2015-06-25Clean up 802.11 radio information handling.Guy Harris1-0/+1
Have a field that holds the PHY type but nothing else. Have a union with structures holding PHY-type-specific information, as a bunch of attributes are PHY-specific. If we have a channel and band, but don't have the frequency, attempt to calculate the frequency, and add that to the radio information if we succeed. If we have the frequency, but don't have the channel, attempt to calculate the channel, and add that to the radio information if we succeed. Handle FHSS information, 11a "half/quarter-clocked" and turbo information, 11g normal vs. Super G, additional 11n and 11ac information, and the "short preamble" flag for 11b and 11g. Add a PHY type for 11 legacy DSSS and detect it if possible. Clean up the AVS dissector - make all fields wlancap. fields (if you want generic fields, use the wlan_radio. fields). Set more fields when writing out Commview Wi-Fi files.

2015-06-20Call the "802.11 radio information" dissector for radio headers.Guy Harris1-3/+12
Have dissectors of various forms of radio information headers in the packets fill in a struct ieee_802_11_phdr with radio information as appropriate, and call the "802.11 radio information" dissector rather than the raw 802.11 dissector. This means that the radio information can be found in a protocol-independent and encapsulation-independent form when you're looking at the packet; that information can be presented in a form somewhat easier to read than the raw metadata header format. It also enables having a single "radio information" tap that allows statistics to handle all different sorts of radio information encapsulation. In addition, it lets us clean up some of the arguments passed to the common 802.11 dissector routine, by having it pull that information from the struct ieee_802_11_phdr. Ensure that the right structure gets passed to that routine, and that all the appropriate parts of that structure are filled in. Rename the 802.11 radio protocol to "wlan_radio", rather than just "radio", as it's 802.11-specific. Give all its fields "wlan_radio." names rather than "wlan." names.

Specifically: - Set packet.h to be the first wireshark #include after config.h and "system" #includes. packet.h added as an #include in some cases when missing. - Remove some #includes included (directly/indirectly) in packet.h. E.g., glib.h.

2014-05-29Introduce 802.11 dissectors with wired-in "FCS present" indications.Guy Harris1-1/+1
For a number of protocols that encapsulate 802.11 frames inside packets, whether the frame includes an FCS or not is specified by the protocol, not by whether the link-layer frame carrying the packets *itself* includes an FCS. As we've done with Ethernet, add "_withfcs" and "_withoutfcs" dissectors, which *don't* check the pseudo-header FCS length indication, and call those, rather than dissectors that check the pseudo-header length indication, from the dissectors for those protocols.

svn path=/trunk/; revision=53230
2013-02-27Move show_exception() and show_reported_bounds_error() toGuy Harris1-8/+3
epan/show_exception.c, as it's used outside epan/dissectors/packet-frame.c. Update their callers to include <epan/show_exception.h> to get their declaration. Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if there's more stuff in the packet to dissect after the dissector call that threw the exception, doesn't mean you shouldn't go ahead and dissect that stuff. Use it in all those cases, including ones where BoundsError was inappropriately being caught (you want those passed up to the top level, so that the packet is reported as having been cut short in the capture process). Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that correspond to running past the end of the data for a tvbuff; use it rather than explicitly catching those exceptions individually, and rather than just catching all exceptions (the only place that DissectorError should be caught, for example, is at the top level, so dissector bugs show up in the protocol tree). Don't catch and then immediately rethrow exceptions without doing anything else; just let the exceptions go up to the final catcher. Use show_exception() to report non-fatal errors, rather than doing it yourself. If a dissector is called from Lua, catch all non-fatal errors and use show_exception() to report them rather than catching only ReportedBoundsError and adding a proto_malformed item. Don't catch exceptions when constructing a trailer tvbuff in packet-ieee8023.c - just construct it after the payload has been dissected, and let whatever exceptions that throws be handled at the top level. Avoid some TRY/CATCH/ENDTRY cases by using checks such as tvb_bytes_exist() before even looking in the tvbuff. svn path=/trunk/; revision=47924
