* compat: support building for RHEL-8.2
* compat: remove RHEL-7.6 workaround
Bleeding edge RHEL users should be content now (which includes the actual
RedHat employees I've been talking to about getting this into the RHEL kernel
itself). Also, we remove old hacks for versions we no longer support anyway.
* allowedips: remove previously added list item when OOM fail
* noise: reject peers with low order public keys
With this now being upstream, we benefit from increased fuzzing coverage of
the code, uncovering these two bugs.
* netns: ensure non-addition of peers with failed precomputation
* netns: tie socket waiting to target pid
An added test to our test suite for the above and a small fix for high-load CI
scenarios.

* curve25519: x86_64: replace with formally verified implementation
This comes from INRIA's HACL*/Vale. It implements the same algorithm and
implementation strategy as the code it replaces, only this code has been
formally verified, sans the base point multiplication, which uses code
similar to prior, only it uses the formally verified field arithmetic
alongside reproducable ladder generation steps. This doesn't have a
pure-bmi2 version, which means haswell no longer benefits, but the
increased (doubled) code complexity is not worth it for a single
generation of chips that's already old.
Performance-wise, this is around 1% slower on older microarchitectures,
and slightly faster on newer microarchitectures, mainly 10nm ones or
backports of 10nm to 14nm. This implementation is "everest" below:
Xeon E5-2680 v4 (Broadwell)
armfazh: 133340 cycles per call
everest: 133436 cycles per call
Xeon Gold 5120 (Sky Lake Server)

Currently, it is very cumbersome for a user to connect to a WPA-Enterprise
based network securely because the RADIUS server's CA certificate must first be
extracted from the EAPOL handshake using tcpdump or other methods before it can
be pinned using the ca_cert(2) fields. To make this process easier and more

support for validating against the built-in CA bundle when the ca-bundle

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

* socket: mark skbs as not on list when receiving via gro
Certain drivers will pass gro skbs to udp, at which point the udp driver
simply iterates through them and passes them off to encap_rcv, which is
where we pick up. At the moment, we're not attempting to coalesce these
into bundles, but we also don't want to wind up having cascaded lists of
skbs treated separately. The right behavior here, then, is to just mark
each incoming one as not on a list. This can be seen in practice, for
example, with Qualcomm's rmnet_perf driver. This lead to crashes on
OnePlus devices and possibly other Qualcomm 4.14 devices. But I fear
that it could lead to issues on other drivers on weird OpenWRT routers.

As announced on the mailing list, WireGuard will be in Linux 5.6. As a
result, the wg(8) tool, used by OpenWRT in the same manner as ip(8), is
moving to its own wireguard-tools repo. Meanwhile, the out-of-tree
kernel module for kernels 3.10 - 5.5 moved to its own wireguard-linux-
compat repo. Yesterday, releases were cut out of these repos, so this
commit bumps packages to match. Since wg(8) and the compat kernel module
are versioned and released separately, we create a wireguard-tools
Makefile to contain the source for the new tools repo. Later, when
OpenWRT moves permanently to Linux 5.6, we'll drop the original module
package, leaving only the tools. So this commit shuffles the build
definition around a bit but is basically the same idea as before.

This is to make life easier for users with customized build of
dnsmasq-full variant. Currently dnsmasq config generated by current
service script will be rejected by dnsmasq build lacking DHCP feature
- Options like --dhcp-leasefile have default values. Deleting them
from uci config or setting them to empty value will make them take on
default value in the end
- Options like --dhcp-broadcast are output unconditionally
Tackle this by
- Check availablility of features from output of "dnsmasq --version"
- Make a list of options guarded by HAVE_xx macros in src/options.c of
dnsmasq source code
- Ignore these options in xappend()
Two things to note in this implementation
- The option list is not exhaustive. Supposedly only those options that
may cause dnsmasq to reject with "unsupported option (check that
dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support)" are taken
into account here
- This provides a way out but users' cooperation is still needed. E.g.
option dnssec needs to be turned off, otherwise the service script
will try to add --conf-file pointing to dnssec specific anchor file
which dnsmasq lacking dnssec support will reject

There was an issue with the backport compat layer in yesterday's snapshot,
causing issues on certain (mostly Atom) Intel chips on kernels older than

This manifested itself simply at module load time. Indeed it's somewhat tricky
to support 33 different kernel versions (3.10+), plus weird distro
frankenkernels.
If OpenWRT doesn't support < 4.2, you probably don't need to apply this.

The advantage here is that this requires no changes to the 'x04 x05 x06 x07'

well, the blake2s AVX implementation is now SSSE3 and considerably shorter.

