PT_LWPINFO is a legacy ptrace(2) operation that was originally intended to retrieve the thread (LWP) information inside a traced process. It has a number of flaws and is confused with PT_LWPINFO from FreeBSD. PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename, removal of pl_event) and introduces new features: signal context (pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address (pl_private). The private pointer was so far missing information for a debugger. PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific information, so far missed in the core(5) files. PT_LWPSTATUS retrieves LWP information for the prompted thread. PT_LWPNEXT retrieves LWP information for the next thread, borrowing the semantics from NetBSD specific PT_LWPINFO. PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for the foreseeable future, without plans of removing it. Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT. Keep ATF tests for PT_LWPINFO. Switch GDB to new API. Proposed on tech-kern@.
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.
