[Kernel-packages] [Bug 1828035] Re: StrongSwan with GCM and large packet sizes produces unstable behavior
The 'gcm-aes-s390' patch landed today in bionic's release pocket. The work was done based on the kernel SRU of LP 1832623, which is now Fix Released.

A rough outlook is: in ~ less than 2 weeks - it's planned to come with the next proposed kernel.

Since there is a kernel SRU request in progress to include that patch anyway, ( addressed in LP 1832623 '[UBUNTU] kernel: Fix gcm-aes-s390 wrong scatter-gather list processing' - https://bugs.launchpad.net/ubuntu-z-systems/+bug/1832623 ) I suggest to wait until this hits -proposed and is ready for verification - if that is okay for you?! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1828035 Title: StrongSwan with GCM and large packet sizes produces unstable behavior Status in Ubuntu on IBM z Systems: Incomplete Status in linux package in Ubuntu: Confirmed Status in strongswan package in Ubuntu: Incomplete Bug description: StrongSwan with GCM and large packet sizes produces unstable behavior when used in Linux native environment. ---uname output--- Linux ubu01 4.15.0-42-generic #45-Ubuntu SMP Thu Nov 15 19:29:11 UTC 2018 s390x s390x s390x GNU/Linux Machine Type = 3906 / M04 (z14), LPAR (dedicated) ---Debugger--- A debugger is not configured ---Steps to Reproduce--- On two separate machines (Linux native), install StrongSwan and on both machines, configure the encryption with aes128gcm8 for IPsec.

[Kernel-packages] [Bug 1828035] Re: StrongSwan with GCM and large packet sizes produces unstable behavior
Thanks Tobias for the advise, adding a kernel Task to pull in the kernel team as well (confirmed to stop the bot from asking for logs). @bugproxy: "configure the encryption with aes128gcm8 for IPsec" can probably be done in more than one way. To avoid wasting effort could you just provide the config files you used on both ends This is -not- overriding the question of xnox if it works in a newer strongswan. @bugproxy: As the kernel might be important (see the comment above), another check is to verify if the same occurs with the HWE kernel "linux-generic-hwe-18.04" currently at 4.18.0.18.68. Furthermore you should try 5.1 from [1] This is -not- overriding the question of xnox if it works in a newer strongswan either.
