The openvswitch code has gained support for calling into the nf-nat-ipv4/ipv6 modules, however those can be loadable modules in a configuration in which openvswitch is built-in, leading to link errors: net/built-in.o: In function `__ovs_ct_lookup': :(.text+0x2cc2c8): undefined reference to `nf_nat_icmp_reply_translation' :(.text+0x2cc66c): undefined reference to `nf_nat_icmpv6_reply_translation' The dependency on (!NF_NAT || NF_NAT) prevents similar issues, but NF_NAT is set to 'y' if any of the symbols selecting it are built-in, but the link error happens when any of them are modular. A second issue is that even if CONFIG_NF_NAT_IPV6 is built-in, CONFIG_NF_NAT_IPV4 might be completely disabled. This is unlikely to be useful in practice, but the driver currently only handles IPv6 being optional. This patch improves the Kconfig dependency so that openvswitch cannot be built-in if either of the two other symbols are set to 'm', and it replaces the incorrect #ifdef in ovs_ct_nat_execute() with two "if (IS_ENABLED())" checks that should catch all corner cases also make the code more readable. The same #ifdef exists ovs_ct_nat_to_attr(), where it does not cause a link error, but for consistency I'm changing it the same way. Signed-off-by:

OVS should call into CT NAT for packets of new expected connections only when the conntrack state is persisted with the 'commit' option to the OVS CT action. The test for this condition is doubly wrong, as the CT status field is ANDed with the bit number (IPS_EXPECTED_BIT) rather than the mask (IPS_EXPECTED), and due to the wrong assumption that the expected bit would apply only for the first (i.e., 'new') packet of a connection, while in fact the expected bit remains on for the lifetime of an expected connection. The 'ctinfo' value IP_CT_RELATED derived from the ct status can be used instead, as it is only ever applicable to the 'new' packets of the expected connection.

This fix adds a new reference counter (ref_netlink) for the struct ip_set. The other reference counter (ref) can be swapped out by ip_set_swap and we need a separate counter to keep track of references for netlink events like dump. Using the same ref counter for dump causes a race condition which can be demonstrated by the following script: ipset create hash_ip1 hash:ip family inet hashsize 1024 maxelem 500000 \ counters ipset create hash_ip2 hash:ip family inet hashsize 300000 maxelem 500000 \ counters ipset create hash_ip3 hash:ip family inet hashsize 1024 maxelem 500000 \ counters ipset save & ipset swap hash_ip3 hash_ip2 ipset destroy hash_ip3 /* will crash the machine */ Swap will exchange the values of ref so destroy will see ref = 0 instead of ref = 1. With this fix in place swap will not succeed because ipset save still has ref_netlink on the set (ip_set_swap doesn't swap ref_netlink). Both delete and swap will error out if ref_netlink != 0 on the set. Note: The changes to *_head functions is because previously we would increment ref whenever we called these functions, we don't do that anymore. Reviewed-by:

In ravb_start_xmit dont call skb_tx_timestamp only when hardware timestamping is requested: in the latter case software timestamps are suppressed and thus the call of skb_tx_timestamp does not have any effect. Instead call skb_tx_timestamp unconditionally in ravb_start_xmit, since the function checks itself if software timestamping is required or should be skipped due to hardware timestamping.

We need to use post-decrement to ensure that irq_dispose_mapping is also called on priv->rxq[0]->irq_no; moreover, if one of the above for loops failed already at i==0 (so we reach one of these labels with that value of i), we'll enter an essentially infinite loop of out-of-bounds accesses.