EAP-pwd missing commit validation
Published: April 10, 2019
Identifiers:
- CVE-2019-9497 (EAP-pwd server not checking for reflection attack)
- CVE-2019-9498 (EAP-pwd server missing commit validation for
scalar/element)
- CVE-2019-9499 (EAP-pwd peer missing commit validation for
scalar/element)
Latest version available from: https://w1.fi/security/2019-4/
Vulnerability
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) was discovered not to validate the received scalar and element
values in EAP-pwd-Commit messages properly. 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:

hostapd: fix SAE confirm missing state validation
Published: April 10, 2019
Identifiers:
- CVE-2019-9496 (SAE confirm missing state validation in hostapd/AP)
Latest version available from: https://w1.fi/security/2019-3/
Vulnerability
When hostapd is used to operate an access point with SAE (Simultaneous
Authentication of Equals; also known as WPA3-Personal), an invalid
authentication sequence could result in the hostapd process terminating
due to a NULL pointer dereference when processing SAE confirm
message. This was caused by missing state validation steps when
processing the SAE confirm message in hostapd/AP mode.
Similar cases against the wpa_supplicant SAE station implementation had
already been tested by the hwsim test cases, but those sequences did not
trigger this specific code path in AP mode which is why the issue was
not discovered earlier.
An attacker in radio range of an access point using hostapd in SAE
configuration could use this issue to perform a denial of service attack
by forcing the hostapd process to terminate.
Vulnerable versions/configurations
All hostapd versions with SAE support (CONFIG_SAE=y in the build
configuration and SAE being enabled in the runtime configuration).

EAP-pwd side-channel attack
Published: April 10, 2019
Identifiers:
- CVE-2019-9495 (cache attack against EAP-pwd)
Latest version available from: https://w1.fi/security/2019-2/
Vulnerability
Number of potential side channel attacks were recently discovered in the
SAE implementations used by both hostapd and wpa_supplicant (see
security advisory 2019-1 and VU#871675). EAP-pwd uses a similar design
for deriving PWE from the password and while a specific attack against
EAP-pwd is not yet known to be tested, there is no reason to believe
that the EAP-pwd implementation would be immune against the type of
cache attack that was identified for the SAE implementation. Since the
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) does not support MODP groups, the timing attack described against
SAE is not applicable for the EAP-pwd implementation.
A novel cache-based attack against SAE handshake would likely be
applicable against the EAP-pwd implementation. Even though the
wpa_supplicant/hostapd PWE derivation iteration for EAP-pwd has
protections against timing attacks, this new cache-based attack might
enable an attacker to determine which code branch is taken in the
iteration if the attacker is able to run unprivileged code on the victim
machine (e.g., an app installed on a smart phone or potentially a
JavaScript code on a web site loaded by a web browser). This depends on
the used CPU not providing sufficient protection to prevent unprivileged
applications from observing memory access patterns through the shared
cache (which is the most likely case with today's designs).
The attacker could use information about the selected branch to learn
information about the password and combine this information from number
of handshake instances with an offline dictionary attack. With
sufficient number of handshakes and sufficiently weak password, this
might result in full recovery of the used password if that password is
not strong enough to protect against dictionary attacks.
This attack requires the attacker to be able to run a program on the
target device. This is not commonly the case on an authentication server
(EAP server), so the most likely target for this would be a client
device using EAP-pwd.
The commits listed in the end of this advisory change the EAP-pwd
implementation shared by hostapd and wpa_supplicant to perform the PWE
derivation loop using operations that use constant time and memory
access pattern to minimize the externally observable differences from
operations that depend on the password even for the case where the
attacker might be able to run unprivileged code on the same device.
Vulnerable versions/configurations
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).
It should also be noted that older versions of wpa_supplicant/hostapd
prior to v2.7 did not include additional protection against certain
timing differences. The definition of the EAP-pwd (RFC 5931) does not
describe such protection, but the same issue that was addressed in SAE
earlier can be applicable against EAP-pwd as well and as such, that
implementation specific extra protection (commit 22ac3dfebf7b, "EAP-pwd:
Mask timing of PWE derivation") is needed to avoid showing externally
visible timing differences that could leak information about the
password. Any uses of older wpa_supplicant/hostapd versions with EAP-pwd
are recommended to update to v2.7 or newer in addition to the mitigation
steps listed below for the more recently discovered issue.
Possible mitigation steps
- Merge the following commits to wpa_supplicant/hostapd and rebuild:
OpenSSL: Use constant time operations for private bignums
Add helper functions for constant time operations
OpenSSL: Use constant time selection for crypto_bignum_legendre()

