由 Ard Biesheuvel 提交于
The newly added code that emits ksymtab entries as pairs of 32-bit relative references interacts poorly with the way powerpc lays out its address space: when a module exports a per-CPU variable, the primary module region covering the ksymtab entry -and thus the 32-bit relative reference- is too far away from the actual per-CPU variable's base address (to which the per-CPU offsets are applied to obtain the respective address of each CPU's copy), resulting in corruption when the module loader attempts to resolve symbol references of modules that are loaded on top and link to the exported per-CPU symbol. So let's disable this feature on powerpc. Even though it implements CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so KASLR kernels (which are the main target of the feature) do not exist on powerpc anyway.

100 ms is not enough time for the LSPCON adapter on Intel NUC devices to settle. This causes dropped display modes at boot or screen reconfiguration. Empirical testing can reproduce the error up to a timeout of 190 ms. Basic boot and stress testing at 200 ms has not (yet) failed. Increase timeout to 400 ms to get some margin of error.

When a targetport is removed from the config, fcloop will avoid calling the LS done() routine thinking the targetport is gone. This leaves the initiator reset/reconnect hanging as it waits for a status on the Create_Association LS for the reconnect. Change the filter in the LS callback path. If tport null (set when failed validation before "sending to remote port"), be sure to call done. This was the main bug. But, continue the logic that only calls done if tport was set but there is no remoteport (e.g. case where remoteport has been removed, thus host doesn't expect a completion).

In many architectures loads may be reordered with older stores to different locations. In the nvme driver the following two operations could be reordered: - Write shadow doorbell (dbbuf_db) into memory. - Read EventIdx (dbbuf_ei) from memory. This can result in a potential race condition between driver and VM host processing requests (if given virtual NVMe controller has a support for shadow doorbell). If that occurs, then the NVMe controller may decide to wait for MMIO doorbell from guest operating system, and guest driver may decide not to issue MMIO doorbell on any of subsequent commands. This issue is purely timing-dependent one, so there is no easy way to reproduce it. Currently the easiest known approach is to run "Oracle IO Numbers" (orion) that is shipped with Oracle DB: orion -run advanced -num_large 0 -size_small 8 -type rand -simulate \ concat -write 40 -duration 120 -matrix row -testname nvme_test Where nvme_test is a .lun file that contains a list of NVMe block devices to run test against. Limiting number of vCPUs assigned to given VM instance seems to increase chances for this bug to occur. On test environment with VM that got 4 NVMe drives and 1 vCPU assigned the virtual NVMe controller hang could be observed within 10-20 minutes. That correspond to about 400-500k IO operations processed (or about 100GB of IO read/writes). Orion tool was used as a validation and set to run in a loop for 36 hours (equivalent of pushing 550M IO operations). No issues were observed. That suggest that the patch fixes the issue.
