Description Pranith Kumar K 2015-12-07 02:22:18 UTC

+++ This bug was initially created as a clone of Bug #1288857 +++

Description of problem:
    fouh->len is accessed after 'node' is freed. Also rv is int where as
    fouh->len is uint32 comparison needs to be changed to ssize_t variables.

    fuse: use-after-free fix in fuse-bridge, revisited
    
    Prompted by the email exchange in gluster-devel between Oleksandr
    Natalenko, xavi, and soumyak, I looked at this because the fuse client
    on the longevity cluster has also been suffering from a serious memory
    leak for some time. (longevity cluster is currently running 3.7.6)
    
    The longevity cluster manifests the same kernel notifier loop terminated
    log message the Oleksandr sees, and some sample runs suggest that the
    length passed to the (sys_)write call is unexpectedly and abnormally large.
    
    Basically this fix
     a) uses correct types for len and rv,
     b) copies the len from potentially incorrectly aligned memory (in a
        way that should minimize potential performance issues related to
        accessing unaligned memory.)
     c) changes log level of the kernel notifier loop terminated message
     d) fixes a potential mutex lock/unlock issue
