net_sched: act_gact: remove spinlock in fast path
Final step for gact RCU operation : 1) Use percpu stats 2) update lastuse only every clock tick to avoid false sharing 3) Remove spinlock acquisition, as it is no longer needed. Since this is the last contended lock in packet RX when tc gact is used, this gives impressive gain. My host with 8 RX queues was handling 5 Mpps before the patch, and more than 11 Mpps after patch. Tested: On receiver : dev=eth0 tc qdisc del dev $dev ingress 2>/dev/null tc qdisc add dev $dev ingress tc filter del dev $dev root pref 10 2>/dev/null tc filter del dev $dev pref 10 2>/dev/null tc filter add dev $dev est 1sec 4sec parent ffff: protocol ip prio 1 \ u32 match ip src 7.0.0.0/8 flowid 1:15 action drop Sender sends packets flood from 7/8 network Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Alexei Starovoitov <ast@plumgrid.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Acked-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: David S.

net_sched: act_gact: use a separate packet counters for gact_determ()
Second step for gact RCU operation : We want to get rid of the spinlock protecting gact operations.

net_sched: act_gact: make tcfg_pval non zero
First step for gact RCU operation : Instead of testing if tcfg_pval is zero or not, just make it 1. No change in behavior, but slightly faster code.

Merge branch 'tcp-policer-drops'
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: David S.

tcp: PRR uses CRB mode by default and SS mode conditionally
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.

tcp: reduce cwnd if retransmit is lost in CA_Loss
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.

cxgb4: Fix incorrect sequence numbers shown in devlog
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.

enic: fix issues in enic_poll
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 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"

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

IOMMU Fixes for Linux v4.2-rc0
Four fixes have queued up to fix regressions introduced after v4.1:
* Don't fail IOMMU driver initialization when the add_device
call-back returns -ENODEV, as that just means that the device
is not translated by the IOMMU. This is pretty common on ARM.
* Two fixes for the ARM-SMMU driver for a wrong feature check
and to remove a redundant NULL check.
* A fix for the AMD IOMMU driver to fix a boot panic on systems
where the BIOS requests Unity Mappings in the IVRS table.

Merge tag 'iommu-fixes-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pul IOMMU fixes from Joerg Roedel:
"Four fixes have queued up to fix regressions introduced after v4.1:
- Don't fail IOMMU driver initialization when the add_device
call-back returns -ENODEV, as that just means that the device is
not translated by the IOMMU. This is pretty common on ARM.
- Two fixes for the ARM-SMMU driver for a wrong feature check and to
remove a redundant NULL check.
- A fix for the AMD IOMMU driver to fix a boot panic on systems where
the BIOS requests Unity Mappings in the IVRS table"

Minor merge needed, due to function move.
Main excitement here is Peter Zijlstra's lockless rbtree optimization to
speed module address lookup. He found some abusers of the module lock
doing that too.
A little bit of parameter work here too; including Dan Streetman's breaking
up the big param mutex so writing a parameter can load another module (yeah,
really). Unfortunately that broke the usual suspects, !CONFIG_MODULES and
!CONFIG_SYSFS, so those fixes were appended too.
Cheers,
Rusty.

be used for inode allocation when free space is fragmented.
o DAX support. This includes minor changes to the DAX core code to
fix problems with lock ordering and bufferhead mapping abuse.
o transaction commit interface cleanup
o removal of various unnecessary XFS specific type definitions
o cleanup and optimisation of freelist preparation before allocation
o various minor cleanups
o bug fixes for
- transaction reservation leaks
- incorrect inode logging in unwritten extent conversion
- mmap lock vs freeze ordering
- remote symlink mishandling
- attribute fork removal issues.

Pull btrfs updates from Chris Mason: "Outside of our usual batch of fixes, this integrates the subvolume quota updates that Qu Wenruo from Fujitsu has been working on for a few releases now. He gets an extra gold star for making btrfs smaller this time, and fixing a number of quota corners in the process. Dave Sterba tested and integrated Anand Jain's sysfs improvements. Outside of exporting a symbol (ack'd by Greg) these are all internal to btrfs and it's mostly cleanups and fixes. Anand also attached some of our sysfs objects to our internal device management structs instead of an object off the super block. It will make device management easier overall and it's a better fit for how the sysfs files are used. None of the existing sysfs files are moved around. Thanks for all the fixes everyone" * 'for-linus-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (87 commits) btrfs: delayed-ref: double free in btrfs_add_delayed_tree_ref() Btrfs: Check if kobject is initialized before put lib: export symbol kobject_move() Btrfs: sysfs: add support to show replacing target in the sysfs Btrfs: free the stale device Btrfs: use received_uuid of parent during send Btrfs: fix use-after-free in btrfs_replay_log btrfs: wait for delayed iputs on no space btrfs: qgroup: Make snapshot accounting work with new extent-oriented qgroup. btrfs: qgroup: Add the ability to skip given qgroup for old/new_roots. btrfs: ulist: Add ulist_del() function. btrfs: qgroup: Cleanup the old ref_node-oriented mechanism. btrfs: qgroup: Switch self test to extent-oriented qgroup mechanism. btrfs: qgroup: Switch to new extent-oriented qgroup mechanism. btrfs: qgroup: Switch rescan to new mechanism. btrfs: qgroup: Add new qgroup calculation function btrfs_qgroup_account_extents(). btrfs: backref: Add special time_seq == (u64)-1 case for btrfs_find_all_roots(). btrfs: qgroup: Add new function to record old_roots. btrfs: qgroup: Record possible quota-related extent for qgroup. btrfs: qgroup: Add function qgroup_update_counters(). ... |