SAE side-channel attacks

Identifiers:
- VU#871675
- CVE-2019-9494 (cache attack against SAE)
Latest version available from: https://w1.fi/security/2019-1/
Vulnerability
Number of potential side channel attacks were discovered in the SAE
implementations used by both hostapd (AP) and wpa_supplicant
(infrastructure BSS station/mesh station). SAE (Simultaneous
Authentication of Equals) is also known as WPA3-Personal. The discovered
side channel attacks may be able to leak information about the used
password based on observable timing differences and cache access
patterns. This might result in full password recovery when combined with
an offline dictionary attack and if the password is not strong enough to
protect against dictionary attacks.
Cache attack
A novel cache-based attack against SAE handshake was discovered. This
attack targets SAE with ECC groups. ECC group 19 being the mandatory
group to support and the most likely used group for SAE today, so this
attack applies to the most common SAE use case. Even though the PWE
derivation iteration in SAE has protections against timing attacks, this
new cache-based attack enables an attacker to determine which code
branch is taken in the iteration if the attacker is able to run
unprivileged code on the victim machine (e.g., an app installed on a
smart phone or potentially a JavaScript code on a web site loaded by a
web browser). This depends on the used CPU not providing sufficient
protection to prevent unprivileged applications from observing memory
access patterns through the shared cache (which is the most likely case
with today's designs).
The attacker can use information about the selected branch to learn
information about the password and combine this information from number
of handshake instances with an offline dictionary attack. With
sufficient number of handshakes and sufficiently weak password, this
might result in full discovery of the used password.
This attack requires the attacker to be able to run a program on the
target device. This is not commonly the case on access points, so the
most likely target for this would be a client device using SAE in an
infrastructure BSS or mesh BSS.
The commits listed in the end of this advisory change the SAE
implementation shared by hostapd and wpa_supplicant to perform the PWE
derivation loop using operations that use constant time and memory
access pattern to minimize the externally observable differences from
operations that depend on the password even for the case where the
attacker might be able to run unprivileged code on the same device.
Timing attack
The timing attack applies to the MODP groups 22, 23, and 24 where the
PWE generation algorithm defined for SAE can have sufficient timing
differences for an attacker to be able to determine how many rounds were
needed to find the PWE based on the used password and MAC
addresses. When the attack is repeated with multiple times, the attacker
may be able to gather enough information about the password to be able
to recover it fully using an offline dictionary attack if the password
is not strong enough to protect against dictionary attacks. This attack
could be performed by an attacker in radio range of an access point or a
station enabling the specific MODP groups.
This timing attack requires the applicable MODP groups to be enabled
explicitly in hostapd/wpa_supplicant configuration (sae_groups
parameter). All versions of hostapd/wpa_supplicant have disabled these
groups by default.
While this security advisory lists couple of commits introducing
additional protection for MODP groups in SAE, it should be noted that
the groups 22, 23, and 24 are not considered strong enough to meet the
current expectation for a secure system. As such, their use is
discouraged even if the additional protection mechanisms in the
implementation are included.
Vulnerable versions/configurations
All wpa_supplicant and hostapd versions with SAE support (CONFIG_SAE=y
in the build configuration and SAE being enabled in the runtime
configuration).

Possible mitigation steps
- Merge the following commits to wpa_supplicant/hostapd and rebuild:
OpenSSL: Use constant time operations for private bignums
Add helper functions for constant time operations
OpenSSL: Use constant time selection for crypto_bignum_legendre()
SAE: Minimize timing differences in PWE derivation
SAE: Avoid branches in is_quadratic_residue_blind()
SAE: Mask timing of MODP groups 22, 23, 24
SAE: Use const_time selection for PWE in FFC
SAE: Use constant time operations in sae_test_pwd_seed_ffc()
These patches are available from https://w1.fi/security/2019-1/
- Update to wpa_supplicant/hostapd v2.8 or newer, once available
- In addition to either of the above alternatives, disable MODP groups
1, 2, 5, 22, 23, and 24 by removing them from hostapd/wpa_supplicant
sae_groups runtime configuration parameter, if they were explicitly
enabled since those groups are not considered strong enough to meet
current security expectations. The groups 22, 23, and 24 are related
to the discovered side channel (timing) attack. The other groups in
the list are consider too weak to provide sufficient security. Note
that all these groups have been disabled by default in all
hostapd/wpa_supplicant versions and these would be used only if
explicitly enabled in the configuration.
- Use strong passwords to prevent dictionary attacks

* allowedips: initialize list head when removing intermediate nodes
Fix for an important regression in removing allowed IPs from the last
snapshot. We have new test cases to catch these in the future as well.
* tools: warn if an AllowedIP has a nonzero host part
If you try to run `wg set wg0 peer ... allowed-ips 192.168.1.82/24`, wg(8)
will now print a warning. Even though we mask this automatically down to
192.168.1.0/24, usually when people specify it like this, it's a mistake.
* wg-quick: add 'strip' subcommand
The new strip subcommand prints the config file to stdout after stripping
it of all wg-quick-specific options. This enables tricks such as:
`wg addconf $DEV <(wg-quick strip $DEV)`.
* tools: avoid unneccessary next_peer assignments in sort_peers()
Small C optimization the compiler was probably already doing.
* peerlookup: rename from hashtables

Suggested tweaks from Dave Miller.
* blake2s: simplify
* blake2s: remove outlen parameter from final
The blake2s implementation has been simplified, since we don't use any of the
fancy tree hashing parameters or the like. We also no longer separate the
output length at initialization time from the output length at finalization
time.

