Takashi Iwai authored
The latest fix for the non-contiguous memalloc helper changed the allocation method for a non-IOMMU system to use only the fallback allocator. This should have worked, but it caused a problem sometimes when too many non-contiguous pages are allocated that can't be treated by HD-audio controller. As a quirk workaround, go back to the original strategy: use dma_alloc_noncontiguous() at first, and apply the fallback only when it fails, but only for non-IOMMU case. We'll need a better fix in the fallback code as well, but this workaround should paper over most cases. Fixes: 9736a325 ("ALSA: memalloc: Don't fall back for SG-buffer with IOMMU") Reported-by:

While the ATA specification states that a device should return command aborted for all commands queued after the device has entered error state, since ATA only keeps the sense data for the latest command (in non-NCQ case), we really don't want to send block layer commands to the device after it has entered error state. (Only ATA EH commands should be sent, to read the sense data etc.) Currently, scsi_queue_rq() will check if scsi_host_in_recovery() (state is SHOST_RECOVERY), and if so, it will _not_ issue a command via: scsi_dispatch_cmd() -> host->hostt->queuecommand() (ata_scsi_queuecmd()) -> __ata_scsi_queuecmd() -> ata_scsi_translate() -> ata_qc_issue() Before commit e494f6a7 ("[SCSI] improved eh timeout handler"), when receiving a TFES error IRQ, the call chain looked like this: ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort() -> ata_qc_complete() -> ata_qc_schedule_eh() -> blk_abort_request() -> blk_rq_timed_out() -> q->rq_timed_out_fn() (scsi_times_out()) -> scsi_eh_scmd_add() -> scsi_host_set_state(shost, SHOST_RECOVERY) Which meant that as soon as an error IRQ was serviced, SHOST_RECOVERY would be set. However, after commit e494f6a7 ("[SCSI] improved eh timeout handler"), scsi_times_out() will instead call scsi_abort_command() which will queue delayed work, and the worker function scmd_eh_abort_handler() will call scsi_eh_scmd_add(), which calls scsi_host_set_state(shost, SHOST_RECOVERY). So now, after the TFES error IRQ has been serviced, we need to wait for the SCSI workqueue to run its work before SHOST_RECOVERY gets set. It is worth noting that, even before commit e494f6a7 ("[SCSI] improved eh timeout handler"), we could receive an error IRQ from the time when scsi_queue_rq() checks scsi_host_in_recovery(), to the time when ata_scsi_queuecmd() is actually called. In order to handle both the delayed setting of SHOST_RECOVERY and the window where we can receive an error IRQ, add a check against ATA_PFLAG_EH_PENDING (which gets set when servicing the error IRQ), inside ata_scsi_queuecmd() itself, while holding the ap->lock. (Since the ap->lock is held while servicing IRQs.) Fixes: e494f6a7 ("[SCSI] improved eh timeout handler") Signed-off-by:

Pull kvm "This is a pretty large diffstat for this time of the release. The main culprit is a reorganization of the AMD assembly trampoline, allowing percpu variables to be accessed early. This is needed for the return stack depth tracking retbleed mitigation that will be in 6.2, but it also makes it possible to tighten the IBRS restore on vmexit. The latter change is a long tail of the spectrev2/retbleed patches (the corresponding Intel change was simpler and went in already last June), which is why I am including it right now instead of sharing a topic branch with tip. Being assembly and being rich in comments makes the line count balloon a bit, but I am pretty confident in the change (famous last words) because the reorganization actually makes everything simpler and more understandable than before. It has also had external review and has been tested on the aforementioned 6.2 changes, which explode quite brutally without the fix.

io_poll_double_prepare() | io_poll_wake() | poll->head = NULL smp_load(&poll->head); /* NULL */ | flags = req->flags; | | req->flags &= ~SINGLE_POLL; req->flags = flags | DOUBLE_POLL | The idea behind io_poll_double_prepare() is to serialise with the first poll entry by taking the wq lock. However, it's not safe to assume that io_poll_wake() is not running when we can't grab the lock and so we may race modifying req->flags. Skip double poll setup if that happens. It's ok because the first poll entry will only be removed when it's definitely completing, e.g. pollfree or oneshot with a valid mask.

get_port_from_cmdline() returns an int, yet is assigned to a char, which is wrong in its own right, but also, with char becoming unsigned, this poses problems, because -1 is used as an error value. Further complicating things, fw_init_early_console() is only ever called with a -1 argument. Fix this up by removing the unused argument from fw_init_early_console() and treating port as a proper signed integer. Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by:

When zapping a GFN range, pass 0 => ALL_ONES for the to-be-invalidated range to effectively block all page faults while the zap is in-progress. The invalidation helpers take a host virtual address, whereas zapping a GFN obviously provides a guest physical address and with the wrong unit of measurement (frame vs. byte). Alternatively, KVM could walk all memslots to get the associated HVAs, but thanks to SMM, that would require multiple lookups. And practically speaking, kvm_zap_gfn_range() usage is quite rare and not a hot path, e.g. MTRR and CR0.CD are almost guaranteed to be done only on vCPU0 during boot, and APICv inhibits are similarly infrequent operations.

In the error path in ata_tport_add(), when calling put_device(), ata_tport_release() is called, it will put the refcount of 'ap->host'. And then ata_host_put() is called again, the refcount is decreased to 0, ata_host_release() is called, all ports are freed and set to null. When unbinding the device after failure, ata_host_stop() is called to release the resources, it leads a null-ptr-deref(), because all the ports all freed and null.
