            Bug ID: 259380
           Summary: linux_recvfrom -1 errno -22 Invalid argument
           Product: Base System
           Version: 13.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: jasonmader@gmail.com

In a FreeBSD 13.0 jail with Linux compatibility, one pair of Linux daemon and
utility programs do not communicate properly. They used to work in FreeBSD
11.2. Here is a ktrace of the daemon receiving part of a message; it's like
this for every 6 bytes. I am guessing the problem is "linux_recvfrom -1 errno
-22 Invalid argument"

 92539 rlm      CALL  linux_select(0x4000,0x85e6d8,0,0,0x7fffffffddd0)
 92539 rlm      RET   linux_select 1
 92539 rlm      CALL 
 92539 rlm      GIO   fd 4 read 6 bytes
 92539 rlm      RET   linux_recvfrom -1 errno -22 Invalid argument
 92539 rlm      CALL  linux_time(0x7fffffffdf38)
