2018-05-22schannel: make CAinfo parsing resilient to CR/LFJohannes Schindelin
OpenSSL has supported --cacert for ages, always accepting LF-only line endings ("Unix line endings") as well as CR/LF line endings ("Windows line endings"). When we introduced support for --cacert also with Secure Channel (or in cURL speak: "WinSSL"), we did not take care to support CR/LF line endings, too, even if we are much more likely to receive input in that form when using Windows. Let's fix that. Happily, CryptQueryObject(), the function we use to parse the ca-bundle, accepts CR/LF input already, and the trailing LF before the END CERTIFICATE marker catches naturally any CR/LF line ending, too. So all we need to care about is the BEGIN CERTIFICATE marker. We do not actually need to verify here that the line ending is CR/LF. Just checking for a CR or an LF is really plenty enough.

2018-05-21checksrc: make sure sizeof() is used *with* parenthesesDaniel Stenberg
... and unify the source code to adhere. Closes #2563
2018-05-18curl_fnmatch: only allow two asterisks for matchingDaniel Stenberg
The previous limit of 5 can still end up in situation that takes a very long time and consumes a lot of CPU. If there is still a rare use case for this, a user can provide their own fnmatch callback for a version that allows a larger set of wildcards. This commit was triggered by yet another OSS-Fuzz timeout due to this. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8369 Closes #2587
2018-05-18docs: mention HAproxy protocol "version 1"Aleks
...as there's also a version 2. Closes #2579
2018-05-17getinfo: add microsecond precise timers for various intervalsPhilip Prindeville
Provide a set of new timers that return the time intervals using integer number of microseconds instead of floats. The new info names are as following: CURLINFO_APPCONNECT_TIME_T CURLINFO_CONNECT_TIME_T CURLINFO_NAMELOOKUP_TIME_T CURLINFO_PRETRANSFER_TIME_T CURLINFO_REDIRECT_TIME_T CURLINFO_STARTTRANSFER_TIME_T CURLINFO_TOTAL_TIME_T Closes #2495
2018-05-17openssl: acknowledge --tls-max for default version tooDaniel Stenberg
... previously it only used the max setting if a TLS version was also explicitly asked for. Reported-by: byte_bucket Fixes #2571 Closes #2572
2018-05-16schannel_verify: fix build for non-schannelDaniel Stenberg
2018-05-16rand: fix typoJay Satiro
2018-05-16schannel: disable manual verify if APIs not availableJay Satiro
.. because original MinGW and old compilers do not have the Windows API definitions needed to support manual verification.
2018-05-16schannel: disable client cert option if APIs not availableArchangel_SDY
Original MinGW targets Windows 2000 by default, which lacks some APIs and definitions for this feature. Disable it if these APIs are not available. Closes https://github.com/curl/curl/pull/2522

When there's an upload in progress, make sure to wait for the socket to become writable. Detected-by: steini2000 on github Bug: #2520 Closes #2567
2018-05-14pingpong: fix response cache memcpy overflowDaniel Stenberg
Response data for a handle with a large buffer might be cached and then used with the "closure" handle when it has a smaller buffer and then the larger cache will be copied and overflow the new smaller heap based buffer. Reported-by: Dario Weisser CVE: CVE-2018-1000300 Bug: https://curl.haxx.se/docs/adv_2018-82c2.html
2018-05-14http: restore buffer pointer when bad response-line is parsedDaniel Stenberg

2018-05-13cookies: do not take cookie name as a parameterPatrick Monnerat
RFC 6265 section 4.2.1 does not set restrictions on cookie names. This is a follow-up to commit 7f7fcd0. Also explicitly check proper syntax of cookie name/value pair. New test 1155 checks that cookie names are not reserved words. Reported-By: anshnd at github Fixes #2564 Closes #2566

