with the tag '\summary:' for greping.
Remark: Currently some printers have no summary line.
Moreover:
Summarize all printers with a single line in INSTALL.txt
The purpose of this macro was to enable the file-by-file switch to NDO,
after which only tcpdump.c had a use of it and the definitions guarded
by it. Update tcpdump.c not to require them any more and dismiss the
unused definitions.
Always define and declare ip6_print(), always compile print-ip6.c, and
always call it if we recognize a payload as IPv6. If INET6 isn't
defined, ip6_print() will just print the length and note that printing
isn't supported.
That way, we don't do weird dissection of IPv6 packets on systems
without IPv6 support, due to, for example, ethertype_print() returning 0
("not dissected") for IPv6 packets on those systems (IPv6-over-Frame
Relay was dissected weirdly due to this).
Both interface.h and netdissect.h include <pcap.h>, thus most files
should not include it regardless if these need it or not. The only
exceptions so far remain:
* addrtoname.c
* missing/datalinks.c
* missing/dlnames.c
* tcpdump.c
Remove lots of $Header's and a few $Id's that all belong to the former
CVS repository of tcpdump itself. These keywords have been frozen since
the migration to git in late 2008.
For headers included in only one source file, put the header contents in
the source file in question, and get rid of a bunch of stuff from the
header not used in the source file.
For each decoder that has more than one instance of truncation signaling
and prints the same string in each instance make sure that the string is
declared as "static const char tstr[]" right after the initial includes
block. Where necessary, replace fputs(s, stdout) with equivalent
printf("%s", s).
appropriately, and that GNUmakefile and the MSVC++ project file define
it apppriately, as we do with libpcap, rather than defining it in
"interface.h".
Undo the rcsid-shuffling and addition of extra #includes, as we no
longer need to arrange that "interface.h" be included before using _U_
in an RCS ID or copyright.
use "_U_" in the definitions of "rcsid[]", to eliminate
complaints about those variables being unused;
move the definitions after the include of "interface.h", or add
an include of "interface.h", so that "_U_" is defined.
Include "config.h" before including "tcpdump-stdinc.h" in
"missing/datalinks.c".
tcpdump.c. Have if_print routines return the length of the link-layer
header, so that the common code knows how to skip the link-layer header
when printing the packet in hex/ASCII.
beginning of the raw packet data, the captured length of the raw packet
data, and the length of the link-layer header, and:
if "-e" was specified, prints all the raw packet data;
if "-e" was not specified, prints all the raw packet data past
the link-layer header, if there is any.
Use that routine in all the "xxx_if_print()" routines if "-x" was
specified.
Make "arcnet_encap_print()" static - it's not used outside
"print-arcnet.c".
Add missing info printing code to "atm_if_print()".
Print the packet data in "lane_if_print()", not in "lane_print()", as
"lane_print()" can be called from other "xxx_if_print()" routines, and
those routines will also print the packet data if "-x" was specified -
no need to print it twice.
dissector really needs source and destination MAC addresses, we should
make global pointers to them - which would be null for packets lacking
MAC addresses, so dissectors that need them will need to do something
sensible if those pointers are null.)
Don't fake up an Ethernet header if there aren't any MAC addresses to
use when faking it up.
"bp_chaddr" in "print-bootp.c" is an array, so "bp->bp_chaddr" cannot be
null, and there's no need to test for it not being null.
unused-parameter problems reported by GCC. Add an _U_ tag to label
parameters as unused if the function is called through a pointer (so
that you can't change its signature by removing parameters) or if there
are unused parameters only because the function isn't complete.
Add some additional bounds checks the necessity for which was revealed
while cleaning up unused-parameter problems.
Make some routines static.
"lcp_print()", defined in "print-lcp.c", isn't called anywhere -
"print-ppp.c" has the code to dissect LCP. Get rid of "print-lcp.c".
Split the Cisco HDLC printer into "chdlc_if_print()", which does the
stuff expected of a low-level print routine (printing the time stamp,
printing the final newline, doing the infodelay stuff) and
"chdlc_print()", which doesn't do that stuff. This lets us clean up
"ppp_hdlc_if_print()" a bit - it can just print the time stamp at the
beginning, and do the infodelay stuff at the end, without having to
treat Cisco HDLC specially by skipping the time stamp printing. (This
also ensures that the time stamp is always printed, which wasn't the
case before.)
Print the missing final newline in "pppoe_if_print()".
the top-level directory, remove from them all stuff not needed by
tcpdump, include them rather than the system's header files, and get rid
of assorted unnecessary include files.
This means you don't need to check for "slip.h" when building
"print-sl.c", stubbing it out on systems that don't have "slip.h". We
also don't need to build the stuff in "print-vjc.c" only on BSD/OS.
Use "u_int32_t" and "u_int16_t" rather than "u_int" and "u_short" for
structure members in "print-chdlc.c".
Move PPP_HDRLEN from "print-ppp.c" to "ppp.h", as per the XXX comment in
"print-ppp.c".
have dissectors include them rather than <netinet/ip.h> or
<netinet/ip_var.h>, if they actually need that stuff.
Put the declarations of the ICMP stuff directly into "print-icmp.c".
Remove all unnecessary includes of <netinet/ip*.h> files.
Copy the byte-order stuff from "nameser.h" into "tcp.h".
by dissectors, and have dissectors include them rather than
<netinet/udp.h>, <netinet/udp_var.h>, or <netinet/tcp.h>, if they
actually need that stuff.
Remove all unnecessary includes of <netinet/udp*.h> or <netinet/tcp*.h>
files.
"linux-includes/netinet/if_ether.h" to "ethertype.h".
Move other stuff used by dissectors from <netinet/if_ether.h> to
"ether.h", along the lines of "fddi.h" and "token.h".
Move ARP declarations from BSD include files to "print-arp.c".
Remove from dissectors includes of <netinet/if_ether.h>, and add
includes of "ethertype.h" and/or "ether.h" as necessary.
Get rid of configuration options that test declarations now made in
"ether.h" or "print-arp.c", as those declarations are now under our
control, not the OS's control.
