kernel: remove support for kernel 4.19
We use 5.4 on all targets by default, and 4.19 has never been released in a stable version. There is no reason to keep it. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

-Subject: [PATCH] netfilter: conntrack: cache route for forwarded connections
-
-... to avoid per-packet FIB lookup if possible.
-
-The cached dst is re-used provided the input interface
-is the same as that of the previous packet in the same direction.
-
-If not, the cached dst is invalidated.
-
-For ipv6 we also need to store sernum, else dst_check doesn't work,
-pointed out by Eric Dumazet.
-
-This should speed up forwarding when conntrack is already in use
-anyway, especially when using reverse path filtering -- active RPF
-enforces two FIB lookups for each packet.
-
-Before the routing cache removal this didn't matter since RPF was performed
-only when route cache didn't yield a result; but without route cache it
-comes at higher price.
-
-Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
-avoid holding on to dsts of 'frozen' conntracks.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When allocating a new partition mtd subsystem runs internal tests in the
-allocate_partition(). They may result in modifying specified flags (e.g.
-dropping some /features/ like write access).
-
-Those constraints don't have to be necessary true for subpartitions. It
-may happen parent partition isn't block aligned (effectively disabling
-write access) while subpartition may fit blocks nicely. In such case all
-checks should be run again (starting with original flags value).

-Subject: [PATCH 1/1] Allow class-e address assignment in ifconfig and early
- boot
-
-While the linux kernel became mostly "class-e clean" a decade ago,
-and most distributions long ago switched to the iproute2 suite
-of utilities, which allow class-e (240.0.0.0/4) address assignment,
-distributions relying on busybox, toybox and other forms of
-ifconfig cannot assign class-e addresses without this kernel patch.
-
-With this patch, also, a boot command line on these addresses is feasible:
-(ip=248.0.1.2::248.0.1.1:255.255.255.0).
-
-While CIDR has been obsolete for 2 decades, and a survey of all the
-userspace open source code in the world shows most IN_whatever macros
-are also obsolete... rather than obsolete CIDR from this ioctl entirely,
-this patch merely enables class-e assignment, sanely.
-
-H/T to Vince Fuller and his original patch here:

-Subject: [PATCH 2/2] arm: cns3xxx: use actual size reads for PCIe
-
-commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
-reimplemented cns3xxx_pci_read_config() using pci_generic_config_read32(),
-which preserved the property of only doing 32-bit reads.
-
-It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(),
-so it changed writes from always being 32 bits to being the actual size,
-which works just fine.
-
-Due to:
-- The documentation does not mention that only 32 bit access is allowed.
-- Writes are already executed using the actual size
-- Extensive testing shows that 8b, 16b and 32b reads work as intended
-
-It makes perfectly sense to also swap 32 bit reading in favor of actual size.
-

-Subject: [PATCH] arm64/sve: Disentangle <uapi/asm/ptrace.h> from
- <uapi/asm/sigcontext.h>
-
-Currently, <uapi/asm/sigcontext.h> provides common definitions for
-describing SVE context structures that are also used by the ptrace
-definitions in <uapi/asm/ptrace.h>.
-
-For this reason, a #include of <asm/sigcontext.h> was added in
-ptrace.h, but it this turns out that this can interact badly with
-userspace code that tries to include ptrace.h on top of the libc
-headers (which may provide their own shadow definitions for
-sigcontext.h).
-
-To make the headers easier for userspace to consume, this patch
-bounces the common definitions into an __SVE_* namespace and moves
-them to a backend header <uapi/asm/sve_context.h> that can be
-included by the other headers as appropriate. This should allow
-ptrace.h to be used alongside libc's sigcontext.h (if any) without
-ill effects.
-
-This should make the situation unambiguous: <asm/sigcontext.h> is
-the header to include for the sigframe-specific definitions, while
-<asm/ptrace.h> is the header to include for ptrace-specific
-definitions.
-
-To avoid conflicting with existing usage, <asm/sigcontext.h>
-remains the canonical way to get the common definitions for
-SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
-kernel: relying on these being defined as a side effect of
-including just <asm/ptrace.h> was never intended to be safe.

