2002-08-07Changed my mind. Keep this separate.Eric Andersen
-Erik
2002-08-07Rewrite getenvEric Andersen
2002-08-07rework getopt. no read need to split this one up sinceEric Andersen
the parts are so tightly coupled.
2002-08-07Apply integer overflow security fix for "CERT Advisory CA-2002-25 IntegerEric Andersen
Overflow In XDR Library" http://www.cert.org/advisories/CA-2002-25.html Patch from Solar Designer <solar@openwall.com>.
2002-08-07Per suggestion from Miles Bader, move calloc.c to libc/stdlib.Eric Andersen
Also, Manuel notices that I forgot to check for when nmemb=0, which would result in a segfault, so fix that case as well. -Erik
2002-08-06Fixup the last missing pieces of thread lockingEric Andersen
-Erik
2002-08-06Rework RPC code once again. By default, only enable theEric Andersen
stuff needed for NFS mounts, rsh, and similar. -Erik
2002-08-06Changed fflush() behavior to no-op for r/w streams in read-mode.Manuel Novoa III
This falls under undefined behavior wrt ANSI/ISO C99, but SUSv3 seems to treat it as a no-op and it occurs in some apps. Fixed a problem with _stdio_fwrite() not checking for underlying write() failures. Fixed both _stdio_fwrite() and _stdio_fread() to make sure that the putc and getc macros were disabled if the stream was in and error state. The above changes should take care of a problem initially reported by "Steven J. Hill" <sjhill@realitydiluted.com>.
2002-08-06Unify calloc (its the same thing regardless of the underlyingEric Andersen
malloc implementation). Fix problem reported to bugtraq about problems with integer overflow that can occur during the computation of the memory region size by calloc (and similar functions) which could result in a subsequent buffer overflow. -Erik
2002-08-06Just in case, crash if somehow `exit' returns anywaysEric Andersen
-Erik
2002-08-03A couple of little cleanups I forgot to check in.Manuel Novoa III
2002-08-03When DODEBUG and HAS_WCHAR were enabled and HAS_LOCALE was disabled,Eric Andersen
wchar.c wouldn't compile: wchar.c: In function `__mbsnrtowcs': wchar.c:631: `__ctype_encoding_7_bit' undeclared (first use in this function) This fixes it by keeping the locale specific asserts hidden when not relevant. -Erik
2002-08-01Use MALLOC_REALLOC_MIN_FREE_SIZE.Miles Bader
2002-08-01(MALLOC_REALLOC_MIN_FREE_SIZE): New macro.Miles Bader
Enable debugging if MALLOC_DEBUGGING is defined.
2002-08-01(HEAP_MIN_SIZE): New macro.Miles Bader
(HEAP_MIN_FREE_AREA_SIZE): Increase size. Enable debugging if HEAP_DEBUGGING is defined.
2002-08-01Joseph Chiu <josephc@idealab.com> found an off-by-one bug. oops!Eric Andersen
2002-07-31In the allocate-and-copy case, don't include the malloc header in ourMiles Bader
size calculations.
2002-07-31Update debugging printfs.Miles Bader
2002-07-31Per discussion on the mailing list, simply vfork -> fork mapping to only applyEric Andersen
iff we do not have vfork available, which is simpler and more reasonable. -Erik
2002-07-31Patch from Martin Proulx <mproulx@okiok.com> to fix i960Eric Andersen
create_module() support.
2002-07-31Account for MALLOC_HEADER_SIZE when calculating new size.Miles Bader
2002-07-31Use MALLOC_HEADER_SIZE.Miles Bader
2002-07-31(MALLOC_HEADER_SIZE): New macro.Miles Bader
(MALLOC_BASE, MALLOC_ADDR): Use it.
2002-07-30Make sure NEW_SIZE is a multiple of HEAP_GRANULARITY.Miles Bader
Calculate amount freed when shrinking correctly.
2002-07-30Update the size of grown/shrunk allocations.Miles Bader
MALLOC_SET_SIZE now takes the user-address rather than the base-address.
2002-07-30MALLOC_SET_SIZE now takes the user-address rather than the base-address.Miles Bader
2002-07-30Define MALLOC_SET_SIZE to take the user-address rather than the base-address.Miles Bader
2002-07-30Implement shrinking.Miles Bader
Fix bug when growing an allocation. Use new malloc header macros.
2002-07-30Use new malloc header macros.Miles Bader
2002-07-30Add macros to abstract the malloc header format a bit.Miles Bader
2002-07-27Oops. I accidentally omitted the actual mknod() function.Eric Andersen
-Erik
2002-07-26Ok, I get it. sjhill kept adding the 'find' command sinceEric Andersen
include/sgidefs.h wasn't getting scrubbed. Fix it so this symlink gets properly scrubbed, even for mipsel. -Erik
2002-07-26The __set_errno macro _must_ match that defined in include/bits/errno.h. WeEric Andersen
can't tack in the return -1 since then when people include errno.h, the return -1 mysteriously vanishes... Setting the __set_errno back and restoring the 'return -1;' calls to each _syscall[0-n] macro makes mips syscalls work again. -Erik
2002-07-25ldso specific syscalls and userspace syscalls all in one file now."Steven J. Hill"
2002-07-25Implement syscall() for armEric Andersen
-Erik
2002-07-25Size tweaks.Miles Bader
2002-07-25Miscellaneous tidying-up.Miles Bader
2002-07-25Redo the locking, so that it may actually work. Now locking is done atMiles Bader
the malloc/free level, not within the heap abstraction, and there's a separate lock to control sbrk access. Also, get rid of the separate `unmap_free_area' function in free.c, and just put the code in the `free' function directly, which saves a bunch of space (even compared to using an inline function) for some reason.
2002-07-24Add support for people calling syscall()Eric Andersen
-Erik
2002-07-24Remove source files that, well, no longer exist :)."Steven J. Hill"
2002-07-24Factor out some common code sequences into inline functions.Miles Bader
2002-07-24Misc small cleanups.Miles Bader
2002-07-24Remove, since it's entirely incorrectMiles Bader
2002-07-23* Automatically try to unmap heap free-areas when they get very big.Miles Bader
* Instead of using mmap/munmap directly for large allocations, just use the heap for everything (this is reasonable now that heap memory can be unmapped). * Use sbrk instead of mmap/munmap on systems with an MMU.
2002-07-22Add some syscalls which I moved out of syscalls.cEric Andersen
-Erik
2002-07-22Rework syscall handling. Rewrite syscall handlers for x86 and ARM.Eric Andersen
Prepare to kill the UNIFIED_SYSCALL option and instead have it be a per arch thing that is either enabled or not for that arch. -Erik
2002-07-19Doc fix.Miles Bader
2002-07-19Rename mutex stuff to use heap-specific names.Miles Bader
Doc fix.
2002-07-18Miles Bader implemented a new mmap based malloc which is muchEric Andersen
smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles!
2002-07-16Fix from "Gerhard Uttenthaler" <uttenthaler@ems-wuensche.com> soEric Andersen
that cfsetspeed would actually be compiled in.
