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. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

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. Example: cat /sys/kernel/debug/qcom_socinfo/cnss/name QC_IMAGE_VERSION_STRING=WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1 Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1 Signed-off-by:

There are some registers for transmit waveform control, two of them used in this change are for BANDEDGE and TX_SHAPE control. BANDEDGE controls whether to apply band edge filter to transmit waveform. TX_SHAPE controls whether to apply triangular mask to transmit waveform.

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. Reported-by:

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: -

This patch adds 12 small test cases: 01-04 test for the sysctl net.sctp.l3mdev_accept. 05-10 test for only binding to a right l3mdev device, the connection can be created. 11-12 test for two socks binding to different l3mdev devices at the same time, each of them can process the packets from the corresponding peer. The tests run for both IPv4 and IPv6 SCTP. Signed-off-by:

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: -

In sctp_get_port_local(), when binding to IP and PORT, it should also check sk_bound_dev_if to match listening sk if it's set by SO_BINDTOIFINDEX, so that multiple sockets with the same IP and PORT, but different sk_bound_dev_if can be listened at the same time. Signed-off-by:

When binding to an ipv6 address, it calls ipv6_chk_addr() to check if this address is on any dev. If a socket binds to a l3mdev but no dev is passed to do this check, all l3mdev and slaves will be skipped and the check will fail. This patch is to pass the bound_dev to make sure the devices under the same l3mdev can be returned in ipv6_chk_addr(). When the bound_dev is not a l3mdev or l3slave, l3mdev_master_dev_rcu() will return NULL in __ipv6_chk_addr_and_flags(), it will keep compitable with before when NULL dev was passed. Signed-off-by:

After binding to a l3mdev, it should use the route table from the corresponding VRF to verify the addr when binding to an address. Note ipv6 doesn't need it, as binding to ipv6 address does not verify the addr with route lookup. Signed-off-by:

Following 1b16b3fd ("net: phy: mscc: macsec: clear encryption keys when freeing a flow"), go one step further and instead of calling memzero_explicit on the key when freeing a flow, simply not copy the key in the first place as it's only used when a new flow is set up. Signed-off-by:

Alex Elder says: ==================== net: ipa: change GSI firmware load specification Currently, GSI firmware must be loaded for IPA before it can be used--either by the modem, or by the AP. New hardware supports a third option, with the bootloader taking responsibility for loading GSI firmware. In that case, neither the AP nor the modem needs to do that. The first patch in this series deprecates the "modem-init" Device Tree property in the IPA binding, using a new "qcom,gsi-loader" property instead. The second and third implement logic in the code to support either the "old" or the "new" way of specifying how GSI firmware is loaded. The last two patches implement a new value for the "qcom,gsi-loader" property. If the value is "skip", neither the AP nor modem needs to load the GSI firmware. The first of these patches implements the change in the IPA binding; the second implements it in the code. ==================== Link: https://lore.kernel.org/r/20221116073257.34010-1-elder@linaro.orgSigned-off-by:
