of technical terms. Also add some new language improvments discussed
with the technical writer.

* sverk/ets-grow-faulty-assert/OTP-12647:
erts: Fix ets bug in debug VM
|
|
Symptom: ASSERT(segtab[seg_ix] == NULL) in alloc_seg() fails.
Remedy: Make sure we set segment pointer to NULL in free_seg()
even when we switch to smaller segtab.

A channel could be opened with the 'max packet size' set to 0. The behaviour is not defined in the ssh rfc:s, and openssh does not handle that case in some special way besides looping.
The introduced solution just "keep quiet" but removes the eternal loop that caused Erlang to core dump.
|
|
|
|
The ssh acceptor process listens for connections and
spawns a process to handle each new connection that it accepts.
The ownership of the accepted socket will be transfered to the new process
that will handle the incomming messages. Before the ownership is
transfered the socket should be in {active, false} or the acceptor
process may receive data aimed for the connection. As the accept socket
inherits the listen options we set {active, false} there.
|
|
A queue is the behaviour that we want, so this makes the code
easier to understand and more effective.
|
|
The error report was assumed to only happen if our code was wrongly
implemented "internal error". However it would also occur when
bad input was recived from the peer, and could hence cause extensive
logging on DoS attacks.

* hb/dialyzer/fix_plt_bug/OTP-12637:
dialyzer: Move a testcase to plt_SUITE
dialyzer: Update the PLT properly when a module is changed
|
|
SSI is an old technique implemented by mod_include, that was badly
tested and not recommended to use, as having the server parse HTML
pages is a double edged sword! It can be costly for a heavily loaded
server to perform parsing of HTML pages while sending
them. Furthermore, it can be considered a security risk to have
average users executing commands in the name of the Erlang node user.

Thanks to James Fish for the bug report, and to Stavros Aronis for
fixing the bug.

* anders/diameter/hardening/OTP-12628:
Remove potentially large error reason in call to diameter_lib:log/4
Limit FQDN in DiameterURI to 255 octets
Limit DiameterURI ports to 0-65535 digits on decode
Add service_opt() incoming_maxlen
Add guard to reject {spawn_opt, false} as transport/service_opt()
|
|
The function is intended to be traced on, to see abnormalities (mostly)
without producing excessive output. In the case of decode failure, the
error reason can be things like {badmatch, HugeBinary}.
Missed in commit 0058430.

* dgud/mnesia/try-catch:
mnesia: Replace catch with try-catch
|

Avoids building stacktraces where it is not needed and do
not mask errors, i.e. only catch the relevant classes in each try.

* dgud/wx/prefer-wxMSW-3/OTP-12632:
wx: Fix variable cursor constants
wx: On Mac keyboards use meta field as raw_ctrl
wx: Prefer wxWidgets-3.0. branch on windows
|
|
Fix cursor constants that changes with OS and wxWidgets releases.
|
|
On mac and wxWidgets-3.0 the crtlDown field in keyboard and
mouse events are set when command button is pressed.
The ctrl key on mac keyboard is in a field called raw_control as this
would be backward incompatible to add we reuse the metaDown field as
indicator when the ctrl keyboard button is pressed.
|
|
Since no bug fixes are done anymore on the 2.8 branch it is time
to switch the preferred version to 3.0 branch.
|
|
* dgud/observer/allocator-graphs/OTP-12631:
observer: Fix menu code (for mac)
observer: Add a new tab memory allocator charts
|
|
Have been broken since:
6fe02e14d observer: Add SASL log view for processes
|
|
Easier to the see memory usage and utilization as charts instead of
values that is updating during runtime.
Remove from system page and create a separate allocator tab.

As for the port number in the parent commit, a FQDN can't be arbitrarily
long, at most 255 octets. Make decode fail if it's more.
|
|
A port number is a 16-bit integer, but the regexp used to parse it in
commit 1590920 slavishly followed the RFC 6733 grammar in matching an
arbitrary number of digits. Make decode fail if it's anything more than
5, to avoid doing erlang:list_to_integer/1 on arbitrarily large lists.
Also make it fail if the resulting integer is outside of the expected
range.

To bound the length of incoming messages that will be decoded. A message
longer than the specified number of bytes is discarded. An
incoming_maxlen_exceeded counter is incremented to make note of the
occurrence.
The motivation is to prevent a sufficiently malicious peer from
generating significant load by sending long messages with many AVPs for
diameter to decode. The 24-bit message length header accomodates
(16#FFFFFF - 20) div 12 = 1398099
Unsigned32 AVPs for example, which the current record-valued decode is
too slow with in practice. A bound of 16#FFFF bytes allows for 5461
small AVPs, which is probably more than enough for the majority of
applications, but the default is the full 16#FFFFFF.

The most expensive part of random_ref_comp/1 is
do_matches_loop_comp/4. The running time was reduced from roughly
80 seconds to roughly 40 seconds on my computer when I modified
the caller to pre-compile the pattern.
|
|
The time to run io_proto_SUITE:unicode_options_gen/1 on my computer
was about 110 seconds. After modifying the test case so that it
does several file operations in parallel the time was reduced to
about 60 seconds.

It was possible to configure the option, but doing so caused the service
to fail when starting a watchdog process:
{function_clause,
[{diameter_service,'-spawn_opts/1-lc$^0/1-0-',
[false],
[{file,"base/diameter_service.erl"},{line,846}]},
{diameter_service,start,5,
[{file,"base/diameter_service.erl"},{line,820}]},
{diameter_service,start,3,
[{file,"base/diameter_service.erl"},{line,782}]},
{diameter_service,handle_call,3,
[{file,"base/diameter_service.erl"},{line,385}]},
{gen_server,try_handle_call,4,[{file,"gen_server.erl"},{line,607}]},
{gen_server,handle_msg,5,[{file,"gen_server.erl"},{line,639}]},
{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}]}
Tests for the option in the config suite were also missing.
Bungled in commit 78b3dc6.
