The driver can feed the firmware with previous knowledge that was kept in the driver, but the firmware may still not update its internal tables. This happens when we start a BSS interface, and then the firmware can change the regulatory tables based on our location and it'll use more lenient, location specific rules. Then, if the firmware is shut down (when the interface is brought down), and then an AP interface is created, the firmware will forget the country specific rules. The host will think that we are in a certain country that may allow channels and will try to teach the firmware about our location, but the firmware may still not allow to drop the world wide limitations and apply country specific rules because it was just re-started. In this case, the firmware will reply with MCC_RESP_ILLEGAL to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let the upper layers (cfg80211 / hostapd) know that the channel list they know about has been updated.

[PATCH 4.14] kbuild: allow to use GCC toolchain not in Clang search path

by Nathan Chancellor

From: Stefan Agner <stefan(a)agner.ch> commit ef8c4ed9db80261f397f0c0bf723684601ae3b52 upstream. When using a GCC cross toolchain which is not in a compiled in Clang search path, Clang reverts to the system assembler and linker. This leads to assembler or linker errors, depending on which tool is first used for a given architecture. It seems that Clang is not searching $PATH for a matching assembler or linker. Make sure that Clang picks up the correct assembler or linker by passing the cross compilers bin directory as search path. This allows to use Clang provided by distributions with GCC toolchains not in /usr/bin.

I think it's fine to apply it only to 4.19 and 4.14. It's not imperative that the older kernels get it. People building those kernels should already have their tools in place; it's not like we expect *new* users of ancient kernels, who will be tripped up by this.

[PATCH v2] Return only active connectors for get_resources ioctl

by Stanislav Lisovskiy

Currently kernel might allocate different connector ids for the same outputs in case of DP MST, which seems to confuse userspace. There are can be different connector ids in the list, which could be assigned to the same output, while being in different states. This results in issues, like external displays staying blank after quick unplugging and plugging back(bug #106250). Returning only active DP connectors fixes the issue. v2: Removed caps from the title Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106250 Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy(a)intel.com> --- drivers/gpu/drm/drm_mode_config.c | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/drm_mode_config.c b/drivers/gpu/drm/drm_mode_config.c index ee80788f2c40..ec5b2b08a45e 100644 --- a/drivers/gpu/drm/drm_mode_config.c +++ b/drivers/gpu/drm/drm_mode_config.c @@ -143,6 +143,7 @@ int drm_mode_getresources(struct drm_device *dev, void *data, drm_connector_list_iter_begin(dev, &conn_iter); count = 0; connector_id = u64_to_user_ptr(card_res->connector_id_ptr); + DRM_DEBUG_KMS("GetResources: writing connectors start"); drm_for_each_connector_iter(connector, &conn_iter) { /* only expose writeback connectors if userspace understands them */ if (!file_priv->writeback_connectors && @@ -150,15 +151,20 @@ int drm_mode_getresources(struct drm_device *dev, void *data, continue; if (drm_lease_held(file_priv, connector->base.id)) { - if (count < card_res->count_connectors && - put_user(connector->base.id, connector_id + count)) { - drm_connector_list_iter_end(&conn_iter); - return -EFAULT; + if (connector->connector_type != DRM_MODE_CONNECTOR_DisplayPort || + connector->status != connector_status_disconnected) { + if (count < card_res->count_connectors && + put_user(connector->base.id, connector_id + count)) { + drm_connector_list_iter_end(&conn_iter); + return -EFAULT; + } + DRM_DEBUG_KMS("GetResources: connector %s", connector->name); + count++; } - count++; } } card_res->count_connectors = count; + DRM_DEBUG_KMS("GetResources: writing connectors end - count %d", count); drm_connector_list_iter_end(&conn_iter); return ret; -- 2.17.1
