2021-09-28ath11k: qmi: avoid error messages when dma allocation failsAaron Ma1-1/+1
qmi tries to allocate a large contiguous dma memory at first, on the AMD Ryzen platform it fails, then retries with small slices. So set flag GFP_NOWARN to avoid flooding dmesg.

2021-09-28ath11k: Replace one-element array with flexible-array memberGustavo A. R. Silva3-7/+4
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. 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]. Refactor the code a bit according to the use of a flexible-array member in struct scan_chan_list_params instead of a one-element array, and use the struct_size() helper. Also, save 25 (too many) bytes that were being allocated: $ pahole -C channel_param drivers/net/wireless/ath/ath11k/reg.o struct channel_param { u8 chan_id; /* 0 1 */ u8 pwr; /* 1 1 */ u32 mhz; /* 2 4 */ /* Bitfield combined with next fields */ u32 half_rate:1; /* 4:16 4 */ u32 quarter_rate:1; /* 4:17 4 */ u32 dfs_set:1; /* 4:18 4 */ u32 dfs_set_cfreq2:1; /* 4:19 4 */ u32 is_chan_passive:1; /* 4:20 4 */ u32 allow_ht:1; /* 4:21 4 */ u32 allow_vht:1; /* 4:22 4 */ u32 allow_he:1; /* 4:23 4 */ u32 set_agile:1; /* 4:24 4 */ u32 psc_channel:1; /* 4:25 4 */ /* XXX 6 bits hole, try to pack */ u32 phy_mode; /* 8 4 */ u32 cfreq1; /* 12 4 */ u32 cfreq2; /* 16 4 */ char maxpower; /* 20 1 */ char minpower; /* 21 1 */ char maxregpower; /* 22 1 */ u8 antennamax; /* 23 1 */ u8 reg_class_id; /* 24 1 */ /* size: 25, cachelines: 1, members: 21 */ /* sum members: 23 */ /* sum bitfield members: 10 bits, bit holes: 1, sum bit holes: 6 bits */ /* last cacheline: 25 bytes */ } __attribute__((__packed__)); as previously, sizeof(struct scan_chan_list_params) was 32 bytes: $ pahole -C scan_chan_list_params drivers/net/wireless/ath/ath11k/reg.o struct scan_chan_list_params { u32 pdev_id; /* 0 4 */ u16 nallchans; /* 4 2 */ struct channel_param ch_param[1]; /* 6 25 */ /* size: 32, cachelines: 1, members: 3 */ /* padding: 1 */ /* last cacheline: 32 bytes */ }; and now with the flexible array transformation it is just 8 bytes: $ pahole -C scan_chan_list_params drivers/net/wireless/ath/ath11k/reg.o struct scan_chan_list_params { u32 pdev_id; /* 0 4 */ u16 nallchans; /* 4 2 */ struct channel_param ch_param[]; /* 6 0 */ /* size: 8, cachelines: 1, members: 3 */ /* padding: 2 */ /* last cacheline: 8 bytes */ }; 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.

In IPQ8074, actual FFT bin size is two bytes but hardware reports it with extra pad size of two bytes for each FFT bin. So finally each FFT bin advertise as four bytes size in the collected data. This FFT pad is not advertised in IPQ6018 platform. To accommodate this different behavior across the platforms, introduce the hw param fft_pad_sz and use it in spectral process. Also group all the spectral params under the new structure in hw param structure for scalable in future.

For 160 MHz, nss_ratio_enabled flag is added to indicate firmware supports sending NSS ratio information from firmware as a part of service ready ext event. Extract this NSS ratio info from service ready ext event and save this information in ath11k_pdev_cap to calculate NSS ratio.

2021-06-22ath11k: Avoid memcpy() over-reading of he_capKees Cook1-4/+10
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring array fields. Since peer_he_cap_{mac,phy}info and he_cap_elem.{mac,phy}_cap_info are not the same sizes, memcpy() was reading beyond field boundaries. Instead, correctly cap the copy length and pad out any difference in size (peer_he_cap_macinfo is 8 bytes whereas mac_cap_info is 6, and peer_he_cap_phyinfo is 12 bytes whereas phy_cap_info is 11).

Currently the fragment cache setup during peer assoc is cleared only during peer delete. In case a key reinstallation happens with the same peer, the same fragment cache with old fragments added before key installation could be clubbed with fragments received after. This might be exploited to mix fragments of different data resulting in a proper unintended reassembled packet to be passed up the stack. Hence flush the fragment cache on every key installation to prevent potential attacks (CVE-2020-24587).
