nptl: Fix sem_wait and sem_timedwait cancellation (BZ#18243)
This patch fixes both sem_wait and sem_timedwait cancellation point for
uncontended case. In this scenario only atomics are involved and thus
the futex cancellable call is not issue and a pending cancellation signal
is not handled.
The fix is straighforward by calling pthread_testcancel is both function
start. Although it would be simpler to call CANCELLATION_P directly, I
decided to add an internal pthread_testcancel alias and use it to export
less internal implementation on such function. A possible change on
how pthread_testcancel is internally implemented would lead to either
continue to force use CANCELLATION_P or to adjust its every use.
GLIBC testcase also does have tests for uncontended cases, test-cancel12
and test-cancel14.c, however both are flawed by adding another
cancellation point just after thread pthread_cleanup_pop:
47 static void *
48 tf (void *arg)
49 {
50 pthread_cleanup_push (cleanup, NULL);
51
52 int e = pthread_barrier_wait (&bar);
53 if (e != 0 && e != PTHREAD_BARRIER_SERIAL_THREAD)
54 {
55 puts ("tf: 1st barrier_wait failed");
56 exit (1);
57 }
58
59 /* This call should block and be cancelable. */
60 sem_wait (&sem);
61
62 pthread_cleanup_pop (0);
63
64 puts ("sem_wait returned");
65
66 return NULL;
67 }
So sem_{timed}wait does not act on cancellation, pthread_cleanup_pop executes
'cleanup' and then 'puts' acts on cancellation. Since pthread_cleanup_pop
removed the clean-up handler, it will ran only once and thus it won't accuse
an error to indicate sem_wait has not acted on the cancellation signal.
This patch also fixes this behavior by removing the cancellation point 'puts'.
It also adds some cleanup on all sem_{timed}wait cancel tests.
It partially fixes BZ #18243. Checked on x86_64.

nptl: Consolidate sem_open implementations
Current sparc32 sem_open and default one only differ on: 1. Default one contains a 'futex_supports_pshared' check. 2. sem.newsem.pad is initialized to zero. This patch removes sparc32 and sparc32v9 sem_open arch specific implementation and instead set sparc32 to use nptl default one. Using 1. is fine since it should always evaluate 0 for Linux (an optimized away by the compiler). Adding 2. to default implementation should be ok since 'pad' field is used mainly on sparc32 code. I checked on i686 and checked a sparc32v9 build. * nptl/sem_open.c (sem_open): Init pad value to 0. * sysdeps/sparc/sparc32/sem_open.c: Remove file. * sysdeps/sparc/sparc32/sparcv9/sem_open.c: Likewise. |

Remove the ptw-% patterns
Nothing depends on the PTW macro anymore, so the mechanism to define PTW for recompliations of libc routines is no longer needed. The source files are still recompiled for the nptl directory, just without the “ptw-” prefix. (Reducing the number of pattern rules in sysd-rules is critical for improving make performance.) |

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal fork callbacks (and they should not), so statically interposed mallocs lead to link failures because the strong reference from fork pulls in glibc's malloc, resulting in multiple definitions of malloc-related symbols. |

nptl: Avoid expected SIGALRM in most tests [BZ #20432]
Before this change, several tests did not detect early deadlocks because they used SIGALRM as the expected signal, and they ran for the full default TIMEOUT seconds. This commit adds a new delayed_exit function to the test skeleton, along with several error-checking wrappers to pthread functions. Additional error checking is introduced into several tests. |

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the (fixed) default stack cache size, allocated TLS variables are never freed, so the test coverage for tst-tls3-malloc is less than complete. This change increases the thread stack size for tst-tls3-malloc only, to make sure thread stacks and TLS variables are freed. |

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer. There is no external location to store the original (unaligned) pointer, and this commit increases the allocation size to store the pointer at a fixed location relative to the TCB pointer. The manual alignment means that some space goes unused which was previously made available for subsequent allocations. However, in the TLS_DTV_AT_TP case, the manual alignment code avoids aligning the pre-TCB to the TLS block alignment. (Even while using memalign, the allocation had some unused padding in front.) This concludes the removal of memalign calls from the TLS code, and the new tst-tls3-malloc test verifies that only core malloc routines are used. |

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t now includes the pointer which should be freed. Due to padding, the size of dtv_t does not increase. To avoid using memalign, the new allocate_dtv_entry function allocates a sufficiently large buffer so that a sub-buffer can be found in it which starts with an aligned pointer. Both the aligned and original pointers are kept, the latter for calling free later. |

