This commit replaces those with two new functions that simplify the code
and produce warnings that the syntax is deprecated. A small number of
sensible abbreviations may be explicitly added based on user feedback.
There were previously three types of strncmp use in ipfw:
- Most commonly, strncmp(av, "string", sizeof(av)) was used to allow av
to match string or any shortened form of it. I have replaced this
with a new function _substrcmp(av, "string") which returns 0 if av
is a substring of "string", but emits a warning if av is not exactly
"string".
- The next type was two instances of strncmp(av, "by", 2) which allowed
the abbreviation of bytes to "by", "byt", etc. Unfortunately, it
also supported "bykHUygh&*g&*7*ui". I added a second new function
_substrcmp2(av, "by", "bytes") which acts like the strncmp did, but
complains if the user doesn't spell out the word "bytes".
- There is also one correct use of strncmp to match "table(" which might
have another token after it without a space.
Since I changed all the lines anyway, I also fixed the treatment of
strncmp's return as a boolean in many cases. I also modified a few
strcmp cases as well to be fully consistent.
- Convert the (char *) cast+cast backs magic to
memcpy(3). Without this, the resulting code
is potentially risky with higher optimization
levels.
- Avoid same name when calling local variables,
as well as global symbols. This reduces
confusion for both human and compiler.
- Add necessary casts, consts
- Use new style function defination.
- Minor style.Makefile(5) tweak
- Bump WARNS?= from 0 to 6

- Use more ``const''s where suitable.
- Define strk() as a static function in global scope.
This avoids the "nested extern declaration" warnings.
- Use static initialization of strings, rather than
referring string constants through char *.
- Bump WARNS from 0 to 6.
complementing the existing special case of a not existing /dev prefix
with the recognition of an already existing /dev prefix.
This implicitly solves the following two issues related to working on
GEOM devices /dev/foo/bar (which have the GEOM provider name "foo/bar")
with the expected commands like "bsdlabel /dev/foo/bar":
1. the error "Geom not found" when trying to write or edit the BSD
label (because previously the incorrect GEOM name "bar" instead of
"foo/bar" was derived from "/dev/foo/bar").
2. the multiple times reported "magically introduced" partition offset
of 63 blocks and the resulting errors like "partition extends past
end of unit" and "partition c doesn't start at 0!".
This implicitly resulted because bsdlabel(8) determines the "MBR
offset" via GEOM and (intentionally) silently falls back to an offset
of 0 if it could not be queried (which is the case if the name was
incorrectly derived).
Usually (at least on PCs) the offset for the first slice is 63 blocks
and bsdlabel(8) automatically subtracts them from the absolute
offsets in the read on-disk BSD label, resulting in the display of an
effective offset of 0. If the GEOM query fails, the assumed offset of
0 is subtracted and an incorrect effective offset of 63 is displayed
and tried to be worked upon.

because atol() doesn't know how to parse hexadecimal or octal numbers and at
least one of the options of ffsinfo(8) would be easier to use if it did.
Changing atol() -> strtol() allows one to use hex masks for -l MASK, i.e.:

special-purpose code to display status for an interface for
state that was not address-oriented. This status reporting
was merged in to the address-oriented status reporting but
did not work for link address reporting (as discovered with
fwip interfaces). Correct this mis-merge and eliminate the
bogus kludge that was used for link-level address reporting.
o add an af_other_status method for an address family for
reporting status of things like media, vlan, etc.
o call the af_other_status methods after reporting address
status for an interface
o special-case link address status; when reporting all
status for an interface invoke it specially prior to
reporting af_other_status methods (since it requires the
sockaddr_dl that is passed in to status separately from
the rtmsg address state)
o correct the calling convention for link address status;

After this change, when component is disconnected because of an I/O error,
it will not be connected and synchronized automatically, it will be logged
as broken and skipped. Autosynchronization can occur, when component is
disconnected (on orphan event) and connected again - there were no I/O
error, so there is no need to not connected the component, but when there were
writes while it wasn't connected, it will be synchronized.
This fix cases, when component is disconnected because of I/O error and can be
connected again and again.
- Bump version number.
- Implement backward compatibility mechanism. After this change when metadata in
old version is detected, it is automatically upgraded to the new (current)
version.
