- make sure an already "owned" connection isn't returned unless
multiplexed.
- clear ->data when returning the connection to the cache again
Regression since 7.62.0 (probably in commit 1b76c38904)
Bug: https://curl.haxx.se/mail/lib-2019-03/0064.htmlCloses#3686
AmiSSL is an Amiga native library which provides a wrapper over OpenSSL.
It also requires all programs using it to use bsdsocket.library
directly, rather than accessing socket functions through clib, which
libcurl was not necessarily doing previously. Configure will now check
for the headers and ensure they are included if found.
Closes#3677
* Adjusted unit tests 2056, 2057
* do not generally close connections with CURLAUTH_NEGOTIATE after every request
* moved negotiatedata from UrlState to connectdata
* Added stream rewind logic for CURLAUTH_NEGOTIATE
* introduced negotiatedata::GSS_AUTHDONE and negotiatedata::GSS_AUTHSUCC
* Consider authproblem state for CURLAUTH_NEGOTIATE
* Consider reuse_forbid for CURLAUTH_NEGOTIATE
* moved and adjusted negotiate authentication state handling from
output_auth_headers into Curl_output_negotiate
* Curl_output_negotiate: ensure auth done is always set
* Curl_output_negotiate: Set auth done also if result code is
GSS_S_CONTINUE_NEEDED/SEC_I_CONTINUE_NEEDED as this result code may
also indicate the last challenge request (only works with disabled
Expect: 100-continue and CURLOPT_KEEP_SENDING_ON_ERROR -> 1)
* Consider "Persistent-Auth" header, detect if not present;
Reset/Cleanup negotiate after authentication if no persistent
authentication
* apply changes introduced with #2546 for negotiate rewind logic
Fixes#1261Closes#1975
The check that prevents payload from sending in case of authentication
doesn't check properly if the authentication is done or not.
They're cases where the proxy respond "200 OK" before sending
authentication challenge. This change takes care of that.
Fixes#2431Closes#3669
Coverity warned for two potentional "Use after free" cases. Both are false
positives because the memory wasn't used, it was only the actual pointer
value that was logged.
The fix still changes the order of execution to avoid the warnings.

Closes#3671
This code was once used for the non multi-interface using code path, but
ever since easy_perform was turned into a wrapper around the multi
interface, this code path never runs.
Closes#3666
- Inherit SSL options for the doh handle but not SSL client certs,
SSL ALPN/NPN, SSL engine, SSL version, SSL issuer cert,
SSL pinned public key, SSL ciphers, SSL id cache setting,
SSL kerberos or SSL gss-api settings.
- Fix inheritance of verbose setting.
- Inherit NOSIGNAL.
There is no way for the user to set options for the doh (DNS-over-HTTPS)
handles and instead we inherit some options from the user's easy handle.
My thinking for the SSL options not inherited is they are most likely
not intended by the user for the DOH transfer. I did inherit insecure
because I think that should still be in control of the user.
Prior to this change doh did not work for me because CAINFO was not
inherited. Also verbose was set always which AFAICT was a bug (#3660).

Fixes#3617Closes#3642
If the state machine isn't complete, didn't fail and it didn't return
due to blocking it can just as well loop again.
This addresses the problem with SFTP directory listings where we would
otherwise return back to the parent and as the multi state machine
doesn't have any code for using CURLM_CALL_MULTI_PERFORM for as long the
doing phase isn't complete, it would return out when in reality there
was more data to deal with.
Fixes#3506Closes#3644
- Change closure handle to receive verbose setting from the easy handle
most recently added via curl_multi_add_handle.
The closure handle is a special easy handle used for closing cached
connections. It receives limited settings from the easy handle most
recently added to the multi handle. Prior to this change that did not
include verbose which was a problem because on connection shutdown
verbose mode was not acknowledged.

Closes https://github.com/curl/curl/pull/3618
- no need to have them protocol specific
- no need to set pointers to them with the Curl_setup_transfer() call
- make Curl_setup_transfer() operate on a transfer pointer, not
connection
- switch some counters from long to the more proper curl_off_t type
Closes#3627
When a transfer is done, the resolver thread will be brought down. That
could accidentally generate an error message in the error buffer even
though this is not an error situationand the transfer would still return
OK. An application that still reads the error buffer could find a
"Could not resolve host: [host name]" message there and get confused.

Without it set, we would unwillingly triger the "HTTP error before end
of send, stop sending" condition even if the entire POST body had been
sent (since it wouldn't know the expected size) which would
unnecessarily log that message and close the connection when it didn't
have to.

Follow-up to 8eddb8f425.
If the cookieinfo pointer is NULL there really is nothing to save.
Without this fix, we got a problem when a handle was using shared object
with cookies and is told to "FLUSH" it to file (which worked) and then
the share object was removed and when the easy handle was closed just
afterwards it has no cookieinfo and no cookies so it decided to save an
empty jar (overwriting the file just flushed).
Test 1905 now verifies that this works.

Closes#3621
This allows the compiler to pack and align the structs better in
memory. For a rather feature-complete build on x86_64 Linux, gcc 8.1.2
makes the Curl_easy struct 4.9% smaller. From 6312 bytes to 6000.
Removed an unused struct field.
No functionality changes.
Closes#3610
Instead of using a fixed 256 byte buffer in the connectdata struct.
In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.
This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.

Add support for Ephemeral elliptic curve Diffie-Hellman key exchange
algorithm option when selecting ciphers. This became available on the
Win10 SDK.
Closes https://github.com/curl/curl/pull/3608
Failing to do so would make the CURLINFO_TOTAL_TIME timeout to not get
updated correctly and could end up getting reported to the application
completely wrong (way too small).

- Split off connection shutdown procedure from Curl_disconnect into new
function conn_shutdown.
- Change the shutdown procedure to close the sockets before
disassociating the transfer.
Prior to this change the sockets were closed after disassociating the
transfer so SOCKETFUNCTION wasn't called since the transfer was already
disassociated. That likely came about from recent work started in
Jan 2019 (#3442) to separate transfers from connections.

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.
