2024-09-06wifi: cfg80211: skip indicating signal for per-STA profile BSSsVeerendranath Jakkam
Currently signal of the BSS entry generated from the per-STA profile indicated as zero, but userspace may consider it as high signal strength since 0 dBm is a valid RSSI value. To avoid this don't report the signal to userspace when the BSS entry created from a per-STA profile.

2024-09-06wifi: cfg80211: fix UBSAN noise in cfg80211_wext_siwscan()Dmitry Antipov
Looking at https://syzkaller.appspot.com/bug?extid=1a3986bbd3169c307819 and running reproducer with CONFIG_UBSAN_BOUNDS, I've noticed the following: [ T4985] UBSAN: array-index-out-of-bounds in net/wireless/scan.c:3479:25 [ T4985] index 164 is out of range for type 'struct ieee80211_channel *[]' <...skipped...> [ T4985] Call Trace: [ T4985] <TASK> [ T4985] dump_stack_lvl+0x1c2/0x2a0 [ T4985] ? __pfx_dump_stack_lvl+0x10/0x10 [ T4985] ? __pfx__printk+0x10/0x10 [ T4985] __ubsan_handle_out_of_bounds+0x127/0x150 [ T4985] cfg80211_wext_siwscan+0x11a4/0x1260 <...the rest is not too useful...> Even if we do 'creq->n_channels = n_channels' before 'creq->ssids = (void *)&creq->channels[n_channels]', UBSAN treats the latter as off-by-one error. Fix this by using pointer arithmetic rather than an expression with explicit array indexing and use convenient 'struct_size()' to simplify the math here and in 'kzalloc()' above.

2024-09-06dm-integrity: fix a race condition when accessing recalc_sectorMikulas Patocka
There's a race condition when accessing the variable ic->sb->recalc_sector. The function integrity_recalc writes to this variable when it makes some progress and the function dm_integrity_map_continue may read this variable concurrently. One problem is that on 32-bit architectures the 64-bit variable is not read and written atomically - it may be possible to read garbage if read races with write. Another problem is that memory accesses to this variable are not guarded with memory barriers. This commit fixes the race - it moves reading ic->sb->recalc_sector to an earlier place where we hold &ic->endio_wait.lock.

Implement .ndo_start_xmit function to fill the information of the packet to be transmitted into the tx descriptor, and then the hardware will transmit the packet using the information in the tx descriptor. In addition, we also implemented the tx_handler function to enable the tx descriptor to be reused.

2024-09-05rtase: Implement hardware configuration functionJustin Lai
Implement rtase_hw_config to set default hardware settings, including setting interrupt mitigation, tx/rx DMA burst, interframe gap time, rx packet filter, near fifo threshold and fill descriptor ring and tally counter address, and enable flow control. When filling the rx descriptor ring, the first group of queues needs to be processed separately because the positions of the first group of queues are not regular with other subsequent groups. The other queues are all newly added features, but we want to retain the original design. So they were not put together.

2024-09-05rtase: Implement the interrupt routine and rtase_pollJustin Lai
1. Implement rtase_interrupt to handle txQ0/rxQ0, txQ4~txQ7 interrupts, and implement rtase_q_interrupt to handle txQ1/rxQ1, txQ2/rxQ2 and txQ3/rxQ3 interrupts. 2. Implement rtase_poll to call ring_handler to process the tx or rx packet of each ring. If the returned value is budget,it means that there is still work of a certain ring that has not yet been completed.

2024-09-05rtase: Implement the .ndo_open functionJustin Lai
Implement the .ndo_open function to set default hardware settings and initialize the descriptor ring and interrupts. Among them, when requesting interrupt, because the first group of interrupts needs to process more events, the overall structure and interrupt handler will be different from other groups of interrupts, so it needs to be handled separately. The first set of interrupt handlers need to handle the interrupt status of RXQ0 and TXQ0, TXQ4~7, while other groups of interrupt handlers will handle the interrupt status of RXQ1&TXQ1 or RXQ2&TXQ2 or RXQ3&TXQ3 according to the interrupt vector.