This patch removes two BUG_ON() used to notify about RX queue corruptions on macb (not gem) hardware without actually handling the error. The new code skips corrupted frames but still processes faultless frames. Then it resets the RX queue before restarting the reception from a clean state. This patch is a rework of an older patch proposed by Neil Armstrong: http://patchwork.ozlabs.org/patch/371525/Signed-off-by:

netpoll_setup() does a dev_hold() on np->dev, the netpoll device. If it fails, it correctly does a dev_put() but leaves np->dev set. If we call netpoll_cleanup() after the failure, np->dev is still set so we do another dev_put(), which decrements the refcount an extra time. It's questionable to call netpoll_cleanup() after netpoll_setup() fails, but it can be difficult to find the problem, and we can easily avoid it in this case. The extra decrements can lead to hangs like this: unregister_netdevice: waiting for bond0 to become free. Usage count = -3 Set and clear np->dev at the points where we dev_hold() and dev_put() the device. Signed-off-by:

skb_len needs to be skb_headlen(skb) in bcmgenet_xmit_single(). Fragmented skbs can have only Ethernet + IP + TCP headers (14+20+20=54 bytes) in the linear buffer, followed by the rest in fragments. Bumping skb_len to ETH_ZLEN would be incorrect for this case, as it would introduce garbage between TCP header and the fragment data. This also works with regular/non-fragmented small packets < ETH_ZLEN bytes. Successfully tested this on GENETv3 with 42-byte ARP frames. For testing, I used: ethtool -K eth0 tx-checksum-ipv4 off ethtool -K eth0 tx-checksum-ipv6 off echo 0 > /proc/sys/net/ipv4/tcp_timestamps Fixes: 1c1008c7 ("net: bcmgenet: add main driver file") Signed-off-by:

1. Add bytes_compl local variable to __bcmgenet_tx_reclaim() to collect transmitted bytes. dev->stats updates can then be moved outside the while-loop. bytes_compl is also needed for future BQL support. 2. When bcmgenet device uses Tx checksum offload, each transmitted skb gets an extra 64-byte header prepended to it. Before this header is prepended to the skb, we need to save the skb "wire" length in GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can be done in __bcmgenet_tx_reclaim(). 3. skb->len covers the entire length of skb, whether it is linear or fragmented. Thus, when we clean the fragments, do not increase transmitted bytes. Fixes: 1c1008c7 ("net: bcmgenet: add main driver file") Signed-off-by:

As is shown below: [0:0] ---> lane0 [1:1] ---> lane1 ... But the current driver reads the reg to get the hilink status ONLY concidering HNS V1 situation. Here is a patch to support both of them.

Merge tag 'perf-core-for-mingo-20160323' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/core improvements and fixes: User visible fixes: - Fix documentation of :ppp modifier in 'perf list' (Andi Kleen) - Fix silly nodes bitfield bits/bytes length assertion in 'perf bench numa' (Jakub Jelen) - Remove redundant CPU output in libtraceevent (Steven Rostedt) - Remove 'core_id' check in topology 'perf test' (Sukadev Bhattiprolu) Infrastructure changes/fixes: - Record text offset in dso to calculate objdump address, to use with modules in addition to vDSO symbol address calculations (Wang Nan) - Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo) - Add cpumode to the perf_sample struct, this way we don't need to pass the union event to the machine and thread resolving routines, shortening function signatures and allowing the future introduction of a way to use tracepoint events instead of the unavailable HW cycles counter on powerpc guests in perf kvm by just hooking on perf_evsel__parse_sample, at the end (Arnaldo Carvalho de Melo) - Remove/unexport die() related infrastructure, that at some point will finally be removed (Arnaldo Carvalho de Melo) - Adopt linux/stringify.h from the kernel sources, not to touch this kernel header from tools/ (Arnaldo Carvalho de Melo) - Stop using strbuf for things we can instead trivially use libc's asprintf() (Arnaldo Carvalho de Melo) - Ditch tools/lib/util/abspath.c, its only exported function was used at just one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo) - Use strerror_r() in the llvm infrastructure, tread safe, its what is used elsewhere in tools/perf/ (Arnaldo Carvalho de Melo) Cleanups: - Removed misplaced or needless __maybe_unused/export (Arnaldo Carvalho de Melo) Signed-off-by:

As ping_v6_sendmsg is used only in this file, making it static The body of "pingv6_prot" and "pingv6_protosw" were moved at the middle of the file, to avoid having to declare some static prototypes. Signed-off-by:

Reorder the code in netvsc_sc_open(), so num_sc_offered is only decremented after vmbus_open() is called. This avoid pontential race of removing device before all channels are setup. Signed-off-by:
