2012-03-31Revert "mk-ca-bundle.pl: use LWP::UserAgent for https"Daniel Stenberg
This reverts commit 9f0e1689f169b83b8fbdae23e0024cc57dcbc770. It turned out that "improvement" instead made the fetching of the certificates unreliable Bug: http://curl.haxx.se/mail/lib-2012-03/0238.html Reported by: Tim Heckman
2012-03-31pop3: Added support for additional pop3 commandsSteve Holme
This feature allows the user to specify and use additional POP3 commands such as UIDL and DELE via libcurl's CURLOPT_CUSTOMREQUEST or curl's -X command line option.
2012-03-25ssh.c: code cleanup, Curl_safefree() already nullifies pointerYang Tse
2012-03-25fix some compiler warningsYang Tse
2012-03-25pop3.c: Corrected problem with state() introduced in 01690ed2bce5Steve Holme
2012-03-25pop.c: Small code tidy upSteve Holme
2012-03-25pop3: Removed the need for the single message LIST command handlerSteve Holme
Simplified the code to remove the need for a separate "LIST <msg id>" command handler and state machine and instead use the LIST command handler for both operations.
2012-03-24pop3.c: Code policing and tidy upSteve Holme
Corrected character and line spacing and re-ordered list and retr functions based on the order of their state machines.
2012-03-24email: Moved server greeting responses into separate functionsSteve Holme
Moved the server greeting response handling code from the statemach_act functions to separate response functions. This makes the code simpler to follow and provides consistency with the other responses that are handled here.
2012-03-24pop3.c: Fixed body data being written when CURLOPT_NOBODY is specifiedSteve Holme
Body data would be forwarded to the client application in both the RETR and LIST commands even if CURLOPT_NOBODY was specified.
2012-03-22http_proxy.h: fix builds with proxy or http disabledYang Tse
2012-03-22parsedate.c: fix a numeric overflowYang Tse
2012-03-22cookies: strip the numerical ipv6 host properlyAndrei Cipu
The commit e650dbde86d4 that stripped off [brackets] from ipv6-only host headers for the sake of cookie parsing wrongly incremented the host pointer which would cause a bad free() call later on.
2012-03-22fix several compiler warningsYang Tse
2012-03-22CONNECT: fix multi interface regressionDaniel Stenberg
The refactoring of HTTP CONNECT handling in commit 41b0237834232 that made it protocol independent broke it for the multi interface. This fix now introduce a better state handling and moved some logic to the http_proxy.c source file. Reported by: Yang Tse Bug: http://curl.haxx.se/mail/lib-2012-03/0162.html
2012-03-20fix several compiler warningsYang Tse

2012-03-16fix some compiler warningsYang Tse
2012-03-13resolve with c-ares: don't resolve IPv6 when not workingMaxim Prohorov
If the Curl_ipv6works() function says no, there is no reason to try AAAA names even if libcurl was built with IPv6 support enabled. Bug: http://curl.haxx.se/mail/lib-2012-03/0045.html
2012-03-10smtp.c: Changed the curl error code for EHLO and HELO responsesSteve Holme
Changed the returned curl error codes for EHLO and HELO responses from CURLE_LOGIN_DENIED to CURLE_REMOTE_ACCESS_DENIED as a negative response from these commands represents no service as opposed to a login error.
2012-03-10Curl_http: strip off [brackets] from ipv6-only host headersAndrei Cipu
Since the host name is passed in to the cookie engine it will not work correctly if the brackets are left in the name. Bug:http://curl.haxx.se/mail/lib-2012-03/0036.html
2012-03-10mk-ca-bundle.pl: use LWP::UserAgent with proper https verify behavior.John Joseph Bachir
An alternative would be: 1. specify HTTPS_CA_DIR and/or HTTPS_CA_FILE 2. ensure that Net::SSL is being used, and IO::Socket::SSL is NOT being used This question and answer explain: http://stackoverflow.com/questions/74358/
2012-03-10access the CA source file using HTTPSJohn Joseph Bachir
2012-03-09includes: remove inclusion of unused file http_proxy.hDaniel Stenberg
2012-03-08CONNECT: made generically not per-protocolDaniel Stenberg
Curl_protocol_connect() now does the tunneling through the HTTP proxy if requested instead of letting each protocol specific connection function do it.
