2007-03-25[NET]: Fix fib_rules compatibility breakageThomas Graf
Based upon a patch from Patrick McHardy. The fib_rules netlink attribute policy introduced in 2.6.19 broke userspace compatibilty. When specifying a rule with "from all" or "to all", iproute adds a zero byte long netlink attribute, but the policy requires all addresses to have a size equal to sizeof(struct in_addr)/sizeof(struct in6_addr), resulting in a validation error. Check attribute length of FRA_SRC/FRA_DST in the generic framework by letting the family specific rules implementation provide the length of an address. Report an error if address length is non zero but no address attribute is provided. Fix actual bug by checking address length for non-zero instead of relying on availability of attribute.

2006-12-02[IPv6] rules: Remove bogus tos validation checkThomas Graf
Noticed by Al Viro: (frh->tos & ~IPV6_FLOWINFO_MASK)) where IPV6_FLOWINFO_MASK is htonl(0xfffffff) and frh->tos is u8, which makes no sense here... Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-02[NETLINK]: Do precise netlink message allocations where possibleThomas Graf
Account for the netlink message header size directly in nlmsg_new() instead of relying on the caller calculate it correctly. Replaces error handling of message construction functions when constructing notifications with bug traps since a failure implies a bug in calculating the size of the skb.

2006-12-02[NET] rules: Share common attribute validation policyThomas Graf
Move the attribute policy for the non-specific attributes into net/fib_rules.h and include it in the respective protocols. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-12-02[NET]: Rethink mark field in struct flowiThomas Graf
Now that all protocols have been made aware of the mark field it can be moved out of the union thus simplyfing its usage. The config options in the IPv4/IPv6/DECnet subsystems to enable respectively disable mark based routing only obfuscate the code with ifdefs, the cost for the additional comparison in the flow key is insignificant, and most distributions have all these options enabled by default anyway. Therefore it makes sense to remove the config options and enable mark based routing by default. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-10-15[IPv6] rules: Use RT6_LOOKUP_F_HAS_SADDR and fix source based selectorsThomas Graf
Fixes rt6_lookup() to provide the source address in the flow and sets RT6_LOOKUP_F_HAS_SADDR whenever it is present in the flow. Avoids unnecessary prefix comparisons by checking for a prefix length first. Fixes the rule logic to not match packets if a source selector has been specified but no source address is available.

2006-09-22[IPV6]: Fix routing by fwmarkPatrick McHardy
Fix mark comparison, also dump the mask to userspace when the mask is zero, but the mark is not (in which case the mark is dumped, so the mask is needed to make sense of it). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-09-22[NET]: Introduce RTA_TABLE/FRA_TABLE attributesPatrick McHardy
Introduce RTA_TABLE route attribute and FRA_TABLE routing rule attribute to hold 32 bit routing table IDs. Usespace compatibility is provided by continuing to accept and send the rtm_table field, but because of its limited size it can only carry the low 8 bits of the table ID. This implies that if larger IDs are used, _all_ userspace programs using them need to use RTA_TABLE. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2006-09-22[IPV6]: Make sure fib6_rule_lookup doesn't return NULLVille Nuorvala
