Description

2014-07-21 11:43:25 UTC
John Haxby reported this as a functionality bug in 2005: “The first problem is that it looks as though the ".so" is appended to the shared library name after the terminating NUL” <https://www.sourceware.org/ml/libc-alpha/2005-12/msg00091.html> This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".
The branch, master has been updated
via a1a6a401ab0a3c9f15fb7eaebbdcee24192254e8 (commit)
from e4e7cfd287686d26fce2218ed5b2d383db5e338a (commit)
Those revisions listed above that are new to this repository have

Use NSS_STATUS_TRYAGAIN to indicate insufficient buffer (BZ #16878)
The netgroups nss modules in the glibc tree use NSS_STATUS_UNAVAIL
(with errno as ERANGE) when the supplied buffer does not have
sufficient space for the result. This is wrong, because the canonical
way to indicate insufficient buffer is to set the errno to ERANGE and
the status to NSS_STATUS_TRYAGAIN, as is used by all other modules.
This fixes nscd behaviour when the nss_ldap module returns
NSS_STATUS_TRYAGAIN to indicate that a netgroup entry is too long to
fit into the supplied buffer.

Provide correct buffer length to netgroup queries in nscd (BZ #16695)
The buffer to query netgroup entries is allocated sufficient space for
the netgroup entries and the key to be appended at the end, but it
sends in an incorrect available length to the NSS netgroup query
functions, resulting in overflow of the buffer in some special cases.
The fix here is to factor in the key length when sending the available
buffer and buffer length to the query functions.

The GNU C Library
=================
The GNU C Library version 2.20 is now available.
The GNU C Library is used as *the* C library in the GNU systems
and is widely used on systems with the Linux kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.20 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html

16966, 16967, 16977, 16978, 16984, 16990, 16996, 17009, 17022, 17031,
17042, 17048, 17050, 17058, 17061, 17062, 17069, 17075, 17078, 17079,
17084, 17086, 17088, 17092, 17097, 17125, 17135, 17137, 17150, 17153,
17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354.
* Reverted change of ABI data structures for s390 and s390x:
On s390 and s390x the size of struct ucontext and jmp_buf was increased in
2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
are preserved pointing straight to the same implementation as the old ones.
Given that, new callers will simply provide a too-big buffer to these
functions. Any applications/libraries out there that embed jmp_buf or
ucontext_t in an ABI-relevant data structure that have already been rebuilt
against 2.19 headers will have to rebuilt again. This is necessary in any
case to revert the breakage in their ABI caused by the glibc change.
* Support for file description locks is added to systems running the
Linux kernel. The standard file locking interfaces are extended to
operate on file descriptions, not file descriptors, via the use of
F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
are associated with an open file instead of a process.
* Optimized strchr implementation for AArch64. Contributed by ARM Ltd.
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 2.6.32.
* Running the testsuite no longer terminates as soon as a test fails.
Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
with PASS or FAIL lines for individual tests. A summary of the results is
printed, including a list of failing lists, and "make check" exits with
error status if there were any unexpected failures. "make check
stop-on-test-failure=y" may be used to keep the old behavior.
* The am33 port, which had not worked for several years, has been removed
from ports.
* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
supported; they now act the same as _DEFAULT_SOURCE (but generate a
warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
conflicted with POSIX (support for which was removed in 2.19), the
interfaces those macros enabled remain available when compiling with
_GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
test macros defined.
* Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd.
* Added support for TX lock elision of pthread mutexes on s390 and s390x.
This may improve lock scaling of existing programs on TX capable systems.
The lock elision code is only built with --enable-lock-elision=yes and
then requires a GCC version supporting the TX builtins. With lock elision
default mutexes are elided via __builtin_tbegin, if the cpu supports
transactions. By default lock elision is not enabled and the elision code
is not built.
* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
copy the path argument. This allowed programs to cause posix_spawn to
deference a dangling pointer, or use an unexpected pathname argument if
the string was modified after the posix_spawn_file_actions_addopen
invocation.
* All supported architectures now use the main glibc sysdeps directory
instead of some being in a separate "ports" directory (which was
distributed separately before glibc 2.17).
* The NPTL implementation of POSIX pthreads is no longer an "add-on".
On configurations that support it (all Linux configurations), it's now
used regardless of the --enable-add-ons switch to configure. It is no
longer possible to build such configurations without pthreads support.
* Locale names, including those obtained from environment variables (LANG
and the LC_* variables), are more tightly checked for proper syntax.
setlocale will now fail (with EINVAL) for locale names that are overly
long, contain slashes without starting with a slash, or contain ".." path
components. (CVE-2014-0475) Previously, some valid locale names were
silently replaced with the "C" locale when running in AT_SECURE mode
(e.g., in a SUID program). This is no longer necessary because of the
additional checks.
* On x86-64, the dynamic linker's lazy-binding support is now compatible
with application code using Intel MPX instructions. (With all previous
versions, the MPX register state could be clobbered when making calls
into or out of a shared library.) Note that while the new dynamic
linker is compatible with all known x86 hardware whether or not it
supports Intel MPX, some x86 instruction-set emulators might fail to
handle the new instruction encodings. This is known to affect Valgrind
versions up through 3.9 (but will be fixed in the forthcoming 3.10
release), and might affect other tools that do instruction emulation.
* Support for loadable gconv transliteration modules has been removed.
The support for transliteration modules has been non-functional for
over a decade, and the removal is prompted by security defects. The
normal gconv conversion modules are still supported. Transliteration
with //TRANSLIT is still possible, and the //IGNORE specifier
continues to be supported. (CVE-2014-5119)
* Decoding a crafted input sequence in the character sets IBM933, IBM935,
IBM937, IBM939, IBM1364 could result in an out-of-bounds array read,
resulting a denial-of-service security vulnerability in applications which
use functions related to iconv. (CVE-2014-6040)

