2012-10-09crypto: Make unloading of crypto saferSverker Eriksson
Facts: crypto nif-lib registers callback functions that openssl uses for memory management and thread synchronization. The callback functions can only be set once, openssl does not allow changing the callback functions. Problem: If openssl is dynamicly linked to crypto, you might get s scenario where the crypto lib is unloaded while leaving openssl loaded with its old pointers to the unloaded crypto code intact. If crypto is then reloaded (by init:restart() for example), the crypto nif-lib might get relocated at a different address. crypto calls openssl which in turn calls the old invalid callback functions...kaboom. Solution: Break apart the callback functions into a separate dynamic lib that crypto loads with dlopen. When crypto is unloaded the callback lib is left in place to be reused if/when crypto is loaded again.
2012-09-26Fix missing information in crash dump for native-compiled modulesBjörn Gustavsson
In the erl_crash.dump file, native-compiled modules did not have any information about attributes and compilation. The problem is that the code:make_stub_module/3 BIF (which is internally used when native code is loaded) did not copy the size field the attribute and compilation info chunks. Those size fields are only used when writing crash dumps.

Sometime when executing an tty io operation just before the emulator terminated, the io message would get lost. This commit makes sure that there is no io in the fd driver before shutting down.

Attempting to turn off local call trace when there was global call trace enabled would incorrectly turn off the global call trace. This bug was introduced in bf5bf8b93dccca86c4775b21ee0db49eb6a3b133.

2012-08-27make_preload: Don't fail if Perl's default file encoding is UTF-8Björn Gustavsson
Setting Perl's default encoding for files to UTF-8, for example like this: PERL_UNICODE=DS make would crash the build with a message similar to: form size 1413 greater than size 1237 of module at utils/make_preload line 175, <FILE> chunk 1. Tell Perl to interpret the data in BEAM files as binary by using the binmode() function. The binmode() function existed before Unicode support was added to Perl, which means that make_preload should work even in old versions of Perl. Noticed-by: Aaron Harnly

2012-08-17Relocate bodies of DTrace probes to the statically-linked VM.Scott Lystig Fritchie
Due to various operating systems (in both the DTrace and SystemTap worlds) not fully supporting DTrace probes (or SystemTap-compatibility mode probes) in shared libraries, we relocate those probes to the statically-linked virtual machine. This could be seen as pollution of the pristine VM by a (yet) experimental feature. However: 1. This code can be eliminated completely by the C preprocessor. 2. Leaving the probes in the dyntrace NIF shared library simply does not work correctly on too many platforms. *Many* thanks to Macneil Shonle at Basho for assisting when my RSI-injured fingers gave out. Tested on: * CentOS 5, SystemTap 1.3 * Solaris 10 (note) * Solaris 11 * OpenIndiana 151 * SmartOS 20120809T221258Z * FreeBSD 9.0-RELEASE (note) I had hoped to be able to test CentOS 6 + SystemTap 1.7, but the details of dealing with all dependencies for a 2.6.32-279.5.1.el6.x86_64 kernel are too time consuming right now. (note: Solaris 10 and FreeBSD 9.0-RELEASE can take a long time to compile)
2012-08-17Remove support for tuple funsBjörn Gustavsson
Tuple funs were deprecated in R15B (in commit a4029940e309518f5500).
2012-08-16Allow mixed IPv4 and IPv6 addresses to sctp_bindxTomas Abrahamsson
Also allow mixed address families to bind, since the first address on a multihomed sctp socket must be bound with bind, while the rest are to be bound using sctp_bindx. At least Linux supports adding address of mixing families. Make inet_set_faddress function available also when HAVE_SCTP is not defined, since we use it to find an address for bind to be able to mix ipv4 and ipv6 addresses.
2012-08-16Add checks for in6addr_any and in6addr_loopbackTomas Abrahamsson
These variables are normally declared by <netinet/in.h>, but for instance not on Windows 7, SDK 7.1. Work around that by using IN6ADDR_ANY_INIT and IN6ADDR_LOOPBACK_INIT if present, fallback to using :: and ::1.
2012-08-16Fix SCTP multihomingTomas Abrahamsson
Setting several ip addresses for an SCTP socket worked only for IPv4 on Linux. For IPv6 and for other for instance Solaris and FreeBSD, it failed with badarg for both IPv4 and IPv6. For the first address specified to gen_sctp:open, bind is now called, while for any following addresses, sctp_bindx is called, repeatedly, with one address at a time. Previously, sctp_bindx was called for all addresses in one go, with the addresses in reverse order, and bind was not called at all if more than one address was specified. Both Solaris and FreeBSD requires bind to have been called before calling sctp_bindx, and FreeBSD additionally allows at most one address at a time in the call to sctp_bindx. For some versions of Linux, for instance SuSE 10, the port can be 0 only for the call to bind but not for subsequent calls to sctp_bindx, so replace with the port number assigned by the operating system.
