I'm trying to setup a WiFi Access Point with a Raspberry Pi 3B+ having 802.11w enabled.
Kernel version: Linux efb-ap-0 4.19.66-Re4son-v7+ #1 SMP Sun Aug 18 22:25:39 AEST 2019 armv7l GNU/Linux
Driver: brcmfmac
hostapd (Deb package): 2:2.9-1 armel
During the 4-Way Handshake, wpa_supplicant immediatly disconnects at the 3/4 msg, with following logs:
wlan0: WPA: IE in 3/4 msg does not match with IE in Beacon/ProbeResp (src=b8:27:eb:3b:3f:0e)
WPA: RSN IE in Beacon/ProbeResp - hexdump(len=28): 30 1a 01 00 00 0f ac 04 01 00 00 0f ac 04 01 00 00 0f ac 06 c0 00 00 00 00 0f ac 06
WPA: RSN IE in 3/4 msg - hexdump(len=26): 30 18 01 00 00 0f ac 04 01 00 00 0f ac 04 02 00 00 0f ac 02 00 0f ac 06 c0 00
Comparing 3/4 msg hexdump and Beacon hexdump via Wireshark shows that the Beacon contains the following additional fields that are not in the 3/4 msg: PMKID Count (0x00 00)+ PMKID List + Group Management Cipher Suite
(0x00 0f ac 06).
Why is the 3/4 msg not matching the Beacon ? Is this an issue in hostapd ? in driver ? in hostapd<->driver communication ?
Thanks for any information about that.
You can find below the hostapd.conf content:
interface=wlan0
driver=nl80211
logger_syslog=-1
logger_syslog_level=2
auth_algs=1
wpa_pairwise=CCMP
rsn_pairwise=CCMP

I am trying to use mitmproxy to look at the traffic from my win32 schannel tls client. But when I try to use mitmproxy the following messages throw an "Bad HTTP request line" error with a leading 0 in the binary dump that does not exsist in the data that my client sends (I have checked with a little python server).
"CONNECT www.example.com:443 HTTP/1.0\r\n\r\n"

Now my question: Is this just a lack of understanding in how proxys and tls work or an error from mitmproxy?
As part of installation of linux, I would like to set the "console device properties"(example, console=ttyS0,115200n1) via the kernel cmdline for Intel based platform.
There is No VGA console, only serial consoles via COM interface.
On these systems BIOS already has the required settings to interact using the appropriate serial port.
I see that EFI has variables ConIn, ConOut, ConErr which I am able to see from /sys/firmware/efi but unable to decode the contents of it.
Is it possible to identify which COM port is being used by the BIOS by examining the efi variables.
Example, of the EFI var on my box.

The contents of the ConOut variable are described in the UEFI specification - current version (2.8B):
3.3 - globally defined variables:
| Name | Attribute | Description |
|---------|------------|------------------------------------------------|
| ConOut | NV, BS, RT | The device path of the default output console. |
For information about device paths, we have:
10 - Protocols — Device Path Protocol:
Apart from the initial description of device paths, table 44 shows you the Generic Device Path Node structure, from which we can start decoding the contents of the variable.
The type of the first node is 0x02, telling us this node describes an ACPI device path, of 0x000c bytes length. Now jump down to 10.3.3 - ACPI Device Path and table 52, which tells us 1) that this is the right table (subtype 0x01) and 2) that the default ConOut has a _HID of 0x0a03410d and a _UID of 0.
The next node has a type of 0x01 - a Hardware Device Path, described further in 10.3.2, in this case table 46 (SubType is 0x01) for a PCI device path.
The next node describes a Messaging Device Path of type UART and so on...
Still, this only tells you what UEFI considers to be its default console, SPCR is what an operating system is supposed to be looking at for serial consoles. Unfortunately, on X86 the linux kernel handily ignores SPCR apart from for earlycon. I guess this is what you're trying to work around. It might be good to start some discussion on kernel development lists about whether to fix that and have X86 work like ARM64.
In my case since I know that console port is a "Serial IOPORT",
I could get the details now as follows.
a. Get hold of the /sys/firmware/acpi/tables/SPC table.
b. Read the Address offset 44-52. Actually one the last two bytes suffice.
Reference:
a. https://learn.microsoft.com/en-us/windows-hardware/drivers/serports/serial-port-console-redirection-table states that
Base Address 12 40
The base address of the Serial Port register set described using the ACPI Generic Address Structure.
0 = console redirection disabled

