Previously we did not handle EOF from underlying transport socket and
wrongly just returned error code CURL_AGAIN from http2_recv, which
caused busy loop since socket has been closed. This patch adds the
code to handle EOF situation and tells the upper layer that we got
EOF.

Removed ISC_REQ_* flags from calls to InitializeSecurityContext to fix
bug in NTLM handshake for HTTP proxy authentication.
NTLM handshake for HTTP proxy authentication failed with error
SEC_E_INVALID_TOKEN from InitializeSecurityContext for certain proxy
servers on generating the NTLM Type-3 message.
The flag ISC_REQ_CONFIDENTIALITY seems to cause the problem according
to the observations and suggestions made in a bug report for the
QT project (https://bugreports.qt-project.org/browse/QTBUG-17322).
Removing all the flags solved the problem.

As a sort of step forward, this script will now first try to get the
data from the HTTPS URL using curl, and only if that fails it will
switch back to the HTTP transfer using perl's native LWP functionality.
To reduce the risk of this script being tricked.
Using HTTPS to get a cert bundle introduces a chicken-and-egg problem so
we can't really ever completely disable HTTP, but chances are that most
users already have a ca cert bundle that trusts the mozilla.org site
that this script downloads from.
A future version of this script will probably switch to require a
dedicated "insecure" command line option to allow downloading over HTTP
(or unverified HTTPS).

By not detecting and rejecting domain names for partial literal IP
addresses properly when parsing received HTTP cookies, libcurl can be
fooled to both send cookies to wrong sites and to allow arbitrary sites
to set cookies for others.

Historically the default "unknown" value for progress.size_dl and
progress.size_ul has been zero, since these values are initialized
implicitly by the calloc that allocates the curl handle that these
variables are a part of. Users of curl that install progress
callbacks may expect these values to always be >= 0.
Currently it is possible for progress.size_dl and progress.size_ul
to by set to a value of -1, if Curl_pgrsSetDownloadSize() or
Curl_pgrsSetUploadSize() are passed a "size" of -1 (which a few
places currently do, and a following patch will add more). So
lets update Curl_pgrsSetDownloadSize() and Curl_pgrsSetUploadSize()
so they make sure that these variables always contain a value that
is >= 0.
Updates test579 and test599.

As the current element in the list is free()d by Curl_llist_remove(),
when the associated connection is pending, reworked the loop to avoid
accessing the next element through e->next afterward.

... as the struct is free()d in the end anyway. It was first pointed out
to me that one of the ->msglist assignments were supposed to have been
->pending but was a copy and paste mistake when I realized none of the
clearing of pointers had to be there.
|
|
... instead of scanning through all handles, stash only the actual
handles that are in that state in the new ->pending list and scan that
list only. It should be mostly empty or very short. And only used for
pipelining.
This avoids a rather hefty slow-down especially notable if you add many
handles to the same multi handle. Regression introduced in commit
0f147887 (version 7.30.0).

Introducing Curl_expire_latest(). To be used when we the code flow only
wants to get called at a later time that is "no later than X" so that
something can be checked (and another timeout be added).
The low-speed logic for example could easily be made to set very many
expire timeouts if it would be called faster or sooner than what it had
set its own timer and this goes for a few other timers too that aren't
explictiy checked for timer expiration in the code.
If there's no condition the code that says if(time-passed >= TIME), then
Curl_expire_latest() is preferred to Curl_expire().
If there exists such a condition, it is on the other hand important that
Curl_expire() is used and not the other.

While waiting for a host resolve, check if the host cache may have
gotten the name already (by someone else), for when the same name is
resolved by several simultanoues requests.
The resolver thread occasionally gets stuck in getaddrinfo() when the
DNS or anything else is crappy or slow, so when a host is found in the
DNS cache, leave the thread alone and let itself cleanup the mess.

If the --cacert option is used with a CA certificate bundle that
contains multiple CA certificates, iterate through it, adding each
certificate as a trusted root CA.

This is usually due to failed auth. There's no point in us keeping such
a connection alive since it shouldn't be re-used anyway.

At this point I can build libcurl on windows. It provides at least the same
list of protocols as for linux build and works with our software.

This was done to make sure NTLM state that is bound to a connection
doesn't survive and gets used for the subsequent request - but
disconnects can also be done to for example make room in the connection
cache and thus that connection is not strictly related to the easy
handle's current operation.
The http authentication state is still kept in the easy handle since all
http auth _except_ NTLM is connection independent and thus survive over
multiple connections.

Problem: if CURLOPT_FORBID_REUSE is set, requests using NTLM failed
since NTLM requires multiple requests that re-use the same connection
for the authentication to work
Solution: Ignore the forbid reuse flag in case the NTLM authentication
handshake is in progress, according to the NTLM state flag.
Fixed known bug #77.

Corrected a number of the error codes that can be returned from the
Curl_sasl_create_gssapi_security_message() function when things go
wrong.
It makes more sense to return CURLE_BAD_CONTENT_ENCODING when the
inbound security challenge can't be decoded correctly or doesn't
contain the KERB_WRAP_NO_ENCRYPT flag and CURLE_OUT_OF_MEMORY when
EncryptMessage() fails. Unfortunately the previous error code of
CURLE_RECV_ERROR was a copy and paste mistakes on my part and should
have been correct in commit 4b491c675f :(
