2014-10-01bnx2: Correctly receive full sized 802.1ad fragmesVlad Yasevich
This driver, similar to tg3, has a check that will cause full sized 802.1ad frames to be dropped. The frame will be larger then the standard mtu due to the presense of vlan header that has not been stripped. The driver should not drop this frame and should process it just like it does for 802.1q.

2014-10-01tg3: Allow for recieve of full-size 8021AD framesVlad Yasevich
When receiving a vlan-tagged frame that still contains a vlan header, the length of the packet will be greater then MTU+ETH_HLEN since it will account of the extra vlan header. TG3 checks this for the case for 802.1Q, but not for 802.1ad. As a result, full sized 802.1ad frames get dropped by the card. Add a check for 802.1ad protocol when receving full sized frames.

2014-09-30nfsd4: fix corruption of NFSv4 read dataJ. Bruce Fields
The calculation of page_ptr here is wrong in the case the read doesn't start at an offset that is a multiple of a page. The result is that nfs4svc_encode_compoundres sets rq_next_page to a value one too small, and then the loop in svc_free_res_pages may incorrectly fail to clear a page pointer in rq_respages[]. Pages left in rq_respages[] are available for the next rpc request to use, so xdr data may be written to that page, which may hold data still waiting to be transmitted to the client or data in the page cache. The observed result was silent data corruption seen on an NFSv4 client. We tag this as "fixing" 05638dc73af2 because that commit exposed this bug, though the incorrect calculation predates it. Particular thanks to Andrea Arcangeli and David Gilbert for analysis and testing.

2014-09-30ipv6: remove rt6i_genidHannes Frederic Sowa
Eric Dumazet noticed that all no-nonexthop or no-gateway routes which are already marked DST_HOST (e.g. input routes routes) will always be invalidated during sk_dst_check. Thus per-socket dst caching absolutely had no effect and early demuxing had no effect. Thus this patch removes rt6i_genid: fn_sernum already gets modified during add operations, so we only must ensure we mutate fn_sernum during ipv6 address remove operations. This is a fairly cost extensive operations, but address removal should not happen that often. Also our mtu update functions do the same and we heard no complains so far. xfrm policy changes also cause a call into fib6_flush_trees. Also plug a hole in rt6_info (no cacheline changes). I verified via tracing that this change has effect.

2014-09-30ARM: 8179/1: kprobes-test: Fix compile error "bad immediate value for offset"Jon Medhurst
When compiling kprobes-test-arm.c the following error has been observed /tmp/ccoT403o.s:21439: Error: bad immediate value for offset (4168) This is caused by the compiler spilling it's literal pool too far away from the site which is trying to reference it with a PC relative load. This arises because the compiler is underestimating the size of the inline assembler code present, which apparently it approximates as 4 bytes per line or instruction. We fix this problem by moving the operations which generate more than 4 bytes out of the text section. Specifically, moving the .ascii directives to the .rodata section.

2014-09-30ACPI / i915: Update the condition to ignore firmware backlight change requestAaron Lu
Some of the Thinkpads' firmware will issue a backlight change request through i915 operation region unconditionally on AC plug/unplug, the backlight level used is arbitrary and thus should be ignored. This is handled by commit 0b9f7d93ca61 (ACPI / i915: ignore firmware requests for backlight change). Then there is a Dell laptop whose vendor backlight interface also makes use of operation region to change backlight level and with the above commit, that interface no long works. The condition used to ignore the backlight change request from firmware is thus changed to: if the vendor backlight interface is not in use and the ACPI backlight interface is broken, we ignore the requests; oterwise, we keep processing them.

2014-09-29cpufreq: integrator: fix integrator_cpufreq_remove return typeArnd Bergmann
When building this driver as a module, we get a helpful warning about the return type: drivers/cpufreq/integrator-cpufreq.c:232:2: warning: initialization from incompatible pointer type .remove = __exit_p(integrator_cpufreq_remove), If the remove callback returns void, the caller gets an undefined value as it expects an integer to be returned. This fixes the problem by passing down the value from cpufreq_unregister_driver. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: All applicable <stable@vger.kernel.org> Signed-off-by: Rafael J.

Steffen Klassert says: ==================== ipv6: Return an error when adding an already existing tunnel The ipv6 tunnel locate functions should not return an existing tunnel if create is true. Otherwise it is possible to add the same tunnel multiple times without getting an error. All our ipv6 tunnels have this bug from the very beginning. Only the sit tunnel was fixed some years ago with: commit 8db99e57175 ("sit: Fail to create tunnel, if it already exists"). This patchset fixes the remaining ipv6 tunnels. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
