* ipv6: cancel to setting local_df in ip6_xmit()Shan Wei2010-04-16
| | | | | | | | | | | | commit f88037(sctp: Drop ipfargok in sctp_xmit function) has droped ipfragok and set local_df value properly. So the change of commit 77e2f1(ipv6: Fix ip6_xmit to send fragments if ipfragok is true) is not needed. So the patch remove them.

| | * mac80211: check whether scan is in progress before queueing scan_workTeemu Paasikivi2010-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As scan_work is queued from work_work it needs to be checked if scan has been started during execution of work_work. Otherwise, when hw scan is used, the stack gets error about hw being busy with ongoing scan. This causes the stack to abort scan without notifying the driver about it. This leads to a situation where the hw is scanning and the stack thinks it's not. Then when the scan finishes, the stack will complain by warnings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We delay the skb linearising in ieee80211_rx_h_decrypt so that frames do not require software decryption are not linearized.

Fix these issues by using the regular aggregation session teardown code and blocking new aggregation sessions, all before the station is really destructed. As a side effect, this gets rid of the long code block to destroy aggregation safely. Additionally, rename tid_state_rx which can only have the values IDLE and OPERATIONAL to tid_active_rx to make it easier to understand that there is no bitwise stuff going on on the RX side -- the TX side remains because it needs to keep track of the driver and peer states.

In order to meet these requirements, user space applications may need to clear authentication or association state in some cases. Currently, this can be done with deauth/disassoc command, but that ends up sending out Deauthentication or Disassociation frame unnecessarily. Add a new nl80211 attribute to allow this sending of the frame be skipped, but with all other deauth/disassoc operations being completed. Similar state change is also needed for IEEE 802.11r FT protocol in the FT-over-DS case which does not use Authentication frame exchange in a transition to another BSS. For this to work with cfg80211, an authentication entry needs to be created for the target BSS without sending out an Authentication frame. The nl80211 authentication command can be used for this purpose, too, with the new attribute to indicate that the command is only for changing local state. This enables wpa_supplicant to complete FT-over-DS transition successfully. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When selecting the RX key for group-addressed robust management frames, we do not actually select any BIP key if the frame is unprotected (since we cannot find the key index from MMIE). This results in the drop_unencrypted check in failing to drop the frame. It is enough to verify that we have a STA entry for the transmitter and that MFP is enabled for that STA; we do not need to check rx->key here. This fixes BIP processing for unprotected, group-addressed, robust management frames. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

We ended up picking it as a default mechanism for every management whenever we did not have a STA entry for the destination (e.g., for Probe Response to a STA that is not associated). While the extra MMIE in the end of management frames should not break frames completed in most cases, there is no point in doing this. Fix key selection to pick the default management key only if the frame is sent to multicast/broadcast address and the frame is a robust management frame.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When management frame protection (IEEE 802.11w) is used, the deauthentication and disassociation frames must be protected whenever the encryption keys are configured. We were removing the STA entry and with it, the keys, just before actually sending out these frames which meant that the frames went out unprotected. The AP will drop them in such a case. Fix this by reordering the operations a bit so that sta_info_destroy_addr() gets called only after ieee80211_send_deauth_disassoc(). Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.

Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT_TABLE. The table number is stored in the raw socket data and affects all following ipmr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT_TABLE_DEFAULT) is created with a default routing rule pointing to it. Newly created pimreg devices have the table number appended ("pimregX"), with the exception of devices created in the default table, which are named just "pimreg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, IPPROTO_IP, MRT_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip mrule add iif eth0 lookup 123 # ip mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both functions are equivalent, consolidate them since a following patch needs a third implementation for multicast routing. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function dst_ifdown is called only two places but in a non- performance critical code path, there is no reason to inline it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | skb_bond_should_drop() is too big to be inlined. This patch reduces kernel text size, and its compilation time as well (shrinking include/linux/netdevice.h) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* | | | IPv6: only notify protocols if address is compeletely gonestephen hemminger2010-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The notifier for address down should only be called if address is completely gone, not just being marked as tentative on link transistion. The code in net-next would case bonding/sctp/s390 to see address disappear on link down, but they would never see it reappear on link up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since an address in hash list has to already have a ref count, no additional ref count is needed. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | | | IPv6: keep tentative addresses in hash tablestephen hemminger2010-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When link goes down, want address to be preserved but in a tentative state, therefore it has to stay in hash list. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | | | IPv6: keep route for tentative addressstephen hemminger2010-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes preserve IPv6 address when link goes down (good). But would cause address to point to dead dst entry (bad). The simplest fix is to just not delete route if address is being held for later use.
