      Linus Torvalds authored
      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for the v5.3 kernel cycle:
      
        Core changes:
      
         - Device links can optionally be added between a pin control producer
           and its consumers. This will affect how the system power management
           is handled: a pin controller will not suspend before all of its
           consumers have been suspended.
      
           This was necessary for the ST Microelectronics STMFX expander and
           need to be tested on other systems as well: it makes sense to make
           this default in the long run.
      
           Right now it is opt-in per driver.
      
         - Drive strength can be specified in microamps. With decreases in
           silicon technology, milliamps isn't granular enough, let's make it
           possible to select drive strengths in microamps.
      
           Right now the Meson (AMlogic) driver needs this.
      
        New drivers:
      
         - New subdriver for the Tegra 194 SoC.
      
         - New subdriver for the Qualcomm SDM845.
      
         - New subdriver for the Qualcomm SM8150.
      
         - New subdriver for the Freescale i.MX8MN (Freescale is now a product
           line of NXP).
      
         - New subdriver for Marvell MV98DX1135.
      
        Driver improvements:
      
         - The Bitmain BM1880 driver now supports pin config in addition to
           muxing.
      
         - The Qualcomm drivers can now reserve some GPIOs as taken aside and
           not usable for users. This is used in ACPI systems to take out some
           GPIO lines used by the BIOS so that noone else (neither kernel nor
           userspace) will play with them by mistake and crash the machine.
      
         - A slew of refurbishing around the Aspeed drivers (board management
           controllers for servers) in preparation for the new Aspeed AST2600
           SoC.
      
         - A slew of improvements over the SH PFC drivers as usual.
      
         - Misc cleanups and fixes"

      Pull io_uring updates from Jens Axboe:
       "This contains:
      
         - Support for recvmsg/sendmsg as first class opcodes.
      
           I don't envision going much further down this path, as there are
           plans in progress to support potentially any system call in an
           async fashion through io_uring. But I think it does make sense to
           have certain core ops available directly, especially those that can
           support a "try this non-blocking" flag/mode. (me)
      
         - Handle generic short reads automatically.
      
           This can happen fairly easily if parts of the buffered read is
           cached. Since the application needs to issue another request for
           the remainder, just do this internally and save kernel/user
           roundtrip while providing a nicer more robust API. (me)
      
         - Support for linked SQEs.
      
           This allows SQEs to depend on each other, enabling an application
           to eg queue a read-from-this-file,write-to-that-file pair. (me)

      ppp: mppe: Revert "ppp: mppe: Add softdep to arc4" · 25a09ce7
      Eric Biggers authored
      Commit 0e5a610b ("ppp: mppe: switch to RC4 library interface"),
      which was merged through the crypto tree for v5.3, changed ppp_mppe.c to
      use the new arc4_crypt() library function rather than access RC4 through
      the dynamic crypto_skcipher API.
      
      Meanwhile commit aad1dcc4 ("ppp: mppe: Add softdep to arc4") was
      merged through the net tree and added a module soft-dependency on "arc4".
      
      The latter commit no longer makes sense because the code now uses the
      "libarc4" module rather than "arc4", and also due to the direct use of
      arc4_crypt(), no module soft-dependency is required.
      
      So revert the latter commit.

       "In this round, we've introduced native swap file support which can

      Pull xfs updates from Darrick Wong:
       "In this release there are a significant amounts of consolidations and
        cleanups in the log code; restructuring of the log to issue struct
        bios directly; new bulkstat ioctls to return v5 fs inode information
        (and fix all the padding problems of the old ioctl); the beginnings of
        multithreaded inode walks (e.g. quotacheck); and a reduction in memory
        usage in the online scrub code leading to reduced runtimes.
      
         - Refactor inode geometry calculation into a single structure instead
           of open-coding pieces everywhere.
      
         - Add online repair to build options.
      
         - Remove unnecessary function call flags and functions.
      
         - Claim maintainership of various loose xfs documentation and header
           files.
      
         - Use struct bio directly for log buffer IOs instead of struct
           xfs_buf.
      
         - Reduce log item boilerplate code requirements.
      
         - Merge log item code spread across too many files.
      
         - Further distinguish between log item commits and cancellations.
      
         - Various small cleanups to the ag small allocator.
      
         - Support cgroup-aware writeback
      
         - libxfs refactoring for mkfs cleanup
      
         - Remove unneeded #includes
      
         - Fix a memory allocation miscalculation in the new log bio code
      
         - Fix bisection problems
      
         - Fix a crash in ioend processing caused by tripping over freeing of
           preallocated transactions
      
         - Split out a generic inode walk mechanism from the bulkstat code,
           hook up all the internal users to use the walking code, then clean
           up bulkstat to serve only the bulkstat ioctls.
      
         - Add a multithreaded iwalk implementation to speed up quotacheck on
           fast storage with many CPUs.
      
         - Remove unnecessary return values in logging teardown functions.
      
         - Supplement the bstat and inogrp structures with new bulkstat and
           inumbers structures that have all the fields we need for v5
           filesystem features and none of the padding problems of their
           predecessors.
      
         - Wire up new ioctls that use the new structures with a much simpler
           bulk_ireq structure at the head instead of the pointerhappy mess we
           had before.
      
         - Enable userspace to constrain bulkstat returns to a single AG or a
           single special inode so that we can phase out a lot of geometry
           guesswork in userspace.
      
         - Reduce memory consumption and zeroing overhead in extended
           attribute scrub code.
      
