libvma connectivity is broken using upstream kernel > v6.10-rc1119^24

Issue type

Bug report

Configuration

• running rhel9/10 with kernel version > v6.10-rc1119^24 break libvma traffic:
• the issue appears during our userspace package update for RHEL 10 release and after updating to libvma version libvma-9.8.60-1 we saw that the traffic is not passing when using libvma and no connectivity at all after few more investigation we found that the main issue appeared after the following kernel change :
• 6e828dc60e50 (l2tp: fix ICMP error handling for UDP-encap sockets)
• OS:
• RHEL9/10

Actual behavior:

no traffic between nodes when using libvma

Expected behavior:

traffic pass between nodes

Steps to reproduce:

after installing kernel greater than v6.10-rc1119^24 kernel have this change 6e828dc60e50 (l2tp: fix ICMP error handling for UDP-encap sockets) run the following commands:

server:
LD_PRELOAD=libvma.so timeout --preserve-status --kill-after=2m 1m sockperf server -p 8787 -i <ip_address> #server

client:
LD_PRELOAD=libvma.so timeout --preserve-status --kill-after=2m 1m sockperf pp -d -p 8787 -i -t 10 --msg-size=1472