2012-03-08ssh_connect: tunnel through HTTP proxy if requestedDaniel Stenberg
2012-03-08LWIP: don't consider HAVE_ERRNO_H to be winsockDaniel Stenberg
The check for Winsock definition was a bit too broad Bug: http://curl.haxx.se/mail/lib-2012-03/0046.html
2012-02-24CONNECT: fix ipv6 address in the Request-LineDaniel Stenberg
Commit 466150bc64d fixed the Host: header with CONNECT, but I then forgot the preceeding request-line. Now this too uses [brackets] properly if a ipv6 numerical address was given. Bug: http://curl.haxx.se/bug/view.cgi?id=3493129 Reported by: "Blacat"
2012-02-23SMTP: Added support for returning SMTP response codesSteve Holme
Set the conn->data->info.httpcode variable in smtp_statemach_act() to allow Curl_getinfo() to return the SMTP response code via the CURLINFO_RESPONSE_CODE action.
2012-02-21smtp.c: Fixed an issue with writing postdataSteve Holme
Fixed a problem in smtp_done() when writing out the postdata as Curl_write() would periodically return zero bytes written.
2012-02-19pop3.c: Fixed drop of final CRLF in EOB checkingSteve Holme
Curl_pop3_write() would drop the final CRLF of a message as it was considered part of the EOB as opposed to part of the message. Whilst the EOB sequence needs to be searched for by the function only the final 3 characters should be removed as per RFC-1939 section 3. Reported by: Rich Gray Bug: http://curl.haxx.se/mail/lib-2012-02/0051.html
2012-02-17smtp.c: Fixed an issue with the EOB checkingSteve Holme
Curl_smtp_escape_eob() would leave off final CRLFs from emails ending in multiple blank lines additionally leaving the smtpc->eob variable with the character count in, which would cause problems for additional emails when sent through multiple calls to curl_easy_perform() after a CURLOPT_CONNECT_ONLY.
2012-02-16SMTP: Code policing and tidy upSteve Holme
2012-02-15smtp.c: Fixed use of angled brackets in AUTH parameter.Steve Holme
Fixed the use of angled brackets "<>" in the optional AUTH parameter as per RFC-2554 section 5. The address should not include them but an empty address should be replaced by them.
2012-02-14smtp_mail: Added support to MAIL FROM for the optional AUTH parameterSteve Holme
Added a new CURLOPT_MAIL_AUTH option that allows the calling program to set the optional AUTH parameter in the MAIL FROM command. When this option is specified and an authentication mechanism is used to communicate with the mail server then the AUTH parameter will be included in the MAIL FROM command. This is particularly useful when the calling program is acting as a relay in a trusted environment and performing server to server communication, as it allows the relaying server to specify the address of the mailbox that was used to authenticate and send the original email.
2012-02-14cyassl: update to CyaSSL 2.0.x APItoddouska
Modify configure.ac to test for new CyaSSL Init function and remove default install path to system. Change to CyaSSL OpenSSL header and proper Init in code as well. Note that this no longer detects or works with CyaSSL before v2
2012-02-14SMTP: Fixed error when using CURLOPT_CONNECT_ONLYSteve Holme
Fixed incorrect behavior in smtp_done() which would cause the end of block data to be sent to the SMTP server if libcurl was operating in connect only mode. This would cause the server to return an error as data would not be expected which in turn caused libcurl to return CURLE_RECV_ERROR.
2012-02-10parse_proxy: simply memory handlingDaniel Stenberg
... by making sure that the string is always freed after the invoke as parse_proxy will always copy the data and this way there's a single free() instead of multiple ones.
2012-02-10parse_proxy: bail out on zero-length proxy names!Daniel Stenberg
The proxy parser function strips off trailing slashes off the proxy name which could lead to a mistaken zero length proxy name which would be treated as no proxy at all by subsequent functions! This is now detected and an error is returned. Verified by the new test 1329. Reported by: Chandrakant Bagul Bug: http://curl.haxx.se/mail/lib-2012-02/0000.html
2012-02-09nss: add support for the CURLSSLOPT_ALLOW_BEAST optionKamil Dudka
... and fix some typos from the 62d15f1 commit.
