Handle multiple versions of jemalloc

Improve the man for strtoi() (and consequently strtou())

PR lib/58461 PR lib/58453

Improve the wording so it is clearer exactly what strtoi() is
intended to do in various cases.

While here, add, in the most minimalist way possible, the
strtoi_l(), and so also strtou_l(), functions, which seem to
have been previously undocumented.

Do some linguistic gymnastics so that the conversion of the
page from strtoi(3) -> strtou(3) will not generate "an unitmax_t"
which is incorrect, we need "a unitmax_t" - one of those was
easy to fix in the Makefile sed script, the others would have
been more difficult, so reword instead.

- new test for strtoi

- separate manpages for strto{i,u} from the ones for strto{u,}l
From: Kamil Rytarowski

Introduce reallocarr(3) for easy (re)allocation of memory with overflow
checks. Compared to OpenBSD's reallocarray, makes it easier to avoid memory
leaks on allocation failures and it doesn't depend on malloc(0) != NULL
for correct error checking. Compared to plain realloc, it also avoids
the problem of intermediate integer overflows. The trade-off is the use
of void * to side step C type system with regard to generic pointer to
pointer.

Revert addition to reallocarray to the malloc man page, but keep
the examples. Add separate manual page to reallocarray explaining
what are the problems with it.

Add and use reallocarray() to prevent a multiplication overflow in allocation.
Reported by Guido Vranken, thanks!

Collect also the division functions to single place, div(3).

Collect abs(3), labs(3), llabs(3), and imaxabs(3) to a single small page.

Improve and simplify implementation of *env(3) functions:
- Use RB tree to keep track of memory allocated via setenv(3) as
suggested by Enami Tsugutomo in private e-mail.
This simplifies the code a lot as we no longer need to keep the size
of "environ" in sync with an array of allocated environment variables.
It also makes it possible to free environment variables in unsetenv(3)
if something has changed the order of the "environ" array.
- Fix a bug in getenv(3) and getenv_r(3) which would return bogus
results e.g. for " getenv("A=B") " if an environment variable "A"
with value "B=C" exists.
- Clean up the internal functions:
- Don't expose the read/write lock for the environment to other parts
of "libc". Provide locking functions instead.
- Use "bool" to report success or failure.
- Use "ssize_t" or "size_t" instead of "int" for indexes.
- Provide internal functions with simpler interfaces e.g. don't
combine return values and reference arguments.
- Don't copy "environ" into an allocated block unless we really need
to grow it.

Code reviewed by Joerg Sonnenberger and Christos Zoulas, tested by
Joerg Sonnenberger and me. These changes also fix problems in
zsh 4.3.* and pam_ssh according to Joerg.

Split the implementation details of malloc(3) to a separate jemalloc(3)

Provide symbol definitions for environ and __progname. These are duplicate
definitions to the ones provided by csu, but harmless since the linker resolves
them. There are 3 non weak data symbols provided in crt0.o:

D __progname [initialized data, assigned to ""]
B __ps_strings [BSS since assigned to 0]
C environ [common, uninitialized]

__ps_strings had already a second definition in libc (in BSS), now we added
__progname and __ps_strings (in BSS).

To get rid of the duplicate definition, we can remove them from csu, and
move the assignments to libc.

This is done so that libc has no undefined symbols so that linker maps

Implement mark & sweep garbage collection as suggested by Enami Tsugutomo

1.) We previously allocated memory for the environment array which

2.) We find a non-NULL pointer in the allocated environment array after
the end of the environment. This happens if the applications attempts
to clear the environment with something like "environ[0] = NULL;".

Fix typos in comment.

1.) Rename internal function __findvar() to __findenvvar().
2.) Add a wrapper function __findenv() which implements the previous
*internal* interface. It turns out that ld.elf_so(1) and pthread(3)
both use it.

Stripping e.g. "LD_LIBRARY_PATH" from the environment while running

Change the previous cast from unsigned int to unsigned long

This code produces the same result and is consistent with the previous
lines. Only the least significant 16 bites (unsigned short) are meaningful.

Avoid undefined behavior in the rand48(3) implementation

Instead of implicid promotion to signed int,
explicitly cast the arguments to unsigned int.

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

atexit(3): Sprinkle comments about __cxa_atexit assertion.

Also archive dead codesourcery.com link.

No functional change intended -- comments only.

revert now that tsan has been made to call atexit() when dso == NULL.
lsan and asan will need to be fixed too.

Disable the dso assertion for now because the thread sanitizer calls:
tsan_interceptors_posix.cpp: if (REAL(__cxa_atexit)(&finalize, 0, 0))

Assert that __cxa_atexit is not used with NULL as DSO. Don't use
__cxa_atexit directly from atexit, they have different behavior.

Revert previous on demand.

Rationale:

The DSO handle is a required part of the (external) __cxa_atexit interface.
The atexit mapping is an implementation detail and not part of the public
interface. Doing it directly creates UB as it involves casting function
pointers between incompatible types.

