17cc27d5b7 nptl: Remove tst-cancel-wrappers test and related macros
With upcoming BZ#12683 fix, syscall cancellation is not more handled
by {libc,pthread,librt}_{enable,disable}_asynccancel symbols.  This renders
both LIBC_CANCEL_HANDLED and empty declaration and tst-cancel-wrappers.sh
unrequired.  This patch removes both the macro and the nptl test.

Checked on x86_64-linux-gnu.

5c112f1b62 Avoid insecure usage of tmpnam in tests.
Various glibc testcases use tmpnam in ways subject to race conditions
(generate a temporary file name, then later open that file without
O_EXCL).

This patch fixes those tests to use mkstemp - generally a minimal
local fix to use mkstemp instead of tmpnam, rather than a larger fix
to use other testsuite infrastructure for temporary files.  The
unchanged use of tmpnam in posix/wordexp-test.c would fail safe in the
event of a race (it's generating a name for use with mkdir rather than
for a file to be opened for writing).

Tested for x86_64.

06ab719d30 Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)
This patch fixes the OFD ("file private") locks for architectures that
support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The
issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and
F_{SET,GET}L{W}K64 expects a flock64 argument and when using old
F_OFD_* flags with a non LFS flock argument the kernel might interpret
the underlying data wrongly.  Kernel idea originally was to avoid using
such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS
semantic as default it is possible to provide the functionality and
avoid the bogus struct kernel passing by adjusting the struct manually
for the required flags.

The idea follows other LFS interfaces that provide two symbols:

  1. A new LFS fcntl64 is added on default ABI with the usual macros to
     select it for FILE_OFFSET_BITS=64.

  2. The Linux non-LFS fcntl use a stack allocated struct flock64 for
     F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided
     struct.

  3. Keep a compat symbol with old broken semantic for architectures
     that do not define __OFF_T_MATCHES_OFF64_T.

So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will
aliased to fcntl and no adjustment would be required.  So to actually
use F_OFD_* with LFS support the source must be built with LFS support
(_FILE_OFFSET_BITS=64).

Also F_OFD_SETLKW command is handled a cancellation point, as for
F_SETLKW{64}.

329ea513b4 Avoid cancellable I/O primitives in ld.so.
Neither the <dlfcn.h> entry points, nor lazy symbol resolution, nor
initial shared library load-up, are cancellation points, so ld.so
should exclusively use I/O primitives that are not cancellable.  We
currently achieve this by having the cancellation hooks compile as
no-ops when IS_IN(rtld); this patch changes to using exclusively
_nocancel primitives in the source code instead, which makes the
intent clearer and significantly reduces the amount of code compiled
under IS_IN(rtld) as well as IS_IN(libc) -- in particular,
elf/Makefile no longer thinks we require a copy of unwind.c in
rtld-libc.a.  (The older mechanism is preserved as a backstop.)

The bulk of the change is splitting up the files that define the
_nocancel I/O functions, so they don't also define the variants that
*are* cancellation points; after which, the existing logic for picking
out the bits of libc that need to be recompiled as part of ld.so Just
Works.  I did this for all of the _nocancel functions, not just the
ones used by ld.so, for consistency.

fcntl was a little tricky because it's only a cancellation point for
certain opcodes (F_SETLKW(64), which can block), and the existing
__fcntl_nocancel wasn't applying the FCNTL_ADJUST_CMD hook, which
strikes me as asking for trouble, especially as the only nontrivial
definition of FCNTL_ADJUST_CMD (for powerpc64) changes F_*LK* opcodes.
To fix this, fcntl_common moves to fcntl_nocancel.c along with
__fcntl_nocancel, and changes its name to the extern (but hidden)
symbol __fcntl_nocancel_adjusted, so that regular fcntl can continue
calling it.  __fcntl_nocancel now applies FCNTL_ADJUST_CMD; so that
both both fcntl.c and fcntl_nocancel.c can see it, the only nontrivial
definition moves from sysdeps/u/s/l/powerpc/powerpc64/fcntl.c to
.../powerpc64/sysdep.h and becomes entirely a macro, instead of a macro
that calls an inline function.

