[Bug 49543] New: Several games require bcrypt DH support

https://bugs.winehq.org/show_bug.cgi?id=49543 Bug ID: 49543 Summary: Several games require bcrypt DH support Product: Wine Version: 5.12 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: bcrypt Assignee: wine-bugs(a)winehq.org Reporter: bshanks(a)codeweavers.com Distribution: --- There are a few games that need DH support in bcrypt. - The Rockstar Games Launcher, GTA V, and RDR 2 all open DH and generate+export a public key. With DH unimplemented, the only effect I know of is that RDR 2's online mode fails to load. - Astroneer dedicated server (see https://www.reddit.com/r/wine_gaming/comments/gvaa9a/bcryptopenalgorithmpro…) >From a disassembler, it looks like the server imports/exports public/private keys, and uses BCryptDeriveKey() with the "HASH" KDF and SHA256. Microsoft has sample code which tests (some of) the functionality: https://github.com/microsoft/Windows-classic-samples/blob/master/Samples/Se… Unfortunately GnuTLS doesn't currently export the needed functionality. There's an issue open: https://gitlab.com/gnutls/gnutls/-/issues/894 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 48175] New: AION (64 bit) - crashes in CrySystem32.dll.CryFree() due to high memory pointers allocated

https://bugs.winehq.org/show_bug.cgi?id=48175 Bug ID: 48175 Summary: AION (64 bit) - crashes in CrySystem32.dll.CryFree() due to high memory pointers allocated Product: Wine Version: 4.20 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: gofmanp(a)gmail.com Distribution: --- Created attachment 65809 --> https://bugs.winehq.org/attachment.cgi?id=65809 Force down-top memory allocation Split off from bug #40334. The crash happens after the original issue in Bug #40334 is solved, after the loading screen or very soon after login. The game expects memory pointers from HeapAlloc and VirtualAlloc to fit in the certain range. It is fine with ~16GB range as per my observations, that is, up to 0x3ffffffff address. I am attaching the patch which is confirmed to fix the issue with AION. The patch consists of two, the first one is not exactly related but the second one depends on it. At the present moment the first one is passing the review upstream. The solution in the second patch is to force virtual memory allocation return lower addresses when they are available (unless top-down allocation is explicitly requested), that's how it seem to work on Windows. The patch does it essentially the same way as the allocation with zero_bits mask is performed. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
