2019-02-19x509asn1: cleanup and unify code layoutDaniel Stenberg
- rename 'n' to buflen in functions, and use size_t for them. Don't pass in negative buffer lengths. - move most function comments to above the function starts like we use to - remove several unnecessary typecasts (especially of NULL) Reviewed-by: Patrick Monnerat Closes #3582

2019-02-19http: make adding a blank header thread-safeDaniel Stenberg
Previously the function would edit the provided header in-place when a semicolon is used to signify an empty header. This made it impossible to use the same set of custom headers in multiple threads simultaneously. This approach now makes a local copy when it needs to edit the string.

2019-02-18x509asn1: replace single char with an arrayPatrick Monnerat
Although safe in this context, using a single char as an array may cause invalid accesses to adjacent memory locations. Detected by Coverity.
2019-02-18examples/http2-serverpush: add some sensible error checksDaniel Stenberg
To avoid NULL pointer dereferences etc in the case of problems. Closes #3580
2019-02-18easy: fix win32 init to work without CURL_GLOBAL_WIN32Jay Satiro
- Change the behavior of win32_init so that the required initialization procedures are not affected by CURL_GLOBAL_WIN32 flag. libcurl via curl_global_init supports initializing for win32 with an optional flag CURL_GLOBAL_WIN32, which if omitted was meant to stop Winsock initialization. It did so internally by skipping win32_init() when that flag was set. Since then win32_init() has been expanded to include required initialization routines that are separate from Winsock and therefore must be called in all cases. This commit fixes it so that CURL_GLOBAL_WIN32 only controls the optional win32 initialization (which is Winsock initialization, according to our doc). The only users affected by this change are those that don't pass CURL_GLOBAL_WIN32 to curl_global_init. For them this commit removes the risk of a potential crash.

2019-02-17cookie: Add support for cookie prefixesDaniel Gustafsson
The draft-ietf-httpbis-rfc6265bis-02 draft, specify a set of prefixes and how they should affect cookie initialization, which has been adopted by the major browsers. This adds support for the two prefixes defined, __Host- and __Secure, and updates the testcase with the supplied examples from the draft. Closes #3554 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2019-02-16mbedtls: release sessionid resources on errorDaniel Gustafsson
If mbedtls_ssl_get_session() fails, it may still have allocated memory that needs to be freed to avoid leaking. Call the library API function to release session resources on this errorpath as well as on Curl_ssl_addsessionid() errors.

I missed to check this in with commit 71786c0505926aaf7e9b2477b2fb7ee16a915ec6, which only disabled the test. This fixes the actual linker error. Closes https://github.com/curl/curl/pull/3568

2019-02-14connection_check: restore original conn->data after the checkJay Satiro
- Save the original conn->data before it's changed to the specified data transfer for the connection check and then restore it afterwards. This is a follow-up to 38d8e1b 2019-02-11. History: It was discovered a month ago that before checking whether to extract a dead connection that that connection should be associated with a "live" transfer for the check (ie original conn->data ignored and set to the passed in data). A fix was landed in 54b201b which did that and also cleared conn->data after the check. The original conn->data was not restored, so presumably it was thought that a valid conn->data was no longer needed. Several days later it was discovered that a valid conn->data was needed after the check and follow-up fix was landed in bbae24c which partially reverted the original fix and attempted to limit the scope of when conn->data was changed to only when pruning dead connections. In that case conn->data was not cleared and the original conn->data not restored. A month later it was discovered that the original fix was somewhat correct; a "live" transfer is needed for the check in all cases because original conn->data could be null which could cause a bad deref at arbitrary points in the check. A fix was landed in 38d8e1b which expanded the scope to all cases. conn->data was not cleared and the original conn->data not restored. A day later it was discovered that not restoring the original conn->data may lead to busy loops in applications that use the event interface, and given this observation it's a pretty safe assumption that there is some code path that still needs the original conn->data. This commit is the follow-up fix for that, it restores the original conn->data after the connection check.

2019-02-14transfer.c: do not compute length of undefined hex buffer.Patrick Monnerat
On non-ascii platforms, the chunked hex header was measured for char code conversion length, even for chunked trailers that do not have an hex header. In addition, the efective length is already known: use it. Since the hex length can be zero, only convert if needed. Reported by valgrind.
