Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

"LC_ALL=C", but you're not using some dated AUR version.
You could try to build wpa_supplicant and add the 2nd patch in #21 and see whether you still need to change the configuration.

So, the answer of

Is this a pontential bug, I just need waiting update ?
Or I should modify openssl.cnf file by myself ?

Is, there will no fix, I need modify relevant files to fix low version problem. (?)

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

Wait, are you the OP w/ a different account or do you encounter the exact same error?
For the latter you should first test whether the workaround in #20 works for you.
If so or if you're the OP, the next step would be to build wpa_supplicant w/ https://w1.fi/cgit/hostap/commit/?id=e9 … 9e0e15007e applied and see whether that allows you to remove the workaround in #20

I'm not OP, I just got exact same error:

https://drive.google.com/file/d/1-n44pp … sp=sharing wpa_supplicant-2:2.10-8.1-x86_64.pkg.tar.zst

I've manually compiled the package by deleting codes in https://w1.fi/cgit/hostap/commit/?id=e9 … 9e0e15007e, with configuration from LFS https://www.linuxfromscratch.org/blfs/v … icant.html
And I've tested your package wpa_supplicant-2:2.10-8.1-x86_64.pkg.tar.zst

Both can not work ;(

Downgrade openssl from 3.1.1 to 3.0.9 solved the problem, but it breaks many other things ....

Because this is a problem related to openssl, I dont think recompile wpa_supplicant can solved the problem (?)

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

It is an intended change in OpenSSL 3.1 so not considered a bug in OpenSSL.  wpa_supplicant should be downgrading the OpenSSL security level as required.  I would suggest trying the latest commit from https://w1.fi/hostap.git if the issue is still present contact the hostap mailing list.

In the meantime you could btw. also test the behavior w/ iwd instead of wpa_supplicant

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

I think it is possible using the existing code by adjusting the config based on https://w1.fi/cgit/hostap/commit/?id=58 … 360d4bb67f
TLS_CONN_ENABLE_TLSv1_0 is set when tls_disable_tlsv1_0=0 is set in the right place in the config similarly TLS_CONN_ENABLE_TLSv1_1 is set when tls_disable_tlsv1_1=0
Their use is covered in /usr/share/doc/wpa_supplicant/wpa_supplicant.conf but I am unclear where precisely they should go.

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

TLS_CONN_ENABLE_TLSv1_0 is set when tls_disable_tlsv1_0=0 is set in the right place in the config similarly TLS_CONN_ENABLE_TLSv1_1 is set when tls_disable_tlsv1_1=0
Their use is covered in /usr/share/doc/wpa_supplicant/wpa_supplicant.conf but I am unclear where precisely they should go.

tls_disable_tlsv1_0 as well as tls_disable_tlsv1_1 is parsed in src/eap_peer/eap_tls_common.c of wpa_supplicant:

        if (os_strstr(txt, "tls_disable_tlsv1_1=1"))
                params->flags |= TLS_CONN_DISABLE_TLSv1_1;
        if (os_strstr(txt, "tls_disable_tlsv1_1=0")) {
                params->flags &= ~TLS_CONN_DISABLE_TLSv1_1;
                params->flags |= TLS_CONN_ENABLE_TLSv1_1;
        }

The codes set parameter's flag with TLS_CONN_DISABLE_TLSv1_1, then this flag is checked in src/crypto/tls_openssl.c:

#ifdef SSL_OP_NO_TLSv1_1
        if (flags & TLS_CONN_DISABLE_TLSv1_1)
                SSL_set_options(ssl, SSL_OP_NO_TLSv1_1);
        else
                SSL_clear_options(ssl, SSL_OP_NO_TLSv1_1);
#endif /* SSL_OP_NO_TLSv1_1 */

According to OpenSSL API document https://www.openssl.org/docs/man3.1/man … tions.html, I'm not sure the set option takes real effect under openssl 3.1.1:

SSL_OP_NO_SSLv3, SSL_OP_NO_TLSv1, SSL_OP_NO_TLSv1_1, SSL_OP_NO_TLSv1_2, SSL_OP_NO_TLSv1_3, SSL_OP_NO_DTLSv1, SSL_OP_NO_DTLSv1_2

    These options turn off the SSLv3, TLSv1, TLSv1.1, TLSv1.2 or TLSv1.3 protocol versions with TLS or the DTLSv1, DTLSv1.2 versions with DTLS, respectively. As of OpenSSL 1.1.0, these options are deprecated, use SSL_CTX_set_min_proto_version(3) and SSL_CTX_set_max_proto_version(3) instead.

How ever this patch https://w1.fi/cgit/hostap/commit/?id=58 … 360d4bb67f, the should work, theoretically ...
I'll try this patch latter ...

