afa4bb7 workqueue: clean up WORK_* constant types, clarify masking Dave Airlie reports that gcc-13.1.1 has started complaining about some of the workqueue code in 32-bit arm builds: kernel/workqueue.c: In function ‘get_work_pwq’: kernel/workqueue.c:713:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 713 | return (void *)(data & WORK_STRUCT_WQ_DATA_MASK); | ^ [ ... a couple of other cases ... ] and while it's not immediately clear exactly why gcc started complaining about it now, I suspect it's some C23-induced enum type handlign fixup in gcc-13 is the cause. Whatever the reason for starting to complain, the code and data types are indeed disgusting enough that the complaint is warranted. The wq code ends up creating various "helper constants" (like that WORK_STRUCT_WQ_DATA_MASK) using an enum type, which is all kinds of confused. The mask needs to be 'unsigned long', not some unspecified enum type. To make matters worse, the actual "mask and cast to a pointer" is repeated a couple of times, and the cast isn't even always done to the right pointer, but - as the error case above - to a 'void *' with then the compiler finishing the job. That's now how we roll in the kernel. So create the masks using the proper types rather than some ambiguous enumeration, and use a nice helper that actually does the type conversion in one well-defined place. Incidentally, this magically makes clang generate better code. That, admittedly, is really just a sign of clang having been seriously confused before, and cleaning up the typing unconfuses the compiler too.

7b59e8a arm64: dts: qcom: sc7280: Mark SCM as dma-coherent for chrome devices Just like for sc7180 devices using the Chrome bootflow (AKA trogdor and IDP), sc7280 devices using the Chrome bootflow also need their firmware marked dma-coherent.

However, on sc7280 devices we were still getting the message at bootup after commit 7bd6680b47fa ("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()"""): qcom_scm firmware:scm: Assign memory protection call failed -22 qcom_rmtfs_mem 9c900000.memory: assign memory failed qcom_rmtfs_mem: probe of 9c900000.memory failed with error -22 We should mark SCM properly just like we did for trogdor.

a54b7fa arm64: dts: qcom: sc7180: Mark SCM as dma-coherent for trogdor Trogdor devices use firmware backed by TF-A instead of Qualcomm's normal TZ. On TF-A we end up mapping memory as cacheable. Specifically, you can see in Trogdor's TF-A code [1] in qti_sip_mem_assign() that we call qti_mmap_add_dynamic_region() with MT_RO_DATA. This translates down to MT_MEMORY instead of MT_NON_CACHEABLE or MT_DEVICE. Apparently Qualcomm's normal TZ implementation maps the memory as non-cacheable. Let's add the "dma-coherent" attribute to the SCM for trogdor. Adding "dma-coherent" like this fixes WiFi on sc7180-trogdor devices. WiFi was broken as of commit 7bd6680b47fa ("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()"""). Specifically at bootup we'd get: qcom_scm firmware:scm: Assign memory protection call failed -22 qcom_rmtfs_mem 94600000.memory: assign memory failed qcom_rmtfs_mem: probe of 94600000.memory failed with error -22 From discussion on the mailing lists [2] and over IRC [3], it was determined that we should always have been tagging the SCM as dma-coherent on trogdor but that the old "invalidate" happened to make things work most of the time. Tagging it properly like this is a much more robust solution.

