2019-11-06rtlwifi: Fix potential overflow on P2P codeLaura Abbott1-0/+6
commit 8c55dedb795be8ec0cf488f98c03a1c2176f7fb1 upstream. Nicolas Waisman noticed that even though noa_len is checked for a compatible length it's still possible to overrun the buffers of p2pinfo since there's no check on the upper bound of noa_num. Bound noa_num against P2P_MAX_NOA_NUM.

2019-11-06rtlwifi: rtl_pci: Fix problem of too small skb->lenLarry Finger1-1/+2
commit b43f4a169f220e459edf3ea8f8cd3ec4ae7fa82d upstream. In commit 8020919a9b99 ("mac80211: Properly handle SKB with radiotap only"), buffers whose length is too short cause a WARN_ON(1) to be executed. This change exposed a fault in rtlwifi drivers, which is fixed by regarding packets with skb->len <= FCS_LEN as though they are in error and dropping them. The test is now annotated as likely.

commit 29b68a920f6abb7b5ba21ab4b779f62d536bac9b upstream. Since each skb in RX ring is reused instead of new allocation, we can treat the DMA in a more efficient way by DMA synchronization.

2019-10-05rtw88: pci: Rearrange the memory usage for skb in RX ISRJian-Hong Pan1-27/+22
commit ee6db78f5db9bfe426c57a1ec9713827ebccd2d4 upstream. Testing with RTL8822BE hardware, when available memory is low, we frequently see a kernel panic and system freeze. First, rtw_pci_rx_isr encounters a memory allocation failure (trimmed): rx routine starvation WARNING: CPU: 7 PID: 9871 at drivers/net/wireless/realtek/rtw88/pci.c:822 rtw_pci_rx_isr.constprop.25+0x35a/0x370 [rtwpci] [ 2356.580313] RIP: 0010:rtw_pci_rx_isr.constprop.25+0x35a/0x370 [rtwpci] Then we see a variety of different error conditions and kernel panics, such as this one (trimmed): rtw_pci 0000:02:00.0: pci bus timeout, check dma status skbuff: skb_over_panic: text:00000000091b6e66 len:415 put:415 head:00000000d2880c6f data:000000007a02b1ea tail:0x1df end:0xc0 dev:<NULL> ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:105! invalid opcode: 0000 [#1] SMP NOPTI RIP: 0010:skb_panic+0x43/0x45 When skb allocation fails and the "rx routine starvation" is hit, the function returns immediately without updating the RX ring. At this point, the RX ring may continue referencing an old skb which was already handed off to ieee80211_rx_irqsafe(). When it comes to be used again, bad things happen. This patch allocates a new, data-sized skb first in RX ISR. After copying the data in, we pass it to the upper layers. However, if skb allocation fails, we effectively drop the frame. In both cases, the original, full size ring skb is reused. In addition, to fixing the kernel crash, the RX routine should now generally behave better under low memory conditions.

2019-07-12scripts/spelling.txt: drop "sepc" from the misspelling listPaul Walmsley1-1/+1
The RISC-V architecture has a register named the "Supervisor Exception Program Counter", or "sepc". This abbreviation triggers checkpatch.pl's misspelling detector, resulting in noise in the checkpatch output. The risk that this noise could cause more useful warnings to be missed seems to outweigh the harm of an occasional misspelling of "spec". Thus drop the "sepc" entry from the misspelling list.

Support more regulatory domains including IC, KCC, ACMA, CHILE, UKRAINE, and MEXICO. Corresponding tx power limits for these regulatory domains are added in tx power limit table. Besides, tx power limits in some case are also updated to follow RF v20 for better tx power indexes. Channel plan mapping table are upgraded to consider more 2G and 5G channel plans combination cases. It allow us to identify different situations more accuratly by channel plan IDs. In addition, mapping table for country code and channel plan ID and mapping table for country code and tx power limit are also updated to follow RF v20.

2019-06-25rtw88: 8822c: add rf write protection when switching channelChien-Hsun Liao1-4/+9
Collision of writing rf registers could occur if the driver writes rf registers by direct write while the hardware is writing other rf registers by pi write simultaneously. Hardware pi write can be triggered by rf calibrations sometimes, so the driver can not always write rf registers by direct write protection. Direct write protection can make sure that there is no hardware pi write during the direct write. According to some experiments, if we add direct write protection when switching channel, the performance of rf calibration will not be affected.

2019-05-28rtlwifi: rtl8821ae: Convert inline routines to little-endian wordsLarry Finger3-179/+185
In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. The macro that cleared a descriptor has now been converted into an inline routine.

2019-05-28rtlwifi: rtl8821ae: Convert macros that set descriptorLarry Finger3-275/+474
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed later. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-05-28rtlwifi: rtl8821ae: Replace local bit manipulation macrosLarry Finger2-126/+127
This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-05-28rtlwifi: 8192de: Fix used uninitialized variables in power trackingPing-Ke Shih1-2/+9
ofdm_index_old[] is the index of ofdmswing_table[], and used to indicate initial value of ROFDM0_X{A,B}TXIQIMBALANCE in rtl8192de_phy_reg_2tarray[] table, and the initial value is corresponding to calibration thermal value written in efuse, namely rtlefuse->eeprom_thermalmeter. Then, local variable ofdm_index_old[] save to rtlpriv->dm.ofdm_index[] for operational use. If thermal value (temperature) is increasing, output TX power is lower. So, we calculate the delta between current and calibration thermal value, then add power to yield expected and the same output TX power. Thus, ofdm_index[] should be initialized as rtlpriv->dm.ofdm_index[], and shift to proper index depends on delta of thermal value. Then, new power value ofdmswing_table[ofdm_index[]] is written to register.
