2011-05-20sanitize <linux/prefetch.h> usageLinus Torvalds
Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, which uncovered several cases that had apparently relied on that rather obscure header file dependency. So this fixes things up a bit, using grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]') grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]') to guide us in finding files that either need <linux/prefetch.h> inclusion, or have it despite not needing it. There are more of them around (mostly network drivers), but this gets many core ones.

2011-05-20macvlan: remove one synchronize_rcu() callEric Dumazet
When one macvlan device is dismantled, we can avoid one synchronize_rcu() call done after deletion from hash list, since caller will perform a synchronize_net() call after its ndo_stop() call. Add a new netdev->dismantle field to signal this dismantle intent. Reduces RTNL hold time.

2011-05-19SCTP: fix race between sctp_bind_addr_free() and sctp_bind_addr_conflict()Jacek Luczak
During the sctp_close() call, we do not use rcu primitives to destroy the address list attached to the endpoint. At the same time, we do the removal of addresses from this list before attempting to remove the socket from the port hash As a result, it is possible for another process to find the socket in the port hash that is in the process of being closed. It then proceeds to traverse the address list to find the conflict, only to have that address list suddenly disappear without rcu() critical section. Fix issue by closing address list removal inside RCU critical section. Race can result in a kernel crash with general protection fault or kernel NULL pointer dereference: kernel: general protection fault: 0000 [#1] SMP kernel: RIP: 0010:[<ffffffffa02f3dde>] [<ffffffffa02f3dde>] sctp_bind_addr_conflict+0x64/0x82 [sctp] kernel: Call Trace: kernel: [<ffffffffa02f415f>] ? sctp_get_port_local+0x17b/0x2a3 [sctp] kernel: [<ffffffffa02f3d45>] ? sctp_bind_addr_match+0x33/0x68 [sctp] kernel: [<ffffffffa02f4416>] ? sctp_do_bind+0xd3/0x141 [sctp] kernel: [<ffffffffa02f5030>] ? sctp_bindx_add+0x4d/0x8e [sctp] kernel: [<ffffffffa02f5183>] ? sctp_setsockopt_bindx+0x112/0x4a4 [sctp] kernel: [<ffffffff81089e82>] ? generic_file_aio_write+0x7f/0x9b kernel: [<ffffffffa02f763e>] ? sctp_setsockopt+0x14f/0xfee [sctp] kernel: [<ffffffff810c11fb>] ? do_sync_write+0xab/0xeb kernel: [<ffffffff810e82ab>] ? fsnotify+0x239/0x282 kernel: [<ffffffff810c2462>] ? alloc_file+0x18/0xb1 kernel: [<ffffffff8134a0b1>] ? compat_sys_setsockopt+0x1a5/0x1d9 kernel: [<ffffffff8134aaf1>] ? compat_sys_socketcall+0x143/0x1a4 kernel: [<ffffffff810467dc>] ? sysenter_dispatch+0x7/0x32 Signed-off-by: Jacek Luczak <luczak.jacek@gmail.com> Acked-by: Vlad Yasevich <vladislav.yasevich@hp.com> CC: Eric Dumazet <eric.dumazet@gmail.com> Reviewed-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-05-19ipv6: reduce per device ICMP mib sizesEric Dumazet
ipv6 has per device ICMP SNMP counters, taking too much space because they use percpu storage. needed size per device is : (512+4)*sizeof(long)*number_of_possible_cpus*2 On a 32bit kernel, 16 possible cpus, this wastes more than 64kbytes of memory per ipv6 enabled network device, taken in vmalloc pool. Since ICMP messages are rare, just use shared counters (atomic_long_t) Per network space ICMP counters are still using percpu memory, we might also convert them to shared counters in a future patch.

2011-05-16mac80211: sparse RCU annotationsJohannes Berg
This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-05-16mac80211: fix TX a-MPDU lockingJohannes Berg
During my quest to make mac80211 not have any RCU warnings from sparse, I came across the a-MPDU code again and it wasn't quite clear why it isn't racy. So instead of assigning the tid_tx array with just the spinlock held in ieee80211_start_tx_ba_session use a separate temporary array protected only by the spinlock and protect all assignments to the "live" array by both the spinlock and the mutex so that other code is easily verified to be correct. Due to pointer assignment atomicity I don't think this is a real issue, but I'm not sure, especially on Alpha the current code might be problematic.

2011-05-16cfg80211: advertise possible interface combinationsJohannes Berg
Add the ability to advertise interface combinations in nl80211. This allows the driver to indicate what the combinations are that it supports. "Combinations" of just a single interface are implicit, as previously. Note that cfg80211 will enforce that the restrictions are met, but not for all drivers yet (once all drivers are updated, we can remove the flag and enforce for all). When no combinations are actually supported, an empty list will be exported so that userspace can know if the kernel exported this info or not (although it isn't clear to me what tools using the info should do if the kernel didn't export it). Since some interface types are purely virtual/software and don't fit the restrictions, those are exposed in a new list of pure SW types, not subject to restrictions. This mainly exists to handle AP-VLAN and monitor interfaces in mac80211. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
