2024-02-16net: ravb: Keep the reverse order of operations in ravb_close()Claudiu Beznea
Keep the reverse order of operations in ravb_close() when compared with ravb_open(). This is the recommended configuration sequence. Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com> Reviewed-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: David S. Miller <davem@davemloft.net>
2024-02-16net: ravb: Get rid of the temporary variable irqClaudiu Beznea
The 4th argument of ravb_setup_irq() is used to save the IRQ number that will be further used by the driver code. Not all ravb_setup_irqs() calls need to save the IRQ number. The previous code used to pass a dummy variable as the 4th argument in case the IRQ is not needed for further usage. That is not necessary as the code from ravb_setup_irq() can detect by itself if the IRQ needs to be saved. Thus, get rid of the code that is not needed.

syzbot reports a memory leak in pppoe_sendmsg [1]. The problem is in the pppoe_recvmsg() function that handles errors in the wrong order. For the skb_recv_datagram() function, check the pointer to skb for NULL first, and then check the 'error' variable, because the skb_recv_datagram() function can set 'error' to -EAGAIN in a loop but return a correct pointer to socket buffer after a number of attempts, though 'error' remains set to -EAGAIN. skb_recv_datagram __skb_recv_datagram // Loop. if (err == -EAGAIN) then // go to the next loop iteration __skb_try_recv_datagram // if (skb != NULL) then return 'skb' // else if a signal is received then // return -EAGAIN Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with Syzkaller.

The buffer_pg variable needs to hold an order-5 allocation (32 x PAGE_SIZE) which, under memory pressure may fail to be allocated. Deal with that error condition properly to avoid doing a NULL pointer de-reference in the subsequent call to dma_map_page(). In addition, the err_reclaim_tx error label in bcmasp_netif_init() needs to ensure that the TX NAPI object is properly deleted, otherwise unregister_netdev() will spin forever attempting to test and clear the NAPI_STATE_HASHED bit.

2024-02-15wifi: ath11k: add support for QCA2066Baochen Qiang
QCA2066 is a PCI based DBS device. It is very similar to WCN6855 overall: they share the same PCI device ID, the same major and minor version numbers, the same register address, and same HAL descriptors etc. The most significant difference is that QCA2066 supports 3-antenna configuration while WCN6855 does not. To differentiate them, subversion numbers are used. Currently four numbers are used by QCA2066: 0x1019A0E1, 0x1019B0E1, 0x1019C0E1 and 0x1019D0E1.

2024-02-15wifi: ath11k: move pci.ops registration aheadBaochen Qiang
In ath11k_pci_probe() there is a switch statement that, based upon the PCI device ID, assigns pci_ops. After the switch, ath11k_pcic_register_pci_ops() is called to register the pci_ops. Unfortunately, this registration is too late if any of the cases in the switch need to perform operations that require the pci_ops to already be registered. In particular, an upcoming patch for QCA2066 needs to call ath11k_pcic_read32(). To address this issue, call ath11k_pcic_register_pci_ops() from each case instead of doing so after the switch. That way the ops will be registered if any subsequent operations within the case processing require the ops to be present.

Provide address list to mac80211 so user doesn't need to specify addresses when a second interface is added because the address can be allocated from the list by mac80211. The derived addresses have LAA (Local Administered Address) bit set, and only the first byte is changed. Take the 00:03:7f:xx:xx:xx as example to derive: addresses[0] is unchanged, it's still 00:03:7f:xx:xx:xx, addresses[1] is 02:03:7f:xx:xx:xx, addresses[2] is 12:03:7f:xx:xx:xx, addresses[3] is 22:03:7f:xx:xx:xx, addresses[4] is 32:03:7f:xx:xx:xx. However as only 3 addresses are reported now, so addresses[3] and addresses[4] aren't actually derived.

2024-02-15wifi: rtlwifi: rtl_usb: Store the endpoint addressesBitterblue Smith
And use the stored addresses in rtl8192cu instead of hardcoding them. This is what the vendor drivers do. Perhaps this is not strictly necessary for RTL8192CU devices. However, the dual mac version of RTL8192DU has two USB interfaces, each with its own set of endpoints. Hardcoding their addresses in the upcoming rtl8192du driver would require making some assumptions which I'm not qualified to make.

2024-02-15wifi: rtlwifi: rtl8192cu: Fix 2T2R chip type detectionBitterblue Smith
rtl8192cu handles 1T1R devices (RTL8188CUS), 1T2R devices (RTL8191CU), and 2T2R devices (RTL8192CU). The 2T2R devices were incorrectly detected as 1T2R because of a mistake in the IS_92C_1T2R macro. The visible effect of this is that the firmware was allowed to use TX rates only up to MCS7. Fix the IS_92C_1T2R macro. Now my 2T2R device has much better upload speed. Before: 46 Mbps. After: 82 Mbps. Also fix a debug message which was printing "RF_1T1R" even for 1T2R chips.

For Wi-Fi 7 chips, FW supports MRC (multi-role concurrent) functions including H2C commands and C2H events. We can consider FW MRC functions as a superset of FW MCC (multi-channel concurrent) functions. And, MRC functions can take MLO things into account. Basically before MLO, SW can also manipulate FW MRC to work original SW MCC flow. So, we add them first and implement the handling in the following.

When unregistering a net device, since the needs_free_netdev has been set to true during registration, the netdevice object is also freed, and as a consequence, the corresponding vif object too, since it is attached to it as private netdevice data. The next occurrence of the loop then tries to access freed vif pointer to the list to move forward in the list. Fix this use-after-free thanks to two mechanisms: - navigate in the list with list_for_each_entry_safe, which allows to safely modify the list as we go through each element. For each element, remove it from the list with list_del_rcu - make sure to wait for RCU grace period end after each vif removal to make sure it is safe to free the corresponding vif too (through unregister_netdev) Since we are in a RCU "modifier" path (not a "reader" path), and because such path is expected not to be concurrent to any other modifier (we are using the vif_mutex lock), we do not need to use RCU list API, that's why we can benefit from list_for_each_entry_safe.
