After running this bonding setup script modprobe bonding miimon=100 mode=0 max_bonds=1 ifconfig bond0 10.1.1.1/16 ifenslave bond0 eth1 ifenslave bond0 eth3 on s390 with qeth-driven slaves, modprobe -r fails with this message unregister_netdevice: waiting for bond0 to become free. Usage count = 1 due to twice detection of duplicate address. Problem is caused by a missing decrease of ifp->refcnt in addrconf_dad_failure. An extra call of in6_ifa_put(ifp) solves it. Problem has been introduced with commit f2344a13. Signed-off-by: NUrsula Braun <ursula.braun@de.ibm.com> Cc: David S.

dev_can_checksum() incorrectly returns true in these cases: 1. The skb has both out-of-band and in-band VLAN tags and the device supports checksum offload for the encapsulated protocol but only with one layer of encapsulation. 2. The skb has a VLAN tag and the device supports generic checksumming but not in conjunction with VLAN encapsulation. Rearrange the VLAN tag checks to avoid these.

gianfar: Fix crashes on RX path (Was Re: [Bugme-new] [Bug 19692] New: linux-2.6.36-rc5 crash with gianfar ethernet at full line rate traffic) The rx_recycle queue is global per device but can be accesed by many napi handlers at the same time, so it needs full skb_queue primitives (with locking). Otherwise, various crashes caused by broken skbs are possible. This patch resolves, at least partly, bugzilla bug 19692. (Because of some doubts that there could be still something around which is hard to reproduce my proposal is to leave this bug opened for a month.)

There is a bug in the interaction between ipv6_create_tempaddr and addrconf_verify. Because ipv6_create_tempaddr uses the cstamp and tstamp from the public address in creating a private address, if we have not received a router advertisement in a while, tstamp + temp_valid_lft might be < now. If this happens, the new address is created inside ipv6_create_tempaddr, then the loop within addrconf_verify starts again and the address is immediately deleted. We are left with no temporary addresses on the interface, and no more will be created until the public IP address is updated. To avoid this, set the expiry time to be the minimum of the time left on the public address or the config option PLUS the current age of the public interface.

Some panic reports in fib_rules_lookup() show a rule could have a NULL pointer as a next pointer in the rules_list. This can actually happen because of a bug in fib_nl_newrule() : It checks if current rule is the destination of unresolved gotos. (Other rules have gotos to this about to be inserted rule) Problem is it does the resolution of the gotos before the rule is inserted in the rules_list (and has a valid next pointer) Fix this by moving the rules_list insertion before the changes on gotos. A lockless reader can not any more follow a ctarget pointer, unless destination is ready (has a valid next pointer) Reported-by: NOleg A.

One of the previous tproxy related patches split IPv6 defragmentation and connection tracking, but did not correctly add Kconfig stanzas to handle the new dependencies correctly. This patch fixes that by making the config options mirror the setup we have for IPv4: a distinct config option for defragmentation that is automatically selected by both connection tracking and xt_TPROXY/xt_socket. The patch also changes the #ifdefs enclosing IPv6 specific code in xt_socket and xt_TPROXY: we only compile these in case we have ip6tables support enabled.

On a busy network, the macb driver could get stuck in the interrupt handler, quickly triggering the watchdog, due to a confluence of factors: 1. macb_poll re-enables interrupts unconditionally, even when it will be called again because it exhausted its rx budget 2. macb_interrupt only disables interrupts after scheduling macb_poll, but scheduling fails when macb_poll is already scheduled because it didn't call napi_complete 3. macb_interrupt loops until the interrupt status register is clear, which will never happen in this case if the driver doesn't disable the RX interrupt Since macb_interrupt runs in interrupt context, this effectively locks up the machine, triggering the hardware watchdog. This issue was readily reproducible on a flooded network with a modified 2.6.27.48 kernel. The same problem appears to still be in the 2.6.36-rc8 driver code, so I am submitting this patch against that version. I have not tested this version of the patch except to make sure the kernel compiles. Signed-off-by: NJoshua Hoke <joshua.hoke@sixnet.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The ath9k aggregation code was already checking the rate control probe flag to prevent starting an aggregate frame with a sampling rate.
