Kees Cook 3b4a59c4b5 ptrace.2, sigaction.2, seccomp.2: Ptrace and siginfo details
While writing some additional seccomp tests, I realized
PTRACE_EVENT_SECCOMP wasn't documented yet. Fixed this, and added
additional notes related to ptrace events SIGTRAP details.

Michael Kerrisk 051ec121f0 ptrace.2: Make it clearer that glibc and syscall APIs differ for PTRACE_PEEK*
Thanks to Denys Vlasenko's additions in 78686915ae
this page does note that the glibc API for PTRACE_PEEK*
differs from the raw syscall interface. But, as the report
at https://bugzilla.kernel.org/show_bug.cgi?id=70801 shows,
this information could be more obvious. This patch makes its so.

For every PTRACE_O_TRACEfoo option, mention that old-style SIGSTOP
is replaced by PTRACE_EVENT_STOP if PTRACE_SEIZE attach was used.

PTRACE_EVENT_STOP.

So change "userspace" to "user space" or, when used
attributively, "user-space".

Denys Vlasenko ca302d0ee3 ptrace.2: Explain WNOHANG behavior and EINTR bug
I didn't like ithe "SIGKILL operates similarly, with exceptions"
phrase (if it's different, then it's not "similar", right?),
and now I got around to changing it. Now it says simply:
"SIGKILL does not generate signal-delivery-stop and therefore
the tracer can't suppress it."

Replaced "why WNOHANG is not reliable" example with a more
realistic one (the one which actually inspired to add this
information to man page in the first place): we got
ESRCH - process is gone! - but waitpid(WNOHANG) can still
confusingly return 0 "no processes to wait for".

Replaced "This means that unneeded trailing arguments may
be omitted" part with a much better recommendation
to never do that and to supply zero arguments instead.
(The part about "undocumentedness" of gcc behavior was bogus,
btw - deleted).

Expanded BUGS section with the explanation and an example
of visible strace behavior on the buggy syscalls which
exit with EINTR on ptrace attach. I hope this will lead
to people submitting better bug reports to lkml about
such syscalls.

Denys Vlasenko b16ecdae13 ptrace.2: Various fixes
For some reason, the PTRACE_TRACEME paragraph talks about some
general aspects of ptraced process behavior. It repeats the
"tracee stops on every signal" information even though that was
already explained just a few paragraphs before. Then it describes
legacy SIGTRAP on execve().

This patch deletes the first part, and moves the second part up,
into the general ptrace description. It also adds
"If PTRACE_O_TRACEEXEC option is not in effect" to the description
of the legacy SIGTRAP on execve().

The patch also amends the part which says "For requests other
than PTRACE_KILL, the tracee must be stopped." - PTRACE_ATTACH
also doesn't require that.

Denys Vlasenko 4d12a715f2 ptrace.2: add extended description of various ptrace quirks
Changes include:

s/parent/tracer/g, s/child/tracee/g - ptrace interface now
is sufficiently cleaned up to not treat tracing process
as parent.

Deleted several outright false statements:
- pid 1 can be traced
- tracer is not shown as parent in ps output
- PTRACE_ATTACH is not "the same behavior as if tracee had done
  a PTRACE_TRACEME": PTRACE_ATTACH delivers a SIGSTOP.
- SIGSTOP _can_ be injected.
- Removed mentions of SunOS and Solaris as irrelevant.
- Added a few more known bugs.

Added a large block of text in DESCRIPTION which doesn't focus
on mechanical description of each flag and operation, but rather
tries to describe a bigger picture. The targeted audience is
a person which is reasonably knowledgeable in Unix but did not
spend years working with ptrace, and thus may be unaware of its
quirks. This text went through several iterations of review by
Oleg Nesterov and Tejun Heo.
This block of text intentionally uses as little markup as possible,
otherwise future modifications to it will be very hard to make.
