8021171c73 In fill_ip6(), the value of the pointer av changes before it is
free(3)ed. Thus, introduce a new variable to track the original
value.

a15b3b5dc2 fsck_ffs: Unsign some variables and make use of reallocarray(3).
Instead of casting listmax and numdirs to unsigned values just define
them as unsigned and avoid the casts. Use reallocarray(3).

While here, fs_ncg is already unsigned so the cast is unnecessary.

1fbe8b4c28 Always allow setting number of iterations for the first time.
Before this change it was impossible to set number of PKCS#5v2 iterations,
required to set passphrase, if it has two keys and never had any passphrase.
Due to present metadata format limitations there are still cases when number
of iterations can not be changed, but now it works in cases when it can.

f3f1c24017 Fix userland tools that don't check the format of routing socket
messages before accessing message fields that may not be present,
removing dead/duplicate/misleading code along the way.

Document the message format for each routing socket message in
route.h.

Fix a bug in usr.bin/netstat introduced in r287351 that resulted in
pointer computation with essentially random 16-bit offsets and

9efe0fc3f6 Switch back to non-IEC units for 1024 bytes
I was swayed a little too quickly when I saw the wiki page discussing
kB vs KiB. Switch back as none of the code in base openly uses
IEC units via humanize_number(3) (which was my next step), and there's
a large degree of dislike with IEC vs more SI-like units.

c7c342ccf1 savecore: fix space calculation with respect to minfree in check_space(..)
- Use strtoll(3) instead of atoi(3), because atoi(3) limits the
  representable data to INT_MAX. Check the values received from
  strtoll(3), trimming trailing whitespace off the end to maintain
  POLA.
- Use `KiB` instead of `kB` when describing free space, total space,
  etc. I am now fully aware of `KiB` being the IEC standard for 1024
  bytes and `kB` being the IEC standard for 1000 bytes.
- Store available number of KiB in `available` so it can be more
  easily queried and compared to ensure that there are enough KiB to
  store the dump image on disk.
- Print out the reserved space on disk, per `minfree`, so end-users
  can troubleshoot why check_space(..) is reporting that there isn't
  enough free space.

2cfeb7bc13 In fsck_ffs pass1, prevent the inosused variable from wrapping.
The loop that scans the used inode map when soft updates is in use
assumes that the inosused variable is signed.  However, ino_t is
unsigned, so the loop invariant is incorrect and the check for
inosused wrapping to < 0 can never be true.

Instead of checking for wrap after the fact just prevent it from
happening in the first place.

259c3ae367 Work around an issue with mksnap_ffs not working in chroot'ed environment.
The problem is that the statfs(2) system call used to determine the relevant
mount point returns path within real root in the f_mntonname, causing
nmount(2) system call to fail with ENOENT.

Use a bit of heuristics to skip over few starting path elements when it
happens until we hit an actual mount point.

For this to work properly the whole mount should be accessible within the
chroot, it's going to still fail if chroot only has access to a part of the
mounted fs.

fccd5b2db9 Add ipfw_pmod kernel module.
The module is designed for modification of a packets of any protocols.
For now it implements only TCP MSS modification. It adds the external
action handler for "tcp-setmss" action.

A rule with tcp-setmss action does additional check for protocol and
TCP flags. If SYN flag is present, it parses TCP options and modifies
MSS option if its value is greater than configured value in the rule.
Then it adjustes TCP checksum if needed. After handling the search
continues with the next rule.

f7f038e32a Allow superseding the lease renewal and rebind times.
Also make sure that the renewal is never more than 1/2 * expiry and
rebind never more than 7/4 * renewal (the default values in the spec).
This should allow adjusting high values from the server as well as
making sure the values from the server make sense.

Renewal and rebind times will be adjusted down if the expiry time is set
very high in a server, not the other way around. This change just makes
sure the values keep making sense.
