| * cfg80211: add rfkill supportJohannes Berg2009-06-033-7/+44
| | | | | | | | | | | | | | | | | | | | | | To be easier on drivers and users, have cfg80211 register an rfkill structure that drivers can access. When soft-killed, simply take down all interfaces; when hard-killed the driver needs to notify us and we will take down the interfaces after the fact. While rfkilled, interfaces cannot be set UP.

| * rfkill: add function to query stateJohannes Berg2009-06-031-0/+12
| | | | | | | | | | | | | | | | | | | | | | Sometimes it is necessary to know how the state is, and it is easier to query rfkill than keep track of it somewhere else, so add a function for that. This could later be expanded to return hard/soft block, but so far that isn't necessary. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * rfkill: create useful userspace interfaceJohannes Berg2009-06-031-24/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new code added by this patch will make rfkill create a misc character device /dev/rfkill that userspace can use to control rfkill soft blocks and get status of devices as well as events when the status changes. Using it is very simple -- when you open it you can read a number of times to get the initial state, and every further read blocks (you can poll) on getting the next event from the kernel. The same structure you read is also used when writing to it to change the soft block of a given device, all devices of a given type, or all devices. This also makes CONFIG_RFKILL_INPUT selectable again in order to be able to test without it present since its functionality can now be replaced by userspace entirely and distros and users may not want the input part of rfkill interfering with their userspace code. We will also write a userspace daemon to handle all that and consequently add the input code to the feature removal schedule. In order to have rfkilld support both kernels with and without CONFIG_RFKILL_INPUT (or new kernels after its eventual removal) we also add an ioctl (that only exists if rfkill-input is present) to disable rfkill-input. It is not very efficient, but at least gives the correct behaviour in all cases.

* | gso: Stop fraglists from escapingHerbert Xu2009-06-031-3/+2
|/ | | | | | | | | | | | | | | | | | | | As it stands skb fraglists can get past the check in dev_queue_xmit if the skb is marked as GSO. In particular, if the packet doesn't have the proper checksums for GSO, but can otherwise be handled by the underlying device, we will not perform the fraglist check on it at all. If the underlying device cannot handle fraglists, then this will break. The fix is as simple as moving the fraglist check from the device check into skb_gso_ok. This has caused crashes with Xen when used together with GRO which can generate GSO packets with fraglists. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

Thus the conntrack entry is destroyed but the destination retransmits data until timeout. The same technique, i.e. sending properly crafted RST segments, can easily be used to bypass connlimit/connbytes based restrictions (the sample script written by Robert can be found in the netfilter mailing list archives). The patch below adds a new flag and new field to struct ip_ct_tcp_state so that checking RST segments can be made more strict and thus TCP conntrack can catch the invalid ones: the RST segment is accepted only if its sequence number higher than or equal to the highest ack we seen from the other direction. (The last_ack field cannot be reused because it is used to catch resent packets.) Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

This patch provides a new socket option IP_MULTICAST_ALL. In this case, default behaviour is _unchanged_ from the current Linux standard. The socket option is set by default to provide original behaviour. Sockets wishing to receive data only from multicast groups they join explicitly will need to clear this socket option.

It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.

In every mode, bonding interface uses the same mac address for all enslaved devices (except fail_over_mac). Only balance-alb will simultaneously use multiple MAC addresses across different slaves. When you put this kind of bond device into a bridge it will only add one of mac adresses into a hash list of mac addresses, say X. This mac address is marked as local. But this bonding interface also has mac address Y. Now then packet arrives with destination address Y, this address is not marked as local and the packed looks like it needs to be forwarded. This packet is then lost which is wrong. Notice that interfaces can be added and removed from bond while it is in bridge. *** When the multiple addresses for bridge port approach failed to solve this issue due to STP I started to think other way to solve this. I returned to previous solution but tweaked one. This patch solves the situation in the bonding without touching bridge code. For every incoming frame to bonding the destination address is compared to current address of the slave device from which tha packet came. If these two match destination address is replaced by mac address of the master. This address is known by bridge so it is delivered properly. Note that the comparsion is not made directly, it's used skb->pkt_type == PACKET_HOST instead. This is "set" previously in eth_type_trans(). I experimentally tried that this works as good as searching through the slave list (v4 of this patch).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We would like to get rid of netdev->trans_start = jiffies; that about all net drivers have to use in their start_xmit() function, and use txq->trans_start instead. This can be done generically in core network, as suggested by David. Some devices, (particularly loopback) dont need trans_start update, because they dont have transmit watchdog. We could add a new device flag, or rely on fact that txq->tran_start can be updated is txq->xmit_lock_owner is different than -1. Use a helper function to hide our choice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch moves some utility functions from mac80211 to cfg80211. Because these functions are doing generic 802.11 operations so they are not mac80211 specific. The moving allows some fullmac drivers to be also benefit from these utility functions.
