Add support for userspace to enable/disable the debug ports(ADB,MIPC). - ADB port: /dev/wwan0adb0 - MIPC port: /dev/wwan0mipc0 Application can use ADB (Android Debug Bridge) port to implement functions (shell, pull, push ...) by ADB protocol commands. E.g., ADB commands: - A_OPEN: OPEN(local-id, 0, "destination") - A_WRTE: WRITE(local-id, remote-id, "data") - A_OKEY: READY(local-id, remote-id, "") - A_CLSE: CLOSE(local-id, remote-id, "") Link: https://android.googlesource.com/platform/packages/modules/adb/+/refs/heads/main/README.md Application can use MIPC (Modem Information Process Center) port to debug antenna tuner or noise profiling through this MTK modem diagnostic interface.

2024-11-07virtio_net: Update rss when set queuePhilo Lu
RSS configuration should be updated with queue number. In particular, it should be updated when (1) rss enabled and (2) default rss configuration is used without user modification. During rss command processing, device updates queue_pairs using rss.max_tx_vq. That is, the device updates queue_pairs together with rss, so we can skip the sperate queue_pairs update (VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET below) and return directly. Also remove the `vi->has_rss ?` check when setting vi->rss.max_tx_vq, because this is not used in the other hash_report case. Fixes: c7114b1249fa ("drivers/net/virtio_net: Added basic RSS support.")

2024-11-07virtio_net: Sync rss config to device when virtnet_probePhilo Lu
During virtnet_probe, default rss configuration is initialized, but was not committed to the device. This patch fix this by sending rss command after device ready in virtnet_probe. Otherwise, the actual rss configuration used by device can be different with that read by user from driver, which may confuse the user. If the command committing fails, driver rss will be disabled.

2024-11-07virtio_net: Support dynamic rss indirection table sizePhilo Lu
When reading/writing virtio_net_ctrl_rss, we get the indirection table size from vi->rss_indir_table_size, which is initialized in virtnet_probe(). However, the actual size of indirection_table was set as VIRTIO_NET_RSS_MAX_TABLE_LEN=128. This collision may cause issues if the vi->rss_indir_table_size exceeds 128. This patch instead uses dynamic indirection table, allocated with vi->rss after vi->rss_indir_table_size initialized. And free it in virtnet_remove(). In virtnet_commit_rss_command(), sgs for rss is initialized differently with hash_report. So indirection_table is not used if !vi->has_rss, and then we don't need to alloc indirection_table for hash_report only uses. Fixes: c7114b1249fa ("drivers/net/virtio_net: Added basic RSS support.")

2024-11-07eth: fbnic: Add support to write TCE TCAM entriesMohsin Bashir
Add support to redirect host-to-BMC traffic by writing MACDA entries from the RPC (RX Parser and Classifier) to TCE-TCAM. The TCE TCAM is a small L2 destination TCAM which is placed at the end of the TX path (TCE). Unlike other NICs, where BMC diversion is typically handled by firmware, for fbnic, firmware does not touch anything related to the host; hence, the host uses TCE TCAM to divert BMC traffic. Currently, we lack metadata to track where addresses have been written in the TCAM, except for the last entry written. To address this issue, we start at the opposite end of the table in each pass, so that adding or deleting entries does not affect the availability of all entries, assuming there is no significant reordering of entries.

Commit a23aa0404218 ("net: stmmac: ethtool: Fixed calltrace caused by unbalanced disable_irq_wake calls") introduced checks to prevent unbalanced enable and disable IRQ wake calls. However it only initialized the auxiliary variable on one of the paths, stmmac_request_irq_multi_msi(), missing the other, stmmac_request_irq_single().

2024-11-06wifi: rtlwifi: Drastically reduce the attempts to read efuse in case of failuresGuilherme G. Piccoli
Syzkaller reported a hung task with uevent_show() on stack trace. That specific issue was addressed by another commit [0], but even with that fix applied (for example, running v6.12-rc5) we face another type of hung task that comes from the same reproducer [1]. By investigating that, we could narrow it to the following path: (a) Syzkaller emulates a Realtek USB WiFi adapter using raw-gadget and dummy_hcd infrastructure. (b) During the probe of rtl8192cu, the driver ends-up performing an efuse read procedure (which is related to EEPROM load IIUC), and here lies the issue: the function read_efuse() calls read_efuse_byte() many times, as loop iterations depending on the efuse size (in our example, 512 in total). This procedure for reading efuse bytes relies in a loop that performs an I/O read up to *10k* times in case of failures. We measured the time of the loop inside read_efuse_byte() alone, and in this reproducer (which involves the dummy_hcd emulation layer), it takes 15 seconds each. As a consequence, we have the driver stuck in its probe routine for big time, exposing a stack trace like below if we attempt to reboot the system, for example: task:kworker/0:3 state:D stack:0 pid:662 tgid:662 ppid:2 flags:0x00004000 Workqueue: usb_hub_wq hub_event Call Trace: __schedule+0xe22/0xeb6 schedule_timeout+0xe7/0x132 __wait_for_common+0xb5/0x12e usb_start_wait_urb+0xc5/0x1ef ? usb_alloc_urb+0x95/0xa4 usb_control_msg+0xff/0x184 _usbctrl_vendorreq_sync+0xa0/0x161 _usb_read_sync+0xb3/0xc5 read_efuse_byte+0x13c/0x146 read_efuse+0x351/0x5f0 efuse_read_all_map+0x42/0x52 rtl_efuse_shadow_map_update+0x60/0xef rtl_get_hwinfo+0x5d/0x1c2 rtl92cu_read_eeprom_info+0x10a/0x8d5 ? rtl92c_read_chip_version+0x14f/0x17e rtl_usb_probe+0x323/0x851 usb_probe_interface+0x278/0x34b really_probe+0x202/0x4a4 __driver_probe_device+0x166/0x1b2 driver_probe_device+0x2f/0xd8 [...] We propose hereby to drastically reduce the attempts of doing the I/O reads in case of failures, restricted to USB devices (given that they're inherently slower than PCIe ones). By retrying up to 10 times (instead of 10000), we got reponsiveness in the reproducer, while seems reasonable to believe that there's no sane USB device implementation in the field requiring this amount of retries at every I/O read in order to properly work. Based on that assumption, it'd be good to have it backported to stable but maybe not since driver implementation (the 10k number comes from day 0), perhaps up to 6.x series makes sense.

2024-11-06wifi: rtw88: Enable the new RTL8821AU/RTL8812AU driversBitterblue Smith
These are older Wifi 5 chips. RTL8821AU is 1x1, with or without Bluetooth. RTL8812AU is 2x2, without Bluetooth. Beamforming is not implemented. It looks like these chips need a different implementation than what is in bf.c. Speed tests with RTL8821AU: 137 Mbps download, 144 Mbps upload. Speed tests with RTL8812AU: 344 Mbps download, 387 Mbps upload. Station mode and AP mode were tested. Bluetooth coexistence works. I used my Bluetooth headphones for several days, listening to music and watching videos. There is only a problem with the wifi speeds with one router: With ISP's HG6544C router: Official driver: 3/5 Mbps. rtw88: a bit more, but not steady at all. Not enough to watch a 1080p Youtube video. With my D-Link Eagle R32 router running Openwrt, on the same channel: Official driver: 6/10 Mbps. rtw88: download starts around 30, climbs to 50 / upload is 10 Mbps.
