usb-gadget-ether: prevent oops caused by error interrupt race

2007-11-16T17:30:22Z

patch 5395353e0c8272fe73ac914acd7e4add0da2bef0 in mainline. Fix a longstanding race in the Ethernet gadget driver, which can cause an oops on device disconnect. The fix is just to make the TX path check whether its freelist is empty. That check is otherwise not necessary, since the queue is always stopped when that list empties (and restarted when request completion puts an entry back on that freelist). The race window starts when the network code decides to transmit a packet, and ends when hard_start_xmit() grabs the freelist lock. When disconnect() is called inside that window, it shuts down the TX queue and breaks the otherwise-solid assumption that packets are never sent through a TX queue that's stopped.

USB: fix serial gadget ACM breakage

2007-09-11T14:48:16Z

Two of the CDC ACM control requests in the serial gadget have never been correct, and have been reported to cause serious troubles ... as in, soft lockup and maybe watchdog reset (depending on hardware). This patch makes those request fail cleanly, rather than misbehaving. Someone using CDC ACM should fix them according to the FIXME comments which now replace the previous bugs.

USB: fsl_usb2_udc: fix bug in processing setup requests

2007-08-22T21:28:00Z

Kim Liu found that in the original code certain class setup requests are wrongly recognized and processed as standard setup requests. For that reason gadget ether can't work in RNDIS mode with Windows host. The patch fixes the setup request processing code, and makes class requests correctly passed to gadget layer.

USB: g_file_storage: fix bug in DMA buffer handling

2007-08-22T21:27:59Z

This patch (as963) fixes a recently-introduced bug. The gadget conversion removing DMA-mapped buffer allocation did not remove quite enough code from the g_file_storage driver; DMA pointers were being set to 0. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: remove DEBUG definition from dummy_hcd

2007-08-22T21:27:47Z

This patch (as958) removes an unneeded and unwanted #define line from dummy_hcd. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: Stall control endpoint when file storage class request wValue != 0

2007-08-22T21:27:44Z

This patch makes the File Storage Gadget stall the control endpoint when a MSC class request is made with wValue != 0. This change makes some MSC compliance test warnings disappear. Signed-off-by: Luis Lloret Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: px2xx_udc bugfix, missing check for gpio_pullup

2007-08-22T21:27:43Z

git commit b2bbb20b37d734443d1c279d0033a64f6095db54 added direct support for PXA GPIO D+ pullup as alternative to the older udc_command ops method. This was done by introduction of the pxa2xx_udc_mach_info member "gpio_pullup" which, if initialized, is now used in (almost) all places where udc_command used to be called. This patch fixes two places where checks for availability of D+ pullup control still only honor udc_command. Signed-off-by: Uli Luckas Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: "sparse" cleanups for usb gadgets

2007-07-30T20:27:47Z

This removes complaints about the gadget stack which are generated by the currrent "sparse": it doesn't like the fact that zero is the null pointer. (Last I checked, C guarantees that's correct ...) Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: more pxa2xx_udc dead code removal

2007-07-30T20:27:47Z

Remove some more dead code from the pxa2xx_udc driver: support for a no-longer-undocumented hardware "test mode". Newer chips made this the default, evidently as the best workaround for deep silicon bugs. The interest was that this seemed to be the only way to kick in the (documented!) double buffering capability. Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: m66592-udc: fixes some problems

2007-07-20T00:46:05Z

This patch incorporates some updates from the review of the Renesas m66592-udc driver. Updates include: - Fix some locking bugs; and add a few sparse annotations - Don't #define __iomem ! - Lots of whitespace fixes (most of the patch by volume) - Some #include file trimmage - Other checkpatch.pl and sparse updates - Alphabetized and slightly-more-informative Kconfig - Don't use the ID which was assigned to the amd5536udc driver. - Remove pointless suspend/resume methods updating obsolete field. - Some section fixups - Fix some leak bugs - Fix byteswapping Signed-off-by: David Brownell Signed-off-by: Yoshihiro Shimoda Signed-off-by: Greg Kroah-Hartman
