-Subject: [PATCH] kbuild: add macro for controlling warnings to
- linux/compiler.h
-
-I have occasionally run into a situation where it would make sense to
-control a compiler warning from a source file rather than doing so from
-a Makefile using the $(cc-disable-warning, ...) or $(cc-option, ...)
-helpers.
-
-The approach here is similar to what glibc uses, using __diag() and
-related macros to encapsulate a _Pragma("GCC diagnostic ...") statement
-that gets turned into the respective "#pragma GCC diagnostic ..." by
-the preprocessor when the macro gets expanded.
-
-Like glibc, I also have an argument to pass the affected compiler
-version, but decided to actually evaluate that one. For now, this
-supports GCC_4_6, GCC_4_7, GCC_4_8, GCC_4_9, GCC_5, GCC_6, GCC_7,
-GCC_8 and GCC_9. Adding support for CLANG_5 and other interesting
-versions is straightforward here. GNU compilers starting with gcc-4.2
-could support it in principle, but "#pragma GCC diagnostic push"
-was only added in gcc-4.6, so it seems simpler to not deal with those
-at all. The same versions show a large number of warnings already,
-so it seems easier to just leave it at that and not do a more
-fine-grained control for them.
-
-The use cases I found so far include:
-
-- turning off the gcc-8 -Wattribute-alias warning inside of the
- SYSCALL_DEFINEx() macro without having to do it globally.
-
-- Reducing the build time for a simple re-make after a change,
- once we move the warnings from ./Makefile and
- ./scripts/Makefile.extrawarn into linux/compiler.h
-
-- More control over the warnings based on other configurations,
- using preprocessor syntax instead of Makefile syntax. This should make
- it easier for the average developer to understand and change things.
-
-- Adding an easy way to turn the W=1 option on unconditionally
- for a subdirectory or a specific file. This has been requested
- by several developers in the past that want to have their subsystems
- W=1 clean.
-
-- Integrating clang better into the build systems. Clang supports
- more warnings than GCC, and we probably want to classify them
- as default, W=1, W=2 etc, but there are cases in which the
- warnings should be classified differently due to excessive false
- positives from one or the other compiler.
-
-- Adding a way to turn the default warnings into errors (e.g. using
- a new "make E=0" tag) while not also turning the W=1 warnings into
- errors.
-
-This patch for now just adds the minimal infrastructure in order to
-do the first of the list above. As the #pragma GCC diagnostic
-takes precedence over command line options, the next step would be
-to convert a lot of the individual Makefiles that set nonstandard
-options to use __diag() instead.
-
-[paul.burton@mips.com:
- - Rebase atop current master.
- - Add __diag_GCC, or more generally __diag_<compiler>, abstraction to
- avoid code outside of linux/compiler-gcc.h needing to duplicate
- knowledge about different GCC versions.
- - Add a comment argument to __diag_{ignore,warn,error} which isn't
- used in the expansion of the macros but serves to push people to
- document the reason for using them - per feedback from Kees Cook.
- - Translate severity to GCC-specific pragmas in linux/compiler-gcc.h
- rather than using GCC-specific in linux/compiler_types.h.
- - Drop all but GCC 8 macros, since we only need to define macros for
- versions that we need to introduce pragmas for, and as of this
- series that's just GCC 8.
- - Capitalize comments in linux/compiler-gcc.h to match the style of
- the rest of the file.
- - Line up macro definitions with tabs in linux/compiler-gcc.h.]

-Subject: [PATCH] disable -Wattribute-alias warning for SYSCALL_DEFINEx()
-
-gcc-8 warns for every single definition of a system call entry
-point, e.g.:
-
-include/linux/compat.h:56:18: error: 'compat_sys_rt_sigprocmask' alias between functions of incompatible types 'long int(int, compat_sigset_t *, compat_sigset_t *, compat_size_t)' {aka 'long int(int, struct <anonymous> *, struct <anonymous> *, unsigned int)'} and 'long int(long int, long int, long int, long int)' [-Werror=attribute-alias]
- asmlinkage long compat_sys##name(__MAP(x,__SC_DECL,__VA_ARGS__))\
- ^~~~~~~~~~
-include/linux/compat.h:45:2: note: in expansion of macro 'COMPAT_SYSCALL_DEFINEx'
- COMPAT_SYSCALL_DEFINEx(4, _##name, __VA_ARGS__)
- ^~~~~~~~~~~~~~~~~~~~~~
-kernel/signal.c:2601:1: note: in expansion of macro 'COMPAT_SYSCALL_DEFINE4'
- COMPAT_SYSCALL_DEFINE4(rt_sigprocmask, int, how, compat_sigset_t __user *, nset,
- ^~~~~~~~~~~~~~~~~~~~~~
-include/linux/compat.h:60:18: note: aliased declaration here
- asmlinkage long compat_SyS##name(__MAP(x,__SC_LONG,__VA_ARGS__))\
- ^~~~~~~~~~
-
-The new warning seems reasonable in principle, but it doesn't
-help us here, since we rely on the type mismatch to sanitize the
-system call arguments. After I reported this as GCC PR82435, a new
--Wno-attribute-alias option was added that could be used to turn the
-warning off globally on the command line, but I'd prefer to do it a
-little more fine-grained.
-
-Interestingly, turning a warning off and on again inside of
-a single macro doesn't always work, in this case I had to add
-an extra statement inbetween and decided to copy the __SC_TEST
-one from the native syscall to the compat syscall macro. See
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83256 for more details
-about this.
-
-[paul.burton@mips.com:
- - Rebase atop current master.
- - Split GCC & version arguments to __diag_ignore() in order to match
- changes to the preceding patch.
- - Add the comment argument to match the preceding patch.]

