2022-12-01wifi: rtw89: rfk: rename rtw89_mcc_info to rtw89_rfk_mcc_infoZong-Zhe Yang4-19/+19
The `rtw89_mcc_info mcc` is only for RFK MCC stuffs instead of common MCC management info. Replace it with `rtw89_rfk_mcc_info rfk_mcc` to avoid confusion and reserve `struct rtw89_mcc_info mcc` for MCC management code. (No logic changes.)

2022-12-01wifi: rtw88: 8821c: enable BT device recovery mechanismPing-Ke Shih3-1/+33
8821ce is a combo card, and BT is a USB device that could get card lost during stress test, and need WiFi firmware to detect and recover it, so driver sends a H2C to enable this mechanism.

2022-12-01wifi: rtw89: 8852b: turn off PoP function in monitor modePing-Ke Shih2-0/+9
PoP stands for Packet on Packet that can improve performance in noisy environment, but it could get RX stuck suddenly. In normal mode, firmware can help to resolve the stuck, but firmware doesn't work in monitor mode. Therefore, turn off PoP to avoid RX stuck.

2022-12-01wifi: rtw89: add HE radiotap for monitor modePing-Ke Shih3-1/+41
With basic HE radiotap, we can check data rate in sniffer data. To store the radiotap data, we reserve headroom of aligned 64 bytes, and then update HE radiotap in monitor mode, so it doesn't affect performance in normal mode.

2022-12-01wifi: rtw89: enable mac80211 virtual monitor interfaceZong-Zhe Yang1-0/+6
For running with mac80211 channel context ops and using only as monitor, we need to enable WANT_MONITOR_VIF to let mac80211 process virtual monitor interface. Then, we are able to set channel on the monitor from user space.

2022-12-01wifi: brcmfmac: Check the count value of channel spec to prevent ↵Minsuk Kang1-0/+17
out-of-bounds reads This patch fixes slab-out-of-bounds reads in brcmfmac that occur in brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count value of channel specifications provided by the device is greater than the length of 'list->element[]', decided by the size of the 'list' allocated with kzalloc(). The patch adds checks that make the functions free the buffer and return -EINVAL if that is the case. Note that the negative return is handled by the caller, brcmf_setup_wiphybands() or brcmf_cfg80211_attach(). Found by a modified version of syzkaller.

2022-11-28wifi: iwlwifi: mvm: trigger PCI re-enumeration in case of PLDR syncAvraham Stern7-41/+73
When doing the PLDR flow, the fw goes through a re-read and needs PCI re-enumeration in order to recover. In this case, skip the mac start retry and fw dumps as all the fw and registers are invalid until the PCI re-enumeration. In addition, print the register that shows the re-read counter when loading the fw.

2022-11-28wifi: iwlwifi: mvm: fix double free on tx path.Ben Greear1-1/+11
We see kernel crashes and lockups and KASAN errors related to ax210 firmware crashes. One of the KASAN dumps pointed at the tx path, and it appears there is indeed a way to double-free an skb. If iwl_mvm_tx_skb_sta returns non-zero, then the 'skb' sent into the method will be freed. But, in case where we build TSO skb buffer, the skb may also be freed in error case. So, return 0 in that particular error case and do cleanup manually.

2022-11-28wifi: rtw88: fix race condition when doing H2C commandJi-Pin Jou2-5/+8
For SDIO/USB interface, since the tranferring speed is slower than that in PCIE, it may have race condition when the driver sets down H2C command to the FW. In the function rtw_fw_send_h2c_command, before the patch, box_reg is written first, then box_ex_reg is written. FW starts to work and fetch the value of box_ex_reg, when the most significant byte of box_reg(4 bytes) is written. Meanwhile, for SDIO/USB interface, since the transferring speed is slow, the driver is still in writing the new value of box_ex_reg through the bus, and FW may get the wrong value of box_ex_reg at the moment. To prevent the above driver/FW racing situation, box_ex_reg is written first then box_reg. Furthermore, it is written in 4 bytes at a time, instead of written in one byte one by one. It can increase the speed for SDIO/USB interface.

