Fix is_zend_ptr() for huge blocks (#14626) is_zend_ptr() expected zend_mm_heap.huge_list to be circular, but it's in fact NULL-terminated. It could crash when at least one huge block exists and the ptr did not belong to any block.

Fix unspecified behaviour in zend_alloc in heap->limit computation Right-shifting a negative number is unspecified (i.e. implementation-defined) behaviour [1]. If we take a look at the generated assembly [2], we see that the wrong value is computed. Fix it by using Z_UL instead of Z_L. While we're at it, just change every occurrence of this pattern to use Z_UL instead of casting. [1] https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf §6.5.7.5 [2] https://godbolt.org/z/4Y1qKKjsh Closes GH-12613.

Add block size support for tracked_malloc (#11856) This does still deviate from USE_ZEND_ALLOC=0 in that we're not rounding up the size of the allocation to fixed sizes. Doing so would suppress some out-of-bounds errors checked by ASAN. Rounding up the size in _zend_mm_block_size would not be good either as it would break code like memset(ptr, 0 _zend_mm_block_size(ptr)).

Zend, ext/opcache: use PR_SET_VMA_ANON_NAME (Linux 5.17) (#8234) The new Linux 5.17 feature PR_SET_VMA_ANON_NAME can give names to anonymous private memory, see: https://lwn.net/Articles/867818/ It can be useful while debugging, to identify which portion of the process's memory belongs to which subsystem. This is how /proc/PID/maps can look like: 555ccd400000-555ccdc00000 r-xp 00000000 00:00 0 [anon:huge_code_pages] 7f6ec6600000-7f6ec6800000 rw-p 00000000 00:00 0 [anon:zend_alloc] The first mapping is the PHP executable copied to anonymous memory by option "opcache.huge_code_pages". The second one is a memory area for the "zend_alloc.h" memory allocator library. Unfortunately, it is not possible to give names to shared memory (MAP_SHARED), because Linux MAP_SHARED really maps /dev/zero (see shmem_zero_setup()), which makes madvise_vma_anon_name() believe this is a file mapping, failing the prctl() with EBADF.