Add pretty printers for the NPTL lock types
This patch adds pretty printers for the following NPTL types: - pthread_mutex_t - pthread_mutexattr_t - pthread_cond_t - pthread_condattr_t - pthread_rwlock_t - pthread_rwlockattr_t To load the pretty printers into your gdb session, do the following: python import sys sys.path.insert(0, '/path/to/glibc/build/nptl/pretty-printers') end source /path/to/glibc/source/pretty-printers/nptl-printers.py You can check which printers are registered and enabled by issuing the 'info pretty-printer' gdb command. Printers should trigger automatically when trying to print a variable of one of the types mentioned above. The printers are architecture-independent, and were manually tested on both the gdb CLI and Eclipse CDT. In order to work, the printers need to know the values of various flags that are scattered throughout pthread.h and pthreadP.h as enums and #defines. Since replicating these constants in the printers file itself would create a maintenance burden, I wrote a script called gen-py-const.awk that Makerules uses to extract the constants. This script is pretty much the same as gen-as-const.awk, except it doesn't cast the constant values to 'long' and is thorougly documented. The constants need only to be enumerated in a .pysym file, which is then referenced by a Make variable called gen-py-const-headers. As for the install directory, I discussed this with Mike Frysinger and Siddhesh Poyarekar, and we agreed that it can be handled in a separate patch, and it shouldn't block merging of this one. In addition, I've written a series of test cases for the pretty printers. Each lock type (mutex, condvar and rwlock) has two test programs, one for itself and other for its related 'attributes' object. Each test program in turn has a PExpect-based Python script that drives gdb and compares its output to the expected printer's. The tests run on the glibc host, which is assumed to have both gdb and PExpect; if either is absent the tests will fail with code 77 (UNSUPPORTED). For cross-testing you should use cross-test-ssh.sh as test-wrapper. I've tested the printers on both a native build and a cross build using a Beaglebone Black, with the build system's filesystem shared with the board through NFS. Finally, I've written a README that explains all this and more. Hopefully this should be good to go in now. Thanks. ChangeLog: 2016-07-04 Martin Galvan <martin.galvan@tallertechnologies.com> * Makeconfig (build-hardcoded-path-in-tests): Set to 'yes' for shared builds if tests-need-hardcoded-path is defined.

Fix robust mutex daedlock [BZ #20263]
In Linux/ARM environment, a robust mutex can't catch the timeout result when it is already owned by other thread and requests to try lock with a specific time value(pthread_mutex_timedlock). The futex already returns the ETIMEDOUT result but there is no check the return value and it makes a deadlock. * nptl/lowlevelrobustlock.c: Implement ETIMEDOUT logic. |

nptl: Add more coverage in tst-cancel4
This patch adds early cancel test for open syscall through a FIFO (thus makign subsequent call to open block until the other end is also opened). It also cleanup the sigpause tests by using sigpause along with SIGINT instead of __xpg_sigpause and SIGCANCEL. Since the idea is just to test the cancellation handling there is no need to expose internal glibc implementation details to the test through pthreadP.h inclusion. Tested x86_64. * nptl/tst-cancel4-common.c (do_test): Add temporary fifo creation. * nptl/tst-cancel4-common.h (fifoname): New variable. (fifofd): Likewise.

nptl: Add sendmmsg and recvmmsg cancellation tests
This patch adds cancellation tests for both sendmmsg and recvmmsg
syscalls. Since for some system configuration (x86_64/i686 on
older kernels and non-Linux platforms), the tests are added as
two independent that report as unsupported if the syscall is not
presented.
Both new tests uses the already tst-cancel4.c code, which as moved
to a common tst-cancel4-common{.c,h} files.
Tested on x86_64 and i686.

Remove __ASSUME_FUTEX_LOCK_PI
This patch removes __ASSUME_FUTEX_LOCK_PI usage and assumes that
kernel will correctly return if it supports or not
futex_atomic_cmpxchg_inatomic.
Current PI mutex code already has runtime support by calling
prio_inherit_missing and returns ENOTSUP if the futex operation fails
at initialization (it issues a FUTEX_UNLOCK_PI futex operation).
Also, current minimum supported kernel (v3.2) will return ENOSYS if
futex_atomic_cmpxchg_inatomic is not supported in the system:
kernel/futex.c:
2628 long do_futex(u32 __user *uaddr, int op, u32 val, ktime_t *timeout,
2629 u32 __user *uaddr2, u32 val2, u32 val3)
2630 {
2631 int ret = -ENOSYS, cmd = op & FUTEX_CMD_MASK;
[...]
2667 case FUTEX_UNLOCK_PI:
2668 if (futex_cmpxchg_enabled)
2669 ret = futex_unlock_pi(uaddr, flags);
[...]
2686 return ret;
2687 }
The futex_cmpxchg_enabled is initialized by calling cmpxchg_futex_value_locked,
which calls futex_atomic_cmpxchg_inatomic.
For ARM futex_atomic_cmpxchg_inatomic will be either defined (if both
CONFIG_CPU_USE_DOMAINS and CONFIG_SMP are not defined) or use the
default generic implementation that returns ENOSYS.
For m68k is uses the default generic implementation.
For mips futex_atomic_cmpxchg_inatomic will return ENOSYS if cpu has no
'cpu_has_llsc' support (defined by each chip supporte inside kernel).
For sparc, 32-bit kernel will just use default generic implementation,
while 64-bit kernel has support.
Tested on ARM (v3.8 kernel) and x86_64.

Revert {send,sendm,recv,recvm}msg conformance changes
After some discussion in libc-alpha about this POSIX compliance fix, I see
that GLIBC should indeed revert back to previous definition of msghdr and
cmsghdr and implementation of sendmsg, recvmsg, sendmmsg, recvmmsg due some
reasons:
* The possible issue where the syscalls wrapper add the compatibility
layer is quite limited in scope and range. And kernel current
also add some limits to the values on the internal msghdr and
cmsghdr fields:
- msghdr::msg_iovlen larger than UIO_MAXIOV (1024) returns
EMSGSIZE.
- msghdr::msg_controllen larger than INT_MAX returns ENOBUFS.
* There is a small performance hit for recvmsg/sendmsg/recmmsg which
is neglectable, but it is a big hit for sendmmsg since now instead
of calling the syscall for the packed structure, GLIBC is calling
multiple sendmsg. This defeat the very existence of the syscall.
* It currently breaks libsanitizer build on GCC [1] (I fixed on compiler-rt).
However the fix is incomplete because it does add any runtime check
since libsanitizer currently does not have any facility to intercept
symbols with multiple version [2].
This, along with incorret dlsym/dlvsym return for versioned symbol due
another bug [3], makes hard to interpose versioned symbols.
Also, current approach of fixing GCC PR#71445 leads to half-baked
solutions without versioned symbol interposing.
This patch basically reverts commits

network: recvmsg and sendmsg standard compliance (BZ#16919)
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively. However Linux defines it as both size_t and for 64-bit it requires some adjustments to make the functions standard compliance. This patch fixes it by creating a temporary header and zeroing the pad fields for 64-bits architecture where size of size_t exceeds the size of the int. Also the new recvmsg and sendmsg implementation is only added on libc, with libpthread only containing a compat symbol. Tested on x86_64, i686, aarch64, armhf, and powerpc64le. * conform/data/sys/socket.h-data (msghdr.msg_iovlen): Remove xfail- and change to correct expected type. (msghdr.msg_controllen): Likewise.

Fix tst-cancel17/tst-cancelx17, which sometimes segfaults while exiting.
The testcase tst-cancel[x]17 ends sometimes with a segmentation fault. This happens in one of 10000 cases. Then the real testcase has already exited with success and returned from do_test(). The segmentation fault occurs after returning from main in _dl_fini(). In those cases, the aio_read(&a) was not canceled because the read request was already in progress. In the meanwhile aio_write(ap) wrote something to the pipe and the read request is able to read the requested byte. The read request hasn't finished before returning from do_test(). After it finishes, it writes the return value and error code from the read syscall to the struct aiocb a, which lies on the stack of do_test. The stack of the subsequent function call of _dl_fini or _dl_sort_fini, which is inlined in _dl_fini is corrupted. In case of S390, it reads a zero and decrements it by 1: unsigned int k = nmaps - 1; struct link_map **runp = maps[k]->l_initfini; The load from unmapped memory leads to the segmentation fault. The stack corruption also happens on other architectures. I saw them e.g. on x86 and ppc, too. This patch adds an aio_suspend call to ensure, that the read request is finished before returning from do_test(). ChangeLog: * nptl/tst-cancel17.c (do_test): Wait for finishing aio_read(&a). |

New pthread_barrier algorithm to fulfill barrier destruction requirements.
The previous barrier implementation did not fulfill the POSIX requirements for when a barrier can be destroyed. Specifically, it was possible that threads that haven't noticed yet that their round is complete still access the barrier's memory, and that those accesses can happen after the barrier has been legally destroyed. The new algorithm does not have this issue, and it avoids using a lock internally. |

Do not violate mutex destruction requirements.
POSIX and C++11 require that a thread can destroy a mutex if no other thread owns the mutex, is blocked on the mutex, or will try to acquire it in the future. After destroying the mutex, it can reuse or unmap the underlying memory. Thus, we must not access a mutex' memory after releasing it. Currently, we can load the private flag after releasing the mutex, which is fixed by this patch. See https://sourceware.org/bugzilla/show_bug.cgi?id=13690 for more background. We need to call futex_wake on the lock after releasing it, however. This is by design, and can lead to spurious wake-ups on unrelated futex words (e.g., when the mutex memory is reused for another mutex). This behavior is documented in the glibc-internal futex API and in recent drafts of the Linux kernel's futex documentation (see the draft_futex branch of git://git.kernel.org/pub/scm/docs/man-pages/man-pages.git). |

nptl: Fix racy pipe closing in tst-cancel{20,21}
The tst-cancel20 open two pipes and creates a thread which blocks reading the first pipe. It then issues a signal to activate the signal handler which in turn blocks reading the second pipe end. Finally the cancellation cleanup-up handlers are tested by first closing the all the pipes ends and issuing a pthread_cancel. The tst-cancel21 have a similar behavior, but use an extra fork after the test itself. The race condition occurs if the cancellation handling acts after the pipe close: in this case read will return EOF (indicating side-effects) and thus the cancellation must not act. However current GLIBC cancellation behavior acts regardless the syscalls returns with sid-effects. This patch adjust the test by moving the pipe closing after the cancellation handling. This avoid spurious cancellation if the case of the race described. Checked on x86_64 and i386. * nptl/tst-cancel20.c (do_one_test): Move the pipe closing after pthread_join. * nptl/tst-cancel21.c (tf): Likewise. |

Remove CPU set size checking from affinity functions [BZ #19143]
With current kernel versions, the check does not reliably detect that
unavailable CPUs are requested, for these reasons:
(1) The kernel will silently ignore non-allowed CPUs, that is, CPUs
which are physically present but disallowed for the thread
based on system configuration.
(2) Similarly, CPU bits which lack an online CPU (possible CPUs)
are ignored.
(3) The existing probing code assumes that the CPU mask size is a
power of two and at least 1024. Neither has it to be a power
of two, nor is the minimum possible value 1024, so the value
determined is often too large. This means that the CPU set
size check in glibc accepts CPU bits beyond the actual hard
system limit.
(4) Future kernel versions may not even have a fixed CPU set size.
After the removal of the probing code, the kernel still returns
EINVAL if no CPU in the requested set remains which can run the
thread after the affinity change.
Applications which care about the exact affinity mask will have
to query it using sched_getaffinity after setting it. Due to the
effects described above, this commit does not change this.
The new tests supersede tst-getcpu, which is removed. This
addresses bug 19164 because the new tests allocate CPU sets
dynamically.

Convert miscellaneous function definitions to prototype style.
This patch converts various miscellaneous functions definitions in glibc, found with grep and not covered by my previous scripted conversions, from old-style K&R to prototype-style. These changes were made manually. This is not necessarily exhaustive as formatting variants may have prevented my grep from finding some such definitions. Regarding the changes to files from GMP, they may originally have been omitted when removing __STDC__ conditionals because of the files coming from another package, but (a) GMP no longer has __STDC__ conditionals there anyway and (b) we don't try to keep these files verbatim in sync with GMP (and there are licensing differences), so making the change to them in glibc seems reasonable.

Convert 113 more function definitions to prototype style (files with assertions).
This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

Convert 69 more function definitions to prototype style (line wrap cases).
This automatically-generated patch converts 69 function definitions in glibc from old-style K&R to prototype-style. This patch, covering both sysdeps and non-sysdeps files, deals with cases where the prototype needed to be wrapped over more than one line. Otherwise, exclusions and caveats are as for <https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00599.html>.

Convert 703 function definitions to prototype style.
This automatically-generated patch converts 703 function definitions in glibc from old-style K&R to prototype-style. This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.
