+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").

+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).

+
+There are 4 very similar PHYs:

+0x600d84a6: B50212E (rev B1)
+that need setting master mode manually. It's because they run in slave
+mode by default with Automatic Slave/Master configuration disabled which
+can lead to unreliable connection with massive ping loss.
+
+So far it was reported for a board with BCM47189 SoC and B50212E B1 PHY
+connected to the bgmac supported ethernet device. Telling PHY driver to
+setup PHY properly solves this issue.

+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.

+Musl provides its own ethhdr struct definition. Add a guard to prevent

+
+glibc does not implement this header, but when glibc will implement this

+
+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
+is no need anymore for this batching.
+
+This revert causes a temporary performance degradation when destroying
+network namespace, but its resolved with the upcoming call_rcu conversion.

+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.

+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.

+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

+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.
+

+Subject: [PATCH] netfilter: move checksum indirection to struct nf_ipv6_ops
+
+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.

+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: 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.

+This patch adds the IPv6 flow table type, that implements the datapath
+flow table to forward IPv6 traffic.
+
+This patch exports ip6_dst_mtu_forward() that is required to check for
+mtu to pass up packets that need PMTUD handling to the classic
+forwarding path.

+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: fix potential NULL-ptr deref in
+ nf_tables_dump_obj_done()
+
+If there is no NFTA_OBJ_TABLE and NFTA_OBJ_TYPE, the c.data will be NULL in
+nf_tables_getobj(). So before free filter->table in nf_tables_dump_obj_done(),
+we need to check if filter is NULL first.
+
+Fixes: e46abbcc05aa ("netfilter: nf_tables: Allow table names of up to 255 chars")

+Subject: [PATCH] netfilter: nf_tables: add single table list for all families
+
+Place all existing user defined tables in struct net *, instead of
+having one list per family. This saves us from one level of indentation
+in netlink dump functions.
+
+Place pointer to struct nft_af_info in struct nft_table temporarily, as
+we still need this to put back reference module reference counter on
+table removal.
+
+This patch comes in preparation for the removal of struct nft_af_info.

+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

+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: clean up and fix dst handling
+
+dst handling in the code is inconsistent and possibly wrong. In my test,
+skb_dst(skb) holds the dst entry after routing but before NAT, so the
+code could possibly return the same dst entry for both directions of a
+connection.
+Additionally, there was some confusion over the dst entry vs the address
+passed as parameter to rt_nexthop/rt6_nexthop.
+
+Do an explicit dst lookup for both ends of the connection and always use
+the source address for it. When running the IP hook, use the dst entry
+for the opposite direction for determining the route.

+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] ubifs: Handle re-linking of inodes correctly while recovery
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+UBIFS's recovery code strictly assumes that a deleted inode will never
+come back, therefore it removes all data which belongs to that inode
+as soon it faces an inode with link count 0 in the replay list.
+Before O_TMPFILE this assumption was perfectly fine. With O_TMPFILE
+it can lead to data loss upon a power-cut.
+
+Consider a journal with entries like:
+0: inode X (nlink = 0) /* O_TMPFILE was created */
+1: data for inode X /* Someone writes to the temp file */
+2: inode X (nlink = 0) /* inode was changed, xattr, chmod, … */
+3: inode X (nlink = 1) /* inode was re-linked via linkat() */
+
+Upon replay of entry #2 UBIFS will drop all data that belongs to inode X,
+this will lead to an empty file after mounting.
+
+As solution for this problem, scan the replay list for a re-link entry
+before dropping data.
+

+
+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: misc: owl-loader for delayed Atheros ath9k fixup
+
+Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
+need to be able to initialize the PCIe wifi device. Normally, this is done
+during the early stages of booting linux, because the necessary init code
+is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
+However,this isn't possible for devices which have the init code for the
+Atheros chip stored on NAND in an UBI volume. Hence, this module can be
+used to initialze the chip when the user-space is ready to extract the
+init code.

+Subject: MIPS: fix cache flushing for highmem pages
+
+Most cache flush ops were no-op for highmem pages. This led to nasty
+segfaults and (in the case of page_address(page) == NULL) kernel
+crashes.
+
+Fix this by always flushing highmem pages using kmap/kunmap_atomic
+around the actual cache flush. This might be a bit inefficient, but at
+least it's stable.

+
+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.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Make sure only to copy any actual data rather than the whole buffer,
+when releasing the temporary buffer used for unaligned non-isochronous
+transfers.
+
+Taken directly from commit 0efd937e27d5e ("USB: ehci-tegra: fix inefficient
+copy of unaligned buffers")
+
+Tested with Lantiq xRX200 (MIPS) and RPi Model B Rev 2 (ARM)

+Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional
+
+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.

++ This option lets you disable the built-in MIPS FPU (Coprocessor 1)
++ emulator, which handles floating-point instructions on processors
++ without a hardware FPU. It is generally a good idea to keep the
++ emulator built-in, unless you are perfectly sure you have a
++ complete soft-float environment. With the emulator disabled, all

++ uction exception.

+
+If no post-DMA flush is required, and the platform does not provide
+plat_unmap_dma_mem(), there is no need to include unmap or sync_for_cpu
+ops.
+
+With this patch they are compiled out to improve icache footprint

++ MyLoader is a bootloader which allows the user to define partitions

++ on the device, similar to a partition table. This table gives the

++
++ 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.

+ 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

+ 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: ubifs: Add option to create UBI FS version 4 on empty UBI volume
+
+Instead of creating an ubifs file system with format version 5 by
+default on empty UBI volumes add a compile option to create an older ubi
+with file system format version 4 instated. This allows it to be mount
+as a volume on kernel versions < 4.10, which does not support format
+version 5.
+We saw that some people can not access their older data when they
+downgraded from kernel 4.14 to kernel 4.9 to prevent this this option
+would help.

+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

+From: Jonas Gorski <jogo@openwrt.org>
+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.

+
+Upstream introduced ICMPV6_POLICY_FAIL for code 5 of destination
+unreachable, conflicting with our name.
+
+Add appropriate defines to allow our code to build with the new
+name until we have updated our local patches for older kernels

+Many embedded devices have information such as mac addresses stored inside mtd

+Subject: libata: add ledtrig support
+
+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

+Cc: Linus Walleij <linus.walleij@linaro.org>,

+
+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 PCIe boards which are hard-wired to RS485
