hostapd: Add cell_density data rates option Add a cell_density option to configure data rates for normal, high and very high cell density wireless deployments. The purpose of using a minimum basic/mandatory data rate that is higher than 6 Mb/s, or 5.5 Mb/s (802.11b compatible), in high cell density environments is to transmit broadcast/multicast data frames using less airtime or to reduce management overheads where significant co-channel interference (CCI) exists and cannot be avoided. Caution: Without careful design and validation, configuration of a too high minimum basic/mandatory data rate can sacrifice connection stability or disrupt the ability to reliably connect and authenticate for little to no capacity benefit. This is because this configuration affects the ability of clients to hear and demodulate management, control and broadcast/multicast data frames. Deployments that have not been specifically designed and validated are usually best suited to use 6, 12 and 24 Mb/s as basic/mandatory data rates. Only usually seek to configure a 12 Mb/s, or 11 Mb/s (802.11b compatible), minimum basic/mandatory rate in high cell density deployments that have been designed and validated for this. For many deployments, the minimum basic/mandatory data rate should not be configured above 12 Mb/s to 18 Mb/s, 24 Mb/s or higher. Such a configuration is only appropriate for use in very high cell density deployment scenarios. A cell_density of Very High (3) should only be used where a deployment has a valid use case and has been designed and validated specifically for this use, nearly always with highly directional antennas - an example would be stadium deployments. For example, with a 24 Mb/s OFDM minimum basic/mandatory data rate, approximately a -73 dBm RSSI is required to decode frames. Many clients will not have roamed elsewhere by the time that they experience -73 dBm and, where they do, they frequently may not hear and be able to demodulate beacon, control or broadcast/multicast data frames causing connectivity issues. There is a myth that disabling lower basic/mandatory data rates will improve roaming and avoid sticky clients. For 802.11n, 802.11ac and 802.11ax clients this is not correct as clients will shift to and use lower MCS rates and not to the 802.11b or 802.11g/802.11a rates that are able to be used as basic/mandatory data rates. There is a myth that disabling lower basic/mandatory data rates will ensure that clients only use higher data rates and that better performance is assured. For 802.11n, 802.11ac and 802.11ax clients this is not correct as clients will shift around and use MCS rates and not the 802.11b or 802.11g/802.11a rates that able to be used as basic/mandatory data rates. Cell Density 0 - Disabled (Default) Setting cell_density to 0 does not configure data rates. This is the default. 1 - Normal Cell Density Setting cell_density to 1 configures the basic/mandatory rates to 6, 12 and 24 Mb/s OFDM rates where legacy_rates is 0. Supported rates lower than the minimum basic/mandatory rate are not offered. Setting cell_density to 1 configures the basic/mandatory rates to the 5.5 and 11 Mb/s DSSS rates where legacy_rates is 1. Supported rates lower than the minimum basic/mandatory rate are not offered. 2 - High Cell Density Setting the cell_density to 2 configures the basic/mandatory rates to the 12 and 24 Mb/s OFDM rates where legacy_rates is 0. Supported rates lower than the minimum basic/mandatory rate are not offered. Setting the cell_density to 2 configures the basic/mandatory rates to the 11 Mb/s DSSS rate where legacy_rates is 1. Supported rates lower than the minimum basic/mandatory rate are not offered. 3 - Very High Cell Density Setting the cell_density to 3 configures the basic/mandatory rates to the 24 Mb/s OFDM rate where legacy_rates is 0. Supported rates lower than the minimum basic/mandatory rate are not offered. Setting the cell_density to 3 only has effect where legacy_rates is 0, else this has the same effect as being configured with a cell_density of 2. Where specified, the basic_rate and supported_rates options continue to override both the cell_density and legacy_rates options. Signed-off-by: Nick Lowe <nick.lowe@gmail.com>

