[Bug 17988] New: some frameworks fail to initialize if fs mounted in noexec

http://bugs.winehq.org/show_bug.cgi?id=17988

Summary: some frameworks fail to initialize if fs mounted in
                    noexec
           Product: Wine
           Version: 1.1.18
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

While mounting /home in noexec is common security practise i surprised not to
find similar report entries however i sure that there are a lot bugs connected
to this issue.

Practising such way myself i found out that if the place where external (not
wine-native) libraries and frameworks (such Mono or MS Visual C++) is situated
(9/10 chance that it is your /home) mounted with noexec option any tries to run
software dependent on them will fail with different and non-intuitive errors
like infamous "err:module:attach_process_dlls "MSVCR80.dll" failed to
initialize, aborting"

it's not matter what mounting options used on fs where actual application is
placed.

to pin-point such behaviour always check if non-working software will work then
you remount fs with exec option and it probably be good thing to tag existing
bug entries where bugs caused by this and named by application as duplicats to
this entry

Wine won't execute binaries from FS mounted with noexec. This is by design.

i'm not talking about "executing binaries".
i talking about loading libraries from fs with noexec.

most of libraries have no complains about fs being noexec (the ones you put in
system32)

for example: i have "The Witcher" and "No one lives forver" installations on
/media/games with exec
and /home with noexec
witcher.exe is not working, nolf.exe is okay.
then /home is exec - witcher.exe working too.

same with d3dx9_34.dll consumers which has no problems to load d3dx9_34.dll but
have troubles with MSVCR80.dll

is it not a bug ?

i mean installations is in /media/games but libraries in /home

All libraries have executable code. If reinforced no code can be executed from
libraries that came from system mounted with noexec.

It's of course more complicated then that but it's all outside of what Wine can
do. If you want to run a program under Wine no part of it can reside on a mount
mounted with noexec option.

it's really not good how .net holes become linux holes.
especially since how it selectively works...

workaround for this would be to have ~/.wine bind-mounted somethere with exec
or WINEPREFIX-it somethere.

anyway - it is still an issue unless wine will behave similar in all error
cases caused by noexec at least. ( warning message ? something ? )
that's why i will mark it as duplicate of #11661
