2018-10-03memory: ensure to check allocation resultsDaniel Gustafsson
The result of a memory allocation should always be checked, as we may run under memory pressure where even a small allocation can fail. This adds checking and error handling to a few cases where the allocation wasn't checked for success. In the ftp case, the freeing of the path variable is moved ahead of the allocation since there is little point in keeping it around across the strdup, and the separation makes for more readable code. In nwlib, the lock is aslo freed in the error path. Also bumps the copyright years on affected files.

2018-09-13sendf: Fix whitespace in infof/failf concatenationDaniel Gustafsson
Strings broken on multiple rows in the .c file need to have appropriate whitespace padding on either side of the concatenation point to render a correct amalgamated string. Fix by adding a space at the occurrences found. Closes #2986 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

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.

2018-05-16schannel: 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.
2018-04-18schannel: add support for CURLOPT_CAINFODan McNulty
- Move verify_certificate functionality in schannel.c into a new file called schannel_verify.c. Additionally, some structure defintions from schannel.c have been moved to schannel.h to allow them to be used in schannel_verify.c. - Make verify_certificate functionality for Schannel available on all versions of Windows instead of just Windows CE. verify_certificate will be invoked on Windows CE or when the user specifies CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER. - In verify_certificate, create a custom certificate chain engine that exclusively trusts the certificate store backed by the CURLOPT_CAINFO file. - doc updates of --cacert/CAINFO support for schannel - Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString when available. This implements a TODO in schannel.c to improve handling of multiple SANs in a certificate. In particular, all SANs will now be searched instead of just the first name. - Update tool_operate.c to not search for the curl-ca-bundle.crt file when using Schannel to maintain backward compatibility. Previously, any curl-ca-bundle.crt file found in that search would have been ignored by Schannel. But, with CAINFO support, the file found by that search would have been used as the certificate store and could cause issues for any users that have curl-ca-bundle.crt in the search path. - Update url.c to not set the build time CURL_CA_BUNDLE if the selected SSL backend is Schannel. We allow setting CA location for schannel only when explicitly specified by the user via CURLOPT_CAINFO / --cacert. - Add new test cases 3000 and 3001. These test cases check that the first and last SAN, respectively, matches the connection hostname. New test certificates have been added for these cases. For 3000, the certificate prefix is Server-localhost-firstSAN and for 3001, the certificate prefix is Server-localhost-secondSAN. - Remove TODO 15.2 (Add support for custom server certificate validation), this commit addresses it.
