-
-From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
-
-[ Upstream commit d518691cbd3be3dae218e05cca3f3fc9b2f1aa77 ]
-
-The driver uses __napi_schedule_irqoff() which is fine as long as it is
-invoked with disabled interrupts by everybody. Since the commit
-mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq
-context. This may lead to list corruption if another driver uses
-__napi_schedule_irqoff() in IRQ context.
-
-Use __napi_schedule() which safe to use from IRQ and softirq context.

-
-From: Taehee Yoo <ap420073@gmail.com>
-
-[ Upstream commit 4faab8c446def7667adf1f722456c2f4c304069c ]
-
-In the current hsr code, only 0 and 1 protocol versions are valid.
-But current hsr code doesn't check the version, which is received by
-userspace.
-
-Test commands:
- ip link add dummy0 type dummy
- ip link add dummy1 type dummy
- ip link add hsr0 type hsr slave1 dummy0 slave2 dummy1 version 4
-
-In the test commands, version 4 is invalid.
-So, the command should be failed.
-
-After this patch, following error will occur.
-"Error: hsr: Only versions 0..1 are supported."

-Subject: l2tp: Allow management of tunnels and session in user namespace
-
-From: "Michael Weiß" <michael.weiss@aisec.fraunhofer.de>
-
-[ Upstream commit 2abe05234f2e892728c388169631e4b99f354c86 ]
-
-Creation and management of L2TPv3 tunnels and session through netlink
-requires CAP_NET_ADMIN. However, a process with CAP_NET_ADMIN in a
-non-initial user namespace gets an EPERM due to the use of the
-genetlink GENL_ADMIN_PERM flag. Thus, management of L2TP VPNs inside
-an unprivileged container won't work.
-
-We replaced the GENL_ADMIN_PERM by the GENL_UNS_ADMIN_PERM flag
-similar to other network modules which also had this problem, e.g.,
-openvswitch (commit 4a92602aa1cd "openvswitch: allow management from
-inside user namespaces") and nl80211 (commit 5617c6cd6f844 "nl80211:
-Allow privileged operations from user namespaces").
-
-I tested this in the container runtime trustm3 (trustm3.github.io)
-and was able to create l2tp tunnels and sessions in unpriviliged
-(user namespaced) containers using a private network namespace.
-For other runtimes such as docker or lxc this should work, too.

-Subject: net: ipv6: do not consider routes via gateways for anycast address check
-
-From: Tim Stallard <code@timstallard.me.uk>
-
-[ Upstream commit 03e2a984b6165621f287fadf5f4b5cd8b58dcaba ]
-
-The behaviour for what is considered an anycast address changed in
-commit 45e4fd26683c ("ipv6: Only create RTF_CACHE routes after
-encountering pmtu exception"). This now considers the first
-address in a subnet where there is a route via a gateway
-to be an anycast address.
-
-This breaks path MTU discovery and traceroutes when a host in a
-remote network uses the address at the start of a prefix
-(eg 2600:: advertised as 2600::/48 in the DFZ) as ICMP errors
-will not be sent to anycast addresses.
-
-This patch excludes any routes with a gateway, or via point to
-point links, like the behaviour previously from
-rt6_is_gw_or_nonexthop in net/ipv6/route.c.
-
-This can be tested with:
-ip link add v1 type veth peer name v2
-ip netns add test
-ip netns exec test ip link set lo up
-ip link set v2 netns test
-ip link set v1 up
-ip netns exec test ip link set v2 up
-ip addr add 2001:db8::1/64 dev v1 nodad
-ip addr add 2001:db8:100:: dev lo nodad
-ip netns exec test ip addr add 2001:db8::2/64 dev v2 nodad
-ip netns exec test ip route add unreachable 2001:db8:1::1
-ip netns exec test ip route add 2001:db8:100::/64 via 2001:db8::1
-ip netns exec test sysctl net.ipv6.conf.all.forwarding=1
-ip route add 2001:db8:1::1 via 2001:db8::2
-ping -I 2001:db8::1 2001:db8:1::1 -c1
-ping -I 2001:db8:100:: 2001:db8:1::1 -c1
-ip addr delete 2001:db8:100:: dev lo
-ip netns delete test
-
-Currently the first ping will get back a destination unreachable ICMP
-error, but the second will never get a response, with "icmp6_send:
-acast source" logged. After this patch, both get destination
-unreachable ICMP replies.

