[PATCH 6.6.y] wifi: mac80211: check basic rates validity in sta_link_apply_parameters

by Hanne-Lotta Mäenpää

From: Mikhail Lobanov <m.lobanov(a)rosa.ru> [ Upstream commit 16ee3ea8faef8ff042acc15867a6c458c573de61 ] When userspace sets supported rates for a new station via NL80211_CMD_NEW_STATION, it might send a list that's empty or contains only invalid values. Currently, we process these values in sta_link_apply_parameters() without checking the result of ieee80211_parse_bitrates(), which can lead to an empty rates bitmap. A similar issue was addressed for NL80211_CMD_SET_BSS in commit ce04abc3fcc6 ("wifi: mac80211: check basic rates validity"). This patch applies the same approach in sta_link_apply_parameters() for NL80211_CMD_NEW_STATION, ensuring there is at least one valid rate by inspecting the result of ieee80211_parse_bitrates(). Found by Linux Verification Center (linuxtesting.org) with Syzkaller. [ Summary of conflict resolutions: - The function ieee80211_parse_bitrates() takes channel width as its first parameter, and the chandef struct has been refactored in kernel version 6.9, in commit 6092077ad09ce880c61735c314060f0bd79ae4aa so that the width is contained in chanreq.oper.width. In kernel version 6.6 the width parameter is defined directly in the chandef struct. ] Fixes: b95eb7f0eee4 ("wifi: cfg80211/mac80211: separate link params from station params") Signed-off-by: Mikhail Lobanov <m.lobanov(a)rosa.ru> Link: https://patch.msgid.link/20250317103139.17625-1-m.lobanov@rosa.ru Signed-off-by: Johannes Berg <johannes.berg(a)intel.com> Signed-off-by: Hanne-Lotta Mäenpää <hannelotta(a)gmail.com> --- net/mac80211/cfg.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/net/mac80211/cfg.c b/net/mac80211/cfg.c index 3ff7f38394a6..1addfba4b285 100644 --- a/net/mac80211/cfg.c +++ b/net/mac80211/cfg.c @@ -1847,12 +1847,12 @@ static int sta_link_apply_parameters(struct ieee80211_local *local, } if (params->supported_rates && - params->supported_rates_len) { - ieee80211_parse_bitrates(link->conf->chandef.width, - sband, params->supported_rates, - params->supported_rates_len, - &link_sta->pub->supp_rates[sband->band]); - } + params->supported_rates_len && + !ieee80211_parse_bitrates(link->conf->chandef.width, + sband, params->supported_rates, + params->supported_rates_len, + &link_sta->pub->supp_rates[sband->band])) + return -EINVAL; if (params->ht_capa) ieee80211_ht_cap_ie_to_sta_ht_cap(sdata, sband, -- 2.50.0

But on the networking side, if MSG_WAITALL is set, or if the socket is of the streaming type and too little was processed, then it will hang on to the buffer rather than recycle or commit it. This is problematic for two reasons: 1) If someone unregisters the provided buffer ring before a later retry, then the req->buf_list will no longer be valid. 2) If multiple sockers are using the same buffer group, then multiple receives can consume the same memory. This can cause data corruption in the application, as either receive could land in the same userspace buffer. Fix this by disallowing partial retries from pinning a provided buffer across multiple executions, if ring provided buffers are used.
