      arm64: dts: qcom: sc7180-trogdor: mark bluetooth address as broken · e12e2800
      Johan Hovold authored
      Several Qualcomm Bluetooth controllers lack persistent storage for the
      device address and instead one can be provided by the boot firmware
      using the 'local-bd-address' devicetree property.
      
      The Bluetooth bindings clearly states that the address should be
      specified in little-endian order, but due to a long-standing bug in the
      Qualcomm driver which reversed the address some boot firmware has been
      providing the address in big-endian order instead.
      
      The boot firmware in SC7180 Trogdor Chromebooks is known to be affected
      so mark the 'local-bd-address' property as broken to maintain backwards
      compatibility with older firmware when fixing the underlying driver bug.
      
      Note that ChromeOS always updates the kernel and devicetree in lockstep
      so that there is no need to handle backwards compatibility with older
      devicetrees.

      Revert "Bluetooth: hci_qca: Set BDA quirk bit if fwnode exists in DT" · 4790a73a
      Johan Hovold authored
      This reverts commit 7dcd3e01.
      
      Qualcomm Bluetooth controllers like WCN6855 do not have persistent
      storage for the Bluetooth address and must therefore start as
      unconfigured to allow the user to set a valid address unless one has
      been provided by the boot firmware in the devicetree.
      
      A recent change snuck into v6.8-rc7 and incorrectly started marking the
      default (non-unique) address as valid. This specifically also breaks the
      Bluetooth setup for some user of the Lenovo ThinkPad X13s.
      
      Note that this is the second time Qualcomm breaks the driver this way
      and that this was fixed last year by commit 6945795b ("Bluetooth:
      fix use-bdaddr-property quirk"), which also has some further details.

      octeontx2-af: Fix issue with loading coalesced KPU profiles · 0ba80d96
      Hariprasad Kelam authored
      The current implementation for loading coalesced KPU profiles has
      a limitation.  The "offset" field, which is used to locate profiles
      within the profile is restricted to a u16.
      
      This restricts the number of profiles that can be loaded. This patch
      addresses this limitation by increasing the size of the "offset" field.

      ====================
      gro: various fixes related to UDP tunnels
      
      We found issues when a UDP tunnel endpoint is in a different netns than
      where UDP GRO happens. This kind of setup is actually quite diverse,
      from having one leg of the tunnel on a remove host, to having a tunnel
      between netns (eg. being bridged in another one or on the host). In our
      case that UDP tunnel was geneve.
      
      UDP tunnel packets should not be GROed at the UDP level. The fundamental
      issue here is such packet can't be detected in a foolproof way: we can't
      know by looking at a packet alone and the current logic of looking up
      UDP sockets is fragile (socket could be in another netns, packet could
      be modified in between, etc). Because there is no way to make the GRO
      code to correctly handle those packets in all cases, this series aims at
      two things: making the net stack to correctly behave (as in, no crash
      and no invalid packet) when such thing happens, and in some cases to
      prevent this "early GRO" from happening.
      
      First three patches fix issues when an "UDP tunneled" packet is being
      GROed too early by rx-udp-gro-forwarding or rx-gro-list.
      
      Last patch is preventing locally generated UDP tunnel packets from being
      GROed. This turns out to be more complex than this patch alone as it
      relies on skb->encapsulation which is currently untrusty in some cases
      (see iptunnel_handle_offloads); but that should fix things in practice
      and is acceptable for a fix. Future work is required to improve things
      (prevent all locally generated UDP tunnel packets from being GROed),
      such as fixing the misuse of skb->encapsulation in drivers; but that
      would be net-next material.
      
      Thanks!

      udp: prevent local UDP tunnel packets from being GROed · 64235eab
      Antoine Tenart authored
      GRO has a fundamental issue with UDP tunnel packets as it can't detect
      those in a foolproof way and GRO could happen before they reach the
      tunnel endpoint. Previous commits have fixed issues when UDP tunnel
      packets come from a remote host, but if those packets are issued locally
      they could run into checksum issues.
      
      If the inner packet has a partial checksum the information will be lost
      in the GRO logic, either in udp4/6_gro_complete or in
      udp_gro_complete_segment and packets will have an invalid checksum when
      leaving the host.
      
      Prevent local UDP tunnel packets from ever being GROed at the outer UDP
      level.
      
