wifi: iwlwifi: mvm: don't read past the mfuart notifcation

2024-06-21T12:38:13+00:00

[ Upstream commit 4bb95f4535489ed830cf9b34b0a891e384d1aee4 ] In case the firmware sends a notification that claims it has more data than it has, we will read past that was allocated for the notification. Remove the print of the buffer, we won't see it by default. If needed, we can see the content with tracing. This was reported by KFENCE.

wifi: iwlwifi: mvm: check n_ssids before accessing the ssids

2024-06-21T12:38:13+00:00

[ Upstream commit 60d62757df30b74bf397a2847a6db7385c6ee281 ] In some versions of cfg80211, the ssids poinet might be a valid one even though n_ssids is 0. Accessing the pointer in this case will cuase an out-of-bound access. Fix this by checking n_ssids first.

wifi: iwlwifi: dbg_ini: move iwl_dbg_tlv_free outside of debugfs ifdef

[ Upstream commit 87821b67dea87addbc4ab093ba752753b002176a ] The driver should call iwl_dbg_tlv_free even if debugfs is not defined since ini mode does not depend on debugfs ifdef.

[ Upstream commit 0bcc2155983e03c41b21a356af87ae839a6b3ead ] It's dangerous to re-initialize works repeatedly, especially delayed ones that have an associated timer, and even more so if they're not necessarily canceled inbetween. This can be the case for these workers here during FW restart scenarios, so make sure to initialize it only once. While at it, also ensure it is cancelled correctly.
