2011-12-06erts: Remove truncation of http packet parsing and return error insteadSverker Eriksson
This is a slight modification of previous commit by Steve Vinoski For backward compatibility of old users of decode_packet, I think it's enough to return error instead of keeping the old line truncation behaviour.

Thanks Tuncer Ayaz
2011-12-05Make solaris use sendfilevLukas Larsson
sendfilev is a richer API which allows us to do non blocking TCP on solaris. The normal sendfile API seems to have some issue with non blocking sockets and the return value of sendfile.

2011-12-05honor packet_size for http packet parsing to fix OTP-9389Steve Vinoski
Allow applications to use a packet_size setting on a socket to control acceptable HTTP header line length. This gives them the ability to accept HTTP headers larger than the default settings allow, but also lets them avoid DOS attacks by accepting header lines only up to whatever length they wish to allow. Without this change, if an HTTP request/response line or header arrives on a socket in http, http_bin, httph, or httph_bin parsing mode, and the request/response line or header is too long to fit into a default inet_drv buffer of 1460 bytes, an unexpected error occurs. These problems were described and discussed on erlang-questions in June 2011 in this thread: http://erlang.org/pipermail/erlang-questions/2011-June/059563.html In the original code, no buffer reallocation occurs to enlarge the buffer, even if packet_size or line_length are set in a way that should allow the HTTP data to be parsed properly. The only available workaround was to collect headers and parse them using erlang:decode_packet, but that approach has drawbacks such as having to collect all HTTP header data before it can be handed to decode_packet for correct parsing, and also requiring each and every Erlang web server developer/maintainer to add the workaround to his or her web server. Change the packet parser to honor the packet_size setting for HTTP parsing. If packet_size is set, and an HTTP request/response or header line exceeds the default 1460 byte TCP buffer limit, return an indication to tcp_remain that it should realloc the buffer to enlarge it to packet_size. Also fix the HTTP parsing code to properly honor line_length by truncating any HTTP request/response or header lines that exceed that setting. For backward compatibility, default behavior is unchanged; if an application wants to be able to accept long HTTP header lines, it must set packet_size to an appropriate value. Buffer reallocation occurs only when needed, so the original default buffer size in the code is still the default. Make the line mode parsing honor packet_size as well, for consistency. Add new regression tests to the emulator decode_packet suite and also to the kernel gen_tcp_misc suite. The documentation for packet_size in inet:setopts/2 is already sufficient. Many thanks to Sverker Eriksson for his guidance on how to best fix this bug and also for reviewing a number of patch attempts prior to this one.

* hb/kernel/too_greedy_disk_log/OTP-9764: Make sure disk_log does not write too much data
2011-12-04Make sure disk_log does not write too much dataHans Bolinder
While disk_log eagerly collects logged data for better performance, collecting too much data may choke the system and cause huge binaries to be written. (Reported by Klarna.) (Logging data faster than the speed disk_log can write to disk can still cause problems.)

2011-12-02Skip recv/send during tests for fallback platformsLukas Larsson
2011-12-02Remove header/trailer supportLukas Larsson
Since the API for headers/trailers seem to be very awkward to work with when using non-blocking io the feature is dropped for now. See unix_efile.c for more details.
2011-12-02Expand sendfile documentationLukas Larsson
2011-12-02Move sendfile api to file moduleLukas Larsson
Since sendfile could in theory be used to send to any type of file descriptor in *nix, it is a better fit to have it in file.
2011-12-01Preliminary work on header/trailerLukas Larsson
Have to figure out how to represent progress in header writing when using non-blocking, not sure how to do this.
2011-12-01Add tests for send/recv/sendfile interactionsLukas Larsson
Tests for when a gen_tcp:send/recv is ordered while a sendfile is in progress.
2011-12-01Remove tests for file_server sendfileLukas Larsson
2011-12-01sendfile caller now has to be the controlling_processLukas Larsson
This is needed because otherwise there could be scenarios when the efile driver blocks a fd and then crashes without the inet driver ever finding out. Now when the process crashes the port will close and we can cleanup in the inet driver.
2011-12-01Remove support for file_server, sendfile has to be rawLukas Larsson
Because the sending process has to be the controlling process of the tcp socket used to send data it is not possible to use the file_server
2011-12-01Implement ignorefd for TCPLukas Larsson
Ignore fd is a feature used by sendfile to temporarily remove all driver_select calls on that fd so that another driver can select on it. It also delays all actions which sends or receives data in that fd until in the fd is no longer ignored. Only the controlling_process should use the feature as it is otherwise possible that the ignore will never be cleaned up and hence create a memory leak in the driver. An ignored driver will not detect that an fd has been closed until it is unignored.
2011-12-01Implement sendfile when there are no async threadsLukas Larsson
When there are no async threads sendfile will use the ready_output select on the socket fd to know when to send data. The file_desc will also be put in the sending sendfile_state which buffers all other commands to that file until the sendfile is done.
2011-12-01Implement blocking calls for sendfileLukas Larsson
Move sendfile data to invoke data instead of file_descr. Remove usage of ready_output when doing a send. If told to send 0 bytes, file_sendfile now sends the entire file for linux.
