From 0ba3199915e456580a423fcbe9a10970d8063eaf Mon Sep 17 00:00:00 2001 From: Justine Tunney Date: Sun, 23 Jul 2023 16:31:10 -0700 Subject: [PATCH] Fix some more socket bugs - The functions that return a sockaddr now do so the same way the Linux Kernel does across platforms, e.g. getpeername(), accept4() - Socket system calls on Windows will now only check for interrupts when a blocking operation needs to be performed. - Write tests for recvfrom() system call --- libc/sock/accept-nt.c | 38 ++-------- libc/sock/accept4-sysv.c | 22 +++--- libc/sock/accept4.c | 24 ++++--- libc/sock/getpeername-nt.c | 35 --------- libc/sock/getpeername-sysv.c | 36 ---------- libc/sock/getsockname-nt.c | 33 --------- libc/sock/getsockname-sysv.c | 36 ---------- libc/sock/getsockname.c | 73 ++++++++++++++----- libc/sock/internal.h | 2 +- libc/sock/recv-nt.c | 3 +- libc/sock/recvfrom-nt.c | 3 +- libc/sock/recvfrom.c | 37 ++++------ libc/sock/send-nt.c | 3 +- libc/sock/sendto-nt.c | 1 - libc/sock/{getpeername.c => sockaddr.c} | 78 +++++++++++++------- libc/sock/sockaddr2bsd.c | 2 + libc/sock/sockaddr2linux.c | 2 + libc/sock/struct/sockaddr.internal.h | 5 ++ libc/sock/syscall_fd.internal.h | 3 +- libc/sock/wsablock.c | 2 +- libc/sysv/consts.sh | 42 +++++------ libc/sysv/consts/MSG_DONTWAIT.S | 2 +- libc/sysv/consts/SIOCADDMULTI.S | 2 +- libc/sysv/consts/SIOCDELMULTI.S | 2 +- libc/sysv/consts/SIOCDIFADDR.S | 2 +- libc/sysv/consts/SIOCGIFADDR.S | 2 +- libc/sysv/consts/SIOCGIFBRDADDR.S | 2 +- libc/sysv/consts/SIOCGIFCONF.S | 2 +- libc/sysv/consts/SIOCGIFDSTADDR.S | 2 +- libc/sysv/consts/SIOCGIFFLAGS.S | 2 +- libc/sysv/consts/SIOCGIFMETRIC.S | 2 +- libc/sysv/consts/SIOCGIFMTU.S | 2 +- libc/sysv/consts/SIOCGIFNETMASK.S | 2 +- libc/sysv/consts/SIOCGPGRP.S | 2 +- libc/sysv/consts/SIOCSIFADDR.S | 2 +- libc/sysv/consts/SIOCSIFBRDADDR.S | 2 +- libc/sysv/consts/SIOCSIFDSTADDR.S | 2 +- libc/sysv/consts/SIOCSIFFLAGS.S | 2 +- libc/sysv/consts/SIOCSIFMETRIC.S | 2 +- libc/sysv/consts/SIOCSIFMTU.S | 2 +- libc/sysv/consts/SIOCSIFNETMASK.S | 2 +- libc/sysv/consts/SIOCSPGRP.S | 2 +- libc/sysv/consts/msg.h | 35 ++------- test/libc/calls/ioctl_test.c | 3 +- test/libc/sock/recvfrom_test.c | 94 +++++++++++++++++++++++++ test/libc/sock/sendfile_test.c | 2 + test/libc/sock/socket_test.c | 27 +++++++ test/libc/sock/test.mk | 10 ++- test/libc/sock/unix_test.c | 6 +- 49 files changed, 347 insertions(+), 352 deletions(-) delete mode 100644 libc/sock/getpeername-nt.c delete mode 100644 libc/sock/getpeername-sysv.c delete mode 100644 libc/sock/getsockname-nt.c delete mode 100644 libc/sock/getsockname-sysv.c rename libc/sock/{getpeername.c => sockaddr.c} (51%) create mode 100644 test/libc/sock/recvfrom_test.c diff --git a/libc/sock/accept-nt.c b/libc/sock/accept-nt.c index 047ff96b6..2be018140 100644 --- a/libc/sock/accept-nt.c +++ b/libc/sock/accept-nt.c @@ -18,13 +18,12 @@ ╚─────────────────────────────────────────────────────────────────────────────*/ #include "libc/calls/internal.h" #include "libc/calls/state.internal.h" +#include "libc/errno.h" #include "libc/macros.internal.h" #include "libc/mem/mem.h" #include "libc/nt/winsock.h" #include "libc/sock/internal.h" #include "libc/sock/struct/sockaddr.h" -#include "libc/sock/struct/sockaddr.internal.h" -#include "libc/sock/struct/sockaddr6.h" #include "libc/sock/syscall_fd.internal.h" #include "libc/str/str.h" #include "libc/sysv/consts/af.h" @@ -32,7 +31,7 @@ #include "libc/sysv/consts/sock.h" union AcceptExAddr { - union sockaddr_storage_linux addr;
