* Remove all storage class specifier 'register'Francois-Xavier Le Bail2017-12-131-2/+2
| | | | | | Let the compiler do the optimizations (or not) based on build options. Avoid 'value has been optimized out' messages in gdb using '-O0'.
* Replace ND_TTEST2()/ND_TCHECK2() macros by macros using pointers (1/n)Francois-Xavier Le Bail2017-12-111-2/+2
| | | | | ND_TTEST2(var, l) -> ND_TTEST_LEN(p, l) ND_TCHECK2(var, l) -> ND_TCHECK_LEN(p, l)
* Use more the EXTRACT_U_1() macro (53/n)Francois-Xavier Le Bail2017-12-101-3/+3
| | | | Assignment, p[n], (more)
* Use more the EXTRACT_U_1() macro (52/n)Francois-Xavier Le Bail2017-12-091-2/+2
| | | | Assignment, p[n]
* Use more the ND_TCHECK_1() macroFrancois-Xavier Le Bail2017-12-041-5/+5
|
* Use more the EXTRACT_U_1() macro (28/n)Francois-Xavier Le Bail2017-11-261-2/+2
| | | | | | In ND_PRINT() macro call(s) (step 7). p[n] ...
* Rename EXTRACT_ macrosFrancois-Xavier Le Bail2017-11-221-2/+2
| | | | | | | | | | | | | | | | Now all the macros have a name meaning a count in bytes. With _S_: signed, _U_: unsigned e.g.: EXTRACT_BE_32BITS -> EXTRACT_BE_U_4 EXTRACT_LE_32BITS -> EXTRACT_LE_U_4 ... EXTRACT_BE_INT32 -> EXTRACT_BE_S_4 and have: EXTRACT_8BITS -> EXTRACT_U_1 EXTRACT_INT8 -> EXTRACT_S_1
* Use pointer expressions like in most similar casesFrancois-Xavier Le Bail2017-11-201-2/+2
|
* Rename EXTRACT_nBITS() macros to EXTRACT_BE_nBITS()Francois-Xavier Le Bail2017-11-181-2/+2
| | | | | It indicates clearly that these macros are used to extract big-endian integral values.
* Move the printer summaries from INSTALL.txt to each printerFrancois-Xavier Le Bail2016-08-141-0/+2
| | | | | | | | 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
* Rename 'tcpdump-stdinc.h' to 'netdissect-stdinc.h'Francois-Xavier Le Bail2015-09-101-1/+1
| | | | Get the full log via: git log --follow netdissect-stdinc.h
* Printers must include 'netdissect.h', not 'interface.h'Francois-Xavier Le Bail2015-09-051-1/+1
|
* Fix a bunch of de-constifications.Guy Harris2015-04-261-1/+1
|
* dismiss NETDISSECT_REWORKED macroDenis Ovsienko2015-03-221-1/+0
| | | | | | | 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.
* u_intN_t is dead, long live uintN_t.Guy Harris2014-04-231-2/+2
| | | | | | | | | And, as we require at least autoconf 2.61, and as autoconf 2.61 and later have AC_TYPE_UINTn_T and AC_TYPE_INTn_T macros, we use them to define the uintN_t and intN_t macros if the system doesn't define them for us. This lets us get rid of bitypes.h as well.
* NDOize the rest of util.cDenis Ovsienko2014-04-141-1/+1
|
* Netdissectify the to-name resolution routines.Guy Harris2014-04-041-1/+1
| | | | | | | | 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.
* NDOize AODV, IPv4 and SCTP decodersDenis Ovsienko2014-03-261-1/+1
|
* NDOize VRRP decoderDenis Ovsienko2014-03-231-32/+31
|
* VRRP: top off the previous changeDenis Ovsienko2014-03-061-2/+2
| | | | Update the test cases and squelch a compiler warning.
* Add support for VRRPv3 (IPv4 only).Angus Cameron2014-03-061-7/+48
|
* remove tcpdump's own CVS keywordsDenis Ovsienko2014-01-031-5/+0
| | | | | | 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.
* Go with Wireshark's Internet checksum routine.Guy Harris2011-06-131-3/+9
| | | | | | | | | | | | | The Wireshark routine is based on the BSD in-kernel portable checksum routine (thus BSD-licensed); it takes a vector of pointers and lengths and checksums the concatenation of the buffers in question (just as the BSD in-kernel routine checksums a chain of mbufs). This simplifies the "with a pseudo-header" checksums; hopefully it'll fix up the problems being seen on some big-endian platforms, which might be due to hand-calculating some or all of the checksum and doing so incorrectly. It also gets rid of some code that might be dereferencing unaligned pointers.
* Add an "fn_printzp()" routine for printing null-padded strings (stringsguy2005-05-061-2/+5
| | | | | | | | | | | | | | | with a maximum length, where a string shorter than that length is padded with NULs), as "fn_print()" won't handle the maximum length *and* the snapshot length and "fn_printn()" won't stop on a null string. Use it where appropriate. Always pass "snapend" to "fn_print()" and "fn_printn()" if they're passed a pointer into the packet data; only pass NULL if they're being handed a pointer into a buffer that's not part of the packet data. Always check the return value of "fn_print()", "fn_printn()", and "fn_printzp()" if they're passed "snapend", and do the appropriate string termination and "packet truncated" indication if they return 1.
* Have the configure script arrange that the Makefile define _U_guy2003-11-161-4/+4
| | | | | | | | | | 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.
* From Neil Spring:guy2003-11-151-4/+4
| | | | | | | | | | | 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".
