From e33db96a14b85d2a2a414de784013637bc4e1fcc Mon Sep 17 00:00:00 2001 From: Michael Haubenwallner Date: Tue, 30 Apr 2019 16:15:30 +0200 Subject: Cygwin: dll_list: query dll file id at load time NtQueryVirtualMemory for MemorySectionName does not reliable return the changed dll file name when another process does move the file around, and we may end up creating forkable hardlinks to wrong dll files. So query the file id when loading the dll rather than before fork. --- winsup/cygwin/dll_init.cc | 2 ++ 1 file changed, 2 insertions(+) (limited to 'winsup/cygwin/dll_init.cc') diff --git a/winsup/cygwin/dll_init.cc b/winsup/cygwin/dll_init.cc index 28f4e53a8..4ba1bd22d 100644 --- a/winsup/cygwin/dll_init.cc +++ b/winsup/cygwin/dll_init.cc @@ -380,6 +380,8 @@ dll_list::alloc (HINSTANCE h, per_process *p, dll_type type) d->forkable_ntname = d->ntname + ntnamelen + 1; *d->forkable_ntname = L'\0'; } + if (forkables_supported ()) + d->stat_real_file_once (); /* uses nt_max_path_buf () */ append (d); if (type == DLL_LOAD) loaded_dlls++; -- cgit v1.2.3
