Hi, I need to disable a feature on 3.13 and 3.14. But I don't have any patch upstream that I can point to as the patch that needs to be backported. We have a feature that is buggy in 3.13 and 3.14. We refactored (and fixed) this feature in 3.15 but the refactor is really not stable material, so basically, I can't backport the fix to 3.13 / 3.14. A user reported that disabling the feature solved (part of) his issues: https://bugzilla.kernel.org/show_bug.cgi?id=72601. OTOH, I don't have any patch in linux.git that could be backported to do what I want in 3.13 / 3.14 - i.e. disable the feature. What is the right process here? I understand that this isn't covered by the "stable rules". So what should I do here? FYI: this is the patch: commit 31e56634bea6ab23817faa069663af3103da0609 Author: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx> Date: Sun May 18 19:05:23 2014 +0300 iwlwifi: mvm: disable beacon filtering This feature has been causing trouble - disable it for now. Fixes are available, but they are too big to be backported. https://bugzilla.kernel.org/show_bug.cgi?id=72601 Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx> diff --git a/drivers/net/wireless/iwlwifi/mvm/mac80211.c b/drivers/net/wireless/iwlwifi/mvm/mac80211.c index cd6ea2e..17c097d 100644 --- a/drivers/net/wireless/iwlwifi/mvm/mac80211.c +++ b/drivers/net/wireless/iwlwifi/mvm/mac80211.c @@ -619,7 +619,7 @@ static int iwl_mvm_mac_add_interface(struct ieee80211_hw *hw, if (ret) goto out_remove_mac; - if (!mvm->bf_allowed_vif && + if (!mvm->bf_allowed_vif && false && vif->type == NL80211_IFTYPE_STATION && !vif->p2p && mvm->fw->ucode_capa.flags & IWL_UCODE_TLV_FLAGS_BF_UPDATED){ mvm->bf_allowed_vif = mvmvif; Emmanuel Grumbach egrumbach@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
