Jo-Philipp Wich a95ddaba02 uhttpd: add direct dependency on libjson-c
The OpenWrt buildroot ABI version rebuild tracker does not handle
transient dependencies, therefor add all libraries linked by uhttpd
as direct dependencies to the corresponding binary package definition.

This ensures that uhttpd is automatically rebuilt and relinked if any
of these libraries has its ABI_VERSION updated in the future.

Yousong Zhou 0299a4b73e dnsmasq: skip options that are not compiled in
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

Resolves FS#2281

Kevin Darbyshire-Bryant 021a9b4cb9 iproute2: add tc action ctinfo support
Add the userspace control portion of the backported kernelspace
act_ctinfo.

ctinfo is a tc action restoring data stored in conntrack marks to
various fields.  At present it has two independent modes of operation,
restoration of DSCP into IPv4/v6 diffserv and restoration of conntrack
marks into packet skb marks.

It understands a number of parameters specific to this action in
additional to the usual action syntax.  Each operating mode is
independent of the other so all options are optional, however not
specifying at least one mode is a bit pointless.

Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE]
		  [CONTROL] [index <INDEX>]

DSCP mode

dscp enables copying of a DSCP stored in the conntrack mark into the
ipv4/v6 diffserv field.  The mask is a 32bit field and specifies where
in the conntrack mark the DSCP value is located.  It must be 6
contiguous bits long. eg. 0xfc000000 would restore the DSCP from the
upper 6 bits of the conntrack mark.

The DSCP copying may be optionally controlled by a statemask.  The
statemask is a 32bit field, usually with a single bit set and must not
overlap the dscp mask.  The DSCP restore operation will only take place
if the corresponding bit/s in conntrack mark ANDed with the statemask
yield a non zero result.

eg. dscp 0xfc000000 0x01000000 would retrieve the DSCP from the top 6
bits, whilst using bit 25 as a flag to do so.  Bit 26 is unused in this
example.

CPMARK mode

cpmark enables copying of the conntrack mark to the packet skb mark.  In
this mode it is completely equivalent to the existing act_connmark
action.  Additional functionality is provided by the optional mask
parameter, whereby the stored conntrack mark is logically ANDed with the
cpmark mask before being stored into skb mark.  This allows shared usage
of the conntrack mark between applications.

eg. cpmark 0x00ffffff would restore only the lower 24 bits of the
conntrack mark, thus may be useful in the event that the upper 8 bits
are used by the DSCP function.

Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE]
		  [CONTROL] [index <INDEX>]
where :
	dscp MASK is the bitmask to restore DSCP
	     STATEMASK is the bitmask to determine conditional restoring
	cpmark MASK mask applied to restored packet mark
	ZONE is the conntrack zone
	CONTROL := reclassify | pipe | drop | continue | ok |
		   goto chain <CHAIN_INDEX>

Jason A. Donenfeld 593b487538 wireguard: bump to 0.0.20190601
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
4.2, due to the use of xgetbv without checking cpu flags for xsave support.
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.
But it also can't hurt, and probably best to stay updated.

Jason A. Donenfeld a1210f8888 wireguard: bump to 0.0.20190531
* tools: add wincompat layer to wg(8)

Consistent with a lot of the Windows work we've been doing this last cycle,
wg(8) now supports the WireGuard for Windows app by talking through a named
pipe. You can compile this as `PLATFORM=windows make -C src/tools` with mingw.
Because programming things for Windows is pretty ugly, we've done this via a
separate standalone wincompat layer, so that we don't pollute our pretty *nix
utility.

* compat: udp_tunnel: force cast sk_data_ready

This is a hack to work around broken Android kernel wrapper scripts.

* wg-quick: freebsd: workaround SIOCGIFSTATUS race in FreeBSD kernel

FreeBSD had a number of kernel race conditions, some of which we can vaguely
work around. These are in the process of being fixed upstream, but probably
people won't update for a while.

* wg-quick: make darwin and freebsd path search strict like linux

Correctness.

* socket: set ignore_df=1 on xmit

This was intended from early on but didn't work on IPv6 without the ignore_df
flag. It allows sending fragments over IPv6.

* qemu: use newer iproute2 and kernel
* qemu: build iproute2 with libmnl support
* qemu: do not check for alignment with ubsan

The QEMU build system has been improved to compile newer versions. Linking
against libmnl gives us better error messages. As well, enabling the alignment
check on x86 UBSAN isn't realistic.

* wg-quick: look up existing routes properly
* wg-quick: specify protocol to ip(8), because of inconsistencies

The route inclusion check was wrong prior, and Linux 5.1 made it break
entirely. This makes a better invocation of `ip route show match`.

* netlink: use new strict length types in policy for 5.2
* kbuild: account for recent upstream changes
* zinc: arm64: use cpu_get_elf_hwcap accessor for 5.2

The usual churn of changes required for the upcoming 5.2.

* timers: add jitter on ack failure reinitiation

Correctness tweak in the timer system.

* blake2s,chacha: latency tweak
* blake2s: shorten ssse3 loop

In every odd-numbered round, instead of operating over the state
    x00 x01 x02 x03
    x05 x06 x07 x04
    x10 x11 x08 x09
    x15 x12 x13 x14
we operate over the rotated state
    x03 x00 x01 x02
    x04 x05 x06 x07
    x09 x10 x11 x08
    x14 x15 x12 x13
The advantage here is that this requires no changes to the 'x04 x05 x06 x07'
row, which is in the critical path. This results in a noticeable latency
improvement of roughly R cycles, for R diagonal rounds in the primitive. As
well, the blake2s AVX implementation is now SSSE3 and considerably shorter.

* tools: allow setting WG_ENDPOINT_RESOLUTION_RETRIES

System integrators can now specify things like
WG_ENDPOINT_RESOLUTION_RETRIES=infinity when building wg(8)-based init
scripts and services, or 0, or any other integer.

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:
- 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

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).

Stefan Lippers-Hollmann 262229e924 hostapd: fix CVE-2019-9495
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()
  EAP-pwd: Use constant time and memory access for finding the PWE

Stefan Lippers-Hollmann af606d077f hostapd: fix CVE-2019-9494
SAE side-channel attacks

Published: April 10, 2019
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).

- 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.