2012-02-09CURLOPT_SSL_OPTIONS: addedDaniel Stenberg
Allow an appliction to set libcurl specific SSL options. The first and only options supported right now is CURLSSLOPT_ALLOW_BEAST. It will make libcurl to disable any work-arounds the underlying SSL library may have to address a known security flaw in the SSL3 and TLS1.0 protocol versions. This is a reaction to us unconditionally removing that behavior after this security advisory: http://curl.haxx.se/docs/adv_20120124B.html ... it did however cause a lot of programs to fail because of old servers not liking this work-around. Now programs can opt to decrease the security in order to interoperate with old servers better.
2012-02-09add library support for tuning TCP_KEEPALIVEDave Reisner
This adds three new options to control the behavior of TCP keepalives: - CURLOPT_TCP_KEEPALIVE: enable/disable probes - CURLOPT_TCP_KEEPIDLE: idle time before sending first probe - CURLOPT_TCP_KEEPINTVL: delay between successive probes While not all operating systems support the TCP_KEEPIDLE and TCP_KEEPINTVL knobs, the library will still allow these options to be set by clients, silently ignoring the values.
2012-02-07curl_easy_reset: reset the referer stringDaniel Stenberg
When CURLOPT_REFERER has been used, curl_easy_reset() did not properly clear it. Verified with the new test 598 Bug: http://curl.haxx.se/bug/view.cgi?id=3481551 Reported by: Michael Day
2012-01-31CONNECT: send correct Host: with IPv6 numerical addressDaniel Stenberg
When the target host was given as a IPv6 numerical address, it was not properly put within square brackets for the Host: header in the CONNECT request. The "normal" request did fine. Reported by: "zooloo" Bug: http://curl.haxx.se/bug/view.cgi?id=3482093
2012-01-28more resilient connection times among IP addressesPierre Ynard
When connecting to a domain with multiple IP addresses, allow different, decreasing connection timeout values. This should guarantee some connections attempts with sufficiently long timeouts, while still providing fallback.
2012-01-28remove write-only variablePierre Ynard
2012-01-24gnutls: enforced use of SSLv3Daniel Stenberg
With advice from Nikos Mavrogiannopoulos, changed the priority string to add "actual priorities" and favour ARCFOUR. This makes libcurl work better when enforcing SSLv3 with GnuTLS. Both in the sense that the libmicrohttpd test is now working again but also that it mitigates a weakness in the older SSL/TLS protocols. Bug: http://curl.haxx.se/mail/lib-2012-01/0225.html Reported by: Christian Grothoff
2012-01-24URL sanitize: reject URLs containing bad dataDaniel Stenberg
Protocols (IMAP, POP3 and SMTP) that use the path part of a URL in a decoded manner now use the new Curl_urldecode() function to reject URLs with embedded control codes (anything that is or decodes to a byte value less than 32). URLs containing such codes could easily otherwise be used to do harm and allow users to do unintended actions with otherwise innocent tools and applications. Like for example using a URL like pop3://pop3.example.com/1%0d%0aDELE%201 when the app wants a URL to get a mail and instead this would delete one. This flaw is considered a security vulnerability: CVE-2012-0036 Security advisory at: http://curl.haxx.se/docs/adv_20120124.html Reported by: Dan Fandrich
2012-01-24OpenSSL: don't disable security work-aroundDaniel Stenberg
OpenSSL added a work-around for a SSL 3.0/TLS 1.0 CBC vulnerability (http://www.openssl.org/~bodo/tls-cbc.txt). In 0.9.6e they added a bit to SSL_OP_ALL that _disables_ that work-around despite the fact that SSL_OP_ALL is documented to do "rather harmless" workarounds. The libcurl code uses the SSL_OP_ALL define and thus logically always disables the OpenSSL fix. In order to keep the secure work-around workding, the SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit must not be set and this change makes sure of this. Reported by: product-security at Apple