Instead of creating host-routes depending on fwmark as (accidentally)
pushed by commit
1e8bb50b93 ("wireguard: do not add host-dependencies if fwmark is set")
use a new config option 'nohostroute' to explicitely prevent creation
of the route to the endpoint.

The 'fwmark' option is used to define routing traffic to
wireguard endpoints to go through specific routing tables.
In that case it doesn't make sense to setup routes for
host-dependencies in the 'main' table, so skip setting host
dependencies if 'fwmark' is set.

* wg-quick: freebsd: allow loopback to work
FreeBSD adds a route for point-to-point destination addresses. We don't
really want to specify any destination address, but unfortunately we
have to. Before we tried to cheat by giving our own address as the
destination, but this had the unfortunate effect of preventing
loopback from working on our local ip address. We work around this with
yet another kludge: we set the destination address to 127.0.0.1. Since
127.0.0.1 is already assigned to an interface, this has the same effect
of not specifying a destination address, and therefore we accomplish the
intended behavior. Note that the bad behavior is still present in Darwin,
where such workaround does not exist.
* tools: remove unused check phony declaration
* highlighter: when subtracting char, cast to unsigned
* chacha20: name enums
* tools: fight compiler slightly harder
* tools: c_acc doesn't need to be initialized
* queueing: more reasonable allocator function convention
Usual nits.
* systemd: wg-quick should depend on nss-lookup.target
Since wg-quick(8) calls wg(8) which does hostname lookups, we should
probably only run this after we're allowed to look up hostnames.
* compat: backport ALIGN_DOWN
* noise: whiten the nanoseconds portion of the timestamp
This mitigates unrelated sidechannel attacks that think they can turn
WireGuard into a useful time oracle.
* hashtables: decouple hashtable allocations from the main device allocation
The hashtable allocations are quite large, and cause the device allocation in
the net framework to stall sometimes while it tries to find a contiguous
region that can fit the device struct. To fix the allocation stalls, decouple
the hashtable allocations from the device allocation and allocate the
hashtables with kvmalloc's implicit __GFP_NORETRY so that the allocations fall
back to vmalloc with little resistance.
* chacha20poly1305: permit unaligned strides on certain platforms
The map allocations required to fix this are mostly slower than unaligned
paths.
* noise: store clamped key instead of raw key
This causes `wg show` to now show the right thing. Useful for doing
comparisons.
* compat: ipv6_stub is sometimes null
On ancient kernels, ipv6_stub is sometimes null in cases where IPv6 has
been disabled with a command line flag or other failures.
* Makefile: don't duplicate code in install and modules-install
* Makefile: make the depmod path configurable
* queueing: net-next has changed signature of skb_probe_transport_header
A 5.1 change. This could change again, but for now it allows us to keep this
snapshot aligned with our upstream submissions.
* netlink: don't remove allowed ips for new peers
* peer: only synchronize_rcu_bh and traverse trie once when removing all peers
* allowedips: maintain per-peer list of allowedips
This is a rather big and important change that makes it much much faster to do
operations involving thousands of peers. Batch peer/allowedip addition and
clearing is several orders of magnitude faster now.

Currently it seems impossible to configure /etc/config/dhcp to achieve
the following use case
- run dnsmasq with no-resolv
- re-generate /etc/resolv.conf with "nameserver 127.0.0.1"
Before this change, we have to set resolvfile to /tmp/resolv.conf.auto
to achive the 2nd effect above, but setting resolvfile requires noresolv
being false.
A new boolean option "localuse" is added to indicate that we intend to
use dnsmasq as the local dns resolver. It's false by default and to
align with old behaviour it will be true automatically if resolvfile is
set to /tmp/resolv.conf.auto

Opkg treats text after a version number as higher than without:
~# opkg compare-versions "2.80rc1" "<<" "2.80"; echo $?
1
~# opkg compare-versions "2.80rc1" ">>" "2.80"; echo $?
0
This causes opkg not offering final release as upgradable version, and
even refusing to update, since it thinks the installed version is
higher.
This can be mitigated by adding ~ between the version and the text, as ~
will order as less than everything except itself. Since 'r' < 't', to
make sure that test will be treated as lower than rc we add a second ~
before the test tag. That way, the ordering becomes
2.80~~test < 2.80~rc < 2.80
which then makes opkg properly treat prerelease versions as lower.