-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.

-Subject: [PATCH] tcp: allow drivers to tweak TSQ logic
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-I had many reports that TSQ logic breaks wifi aggregation.
-
-Current logic is to allow up to 1 ms of bytes to be queued into qdisc
-and drivers queues.
-
-But Wifi aggregation needs a bigger budget to allow bigger rates to
-be discovered by various TCP Congestion Controls algorithms.
-
-This patch adds an extra socket field, allowing wifi drivers to select
-another log scale to derive TCP Small Queue credit from current pacing
-rate.
-
-Initial value is 10, meaning that this patch does not change current
-behavior.
-
-We expect wifi drivers to set this field to smaller values (tests have
-been done with values from 6 to 9)
-
-They would have to use following template :
-
-if (skb->sk && skb->sk->sk_pacing_shift != MY_PACING_SHIFT)
- skb->sk->sk_pacing_shift = MY_PACING_SHIFT;

-
-This patch adds a way to enable an external vbus supply in host mode,
-when dwc2 drvvbus signal is not used.
-
-This patch is very similar to the one done in U-Boot dwc2 driver [1]. It
-also adds dynamic vbus supply management depending on the role and state
-of the core.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change is a small cleanup of mtd_device_parse_register(). When
-using MTD_PARTITIONED_MASTER it makes sure a master MTD is registered
-before dealing with partitions. The advantage of this is not mixing
-code handling master MTD with code handling partitions.
-
-This commit doesn't change any behavior except from a slightly different
-failure code path. The new code may need to call del_mtd_device when
-something goes wrong.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This simplifies code a bit by:
-1) Avoiding an extra (tiny) function
-2) Checking for amount of parsed (found) partitions just once
-3) Avoiding clearing/filling struct mtd_partitions manually
-
-With this commit proper functions are called directly from the
-mtd_device_parse_register(). It doesn't need to use minor tricks like
-memsetting struct to 0 to trigger an expected
-mtd_add_device_partitions() behavior.

-Subject: [PATCH] mtd: partitions: add of_match_table parser matching for the
- "ofpart" type
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-In order to properly support compatibility strings as described in the
-bindings/mtd/partition.txt "ofpart" type should be treated as an
-indication for looking into OF. MTD should check "compatible" property
-and search for a matching parser rather than blindly trying the one
-supporting "fixed-partitions".
-
-It also means that existing "fixed-partitions" parser should get renamed
-to use a more meaningful name.
-
-This commit achievies that aim by introducing a new mtd_part_of_parse().
-It works by looking for a matching parser for every string in the
-"compatibility" property (starting with the most specific one).
-
-Please note that driver-specified parsers still take a precedence. It's
-assumed that driver providing a parser type has a good reason for that
-(e.g. having platform data with device-specific info). Also doing
-otherwise could break existing setups. The same applies to using default
-parsers (including "cmdlinepart") as some overwrite DT data with cmdline
-argument.
-
-Partition parsers can now provide an of_match_table to enable
-flash<-->parser matching via device tree as documented in the
-mtd/partition.txt.
-
-This support is currently limited to built-in parsers as it uses
-request_module() and friends. This should be sufficient for most cases
-though as compiling parsers as modules isn't a common choice.

-Subject: [PATCH] mtd: move code adding (registering) partitions to the
- parse_mtd_partitions()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This commit slightly simplifies the code. Every parse_mtd_partitions()
-caller (out of two existing ones) had to add partitions & cleanup parser
-on its own. This moves that responsibility into the function.
-
-That change also allows dropping struct mtd_partitions argument.
-
-There is one minor behavior change caused by this cleanup. If
-parse_mtd_partitions() fails to add partitions (add_mtd_partitions()
-return an error) then mtd_device_parse_register() will still try to
-add (register) fallback partitions. It's a real corner case affecting
-one of uncommon error paths and shouldn't cause any harm.

-Subject: [PATCH] mtd: bcm47xxpart: improve handling TRX partition size
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When bcm47xxpart finds a TRX partition (container) it's supposed to jump
-to the end of it and keep looking for more partitions. TRX and its
-subpartitions are handled by a separate parser.
-
-The problem with old code was relying on the length specified in a TRX
-header. That isn't reliable as TRX is commonly modified to have checksum
-cover only non-changing subpartitions. Otherwise modifying e.g. a rootfs
-would result in CRC32 mismatch and bootloader refusing to boot a
-firmware.
-
-Fix it by trying better to figure out a real TRX size. We can securely
-assume that TRX has to cover all subpartitions and the last one is at
-least of a block size in size. Then compare it with a length field.
-
-This makes code more optimal & reliable thanks to skipping data that
-shouldn't be parsed.

