Summary

0000793: mdev -s fails with "Illegal argument"

Description

The context: Using busybox inside initramfs on a 2.6.15 kernel. ENABLE_FEATURE_MDEV_CONF is off.

The symptom: mdev -s reports "mknod /dev/hdc failed: Invalid argument"

Root cause: /sys/block/hdc/dev contains "22:0\n" ..The newline character confuses the code that converts the minor device number, causing the value of "minor" to be (decimal) -38 (which is '\n' - '0').

The fix:

In mdev.c, replace:

for (s = temp; *s; s++) {
with:
for (s = temp; *s && *s != '\n'; s++) {
