[NET]: Make device event notification network namespace safe Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>

[NET]: Make the device list and device lookups per namespace. This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

[NET] fib_rules: Flush route cache after rule modifications The results of FIB rules lookups are cached in the routing cache except for IPv6 as no such cache exists. So far, it was the responsibility of the user to flush the cache after modifying any rules. This lead to many false bug reports due to misunderstanding of this concept. This patch automatically flushes the route cache after inserting or deleting a rule. Thanks to Muli Ben-Yehuda <muli@il.ibm.com> for catching a bug in the previous patch.

[NET] fib_rules: goto rule action This patch adds a new rule action FR_ACT_GOTO which allows to skip a set of rules by jumping to another rule. The rule to jump to is specified via the FRA_GOTO attribute which carries a rule preference. Referring to a rule which doesn't exists is explicitely allowed. Such goto rules are marked with the flag FIB_RULE_UNRESOLVED and will act like a rule with a non-matching selector. The rule will become functional as soon as its target is present. The goto action enables performance optimizations by reducing the average number of rules that have to be passed per lookup. Example: 0: from all lookup local 40: not from all to 192.168.23.128 goto 32766 41: from all fwmark 0xa blackhole 42: from all fwmark 0xff blackhole 32766: from all lookup main Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

[NET]: Change "not found" return value for rule lookup This changes the "not found" error return for the lookup function to -ESRCH so that it can be distinguished from the case where a rule or route resulting in -ENETUNREACH has been found during the search.

[NET]: Fix fib_rules compatibility breakage 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.

[NET] fib_rules: Flush route cache after rule modifications The results of FIB rules lookups are cached in the routing cache except for IPv6 as no such cache exists. So far, it was the responsibility of the user to flush the cache after modifying any rules. This lead to many false bug reports due to misunderstanding of this concept. This patch automatically flushes the route cache after inserting or deleting a rule. Thanks to Muli Ben-Yehuda <muli@il.ibm.com> for catching a bug in the previous patch.

[NET] fib_rules: goto rule action This patch adds a new rule action FR_ACT_GOTO which allows to skip a set of rules by jumping to another rule. The rule to jump to is specified via the FRA_GOTO attribute which carries a rule preference. Referring to a rule which doesn't exists is explicitely allowed. Such goto rules are marked with the flag FIB_RULE_UNRESOLVED and will act like a rule with a non-matching selector. The rule will become functional as soon as its target is present. The goto action enables performance optimizations by reducing the average number of rules that have to be passed per lookup. Example: 0: from all lookup local 40: not from all to 192.168.23.128 goto 32766 41: from all fwmark 0xa blackhole 42: from all fwmark 0xff blackhole 32766: from all lookup main Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

[NET]: Fix fib_rules compatibility breakage 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.

[NET]: Make device event notification network namespace safe Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>

[IPV4/IPV6/DECNET]: Small cleanup for fib rules. This patch slightly cleanups FIB rules framework. rules_list as a pointer on struct fib_rules_ops is useless.
