2020-02-09smtp: Simplify the MAIL command and avoid a duplication of send stringsSteve Holme
This avoids the duplication of strings when the optional AUTH and SIZE parameters are required. It also assists with the modifications that are part of #4892. Closes #4903
2020-01-21smtp: Allow RCPT TO command to fail for some recipientsPavel Volgarev
Introduces CURLOPT_MAIL_RCPT_ALLLOWFAILS. Verified with the new tests 3002-3007 Closes #4816
2019-09-03smtp: check for and bail out on too short EHLO responseDaniel Stenberg
Otherwise, a three byte response would make the smtp_state_ehlo_resp() function misbehave. Credit to OSS-Fuzz Bug: https://crbug.com/oss-fuzz/16918 Assisted-by: Max Dymond Closes #4287
2019-07-30cleanup: remove the 'numsocks' argument used in many placesDaniel Stenberg
It was used (intended) to pass in the size of the 'socks' array that is also passed to these functions, but was rarely actually checked/used and the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries that should be used instead. Closes #4169
2019-06-05build: fix Codacy warningsMarcel Raad
Reduce variable scopes and remove redundant variable stores. Closes https://github.com/curl/curl/pull/3975
2019-05-16cleanup: remove FIXME and TODO commentsDaniel Stenberg
They serve very little purpose and mostly just add noise. Most of them have been around for a very long time. I read them all before removing or rephrasing them. Ref: #3876 Closes #3883
2019-04-11emailL Added reference to RFC8314 for implicit TLSSteve Holme
2019-04-04smtp: fix compiler warningRikard Falkeborn
- Fix clang string-plus-int warning. Clang 8 warns about adding a string to an int does not append to the string. Indeed it doesn't, but that was not the intention either. Use array indexing as suggested to silence the warning. There should be no functional changes. (In other words clang warns about "foo"+2 but not &"foo"[2] so use the latter.) smtp.c:1221:29: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int] eob = strdup(SMTP_EOB + 2); ~~~~~~~~~~~~~~~~^~~~ Closes https://github.com/curl/curl/pull/3729
2019-03-01urldata: simplify bytecountersDaniel Stenberg
- no need to have them protocol specific - no need to set pointers to them with the Curl_setup_transfer() call - make Curl_setup_transfer() operate on a transfer pointer, not connection - switch some counters from long to the more proper curl_off_t type Closes #3627
2019-02-04smtp: avoid risk of buffer overflow in strtolDaniel Gustafsson
If the incoming len 5, but the buffer does not have a termination after 5 bytes, the strtol() call may keep reading through the line buffer until is exceeds its boundary. Fix by ensuring that we are using a bounded read with a temporary buffer on the stack. Bug: https://curl.haxx.se/docs/CVE-2019-3823.html Reported-by: Brian Carpenter (Geeknik Labs) CVE-2019-3823
2018-12-17pingpong: ignore regular timeout in disconnect phaseDaniel Stenberg
The timeout set with CURLOPT_TIMEOUT is no longer used when disconnecting from one of the pingpong protocols (FTP, IMAP, SMTP, POP3). Reported-by: jasal82 on github Fixes #3264 Closes #3374
2018-09-22url: use the URL API internally as wellDaniel Stenberg
... to make it a truly unified URL parser. Closes #3017
2018-09-06CURLOPT_UPLOAD_BUFFERSIZE: set upload buffer sizeDaniel Stenberg
This is step 3 of #2888. Fixes #2888 Closes #2896
2018-07-09smtp: use the upload buffer size for scratch buffer mallocDaniel Stenberg
... not the read buffer size, as that can be set smaller and thus cause a buffer overflow! CVE-2018-0500 Reported-by: Peter Wu Bug: https://curl.haxx.se/docs/adv_2018-70a2.html
2018-06-11cppcheck: fix warningsMarian Klymov
- Get rid of variable that was generating false positive warning (unitialized) - Fix issues in tests - Reduce scope of several variables all over etc Closes #2631
2018-02-12smtp: fix processing of initial dot in dataPatrick Monnerat
RFC 5321 4.1.1.4 specifies the CRLF terminating the DATA command should be taken into account when chasing the <CRLF>.<CRLF> end marker. Thus a leading dot character in data is also subject to escaping. Tests 911 and test server are adapted to this situation. New tests 951 and 952 check proper handling of initial dot in data. Closes #2304
2018-01-15smtp/pop3/imap_get_message: decrease the data length too...Daniel Stenberg
Follow-up commit to 615edc1f73 which was incomplete. Assisted-by: Max Dymond Detected by OSS-fuzz Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=5206
2017-12-05sasl_getmesssage: make sure we have a long enough string to passDaniel Stenberg
For pop3/imap/smtp, added test 891 to somewhat verify the pop3 case. For this, I enhanced the pingpong test server to be able to send back responses with LF-only instead of always using CRLF. Closes #2150
2017-10-25time: rename Curl_tvnow to Curl_nowDaniel Stenberg
... since the 'tv' stood for timeval and this function does not return a timeval struct anymore. Also, cleaned up the Curl_timediff*() functions to avoid typecasts and clean up the descriptive comments. Closes #2011
2017-10-10smtp_done: free data before returning (on send failure)Daniel Stenberg
... as otherwise it could leak that memory. Detected by OSS-fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3600 Assisted-by: Max Dymond Closes #1977
2017-09-20smtp: fix memory leak in OOMDaniel Stenberg
Regression since ce0881edee Coverity CID 1418139 and CID 1418136 found it, but it was also seen in torture testing.
