Michael Kerrisk 1a212a018f execve.2: Remove unneeded ".sh" extension in interpreter script example
See https://bugzilla.kernel.org/show_bug.cgi?id=84701

As noted by C. Alex North-Keys:

1) Command name extensions considered harmful: Adding ".sh", or
any other unneeded extension, unnecessarily duplicates meta
information already present in the interpreter directive,
exposing an implementation detail that then ends up explicitly
part of other programs running this one.  Later, when such a
script is replaced with a new version in Python, C, etc., the
useless ".sh" has to be retained to avoid breaking those other
programs' calls to this one, and now has a stark antifunction
of lying about the script's content and occasionally causing
admins to run undefined experiments as root (like
"bash -x ./reallyperlscript.sh"). Such extensions, while fine
in DOS which ignores extensions explicitly, is a serious flaw
in Unix-targeted script writing.  Canonical documentation
from the Linux manual should not support such a flawed idiom -
recommending against it would be preferred.

A more extensive rant against them can be found at:
http://www.talisman.org/~erlkonig/documents/commandname-extensions-considered-harmful

2) The space after "#!" in the interpreter directive is minor -
and the kernel's fs/binfmt_script.c specifically allows for it -
but versions of unix have length limits from ~30 characters to
Linux's 127 or so (if that number's correct) so the space does
have a cost.  Most scripts I've seen lack that space, and
there's no real reason to encourage it.

Peter LaDow 0c42642f86 execve: Add envp to the Linux notes about NULL pointers
During the review of static analysis results, we discovered a
functional, but non-portable, use of execve().  For example:

    char *cmd[] = { "/path/to/some/file", NULL };
    execve(cmd[0], cmd, NULL);

The call succeeds.  Yet, the static analysis tool (rightly)
pointed out that envp could be dereferenced.  But digging into
glibc and the kernel, it appears that like argv, envp when NULL
is treated as if it were an empty list.

So, to clear things up, I'm submitting this patch to update the
man page to indicate that envp is treated like argv.

See http://bugzilla.kernel.org/show_bug.cgi?id=13569

As noted by Andrey:
The purpose of the assert macro, defined in <assert.h>,
is to provide a tool to check for programming mistakes
or program logic errors. However, the assert macro must
never be used to perform checks for run time errors,
since, with the NDEBUG macro defined, expressions within
the assert macro invocations are not evaluated/checked
for, resulting in behavior that was not originally intended.
...
The pages affected in the core package are

execve(2)
pipe(2)
tee(2)
fmemopen(3)
mq_notify(3)
qsort(3)

no man pages, when they are added they should be in Section 2,
not 3.  Therefore fix those pages that currently refer to these

Michael Kerrisk 3a9dc9ff79 execve.2: _SC_ARG_MAX is no longer necessarily constant
POSIX.1-2001 says that the values returned by sysconf()
are constant for the life of the process.
But the fact that, since Linux 2.6.23, ARG_MAX is settable
via RLIMIT_STACK means _SC_ARG_MAX is no longer constant,
since it can change at each execve().

Michael Kerrisk f202015b45 execve.2: Linux now imposes a floor on the ARG_MAX limit
Starting with Linux 2.6.23, the ARG_MAX limit became settable via
(1/4 of) RLIMIT_STACK.  This broke ABI compatibility if RLIMIT_STACK
was set such that ARG_MAX was < 32 pages.  Document the fact that
since 2.6.25 Linux imposes a floor on ARG_MAX, so that the old limit
of 32 pages is guaranteed.

For some background on the changes to ARG_MAX in kernels 2.6.23 and
2.6.25, see:

I changed your "current" to "calling" (to be consistent with the 
rest of the page), but otherwise applied as you suggest.

The revision will appear in man-pages-2.03, which I can release
