support for Endian-Independent FFS and Apple UFS is disabled unless FFS_EI=1
and APPLE_UFS=1 are added to CRUNCHENV, respectively.
This reduces the size of ramdisk image for atari by over 15KB.
Thanks tsutsui and christos for their useful comments.
In the prototype of the gzclose() function of changed from:
typedef struct gzFile_s *gzFile; /* semi-opaque gzip file descriptor */
to:
typedef voidp gzFile;
This caused type mismatch when calling funopen(3) as:
'int (*)(void *)' != 'int (*)(struct gzFile_s *)'
Cast gzclose to (int (*)(void *)) when used in funopen(3).
default, build a handful of tools as n64 so they work properly.
unfortunately, they're also static as dynamic n64 has a problem.
of these tools pstat is probably the lowest hanging fruit to convert
to sysctl. systat would be close were it not for the netstat screen,
which includes netstat itself.
the rest are difficult to perhaps foolish.
the upside is that netstat, pmap and fstat all work properly now.
routed previousely ignored local routes, which have RTF_LOCAL flag, because
such routes have RTF_LLINFO and routed ignored routes having the flag. When
we obsoleted RTF_LLINFO, we removed the ignoring logic from routed, then
routed started removing local routes unexpectedly.
Fix this behavior by teaching local routes to routed to ignore them.
kardel@ reported the issue and helped testing, thanks!
small or wildly too large intervals, but it did allow intervals that
failed at poll(). Since that's signed integer overflow and thus UB,
better not to.
Reject packet intervals < 1 ns as they lead to infinite loops adding
zero timespecs.
Fix the behind-schedule behavior so it doesn't spend all its time in
that loop adding very small timespecs. Try ping -c 500 -i 0.000000001
to see this in action with the old ping.
Check for values between INT_MAX and LONG_MAX (if they're different)
when using strtol to get an int. This applies to the -c and -l options;
the other uses were already checked.
Also limit the inter-packet interval given with -i to values that
don't cause integer overflow calling poll() with milliseconds.
Really large intervals (the number is read as floating point) can
produce positive poll() values but negative integers when converted to
struct timespec; this produces behavior akin to using -l at first and
could be construed as a local DoS vulnerability.
Now you can do
# mount_puffs -o rdonly rot13fs#/home/foo /mnt/rot13
or in fstab
rot13fs#/home/foo /mnt/rot13 puffs rdonly
to start rot13fs with arguments identical to
# rot13fs -o rdonly /home/foo /mnt/rot13
parameters/enables for error recovery, similar to {get,set}cache.
Many old SCSI disks shipped with reallocation disabled, albeit supporting it.
Minor (cosmetic) fixup of scsi_disk_pages while there.

OK christos@
previously attempting to use mount -t ext2 like myself would result in
the warning "mount: mount_ext2 not found for /mnt", which (if you're me)
can be misunderstood as "/mnt is not an ext2 filesystem"...
change it to "mount: mount_ext2 not found"
Strictly this shouldnt be (and hasn't been for almost a year) a problem,
but there are compilers that warn about locals shadowing globals (which
this is/was) and it is easy to avoid, so ... No functinal difference.
mask set is non-contiguous. We don't prohibit setting such things
(even if they are basically useless) so they can be set by accident.
ifconfig ifN 10.0.0.1 netmask 225.0.0.0
produced
ifN .. inet 10.0.0.1/8
with the previous form (since 225 is 0xE1), now it produces
ifN ... inet 10.0.0.1 netmask 0xe1000000
If the "netmask" form ever appears in ifconfig output, it (now)
means that the netmask is non-contig, which should make that case
obvious (whther intended, or set by accident)
Julian Elischer [1] and the Mach 2.5 Installation notes [2].
I was unable to pin point the exact version of Mach the fdisk utility appeared
as I didn't find documentation older than version 2.5 & no source code or repo
history. fdisk utility appears as a separate utility[3] in v2.5. Due to this,
I've avoided stating the exact version fdisk first appeared in Mach.