9a5f0b1 arm64: dts: qcom: sc7180: Mark SCM as dma-coherent for IDP sc7180-idp is, for most intents and purposes, a trogdor device. Specifically, sc7180-idp is designed to run the same style of firmware as trogdor devices. This can be seen from the fact that IDP has the same "Reserved memory changes" in its device tree that trogdor has. Recently it was realized that we need to mark SCM as dma-coherent to match what trogdor's style of firmware (based on TF-A) does [1]. That means we need this dma-coherent tag on IDP as well. Without this, on newer versions of Linux, specifically those with commit 7bd6680b47fa ("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()"""), WiFi will fail to work. At bootup you'll see: qcom_scm firmware:scm: Assign memory protection call failed -22 qcom_rmtfs_mem 94600000.memory: assign memory failed qcom_rmtfs_mem: probe of 94600000.memory failed with error -22 [1] https://lore.kernel.org/r/20230615145253.1.Ic62daa649b47b656b313551d646c4de9a7da4bd4@changeid Fixes: 7bd6680b47fa ("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()""") Fixes: f5ab220d162c ("arm64: dts: qcom: sc7180: Add remoteproc enablers") Signed-off-by: Douglas Anderson <dianders@chromium.org> Link: https://lore.kernel.org/r/20230616081440.v2.2.I3c17d546d553378aa8a0c68c3fe04bccea7cba17@changeid Signed-off-by: Bjorn Andersson <andersson@kernel.org> 22 June 2023, 19:20:12 UTC
c087782 dt-bindings: firmware: qcom,scm: Document that SCM can be dma-coherent Trogdor devices use firmware backed by TF-A instead of Qualcomm's normal TZ. On TF-A we end up mapping memory as cacheable. Specifically, you can see in Trogdor's TF-A code [1] in qti_sip_mem_assign() that we call qti_mmap_add_dynamic_region() with MT_RO_DATA. This translates down to MT_MEMORY instead of MT_NON_CACHEABLE or MT_DEVICE. Let's allow devices like trogdor to be described properly by allowing "dma-coherent" in the SCM node.

2230f9e KVM: Avoid illegal stage2 mapping on invalid memory slot We run into guest hang in edk2 firmware when KSM is kept as running on the host. The edk2 firmware is waiting for status 0x80 from QEMU's pflash device (TYPE_PFLASH_CFI01) during the operation of sector erasing or buffered write. The status is returned by reading the memory region of the pflash device and the read request should have been forwarded to QEMU and emulated by it. Unfortunately, the read request is covered by an illegal stage2 mapping when the guest hang issue occurs. The read request is completed with QEMU bypassed and wrong status is fetched. The edk2 firmware runs into an infinite loop with the wrong status. The illegal stage2 mapping is populated due to same page sharing by KSM at (C) even the associated memory slot has been marked as invalid at (B) when the memory slot is requested to be deleted. It's notable that the active and inactive memory slots can't be swapped when we're in the middle of kvm_mmu_notifier_change_pte() because kvm->mn_active_invalidate_count is elevated, and kvm_swap_active_memslots() will busy loop until it reaches to zero again. Besides, the swapping from the active to the inactive memory slots is also avoided by holding &kvm->srcu in __kvm_handle_hva_range(), corresponding to synchronize_srcu_expedited() in kvm_swap_active_memslots(). CPU-A CPU-B ----- ----- ioctl(kvm_fd, KVM_SET_USER_MEMORY_REGION) kvm_vm_ioctl_set_memory_region kvm_set_memory_region __kvm_set_memory_region kvm_set_memslot(kvm, old, NULL, KVM_MR_DELETE) kvm_invalidate_memslot kvm_copy_memslot kvm_replace_memslot kvm_swap_active_memslots (A) kvm_arch_flush_shadow_memslot (B) same page sharing by KSM kvm_mmu_notifier_invalidate_range_start : kvm_mmu_notifier_change_pte kvm_handle_hva_range __kvm_handle_hva_range kvm_set_spte_gfn (C) : kvm_mmu_notifier_invalidate_range_end Fix the issue by skipping the invalid memory slot at (C) to avoid the illegal stage2 mapping so that the read request for the pflash's status is forwarded to QEMU and emulated by it. In this way, the correct pflash's status can be returned from QEMU to break the infinite loop in the edk2 firmware. We tried a git-bisect and the first problematic commit is cd4c71835228 (" KVM: arm64: Convert to the gfn-based MMU notifier callbacks"). With this, clean_dcache_guest_page() is called after the memory slots are iterated in kvm_mmu_notifier_change_pte(). clean_dcache_guest_page() is called before the iteration on the memory slots before this commit. This change literally enlarges the racy window between kvm_mmu_notifier_change_pte() and memory slot removal so that we're able to reproduce the issue in a practical test case. However, the issue exists since commit d5d8184d35c9 ("KVM: ARM: Memory virtualization setup").

