From: Rose Hellsing <rose@pinkro.se> These functions create LPC (Local Procedure Call) ports for inter-process communication. NtCreatePort creates a regular port while NtCreateWaitablePort creates a port that can be waited on using WaitForSingleObject. --- dlls/ntdll/ntdll.spec | 4 +-- dlls/ntdll/signal_arm64ec.c | 1 + dlls/ntdll/unix/sync.c | 61 +++++++++++++++++++++++++++++++++++-- dlls/wow64/sync.c | 22 +++++++++++++ include/winternl.h | 1 + 5 files changed, 85 insertions(+), 4 deletions(-) diff --git a/dlls/ntdll/ntdll.spec b/dlls/ntdll/ntdll.spec index 0b6d9b2cbf4..24d6dc99f2b 100644 --- a/dlls/ntdll/ntdll.spec +++ b/dlls/ntdll/ntdll.spec @@ -212,7 +212,7 @@ @ stdcall -syscall NtCreateToken(ptr long ptr long ptr ptr ptr ptr ptr ptr ptr ptr ptr) @ stdcall -syscall NtCreateTransaction(ptr long ptr ptr long long long long ptr ptr) @ stdcall -syscall NtCreateUserProcess(ptr ptr long long ptr ptr long long ptr ptr ptr) -# @ stub NtCreateWaitablePort +@ stdcall -syscall NtCreateWaitablePort(ptr ptr long long long) @ stdcall -arch=i386 NtCurrentTeb() @ stdcall -syscall NtDebugActiveProcess(long long) @ stdcall -syscall NtDebugContinue(long ptr long) @@ -1292,7 +1292,7 @@ @ stdcall -private ZwCreateToken(ptr long ptr long ptr ptr ptr ptr ptr ptr ptr ptr ptr) NtCreateToken @ stdcall -private ZwCreateTransaction(ptr long ptr ptr long long long long ptr ptr) NtCreateTransaction @ stdcall -private ZwCreateUserProcess(ptr ptr long long ptr ptr long long ptr ptr ptr) NtCreateUserProcess -# @ stub ZwCreateWaitablePort +@ stdcall -private ZwCreateWaitablePort(ptr ptr long long long) NtCreateWaitablePort @ stdcall -private ZwDebugActiveProcess(long long) NtDebugActiveProcess @ stdcall -private ZwDebugContinue(long ptr long) NtDebugContinue @ stdcall -private ZwDelayExecution(long ptr) NtDelayExecution diff --git a/dlls/ntdll/signal_arm64ec.c b/dlls/ntdll/signal_arm64ec.c index baee1f23722..2bd6014fdb2 100644 --- a/dlls/ntdll/signal_arm64ec.c +++ b/dlls/ntdll/signal_arm64ec.c @@ -415,6 +415,7 @@ DEFINE_SYSCALL(NtCreateTimer, (HANDLE *handle, ACCESS_MASK access, const OBJECT_ DEFINE_SYSCALL(NtCreateToken, (HANDLE *handle, ACCESS_MASK access, OBJECT_ATTRIBUTES *attr, TOKEN_TYPE type, LUID *token_id, LARGE_INTEGER *expire, TOKEN_USER *user, TOKEN_GROUPS *groups, TOKEN_PRIVILEGES *privs, TOKEN_OWNER *owner, TOKEN_PRIMARY_GROUP *group, TOKEN_DEFAULT_DACL *dacl, TOKEN_SOURCE *source)) DEFINE_SYSCALL(NtCreateTransaction, (HANDLE *handle, ACCESS_MASK mask, OBJECT_ATTRIBUTES *obj_attr, GUID *guid, HANDLE tm, ULONG options, ULONG isol_level, ULONG isol_flags, PLARGE_INTEGER timeout, UNICODE_STRING *description)) DEFINE_SYSCALL(NtCreateUserProcess, (HANDLE *process_handle_ptr, HANDLE *thread_handle_ptr, ACCESS_MASK process_access, ACCESS_MASK thread_access, OBJECT_ATTRIBUTES *process_attr, OBJECT_ATTRIBUTES *thread_attr, ULONG process_flags, ULONG thread_flags, RTL_USER_PROCESS_PARAMETERS *params, PS_CREATE_INFO *info, PS_ATTRIBUTE_LIST *ps_attr)) +DEFINE_SYSCALL(NtCreateWaitablePort, (HANDLE *handle, OBJECT_ATTRIBUTES *attr, ULONG info_lon, ULONG data_len, ULONG reserved)) DEFINE_SYSCALL(NtDebugActiveProcess, (HANDLE process, HANDLE debug)) DEFINE_SYSCALL(NtDebugContinue, (HANDLE handle, CLIENT_ID *client, NTSTATUS status)) DEFINE_SYSCALL(NtDelayExecution, (BOOLEAN alertable, const LARGE_INTEGER *timeout)) diff --git a/dlls/ntdll/unix/sync.c b/dlls/ntdll/unix/sync.c index fbf054e9d93..ede54e5944c 100644 --- a/dlls/ntdll/unix/sync.c +++ b/dlls/ntdll/unix/sync.c @@ -3061,14 +3061,71 @@ NTSTATUS WINAPI NtOpenSection( HANDLE *handle, ACCESS_MASK access, const OBJECT_ } +/* LPC port access rights */ +#define PORT_CONNECT 0x0001 +#define PORT_ALL_ACCESS (STANDARD_RIGHTS_REQUIRED | SYNCHRONIZE | PORT_CONNECT) + /*********************************************************************** * NtCreatePort (NTDLL.@) */ NTSTATUS WINAPI NtCreatePort( HANDLE *handle, OBJECT_ATTRIBUTES *attr, ULONG info_len, ULONG data_len, ULONG *reserved ) { - FIXME( "(%p,%p,%u,%u,%p),stub!\n", handle, attr, info_len, data_len, reserved );