-Subject: [PATCH] netfilter: nf_flow_table: fix offloaded connection timeout
- corner case
-
-The full teardown of offloaded flows is deferred to a gc work item,
-however processing of packets by netfilter needs to happen immediately
-after a teardown is requested, because the conntrack state needs to be
-fixed up.
-
-Since the IPS_OFFLOAD_BIT is still kept until the teardown is complete,
-the netfilter conntrack gc can accidentally bump the timeout of a
-connection where offload was just stopped, causing a conntrack entry
-leak.
-
-Fix this by moving the conntrack timeout bumping from conntrack core to
-the nf_flow_offload and add a check to prevent bogus timeout bumps.

-Subject: [PATCH] net: sched: Backport Introduce act_ctinfo action
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-ctinfo is a new tc filter action module. It is designed to restore
-information contained in firewall conntrack marks to other packet fields
-and is typically used on packet ingress paths. At present it has two
-independent sub-functions or operating modes, DSCP restoration mode &
-skb mark restoration mode.
-
-The DSCP restore mode:
-
-This mode copies DSCP values that have been placed in the firewall
-conntrack mark back into the IPv4/v6 diffserv fields of relevant
-packets.
-
-The DSCP restoration is intended for use and has been found useful for
-restoring ingress classifications based on egress classifications across
-links that bleach or otherwise change DSCP, typically home ISP Internet
-links. Restoring DSCP on ingress on the WAN link allows qdiscs such as
-but by no means limited to CAKE to shape inbound packets according to
-policies that are easier to set & mark on egress.
-
-Ingress classification is traditionally a challenging task since
-iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
-lookups, hence are unable to see internal IPv4 addresses as used on the
-typical home masquerading gateway. Thus marking the connection in some
-manner on egress for later restoration of classification on ingress is
-easier to implement.
-
-Parameters related to DSCP restore mode:
-
-dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
-conntrack mark field contain the DSCP value to be restored.
-
-statemask - a 32 bit mask of (usually) 1 bit length, outside the area
-specified by dscpmask. This represents a conditional operation flag
-whereby the DSCP is only restored if the flag is set. This is useful to
-implement a 'one shot' iptables based classification where the
-'complicated' iptables rules are only run once to classify the
-connection on initial (egress) packet and subsequent packets are all
-marked/restored with the same DSCP. A mask of zero disables the
-conditional behaviour ie. the conntrack mark DSCP bits are always
-restored to the ip diffserv field (assuming the conntrack entry is found
-& the skb is an ipv4/ipv6 type)
-
-e.g. dscpmask 0xfc000000 statemask 0x01000000
-
-|----0xFC----conntrack mark----000000---|
-| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
-| DSCP | unused | flag |unused |
-|-----------------------0x01---000000---|
- | |
- | |
- ---| Conditional flag
- v only restore if set
-|-ip diffserv-|
-| 6 bits |
-|-------------|
-
-The skb mark restore mode (cpmark):
-
-This mode copies the firewall conntrack mark to the skb's mark field.
-It is completely the functional equivalent of the existing act_connmark
-action with the additional feature of being able to apply a mask to the
-restored value.
-
-Parameters related to skb mark restore mode:
-
-mask - a 32 bit mask applied to the firewall conntrack mark to mask out
-bits unwanted for restoration. This can be useful where the conntrack
-mark is being used for different purposes by different applications. If
-not specified and by default the whole mark field is copied (i.e.
-default mask of 0xffffffff)
-
-e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
-aforementioned DSCP restore mode.
-
-|----0x00----conntrack mark----ffffff---|
-| Bits 31-24 | |
-| DSCP & flag| some value here |
-|---------------------------------------|
- |
- |
- v
-|------------skb mark-------------------|
-| | |
-| zeroed | |
-|---------------------------------------|
-
-Overall parameters:
-
-zone - conntrack zone
-
-control - action related control (reclassify | pipe | drop | continue |
-ok | goto chain <CHAIN_INDEX>)