cb09122 btrfs: fix remaining u32 overflows when left shifting stripe_nr There was regression caused by a97699d1d610 ("btrfs: replace map_lookup->stripe_len by BTRFS_STRIPE_LEN") and supposedly fixed by a7299a18a179 ("btrfs: fix u32 overflows when left shifting stripe_nr"). To avoid code churn the fix was open coding the type casts but unfortunately missed one which was still possible to hit [1]. The missing place was assignment of bioc->full_stripe_logical inside btrfs_map_block(). Fix it by adding a helper that does the safe calculation of the offset and use it everywhere even though it may not be strictly necessary due to already using u64 types. This replaces all remaining "<< BTRFS_STRIPE_LEN_SHIFT" calls.

The following patchset contains Netfilter/IPVS fixes for net: 1) Fix UDP segmentation with IPVS tunneled traffic, from Terin Stock. 2) Fix chain binding transaction logic, add a bound flag to rule transactions. Remove incorrect logic in nft_data_hold() and nft_data_release(). 3) Add a NFT_TRANS_PREPARE_ERROR deactivate state to deal with releasing the set/chain as a follow up to 1240eb93f061 ("netfilter: nf_tables: incorrect error path handling with NFT_MSG_NEWRULE") 4) Drop map element references from preparation phase instead of set destroy path, otherwise bogus EBUSY with transactions such as: flush chain ip x y delete chain ip x w where chain ip x y contains jump/goto from set elements. 5) Pipapo set type does not regard generation mask from the walk iteration. 6) Fix reference count underflow in set element reference to stateful object. 7) Several patches to tighten the nf_tables API: - disallow set element updates of bound anonymous set - disallow unbound anonymous set/chain at the end of transaction. - disallow updates of anonymous set. - disallow timeout configuration for anonymous sets. 8) Fix module reference leak in chain updates. 9) Fix nfnetlink_osf module autoload. 10) Fix deletion of basechain when NFTA_CHAIN_HOOK is specified as in iptables-nft.

a9628e8 revert "net: align SO_RCVMARK required privileges with SO_MARK" This reverts commit 1f86123b9749 ("net: align SO_RCVMARK required privileges with SO_MARK") because the reasoning in the commit message is not really correct: SO_RCVMARK is used for 'reading' incoming skb mark (via cmsg), as such it is more equivalent to 'getsockopt(SO_MARK)' which has no priv check and retrieves the socket mark, rather than 'setsockopt(SO_MARK) which sets the socket mark and does require privs. Additionally incoming skb->mark may already be visible if sysctl_fwmark_reflect and/or sysctl_tcp_fwmark_accept are enabled. Furthermore, it is easier to block the getsockopt via bpf (either cgroup setsockopt hook, or via syscall filters) then to unblock it if it requires CAP_NET_RAW/ADMIN. On Android the socket mark is (among other things) used to store the network identifier a socket is bound to. Setting it is privileged, but retrieving it is not. We'd like unprivileged userspace to be able to read the network id of incoming packets (where mark is set via iptables [to be moved to bpf])... An alternative would be to add another sysctl to control whether setting SO_RCVMARK is privilged or not. (or even a MASK of which bits in the mark can be exposed) But this seems like over-engineering... Note: This is a non-trivial revert, due to later merged commit e42c7beee71d ("bpf: net: Consider has_current_bpf_ctx() when testing capable() in sk_setsockopt()") which changed both 'ns_capable' into 'sockopt_ns_capable' calls.

c7c059f selftests: forwarding: Fix race condition in mirror installation When mirroring to a gretap in hardware the device expects to be programmed with the egress port and all the encapsulating headers. This requires the driver to resolve the path the packet will take in the software data path and program the device accordingly. If the path cannot be resolved (in this case because of an unresolved neighbor), then mirror installation fails until the path is resolved. This results in a race that causes the test to sometimes fail. Fix this by setting the neighbor's state to permanent in a couple of tests, so that it is always valid.

