Catching memory defects in the kernel – comparisons and notes (Part 2)

The table that follows is an extension of the one in the previous chapter (Table 5.5), adding the rightmost column, that of employing the kernel's SLUB debug framework. Here, we tabulate and hence summarize our test case results for our test runs with all the tooling technologies/kernels – vanilla/distro kernel, compiler warnings, with KASAN, with UBSAN, and with SLUB debug with our debug kernel – we employed in the preceding and this chapter. In effect, it's a compilation of all the findings in one place, thus allowing you to make quick (and hopefully helpful) comparisons.

Table 6.4 – Summary of various common memory defects and how various technologies react in catching them (or not)

As mentioned in the previous chapter, an explanation of the footnotes within this table (such as [C1], [K1], [U1], and so on) can be found in earlier...
