net/sctp: fix race condition in sctp_destroy_sock
commit b166a20 upstream. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock held and sp->do_auto_asconf is true, then an element is removed from the auto_asconf_splist without any proper locking. This can happen in the following functions: 1. In sctp_accept, if sctp_sock_migrate fails. 2. In inet_create or inet6_create, if there is a bpf program attached to BPF_CGROUP_INET_SOCK_CREATE which denies creation of the sctp socket. The bug is fixed by acquiring addr_wq_lock in sctp_destroy_sock instead of sctp_close. This addresses CVE-2021-23133.

mtd: rawnand: mtk: Fix WAITRDY break condition and timeout
[ Upstream commit 2fb164f ] This fixes NAND_OP_WAITRDY_INSTR operation in the driver. Without this change the driver waits till the system is busy, but we should wait till the busy flag is cleared. The readl_poll_timeout() function gets a break condition, not a wait condition. In addition fix the timeout. The timeout_ms is given in ms, but the readl_poll_timeout() function takes the timeout in us. Multiple the given timeout by 1000 to convert it. Without this change, the driver does not work at all, it doesn't even identify the NAND chip.

Input: nspire-keypad - enable interrupts only when opened
[ Upstream commit 69d5ff3 ] The driver registers an interrupt handler in _probe, but didn't configure them until later when the _open function is called. In between, the keypad can fire an IRQ due to touchpad activity, which the handler ignores. This causes the kernel to disable the interrupt, blocking the keypad from working. Fix this by disabling interrupts before registering the handler. Additionally, disable them in _close, so that they're only enabled while open.

dmaengine: Fix a double free in dma_async_device_register
[ Upstream commit ea45b60 ] In the first list_for_each_entry() macro of dma_async_device_register, it gets the chan from list and calls __dma_async_device_channel_register (..,chan). We can see that chan->local is allocated by alloc_percpu() and it is freed chan->local by free_percpu(chan->local) when __dma_async_device_channel_register() failed. But after __dma_async_device_channel_register() failed, the caller will goto err_out and freed the chan->local in the second time by free_percpu(). The cause of this problem is forget to set chan->local to NULL when chan->local was freed in __dma_async_device_channel_register(). My patch sets chan->local to NULL when the callee failed to avoid double free.

xfrm: BEET mode doesn't support fragments for inner packets
[ Upstream commit 68dc022 ] BEET mode replaces the IP(6) Headers with new IP(6) Headers when sending packets. However, when it's a fragment before the replacement, currently kernel keeps the fragment flag and replace the address field then encaps it with ESP. It would cause in RX side the fragments to get reassembled before decapping with ESP, which is incorrect. In Xiumei's testing, these fragments went over an xfrm interface and got encapped with ESP in the device driver, and the traffic was broken. I don't have a good way to fix it, but only to warn this out in dmesg.

ASoC: max98373: Changed amp shutdown register as volatile
[ Upstream commit a23f909 ] 0x20FF(amp global enable) register was defined as non-volatile, but it is not. Overheating, overcurrent can cause amp shutdown in hardware. 'regmap_write' compare register readback value before writing to avoid same value writing. 'regmap_read' just read cache not actual hardware value for the non-volatile register. When amp is internally shutdown by some reason, next 'AMP ON' command can be ignored because regmap think amp is already ON.

gpu/xen: Fix a use after free in xen_drm_drv_init
[ Upstream commit 52762ef ] In function displback_changed, has the call chain displback_connect(front_info)->xen_drm_drv_init(front_info). We can see that drm_info is assigned to front_info->drm_info and drm_info is freed in fail branch in xen_drm_drv_init(). Later displback_disconnect(front_info) is called and it calls xen_drm_drv_fini(front_info) cause a use after free by drm_info = front_info->drm_info statement. My patch has done two things. First fixes the fail label which drm_info = kzalloc() failed and still free the drm_info. Second sets front_info->drm_info to NULL to avoid uaf.

