* MFC r229848:Ed Schouten2012-11-221-3/+4
| | | | | | | | | | | | | | | | | Add aligned_alloc(3). The C11 folks reinvented the wheel by introducing an aligned version of malloc(3) called aligned_alloc(3), instead of posix_memalign(3). Instead of returning the allocation by reference, it returns the address, just like malloc(3). I'm MFCing this now, as it seems aligned_alloc(3) is needed to make the new version of libc++ work, which was merged back to FreeBSD 9 in r243376.

| | | | | | | | | | | | | | | | | -g, by reverting r219139. The LLVM PR referenced in that revision was fixed in the mean time, and we imported a clang snapshot soon afterwards, so the temporary workaround of disabling clang's integrated assembler is no longer needed. In this particular case, using e.g. DEBUG_FLAGS=-g causes clang to output certain directives into assembly that our version of GNU as chokes on.

* Put in a temporary workaround for ctfmerge hanging on processingDimitry Andric2011-03-011-0/+4
| | | | | | | | | | | | | | | | | | | kernel.debug (or possibly other files), when WITH_CTF is active. This is caused by a bug in clang's integrated assembler, causing malloc to sometimes hang during initialization in statically linked executables that use threading, such as the copy of ctfmerge that is built during the bootstrap stage of buildworld. The bug has been submitted upstream: http://llvm.org/bugs/show_bug.cgi?id=9352 Note that you might have to rebuild and install libc first, to get your kernel build to finish, because the ctfmerge binary built during bootstrap is linked with your base system's copy of libc.a, which might already contain a bad copy of malloc.o.

* Integrate the new MPSAFE TTY layer to the FreeBSD operating system.Ed Schouten2008-08-201-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

* Significantly reduce the memory leak as noted in BUGS section forSean Farley2007-07-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

| | | | | | | | | | | | | | send strhash(3) off to sleep with the fishes. Nothing in our tree uses it. It has no documentation. It is nonstandard and in spite of the filename strhash.c and strhash.h, it lives in application namespace by providing compulsory global symbols hash_create()/hash_destroy()/hash_search()/ hash_traverse()/hash_purge()/hash_stats() regardless of whether you #include <strhash.h> or not. If it turns out that there is a huge application for this after all, I can repocopy it somewhere safer and we can revive it elsewhere. But please, not in libc! Notes: svn path=/head/; revision=121639

Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.
