2020-03-20mac80211: handle no-preauth flag for control portMarkus Theil1-0/+3
This patch adds support for disabling pre-auth rx over the nl80211 control port for mac80211.

2020-03-20nl80211: add no pre-auth attribute and ext. feature flag for ctrl. portMarkus Theil1-0/+1
If the nl80211 control port is used before this patch, pre-auth frames (0x88c7) are send to userspace uncoditionally. While this enables userspace to only use nl80211 on the station side, it is not always useful for APs. Furthermore, pre-auth frames are ordinary data frames and not related to the control port. Therefore it should for example be possible for pre-auth frames to be bridged onto a wired network on AP side without touching userspace. For backwards compatibility to code already using pre-auth over nl80211, this patch adds a feature flag to disable this behavior, while it remains enabled by default. An additional ext. feature flag is added to detect this from userspace. Thanks to Jouni for pointing out, that pre-auth frames should be handled as ordinary data frames.

2020-02-07nl80211: add src and dst addr attributes for control port tx/rxMarkus Theil3-17/+36
When using control port over nl80211 in AP mode with pre-authentication, APs need to forward frames to other APs defined by their MAC address. Before this patch, pre-auth frames reaching user space over nl80211 control port have no longer any information about the dest attached, which can be used for forwarding to a controller or injecting the frame back to a ethernet interface over a AF_PACKET socket. Analog problems exist, when forwarding pre-auth frames from AP -> STA. This patch therefore adds the NL80211_ATTR_DST_MAC and NL80211_ATTR_SRC_MAC attributes to provide more context information when forwarding. The respective arguments are optional on tx and included on rx. Therefore unaware existing software is not affected. Software which wants to detect this feature, can do so by checking against: NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211_MAC_ADDRS Signed-off-by: Markus Theil <markus.theil@tu-ilmenau.de> Link: https://lore.kernel.org/r/20200115125522.3755-1-markus.theil@tu-ilmenau.de [split into separate cfg80211/mac80211 patches] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2020-02-07cfg80211/mac80211: Allow user space to register for station Rx authenticationIlan Peer3-7/+33
To support Pre Association Security Negotiation (PASN) while already associated to one AP, allow user space to register to Rx authentication frames, so that the user space logic would be able to receive/handle authentication frames from a different AP as part of PASN. Note that it is expected that user space would intelligently register for Rx authentication frames, i.e., only when PASN is used and configure a match filter only for PASN authentication algorithm, as otherwise the MLME functionality of mac80211 would be broken. Additionally, since some versions of the user space daemons wrongly register to all types of authentication frames (which might result in unexpected behavior) allow such registration if the request is for a specific authentication algorithm number.

Commit ab4dfa20534e ("cfg80211: Allow drivers to advertise supported AKM suites") introduces the support to advertize supported AKMs to userspace. This needs an enhancement to advertize the AKM support per interface type, specifically for the cfg80211-based drivers that implement SME and use different mechanisms to support the AKM's for each interface type (e.g., the support for SAE, OWE AKM's take different paths for such drivers on STA/AP mode). This commit aims the same and enhances the earlier mechanism of advertizing the AKMs per wiphy. Add new nl80211 attributes and data structure to provide supported AKMs per interface type to userspace. the AKMs advertized in akm_suites are default capabilities if not advertized for a specific interface type in iftype_akm_suites.

2020-01-15wireless: wext: avoid gcc -O3 warningArnd Bergmann1-1/+2
After the introduction of CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3, the wext code produces a bogus warning: In function 'iw_handler_get_iwstats', inlined from 'ioctl_standard_call' at net/wireless/wext-core.c:1015:9, inlined from 'wireless_process_ioctl' at net/wireless/wext-core.c:935:10, inlined from 'wext_ioctl_dispatch.part.8' at net/wireless/wext-core.c:986:8, inlined from 'wext_handle_ioctl': net/wireless/wext-core.c:671:3: error: argument 1 null where non-null expected [-Werror=nonnull] memcpy(extra, stats, sizeof(struct iw_statistics)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from arch/x86/include/asm/string.h:5, net/wireless/wext-core.c: In function 'wext_handle_ioctl': arch/x86/include/asm/string_64.h:14:14: note: in a call to function 'memcpy' declared here The problem is that ioctl_standard_call() sometimes calls the handler with a NULL argument that would cause a problem for iw_handler_get_iwstats. However, iw_handler_get_iwstats never actually gets called that way. Marking that function as noinline avoids the warning and leads to slightly smaller object code as well.

2020-01-15cfg80211: Fix radar event during another phy CACOrr Mazor3-1/+37
In case a radar event of CAC_FINISHED or RADAR_DETECTED happens during another phy is during CAC we might need to cancel that CAC. If we got a radar in a channel that another phy is now doing CAC on then the CAC should be canceled there. If, for example, 2 phys doing CAC on the same channels, or on comptable channels, once on of them will finish his CAC the other might need to cancel his CAC, since it is no longer relevant. To fix that the commit adds an callback and implement it in mac80211 to end CAC. This commit also adds a call to said callback if after a radar event we see the CAC is no longer relevant Signed-off-by: Orr Mazor <Orr.Mazor@tandemg.com> Reviewed-by: Sergey Matyukevich <sergey.matyukevich.os@quantenna.com> Link: https://lore.kernel.org/r/20191222145449.15792-1-Orr.Mazor@tandemg.com [slightly reformat/reword commit message] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

If wdev->wext.keys was initialized it didn't get reset to NULL on unregister (and it doesn't get set in cfg80211_init_wdev either), but wdev is reused if unregister was triggered through cfg80211_switch_netns. The next unregister (for whatever reason) will try to free wdev->wext.keys again.

Function nl80211_validate_nested() is not specific to nl80211, it's a counterpart to nla_validate_nested_deprecated() with strict validation. For consistency with other validation and parse functions, rename it to nla_validate_nested().

2019-11-27ftrace: Rework event_create_dir()Peter Zijlstra1-3/+3
Rework event_create_dir() to use an array of static data instead of function pointers where possible. The problem is that it would call the function pointer on module load before parse_args(), possibly even before jump_labels were initialized. Luckily the generated functions don't use jump_labels but it still seems fragile. It also gets in the way of changing when we make the module map executable. The generated function are basically calling trace_define_field() with a bunch of static arguments. So instead of a function, capture these arguments in a static array, avoiding the function call. Now there are a number of cases where the fields are dynamic (syscall arguments, kprobes and uprobes), in which case a static array does not work, for these we preserve the function call. Luckily all these cases are not related to modules and so we can retain the function call for them. Also fix up all broken tracepoint definitions that now generate a compile error.

2019-11-08cfg80211: VLAN offload support for set_key and set_sta_vlanGurumoorthi Gnanasambandhan1-0/+11
This provides an alternative mechanism for AP VLAN support where a single netdev is used with VLAN tagged frames instead of separate netdevs for each VLAN without tagged frames from the WLAN driver. By setting NL80211_EXT_FEATURE_VLAN_OFFLOAD flag the driver indicates support for a single netdev with VLAN tagged frames. Separate VLAN-specific netdevs can be added using RTM_NEWLINK/IFLA_VLAN_ID similarly to Ethernet. NL80211_CMD_NEW_KEY (for group keys), NL80211_CMD_NEW_STATION, and NL80211_CMD_SET_STATION will optionally specify vlan_id using NL80211_ATTR_VLAN_ID.
