2011-03-21IPVS: Use global mutex in ip_vs_app.cSimon Horman
As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.

2011-03-21ACPI, APEI, Add PCIe AER error information printing supportHuang Ying
The AER error information printing support is implemented in drivers/pci/pcie/aer/aer_print.c. So some string constants, functions and macros definitions can be re-used without being exported. The original PCIe AER error information printing function is not re-used directly because the overall format is quite different. And changing the original printing format may make some original users' scripts broken.

2011-03-21PCIe, AER, use pre-generated prefix in error information printingHuang Ying
When printing PCIe AER error information, each line is prefixed with PCIe device and driver information. In original implementation, the prefix is generated when each line is printed. In fact, all lines share the same prefix. So this patch pre-generated the prefix, and use that one when each line is printed. In addition to common prefix can be pre-generated, the trailing white spaces in string constants and NULLs in char * array constants can be removed too. These can reduce the object file size further. The size of object file before and after changing is as follow: text data bss dec before: 3038 0 0 3038 after: 2118 0 0 2118 Signed-off-by: Huang Ying <ying.huang@intel.com> CC: Jesse Barnes <jbarnes@virtuousgeek.org> CC: Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2011-03-21ACPI, APEI, Add ERST record ID cacheHuang Ying
APEI ERST firmware interface and implementation has no multiple users in mind. For example, if there is four records in storage with ID: 1, 2, 3 and 4, if two ERST readers enumerate the records via GET_NEXT_RECORD_ID as follow, reader 1 reader 2 1 2 3 4 -1 -1 where -1 signals there is no more record ID. Reader 1 has no chance to check record 2 and 4, while reader 2 has no chance to check record 1 and 3. And any other GET_NEXT_RECORD_ID will return -1, that is, other readers will has no chance to check any record even they are not cleared by anyone. This makes raw GET_NEXT_RECORD_ID not suitable for used by multiple users. To solve the issue, an in-memory ERST record ID cache is designed and implemented. When enumerating record ID, the ID returned by GET_NEXT_RECORD_ID is added into cache in addition to be returned to caller. So other readers can check the cache to get all record ID available.

2011-03-21ext4: add more tracepoints and use dev_t in the trace bufferJiaying Zhang
- Add more ext4 tracepoints. - Change ext4 tracepoints to use dev_t field with MAJOR/MINOR macros so that we can save 4 bytes in the ring buffer on some platforms. - Add sync_mode to ext4_da_writepages, ext4_da_write_pages, and ext4_da_writepages_result tracepoints.

2011-03-21veth: Fix the byte countersEric W. Biederman
Commit 44540960 "veth: move loopback logic to common location" introduced a bug in the packet counters. I don't understand why that happened as it is not explained in the comments and the mut check in dev_forward_skb retains the assumption that skb->len is the total length of the packet. I just measured this emperically by setting up a veth pair between two noop network namespaces setting and attempting a telnet connection between the two. I saw three packets in each direction and the byte counters were exactly 14*3 = 42 bytes high in each direction. I got the actual packet lengths with tcpdump. So remove the extra ETH_HLEN from the veth byte count totals. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-21net ipv6: Fix duplicate /proc/sys/net/ipv6/neigh directory entries.Eric W. Biederman
When I was fixing issues with unregisgtering tables under /proc/sys/net/ipv6/neigh by adding a mount point it appears I missed a critical ordering issue, in the ipv6 initialization. I had not realized that ipv6_sysctl_register is called at the very end of the ipv6 initialization and in particular after we call neigh_sysctl_register from ndisc_init. "neigh" needs to be initialized in ipv6_static_sysctl_register which is the first ipv6 table to initialized, and definitely before ndisc_init. This removes the weirdness of duplicate tables while still providing a "neigh" mount point which prevents races in sysctl unregistering.

2011-03-21macvlan: Fix use after free of struct macvlan_port.Eric W. Biederman
When the macvlan driver was extended to call unregisgter_netdevice_queue in 23289a37e2b127dfc4de1313fba15bb4c9f0cd5b, a use after free of struct macvlan_port was introduced. The code in dellink relied on unregister_netdevice actually unregistering the net device so it would be safe to free macvlan_port. Since unregister_netdevice_queue can just queue up the unregister instead of performing the unregiser immediately we free the macvlan_port too soon and then the code in macvlan_stop removes the macaddress for the set of macaddress to listen for and uses memory that has already been freed. To fix this add a reference count to track when it is safe to free the macvlan_port and move the call of macvlan_port_destroy into macvlan_uninit which is guaranteed to be called after the final macvlan_port_close.

2011-03-21can: c_can: Do basic c_can configuration _before_ enabling the interruptsJan Altenberg
I ran into some trouble while testing the SocketCAN driver for the BOSCH C_CAN controller. The interface is not correctly initialized, if I put some CAN traffic on the line, _while_ the interface is being started (which means: the interface doesn't come up correcty, if there's some RX traffic while doing 'ifconfig can0 up'). The current implementation enables the controller interrupts _before_ doing the basic c_can configuration. I think, this should be done the other way round. The patch below fixes things for me.