neighbour: Disregard DEAD dst in neigh_update
[ Upstream commit d47ec7a ] After a short network outage, the dst_entry is timed out and put in DST_OBSOLETE_DEAD. We are in this code because arp reply comes from this neighbour after network recovers. There is a potential race condition that dst_entry is still in DST_OBSOLETE_DEAD. With that, another neighbour lookup causes more harm than good. In best case all packets in arp_queue are lost. This is counterproductive to the original goal of finding a better path for those packets. I observed a worst case with 4.x kernel where a dst_entry in DST_OBSOLETE_DEAD state is associated with loopback net_device. It leads to an ethernet header with all zero addresses. A packet with all zero source MAC address is quite deadly with mac80211, ath9k and 802.11 block ack. It fails ieee80211_find_sta_by_ifaddr in ath9k (xmit.c). Ath9k flushes tx queue (ath_tx_complete_aggr). BAW (block ack window) is not updated. BAW logic is damaged and ath9k transmission is disabled.

ARM: omap1: fix building with clang IAS

Apparently gas does not care because we first add and then subtract this number, leading to the immediate value to be the same regardless of the specific definition of NR_IRQS_LEGACY. Neither the way that 'gas' just silently builds this file, nor the way that clang IAS makes nonsensical suggestions for how to fix it is great. Fortunately there is an easy fix, which is to #include the header that contains the definition.

Input: s6sy761 - fix coordinate read bit shift
commit 30b3f68 upstream. The touch coordinate register contains the following: byte 3 byte 2 byte 1 +--------+--------+ +-----------------+ +-----------------+ | | | | | | | | X[3:0] | Y[3:0] | | Y[11:4] | | X[11:4] | | | | | | | | +--------+--------+ +-----------------+ +-----------------+ Bytes 2 and 1 need to be shifted left by 4 bits, the least significant nibble of each is stored in byte 3. Currently they are only being shifted by 3 causing the reported coordinates to be incorrect. This matches downstream examples, and has been confirmed on my device (OnePlus 7 Pro).

dm verity fec: fix misaligned RS roots IO
commit 8ca7cab upstream. commit df7b59b ("dm verity: fix FEC for RS roots unaligned to block size") introduced the possibility for misaligned roots IO relative to the underlying device's logical block size. E.g. Android's default RS roots=2 results in dm_bufio->block_size=1024, which causes the following EIO if the logical block size of the device is 4096, given v->data_dev_block_bits=12: E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5 Fix this by onlu using f->roots for dm_bufio blocksize IFF it is aligned to v->data_dev_block_bits.

readdir: make sure to verify directory entry for legacy interfaces too
commit 0c93ac6 upstream. This does the directory entry name verification for the legacy "fillonedir" (and compat) interface that goes all the way back to the dark ages before we had a proper dirent, and the readdir() system call returned just a single entry at a time. Nobody should use this interface unless you still have binaries from 1991, but let's do it right. This came up during discussions about unsafe_copy_to_user() and proper checking of all the inputs to it, as the networking layer is looking to use it in a few new places. So let's make sure the _old_ users do it all right and proper, before we add new ones. See also commit 8a23eb8 ("Make filldir[64]() verify the directory entry filename is valid") which did the proper modern interfaces that people actually use. It had a note: Note that I didn't bother adding the checks to any legacy interfaces that nobody uses. which this now corrects. Note that we really don't care about POSIX and the presense of '/' in a directory entry, but verify_dirent_name() also ends up doing the proper name length verification which is what the input checking discussion was about. [ Another option would be to remove the support for this particular very old interface: any binaries that use it are likely a.out binaries, and they will no longer run anyway since we removed a.out binftm support in commit eac6165 ("x86: Deprecate a.out support"). But I'm not sure which came first: getdents() or ELF support, so let's pretend somebody might still have a working binary that uses the legacy readdir() case.. ] Link: https://lore.kernel.org/lkml/CAHk-=wjbvzCAhAtvG0d81W5o0-KT5PPTHhfJ5ieDFq+bGtgOYg@mail.gmail.com/ Acked-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

