2019-05-30http2: Stop drain from being permanently set onJosie Huddleston
Various functions called within Curl_http2_done() can have the side-effect of setting the Easy connection into drain mode (by calling drain_this()). However, the last time we unset this for a transfer (by calling drained_transfer()) is at the beginning of Curl_http2_done(). If the Curl_easy is reused for another transfer, it is then stuck in drain mode permanently, which in practice makes it unable to write any data in the new transfer. This fix moves the last call to drained_transfer() to later in Curl_http2_done(), after the functions that could potentially call for a drain. Fixes #3966 Closes #3967 Reported-by: Josie-H
2019-05-16cleanup: remove FIXME and TODO commentsDaniel Stenberg
They serve very little purpose and mostly just add noise. Most of them have been around for a very long time. I read them all before removing or rephrasing them. Ref: #3876 Closes #3883

2019-02-20http2: verify :athority in push promise requestsDaniel Stenberg
RFC 7540 says we should verify that the push is for an "authoritative" server. We make sure of this by only allowing push with an :athority header that matches the host that was asked for in the URL.

2019-01-11urldata: rename easy_conn to just connDaniel Stenberg
We use "conn" everywhere to be a pointer to the connection. Introduces two functions that "attaches" and "detaches" the connection to and from the transfer. Going forward, we should favour using "data->conn" (since a transfer always only has a single connection or none at all) to "conn->data" (since a connection can have none, one or many transfers associated with it and updating conn->data to be correct is error prone and a frequent reason for internal issues). Closes #3442
2018-12-20http2: clear pause stream id if it gets closedDaniel Stenberg

2018-12-08Upon HTTP_1_1_REQUIRED, retry the request with HTTP/1.1Johannes Schindelin
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 #3349 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
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. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297

Closes #3144
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.

2018-04-20http2: avoid strstr() on data not zero terminatedDaniel Stenberg
It's not strictly clear if the API contract allows us to call strstr() on a string that isn't zero terminated even when we know it will find the substring, and clang's ASAN check dislikes us for it. Also added a check of the return code in case it fails, even if I can't think of a situation how that can trigger.

2018-01-11http2: fix incorrect trailer buffer sizeZhouyihai Ding
Prior to this change the stored byte count of each trailer was miscalculated and 1 less than required. It appears any trailer after the first that was passed to Curl_client_write would be truncated or corrupted as well as the size. Potentially the size of some subsequent trailer could be erroneously extracted from the contents of that trailer, and since that size is used by client write an out-of-bounds read could occur and cause a crash or be otherwise processed by client write. The bug appears to have been born in 0761a51 (precedes 7.49.0). Closes https://github.com/curl/curl/pull/2231
