* [IPV6]: fix BUG of ndisc_send_redirect()Li Yewang2007-01-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I tested IPv6 redirect function about kernel 2.6.19.1, and found that the kernel can send redirect packets whose target address is global address, and the target is not the actual endpoint of communication. But the criteria conform to RFC2461, the target address defines as following: Target Address An IP address that is a better first hop to use for he ICMP Destination Address. When the target is the actual endpoint of communication, i.e., the destination is a neighbor, the Target Address field MUST contain the same value as the ICMP Destination Address field. Otherwise the target is a better first-hop router and the Target Address MUST be the router's link-local address so that hosts can uniquely identify routers. According to this definition, when a router redirect to a host, the target address either the better first-hop router's link-local address or the same as the ICMP destination address field. But the function of ndisc_send_redirect() in net/ipv6/ndisc.c, does not check the target address correctly. There is another definition about receive Redirect message in RFC2461: 8.1. Validation of Redirect Messages A host MUST silently discard any received Redirect message that does not satisfy all of the following validity checks: ...... - The ICMP Target Address is either a link-local address (when redirected to a router) or the same as the ICMP Destination Address (when redirected to the on-link destination). ...... And the receive redirect function of ndisc_redirect_rcv() implemented this definition, checks the target address correctly. if (ipv6_addr_equal(dest, target)) { on_link = 1; } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) { ND_PRINTK2(KERN_WARNING "ICMPv6 Redirect: target address is not link-local.\n"); return; } So, I think the send redirect function must check the target address also.

* [NETFILTER]: nf_conntrack_ipv6: fix crash when handling fragmentsPatrick McHardy2007-01-091-0/+2
| | | | | | | | | | | When IPv6 connection tracking splits up a defragmented packet into its original fragments, the packets are taken from a list and are passed to the network stack with skb->next still set. This causes dev_hard_start_xmit to treat them as GSO fragments, resulting in a use after free when connection tracking handles the next fragment.

* [INET]: Fix incorrect "inet_sock->is_icsk" assignment.Paul Moore2007-01-091-1/+1
| | | | | | | | | | | The inet_create() and inet6_create() functions incorrectly set the inet_sock->is_icsk field. Both functions assume that the is_icsk field is large enough to hold at least a INET_PROTOSW_ICSK value when it is actually only a single bit. This patch corrects the assignment by doing a boolean comparison whose result will safely fit into a single bit field. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 590bdf7fd2292b47c428111cb1360e312eff207e introduced a regression in match/target hook validation. mark_source_chains builds a bitmask for each rule representing the hooks it can be reached from, which is then used by the matches and targets to make sure they are only called from valid hooks. The patch moved the match/target specific validation before the mark_source_chains call, at which point the mask is always zero. This patch returns back to the old order and moves the standard checks to mark_source_chains. This allows to get rid of a special case for standard targets as a nice side-effect.

(Note that free_percpu is #defined as percpu_free in include/linux/percpu.h.) A few callers are updated to remove now-unneeded tests for NULL. A few other callers already seem to assume that passing a NULL pointer to percpu_free() is okay! The patch also removes an unnecessary NULL check in percpu_depopulate().

Currently we have two (unsupported by userspace) hacks in the LOG and ULOG targets to optionally call to the nflog API.

* [UDP(-Lite)]: consolidate v4 and v6 get|setsockopt codeGerrit Renker2006-12-021-109/+9
| | | | | | | | | | | | | | | | | | | | | | | This patch consolidates set/getsockopt code between UDP(-Lite) v4 and 6. The justification is that UDP(-Lite) is a transport-layer protocol and therefore the socket option code (at least in theory) should be AF-independent. Furthermore, there is the following code reduplication: * do_udp{,v6}_getsockopt is 100% identical between v4 and v6 * do_udp{,v6}_setsockopt is identical up to the following differerence --v4 in contrast to v4 additionally allows the experimental encapsulation types UDP_ENCAP_ESPINUDP and UDP_ENCAP_ESPINUDP_NON_IKE --the remainder is identical between v4 and v6 I believe that this difference is of little relevance. The advantages in not duplicating twice almost completely identical code. The patch further simplifies the interface of udp{,v6}_push_pending_frames, since for the second argument (struct udp_sock *up) it always holds that up = udp_sk(sk); where sk is the first function argument.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a revision of the previously submitted patch, which alters the way files are organized and compiled in the following manner: * UDP and UDP-Lite now use separate object files * source file dependencies resolved via header files net/ipv{4,6}/udp_impl.h * order of inclusion files in udp.c/udplite.c adapted accordingly [NET/IPv4]: Support for the UDP-Lite protocol (RFC 3828) This patch adds support for UDP-Lite to the IPv4 stack, provided as an extension to the existing UDPv4 code: * generic routines are all located in net/ipv4/udp.c * UDP-Lite specific routines are in net/ipv4/udplite.c * MIB/statistics support in /proc/net/snmp and /proc/net/udplite * shared API with extensions for partial checksum coverage [NET/IPv6]: Extension for UDP-Lite over IPv6 It extends the existing UDPv6 code base with support for UDP-Lite in the same manner as per UDPv4. In particular, * UDPv6 generic and shared code is in net/ipv6/udp.c * UDP-Litev6 specific extensions are in net/ipv6/udplite.c * MIB/statistics support in /proc/net/snmp6 and /proc/net/udplite6 * support for IPV6_ADDRFORM * aligned the coding style of protocol initialisation with af_inet6.c * made the error handling in udpv6_queue_rcv_skb consistent; to return `-1' on error on all error cases * consolidation of shared code [NET]: UDP-Lite Documentation and basic XFRM/Netfilter support The UDP-Lite patch further provides * API documentation for UDP-Lite * basic xfrm support * basic netfilter support for IPv4 and IPv6 (LOG target) Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.
