Fixes bugs 5573 and 3619. http://bugs.winehq.org/show_bug.cgi?id=5573 http://bugs.winehq.org/show_bug.cgi?id=3619 Changelog: * Always return ERROR_SUCCESS in WinVerifyTrust. dlls/wintrust/wintrust_main.c | 18 +- 1 files changed, 5 insertions(+), 13 deletions(-) When I run process explorer without tracing/debugging everything is fine. As soon as I add +wintrust,+heap it fails again. There is most likely some heap corruption somewhere (couldn't be more vague). Alexandre's patch to add more free list entries only masked the problem, as far as I can see from the results. Cheers and sorry for the misleading remarks, Paul.

Cheers and sorry for the misleading remarks, Can you explain your comment, Process Explorer expects a correct implementation concerning WinVerifyTrust? When it calls WinVerifyTrust and we return ERROR_SUCCESS, what does it do with that information that causes the application to fail? Even if we took the time to implement WinVerifyTrust, we would still return ERROR_SUCCESS and the situation wouldn't be any different. In the meantime, several installers are hanging up because of this. -- James Hawkins

Even if we took the time to implement WinVerifyTrust, we would still return ERROR_SUCCESS and the situation wouldn't be any different. In the meantime, several installers are hanging up because of this. It just turned out (and that makes sense of course) that when returning a real error Process Explorer uses a different code path. The calls PE uses are: CryptCATAdminAcquireContext (stubbed) CryptCATAdminCalcHashFromFileHandle (stubbed) CryptCATAdminReleaseContext (stubbed) and then WinVerifyTrust (stubbed as well). Before Alexandre's patch it always failed when returning ERROR_SUCCESS, now it only fails when extra debugging is added. I have no clue (yet) where the heap corruption comes from. I can live btw with a default of ERROR_SUCCESS as that will work (100% ?) when run as an ordinary user. There is however something fishy going on. Cheers, Paul.