         - Fix some behavioral regressions in the new bulkstat backend code.

      cxgb4: reduce kernel stack usage in cudbg_collect_mem_region() · 752c2ea2
      Arnd Bergmann authored
      The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several
      hundred kilobytes of kernel stack space. One gets inlined into the other,
      which causes the stack usage to be combined beyond the warning limit
      when building with clang:
      
      drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=]
      
      Restructuring cudbg_collect_mem_region() lets clang do the same
      optimization that gcc does and reuse the stack slots as it can
      see that the large variables are never used together.
      
      A better fix might be to avoid using cudbg_meminfo on the stack
      altogether, but that requires a larger rewrite.

      tipc: ensure head->lock is initialised · d12cffe9
      Chris Packham authored
      tipc_named_node_up() creates a skb list. It passes the list to
      tipc_node_xmit() which has some code paths that can call
      skb_queue_purge() which relies on the list->lock being initialised.
      
      The spin_lock is only needed if the messages end up on the receive path
      but when the list is created in tipc_named_node_up() we don't
      necessarily know if it is going to end up there.
      
      Once all the skb list users are updated in tipc it will then be possible
      to update them to use the unlocked variants of the skb list functions
      and initialise the lock when we know the message will follow the receive
      path.

      ====================
      Fix bugs in NFP flower match offload
      
      This patchset contains bug fixes for corner cases in the match fields of
      flower offloads. The patches ensure that flows that should not be
      supported are not (incorrectly) offloaded. These include rules that match
      on layer 3 and/or 4 data without specified ethernet or ip protocol fields.

      nfp: flower: ensure ip protocol is specified for L4 matches · 103b7c25
      John Hurley authored
      Flower rules on the NFP firmware are able to match on an IP protocol
      field. When parsing rules in the driver, unknown IP protocols are only
      rejected when further matches are to be carried out on layer 4 fields, as
      the firmware will not be able to extract such fields from packets.
      
      L4 protocol dissectors such as FLOW_DISSECTOR_KEY_PORTS are only parsed if
      an IP protocol is specified. This leaves a loophole whereby a rule that
      attempts to match on transport layer information such as port numbers but
      does not explicitly give an IP protocol type can be incorrectly offloaded
      (in this case with wildcard port numbers matches).
      
      Fix this by rejecting the offload of flows that attempt to match on L4
      information, not only when matching on an unknown IP protocol type, but
      also when the protocol is wildcarded.

      nfp: flower: fix ethernet check on match fields · fd262a6d
      John Hurley authored
      NFP firmware does not explicitly match on an ethernet type field. Rather,
      each rule has a bitmask of match fields that can be used to infer the
      ethernet type.
      
      Currently, if a flower rule contains an unknown ethernet type, a check is
      carried out for matches on other fields of the packet. If matches on
      layer 3 or 4 are found, then the offload is rejected as firmware will not
      be able to extract these fields from a packet with an ethernet type it
      does not currently understand.
      
      However, if a rule contains an unknown ethernet type without any L3 (or
      above) matches then this will effectively be offloaded as a rule with a
      wildcarded ethertype. This can lead to misclassifications on the firmware.
      
      Fix this issue by rejecting all flower rules that specify a match on an
      unknown ethernet type.
      
      Further ensure correct offloads by moving the 'L3 and above' check to any
      rule that does not specify an ethernet type and rejecting rules with
      further matches. This means that we can still offload rules with a
      wildcarded ethertype if they only match on L2 fields but will prevent
      rules which match on further fields that we cannot be sure if the firmware
      will be able to extract.

      net/mlx5e: Provide cb_list pointer when setting up tc block on rep · 3929502b

      Recent refactoring of tc block offloads infrastructure introduced new

      extended all users (drivers) with block cb list and provided it to
      flow_block infra missed mlx5 en_rep. This leads to following NULL-pointer

      davinci_cpdma: don't cast dma_addr_t to pointer · c653f61a
      Arnd Bergmann authored
      dma_addr_t may be 64-bit wide on 32-bit architectures, so it is not
      valid to cast between it and a pointer:
      
      drivers/net/ethernet/ti/davinci_cpdma.c: In function 'cpdma_chan_submit_si':
      drivers/net/ethernet/ti/davinci_cpdma.c:1047:12: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

      Solve this by using two separate members in 'struct submit_info'.
      Since this avoids the use of the 'flag' member, the structure does
      not even grow in typical configurations.

      Taehee Yoo authored
      When a vport is deleted, the maximum headroom size would be changed.
      If the vport which has the largest headroom is deleted,
      the new max_headroom would be set.
      But, if the new headroom size is equal to the old headroom size,
      updating routine is unnecessary.

        It's a lot of different patches, all across the tree due to some api
        changes and lots of debugfs cleanups.
      
        Other than the debugfs cleanups, in this set of changes we have:
      
         - bus iteration function cleanups
      
         - scripts/get_abi.pl tool to display and parse Documentation/ABI
           entries in a simple way
      
         - cleanups to Documenatation/ABI/ entries to make them parse easier
           due to typos and other minor things
      
         - default_attrs use for some ktype users

      net/mlx5e: Convert single case statement switch statements into if statements · 9db7e618
      Nathan Chancellor authored
      During the review of commit 1ff2f0fa ("net/mlx5e: Return in default
      case statement in tx_post_resync_params"), Leon and Nick pointed out
      that the switch statements can be converted to single if statements
      that return early so that the code is easier to follow.
