* build: restore --disable-ipv6 functionality on system w/o v6 headersOlaf Rempel2009-10-291-1/+2
| | | | | | | | | Commit 332e4acc (iptables: accept multiple IP address specifications for -s, d) broke the --disable-ipv6 configure option. > ./.libs/libxtables.so: undefined reference to `in6addr_any' Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* iprange: warn on reverse range (log)Jan Engelhardt2009-10-290-0/+0
| | | | | | | | | | | Reverse ranges like B-A cause packets to be generally never matched, as an address S does not match >=B && <=A (except for the border case where S=A=B). The kernel module itself does not check for reverse ranges, and it seems nicer to check that in userspace anyway. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* iprange: do accept non-ranges for xt_iprange v1 (log)Jan Engelhardt2009-10-250-0/+0
| | | | | | | | | | | | | | | | | Details for commit v1.4.5-11-ga10a12a: "When upgraded to new lenny kernel from 2.6.24 from etch'n'half iprange now does not allow to use single ip-address as its argument: # iptables -A FORWARD -m iprange --src-range 192.168.0.0" References: http://bugs.debian.org/547139 What we have here is that the user is now using iprange v1 from previously v0.

| | | | | | | | | | Linux systems that lack a MMU cannot call fork(). Fortunately, the only place in iptables that uses fork() follows it by an exec(), so we can easily convert the code to vfork().

* manpages: more fixes to minuses, hyphens, dashesJan Engelhardt2009-08-2016-37/+33
| | | | | | | | | | | | | | | | Debian still carries patches patches to the iptables nroff code touching ASCII minuses, so I thought, what's it this time. Eventually, this patch tries to straighten things once more, per http://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style#Hyphens and http://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style#Dashes . Titles will get the em dash; all typed commands or parameters with a hyphen get a minus (so that man(1) hyperlinking and copy-pasting does work), but other mentions get the hyphen.

* libxt_NFQUEUE: add new v1 version with queue-balance optionFlorian Westphal2009-08-203-10/+129
| | | | | | | | | | | | | | | | New version that adds support for specifying a queue range instead of a single queue id. The kernel will distribute flows across the given queue range. This is useful for multicore systems, simply start multiple instances of the userspace program on queues x, x+1, .. x+n and use "--queue-balance x:x+n". Packets belonging to the same connection are put into the same queue. With fixes from Jan Engelhardt.

* | build: build only iptables-multiJan Engelhardt2009-07-251-37/+13
| | | | | | | | | | | | | | | | | | | | | | | | I see no pressing reason to install all single programs when the multi binary can do the job. Within the build directory, developers can run the components by means of, for example, ./ip6tables-multi {main|restore|save} ... And when make install-ed, symlinks are available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changed the Makefile so that: 1. --enable-shared / --disable-shared control the linkage against libdl (and thus the potential to use 3rd party extensions) 2. --enable-static / --disable-static controls whether shipped extensions are built-in or provided as modules iptables-static becomes redundant by this action; iptables-multi now has the feature.

* | build: fix struct size mismatchJan Engelhardt2009-07-251-4/+0
| | | | | | | | | | | | | | | | | | Mixing code compiled with and without -DNO_SHARED_LIBS is fine as long as the structs have the same layout.

* | multi binary: allow subcommand via argv[1]Jan Engelhardt2009-07-252-43/+70
| | | | | | | | | | | | | | | | | | libtool does not play well with symlinks when trying to run commands in the build directory. So provide an alternate way to call iptables-multi: when argv[0] is not a recognized name, inspect [1] for an alternate identifer. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