-- Joerg

Correct handling of __cxa_atexit(a,b,NULL) in libc

In the NetBSD implementation and suggested by Itanium C++ ABI, we wrap
the atexit(x) call as __cxa_atexit(x,NULL,NULL).

__cxa_atexit() is an internal function for the usage of C++.

Correct a bug that __cxa_atexit(x,y,NULL) is handled in the same way as
atexit(x) (which is simplified to __cxa_atexit(x,NULL,NULL).

This misbehavior has been detected in the Thread Sanitizer port to NetBSD.

Keep track of atexit functions that are added while processing

Ensure that the struct atexit_handler has been removed from the list
of pending atexit handlers before the structure is reused. This prevents
__cxa_finalize from going into an infinite loop when an atexit handler
register a new atexit handler as in:

#include <stdlib.h>

void two(void) {
}

void one(void) {
atexit(two);

When implementing a recursive mutex, it helps if you remember to

Fixes the problem of uic dying with a no-next-thread assertion while
building kdeadmin3; reported by Perry Metzger and others on
tech-pkg.

Fix lib/20558:
A dynamically linked program invokes the rtld cleanup routine via
an atexit handler. This rtld cleanup routine invokes _fini() for
shared libraries, which in-turn invoke __cxa_finalize() with their
DSO handle. By luck, this happens to work okay for non-threaded
programs, but for a threaded program, this leads to deadlock (sometimes
manifested as an assertion failure, if the program didn't actually
create any threads).

Fixed by teaching __cxa_finalize() that it can be recursively invoked,
adjusting the handler list manipulation accordingly.

Rewrite atexit(3), and add support for __cxa_atexit()/__cxa_finalize(),
as specified by the C++ ABI for Itanium. Despite the ABI document's name,
many of the items in it are implemented for other architectures.

Revert namespacing of atoi(3)

Sanitizers can handle recursive interceptions in some / most cases, if they

changes - I will be back to it.

Keep namespace of asctime() as this can be a cancellation point according
to POSIX. Right now it's not implemented on NetBSD. Defer it for later.

Keep weak symbols and namespace for wait6(2) as this could be a
cancellation point as well. Defer this for later.

Sanitizers's [recursive] interceptors are a hack and moving one way or
another can cause new sets of problems. Recursive ones can be useful and
cause problems (on Linux there are known with with signal handlers).

sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

New-style RCS ids.

Removed trailing comma from SEE ALSO section.

Add RCS indentifiers.

branches: 1.1.1;
Initial revision

Sync phk malloc.c with the latest one from FreeBSD. This gives us the
same api as jemalloc by:

- adding posix_memalign()
- moving calloc in the same file
- renaming malloc_options -> _malloc_options

branches: 1.13.22;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

restore the previous form of the condition checking malloc() return value, which
was changed in previous revision

allow calloc(0, x) and calloc(x, 0). sync w/openbsd

New-style RCS ids.

Changed to use memset() instead of bzero().

Split cfree() out of calloc.c.
If a user compiling in a strict ANSI or strict POSIX environment uses his
own function named cfree (which is legal, since cfree is not in a restricted
namespace) and calloc, the link will fail due to the cfree in calloc.c.

Declare rcsid strings so they are stored in text segment.

branches: 1.1.4;
Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.

If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.

Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

fix various typos in comment, documentation and log messages.

Add missing __RCSID()

Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

RCS Id Police.

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

branches: 1.2.8;
Rename intenral _rand_foo variables to __rand_foo, as _rand_foo is in the
user's namespace.

<math.h> is just needed for the ldexp() call in erand48() -

Add missing __RCSID()

Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

switch byteorder of seed to match previous (and documented) behaviour

Rewrite erand48() to put the random bits into the mantissa by simple
bitshifts instead of calling ldexp() three times.
(for ieee doubles only -- vax can't use it, so the old version
needs to stay around)
This removes the dependency on ldexp() which also didn't participate in
the usual __RENAME game, thus lead to confusion.
In addition, this version is almost 3 times as fast for me.

Remove __P()

Pass down ELF Auxillary Vectors for static NetBSD binaries too.
Rename __libc_init to _libc_init and call it explicitly from CSU code.
This enforces the constructor run order for newly linked programs.
Keep it as constructor with run-once semantic for binary compatibility.
Implement dl_iterate_phdr for statically linked programs.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

Only do the __libc_init hack in libc, i.e. remove it from ld.elf_so.

This fixes hppa ld.elf_so by reducing the number of PLABELs required to
the number before the hack was applied.

Hi Joerg!

Ensure that initfini.c is referenced by exit.c. The start up code has to
reference the latter as a return of main() results in a call to exit(3),
so this ensures that the libc constructors are run for statically linked
programs. Fixes PR 37454.

branches: 1.11.12; 1.11.20;
Build a local copy of exit that doesn't call __cxa_finalize. It's not
needed and drags in a lot of libc via free.

Rewrite atexit(3), and add support for __cxa_atexit()/__cxa_finalize(),
as specified by the C++ ABI for Itanium. Despite the ABI document's name,
many of the items in it are implemented for other architectures.
