      kselftests/net: adapt the timeout to the largest runtime · de0e4447
      Li Zhijian authored 
      timeout in settings is used by each case under the same directory, so
it should adapt to the maximum runtime.

A normally running net/fib_nexthops.sh may be killed by this unsuitable
timeout. Furthermore, since the defect[1] of kselftests framework,
net/fib_nexthops.sh which might take at least (300 * 4) seconds would
block the whole kselftests framework previously.
$ git grep -w 'sleep 300' tools/testing/selftests/net
tools/testing/selftests/net/fib_nexthops.sh:    sleep 300
tools/testing/selftests/net/fib_nexthops.sh:    sleep 300
tools/testing/selftests/net/fib_nexthops.sh:    sleep 300
tools/testing/selftests/net/fib_nexthops.sh:    sleep 300

Enlarge the timeout by plus 300 based on the obvious largest runtime
to avoid the blocking.

      net: mscc: ocelot: don't let phylink re-enable TX PAUSE on the NPI port · 33cb0ff3
      Vladimir Oltean authored 
      Since commit b3964807 ("net: mscc: ocelot: disable flow control on
NPI interface"), flow control should be disabled on the DSA CPU port
when used in NPI mode.

However, the commit blamed in the Fixes: tag below broke this, because
it allowed felix_phylink_mac_link_up() to overwrite SYS_PAUSE_CFG_PAUSE_ENA
for the DSA CPU port.

This issue became noticeable since the device tree update from commit
8fcea7be ("arm64: dts: ls1028a: mark internal links between Felix
and ENETC as capable of flow control").

The solution is to check whether this is the currently configured NPI
port from ocelot_phylink_mac_link_up(), and to not modify the statically
disabled PAUSE frame transmission if it is.

When the port is configured for lossless mode as opposed to tail drop
mode, but the link partner (DSA master) doesn't observe the transmitted
PAUSE frames, the switch termination throughput is much worse, as can be
seen below.

      sch_api: Don't skip qdisc attach on ingress · de2d807b
      Maxim Mikityanskiy authored 
      The attach callback of struct Qdisc_ops is used by only a few qdiscs:
mq, mqprio and htb. qdisc_graft() contains the following logic
(pseudocode):

    if (!qdisc->ops->attach) {
        if (ingress)
            do ingress stuff;
        else
            do egress stuff;
    }
    if (!ingress) {
        ...
        if (qdisc->ops->attach)
            qdisc->ops->attach(qdisc);
    } else {
        ...
    }

As we see, the attach callback is not called if the qdisc is being
attached to ingress (TC_H_INGRESS). That wasn't a problem for mq and
mqprio, since they contain a check that they are attached to TC_H_ROOT,
and they can't be attached to TC_H_INGRESS anyway.

However, the commit cited below added the attach callback to htb. It is
needed for the hardware offload, but in the non-offload mode it
simulates the "do egress stuff" part of the pseudocode above. The
problem is that when htb is attached to ingress, neither "do ingress
stuff" nor attach() is called. It results in an inconsistency, and the
following message is printed to dmesg:

unregister_netdevice: waiting for lo to become free. Usage count = 2

This commit addresses the issue by running "do ingress stuff" in the
ingress flow even in the attach callback is present, which is fine,
because attach isn't going to be called afterwards.

The bug was found by syzbot and reported by Eric.

 "The most signigicant change here is the addition of a new cpufreq

  There are also other cpufreq updates (in the core, intel_pstate, ARM
  drivers), PM core updates (mostly related to adding new macros for
  declaring PM operations which should make the lives of driver
  developers somewhat easier), and a bunch of assorted fixes and
  cleanups.

  Summary:

   - Add new P-state driver for AMD processors (Huang Rui).

   - Fix initialization of min and max frequency QoS requests in the
     cpufreq core (Rafael Wysocki).

   - Fix EPP handling on Alder Lake in intel_pstate (Srinivas

   - Make intel_pstate update cpuinfo.max_freq when notified of HWP
     capabilities changes and drop a redundant function call from that
     driver (Rafael Wysocki).

   - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
     Stephen Boyd, Vladimir Zapolskiy).

   - Fix double devm_remap() in the Mediatek cpufreq driver (Hector
     Yuan).

   - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz
     Luba).

   - Make cpufreq use default_groups in kobj_type (Greg Kroah-Hartman).

   - Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).

   - Fix two comments in cpuidle code (Jason Wang, Yang Li).

   - Allow model-specific normal EPB value to be used in the intel_epb
     sysfs attribute handling code (Srinivas Pandruvada).

   - Simplify locking in pm_runtime_put_suppliers() (Rafael Wysocki).

   - Add safety net to supplier device release in the runtime PM core
     code (Rafael Wysocki).

   - Capture device status before disabling runtime PM for it (Rafael
     Wysocki).

   - Add new macros for declaring PM operations to allow drivers to
     avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
     update some drivers to use these macros (Paul Cercueil).

   - Allow ACPI hardware signature to be honoured during restore from
     hibernation (David Woodhouse).

   - Update outdated operating performance points (OPP) documentation
     (Tang Yizhou).

   - Reduce log severity for informative message regarding frequency
     transition failures in devfreq (Tzung-Bi Shih).

   - Add DRAM frequency controller devfreq driver for Allwinner sunXi
     SoCs (Samuel Holland).

   - Add missing COMMON_CLK dependency to sun8i devfreq driver (Arnd
     Bergmann).

   - Add support for new layout of Psys PowerLimit Register on SPR to
     the Intel RAPL power capping driver (Zhang Rui).

   - Fix typo in a comment in idle_inject.c (Jason Wang).

   - Remove unused function definition from the DTPM (Dynamit Thermal
     Power Management) power capping framework (Daniel Lezcano).

   - Add AEST to the list of known ACPI table signatures (Shuuichirou
     Ishii).
