linux-gate.so.1 is a special dynamic shared object (DSO) that is provided by the Linux kernel. It is also known as the "virtual dynamic shared object" (vdso) and is used to provide fast access to certain kernel functions from user space without the overhead of a system call.
The linux-gate.so.1 library is loaded into the address space of every process on a Linux system. It provides a number of functions that can be accessed directly from user space without the need for a system call. These functions include:
gettimeofday: This function returns the current time in seconds and microseconds.clock_gettime: This function returns the current time in a specified clock format.getcpu: This function returns the processor number and CPU time used by the calling process.Using the linux-gate.so.1 library can significantly improve the performance of certain applications that make frequent calls to these functions, as it eliminates the overhead of a system call.
The linux-gate.so.1 library is provided by the Linux kernel and is automatically loaded into the address space of every process on a Linux system. It is usually located at /lib/ld-linux.so.2 or /lib64/ld-linux-x86-64.so.2.
