* [NET]: Prevent transmission after dev_deactivateHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dev_deactivate function has bit-rotted since the introduction of lockless drivers. In particular, the spin_unlock_wait call at the end has no effect on the xmit routine of lockless drivers. With a little bit of work, we can make it much more useful by providing the guarantee that when it returns, no more calls to the xmit routine of the underlying driver will be made. The idea is simple. There are two entry points in to the xmit routine. The first comes from dev_queue_xmit. That one is easily stopped by using synchronize_rcu. This works because we set the qdisc to noop_qdisc before the synchronize_rcu call. That in turn causes all subsequent packets sent to dev_queue_xmit to be dropped. The synchronize_rcu call also ensures all outstanding calls leave their critical section. The other entry point is from qdisc_run. Since we now have a bit that indicates whether it's running, all we have to do is to wait until the bit is off. I've removed the loop to wait for __LINK_STATE_SCHED to clear. This is useless because netif_wake_queue can cause it to be set again. It is also harmless because we've disarmed qdisc_run. I've also removed the spin_unlock_wait on xmit_lock because its only purpose of making sure that all outstanding xmit_lock holders have exited is also given by dev_watchdog_down.

* [IPV6]: Fix source address selection.Łukasz Stelmach2006-06-23
| | | | | | | | | | | | | Two additional labels (RFC 3484, sec. 10.3) for IPv6 addreses are defined to make a distinction between global unicast addresses and Unique Local Addresses (fc00::/7, RFC 4193) and Teredo (2001::/32, RFC 4380). It is necessary to avoid attempts of connection that would either fail (eg. fec0:: to 2001:feed::) or be sub-optimal (2001:0:: to 2001:feed::).

* [NET]: Avoid allocating skb in skb_padHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | Yeah, it's a hack, but it is only temporary until Alan's patches reworking this area make it in. We really should not care what devices below us are doing, especially when we do not really know what type of devices they are. This patch relies on the fact that the endpoint devices do not have a driver assigned to us. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MMC specification allows non-power of two block sizes. As such, we should not pass the log2 block size to host drivers, but instead pass the byte size. However, ARM MMCI can only work with log2 block size, so continue to pass both the log2 block size and byte block size. This means that for the moment, the byte block size must remain a power of two, but this is the first stage of removing this restriction for other hosts.

We do not convert all instructions to the VFP-equivalent (yet) since binutils appears to barf on "fmrx rn, fpinst" and doesn't provide any other way (other than using the mrc equivalent) to encode this instruction - which is rather a problem when you have a VFP implementation which requires these instructions.

Unfortunately, the kernel hard-codes VFP instructions into the thread switch, which prevents this being run-time selectable. Solve this by introducing a notifier which things such as VFP can hook into to be informed of events which affect the VFP subsystem (eg, creation and destruction of threads, switches between threads.)

Due to non-existent ordering between cpu_hotplug lock and dbs_mutex. Basically a race condition between cpu_down() and do_dbs_timer(). cpu_down() flow: * cpu_down() call for CPU 1 * Takes hot plug lock * Calls pre down notifier * cpufreq notifier handler calls cpufreq_driver_target() which takes cpu_hotplug lock again. OK as cpu_hotplug lock is recursive in same process context * CPU 1 goes down * Calls post down notifier * cpufreq notifier handler calls ondemand event stop which takes dbs_mutex So, cpu_hotplug lock is taken before dbs_mutex in this flow. do_dbs_timer is triggerred by a periodic timer event. It first takes dbs_mutex and then takes cpu_hotplug lock in cpufreq_driver_target(). Note the reverse order here compared to above. So, if this timer event happens at right moment during cpu_down, system will deadlok. Attached patch fixes the issue for both ondemand and conservative.

I get a steady stream of mail which I don't really do anything useful with; the cpufreq list seems like a better destination, unless someone wants to get the mail directly. Also clean up a couple of ancient comments which don't really apply anymore (as far as I know, nobody has ever damaged a CPU with this driver).

This got left in when the padding bad write patch was added and is actually not needed.
