read-only open causing file to be truncated with NFSv4/ganesha.
by Pradeep
Hello,
I'm seeing an issue with a specific application flow and with ganesha
server (2.6.5). Here is what the application does:
- fd1 = open (file1, O_WRONLY|O_CREAT|O_TRUNC)
Ganesha creates a state and stores the flags in fd->openflags (see
vfs_open2())
- write (fd1, ....)
- fd2 = open(file1, O_RDONLY)
Ganesha finds the state for the first open, finds the flags and calls
fsal_reopen2() with old and new flags OR'd together. This causes the file
to be truncated because the original open was done with O_TRUNC.
I don't see this behavior with kernel NFS or a local filesystem. Any
suggestions on fixing this? Here is a quick and dirty program to reproduce
it - you can see that the second stat prints zero as size with a mount from
Ganesha server.
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <unistd.h>
int main(int argc, char **argv)
{
char *fn = argv[1];
int fd;
char buf[1024];
struct stat stbuf;
int rc;
fd = open(fn, O_WRONLY|O_CREAT|O_TRUNC, 0666);
printf("open(%s) = %d\n", fn, fd);
ssize_t ret;
ret = write(fd, buf, sizeof(buf));
printf("write returned %ld\n", ret);
rc = stat(fn, &stbuf);
printf("size: %ld\n", stbuf.st_size);
int fd1;
fd1 = open(fn, O_RDONLY);
printf("open(%s) = %d\n", fn, fd1);
rc = stat(fn, &stbuf);
printf("size: %ld\n", stbuf.st_size);
}
Thanks,
Pradeep

Change in ffilz/nfs-ganesha[next]: status2 should not return FSAL_O_TRUNC
by GerritHub
From Sachin Punadikar <psachin(a)in.ibm.com>:
Sachin Punadikar has uploaded this change for review. ( https://review.gerrithub.io/430435
Change subject: status2 should not return FSAL_O_TRUNC
......................................................................
status2 should not return FSAL_O_TRUNC
"status2" call returns earlier open_flags. If earlier open was with
FSAL_O_TRUNC, then next open (reopen) truncates the file, due to ORing
of old open flags with new one. "status2" should not return FSAL_O_TRUNC
flag if it was set before.

watch streams in the hallways when rooms are full. This requires
speakers to consent to being recorded and streamed. If you plan to be a
speaker, please understand that by doing so you implicitly give consent
for your talk to be recorded and streamed. The recordings will be
published under the same license as all FOSDEM content (CC-BY).

Please test Ganesha 2.7.1 (rpc 1.7.1). Not everything has been
backported, even though I flagged stuff for backport to rpc 1.6
more than half a year ago. As I've already mentioned....
I've given up on Ganesha 2.6. I'm working on rebasing for 2.8.
