## DISABLE_CANARY - Disables the use of canaries, improves performance
DISABLE_CANARY = -DDISABLE_CANARY=0

## Clear user chunks upon free
SANITIZE_CHUNKS = -DSANITIZE_CHUNKS=0

## Call verify_all_zones upon alloc/free, never reuse private zones
## Adds significant performance over head
FUZZ_MODE = -DFUZZ_MODE=0

## Permanently free any realloc'd chunk
PERM_FREE_REALLOC = -DPERM_FREE_REALLOC=0

## Enable memory tagging support. This will generate a random
## 1 byte tag per addressable chunk of memory. These tags can
## be retrieved and verified. This feature will likely interfere
## with ARM MTE and PAC. See MEMORY_TAGGING.md for more information
MEMORY_TAGGING = -DMEMORY_TAGGING=0

## Enable abort() when isoalloc can't gather enough entropy.
ABORT_NO_ENTROPY = -DABORT_NO_ENTROPY=1

## This enables Address Sanitizer support for manually
## poisoning and unpoisoning zones. It adds significant
## performance and memory overhead
## This is slow, and it's incompatible with other sanitizers
#ENABLE_ASAN = -fsanitize=address -DENABLE_ASAN=1

## Enable memory sanitizer to catch uninitialized reads.
## This is slow, and it's incompatible with other sanitizers
#ENABLE_MSAN = -fsanitize=memory -fsanitize-memory-track-origins -DENABLE_MSAN=1

## Enable undefined behavior sanitizer to catch undefined behavior.
## This is slow, and it's incompatible with other sanitizers
#ENABLE_UBSAN = -fsanitize=undefined

## Enable thread sanitizer. The slowest sanitizer of them
## all. But useful for finding thread related data race issues
## in the allocator in code paths that use atomic_flag
#ENABLE_TSAN = -fsanitize=thread

SANITIZER_SUPPORT = $(ENABLE_ASAN) $(ENABLE_MSAN) $(ENABLE_UBSAN) $(ENABLE_TSAN)

## Support for threads adds a performance overhead
## You can safely disable it here if you know your
## program does not require concurrent access
## to the IsoAlloc APIs
THREAD_SUPPORT = -DTHREAD_SUPPORT=1 -pthread

## By default IsoAlloc uses a pthread mutex to synchronize
## thread safe access to the root structure. By enabling this
## IsoAlloc will use a C11 atomic spinlock
USE_SPINLOCK = -DUSE_SPINLOCK=0

## This tells IsoAlloc to only start with 4 default zones.
## If you set it to 0 IsoAlloc will startup with 10. The
## performance penalty for setting it to 0 is a one time
## startup cost but more memory may be wasted. See the
## comments in iso_alloc_internal.h for modifying this
STARTUP_MEM_USAGE = -DSMALL_MEM_STARTUP=0

## Instructs the kernel (via mmap) to prepopulate
## page tables which will reduce page faults and
## sometimes improve performance. If you're using
## IsoAlloc for small short lived programs you probably
## want to disable this. This is ignored on MacOS
PRE_POPULATE_PAGES = -DPRE_POPULATE_PAGES=0

## Enable some functionality that like IsoAlloc internals
## for tests that need to verify security properties.
## Only test code should use this.
UNIT_TESTING = -DUNIT_TESTING=1

## Enable the malloc/free and new/delete hooks
MALLOC_HOOK = -DMALLOC_HOOK=1

## Use Huge pages for any allocation that is a multiple
## of 2 megabytes. See PERFORMANCE.md for additional info
HUGE_PAGES = -DHUGE_PAGES=1
THP_PAGES = -DTHP_PAGES=1

## Enable the built-in heap profiler. When this is enabled
## IsoAlloc will write a file to disk upon exit of the
## program. This file encodes the heap usage patterns of
## the target. This file can be consumed by the profiler
## CLI utility. See PROFILER.md for the format of this file
#HEAP_PROFILER = -DHEAP_PROFILER=1 -fno-omit-frame-pointer \
#				-fno-optimize-sibling-calls -ldl

## Enable CPU pinning support on a per-zone basis. This is
## a minor security feature which introduces an allocation
## isolation property that is defined by CPU core. See the
## README for more detailed information. This is Linux only
## and has negative performance implications
CPU_PIN = -DCPU_PIN=0
SCHED_GETCPU =

## Enable the allocation sanity feature. This works a lot
## like GWP-ASAN does. It samples calls to iso_alloc and
## randomly swaps them out for raw page allocations that
## are surrounded by guard pages. These pages are unmapped
## upon free. Much like GWP-ASAN this is designed to be
## used in production builds and should not incur too
## much of a performance penalty
ALLOC_SANITY = -DALLOC_SANITY=0

## Enable hooking of memcpy/memmove/memset to detect out of bounds
## r/w operations on chunks allocated with IsoAlloc. Does
## not require ALLOC_SANITY is enabled. On MacOS you need
## to set FORTIFY_SOURCE to 0. Leave these commented if
## you aren't enabling them.
MEMCPY_SANITY = -DMEMCPY_SANITY=0
MEMSET_SANITY = -DMEMSET_SANITY=0

