Kconfig help needs fixing?
Begin forwarded message: Date: Sun, 7 Aug 2005 11:25:01 -0700 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [Bugme-new] [Bug 5015] New: rp_filter documentation error in Kconfig http://bugzilla.kernel.org/show_bug.cgi?id=5015 Summary: rp_filter documentation error in Kconfig Kernel Version: 2.6 2.4 Status: NEW Severity: low Owner: [EMAIL PROTECTED] Submitter: [EMAIL PROTECTED] rp_filter is off by _kernel_ default. (Some distibutions turn it on in startup scripts). The folowing text from net/ipv4/Kconfig is confusing.(It seems one distribution maintainer thinks rp_filter is on by kernel default) "config IP_ADVANCED_ROUTER [..........] If you turn on IP forwarding, you will also get the rp_filter, which automatically rejects incoming packets if the routing table entry for their source address doesn't match the network interface they're arriving on. This has security advantages because it prevents the so-called IP spoofing, however it can pose problems if you use asymmetric routing (packets from you to a host take a different path than packets from that host to you) or if you operate a non-routing host which has several IP addresses on different interfaces. To turn rp_filter off use: echo 0 > /proc/sys/net/ipv4/conf/<device>/rp_filter or echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter" In 2.4 the error is in Documentation/Configure/help. Please fix this too.