-Subject: [PATCH] sch_cake: Make the dual modes fairer
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-CAKE host fairness does not work well with TCP flows in dual-srchost and
-dual-dsthost setup. The reason is that ACKs generated by TCP flows are
-classified as sparse flows, and affect flow isolation from other hosts. Fix
-this by calculating host_load based only on the bulk flows a host
-generates. In a hash collision the host_bulk_flow_count values must be
-decremented on the old hosts and incremented on the new ones *if* the queue
-is in the bulk set.

-Subject: [PATCH] sch_cake: Permit use of connmarks as tin classifiers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add flag 'FWMARK' to enable use of firewall connmarks as tin selector.
-The connmark (skbuff->mark) needs to be in the range 1->tin_cnt ie.
-for diffserv3 the mark needs to be 1->3.
-
-Background
-
-Typically CAKE uses DSCP as the basis for tin selection. DSCP values
-are relatively easily changed as part of the egress path, usually with
-iptables & the mangle table, ingress is more challenging. CAKE is often
-used on the WAN interface of a residential gateway where passthrough of
-DSCP from the ISP is either missing or set to unhelpful values thus use
-of ingress DSCP values for tin selection isn't helpful in that
-environment.
-
-An approach to solving the ingress tin selection problem is to use
-CAKE's understanding of tc filters. Naive tc filters could match on
-source/destination port numbers and force tin selection that way, but
-multiple filters don't scale particularly well as each filter must be
-traversed whether it matches or not. e.g. a simple example to map 3
-firewall marks to tins:
-
-MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
-tc filter add dev $DEV parent $MAJOR protocol all handle 0x01 fw action skbedit priority ${MAJOR}1
-tc filter add dev $DEV parent $MAJOR protocol all handle 0x02 fw action skbedit priority ${MAJOR}2
-tc filter add dev $DEV parent $MAJOR protocol all handle 0x03 fw action skbedit priority ${MAJOR}3
-
-Another option is to use eBPF cls_act with tc filters e.g.
-
-MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
-tc filter add dev $DEV parent $MAJOR bpf da obj my-bpf-fwmark-to-class.o
-
-This has the disadvantages of a) needing someone to write & maintain
-the bpf program, b) a bpf toolchain to compile it and c) needing to
-hardcode the major number in the bpf program so it matches the cake
-instance (or forcing the cake instance to a particular major number)
-since the major number cannot be passed to the bpf program via tc
-command line.
-
-As already hinted at by the previous examples, it would be helpful
-to associate tins with something that survives the Internet path and
-ideally allows tin selection on both egress and ingress. Netfilter's
-conntrack permits setting an identifying mark on a connection which
-can also be restored to an ingress packet with tc action connmark e.g.
-
-tc filter add dev eth0 parent ffff: protocol all prio 10 u32 \
- match u32 0 0 flowid 1:1 action connmark action mirred egress redirect dev ifb1
-
-Since tc's connmark action has restored any connmark into skb->mark,
-any of the previous solutions are based upon it and in one form or
-another copy that mark to the skb->priority field where again CAKE
-picks this up.
-
-This change cuts out at least one of the (less intuitive &
-non-scalable) middlemen and permit direct access to skb->mark.

-Subject: [PATCH] sch_cake: Interpret fwmark parameter as a bitmask
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-We initially interpreted the fwmark parameter as a flag that simply turned
-on the feature, using the whole skb->mark field as the index into the CAKE
-tin_order array. However, it is quite common for different applications to
-use different parts of the mask field for their own purposes, each using a
-different mask.
-
-Support this use of subsets of the mark by interpreting the TCA_CAKE_FWMARK
-parameter as a bitmask to apply to the fwmark field when reading it. The
-result will be right-shifted by the number of unset lower bits of the mask
-before looking up the tin.
-
-In the original commit message we also failed to credit Felix Resch with
-originally suggesting the fwmark feature back in 2017; so the Suggested-By
-in this commit covers the whole fwmark feature.

