* [NET]: Make the device list and device lookups per namespace.Eric W. Biederman2007-10-1099-362/+555
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]: Support multiple network namespaces with netlinkEric W. Biederman2007-10-1022-60/+121
| | | | | | | | | | | | | | | | | | | | | Each netlink socket will live in exactly one network namespace, this includes the controlling kernel sockets. This patch updates all of the existing netlink protocols to only support the initial network namespace. Request by clients in other namespaces will get -ECONREFUSED. As they would if the kernel did not have the support for that netlink protocol compiled in. As each netlink protocol is updated to be multiple network namespace safe it can register multiple kernel sockets to acquire a presence in the rest of the network namespaces. The implementation in af_netlink is a simple filter implementation at hash table insertion and hash table look up time. Signed-off-by: Eric W.

* [NET]: Make device event notification network namespace safeEric W. Biederman2007-10-1038-1/+126
| | | | | | | | | | | | | | | | | | 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 packet reception network namespace safeEric W. Biederman2007-10-1026-0/+113
| | | | | | | | | | | | | | This patch modifies every packet receive function registered with dev_add_pack() to drop packets if they are not from the initial network namespace. This should ensure that the various network stacks do not receive packets in a anything but the initial network namespace until the code has been converted and is ready for them.

* [NET]: Initialize the network namespace of network devices.Eric W. Biederman2007-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | Except for carefully selected pseudo devices all network interfaces should start out in the initial network namespace. Ultimately it will be register_netdev that examines what dev->nd_net is set to and places a device in a network namespace. This patch modifies alloc_netdev to initialize the network namespace a device is in with the initial network namespace. This gets it right for the vast majority of devices so their drivers need not be modified and for those few pseudo devices that need something different they can change this parameter before calling register_netdevice. The network namespace parameter on a network device is not reference counted as the devices are inside of a network namespace and cannot remain in that namespace past the lifetime of the network namespace.

* [NET]: Make socket creation namespace safe.Eric W. Biederman2007-10-1044-113/+184
| | | | | | | | | | | | | | | | | | | | | | | This patch passes in the namespace a new socket should be created in and has the socket code do the appropriate reference counting. By virtue of this all socket create methods are touched. In addition the socket create methods are modified so that they will fail if you attempt to create a socket in a non-default network namespace. Failing if we attempt to create a socket outside of the default network namespace ensures that as we incrementally make the network stack network namespace aware we will not export functionality that someone has not audited and made certain is network namespace safe. Allowing us to partially enable network namespaces before all of the exotic protocols are supported. Any protocol layers I have missed will fail to compile because I now pass an extra parameter into the socket creation code.

* [NET]: Make /proc/net per network namespaceEric W. Biederman2007-10-1084-261/+342
| | | | | | | | | | | | | | | | | | This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

* [NET]: Basic network namespace infrastructure.Eric W. Biederman2007-10-103-1/+361
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the basic infrastructure needed to support network namespaces. This infrastructure is: - Registration functions to support initializing per network namespace data when a network namespaces is created or destroyed. - struct net. The network namespace data structure. This structure will grow as variables are made per network namespace but this is the minimal starting point. - Functions to grab a reference to the network namespace. I provide both get/put functions that keep a network namespace from being freed. And hold/release functions serve as weak references and will warn if their count is not zero when the data structure is freed. Useful for dealing with more complicated data structures like the ipv4 route cache. - A list of all of the network namespaces so we can iterate over them. - A slab for the network namespace data structure allowing leaks to be spotted.

So far, the only audit calls made are when add/delete an SA/policy. It had been discussed to give each key manager it's own calls to do this, but I found there to be much redundnacy since they did the exact same things, except for how they got auid and sid, so I combined them.

