2014-09-02tools: ffs-test: add compatibility code for old kernelsMichal Nazarewicz
If ffs-test is used with a kernel prior to 3.14, which do not support the new descriptors format, it will fail when trying to write the descriptors. Add a function that converts the new descriptors to the legacy ones and use it to retry writing the descriptors using the legacy format. Also add “-l” flag to ffs-test which will cause the tool to never try the new format and instead immediatelly try the legacy one. This should be useful to test whether parsing of the old format still works on given 3.14+ kernel. Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-09-02tools: ffs-test: convert to new descriptor formatMichal Nazarewicz
Since commit [ac8dde11: “Add flags to descriptors block”] functionfs supports a new, more powerful and extensible, descriptor format. Since ffs-test is probably the first thing users of the functionfs interface see when they start writing functionfs user space daemons, convert it to use the new format thus promoting it.

2014-06-30tools: ffs-test: fix header values endianessMichal Nazarewicz
It appears that no one ever run ffs-test on a big-endian machine, since it used cpu-endianess for fs_count and hs_count fields which should be in little-endian format. Fix by wrapping the numbers in cpu_to_le32. Cc: stable@vger.kernel.org Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-06-19tools: ffs-test: convert to new descriptor format fixing compilation errorMichal Nazarewicz
Commit [ac8dde11: “usb: gadget: f_fs: Add flags to descriptors block”] which introduced a new descriptor format for FunctionFS removed the usb_functionfs_descs_head structure, which is still used by ffs-test. tool. Convert ffs-test by converting it to use the new header format. For testing kernels prior to 3.14 (when the new format was introduced) and parsing of the legacy headers in the new kernels, provide a compilation flag to make the tool use the old format. Finally, include information as to when the legacy FunctionFS headers format has been deprecated (which is also when the new one has been introduced).

2012-05-07USB: ffs-test: fix length argument of out function callMatthias Fend
The out functions should only handle actual available data instead of the complete buffer. Otherwise for example the ep0_consume function will report ghost events since it tries to decode the complete buffer - which may contain partly invalid data.
