performance/write-behind: initialize lock in wb-file before wb-file is set in fd-ctx.

2011-06-01T04:54:09+00:00

- Consider a combination of fuse->quick-read->read-ahead->wb->client.
    quick-read can do open-behind (open is returned as success even
    before it is issued to backend) and hence the fd can already be
    in the list of open fds of the inode. A flush call on some other
    fd opened on the same inode, will result in ra_flush issuing flush
    calls to all the fds opened on the same inode. This can result in
    wb_flush trying to hold a lock on non-initialized lock there by causing
    memory corruption.

BUG: 2346 (Log message enhancements in GlusterFS - phase 1)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2346

check the op_ret for less than zero in sp_create_cbk since posix can send negative values other than -1

2011-02-22T17:22:05+00:00

posix can send -ve values other than -1 in create:

op_ret = setgid_override (this, real_path, &gid);

        if (op_ret < 0) {
                goto out;
        }

In stat-prefetch we check op_ret only for -1 which results in function
proceeding and op_ret may become 0 due to other function calls in
sp_create_cbk, hence crashes in fuse.
