some sscanf() calls:
The first change involves a sscanf() that has '%n' in the format
string, which shouldn't be checked for in the return value
(stored in "ntok"). This is done correctly elsewhere in the code
(and even commented on) such that the return value is checked for
everything but the %n modifier.
And a few lines after this, a sscanf() is done for '%d' and the
return value is stored in "ret". However, the same exact line
from the above mishap is used here, not even checking the right
variable or number of conversions! It checks "ntok" for 2 when
it should check "ret" for 1.
Changing the behaviour when the ERF type is unknown, and for ERF
TYPE_PAD.
Unknown ERF types can always be captured as DLT_ERF. TYPE_PAD
records are dropped silently.
payload, the existing value of that offset is *not* in the X register -
the offset of the MAC header is in the X register. Load the register
containing the offset of the MAC payload, add 2 to it, and store the
result back in that register.
802.11 headers - we only handle the QoS bit and fields, for now.
Clean up various other things either in the process of doing that or as
a requirement for doing that.
before compiling an expression; pcap_compile() can be called more than
once, and some registers can now be allocated and not freed in the
process of code generation (for example, the register allocated to hold
the length of a radiotap header, which can't be freed until we're
finished generating all the code).
field in a capture file into:
a 16-bit link-layer type field (it's 16 bits in pcap-NG, and
that'll probably be enough for the foreseeable future);
a 10-bit "class" field, indicating the group of link-layer type
values to which the link-layer type belongs - class 0 is for
regular DLT_ values, and class 0x224 grandfathers in the NetBSD
"raw address family" link-layer types;
a 6-bit "extension" field, storing information about the
capture, such an indication of whether the packets include an
FCS and, if so, how many bytes of FCS are present.
Fix the copyright notice.
Use the new DLT_BLUETOOTH_HCI_H4_WITH_PHDR DLT, and add a
direction indication.
Now that we have a direction indication, support
pcap_setdirection().
Update FILES and INSTALL.txt appropriately, and fix some problems in
INSTALL.txt.
Add support for additional link types to gencode.c, so we at least
support "link[N:M]" and an empty expression.
Sort the DLT_CHOICE values in order by the DLT_ value, add missing ones,
and fix some existing descriptions.