-Subject: [PATCH] mtd: partitions: use DT info for parsing partitions with
- "compatible" prop
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far only flash devices could be described in DT regarding partitions
-parsing. That could be done with "partitions" subnode and a proper
-"compatible" string.
-
-Some devices may use hierarchical (multi-level) layouts and may mix used
-layouts (fixed and dynamic). Describing that in DT is done by specifying
-"compatible" for DT-represented partition plus optionally more
-properties and/or subnodes.
-
-To support such layouts each DT partition has to be checked for
-additional description.
-
-Please note this implementation will work in parallel with support for
-partition type specified for non-DT setups. That already works since
-commit 1a0915be1926 ("mtd: partitions: add support for partition
-parsers").

-
-When allocating a new partition mtd subsystem runs internal tests in the

-dropping some /features/ like write access).
-
-Those constraints don't have to be necessary true for subpartitions. It

-write access) while subpartition may fit blocks nicely. In such case all
-checks should be run again (starting with original flags value).

-0x600d84a5: B50212E (rev B0)

-that need setting master mode manually. It's because they run in slave

-can lead to unreliable connection with massive ping loss.
-
-So far it was reported for a board with BCM47189 SoC and B50212E B1 PHY

-http://ark.intel.com/products/71307/Intel-Ethernet-Connection-I218-LM
-I was told there is massive ping loss.

-Subject: [PATCH] bcma: keep a direct pointer to the struct device
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Accessing struct device is pretty useful/common so having a direct
-pointer:
-1) Simplifies some code
-2) Makes bcma_bus_get_host_dev() unneeded
-3) Allows further improvements like using dev_* printing helpers

-Subject: i2c: gpio: Enable working over slow can_sleep GPIOs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-"Slow" GPIOs (usually those connected over an SPI or an I2C bus) are,
-well, slow in their operation. It is generally a good idea to avoid
-using them for time-critical operation, but sometimes the hardware just
-sucks, and the software has to cope. In addition to that, the I2C bus
-itself does not actually define any strict timing limits; the bus is
-free to go all the way down to DC. The timeouts (and therefore the
-slowest acceptable frequency) are present only in SMBus.
-
-The `can_sleep` is IMHO a wrong concept to use here. My SPI-to-quad-UART
-chip (MAX14830) is connected via a 26MHz SPI bus, and it happily drives
-SCL at 200kHz (5µs pulses) during my benchmarks. That's faster than the
-maximal allowed speed of the traditional I2C.
-
-The previous version of this code did not really block operation over
-slow GPIO pins, anyway. Instead, it just resorted to printing a warning
-with a backtrace each time a GPIO pin was accessed, thereby slowing
-things down even more.
-
-Finally, it's not just me. A similar patch was originally submitted in
-2015 [1].

-Subject: [PATCH] net: bridge: add support for port isolation
-
-This patch adds support for a new port flag - BR_ISOLATED. If it is set
-then isolated ports cannot communicate between each other, but they can
-still communicate with non-isolated ports. The same can be achieved via
-ACLs but they can't scale with large number of ports and also the
-complexity of the rules grows. This feature can be used to achieve
-isolated vlan functionality (similar to pvlan) as well, though currently
-it will be port-wide (for all vlans on the port). The new test in
-should_deliver uses data that is already cache hot and the new boolean
-is used to avoid an additional source port test in should_deliver.

-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.
-
-Fixes: 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")

-Subject: [PATCH] batman-adv: Convert packet.h to uapi header
-
-The header file is used by different userspace programs to inject packets
-or to decode sniffed packets. It should therefore be available to them as
-userspace header.
-
-Also other components in the kernel (like the flow dissector) require
-access to the packet definitions to be able to decode ETH_P_BATMAN ethernet
-packets.

-Subject: [PATCH] flow_dissector: Parse batman-adv unicast headers
-
-The batman-adv unicast packets contain a full layer 2 frame in encapsulated
-form. The flow dissector must therefore be able to parse the batman-adv
-unicast header to reach the layer 2+3 information.
-
- +--------------------+
- | ip(v6)hdr |
- +--------------------+
- | inner ethhdr |
- +--------------------+
- | batadv unicast hdr |
- +--------------------+
- | outer ethhdr |
- +--------------------+
-
-The obtained information from the upper layer can then be used by RPS to
-schedule the processing on separate cores. This allows better distribution
-of multiple flows from the same neighbor to different cores.

-
-The kernel already has defines for this, but they are in uapi exposed
-headers.
-
-Including these from netns.h causes build errors and also adds unneeded
-dependencies on heads that we don't need.
-
-So move these defines to netfilter_defs.h and place the uapi ones
-in ifndef __KERNEL__ to keep them for userspace.

- wrapper again
-
-This reverts commit d3ad2c17b4047
-("netfilter: core: batch nf_unregister_net_hooks synchronize_net calls").
-
-Nothing wrong with it. However, followup patch will delay freeing of hooks
-with call_rcu, so all synchronize_net() calls become obsolete and there

-
-This revert causes a temporary performance degradation when destroying

-Subject: [PATCH 03/11] netfilter: core: remove synchronize_net call if nfqueue
- is used
-
-since commit 960632ece6949b ("netfilter: convert hook list to an array")
-nfqueue no longer stores a pointer to the hook that caused the packet
-to be queued. Therefore no extra synchronize_net() call is needed after
-dropping the packets enqueued by the old rule blob.

