^^^^^^^^^^
This is indeed not a valid file descriptor.
ioctl call like the above is typically done by stdio.h functions
(like fopen, fprintf, etc).
I need your help in identifying the problem. Message is definitely coming from
here:
report_error:
if (ENABLE_FEATURE_CLEAN_UP)
free(filteropts);
if (rc && errno == EBUSY && ignore_busy)
rc = 0;
if (rc < 0)
bb_perror_msg("mounting %s on %s failed", mp->mnt_fsname,
mp->mnt_dir);
at the end of singlemount() function.
Can you edit singlemount() and add debug prints approximately like this:
static int singlemount(struct mntent *mp, int ignore_busy)
{
int rc = -1, vfsflags;
char *loopFile = 0, *filteropts = 0;
llist_t *fl = 0;
struct stat st;
printf("HERE 1\n");
vfsflags = parse_mount_options(mp->mnt_opts, &filteropts);
printf("HERE 2\n");
// Treat fstype "auto" as unspecified.
if (mp->mnt_type && strcmp(mp->mnt_type,"auto") == 0)
mp->mnt_type = 0;
// Might this be an CIFS filesystem?
if (ENABLE_FEATURE_MOUNT_CIFS
&& (!mp->mnt_type || strcmp(mp->mnt_type,"cifs") == 0)
&& (mp->mnt_fsname[0]=='/' || mp->mnt_fsname[0]=='\\')
&& mp->mnt_fsname[0]==mp->mnt_fsname[1]
) {
len_and_sockaddr *lsa;
char *ip, *dotted;
char *s;
printf("HERE 3\n");
rc = 1;
and so on, then recompile busybox and rerun the same mount command?
