EASession return nil on iOS18
On iOS 18.x when try to create EASession we get nil, but on iOS 17.x everything works. We have app which use USB cable for connecting external accessories. Scenario is when we have fresh instal, connecting with accessory work fine, EASession is created, streams are opened. When we unplug USB, we close streams, remove any reference to session and accessory, remove accessory delegate. When plug it again, creating EASession is returning nil. Only after restarting iPhone, we can create new EASession with appropriate protocol and accessory. Every next attempt without reseting iPhone is failing. Logs from accessory is following: 00:05:51.811000 : onUSBDeviceFound(pDevice=0xffc818)) iPhone USB device already in the device list w/id=1 -> update status now[21;1H 00:05:51.830000 : setConnectionStatus(status=connected) [devId=1] state updated -> forward[21;1H Capabilities indicate HostMode possibility => role switch is triggered 00:05:52.848000 : updateDIPODeviceConnections() iPhoneUSB w/caps=5 (=CarPlay or HostMode), deviceTag=2 in Device mode -> request role switch[21;1H Role switch seems to be successful 00:05:54.914000 : setSwitching('stable') changed[21;1H 00:05:54.915000 : updateDIPODeviceConnections() iPhoneUSB w/caps=2, id=1, deviceTag=2 and native transport -> request app launch and call connectUSB[21;1H 00:05:54.967000 : ConnectiAP2(05ac:12a8, s/n='00008101000160921E90801E', writeFD='/dev/ffs/ep3', readFD='/dev/ffs/ep4', hostMode){3}[21;1H Native transport should become available but does not (the following line is not present for failed case.

Also what is strange is that it works on fresh instal/restart iPhone, but not working on second attempt?

L2TP VPN broken on MacOS 13/Ventura
Dove in and upgraded two Macs today to beta 1. Unfortunately, it appears L2TP VPN is broken or something changed in the way it works. I can longer get a connection to any VPN concentrator I used previously. I tested with Cisco Anyconnect SSL VPN client and can connect to the same concentrators (as they're configured to accept L2TP or SSL clients). I also tested from my phone running iOS 16 beta and it still works for the L2TP connections. The Mac not working with L2TP VPN ppp.log shows this Fri Jun 10 19:18:52 2022 : L2TP connecting to server 'IP removed' (IP removed)... Fri Jun 10 19:18:52 2022 : IPSec connection started Fri Jun 10 19:18:52 2022 : IPSec phase 1 client started Fri Jun 10 19:19:02 2022 : IPSec connection failed Connecting a Mac successfully on 12.4 the log shows Fri Jun 10 19:12:33 2022 : L2TP connecting to server 'IP removed' (IP removed)... Fri Jun 10 19:12:33 2022 : IPSec connection started Fri Jun 10 19:12:33 2022 : IPSec phase 1 client started Fri Jun 10 19:12:33 2022 : IPSec phase 1 server replied Fri Jun 10 19:12:34 2022 : IPSec phase 2 started Fri Jun 10 19:12:34 2022 : IPSec phase 2 established Fri Jun 10 19:12:34 2022 : IPSec connection established (and then a ton more lines of the entire process ending with client getting an IP that I won't bother posting) VPN wasn't high on my list of apps I was concerned about breaking with the beta. But, now that it is broke and I need it for work I'm kinda screwed myself. Anyway, if anyone knows a way to fix this please let me know.
