Currently psw_idle does not allocate a stack frame and does not save its r14 and r15 into the save area. Even though this is valid from call ABI point of view, because psw_idle does not make any calls explicitly, in reality psw_idle is an entry point for controlled transition into serving interrupts. So, in practice, psw_idle stack frame is analyzed during stack unwinding. Depending on build options that r14 slot in the save area of psw_idle might either contain a value saved by previous sibling call or complete garbage.

Currently when interrupt arrives to cpu while in kernel context INT_HANDLER macro (used for ext_int_handler and io_int_handler) allocates new stack frame and pt_regs on the kernel stack and sets up the backchain to jump over the pt_regs to the frame which has been interrupted. This is not ideal to two reasons: 1. This hides the fact that kernel stack contains interrupt frame in it and hence breaks arch_stack_walk_reliable(), which needs to know that to guarantee "reliability" and checks that there are no pt_regs on the way. 2. It breaks the backchain unwinder logic, which assumes that the next stack frame after an interrupt frame is reliable, while it is not. In some cases (when r14 contains garbage) this leads to early unwinding termination with an error, instead of marking frame as unreliable and continuing. To address that, only set backchain to 0.

This patch fixes a lockdep splat introduced by commit f21916ec ("s390/vfio-ap: clean up vfio_ap resources when KVM pointer invalidated"). The lockdep splat only occurs when starting a Secure Execution guest. Crypto virtualization (vfio_ap) is not yet supported for SE guests; however, in order to avoid this problem when support becomes available, this fix is being provided. The circular locking dependency was introduced when the setting of the masks in the guest's APCB was executed while holding the matrix_dev->lock. While the lock is definitely needed to protect the setting/unsetting of the matrix_mdev->kvm pointer, it is not necessarily critical for setting the masks; so, the matrix_dev->lock will be released while the masks are being set or cleared. Keep in mind, however, that another process that takes the matrix_dev->lock can get control while the masks in the guest's APCB are being set or cleared as a result of the driver being notified that the KVM pointer has been set or unset. This could result in invalid access to the matrix_mdev->kvm pointer by the intervening process. To avoid this scenario, two new fields are being added to the ap_matrix_mdev struct: struct ap_matrix_mdev { ... bool kvm_busy; wait_queue_head_t wait_for_kvm; ... }; The functions that handle notification that the KVM pointer value has been set or cleared will set the kvm_busy flag to true until they are done processing at which time they will set it to false and wake up the tasks on the matrix_mdev->wait_for_kvm wait queue. Functions that require access to matrix_mdev->kvm will sleep on the wait queue until they are awakened at which time they can safely access the matrix_mdev->kvm field.

On s390 each PCI device has a user-defined ID (UID) exposed under /sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI device's primary index and to match the device within Linux to the device configured in the hypervisor. To serve as a primary identifier the UID must be unique within the Linux instance, this is guaranteed by the platform if and only if the UID Uniqueness Checking flag is set within the CLP List PCI Functions response. While the UID has been exposed to userspace since commit ac4995b9 ("s390/pci: add some new arch specific pci attributes") whether or not the platform guarantees its uniqueness for the lifetime of the Linux instance while defined is not visible from userspace. Remedy this by exposing this as a per device attribute at /sys/bus/pci/devices/<dev>/uid_is_unique Keeping this a per device attribute allows for maximum flexibility if we ever end up with some devices not having a UID or not enjoying the guaranteed uniqueness.

In commit dee60c0d ("s390/pci: add zpci_event_hard_deconfigured()") we added a zdev_enabled() check to what was previously an uncoditional call to zpci_disable_device(). There are two problems with that. Firstly zpci_had_deconfigured() is only called on event 0x0304 for which the device is always already disabled by the platform so it is always false. Secondly zpci_disable_device() not only disables the device but also calls zpci_dma_exit_device() which is thus not called and we leak the DMA tables. Fix this by calling zpci_disable_device() unconditionally to perform Linux side cleanup including the freeing of DMA tables.