      Due to skb->encapsulation being wrongly used in some drivers this is
      actually only preventing UDP tunnel packets with a partial checksum to
      be GROed (see iptunnel_handle_offloads) but those were also the packets
      triggering issues so in practice this should be sufficient.

      udp: do not transition UDP GRO fraglist partial checksums to unnecessary · f0b8c303
      Antoine Tenart authored
      UDP GRO validates checksums and in udp4/6_gro_complete fraglist packets
      are converted to CHECKSUM_UNNECESSARY to avoid later checks. However
      this is an issue for CHECKSUM_PARTIAL packets as they can be looped in
      an egress path and then their partial checksums are not fixed.
      
      Different issues can be observed, from invalid checksum on packets to
      traces like:
      
        gen01: hw csum failure
        skb len=3008 headroom=160 headlen=1376 tailroom=0
        mac=(106,14) net=(120,40) trans=160
        shinfo(txflags=0 nr_frags=0 gso(size=0 type=0 segs=0))
        csum(0xffff232e ip_summed=2 complete_sw=0 valid=0 level=0)
        hash(0x77e3d716 sw=1 l4=1) proto=0x86dd pkttype=0 iif=12
        ...
      
      Fix this by only converting CHECKSUM_NONE packets to
      CHECKSUM_UNNECESSARY by reusing __skb_incr_checksum_unnecessary. All
      other checksum types are kept as-is, including CHECKSUM_COMPLETE as
      fraglist packets being segmented back would have their skb->csum valid.

      gro: fix ownership transfer · ed4cccef
      Antoine Tenart authored
      If packets are GROed with fraglist they might be segmented later on and
      continue their journey in the stack. In skb_segment_list those skbs can
      be reused as-is. This is an issue as their destructor was removed in
      skb_gro_receive_list but not the reference to their socket, and then
      they can't be orphaned. Fix this by also removing the reference to the
      socket.

      udp: do not accept non-tunnel GSO skbs landing in a tunnel · 3d010c80
      Antoine Tenart authored
      When rx-udp-gro-forwarding is enabled UDP packets might be GROed when
      being forwarded. If such packets might land in a tunnel this can cause
      various issues and udp_gro_receive makes sure this isn't the case by
      looking for a matching socket. This is performed in
      udp4/6_gro_lookup_skb but only in the current netns. This is an issue
      with tunneled packets when the endpoint is in another netns. In such
      cases the packets will be GROed at the UDP level, which leads to various
      issues later on. The same thing can happen with rx-gro-list.
      
      We saw this with geneve packets being GROed at the UDP level. In such
      case gso_size is set; later the packet goes through the geneve rx path,
      the geneve header is pulled, the offset are adjusted and frag_list skbs
      are not adjusted with regard to geneve. When those skbs hit
      skb_fragment, it will misbehave. Different outcomes are possible
      depending on what the GROed skbs look like; from corrupted packets to
      kernel crashes.
      
      One example is a BUG_ON[1] triggered in skb_segment while processing the
      frag_list. Because gso_size is wrong (geneve header was pulled)
      skb_segment thinks there is "geneve header size" of data in frag_list,
      although it's in fact the next packet. The BUG_ON itself has nothing to
      do with the issue. This is only one of the potential issues.
      
      Looking up for a matching socket in udp_gro_receive is fragile: the
      lookup could be extended to all netns (not speaking about performances)
      but nothing prevents those packets from being modified in between and we
      could still not find a matching socket. It's OK to keep the current
      logic there as it should cover most cases but we also need to make sure
      we handle tunnel packets being GROed too early.
      
      This is done by extending the checks in udp_unexpected_gso: GSO packets
      lacking the SKB_GSO_UDP_TUNNEL/_CSUM bits and landing in a tunnel must
      be segmented.

      xen-netfront: Add missing skb_mark_for_recycle · 03796540

      Notice that skb_mark_for_recycle() is introduced later than fixes tag in
      commit 6a5bcd84 ("page_pool: Allow drivers to hint on SKB recycling").
      
      It is believed that fixes tag were missing a call to page_pool_release_page()
      between v5.9 to v5.14, after which is should have used skb_mark_for_recycle().
      Since v6.6 the call page_pool_release_page() were removed (in
      commit 535b9c61 ("net: page_pool: hide page_pool_release_page()")
      and remaining callers converted (in commit 6bfef2ec ("Merge branch
      'net-page_pool-remove-page_pool_release_page'")).
      
      This leak became visible in v6.8 via commit dba1b8a7 ("mm/page_pool: catch
      page_pool memory leaks").

      inet: inet_defrag: prevent sk release while still in use · 18685451
      Florian Westphal authored
      ip_local_out() and other functions can pass skb->sk as function argument.
      
      If the skb is a fragment and reassembly happens before such function call
      returns, the sk must not be released.
      
      This affects skb fragments reassembled via netfilter or similar
      modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.
      