## Enable the userfaultfd based uninitialized read detection
## feature. This samples calls to malloc, and allocates raw
## pages of memory with mmap which are registered with the
## userfaultfd subsystem. We detect uninitialized reads by
## looking for the first read access of that page before a
## previous call to write. Think of it as GWP-ASAN but for
## uninitialized reads. Enabling this feature does incur a
## performance penalty. This requires that both ALLOC_SANITY
## and THREAD_SUPPORT are enabled. Linux only
UNINIT_READ_SANITY = -DUNINIT_READ_SANITY=0

## By default IsoAlloc may select a zone that holds chunks
## that are larger than were requested. This is intended
## to reduce memory consumption and is only done for smaller
## sizes. Enabling this feature configures IsoAlloc to only
## use zones that are a perfect fit for the requested size
## once its been rounded up to an aligned size.
STRONG_SIZE_ISOLATION = -DSTRONG_SIZE_ISOLATION=0

## Enable a sampling mechanism that searches for references
## to a chunk currently being freed. The search only overwrites
## the first reference to that chunk because searching all
## zones is very slow.
UAF_PTR_PAGE = -DUAF_PTR_PAGE=0

## Verifies the free bit slot cache does not contain duplicate
## entries which might lead to IsoAlloc handing out an in-use
## chunk to a caller. This is a slow search that has a small
## performance penalty
VERIFY_FREE_BIT_SLOTS = -DVERIFY_FREE_BIT_SLOTS=0

## Randomizes the free bit slot list upon creation. This can
## impact perf. You can control the minimum size of the list
## to be randomized with MIN_RAND_FREELIST in conf.h
RANDOMIZE_FREELIST = -DRANDOMIZE_FREELIST=1

## Enable experimental features that are not guaranteed to
## compile, or introduce stability and performance bugs
EXPERIMENTAL = -DEXPERIMENTAL=0

## These control log, memory leak, and memory usage code
## In a release build they are all set to 0
DEBUG_LOG_FLAGS = -DDEBUG=1 -DLEAK_DETECTOR=1 -DMEM_USAGE=1

## On Android we use prctl to name mappings so they are
## visible in /proc/pid/maps - But the Android build does
## not use this Makefile. You want to modify Android.mk
NAMED_MAPPINGS = -DNAMED_MAPPINGS=0

## Abort when the allocator cannot return a valid chunk
ABORT_ON_NULL = -DABORT_ON_NULL=0

## Enable protection against misusing 0 sized allocations
NO_ZERO_ALLOCATIONS = -DNO_ZERO_ALLOCATIONS=1

## Enables mlock() on performance sensitive pages. For lower
## end devices with less memory you may want to disable this
USE_MLOCK = -DUSE_MLOCK=1

## When enabled the default library constructor and destructor
## will be used to initialize and tear down the library. If
## you disable this you can call iso_alloc_initialize and
## iso_alloc_destroy to perform the same functions. Note if
## you disable this you will want to enable ISO_DTOR_CLEANUP
AUTO_CTOR_DTOR = -DAUTO_CTOR_DTOR=1

## Unmap user and bitmap in the destructor. You probably
## don't want this as theres no guarantee the IsoAlloc
## destructor will be called last and other destructors
## may reference objects within these pages
ISO_DTOR_CLEANUP = -DISO_DTOR_CLEANUP=0

## Register a signal handler for SIGSEGV that inspects si_addr
## for an address managed by IsoAlloc. Optionally used when
## UAF_PTR_PAGE is enabled for better crash handling
SIGNAL_HANDLER = -DSIGNAL_HANDLER=0

## Enable AARCH64 / ARMv8.5a Memory Tagging Extension support
#ARM_MTE = -DARM_MTE=1 -march=armv8.5-a+memtag

## If you know your target will have an ARMv8.1-A or newer and
## supports Top Byte Ignore (TBI) then you want to enable this.
## (Currently unused)
ARM_TBI = 0

## Enables guard pages around big zone meta data. Big zones
## are zones with a size greater than SMALL_SIZE_MAX as defined
## in conf.h. Disabling this will save 2 pages per big zone
## allocation. On systems with pages > 4k this results in
## substantial memory usage
BIG_ZONE_META_DATA_GUARD = -DBIG_ZONE_META_DATA_GUARD=0

## Enables guard pages around big zone user pages. On systems
## with pages > 4k this results in substantial memory usage
BIG_ZONE_GUARD = -DBIG_ZONE_GUARD=0

## Ensures all big zone user data pages are marked PROT_NONE
## while on the free list to catch UAF. This is disabled because
## it incurs a syscall (mprotect) per call to free and again
## upon reuse to mark them R/W again.
PROTECT_FREE_BIG_ZONES = -DPROTECT_FREE_BIG_ZONES=0

## By default IsoAlloc will mask pointers to protect against
## certain memory disclosures. This can be beneficial but also
## incurs a small performance cost
MASK_PTRS = -DMASK_PTRS=1

## IsoAlloc uses ARM64 Neon instructions where possible. You can
## explicitly disable that here
DONT_USE_NEON = -DDONT_USE_NEON=1

## We start with the standard C++ specifics but giving
## the liberty to choose the gnu++* variants and/or
## higher than C++17
STDCXX=c++17

## Ditto but with C, now modern compilers support -std=c2x
