sync_ctx->input is different than sync_ctx->file_input, where the statbuf was taken from (took a while to notice this :). Could you do the same for it?
(gdb) p sync_ctx->file_input->v_offset $8 = 142294527
The mbox size is larger than 142294527
But it crashes because fstat() returns a value smaller than that as the mbox's size. Maybe NFS returns some old size from cache? I don't really know how NFS caching usually works. If someone has any pointers (other than kernel sources :) it'd be helpful.
What OS are you using on NFS client side?
How about if you try running this little program, does it work:
/* gcc writetest.c -o writetest -Wall */ #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <sys/stat.h>
int main(void) { int fd = open("writetest.tmp", O_RDWR | O_CREAT | O_TRUNC, 0600); char buf[1024]; struct stat st; int x, ret;
if (fd < 0) {
perror("open()");
return 1;
}
fstat(fd, &st);
for (x = 0; x < 100; x++) {
ret = write(fd, buf, sizeof(buf));
if (ret != sizeof(buf)) {
perror("write()");
return 1;
}
}
fstat(fd, &st);
printf("size again: %ld vs. %d\n", st.st_size, 100*sizeof(buf));
ret = write(fd, buf, sizeof(buf));
if (ret != sizeof(buf)) {
perror("write()");
return 1;
}
fstat(fd, &st);
printf("size finally: %ld vs. %d\n", st.st_size, 101*sizeof(buf));
return 0;}
