fix changelog
commit 8cd51ca1387d499f3e37657d0429206c578a5a7e
Author: Daniel Micay <danielmicay@gmail.com>
Date: Fri Jul 19 11:23:44 2019 -0400
override local default to -fstack-protector-strong
This is a no-op on a toolchain compiled with the basic mitigations
enabled by default, so this is generally a no-op anywhere this project
is likely to be deployed. SSP has a very low performance cost so there's
little reason to avoid it, even though it also has zero value for this
code in practice. It would be great if one of the more modern approaches
was widely adopted, but unfortunately SSP is as good as it gets for
portable options. It doesn't provide any protection against external
writes to the stack data which is all that's really needed here.
ShadowCallStack is a great option for arm64, but it's substantially more
difficult to protect return addresses well on x86_64 due to the design of
the ISA and ABI.

use -fstack-clash-protection for completeness
This is a no-op for the current code and will likely remain that way so
there's no benefit but also no performance cost.

realloc: use copy_size to check for canaries
This avoids unnecessarily copying the canary when doing a realloc from a
small size to a large size. It also avoids trying to copy a non-existent
canary out of a zero-size allocation, which are memory protected.

fill CSPRNG caches lazily to speed up early init
commit a13db3fc686f093a781e137bd53f3b810fde4fce
Author: Daniel Micay <danielmicay@gmail.com>
Date: Mon Apr 15 06:29:57 2019 -0400
initialize size class CSPRNGs from init CSPRNG
This avoids making a huge number of getrandom system calls during
initialization. The init CSPRNG is unmapped before initialization
finishes and these are still reseeded from the OS. The purpose of the
independent CSPRNGs is simply to avoid the massive performance hit of
synchronization and there's no harm in doing it this way.
Keeping around the init CSPRNG and reseeding from it would defeat the
purpose of reseeding, and it isn't a measurable performance issue since
it can just be tuned to reseed less often.

commit d5c1bca9153d8f4a548eb3552ae20d9c8322e373
Author: Daniel Micay <danielmicay@gmail.com>
Date: Tue Apr 9 16:36:01 2019 -0400
use round-robin assignment to arenas
The initial implementation was a temporary hack rather than a serious
implementation of random arena selection. It may still make sense to
offer it but it should be implemented via the CSPRNG instead of this
silly hack. It would also make sense to offer dynamic load balancing,
particularly with sched_getcpu().
This results in a much more predictable spread across arenas. This is
one place where randomization probably isn't a great idea because it
makes the benefits of arenas unpredictable in programs not creating a
massive number of threads. The security benefits of randomization for
this are also quite small. It's not certain that randomization is even a
net win for security since it's not random enough and can result in a
more interesting mix of threads in the same arena for an attacker if
they're able to attempt multiple attacks.

implement the option of large size classes
This extends the size class scheme used for slab allocations to large
allocations. This drastically improves performance for many real world
programs using incremental realloc growth instead of using proper growth
factors. There are 4 size classes for every doubling in size, resulting
in a worst case of ~20% extra virtual memory being reserved and a huge
increase in performance for pathological cases. For example, growing
from 4MiB to 8MiB by calling realloc in increments of 32 bytes will only
need to do work beyond looking up the size 4 times instead of 1024 times
with 4096 byte granularity.

ignore pad argument to malloc_trim per glibc
The pad argument is only used by the main arena for sbrk in glibc, with
every other page size gap purged with MADV_DONTNEED. It makes more sense
to simply treat it as an ignored legacy parameter rather than trying to
come up with a sensible way to use it for keeping cached free slabs.
