Pull timer updates from Ingo Molnar: "The main purpose is to fix a full dynticks bug related to virtualization, where steal time accounting appears to be zero in /proc/stat even after a few seconds of competing guests running busy loops in a same host CPU. It's not a regression though as it was there since the beginning.

arch: Remove stub cputime.h headers

2014-03-13T15:09:30Z

Many architectures have a stub cputime.h that only include the default cputime.h Lets remove the useless headers, we only need to mention that we want the default headers on the Kbuild files.

locking/mcs: Order the header files in Kbuild of each architecture in alphabetical order

2014-02-09T20:17:50Z

We perform a clean up of the Kbuid files in each architecture. We order the files in each Kbuild in alphabetical order by running the below script. for i in arch/*/include/asm/Kbuild do cat $i | gawk '/^generic-y/ { i = 3; do { for (; i <= NF; i++) { if ($i == "\\") { getline; i = 1; continue; } if ($i != "") hdr[$i] = $i; } break; } while (1); next; } // { print $0; } END { n = asort(hdr); for (i = 1; i <= n; i++) print "generic-y += " hdr[i]; }' > ${i}.sorted; mv ${i}.sorted $i; done Signed-off-by: Tim Chen Cc: Arnd Bergmann Cc: Matthew R Wilcox Cc: AswinChandramouleeswaran Cc: Dave Hansen Cc: "Paul E.McKenney" Cc: Scott J Norton Cc: Will Deacon Cc: "Figo.zhang" Cc: Linus Torvalds Cc: Rik van Riel Cc: Waiman Long Cc: Peter Hurley Cc: Andrea Arcangeli Cc: Tim Chen Cc: Alex Shi Cc: Raghavendra K T Cc: Andi Kleen Cc: George Spelvin Cc: MichelLespinasse Cc: Ingo Molnar Cc: "H.

From Ben Hutchings. 5) Add better trace events for debugging driver datapath problems, also from Ben Hutchings. 6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we have a small send and a previous packet is already in the qdisc or device queue, defer until TX completion or we get more data. 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko. 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel Borkmann. 9) Share IP header compression code between Bluetooth and IEEE802154 layers, from Jukka Rissanen. 10) Fix ipv6 router reachability probing, from Jiri Benc. 11) Allow packets to be captured on macvtap devices, from Vlad Yasevich. 12) Support tunneling in GRO layer, from Jerry Chu. 13) Allow bonding to be configured fully using netlink, from Scott Feldman. 14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can already get the TCI. From Atzm Watanabe. 15) New "Heavy Hitter" qdisc, from Terry Lam. 16) Significantly improve the IPSEC support in pktgen, from Fan Du. 17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom Herbert. 18) Add Proportional Integral Enhanced packet scheduler, from Vijay Subramanian. 19) Allow openvswitch to mmap'd netlink, from Thomas Graf. 20) Key TCP metrics blobs also by source address, not just destination address. From Christoph Paasch. 21) Support 10G in generic phylib. From Andy Fleming. 22) Try to short-circuit GRO flow compares using device provided RX hash, if provided. From Tom Herbert.

net: introduce SO_BPF_EXTENSIONS

2014-01-19T03:08:58Z

For user space packet capturing libraries such as libpcap, there's currently only one way to check which BPF extensions are supported by the kernel, that is, commit aa1113d9f85d ("net: filter: return -EINVAL if BPF_S_ANC* operation is not supported"). For querying all extensions at once this might be rather inconvenient. Therefore, this patch introduces a new option which can be used as an argument for getsockopt(), and allows one to obtain information about which BPF extensions are supported by the current kernel. As David Miller suggests, we do not need to define any bits right now and status quo can just return 0 in order to state that this versions supports SKF_AD_PROTOCOL up to SKF_AD_PAY_OFFSET. Later additions to BPF extensions need to add their bits to the bpf_tell_extensions() function, as documented in the comment.
