* [NETNS]: Add namespace parameter to ip_route_output_slow.Denis V. Lunev2008-01-281-10/+11

* [NETNS]: Add namespace parameter to ip_dev_find.Denis V. Lunev2008-01-285-8/+8

* [NETNS]: Add netns parameter to fib_select_default.Denis V. Lunev2008-01-282-3/+4
| | | | | | | | | Currently fib_select_default calls fib_get_table() with the init_net. Prepare it to provide a correct namespace to lookup default route. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4]: Consolidate fib_select_default.Denis V. Lunev2008-01-282-10/+14
| | | | | | | | | The difference in the implementation of the fib_select_default when CONFIG_IP_MULTIPLE_TABLES is (not) defined looks negligible. Consolidate it and place into fib_frontend.c. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4] fib_trie: avoid rescan on dumpStephen Hemminger2008-01-281-13/+21
| | | | | | | | | | | | | | | This converts dumping (and flushing) of large route tables form O(N^2) to O(N). If the route dump took multiple pages then the dump routine gets called again. The old code kept track of location by counter, the new code instead uses the last key. This is a really big win ( 0.3 sec vs 12 sec) for big route tables. One side effect is that if the table changes during the dump, then the last key will not be found, and we will return -EBUSY.

* [IPV4] fib_trie: dump table in sorted orderStephen Hemminger2008-01-281-35/+39
| | | | | | | | | It is easier with TRIE to dump the data traversal rather than interating over every possible prefix. This saves some time and makes the dump come out in sorted order. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* rc80211-pid: fix last_sample initializationStefano Brivio2008-01-281-0/+2
| | | | | | | | | | | | Fix last_sample initialization. kzalloc'ing the per-STA data wasn't enough, as jiffies can assume negative values as well. This fixes a bug which prevented correct PID operation for a while after booting. Thanks to Michael Buesch for reporting this.

* mac80211: fix RCU locking in __ieee80211_rx_handle_packetJohannes Berg2008-01-281-1/+0
| | | | | | | | | | | Commit c7a51bda ("mac80211: restructure __ieee80211_rx") extracted __ieee80211_rx_handle_packet out of __ieee80211_rx and hence changed the locking rules for __ieee80211_rx_handle_packet(), it is now invoked under RCU lock. There is, however, one instance left where it contains an rcu_read_unlock() in an error path, which is a bug. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: Assign correct TID for local bridged packetsGuy Cohen2008-01-281-4/+5
| | | | | | | | | | | | This patch assigns correct TID to frames transmitted between two stations in the same BSS in AP mode. The problem is that skb->protocol is not set to ETH_P_IP and it is wrong to use that field at this stage. The fix compares the LLC/Protocol headers explicitly to check if the encapsulated frame is IP frame Signed-off-by: Guy Cohen <guy.cohen@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [DST]: shrinks sizeof(struct rtable) by 64 bytes on x86_64Eric Dumazet2008-01-281-6/+7
| | | | | | | | | | | | | | | | | | | On x86_64, sizeof(struct rtable) is 0x148, which is rounded up to 0x180 bytes by SLAB allocator. We can reduce this to exactly 0x140 bytes, without alignment overhead, and store 12 struct rtable per PAGE instead of 10. rate_tokens is currently defined as an "unsigned long", while its content should not exceed 6*HZ. It can safely be converted to an unsigned int. Moving tclassid right after rate_tokens to fill the 4 bytes hole permits to save 8 bytes on 'struct dst_entry', which finally permits to save 8 bytes on 'struct rtable' Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* [NETNS][FRAGS]: Make the pernet subsystem for fragments.Pavel Emelyanov2008-01-283-2/+32
| | | | | | | | | | On namespace start we mainly prepare the ctl variables. When the namespace is stopped we have to kill all the fragments that point to this namespace. The inet_frags_exit_net() handles it. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Make the LRU list per namespace.Pavel Emelyanov2008-01-284-7/+7
| | | | | | | | | | | | | The inet_frags.lru_list is used for evicting only, so we have to make it per-namespace, to evict only those fragments, who's namespace exceeded its high threshold, but not the whole hash. Besides, this helps to avoid long loops in evictor. The spinlock is not per-namespace because it protects the hash table as well, which is global.

* [NETNS][FRAGS]: Isolate the secret interval from namespaces.Pavel Emelyanov2008-01-284-17/+7
| | | | | | | | | | | | Since we have one hashtable to lookup the fragment, having different secret_interval-s for hash rebuild doesn't make sense, so move this one to inet_frags. The inet_frags_ctl becomes empty after this, so remove it. The appropriate ctl table is kept read-only in namespaces. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Make thresholds work in namespaces.Pavel Emelyanov2008-01-284-28/+27
| | | | | | | | | | | This is the same as with the timeout variable. Currently, after exceeding the high threshold _all_ the fragments are evicted, but it will be fixed in later patch. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Make the net.ipv4.ipfrag_timeout work in namespaces.Pavel Emelyanov2008-01-284-16/+16
| | | | | | | | | | | Move it to the netns_frags, adjust the usage and make the appropriate ctl table writable. Now fragment, that live in different namespaces can live for different times. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Duplicate sysctl tables for new namespaces.Pavel Emelyanov2008-01-282-6/+77
| | | | | | | | | | | | Each namespace has to have own tables to tune their different parameters, so duplicate the tables and register them. All the tables in sub-namespaces are temporarily made read-only. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Make the mem counter per-namespace.Pavel Emelyanov2008-01-286-46/+50
| | | | | | | | This is also simple, but introduces more changes, since then mem counter is altered in more places. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Make the nqueues counter per-namespace.Pavel Emelyanov2008-01-286-9/+19
| | | | | | | | This is simple - just move the variable from struct inet_frags to struct netns_frags and adjust the usage appropriately. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Make the inet_frag_queue lookup work in namespaces.Pavel Emelyanov2008-01-284-19/+27
| | | | | | | | | | | | | | | | Since fragment management code is consolidated, we cannot have the pointer from inet_frag_queue to struct net, since we must know what king of fragment this is. So, I introduce the netns_frags structure. This one is currently empty, but will be eventually filled with per-namespace attributes. Each inet_frag_queue is tagged with this one. The conntrack_reasm is not "netns-izated", so it has one static netns_frags instance to keep working in init namespace. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS][FRAGS]: Move ctl tables around.Pavel Emelyanov2008-01-287-121/+166
| | | | | | | | | | | | | | | | This is a preparation for sysctl netns-ization. Move the ctl tables to the files, where the tuning variables reside. Plus make the helpers to register the tables. This will simplify the later patches and will keep similar things closer to each other. ipv4, ipv6 and conntrack_reasm are patched differently, but the result is all the tables are in appropriate files.
