wifi: iwlwifi: mvm: handle debugfs names more carefully

2024-04-03T13:32:39Z

commit 19d82bdedaf2db0bfb3762dda714ea803065eed5 upstream. With debugfs=off, we can get here with the dbgfs_dir being an ERR_PTR(). Instead of checking for all this, which is often flagged as a mistake, simply handle the names here more carefully by printing them, then we don't need extra checks. Also, while checking, I noticed theoretically 'buf' is too small, so fix that size as well.

wifi: iwlwifi: fw: don't always use FW dump trig

2024-04-03T13:32:39Z

commit 045a5b645dd59929b0e05375f493cde3a0318271 upstream. Since the dump_data (struct iwl_fwrt_dump_data) is a union, it's not safe to unconditionally access and use the 'trig' member, it might be 'desc' instead. Access it only if it's known to be 'trig' rather than 'desc', i.e. if ini-debug is present.

wifi: iwlwifi: mvm: disable MLO for the time being

2024-04-03T13:32:39Z

commit 5f404005055304830bbbee0d66af2964fc48f29e upstream. MLO ended up not really fully stable yet, we want to make sure it works well with the ecosystem before enabling it. Thus, remove the flag, but set WIPHY_FLAG_DISABLE_WEXT so we don't get wireless extensions back until we enable MLO for this hardware.

wifi: rtw88: 8821cu: Fix connection failure

wifi: brcmfmac: cfg80211: Use WSEC to set SAE password

2024-04-03T13:32:28Z

[ Upstream commit 9f7861c56b51b84d30114e7fea9d744a9d5ba9b7 ] Using the WSEC command instead of sae_password seems to be the supported mechanism on newer firmware, and also how the brcmdhd driver does it. The existing firmware mechanism intended for (some) Cypress chips has been separated from the new firmware mechanism using the multi-vendor framework. Depending on the device it will select the appropriate firmware mechanism. This makes WPA3 work with iwd, or with wpa_supplicant pending a support patchset [2].

wifi: brcmfmac: add per-vendor feature detection callback

[ Upstream commit 14e1391b71027948cdbacdbea4bf8858c2068eb7 ] Adding a .feat_attach() callback allowing per-vendor overrides of the driver feature flags. In this patch the callback is only provided by BCA vendor to disable SAE feature as it has not been confirmed yet. BCA chips generally do not have the in-driver supplicant (idsup) feature so they rely on NL80211_CMD_EXTERNAL_AUTH to trigger user-space authentication.

wifi: brcmfmac: Fix use-after-free bug in brcmf_cfg80211_detach

2024-04-03T13:32:00Z

[ Upstream commit 0f7352557a35ab7888bc7831411ec8a3cbe20d78 ] This is the candidate patch of CVE-2023-47233 : https://nvd.nist.gov/vuln/detail/CVE-2023-47233 In brcm80211 driver,it starts with the following invoking chain to start init a timeout worker: ->brcmf_usb_probe ->brcmf_usb_probe_cb ->brcmf_attach ->brcmf_bus_started ->brcmf_cfg80211_attach ->wl_init_priv ->brcmf_init_escan ->INIT_WORK(&cfg->escan_timeout_work, brcmf_cfg80211_escan_timeout_worker); If we disconnect the USB by hotplug, it will call brcmf_usb_disconnect to make cleanup. The invoking chain is : brcmf_usb_disconnect ->brcmf_usb_disconnect_cb ->brcmf_detach ->brcmf_cfg80211_detach ->kfree(cfg); While the timeout woker may still be running. This will cause a use-after-free bug on cfg in brcmf_cfg80211_escan_timeout_worker. Fix it by deleting the timer and canceling the worker in brcmf_cfg80211_detach.
