A quick look at 2.4 (linux-2.4.26-rc1-devmapper-ioctl.patch) suggests:
dm-ioctl.c:805 needs changing so that the target status function is never
called with a buffer size limit of zero:
- if (remaining < sizeof(struct dm_target_spec)) {
+ if (remaining <= sizeof(struct dm_target_spec)) {
2 status functions fail to respect maxlen when looping:
mirror_status() needs to ensure maxlen > sz always
stripe_status() needs to ensure maxlen > offset always
