Arrange to update cached LWP credentials in userret() rather than during
syscall/trap entry, eliminating a test+branch on every syscall/trap.

This wasn't possible in the 3.99.x timeframe when l->l_cred came about
because there wasn't a reliable/timely way to force an ONPROC LWP running on
a remote CPU into the kernel (which is just about the only new thing in
this scheme).

Centralized shared part of child_return() into MI part

Add a new function md_child_return() for MD specific bits only.

New child_return() is now part of MI and central code that handles
uniformly tracing code (KTR and ptrace(2)).

Synchronize value passed to ktrsysret() among ports to SYS_fork. This is
a traditional value and accessing p_lflag to check for PL_PPWAIT shall
use locking against proc_lock. Returning SYS_fork vs SYS_vfork still isn't
correct enough as there are more entry points to forking code. Instead of
making it too good, just settle with plain SYS_fork for all ports.

Revision 1.54 / (download) - annotate - [select for diffs], Wed Apr 3 08:08:00 2019 UTC (5 years ago) by kamil

Rework the fork(2)/vfork(2) event signalling under ptrace(2)

Remove the constraint of SIGTRAP event being maskable by a tracee.

Now all SIGTRAP TRAP_CHLD events are delivered to debugger.

This code touches MD specific logic and the child_return routine.
It's an intermediate step with a room for refactoring in future and
right now the least invasive approach. This allows to assert expected
behavior in already existing ATF tests and make the code prettier
in future keeping the same semantics. Probably there is a need for a MI
wrapper of child_return for shared functionality between ports.

Add a new vp-private flag, SAVP_FLAG_DELIVERING. This flag indicates
that the vp is in the process of delivering a new-thread upcall.
This is a BLOCKED or NEWPROC upcall. Do NOT generate any BLOCKED
upcalls while this is set. Set it at the end of sa_switchcall()
and clear it at syscall entry. Sadly, I have found no other
way to handle this. The old SA interface has no way for
userland to acknowledge that it got the upcall, so use syscall
entry as the indicator that libpthread got it.

This addresses the issue seen on current-users with firefox
dying with a blockedgen != unbockedgen error. The problem is we
deliver a BLOCKED upcall, but between the end of userret()
and when the CPU indicates that it's running in user mode, we take
a page fault. Said page fault blocks, blocking upcall delivery.
The original block, however, was short-lived, and the UNBLOCK
happens shortly. It happens before libpthread actually notices
the BLOCKED upcall. Boom!

Unfortunately a LOCKDEBUG/DIAGNOSTIC kernel still dies before
firefox opens. However this new issue is with uvm code calling
mtsleep when not holding a correct lock; sa_switch() is exploding
at KASSERT(lwp_locked(l, NULL)); before it's done _anything_.

Also, while here, add sa_system_disabled. This is an integer
that we examine when starting SA for a proc. If it's non-zero,
we error out. Once this is hooked into sysctl, you'll be able to
disable SA w/o recompiling.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

PR/29607: Christian Biere systrace doesn't handle interrupted syscalls properly
Instead of jumping to the default "bad" case, jump to the error handling
switch, so that we can deal with ERESTART/EJUSTRETURN properly.

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Add a realcode argument to trace_enter and ktrsyscall. realcode is the
original system call number, which can be negative for a Mach trap.
We cannot just replace code by realcode, because ktrsyscall uses it as
an index in the system call table, thus crashing the kernel when the
value is negative.

Added support for Darwin's PowerPC-only system calls:
ppccalls, with system call numbers starting at 0x6000
fasttraps, with system call numbers starting at 0x7FF0

Because the Mach system call dispatching code has grown a bit
too much, introduce an inline function to handle it (mach_syscall_dispatch).

While we are there, remove the Mach and Linux includes from
arch/powerpc/powerpc/syscall.c and push them into
arch/powerpc/powerpc/{mach|linux}_syscall.c
