This can overflow on systems with\n1GB hugepages, where computed test sizes may exceed INT_MAX.\n\nFor example, with 1GB hugepages and N=4, the test generates a 4GB\nallocation size. Storing this in int truncates the value, resulting\nin invalid sizes being passed to shmget() and subsequent failures\nsuch as EINVAL during shared memory attachment.\n\nUse size_t for size-related variables and update the corresponding\nprintf format specifier to correctly represent allocation sizes.\n\nFixes: 46640e176d (\"hugetlb: add new testcase hugeshmat05.c\")\nReported-by: Pavithra Prakash <pavrampu@linux.ibm.com>\nSigned-off-by: Sayali Patil <sayalip@linux.ibm.com>\n---\n testcases/kernel/mem/hugetlb/hugeshmat/hugeshmat05.c | 6 +++---\n 1 file changed, 3 insertions(+), 3 deletions(-)", "diff": "diff --git a/testcases/kernel/mem/hugetlb/hugeshmat/hugeshmat05.c b/testcases/kernel/mem/hugetlb/hugeshmat/hugeshmat05.c\nindex 3b2ae351c..eb8663f2c 100644\n--- a/testcases/kernel/mem/hugetlb/hugeshmat/hugeshmat05.c\n+++ b/testcases/kernel/mem/hugetlb/hugeshmat/hugeshmat05.c\n@@ -39,7 +39,7 @@ void setup(void)\n \thpage_size = SAFE_READ_MEMINFO(\"Hugepagesize:\") * 1024;\n }\n \n-void shm_test(int size)\n+void shm_test(size_t size)\n {\n \tint shmid;\n \tchar *shmaddr;\n@@ -56,7 +56,7 @@ void shm_test(int size)\n \t}\n \n \tshmaddr[0] = 1;\n-\ttst_res(TINFO, \"allocated %d huge bytes\", size);\n+\ttst_res(TINFO, \"allocated %zu huge bytes\", size);\n \n \tif (shmdt((const void *)shmaddr) != 0) {\n \t\tshmctl(shmid, IPC_RMID, NULL);\n@@ -70,7 +70,7 @@ static void test_hugeshmat(void)\n {\n \tunsigned int i;\n \n-\tconst int tst_sizes[] = {\n+\tconst size_t tst_sizes[] = {\n \t\tN * hpage_size - page_size,\n \t\tN * hpage_size - page_size - 1,\n \t\thpage_size,\n", "prefixes": [] }