arm64: alternatives: Move length validation in alternative_{insn, endif}
commit 22315a2 upstream. After commit 2decad9 ("arm64: mte: Ensure TIF_MTE_ASYNC_FAULT is set atomically"), LLVM's integrated assembler fails to build entry.S: <instantiation>:5:7: error: expected assembly-time absolute expression .org . - (664b-663b) + (662b-661b) ^ <instantiation>:6:7: error: expected assembly-time absolute expression .org . - (662b-661b) + (664b-663b) ^ The root cause is LLVM's assembler has a one-pass design, meaning it cannot figure out these instruction lengths when the .org directive is outside of the subsection that they are in, which was changed by the .arch_extension directive added in the above commit. Apply the same fix from commit 966a0ac ("arm64/alternatives: move length validation inside the subsection") to the alternative_endif macro, shuffling the .org directives so that the length validation happen will always happen in the same subsections. alternative_insn has not shown any issue yet but it appears that it could have the same issue in the future so just preemptively change it.

scsi: libsas: Reset num_scatter if libata marks qc as NODATA
commit 176ddd8 upstream. When the cache_type for the SCSI device is changed, the SCSI layer issues a MODE_SELECT command. The caching mode details are communicated via a request buffer associated with the SCSI command with data direction set as DMA_TO_DEVICE (scsi_mode_select()). When this command reaches the libata layer, as a part of generic initial setup, libata layer sets up the scatterlist for the command using the SCSI command (ata_scsi_qc_new()). This command is then translated by the libata layer into ATA_CMD_SET_FEATURES (ata_scsi_mode_select_xlat()). The libata layer treats this as a non-data command (ata_mselect_caching()), since it only needs an ATA taskfile to pass the caching on/off information to the device. It does not need the scatterlist that has been setup, so it does not perform dma_map_sg() on the scatterlist (ata_qc_issue()). Unfortunately, when this command reaches the libsas layer (sas_ata_qc_issue()), libsas layer sees it as a non-data command with a scatterlist. It cannot extract the correct DMA length since the scatterlist has not been mapped with dma_map_sg() for a DMA operation. When this partially constructed SAS task reaches pm80xx LLDD, it results in the following warning: "pm80xx_chip_sata_req 6058: The sg list address start_addr=0x0000000000000000 data_len=0x0end_addr_high=0xffffffff end_addr_low=0xffffffff has crossed 4G boundary" Update libsas to handle ATA non-data commands separately so num_scatter and total_xfer_len remain 0.

libnvdimm/region: Fix nvdimm_has_flush() to handle ND_REGION_ASYNC
commit a2948b1 upstream. In case a platform doesn't provide explicit flush-hints but provides an explicit flush callback via ND_REGION_ASYNC region flag, then nvdimm_has_flush() still returns '0' indicating that writes do not require flushing. This happens on PPC64 with patch at [1] applied, where 'deep_flush' of a region was denied even though an explicit flush function was provided. Fix this by adding a condition to nvdimm_has_flush() to test for the ND_REGION_ASYNC flag on the region and see if a 'region->flush' callback is assigned.

netfilter: bridge: add pre_exit hooks for ebtable unregistration
commit 7ee3c61 upstream. Just like ip/ip6/arptables, the hooks have to be removed, then synchronize_rcu() has to be called to make sure no more packets are being processed before the ruleset data is released. Place the hook unregistration in the pre_exit hook, then call the new ebtables pre_exit function from there. Years ago, when first netns support got added for netfilter+ebtables, this used an older (now removed) netfilter hook unregister API, that did a unconditional synchronize_rcu(). Now that all is done with call_rcu, ebtable_{filter,nat,broute} pernet exit handlers may free the ebtable ruleset while packets are still in flight. This can only happens on module removal, not during netns exit. The new function expects the table name, not the table struct. This is because upcoming patch set (targeting -next) will remove all net->xt.{nat,filter,broute}_table instances, this makes it necessary to avoid external references to those member variables. The existing APIs will be converted, so follow the upcoming scheme of passing name + hook type instead.

