| * atm: sk_wmem_alloc initial value is oneEric Dumazet2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | commit 2b85a34e911bf483c27cfdd124aeb1605145dc80 (net: No more expensive sock_hold()/sock_put() on each tx) changed initial sk_wmem_alloc value.

| * net: group address list and its countJiri Pirko2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions). I wanted to introduce this patch before I'll post a multicast lists conversion.

| * ipv4: Fix fib_trie rebalancing, part 2Jarek Poplawski2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My previous patch, which explicitly delays freeing of tnodes by adding them to the list to flush them after the update is finished, isn't strict enough. It treats exceptionally tnodes without parent, assuming they are newly created, so "invisible" for the read side yet. But the top tnode doesn't have parent as well, so we have to exclude all exceptions (at least until a better way is found). Additionally we need to move rcu assignment of this node before flushing, so the return type of the trie_rebalance() function is changed.

| * net: sk_wmem_alloc has initial value of one, not zeroEric Dumazet2009-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2b85a34e911bf483c27cfdd124aeb1605145dc80 (net: No more expensive sock_hold()/sock_put() on each tx) changed initial sk_wmem_alloc value. Some protocols check sk_wmem_alloc value to determine if a timer must delay socket deallocation. We must take care of the sk_wmem_alloc value being one instead of zero when no write allocations are pending. Reported by Ingo Molnar, and full diagnostic from David Miller. This patch introduces three helpers to get read/write allocations and a followup patch will use these helpers to report correct write allocations to user.

| * mac80211: fix wext bssid/ssid settingJohannes Berg2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When changing to a new BSSID or SSID, the code in ieee80211_set_disassoc() needs to have the old data still valid to be able to disconnect and clean up properly. Currently, however, the old data is thrown away before ieee80211_set_disassoc() is ever called, so fix that by calling the function _before_ the old data is overwritten. This is (one of) the issue(s) causing mac80211 to hold cfg80211's BSS structs forever, and them thus being returned in scan results after they're long gone. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2015 Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * mac80211: disconnect when user changes channelJohannes Berg2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we do not disconnect when a channel switch is requested, we end up eventually detection beacon loss from the AP and then disconnecting, without ever really telling the AP, so we might just as well disconnect right away. Additionally, this fixes a problem with iwlwifi where the driver will clear some internal state on channel changes like this and then get confused when we actually go clear that state from mac80211. It may look like this patch drops the no-IBSS check, but that is already handled by cfg80211 in the wext handler it provides for IBSS (cfg80211_ibss_wext_siwfreq).

| * mac80211: add queue debugfs fileJohannes Berg2009-06-15
| | | | | | | | | | | | | | | | | | | | | | I suspect that some driver bugs can cause queues to be stopped while they shouldn't be, but it's hard to find out whether that is the case or not without having any visible information about the queues.

| * mac80211: Do not try to associate with an empty SSIDJouni Malinen2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It looks like some programs (e.g., NM) are setting an empty SSID with SIOCSIWESSID in some cases. This seems to trigger mac80211 to try to associate with an invalid configuration (wildcard SSID) which will result in failing associations (or odd issues, potentially including kernel panic with some drivers) if the AP were to actually accept this anyway). Only start association process if the SSID is actually set. This speeds up connection with NM in number of cases and avoids sending out broken association request frames.

| * | page allocator: use a pre-calculated value instead of num_online_nodes() in ↵Christoph Lameter2009-06-16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fast paths num_online_nodes() is called in a number of places but most often by the page allocator when deciding whether the zonelist needs to be filtered based on cpusets or the zonelist cache. This is actually a heavy function and touches a number of cache lines. This patch stores the number of online nodes at boot time and updates the value when nodes get onlined and offlined. The value is then used in a number of important paths in place of num_online_nodes().

The current method to add a new tracepoint into an existing system is to write the trace point macro in the trace header with one of the macros TRACE_EVENT, TRACE_FORMAT or DECLARE_TRACE, then they must add the same named item into the C file with the macro DEFINE_TRACE(name) and then add the trace point. This change cuts out the needing to add the DEFINE_TRACE(name). Every file that uses the tracepoint must still include the trace/<type>.h file, but the one C file must also add a define before the including of that file. #define CREATE_TRACE_POINTS #include <trace/mytrace.h> This will cause the trace/mytrace.h file to also produce the C code necessary to implement the trace point. Note, if more than one trace/<type>.h is used to create the C code it is best to list them all together. #define CREATE_TRACE_POINTS #include <trace/foo.h> #include <trace/bar.h> #include <trace/fido.h> Thanks to Mathieu Desnoyers and Christoph Hellwig for coming up with the cleaner solution of the define above the includes over my first design to have the C code include a "special" header. This patch converts sched, irq and lockdep and skb to use this new method.

On IBM pserver systems this causes a resource leak that results in running out of bus address space (10 cthon iterations will reproduce it). The code was mapping the full page but only unmapping the actual header length. The fix is to only map the header length. I also cleaned up the use of ib_dma_map_page() calls since the unmap logic always uses ib_dma_unmap_single(). I made these symmetrical.

It depends on RCU delaying the real destruction, but if RCU readers start after call_rcu() and before parent update they could access freed memory. It is currently prevented with preempt_disable() on the update side, but it's not safe, except maybe classic RCU, plus it conflicts with memory allocations with GFP_KERNEL flag used from these functions. This patch explicitly delays freeing of tnodes by adding them to the list, which is flushed after the update is finished.