hostapd: add support for subject validation The wpa_supplicant supports certificate subject validation via the subject match(2) and altsubject_match(2) fields. domain_match(2) and domain_suffix_match(2) fields are also supported for advanced matches. This validation is especially important when connecting to access points that use PAP as the Phase 2 authentication type. Without proper validation, the user's password can be transmitted to a rogue access point in plaintext without the user's knowledge. Most organizations already require these attributes to be included to ensure that the connection from the STA and the AP is secure. Includes LuCI changes via openwrt/luci#3444. From the documentation: subject_match - Constraint for server certificate subject. This substring is matched against the subject of the authentication server certificate. If this string is set, the server sertificate is only accepted if it contains this string in the subject. The subject string is in following format: /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as .example.com subject_match2 - Constraint for server certificate subject. This field is like subject_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. altsubject_match - Constraint for server certificate alt. subject. Semicolon separated string of entries to be matched against the alternative subject name of the authentication server certificate. If this string is set, the server sertificate is only accepted if it contains one of the entries in an alternative subject name extension. altSubjectName string is in following format: TYPE:VALUE Example: EMAIL:server@example.com Example: DNS:server.example.com;DNS:server2.example.com Following types are supported: EMAIL, DNS, URI altsubject_match2 - Constraint for server certificate alt. subject. This field is like altsubject_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_match - Constraint for server domain name. If set, this FQDN is used as a full match requirement for the server certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met. If no dNSName values are present, this constraint is matched against SubjectName CN using same full match comparison. This behavior is similar to domain_suffix_match, but has the requirement of a full match, i.e., no subdomains or wildcard matches are allowed. Case-insensitive comparison is used, so "Example.com" matches "example.com", but would not match "test.Example.com". More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed together. domain_match2 - Constraint for server domain name. This field is like domain_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_suffix_match - Constraint for server domain name. If set, this FQDN is used as a suffix match requirement for the AAA server certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met. If no dNSName values are present, this constraint is matched against SubjectName CN using same suffix match comparison. Suffix match here means that the host/domain name is compared one label at a time starting from the top-level domain and all the labels in domain_suffix_match shall be included in the certificate. The certificate may include additional sub-level labels in addition to the required labels. More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed together. For example, domain_suffix_match=example.com would match test.example.com but would not match test-example.com. This field is like domain_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_suffix_match2 - Constraint for server domain name. This field is like domain_suffix_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. Signed-off-by: David Lam <david@thedavid.net>

hostapd: backport BSSID black/whitelists This change adds the configuration options "bssid_whitelist" and "bssid_blacklist" used to limit the AP selection of a network to a specified (finite) set or discard certain APs. This can be useful for environments where multiple networks operate using the same SSID and roaming between those is not desired. It is also useful to ignore a faulty or otherwise unwanted AP. In many applications it is useful not just to enumerate a group of well known access points, but to use a address/mask notation to match an entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00). This is especially useful if an OpenWrt device with two radios is used to retransmit the same network (one in AP mode for other clients, one as STA for the uplink); the following configuration prevents the device from associating with itself, given that the own AP to be avoided is using the bssid 'C0:FF:EE:D0:0D:42': config wifi-iface option device 'radio2' option network 'uplink' option mode 'sta' option ssid 'MyNetwork' option encryption 'none' list bssid_blacklist 'C0:FF:EE:D0:0D:42/00:FF:FF:FF:FF:FF' This change consists of the following cherry-picked upstream commits: b3d6a0a8259002448a29f14855d58fe0a624ab76 b83e455451a875ba233b3b8ac29aff8b62f064f2 79cd993a623e101952b81fa6a29c674cd858504f (squashed to implement bssid_{white,black}lists) 0047306bc9ab7d46e8cc22ff9a3e876c47626473 (Add os_snprintf_error() helper) Signed-off-by: Stefan Tomanek <stefan.tomanek+openwrt@wertarbyte.de> SVN-Revision: 44438

