8a8b883450 Set the svn:eol-style property on all text files to "native", so that
they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

WTAP_ENCAP_PRISM_HEADER, WTAP_ENCAP_IEEE_802_11_WLAN_BSD, and

ba72e955dc Have "wtap_read()" set "wth->phdr.pkt_encap" to "wth->file_encap",
rather than requiring individual capture file type handlers to do it
(unless they're doing per-packet encapsulation, in which case we check
to make sure they didn't *leave* it as WTAP_ENCAP_PER_PACKET).

131be6ce7d Map WTAP_ENCAP_IEEE_802_11_WITH_RADIO to DLT_IEEE802_11, for now; we
could probably map it to one of the many different 802.11+radio headers,
but we should probably just have *one* Wiretap encapsulation for 802.11,
with a radiotap-style list of attributes attached to it.

cf131d9e16 The DLT_ value 127 is being used for the BSD radio header, and the
current CVS libpcap uses 163 for the AVS radio header (127 was never
used for the AVS radio header).  Redo the Wiretap encapsulation values
for that (and shuffle them to put the 802.11 Wiretap values together).

d6cd61061e Have the Wiretap open, read, and seek-and-read routines return, in
addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors.  Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.

Add messages for cases where those errors were returned without printing
an additional message.

Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.

Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument.  (That handles a lot of the work of putting the info
string into the error message.)

Make some variables in "ascend-grammar.y" static.

Check the return value of "erf_read_header()" in "erf_seek_read()".

Get rid of an unused #define in "i4btrace.c".

be2736adcf Have a pseudo-header for Ethernet packets, giving the size of the FCS -
0 means "there is no FCS in the packet data", 4 means "there is an FCS
in the packet data", -1 means "I don't know whether there's an FCS in
the packet data, guess based on the packet size".

Assume that Ethernet encapsulated inside other protocols has no FCS, by
having the "eth" dissector assume that (and not check for an Ethernet
pseudo-header).

Have "ethertype()" take an argument giving the FCS size; pass 0 when
appropriate.

Fix up Wiretap routines to set the pseudo-header.  This means we no
longer use the "generic" seek-and-read routine, so get rid of it.

type, and telling them how it should *NOT* be done, i.e. you should ask
tcpdump-workers for a new DLT_ value, you should not just pick a value
on your own, and you should especially not reuse a value that's already
in use!

from an "loN" device on AIX.

ad8856029b WTAP_ENCAP_ENC was, in fact, intended for use for DLT_ENC, so just
rename WTAP_ENCAP_ENC0 to WTAP_ENCAP_ENC.

un-#if 0 out the code to handle the value 109 for DLT_ENC, as I've just
checked in support for DLT_ENC in tcpdump.org libpcap and tcpdump, which
maps DLT_ENC to 109 in the file header.

8e6518ea60 In the BSDs, ARCNET packets don't have an offset field between the
addresses and the protocol type, as supplied by BPF; on Linux, they *do*
have an offset field, as supplied by PF_PACKET sockets.  Add a new
WTAP_ENCAP_ARCNET_LINUX, with packets that include the offset field, and
don't dissect an offset in WTAP_ENCAP_ARCNET packets.

Map a libpcap link-layer type of 129 to WTAP_ENCAP_ARCNET_LINUX; that
value was recently assigned to Linux-style ARCNET.

Add some more ARCNET protocol IDs.

For most protocol IDs, dissect an ATA 878.2 fragmentation header; don't
do it for RFC 1051 IP and ARP, and Diagnose packets.  Set the length of
the ARCNET protocol tree item appropriately.

Dissect both the RFC 1051 and RFC 1201 styles of IP and ARP over ARCNET,
and dissect the RFC 1201 style of RARP as well.

0a5be3f18b Rename WTAP_ENCAP_ATM_SNIFFER to WTAP_ENCAP_ATM_PDUS, as it's not just
used for the DOS-based ATM Sniffer.  (That's not a great name, but I
couldn't think of a better one.)

Add a new WTAP_ENCAP_ATM_PDUS_UNTRUNCATED encapsulation type for capture
files where reassembled frames don't have trailers, such as the AAL5
trailer, chopped off.  That's what at least some versions of the
Windows-based ATM Sniffer appear to have.

Map the ATM capture file type for NetXRay captures to
WTAP_ENCAP_ATM_PDUS_UNTRUNCATED, and put in stuff to fill in what we've
reverse-engineered, so far, for the pseudo-header; there's more that
needs to be done on it, e.g. getting the channel, AAL type, and traffic
type (or inferring them if they're not in the packet header).

2aad75bb82 Graeme Hewson noted that zlib has a bug wherein "gzseek()" doesn't set
the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.

To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.
