Introduce, and start using, TVB_SET_ADDRESS() and TVB_SET_ADDRESS_HF(). They
are like the non-TVB versions except that they take a TVB and an offset
instead of (frequently) a pointer into the TVB.
Calling tvb_get_ptr() before modifying the rest of the fields should help fix
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7960 (though I can't
reproduce that problem).
Replace a bunch of calls like:
SET_ADDRESS(..., AT_XXX, length, tvb_get_ptr(tvb, offset, length));
with:
TVB_SET_ADDRESS(..., AT_XXX, tvb, offset, length);

Introduce, and start using, TVB_SET_ADDRESS() and TVB_SET_ADDRESS_HF(). They
are like the non-TVB versions except that they take a TVB and an offset
instead of (frequently) a pointer into the TVB.
Calling tvb_get_ptr() before modifying the rest of the fields should help fix
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7960 (though I can't
reproduce that problem).
Replace a bunch of calls like:
SET_ADDRESS(..., AT_XXX, length, tvb_get_ptr(tvb, offset, length));
with:
TVB_SET_ADDRESS(..., AT_XXX, tvb, offset, length);
