Constructing binaries using the bit syntax with literals sizes
that would not fit in an Uint will either cause an emulator crash
or the loading to be aborted.
Use the new TAG_o tag introduced in the previous commit to make sure
that the attempt to create huge binary literals will generate a
system_limit exception at run-time.
|
|
The handling of large values for other tags than TAG_i (integer) is
buggy. Any tag value equal to or greater than 2^40 (5 bytes) will
abort loading. Tag values fitting in 5 bytes will be truncated to 4
bytes values.
Those bugs cause real problems because the bs_init2/6 and
bs_init_bits/6 instructions unfortunately use TAG_u to encode literal
sizes (using TAG_i would have been a better choice, but it is too late
to change that now). Any binary size that cannot fit in an Uint
should cause a system_limit exception at run-time, but instead the
buggy handling will either cause an emulator crash (for values in the
range 2^32 to 2^40-1) or abort loading.
In this commit, implement overflow checking of tag values as a
preparation for fixing the binary construction instructions. If any
tag value cannot fit in an Uint (except for TAG_i), change the
tag to the special TAG_o overflow tag.

We want to make sure that a tag/type name is not defined more than
once and that we don't define too many primitive tags. Primitive
tags must be named with lowercase letters (or they will be confused
with variable names in transformations in the ops.tab file).

Attempting to construct <<0:((1 bsl 32)-1)>>, the largest bitstring
allowed in a 32 bit emulator, would cause an emulator crash because
of integer overflow.
Fix the problem by using an Uint64 to avoid integer overflow.
Do not attempt to handle construction of <<0:((1 bsl 64)-1>> in
a 64-bit emulator, because that will certainly cause the emulator
to terminate anyway because of insufficient memory.

* sverker/epmd-vxworks-select-bug/OTP-9427:
Fix epmd crash on vxworks caused by faulty argument to select
|
|
The first argument g->max_conn to select() in epmd_srv.c seems to be
wrong as it excludes the listening socket(s). Instead we keep track of
the highest fd seen.
However I still don't understand why select() started to fail for
vxworks with R14B03 when the feature of more than one listening socket
was introduced. The default is still 1 listening socket (num_sockets=1),
which would make the first argument to select() unchanged.

Fix bug in ets:delete for write_concurrency that could lead to deadlock

A trace matchspec with 'enable_trace' or 'disable_trace' in body could
cause an emulator crash if a concurrent process altered the trace
setting of the traced function by calling erlang:trace_pattern.
The effect was a deallocation of the binary holding the matchspec
program while it was running. Fixed by increasing reference count of
ms-binary in the cases when 'enable_trace' or 'disable_trace' may
cause a system block that may alter the ongoing trace.
The paradox here is that db_prog_match() is using erts_smp_block_system()
to do 'enable_trace' and 'disable_trace' in a safe (atomic) way. But that
also have the (non-atomic) effect that racing thread might block the
system and change the trace settings with erlang:trace_pattern.

Relocking in ets_delete_1() and remove_named_tab() was done by
unlocking the table without clearing the is_thread_safe flag. A racing
thread could then read-lock the table and then incorrectly
write-unlock the table as db_unlock() looked at is_thread_safe to
determine which kind of lock to unlock.
Several fixes:
1. Make db_unlock() use argument 'kind' instead of is_thread_safe to
determine lock type.
2. Make relock logic use db_lock() and db_unlock() instead of directly
accessing lock primitives.
3. Do ownership transfer earlier in ets_delete_1 to avoid racing owner
process to also start deleting the same table.

The bug was creating an invalid bignum instead of a small integer,
causing strange comparing behavior (=:= failed but == succeeded).

An experimental version of Dialyzer discovered that the atom that
replaced the DRV macro in prim_file ends up in calls to
erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The
documentation states that this call requires a string there.
This change is also consistent with the one introduced in commit
0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.

F_HIBERNATE_SCHED flag that was introduced in b7ecdcd1ae9e11b8f75e must
be cleared in hipe_mode_switch as well. Otherwise, processes running
HiPE code that hibernate, wake up and then trap into a BIF will not be
rescheduled.