-Subject: [PATCH] sch_cake: Take advantage of skb->hash where appropriate
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-While the other fq-based qdiscs take advantage of skb->hash and doesn't
-recompute it if it is already set, sch_cake does not.
-
-This was a deliberate choice because sch_cake hashes various parts of the
-packet header to support its advanced flow isolation modes. However,
-foregoing the use of skb->hash entirely loses a few important benefits:
-
-- When skb->hash is set by hardware, a few CPU cycles can be saved by not
- hashing again in software.
-
-- Tunnel encapsulations will generally preserve the value of skb->hash from
- before the encapsulation, which allows flow-based qdiscs to distinguish
- between flows even though the outer packet header no longer has flow
- information.
-
-It turns out that we can preserve these desirable properties in many cases,
-while still supporting the advanced flow isolation properties of sch_cake.
-This patch does so by reusing the skb->hash value as the flow_hash part of
-the hashing procedure in cake_hash() only in the following conditions:
-
-- If the skb->hash is marked as covering the flow headers (skb->l4_hash is
- set)
-
-AND
-
-- NAT header rewriting is either disabled, or did not change any values
- used for hashing. The latter is important to match local-origin packets
- such as those of a tunnel endpoint.
-
-The immediate motivation for fixing this was the recent patch to WireGuard
-to preserve the skb->hash on encapsulation. As such, this is also what I
-tested against; with this patch, added latency under load for competing
-flows drops from ~8 ms to sub-1ms on an RRUL test over a WireGuard tunnel
-going through a virtual link shaped to 1Gbps using sch_cake. This matches
-the results we saw with a similar setup using sch_fq_codel when testing the
-WireGuard patch.

-IMPORTANT NOTE
-==============
-
-The content of this patch has been adapted for Linux 4.19
-
-Changes were made in Linux 5.x to add the bad-block limit
-to the metadata available to the driver, adding a parameter
-
-NAND_MEMORG(1, 2048, 128, 64, 1024, 20, 1, 1, 1),
- ^- New bad-block limit
-
-This patch omits that parameter from the upstream patch
-for compatibility with the Linux 4.19 driver.

-Subject: [PATCH 3/3] mtd: spinand: Add support for GigaDevice GD5F1GQ4UFxxG
-
-The GigaDevice GD5F1GQ4UFxxG SPI NAND is in current production devices
-and, while it has the same logical layout as the E-series devices,
-it differs in the SPI interfacing in significant ways.
-
-This support is contingent on previous commits to:
-
- * Add support for two-byte device IDs
- * Define macros for page-read ops with three-byte addresses

-Subject: [PATCH] iio: add IIO_MASSCONCENTRATION channel type
-
-Measuring particulate matter in ug / m3 (micro-grams per cubic meter)
-is de facto standard. Existing air quality sensors usually follow
-this convention and are capable of returning measurements using
-this unit.
-
-IIO currently does not offer suitable channel type for this
-type of measurements hence this patch adds this.
-
-In addition, extra modifiers are introduced used for distinguishing
-between fine pm1, pm2p5 and coarse pm4, pm10 particle measurements, i.e
-IIO_MOD_PM1, IIO_MOD_PM25 and IIO_MOD_PM4, IIO_MOD_PM10.
-
-pmX consists of particles with aerodynamic diameter less or equal to
-X micrometers.

-Subject: [PATCH] iio: chemical: sps30: add support for self cleaning
-
-Self cleaning is especially useful in cases where sensor undergoes
-frequent power on/off cycles. In such scenarios it is recommended to
-turn self cleaning at least once per week in order to maintain reliable
-measurements.
-
-Self cleaning is activated by writing 1 to a dedicated attribute.
-Internal fan accelerates to its maximum speed and keeps spinning
-for about 10 seconds blowing out accumulated dust.

