Fix this by noting during SYN receive processing that an acceptable Fast Open option was used, and provide this to userland via getsockopt TCP_INFO. ==================== Link: https://patch.msgid.link/20250423124334.4916-1-jgh@exim.org Signed-off-by: Jakub Kicinski --- a764e8114d2d80e8b0f453084b2e9fcc6454b7a1
