2011-02-21Add patch from Per HedelandPatrik Nyblom
Per H @ Tail-f: The original code here had problems that possibly only occur if you abuse it for non-INET sockets, but anyway: a) If the getsockopt for SO_PRIORITY or IP_TOS failed, the actual requested setsockopt was never even attempted. b) If {get,set}sockopt for one of IP_TOS and SO_PRIORITY failed, but ditto for the other worked and that was actually the requested option, failure was still reported to erlang.

2010-12-02Stop using uncertain flags for getaddrinfo()Raimo Niskanen
The AI_V4MAPPED flag is falling out of grace in modern IPv6 stacks, for security reasons, e.g. FreeBSD do not document it any longer. The AI_ADDRCONFIG flag have got unclear semantics on the same OS.

2010-11-09Fix building error of SCTP in FreeBSD 7.1 and laterKenji Rikitake
This patch fixes building error of SCTP in FreeBSD 7.1 and later. See http://www.erlang.org/cgi-bin/ezmlm-cgi?2:mss:1257:200904:hppnfialjjdlgecdiehe for the details. R13A patch for solving a compilation error when building erts/emulator/drivers/common/inet_drv.c by Kenji Rikitake 12-APR-2009 Symptom solved by this patch: When building R13A in FreeBSD 7.1-RELEASE, the compiler flag HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_SACKDELAY is NOT enabled. Some code in erts/emulator/drivers/common/inet_drv.c incorrectly assumes HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_SACKDELAY is always true when HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_FLAGS is true in config.h. This assumption causes a compilation error.
2010-10-14Add Win32 support for hard and symbolic file system linksBlaine Whittle
Hard linking requires XP or later and a NTFS formatted drive. Symbolic linking requires Windows Vista, Windows Server 2008, Windows 7 or later. Symbolic linking on earlier versions of Windows will return {error, enotsup}. file:make_link/2, file:make_sym_link/2 and file:read_link/1 are all implemented. file:read_file_info/1 does NOT return the number of hard links on the file as this results in performance problems for read_file_info/1, however this can be enabled by uncommenting a few lines of code. The original path was submitted on 9/2/2009 by Alex Tearse-Doyle.
2010-09-30Fix appending to large files (>4GB) on WindowsJuhani Rankimies
Append mode doesn't work for files larger that 4GB on Windows. Caused by incorrect usage of SetFilePointer in win_efile.c. Fix uses OVERLAPPED structure to specify write position (EOF). http://msdn.microsoft.com/en-us/library/aa365747.aspx Opening file in append mode was also considered, but rejected, because it might cause backwards incompatibility by limiting applicable operations on the descriptor. SetFilePointerEx was not used because it would caused more system calls than using OVERLAPPED structure.
2010-09-09Make gen_tcp:recv/2 consistent with ssl:recv/2Björn Gustavsson
When the HTTP packet mode has been enabled for a socket, the ssl and gen_tcp modules have different error indications when there is an error while parsing the HTTP header: ssl:recv(SSLSocket, 0) -> {ok, {http_error, _Str}} gen_tcp:recv(Socket, 0) -> {error, {http_error, _Str}} We have decided to change gen_tcp:recv/2 to behave the same way as ssl:recv/2. That means that there will be always be an ok tuple if data could be succefully read from the socket, and an error tuple if there was a read error at the socket level.

2010-09-03inet: support retrieving MAC address on BSDMichael Santos
On systems supporting getaddrinfo(), support looking up the MAC address from inet:ifget/2. The results have the same quirks as with Linux: if the MAC address is longer than 6 bytes (e.g., fw0 under Mac OS X), the address is truncated; if the interface does not have a MAC address (e.g., lo0), an address consisting of 0's is returned.