-Subject: net: macsec: fix using wrong structure in macsec_changelink()
-
-From: Taehee Yoo <ap420073@gmail.com>
-
-[ Upstream commit 022e9d6090599c0593c78e87dc9ba98a290e6bc4 ]
-
-In the macsec_changelink(), "struct macsec_tx_sa tx_sc" is used to
-store "macsec_secy.tx_sc".
-But, the struct type of tx_sc is macsec_tx_sc, not macsec_tx_sa.
-So, the macsec_tx_sc should be used instead.
-
-Test commands:
- ip link add dummy0 type dummy
- ip link add macsec0 link dummy0 type macsec
- ip link set macsec0 type macsec encrypt off
-
-Splat looks like:

-Current value of nest_level, assigned from net_device lower_level value,
-does not reflect the actual number of vlan headers, needed to pop.
-For ex., if we have untagged ingress traffic sended over vlan devices,

-Subject: net: icmp6: do not select saddr from iif when route has prefsrc set
-
-From: Tim Stallard <code@timstallard.me.uk>
-
-[ Upstream commit b93cfb9cd3af3adc9ba4854f178d5300f7544d3e ]
-
-Since commit fac6fce9bdb5 ("net: icmp6: provide input address for
-traceroute6") ICMPv6 errors have source addresses from the ingress
-interface. However, this overrides when source address selection is
-influenced by setting preferred source addresses on routes.
-
-This can result in ICMP errors being lost to upstream BCP38 filters
-when the wrong source addresses are used, breaking path MTU discovery
-and traceroute.
-
-This patch sets the modified source address selection to only take place
-when the route used has no prefsrc set.
-
-It can be tested with:
-
-ip link add v1 type veth peer name v2
-ip netns add test
-ip netns exec test ip link set lo up
-ip link set v2 netns test
-ip link set v1 up

-be transmitted as untagged on a particular egress port. That is the
-"native VLAN on trunk port" use case.
-
-The configuration for this native VLAN is driven in 2 ways:
- - Set the egress port rewriter to strip the VLAN tag for the native
- VID (as it is egress-untagged, after all).
- - Configure the ingress port to drop untagged and priority-tagged
- traffic, if there is no native VLAN. The intention of this setting is
- that a trunk port with no native VLAN should not accept untagged
- traffic.
-
-Since both of the above configurations for the native VLAN should only
-be done if VLAN awareness is requested, they are actually done from the
-ocelot_port_vlan_filtering function, after the basic procedure of
-toggling the VLAN awareness flag of the port.
-
-But there's a problem with that simplistic approach: we are trying to
-juggle with 2 independent variables from a single function:
- - Native VLAN of the port - its value is held in port->vid.
- - VLAN awareness state of the port - currently there are some issues
- here, more on that later*.
-The actual problem can be seen when enslaving the switch ports to a VLAN
-filtering bridge:
- 0. The driver configures a pvid of zero for each port, when in
- standalone mode. While the bridge configures a default_pvid of 1 for
- each port that gets added as a slave to it.
- 1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true.
- The VLAN-filtering-dependent portion of the native VLAN
- configuration is done, considering that the native VLAN is 0.
- 2. The bridge calls ocelot_vlan_add with vid=1, pvid=true,
- untagged=true. The native VLAN changes to 1 (change which gets
- propagated to hardware).
- 3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the
- VLAN-filtering-dependent portion of the native VLAN configuration,
- for the new native VLAN of 1. One can notice that after toggling "ip
- link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0
- type bridge vlan_filtering 1", the new native VLAN finally makes it
- through and untagged traffic finally starts flowing again. But
- obviously that shouldn't be needed.
-
-So it is clear that 2 independent variables need to both re-trigger the
-native VLAN configuration. So we introduce the second variable as
-ocelot_port->vlan_aware.
-
-*Actually both the DSA Felix driver and the Ocelot driver already had
-each its own variable:
- - Ocelot: ocelot_port_private->vlan_aware
- - Felix: dsa_port->vlan_filtering
-but the common Ocelot library needs to work with a single, common,
-variable, so there is some refactoring done to move the vlan_aware
-property from the private structure into the common ocelot_port
-structure.

-From: Florian Fainelli <f.fainelli@gmail.com>
-
-[ Upstream commit 806fd188ce2a4f8b587e83e73c478e6484fbfa55 ]
-
-After commit bfcb813203e619a8960a819bf533ad2a108d8105 ("net: dsa:
-configure the MTU for switch ports") my Lamobo R1 platform which uses
-an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail
-by rejecting a MTU of 1536. The reason for that is that the DMA
-capabilities are not readable on this version of the IP, and there
-is also no 'tx-fifo-depth' property being provided in Device Tree. The
-property is documented as optional, and is not provided.
-
-Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so
-provide these values through platform data as an immediate fix until
-various Device Tree sources get updated accordingly.

-Subject: net: phy: marvell: Fix pause frame negotiation
-
-From: Clemens Gruber <clemens.gruber@pqgruber.com>
-
-[ Upstream commit 3b72f84f8fb65e83e85e9be58eabcf95a40b8f46 ]
-
-The negotiation of flow control / pause frame modes was broken since
-commit fcf1f59afc67 ("net: phy: marvell: rearrange to use
-genphy_read_lpa()") moved the setting of phydev->duplex below the
-phy_resolve_aneg_pause call. Due to a check of DUPLEX_FULL in that
-function, phydev->pause was no longer set.
-
-Fix it by moving the parsing of the status variable before the blocks
-dealing with the pause frames.
-
-As the Marvell 88E1510 datasheet does not specify the timing between the
-link status and the "Speed and Duplex Resolved" bit, we have to force
-the link down as long as the resolved bit is not set, to avoid reporting
-link up before we even have valid Speed/Duplex.
-
-Tested with a Marvell 88E1510 (RGMII to Copper/1000Base-T)

-Subject: ovl: fix value of i_ino for lower hardlink corner case
-
-From: Amir Goldstein <amir73il@gmail.com>
-
-commit 300b124fcf6ad2cd99a7b721e0f096785e0a3134 upstream.
-
-Commit 6dde1e42f497 ("ovl: make i_ino consistent with st_ino in more
-cases"), relaxed the condition nfs_export=on in order to set the value of
-i_ino to xino map of real ino.
-
-Specifically, it also relaxed the pre-condition that index=on for
-consistent i_ino. This opened the corner case of lower hardlink in
-ovl_get_inode(), which calls ovl_fill_inode() with ino=0 and then
-ovl_init_inode() is called to set i_ino to lower real ino without the xino
-mapping.
-
-Pass the correct values of ino;fsid in this case to ovl_fill_inode(), so it
-can initialize i_ino correctly.

-
-From: Can Guo <cang@codeaurora.org>
-
-commit c63d6099a7959ecc919b2549dc6b71f53521f819 upstream.
-
-The async version of ufshcd_hold(async == true), which is only called in
-queuecommand path as for now, is expected to work in atomic context, thus
-it should not sleep or schedule out. When it runs into the condition that
-clocks are ON but link is still in hibern8 state, it should bail out
-without flushing the clock ungate work.

-Subject: platform/chrome: cros_ec_rpmsg: Fix race with host event
-
-From: Pi-Hsun Shih <pihsun@chromium.org>
-
-commit f775ac78fcfc6bdc96bdda07029d11f2a5e84869 upstream.
-
-Host event can be sent by remoteproc by any time, and
-cros_ec_rpmsg_callback would be called after cros_ec_rpmsg_create_ept.
-But the cros_ec_device is initialized after that, which cause host event
-handler to use cros_ec_device that are not initialized properly yet.
-
-Fix this by don't schedule host event handler before cros_ec_register
-returns. Instead, remember that we have a pending host event, and
-schedule host event handler after cros_ec_register.
-
-Fixes: 71cddb7097e2 ("platform/chrome: cros_ec_rpmsg: Fix race with host command when probe failed.")

-Subject: acpi/nfit: improve bounds checking for 'func'
-
-From: Dan Carpenter <dan.carpenter@oracle.com>
-
-commit 01091c496f920e634ea84b689f480c39016752a8 upstream.
-
-The 'func' variable can come from the user in the __nd_ioctl(). If it's
-too high then the (1 << func) shift in acpi_nfit_clear_to_send() is
-undefined. In acpi_nfit_ctl() we pass 'func' to test_bit(func, &dsm_mask)
-which could result in an out of bounds access.
-
-To fix these issues, I introduced the NVDIMM_CMD_MAX (31) define and
-updated nfit_dsm_revid() to use that define as well instead of magic
-numbers.

-Subject: perf report: Fix no branch type statistics report issue
-
-From: Jin Yao <yao.jin@linux.intel.com>
-
-commit c3b10649a80e9da2892c1fd3038c53abd57588f6 upstream.
-
-Previously we could get the report of branch type statistics.
-
-For example:
-
- # perf record -j any,save_type ...
- # t perf report --stdio
-
- #
- # Branch Statistics:
- #
- COND_FWD: 40.6%
- COND_BWD: 4.1%
- CROSS_4K: 24.7%
- CROSS_2M: 12.3%
- COND: 44.7%
- UNCOND: 0.0%
- IND: 6.1%
- CALL: 24.5%
- RET: 24.7%
-
-But now for the recent perf, it can't report the branch type statistics.
-
-It's a regression issue caused by commit 40c39e304641 ("perf report: Fix
-a no annotate browser displayed issue"), which only counts the branch
-type statistics for browser mode.
-
-This patch moves the branch_type_count() outside of ui__has_annotation()
-checking, then branch type statistics can work for stdio mode.
-
-Fixes: 40c39e304641 ("perf report: Fix a no annotate browser displayed issue")

-Subject: pwm: pca9685: Fix PWM/GPIO inter-operation
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Sven Van Asbroeck <TheSven73@gmail.com>
-
-commit 9cc5f232a4b6a0ef6e9b57876d61b88f61bdd7c2 upstream.
-
-This driver allows pwms to be requested as gpios via gpiolib. Obviously,
-it should not be allowed to request a GPIO when its corresponding PWM is
-already requested (and vice versa). So it requires some exclusion code.
-
-Given that the PWMm and GPIO cores are not synchronized with respect to
-each other, this exclusion code will also require proper
-synchronization.
-
-Such a mechanism was in place, but was inadvertently removed by Uwe's
-clean-up in commit e926b12c611c ("pwm: Clear chip_data in pwm_put()").
-
-Upon revisiting the synchronization mechanism, we found that
-theoretically, it could allow two threads to successfully request
-conflicting PWMs/GPIOs.
-
-Replace with a bitmap which tracks PWMs in-use, plus a mutex. As long as
-PWM and GPIO's respective request/free functions modify the in-use
-bitmap while holding the mutex, proper synchronization will be
-guaranteed.

-commit 41c55ea6c2a7ca4c663eeec05bdf54f4e2419699 upstream.
-
-A testing message was brought by 13d0f7b814d9 ("net/bpfilter: fix dprintf
-usage for /dev/kmsg") but should've been deleted before patch submission.
-Although it doesn't cause any harm to the code or functionality itself, it's
-totally unpleasant to have it displayed on every loop iteration with no real
-use case. Thus remove it unconditionally.

-
-ext4_fill_super doublechecks the number of groups before mounting; if
-that check fails, the resulting error message prints the group count
-from the ext4_sb_info sbi, which hasn't been set yet. Print the freshly
-computed group count instead (which at that point has just been computed

-Subject: HID: lg-g15: Do not fail the probe when we fail to disable F# emulation
-
-From: Hans de Goede <hdegoede@redhat.com>
-
-commit b8a75eaddae9410767c7d95a1c5f3a547aae7b81 upstream.
-
-By default the G1-G12 keys on the Logitech gaming keyboards send
-F1 - F12 when in "generic HID" mode.
-
-The first thing the hid-lg-g15 driver does is disable this behavior.
-
-We have received a bugreport that this does not work when the keyboard
-is connected through an Aten KVM switch. Using a gaming keyboard with
-a KVM is a bit weird setup, but still we can try to fail a bit more
-gracefully here.
-
-On the G510 keyboards the same USB-interface which is used for the gaming
-keys is also used for the media-keys. Before this commit we would call
-hid_hw_stop() on failure to disable the F# emulation and then exit the
-probe method with an error code.
-
-This not only causes us to not handle the gaming-keys, but this also
-breaks the media keys which is a regression compared to the situation
-when these keyboards where handled by the generic hidinput driver.
-
-This commit changes the error handling to clear the hiddev drvdata
-(to disable our .raw_event handler) and then returning from the probe
-method with success.
-
-The net result of this is that, when connected through a KVM, things
-work as well as they did before the hid-lg-g15 driver was introduced.
-
-Fixes: ad4203f5a243 ("HID: lg-g15: Add support for the G510 keyboards' gaming keys")

-Subject: ALSA: hda: Allow setting preallocation again for x86
-
-From: Takashi Iwai <tiwai@suse.de>
-
-commit f8e4ae10de43fbb7ce85f79e04eca2988b6b2c40 upstream.
-
-The commit c31427d0d21e ("ALSA: hda: No preallocation on x86
-platforms") changed CONFIG_SND_HDA_PREALLOC_SIZE setup and its default
-to zero for x86, as the preallocation should work almost all cases.
-However, this expectation was too naive; some applications try to
-allocate as the max buffer size as possible, and it leads to the
-memory exhaustion. More badly, the commit changed the kconfig no
-longer adjustable for x86, so you can't fix it statically (although it

-
-From: Adam Barber <barberadam995@gmail.com>
-
-commit 4963d66b8a26c489958063abb6900ea6ed8e4836 upstream.
-
-On Asus FX505DT with Realtek ALC233, the headset mic is connected
-to pin 0x19, with default 0x411111f0.
-
-Enable headset mic by reconfiguring the pin to an external mic
-associated with the headphone on 0x21. Mic jack detection was also
-found to be working.

-From: Takashi Iwai <tiwai@suse.de>
-
-commit 48cc42973509afac24e83d6edc23901d102872d1 upstream.
-
-The ignore_ctl_error option should filter the error at kctl accesses,
-but there was an overlook: mixer_ctl_connector_get() returns an error
-from the request.
-
-This patch covers the forgotten code path and apply filter_error()
-properly. The locking error is still returned since this is a fatal
-error that has to be reported even with ignore_ctl_error option.

-
-From: Takashi Iwai <tiwai@suse.de>
-
-commit 3507245b82b4362dc9721cbc328644905a3efa22 upstream.
-
-The mapping table may contain also ignore_ctl_error flag for devices
-that are known to behave wild. Since this flag always writes the
-card's own ignore_ctl_error flag, it overrides the value already set
-by the module option, so it doesn't follow user's expectation.
-Let's fix the code not to clear the flag that has been set by user.

-
-From: Mark Rutland <mark.rutland@arm.com>
-
-commit 9cc3d0c6915aee5140f8335d41bbc3ff1b79aa4e upstream.
-
-The aarch32_vdso_pages[] array never has entries allocated in the C_VVAR
-or C_VDSO slots, and as the array is zero initialized these contain
-NULL.
-
-However in __aarch32_alloc_vdso_pages() when
-aarch32_alloc_kuser_vdso_page() fails we attempt to free the page whose
-struct page is at NULL, which is obviously nonsensical.
-
-This patch removes the erroneous page freeing.

-Subject: tracing: Fix the race between registering 'snapshot' event trigger and triggering 'snapshot' operation
-
-From: Xiao Yang <yangx.jy@cn.fujitsu.com>
-
-commit 0bbe7f719985efd9adb3454679ecef0984cb6800 upstream.
-
-Traced event can trigger 'snapshot' operation(i.e. calls snapshot_trigger()
-or snapshot_count_trigger()) when register_snapshot_trigger() has completed
-registration but doesn't allocate buffer for 'snapshot' event trigger. In
-the rare case, 'snapshot' operation always detects the lack of allocated
-buffer so make register_snapshot_trigger() allocate buffer first.
-
-trigger-snapshot.tc in kselftest reproduces the issue on slow vm:

-Subject: btrfs: check commit root generation in should_ignore_root
-
-From: Josef Bacik <josef@toxicpanda.com>
-
-commit 4d4225fc228e46948486d8b8207955f0c031b92e upstream.
-
-Previously we would set the reloc root's last snapshot to transid - 1.
-However there was a problem with doing this, and we changed it to
-setting the last snapshot to the generation of the commit node of the fs
-root.
-
-This however broke should_ignore_root(). The assumption is that if we
-are in a generation newer than when the reloc root was created, then we
-would find the reloc root through normal backref lookups, and thus can
-ignore any fs roots we find with an old enough reloc root.
-
-Now that the last snapshot could be considerably further in the past
-than before, we'd end up incorrectly ignoring an fs root. Thus we'd
-find no nodes for the bytenr we were searching for, and we'd fail to
-relocate anything. We'd loop through the relocate code again and see
-that there were still used space in that block group, attempt to
-relocate those bytenr's again, fail in the same way, and just loop like
-this forever. This is tricky in that we have to not modify the fs root
-at all during this time, so we need to have a block group that has data
-in this fs root that is not shared by any other root, which is why this
-has been difficult to reproduce.
-

-Subject: mac80211: fix race in ieee80211_register_hw()
-
-From: Sumit Garg <sumit.garg@linaro.org>
-
-commit 52e04b4ce5d03775b6a78f3ed1097480faacc9fd upstream.
-
-A race condition leading to a kernel crash is observed during invocation
-of ieee80211_register_hw() on a dragonboard410c device having wcn36xx
-driver built as a loadable module along with a wifi manager in user-space
-waiting for a wifi device (wlanX) to be active.
-
-Sequence diagram for a particular kernel crash scenario:
-
- user-space ieee80211_register_hw() ieee80211_tasklet_handler()
- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- | | |
- |<---phy0----wiphy_register() |
- |-----iwd if_add---->| |
- | |<---IRQ----(RX packet)
- | Kernel crash |
- | due to unallocated |
- | workqueue. |
- | | |
- | alloc_ordered_workqueue() |
- | | |
- | Misc wiphy init. |
- | | |
- | ieee80211_if_add() |
- | | |
-
-As evident from above sequence diagram, this race condition isn't specific
-to a particular wifi driver but rather the initialization sequence in
-ieee80211_register_hw() needs to be fixed. So re-order the initialization
-sequence and the updated sequence diagram would look like:
-
- user-space ieee80211_register_hw() ieee80211_tasklet_handler()
- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- | | |
- | alloc_ordered_workqueue() |
- | | |
- | Misc wiphy init. |
- | | |
- |<---phy0----wiphy_register() |
- |-----iwd if_add---->| |
- | |<---IRQ----(RX packet)

-Subject: net/mlx5e: Rename hw_modify to preactivate
-
-From: Maxim Mikityanskiy <maximmi@mellanox.com>
-
-[ Upstream commit dca147b3dce5abb5284ff747211960fd2db5ec2e ]
-
-mlx5e_safe_switch_channels accepts a callback to be called before
-activating new channels. It is intended to configure some hardware
-parameters in cases where channels are recreated because some
-configuration has changed.
-
-Recently, this callback has started being used to update the driver's
-internal MLX5E_STATE_XDP_OPEN flag, and the following patches also
-intend to use this callback for software preparations. This patch
-renames the hw_modify callback to preactivate, so that the name fits
-better.

-Subject: net/mlx5e: Use preactivate hook to set the indirection table
-
-From: Maxim Mikityanskiy <maximmi@mellanox.com>
-
-[ Upstream commit fe867cac9e1967c553e4ac2aece5fc8675258010 ]
-
-mlx5e_ethtool_set_channels updates the indirection table before
-switching to the new channels. If the switch fails, the indirection
-table is new, but the channels are old, which is wrong. Fix it by using
-the preactivate hook of mlx5e_safe_switch_channels to update the
-indirection table at the stage when nothing can fail anymore.
-
-As the code that updates the indirection table is now encapsulated into
-a new function, use that function in the attach flow when the driver has
-to reduce the number of channels, and prepare the code for the next
-commit.
-
-Fixes: 85082dba0a ("net/mlx5e: Correctly handle RSS indirection table when changing number of channels")

