2025-06-27isofs: fix Y2038 and Y2156 issues in Rock Ridge TF entryJonas 'Sortie' Termansen
[ Upstream commit 5ea45f54c8d6ca2a95b7bd450ee9eb253310bfd3 ] This change implements the Rock Ridge TF entry LONG_FORM bit, which uses the ISO 9660 17-byte date format (up to year 9999, with 10ms precision) instead of the 7-byte date format (up to year 2155, with 1s precision). Previously the LONG_FORM bit was ignored; and isofs would entirely misinterpret the date as the wrong format, resulting in garbage timestamps on the filesystem. The Y2038 issue in iso_date() is fixed by returning a struct timespec64 instead of an int. parse_rock_ridge_inode_internal() is fixed so it does proper bounds checks of the TF entry timestamps.

2025-06-27software node: Correct a OOB check in software_node_get_reference_args()Zijun Hu
[ Upstream commit 31e4e12e0e9609850cefd4b2e1adf782f56337d6 ] software_node_get_reference_args() wants to get @index-th element, so the property value requires at least '(index + 1) * sizeof(*ref)' bytes but that can not be guaranteed by current OOB check, and may cause OOB for malformed property. Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.

2025-06-27net: ethernet: ti: am65-cpsw: handle -EPROBE_DEFERMichael Walle
[ Upstream commit 09737cb80b8686ffca4ed1805fee745d5c85604d ] of_get_mac_address() might fetch the MAC address from NVMEM and that driver might not have been loaded. In that case, -EPROBE_DEFER is returned. Right now, this will trigger an immediate fallback to am65_cpsw_am654_get_efuse_macid() possibly resulting in a random MAC address although the MAC address is stored in the referenced NVMEM. Fix it by handling the -EPROBE_DEFER return code correctly. This also means that the creation of the MDIO device has to be moved to a later stage as -EPROBE_DEFER must not be returned after child devices are created.

2025-06-27wifi: ath12k: using msdu end descriptor to check for rx multicast packetsSarika Sharma
[ Upstream commit cb7433cc5cd4d07175dbc41f5a19966e9fae48be ] Currently, the RX multicast broadcast packet check is performed using bit 15 from the info6 field of the MPDU start descriptor. This check can also be done using bit 9 from the info5 field of the MSDU end descriptor. However, in some scenarios multicast bit is not set when fetched from MPDU start descriptor. Therefore, checking the RX multicast broadcast packet from the MSDU end descriptor is more reliable as it is per MSDU.

2025-06-27vxlan: Do not treat dst cache initialization errors as fatalIdo Schimmel
[ Upstream commit 20c76dadc783759fd3819d289c72be590660cc8b ] FDB entries are allocated in an atomic context as they can be added from the data path when learning is enabled. After converting the FDB hash table to rhashtable, the insertion rate will be much higher (*) which will entail a much higher rate of per-CPU allocations via dst_cache_init(). When adding a large number of entries (e.g., 256k) in a batch, a small percentage (< 0.02%) of these per-CPU allocations will fail [1]. This does not happen with the current code since the insertion rate is low enough to give the per-CPU allocator a chance to asynchronously create new chunks of per-CPU memory. Given that: a. Only a small percentage of these per-CPU allocations fail. b. The scenario where this happens might not be the most realistic one. c. The driver can work correctly without dst caches. The dst_cache_*() APIs first check that the dst cache was properly initialized. d. The dst caches are not always used (e.g., 'tos inherit'). It seems reasonable to not treat these allocation failures as fatal. Therefore, do not bail when dst_cache_init() fails and suppress warnings by specifying '__GFP_NOWARN'. [1] percpu: allocation failed, size=40 align=8 atomic=1, atomic alloc failed, no space left (*) 97% reduction in average latency of vxlan_fdb_update() when adding 256k entries in a batch.

