CVS commit: src/sys/uvm
Module Name:src Committed By: chs Date: Sun Aug 13 23:06:07 UTC 2023 Modified Files: src/sys/uvm: uvm_fault.c Log Message: uvm: prevent TLB invalidation races during COW resolution When a thread takes a page fault which results in COW resolution, other threads in the same process can be concurrently accessing that same mapping on other CPUs. When the faulting thread updates the pmap entry at the end of COW processing, the resulting TLB invalidations to other CPUs are not done atomically, so another thread can write to the new writable page and then a third thread might still read from the old read-only page, resulting in inconsistent views of the page by the latter two threads. Fix this by removing the pmap entry entirely for the original page before we install the new pmap entry for the new page, so that the new page can only be modified after the old page is no longer accessible. This fixes PR 56535 as well as the netbsd versions of problems described in various bug trackers: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225584 https://reviews.freebsd.org/D14347 https://github.com/golang/go/issues/34988 To generate a diff of this commit: cvs rdiff -u -r1.233 -r1.234 src/sys/uvm/uvm_fault.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.

Couple reasons: 1. I never adequately tested it. I started X a few years ago (and a couple drm updates ago) but that's it. (Also only on 32-bit VIA.) Maybe andvar can test it more extensively now, though -- glxgears, x11perf, firefox, Even better if we can get a sampling of code coverage, e.g. maybe with dtrace to count function calls at least, to confirm it's actually getting exercised. 2. It's a legacy UMS driver, which is inherently sketchy (display configuration requires granting userland direct access to pci and device registers) and increasingly unmaintained even upstream. So I put in some infrastructure to allow UMS drivers to be loaded dynamically, so it wouldn't be necessary to have sketchy business like that in the kernel by default. I kind of intended to give the same treatment to the other legacy UMS drivers like mga (matrox), r128, sis, tdfx, , but it's been a very low priority so I haven't gotten a round tuit (and I only have hardware for mga and that's in a build server I don't like to mess with).

Some of us are all about the legacy hardware :) Seriously, one of the areas in which NetBSD's reputation is relatively better is in older x86 hardware, so if enabling it is likely to give a better experience for some set of hardware while being very unlikely to make things worse, I'd support enabling it David