hostapd: Use EAPOLv1 (802.1X-2001) if WPA enabled Currently, EAPOLv2 (802.1X-2004) is used by default for legacy clients that are not WPA2 (RSN) capable. These legacy clients are often intolerant to this EAPOL version and fail to connect. hostapd.conf upstream documents for eapol_version the following and that this is a known compatibility issue with version 2: // IEEE 802.1X/EAPOL version // hostapd is implemented based on IEEE Std 802.1X-2004 which defines EAPOL // version 2. However, there are many client implementations that do not handle // the new version number correctly (they seem to drop the frames completely). // In order to make hostapd interoperate with these clients, the version number // can be set to the older version (1) with this configuration value. // Note: When using MACsec, eapol_version shall be set to 3, which is // defined in IEEE Std 802.1X-2010. //eapol_version=2 For the wpa parameter, hostapd.conf upstream documents that this is a bitfield, configured as follows: // Enable WPA. Setting this variable configures the AP to require WPA (either // WPA-PSK or WPA-RADIUS/EAP based on other configuration). For WPA-PSK, either // wpa_psk or wpa_passphrase must be set and wpa_key_mgmt must include WPA-PSK. // Instead of wpa_psk / wpa_passphrase, wpa_psk_radius might suffice. // For WPA-RADIUS/EAP, ieee8021x must be set (but without dynamic WEP keys), // RADIUS authentication server must be configured, and WPA-EAP must be included // in wpa_key_mgmt. // This field is a bit field that can be used to enable WPA (IEEE 802.11i/D3.0) // and/or WPA2 (full IEEE 802.11i/RSN): // bit0 = WPA // bit1 = IEEE 802.11i/RSN (WPA2) (dot11RSNAEnabled) // Note that WPA3 is also configured with bit1 since it uses RSN just like WPA2. // In other words, for WPA3, wpa=2 is used the configuration (and // wpa_key_mgmt=SAE for WPA3-Personal instead of wpa_key_mgmt=WPA-PSK). //wpa=2 For client compatibility therefore: EAPOLv1 (802.1X-2001) should be used by default where WPA is enabled. EAPOLv2 (802.1X-2004) should be used by default where WPA is disabled. To fix this, we can therefore change in the script: set_default eapol_version 0 To the following: set_default eapol_version $((wpa & 1)) This therefore: 1) Sets eapol_version to 1 where WPA has been enabled via wpa bit0 being set. 2) Sets eapol_version to 0 where WPA has been disabled via wpa bit0 being unset. For usual configurations that only have WPA2 enabled, EAPOLv2 is then used. Signed-off-by: Nick Lowe <nick.lowe@gmail.com>

hostapd: update to git snapshot of 2018-03-26 The following patches were merged upstream: 000-hostapd-Avoid-key-reinstallation-in-FT-handshake.patch replaced by commit 0e3bd7ac6 001-Prevent-reinstallation-of-an-already-in-use-group-ke.patch replaced by commit cb5132bb3 002-Extend-protection-of-GTK-IGTK-reinstallation-of-WNM-.patch replaced by commit 87e2db16b 003-Prevent-installation-of-an-all-zero-TK.patch replaced by commit 53bb18cc8 004-Fix-PTK-rekeying-to-generate-a-new-ANonce.patch replaced by commit 0adc9b28b 005-TDLS-Reject-TPK-TK-reconfiguration.patch replaced by commit ff89af96e 006-WNM-Ignore-WNM-Sleep-Mode-Response-without-pending-r.patch replaced by commit adae51f8b 007-FT-Do-not-allow-multiple-Reassociation-Response-fram.patch replaced by commit 2a9c5217b 008-WPA-Extra-defense-against-PTK-reinstalls-in-4-way-ha.patch replaced by commit a00e946c1 009-Clear-PMK-length-and-check-for-this-when-deriving-PT.patch replaced by commit b488a1294 010-Optional-AP-side-workaround-for-key-reinstallation-a.patch replaced by commit 6f234c1e2 011-Additional-consistentcy-checks-for-PTK-component-len.patch replaced by commit a6ea66530 012-Clear-BSSID-information-in-supplicant-state-machine-.patch replaced by commit c0fe5f125 013-WNM-Ignore-WNM-Sleep-Mode-Request-in-wnm_sleep_mode-.patch replaced by commit 114f2830d Some patches had to be modified to work with changed upstream source: 380-disable_ctrl_iface_mib.patch (adding more ifdef'ery) plus some minor knits needed for other patches to apply which are not worth being explicitely listed here. For SAE key management in mesh mode, use the newly introduce sae_password parameter instead of the psk parameter to also support SAE keys which would fail the checks applied on the psk field (ie. length and such). This fixes compatibility issues for users migrating from authsae. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

