I see a lot of places using the aarch64 macro but not all of them checking for _M_ARM64. I wonder if all code should always check both. Evgeny Karpov -- Many aarch64 macros are related only to Linux |

…STRINGS) A recursive OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS) call may happen if an out-of-memory error happens at the first callstack, and the dead-lock happens at the second callstack, because ossl_err_get_state_int calls OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS) although that call is currently already executing. At least on posix system this causes the process to freeze at this point, and must be avoided whatever it takes. The fix is using err_shelve_state around the critical region, which makes ossl_err_get_state_int return early and not call the recursive OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS). This can be reproduced with my error injection patch. The test vector has been validated on the master branch: $ ERROR_INJECT=1692279870 ../util/shlib_wrap.sh ./asn1parse-test ./corpora/asn1parse/027f6e82ba01d9db9a9167b83e56cc9f2c602550 ERROR_INJECT=1692279870 #0 0x7f280b42fef8 in __sanitizer_print_stack_trace ../../../../src/libsanitizer/asan/asan_stack.cpp:86 #1 0x5610a3f396b4 in my_malloc fuzz/test-corpus.c:114 #2 0x7f280a2eb94c in CRYPTO_malloc crypto/mem.c:177 #3 0x7f280a2dafdb in OPENSSL_LH_insert crypto/lhash/lhash.c:114 #4 0x7f280a1c87fe in err_load_strings crypto/err/err.c:264 #5 0x7f280a1c87fe in err_load_strings crypto/err/err.c:259 #6 0x7f280a1c87fe in ERR_load_strings_const crypto/err/err.c:301 #7 0x7f280a6f513b in ossl_err_load_PROV_strings providers/common/provider_err.c:233 #8 0x7f280a1cf015 in ossl_err_load_crypto_strings crypto/err/err_all.c:109 #9 0x7f280a2e9b8c in ossl_init_load_crypto_strings crypto/init.c:190 #10 0x7f280a2e9b8c in ossl_init_load_crypto_strings_ossl_ crypto/init.c:181 #11 0x7f2808cfbf67 (/lib/x86_64-linux-gnu/libc.so.6+0x99f67) #12 0x7f280a32301e in CRYPTO_THREAD_run_once crypto/threads_pthread.c:154 #13 0x7f280a2ea1da in OPENSSL_init_crypto crypto/init.c:553 #14 0x5610a3f38e2f in FuzzerInitialize fuzz/asn1parse.c:29 #15 0x5610a3f38783 in main fuzz/test-corpus.c:194 #16 0x7f2808c8bd8f (/lib/x86_64-linux-gnu/libc.so.6+0x29d8f) #17 0x7f2808c8be3f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x29e3f) openssl#18 0x5610a3f38d34 in _start (/home/runner/work/openssl/openssl/fuzz/asn1parse-test+0x3d34) AddressSanitizer:DEADLYSIGNAL ================================================================= ==27629==ERROR: AddressSanitizer: ABRT on unknown address 0x03e900006e23 (pc 0x7f2808cfbef8 bp 0x7f280b36afe0 sp 0x7ffd545b2460 T0) #0 0x7f2808cfbef8 (/lib/x86_64-linux-gnu/libc.so.6+0x99ef8) #1 0x7f280a32301e in CRYPTO_THREAD_run_once crypto/threads_pthread.c:154 #2 0x7f280a2ea1da in OPENSSL_init_crypto crypto/init.c:553 #3 0x7f280a1c935e in ossl_err_get_state_int crypto/err/err.c:705 #4 0x7f280a1cf1f9 in ERR_new crypto/err/err_blocks.c:20 #5 0x7f280a2eb9ac in CRYPTO_malloc crypto/mem.c:205 #6 0x7f280a2dafdb in OPENSSL_LH_insert crypto/lhash/lhash.c:114 #7 0x7f280a1c87fe in err_load_strings crypto/err/err.c:264 #8 0x7f280a1c87fe in err_load_strings crypto/err/err.c:259 #9 0x7f280a1c87fe in ERR_load_strings_const crypto/err/err.c:301 #10 0x7f280a6f513b in ossl_err_load_PROV_strings providers/common/provider_err.c:233 #11 0x7f280a1cf015 in ossl_err_load_crypto_strings crypto/err/err_all.c:109 #12 0x7f280a2e9b8c in ossl_init_load_crypto_strings crypto/init.c:190 #13 0x7f280a2e9b8c in ossl_init_load_crypto_strings_ossl_ crypto/init.c:181 #14 0x7f2808cfbf67 (/lib/x86_64-linux-gnu/libc.so.6+0x99f67) #15 0x7f280a32301e in CRYPTO_THREAD_run_once crypto/threads_pthread.c:154 #16 0x7f280a2ea1da in OPENSSL_init_crypto crypto/init.c:553 #17 0x5610a3f38e2f in FuzzerInitialize fuzz/asn1parse.c:29 openssl#18 0x5610a3f38783 in main fuzz/test-corpus.c:194 openssl#19 0x7f2808c8bd8f (/lib/x86_64-linux-gnu/libc.so.6+0x29d8f) openssl#20 0x7f2808c8be3f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x29e3f) openssl#21 0x5610a3f38d34 in _start (/home/runner/work/openssl/openssl/fuzz/asn1parse-test+0x3d34) AddressSanitizer can not provide additional info.