I'm using Akka Streams to create a TCP server using akka.stream.scaladsl.TLS with client certificate authentication. I'm working on creating an echo server as a first proof of concept.
In the meantime, I'm new to Scala/Akka/Akka Streams and so I created a similar server and TCP client in Python to provide tooling in testing my work in Scala. The Python server/client are functional using client cert authentication. When connecting to the server, the client takes the following steps:
Creates and configures an SSLContext
Creates a socket using socket.create_connection()
Wraps the socket with the SSLContext using SSLContext.wrap_socket(). This creates the peer connection
Once connected, prints the server certificate
Infinite loop asking for input and sending each input to the server
I believe I have the server completed using Akka Streams and akka.stream.scaladsl.TLS, but when I attempt to connect using my Python client the client never gets past connecting to the peer using context.wrap_socket(sock, server_hostname=host). The server successfully binds the TCP connection and creates the corresponding IncomingConnection object. The client/server also never timeout (the client just sits awaiting the handshake?).
My biggest problem is that I see no information from my TLS BidiFlow, akka.stream.scaladsl.TLS. I have no idea what step in the handshake I'm stuck at, which makes troubleshooting very difficult.
Is there any way to output some information throughout the TLS handshake process? It seems as though all of the functionality is encapsulated and I don't know if there's any way to troubleshoot.
Otherwise, I'm attempting to troubleshoot with openssl and get the following:
bash$ openssl s_client -connect myserver.com:443 -state -debug

SSL_connect:unknown state
At which point openssl just hangs.
The Akka TLS support uses the built in Java TLS support behind the scenes, so to get debug output for TLS you'll have to enable debugging for that. It can be done through passing a system property to the JVM when starting it like so -Djavax.net.debug=all
Ultimately I found that the ssl-config logging is very sparse and wasn't helpful to resolving my issue. It does provide some debugging information but not much. Much better for debugging the TLS handshake is to use the -Djavax.net.debug=all flag when running the JVM. However, even this provides mixed results. For example, the resulting error I received is that the server couldn't find a matching cipher suite. Eventually I resolved my issue by realizing that when creating the input streams for my keystore/truststore I was specifying my path incorrectly.
Note for anyone coming across this: if you specify your keystore and truststore incorrectly the resulting input streams will be null and SSLContext.init will happily use these and provide an error that is unrelated to the keystore/truststore! This was very difficult to troubleshoot due to the incorrect error handling in SSLContext.
This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

The facebook connection either hangs after the client sends its hello buffer and never receives the server hello response, or returns with an error code if I pass in a cipher it recognizes. This happens with both -tls1 and -ssl3. I've tried every parameter to openssl I can think of.
apt-cache showpkg openssl
...
Provides:
1.0.1-4ubuntu5.5 -
1.0.1-4ubuntu5.3 -
1.0.1-4ubuntu3 -
I've also tried every parameter I can think of to curl but with no success, because it uses openssl under the hood.
I'm concerned that Ubuntu can't establish secure connections (an astounding statement, I realize). After two solid days of beating my head against this problem, I'm basically praying at this point that someone knows a workaround. I'm considering a downgrade to OpenSSL 1.0.0 or using libcurl4-dev with gnutls-dev instead. Both solutions leave a rotten taste in my mouth. Thanks in advance for any help you can provide.
P.S. all of this work is so that my server can interface with external https REST APIs. I consider this a fundamental requirement in any webserver today, no excuses.
UPDATE: Here is my output without passing a cipher. It doesn't matter if I pass -CAfile or not either:

