The program header shows the segments used at run time, whereas the section header lists the set of sections That is, only the executable to be debugged needs to be resident on the target system (target), while the source code and a copy of the binary file to be debugged reside on the. In computing, the executable and linkable format[3] (elf, formerly named extensible linking format) is a common standard file format for executable files, object code, shared libraries, device drivers, and core dumps

When the kernel detects a problem, it kills any offending processes and prints an oops message, which linux kernel engineers can use in debugging the condition that created the oops and fixing the underlying programming error.
The unix kernel maintains internal consistency and runtime correctness with assertions as the fault detection mechanism The basic assumption is that the hardware and the software should perform correctly and a failure of an assertion results in a panic, i.e A voluntary halt to all system activity [5] the kernel panic was introduced in an early version of unix and demonstrated a major.
Kdump is a feature of the linux kernel that creates crash dumps in the event of a kernel crash When triggered, kdump exports a memory image (also known as vmcore) that can be analyzed for the purposes of debugging and determining the cause of a crash The dumped image of main memory, exported as an executable and linkable format (elf) object, can be accessed either directly through /proc. [3] it detects problems in a program while letting it run and allows users to examine different registers.
Gdbserver is a computer program that makes it possible to remotely debug other programs
[1] running on the same system as the program to be debugged, it allows the gnu debugger to connect from another system
