From: "Alexander V. Chernikov" <melif...@freebsd.org> should be handled as errors. Historically receive buffer overflows have been ignored and programs could not tell if they missed messages or messages had been truncated because of overflows. Since programs historically do not expect to get receive overflow errors, this behavior is not the default.
This is really really important for programs that use route(4) to keep in sync with the system. If we loose a message then we need to reload the full system state, otherwise the behaviour from that point is undefined and can lead to chasing bogus bug reports. --- newlib/libc/sys/rtems/include/sys/socket.h | 1 + 1 file changed, 1 insertion(+) diff --git a/newlib/libc/sys/rtems/include/sys/socket.h b/newlib/libc/sys/rtems/include/sys/socket.h index 4079b3e91..54cd0be93 100644 --- a/newlib/libc/sys/rtems/include/sys/socket.h +++ b/newlib/libc/sys/rtems/include/sys/socket.h @@ -139,6 +139,7 @@ typedef __uintptr_t uintptr_t; #define SO_NO_OFFLOAD 0x00004000 /* socket cannot be offloaded */ #define SO_NO_DDP 0x00008000 /* disable direct data placement */ #define SO_REUSEPORT_LB 0x00010000 /* reuse with load balancing */ +#define SO_RERROR 0x00020000 /* keep track of receive errors */ /* * Additional options, not kept in so_options. -- 2.35.3 _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