e2di_size_high; even Linux ext2 filesystem code actually uses it
unconditionally this way and ext4 code finally also calls it that way
in their struct definition too; if there was any trace of this for other
purpose it's long gone
sysctl variable using ?= fails with EPERM, don't print an error
message.
Ideally setting a sysctl to the same value it already has should also
not fail regardless of permissions, but this would need to be done in
the kernel.
so they can't illegally reenter libc.
Fixes the problem Greg A. Woods describes in PR 51267, which might or
might not be the original submitter's problem.
The superblock field that distinguishes between 4.2BSD and 4.4BSD
inodes is really only relevant on a UFS1 file system. Make sure that
it is a UFS1 fs before using fs_old_inodefmt.
Note that the NetBSD newfs and mkfs utilities initialize fs_old_inodefmt
even for UFS2, so problems were apparent only on file systems created
by other operating systems, for example, FreeBSD.
distinct and allowing this makes certain useful tasks possible, such as
fixing an unpopulated /dev while a tmpfs is mounted over it.
However, require the paths to be different, as mounting a path directly over
itself has the side effect of causing any other mount points within that path
to no longer be accessible, and is difficult to unmount when done on /.
(e.g. umount_ffs, umount_nfs, etc.) exec it instead of calling
unmount(2).
Closes PR 698.
Note that the original plan for the PR also involved adding a generic
facility to store an alternate FS type name in the kernel to use when
unmounting. This was intended to support filesystems implemented as
loopback nfs servers, where the visible mount would be of type "nfs"
pointing at localhost; in that case one would want to be able to
provide an additional string in order to run an unmount program that
would both remove that mount and also shut down the loopback nfs
server daemon.
However, in the 21+ years since the PR was filed, loopback nfs servers
have gone out of favor (for good reasons) so I don't see any need to
worry about this case at present, especially since the PR has been
hanging around this long anyway. (If anyone still has a loopback nfs
server that they want to use a custom unmount program with, file a new
PR and assign it to me and I'll deal with it specifically in the nfs
mount args structure, which unmount already knows how to retrieve and
examine.)
It is my understanding that filesystems implemented with fuse (which
has displaced the loopback nfs server model) can already set the FS
type field so no further work is needed to allow them to use a custom
unmount program. If this is not the case, please let me know and I'll
attend to it.
There is no longer any need that I see to provide a general facility
for storing an alternate filesystem type name.
(One might also ask whether there's any real need for this
functionality at all any more; this is a fair question, but (a) the
change is small and (b) there are certainly cases when doing FS
research where you want a custom unmount program; been there & done
that.)
- debug log is now using syslog
- seperate options for log level and foreground mode
- writes a pidfile so that /etc/rc.d/iscsid works
Now links with libutil for pidfile(), the functions login() and logout()
needed to be renamed to avoid a conflict.
- drops the nothreads option
- handles signals to shut down gracefully
- the driver may also shut down the daemon when it terminates
Currently this cannot work as the driver can only terminate when
the daemon has closed the driver file handle.

By this change, nexthop caches (IP-MAC address pair) are not stored
in the routing table anymore. Instead nexthop caches are stored in
each network interface; we already have lltable/llentry data structure
for this purpose. This change also obsoletes the concept of cloning/cloned
routes. Cloned routes no longer exist while cloning routes still exist
with renamed to connected routes.
Noticeable changes are:
- Nexthop caches aren't listed in route show/netstat -r
- sysctl(NET_RT_DUMP) doesn't return them
- If RTF_LLDATA is specified, it returns nexthop caches
- Several definitions of routing flags and messages are removed
- RTF_CLONING, RTF_XRESOLVE, RTF_LLINFO, RTF_CLONED and RTM_RESOLVE
- RTF_CONNECTED is added
- It has the same value of RTF_CLONING for backward compatibility
- route's -xresolve, -[no]cloned and -llinfo options are removed
- -[no]cloning remains because it seems there are users
- -[no]connected is introduced and recommended
to be used instead of -[no]cloning
- route show/netstat -r drops some flags
- 'L' and 'c' are not seen anymore
- 'C' now indicates a connected route
- Gateway value of a route of an interface address is now not
a L2 address but "link#N" like a connected (cloning) route
- Proxy ARP: "arp -s ... pub" doesn't create a route
