* hostapd: add a patch that allows processing auth requests for peers in ↵Felix Fietkau2021-11-244-8/+42
| | | | | | | | | | | | | | | | blocked state If authentication fails repeatedly e.g. because of a weak signal, the link can end up in blocked state. If one of the nodes tries to establish a link again before it is unblocked on the other side, it will block the link to that other side. The same happens on the other side when it unblocks the link. In that scenario, the link never recovers on its own. To fix this, allow restarting authentication even if the link is in blocked state, but don't initiate the attempt until the blocked period is over.

* hostapd: fix goto loop for ubus assoc handlerDavid Bauer2021-11-231-5/+5
| | | | | | | | | | When a ubus event handler denies a association with a non-zero return value, the code jumps to preceeding code, creating an endless loop until the event handler accepts the assc request. Move the ubus handler further up the code to avoid creating such a loop. Signed-off-by: David Bauer <mail@david-bauer.net>

* hostapd: fix a race condition on adding AP mode wds sta interfacesFelix Fietkau2021-11-232-3/+25
| | | | | | | | | | | | Both hostapd and netifd attempt to add a VLAN device to a bridge. Depending on which one wins the race, bridge vlan settings might be incomplete, or hostapd might run into an error and refuse to service the client. Fix this by preventing hostapd from adding interfaces to the bridge and instead rely entirely on netifd handling this properly Signed-off-by: Felix Fietkau <nbd@nbd.name> (cherry-picked from commit da4be02fcd5d642954b1c9d9855d9e8d1e6205f4) (cherry-picked from commit 63c01ad025981eaa841353dc0fc27e5017febe21)

| | | | | | | | | | | Since upstream commit 6467de5a8840 ("Randomize z ordinates in scalar mult when timing resistant") WolfSSL requires a RNG for the EC key when built hardened which is the default. Set the RNG for the EC key to fix connections for OWE clients. Signed-off-by: David Bauer <mail@david-bauer.net> (cherry picked from commit ddcb970274c011d3db611ec39350ee4704ff0e02)
* hostapd: P2P: Fix a corner case in peer addition based on PD RequestStefan Lippers-Hollmann2021-03-011-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | p2p_add_device() may remove the oldest entry if there is no room in the peer table for a new peer. This would result in any pointer to that removed entry becoming stale. A corner case with an invalid PD Request frame could result in such a case ending up using (read+write) freed memory. This could only by triggered when the peer table has reached its maximum size and the PD Request frame is received from the P2P Device Address of the oldest remaining entry and the frame has incorrect P2P Device Address in the payload. Fix this by fetching the dev pointer again after having called p2p_add_device() so that the stale pointer cannot be used. This fixes the following security vulnerabilities/bugs: - CVE-2021-27803 - A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests. It could result in denial of service or other impact (potentially execution of arbitrary code), for an attacker within radio range.

* hostapd: backport ignoring 4addr mode enabling errorRaphaël Mélotte2021-02-202-37/+78
| | | | | | | | | | | | | | | | | | | | | This is a backport of the upstream commit 58bbbb598144 ("nl80211: Ignore 4addr mode enabling error if it was already enabled") which fixes same issue as in the current fix contained in '130-wpa_supplicant-multi_ap_roam.patch', but in a different way: nl80211_set_4addr_mode() could fail when trying to enable 4addr mode on an interface that is in a bridge and has 4addr mode already enabled. This operation would not have been necessary in the first place and this failure results in disconnecting, e.g., when roaming from one backhaul BSS to another BSS with Multi AP. Avoid this issue by ignoring the nl80211 command failure in the case where 4addr mode is being enabled while it has already been enabled.

* hostapd: update mesh DFS patches and add mesh HE supportDaniel Golle2020-07-3033-189/+1439
| | | | | | | | | | | | | | | | Drop outdated and by now broken patchset originally supplied by Peter Oh in August 2018 but never merged upstream. Instead add the more promissing rework recently submitted by Markus Theil who picked up Peter's patchset, fixed and completed it and added support for HE (802.11ax) in mesh mode. This is only compile tested and needs some real-life testing.

