Microkernel architecture with enhanced reliability and security

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• receive, by a microkernel from an application, a first system call requesting to communicate with a service registry, the first system call being associated with an operation request, wherein the service registry is located in a user space separate from a kernel space, and wherein the microkernel is located in the kernel space separate from the user space;
• send, by the microkernel in response to the first system call, a first instruction to the service registry;
• receive, by the microkernel from the service registry in response to sending the first instruction to the service registry, a second system call requesting to communicate with at least one of an application service or a protocol service, the second system call being associated with the operation request, wherein the application service and the protocol service are both located in the user space;
• send, by the microkernel in response to the second system call, a second instruction to at least one of the application service or the protocol service;
• receive, by the microkernel from at least one of the application service or the protocol service in response to sending the second instruction to the at least one of the application service or the protocol service, a third system call requesting to communicate with a driver service, the third system call being associated with the operation request, wherein the driver service is located in the user space;
• and
• send, by the microkernel in response to the third system call, a third instruction to the driver service.

A system comprising:

• one or more processors;
• and a non-transitory memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:
• receive, by a microkernel from an application, a first system call requesting to communicate with a service registry, the first system call being associated with an operation request, wherein the service registry is located in a user space separate from a kernel space, and wherein the microkernel is located in the kernel space separate from the user space;
• send, by the microkernel in response to the first system call, a first instruction to the service registry;
• receive, by the microkernel from the service registry in response to sending the first instruction to the service registry, a second system call requesting to communicate with at least one of an application service or a protocol service, the second system call being associated with the operation request, wherein the application service and the protocol service are both located in the user space;
• send, by the microkernel in response to the second system call, a second instruction to at least one of the application service or the protocol service;
• receive, by the microkernel from at least one of the application service or the protocol service in response to sending the second instruction to the at least one of the application service or the protocol service, a third system call requesting to communicate with a driver service, the third system call being associated with the operation request, wherein the driver service is located in the user space;
• and
• send, by the microkernel in response to the third system call, a third instruction to the driver service.
