[Bug 50622] New: wldap32 calls Linux libraries with wrong conventions
https://bugs.winehq.org/show_bug.cgi?id=50622 Bug ID: 50622 Summary: wldap32 calls Linux libraries with wrong conventions Product: Wine Version: 6.0-rc6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wldap32 Assignee: wine-bugs(a)winehq.org Reporter: gmascellani(a)codeweavers.com Distribution: --- The code generated by dlls/wldap32/ber.c calls liblber with wrong calling conventions. For example, looking at the object disassembly I see stuff like: 1d5bf: 48 8d 54 24 26 lea 0x26(%rsp),%rdx 1d5c4: 48 89 d9 mov %rbx,%rcx 1d5c7: e8 e4 9c ff ff callq 172b0 <ber_printf(a)plt> Clearly it is trying to call the Linux ber_printf with Microsoft calling conventions (while liblber expects SYSV calling conventions, using RDI, RSI and such). This causes adsldp tests to fail on my computer, in a 64-only Wine build: ../../../../libraries/liblber/encode.c:513: ber_printf: asserzione "LBER_VALID( ber )" non riuscita. wine: Assertion failed at address 00007FAF632F8CE1 (thread 0024), starting debugger... 185335.931000:00f8:00fc:trace:gio:dlls/ntdll/unix/loader.c:1463:dump_argv Starting command winedbg --auto 32 132 Unhandled exception: assertion failed in 64-bit code (0x00007faf632f8ce1).

https://bugs.winehq.org/show_bug.cgi?id=50622 --- Comment #1 from Hans Leidekker <hans(a)meelstraat.net> --- We're using Windows headers where we should be using Unix headers. The problem with including both is that there will be many conflicts. We could solve that with preprocessor tricks like we do for winsock, but that isn't pretty. Perhaps we can avoid that by splitting this dll in Unix and PE parts, if we want to go that way? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=50622 --- Comment #2 from Giovanni Mascellani <gmascellani(a)codeweavers.com> --- BTW, I forgot to mention that dlls/wldap32/page.c also calls (for example) ber_printf, and uses the right conventions. Correspondingly it has different headers. I tried to mess up with headers, but I couldn't work out a way to make it compile (except in the original configuration, which is broken anyway), then I didn't want to spend too much time on it and passed to something else. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

It also introduces conversion for berval structures, which are not compatible on 64-bit. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
