2002-11-27Honour malloc_junk ('J') with realloc(3), and fix page_dir shrink update.Thierry Deval
2002-11-25Warn if atexit(3) fails. Change some tabs to spaces. UseChad Loder
STDERR_FILENO instead of 2. OK millert@
2002-11-05thread safe libc -- 2nd try. OK miod@, millert@Marco S Hyman
Thanks to miod@ for m68k and vax fixes
2002-11-03back out previous patch.. there are still some vax/m68k issuesMarco S Hyman
2002-11-03libc changes for thread safety. Tested on:Marco S Hyman
alpha (millert@), i386 (marc@), m68k (millert@ and miod@), powerpc (drahn@ and dhartmei@), sparc (millert@ and marc@), sparc64 (marc@), and vax (millert@ and miod@). Thanks to millert@, miod@, and mickey@ for fixes along the way.

2002-02-16Part one of userland __P removal. Done with a simple regexp with some minor ↵Todd C. Miller
hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.
2002-01-23THREAD_UNLOCK() on error before returning; millert@ ok.Federico G. Schwindt
2001-12-05correct an alignment mis-conception for malloc(0) returned regions.Thierry Deval
OK deraadt@
2001-11-01remove dangling spaces and tabsMichael Shalayeff
2001-10-30mprotect allocations sized at 0 bytes. This will cause a fault for accessThierry Deval
to such, permitting them to be discovered, instead of exploited as the ssh crc insertion detector was. Idea by theo, written by tdeval.

2001-05-10Use madvise(MADV_FREE) to allow the 'h' option.Artur Grabowski
(the code was already there, just not enabled).

1999-11-10calloc() needs to be separate from malloc in case a user wants to haveTodd C. Miller
their own malloc() implementation.
1999-11-09Move calloc() into malloc.c and only zero out the area if malloc()Todd C. Miller
didn't do so for us. By default, malloc() zeros out the space it allocates but the programmer cannot rely on this as it is implementation- specific (and configurable via /etc/malloc.conf)
1999-09-16use writev() where possibleTheo de Raadt
1999-02-03wrong ret type for write define (millert@)David Leonard
1999-02-01malloc can't use write() if it fails very early, so use the unwrapped ↵David Leonard
syscall _thread_sys_write() if we are threaded
1998-11-20Add thread-safety to libc, so that libc_r will build (on i386 at least).David Leonard
All POSIX libc api now there (to P1003.1c/D10) (more md stuff is needed for other libc/arch/*) (setlogin is no longer a special syscall) Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS). Doc some re-entrant routines Add libc_r to intro(3) dig() uses some libc srcs and an extra -I was needed there. Add more md stuff to libc_r. Update includes for the pthreads api Update libc_r TODO
1998-08-06Don't enumerate every arch in the #if since all OpenBSD platforms use the ↵Todd C. Miller
same values for malloc_pageshift and malloc_minsize except for sparc
1998-06-28Oh fun, mucking about with files used on all archs.Dale S. Rahn
This is one of many places in the source that have #if defined("list all architectures") Is there some possible way to eliminate, reduce these or at least have a file that describes all occurrances so that when a new port is done this could be addressed. like the recent hppa port, does it need to take a look at this????
1998-01-02make mmap() return void *, add MAP_FAILEDTheo de Raadt
1997-08-23Change realloc(foo,0) to behave like malloc(0). Both now return a pointerPer Fogelstrom
to an object of size zero. This will allow testing on reallocs return value to determine if the operation was successful or not.
1997-08-22malloc_init() should try to not modify errnoTheo de Raadt
1997-07-02Use MALLOC_EXTRA_SANITY consistently (EXTRA_SANITY was used in many places)Todd C. Miller
sizeof *pt -> sizeof *px (point to same type of struct but looked wrong).
