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.

Part of commit 49aa284fe64c4c1 ("cxgb4: Add support for devlog") change introduced a real bug where the Device Log Sequence Numbers are no longer being converted from firmware Big-Endian to local CPU-Endian format. This patch moves all of the translation into the devlog_show() routine. The only endianness code now in devlog_open() is the small loop to find the earliest (lowest Sequence Number) Device Log entry in the circular buffer.

Johan Hedberg says: ==================== pull request: bluetooth 2015-07-02 A couple of regressions crept in because of a patch to use proper list APIs rather than manually reading & writing the next/prev pointers (commit 835a6a2f). Turns out this was masking a few bugs: a missing INIT_LIST_HEAD() call and incorrectly using list_del() rather than list_del_init(). The two patches in this set fix these, and it'd be nice they could still make it to 4.2-rc1 to avoid new bug reports from users. Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In enic_poll, we clean tx and rx queues, when low latency busy socket polling is happening, enic_poll will only clean tx queue. After cleaning tx, it should return total budget for re-poll. There is a small window between vnic_intr_unmask() and enic_poll_unlock_napi(). In this window if an irq occurs and napi is scheduled on different cpu, it tries to acquire enic_poll_lock_napi() and fails. Unlock napi_poll before unmasking the interrupt. v2: Do not change tx wonk done behaviour. Consider only rx work done for completing napi.

Pull init.h/module.h fragility fixes from Paul Gortmaker: "Fixup various init.h misuses that are fragile wrt code moving to module.h What started as a removal of no longer required include <linux/init.h> due to the earlier __cpuinit and __devinit removal led to the observation that some module specfic support was living in init.h itself, thus preventing the full removal from introducing compile regressions. This series includes a few final fixups needed prior to the relocation of the modular init code from <init.h> to <module.h>. These are things that weren't easily categorized into any of the other previous series categories already requested for pull. That said, each fixup branch (including this one) is independent and there are no ordering constraints.

Merge tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_platform_driver replacement from Paul Gortmaker: "Replace module_platform_driver with builtin_platform driver in non modules. 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. Once again, an unused module_exit function that is removed here appears in the diffstat as an outlier wrt all the other changes" * tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver drivers/cpufreq: Convert non-modular s5pv210-cpufreq.c to use builtin_platform_driver drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driver drivers/platform: Convert non-modular pdev_bus to use builtin_platform_driver platform_device: better support builtin boilerplate avoidance

Merge tag 'module_init-alternate_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_init replacement part two from Paul Gortmaker: "Replace module_init with appropriate alternate initcall in non modules. 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. It has also got the same local testing and linux-next coverage as all the other pull requests that I'm sending for this merge window have got.

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.