* hostapd: enter DFS state if no available channel is foundDavid Bauer2020-07-201-0/+37
| | | | | | | | | | | Previously hostapd would not stop transmitting when a DFS event was detected and no available channel to switch to was available. Disable and re-enable the interface to enter DFS state. This way, TX does not happen until the kernel notifies hostapd about the NOP expiring. Signed-off-by: David Bauer <mail@david-bauer.net>
* hostapd: fix compilation of wpa_supplicantKarel Kočí2020-06-181-4/+4
| | | | | | | | | | | | | Ubus patch as it seems have been broken by some rebase in the past as the location of line that adds ubus object file was in condition for CONFIG_MACSEC. That condition was adding object files that are not touched by ubus patch. This means ubus.o does not have to be included in that case. When it has to be and when build fails is when CONFIG_AP is set. All files included in wpa_supplicant that are touched by this patch are in this condition. This means that this is for sure the original place for it. Signed-off-by: Karel Kočí <karel.koci@nic.cz>

* hostapd: bring back mesh patchesDaniel Golle2020-05-2127-107/+791
| | | | | | | | | | | | | Bring back 802.11s mesh features to the level previously available before the recent hostapd version bump. This is mostly to support use of 802.11s on DFS channels, but also making mesh forwarding configurable which is crucial for use of 802.11s MAC with other routing protocols, such as batman-adv, on top. While at it, fix new compiler warning by adapting 700-wifi-reload.patch to upstream changes, now building without any warnings again.

* hostapd: declare struct wpa_bss earlyLeon M. George2019-09-191-0/+19
| | | | | | | | | | | | | | | | wps_supplicant.h assumes that 'struct wpa_bss' is forward declared if CONFIG_WPS is not defined. With the later inclusion of 600-ubus_support, the issue manifests in warnings like these: wps_supplicant.h:113:15: warning: 'struct wpa_bss' declared inside parameter list will not be visible outside of this definition or declaration struct wpa_bss *bss) ^~~~~~~ This patch forward declares 'struct wpa_bss' regardless.

* hostapd: revert signature change in patchLeon M. George2019-09-191-1/+1
| | | | | | | | | | | | The original wpa_hexdump uses a 'void *' for the payload. With patch 410-limit_debug_messages, the signature changes and compiler warnings occur at various places. One such warning is: wpa_debug.h:106:20: note: expected 'const u8 * {aka const unsigned char *}' but argument is of type 'struct wpa_eapol_key *' Signed-off-by: Leon M.

This could result in attacks that would be able to complete EAP-pwd authentication exchange without the attacker having to know the used password. A reflection attack is possible against the EAP-pwd server since the hostapd EAP server did not verify that the EAP-pwd-Commit contains scalar/element values that differ from the ones the server sent out itself. This allows the attacker to complete EAP-pwd authentication without knowing the password, but this does not result in the attacker being able to derive the session key (MSK), i.e., the attacker would not be able to complete the following key exchange (e.g., 4-way handshake in RSN/WPA). An attack using invalid scalar/element values is possible against both the EAP-pwd server and peer since hostapd and wpa_supplicant did not validate these values in the received EAP-pwd-Commit messages. If the used crypto library does not implement additional checks for the element (EC point), this could result in attacks where the attacker could use a specially crafted commit message values to manipulate the exchange to result in deriving a session key value from a very small set of possible values. This could further be used to attack the EAP-pwd server in a practical manner. An attack against the EAP-pwd peer is slightly more complex, but still consider practical. These invalid scalar/element attacks could result in the attacker being able to complete authentication and learn the session key and MSK to allow the key exchange to be completed as well, i.e., the attacker gaining access to the network in case of the attack against the EAP server or the attacker being able to operate a rogue AP in case of the attack against the EAP peer. While similar attacks might be applicable against SAE, it should be noted that the SAE implementation in hostapd and wpa_supplicant does have the validation steps that were missing from the EAP-pwd implementation and as such, these attacks do not apply to the current SAE implementation. Old versions of wpa_supplicant/hostapd did not include the reflection attack check in the SAE implementation, though, since that was added in June 2015 for v2.5 (commit 6a58444d27fd 'SAE: Verify that own/peer commit-scalar and COMMIT-ELEMENT are different'). Vulnerable versions/configurations All hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled in the runtime configuration) are vulnerable against the reflection attack. All wpa_supplicant and hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled in the runtime configuration) are vulnerable against the invalid scalar/element attack when built against a crypto library that does not have an explicit validation step on imported EC points. The following list indicates which cases are vulnerable/not vulnerable: - OpenSSL v1.0.2 or older: vulnerable - OpenSSL v1.1.0 or newer: not vulnerable - BoringSSL with commit 38feb990a183 ('Require that EC points are on the curve.') from September 2015: not vulnerable - BoringSSL without commit 38feb990a183: vulnerable - LibreSSL: vulnerable - wolfssl: vulnerable Acknowledgments Thanks to Mathy Vanhoef (New York University Abu Dhabi) for discovering and reporting the issues and for proposing changes to address them in the implementation.
