* Drop max_sys_priv wincapCorinna Vinschen2016-06-241-60/+65
| | | | | | | | | | | Convert sys_privs to const struct with TOKEN_PRIVILEGES layout. Drop function get_system_priv_list. Just use pointer to sys_privs. Dropping max_sys_priv from wincaps requires to make sure that the bitfield is 8 byte aligned on x86_64, otherwise gcc (5.3 only?) apparently breaks access to the bitfield (off by 4 bytes).

* Overwite potentially faked kernel version with correct valuesCorinna Vinschen2016-03-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | * ntdll.h (RtlGetNtVersionNumbers): Declare. * wincap.cc (wincapc::init): Overwrite kernel version info returned by RtlGetVersion with correct info returnd by RtlGetNtVersionNumbers. Add comment. Originally, using RtlGetVersion instead of GetVersionEx was supposed to fix the fact that GetVersionInfo returns the wrong kernel version if the executable has been built with an old manifest (or none at all), starting with Windows 8.1. Either this never really worked as desired and our testing was flawed, or this has been changed again with Windows 10, so that RtlGetVersion does the kernel faking twist as well. Since we're only reading the value in the first process in a process tree. the entire process tree is running with a wrong OS version information in that case. Fortunately, the (undocumented) RtlGetNtVersionNumbers function is not affected by this nonsense, so we simply override the OS version info fields with the correct values now.

(create_token): Explicitely set auth_luid to ANONYMOUS_LOGON_LUID or LOCALSERVICE_LUID depending on OS. Explain why. Remove handling of logon SID since we don't generate one anymore.

* Don't use LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32). It hangsCorinna Vinschen2016-01-271-7/+0
| | | | | | | | | | | | | | | | Observed running hexchat under X. For some reason the call to LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32) in dll_load hangs when trying to autoload MsgWaitForMultipleObjectsEx in select.cc after hexchat forks to run DNS calls. Dropping the call and just using full paths as in 2.3.1 fixes the issue. * autoload.cc (dll_load): Drop call to LoadLibraryEx with LOAD_LIBRARY_SEARCH_SYSTEM32 flag. * wincap.h (wincaps::has_load_lib_search_flags): Remove. * wincap.cc (wincaps::has_load_lib_search_flags): Drop handling this flag.

* Always allocate main thread stack from pthread stack area on x86_64.Corinna Vinschen2015-12-071-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | * dcrt0.cc: Semi-revert commit 12743c2d5d2721f3a80b4d7671a349be03c1f520. (dll_crt0_0): Drop setting wow64_needs_stack_adjustment on 64 bit. (_dll_crt0): Split out 64 bit code again and always create new main thread stack, unless forked off from the non main thread in the parent. Call create_new_main_thread_stack with parent stack commitsize if started from the parent's main thread. Only call child_info_fork::alloc_stack for the latter case on 64 bit. Slightly rearrange moving rsp and rbp to new stack and document how. Revert 32 bit wow64 handling to its former self. * miscfunc.cc (create_new_main_thread_stack): Take a commitsize parameter and use it if it's not 0. Don't set _main_tls here, it's done in the caller _dll_crt0 anyway. Return stackbase - 16 bytes, rather than stacklimit (which was very wrong anyway). * miscfuncs.h (create_new_main_thread_stack): Accommodate declaration to aforementioned change. * wincap.h (wincaps::has_3264_stack_broken): Remove element. * wincap.cc: Ditto, throughout. * wow64.cc: Semi-revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520 but keep architecture-agnostic type changes intact.
