2021-06-02nvme-loop: reset queue count to 1 in nvme_loop_destroy_io_queues()Hannes Reinecke1-0/+1
The queue count is increased in nvme_loop_init_io_queues(), so we need to reset it to 1 at the end of nvme_loop_destroy_io_queues(). Otherwise the function is not re-entrant safe, and crash will happen during concurrent reset and remove calls.

2021-06-01virtio_net: get build_skb() buf by data ptrXuan Zhuo1-11/+6
In the case of merge, the page passed into page_to_skb() may be a head page, not the page where the current data is located. So when trying to get the buf where the data is located, we should get buf based on headroom instead of offset. This patch solves this problem. But if you don't use this patch, the original code can also run, because if the page is not the page of the current data, the calculated tailroom will be less than 0, and will not enter the logic of build_skb() . The significance of this patch is to modify this logical problem, allowing more situations to use build_skb().

2021-06-01spi: Cleanup on failure of initial setupLukas Wunner5-19/+54
Commit c7299fea6769 ("spi: Fix spi device unregister flow") changed the SPI core's behavior if the ->setup() hook returns an error upon adding an spi_device: Before, the ->cleanup() hook was invoked to free any allocations that were made by ->setup(). With the commit, that's no longer the case, so the ->setup() hook is expected to free the allocations itself. I've identified 5 drivers which depend on the old behavior and am fixing them up hereinafter: spi-bitbang.c spi-fsl-spi.c spi-omap-uwire.c spi-omap2-mcspi.c spi-pxa2xx.c Importantly, ->setup() is not only invoked on spi_device *addition*: It may subsequently be called to *change* SPI parameters. If changing these SPI parameters fails, freeing memory allocations would be wrong. That should only be done if the spi_device is finally destroyed. I am therefore using a bool "initial_setup" in 4 of the affected drivers to differentiate between the invocation on *adding* the spi_device and any subsequent invocations: spi-bitbang.c spi-fsl-spi.c spi-omap-uwire.c spi-omap2-mcspi.c In spi-pxa2xx.c, it seems the ->setup() hook can only fail on spi_device addition, not any subsequent calls. It therefore doesn't need the bool. It's worth noting that 5 other drivers already perform a cleanup if the ->setup() hook fails. Before c7299fea6769, they caused a double-free if ->setup() failed on spi_device addition. Since the commit, they're fine. These drivers are: spi-mpc512x-psc.c spi-pl022.c spi-s3c64xx.c spi-st-ssc4.c spi-tegra114.c (spi-pxa2xx.c also already performs a cleanup, but only in one of several error paths.)

2021-05-31scsi: lpfc: Fix failure to transmit ABTS on FC linkJames Smart1-3/+1
The abort_cmd_ia flag in an abort wqe describes whether an ABTS basic link service should be transmitted on the FC link or not. Code added in lpfc_sli4_issue_abort_iotag() set the abort_cmd_ia flag incorrectly, surpressing ABTS transmission. A previous LPFC change to build an abort wqe inverted prior logic that determined whether an ABTS was to be issued on the FC link. Revert this logic to its proper state.

2021-05-31x86/thermal: Fix LVT thermal setup for SMI delivery modeBorislav Petkov1-4/+11
There are machines out there with added value crap^WBIOS which provide an SMI handler for the local APIC thermal sensor interrupt. Out of reset, the BSP on those machines has something like 0x200 in that APIC register (timestamps left in because this whole issue is timing sensitive): [ 0.033858] read lvtthmr: 0x330, val: 0x200 which means: - bit 16 - the interrupt mask bit is clear and thus that interrupt is enabled - bits [10:8] have 010b which means SMI delivery mode. Now, later during boot, when the kernel programs the local APIC, it soft-disables it temporarily through the spurious vector register: setup_local_APIC: ... /* * If this comes from kexec/kcrash the APIC might be enabled in * SPIV. Soft disable it before doing further initialization. */ value = apic_read(APIC_SPIV); value &= ~APIC_SPIV_APIC_ENABLED; apic_write(APIC_SPIV, value); which means (from the SDM): "10.4.7.2 Local APIC State After It Has Been Software Disabled ... * The mask bits for all the LVT entries are set. Attempts to reset these bits will be ignored." And this happens too: [ 0.124111] APIC: Switch to symmetric I/O mode setup [ 0.124117] lvtthmr 0x200 before write 0xf to APIC 0xf0 [ 0.124118] lvtthmr 0x10200 after write 0xf to APIC 0xf0 This results in CPU 0 soft lockups depending on the placement in time when the APIC soft-disable happens. Those soft lockups are not 100% reproducible and the reason for that can only be speculated as no one tells you what SMM does. Likely, it confuses the SMM code that the APIC is disabled and the thermal interrupt doesn't doesn't fire at all, leading to CPU 0 stuck in SMM forever... Now, before 4f432e8bb15b ("x86/mce: Get rid of mcheck_intel_therm_init()") due to how the APIC_LVTTHMR was read before APIC initialization in mcheck_intel_therm_init(), it would read the value with the mask bit 16 clear and then intel_init_thermal() would replicate it onto the APs and all would be peachy - the thermal interrupt would remain enabled. But that commit moved that reading to a later moment in intel_init_thermal(), resulting in reading APIC_LVTTHMR on the BSP too late and with its interrupt mask bit set. Thus, revert back to the old behavior of reading the thermal LVT register before the APIC gets initialized.
