ubc_fault_page(): Ignore PG_RDONLY flag and always pmap_enter() the page with the permissions of the original access_type. It is the file system's responsibility to allocate blocks that is being modified by write(), before calling into UBC to fill the pages for that range. KASSERT() is added there to confirm that no clean page is mapped writable. Fix infinite loop in uvm_fault_internal(), observed on 16KB-page systems, where it continues to try to make a partially-backed page writable. No regression in ATF and KASSERT() does not fire on several architectures, as far as I can see. Fix suggested by chs. Thanks! |

NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ freenode.
