2016-03-02Skips any sockets with unsupported protocols.Ingela Anderton Andin
Patch from end of PR 864 Fixes problem reported in the PR by jeckersb In this error case, a negative file descriptor is now saved at listensock[i], which leads to a buffer overflow later on at https://github.com/msantos/otp/blob/epmd-IPv6-node-reg2/erts/epmd/src/epmd_srv.c#L498 when calling FD_ISSET(listensock[i],&read_mask). To reproduce this: Completely disable IPv6 with ipv6.disable=1 on the kernel command line Build with fortified code (RHEL/CentOS default): CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fno-strict-aliasing'

2016-02-25Add erl_prim_loader:get_modules/3Björn Gustavsson
When we are going to implement functions that can load many modules at once, we don't the erl_prim_loader server to become a bottleneck. Therefore, we need erl_prim_loader:get_modules/3 that can read many BEAM files in parallel. Note that we will not bother making reading from archive files or using the inet loader efficient. That can be done later if it turns out to be important.
2016-02-25Add has_prepared_code_on_load/1 BIFBjörn Gustavsson
2016-02-25Allow erlang:finish_loading/1 to load more than one moduleBjörn Gustavsson
The BIFs prepare_loading/2 and finish_loading/1 have been designed to allow fast loading in parallel of many modules. Because of the complications with on_load functions, the initial implementation of finish_loading/1 only allowed a single element in the list of prepared modules. finish_loading/1 does not suspend other processes, but it must wait for all schedulers to pass a write barrier ("thread progress"). The time for all schedulers to pass the write barrier is highly variable, depending on what kind of code they are executing. Therefore, allowing finish_loading/1 to finish the loading for more than one module before passing the write barrier could potentially be much faster than calling finish_loading/1 multiple times. The test case many/1 run on my computer shows that with "heavy load", finish loading of 100 modules in parallel is almost 50 times faster than loading them sequentially. With "light load", the gain is still almost 10 times. Here follows an actual sample of the output from the test case on my computer (an 2012 iMac): Light load ========== Sequential: 22361 µs Parallel: 2586 µs Ratio: 9 Heavy load ========== Sequential: 254512 µs Parallel: 5246 µs Ratio: 49

2016-02-24erts: Make erlang:halt() accept bignums as StatusSverker Eriksson
Just mask away the high bits to get a more tolerant erlang:halt that behaves the same on 32 and 64 bit architectures.
2016-02-24erts: Change erl_exit into erts_exitSverker Eriksson
This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).
