    name
    through local filesystem functions.
    

Problem summary

  • Crash in fp_get_path with the following
    stack trace:
    
    CRASH INFORMATION:
    CPU 16 CSA F0000000301ED600 at time of crash,
       error code
    for LEDs:
    70000000
    pvthread+142E00 STACK:
     00678B28 fp_get_path+000188 (0000000000000000,
    0000000000000000,
    F0000000301ED0C0, 0000000000000400  ?? )
     006784D8 fp_audit_svcbcopy+000018 (??)
     006B9354 ftrunc_common+000134 (??, ??)
    

Problem conclusion

  • In cn_fid(), set inode value from smbnode structure,
    and not dirseq structure
    In cifs_vget(), if an inode search results in a NULL vnode
    ptr, return appropriate error
    

Temporary fix