net: Make tcp_allowed_congestion_control readonly in non-init netns
commit 97684f0 upstream. Currently, tcp_allowed_congestion_control is global and writable; writing to it in any net namespace will leak into all other net namespaces. tcp_available_congestion_control and tcp_allowed_congestion_control are the only sysctls in ipv4_net_table (the per-netns sysctl table) with a NULL data pointer; their handlers (proc_tcp_available_congestion_control and proc_allowed_congestion_control) have no other way of referencing a struct net. Thus, they operate globally. Because ipv4_net_table does not use designated initializers, there is no easy way to fix up this one "bad" table entry. However, the data pointer updating logic shouldn't be applied to NULL pointers anyway, so we instead force these entries to be read-only. These sysctls used to exist in ipv4_table (init-net only), but they were moved to the per-net ipv4_net_table, presumably without realizing that tcp_allowed_congestion_control was writable and thus introduced a leak. Because the intent of that commit was only to know (i.e. read) "which congestion algorithms are available or allowed", this read-only solution should be sufficient. The logic added in recent commit 31c4d2f: ("net: Ensure net namespace isolation of sysctls") does not and cannot check for NULL data pointers, because other table entries (e.g. /proc/sys/net/netfilter/nf_log/) have .data=NULL but use other methods (.extra2) to access the struct net.

i40e: fix the panic when running bpf in xdpdrv mode
commit 4e39a07 upstream. Fix this panic by adding more rules to calculate the value of @rss_size_max which could be used in allocating the queues when bpf is loaded, which, however, could cause the failure and then trigger the NULL pointer of vsi->rx_rings. Prio to this fix, the machine doesn't care about how many cpus are online and then allocates 256 queues on the machine with 32 cpus online actually. Once the load of bpf begins, the log will go like this "failed to get tracking for 256 queues for VSI 0 err -12" and this "setup of MAIN VSI failed". Thus, I attach the key information of the crash-log here.

ibmvnic: avoid calling napi_disable() twice
commit 0775ebc upstream. __ibmvnic_open calls napi_disable without checking whether NAPI polling has already been disabled or not. This could cause napi_disable being called twice, which could generate deadlock. For example, the first napi_disable will spin until NAPI_STATE_SCHED is cleared by napi_complete_done, then set it again. When napi_disable is called the second time, it will loop infinitely because no dev->poll will be running to clear NAPI_STATE_SCHED. To prevent above scenario from happening, call ibmvnic_napi_disable() which checks if napi is disabled or not before calling napi_disable.

gro: ensure frag0 meets IP header alignment
commit 38ec494 upstream. After commit 0f6925b ("virtio_net: Do not pull payload in skb->head") Guenter Roeck reported one failure in his tests using sh architecture. After much debugging, we have been able to spot silent unaligned accesses in inet_gro_receive() The issue at hand is that upper networking stacks assume their header is word-aligned. Low level drivers are supposed to reserve NET_IP_ALIGN bytes before the Ethernet header to make that happen. This patch hardens skb_gro_reset_offset() to not allow frag0 fast-path if the fragment is not properly aligned. Some arches like x86, arm64 and powerpc do not care and define NET_IP_ALIGN as 0, this extra check will be a NOP for them. Note that if frag0 is not used, GRO will call pskb_may_pull() as many times as needed to pull network and transport headers.

If these are marked as __init, this causes an oops if a PCI driver is loaded or bound after the kernel has initialised.

arm64: dts: allwinner: Fix SD card CD GPIO for SOPine systems
[ Upstream commit 3dd4ce4 ] Commit 941432d ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. However while both boards indeed have a working CD GPIO on PF6, the polarity is different: the SOPine modules uses a "push-pull" socket, which has an active-high switch, while the Pine64-LTS use the more traditional push-push socket and the common active-low switch. Fix the polarity in the sopine.dtsi, and overwrite it in the LTS board .dts, to make the SD card work again on systems using SOPine modules.

arm64: dts: allwinner: h6: beelink-gs1: Remove ext. 32 kHz osc reference
[ Upstream commit 7a2f6e6 ] Although every Beelink GS1 seems to have external 32768 Hz oscillator, it works only on one from four tested. There are more reports of RTC issues elsewhere, like Armbian forum. One Beelink GS1 owner read RTC osc status register on Android which shipped with the box.

