2021-01-09mwifiex: Fix possible buffer overflows in mwifiex_cmd_802_11_ad_hoc_startZhang Xiaohui1-0/+2
[ Upstream commit 5c455c5ab332773464d02ba17015acdca198f03d ] mwifiex_cmd_802_11_ad_hoc_start() calls memcpy() without checking the destination size may trigger a buffer overflower, which a local user could use to cause denial of service or the execution of arbitrary code. Fix it by putting the length check before calling memcpy().

2020-12-30ath11k: Fix incorrect tlvs in scan start commandPradeep Kumar Chitrapu1-31/+0
[ Upstream commit f57ad6a9885e8399897daee3249cabccf9c972f8 ] Currently 6G specific tlvs have duplicate entries which is causing scan failures. Fix this by removing the duplicate entries of the same tlv. This also fixes out-of-bound memory writes caused due to adding tlvs when num_hint_bssid and num_hint_s_ssid are ZEROs.

[ Upstream commit 5da7acfec5ec55aa0b69b8760f1d2116b4e2ad26 ] It was observed that the codepath for the ATH11K_SKB_HW_80211_ENCAP was used even when the IEEE80211_TX_CTRL_HW_80211_ENCAP was not enabled for a an skbuff.

2020-12-30ath11k: Don't cast ath11k_skb_cb to ieee80211_tx_info.controlSven Eckelmann3-12/+21
[ Upstream commit f4d291b43f809b74c66b21f5190cd578af43070b ] The driver_data area of ieee80211_tx_info is used in ath11k for ath11k_skb_cb. The first function in the TX patch which rewrites it to ath11k_skb_cb is already ath11k_mac_op_tx. No one else in the code path must use it for something else before it reinitializes it. Otherwise the data has to be considered uninitialized or corrupt. But the ieee80211_tx_info.control shares exactly the same area as ieee80211_tx_info.driver_data and ath11k is still using it. This results in best case in a ath11k c000000.wifi1: no vif found for mgmt frame, flags 0x0 or (slightly worse) in a kernel oops. Instead, the interesting data must be moved first into the ath11k_skb_cb and ieee80211_tx_info.control must then not be used anymore.

2020-12-30ath11k: Fix number of rules in filtered ETSI regdomainSven Eckelmann1-2/+3
[ Upstream commit 6189be7d145c3a2d48514eb8755483602ff5a4b4 ] The ath11k code will try to insert wheather rader related limits when the DFS region is set to ETSI. For this reason, it will add two more entries in the array of reg_rules. But the 2.4.0.1 firmware is prefiltering the list of reg rules it returns for 2.4GHz PHYs. They will then not contain the list of 5GHz rules and thus no wheather radar band rules were inserted by this code. But the code didn't fix the n_reg_rules for this regulatory domain and PHY when this happened. This resulted in a rejection by is_valid_rd because it found rules which start and end at 0khz. This resulted in a splat like: Invalid regulatory domain detected ------------[ cut here ]------------ WARNING: at backports-20200628-4.4.60-9a94b73e75/net/wireless/reg.c:3721 [...] ath11k c000000.wifi1: failed to perform regd update : -22 The number of rules must therefore be saved after they were converted from the ath11k format to the ieee80211_regdomain format and not before.

2020-11-02iwlwifi: pcie: limit memory read spin timeJohannes Berg1-9/+27
When we read device memory, we lock a spinlock, write the address we want to read from the device and then spin in a loop reading the data in 32-bit quantities from another register. As the description makes clear, this is rather inefficient, incurring a PCIe bus transaction for every read. In a typical device today, we want to read 786k SMEM if it crashes, leading to 192k register reads. Occasionally, we've seen the whole loop take over 20 seconds and then triggering the soft lockup detector. Clearly, it is unreasonable to spin here for such extended periods of time. To fix this, break the loop down into an outer and an inner loop, and break out of the inner loop if more than half a second elapsed. To avoid too much overhead, check for that only every 128 reads, though there's no particular reason for that number. Then, unlock and relock to obtain NIC access again, reprogram the start address and continue. This will keep (interrupt) latencies on the CPU down to a reasonable time.

A better check is if the first element of the array is nonzero. In the cases where fw_fifo_addr is initialized by rtw88b and rtw88c, the first array element is 0x780.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: - Add redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs and improving TCP back-pressure. Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain. - Expand netlink policy support and improve policy export to user space. (Ge)netlink core performs request validation according to declared policies. Expand the expressiveness of those policies (min/max length and bitmasks). Allow dumping policies for particular commands. This is used for feature discovery by user space (instead of kernel version parsing or trial and error). - Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. - Allow more than 255 IPv4 multicast interfaces. - Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. - In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. - Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. - Allow more calls to same peer in RxRPC. - Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. - Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. - Add TC actions for implementing MPLS L2 VPNs. - Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. - Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. - Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. - Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. - Support sleepable BPF programs, initially targeting LSM and tracing. - Add bpf_d_path() helper for returning full path for given 'struct path'. - Make bpf_tail_call compatible with bpf-to-bpf calls. - Allow BPF programs to call map_update_elem on sockmaps. - Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). - Support listing and getting information about bpf_links via the bpf syscall. - Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). - Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. - Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). - In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. - Add XDP support for Intel's igb driver. - Support offloading TC flower classification and filtering rules to mscc_ocelot switches. - Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. - Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. - Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. - Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. - Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. - Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. - Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. - Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. - Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete). * tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2583 commits) Revert "bpfilter: Fix build error with CONFIG_BPFILTER_UMH" net, sockmap: Don't call bpf_prog_put() on NULL pointer bpf, selftest: Fix flaky tcp_hdr_options test when adding addr to lo bpf, sockmap: Add locking annotations to iterator netfilter: nftables: allow re-computing sctp CRC-32C in 'payload' statements net: fix pos incrementment in ipv6_route_seq_next net/smc: fix invalid return code in smcd_new_buf_create() net/smc: fix valid DMBE buffer sizes net/smc: fix use-after-free of delayed events bpfilter: Fix build error with CONFIG_BPFILTER_UMH cxgb4/ch_ipsec: Replace the module name to ch_ipsec from chcr net: sched: Fix suspicious RCU usage while accessing tcf_tunnel_info bpf: Fix register equivalence tracking. rxrpc: Fix loss of final ack on shutdown rxrpc: Fix bundle counting for exclusive connections netfilter: restore NF_INET_NUMHOOKS ibmveth: Identify ingress large send packets. ibmveth: Switch order of ibmveth_helper calls. cxgb4: handle 4-tuple PEDIT to NAT mode translation selftests: Add VRF route leaking tests ...
