Hi all,
this is a patchset I announced 3 months ago [1]. I'm Cc you only in
cover letter (I don't want to fill your mailbox, the code itself is in
LTP ML [2], lore archive [3], patchwork [4]).
Kind regards,
Petr

nommu detection was written for UCLINUX distribution, which is not
active any more. While there are still some used nommu kernel
architectures (m68k and other), there is missing support in the new
C API and nobody from the community did not stand to implement and
maintain it. Therefore removing all UCLINUX/nommu related code in this
and following commits.

Replace it with MAP_PRIVATE.
It was defined only to support UCLINUX.

UCLINUX is dead and it's support has been removed from LTP.
Although Documentation/admin-guide/mm/nommu-mmap.rst still exists in
kernel tree, there is nobody really using it.

--------------
---- Intro ---
--------------
-
-Linux running on processors without a memory management unit place certain
-restrictions on the userspace programs. Here we will provide some guidelines
-for people who are not familiar with such systems.
-
-If you are not familiar with virtual memory, you might want to review some
-background such as:
- http://en.wikipedia.org/wiki/Virtual_Memory
- /usr/src/linux/Documentation/nommu-mmap.txt
-
-----------------------------
---- No memory protection ---
-----------------------------
-
-By virtue of every process getting its own virtual memory space, applications
-are protected from each other. So a bad memory access in one will not affect
-the memory of another. When processors forgo virtual memory, they typically
-do not add memory protection back in to the hardware. There are one or two
-exceptions to this rule, but for now, we'll assume no one supports it.
-
-In practical terms, this means you cannot dereference bad pointers directly
-and expect the kernel to catch and kill your application. However, you can
-expect the kernel to catch some bad pointers when given to system calls.
-
-For example, this will "work" in the sense that no signal will be sent:
- char *foo = NULL;
- foo[0] = 'a';
- foo[1] = 'b';
-
-However, the kernel should return errors when using "standard" bad pointers
-with system calls. Such as:
- char *foo = NULL;
- write(1, foo, 10);
- -> kernel will return EFAULT or similar
-The other bad pointer you can rely on in your tests is -1:
- char *foo = (void *)-1;
- read(0, foo, 10);
- -> kernel will return EFAULT or similar
-
-Otherwise, no bad pointer may reliably be tested, either directly or
-indirectly via the kernel. This tends to be a large part of the UCLINUX
-ifdef code that shows up in LTP.
-
-----------------
---- No forks ---
-----------------
-
-The ubiquitous fork() function relies completely on the Copy On Write (COW)
-functionality provided by virtual memory to share pages between processes.
-Since this isn't feasible without virtual memory, there is no fork() function.
-You will either get a linker error (undefined reference to fork) or you will
-get a runtime failure of ENOSYS.
-
-Typically, fork() is used for very few programming paradigms:
- - daemonization
- - run a program
- - parallelism
-
-For the daemonization functionality, simply use the daemon() function. This
-works under both MMU and NOMMU systems.
-
-To run a program, simply use vfork() followed by an exec-style function.
-And change the error handler in the child from exit() to _exit(). This too
-works under both MMU and NOMMU systems. But be aware of vfork() semantics --
-since the parent and child share the same memory process, the child has to be
-careful in what it does. This is why the recommended construct is simply:
- pid_t child = vfork();
- if (vfork == 0)
- _exit(execl(....));
-
-For parallelism where processes use IPC to work together, you have to options,
-neither of which are easy. You can rewrite to use threads, or you can re-exec
-yourself with special flags to pass along updated runtime state. This is what
-the self_exec() helper function in LTP is designed for.
-
--------------------------
---- No overcommitting ---
--------------------------
-
-Virtual memory allows people to do malloc(128MiB) and get back a buffer that
-big. But that buffer is only of virtual memory, not physical. On a NOMMU
-system, the memory comes immediately from physical memory and takes it away
-from anyone else.
-
-Avoid large mallocs.
-
----------------------
---- Fragmentation ---
----------------------
-
-On a MMU system, when physical memory gets fragmented, things slow down. But
-they keep working. This is because every new process gets a clean virtual
-memory address space. While processes can fragment their own virtual address
-space, this usually takes quite a long time and a lot of effort, so generally
-it is not a problem people hit.
-
-On a NOMMU system, when physical memory gets fragmented, access to large
-contiguous blocks becomes unavailable which means requests fail. Even if your
-system has 40MiB _total_ free, the largest contiguous block might only be 1MiB
-which means that allocations larger than that will always fail.
-
-Break up your large memory allocations when possible. Generally speaking,
-single allocations under 2MiB aren't a problem.
-
------------------
---- No paging ---
------------------
-
-No virtual memory means you can't mmap() a file and only have the pages read in
-(paged) on the fly. So if you use mmap() on a file, the kernel must allocate
-memory for it and read in all the contents immediately.
-
----------------------
---- No swap space ---
----------------------
-
-See the "No paging" section above. For the same reason, there is no support
-for swap partitions. Plus, nommu typically means embedded which means flash
-based storage which means limited storage space and limited number of times
-you can write it.
-
--------------------------
---- No dynamic stacks ---
--------------------------
-
-No virtual memory means that applications can't all have their stacks at the
-top of memory and allowed to grown "indefinitely" downwards. Stack space is
-fixed at process creation time (when it is first executed) and cannot grow.
-While the fixed size may be increased, it's best to avoid stack pressure in
-the first place.
-
-Avoid the alloca() function and use malloc()/free() instead.
-
-Avoid declaring large buffers on the stack. Some people like to do things
-such as:
- char buf[PATH_MAX];
-This will most likely smash the stack on nommu systems ! Use global variables
-(the bss), or use malloc()/free() type functions.
-
--------------------------------
---- No dynamic data segment ---
--------------------------------
-
-No virtual memory means that mappings cannot arbitrarily be extended. Another
-process might have its own mapping right after yours! This is where the brk()
-and sbrk() functions come into play. These are most often used to dynamically
-increase the heap space via the C library, but a few people use these manually.
-
-Best if you simply avoid them, and if you're writing tests to exercise these
-functions specifically, make them nops/XFAIL for nommu systems.
-
--------------------------------
---- Limited shared mappings ---
--------------------------------
-
-No virtual memory means files cannot be mmapped in and have writes to it
-written back out to disk on the fly. So you cannot use MAP_SHARED when
-mmapping a file.
-
--------------------------
---- No fixed mappings ---
--------------------------
-
-The MAP_FIXED option to mmap() is not supported. It doesn't even really work
-all that well under MMU systems.
-
-Best if you simply avoid it, and if you're writing tests to exercise this
-option specifically, make them nops/XFAIL for nommu systems.