-Subject: [PATCH 04/11] netfilter: core: free hooks with call_rcu
-
-Giuseppe Scrivano says:
- "SELinux, if enabled, registers for each new network namespace 6
- netfilter hooks."
-
-Cost for this is high. With synchronize_net() removed:
- "The net benefit on an SMP machine with two cores is that creating a
- new network namespace takes -40% of the original time."
-
-This patch replaces synchronize_net+kvfree with call_rcu().
-We store rcu_head at the tail of a structure that has no fixed layout,
-i.e. we cannot use offsetof() to compute the start of the original
-allocation. Thus store this information right after the rcu head.
-
-We could simplify this by just placing the rcu_head at the start
-of struct nf_hook_entries. However, this structure is used in
-packet processing hotpath, so only place what is needed for that
-at the beginning of the struct.

-Subject: [PATCH 05/11] netfilter: reduce size of hook entry point locations
-
-struct net contains:
-
-struct nf_hook_entries __rcu *hooks[NFPROTO_NUMPROTO][NF_MAX_HOOKS];
-
-which store the hook entry point locations for the various protocol
-families and the hooks.
-
-Using array results in compact c code when doing accesses, i.e.
- x = rcu_dereference(net->nf.hooks[pf][hook]);
-
-but its also wasting a lot of memory, as most families are
-not used.
-
-So split the array into those families that are used, which
-are only 5 (instead of 13). In most cases, the 'pf' argument is
-constant, i.e. gcc removes switch statement.
-
-struct net before:
- /* size: 5184, cachelines: 81, members: 46 */
-after:
- /* size: 4672, cachelines: 73, members: 46 */

-Subject: [PATCH] netfilter: nf_tables: explicit nft_set_pktinfo() call from
- hook path
-
-Instead of calling this function from the family specific variant, this
-reduces the code size in the fast path for the netdev, bridge and inet
-families. After this change, we must call nft_set_pktinfo() upfront from
-the chain hook indirection.

-Subject: [PATCH] netfilter: core: only allow one nat hook per hook point
-
-The netfilter NAT core cannot deal with more than one NAT hook per hook
-location (prerouting, input ...), because the NAT hooks install a NAT null
-binding in case the iptables nat table (iptable_nat hooks) or the
-corresponding nftables chain (nft nat hooks) doesn't specify a nat
-transformation.
-
-Null bindings are needed to detect port collsisions between NAT-ed and
-non-NAT-ed connections.
-
-This causes nftables NAT rules to not work when iptable_nat module is
-loaded, and vice versa because nat binding has already been attached
-when the second nat hook is consulted.
-
-The netfilter core is not really the correct location to handle this
-(hooks are just hooks, the core has no notion of what kinds of side
- effects a hook implements), but its the only place where we can check
-for conflicts between both iptables hooks and nftables hooks without
-adding dependencies.
-
-So add nat annotation to hook_ops to describe those hooks that will
-add NAT bindings and then make core reject if such a hook already exists.
-The annotation fills a padding hole, in case further restrictions appar
-we might change this to a 'u8 type' instead of bool.
-
-iptables error if nft nat hook active:
-iptables -t nat -A POSTROUTING -j MASQUERADE
-iptables v1.4.21: can't initialize iptables table `nat': File exists
-Perhaps iptables or your kernel needs to be upgraded.
-
-nftables error if iptables nat table present:
-nft -f /etc/nftables/ipv4-nat
-/usr/etc/nftables/ipv4-nat:3:1-2: Error: Could not process rule: File exists
-table nat {

-
-We cannot make a direct call to nf_ip6_checksum() because that would
-result in autoloading the 'ipv6' module because of symbol dependencies.
-Therefore, define checksum indirection in nf_ipv6_ops where this really
-belongs to.
-
-For IPv4, we can indeed make a direct function call, which is faster,
-given IPv4 is built-in in the networking code by default. Still,
-CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline
-stub for IPv4 in such case.

-
-This is only used by nf_queue.c and this function comes with no symbol
-dependencies with IPv6, it just refers to structure layouts. Therefore,
-we can replace it by a direct function call from where it belongs.

-Subject: [PATCH] netfilter: move route indirection to struct nf_ipv6_ops
-
-We cannot make a direct call to nf_ip6_route() because that would result
-in autoloading the 'ipv6' module because of symbol dependencies.
-Therefore, define route indirection in nf_ipv6_ops where this really
-belongs to.
-
-For IPv4, we can indeed make a direct function call, which is faster,
-given IPv4 is built-in in the networking code by default. Still,
-CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline
-stub for IPv4 in such case.

-Subject: [PATCH] netfilter: move reroute indirection to struct nf_ipv6_ops
-
-We cannot make a direct call to nf_ip6_reroute() because that would result
-in autoloading the 'ipv6' module because of symbol dependencies.
-Therefore, define reroute indirection in nf_ipv6_ops where this really
-belongs to.
-
-For IPv4, we can indeed make a direct function call, which is faster,
-given IPv4 is built-in in the networking code by default. Still,
-CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline
-stub for IPv4 in such case.

