* john/erts/fix-literal-map-elements/OTP-15184:
Fix a rare crash when matching on literal maps
|
|
|
|
When matching on a literal map, the map is placed into the general
scratch register first. This is fine in isolation, but when the
key to be matched was in a Y register it would also be placed in
the scratch register, overwriting the map and crashing the
emulator.

The release notes generated in the README and notes.xml were out of
sync, and notes.xml erroneously listed a fixed bug as open.

This is a hack to make the "noshell" option work; kqueue can poll
these fds but will not report EV_EOF. This may be common to all
all pipes but we have no way to tell whether an fd is a pipe or
not.

The counter used for generating async operation ids was a plain int
shared between all ports, which was incorrect but mostly worked
fine since the ids only had to be unique on a per-port basis.
However, some compilers (notably GCC 8.1.1) generated code that
assumed that this value didn't change between reads. Using a
shortened version of enq_async_w_tmo as an example:
int id = async_ref++;
op->id = id; //A
return id; //B
In GCC 7 and earlier, `async_ref` would be read once and assigned
to `id` before being incremented, which kept the values at A and B
consistent. In GCC 8, `async_ref` was read when assigned at A and
read again at B, and then incremented, which made them inconsistent
if we raced with another port.
This commit fixes the issue by removing `async_ref` altogether and
replacing it with a per-port counter which makes it impossible to
race with someone else.

When a system task was enqueued on a process between being
scheduled and the check altered in this commit, we'd run dirty
code on a normal scheduler as the RUNNING_SYS flag wasn't set
and we wouldn't migrate back.
This change migrates us to a dirty scheduler instead, which will
immediately bounce us back to a normal scheduler where
RUNNING_SYS will be set appropriately.
This is caught fairly reliably by
process_SUITE:system_task_failed_enqueue on machines with a lot of
cores.

The fail state wasn't re-checked in the state change loop; only
the FREE state was checked. In addition to that, we would leave
the task in the queue when bailing out which could lead to a
double-free.
This commit backports active_sys_enqueue from master to make it
easier to merge onwards.
|
|
When scheduled out, the process was never checked for the FREE state
before rescheduling, which meant that a system task could sneak in
and cause a double-free later on.

that could cause clearing of fd-bits past allocated bit-vectors.