2025-06-27net: bridge: mcast: re-implement br_multicast_{enable, disable}_port functionsYong Wang
[ Upstream commit 4b30ae9adb047dd0a7982975ec3933c529537026 ] When a bridge port STP state is changed from BLOCKING/DISABLED to FORWARDING, the port's igmp query timer will NOT re-arm itself if the bridge has been configured as per-VLAN multicast snooping. Solve this by choosing the correct multicast context(s) to enable/disable port multicast based on whether per-VLAN multicast snooping is enabled or not, i.e. using per-{port, VLAN} context in case of per-VLAN multicast snooping by re-implementing br_multicast_enable_port() and br_multicast_disable_port() functions. Before the patch, the IGMP query does not happen in the last step of the following test sequence, i.e. no growth for tx counter: # ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1 mcast_vlan_snooping 1 mcast_querier 1 mcast_stats_enabled 1 # bridge vlan global set vid 1 dev br1 mcast_snooping 1 mcast_querier 1 mcast_query_interval 100 mcast_startup_query_count 0 # ip link add name swp1 up master br1 type dummy # bridge link set dev swp1 state 0 # ip -j -p stats show dev swp1 group xstats_slave subgroup bridge suite mcast | jq '.[]["multicast"]["igmp_queries"]["tx_v2"]' 1 # sleep 1 # ip -j -p stats show dev swp1 group xstats_slave subgroup bridge suite mcast | jq '.[]["multicast"]["igmp_queries"]["tx_v2"]' 1 # bridge link set dev swp1 state 3 # sleep 2 # ip -j -p stats show dev swp1 group xstats_slave subgroup bridge suite mcast | jq '.[]["multicast"]["igmp_queries"]["tx_v2"]' 1 After the patch, the IGMP query happens in the last step of the test: # ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1 mcast_vlan_snooping 1 mcast_querier 1 mcast_stats_enabled 1 # bridge vlan global set vid 1 dev br1 mcast_snooping 1 mcast_querier 1 mcast_query_interval 100 mcast_startup_query_count 0 # ip link add name swp1 up master br1 type dummy # bridge link set dev swp1 state 0 # ip -j -p stats show dev swp1 group xstats_slave subgroup bridge suite mcast | jq '.[]["multicast"]["igmp_queries"]["tx_v2"]' 1 # sleep 1 # ip -j -p stats show dev swp1 group xstats_slave subgroup bridge suite mcast | jq '.[]["multicast"]["igmp_queries"]["tx_v2"]' 1 # bridge link set dev swp1 state 3 # sleep 2 # ip -j -p stats show dev swp1 group xstats_slave subgroup bridge suite mcast | jq '.[]["multicast"]["igmp_queries"]["tx_v2"]' 3 Signed-off-by: Yong Wang <yongwang@nvidia.com> Reviewed-by: Andy Roulin <aroulin@nvidia.com> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: Petr Machata <petrm@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.

2025-06-27net: bridge: mcast: update multicast contex when vlan state is changedYong Wang
[ Upstream commit 6c131043eaf1be2a6cc2d228f92ceb626fbcc0f3 ] When the vlan STP state is changed, which could be manipulated by "bridge vlan" commands, similar to port STP state, this also impacts multicast behaviors such as igmp query. In the scenario of per-VLAN snooping, there's a need to update the corresponding multicast context to re-arm the port query timer when vlan state becomes "forwarding" etc. Update br_vlan_set_state() function to enable vlan multicast context in such scenario.

2025-06-27Revert "mac80211: Dynamically set CoDel parameters per station"Toke Høiland-Jørgensen
[ Upstream commit 4876376988081d636a4c4e5f03a5556386b49087 ] This reverts commit 484a54c2e597dbc4ace79c1687022282905afba0. The CoDel parameter change essentially disables CoDel on slow stations, with some questionable assumptions, as Dave pointed out in [0]. Quoting from there: But here are my pithy comments as to why this part of mac80211 is so wrong... static void sta_update_codel_params(struct sta_info *sta, u32 thr) { - if (thr && thr < STA_SLOW_THRESHOLD * sta->local->num_sta) { 1) sta->local->num_sta is the number of associated, rather than active, stations. "Active" stations in the last 50ms or so, might have been a better thing to use, but as most people have far more than that associated, we end up with really lousy codel parameters, all the time. Mistake numero uno! 2) The STA_SLOW_THRESHOLD was completely arbitrary in 2016. - sta->cparams.target = MS2TIME(50); This, by itself, was probably not too bad. 30ms might have been better, at the time, when we were battling powersave etc, but 20ms was enough, really, to cover most scenarios, even where we had low rate 2Ghz multicast to cope with. Even then, codel has a hard time finding any sane drop rate at all, with a target this high. - sta->cparams.interval = MS2TIME(300); But this was horrible, a total mistake, that is leading to codel being completely ineffective in almost any scenario on clients or APS. 100ms, even 80ms, here, would be vastly better than this insanity. I'm seeing 5+seconds of delay accumulated in a bunch of otherwise happily fq-ing APs.... 100ms of observed jitter during a flow is enough. Certainly (in 2016) there were interactions with powersave that I did not understand, and still don't, but if you are transmitting in the first place, powersave shouldn't be a problemmmm..... - sta->cparams.ecn = false; At the time we were pretty nervous about ecn, I'm kind of sanguine about it now, and reliably indicating ecn seems better than turning it off for any reason. [...] In production, on p2p wireless, I've had 8ms and 80ms for target and interval for years now, and it works great. I think Dave's arguments above are basically sound on the face of it, and various experimentation with tighter CoDel parameters in the OpenWrt community have show promising results[1]. So I don't think there's any reason to keep this parameter fiddling; hence this revert.

