+Subject: [PATCH] tests: avoid accept() libc function when tracing accept()
+ syscall
+
+The libc function is allowed to implement accept() using accept4()
+syscall, so migrate to accept4() those tests that trace accept() syscall
+but do not test accept() specifically, and change the test of accept()
+syscall to invoke either __NR_accept or __NR_socketcall(SYS_ACCEPT)
+directly.
+
+* tests/accept_compat.h: Remove.
+* tests/Makefile.am (EXTRA_DIST): Remove accept_compat.h.
+* tests/accept.c [TEST_SYSCALL_NAME]: Do not invoke accept(),
+call __NR_accept or __NR_socketcall if available, or skip the test.
+* tests/net-y-unix.c: Do not include "accept_compat.h".
+(main): Invoke accept4() instead of accept().
+* tests/net-yy-inet.c: Likewise.
+* tests/net-yy-unix.c: Likewise.
+
+Resolves: https://github.com/strace/strace/issues/260
