From cdb4231369f4c06795e170f9cb003d8de1581f5b Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Sun, 15 May 2011 18:49:40 +0000 Subject: * cygwin.din (pthread_attr_getguardsize): Export. (pthread_attr_setguardsize): Export. (pthread_attr_setstack): Export. (pthread_attr_setstackaddr): Export. * init.cc (dll_entry): Remove wow64_test_stack_marker. Check for unusual stack address by testing stack addresses from current TEB. Check validity of _my_tls by testing if it's within the stack as given in current TEB. * miscfuncs.cc (struct thread_wrapper_arg): New structure used to push all required information to thread_wrapper function. (thread_wrapper): Wrapper function for actual thread function. If an application stack has been given, change %ebp and %esp so that the thread function runs on that stack. If the thread has been created by CygwinCreateThread, set up the POSIX guard pages if necessary. (CygwinCreateThread): New function. * miscfuncs.h (CygwinCreateThread): Declare. * ntdll.h (struct _TEB): Define all members up to Peb. * posix.sgml (std-susv4): Move pthread_attr_getguardsize, pthread_attr_setguardsize and pthread_attr_setstack here. (std-deprec): Add pthread_attr_setstackaddr. * sysconf.cc (sca): Set _SC_THREAD_ATTR_STACKADDR to _POSIX_THREAD_ATTR_STACKADDR. * thread.cc (pthread::precreate): Copy pthread_attr stackaddr and guardsize members. (pthread::create): Call CygwinCreateThread. (pthread_attr::pthread_attr): Initialize guardsize. (pthread_attr_setstack): New function. (pthread_attr_setstackaddr): New function. (pthread_attr_setguardsize): New function. (pthread_attr_getguardsize): New function. (pthread_getattr_np): Copy attr.guardsize. * thread.h (pthread_attr): Add member guardsize. * include/pthread.h (pthread_attr_getguardsize): Declare. (pthread_attr_setguardsize): Declare. * include/cygwin/version.h: Bump API minor number. --- winsup/cygwin/ntdll.h | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'winsup/cygwin/ntdll.h') diff --git a/winsup/cygwin/ntdll.h b/winsup/cygwin/ntdll.h index cb4e6d962..9c5597ec1 100644 --- a/winsup/cygwin/ntdll.h +++ b/winsup/cygwin/ntdll.h @@ -622,11 +622,15 @@ typedef struct _PEB ULONG SessionId; } PEB, *PPEB; -/* Simplifed definition, just to get the PEB pointer. */ +/* Simplified definition, just to get the TIB and the PEB pointer. */ typedef struct _TEB { - PVOID dummy[12]; - PPEB Peb; + NT_TIB Tib; + PVOID EnvironmentPointer; + CLIENT_ID ClientId; + PVOID ActiveRpcHandle; + PVOID ThreadLocalStoragePointer; + PPEB Peb; /* A lot more follows... */ } TEB, *PTEB; @@ -1111,9 +1115,7 @@ extern "C" ULONG, ULONG *); NTSTATUS NTAPI NtQuerySystemInformation (SYSTEM_INFORMATION_CLASS, PVOID, ULONG, PULONG); - NTSTATUS WINAPI NtQuerySystemTime (PLARGE_INTEGER); - NTSTATUS NTAPI NtQuerySecurityObject (HANDLE, SECURITY_INFORMATION, PSECURITY_DESCRIPTOR, ULONG, PULONG); NTSTATUS NTAPI NtQuerySymbolicLinkObject (HANDLE, PUNICODE_STRING, PULONG); -- cgit v1.2.3