2025-06-27libbpf: Add identical pointer detection to btf_dedup_is_equiv()Alan Maguire
[ Upstream commit 8e64c387c942229c551d0f23de4d9993d3a2acb6 ] Recently as a side-effect of commit ac053946f5c4 ("compiler.h: introduce TYPEOF_UNQUAL() macro") issues were observed in deduplication between modules and kernel BTF such that a large number of kernel types were not deduplicated so were found in module BTF (task_struct, bpf_prog etc). The root cause appeared to be a failure to dedup struct types, specifically those with members that were pointers with __percpu annotations. The issue in dedup is at the point that we are deduplicating structures, we have not yet deduplicated reference types like pointers. If multiple copies of a pointer point at the same (deduplicated) integer as in this case, we do not see them as identical. Special handling already exists to deal with structures and arrays, so add pointer handling here too.

2025-06-27wifi: mac80211: do not offer a mesh path if forwarding is disabledBenjamin Berg
[ Upstream commit cf1b684a06170d253b47d6a5287821de976435bd ] When processing a PREQ the code would always check whether we have a mesh path locally and reply accordingly. However, when forwarding is disabled then we should not reply with this information as we will not forward data packets down that path. Move the check for dot11MeshForwarding up in the function and skip the mesh path lookup in that case. In the else block, set forward to false so that the rest of the function becomes a no-op and the dot11MeshForwarding check does not need to be duplicated. This explains an effect observed in the Freifunk community where mesh forwarding is disabled. In that case a mesh with three STAs and only bad links in between them, individual STAs would occionally have indirect mpath entries. This should not have happened.

2025-06-27bpf: Pass the same orig_call value to trampoline functionsIlya Leoshkevich
[ Upstream commit 94bde253d3ae5d8a01cb958663b12daef1d06574 ] There is currently some confusion in the s390x JIT regarding whether orig_call can be NULL and what that means. Originally the NULL value was used to distinguish the struct_ops case, but this was superseded by BPF_TRAMP_F_INDIRECT (see commit 0c970ed2f87c ("s390/bpf: Fix indirect trampoline generation"). The remaining reason to have this check is that NULL can actually be passed to the arch_bpf_trampoline_size() call - but not to the respective arch_prepare_bpf_trampoline()! call - by bpf_struct_ops_prepare_trampoline(). Remove this asymmetry by passing stub_func to both functions, so that JITs may rely on orig_call never being NULL.

While it can be considered as misconfiguration and handled by XFRM datapath in the same manner as any other SEQ number, let's add validation to easy for packet offloads implementations which need to configure HW with next SEQ to send and not with current SEQ like it is done in core code.

2025-06-27x86/sgx: Prevent attempts to reclaim poisoned pagesAndrew Zaborowski
[ Upstream commit ed16618c380c32c68c06186d0ccbb0d5e0586e59 ] TL;DR: SGX page reclaim touches the page to copy its contents to secondary storage. SGX instructions do not gracefully handle machine checks. Despite this, the existing SGX code will try to reclaim pages that it _knows_ are poisoned. Avoid even trying to reclaim poisoned pages. The longer story: Pages used by an enclave only get epc_page->poison set in arch_memory_failure() but they currently stay on sgx_active_page_list until sgx_encl_release(), with the SGX_EPC_PAGE_RECLAIMER_TRACKED flag untouched. epc_page->poison is not checked in the reclaimer logic meaning that, if other conditions are met, an attempt will be made to reclaim an EPC page that was poisoned. This is bad because 1. we don't want that page to end up added to another enclave and 2. it is likely to cause one core to shut down and the kernel to panic. Specifically, reclaiming uses microcode operations including "EWB" which accesses the EPC page contents to encrypt and write them out to non-SGX memory. Those operations cannot handle MCEs in their accesses other than by putting the executing core into a special shutdown state (affecting both threads with HT.) The kernel will subsequently panic on the remaining cores seeing the core didn't enter MCE handler(s) in time. Call sgx_unmark_page_reclaimable() to remove the affected EPC page from sgx_active_page_list on memory error to stop it being considered for reclaiming. Testing epc_page->poison in sgx_reclaim_pages() would also work but I assume it's better to add code in the less likely paths. The affected EPC page is not added to &node->sgx_poison_page_list until later in sgx_encl_release()->sgx_free_epc_page() when it is EREMOVEd. Membership on other lists doesn't change to avoid changing any of the lists' semantics except for sgx_active_page_list. There's a "TBD" comment in arch_memory_failure() about pre-emptive actions, the goal here is not to address everything that it may imply. This also doesn't completely close the time window when a memory error notification will be fatal (for a not previously poisoned EPC page) -- the MCE can happen after sgx_reclaim_pages() has selected its candidates or even *inside* a microcode operation (actually easy to trigger due to the amount of time spent in them.) The spinlock in sgx_unmark_page_reclaimable() is safe because memory_failure() runs in process context and no spinlocks are held, explicitly noted in a mm/memory-failure.c comment.

