Use erts_(v)snprintf to ensure no buffer overruns in debug printouts.
Disallow everything except port and name requests from remote nodes.
Disallow kill command even from localhost if alive nodes exist.
-relaxed_command_check when starting epmd returns the possibility to
kill this epmd when nodes are alive (from localhost).
Disallow stop command completely except if -relaxed_command_check is given
when epmd was started.
Environment variable ERL_EPMD_RELAXED_COMMAND_CHECK can be set to always get
-relaxed_command_check.

* rickard/cpu-info-unbind/8765:
Fix erroneous error reports about unbind failure
|
|
On platforms where binding of schedulers is not supported, numerous error
reports on the form "Scheduler <N> failed to unbind from cpu -1: enotsup"
were erroneously issued. This bug was introduced in the 'dev' branch
before R14B (commit 1b273b618002d65159453fdfb9520a9476e4423a). That is,
the bug has never been seen in a released runtime system.

Fix faulty assertions

|
|
An assertion failed due to the thread library not being
initialized when initializing an rwmutex. This was however
harmless.
|
|
|
|
The CPU topology is now automatically detected on Windows
systems with less than 33 logical processors. The runtime system
will now, also on Windows, by default bind schedulers to logical
processors using the 'default_bind' bind type if the amount of
schedulers is at least equal to the amount of logical processors
configured, binding of schedulers is supported, and a CPU topology
is available at startup.

This has been solved by not building the SSL examples during a

As the overhead counter got larger and never really was needed in ets objects,
I removed them.

Calling erlang:system_info/1 with the new argument 'update_cpu_info'
will make the runtime system reread and update the internally stored
CPU information. For more information see the documentation of
erlang:system_info(update_cpu_info).
|
|
On Solaris/x86, the floating point exceptions bits seems to
be propagated to child threads, so if scheduler threads
use floating points exceptions, also driver threads will
have floating points exception enabled.
The problem is that erts_thread_init_float() has not been
called for driver threads, and because of that matherr()
will crash when called.
Fix matherr() so that it will work even if erts_thread_init_float()
has not been called.
This fix was suggested by Mikael Pettersson.

elib_malloc is an alternate memory allocator that
is no longer possible to build.
|
|
The mem_drv driver was only useful when elib_malloc was
active.
|
|
A long time ago, the Erlang run-time system could be
build with pre-ANSI/ISO-C (K&R) C compilers, but that is
no longer possible. Remove the remaining uses of the
compatibility macros that made it possible that possible.
|
|
The header file erts/emulator/beam/decl.h is no longer used.
|
|
It's been reported that HiPE-enabled Erlang VMs running on BSD
systems sometimes generate messages like
Yikes! erts_alloc() returned misaligned address 0x8016a512c
These originate from hipe_bif0.c:hipe_bifs_alloc_data_2().
A native code module has an associated data area of some
size and alignment. In the case where the size is zero,
the alignment is irrelevant, but the allocation BIF checks
it anyway. The warning then triggers on systems where
malloc(0) returns blocks with less alignment than we
(erroneously) expected.
The fix is to simply skip the allocation in this case and
return NULL. The loader won't actually use the address in
this case so that's safe. This is also an optimization since
it avoids allocating memory that cannot be used, and it avoids
fragmenting the system heap with useless tiny blocks.
A second problem is that the warning message failed to
identify its origin. Fixed by prefixing the message by
the BIF's name rather than the silly Yikes! string.
Tested and confirmed to solve the original reporter's problem.

This will reduce the risk of integer wrapping in bin vheap counting.
The vheap size series will now use the golden ratio instead of doubling
and fibonacci sequences.

* bjorn/remove-obsolete-driver-support/OTP-8758:
Remove obsolete/driver.h and the associated functionality
|
|
For a short period of time no_empty_run_queues may have
been increased twice for a specific run queue. Two
assertions did not take this into account.

The obsolete/driver.h header file has been obsolete
since R8B.
Remove that file, along with obsolete thread APIs for
drivers in the emulator and the test cases.
