Subject: ftruncate fails
Date: Mon, 8 Apr 2024 10:44:51 +0900 [thread overview]
Message-ID: <E7D462A2-EE93-4A57-9F15-8565EE1567F3@linux.dev> (raw)
Hi,
With a recent kernel I see below program fails (Bus error) if executed from 9p mounted directory, not with the local filesystem (Ext4).
#include <stdlib.h>
#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/syscall.h>
#include <linux/memfd.h>
int main() {
char filename[] = __FILE__"_tmpfile_XXXXXX";
int fd, size;
size = getpagesize();
fd = mkstemp(filename);
if (ftruncate(fd, size)) {
printf("error");
}
}
