      filemap: Fix serialization adding transparent huge pages to page cache · 00fa15e0
      Alistair Popple authored
      Commit 793917d9 ("mm/readahead: Add large folio readahead")
      introduced support for using large folios for filebacked pages if the
      filesystem supports it.
      
      page_cache_ra_order() was introduced to allocate and add these large
      folios to the page cache. However adding pages to the page cache should
      be serialized against truncation and hole punching by taking
      invalidate_lock. Not doing so can lead to data races resulting in stale
      data getting added to the page cache and marked up-to-date. See commit
      730633f0 ("mm: Protect operations adding pages to page cache with
      invalidate_lock") for more details.
      
      This issue was found by inspection but a testcase revealed it was
      possible to observe in practice on XFS. Fix this by taking
      invalidate_lock in page_cache_ra_order(), to mirror what is done for the
      non-thp case in page_cache_ra_unbounded().

      mm: Clear page->private when splitting or migrating a page · b653db77
      Matthew Wilcox (Oracle) authored
      In our efforts to remove uses of PG_private, we have found folios with
      the private flag clear and folio->private not-NULL.  That is the root
      cause behind 642d51fb ("ceph: check folio PG_private bit instead
      of folio->private").  It can also affect a few other filesystems that
      haven't yet reported a problem.
      
      compaction_alloc() can return a page with uninitialised page->private,
      and rather than checking all the callers of migrate_pages(), just zero
      page->private after calling get_new_page().  Similarly, the tail pages
      from split_huge_page() may also have an uninitialised page->private.

      net: openvswitch: fix parsing of nw_proto for IPv6 fragments · 12378a5a
      Rosemarie O'Riorden authored
      When a packet enters the OVS datapath and does not match any existing
      flows installed in the kernel flow cache, the packet will be sent to
      userspace to be parsed, and a new flow will be created. The kernel and
      OVS rely on each other to parse packet fields in the same way so that
      packets will be handled properly.
      
      As per the design document linked below, OVS expects all later IPv6
      fragments to have nw_proto=44 in the flow key, so they can be correctly
      matched on OpenFlow rules. OpenFlow controllers create pipelines based
      on this design.
      
      This behavior was changed by the commit in the Fixes tag so that
      nw_proto equals the next_header field of the last extension header.
      However, there is no counterpart for this change in OVS userspace,
      meaning that this field is parsed differently between OVS and the
      kernel. This is a problem because OVS creates actions based on what is
      parsed in userspace, but the kernel-provided flow key is used as a match
      criteria, as described in Documentation/networking/openvswitch.rst. This
      leads to issues such as packets incorrectly matching on a flow and thus
      the wrong list of actions being applied to the packet. Such changes in
      packet parsing cannot be implemented without breaking the userspace.
      
      The offending commit is partially reverted to restore the expected
      behavior.
      
      The change technically made sense and there is a good reason that it was
      implemented, but it does not comply with the original design of OVS.
      If in the future someone wants to implement such a change, then it must
      be user-configurable and disabled by default to preserve backwards
      compatibility with existing OVS versions.

      sock: redo the psock vs ULP protection check · e34a07c0
      Jakub Kicinski authored
      Commit 8a59f9d1 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()")
      has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to
      the new tcp_bpf_update_proto() function. I'm guessing that this
      was done to allow creating psocks for non-inet sockets.
      
      Unfortunately the destruction path for psock includes the ULP
      unwind, so we need to fail the sk_psock_init() itself.
      Otherwise if ULP is already present we'll notice that later,
      and call tcp_update_ulp() with the sk_proto of the ULP
      itself, which will most likely result in the ULP looping
      its callbacks.

      virtio_net: fix xdp_rxq_info bug after suspend/resume · 8af52fe9
      Stephan Gerhold authored
      The following sequence currently causes a driver bug warning
      when using virtio_net:
      
        # ip link set eth0 up
        # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem)
        <resume>
        # ip link set eth0 down
      
        Missing register, driver bug
        WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60
        Call trace:
         xdp_rxq_info_unreg+0x58/0x60
         virtnet_close+0x58/0xac
         __dev_close_many+0xac/0x140

         dev_change_flags+0x24/0x64
         do_setlink+0x230/0xdd0
         ...
      
      This happens because virtnet_freeze() frees the receive_queue
      completely (including struct xdp_rxq_info) but does not call
      xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the
      receive_queue again but does not call xdp_rxq_info_reg().
      
      Actually, parts of virtnet_freeze_down() and virtnet_restore_up()
      are almost identical to virtnet_close() and virtnet_open(): only
      the calls to xdp_rxq_info_(un)reg() are missing. This means that
      we can fix this easily and avoid such problems in the future by
      just calling virtnet_close()/open() from the freeze/restore handlers.
      
      Aside from adding the missing xdp_rxq_info calls the only difference
      is that the refill work is only cancelled if netif_running(). However,
      this should not make any functional difference since the refill work
      should only be active if the network interface is actually up.

      igb: Make DMA faster when CPU is active on the PCIe link · 4e0effd9
      Kai-Heng Feng authored
      Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps
      Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which
      will be significantly lower when 1) ASPM is disabled or 2) SoC package
      c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx
      speed can reach to ~950Mbps.
      
      According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC",
      "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so
      set it to 1b for "DMA is considered idle when there is no Rx or Tx AND
      when there are no TLPs indicating that CPU is active detected on the
      PCIe link (such as the host executes CSR or Configuration register read
      or write operation)" and performing Tx should also fall under "active
      CPU on PCIe link" case.
      
      In addition to that, commit b6e0c419 ("igb: Move DMA Coalescing init
      code to separate function.") seems to wrongly changed from enabling
      E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

      net: dsa: qca8k: reduce mgmt ethernet timeout · 85467f7d
      Christian Marangi authored
      The current mgmt ethernet timeout is set to 100ms. This value is too
      big and would slow down any mdio command in case the mgmt ethernet
      packet have some problems on the receiving part.
      Reduce it to just 5ms to handle case when some operation are done on the
      master port that would cause the mgmt ethernet to not work temporarily.

      net: dsa: qca8k: reset cpu port on MTU change · 386228c6
      Christian Marangi authored
      It was discovered that the Documentation lacks of a fundamental detail
      on how to correctly change the MAX_FRAME_SIZE of the switch.
      
      In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, the
      switch panics and cease to send any packet. This cause the mgmt ethernet
      system to not receive any packet (the slow fallback still works) and
      makes the device not reachable. To recover from this a switch reset is
      required.
      
      To correctly handle this, turn off the cpu ports before changing the
      MAX_FRAME_SIZE and turn on again after the value is applied.
      
      Fixes: f58d2598 ("net: dsa: qca8k: implement the port MTU callbacks")
