In some cases
(eg: interrupting fsck on reply("USE JOURNAL") stage) it provokes segmentation
violation.
Look's like cgbufs[X].b_un.b_cg is not initialized here:
-- in ckfini() from fsutil.c --
for (cnt = 0; cnt < sblock.fs_ncg; cnt++) {
if (cgbufs[cnt].b_un.b_cg == NULL)
--
>How-To-Repeat:
Just send SIGINT (or hit Ctrl+C) for "USE JOURNAL?" question
% truncate -s1g /tmp/test.img
% mdconfig -a -t vnode -f /tmp/test.img
md0
% newfs -j /dev/md0
% fsck_ufs /dev/md0
** /dev/md0
USE JOURNAL? [yn] ^CSegmentation fault (core dumped)