PowerPC: Fix gettimeofday ifunc selection
The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where
__vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal
version used within GLIBC) to use the system call version instead of the vDSO one.
This patch changes the check if vDSO is available to get its value directly
instead of rely on __vdso_gettimeofday.
This patch changes it by getting the vDSO value directly.
It fixes BZ#16431.

PowerPC: Fix ftime gettimeofday internal call returning bogus data
This patches fixes BZ#16430 by setting a different symbol for internal
GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol
is defined as hidden (which is the case for gettimeofday and time) the
compiler will create local branches (symbol@local) and linker will not
create PLT calls (required for IFUNC). This will leads to internal symbol
calling the IFUNC resolver instead of the resolved symbol.
For PPC64 this behavior does not occur because a call to a function in
another translation unit might use a different toc pointer thus requiring
a PLT call.

PowerPC: Fix vDSO missing ODP entries
This patch fixes the vDSO symbol used directed in IFUNC resolver where
they do not have an associated ODP entry leading to undefined behavior
in some cases. It adds an artificial OPD static entry to such cases
and set its TOC to non 0 to avoid triggering lazy resolutions.

CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of "$((... ``))"
where "..." can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass
the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
in exec_comm(), the only place that can execute a shell. All other
checks for WRDE_NOCMD are superfluous and removed.
We expand the testsuite and add 3 new regression tests of roughly
the same form but with a couple of nested levels.
On top of the 3 new tests we add fork validation to the WRDE_NOCMD
testing. If any forks are detected during the execution of a wordexp()
call with WRDE_NOCMD, the test is marked as failed. This is slightly
heuristic since vfork might be used in the future, but it provides a
higher level of assurance that no shells were executed as part of
command substitution with WRDE_NOCMD in effect. In addition it doesn't
require libpthread or libdl, instead we use the public implementation
namespace function __register_atfork (already part of the public ABI
for libpthread).
Tested on x86_64 with no regressions.

malloc: Check for integer overflow in pvalloc.
A large bytes parameter to pvalloc could cause an integer overflow
and corrupt allocator internals. Check the overflow does not occur
before continuing with the allocation.

BZ #15754: CVE-2013-4788
The pointer guard used for pointer mangling was not initialized for
static applications resulting in the security feature being disabled.
The pointer guard is now correctly initialized to a random value for
static applications. Existing static applications need to be
recompiled to take advantage of the fix.
The test tst-ptrguard1-static and tst-ptrguard1 add regression
coverage to ensure the pointer guards are sufficiently random
and initialized to a default value.

