Create a list to store command structures, add a structure to it every time a command is submitted, and remove it from the list once we get a command completion event matching the command. Callers that wait for completion will free their command structures themselves. The other command structures are freed in the command completion event handler. Also add a check that prevents queuing commands if host is dying Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Mathias Nyman authored
To create a global command queue we require that each command put on the command ring is submitted with a command structure. Functions that queue commands and wait for completion need to allocate a command before submitting it, and free it once completed. The following command queuing functions need to be modified. xhci_configure_endpoint() xhci_address_device() xhci_queue_slot_control() xhci_queue_stop_endpoint() xhci_queue_new_dequeue_state() xhci_queue_reset_ep() xhci_configure_endpoint() xhci_configure_endpoint() could already be called with a command structure, and only xhci_check_maxpacket and xhci_check_bandwidth did not do so. These are changed and a command structure is now required. This change also simplifies the configure endpoint command completion handling and the "goto bandwidth_change" handling code can be removed. In some cases the command queuing function is called in interrupt context. These commands needs to be allocated atomically, and they can't wait for completion. These commands will in this patch be freed directly after queuing, but freeing will be moved to the command completion event handler in a later patch once we get the global command queue up.(Just so that we won't leak memory in the middle of the patch set) Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

xHCI host controllers may only support a limited number of device slot IDs, which is usually far less than the theoretical maximum number of devices (255) that the USB specifications advertise. This is frustrating to consumers that expect to be able to plug in a large number of devices. Add a print statement when the Enable Slot command fails to show how many devices the host supports. We can't change hardware manufacturer's design decisions, but hopefully we can save customers a little bit of time trying to debug why their host mysteriously fails when too many devices are plugged in.

All other phy drivers use 'select', while this one is the only one to use 'depends on'. This is not a bug, just slightly inconsistent, so let's change it to do things the same way as everyone else. We may also want to turn GENERIC_PHY into a silent option that only ever gets turned on if another driver needs it.

Pull x86 fixes from Peter Anvin: "A somewhat unpleasantly large collection of small fixes. The big ones are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'. It was using __init functions with predictably suboptimal results. Another key fix is a build fix which would produce output that simply would not decompress correctly in some configuration, due to the existing Makefiles picking up an unfortunate local label and mistaking it for the global symbol _end. Additional fixes include the handling of 64-bit numbers when setting the vdso data page (a latent bug which became manifest when i386 started exporting a vdso with time functions), a fix to the new MSR manipulation accessors which would cause features to not get properly unblocked, a build fix for 32-bit userland, and a few new platform quirks" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall() x86: Fix typo in MSR_IA32_MISC_ENABLE_LIMIT_CPUID macro x86: Fix typo preventing msr_set/clear_bit from having an effect x86/intel: Add quirk to disable HPET for the Baytrail platform x86/hpet: Make boot_hpet_disable extern x86-64, build: Fix stack protector Makefile breakage with 32-bit userland x86/reboot: Add reboot quirk for Certec BPC600 asmlinkage: Add explicit __visible to drivers/*, lib/*, kernel/* asmlinkage, x86: Add explicit __visible to arch/x86/* asmlinkage: Revert "lto: Make asmlinkage __visible" x86, build: Don't get confused by local symbols x86/efi: earlyprintk=efi,keep fix

With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall() may lose upper bits or, worse, add them since compiler will do this: (u64)(tk->wall_to_monotonic.tv_nsec << tk->shift) instead of ((u64)tk->wall_to_monotonic.tv_nsec << tk->shift) So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in the subsequent 'while' loop. We need an explicit cast.

The second fix is to a bug that was introduced in this merge window that allowed for a tracepoint funcs pointer to be used after it was freed.

Commit de7b2973 "tracepoint: Use struct pointer instead of name hash for reg/unreg tracepoints" introduces a use after free by calling release_probes on the old struct tracepoint array before the newly allocated array is published with rcu_assign_pointer. There is a race window where tracepoints (RCU readers) can perform a "use-after-grace-period-after-free", which shows up as a GPF in stress-tests.

The replacement of the 'count' variable by two variables 'incs' and 'decs' to resolve some race conditions during module unloading was done in parallel with some cleanup in the trace subsystem, and was integrated as a merge. Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.

This reverts commit c42deffd. commit <mmc: rtsx: add support for pre_req and post_req> did use mutex_unlock() in tasklet, but mutex_unlock() can't be used in tasklet(atomic context). The driver needs to use mutex to avoid concurrency, so we can't use tasklet here, the patch need to be removed. The spinlock host->lock and pcr->lock may deadlock, one way to solve the deadlock is remove host->lock in sd_isr_done_transfer(), but if using workqueue the we can avoid using the spinlock and also avoid the problem.

If you are using a 64-bit kernel with 32-bit userland, then scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc with -mcmodel=kernel, which produces: <stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode and trips the "broken compiler" test at arch/x86/Makefile:120. There are several places a fix is possible, but the following seems cleanest. (But it's minimal; it would also be possible to factor out a bunch of stuff from the two branches of the if.)