KVM: VMX: Convert vcpu_vmx.exit_reason to a union
[ Upstream commit 8e53324 ] Convert vcpu_vmx.exit_reason from a u32 to a union (of size u32). The full VM_EXIT_REASON field is comprised of a 16-bit basic exit reason in bits 15:0, and single-bit modifiers in bits 31:16. Historically, KVM has only had to worry about handling the "failed VM-Entry" modifier, which could only be set in very specific flows and required dedicated handling. I.e. manually stripping the FAILED_VMENTRY bit was a somewhat viable approach. But even with only a single bit to worry about, KVM has had several bugs related to comparing a basic exit reason against the full exit reason store in vcpu_vmx. Upcoming Intel features, e.g. SGX, will add new modifier bits that can be set on more or less any VM-Exit, as opposed to the significantly more restricted FAILED_VMENTRY, i.e. correctly handling everything in one-off flows isn't scalable. Tracking exit reason in a union forces code to explicitly choose between consuming the full exit reason and the basic exit, and is a convenient way to document and access the modifiers. No functional change intended.

KVM: VMX: Don't use vcpu->run->internal.ndata as an array index
[ Upstream commit 04c4f2e ] __vmx_handle_exit() uses vcpu->run->internal.ndata as an index for an array access. Since vcpu->run is (can be) mapped to a user address space with a writer permission, the 'ndata' could be updated by the user process at anytime (the user process can set it to outside the bounds of the array). So, it is not safe that __vmx_handle_exit() uses the 'ndata' that way.

bpf: Ensure off_reg has no mixed signed bounds for all types
[ Upstream commit 24c109b ] The mixed signed bounds check really belongs into retrieve_ptr_limit() instead of outside of it in adjust_ptr_min_max_vals(). The reason is that this check is not tied to PTR_TO_MAP_VALUE only, but to all pointer types that we handle in retrieve_ptr_limit() and given errors from the latter propagate back to adjust_ptr_min_max_vals() and lead to rejection of the program, it's a better place to reside to avoid anything slipping through for future types. The reason why we must reject such off_reg is that we otherwise would not be able to derive a mask, see details in 9d7ecee ("bpf: restrict unknown scalars of mixed signed bounds for unprivileged").

ARM: 9071/1: uprobes: Don't hook on thumb instructions
commit d2f7eca upstream. Since uprobes is not supported for thumb, check that the thumb bit is not set when matching the uprobes instruction hooks. The Arm UDF instructions used for uprobes triggering (UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the same encoding as a pair of unallocated 32-bit thumb instructions (not UDF) when the condition code is 0b1111 (0xf). This in effect makes it possible to trigger the uprobes functionality from thumb, and at that using two unallocated instructions which are not permanently undefined.

arm64: mte: Ensure TIF_MTE_ASYNC_FAULT is set atomically
commit 2decad9 upstream. The entry from EL0 code checks the TFSRE0_EL1 register for any asynchronous tag check faults in user space and sets the TIF_MTE_ASYNC_FAULT flag. This is not done atomically, potentially racing with another CPU calling set_tsk_thread_flag(). Replace the non-atomic ORR+STR with an STSET instruction. While STSET requires ARMv8.1 and an assembler that understands LSE atomics, the MTE feature is part of ARMv8.5 and already requires an updated assembler.

net: phy: marvell: fix detection of PHY on Topaz switches
commit 1fe976d upstream. Since commit fee2d54 ("net: phy: marvell: mv88e6390 temperature sensor reading"), Linux reports the temperature of Topaz hwmon as constant -75°C. This is because switches from the Topaz family (88E6141 / 88E6341) have the address of the temperature sensor register different from Peridot. This address is instead compatible with 88E1510 PHYs, as was used for Topaz before the above mentioned commit. Create a new mapping table between switch family and PHY ID for families which don't have a model number. And define PHY IDs for Topaz and Peridot families. Create a new PHY ID and a new PHY driver for Topaz's internal PHY. The only difference from Peridot's PHY driver is the HWMON probing method. Prior this change Topaz's internal PHY is detected by kernel as: PHY [...] driver [Marvell 88E6390] (irq=63) And afterwards as: PHY [...] driver [Marvell 88E6341 Family] (irq=63) Signed-off-by: Pali Rohár <pali@kernel.org> BugLink: globalscaletechnologies/linux#1 Fixes: fee2d54 ("net: phy: marvell: mv88e6390 temperature sensor reading") Reviewed-by: Marek Behún <kabel@kernel.org> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
