b2a79f62 - selftests/mm: virtual_address_range: unmap chunks after validation

Tue, 14 Jan 2025 16:06:46 +0000

selftests/mm: virtual_address_range: unmap chunks after validationFor each accessed chunk a PTE is created. More than 1GiB of PTEs is usedin this way. Remove each PTE after validating a chunk to reduce peakmemory usage.It is important to only unmap memory that previously mmap()ed, asunmapping other mappings like the stack, heap or executable mappings willcrash the process.The mappings read from /proc/self/maps and the return values from mmap()don't allow a simple correlation due to merging and no guaranteed order. To correlate the pointers and mappings use prctl(PR_SET_VMA_ANON_NAME). While it introduces a test dependency, other alternatives would introduceruntime or development overhead.Link: https://lkml.kernel.org/r/20250114-virtual_address_range-tests-v4-2-6fd7269934a5@linutronix.deFixes: 010409649885 ("selftests/mm: confirm VA exhaustion without reliance on correctness of mmap()")Signed-off-by: Thomas Weißschuh Acked-by: David Hildenbrand Cc: Anshuman Khandual Cc: Dev Jain Cc: kernel test robot Cc: Shuah Khan (Samsung OSG) Cc: Thomas Gleixner Signed-off-by: Andrew Morton List of files: /linux-6.15/tools/testing/selftests/mm/config