      Eric Dumazet made an initial analysis of this bug.  Quoting Eric:
        Calling ip_defrag() in output path is also implying skb_orphan(),
        which is buggy because output path relies on sk not disappearing.
      
        A relevant old patch about the issue was :
        8282f274 ("inet: frag: Always orphan skbs inside ip_defrag()")
      
        [..]
      
        net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
        inet socket, not an arbitrary one.
      
        If we orphan the packet in ipvlan, then downstream things like FQ
        packet scheduler will not work properly.
      
        We need to change ip_defrag() to only use skb_orphan() when really
        needed, ie whenever frag_list is going to be used.
      
      Eric suggested to stash sk in fragment queue and made an initial patch.
      However there is a problem with this:
      
      If skb is refragmented again right after, ip_do_fragment() will copy
      head->sk to the new fragments, and sets up destructor to sock_wfree.
      IOW, we have no choice but to fix up sk_wmem accouting to reflect the
      fully reassembled skb, else wmem will underflow.
      
      This change moves the orphan down into the core, to last possible moment.
      As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
      offset into the FRAG_CB, else skb->sk gets clobbered.
      
      This allows to delay the orphaning long enough to learn if the skb has
      to be queued or if the skb is completing the reasm queue.
      
      In the former case, things work as before, skb is orphaned.  This is
      safe because skb gets queued/stolen and won't continue past reasm engine.
      
      In the latter case, we will steal the skb->sk reference, reattach it to
      the head skb, and fix up wmem accouting when inet_frag inflates truesize.
      
      Fixes: 7026b1dd ("netfilter: Pass socket pointer down through okfn().")

      Octeontx2-af: fix pause frame configuration in GMP mode · 40d4b480
      Hariprasad Kelam authored
      The Octeontx2 MAC block (CGX) has separate data paths (SMU and GMP) for
      different speeds, allowing for efficient data transfer.
      
      The previous patch which added pause frame configuration has a bug due
      to which pause frame feature is not working in GMP mode.
      
      This patch fixes the issue by configurating appropriate registers.

      On reworking and splitting the at803x driver, in splitting function of
      at803x PHYs it was added a NULL dereference bug where priv is referenced
      before it's actually allocated and then is tried to write to for the
      is_1000basex and is_fiber variables in the case of at8031, writing on
      the wrong address.
      
      Fix this by correctly setting priv local variable only after
      at803x_probe is called and actually allocates priv in the phydev struct.

      netfilter: arptables: Select NETFILTER_FAMILY_ARP when building arp_tables.c · 15fba562
      Kuniyuki Iwashima authored
      syzkaller started to report a warning below [0] after consuming the
      commit 4654467d ("netfilter: arptables: allow xtables-nft only
      builds").
      
      The change accidentally removed the dependency on NETFILTER_FAMILY_ARP
      from IP_NF_ARPTABLES.
      
      If NF_TABLES_ARP is not enabled on Kconfig, NETFILTER_FAMILY_ARP will
      be removed and some code necessary for arptables will not be compiled.
      
        $ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
        CONFIG_NETFILTER_FAMILY_ARP=y
        # CONFIG_NF_TABLES_ARP is not set
        CONFIG_IP_NF_ARPTABLES=y
      
        $ make olddefconfig
      
        $ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
        # CONFIG_NF_TABLES_ARP is not set
        CONFIG_IP_NF_ARPTABLES=y
      
      So, when nf_register_net_hooks() is called for arptables, it will
      trigger the splat below.
      
      Now IP_NF_ARPTABLES is only enabled by IP_NF_ARPFILTER, so let's
      restore the dependency on NETFILTER_FAMILY_ARP in IP_NF_ARPFILTER.

      netfilter: nf_tables: skip netdev hook unregistration if table is dormant · 216e7bf7
      Pablo Neira Ayuso authored
      Skip hook unregistration when adding or deleting devices from an

      netfilter: nf_tables: reject table flag and netdev basechain updates · 1e1fb6f0
      Pablo Neira Ayuso authored
      netdev basechain updates are stored in the transaction object hook list.
      When setting on the table dormant flag, it iterates over the existing
      hooks in the basechain. Thus, skipping the hooks that are being
      added/deleted in this transaction, which leaves hook registration in
      inconsistent state.
      
      Reject table flag updates in combination with netdev basechain updates
      in the same batch:
      
      - Update table flags and add/delete basechain: Check from basechain update
        path if there are pending flag updates for this table.
      - add/delete basechain and update table flags: Iterate over the transaction
        list to search for basechain updates from the table update path.
      
      In both cases, the batch is rejected. Based on suggestion from Florian Westphal.
