USB: dummy-hcd: Fix uninitialized array use in init()

2020-12-21T12:28:19Z

commit e90cfa813da7a527785033a0b247594c2de93dd8 upstream. This error path err_add_pdata: for (i = 0; i < mod_data.num; i++) kfree(dum[i]); can be triggered when not all dum's elements are initialized. Fix this by initializing all dum's elements to NULL.

usb: gadget: goku_udc: fix potential crashes in probe

2020-11-18T18:22:09Z

[ Upstream commit 0d66e04875c5aae876cf3d4f4be7978fa2b00523 ] goku_probe() goes to error label "err" and invokes goku_remove() in case of failures of pci_enable_device(), pci_resource_start() and ioremap(). goku_remove() gets a device from pci_get_drvdata(pdev) and works with it without any checks, in particular it dereferences a corresponding pointer. But goku_probe() did not set this device yet. So, one can expect various crashes. The patch moves setting the device just after allocation of memory for it.

Pull tasklets API update from Kees Cook: "These are the infrastructure updates needed to support converting the tasklet API to something more modern (and hopefully for removal further down the road). There is a 300-patch series waiting in the wings to get set out to subsystem maintainers, but these changes need to be present in the kernel first. Since this has some treewide changes, I carried this series for -next instead of paining Thomas with it in -tip, but it's got his Ack. This is similar to the timer_struct modernization from a while back, but not nearly as messy (I hope). :) - Prepare for tasklet API modernization (Romain Perier, Allen Pais, Kees Cook)" * tag 'tasklets-v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: tasklet: Introduce new initialization API treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD() usb: gadget: udc: Avoid tasklet passing a global

treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()

2020-07-30T18:15:58Z

This converts all the existing DECLARE_TASKLET() (and ...DISABLED) macros with DECLARE_TASKLET_OLD() in preparation for refactoring the tasklet callback type. All existing DECLARE_TASKLET() users had a "0" data argument, it has been removed here as well. Reviewed-by: Greg Kroah-Hartman Acked-by: Thomas Gleixner Signed-off-by: Kees Cook

There's no reason for the tasklet callback to set an argument since it always uses a global. Instead, use the global directly, in preparation for converting the tasklet subsystem to modern callback conventions. Reviewed-by: Greg Kroah-Hartman Acked-by: Thomas Gleixner Signed-off-by: Kees Cook
