The linux 4.3 s390 kernel has separate system calls that were originally hidden behind the socketcall multiplexer system call. Newer glibc versions will use these direct system calls instead of socketcall when available. Causing several regtest failures. The new "unwrapped" syscalls are: #define __NR_recvmmsg 357 #define __NR_sendmmsg 358 #define __NR_socket 359 #define __NR_socketpair 360 #define __NR_bind 361 #define __NR_connect 362 #define __NR_listen 363 #define __NR_accept4 364 #define __NR_getsockopt 365 #define __NR_setsockopt 366 #define __NR_getsockname 367 #define __NR_getpeername 368 #define __NR_sendto 369 #define __NR_sendmsg 370 #define __NR_recvfrom 371 #define __NR_recvmsg 372 #define __NR_shutdown 373 Reproducible: Always
Created attachment 97376 [details] S390 Split Socketcall Proposed patch. Simply wires up the split out system calls directly to the existing syswrap handlers.
The patch fixes the following s390 regtest errors: memcheck/tests/buflen_check (stderr) memcheck/tests/null_socket (stderr) memcheck/tests/sendmsg (stderr) none/tests/fcntl_setown (stderr) none/tests/fdleak_cmsg (stderr) none/tests/fdleak_ipv4 (stdout) none/tests/fdleak_ipv4 (stderr) none/tests/fdleak_socketpair (stderr) none/tests/syslog (stderr) Committed as valgrind svn r15802.
