This is a companion patch to cbea2fd2c (NTLM: force the connection to
HTTP/1.1, 2018-12-06): with NTLM, we can switch to HTTP/1.1
preemptively. However, with other (Negotiate) authentication it is not
clear to this developer whether there is a way to make it work with
HTTP/2, so let's try HTTP/2 first and fall back in case we encounter the
error HTTP_1_1_REQUIRED.
Note: we will still keep the NTLM workaround, as it avoids an extra
round trip.
Daniel Stenberg helped a lot with this patch, in particular by
suggesting to introduce the Curl_h2_http_1_1_error() function.

Closes #3347

Since v7.62.0, cURL tries to use HTTP/2 whenever the server announces
the capability. However, NTLM authentication only works with HTTP/1.1,
and will likely remain in that boat (for details, see
https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-10/http2-on-iis#when-is-http2-not-supported).
When we just found out that we want to use NTLM, and when the current
connection runs in HTTP/2 mode, let's force the connection to be closed
and to be re-opened using HTTP/1.1.
Fixes https://github.com/curl/curl/issues/3341.

It is allowed to call that function with id set to -1, specifying the
backend by the name instead. We should imitate what is done further down
in that function to allow for that.

NSS may be built without support for the latest SSL/TLS versions,
leading to "SSL version range is not valid" errors when the library
code supports a recent version (e.g. TLS v1.3) but it has explicitly
been disabled.
This change adjusts the maximum SSL version requested by libcurl to
be the maximum supported version at runtime, as long as that version
is at least as high as the minimum version required by libcurl.

The extended warning for checking incorrect COPYRIGHTYEAR is quite
expensive to run, so rather than expecting every developer to do it
we ensure it's turned on locally for Travis.
|
|
Forgetting to bump the year in the copyright clause when hacking has
been quite common among curl developers, but a traditional checksrc
check isn't a good fit as it would penalize anyone hacking on January
1st (among other things). This adds a more selective COPYRIGHTYEAR
check which intends to only cover the currently hacked on changeset.
The check for updated copyright year is currently not enforced on all
files but only on files edited and/or committed locally. This is due to
the amount of files which aren't updated with their correct copyright
year at the time of their respective commit.
To further avoid running this expensive check for every developer, it
adds a new local override mode for checksrc where a .checksrc file can
be used to turn on extended warnings locally.

Commit 7c5837e79280e6abb3ae143dfc49bca5e74cdd11 deprecated the option
making it a manual code-edit operation to turn it back on. The removal
process has thus started and is now documented in docs/DEPRECATE.md so
remove from the TODO to avoid anyone looking for something to pick up
spend cycles on an already in-progress entry.

When compiling a collection of SSL libraries to link against (SSL_LIBS),
ensure all libraries are included. The call `--libs-only-l` can produce
only a subset of found in a `--libs` call (e.x. pthread may be excluded).
Adding `--libs-only-other` ensures other libraries are also included in
the list. This corrects select build environments compiling against a
static version of OpenSSL. Before the change, the following could be
observed:
checking for openssl options with pkg-config... found
configure: pkg-config: SSL_LIBS: "-lssl -lz -ldl -lcrypto -lz -ldl "
configure: pkg-config: SSL_LDFLAGS: "-L/home/jdknight/<workdir>/staging/usr/lib -L/home/jdknight/<workdir>/staging/usr/lib "

curl_multi_wait() was erroneously used from within
curl_easy_perform(). It could lead to it believing there was no socket
to wait for and then instead sleep for a while instead of monitoring the
socket and then miss acting on that activity as swiftly as it should
(causing an up to 1000 ms delay).

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

The tests 20 and 1322 are using getaddrinfo of libc for resolving. In
eglibc-2.19 there is a memory leakage and invalid free bug which
surfaces in some special circumstances (PF_UNSPEC hint with invalid or
non-existent names). The valgrind runs in testing fail in these
situations.
As the tests 20/1322 are not specific on either protocol (IPv4/IPv6)
this commit changes the hints to IPv4 protocol by passing `--ipv4` flag
on the tests' command line. This prevents the valgrind failures.

Session resumption information is not available immediately after a TLS 1.3
handshake. The client must wait until the server has sent a session ticket.
Use OpenSSL's "new session" callback to get the session information and put it
into curl's session cache. For TLS 1.3 sessions, this callback will be invoked
after the server has sent a session ticket.
The "new session" callback is invoked only if OpenSSL's session cache is
enabled, so enable it and use the "external storage" mode which lets curl manage
the contents of the session cache.
A pointer to the connection data and the sockindex are now saved as "SSL extra
data" to make them available to the callback.
This approach also works for old SSL/TLS versions and old OpenSSL versions.

When using c-ares for asyn dns, the dns socket fd was silently closed
by c-ares without curl being aware. curl would then 'realize' the fd
has been removed at next call of Curl_resolver_getsock, and only then
notify the CURLMOPT_SOCKETFUNCTION to remove fd from its poll set with
CURL_POLL_REMOVE. At this point the fd is already closed.
By using ares socket state callback (ARES_OPT_SOCK_STATE_CB), this
patch allows curl to be notified that the fd is not longer needed
for neither for write nor read. At this point by calling
Curl_multi_closed we are able to notify multi with CURL_POLL_REMOVE
before the fd is actually closed by ares.
In asyn-ares.c Curl_resolver_duphandle we can't use ares_dup anymore
since it does not allow passing a different sock_state_cb_data