-Subject: [PATCH] netfilter: remove defensive check on malformed packets from
- raw sockets
-
-Users cannot forge malformed IPv4/IPv6 headers via raw sockets that they
-can inject into the stack. Specifically, not for IPv4 since 55888dfb6ba7
-("AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl
-(v2)"). IPv6 raw sockets also ensure that packets have a well-formed
-IPv6 header available in the skbuff.
-
-At quick glance, br_netfilter also validates layer 3 headers and it
-drops malformed both IPv4 and IPv6 packets.
-
-Therefore, let's remove this defensive check all over the place.

-Subject: [PATCH] netfilter: nf_conntrack: add IPS_OFFLOAD status bit
-
-This new bit tells us that the conntrack entry is owned by the flow
-table offload infrastructure.
-
- # cat /proc/net/nf_conntrack
- ipv4 2 tcp 6 src=10.141.10.2 dst=147.75.205.195 sport=36392 dport=443 src=147.75.205.195 dst=192.168.2.195 sport=443 dport=36392 [OFFLOAD] mark=0 zone=0 use=2
-
-Note the [OFFLOAD] tag in the listing.
-
-The timer of such conntrack entries look like stopped from userspace.
-In practise, to make sure the conntrack entry does not go away, the
-conntrack timer is periodically set to an arbitrary large value that
-gets refreshed on every iteration from the garbage collector, so it
-never expires- and they display no internal state in the case of TCP
-flows. This allows us to save a bitcheck from the packet path via
-nf_ct_is_expired().
-
-Conntrack entries that have been offloaded to the flow table
-infrastructure cannot be deleted/flushed via ctnetlink. The flow table
-infrastructure is also responsible for releasing this conntrack entry.

-Subject: [PATCH] netfilter: nf_tables: add flow table netlink frontend
-
-This patch introduces a netlink control plane to create, delete and dump
-flow tables. Flow tables are identified by name, this name is used from
-rules to refer to an specific flow table. Flow tables use the rhashtable
-class and a generic garbage collector to remove expired entries.
-
-This also adds the infrastructure to add different flow table types, so
-we can add one for each layer 3 protocol family.

-Subject: [PATCH] netfilter: add generic flow table infrastructure
-
-This patch defines the API to interact with flow tables, this allows to
-add, delete and lookup for entries in the flow table. This also adds the
-generic garbage code that removes entries that have expired, ie. no
-traffic has been seen for a while.
-
-Users of the flow table infrastructure can delete entries via
-flow_offload_dead(), which sets the dying bit, this signals the garbage
-collector to release an entry from user context.
-

-Subject: [PATCH] netfilter: flow table support for IPv4
-
-This patch adds the IPv4 flow table type, that implements the datapath
-flow table to forward IPv4 traffic. Rationale is:
-
-1) Look up for the packet in the flow table, from the ingress hook.
-2) If there's a hit, decrement ttl and pass it on to the neighbour layer
- for transmission.
-3) If there's a miss, packet is passed up to the classic forwarding
- path.
-
-This patch also supports layer 3 source and destination NAT.

-Subject: [PATCH] netfilter: nf_tables: flow offload expression
-
-Add new instruction for the nf_tables VM that allows us to specify what
-flows are offloaded into a given flow table via name. This new
-instruction creates the flow entry and adds it to the flow table.
-
-Only established flows, ie. we have seen traffic in both directions, are
-added to the flow table. You can still decide to offload entries at a
-later stage via packet counting or checking the ct status in case you
-want to offload assured conntracks.
-
-This new extension depends on the conntrack subsystem.

-Subject: [PATCH] netfilter: nf_tables: remove nhooks field from struct
- nft_af_info
-
-We already validate the hook through bitmask, so this check is
-superfluous. When removing this, this patch is also fixing a bug in the
-new flowtable codebase, since ctx->afi points to the table family
-instead of the netdev family which is where the flowtable is really
-hooked in.

-Subject: [PATCH] netfilter: nf_tables: get rid of pernet families
-
-Now that we have a single table list for each netns, we can get rid of
-one pointer per family and the global afinfo list, thus, shrinking
-struct netns for nftables that now becomes 64 bytes smaller.
-
-And call __nft_release_afinfo() from __net_exit path accordingly to
-release netnamespace objects on removal.

-Subject: [PATCH] netfilter: nft_flow_offload: wait for garbage collector
- to run after cleanup
-
-If netdevice goes down, then flowtable entries are scheduled to be
-removed. Wait for garbage collector to have a chance to run so it can
-delete them from the hashtable.
-
-The flush call might sleep, so hold the nfnl mutex from
-nft_flow_table_iterate() instead of rcu read side lock. The use of the
-nfnl mutex is also implicitly fixing races between updates via nfnetlink
-and netdevice event.

-
-Every flow_offload entry is added into the table twice. Because of this,
-rhashtable_free_and_destroy can't be used, since it would call kfree for
-each flow_offload object twice.
-
-This patch adds a call to nf_flow_table_iterate_cleanup() to schedule
-removal of entries, then there is an explicitly invocation of the
-garbage collector to clean up resources.