533aa0b Merge branch 'mptcp-fixes-for-6-4' Matthieu Baerts says: ==================== mptcp: fixes for 6.4 Patch 1 correctly handles disconnect() failures that can happen in some specific cases: now the socket state is set as unconnected as expected. That fixes an issue introduced in v6.2. Patch 2 fixes a divide by zero bug in mptcp_recvmsg() with a fix similar to a recent one from Eric Dumazet for TCP introducing sk_wait_pending flag. It should address an issue present in MPTCP from almost the beginning, from v5.9. Patch 3 fixes a possible list corruption on passive MPJ even if the race seems very unlikely, better be safe than sorry. The possible issue is present from v5.17. Patch 4 consolidates fallback and non fallback state machines to avoid leaking some MPTCP sockets. The fix is likely needed for versions from v5.11. Patch 5 drops code that is no longer used after the introduction of patch 4/6. This is not really a fix but this patch can probably land in the -net tree as well not to leave unused code. Patch 6 ensures listeners are unhashed before updating their sk status to avoid possible deadlocks when diag info are going to be retrieved with a lock. Even if it should not be visible with the way we are currently getting diag info, the issue is present from v5.17. ==================== Link: https://lore.kernel.org/r/20230620-upstream-net-20230620-misc-fixes-for-v6-4-v1-0-f36aa5eae8b9@tessares.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> 22 June 2023, 05:45:00 UTC
57fc0f1 mptcp: ensure listener is unhashed before updating the sk status The MPTCP protocol access the listener subflow in a lockless manner in a couple of places (poll, diag). That works only if the msk itself leaves the listener status only after that the subflow itself has been closed/disconnected. Otherwise we risk deadlock in diag, as reported by Christoph. Address the issue ensuring that the first subflow (the listener one) is always disconnected before updating the msk socket status.

81c1d02 mptcp: consolidate fallback and non fallback state machine An orphaned msk releases the used resources via the worker, when the latter first see the msk in CLOSED status. If the msk status transitions to TCP_CLOSE in the release callback invoked by the worker's final release_sock(), such instance of the workqueue will not take any action. Additionally the MPTCP code prevents scheduling the worker once the socket reaches the CLOSE status: such msk resources will be leaked. The only code path that can trigger the above scenario is the __mptcp_check_send_data_fin() in fallback mode. Address the issue removing the special handling of fallback socket in __mptcp_check_send_data_fin(), consolidating the state machine for fallback and non fallback socket. Since non-fallback sockets do not send and do not receive data_fin, the mptcp code can update the msk internal status to match the next step in the SM every time data fin (ack) should be generated or received. As a consequence we can remove a bunch of checks for fallback from the fastpath.

56a666c mptcp: fix possible list corruption on passive MPJ At passive MPJ time, if the msk socket lock is held by the user, the new subflow is appended to the msk->join_list under the msk data lock. In mptcp_release_cb()/__mptcp_flush_join_list(), the subflows in that list are moved from the join_list into the conn_list under the msk socket lock. Append and removal could race, possibly corrupting such list. Address the issue splicing the join list into a temporary one while still under the msk data lock. Found by code inspection, the race itself should be almost impossible to trigger in practice.

dad9774 Merge tag 'timers-urgent-2023-06-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer fix from Thomas Gleixner: "A single regression fix for a regression fix: For a long time the tick was aligned to clock MONOTONIC so that the tick event happened at a multiple of nanoseconds per tick starting from clock MONOTONIC = 0. At some point this changed as the refined jiffies clocksource which is used during boot before the TSC or other clocksources becomes usable, was adjusted with a boot offset, so that time 0 is closer to the point where the kernel starts. This broke the assumption in the tick code that when the tick setup happens early on ktime_get() will return a multiple of nanoseconds per tick. As a consequence applications which aligned their periodic execution so that it does not collide with the tick were not longer guaranteed that the tick period starts from time 0. The fix for this regression was to realign the tick when it is initially set up to a multiple of tick periods. That works as long as the underlying tick device supports periodic mode, but breaks under certain conditions when the tick device supports only one shot mode. Depending on the offset, the alignment delta to clock MONOTONIC can get in a range where the minimal programming delta of the underlying clock event device is larger than the calculated delta to the next tick. This results in a boot hang as the tick code tries to play catch up, but as the tick never fires jiffies are not advanced so it keeps trying for ever. Solve this by moving the tick alignement into the NOHZ / HIGHRES enablement code because at that point it is guaranteed that the underlying clocksource is high resolution capable and not longer depending on the tick. This is far before user space starts, so at the point where applications try to align their timers, the old behaviour of the tick happening at a multiple of nanoseconds per tick starting from clock MONOTONIC = 0 is restored" * tag 'timers-urgent-2023-06-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: tick/common: Align tick period during sched_timer setup 21 June 2023, 19:36:34 UTC