2017-09-02mime: new MIME API.Patrick Monnerat
Available in HTTP, SMTP and IMAP. Deprecates the FORM API. See CURLOPT_MIMEPOST. Lib code and associated documentation.
2017-06-30handler: refactor connection checkingMax Dymond
Add a new type of callback to Curl_handler which performs checks on the connection. Alter RTSP so that it uses this callback to do its own check on connection health.
2017-06-15http-proxy: only attempt FTP over HTTP proxyDaniel Stenberg
... all other non-HTTP protocol schemes are now defaulting to "tunnel trough" mode if a HTTP proxy is specified. In reality there are no HTTP proxies out there that allow those other schemes. Assisted-by: Ray Satiro, Michael Kaufmann Closes #1505
2017-05-01buffer: use data->set.buffer_size instead of BUFSIZEDaniel Stenberg
... to properly use the dynamically set buffer size!
2017-02-10URL: only accept ";options" in SMTP/POP3/IMAP URL schemesDaniel Stenberg
Fixes #1252
2017-01-12smtp: Fix STARTTLS denied error messageJay Satiro
- Format the numeric denial code as an integer instead of a character.
2016-11-24checksrc: white space edits to comply to stricter checksrcDaniel Stenberg
2016-11-24checksrc: code style: use 'char *name' styleDaniel Stenberg
2016-10-31strcasecompare: all case insensitive string compares ignore locale nowDaniel Stenberg
We had some confusions on when each function was used. We should not act differently on different locales anyway.
2016-10-31strcasecompare: is the new name for strequal()Daniel Stenberg
... to make it less likely that we forget that the function actually does case insentive compares. Also replaced several invokes of the function with a plain strcmp when case sensitivity is not an issue (like comparing with "-").
2016-09-07errors: new alias CURLE_WEIRD_SERVER_REPLY (8)Jay Satiro
Since we're using CURLE_FTP_WEIRD_SERVER_REPLY in imap, pop3 and smtp as more of a generic "failed to parse" introduce an alias without FTP in the name. Closes https://github.com/curl/curl/pull/975
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-05-23smtp: minor ident (white space) fixesDaniel Stenberg
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743
2016-03-30multi: turn Curl_done into file local multi_doneDaniel Stenberg
... as it now is used by multi.c only.
2016-03-19ftp/imap/pop3/smtp: Fixed compilation warning when /Wall enabledSteve Holme
warning C4706: assignment within conditional expression
2016-03-08imap/pop3/smtp: Fixed connections upgraded with TLS are not reusedSteve Holme
Regression since commit 710f14edba. Bug: https://github.com/curl/curl/issues/422 Reported-by: Justin Ehlert
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2015-11-24Revert "cleanup: general removal of TODO (and similar) comments"Daniel Stenberg
This reverts commit 64e959ffe37c436503f9fed1ce2d6ee6ae50bd9a. Feedback-by: Dan Fandrich URL: http://curl.haxx.se/mail/lib-2015-11/0062.html
2015-11-13cleanup: general removal of TODO (and similar) commentsDaniel Stenberg
They tend to never get updated anyway so they're frequently inaccurate and we never go back to revisit them anyway. We document issues to work on properly in KNOWN_BUGS and TODO instead.
2015-03-16free: instead of Curl_safefree()Daniel Stenberg
Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2015-01-27sasl: implement EXTERNAL authentication mechanism.Patrick Monnerat
Its use is only enabled by explicit requirement in URL (;AUTH=EXTERNAL) and by not setting the password.
2015-01-20SASL: common state engine for imap/pop3/smtpPatrick Monnerat
2015-01-20SASL: common URL option and auth capabilities decoders for all protocolsPatrick Monnerat
2015-01-20IMAP/POP3/SMTP: use a per-connection sub-structure for SASL parameters.Patrick Monnerat
2014-12-16IPV6: address scope != scope idPatrick Monnerat
There was a confusion between these: this commit tries to disambiguate them. - Scope can be computed from the address itself. - Scope id is scope dependent: it is currently defined as 1-based local interface index for link-local scoped addresses, and as a site index(?) for (obsolete) site-local addresses. Linux only supports it for link-local addresses. The URL parser properly parses a scope id as an interface index, but stores it in a field named "scope": confusion. The field has been renamed into "scope_id". Curl_if2ip() used the scope id as it was a scope. This caused failures to bind to an interface. Scope is now computed from the addresses and Curl_if2ip() matches them. If redundantly specified in the URL, scope id is check for mismatch with the interface index. This commit should fix SF bug #1451.
