The default stack size for +musl libc is set to 80 KB whereas glibc has it set to 8 MB. This causes problems +when a large amount of memory is allocated on the stack. + +For example, opendkim allocates blocks of 64 KB multiple times, which causes +libmilter (and therefore opendkim) to crash. For now, a stack size of 256 KB +looks sufficient and makes opendkim stop crashing. + +Fixes https://bugs.alpinelinux.org/issues/6360 + +--- a/libmilter/libmilter.h ++++ b/libmilter/libmilter.h +@@ -127,10 +127,10 @@ + # define MI_SOCK_READ(s, b, l) read(s, b, l) + # define MI_SOCK_READ_FAIL(x) ((x) < 0) + # define MI_SOCK_WRITE(s, b, l) write(s, b, l) +- +-# define thread_create(ptid,wr,arg) pthread_create(ptid, NULL, wr, arg) + # define sthread_get_id() pthread_self() + ++extern int thread_create(pthread_t *ptid, void *(*wr) (void *), void *arg); ++ + typedef pthread_mutex_t smutex_t; + # define smutex_init(mp) (pthread_mutex_init(mp, NULL) == 0) + # define smutex_destroy(mp) (pthread_mutex_destroy(mp) == 0) +--- a/libmilter/main.c ++++ b/libmilter/main.c +@@ -16,6 +16,12 @@ + #include <fcntl.h> + #include <sys/stat.h> + ++int thread_create(pthread_t *ptid, void *(*wr) (void *), void *arg) { ++ pthread_attr_t attr; ++ pthread_attr_init(&attr); ++ pthread_attr_setstacksize(&attr,256*1024); ++ return pthread_create(ptid, &attr, wr, arg); ++} + + static smfiDesc_ptr smfi = NULL; |