The nptl version of libpthread also changes a little, because its
"compat-routines" formerly included files that defined all the
_nocancel functions it uses; instead of continuing to duplicate them,
I exported the relevant ones from libc.so as GLIBC_PRIVATE.  Since the
Linux fcntl.c calls a function defined by fcntl_nocancel.c, it can no
longer be used from libpthread.so; instead, introduce a custom
forwarder, pt-fcntl.c, and export __libc_fcntl from libc.so as
GLIBC_PRIVATE.  The nios2-linux ABI doesn't include a copy of vfork()
in libpthread, and it was handling that by manipulating
libpthread-routines in .../linux/nios2/Makefile; it is cleaner to do
what other such ports do, and have a pt-vfork.S that defines no symbols.

Right now, it appears that Hurd does not implement _nocancel I/O, so
sysdeps/generic/not-cancel.h will forward everything back to the
regular functions.  This changed the names of some of the functions
that sysdeps/mach/hurd/dl-sysdep.c needs to interpose.

52a713fdd0 linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679]
Currently getcwd(3) can succeed without returning an absolute path
because the underlying getcwd syscall, starting with linux commit
v2.6.36-rc1~96^2~2, may succeed without returning an absolute path.

This is a conformance issue because "The getcwd() function shall
place an absolute pathname of the current working directory
in the array pointed to by buf, and return buf".

This is also a security issue because a non-absolute path returned
by getcwd(3) causes a buffer underflow in realpath(3).

Fix this by checking the path returned by getcwd syscall and falling
back to generic_getcwd if the path is not absolute, effectively making
getcwd(3) fail with ENOENT.  The error code is chosen for consistency
with the case when the current directory is unlinked.

95511aab9d Fix testing with read-only source directory.
Three tests fail with a read-only source directory because they try to
write into the source directory.  None of these write into it in a way
that should actually be problematic for concurrent builds sharing the
same writable source directory, but avoiding any writing into the
source directory (from testing, or from building glibc if the source
timestamps are properly ordered) is still a good idea, as being able
to build with read-only sources helps make sure there isn't anything
that could cause problems for concurrent builds.

This patch changes the tests in question to use either /tmp or the
build directory to write their temporary files (or to test O_TMPFILE,
as applicable).

Tested for x86_64.

	* io/Makefile (tst-open-tmpfile-ARGS): New variable.
	* posix/tst-mmap-offset.c (fname): Use /tmp.
	* stdlib/tst-setcontext3.sh (tempfile): Use ${objpfx}.

a992f506ff Remove __need macros from signal.h.
The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h.  The others
get bits/types/ headers.

Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion.  Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API).  Relatedly, the public signal.h no longer
declares any of those functions.  The obsolete sigmask() macro no
longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.

New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary.  Ports to other operating systems
are strongly encouraged to generalize this scheme further.

d76d370355 Fix missing timespec definition for sys/stat.h (BZ #21371)
As indicated by the bug report, the 'struct timespec' definition
is not defined for '_XOPEN_SOURCE=700' and '_POSIX_C_SOURCE=200112L'.

It is because current code only includes its definition if __USE_ATFILE
is defined and the define is only set with:

  1. _GNU_SOURCE and/or _ATFILE_SOURCE definition.
  2. _POSIX_C_SOURCE >= 200809L

However, the 'st_*' fields in 'struct stat' are defined if __USE_XOPEN2K8.
This patch uses the same logic for 'struct timespec' inclusion.

Tested on x86_64-linux-gnu.

	* io/sys/stat.h: Use __USE_XOPEN2K8 insteaf of __USE_ATFILE for
	struct timespec definition.

9090848d06 Narrowing the visibility of libc-internal.h even further.
posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar
to what was done with libc-diag.h, I have split the definitions of
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN
to a new header, libc-pointer-arith.h.

It then occurred to me that the remaining declarations in libc-internal.h
are mostly to do with early initialization, and probably most of the
files including it, even in the core code, don't need it anymore.  Indeed,
only 19 files actually need what remains of libc-internal.h.  23 others
need libc-diag.h instead, and 12 need libc-pointer-arith.h instead.
No file needs more than one of them, and 16 don't need any of them!

So, with this patch, libc-internal.h stops including libc-diag.h as
well as losing the pointer arithmetic macros, and all including files
are adjusted.

