17    5. Symbol table and Elf section access
35 Since apply_relocate_add() requires access to a module's section header
36 table, symbol table, and relocation section indices, Elf information is
37 preserved for livepatch modules (see section 5). Livepatch manages its own

93 relocation section(s) to the driver once it loads.
98 between a livepatch relocation section and the target section (usually the
99 text section of a function) to which the relocation(s) apply. It is
104 Since Elf information is preserved for livepatch modules (see Section 5), a
105 livepatch relocation section can be applied simply by passing in the
106 appropriate section index to apply_relocate_add(), which then uses it to
107 access the relocation section and apply the relocations.
109 Every symbol referenced by a rela in a livepatch relocation section is a
111 apply_relocate_add(). See Section 3 for more information.

132   The relocation section name is prefixed with the string ".klp.rela."
136   which the relocation section belongs follows immediately after the prefix.
139   The actual name of the section to which this relocation section applies.

206 any livepatch relocation section, all livepatch symbols referenced by that
207 section must be resolved before livepatch can call apply_relocate_add() for
208 that reloc section.
222 relocation section refer to their respective symbols with their symbol indices,

243 Livepatch symbols must have their section index marked as SHN_LIVEPATCH, so
297   Note that the 'Ndx' (Section index) for these symbols is SHN_LIVEPATCH (0xff20).

305 symbol table, and relocation section indices, Elf information is preserved for
