[Mono-devel-list] [PATCH] CAS support for stack walk on p/invoke methods

[Sebastien Pouliot]

Hello,

This patch generates code to do a stack walk (Demand for
SecurityPermissionFlag.UnmanagedCode) before calling into p/invoke
method. This code only gets called if the security manager is active
(mono --security).

The [SuppressUnmanagedCodeSecurity] attribute can be used on the
p/invoke method declaration or on it's class to suppress the stack walk
(e.g. it can provide a nice performance boost if the assembly has a
[assembly: SecurityPermission (RequestMinimum, UnmanagedCode=true)]).

Tests have already been committed under
/mono/mono/tests/cas/demand/

Thanks for reviewing.