2025-06-27tcp: remove zero TCP TS samples for autotuningEric Dumazet
[ Upstream commit d59fc95be9d0fd05ed3ccc11b4a2f832bdf2ee03 ] For TCP flows using ms RFC 7323 timestamp granularity tcp_rcv_rtt_update() can be fed with 1 ms samples, breaking TCP autotuning for data center flows with sub ms RTT. Instead, rely on the window based samples, fed by tcp_rcv_rtt_measure() tcp_rcvbuf_grow() for a 10 second TCP_STREAM sesssion now looks saner.

2025-06-27iommu/amd: Allow matching ACPI HID devices without matching UIDsMario Limonciello
[ Upstream commit 51c33f333bbf7bdb6aa2a327e3a3e4bbb2591511 ] A BIOS upgrade has changed the IVRS DTE UID for a device that no longer matches the UID in the SSDT. In this case there is only one ACPI device on the system with that _HID but the _UID mismatch. IVRS: ``` Subtable Type : F0 [Device Entry: ACPI HID Named Device] Device ID : 0060 Data Setting (decoded below) : 40 INITPass : 0 EIntPass : 0 NMIPass : 0 Reserved : 0 System MGMT : 0 LINT0 Pass : 1 LINT1 Pass : 0 ACPI HID : "MSFT0201" ACPI CID : 0000000000000000 UID Format : 02 UID Length : 09 UID : "\_SB.MHSP" ``` SSDT: ``` Device (MHSP) { Name (_ADR, Zero) // _ADR: Address Name (_HID, "MSFT0201") // _HID: Hardware ID Name (_UID, One) // _UID: Unique ID ``` To handle this case; while enumerating ACPI devices in get_acpihid_device_id() count the number of matching ACPI devices with a matching _HID. If there is exactly one _HID match then accept it even if the UID doesn't match. Other operating systems allow this, but the current IVRS spec leaves some ambiguity whether to allow or disallow it. This should be clarified in future revisions of the spec. Output 'Firmware Bug' for this case to encourage it to be solved in the BIOS.

2025-06-27wifi: ath11k: Fix QMI memory reuse logicMuhammad Usama Anjum
[ Upstream commit cd2e7bae92bd7e65063ab8d04721d2b711ba4cbe ] Firmware requests 2 segments at first. The first segment is of 6799360 whose allocation fails due to dma remapping not available. The success is returned to firmware. Then firmware asks for 22 smaller segments instead of 2 big ones. Those get allocated successfully. At suspend/ hibernation time, these segments aren't freed as they will be reused by firmware after resuming. After resuming, the firmware asks for the 2 segments again with the first segment of 6799360 size. Since chunk->vaddr is not NULL, the type and size are compared with the previous type and size to know if it can be reused or not. Unfortunately, it is detected that it cannot be reused and this first smaller segment is freed. Then we continue to allocate 6799360 size memory which fails and ath11k_qmi_free_target_mem_chunk() is called which frees the second smaller segment as well. Later success is returned to firmware which asks for 22 smaller segments again. But as we had freed 2 segments already, we'll allocate the first 2 new smaller segments again and reuse the remaining 20. Hence 20 small segments are being reused instead of 22. Add skip logic when vaddr is set, but size/type don't match. Use the same skip and success logic as used when dma_alloc_coherent() fails. By skipping, the possibility of resume failure due to kernel failing to allocate memory for QMI can be avoided. kernel: ath11k_pci 0000:03:00.0: failed to allocate dma memory for qmi (524288 B type 1) ath11k_pci 0000:03:00.0: failed to allocate qmi target memory: -22 Tested-on: WCN6855 WLAN.HSP.1.1-03926.13-QCAHSPSWPL_V2_SILICONZ_CE-2.52297.6 Signed-off-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Reviewed-by: Baochen Qiang <quic_bqiang@quicinc.com> Link: https://patch.msgid.link/20250428080242.466901-1-usama.anjum@collabora.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
2025-06-27wifi: ath12k: fix a possible dead lock caused by ab->base_lockBaochen Qiang
[ Upstream commit ef115c265a21e3c11deee7f73bd1061775a7bf20 ] spin_lock/spin_unlock are used in ath12k_reg_chan_list_event to acquire/release ab->base_lock. For now this is safe because that function is only called in soft IRQ context. But ath12k_reg_chan_list_event() will be called from process context in an upcoming patch, and this can result in a deadlock if ab->base_lock is acquired in process context and then soft IRQ occurs on the same CPU and tries to acquire that lock. Fix it by using spin_lock_bh and spin_unlock_bh instead.
