An executable file using the ELF file format consists of an ELF header,
followed by a program header table or a section header table, or both.
The ELF header is always at offset zero of the file.
The program header
table and the section header table's offset in the file are defined in the
ELF header.
The two tables describe the rest of the particularities of
the file.
Improve macros used in 2.71 to convert from "mdoc" to "man".

elf.5: Document PN_XNUM extension In linux-2.6.34-rc1, an ELF core extension was added; user-land tools manipulating ELF core dump such as gdb and binutils has already been modified before; so elf.5 needs to be modified accordingly. You can follow information on the ELF extension via the LKML post: http://lkml.org/lkml/2010/1/3/103 Date Mon, 04 Jan 2010 10:06:07 +0900 (JST) Subject [RESEND][mmotm][PATCH v2, 0/5] elf coredump: Add extended numbering support This Linux-specific extension was added in kernel 2.6.34.

You can get away with "\\" in a context where no macro expansion is taking place, but try to spell a literal backslash this way in the argument to a macro and you will likely be unhappy with results. Try viewing the attached file with "man -l". "\e" is the preferred and portable way to get a portable "escape literal" going back to CSTR #54, the original Bell Labs troff paper. groff(7) discusses the issue: \\ reduces to a single backslash; useful to delay its interpretation as escape character in copy mode. For a printable backslash, use \e, or even better \[rs], to be independent from the current escape character. As of groff 1.22.4, groff_man(7) does as well: \e Widely used in man pages to represent a backslash output glyph. It works reliably as long as the .ec request is not used, which should never happen in man pages, and it is slightly more portable than the more exact ‘\(rs’ (“reverse solidus”) escape sequence. People not concerned with portability to extremely old troffs should probably just use \(rs (or \[rs]), as it means "the backslash glyph", not "the glyph corresponding to whatever the current escape character is".

Global change to many pages... Various pages use inconsistent terms for 'null byte' (which is the C99/SUSv3 term for the '\0' character). To rectify this the following changes were made in these pages: Replace 'zero byte' with 'null byte'. Replace 'null character' with 'null byte'. Replace 'nulls' with 'null bytes'. Replace 'NUL-terminated' by 'null-terminated'. Replace 'NUL' by 'null byte'. Replace 'terminating NUL' by 'terminating null byte'. Replace 'final NUL' by 'terminating null byte'. Replace 'NUL character' by 'null byte'.

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: srcfix: Remove idiosyncratic mark-up This page uses some idiosyncratic mark-up involving the use of a groff register. The mark-up actually makes no difference to the formatted result, but does cause man2html(1) to emit error messages, since it does not understand the mark-up. So, remove that mark-up.

Keep in mind that the interpretation of
.I n_type
depends on the namespace defined by the

field.

If the
.I n_namesz
field is not set (e.g., is 0), then there are two sets of notes:
one for core files and one for all other ELF types.
If the namespace is unknown, then tools will usually fallback to these sets
of notes as well.
