* x86: fix section mismatch warnings when referencing notifiersSam Ravnborg2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix the following warnings: WARNING: arch/x86/kernel/built-in.o(.exit.text+0xf8): Section mismatch in reference from the function msr_exit() to the variable .cpuinit.data:msr_class_cpu_notifier WARNING: arch/x86/kernel/built-in.o(.exit.text+0x158): Section mismatch in reference from the function cpuid_exit() to the variable .cpuinit.data:cpuid_class_cpu_notifier WARNING: arch/x86/kernel/built-in.o(.exit.text+0x171): Section mismatch in reference from the function microcode_exit() to the variable .cpuinit.data:mc_cpu_notifier In all three cases there were a function annotated __exit that referenced a variable annotated __cpuinitdata. The fix was to replace the annotation of the notifier with __refdata to tell modpost that the reference to a _cpuinit function in the notifier are OK. The unregister call that references the notifier variable will simple delete the function pointer so there is no problem ignoring the reference. Note: This looks like another case where __cpuinit has been used as replacement for proper use of CONFIG_HOTPLUG_CPU to decide what code are used for HOTPLUG_CPU.

* x86: silence section mismatch warning in smpboot_64.cSam Ravnborg2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Silence the following warning: WARNING: o-x86_64/arch/x86/kernel/built-in.o(.text+0x17cd3): Section mismatch in reference from the function remove_cpu_from_maps() to the variable .cpuinit.data:cpu_initialized remove_cpu:maps() had a single user: __cpu_disable() so mark it static and annotate it with __ref to silence the warning from modpost. _cpu_disable() has a single user in kernel/cpu.c: => take_cpu_down() which again has a single user in the following call: => __stop_machine_run(take_cpu_down, &tcd_param, cpu); Here a kthread is created. So maybe the warning is correct and the right fix is to remove the __cpuinitdata annotation of cpu_initialized? Note: The analysis were disturbed by the fact that we had a variable with the same name in cpu/common.c - but this is 32 bit only] Note: Should smpboot_64 use cpu_clear()?

| * block: kill swap_io_context()Jens Axboe2008-02-01
| | | | | | | | | | | | | | | | | | | | It blindly copies everything in the io_context, including the lock. That doesn't work so well for either lock ordering or lockdep.

| * as-iosched: fix inconsistent ioc->lock contextJens Axboe2008-02-01
| | | | | | | | | | | | | | | | | | | | | | Since it's acquired from irq context, all locking must be of the irq safe variant. Most are already inside the queue lock (which already disables interrupts), but the io scheduler rmmod path always has irqs enabled and the put_io_context() path may legally be called with irqs enabled (even if it isn't usually). So fixup those two. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| | | | | | | | | | | | | | | | | | | | Andre Majorel <aym-xunil@teaser.fr> points out that if we only updated the atime when we transfer some data, we deviate from the standard of always updating the atime.

Some examples: - Classic SFQ hash: tc filter add ... flow hash \ keys src,dst,proto,proto-src,proto-dst divisor 1024 - Classic SFQ hash, but using information from conntrack to work properly in combination with NAT: tc filter add ... flow hash \ keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024 - Map destination IPs of 192.168.0.0/24 to classids 1-257: tc filter add ... flow map \ key dst addend -192.168.0.0 divisor 256 - alternatively: tc filter add ... flow map \ key dst and 0xff - similar, but reverse ordered: tc filter add ... flow map \ key dst and 0xff xor 0xff Perturbation is currently not supported because we can't reliable kill the timer on destruction.

| * | [IPV4] route cache: Introduce rt_genid for smooth cache invalidationEric Dumazet2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current ip route cache implementation is not suited to large caches. We can consume a lot of CPU when cache must be invalidated, since we currently need to evict all cache entries, and this eviction is sometimes asynchronous. min_delay & max_delay can somewhat control this asynchronism behavior, but whole thing is a kludge, regularly triggering infamous soft lockup messages. When entries are still in use, this also consumes a lot of ram, filling dst_garbage.list. A better scheme is to use a generation identifier on each entry, so that cache invalidation can be performed by changing the table identifier, without having to scan all entries. No more delayed flushing, no more stalling when secret_interval expires. Invalidated entries will then be freed at GC time (controled by ip_rt_gc_timeout or stress), or when an invalidated entry is found in a chain when an insert is done. Thus we keep a normal equilibrium. This patch : - renames rt_hash_rnd to rt_genid (and makes it an atomic_t) - Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit) - Checks entry->rt_genid at appropriate places :

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the old policer code is gone, TC actions are needed for policing. The ingress qdisc can get packets directly from netif_receive_skb() in case TC actions are enabled or through netfilter otherwise, but since without TC actions there is no policer the only thing it actually does is count packets. Remove the netfilter support and always require TC actions. Signed-off-by: Patrick McHardy <kaber@trash.net> Acked-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S.

| * | [VLAN]: set_rx_mode support for unicast address listChris Leech2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuse the existing logic for multicast list synchronization for the unicast address list. The core of dev_mc_sync/unsync are split out as __dev_addr_sync/unsync and moved from dev_mcast.c to dev.c. These are then used to implement dev_unicast_sync/unsync as well. I'm working on cleaning up Intel's FCoE stack, which generates new MAC addresses from the fibre channel device id assigned by the fabric as per the current draft specification in T11. When using such a protocol in a VLAN environment it would be nice to not always be forced into promiscuous mode, assuming the underlying Ethernet driver supports multiple unicast addresses as well.