* [AF_PACKET]: Don't enable global timestamps.Stephen Hemminger2007-10-101-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Andi mentioned he did something like this already, but never submitted it. The dhcp client application uses AF_PACKET with a packet filter to receive data. The application doesn't even use timestamps, but because the AF_PACKET API has timestamps, they get turned on globally which causes an expensive time of day lookup for every packet received on any system that uses the standard DHCP client. The fix is to not enable the timestamp (but use if if available). This causes the time lookup to only occur on those packets that are destined for the AF_PACKET socket. The timestamping occurs after packet filtering so all packets dropped by filtering to not cause a clock call. The one downside of this a a few microseconds additional delay added from the normal timestamping location (netif_rx) until the receive callback in AF_PACKET. But since the offset is fairly consistent it should not upset applications that do want really use timestamps, like wireshark.

* [MAC80211]: rework key handlingJohannes Berg2007-10-1012-229/+366
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves all the key handling code out from ieee80211_ioctl.c into key.c and also does the following changes including documentation updates in mac80211.h: 1) Turn off hardware acceleration for keys when the interface is down. This is necessary because otherwise monitor interfaces could be decrypting frames for other interfaces that are down at the moment. Also, it should go some way towards better suspend/resume support, in any case the routines used here could be used for that as well. Additionally, this makes the driver interface nicer, keys for a specific local MAC address are only ever present while an interface with that MAC address is enabled. 2) Change driver set_key() callback interface to allow only return values of -ENOSPC, -EOPNOTSUPP and 0, warn on all other return values. This allows debugging the stack when a driver notices it's handed a key while it is down. 3) Invert the flag meaning to KEY_FLAG_UPLOADED_TO_HARDWARE. 4) Remove REMOVE_ALL_KEYS command as it isn't used nor do we want to use it, we'll use DISABLE_KEY for each key. It is hard to use REMOVE_ALL_KEYS because we can handle multiple virtual interfaces with different key configuration, so we'd have to keep track of a lot of state for this and that isn't worth it. 5) Warn when disabling a key fails, it musn't. 6) Remove IEEE80211_HW_NO_TKIP_WMM_HWACCEL in favour of per-key IEEE80211_KEY_FLAG_WMM_STA to let driver sort it out itself. 7) Tell driver that a (non-WEP) key is used only for transmission by using an all-zeroes station MAC address when configuring. 8) Change the set_key() callback to have access to the local MAC address the key is being added for.

* [MAC80211]: embed key conf in key, fix driver interfaceJohannes Berg2007-10-1015-205/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch embeds the struct ieee80211_key_conf into struct ieee80211_key and thus avoids allocations and having data present twice. This required some more changes: 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag. This flag isn't used by drivers nor should it be since we have a set_key_idx() callback. Maybe that callback needs to be extended to include the key conf, but only a driver that requires it will tell. 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag. This flag is global, so it shouldn't be passed in the key conf structure. Pass it to the function instead. Also, this patch removes the AID parameter to the set_key() callback because it is currently unused and the hardware currently cannot know about the AID anyway. I suspect this was used with some hardware that actually selected the AID itself, but that functionality was removed. Additionally, I've removed the ALG_NULL key algorithm since we have ALG_NONE.

* [MAC80211]: fix software decryptionJohannes Berg2007-10-103-54/+103
| | | | | | | | | | | | | | | | | | | | | | | | | When doing key selection for software decryption, mac80211 gets a few things wrong: it always uses pairwise keys if configured, even if the frame is addressed to a multicast address. Also, it doesn't allow using a key index of zero if a pairwise key has also been found. This patch changes the key selection code to be (more) in line with the 802.11 specification. I have confirmed that with this, multicast frames are correctly decrypted and I've tested with WEP as well. While at it, I've cleaned up the semantics of the hardware flags IEEE80211_HW_WEP_INCLUDE_IV and IEEE80211_HW_DEVICE_HIDES_WEP and clarified them in the mac80211.h header; it is also now allowed to set the IEEE80211_HW_DEVICE_HIDES_WEP option even if it only applies to frames that have been decrypted by the hw, unencrypted frames must be dropped but encrypted frames that the hardware couldn't handle can be passed up unmodified.