Check for integer overflow in cache size computation in strcoll
strcoll is implemented using a cache for indices and weights of
collation sequences in the strings so that subsequent passes do not
have to search through collation data again. For very large string
inputs, the cache size computation could overflow. In such a case,
use the fallback function that does not cache indices and weights of
collation sequences.
Fixes CVE-2012-4412.

CVE-2013-2207, BZ #15755: Disable pt_chown.
The helper binary pt_chown tricked into granting access to another
user's pseudo-terminal.
Pre-conditions for the attack:
* Attacker with local user account
* Kernel with FUSE support
* "user_allow_other" in /etc/fuse.conf
* Victim with allocated slave in /dev/pts
Using the setuid installed pt_chown and a weak check on whether a file
descriptor is a tty, an attacker could fake a pty check using FUSE and
trick pt_chown to grant ownership of a pty descriptor that the current
user does not own. It cannot access /dev/pts/ptmx however.
In most modern distributions pt_chown is not needed because devpts
is enabled by default. The fix for this CVE is to disable building
and using pt_chown by default. We still provide a configure option
to enable hte use of pt_chown but distributions do so at their own
risk.

CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of "$((... ``))"
where "..." can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass
the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
in exec_comm(), the only place that can execute a shell. All other
checks for WRDE_NOCMD are superfluous and removed.
We expand the testsuite and add 3 new regression tests of roughly
the same form but with a couple of nested levels.
On top of the 3 new tests we add fork validation to the WRDE_NOCMD
testing. If any forks are detected during the execution of a wordexp()
call with WRDE_NOCMD, the test is marked as failed. This is slightly
heuristic since vfork might be used in the future, but it provides a
higher level of assurance that no shells were executed as part of
command substitution with WRDE_NOCMD in effect. In addition it doesn't
require libpthread or libdl, instead we use the public implementation
namespace function __register_atfork (already part of the public ABI
for libpthread).
Tested on x86_64 with no regressions.

is no need to specialized powerpc memmove implementation. This patch
moves the define set to powerpc memcopy and cleanup its definition on
powerpc code.

PowerPC: optimized memmove for POWER7/PPC64
This patch adds an optimized memmove optimization for POWER7/powerpc64.
Basically the idea is to use the memcpy for POWER7 on non-overlapped
memory regions and a optimized backward memcpy for memory regions
that overlap (similar to the idea of string/memmove.c).
The backward memcpy algorithm used is similar the one use for memcpy for
POWER7, with adjustments done for alignment. The difference is memory
is always aligned to 16 bytes before using VSX/altivec instructions.

PowerPC: memmove default implementation cleanup
This patch removes the powerpc specific logic in memmove and instead
include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined.
This lead in a increase performance, since the constraints to use
memcpy in powerpc code are too restrictive and memcpy can be used for
any forward memmove.

PowerPC: Fix bzero definition for static libc for PPC32
This patch fixes an issue for powerpc32-fpu static build which fails
with an 'bzero' undefined reference. This patch adds bzero ifunc selector
for static builds and fixes the '__bzero_ppc' reference to default
memset symbol (since static memset build does not provide ifunc
selector).
Fixes BZ#16689.

PowerPC: Fix gettimeofday ifunc selection
The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where
__vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal
version used within GLIBC) to use the system call version instead of the vDSO one.
This patch changes the check if vDSO is available to get its value directly
instead of rely on __vdso_gettimeofday.
This patch changes it by getting the vDSO value directly.
It fixes BZ#16431.

PowerPC: Fix ftime gettimeofday internal call returning bogus data
This patches fixes BZ#16430 by setting a different symbol for internal
GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol
is defined as hidden (which is the case for gettimeofday and time) the
compiler will create local branches (symbol@local) and linker will not
create PLT calls (required for IFUNC). This will leads to internal symbol
calling the IFUNC resolver instead of the resolved symbol.
For PPC64 this behavior does not occur because a call to a function in
another translation unit might use a different toc pointer thus requiring
a PLT call.

CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of "$((... ``))"
where "..." can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass
the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
in exec_comm(), the only place that can execute a shell. All other
checks for WRDE_NOCMD are superfluous and removed.
We expand the testsuite and add 3 new regression tests of roughly
the same form but with a couple of nested levels.
On top of the 3 new tests we add fork validation to the WRDE_NOCMD
testing. If any forks are detected during the execution of a wordexp()
call with WRDE_NOCMD, the test is marked as failed. This is slightly
heuristic since vfork might be used in the future, but it provides a
higher level of assurance that no shells were executed as part of
command substitution with WRDE_NOCMD in effect. In addition it doesn't
require libpthread or libdl, instead we use the public implementation
namespace function __register_atfork (already part of the public ABI
for libpthread).
Tested on x86_64 with no regressions.

BZ #15754: CVE-2013-4788
The pointer guard used for pointer mangling was not initialized for
static applications resulting in the security feature being disabled.
The pointer guard is now correctly initialized to a random value for
static applications. Existing static applications need to be
recompiled to take advantage of the fix.
The test tst-ptrguard1-static and tst-ptrguard1 add regression
coverage to ensure the pointer guards are sufficiently random
and initialized to a default value.

Check for integer overflow in cache size computation in strcoll
strcoll is implemented using a cache for indices and weights of
collation sequences in the strings so that subsequent passes do not
have to search through collation data again. For very large string
inputs, the cache size computation could overflow. In such a case,
use the fallback function that does not cache indices and weights of
collation sequences.
Fixes CVE-2012-4412.

CVE-2013-2207, BZ #15755: Disable pt_chown.
The helper binary pt_chown tricked into granting access to another
user's pseudo-terminal.
Pre-conditions for the attack:
* Attacker with local user account
* Kernel with FUSE support
* "user_allow_other" in /etc/fuse.conf
* Victim with allocated slave in /dev/pts
Using the setuid installed pt_chown and a weak check on whether a file
descriptor is a tty, an attacker could fake a pty check using FUSE and
trick pt_chown to grant ownership of a pty descriptor that the current
user does not own. It cannot access /dev/pts/ptmx however.
In most modern distributions pt_chown is not needed because devpts
is enabled by default. The fix for this CVE is to disable building
and using pt_chown by default. We still provide a configure option
to enable hte use of pt_chown but distributions do so at their own
risk.

CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of "$((... ``))"
where "..." can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass
the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
in exec_comm(), the only place that can execute a shell. All other
checks for WRDE_NOCMD are superfluous and removed.
We expand the testsuite and add 3 new regression tests of roughly
the same form but with a couple of nested levels.
On top of the 3 new tests we add fork validation to the WRDE_NOCMD
testing. If any forks are detected during the execution of a wordexp()
call with WRDE_NOCMD, the test is marked as failed. This is slightly
heuristic since vfork might be used in the future, but it provides a
higher level of assurance that no shells were executed as part of
command substitution with WRDE_NOCMD in effect. In addition it doesn't
require libpthread or libdl, instead we use the public implementation
namespace function __register_atfork (already part of the public ABI
for libpthread).
Tested on x86_64 with no regressions.

PowerPC: Align power7 memcpy using VSX to quadword
This patch changes power7 memcpy to use VSX instructions only when
memory is aligned to quardword. It is to avoid unaligned kernel traps
on non-cacheable memory (for instance, memory-mapped I/O).

PowerPC: optimized memmove for POWER7/PPC64
This patch adds an optimized memmove optimization for POWER7/powerpc64.
Basically the idea is to use the memcpy for POWER7 on non-overlapped
memory regions and a optimized backward memcpy for memory regions
that overlap (similar to the idea of string/memmove.c).
The backward memcpy algorithm used is similar the one use for memcpy for
POWER7, with adjustments done for alignment. The difference is memory
is always aligned to 16 bytes before using VSX/altivec instructions.

PowerPC: memmove default implementation cleanup
This patch removes the powerpc specific logic in memmove and instead
include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined.
This lead in a increase performance, since the constraints to use
memcpy in powerpc code are too restrictive and memcpy can be used for
any forward memmove.

with an 'bzero' undefined reference. This patch adds bzero ifunc selector
for static builds and fixes the '__bzero_ppc' reference to default
memset symbol (since static memset build does not provide ifunc
selector).
Fixes BZ#16689.

PowerPC: Fix bzero definition for static libc for PPC64
This patch fixes an issue for powerpc64[le] static build where __bzero
is definied in multiple places (memset-ppc64.o and bzero.o). It is now
defined only in bzero.o and memset-ppc64.o only defined __bzero_ppc for
both dynamic and static library.
Fixes BZ#16683.

