      fuse: Fix InodeRetrieveCache to retrieve data in chunks · 58dcd77a
      Kirill Smelkov authored
      It turned out that:
      
      1. Linux kernel cannot send data in chunks bigger than what was
         configured as MaxWrite on init, and
      
      2. if we ask for more, and that more, after capping to kernel write
         maxium, is more than configured MaxWrite, the kernel will simply drop
         NOTIFY_REPLY message. This, hopefully, will be fixed
      
      	https://marc.info/?l=linux-fsdevel&m=155000277921155&w=2
      
         but we cannot count on this fix to be present on older kernels, and
         even if it is there, we still won't get more than MaxWrite data.
      
      -> Rework InodeRetrieveCache to retrieve the data in chunks.
      
      NOTE1: we do not load users with this FUSE exchange details and instead
      of returning less content than requested, try to retrieve it all.
      
      NOTE2: without changes to fuse/server.go, added test will get stuck (see
      details in above link to linux-fsdevel patch).

      Don't crash when calling truncate(1) on a handle without a File. · 33711add
      Ed Schouten authored
      For all operations that can be applied on file descriptors, we have
      special treatment to permit the File to be nil. In that case, operations
      are called against the Node object instead.
      
      This check currently seems missing from SetAttr(), causing invocations
      of the truncate(1) command line tool to cause a crash:
      
              panic: runtime error: invalid memory address or nil pointer dereference
              [signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0xa30d0d]
