Address
|
|
|
|
|
|
|
|
The Address field is four octets. The value 0xFFFFFFFF indicates
|
|
|
|
that the NAS Should allow the user to select an address (e.g.
|
|
|
|
Negotiated). The value 0xFFFFFFFE indicates that the NAS should
|
|
|
|
select an address for the user (e.g. Assigned from a pool of
|
|
|
|
addresses kept by the NAS). Other valid values indicate that the
|
|
|
|
NAS should use that value as the user's IP address.

Address
|
|
|
|
The Address format is derived from the OctetString AVP Base
|
|
|
|
Format. It is a discriminated union, representing, for example a
|
|
|
|
32-bit (IPv4) [IPV4] or 128-bit (IPv6) [IPV6] address, most
|
|
|
|
significant octet first. The first two octets of the Address
|
|
|
|
AVP represents the AddressType, which contains an Address Family
|
|
|
|
defined in [IANAADFAM]. The AddressType is used to discriminate
|
|
|
|
the content and format of the remaining octets.

own versions if they're missing from GLib (as is the case with GLib

In the code to build the list of named fields for Diameter, don't use
g_strdown(); do our own g_ascii_-style upper-case to lower-case mapping
in the hash function and use g_ascii_strcasecmp() in the compare
function.
We do this because there is no guarantee that toupper(), tolower(), and
functions that use them will, for example, map between "I" and "i" in
all locales; in Turkish locales, for example, there are, in both
upper case and lower case, versions of "i" with and without a dot, and
the upper-case version of "i" is "I"-with-a-dot and the lower-case
version of "I" is "i"-without-a-dot. This causes strings that should
match not to match.
This finishes fixing bug 2010 - an earlier checkin prevented the crash
(as there are other ways to produce the same crash, e.g. a bogus
dictionary.xml file), but didn't fix the case-insensitive string matching.

Allow a dissector to register preferences that it no longer supports as
obsolete; we silently ignore attempts to set those in a preferences
file, so that we don't spam the user with error messages caused by them
having saved preferences in an earlier release that contained those
preferences.
Make the Diameter and iSCSI dissectors register obsolete preferences.
Crash if some code tries to register a preferences module with a name
that contains something other than lower-case ASCII letters, numbers, or
underscores, or that has already been registered, or if some code tries
to register a preference with a name that contains something other than
lower-case ASCII letters, numbers, underscores, or periods, or that has
already been registered, so that we don't put code like that in a
release and have to shovel code into "prefs.c" to fix it up later. (The
problem with multiple modules or preferences with the same name should
be obvious; the problem with names with blanks, or upper-case letters,
or punctuation, is that they're a pain to type on the command line.)
