2020-02-28smtp: overwriting 'from' leaks memoryDaniel Stenberg
Detected by Coverity. CID 1418139. Also, make sure to return error if the new 'from' allocation fails. Closes #4997
2020-02-27smtp: fix memory leak on exit pathDaniel Stenberg
Detected by Coverity. CID 1418139. "leaked_storage: Variable 'from' going out of scope leaks the storage it points to" Closes #4990
2020-02-27Curl_is_ASCII_name: handle a NULL argumentDaniel Stenberg
Make the function tolerate a NULL pointer input to avoid dereferencing that pointer. Follow-up to efce3ea5a85126d Detected by OSS-Fuzz Reviewed-By: Steve Holme Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=20907 Fixes #4985 Closes #4986
2020-02-26smtp: Tidy up, following recent changes, to maintain the coding styleSteve Holme
Closes #4892
2020-02-26smtp: Support the SMTPUTF8 extension for the EXPN commandSteve Holme
Simply notify the server we support the SMTPUTF8 extension if it does.
2020-02-26smtp: Support the SMTPUTF8 extension in the VRFY commandSteve Holme
2020-02-26smtp: Support the SMTPUTF8 extension in the RCPT TO commandSteve Holme
Note: The RCPT TO command isn't required to advertise to the server that it contains UTF-8 characters, instead the server is told that a mail may contain UTF-8 in any envelope command via the MAIL command.
2020-02-26smtp: Support the SMTPUTF8 extension in the MAIL commandSteve Holme
Support the SMTPUTF8 extension when sending mailbox information in the MAIL command (FROM and AUTH parameters). Non-ASCII domain names will be ACE encoded, if IDN is supported, whilst non-ASCII characters in the local address part are passed to the server. Reported-by: ygthien on github Fixes #4828
2020-02-26smtp: Detect server support for the UTF-8 extension as defined in RFC-6531Steve Holme
2020-02-26smtp: Support UTF-8 based host names in the VRFY commandSteve Holme
2020-02-26smtp: Support UTF-8 based host names in the RCPT TO commandSteve Holme
2020-02-26smtp: Support UTF-8 based host names in the MAIL commandSteve Holme
Non-ASCII host names will be ACE encoded if IDN is supported.
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