Li Wang reported that clock_gettime(CLOCK_MONOTONIC_RAW, ...) returns incorrect values when time is provided via vdso instead of system call: vdso_ts_nsec = 4484351380985507, vdso_ts.tv_sec = 4484351, vdso_ts.tv_nsec = 380985507 sys_ts_nsec = 1446923235377, sys_ts.tv_sec = 1446, sys_ts.tv_nsec = 923235377 Within the s390 specific vdso function __arch_get_hw_counter() reads tod clock steering values from the arch_data member of the passed in vdso_data structure. Problem is that only for the CS_HRES_COARSE vdso_data arch_data is initialized and gets updated. The CS_RAW specific vdso_data does not contain any valid tod_clock_steering information, which explains the different values. Fix this by initializing and updating all vdso_datas. Reported-by:

The s390 specific vdso function __arch_get_hw_counter() is supposed to consider tod clock steering. If a tod clock steering event happens and the tod clock is set to a new value __arch_get_hw_counter() will not return the real tod clock value but slowly drift it from the old delta until the returned value finally matches the real tod clock value again. Unfortunately the type of tod_steering_delta unsigned while it is supposed to be signed. It depends on if tod_steering_delta is negative or positive in which direction the vdso code drifts the clock value. Worst case is now that instead of drifting the clock slowly it will jump into the opposite direction by a factor of two. Fix this by simply making tod_steering_delta signed.

We are spending way too much effort on qdio-internal bookkeeping for QAOB management & caching, and it's still not robust. Once qdio's TX path has detached the QAOB from a PENDING buffer, we lost all track of it until it shows up in a CQ notification again. So if the device is torn down before that notification arrives, we leak the QAOB. Just have the driver take care of it, and simply pass down a QAOB if they want a TX with async-completion capability. For a buffer in PENDING state that requires the QAOB for final completion, qeth can now also try to recycle the buffer's QAOB rather than unconditionally freeing it. This also eliminates the qdio_outbuf_state array, which was only needed to transfer the aob->user1 tag from the driver to the qdio layer. Signed-off-by:

This patch introduces the mechanism to inject artificial events to the CIO layer. One of the main-event type which triggers the CommonIO operations are Channel Report events. When a malfunction or other condition affecting channel-subsystem operation is recognized, a Channel Report Word (consisting of one or more CRWs) describing the condition is made pending for retrieval and analysis by the program. The CRW contains information concerning the identity and state of a facility following the detection of the malfunction or other condition. The patch introduces two debugfs interfaces which can be used to inject 'artificial' events from the userspace. It is intended to provide an easy means to increase the test coverage for CIO code. And this functionality can be enabled via a new configuration option CONFIG_CIO_INJECT. The newly introduces debugfs interfaces can be used as mentioned below to generate different fake-events. To use the crw_inject, first we should enable it by using enable_inject interface. i.e echo 1 > /sys/kernel/debug/s390/cio/enable_inject After the first step, user can simulate CRW as follows: echo <solicited> <overflow> <chaining> <rsc> <ancillary> <erc> <rsid> \ > /sys/kernel/debug/s390/cio/crw_inject Example: A permanent error ERC on CHPID 0x60 would look like this: echo 0 0 0 4 0 6 0x60 > /sys/kernel/debug/s390/cio/crw_inject and an initialized ERC on the same CHPID: echo 0 0 0 4 0 2 0x60 > /sys/kernel/debug/s390/cio/crw_inject Signed-off-by: -

The current zdev->state mixes the configuration states supported by CLP with an additional Online state which is used inconsistently to include enabled zPCI functions which are not yet visible to the common PCI subsytem. In preparation for a clean separation between architected configuration states and fine grained function states remove the Online function state. Where we previously checked for Online it is more accurate to check if the function is enabled to avoid an edge case where a disabled device was still treated as Online. This also simplifies checks whether a function is configured as this is now directly reflected by its function state. Reviewed-by:

Kernel and console/TTY messages written to the SCLP line mode console are wrapped at 80 characters per line by the associated SCLP driver. This makes long lines of output difficult to read, and requires editing of wrapped lines copied from the output device. Neither the firmware interface used to access the SCLP console, nor the HMC "Operating System Messages" web interface that displays these messages require such a length limit. Also other operating systems such as z/VM do not impose similar limits on messages they emit to the same console device. This patch therefore increases the limit to 320 characters per line to make SCLP line mode console output more readable. As a result 99% of lines written during a typical boot will not be wrapped, compared to about 50% wrapped lines at 80 characters per line. Another positive side-effect of this change is that the HMC console interface is able to keep more messages in its history buffer due to fewer line-breaks being generated. In a worst case scenario this means that a 4k console buffer is emitted with the last ~400 bytes empty (320 text + 78 headers). This is more than offset by the fact that each line that is not truncated saves 78 header bytes in the buffer. As a result the actual number of emitted buffers should be about the same as with the 80 character limit. This patch also removes the differentiation between line lengths of SCLP line mode output on z/VM and non-z/VM systems. While the z/VM hypervisor adds a prefix in front of each line ('xx: ' where xx is the number of the CPU issuing the message), adjusting Linux line lengths did not significantly increase readability of console output, and makes even less of a difference with longer lines.
