[PATCH 1/2] fs: dlm: fix sock release if listen fails

by Alexander Aring

This patch fixes a double sock_release() call when the listen() is called for the dlm lowcomms listen socket. The caller of dlm_listen_for_all should never care about releasing the socket if dlm_listen_for_all() fails, it's done now only once if listen() fails.

It'd great if we can see the driver log. > To interject, what should happen in dwc3_gadget_ep_reclaim_completed_trb if the IOC bit is not set (but the IMI bit is) and -EXDEV status is passed into it? If the function returns 0, another attempt to reclaim may occur. If this happens and the next request did have the HWO bit set, the function would return 1 but dwc3_gadget_ep_cleanup_completed_request would still call dwc3_gadget_giveback. As a test (without this patch), I added a check to see if HWO bit was set in dwc3_gadget_ep_cleanup_completed_requests(). If the usecase was ISOC and the HWO bit was set I avoided calling dwc3_gadget_ep_cleanup_completed_request(). This seemed to also avoid the iommu related crash being seen. Is there an issue in this area that needs to be corrected instead? Not having interrupts set for each request may be causing some new issues to be uncovered. As far as the crash seen without this patch, no good stacktrace is given. Line provided for crash varied a bit, but tended to appear towards the end of dwc3_stop_active_transfer() or dwc3_gadget_endpoint_trbs_complete(). Since dwc3_gadget_endpoint_trbs_complete() can be called from multiple locations, I duplicated the function to help identify which path it was likely being called from. At the time of the crashes seen, dwc3_gadget_endpoint_transfer_in_progress() appeared to be the caller. dwc3_gadget_endpoint_transfer_in_progress() ->dwc3_gadget_endpoint_trbs_complete() (crashed towards end of here) ->dwc3_stop_active_transfer() (sometimes crashed towards end of here) I hope this clarifies things a bit. > > > > > > > > The dwc3 driver would only give back the requests if the TRBs of the > > > associated requests are completed or when the device is disconnected. > > > If the TRB indicated missed isoc, that means that the TRB is completed > > > and its status was updated. > > > > Interesting, the device is not disconnected as we don't get the > > -ESHUTDOWN status back and with this patch in place things continue > > after a -EXDEV status is received. > > > > Actually, minor correction here: a recent change > b44c0e7fef51 ("usb: dwc3: gadget: conditionally remove requests") > changed -ESHUTDOWN request status to -ECONNRESET when disable endpoint. > This doesn't look right. > > While disabling endpoint may also apply for other cases such as > switching alternate interface in addition to disconnect, -ESHUTDOWN > seems more fitting there. > btw, we don't have "usb: dwc3: gadget: conditionally remove requests" in our baseline > Hi Michael, > > Can you help clarify for the change above?

[PATCH] ACPI: NUMA: Add CXL CFMWS 'nodes' to the possible nodes set

by Dan Williams

The ACPI CEDT.CFMWS indicates a range of possible address where new CXL regions can appear. Each range is associated with a QTG id (QoS Throttling Group id). For each range + QTG pair that is not covered by a proximity domain in the SRAT, Linux creates a new NUMA node. However, the commit that added the new ranges missed updating the node_possible mask which causes memory_group_register() to fail. Add the new nodes to the nodes_possible mask.

[PATCH v2 2/2] minstrel_ht: Mitigate minstrel_ht_get_expected_throughput() for BTI

by Pawan Gupta

Static analysis tools indicate that indirect target minstrel_ht_get_expected_throughput() could be used as a disclosure gadget for Intra-mode Branch Target Injection (IMBTI) or Branch History Injection (BHI). ASM generated by compilers indicate a construct of a typical disclosure gadget, where function arguments can be used to speculatively access and transmit the contents of an arbitrary memory location. Mitigate it by adding a speculation barrier. Reported-by: Scott D.

[PATCH v2 1/2] nospec: Add a generic barrier_nospec()

by Pawan Gupta

barrier_nospec() is a speculation barrier with arch dependent implementation. To be able to use barrier_nospec() in non-architecture code add a generic version that does nothing. Architectures that don't have a use case for speculation barrier shouldn't need to define an arch specific version. Architectures needing speculation barrier can override the generic version in their asm/barrier.h.
