      fs: buffer error in directory reads · 17756c7c
      Han-Wen Nienhuys authored
      Previously, if a DirStream.Next() call would return error, we would
      return the buffered data as well as the errno code in the same
      request.
      
      This would confuse the kernel, who interprets this as an invalid
      response, returning syscall.EIO to the caller.
      
      To fix this, also buffer the errno as overflow entry in the fileEntry
      struct. When we encounter an error, return thus far read entries with
      success. The following read contains just the error.
      
      For testing this properly, loopbackDirStream (which reads directory
      contents) must also buffer error returns.

      mount: add Options{RootStableAttr} field · 615a0a7e
      ZheNing Hu authored
      - provides an optional way to set e.g. Ino and/or Gen for
        the root directory when calling fs.Mount()
      - provides unit test cases
      - partial fix for #399

      forgot that it exists. Use it now.
      
      This will be important for DirectMount, as passing "fsname=xxx" to
      the mount syscall causes the kernel to reject with EINVAL and this
      message in dmesg:

      These were open-coded before. Pull them into the struct

      I'm doing this now as I'm about to add another option.

      fuse, fs: add DirectMount tests & DirectMountStrict option · 05c0aea6
      Jakob Unterwurzacher authored
      Reason for adding DirectMountStrict is making the DirectMount
      functionality testable, though it may have value for the user
      in some cases.
      
      Add defaultRawFileSystem & loopback tests for DirectMount
      and DirectMountStrict.
      
      The tests fail right now due to bugs in DirectMount that will be fixed
      shortly:
      
      	go-fuse/fuse$ sudo /usr/local/go/bin/go test -run TestDirectMount

      fuse: Increase MAX_KERNEL_WRITE to 1 MiB & enable CAP_MAX_PAGES · 265a3926
      Jakob Unterwurzacher authored
      Kernel 4.20 allows writes & reads up to 1 MiB (before: 128 kiB)
      via CAP_MAX_PAGES & MaxPages.
      
      Instead of exposing MaxPages in the API, we follow what libfuse
      does, and calculate MaxPages from MaxWrite (rounding up).
      
      Contrary to what libfuse does, we also set max_read to the same
      value as MaxWrite. This prevents reads getting larger than writes
      due to the rounding-up for MaxPages, which is unexpected. This
      also changes the default behavoir of go-fuse, which was 64 kiB
      writes, but 128 kiB for reads. Now it is 128 kiB for both.
      
      The tests are implemented in the fs package because it's
      easier there. They also test MaxReadAhead.
      
      Tested on Linux 4.19.0 and Linux 6.1.7 via all.bash,
      and on 6.1.7 also via the gocryptfs test suite.

      Make ReadDirPlus configurable · 915cf541
      Tamas Kerecsen authored
      When ReadDirPlus is enabled, the FUSE fs has to gather a lot of additional data for every file even if it won't be used (for example when the user is doing and 'ls' or a large glob). This can cause performance problems, so it should be possible to switch to the simple ReadDir behavior for file systems where this is a bottleneck.

      Make OSXFUSE handle timeouts the same way as Linux · d01fda7e
      Jille Timmermans authored
      OSXFUSE applies a 60-second timeout for file operations. This
      is inconsistent with how FUSE works on Linux, where operations
      last as long as the daemon is willing to let them run.
