2018-11-03infof: clearly indicate truncationDaniel Gustafsson
The internal buffer in infof() is limited to 2048 bytes of payload plus an additional byte for NULL termination. Servers with very long error messages can however cause truncation of the string, which currently isn't very clear, and leads to badly formatted output. This appends a "...\n" (or just "..." in case the format didn't with a newline char) marker to the end of the string to clearly show that it has been truncated. Also include a unittest covering infof() to try and catch any bugs introduced in this quite important function.

2018-11-03url: a short host name + port is not a schemeDaniel Stenberg
The function identifying a leading "scheme" part of the URL considered a few letters ending with a colon to be a scheme, making something like "short:80" to become an unknown scheme instead of a short host name and a port number. Extended test 1560 to verify. Reported-by: Hagai Auro Fixes #3220 Closes #3223
2018-11-03URL: fix IPv6 numeral address parserDaniel Stenberg

2018-11-02mprintf: avoid unsigned integer overflow warningTim Rühsen
The overflow has no real world impact. Just avoid it for "best practice". Code change suggested by "The Infinnovation Team" and Daniel Stenberg. Closes #3184
2018-11-02Curl_follow: accept non-supported schemes for "fake" redirectsDaniel Stenberg
When not actually following the redirect and the target URL is only stored for later retrieval, curl always accepted "non-supported" schemes. This was a regression from 46e164069d1a5230. Reported-by: Brad King Fixes #3210 Closes #3215

2018-11-01schannel: use Curl_ prefix for global private symbolsDaniel Stenberg
Curl_verify_certificate() must use the Curl_ prefix since it is globally available in the lib and otherwise steps outside of our namespace! Closes #3201
2018-10-30vtls: add MesaLink to curl_sslbackend enumDaniel Gustafsson
MesaLink support was added in commit 57348eb97d1b8fc3742e02c but the backend was never added to the curl_sslbackend enum in curl/curl.h. This adds the new backend to the enum and updates the relevant docs. Closes #3195 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

2018-10-27openssl: output the correct cipher list on TLS 1.3 errorDaniel Stenberg

2018-10-26ssh: free the session on init failuresDaniel Gustafsson
Ensure to clear the session object in case the libssh2 initialization fails. It could be argued that the libssh2 error function should be called to get a proper error message in this case. But since the only error path in libssh2_knownhost_init() is memory a allocation failure it's safest to avoid since the libssh2 error handling allocates memory.

2018-10-23headers: end all headers with guard commentDaniel Gustafsson
Most headerfiles end with a /* <headerguard> */ comment, but it was missing from some.

2018-10-16x509asn1: Fix SAN IP address verificationMatthew Whitehead
For IP addresses in the subject alternative name field, the length of the IP address (and hence the number of bytes to perform a memcmp on) is incorrectly calculated to be zero. The code previously subtracted q from name.end. where in a successful case q = name.end and therefore addrlen equalled 0. The change modifies the code to subtract name.beg from name.end to calculate the length correctly. The issue only affects libcurl with GSKit SSL, not other SSL backends. The issue is not a security issue as IP verification would always fail. Fixes #3102 Closes #3141

2018-10-07gskit: make sure to terminate version stringDaniel Gustafsson
In case a very small buffer was passed to the version function, it could result in the buffer not being NULL-terminated since strncpy() doesn't guarantee a terminator on an overflowed buffer. Rather than adding code to terminate (and handle zero-sized buffers), move to using snprintf() instead like all the other vtls backends.

2018-10-05checksrc: handle zero scoped ignore commandsDaniel Gustafsson
If a !checksrc! disable command specified to ignore zero errors, it was still added to the ignore block even though nothing was ignored. While there were no blocks ignored that shouldn't be ignored, the processing ended with with a warning: <filename>:<line>:<col>: warning: Unused ignore: LONGLINE (UNUSEDIGNORE) /* !checksrc! disable LONGLINE 0 */ ^ Fix by instead treating a zero ignore as a a badcommand and throw a warning for that one.

2018-10-05checksrc: enable strict mode and warningsDaniel Gustafsson
Enable strict and warnings mode for checksrc to ensure we aren't missing anything due to bugs in the checking code. This uncovered a few things which are all fixed in this commit: * several variables were used uninitialized * several variables were not defined in the correct scope * the whitelist filehandle was read even if the file didn't exist * the enable_warn() call when a disable counter had expired was passing incorrect variables, but since the checkwarn() call is unlikely to hit (the counter is only decremented to zero on actual ignores) it didn't manifest a problem.
