sections. They point to the same data in the file, but sections are
for linkers and are not necessarily present in an executable.
The original switch from phdrs to shdrs seems to be just a cop-out to
avoid parsing multiple notes per segment, which doesn't really avoid
the problem b/c sections also can contain multiple notes.
Also, use Xr to refer problib(3) in the HISTORY section instead of Nm.
While parsing the man pages, any .Nm occurrence gets replaced by the
value specified in the NAME section. Referencing individual function
names with .Nm was causing makemandb(8) to replicate the complete
NAME section for every such occurrence. This was leading to an
ugly looking snippet in apropos(1)'s output when searched for
any of these man pages.
Remove:
- add PT_SET_SIGMASK and PT_GET_SIGMASK - used by checkpointing software
This interface has been committed to HEAD.
Sponsored by <The NetBSD Foundation>
Add new interface to add ability to get/set signal mask of a tracee.
It has been inspired by Linux PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, but
adapted for NetBSD API.
This interface is used for checkpointing software to set/restore context
of a process including signal mask like criu or just to track this property
in reverse-execution software like Record and Replay Framework (rr).
Add new ATF tests for this interface
====================================
getsigmask1:
Verify that plain PT_SET_SIGMASK can be called
getsigmask2:
Verify that PT_SET_SIGMASK reports correct mask from tracee
setsigmask1:
Verify that plain PT_SET_SIGMASK can be called with empty mask
setsigmask2:
Verify that sigmask is preserved between PT_GET_SIGMASK and
PT_SET_SIGMASK
setsigmask3:
Verify that sigmask is preserved between PT_GET_SIGMASK, process
resumed and PT_SET_SIGMASK
setsigmask4:
Verify that new sigmask is visible in tracee
Kernel ABI bump delayed as there are more interfaces to come in ptrace(2).

Added entries:
- add support to read debugger events via a file descriptor in procfs
(kevent(2)), it's still useful in cases when a parent traces tracee and has
to call waitpid(2) for its child - as this clashes with GUI toolkits
- fix more calls for netbsd32 compat

file_exists_exact function was introduced in 1.26 for the benefit of
cross-building on OS X case-insensitive file system. It is extremely
slow on diskless machines. That becomes especially noticeable when
you upgrade a system that has a lot of obsolete files, it can take
literally hours.
Currently a tracer is prohibited to read and write memory of a tracee.
Prohibit reading and faking signal information.

single character symbols not recognized (e.g., input containing '&' character
where grammar doesn't define that as a symbol) - map to existing
"illegal-symbol" entry in byname[]
+ fixes to test/run_make.sh: skip test-err_* files; in the bison test phase
skip additional files that contain features not supported by bison and
inhibit new bison warning messages

- remove exect(3) from libc - there is no usecase for it
Interface has been marked obsolete and it's on the queue to be removed for.
- research what happens when a tracee masks signals (including SIGTRAP) and a
breakpoint is triggered
It has been researched and ATF tests added (signal1 .. signal10).
It's currently broken on NetBSD.
Add:
- research support PT_SYSCALL & PT_STEP combined like in Linux
There are circumstances when we want to sstep and catch syscall events.

into cpu_info directly. This concerns only {i386, Xen-i386, Xen-amd64},
because amd64 already has a direct map that is way faster than that.
There are two major issues with the global array: maxcpus entries are
allocated while it is unlikely that common i386 machines have so many
cpus, and the base VA of these entries is not cache-line-aligned, which
mostly guarantees cache-line-thrashing each time the VAs are entered.
Now the number of tmp VAs allocated is proportionate to the number of CPUs
attached (which therefore reduces memory consumption), and the base is
properly aligned.
On my 3-core AMD, the number of DC_refills_L2 events triggered when
performing 5x10^6 calls to pmap_zero_page on two dedicated cores is on
average divided by two with this patch.
Discussed on tech-kern a little.
