[ Upstream commit 84ed362 ] Some storage arrays advertise FCP LUNs and NVMe namespaces behind the same WWN.

[ Upstream commit 983f127 ] Current code will send PRLI with FC-NVMe bit set for the targets which support only FCP. This may result into issue with targets which do not understand NVMe and will go into a strange state. This patch would restart the login process by going back to PLOGI state. The PLOGI state will force the target to respond to correct PRLI request.

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.

[ 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.

[ 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.

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.

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.

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.

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.

commit d3a6abc upstream.

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.

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.

[ Upstream commit 2df49d3 ] The attempt to improve performance by changing the PCIe max read request size was added in the vendor driver more than 10 years back and copied to r8169 driver. In the vendor driver this has been removed long ago. Obviously it had no effect, also in my tests I didn't see any difference. Typically the max payload size is less than 512 bytes anyway, and the PCI core takes care that the maximum supported value is set.

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).

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.

[ Upstream commit a51cd6b ] In case when is64 == 1 in emit(A64_REV32(is64, dst, dst), ctx) the generated insn reverses byte order for both high and low 32-bit words, resuling in an incorrect swap as indicated by the jit test: [ 9757.262607] test_bpf: #312 BSWAP 16: 0x0123456789abcdef -> 0xefcd jited:1 8 PASS [ 9757.264435] test_bpf: #313 BSWAP 32: 0x0123456789abcdef -> 0xefcdab89 jited:1 ret 1460850314 != -271733879 (0x5712ce8a != 0xefcdab89)FAIL (1 times) [ 9757.266260] test_bpf: #314 BSWAP 64: 0x0123456789abcdef -> 0x67452301 jited:1 8 PASS [ 9757.268000] test_bpf: #315 BSWAP 64: 0x0123456789abcdef >> 32 -> 0xefcdab89 jited:1 8 PASS [ 9757.269686] test_bpf: #316 BSWAP 16: 0xfedcba9876543210 -> 0x1032 jited:1 8 PASS [ 9757.271380] test_bpf: #317 BSWAP 32: 0xfedcba9876543210 -> 0x10325476 jited:1 ret -1460850316 != 271733878 (0xa8ed3174 != 0x10325476)FAIL (1 times) [ 9757.273022] test_bpf: #318 BSWAP 64: 0xfedcba9876543210 -> 0x98badcfe jited:1 7 PASS [ 9757.274721] test_bpf: #319 BSWAP 64: 0xfedcba9876543210 >> 32 -> 0x10325476 jited:1 9 PASS Fix this by forcing 32bit variant of rev32.
