2012-04-03af_unix: reduce high order page allocationsEric Dumazet
unix_dgram_sendmsg() currently builds linear skbs, and this can stress page allocator with high order page allocations. When memory gets fragmented, this can eventually fail. We can try to use order-2 allocations for skb head (SKB_MAX_ALLOC) plus up to 16 page fragments to lower pressure on buddy allocator. This patch has no effect on messages of less than 16064 bytes. (on 64bit arches with PAGE_SIZE=4096) For bigger messages (from 16065 to 81600 bytes), this patch brings reliability at the expense of performance penalty because of extra pages allocations. netperf -t DG_STREAM -T 0,2 -- -m 16064 -s 200000 ->4086040 Messages / 10s netperf -t DG_STREAM -T 0,2 -- -m 16068 -s 200000 ->3901747 Messages / 10s Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

Pull networking fixes from David Miller: 1) Provide device string properly for USB i2400m wimax devices, also don't OOPS when providing firmware string. From Phil Sutter. 2) Add support for sh_eth SH7734 chips, from Nobuhiro Iwamatsu. 3) Add another device ID to USB zaurus driver, from Guan Xin. 4) Loop index start in pool vector iterator is wrong causing MAC to not get configured in bnx2x driver, fix from Dmitry Kravkov. 5) EQL driver assumes HZ=100, fix from Eric Dumazet. 6) Now that skb_add_rx_frag() can specify the truesize increment separately, do so in f_phonet and cdc_phonet, also from Eric Dumazet. 7) virtio_net accidently uses net_ratelimit() not only on the kernel warning but also the statistic bump, fix from Rick Jones. 8) ip_route_input_mc() uses fixed init_net namespace, oops, use dev_net(dev) instead. Fix from Benjamin LaHaise. 9) dev_forward_skb() needs to clear the incoming interface index of the SKB so that it looks like a new incoming packet, also from Benjamin LaHaise. 10) iwlwifi mistakenly initializes a channel entry as 2GHZ instead of 5GHZ, fix from Stanislav Yakovlev. 11) Missing kmalloc() return value checks in orinoco, from Santosh Nayak. 12) ath9k doesn't check for HT capabilities in the right way, it is checking ht_supported instead of the ATH9K_HW_CAP_HT flag. Fix from Sujith Manoharan. 13) Fix x86 BPF JIT emission of 16-bit immediate field of AND instructions, from Feiran Zhuang. 14) Avoid infinite loop in GARP code when registering sysfs entries. From David Ward. 15) rose protocol uses memcpy instead of memcmp in a device address comparison, oops. Fix from Daniel Borkmann. 16) Fix build of lpc_eth due to dev_hw_addr_rancom() interface being renamed to eth_hw_addr_random(). From Roland Stigge. 17) Make ipv6 RTM_GETROUTE interpret RTA_IIF attribute the same way that ipv4 does. Fix from Shmulik Ladkani. 18) via-rhine has an inverted bit test, causing suspend/resume regressions. Fix from Andreas Mohr. 19) RIONET assumes 4K page size, fix from Akinobu Mita. 20) Initialization of imask register in sky2 is buggy, because bits are "or'd" into an uninitialized local variable. Fix from Lino Sanfilippo. 21) Fix FCOE checksum offload handling, from Yi Zou. 22) Fix VLAN processing regression in e1000, from Jiri Pirko. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (52 commits) sky2: dont overwrite settings for PHY Quick link tg3: Fix 5717 serdes powerdown problem net: usb: cdc_eem: fix mtu net: sh_eth: fix endian check for architecture independent usb/rtl8150 : Remove duplicated definitions rionet: fix page allocation order of rionet_active via-rhine: fix wait-bit inversion. ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4 net: lpc_eth: Fix rename of dev_hw_addr_random net/netfilter/nfnetlink_acct.c: use linux/atomic.h rose_dev: fix memcpy-bug in rose_set_mac_address Fix non TBI PHY access; a bad merge undid bug fix in a previous commit. net/garp: avoid infinite loop if attribute already exists x86 bpf_jit: fix a bug in emitting the 16-bit immediate operand of AND bonding: emit event when bonding changes MAC mac80211: fix oper channel timestamp updation ath9k: Use HW HT capabilites properly MAINTAINERS: adding maintainer for ipw2x00 net: orinoco: add error handling for failed kmalloc(). net/wireless: ipw2x00: fix a typo in wiphy struct initilization ...
2012-04-02openvswitch: Add length check when retrieving TCP flags.Jesse Gross
When collecting TCP flags we check that the IP header indicates that a TCP header is present but not that the packet is actually long enough to contain the header. This adds a check to prevent reading off the end of the packet. In practice, this is only likely to result in reading of bad data and not a crash due to the presence of struct skb_shared_info at the end of the packet. Signed-off-by: Jesse Gross <jesse@nicira.com>
2012-04-02net: Report dev->promiscuity in netlink reports.Ben Greear
The standard ways of probing a device's promiscuity (ifi_flags, for instance) does not report the actual state of the device. This patch adds dev->promiscuity to the netlink netdevice report so that users can know for certain if the device is acting PROMISC or not.

2012-04-01ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4Shmulik Ladkani
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE message, then a route is searched as if a packet was received on the specified 'iif' interface. However in IPv6, RTA_IIF is not interpreted in the same way: 'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the RTA_IIF attribute. As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look for a route as if a packet was received on a specific interface. Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a route as if a packet was received on the specified interface", similar to IPv4's 'inet_rtm_getroute()' interpretation.
