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. The comment isn't the most important part of our code documentation but consistency has an intrinsic value in itself. This adds header guard comments to the files that were lacking it.

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.

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.

2018-10-01CMake: Improve config installationRuslan Baratov
Use 'GNUInstallDirs' standard module to set destinations of installed files. Use uppercase "CURL" names instead of lowercase "curl" to match standard 'FindCURL.cmake' CMake module: * https://cmake.org/cmake/help/latest/module/FindCURL.html Meaning: * Install 'CURLConfig.cmake' instead of 'curl-config.cmake' * User should call 'find_package(CURL)' instead of 'find_package(curl)' Use 'configure_package_config_file' function to generate 'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template file smaller and handle components better. E.g. current configuration report no error if user specified unknown components (note: new configuration expects no components, report error if user will try to specify any).
