"dumpsize" in the on-disk core header is in pages, but, unfortunately,
c.size in our kcore format is an unsigned 32-bit int, gross.
We sleaze it, using a 64-bit int internally here and handing it to
libkvm as a *signed* 32-bit int. Won't always work, but shouldn't be
broken any worse than it is now, and sometimes work better.
We must fix the kcore format and libkvm.
to automatically bring up interfaces, then we should move that code into
ifconfig(8) and out of the kernel, not cycle the interface up and down. Fixes
PR 9400 -- ifconfig(8) was not working as documented.
If the input to 'disklabel' (non -i) referenced a partition two or more
larger than that permitted by npartitions it would error out with 'bad
partition name' (and the option given to re-edit if -e). If a partition one
larger was used it would be dropped from the disklabel with a warning and the
label written anyway! The (off by one) check for a bad partition name was
against npartitions anyway, rather than MAXPARTITIONS. npartitions was just
read from the disklabel and could have been set to an arbitrary value.
Given 'disklabel -i' sets npartitions automatically, make the normal case
check partition names against MAXPARTITIONS, and if necessary increase
npartitions to the size needed to hold the last partition used.
While here remove two 'write only' uses of a 'part' variable.
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

to 30 seconds, per PR 25734. I've seen this problem myself. I think
that scsictl should:
1. accept a timeout flag/parameter to set the timeout to an arbitrary
value other than the default.
2. support a verbose mode that would report the timeout value before
the command is started, and then report how long the command actually
took to complete, though I suppose the latter could also be done
by using time(1).
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.