9724160 bpf/btf: Accept function names that contain dots When building a kernel with LLVM=1, LLVM_IAS=0 and CONFIG_KASAN=y, LLVM leaves DWARF tags for the "asan.module_ctor" & co symbols. In turn, pahole creates BTF_KIND_FUNC entries for these and this makes the BTF metadata validation fail because they contain a dot. In a dramatic turn of event, this BTF verification failure can cause the netfilter_bpf initialization to fail, causing netfilter_core to free the netfilter_helper hashmap and netfilter_ftp to trigger a use-after-free. The risk of u-a-f in netfilter will be addressed separately but the existence of "asan.module_ctor" debug info under some build conditions sounds like a good enough reason to accept functions that contain dots in BTF. Although using only LLVM=1 is the recommended way to compile clang-based kernels, users can certainly do LLVM=1, LLVM_IAS=0 as well and we still try to support that combination according to Nick. To clarify: - > v5.10 kernel, LLVM=1 (LLVM_IAS=0 is not the default) is recommended, but user can still have LLVM=1, LLVM_IAS=0 to trigger the issue - <= 5.10 kernel, LLVM=1 (LLVM_IAS=0 is the default) is recommended in which case GNU as will be used Fixes: 1dc92851849c ("bpf: kernel side support for BTF Var and DataSec") Signed-off-by: Florent Revest <revest@chromium.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Andrii Nakryiko <andrii@kernel.org> Cc: Yonghong Song <yhs@meta.com> Cc: Nick Desaulniers <ndesaulniers@google.com> Link: https://lore.kernel.org/bpf/20230615145607.3469985-1-revest@chromium.org 21 June 2023, 08:32:22 UTC

This change was introduced in kernel 6.3.0. I am seeing this using 6.3.3. If I run with an earlier kernel (5.15), it does not occur. If I make a simple patch to the 6.3.3 virtio-blk driver, to skip the blk_mq_add_to_batch()call, it does not fail. e.g. kernel 5.15 - this is OK virtio_blk.c,virtblk_done() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { blk_mq_complete_request(req); } kernel 6.3.3 - this fails virtio_blk.c,virtblk_handle_req() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { if (!blk_mq_complete_request_remote(req)) { if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) { virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed } } } If I do, kernel 6.3.3 - this is OK virtio_blk.c,virtblk_handle_req() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { if (!blk_mq_complete_request_remote(req)) { virtblk_request_done(req); //force this here... if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) { virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed } } } Perhaps you might like to fix/test/revert this change...

This fixes a regression in which the link would come up, but no communication was possible. The reverted commit was also removing a comment about DP83867_PHYCR_FORCE_LINK_GOOD, this is not added back in this commits since it seems that this is unrelated to the original code change.

This was asked for to prevent leaks of user events hanging around needing admins to clean them up. - Add persistent logic (but not let user space use it yet) In some cases, having a persistent user event (one that does not get cleaned up automatically) is useful.

4bedf9e netfilter: nf_tables: fix chain binding transaction logic Add bound flag to rule and chain transactions as in 6a0a8d10a366 ("netfilter: nf_tables: use-after-free in failing rule with bound set") to skip them in case that the chain is already bound from the abort path. This patch fixes an imbalance in the chain use refcnt that triggers a WARN_ON on the table and chain destroy path. This patch also disallows nested chain bindings, which is not supported from userspace. The logic to deal with chain binding in nft_data_hold() and nft_data_release() is not correct. The NFT_TRANS_PREPARE state needs a special handling in case a chain is bound but next expressions in the same rule fail to initialize as described by 1240eb93f061 ("netfilter: nf_tables: incorrect error path handling with NFT_MSG_NEWRULE"). The chain is left bound if rule construction fails, so the objects stored in this chain (and the chain itself) are released by the transaction records from the abort path, follow up patch ("netfilter: nf_tables: add NFT_TRANS_PREPARE_ERROR to deal with bound set/chain") completes this error handling. When deleting an existing rule, chain bound flag is set off so the rule expression .destroy path releases the objects.

