2016-02-236lowpan: iphc: add support for stateful compressionAlexander Aring
This patch introduce support for IPHC stateful address compression. It will offer the context table via one debugfs entry. This debugfs has and directory for each cid entry for the context table. Inside each cid directory there exists the following files: - "active": If the entry is added or deleted. The context table is original a list implementation, this flag will indicate if the context is part of list or not. - "prefix": The ipv6 prefix. - "prefix_length": The prefix length for the prefix. - "compression": The compression flag according RFC6775. This part should be moved into sysfs after some testing time. Also the debugfs entry contains a "show" file which is a pretty-printout for the current context table information.

2016-02-23mac802154: fix mac header length checkAlexander Aring
I got report about that sometimes the WARN_ON occurs there which should never happen. I came to the conclusion that the mac header is there but inside the headroom of skb. The skb->len information doesn't contain the information about the headroom length and skb->len is lesser than two. We check now if the skb_mac_header pointer is set and the room between mac header pointer and tail pointer.

2016-02-21net: ethernet: davicom: fix devicetree irq resourceRobert Jarzmik
The dm9000 driver doesn't work in at least one device-tree configuration, spitting an error message on irq resource : [    1.062495] dm9000 8000000.ethernet: insufficient resources [    1.068439] dm9000 8000000.ethernet: not found (-2). [    1.073451] dm9000: probe of 8000000.ethernet failed with error -2 The reason behind is that the interrupt might be provided by a gpio controller, not probed when dm9000 is probed, and needing the probe deferral mechanism to apply. Currently, the interrupt is directly taken from resources. This patch changes this to use the more generic platform_get_irq(), which handles the deferral. Moreover, since commit Fixes: 7085a7401ba5 ("drivers: platform: parse IRQ flags from resources"), the interrupt trigger flags are honored in platform_get_irq(), so remove the needless code in dm9000.

2016-02-21bpf: don't emit mov A,A on returnDaniel Borkmann
While debugging with bpf_jit_disasm I noticed emissions of 'mov %eax,%eax', and found that this comes from BPF_RET | BPF_A translations from classic BPF. Emitting this is unnecessary as BPF_REG_A is mapped into BPF_REG_0 already, therefore only emit a mov when immediates are used as return value.

2016-02-21bpf: fix csum update in bpf_l4_csum_replace helper for udpDaniel Borkmann
When using this helper for updating UDP checksums, we need to extend this in order to write CSUM_MANGLED_0 for csum computations that result into 0 as sum. Reason we need this is because packets with a checksum could otherwise become incorrectly marked as a packet without a checksum. Likewise, if the user indicates BPF_F_MARK_MANGLED_0, then we should not turn packets without a checksum into ones with a checksum.

2016-02-21bpf: try harder on clones when writing into skbDaniel Borkmann
When we're dealing with clones and the area is not writeable, try harder and get a copy via pskb_expand_head(). Replace also other occurences in tc actions with the new skb_try_make_writable().