SSL_connect:unknown state
Why are you passing -cipher SRP-AES-256-CBC-SHA when connecting to graph.facebook.com? Facebook certainly doesn't support SRP: http://srp.stanford.edu/.
Does it work if you don't pass that?
Also, can you give the IP address that you're getting? With 69.171.229.17, I can reproduce that exact ClientHello (modulo the nonce and with RC4-SHA are the only cipher save the SCSV) and I get a successful handshake.
Lastly, have you tried doing over an SSH tunnel to somewhere else? Sadly, when deploying TLS features in Chrome we have repeatedly found networking hardware that breaks TLS connections. (Although I can't think of a case where -ssl3 wouldn't fix it unless the hardware was actively trying to censor connections.)
Setting the MTU on my Ubuntu box from 1500 to 1496 (due to one of our firewalls being set too low) allows me to receive a response from the server without having to reboot (be sure to call ifconfig first and write down your original MTU which should be 1500):
sudo ifconfig eth0 mtu 1496
I discovered my MTU by pinging with successively larger buffers (add 28 bytes for UDP header):
Fails for 1472 + 28 = 1500:
ping -s 1472 facebook.com
PING facebook.com (66.220.158.16) 1472(1500) bytes of data.
...
Works for 1468 + 28 = 1496:
ping -s 1468 facebook.com
PING facebook.com (69.171.229.16) 1468(1496) bytes of data.
1476 bytes from www-slb-ecmp-06-prn1.facebook.com (69.171.229.16): icmp_req=1 ttl=242 time=30.0 ms
...
With 1496 I'm now able to curl to facebook.com:
curl -v https://facebook.com

I personally think that MTU should have absolutely nothing to do with what the user sees at the stream level with TCP so I hope the OpenSSL folks fix this. I also wish that someone would invent an automagic bug submitter for bugs that are profoundly widespread and time-sucking.
Upgraded Webbit to 0.4.6 to use the new SSL support but immediately realized that all wss:// handshakes are failing silently and I don't have any errors to show for it. Chrome only reports a "success" for a response without a HTTP code or any other headers. I check server logs and it doesn't even register an "open" event.
The catch here is that any ws:// connection works great. So what could be possible problems and how can I get an error out of it? Could it be something wrong with the java keystore and SSL handshake?
Edit
I was able to find an openSSL command for a test handshake. Here's the output:
SSL_connect:before/connect initialization
SSL_connect:SSLv2/v3 write client hello A
SSL_connect:error in SSLv2/v3 read server hello A
Edit 2
I realized I could debug this further

Edit 3
Ok I've nailed the problem to Webbit initialization, but it doesn't throw any errors so I could use some input to getting getResourceAsStream functioning properly. Here's how the server is initialized:
def startWebSocketServer(webSocketHandler:PartialFunction[WebSocketEvent, Unit]) {
val webServer = WebServers.createWebServer(port)
try {
webServer.setupSsl(getClass.getResourceAsStream("/keystore"), "webbit")
webServer.add("/", new WebSocketEventAdapter(webSocketHandler))
webServer.start
} catch {
case e => e.printStackTrace()
}
}
Unfortunately setupSsl won't output any information, and I've tried both what I thought would be the path and inserting a fake path. In either case, I can't get an error. How on earth would I properly locate the path? Thanks!
The OMFG Answer
In a hysterical twist of fate, I found the problem. This particular issue took up 48 hours of my time, but the cause was not even code related and a funny miscommunication.
So as it turns out, another developer had copied our websocket code into a new file he was working on for development. All this time we were trying to debug code in a file that wasn't even executing at run-time. So upon further investigation we scrolled to the bottom of a very long and different file, and found the webbit init code and excuted it perfectly.
Moral of the story: don't commit an incomplete file to the master branch and point everyone there for debugging ;)
