For WTAP_ENCAP_ERF files if we find an Extension and/or Multi-Channel header,
ensure that the size of the full pseudoheader is smaller than the packet size
to avoid an underflow and subsequent attempt to allocate a rather large amount
of memory.

form of corruption/bogosity in a file, including in a file header as
well as in records in the file. Change the error message
wtap_strerror() returns for it to reflect that.
Use it for some file header problems for which it wasn't already being
used - WTAP_ERR_UNSUPPORTED shouldn't be used for that, it should only
be used for files that we have no reason to believe are invalid but that
have a version number we don't know about or some other
non-link-layer-encapsulation-type value we don't know about.

same.
Add to wiretap/pcap-common.c a routine to fill in the pseudo-header for
ATM (by looking at the VPI, VCI, and packet data, and guessing) and
Ethernet (setting the FCS length appropriately). Use it for both pcap
and pcap-ng files.

by the gunzipping code. Have it also supply a err_info string, and
report it. Have file_error() supply an err_info string.
Put "the file" - or, for WTAP_ERR_DECOMPRESS, "the compressed file", to
suggest a decompression error - into the rawshark and tshark errors,
along the lines of what other programs print.
Fix a case in the Netscaler code where we weren't fetching the error
code on a read failure.

file_read(buf, bsize, count, file) macro is compilant with fread
function and takes elements count+ size of each element, however to make
it compilant with gzread() it always returns number of bytes.
In wiretap file_read() this is not really used, file_read is called
either with bsize set to 1 or count to 1.
Attached patch remove bsize argument from macro.

From me:
- Entry for DVBCI added to wtap.c encap_table_base[];
- Some code simplification with respect to the use of col_...() for COL_INFO;
- Certain tests for "enough bytes available" not really needed;
- (Other minor tweaks);
- #include<stdio.h> not req'd;
- Minor reformatting and whitespace cleanup;

wtap_dump_file_write(). Replace various wrappers around fwrite() with
wtap_dump_file_write(), or at least make the wrappers call
wtap_dump_file_write().

everybody use it; the places using the old wtap_dump_file_write() were
using it in the same way the old wtap_dump_file_write_all() did.
That also lets us get rid of wtap_dump_file_ferror().
Also, have the new wtap_dump_file_write() check for errors from
gzwrite() and fwrite() differently - the former returns 0 on error, the
latter can return a short write on error.

Support PPP-over-USB.
Don't remove the USB pseudo-header from the packet data for
Linux USB packets, just byte-swap it if necessary and have the
USB dissector fetch the pseudo-header from the raw packet data.
Update USB language ID values.

wtap_wtap_encap_to_pcap_encap() to wiretap/pcap-encap.h. Include it
where it's needed; don't include other Wiretap headers where they're not
needed.
Include pcapng.h in pcapng.c, to declare the functions defined in
pcapng.c. Add some casts to squelch some warnings, and add to a comment
to indicate one of the problems.

From me: Remove changes related to the ARP protocol because it doesn't
appear to be necessary for SocketCAN. Will add later if Felix says it is
needed.

Added support for Solaris IPNET layer
From me:
Some code cleanup in packet-ipnet.c
Added packet-ipnet.c to CMakeFiles.txt
Added WTAP_ENCAP_IPNET to encap_table_base[]

are any BSD/OS users still out there using Wireshark to read RFC 1483
ATM captures from BSD/OS, they can still do so, but all other users get
to read OpenBSD DLT_ENC captures, not just users *on* OpenBSD.
That also lets us simplify some hacks to deal with a link-layer type of
13 on Nokia IPSO captures.

* adds an encapsulation argument to pcap_write_phdr.
* writes the pseudo header when writing pcapng files.
This fixes a bug where you could not write pcapng files
when using encapsulations requiring pseudo headers.
svn path=/trunk/; revision=28859
* adds an encap argument to pcap_process_pseudo_header.
* adds support for reading pseudo headers.
It fixes Bug 3560.
Thanks to Tyson Key for reporting the bug and providing
trace files. This fix will be scheduled for inclusion in
Wireshark 1.2.1 and higher.

removed); we've already read the packet, and thus have already checked
it. Fixes bug 3501.

If a PCAP file containing WTAP_ENCAP_BLUETOOTH_H4_WITH_PHDR packets is saved,
it gets corrupted because the direction pseudo header isn't included.
