| * Make use of gcc attributes in some standard include headers.Pedro F. Giffuni2015-04-063-73/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `nonnull' attribute specifies that some function parameters should be non-null pointers. This is very useful as it helps the compiler generate warnings on suspicious code and can also enable some small optimizations. Also start using 'alloc_size' attribute in the allocator functions. This is an initial step to better integrate our libc with the compiler: these attributes are fully supported by clang and they are also useful for the static analyzer. Note that due to some bogus internal procedure in the way gcc ports are built they may require updating if they were built before r280801.

* The current POSIX semaphore implementation stores the _has_waiters flagJohn Baldwin2014-10-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | in a separate word from the _count. This does not permit both items to be updated atomically in a portable manner. As a result, sem_post() must always perform a system call to safely clear _has_waiters. This change removes the _has_waiters field and instead uses the high bit of _count as the _has_waiters flag. A new umtx object type (_usem2) and two new umtx operations are added (SEM_WAIT2 and SEM_WAKE2) to implement these semantics. The older operations are still supported under the COMPAT_FREEBSD9/10 options. The POSIX semaphore API in libc has been updated to use the new implementation. Note that the new implementation is not compatible with the previous implementation. However, this only affects static binaries (which cannot be helped by symbol versioning). Binaries using a dynamic libc will continue to work fine. SEM_MAGIC has been bumped so that mismatched binaries will error rather than corrupting a shared semaphore. In addition, a padding field has been added to sem_t so that it remains the same size.

* HPET: create /dev/hpetN as a way to access HPET from userland.Rui Paulo2014-10-241-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, TSC is broken and special applications might benefit from memory mapping HPET and reading the registers to count time. Most often the main HPET counter is 32-bit only[1], so this only gives the application a 300 second window based on the default HPET interval. Other applications, such as Intel's DPDK, expect /dev/hpet to be present and use it to count time as well. Although we have an almost userland version of gettimeofday() which uses rdtsc in userland, it's not always possible to use it, depending on how broken the multi-socket hardware is. Install the acpi_hpet.h so that applications can use the HPET register definitions. [1] I haven't found a system where HPET's main counter uses more than 32 bit. There seems to be a discrepancy in the Intel documentation (claiming it's a 64-bit counter) and the actual implementation (a 32-bit counter in a 64-bit memory area).

* Roll back r271012 even more aggressively.Ed Schouten2014-09-051-1/+1
| | | | | | | | | | | | | | | | | | | I've looked at the GCC sources and I now understand what's going wrong. THe C11 keywords are simply nonexistent when using C++ mode. They are marked as C-only in the parser. This is absolutely impractical for multiple reasons: - The C11 keywords do not conflict with C++ naming rules. They all start with _[A-Z]. There is no reason to make them C-only. - It makes it practically impossible for people to use these keywords in C header files and expect them to work from within C++ sources. As I said in my previous commit message: GCC is by far the weirdest compiler that I've ever used. Notes: svn path=/head/; revision=271155
* Leave the C11 keywords alone when we have a recent version of GCC.Ed Schouten2014-09-031-1/+1
| | | | | | | | | | | | | | As GCC also gained support for the C11 keywords over time, we can patch up <sys/cdefs.h> to not define these anymore. This has the advantage that error messages for static assertions are printed natively and that _Alignas() will work with even a type outside of C11 mode. All C11 keywords are supported with GCC 4.7 and higher, with the exception of _Thread_local and _Generic. These are only supported as of GCC 4.9. Notes: svn path=/head/; revision=271012

* Add lock annotations to the header files of our threading libraries.Ed Schouten2014-09-011-27/+49
| | | | | | | | | | | | | | | | | | This change extends all of the functions present in the <pthread.h> and <threads.h> headers to have lock annotations. This will allow Clang to warn about the following: - Locking a function twice, - Unlocking a function without a mutex being locked, - Forgetting to unlock a mutex before returning, - Destroying or reinitializing a mutex that is currenty locked, - Using an unlocked mutex in combination with a condition variable. Enabling these annotations already allowed me to catch a bug in one of our userspace tools (r270749). Notes: svn path=/head/; revision=270943

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From http://www.isc.org/downloads/libbind/ The libbind functions have been separated from the BIND suite as of BIND 9.6.0. Originally from older versions of BIND, they have been continually maintained and improved but not installed by default with BIND 9. This standard resolver library contains the same historical functions and headers included with many Unix operating systems. In fact, most implementations are based on the same original code. At present, NetBSD maintains libbind code, now known as "netresolv". Notes: svn path=/vendor/resolver/dist/; revision=269610

* Fix some edge cases with rewinddir():John Baldwin2014-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | - In the unionfs case, opendir() and fdopendir() read the directory's full contents and cache it. This cache is not refreshed when rewinddir() is called, so rewinddir() will not notice updates to a directory. Fix this by splitting the code to fetch a directory's contents out of __opendir_common() into a new _filldir() function and call this from rewinddir() when operating on a unionfs directory. - If rewinddir() is called on a directory opened with fdopendir() before any directory entries are fetched, rewinddir() will not adjust the seek location of the backing file descriptor. If the file descriptor passed to fdopendir() had a non-zero offset, the rewinddir() will not rewind to the beginning. Fix this by always seeking back to 0 in rewinddir(). This means the dd_rewind hack can also be removed. While here, add missing locking to rewinddir().