-Subject: [PATCH] netfilter: nf_flow_offload: fix use-after-free and a resource
- leak
-
-flow_offload_del frees the flow, so all associated resource must be
-freed before.
-
-Since the ct entry in struct flow_offload_entry was allocated by
-flow_offload_alloc, it should be freed by flow_offload_free to take care
-of the error handling path when flow_offload_add fails.
-
-While at it, make flow_offload_del static, since it should never be
-called directly, only from the gc step

-Subject: [PATCH] netfilter: flowtable infrastructure depends on
- NETFILTER_INGRESS
-
-config NF_FLOW_TABLE depends on NETFILTER_INGRESS. If users forget to
-enable this toggle, flowtable registration fails with EOPNOTSUPP.
-
-Moreover, turn 'select NF_FLOW_TABLE' in every flowtable family flavour
-into dependency instead, otherwise this new dependency on
-NETFILTER_INGRESS causes a warning. This also allows us to remove the
-explicit dependency between family flowtables <-> NF_TABLES and
-NF_CONNTRACK, given they depend on the NF_FLOW_TABLE core that already
-expresses the general dependencies for this new infrastructure.
-
-Moreover, NF_FLOW_TABLE_INET depends on NF_FLOW_TABLE_IPV4 and
-NF_FLOWTABLE_IPV6, which already depends on NF_FLOW_TABLE. So we can get
-rid of direct dependency with NF_FLOW_TABLE.
-
-In general, let's avoid 'select', it just makes things more complicated.

-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] leds: trigger: netdev: fix refcnt leak on interface rename
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Renaming a netdev-trigger-tracked interface was resulting in an
-unbalanced dev_hold().
-
-Example:
-> iw phy phy0 interface add foo type __ap
-> echo netdev > trigger
-> echo foo > device_name
-> ip link set foo name bar
-> iw dev bar del
-[ 237.355366] unregister_netdevice: waiting for bar to become free. Usage count = 1
-[ 247.435362] unregister_netdevice: waiting for bar to become free. Usage count = 1
-[ 257.545366] unregister_netdevice: waiting for bar to become free. Usage count = 1
-
-Above problem was caused by trigger checking a dev->name which obviously
-changes after renaming an interface. It meant missing all further events
-including the NETDEV_UNREGISTER which is required for calling dev_put().
-
-This change fixes that by:
-1) Comparing device struct *address* for notification-filtering purposes
-2) Dropping unneeded NETDEV_CHANGENAME code (no behavior change)
-

-Subject: [PATCH] leds: trigger: netdev: fix handling on interface rename
-
-The NETDEV_CHANGENAME code is not "unneeded" like it is stated in commit
-4cb6560514fa ("leds: trigger: netdev: fix refcnt leak on interface
-rename").
-
-The event was accidentally misinterpreted equivalent to
-NETDEV_UNREGISTER, but should be equivalent to NETDEV_REGISTER.
-
-This was the case in the original code from the openwrt project.
-
-Otherwise, you are unable to set netdev led triggers for (non-existent)
-netdevices, which has to be renamed. This is the case, for example, for
-ppp interfaces in openwrt.

-Subject: [PATCH] tty: serial: exar: generalize RS485 setup
-
-Move the non-board-specific part of the RS485 initialization from
-iot2040_rs485_config function to a new generic function used also for
-other boards.
-This allows using TIOCGRS485 and TIOCSRS485 on boards (such as mPCIe
-serial IO modules) which are hard-wired to RS485 or have jumpers for
-their configurations.

-
-Upstream GCC uses a libgcc function for saving/restoring registers. This
-makes the code bigger, and upstream kernels need to carry that function
-for every single kernel module. Our GCC is patched to avoid those
-references, so we can drop the extra bloat for modules.

-Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
-
-set-dscpmark is a method of storing the DSCP of an ip packet into
-conntrack mark. In combination with a suitable tc filter action
-(act_ctinfo) DSCP values are able to be stored in the mark on egress and
-restored on ingress across links that otherwise alter or bleach DSCP.
-
-This is useful for qdiscs such as CAKE which are able to shape according
-to policies based on DSCP.
-
-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.

-x_tables CONNMARK set-dscpmark target solves the problem of storing the
-DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
-action to restore.
-
-The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
-32bit 'statemask'. The dscp mask must be 6 contiguous bits and
-represents the area where the DSCP will be stored in the connmark. The
-state mask is a minimum 1 bit length mask that must not overlap with the
-dscpmask. It represents a flag which is set when the DSCP has been
-stored in the conntrack mark. 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 state
-mask of zero disables the setting of a status bit/s.
-
-example syntax with a suitably modified iptables user space application:
-
-iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
-
-Would store the DSCP in the top 6 bits of the 32bit mark field, and use
-the LSB of the top byte as the 'DSCP has been stored' marker.
-
-|----0xFC----conntrack mark----000000---|
-| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
-| DSCP | unused | flag |unused |
-|-----------------------0x01---000000---|
- ^ ^
- | |
- ---| Conditional flag
- | set this when dscp
-|-ip diffserv-| stored in mark
-| 6 bits |
-|-------------|
-
-an identically configured tc action to restore looks like:
-
-tc filter show dev eth0 ingress
-filter parent ffff: protocol all pref 10 u32 chain 0
-filter parent ffff: protocol all pref 10 u32 chain 0 fh 800: ht divisor 1
-filter parent ffff: protocol all pref 10 u32 chain 0 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1: not_in_hw
- match 00000000/00000000 at 0
- action order 1: ctinfo zone 0 pipe
- index 2 ref 1 bind 1 dscp 0xfc000000/0x1000000
-
- action order 2: mirred (Egress Redirect to device ifb4eth0) stolen
- index 1 ref 1 bind 1
-
-|----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 |

