2014-12-05sky2: avoid pci write posting after disabling irqsLino Sanfilippo
In sky2_change_mtu setting B0_IMSK to 0 may be delayed due to PCI write posting which could result in irqs being still active when synchronize_irq is called. Since we are not prepared to handle any further irqs after synchronize_irq (our resources are freed after that) force the write by a consecutive read from the same register. Similar situation in sky2_all_down: Here we disabled irqs by a write to B0_IMSK but did not ensure that this write took place before synchronize_irq. Fix that too.

2014-12-05pxa168: close race between napi and irq activationLino Sanfilippo
In pxa168_eth_open() the irqs are enabled before napi. This opens a tiny time window in which the irq handler is processed, disables irqs but then is not able to schedule the not yet activated napi, leaving irqs disabled forever (since irqs are reenabled in napi poll function). Fix this race by activating napi before irqs are activated. Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-12-05bpf: x86: fix epilogue generation for eBPF programsAlexei Starovoitov
classic BPF has a restriction that last insn is always BPF_RET. eBPF doesn't have BPF_RET instruction and this restriction. It has BPF_EXIT insn which can appear anywhere in the program one or more times and it doesn't have to be last insn. Fix eBPF JIT to emit epilogue when first BPF_EXIT is seen and all other BPF_EXIT instructions will be emitted as jump. Since jump offset to epilogue is computed as: jmp_offset = ctx->cleanup_addr - addrs[i] we need to change type of cleanup_addr to signed to compute the offset as: (long long) ((int)20 - (int)30) instead of: (long long) ((unsigned int)20 - (int)30) Fixes: 622582786c9e ("net: filter: x86: internal BPF JIT") Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following batch contains netfilter updates for net-next. Basically, enhancements for xt_recent, skip zeroing of timer in conntrack, fix linking problem with recent redirect support for nf_tables, ipset updates and a couple of cleanups. More specifically, they are: 1) Rise maximum number per IP address to be remembered in xt_recent while retaining backward compatibility, from Florian Westphal. 2) Skip zeroing timer area in nf_conn objects, also from Florian. 3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using using meta l4proto and transport layer header, from Alvaro Neira. 4) Fix linking problems in the new redirect support when CONFIG_IPV6=n and IP6_NF_IPTABLES=n. And ipset updates from Jozsef Kadlecsik: 5) Support updating element extensions when the set is full (fixes netfilter bugzilla id 880). 6) Fix set match with 32-bits userspace / 64-bits kernel. 7) Indicate explicitly when /0 networks are supported in ipset. 8) Simplify cidr handling for hash:*net* types. 9) Allocate the proper size of memory when /0 networks are supported. 10) Explicitly add padding elements to hash:net,net and hash:net,port, because the elements must be u32 sized for the used hash function.

Then cleans up the tail writes for the ixgbe descriptor queues. Mark Peterson adds support to lookup MAC addresses in Open Firmware or IDPROM. Emil provides patches for ixgbe and ixgbevf to fix an issue on rmmod and to add support for X550 in the VF driver. First removes the read/write operations to the CIAA/D registers since it can block access to the PCI config space and make use of standard kernel functions for accessing the PCI config space. Then fixes an issue where the driver has logic to free up used data in case any of the checks in ixgbe_probe() fail, however there is a similar set of cleanups that can occur on driver unload in ixgbe_remove() which can cause the rmmod command to crash. Don provides the remaining patches in the series to complete the addition of X550 support into the ixgbe driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-12-05ixgbe: Clean-up page reuse codeAlexander Duyck
This patch cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. It also cleans up how we clear the descriptor status bits. Previously they were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a 64 bit field and 64 bit writes can be a bit more expensive on on 32 bit systems. Since we are no longer using the header split feature the upper 32 bits of the address no longer need to be cleared. As a result we can just clear the status bits and leave the length and VLAN fields as-is which should provide more information in debugging.
