Vahap Emin Agaogullari c8d29e9f15 PROFINET: DCP Option dissection updated
DCP Frames with Reserved Option dissection changed
short time ago. There isn't a predefined suboption
for Reserved option in the standard. But in this
implementation it dissected like control suboption.
This is not true and creates malformed frames in some
dcp pcaps. This implementation is reverted.
Wireshark will dissect undefined bytes as paddings
just like before.

João Valverde 133b0c583f Move epan/wmem/wmem_scopes.h to epan/
This header was installed incorrectly to epan/wmem_scopes.h.

Instead of creating additional installation rules for a single
header in a subfolder (kept for backward compatibility) just
rename the standard "epan/wmem/wmem.h" include to
"epan/wmem_scopes.h" and fix the documentation.

Now the header is installed *correctly* to epan/wmem_scopes.h.

Martin Tschoepe d9a93acc93 PROFInet: Correct handling for multiple APIs
When dissecting messages with multiple API types

This results in only partial parsing of the elements.

This fix ensures that all parts of the message are taken
into account and dissected correctly.

Guy Harris 57a1514ac7 Cast away the return value of g_strlcpy() and g_strlcat().
Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation.  Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).

João Valverde 7f105d3981 CMake: Use CheckAPI's abort/termoutput with dissectors only
I believe this was the original intention, to use these API restricitons
with dissectors only (not that I necessarily agree with that policy either),
and through copy-paste and lack of clear guidelines it spread to other
parts of the build.

Rename the checkAPI groups to make it very clear that this is dissector-only.

This doesn't mean, of course, that good programming practices shouldn't be
followed everywhere. In particular assertions need to be used properly.
Don't use them to catch runtime errors or validate input data.

This commit will be followed by another removing the various ugly hacks
people have been using to get around the checkAPI hammer.

Basak Kalfa 91418775aa PROFINET: IOCS and IOData object dissection with Multi AR
when a new AR is established between devices which already
has another AR, same station_info was used and it caused wrong
dissection problem of IOCS and IOData objects of related AR.
In order to fix problem, new struct is added in order to match
station_info and corresponding ARs. New struct is used for
keeping ARUUID, related inputCR and outputCR frame IDs and
setup/release frame numbers of ARs. ARUUID's are used for
adding station_info data to their corresponding conversations.
If matching ARUUID and Frame IDs are found in RTC frame
dissection, then corresponding IOCS and IOData objects are
dissected.

Basak Kalfa 4e595577f3 PROFINET: DHCP suboption undefined bytes
There are undefined bytes which must be included in DHCP

words, there are still bytes after dissection of defined
parameters finish but DCP block length does not finish.
In order to solve the problem, these bytes are included in
DHCP suboption block and marked Undefined. The byte number
can be 1, so bytes word in pn_user_data is changed to byte.

Guy Harris e1d9a226a2 Fix the type of arrays of pointers to hf_ values for bitfield routines.
The static arrays are supposed to be arrays of const pointers to int,
not arrays of non-const pointers to const int.

Fixing that means some bugs (scribbling on what's *supposed* to be a
const array) will be caught (see packet-ieee80211-radiotap.c for
examples, the first of which inspired this change and the second of
which was discovered while testing compiles with this change), and
removes the need for some annoying casts.

Also make some of those arrays static while we're at it.

Update documentation and dissector-generator tools.

Moshe Kaplan fd7895d37c Replace instances of wmem_alloc with wmem_new
This commit replaces instances of
  (myobj *)wmem_alloc(wmem_file_scope(), sizeof(myobj))
and replaces them with:
  wmem_new(wmem_file_scope(), myobj)
to improve the readability of Wireshark's code.

The replacement locations were identified with grep
and replaced with the Python script below.

grep command:
  egrep "wmem_alloc0?\(wmem_file_scope\(\), sizeof\([a-z_]+\)\)" . -R -l

python script:

import re
