Memory efficient virtual address management for system calls

A system comprising:

• a memory;
• a processing device operatively coupled to the memory, the processing device to:
• receive a system call initiated by a first application, wherein a first parameter of the system call specifies a first memory buffer virtual address of the first application and a second parameter of the system call specifies a second memory buffer virtual address of a second application;
• translate the memory buffer virtual address of the first application to a first physical address;
• translate the memory buffer virtual address of the second application to a second physical address;
• compare the first physical address to the second physical address;
• and
• responsive to determining that the first physical address matches the second physical address, execute the system call using the second memory buffer virtual address of the second application.

A non-transitory computer-readable media storing instructions that, when executed, cause a processing device to:

• receive a system call initiated by a first application, wherein a first parameter of the system call specifies a first memory buffer virtual address of the first application and a second parameter of the system call specifies a second memory buffer virtual address of a second application;
• translate the memory buffer virtual address of the first application to a first physical address;
• translate the memory buffer virtual address of the second application to a second physical address;
• compare the first physical address to the second physical address;
• and
• responsive to determining that the first physical address matches the second physical address, execute the system call using the second memory buffer virtual address of the second application.