-Subject: [PATCH 602/660] net: phy: Stop with excessive soft reset
-
-While consolidating the PHY reset in phy_init_hw() an unconditionaly
-BMCR soft-reset I became quite trigger happy with those. This was later
-on deactivated for the Generic PHY driver on the premise that a prior
-software entity (e.g: bootloader) might have applied workarounds in
-commit 0878fff1f42c ("net: phy: Do not perform software reset for
-Generic PHY").
-
-Since we have a hook to wire-up a soft_reset callback, just use that and
-get rid of the call to genphy_soft_reset() entirely. This speeds up
-initialization and link establishment for most PHYs out there that do
-not require a reset.
-
-Fixes: 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()")

-Subject: [PATCH 612/660] net: sfp: Stop SFP polling and interrupt handling
- during shutdown
-
-SFP device polling can cause problems during the shutdown process if the
-parent devices of the network controller have been shut down already.
-This problem was seen on the iMX6 platform with PCIe devices, where
-accessing the device after the bus is shut down causes a hang.
-
-Free any acquired GPIO interrupts and stop all delayed work in the SFP
-driver during the shutdown process, so that we ensure that no pending
-operations are still occurring after the SFP shutdown completes.

-Subject: [PATCH 613/660] net: phylink: don't start and stop SGMII PHYs in SFP
- modules twice
-
-SFP modules connected using the SGMII interface have their own PHYs which
-are handled by the struct phylink's phydev field. On the other hand, for
-the modules connected using 1000Base-X interface that field is not set.
-
-Since commit ce0aa27ff3f6 ("sfp: add sfp-bus to bridge between network
-devices and sfp cages") phylink_start() ends up setting the phydev field
-using the sfp-bus infrastructure, which eventually calls phy_start() on it,
-and then calling phy_start() again on the same phydev from phylink_start()
-itself. Similar call sequence holds for phylink_stop(), only in the reverse
-order. This results in WARNs during network interface bringup and shutdown
-when a copper SFP module is connected, as phy_start() and phy_stop() are
-called twice in a row for the same phy_device:

-SFP modules with the 1000Base-X interface are not affected.
-
-Place explicit calls to phy_start() and phy_stop() before enabling or after
-disabling an attached SFP module, where phydev is not yet set (or is
-already unset), so they will be made only from the inside of sfp-bus, if
-needed.

-Subject: [PATCH 615/660] net: sfp: rework upstream interface
-
-The current upstream interface is an all-or-nothing, which is
-sub-optimal for future changes, as it doesn't allow the upstream driver
-to prepare for the SFP module becoming available, as it is at boot.
-
-Switch to a find-sfp-bus, add-upstream, del-upstream, put-sfp-bus
-interface structure instead, which allows the upstream driver to
-prepare for a module being available as soon as add-upstream is called.

-Subject: [PATCH 625/660] net: sfp: control TX_DISABLE and phy only from main
- state machine
-
-We initialise TX_DISABLE when the sfp cage is probed, and then
-maintain its state in the main state machine. However, the module
-state machine:
-- negates it when detecting a newly inserted module when it's already
- guaranteed to be negated.
-- negates it when the module is removed, but the main state machine
- will do this anyway.
-
-Make TX_DISABLE entirely controlled by the main state machine.
-
-The main state machine also probes the module for a PHY, and removes
-the PHY when the the module is removed. Hence, removing the PHY in
-sfp_sm_module_remove() is also redundant, and is a left-over from
-when we tried to probe for the PHY from the module state machine.

-Subject: [PATCH 630/660] net: sfp: track upstream's attachment state in state
- machine
-
-Track the upstream's attachment state in the state machine rather than
-maintaining a boolean, which ensures that we have a strict order of
-ATTACH followed by an UP event - we can never believe that a newly
-attached upstream will be anything but down.
-
-Rearrange the order of state machines so we run the module state
-machine after the upstream device's state machine, so the module state
-machine can check the current state of the device and take action to
-e.g. reset back to empty state when the upstream is detached.
-
-This is to allow the module detection to run independently of the
-network device becoming available.

