ptrace.2: Do not say that PTRACE_O_TRACESYSGOOD may not work
...
Remove the old statement that PTRACE_O_TRACESYSGOOD may not work
on all architectures. As far as I can tell, all kernel code
properly tests PT_TRACESYSGOOD flag and sets the 7th bit in the
exit code passed to ptrace_notify().

ptrace.2: BUGS: ptrace() may set errno to zero
...
ptrace() with requests PTRACE_PEEKTEXT, PTRACE_PEEKDATA and
PTRACE_PEEKUSER can set errno to zero. AFAICS this is for a good
reason (so that you can tell the difference between a successful
PEEK with a result of -1 and a failed PEEK, even if you forget to
clear errno yourself), but it technically violates the rules
described in the errno.3 manpage.
glibc snippet from sysdeps/unix/sysv/linux/ptrace.c:
res = INLINE_SYSCALL (ptrace, 4, request, pid, addr, data);
if (res >= 0 && request > 0 && request < 4)
{
__set_errno (0);
return ret;
}
reproducer:
$ cat ptrace_test.c
char foobar_data[4] = "ABCD";
int main(void) {
pid_t child = fork();
if (child == -1) err(1, "fork");
if (child == 0) {
if (prctl(PR_SET_PDEATHSIG, SIGKILL)) err(1, "prctl");
while (1) sleep(1);
}
int status;
if (ptrace(PTRACE_ATTACH, child, NULL, NULL)) err(1, "attach");
if (waitpid(child, &status, 0) != child) err(1, "wait");
errno = EINVAL;
unsigned int res = ptrace(PTRACE_PEEKDATA, child, foobar_data, NULL);
printf("errno after PEEKDATA: %d\n", errno);
printf("PEEKDATA result: 0x%x\n", res);
}
$ gcc -o ptrace_test ptrace_test.c -Wall
$ ./ptrace_test
errno after PEEKDATA: 0
PEEKDATA result: 0x44434241

ptrace.2: Copy retval info for SECCOMP_GET_FILTER to right section
...
The "RETURN VALUE" section made a claim that was incorrect for
PTRACE_SECCOMP_GET_FILTER. Explicitly describe the behavior of
PTRACE_SECCOMP_GET_FILTER in the "RETURN VALUE" section (as
usual), but leave the now duplicate description in the section
describing PTRACE_SECCOMP_GET_FILTER, since the
PTRACE_SECCOMP_GET_FILTER section would otherwise probably become
harder to understand.

ptrace.2: clarify PTRACE_O_EXITKILL
...
The description in the man page is confusing; it makes it sound like
setting the PTRACE_O_EXITKILL flag on any tracee makes it so that all
tracees are killed if the tracer exits. The description from kernel
commit 992fb6e170639b that introduced PTRACE_O_EXITKILL offers a
different explanation: "If the tracer exits it sends SIGKILL to every
tracee which has this bit set".

ptrace.2: Expand documentation PTRACE_EVENT_SECCOMP traps
...
In Linux 4.8 (through a series of commits, 93e35efb8de45393c
being the actual reordering on x86), the order of
PTRACE_EVENT_SECCOMP and syscall-entry-stops was reversed.
Document both behaviors and their interaction with the
various forms of restart.

ptrace.2: Various fixes after review by Jann Horn
...
Among other things, Jann pointed out that the commoncap LSM
is always invoked, and Kees Cook pointed out the relevant
kernel code:
===
> BTW, can you point me at the piece(s) of kernel code that show that
> "commoncap" is always invoked in addition to any other LSM that has
> been installed?
It's not entirely obvious, but the bottom of security/commoncap.c shows:
struct security_hook_list capability_hooks[] = {
LSM_HOOK_INIT(capable, cap_capable),
...
};
void __init capability_add_hooks(void)
{
security_add_hooks(capability_hooks, ARRAY_SIZE(capability_hooks));
}
And security/security.c shows the initialization order of the LSMs:
int __init security_init(void)
{
pr_info("Security Framework initialized\n");
/*
* Load minor LSMs, with the capability module always first.
*/
capability_add_hooks();
yama_add_hooks();
loadpin_add_hooks();
/*
* Load all the remaining security modules.
*/
do_security_initcalls();
return 0;
}

ptrace.2: Clarify the purpose of mentioning the kernel PTRACE_MODE_* constants
...
The "ptrace access mode" text is about user-space-visible
behavior, but in order to explain that behavior at what I
believe is a sufficient level of detail (e.g., to differentiate
the various types of checks that are performed for various
system calls and pseudofile accesses), one needs (1) to discuss
the MODE flag details as implemented in the kernel, and (2) to
have a shorthand way to refer to the various cases from other
pages. It's not absolutely necessary to name the flags for (1),
but using the flag names is certainly a handy shorthand for (2).