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

I'm sure I found a perfect solution based on current wpa_supplicant version.
Here is the prove.

With 2 difference configuration file:

[root@XSignBlade ~]# diff /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant-wired-enp101s0f3u1u4.conf 
10a11

Try to auth with wpa_supplicant, one failed with unsupported protocol, one succeed:

}

wpa_supplicant package information:

[root@XSignBlade ~]# LC_ALL=C pacman -Qo /usr/bin/wpa_supplicant 
/usr/bin/wpa_supplicant is owned by wpa_supplicant 2:2.10-8

ONE MORE QUESTION:
I'm using NetworkManager to manage my network, networkmanager interactive with wpa_supplicant by DBUS message, my question is, how can I pass a configuration to wpa_supplicant with networkmanager ?

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

Looking at https://gitlab.freedesktop.org/NetworkM … tags#L1385 I think there should be a NetworkManager setting to configure tls_disable_tlsv1_0 and tls_disable_tlsv1_1.

Looking at https://gitlab.freedesktop.org/NetworkM … tags#L1385 I think there should be a NetworkManager setting to configure tls_disable_tlsv1_0 and tls_disable_tlsv1_1.

Found it, it can be set by configuration file, I dont find GUI method to set it.

In /etc/NetworkManager/system-connections/, which need root privilege to access, there are many configurations end with '.nmconnection'.

[root@XSignBlade hacksign]# whoami
root
[root@XSignBlade hacksign]# ls /etc/NetworkManager/system-connections/
'My Home Wireless AP Name.nmconnection'  'Some Other Network I ever connected.nmconnection'  WiredNetwork.nmconnection

Find the one which you want lower TLS security level (it's WiredNetwork.nmconnection, by my example), under 802-1x section add phase1-auth-flags configuration:

[root@XSignBlade]# cat /etc/NetworkManager/system-connections/WiredNetwork.nmconnection 
......

[802-1x]
......
phase1-auth-flags=32
......

......

I believe there will be more and more people will got this error with new version of OpenSSL, so is any body can add the solution to ArchWiki ?

The solution is #36 floor for wpa_supplicant and #38 for NetworkManager of this thread

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

The wpa_supplicant must have this patch (https://w1.fi/cgit/hostap/commit/?id=58 … 360d4bb67f), which has already patched in ArchLinux repository:

NetworkManager's version must above 1.41.5-dev

I confirm this solution for NetworkManager. Thanks so much. However, IMHO this is clearly a bug that must be patched/automated for PEAP bindings.

Thanks all for the info.

I would suggest contacting upstream wpa_supplicant to see if automation is still possible with OpenSSL 3.1.

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

What is the proper workaround for this? For example is there a way to change some config? I downgraded the `openssl` package (and I'm ignoring it during upgrades), but many packages depend on it. For example, the latest `openssh` doesn't work without the latest `openssl`, so I had to downgrade SSH. Who knows what else will stop working... We need a long-term solution until wpa_suplicant is fixed upstream, because who knows when that will happen.

BTW, the bug on the Arch Linux side is https://bugs.archlinux.org/task/78770

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

Thanks and sorry. I saw the wpa_suplicant workaround, but that wasn't useful to me, but I somehow missed the NetworkManager one. It's important to note that if you configure NetworkManager connections via some UI, if the UI doesn't support passing custom parameters, this workaround would get overwritten.

I had the same problem too, probably after the openssl update and this solved for me, thank you so much.
I would add the tag "eduroam" and "wifi unina" cause I got this problem on my university WLAN

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

Adding the

phase1-auth-flags=32

line to my NetworkManager config file worked for me as well as a (hopefully temporary) workaround, though it seems to be a bit finicky, and doesn't actually work unless I run

nmcli connection up eduroam

from the command line. Trying to connect using the Xfce NetworkManager applet still fails.

Re: [SOLV] After upgrade to OpenSSL 3.1.1 WPA2 Enterprise Wifi Auth broken

I was trying to connect to my university's wifi. So...

Based on #36 what worked for me is:

ctrl_interface=/var/run/wpa_supplicant_new
#ctrl_interface_group=wheel
network={
  ssid="eduroam"
  scan_ssid=1
  key_mgmt=WPA-EAP
  
  # Credentials.
  # This example is only for password-based logins.
  identity="..."
  password="..."

  
  eap=TTLS
  auth_alg=OPEN
  phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0"
  phase2="autheap=PAP"
}

and then for some reason everything in /etc/resolv.conf was deleted, so I had to write in that file:

nameserver 1.1.1.1

because without it the connection appeared as 'limited'