-
-Switch the power mode switching from the probe, so that we don't
-repeatedly re-probe the SFP device if there is a problem accessing
-the registers at I2C address 0x51.
-
-In splitting this out, we can also fix a bug where we leave the module
-in high-power mode when the upstream device is detached but the module
-is still inserted.

-
-Move the module insertion reporting out of the probe handling, but
-after we have detected that the upstream has attached (since that is
-whom we are reporting insertion to.)
-
-Only report module removal if we had previously reported a module
-insertion.
-
-This gives cleaner semantics, and means we can probe the module before
-we have an upstream attached.

-Subject: [PATCH 633/660] net: sfp: allow sfp to probe slow to initialise GPON
- modules
-
-Some GPON modules (e.g. Huawei MA5671A) take a significant amount of
-time to start responding on the I2C bus, contary to the SFF
-specifications.
-
-Work around this by implementing a two-level timeout strategy, where
-we initially quickly retry for the module, and then use a slower retry
-after we exceed a maximum number of quick attempts.

-Subject: [PATCH 634/660] net: sfp: allow modules with slow diagnostics to
- probe
-
-When a module is inserted, we attempt to read read the ID from address
-0x50. Once we are able to read the ID, we immediately attempt to
-initialise the hwmon support by reading from address 0x51. If this
-fails, then we fall into error state, and assume that the module is
-not usable.
-
-Modules such as the ALCATELLUCENT 3FE46541AA use a real EEPROM for
-I2C address 0x50, which responds immediately. However, address 0x51
-is an emulated, which only becomes available once the on-board firmware
-has booted. This prompts us to fall into the error state.
-
-Since the module may be usable without diagnostics, arrange for the
-hwmon probe independent of the rest of the SFP itself, retrying every
-5s for up to about 60s for the monitoring to become available, and
-print an error message if it doesn't become available.

-Subject: [PATCH 638/660] net: phy: avoid matching all-ones clause 45 PHY IDs
-
-We currently match clause 45 PHYs using any ID read from a MMD marked
-as present in the "Devices in package" registers 5 and 6. However,
-this is incorrect. 45.2 says:
-
- "The definition of the term package is vendor specific and could be
- a chip, module, or other similar entity."
-
-so a package could be more or less than the whole PHY - a PHY could be
-made up of several modules instantiated onto a single chip such as the
-Marvell 88x3310, or some of the MMDs could be disabled according to
-chip configuration, such as the Broadcom 84881.
-
-In the case of Broadcom 84881, the "Devices in package" registers
-contain 0xc000009b, meaning that there is a PHYXS present in the
-package, but all registers in MMD 4 return 0xffff. This leads to our
-matching code incorrectly binding this PHY to one of our generic PHY
-drivers.
-
-This patch changes the way we determine whether to attempt to match a
-MMD identifier, or use it to request a module - if the identifier is
-all-ones, then we skip over it. When reading the identifiers, we
-initialise phydev->c45_ids.device_ids to all-ones, only reading the
-device ID if the "Devices in package" registers indicates we should.
-
-This avoids the generic drivers incorrectly matching on a PHY ID of
-0xffffffff.

-Subject: [PATCH 639/660] net: phylink: fix link mode modification in PHY mode
-
-Modifying the link settings via phylink_ethtool_ksettings_set() and
-phylink_ethtool_set_pauseparam() didn't always work as intended for
-PHY based setups, as calling phylink_mac_config() would result in the
-unresolved configuration being committed to the MAC, rather than the
-configuration with the speed and duplex setting.
-
-This would work fine if the update caused the link to renegotiate,
-but if no settings have changed, phylib won't trigger a renegotiation
-cycle, and the MAC will be left incorrectly configured.
-
-Avoid calling phylink_mac_config() unless we are using an inband mode
-in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as
-introduced in 4.20 to set the PHY settings in
-phylink_ethtool_set_pauseparam().
