2012-08-30Teach VM not to dump core on long pathnamesPatrik Nyblom
Long input paths (longer than MAX_PATH) would get copied into a buffer of size MAX_PATH for read_link and altname in efile_drv. Also fixed misuse of size_t parameter as wchar_t * string length in win_efile:efile_readlink.

* tab/fix-sctp-multihoming-IPv6/OTP-10217: Allow mixed IPv4 and IPv6 addresses to sctp_bindx Add checks for in6addr_any and in6addr_loopback Fix SCTP multihoming inet_drv.c: Set sockaddr lengths in inet_set_[f]address
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.

Incorrect window was used to calculate x position.
2012-05-31inet_drv.c: Set sockaddr lengths in inet_set_[f]addressTomas Abrahamsson
Set appropriate values for the sockaddr length fields---sai.sin_len and sai6.sin6_len---if those fields exist; rely on the NO_SA_LEN configure check to see if they exist. The length field exists on at least FreeBSD, and there it needs to have a proper value for instance in the call to sctp_bindx, or else that will fail with EINVAL.

Ensure displayed sizes are not negative.
2012-05-04gen_tcp: Make setopts(S,[{active,once}]) try a readPatrik Nyblom
This significantly reduces latency for tcp servers with high load, as we need not go into poll to get the next message. Maximum throughput may increase between 4 to 6 times compared to R15B.

2012-03-22Add user tag spreading functionality to VM and use in filePatrik Nyblom
User tags in a dynamic trace enabled VM are spread throughout the system in the same way as seq_trace tokens. This is used by the file module and various other modules to get hold of the tag from the user process without changing the protocol.

2012-03-20Fix reselecting bug on OS XLukas Larsson
Since stop_select is called at an arbitrary point in the future it would sometime not be alled before the tcp driver started selecting on the fd. So now ERL_DRV_USE_NO_CALLBACK is used so that the stop_select call is never made. This seems to only have happened OS X.

2012-03-20Fix memory leak when sendfile process crashesLukas Larsson
We use the fact that file_flush is called when there is data in the driver queue when a port is closed to ensure that all data is cleaned up as it should. OTP-9993

2012-03-15Fix port leaks in zlibSverker Eriksson
zip,unzip,gzip,gunzip,compress and uncompress did not close the port when given invalid data argument. Fixed by putting close in "try-after". A closed port could in same cases get stuck in limbo due to data in io-queue. Fixed by adding a flush callback.
2012-02-21Add missing HAVE_IN6 && AF_INET6 ifdefPeer Stritzinger
This prevents building for operating systems that do not yet have IPv6 compatible socket API. Error can be reproduced by (cross)building for a os that doesn't have these headers. This will abort with a error about incomplete type 'struct in6_addr'. All other uses of IPv6 API in inet_drv.c are conditionalized like in the patch.

2012-01-04Fix returned error from gen_tcp:accept/1,2 when running out of portsPer Hedeland
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.
