When packet encapsulation is in use, the MTU needs to be reduced for headroom reservation. The existing code takes the updated MTU value only from the host side. But vSwitch extensions, such as Open vSwitch, require the flexibility to change the MTU to different values from within a guest during the lifecycle of a vNIC, when the encapsulation protocol is changed. The patch supports this kind of MTU changes. Signed-off-by: NHaiyang Zhang <haiyangz@microsoft.com> Reviewed-by: NK. Y. Srinivasan <kys@microsoft.com> Signed-off-by: NDavid S.

Yuchung Cheng says: ==================== tcp: reducing lost retransmits in recovery This patch series reduces lost retransmits in recovery, in particular when dealing with traffic policers. The main problem is that slow start in recovery under policing can cause massive lost and retransmit storms: any excess sending rate turns into drops. The solution is to avoid doing slow start when lost retransmit is detected and use packet conservation instead. On networks with traffic policers the patches have lowered the TCP loss rates by ~20% from Google servers without latency regressions. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

PRR slow start is often too aggressive especially when drops are caused by traffic policers. The policers mainly use token bucket to enforce the rate so sending (twice) faster than the delivery rate causes excessive drops. This patch changes PRR to the conservative reduction bound (CRB) mode in RFC 6937 by default. CRB follows the packet conservation rule to send at most the delivery rate by default. But if many packets are lost and the pipe is empty, CRB may take N round trips to repair N losses. We conditionally turn on slow start mode if all these conditions are made to speed up the recovery: 1) on the second round or later in recovery 2) retransmission sent in the previous round is delivered on this ACK 3) no retransmission is marked lost on this ACK By using packet conservation by default, this change reduces the loss retransmits signicantly on networks that deploy traffic policers, up to 20% reduction of overall loss rate.

If the retransmission in CA_Loss is lost again, we should not continue to slow start or raise cwnd in congestion avoidance mode. Instead we should enter fast recovery and use PRR to reduce cwnd, following the principle in RFC5681: "... or the loss of a retransmission, should be taken as two indications of congestion and, therefore, cwnd (and ssthresh) MUST be lowered twice in this case." This is especially important to reduce loss when the CA_Loss state was caused by a traffic policer dropping the entire inflight. The CA_Loss state has a problem where a loss of L packets causes the sender to send a burst of L packets. So a policer that's dropping most packets in a given RTT can cause a huge retransmit storm. By contrast, PRR includes logic to bound the number of outbound packets that result from a given ACK. So switching to CA_Recovery on lost retransmits in CA_Loss avoids this retransmit storm problem when in CA_Loss.

In this window if an irq occurs and napi is scheduled on different cpu, it tries to acquire enic_poll_lock_napi() and fails.

We see an increasing number of non-modular drivers using modular_driver() type register functions. There are several downsides to letting this continue unchecked: - The code can appear modular to a reader of the code, and they won't know if the code really is modular without checking the Makefile and Kconfig to see if compilation is governed by a bool or tristate. - Coders of drivers may be tempted to code up an __exit function that is never used, just in order to satisfy the required three args of the modular registration function. - Non-modular code ends up including the <module.h> which increases CPP overhead that they don't need. - It hinders us from performing better separation of the module init code and the generic init code. So here we introduce similar macros for builtin drivers. Then we convert builtin drivers (controlled by a bool Kconfig) by making the following type of mapping: module_platform_driver() ---> builtin_platform_driver() module_platform_driver_probe() ---> builtin_platform_driver_probe(). The set of drivers that are converted here are just the ones that showed up as relying on an implicit include of <module.h> during a pending header cleanup. So we convert them here vs adding an include of <module.h> to non-modular code to avoid compile fails. Additonal conversions can be done asynchronously at any time.

This series converts non-modular code that is using the module_init() call to hook itself into the system to instead use one of our alternate priority initcalls. Unlike the previous series that used device_initcall and hence was a runtime no-op, these commits change to one of the alternate initcalls, because (a) we have them and (b) it seems like the right thing to do. For example, it would seem logical to use arch_initcall for arch specific setup code and fs_initcall for filesystem setup code. This does mean however, that changes in the init ordering will be taking place, and so there is a small risk that some kind of implicit init ordering issue may lie uncovered. But I think it is still better to give these ones sensible priorities than to just assign them all to device_initcall in order to exactly preserve the old ordering. Thad said, we have already made similar changes in core kernel code in commit c96d6660 ("kernel: audit/fix non-modular users of module_init in core code") without any regressions reported, so this type of change isn't without precedent.

We fix them up now, so that we can decouple some of the module related init code from the core init code in the future. The addition of the module.h include to several files here is also a no-op from a code generation point of view, else there would already be compile issues with these files today. There may be lots more implicit includes of <module.h> in tree, but these are the ones that extensive build test coverage has shown that must be fixed in order to avoid build breakage fallout for the pending module.h <---> init.h code relocation we desire to complete" * tag 'module-implicit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: frv: add module.h to mb93090-mb00/flash.c to avoid compile fail drivers/cpufreq: include <module.h> for modular exynos-cpufreq.c code drivers/staging: include <module.h> for modular android tegra_ion code crypto/asymmetric_keys: pkcs7_key_type needs module.h sh: mach-highlander/psw.c is tristate and should use module.h drivers/regulator: include <module.h> for modular max77802 code drivers/pcmcia: include <module.h> for modular xxs1500_ss code drivers/hsi: include <module.h> for modular omap_ssi code drivers/gpu: include <module.h> for modular rockchip code drivers/gpio: include <module.h> for modular crystalcove code drivers/clk: include <module.h> for clk-max77xxx modular code

Pull __cpuinit removal from Paul Gortmaker: "Remove __cpuinit macros and users. We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a273 ("init.h: remove __cpuinit sections from the kernel") but we left some no-op stubs as a courtesy to unmerged code. Here we get rid of the stubs as well, since (as can be seen in these changes) they are enabling use cases to sneak back in, primarily from older BSP code that has been living out of tree for some time prior to getting mainlined. So we get rid of these "new" users 1st and then get rid of the stubs. Obviously, getting rid of the stubs can't happen until all the users are gone, so I had to keep this together as a series, even though some of these commits since got picked up into maintainers trees as well. The nature of this change is such that it should have zero impact on the generated runtime. This is one of several independent cleanup branches aimed at enabling better organization in the init.h and module.h code. They have been getting coverage in the linux-next tree for the last month, in addition to my local testing, which also covers approximately a half dozen or more architectures" * tag 'cpuinit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: init: delete the __cpuinit related stubs kernel/cpu.c: remove new instance of __cpuinit that crept back in sched/core: remove __cpuinit section tag that crept back in. mips/mm/tlbex: remove new instance of __cpuinit that crept back in mips/c-r4k: remove legacy __cpuinit section that crept in mips/bcm77xx: remove legacy __cpuinit sections that crept in mips/ath25: remove legacy __cpuinit section that crept in arm/mach-hisi: remove legacy __CPUINIT section that crept in arm/mach-rockchip: remove legacy __cpuinit section that crept in arm/mach-mvebu: remove legacy __cpuinit sections that crept in arm/mach-keystone: remove legacy __cpuinit sections that crept in
