* egil/fix-getifaddrs-realloc/OTP-12445:
erts: Fix getifaddrs realloc ptr mismatch
|
|
* egil/fix-child_setup-close/OTP-12446:
erts: Use closefrom() if available when closing fds
erts: Don't close all fds twice in child_setup
|
|
When a buffer was exhausted and subsequently a realloc, we could get
an invalid pointer.
For this to occur we would need to have a realloc to lower adresses.
The symptom would be garbage returned from erlang:port_control(Port, 25, [])
(prim_inet:getifaddrs(Port) resulting in a badarg) or a segmentation fault.
|
|
closefrom() was only used in the vfork() case before, now also
used in the fork() case.
|
|
The commit c2b4eab25c907f453a394d382c04cd04e6c06b49 introduced an error
in which child_setup erroneously tried to close all file descriptors twice.

* mikpe/hipe-arm-interworking:
hipe: fix ARM/Thumb interworking
|
|
* dotsimon/sctp_paddrinfo_state:
Fix inet:getopts involving #sctp_paddrinfo{}
|
|
The intention of this callback is to close all sockets associated to
a port. It is closed only on crashdumps.
This will currently only be used for the epmd port.

HiPE on ARM is currently severely broken if the rest of the VM is
compiled to run in Thumb mode -- calling native code quickly ends
up executing code in the wrong mode and crashing the VM. This is
a problem on e.g. Ubuntu which configures its system GCC to generate
Thumb by default. It can also be triggered by overriding CC or
CFLAGS when compiling the VM.
There were three issues that caused the breakage:
1. Assembly-coded functions in hipe_arm_glue.S weren't explicitly
tagged as functions, preventing the linker from generating the
correct mode-switching call instructions for calls from C to
these functions.
Fixed by tagging those symbols as functions.
2. A few BIF wrappers were so simple that they performed tailcalls
to the C BIFs. This fails to switch mode when C is in Thumb.
Fixed by performing ordinary recursive calls when C is in Thumb.
3. The assembly-coded source files weren't explicitly tagged as ARM.
Tested with the HiPE testsuite on ARMv7, with the VM built as ARM
and as Thumb. Also manually inspected the object code for the beam
executable and checked that call sites from C to HiPE's ARM runtime
code and vice versa used the correct mode-switching instructions.

The 64-bit atomic ops API is implemented by
* native word size atomic ops on 64-bit architectures, and
* native double word size atomic ops on 32-bit architectures
when available. When native double word size atomic is not
available, the fallback using modification counters is
used.

* lukas/erts/isfinite-fix/OTP-12268:
erts: Fix finite warning for clang
|
|
clang aka llvm claims to be __GNUC__ and thus we have to
explicitly check that it is not used.
|
|
* lukas/erts/bif_info_rebuild/OTP-12344:
Sort keys before generating
|
|
* vinoski/rm-foo-dtrace:
Clean up temporary dtrace file during config
|
|
* sverk/port_get_data-race/OTP-12208:
erts: Fix port data memory allocation bug
|
|
When configuring erts to support dynamic trace via dtrace, be sure to clean
up the temporary file "erts/foo-dtrace.h" used to help check for dtrace
support. Otherwise, it shows up as an untracked file in git.
|
|
This has to be done in order to consistently generate the same
file so that we do not get rebuilds all the time.

Don't use both HAVE_SYSTEMD_DAEMON and HAVE_SYSTEMD_SD_DAEMON - use only
the former one and remove the latter one entirely.

* lukas/erts/isfinite-fix/OTP-12268:
erts: Use finite instead of isfinite with gcc
|
|
Turns out that isfinite emits a function call and not
an instruction in gcc, this makes estone float arith
about 50-75% slower. finite emits the instruction so
we use that instead.
