uMTP-Responder-v1.5.1

• Storage : new flags and modes :

  • "locked" flag support.

  • "removable" flag support.

• New dynamic/runtime commands (umtprd -cmd:COMMAND) :

  • "lock"/"unlock" commands to dynamically lock/unlock lockable storage.

    Examples:

    Unlock all locked storage (set with the 'locked' option in the configuration file) :

    umtprd -cmd:unlock

    Lock all lockable storage (set with the 'locked' option in the configuration file) :

    umtprd -cmd:lock

  • "addstorage"/"rmstorage" commands to dynamically add/remove storage.

    Examples:

    umtprd '-cmd:addstorage:/tmp Tmp rw'

    umtprd '-cmd:rmstorage:Tmp'

    Use double-quotes when arguments have spaces in them:

    umtprd '-cmd:addstorage:/path "My Path" rw,removable'

    umtprd '-cmd:rmstorage:"My Path"'

• Added umask configuration entry and fix permissions on send objects.

• USB 3.0 SuperSpeed support.

• Supports files rename at the MTP device side.

• New "firmware_version" configuration field : set the MTP device info value.

• Many fixes and improvements :

  • Fix inotify for root folders when using multiple storage.

  • Add guard to avoid storage from being added twice.

  • Update the file size information to the dataset when modifying the file content.

  • Check that fs handles db is valid before using it to get entries.

  • Security fix : Fix the invalid ".." setObjectPropValue access trick.

  • Fix deadlock when SendObject / GetObjectHandles fail.

  • Fix permissions on newly created folders.

  • Configuration file : realign user usb buffers size.

  • Internal : Remove redundant code and possible double closedir issue.
    (Fix segmentation fault with uClibc).

  • Reduce the default max usb read/write buffer size to 8KB.
    (This is required by some SoCs, e.g. the iMX series)

  Many thanks to all the contributors !
