* We're using int8_t now, so we need to declare it ourselves if the OSguy2002-12-111-37/+75
| | | | header files don't do so for us.
* Get rid of the "-Wno-unused" flag, and fix up most of theguy2002-09-051-1/+1
| | | | | | | | | | | | | | | 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".
* Check for "pcap_version" in libpcap in the configure scripts; apparentlyguy2002-09-051-40/+154
| | | | | | | | | | the libpcap that comes with some platforms doesn't define it. Check for "pcap_debug" and "yydebug" in libpcap in the configure scripts, so that whichever one is present (which might depend on whether libpcap was built with standard YACC or Berkeley YACC/Bison), if any is present, will be used by the "-Y" flag (if none is present, "-Y" won't be supported).
* Add a few more GCC warnings on GCC >= 2 for ".devel" builds.guy2002-09-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Neil T. Spring: fixes for many of those warnings: addrtoname.c, configure.in: Linux needs netinet/ether.h for ether_ntohost print-*.c: change char *foo = "bar" to const char *foo = "bar" to appease -Wwrite-strings; should affect no run-time behavior. print-*.c: make some variables unsigned. print-bgp.c: plen ('prefix len') is unsigned, no reason to validate by comparing to zero. print-cnfp.c, print-rx.c: use intoa, provided by addrtoname, instead of inet_ntoa. print-domain.c: unsigned int l; (l=foo()) < 0 is guaranteed to be false, so check for (u_int)-1, which represents failure, explicitly. print-isakmp.c: complete initialization of attrmap objects. print-lwres.c: "if(x); print foo;" seemed much more likely to be intended to be "if(x) { print foo; }". print-smb.c: complete initialization of some structures. In addition, add some fixes for the signed vs. unsigned comparison warnings: extract.h: cast the result of the byte-extraction-and-combining, as, at least for the 16-bit version, C's integral promotions will turn "u_int16_t" into "int" if there are other "int"s nearby. print-*.c: make some more variables unsigned, or add casts to an unsigned type of signed values known not to be negative, or add casts to "int" of unsigned values known to fit in an "int", and make other changes needed to handle the aforementioned variables now being unsigned. print-isakmp.c: clean up the handling of error/status indicators in notify messages. print-ppp.c: get rid of a check that an unsigned quantity is >= 0. print-radius.c: clean up some of the bounds checking. print-smb.c: extract the word count into a "u_int" to avoid the aforementioned problems with C's integral promotions. print-snmp.c: change a check that an unsigned variable is >= 0 to a check that it's != 0. Also, fix some formats to use "%u" rather than "%d" for unsigned quantities.
* Check for "pcap_findalldevs()" in libpcap in the configuration script;guy2002-08-031-38/+93

* Fix up AC_LBL_C_INLINE to put all of the test code into the "inlines"guy2002-07-021-220/+221
| | | | | | | | | | | | section - the other section gets stuck in the middle of "main()", and, although GCC lets you define functions inside functions, other C compilers don't. Pick a name more likely to be unique to use as the iterator variable in AC_LBL_C_INLINE. Make AC_LBL_C_INLINE print "no" rather than "not supported" if inline isn't supported, to match what AC_C_INLINE does.

* From Maciej W. Rozycki <macro@ds2.pg.gda.pl>:guy2002-04-071-18/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | Here is a patch that addresses a few SSL-related issues noticed: 1. The "/usr" directory is not the best choice to start looking for SSL libraries when cross-compiling. The patch adds "/usr/${host_alias}" at the front. Actually the test is quite bogus anyway -- there might be no libcrypto.a library at all (but e.g. libcrypto.so), so a better approach would be trying to link against -lcrypto and seeing if that works. First with no additional options (it might be in the default compiler/linker's search patch, like on sane systems), then with the -L<dir> option. 2. The "cast.h" and "rc5.h" headers should include the "openssl/" path as that is what is used throughout the code. Right now they are simply not found by configure. 3. The buggy CAST128 test should use a cache variable to permit overriding by an educated user. I think I may actually rewrite the test as described in #1 above one day, but my time is quite limited and tcpdump is not my priority task, so it might not happen soon. I won't mind if someone does it earlier.

* From Maciej W. Rozycki <macro@ds2.pg.gda.pl>:guy2002-04-071-162/+210
| | | | | | | | DECnet support currently assumes certain conditions instead of checking for them explicitly. The following code checks if dnet_htoa() is available, possibly in libdnet and also verifies there is no declaration for the function in <netdnet/dnetdb.h> before it decides to provide a substitute.
* From Maciej W. Rozycki <macro@ds2.pg.gda.pl>:guy2002-04-071-177/+185
| | | | | | | An incomplete getaddrinfo bug test may prevent from cross-compiling a working IPv6 support. Caching the test's variable permits a user to override a result if he knows a given stack implementation is fine.

We should also no longer need to define __STDC__ as 2 on Digital UNIX, as we're no longer including the native OS's <netinet/ip.h> to get the layout of an IP packet declared, we're using our own "ip.h" header file for that.

Get rid of HAVE_INET_ATON, HAVE_INET_NTOP, and HAVE_INET_PTON - we don't use them; instead, we supply our own versions of "inet_aton()", "inet_ntop()", and "inet_pton()". (Defining them in "configure.in" caused complaints from "autoreconf".) Check for the "rc5.h" header, as we *do* use HAVE_RC5_H.

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.