-Subject: [PATCH v2] MIPS: perf: ath79: Fix perfcount IRQ assignment
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Currently it's not possible to use perf on ath79 due to genirq flags
-mismatch happening on static virtual IRQ 13 which is used for
-performance counters hardware IRQ 5.
-
-On TP-Link Archer C7v5:
-
- CPU0
- 2: 0 MIPS 2 ath9k
- 4: 318 MIPS 4 19000000.eth
- 7: 55034 MIPS 7 timer
- 8: 1236 MISC 3 ttyS0
- 12: 0 INTC 1 ehci_hcd:usb1
- 13: 0 gpio-ath79 2 keys
- 14: 0 gpio-ath79 5 keys
- 15: 31 AR724X PCI 1 ath10k_pci
-
- $ perf top
- genirq: Flags mismatch irq 13. 00014c83 (mips_perf_pmu) vs. 00002003 (keys)
-
-On TP-Link Archer C7v4:
-
- CPU0
- 4: 0 MIPS 4 19000000.eth
- 5: 7135 MIPS 5 1a000000.eth
- 7: 98379 MIPS 7 timer
- 8: 30 MISC 3 ttyS0
- 12: 90028 INTC 0 ath9k
- 13: 5520 INTC 1 ehci_hcd:usb1
- 14: 4623 INTC 2 ehci_hcd:usb2
- 15: 32844 AR724X PCI 1 ath10k_pci
- 16: 0 gpio-ath79 16 keys
- 23: 0 gpio-ath79 23 keys
-
- $ perf top
- genirq: Flags mismatch irq 13. 00014c80 (mips_perf_pmu) vs. 00000080 (ehci_hcd:usb1)
-
-This problem is happening, because currently statically assigned virtual
-IRQ 13 for performance counters is not claimed during the initialization
-of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
-this interrupt isn't available for further use.
-
-So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

-Changes since v1:
-
- I've incorporated two comments which I've received on IRC from blogic and
- I've also reworded the commit message to match the changes in v2 of this
- patch.
-
- * use actual hardware perfcount IRQ 5 instead of the virtual IRQ 13
- * dropped the CONFIG_PERF_EVENTS ifdef around irq_create_mapping

-This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
-page_to_pfn anymore.
-
-The following output was generated with two hacked in printk statements:
-
-printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
-(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
- if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
- mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
-printk("after %p\n", mem_map);
-
-Output:
-
-[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
-[ 0.000000] after 8851b280
-
-As seen in the first line mem_map with subtraction of offset does not equal the
-mem_map after subtraction of ARCH_PFN_OFFSET.
-
-After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
-previously calculated offset is zero for the named platform it is able to boot
-4.4 and 4.9-rc7 again.

-
-When an ethernet device is enslaved to a bridge, and the bridge STP

-packet receiption is blocked.
-
-This breaks control applications like WPA which maybe expecting to
-receive packets to negotiate to bring link up. The bridge needs to

-Subject: mtd: part: add generic parsing of linux,part-probe
-
-This moves the linux,part-probe device tree parsing code from
-physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
-providing a reference to their device tree node in struct
-mtd_part_parser_data.
-
-THIS METHOD HAS BEEN DEPRECATED
-
-Linux supports "compatible" property in the "partitions" subnode now. It
-should be used to specify partitions format (and trigger proper parser
-usage) if needed.

-
-This small patch makes the MIPS FPU emulator optional. The kernel
-kills float-users on systems without a hardware FPU by sending a SIGILL.
-
-Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
-optimizing for size).
-
-Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
----
-v4: rediffed because of patch 1/2, should now work with micromips as well
-v3: updated patch description with size savings.
-v2: incorporated changes suggested by Jonas Gorski
- force the fpu emulator on for micromips: relocating the parts
- of the mmips code in the emulator to other areas would be a
- much larger change; I went the cheap route instead with this.

-Subject: [PATCH] MIPS: Add CPU option reporting to /proc/cpuinfo
-
-Many MIPS CPUs have optional CPU features which are not activates for
-all CPU cores. Print the CPU options which are implemented in the core
-in /proc/cpuinfo. This makes it possible to see what features are
-supported and which are not supported. This should cover all standard
-MIPS extensions, before it only printed information about the main MIPS
-ASEs.

-+ MyLoader is a bootloader which allows the user to define partitions
-+ in flash devices, by putting a table in the second erase block
-+ on the device, similar to a partition table. This table gives the
-+ offsets and lengths of the user defined partitions.
-+
-+ If you need code which can detect and parse these tables, and
-+ register MTD 'partitions' corresponding to each image detected,
-+ enable this option.
-+
-+ You will still need the parsing functions to be called by the driver
-+ for your particular device. It won't happen automatically.

-Subject: [PATCH] mtd: m25p80: allow fallback from spi_flash_read to regular
- SPI transfer
-
-Some flash controllers, e.g. on the ath79 platform can support a fast
-flash read via memory mapping, but only if the flash chip is in
-3-byte address mode.
-
-Since spi_flash_read_supported does not have access to the same data as
-spi_flash_read, the driver can't detect an unsupported call until m25p80
-has decided to use spi_flash_read.
-
-Allow the driver to indicate a fallback to a regular SPI transfer by
-returning -EOPNOTSUPP

-
-on some platforms, erase suspend leads to data corruption and lockups when write
-ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
-rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
-simply disable erase suspend, as it will usually not produce any useful gain on
-the small filesystems used on embedded hardware.