c8e7968 regmap: spi-avmm: Fix regmap_bus max_raw_write The max_raw_write member of the regmap_spi_avmm_bus structure is defined as: .max_raw_write = SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT SPI_AVMM_VAL_SIZE == 4 and MAX_WRITE_CNT == 1 so this results in a maximum write transfer size of 4 bytes which provides only enough space to transfer the address of the target register. It provides no space for the value to be transferred.

Function btrfs_max_io_len() is to get the length to the stripe boundary. It calculates the full stripe start offset (inside the chunk) by the following code: *full_stripe_start = rounddown(*stripe_nr, nr_data_stripes(map)) << BTRFS_STRIPE_LEN_SHIFT; The calculation itself is fine, but the value returned by rounddown() is dependent on both @stripe_nr (which is u32) and nr_data_stripes() (which returned int). Thus the result is also u32, then we do the left shift, which can overflow u32. If such overflow happens, @full_stripe_start will be a value way smaller than @offset, causing later "full_stripe_len - (offset - *full_stripe_start)" to underflow, thus make later length calculation to have no stripe boundary limit, resulting a write bio to exceed stripe boundary. There are some other locations like this, with a u32 @stripe_nr got left shift, which can lead to a similar overflow. [FIX] Fix all @stripe_nr with left shift with a type cast to u64 before the left shift. Those involved @stripe_nr or similar variables are recording the stripe number inside the chunk, which is small enough to be contained by u32, but their offset inside the chunk can not fit into u32. Thus for those specific left shifts, a type cast to u64 is necessary so this patch does not touch them and the code will be cleaned up in the future to keep the fix minimal.

b79d7c1 net: dsa: introduce preferred_default_local_cpu_port and use on MT7530 Since the introduction of the OF bindings, DSA has always had a policy that in case multiple CPU ports are present in the device tree, the numerically smallest one is always chosen. The MT7530 switch family, except the switch on the MT7988 SoC, has 2 CPU ports, 5 and 6, where port 6 is preferable on the MT7531BE switch because it has higher bandwidth. The MT7530 driver developers had 3 options: - to modify DSA when the MT7531 switch support was introduced, such as to prefer the better port - to declare both CPU ports in device trees as CPU ports, and live with the sub-optimal performance resulting from not preferring the better port - to declare just port 6 in the device tree as a CPU port Of course they chose the path of least resistance (3rd option), kicking the can down the road. The hardware description in the device tree is supposed to be stable - developers are not supposed to adopt the strategy of piecemeal hardware description, where the device tree is updated in lockstep with the features that the kernel currently supports. Now, as a result of the fact that they did that, any attempts to modify the device tree and describe both CPU ports as CPU ports would make DSA change its default selection from port 6 to 5, effectively resulting in a performance degradation visible to users with the MT7531BE switch as can be seen below.

As such, this change proposes that we retroactively modify stable kernels (which don't support the modification of the CPU port assignments, so as to let user space fix the problem and restore the throughput) to keep the mt7530 driver preferring port 6 even with device trees where the hardware is more fully described.

ff22102 net: dsa: mt7530: set all CPU ports in MT7531_CPU_PMAP MT7531_CPU_PMAP represents the destination port mask for trapped-to-CPU frames (further restricted by PCR_MATRIX). Currently the driver sets the first CPU port as the single port in this bit mask, which works fine regardless of whether the device tree defines port 5, 6 or 5+6 as CPU ports. This is because the logic coincides with DSA's logic of picking the first CPU port as the CPU port that all user ports are affine to, by default. An upcoming change would like to influence DSA's selection of the default CPU port to no longer be the first one, and in that case, this logic needs adaptation. Since there is no observed leakage or duplication of frames if all CPU ports are defined in this bit mask, simply include them all.