2022-11-25wifi: ath10k: Store WLAN firmware version in SMEM image tableYoughandhar Chintala2-0/+36
In a SoC based solution, it would be useful to know the versions of the various binary firmware blobs the system is running on. On a QCOM based SoC, this info can be obtained from socinfo debugfs infrastructure. For this to work, respective subsystem drivers have to export the firmware version information to an SMEM based version information table. Having firmware version information at one place will help quickly figure out the firmware versions of various subsystems on the device instead of going through builds/logs in an event of a system crash. Fill WLAN firmware version information in SMEM version table to be printed as part of socinfo debugfs infrastructure on a Qualcomm based SoC. This change is applicable only for SNOC/QMI based targets.

struct brcmf_dload_data_le One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct brcmf_dload_data_le. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

2022-11-18net: ipa: avoid a null pointer dereferenceAlex Elder1-3/+6
Dan Carpenter reported that Smatch found an instance where a pointer which had previously been assumed could be null (as indicated by a null check) was later dereferenced without a similar check. In practice this doesn't lead to a problem because currently the pointers used are all non-null. Nevertheless this patch addresses the reported problem. In addition, I spotted another bug that arose in the same commit. When the command to initialize a routing table memory region was added, the number of entries computed for the non-hashed table was wrong (it ended up being a Boolean rather than the count intended). This bug is fixed here as well.

Xin Long says: ==================== sctp: support vrf processing This patchset adds the VRF processing in SCTP. Simliar to TCP/UDP, it includes socket bind and socket/association lookup changes. For socket bind change, it allows sockets to bind to a VRF device and allows multiple sockets with the same IP and PORT to bind to different interfaces in patch 1-3. For socket/association lookup change, it adds dif and sdif check in both asoc and ep lookup in patch 4 and 5, and when binding to nodev, users can decide if accept the packets received from one l3mdev by setup a sysctl option in patch 6. Note with VRF support, in a netns, an association will be decided by src ip + src port + dst ip + dst port + bound_dev_if, and it's possible for ss to have: State Local Address:Port Peer Address:Port ESTAB 192.168.1.2%vrf-s1:1234 `- ESTAB 192.168.1.2%veth1:1234 192.168.1.1:1234 ESTAB 192.168.1.2%vrf-s2:1234 `- ESTAB 192.168.1.2%veth2:1234 192.168.1.1:1234 See the selftest in patch 7 for more usage. Also, thanks Carlo for testing this patch series on their use. v1->v2: - In Patch 5, move sctp_sk_bound_dev_eq() definition to net/sctp/ input.c to avoid a build error when IP_SCTP is disabled, as Paolo suggested. - In Patch 7, avoid one sleep by disabling the IPv6 dad, and remove another sleep by using ss to check if the server's ready, and also delete two unncessary sleeps in sctp_hello.c, as Paolo suggested. ==================== Signed-off-by: David S.

2022-11-18sctp: add dif and sdif check in asoc and ep lookupXin Long8-61/+89
This patch at first adds a pernet global l3mdev_accept to decide if it accepts the packets from a l3mdev when a SCTP socket doesn't bind to any interface. It's set to 1 to avoid any possible incompatible issue, and in next patch, a sysctl will be introduced to allow to change it. Then similar to inet/udp_sk_bound_dev_eq(), sctp_sk_bound_dev_eq() is added to check either dif or sdif is equal to sk_bound_dev_if, and to check sid is 0 or l3mdev_accept is 1 if sk_bound_dev_if is not set. This function is used to match a association or a endpoint, namely called by sctp_addrs_lookup_transport() and sctp_endpoint_is_match(). All functions that needs updating are: sctp_rcv(): asoc: __sctp_rcv_lookup() __sctp_lookup_association() -> sctp_addrs_lookup_transport() __sctp_rcv_lookup_harder() __sctp_rcv_init_lookup() __sctp_lookup_association() -> sctp_addrs_lookup_transport() __sctp_rcv_walk_lookup() __sctp_rcv_asconf_lookup() __sctp_lookup_association() -> sctp_addrs_lookup_transport() ep: __sctp_rcv_lookup_endpoint() -> sctp_endpoint_is_match() sctp_connect(): sctp_endpoint_is_peeled_off() __sctp_lookup_association() sctp_has_association() sctp_lookup_association() __sctp_lookup_association() -> sctp_addrs_lookup_transport() sctp_diag_dump_one(): sctp_transport_lookup_process() -> sctp_addrs_lookup_transport() Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.