        * include/libc-pointer-arith.h: New file.  Define
	cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and

	moved from here.  Don't include libc-diag.h anymore either.

df19fdcfec Fix MIPS n32 lseek, lseek64 (bug 21019).
The lseek consolidation broke lseek64 for MIPS n32, so resulting in
io/test-lfs failing with an incorrect return from ftello64.  This
configuration uses the lseek syscall with a 64-bit return value; as
the C syscall macros return long, they cannot be used in this case and
so an assembly implementation is needed; accordingly, this patch adds
lseek64 back to syscalls.list for this configuration.

lseek was also broken, truncating the result without checking for
overflow.  lseek however was already broken before the consolidation;
it aliased lseek64 so would return an out-of-range value, resulting in
architecturally undefined behavior in the caller if it tried to use a
non-sign-extended value with a 32-bit instruction.  This patch adds a
custom lseek implementation in C for n32, which calls __lseek64 to get
the 64-bit value then checks for overflow.

Because the prior lseek breakage did not show in test results, and the
lseek64 breakage showed only indirectly through tests of ftello64,
test coverage was clearly inadequate.  This patch extends
io/test-lfs.c to test the lseek64 return value (at a point where it
has already seeked over 2GB into a file), and then to test the lseek
return value (with the latter's expectations depending on whether
off_t is smaller than off64_t).

Tested for mips64 n32.  Also tested test-lfs for x86_64 and x86, where
as expected it passes.

	[BZ #21019]
	* sysdeps/unix/sysv/linux/mips/mips64/n32/syscalls.list (lseek64):
	New syscall entry.
	* sysdeps/unix/sysv/linux/mips/mips64/n32/lseek.c: New file.
	* io/test-lfs.c (do_test): Test offset returned from lseek64 and
	lseek.

c23de0aacb support: Introduce new subdirectory for test infrastructure
The new test driver in <support/test-driver.c> has feature parity with
the old one.  The main difference is that its hooking mechanism is
based on functions and function pointers instead of macros.  This
commit also implements a new environment variable, TEST_COREDUMPS,
which disables the code which disables coredumps (that is, it enables
them if the invocation environment has not disabled them).

<test-skeleton.c> defines wrapper functions so that it is possible to
use existing macros with the new-style hook functionality.

This commit changes only a few test cases to the new test driver, to
make sure that it works as expected.

afcf3cd8eb New internal function __access_noerrno
Implement an internal version of __access called __access_noerrno that
avoids setting errno.  This is useful to check accessibility of files
very early on in process startup i.e. before TLS setup.  This allows
tunables to replace MALLOC_CHECK_ safely (i.e. check existence of
/etc/suid-debug to enable/disable MALLOC_CHECK) and at the same time
initialize very early so that it can override IFUNCs.

Checked on x86_64.

	* hurd/hurd.h (__hurd_fail_noerrno): New function.
	* include/unistd.h [IS_IN (rtld) || !defined SHARED]: Declare
	__access_noerrno.

45ff2bfcb3 Consolidate posix_fallocate{64} implementations
This patch consolidates all the posix_fallocate{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/posix_fallocate{64}.c).  It also removes
the syscall from the auto-generation using assembly macros.

The macro SYSCALL_LL{64} is used to handle the offset argument along with
the new INTERNAL_SYSCALL_CALL macro to define correct argument count for
internal INTERNAL_SYSCALL call.

Tested on x86_64, i686, x32, aarch64, ppc64le, and armhf.

05b68e14b1 Installed-header hygiene (BZ#20366): time.h types.
Many headers are expected to expose a subset of the type definitions
in time.h.  time.h has a whole bunch of messy logic for conditionally
defining some its types and structs, but, as best I can tell, this
has never worked 100%.  In particular, __need_timespec is ineffective
if _TIME_H has already been defined, which means that if you compile

  #include <time.h>
  #include <sched.h>

with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get

In file included from test.c:2:0:
/usr/include/sched.h:74:57: warning: "struct timespec" declared inside
  parameter list will not be visible outside of this definition or declaration
 extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW;
                                                         ^~~~~~~~

And if you want to _use_ sched_rr_get_interval in a TU compiled that
way, you're hosed.

This patch replaces all of that with small bits/types/TYPE.h headers
as introduced earlier.  time.h and bits/time.h are now *much* simpler,
and a lot of other headers are slightly simpler.

11160cb76f Installed-header hygiene (BZ#20366): obsolete BSD u_* types.
The types u_char, u_short, u_int, u_long, ushort, uint, ulong, u_int8_t,
u_int16_t, u_int32_t, u_int64_t, quad_t, and u_quad_t are BSDisms that
have never been standardized.  While glibc should continue to *provide*
these types for compatibility's sake, its public headers should not
use them.

The meat of this change was mechanically generated by the following
shell command:

    perl -pi~ -e '
        s/\b(__)?u_char\b/unsigned char/g;
        s/\b(__)?u_?short\b/unsigned short/g;
        s/\b(__)?u_?int\b/unsigned int/g;
        s/\b(__)?u_?long\b/unsigned long/g;
        s/\b(__)?u_int8_t\b/uint8_t/g;
        s/\b(__)?u_int16_t\b/uint16_t/g;
        s/\b(__)?u_int32_t\b/uint32_t/g;
        s/\b(__)?u_int64_t\b/uint64_t/g;
        s/\b(__)?u_quad_t\b/uint64_t/g;
        s/\b(__)?quad_t\b/uint64_t/g;
    ' $(grep -lE -e '\<((__)?(quad_t|u(short|int|long|_(char|short|int([0-9]+_t)?|long|quad_t))))\>' \
        $(grep -LE '\<(_(SYS|BITS)_TYPES_H|rpc/(rpc|rpc_msg|types|xdr)\.h)\>' \
          $(find . \( -false $(sed 's/^/-o -name /' all-installed-headers) \
                   \) -printf '%P\n' | sort -u)))

where 'all-installed-headers' was a list of the basenames of all installed
header files, manually extracted from the Makefiles.  Non-installed
wrapper headers in include/ are also adjusted, for consistency.
I then manually fixed up indentation and line-wrapping.

sys/types.h and bits/types.h are excluded because they must continue
to define the u_* types (under __USE_MISC) for compatibility with
applications.  They do not use these types themselves.

All headers that (transitively) include rpc/types.h are also excluded,
for three reasons.  First, the u_* types are defined by rpc/types.h,
unconditionally (not just under __USE_MISC) so they are logically part
of the SunRPC API.  Second, many of those headers appear to be
machine-generated.  Third, it's my understanding that we are getting
rid of as much of SunRPC as possible in the near future.

(The one file under sunrpc/ that's touched, sunrpc/rpc/rpc_des.h, does
*not* include rpc/types.h.  This may itself be a bug.)

After changing from u_intNN_t to uintNN_t, a number of headers now
need to include stdint.h to pick up those types.  It might be more
hygenic, namespace-wise, to use __uintNN_t instead, but none of these
headers are bound by ISO or POSIX to do so, and it's unlikely that
anyone using them will be bothered.  (The two files that were using
__-prefixed versions of the u_types, sysdeps/mach/hurd/net/route.h and
sysdeps/unix/sysv/linux/net/route.h, both already also contained uses of
the unprefixed versions.)

Some of these files directly included features.h and/or sys/cdefs.h,
which I removed, as the style generally seems to be to let sys/types.h
do that for us.  (This does not change the set of definitions exposed
by any header; sys/types.h unconditionally includes both features.h
and sys/cdefs.h.)

One file included asm/types.h unnecessarily.

67b73ea479 tst-open-tmpfile: Add checks for open64, openat64, linkat
The /proc/self/fd approach is expected to work for all users
(with and without CAP_DAC_READ_SEARCH).

85f7554cd9 Add test case for O_TMPFILE handling in open, openat
Also put xasprintf into test-skeleton.c (written in such a way that
including <stdarg.h> is not needed).

9ff81856db Make sys/stat.h define S_IFSOCK, S_ISSOCK for XPG4 (bug 20076).
sys/stat.h should define S_IFSOCK and S_ISSOCK for XPG4 (XNS), but
does not.  This patch corrects the relevant header conditionals.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	[BZ #20076]
	* io/sys/stat.h (S_IFSOCK): Define for [__USE_XOPEN_EXTENDED]
	instead of [__USE_UNIX98].
	(S_ISSOCK): Likewise.
	* conform/Makefile (test-xfail-XPG4/sys/stat.h/conform): Remove
	variable.

8da7d8f877 Fix sys/stat.h fchmod namespace (bug 20073).
sys/stat.h declares fchmod if __USE_POSIX (i.e. POSIX.1:1990).  But it
was actually added in 1993 and also in XPG4.  This patch changes the
conditions to the correct __USE_POSIX199309 || __USE_XOPEN_EXTENDED.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	[BZ #20073]
	* io/sys/stat.h (fchmod): Declare for
	[__USE_POSIX199309 || __USE_XOPEN_EXTENDED], not [__USE_POSIX].
	* conform/Makefile (test-xfail-XPG3/sys/stat.h/conform): Remove
	variable.