2018-05-11setup_transfer: deal with both sockets being -1Daniel Stenberg
Detected by Coverity; CID 1435559. Follow-up to f8d608f38d00. It would index the array with -1 if neither index was a socket.
2018-05-10openssl: change FILE ops to BIO opsSunny Purushe
To make builds with VS2015 work. Recent changes in VS2015 _IOB_ENTRIES handling is causing problems. This fix changes the OpenSSL backend code to use BIO functions instead of FILE I/O functions to circumvent those problems. Closes #2512
2018-05-04vtls: fix missing commasDaniel Stenberg
follow-up to e66cca046cef
2018-05-04vtls: use unified "supports" bitfield member in backendsDaniel Stenberg
... instead of previous separate struct fields, to make it easier to extend and change individual backends without having to modify them all. closes #2547
2018-05-04transfer: don't unset writesockfd on setup of multiplexed connsDaniel Stenberg
Curl_setup_transfer() can be called to setup a new individual transfer over a multiplexed connection so it shouldn't unset writesockfd. Bug: #2520 Closes #2549
2018-05-04http: don't set the "rewind" flag when not uploading anythingDaniel Stenberg
It triggers an assert. Detected by OSS-Fuzz Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8144 Closes #2546
2018-05-03ssh-libssh.c: fix left shift compiler warningDaniel Stenberg
ssh-libssh.c:2429:21: warning: result of '1 << 31' requires 33 bits to represent, but 'int' only has 32 bits [-Wshift-overflow=] 'len' will never be that big anyway so I converted the run-time check to a regular assert.
2018-05-03URL: fix ASCII dependency in strcpy_url and strlen_urlStephan Mühlstrasser
Commit 3c630f9b0af097663a64e5c875c580aa9808a92b partially reverted the changes from commit dd7521bcc1b7a6fcb53c31f9bd1192fcc884bd56 because of the problem that strcpy_url() was modified unilaterally without also modifying strlen_url(). As a consequence strcpy_url() was again depending on ASCII encoding. This change fixes strlen_url() and strcpy_url() in parallel to use a common host-encoding independent criterion for deciding whether an URL character must be %-escaped. Closes #2535
2018-05-02vtls: don't define MD5_DIGEST_LENGTH for wolfsslDaniel Stenberg
... as it defines it (too)

2018-04-27cookies: remove unused macroDaniel Gustafsson
Commit 2bc230de63 made the macro MAX_COOKIE_LINE_TXT become unused, so remove as it's not part of the published API. Closes https://github.com/curl/curl/pull/2537
2018-04-27checksrc: force indentation of lines after an elseDaniel Gustafsson
This extends the INDENTATION case to also handle 'else' statements and require proper indentation on the following line. Also fixes the offending cases found in the codebase. Closes #2532
2018-04-26http2: fix null pointer dereference in http2_connisdeadDaniel Stenberg
This function can get called on a connection that isn't setup enough to have the 'recv_underlying' function pointer initialized so it would try to call the NULL pointer. Reported-by: Dario Weisser Follow-up to db1b2c7fe9b093f8 (never shipped in a release) Closes #2536
2018-04-26http2: get rid of another strstr()Daniel Stenberg
Follow-up to 1514c44655e12e: replace another strstr() call done on a buffer that might not be zero terminated - with a memchr() call, even if we know the substring will be found.

2018-04-26cyassl: adapt to libraries without TLS 1.0 support built-inDaniel Stenberg
WolfSSL doesn't enable it by default anymore
2018-04-25cookies: ensure that we have cookies before writing jarDaniel Gustafsson
The jar should be written iff there are cookies, so ensure that we still have cookies after expiration to avoid creating an empty file. Closes #2529
2018-04-25strcpy_url: only %-encode values >= 0x80Daniel Stenberg

2018-04-24ctype: restore character classification for non-ASCII platformsStephan Mühlstrasser
With commit 4272a0b0fc49a1ac0ceab5c4a365c9f6ab8bf8e2 curl-speficic character classification macros and functions were introduced in curl_ctype.[ch] to avoid dependencies on the locale. This broke curl on non-ASCII, e.g. EBCDIC platforms. This change restores the previous set of character classification macros when CURL_DOES_CONVERSIONS is defined. Closes #2494

Closes #2499
2018-04-23http2: convert an assert to run-time checkDaniel Stenberg
Fuzzing has proven we can reach code in on_frame_recv with status_code not having been set, so let's detect that in run-time (instead of with assert) and error error accordingly. (This should no longer happen with the latest nghttp2) Detected by OSS-Fuzz Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7903 Closes #2514
2018-04-23schannel: fix build error on targets <= XPArchangel_SDY
- Use CRYPT_STRING_HEX instead of CRYPT_STRING_HEXRAW since XP doesn't support the latter. Ref: https://github.com/curl/curl/pull/2376#issuecomment-382153668 Closes https://github.com/curl/curl/pull/2504
2018-04-23Revert "ftplistparser: keep state between invokes"Daniel Stenberg
This reverts commit 8fb78f9ddc6d858d630600059b8ad84a80892fd9. Unfortunately this fix introduces memory leaks I've not been able to fix in several days. Reverting this for now to get the leaks fixed.
