First, check for smi.h. If we don't have it, don't check for anything
else.
If we do have it, check for libsmi containing smiInit. If we don't have
it, don't check for anything else.
If we do have it, check, with our test program, whether we can use it.
If that succeeds, prepend -lsmi to LIBS, and set USE_LIBSMI. Otherwise,
don't do either of those.
Check, in source, *only* for USE_LIBSMI. If it's set, use libsmi,
otherwise don't - don't even include smi.h, even if we happened to have
found it, and don't print the libsmi version string.

Check for pcap_set_tstamp_precision() in the configure script and, if
it's not there, don't include the code that allows time stamp precisions
to be set.

timestamps: make possible to request high precision timestamps

A while ago we introduced new API in libpcap which made possible to
request time stamps with higher precision (nanoseconds). This commit
aims to move things forward and implement missing bits. It introduces
new long option --time-stamp-precision. Note that there is no equivalent
short option.
When used for a live capture tcpdump will ask the kernel for time stamp
with desired precision and tcpdump will print fraction part of the time
stamp using respective format. We currently support only microsecond and
nanosecond precision. In the future we might support even more granular
time stamp precision, but we should be fine to support only
microseconds and nanoseconds for now. libpcap doesn't provide anything
else at the moment anyway.
When used in combination with -r/-w options then we obtain time stamps
appropriately scaled up or down from libpcap. Also note that distinct
magic number is used for savefiles containing nanosecond time stamps.

I've seen people run into situations where they were using a command like this:
tcpdump -i eth0 -G 500 -w /root/%H%M%S.pcap
The first file would be created successfully but the second file would not
because their version of tcpdump was dropping privs. It was unclear to them
that this was going on and was causing confusion.
At least with this message in there it should become more evident that
privs are being altered and aid in debugging these kinds of problems.

Also, use #defines starting at 128 (outside the ASCII range) for long
options having no short-option equivalent, and have -h/--help exit with
an exit status of 0 (you just asked for usage information, and you got
it - no fault, no error).
|
| |
|
|
| |
The new option is '--number'.

We need <errno.h> on UN*X in some files that include tcpdump-stdinc.h,
such as missing/inet_pton.c.
Remove includes of <errno.h> from files that include tcpdump-stdinc.h.

Currently, they're all aliases for existing short options, but we're out
of letters, so we'll be adding some that won't have short options.
This means we can't have entries in the options table corresponding to
short options with no long options, as an entry in the long options
table with a null option name terminates the table.
|
| |
|
|
|
|
| |
Sort the options alphabetically, and put in comments for the options
we're *currently* not using, to note that other versions of tcpdump use
them and that we should only use them for the same purposes.

That way, if we *do* have getopt_long(), we don't end up including our
getopt.h rather than the system's getopt.h.

This requires us to check for it in the configure script and to include
a version of getopt_long() for the benefit of platforms that don't have
it; we pick up the FreeBSD version and tweak it a bit (eliminating some
features specific to the BSD version of getopt_long(), as we want to use
it only in a fashion portable to Linux/*BSD/Solaris/etc.)
We also get rid of the version of getopt() we supply for Windows in
favor of the version of getopt_long() we provide.

Have them take a netdissect_options * argument, and get the "no name
resolution" flag from it.
Move the declaration of dnaddr_string to addrtoname.h, along with the
other XXX-to-string routines.

Use the header file for information about LINKTYPE_NFLOG files.
Don't build the NFLOG printer if we don't have that header file.
Fix some checks for pcap/XXX.h header files to look for
"tcpdump-stdinc.h" rather than <tcpdump-stdinc.h>, so that we don't fail
to find that header.

My wish is to put minimal code inside the getopt() switch. So I've added
a Dflag for option '-D' and a new function show_devices_and_exit().
|

Add guards to fix building against older libpcap versions (PCAP_IF_UP
and PCAP_IF_RUNNING belong to the latest libpcap only). Add a
terminating element to the array. Justify some indentation.

when -G -C is used the filename counter continued. Changed the behaviour
so that when -G is rolled over to the next file the Cflag-counter is
reset to 0 so that the filenames will restart counting.