hostapd: add support for subject validation The wpa_supplicant supports certificate subject validation via the subject match(2) and altsubject_match(2) fields. domain_match(2) and domain_suffix_match(2) fields are also supported for advanced matches. This validation is especially important when connecting to access points that use PAP as the Phase 2 authentication type. Without proper validation, the user's password can be transmitted to a rogue access point in plaintext without the user's knowledge. Most organizations already require these attributes to be included to ensure that the connection from the STA and the AP is secure. Includes LuCI changes via openwrt/luci#3444. From the documentation: subject_match - Constraint for server certificate subject. This substring is matched against the subject of the authentication server certificate. If this string is set, the server sertificate is only accepted if it contains this string in the subject. The subject string is in following format: /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as .example.com subject_match2 - Constraint for server certificate subject. This field is like subject_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. altsubject_match - Constraint for server certificate alt. subject. Semicolon separated string of entries to be matched against the alternative subject name of the authentication server certificate. If this string is set, the server sertificate is only accepted if it contains one of the entries in an alternative subject name extension. altSubjectName string is in following format: TYPE:VALUE Example: EMAIL:server@example.com Example: DNS:server.example.com;DNS:server2.example.com Following types are supported: EMAIL, DNS, URI altsubject_match2 - Constraint for server certificate alt. subject. This field is like altsubject_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_match - Constraint for server domain name. If set, this FQDN is used as a full match requirement for the server certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met. If no dNSName values are present, this constraint is matched against SubjectName CN using same full match comparison. This behavior is similar to domain_suffix_match, but has the requirement of a full match, i.e., no subdomains or wildcard matches are allowed. Case-insensitive comparison is used, so "Example.com" matches "example.com", but would not match "test.Example.com". More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed together. domain_match2 - Constraint for server domain name. This field is like domain_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_suffix_match - Constraint for server domain name. If set, this FQDN is used as a suffix match requirement for the AAA server certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met. If no dNSName values are present, this constraint is matched against SubjectName CN using same suffix match comparison. Suffix match here means that the host/domain name is compared one label at a time starting from the top-level domain and all the labels in domain_suffix_match shall be included in the certificate. The certificate may include additional sub-level labels in addition to the required labels. More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed together. For example, domain_suffix_match=example.com would match test.example.com but would not match test-example.com.

wpa_supplicant: improve generating phase2 config line for WPA-EAP WPA-EAP supports several phase2 (=inner) authentication methods when using EAP-TTLS, EAP-PEAP or EAP-FAST (the latter is added as a first step towards the UCI model supporting EAP-FAST by this commit) The value of the auth config variable was previously expected to be directly parseable as the content of the 'phase2' option of wpa_supplicant. This exposed wpa_supplicant's internals, leaving it to view-level to set the value properly. Unfortunately, this is currently not the case, as LuCI currently allows values like 'PAP', 'CHAP', 'MSCHAPV2'. Users thus probably diverged and set auth to values like 'auth=MSCHAPV2' as a work-around. This behaviour isn't explicitely documented anywhere and is not quite intuitive... The phase2-string is now generated according to $eap_type and $auth, following the scheme also found in hostap's test-cases: http://w1.fi/cgit/hostap/tree/tests/hwsim/test_ap_eap.py The old behaviour is also still supported for the sake of not breaking existing, working configurations. Examples: eap_type auth 'ttls' 'EAP-MSCHAPV2' -> phase2="autheap=MSCHAPV2" 'ttls' 'MSCHAPV2' -> phase2="auth=MSCHAPV2" 'peap' 'EAP-GTC' -> phase2="auth=GTC" Deprecated syntax supported for compatibility: 'ttls' 'autheap=MSCHAPV2' -> phase2="autheap=MSCHAPV2" I will suggest a patch to LuCI adding EAP-MSCHAPV2, EAP-GTC, ... to the list of Authentication methods available.

hostapd: backport BSSID black/whitelists This change adds the configuration options "bssid_whitelist" and "bssid_blacklist" used to limit the AP selection of a network to a specified (finite) set or discard certain APs. This can be useful for environments where multiple networks operate using the same SSID and roaming between those is not desired. It is also useful to ignore a faulty or otherwise unwanted AP. In many applications it is useful not just to enumerate a group of well known access points, but to use a address/mask notation to match an entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00). This is especially useful if an OpenWrt device with two radios is used to retransmit the same network (one in AP mode for other clients, one as STA for the uplink); the following configuration prevents the device from associating with itself, given that the own AP to be avoided is using the bssid 'C0:FF:EE:D0:0D:42': config wifi-iface option device 'radio2' option network 'uplink' option mode 'sta' option ssid 'MyNetwork' option encryption 'none' list bssid_blacklist 'C0:FF:EE:D0:0D:42/00:FF:FF:FF:FF:FF' This change consists of the following cherry-picked upstream commits: b3d6a0a8259002448a29f14855d58fe0a624ab76 b83e455451a875ba233b3b8ac29aff8b62f064f2 79cd993a623e101952b81fa6a29c674cd858504f (squashed to implement bssid_{white,black}lists) 0047306bc9ab7d46e8cc22ff9a3e876c47626473 (Add os_snprintf_error() helper) Signed-off-by: Stefan Tomanek <stefan.tomanek+openwrt@wertarbyte.de> SVN-Revision: 44438
