This option is enabled for a long time and I see no
useful case where we should be incompatible to glibc here.

The name was changed to include a trailing 'D' when it went into the
kernel.

The 0.9.31 release included a change to malloc-simple to request
uninitialized memory from noMMU kernels. Unfortunately, the corresponding
calloc() code assumed that memory returned by malloc() was already zeroed,
which leads to all kinds of nastiness.

Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use
it to get real uninitialized memory on no-mmu systems. This avoids a lot
of normally useless overhead involved in zeroing out all of the memory
(sometimes multiple times).

sed -i -e '/Experimentally off - /d' $(grep -rl "Experimentally off - " *)
sed -i -e '/^\/\*[[:space:]]*libc_hidden_proto(/d' $(grep -rl "libc_hidden_proto" *)
should be a nop

Appears to build fine (several .configs tried)

Thank you Chase Douglas for reporting it and for the patch.
|
|
remove a few duplicate includes of unistd.h
|
|
in string.h and strings.h. This caught unguarded string ops in
libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

trigger a buffer overflow in that case

things, and avoid potential deadlocks caused when a thread holding a uClibc
internal lock get canceled and terminates without releasing the lock. This
change also provides a single place, bits/uClibc_mutex.h, for thread libraries
to modify to change all instances of internal locking.

is a useless attempt

missing headers, other jump relocs removed

Dont forgive that length of munmap is "0" in current nommu.
This purpose cannot free memory area really.
It is a patch to work out a solution.
|
|
Only use MAP_SHARED when mmu-less.

Fix uninitialized pthread mutex used to lock the list of aligned
memory blocks.

Lea. It is about 2x faster than the old malloc-930716, and behave itself much
better -- it will properly release memory back to the system, and it uses a
combination of brk() for small allocations and mmap() for larger allocations.

simple and releases memory immediately when asked to do so.

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!

when folks do a malloc(0) using malloc-simple.

defining things to "0" in the disabled case to outright undefining them, lest
code that does an "#ifdef FOO" get inadvertantly triggered. Remove now
unneeded lines from Rules.mak which makes the command line smaller and avoids
redundancy (since this stuff is now pulled in via features.h).

Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less)
should update and recompile.
