elf(5): document notes
...
Document the Elf{32,64}_Nhdr structure, the sections/segments that
contain notes, and how to interpret them. I've been lazy and only
included the GNU extensions here, especially as others are not
defined in the elf.h header file as shipped by glibc.
I've mostly used binutils, glibc, breakpad, and the GABI ELF spec
as sources of data for these fields.

elf(5): Add subsection headers at major points
...
The current pages dumps all the content into one big DESCRIPTION
with no real visual break up between logically independent
sections. Add some subsection headers to make it easier to
read and scan.

elf.5: Fix description of STV_PROTECTED
...
Quoting Mike:
gabi says:
https://refspecs.linuxbase.org/elf/gabi4+/ch4.symtab.html
A symbol defined in the current component is protected if it is
visible in other components but not preemptable, meaning that
any reference to such a symbol from within the defining component
must be resolved to the definition in that component, even if
there is a definition in another component that would preempt by
the default rules. A symbol with STB_LOCAL binding may not have
STV_PROTECTED visibility. If a symbol definition with
STV_PROTECTED visibility from a shared object is taken as
resolving a reference from an executable or another shared object,
the SHN_UNDEF symbol table entry created has STV_DEFAULT
visibility.
solaris/oracle says:
https://docs.oracle.com/cd/E26502_01/html/E26507/chapter6-79797.html
A symbol that is defined in the current component is protected
if the symbol is visible in other components, but cannot be
preempted. Any reference to such a symbol from within the defining
component must be resolved to the definition in that component.
This resolution must occur, even if a symbol definition exists in
another component that would interpose by the default rules.
A symbol with STB_LOCAL binding will not have STV_PROTECTED
visibility.
but i think this ibm article is probably the most understandable:
https://www.ibm.com/developerworks/aix/library/au-aix-symbol-visibility/
The symbol is visible outside the current executable or shared
object, but it may not be overridden. In other words, if a
protected symbol in a shared library is referenced by an other
code in the shared library, the other code will always reference
the symbol in the shared library, even if the executable defines
a symbol with the same name.

elf.5: Add byte positions for all EI_xxx fields
...
When describing e_ident, most of the EI_xxx defines mention the
exact byte number. This is useful when manually hacking an ELF
with a hex editor. However, the last few fields don't do this,
which means you have to count things up yourself.
Add a single word to each so you don't have to do that.
