recvmmsg is a false positive, as we set __ARCH_WANT_SYS_SOCKETCALL.
This looks really strange. The commit that introduced recvmmsg (a2e27255)
added it to both socketcall and as a separate syscall in a number of
architectures, without a good reason for it. I guess it's too late
to change that now, but we should at least fix the script so we
don't report it missing when socketcall is set.
Some architectures don't use socketcall, so they use a separate syscall.
IIRC, powerpc is migrating away from socketcall (commit
86250b9d12caa1a3dee12a7cf638b7dd70eaadb6, "powerpc: Wire up direct
socket system calls"), hence they added a separate call for it.
However, if your unistd.h has defined __NR_recvmmsg before, you should
probably add it to the syscall table, just in case that someone built
a binary with that number.
We never had it.
BTW, we have a hole at 218/219. I don't remember why, but it may have been
a placeholder for pselect6 and ppoll when that implementation was still in flux.
Couldn't find anything about it in git/cvs archives, so I'll check
have to check my
old mailing list archives...