-Subject: [PATCH] mtd: spi-nor: support limiting 4K sectors support based on
- flash size
-
-Some devices need 4K sectors to be able to deal with small flash chips.
-For instance, w25x05 is 64 KiB in size, and without 4K sectors, the
-entire chip is just one erase block.
-On bigger flash chip sizes, using 4K sectors can significantly slow down
-many operations, including using a writable filesystem. There are several
-platforms where it makes sense to use a single kernel on both kinds of
-devices.
-
-To support this properly, allow configuring an upper flash chip size
-limit for 4K sectors support.

-Subject: [PATCH 497/497] mtd: mtdconcat: add dt driver for concat devices
-
-Some mtd drivers like physmap variants have support for concatenating
-multiple mtd devices, but there is no generic way to define such a
-concat device from within the device tree.
-
-This is useful for some SoC boards that use multiple flash chips as
-memory banks of a single mtd device, with partitions spanning chip
-borders.
-
-This commit adds a driver for creating virtual mtd-concat devices. They
-must have a compatible = "mtd-concat" line, and define a list of devices
-to concat in the 'devices' property, for example:
-
-flash {
- compatible = "mtd-concat";
-
- devices = <&flash0 &flash1>;
-
- partitions {
- ...
- };
-};
-
-The driver is added to the very end of the mtd Makefile to increase the
-likelyhood of all child devices already being loaded at the time of
-probing, preventing unnecessary deferred probes.

-Subject: [PATCH] net_sched/codel: do not defer queue length update
-
-When codel wants to drop last packet in ->dequeue() it cannot call
-qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
-about zero qlen and HTB/HFSC will deactivate class. The same class will
-be deactivated second time by caller of ->dequeue(). Currently codel and
-fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
-but there is no active classes.
-
-This patch update parent queue length immediately: just temporary increase
-qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
-if we have skb to return.
-
-This might open another problem in HFSC - now operation peek could fail and
-deactivate parent class.

-Subject: [PATCH] netfilter: nf_flow_table: add hardware offload support
-
-This patch adds the infrastructure to offload flows to hardware, in case
-the nic/switch comes with built-in flow tables capabilities.
-
-If the hardware comes with no hardware flow tables or they have
-limitations in terms of features, the existing infrastructure falls back
-to the software flow table implementation.
-
-The software flow table garbage collector skips entries that resides in
-the hardware, so the hardware will be responsible for releasing this
-flow table entry too via flow_offload_dead().
-
-Hardware configuration, either to add or to delete entries, is done from
-the hardware offload workqueue, to ensure this is done from user context
-given that we may sleep when grabbing the mdio mutex.

-Subject: [PATCH] netfilter: nf_flow_table: support hw offload through
- virtual interfaces
-
-There are hardware offload devices that support offloading VLANs and
-PPPoE devices. Additionally, it is useful to be able to offload packets
-routed through bridge interfaces as well.
-Add support for finding the path to the offload device through these
-virtual interfaces, while collecting useful parameters for the offload
-device, like VLAN ID/protocol, PPPoE session and Ethernet MAC address.
-
-Signed-off-by: Felix Fietkau <nbd@nbd.name>

-Subject: [PATCH] netfilter: nf_flow_table: rework hardware offload timeout
- handling
-
-Some offload implementations send keepalive packets + explicit
-notifications of TCP FIN/RST packets. In this case it is more convenient
-to simply let the driver update flow->timeout handling and use the
-regular flow offload gc step.
-
-For drivers that manage their own lifetime, a separate flag can be set
-to avoid gc timeouts.

-
-MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
-between MAP CEs (mesh mode) without the need to forward such data to a

-Subject: ipv6: allow rejecting with "source address failed policy"
-
-RFC6204 L-14 requires rejecting traffic from invalid addresses with
-ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
-egress policy) on the LAN side, so add an appropriate rule for that.

-Subject: [PATCH] net: add support for threaded NAPI polling
-
-For some drivers (especially 802.11 drivers), doing a lot of work in the NAPI
-poll function does not perform well. Since NAPI poll is bound to the CPU it
-was scheduled from, we can easily end up with a few very busy CPUs spending
-most of their time in softirq/ksoftirqd and some idle ones.
-
-Introduce threaded NAPI for such drivers based on a workqueue. The API is the
-same except for using netif_threaded_napi_add instead of netif_napi_add.
-
-In my tests with mt76 on MT7621 using threaded NAPI + a thread for tx scheduling
-improves LAN->WLAN bridging throughput by 10-50%. Throughput without threaded
-NAPI is wildly inconsistent, depending on the CPU that runs the tx scheduling
-thread.
-
-With threaded NAPI it seems stable and consistent (and higher than the best
-results I got without it).
-
-Based on a patch by Hillf Danton

-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.

-Subject: init: add CONFIG_MANGLE_BOOTARGS and disable it by default
-
-Enabling this option renames the bootloader supplied root=
-and rootfstype= variables, which might have to be know but
-would break the automatisms OpenWrt uses.
