ath5k: fix OOB in ath5k_eeprom_read_pcal_info_5111 The bug was found during fuzzing. Stacktrace locates it in ath5k_eeprom_convert_pcal_info_5111. When none of the curve is selected in the loop, idx can go up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound. pd = &chinfo[pier].pd_curves[idx]; There are many OOB writes using pd later in the code. So I added a sanity check for idx. Checks for other loops involving AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not used outside the loops. The patch is NOT tested with real device. The following is the fuzzing report BUG: KASAN: slab-out-of-bounds in ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] Write of size 1 at addr ffff8880174a4d60 by task modprobe/214 CPU: 0 PID: 214 Comm: modprobe Not tainted 5.6.0 #1 Call Trace: dump_stack+0x76/0xa0 print_address_description.constprop.0+0x16/0x200 ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] __kasan_report.cold+0x37/0x7c ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] kasan_report+0xe/0x20 ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] ? apic_timer_interrupt+0xa/0x20 ? ath5k_eeprom_init_11a_pcal_freq+0xbc0/0xbc0 [ath5k] ? ath5k_pci_eeprom_read+0x228/0x3c0 [ath5k] ath5k_eeprom_init+0x2513/0x6290 [ath5k] ? ath5k_eeprom_init_11a_pcal_freq+0xbc0/0xbc0 [ath5k] ? usleep_range+0xb8/0x100 ? apic_timer_interrupt+0xa/0x20 ? ath5k_eeprom_read_pcal_info_2413+0x2f20/0x2f20 [ath5k] ath5k_hw_init+0xb60/0x1970 [ath5k] ath5k_init_ah+0x6fe/0x2530 [ath5k] ? kasprintf+0xa6/0xe0 ? ath5k_stop+0x140/0x140 [ath5k] ? _dev_notice+0xf6/0xf6 ? apic_timer_interrupt+0xa/0x20 ath5k_pci_probe.cold+0x29a/0x3d6 [ath5k] ? ath5k_pci_eeprom_read+0x3c0/0x3c0 [ath5k] ? mutex_lock+0x89/0xd0 ? ath5k_pci_eeprom_read+0x3c0/0x3c0 [ath5k] local_pci_probe+0xd3/0x160 pci_device_probe+0x23f/0x3e0 ? pci_device_remove+0x280/0x280 ? pci_device_remove+0x280/0x280 really_probe+0x209/0x5d0 Reported-by: Brendan Dolan-Gavitt Signed-off-by: Zekun Shen Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/YckvDdj3mtCkDRIt@a-10-27-26-18.dynapool.vpn.nyu.edu --- drivers/net/wireless/ath/ath5k/eeprom.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/net/wireless/ath/ath5k/eeprom.c b/drivers/net/wireless/ath/ath5k/eeprom.c index 1fbc2c19848f..d444b3d70ba2 100644 --- a/drivers/net/wireless/ath/ath5k/eeprom.c +++ b/drivers/net/wireless/ath/ath5k/eeprom.c @@ -746,6 +746,9 @@ ath5k_eeprom_convert_pcal_info_5111(struct ath5k_hw *ah, int mode, } } + if (idx == AR5K_EEPROM_N_PD_CURVES) + goto err_out; + ee->ee_pd_gains[mode] = 1; pd = &chinfo[pier].pd_curves[idx]; -- cgit v1.2.3 From 67a9d399fcb03177152a8797a855cbd4c995c2de Mon Sep 17 00:00:00 2001 From: Miles Hu Date: Wed, 12 Jan 2022 10:15:10 +0200 Subject: ath11k: enable RX PPDU stats in monitor co-exist mode RX PPDU statistics collection is missing when monitor mode co-exists with other modes.

Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

Before that, we consider architecutre to handle multiple kinds of chipsets. Obviosuly, based on original design, rtw89_core module will have large size even if there is only one chipset under running. It is because all chipset related things are put in rtw89_core now. To reduce such overhead, we extract modules of rtw89 and adjust dependencies between modules. The following assumes that 8852AE, 8852AU, and 8852CE are all supported, we describe the difference before and after extraction. [Before extraction] ------------- |------------------------------------ | rtw89_usb | V ------------- --------------------------------------- ------------- | rtw89_core (including 8852A, 8852C) | <--- | rtw89_pci | --------------------------------------- ------------- The data of 8852A and 8852C are built in rtw89_core. And rtw89_pci is the entry of 8852AE and 8852CE. And rtw89_usb is the entry of 8852AU. [After extraction] ------------- ---------------- |----------- | rtw89_usb | <-------- | rtw89_8852au | | ------------- ---------------- V --------------- | -------------- | | <--------------- | rtw89_core | <--- | rtw89_8852a | -------------- | | <--------------- ^ ^ --------------- | | | ------------- ---------------- | | | | <-------- | rtw89_8852ae | | |----------- | rtw89_pci | ---------------- | | | <----------------- | ------------- | | --------------- ---------------- |--------------- | rtw89_8852c | <------ | rtw89_8852ce | --------------- ---------------- The data of 8852A/8852C is extracted to rtw89_8852a/rtw89_8852c. And rtw89_pci/rtw89_usb handles only common flow of pci/usb bus. Finally, 8852AE, 8852AU, and 8852CE have individual entry modules, i.e. rtw89_8852ae, rtw89_8852au, and rtw89_8852ce correspondingly.

The hardware can support two static BA CAM entries, so I implement a bitmap and a struct to record which entry is used and its corresponding tid. Also, the hardware can learn and create dynamic BA CAM entries automatically if received packets don't match static BA CAM. That means it can still work if we don't use H2C to set static BA CAM. An exception is tid=0 should be always allocated in static BA CAM, so an existing static BA CAM will be replaced if it is full and peer is going to establish a BA with tid=0. The new firmware use new format of this H2C, so I upgrade it as well.

This was first added in commit b0b524f079a2 ("brcmfmac: use ISO3166 country code and 0 rev as fallback"). Subsequently this was reverted in commit 151a7c12c4fc ("Revert "brcmfmac: use ISO3166 country code and 0 rev as fallback""), because it was causing issues with AP mode on some brcmfmac models (specifically on BCM4359/9). Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are all special world-wide compatibility ccode-s. Most of these world-wide ccode-s allow passive scan mode only for 2.4GHz channels 12-14, only enabling them when an AP is seen on them. But at least on brcmfmac43455 devices this is not working correctly, these do not see accesspoints on channels 12-14 unless the ccode is changes to a country where these channels are allowed. Translating received country codes to an ISO3166 country code and 0 rev ccreq fixes devices using a brcmfmac43455 with a X2/XT/XU/XV/ALL ccode not seeing accesspoints on channels 12-14. To avoid this causing issues on other brcmfmac models again, the fallback is limited to only brcmfmac4345* chips this time.

If the nic fails to start, it is possible that the reset_work has already been scheduled. Ensure the work item is canceled so we do not have use-after-free crash in case cleanup is called before the work item is executed. This fixes crash on my x86_64 apu2 when mt7921k radio fails to work. Radio still fails, but OS does not crash.

So we can safely disable the interrupt in mt76s_sdio_irq as soon as possible to increase the CPU productivity by dropping the redundant interrupt triggers. Note that sdio lock acquired/released would be handled in sdio_irq_work at mmc driver so we don't take care in mt76s_sdio_irq at function driver.

Instead, we just need to create one, reuse it across all queues to reduce memory consumption further. And then we should take it into account the actual the host and the device MMC capability to determine what the appropriate xmit_buf_size can be. Both MT7921S and MT7663 can support up to Tx FIFO size of 0x3fe00 which means the device can receive 511 blocks of block size 512 in a row from the host. So if the driver aggregates the frames as many as possible the the device can support, we can merge multiple MMC requests into a single one to get rid of the overhead of the handling and synchronizing in those unnecessary MMC requests and reduce the SDIO lock contention with the Bluetooth concurrent traffic and finally to have the higher bus utilization with less idle cycle. With the patch, it is helpful for WiFi to have steady throughput performance especially while running Bluetooth concurrently.

The current hardware there calculates checksum after the SNAP header, but only RFC 1042 (and some other cases, but replicating the exact hardware logic for corner cases in the driver seemed awkward.) Newer generations of hardware will checksum _including_ the SNAP, which makes things easier. To handle that, simply always assume the checksum _includes_ the SNAP header, which this patch does, requiring to first add it for older iwlwifi hardware, and then remove it again later on conversion. Alternatively, we could have: 1) Always assumed the checksum starts _after_ the SNAP header; the problem with this is that we'd have to replace the exact "what is the SNAP" check in iwlwifi that cfg80211 has. 2) Made it configurable with some flag, but that seemed like too much complexity.

Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.
