c# - 使用 Pinvoke 调用 AppContainer 安全功能的 UpdateProcThreadAttribute 时失败
问题描述
我正在尝试使用 C# 和 pinvoke 启动一个 appcontainer，并通过 UpdateProcThreadAttribute() 将安全功能设置到属性列表中。
GetLastError() 返回
87 - 无效参数
本文中类似的 c++ 代码（底部的 github 链接https://scorpiosoftware.net/2019/01/15/fun-with-appcontainers/）运行良好。

解决方案
感谢您的答复！我确实让这个工作。你的建议确实有帮助。这确实会在具有两个功能的应用容器中启动 notepad.exe。这是所有想要尝试这个的元帅的代码。我的目标是将我们用来保护服务器的一些程序容器化。
[StructLayout(LayoutKind.Sequential)]
public struct SECURITY_CAPABILITIES
{
public IntPtr AppContainerSid;
public IntPtr Capabilities;
public int CapabilityCount;
public int Reserved;
}
private void AddDefaultCapabilitiesSid(ref SECURITY_CAPABILITIES sc)
{
//get the size, then the sid
IntPtr mem = IntPtr.Zero;
IntPtr clientServerSid = IntPtr.Zero;
IntPtr privateNetworkSid = IntPtr.Zero;
IntPtr pSid = IntPtr.Zero;
uint cbSid = 0;
//get the size, then the sid
SecurityNative.CreateWellKnownSid(SecurityNative.WELL_KNOWN_SID_TYPE.WinCapabilityInternetClientServerSid, pSid, clientServerSid, ref cbSid);
clientServerSid = Marshal.AllocCoTaskMem(Convert.ToInt32(cbSid));
if (!SecurityNative.CreateWellKnownSid(SecurityNative.WELL_KNOWN_SID_TYPE.WinCapabilityInternetClientServerSid, pSid, clientServerSid, ref cbSid))
{
throw new ApplicationException($"Unable to create well known Client Server capability sid!");
}
//get the size, then the sid
SecurityNative.CreateWellKnownSid(SecurityNative.WELL_KNOWN_SID_TYPE.WinCapabilityPrivateNetworkClientServerSid, pSid, privateNetworkSid, ref cbSid);
privateNetworkSid = Marshal.AllocCoTaskMem(Convert.ToInt32(cbSid));
if (!SecurityNative.CreateWellKnownSid(SecurityNative.WELL_KNOWN_SID_TYPE.WinCapabilityPrivateNetworkClientServerSid, pSid, privateNetworkSid, ref cbSid))
{
throw new ApplicationException($"Unable to create well known Client Server capability sid!");
}
SecurityNative.SID_AND_ATTRIBUTES[] sidAndAttributes = new SecurityNative.SID_AND_ATTRIBUTES[2];
sidAndAttributes[0].Sid = clientServerSid;
sidAndAttributes[0].Attributes = SE_GROUP_ENABLED;
sidAndAttributes[1].Sid = privateNetworkSid;
sidAndAttributes[1].Attributes = SE_GROUP_ENABLED;
int arraySize = sidAndAttributes.Length;
int elemSize = Marshal.SizeOf(typeof(SecurityNative.SID_AND_ATTRIBUTES));
IntPtr result = Marshal.AllocHGlobal(elemSize * arraySize);
mem = new IntPtr(result.ToInt64());
for (int i = 0; i < arraySize; i++)
{
IntPtr ptr = new IntPtr(result.ToInt64() + elemSize * i);
Marshal.StructureToPtr(sidAndAttributes[i], ptr, false);
MemToFree.Add(ptr); //free this mem later
}
sc.Capabilities = mem;
sc.CapabilityCount = arraySize;
}