The assoc_id field was uninitialized causing random answers.
2010-08-31Fix SCTP linger optionRaimo Niskanen
inet:setopts(S, [{linger,{true,2}}]) returned {error,einval} for SCTP sockets. The inet_drv had a bug when checking the option size.
2010-08-17erts: Remove the unused mem_drv driverBjörn Gustavsson
The mem_drv driver was only useful when elib_malloc was active.
2010-08-17erts: Remove stray pre-ISO-C compatibility macrosBjörn Gustavsson
A long time ago, the Erlang run-time system could be build with pre-ANSI/ISO-C (K&R) C compilers, but that is no longer possible. Remove the remaining uses of the compatibility macros that made it possible that possible.
2010-07-26inet: fix getservbyname buffer overflowMichael Santos
The byte holding the length of the interface name for the getservbyname/2 function is used in a signed context and can become negative, causing the buffer to be overrun. Make the same change for getservbyport/2. Test case: inet:getservbyname(list_to_atom(lists:flatten(lists:duplicate(128, "x"))), tcp).
2010-07-26inet: fix ifr_name buffer overflowMichael Santos
The byte holding the length of the interface name for the ifget/2 functions is used in a signed context and can become negative, causing the ifreq.ifr_name buffer to be overrun. Test case: inet:ifget(lists:duplicate(128, "x"), [addr]).
2010-07-26inet: null terminate ifr_name bufferMichael Santos
The buffer holding the interface name should be null terminated. See man 7 socket on Linux or the definition of IFNAMSIZ in net/if.h on FreeBSD: Length of interface external name, including terminating '\0'.
2010-07-07Fix inet_drv to detect passive mode UDP errors for SCTP buildsRaimo Niskanen
Debug and patch by Per Hedeland for R13B04 on erlang-patches: Connected UDP (and handling of any other errors in UDP recv()) is broken in passive mode for all SCTP-enabled builds.
2010-06-04Support opening files in exclusive modeMichael Santos
Add an option that atomically tests for the existence of a file and creates it if the file does not exist, by passing the O_EXCL flag to open() on Unix and CREATE_NEW flag on Windows. Support for O_EXCL varies across platforms and filesystems. {ok, Fd} = file:open("/tmp/foo", [write,exclusive]), {error, eexist} = file:open("/tmp/foo", [write,exclusive]).

2010-05-27inet_drv.c: Remove red herringBjörn Gustavsson
Remove redundant "!defined(__WIN32__)". It is used inside the #else branch of a "#ifdef __WIN32__", so it serves no useful purpose except to fool unsuspecting readers.
2010-05-27use macro to portably test for socket system call errorsSteve Vinoski
On some combinations of Montavista Linux running on Cavium Octeon chips, some socket-related system calls erroneously return negative numbers other than -1 to indicate errors, but inet_drv.c specifically compares against -1 to test for errors. The result is that beam dumps core due to the code treating these negative numbers as success indicators, as counts/offsets of bytes written, etc. thereby corrupting its own internal data structures. To fix this, introduce a portability macro to test the result of socket system calls. The test remains unchanged on Windows but for other platforms the macro considers all return values that are less than zero to be errors. Though POSIX specifies that errors from these system calls are indicated by a return value of -1, treating all negative return values as errors is also safe, as described in detail below. In networking programming, treating all negative return values from system calls as errors is very common practice -- see the examples in W. Richard Stevens's popular and highly lauded network programming books, for example. For system calls that return 0 to indicate success, treating all negative numbers as errors is safe because only 0 is specified to indicate success. These include: getsockname getpeername getsockopt gethostname bind listen connect close shutdown Likewise, for system calls that return non-negative numbers to indicate success, treating all negative numbers as errors is also safe. These functions typically return signed integers of type ssize_t, and they treat any parameters of type size_t that cannot fit within the ssize_t return value, such as numbers of bytes to read or write, as errors (specifically EINVAL). For example, in the "ERRORS" section of the man page for writev from several varieties of Linux, it states that EINVAL is returned when the total length of the I/O is more than can be expressed by the ssize_t return value. These calls include: recv recvfrom recvmsg writev send sendto sendmsg Finaly, the socket() system call is also similar to these in that it returns a signed type (int) with all non-negative return values indicating success, so treating all negative return values as errors is safe.

2010-05-20Add file:advise/4 - a wrapper to the POSIX syscall posix_fadviseFilipe David Manana
Useful for informing the Operating System about the access pattern for a file's data, so that it can adapt the caching strategy to maximize disk IO performance.
2010-05-20Add file:datasync/1 for syncing file contents onlyFilipe David Manana
file:datasync/1 invokes the POSIX system call "int fdatasync(int fd)". This system call is similar to "fsync" but, unlike fsync, it does not update the metadata associated with the file (like the access time for example). It's used by many DBMSs (MySQL and SQLite of example) to increase disk IO performance, as it avoids disk seeks and disk write operations compared to fsync. More details on it at: http://linux.die.net/man/2/fdatasync An example, from the MySQL source: http://bazaar.launchpad.net/~mysql/mysql-server/mysql-5.1-telco-6.1/annotate/head%3A/mysys/my_sync.c#L61 This new function just calls fsync on systems not implementing fdatasync.