You should have removed these two zeroes as well, it's a bit confusing

IMHO you are wrong here. IMHO uCLinux-ng [1], still used libc (used in Buildroot
and openembedded). And log in e5e938f4b7 (2009) suggests that it's about libc.
But the question is whether it's still needed. I could try to remove these and
test, but as a separate effort.
We have few of them:
$ git grep -l __UCLIBC__
include/old/tlibio.h
lib/tlibio.c
testcases/kernel/syscalls/fmtmsg/fmtmsg01.c
utils/benchmark/ebizzy-0.3/ebizzy.h
Kind regards,
Petr

Thanks for catching -V. I wonder myself why I removed it.
So far 2 changes, fixes are in remove-UCLINUX.rebased.fixes in my LTP fork:
https://github.com/pevik/ltp/commits/remove-UCLINUX.rebased.fixes/
Kind regards,
Petr

You are right, these should be converted into configure checks later on.
And the tlibio should probably be rewritten completely. So let's keep
the patch as it is.

I started to rewrite part of that library when I was working on
growfiles test rewrite, but the complexity of it, the amount of nested
statements and macro directives made me crazy.
Waiting for a better moment to restart rewriting it, but work is on-going.

Maybe it would be better to do this in a steps, first remove everything
that is inside the ifdefs for hpux, sgi etc. and only then start working
with the actual code...

Well that's the easiest part. growfiles has a really huge amount of bad
code, it's the biggest in the whole LTP suite and (unfortunately) it's a
really important one.
It will take a bit...probably it will be incremental.