-Subject: i2c: designware: platdrv: Remove DPM_FLAG_SMART_SUSPEND flag on BYT and CHT
-
-From: Hans de Goede <hdegoede@redhat.com>
-
-commit d79294d0de12ddd1420110813626d691f440b86f upstream.
-
-We already set DPM_FLAG_SMART_PREPARE, so we completely skip all
-callbacks (other then prepare) where possible, quoting from
-dw_i2c_plat_prepare():
-
- /*
- * If the ACPI companion device object is present for this device, it
- * may be accessed during suspend and resume of other devices via I2C
- * operation regions, so tell the PM core and middle layers to avoid
- * skipping system suspend/resume callbacks for it in that case.
- */
- return !has_acpi_companion(dev);
-
-Also setting the DPM_FLAG_SMART_SUSPEND will cause acpi_subsys_suspend()
-to leave the controller runtime-suspended even if dw_i2c_plat_prepare()
-returned 0.
-
-Leaving the controller runtime-suspended normally, when the I2C controller
-is suspended during the suspend_late phase, is not an issue because
-the pm_runtime_get_sync() done by i2c_dw_xfer() will (runtime-)resume it.
-
-But for dw I2C controllers on Bay- and Cherry-Trail devices acpi_lpss.c
-leaves the controller alive until the suspend_noirq phase, because it may
-be used by the _PS3 ACPI methods of PCI devices and PCI devices are left
-powered on until the suspend_noirq phase.
-
-Between the suspend_late and resume_early phases runtime-pm is disabled.
-So for any ACPI I2C OPRegion accesses done after the suspend_late phase,
-the pm_runtime_get_sync() done by i2c_dw_xfer() is a no-op and the
-controller is left runtime-suspended.
-
-i2c_dw_xfer() has a check to catch this condition (rather then waiting
-for the I2C transfer to timeout because the controller is suspended).
-acpi_subsys_suspend() leaving the controller runtime-suspended in
-combination with an ACPI I2C OPRegion access done after the suspend_late
-phase triggers this check, leading to the following error being logged
-on a Bay Trail based Lenovo Thinkpad 8 tablet:
-
-[ 93.275882] i2c_designware 80860F41:00: Transfer while suspended

-
-So since on BYT and CHT platforms we want ACPI I2c OPRegion accesses
-to work until the suspend_noirq phase, we need the controller to be
-runtime-resumed during the suspend phase if it is runtime-suspended
-suspended at that time. This means that we must not set the
-DPM_FLAG_SMART_SUSPEND on these platforms.
-
-On BYT and CHT we already have a special ACCESS_NO_IRQ_SUSPEND flag
-to make sure the controller stays functional until the suspend_noirq
-phase. This commit makes the driver not set the DPM_FLAG_SMART_SUSPEND
-flag when that flag is set.

-Subject: drm/i915/perf: Do not clear pollin for small user read buffers
-
-From: Ashutosh Dixit <ashutosh.dixit@intel.com>
-
-commit bcad588dea538a4fc173d16a90a005536ec8dbf2 upstream.
-
-It is wrong to block the user thread in the next poll when OA data is
-already available which could not fit in the user buffer provided in
-the previous read. In several cases the exact user buffer size is not
-known. Blocking user space in poll can lead to data loss when the
-buffer size used is smaller than the available data.
-
-This change fixes this issue and allows user space to read all OA data
-even when using a buffer size smaller than the available data using
-multiple non-blocking reads rather than staying blocked in poll till
-the next timer interrupt.
-
-v2: Fix ret value for blocking reads (Umesh)
-v3: Mistake during patch send (Ashutosh)
-v4: Remove -EAGAIN from comment (Umesh)
-v5: Improve condition for clearing pollin and return (Lionel)
-v6: Improve blocking read loop and other cleanups (Lionel)
-v7: Added Cc stable

-- *
-- * For example ret will be -ENOSPC whenever there is more buffered data than
-- * can be copied to userspace, but that's only interesting if we weren't able
-- * to copy some data because it implies the userspace buffer is too small to
-- * receive a single record (and we never split records).
-- *
-- * Another case with ret == -EFAULT is more of a grey area since it would seem
-- * like bad form for userspace to ask us to overrun its buffer, but the user
-- * knows best:
