    nptl: ppc32: Fix Race conditions in pthread cancellation (BZ#12683)
    
    This patches adds the ppc32 modification required for the BZ#12683
    fix.  It basically removes the enable_asynccancel/disable_asynccancel
    function usage on code used on ppc32.

    nptl: x86_64: Fix Race conditions in pthread cancellation (BZ#12683)
    
    This patches adds the x86_64 modification required for the BZ#12683 fix.
    It basically removes the enable_asynccancel/disable_asynccancel function
    usage on code used on x86_64, provide a arch-specific symbol that
    contains global markers to be used in SIGCANCEL handler, and remove
    x86_64 assembly pthread conditional and semaphore code to use default
    one (that already contains the cancel call fixes).

    nptl: Fix Race conditions in pthread cancellation
    
    This patches fixes some race conditions in NPTL cancellation code by
    redefining how cancellable syscalls are defined and handled.  Current
    approach is to enable asynchronous cancellation prior to making the syscall
    and restore the previous cancellation type once the syscall returns.
    
    As decribed in BZ#12683, this approach shows 2 important problems:
    
    1. Cancellation can act after the syscall has returned from kernel, but
       before userspace saves the return value.  It might result in a resource
       leak if the syscall allocated a resource or a side effect (partial
       read/write), and there is no way to program handle it with cancellation
       handlers.
    
    2. If a signal is handled while the thread is blocked at a cancellable
       syscall, the entire signal handler runs with asynchronous cancellation
       enabled.  This can lead to issues if the signal handler call functions
       which are async-signal-safe but not async-cancel-safe.
    
    For cancellation to work correctly, there are 5 points at which the
    cancellation signal could arrive:
    
    1. Before the final testcancel before the syscall is made.
    2. Between the testcancel and the syscall.
    3. While the syscall is blocked and no side effects have yet taken place.
    4. While the syscall is blocked but with some side effects already having
       taken place (e.g. a partial read or write).
    5. After the syscall has returned.
    
    And GLIBC wants to act on cancellation in cases 1, 2, and 3 but not in case
    4 or 5.  The proposed solution follows:
    
    * Handling case 1 is trivial: do a conditional branch based on whether the
      thread has received a cancellation request;
    * Case 2 can be caught by the signal handler determining that the saved
      program counter (from the ucontext_t) is in some address range beginning
      just before the "testcancel" and ending with the syscall instruction.
    * In this case, except for certain syscalls that ALWAYS fail with EINTR
      even for non-interrupting signals, the kernel will reset the program
      counter to point at the syscall instruction during signal handling, so
      that the syscall is restarted when the signal handler returns. So, from
      the signal handler's standpoint, this looks the same as case 2, and thus
      it's taken care of.
    * In this case, the kernel cannot restart the syscall; when it's
      interrupted by a signal, the kernel must cause the syscall to return
      with whatever partial result it obtained (e.g. partial read or write).
    * In this case, the saved program counter points just after the syscall
      instruction, so the signal handler won't act on cancellation.
      This one is equal to 4. since the program counter is past the syscall
      instruction already.
    
    Another case that needs handling is syscalls that fail with EINTR even
    when the signal handler is non-interrupting. In this case, the syscall
    wrapper code can just check the cancellation flag when the errno result
    is EINTR, and act on cancellation if it's set.
    
    The proposed GLIBC adjustments are:
    
    1. Remove the enable_asynccancel/disable_asynccancel function usage in
       syscall definition and instead make them call a common symbol that will
       check if cancellation is enabled, call the arch-specific cancellable
       entry-point and cancel the thread when required.
    2. Provide a arch-specific symbol that contains global markers. These
       markers will be used in SIGCANCEL handler to check if the interruption
       has been called in a valid syscall and if the syscalls has been
       completed or not.
    3. Rewrite SIGCANCEL asynchronous handler to check for both cancelling type
       and if current IP from signal handler falls between the global markes
       and act accordingly.
    4. Adjust nptl/pthread_cancel.c to send an signal instead of acting
       directly. This avoid synchronization issues about updating the
       cancellation status and also focus the logic on signal handler and
       cancellation syscall code.
    5. Adjust pthread code to replace CANCEL_ASYNC/CANCEL_RESET calls to
       appropriated cancelable futex syscalls.
    6. Adjust libc code to replace LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET to
       appropriated cancelable syscalls.
    7. Adjust 'lowlevellock.h' arch-specific implementations to provide
       cancelable futex calls (used in libpthread code).
    
    This patch adds the proposed changes to NPTL and the changes required
    for powerpc64.

commit b0fd583ccce17c5994cd7f98c693dbffbab52f27
Author: Adhemerval Zanella <azanella@linux.vnet.ibm.com>
Date:   Sun Sep 28 08:46:23 2014 -0300

    Rewrite cancellation macros
    
    This patch changes the way cancellation entrypoints are defined to
    instead call the macro SYSCALL_CANCEL.  An usual cnacellation definition
    is defined as:
    
      if (SINGLE_THREAD_P)
        return INLINE_SYSCALL (syscall, NARGS, args...)
    
      int oldtype = LIBC_CANCEL_ASYNC ();
    
      return INLINE_SYSCALL (syscall, NARGS, args...)
    
      LIBC_CANCEL_RESET (oldtype);
    
    And it is rewrited as just:
    
      SYSCALL_CANCEL (syscall, args...)
    
    The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET explicit
    usage.

commit 031219cf728c2f3366d49401ba744d0ae79263d2
Author: Adhemerval Zanella <azanella@linux.vnet.ibm.com>
Date:   Wed Sep 24 21:52:07 2014 -0300

    nptl: x86_64: remove assembly implementation
    
    This patch removes the x86_64 assembly implementation for
    pthread_cond_timedwait, pthread_cond_wait, sem_timedwait, and sem_wait
    for upcoming BZ#12683 fix.  The fix require that cancellable futex calls
    to be called through __syscall_cancel.
    
    Although it not strictly require, the remove of the x86_64 specific
    implementation follows the rationale:
    
    1. The adjustments required to this fix is extensive (parameters
       save, functions calls, etc.) and there is little gain in keep an
       alternate implementation for x86_64 in term of maintanability.
    2. There is no pthread_cond benchmark that shows these implementations
       are more 'optimized' that what current compilers can produce using
       generic C code.
    3. The changes required also can change the exact gains this optimized is
       intended to provide.

commit 9d734e505bf491ac71c6f93b5fabf1d1cee16bba
Author: Adhemerval Zanella <azanella@linux.vnet.ibm.com>
Date:   Wed Sep 24 20:22:05 2014 -0300

    nptl: Fix testcases for new pthread cancellation mechanism
    
    With upcoming fix for BZ#12683, pthread cancellation does not act for:
    
    1. If syscall is blocked but with some side effects already having taken
       place (e.g. a partial read or write)
    2. After the syscall has returned.
    
    It is because program need to act on such cases (for instance, to avoid
    leak of allocated resources our handling partial read/write).
    
    This patches fixes the NPTL testcase that assumes the old behavior and
    also remove the tst-cancel-wrappers.sh test (which checks for symbols
    that does not exist anymore).

commit 9291df15154b43257e1a9cfd40f7d0b07298d101
Author: Adhemerval Zanella <azanella@linux.vnet.ibm.com>
Date:   Wed Sep 24 13:38:59 2014 -0300

    Use inline syscalls for non-cancellable versions
    
    This patch uses inline calls (through INLINE_SYSCALL macro) to define
    the non-cancellable functions macros to avoid use of the
    syscall_nocancel entrypoint.