PowerPC: strspn optimization for PPC64/POWER7
The optimization is achieved by following techniques:
> hashing of needle.
> hashing avoids scanning of duplicate entries in needle across the string.
> initializing the hash table with Vector instructions (VSX) by quadword access.
> unrolling when scanning for character in string across hash table.

Under certain conditions wscanf can allocate too little memory for the
to-be-scanned arguments and overflow the allocated buffer. The
implementation now correctly computes the required buffer size when
using malloc.
A regression test was added to tst-sscanf.

PowerPC: Fix gettimeofday ifunc selection
The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where
__vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal
version used within GLIBC) to use the system call version instead of the vDSO one.
This patch changes the check if vDSO is available to get its value directly
instead of rely on __vdso_gettimeofday.
This patch changes it by getting the vDSO value directly.
It fixes BZ#16431.

PowerPC: Fix ftime gettimeofday internal call returning bogus data
This patches fixes BZ#16430 by setting a different symbol for internal
GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol
is defined as hidden (which is the case for gettimeofday and time) the
compiler will create local branches (symbol@local) and linker will not
create PLT calls (required for IFUNC). This will leads to internal symbol
calling the IFUNC resolver instead of the resolved symbol.
For PPC64 this behavior does not occur because a call to a function in
another translation unit might use a different toc pointer thus requiring
a PLT call.

CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of "$((... ``))"
where "..." can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass
the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
in exec_comm(), the only place that can execute a shell. All other
checks for WRDE_NOCMD are superfluous and removed.
We expand the testsuite and add 3 new regression tests of roughly
the same form but with a couple of nested levels.
On top of the 3 new tests we add fork validation to the WRDE_NOCMD
testing. If any forks are detected during the execution of a wordexp()
call with WRDE_NOCMD, the test is marked as failed. This is slightly
heuristic since vfork might be used in the future, but it provides a
higher level of assurance that no shells were executed as part of
command substitution with WRDE_NOCMD in effect. In addition it doesn't
require libpthread or libdl, instead we use the public implementation
namespace function __register_atfork (already part of the public ABI
for libpthread).
Tested on x86_64 with no regressions.

BZ #15754: CVE-2013-4788
The pointer guard used for pointer mangling was not initialized for
static applications resulting in the security feature being disabled.
The pointer guard is now correctly initialized to a random value for
static applications. Existing static applications need to be
recompiled to take advantage of the fix.
The test tst-ptrguard1-static and tst-ptrguard1 add regression
coverage to ensure the pointer guards are sufficiently random
and initialized to a default value.

Check for integer overflow in cache size computation in strcoll
strcoll is implemented using a cache for indices and weights of
collation sequences in the strings so that subsequent passes do not
have to search through collation data again. For very large string
inputs, the cache size computation could overflow. In such a case,
use the fallback function that does not cache indices and weights of
collation sequences.
Fixes CVE-2012-4412.

Fall back to non-cached sequence traversal and comparison on malloc fail
strcoll currently falls back to alloca if malloc fails, resulting in a
possible stack overflow. This patch implements sequence traversal and
comparison without caching indices and rules.

Fix stack overflow due to large AF_INET6 requests
Resolves #16072 (CVE-2013-4458).
This patch fixes another stack overflow in getaddrinfo when it is
called with AF_INET6. The AF_UNSPEC case was fixed as CVE-2013-1914,
but the AF_INET6 case went undetected back then.

CVE-2013-2207, BZ #15755: Disable pt_chown.
The helper binary pt_chown tricked into granting access to another
user's pseudo-terminal.
Pre-conditions for the attack:
* Attacker with local user account
* Kernel with FUSE support
* "user_allow_other" in /etc/fuse.conf
* Victim with allocated slave in /dev/pts
Using the setuid installed pt_chown and a weak check on whether a file
descriptor is a tty, an attacker could fake a pty check using FUSE and
trick pt_chown to grant ownership of a pty descriptor that the current
user does not own. It cannot access /dev/pts/ptmx however.
In most modern distributions pt_chown is not needed because devpts
is enabled by default. The fix for this CVE is to disable building
and using pt_chown by default. We still provide a configure option
to enable hte use of pt_chown but distributions do so at their own
risk.
