* llcache: Actually pass on certificate chain properlyDaniel Silverstone2020-05-041-5/+10
| | | | Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* Low level cache: Squash use of uninitialised value.Michael Drake2020-02-241-3/+2
| | | | | | | Coverity issue: CID 1419828: Memory - corruptions (UNINIT) >>> Using uninitialized value "output_length".
* llcache: Persist anything available during llcache_finaliseDaniel Silverstone2020-02-231-0/+5

* Keep the complete certificate chain from a fetchVincent Sanders2020-02-231-195/+90
| | | | | | | | | Instead of extracting information from the X509 certificate chain in the fetcher the entire chain is propagated in Distinguished Encoding Rules (DER) format. This allows all the information contained in a certificate chain to be retained which can subsequently be presented to the user

* llcache: Support storing SSL certificate dataDaniel Silverstone2019-11-301-3/+68
| | | | | | | In order to support persisting SSL data we first have to store it and support catching up new users. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* llcache: Avoid putting local content in the disc cache.Michael Drake2019-11-101-0/+39

* llcache: Split out scheme is cachable check.Michael Drake2019-11-101-27/+38
|
* llcache: URLs with data scheme are cachable.Michael Drake2019-11-101-1/+4
|
* llcache: Uncachable scheme checks don't need to be caseless.Michael Drake2019-11-091-4/+6
|
* llcache: Allow file and resource schemes to be cached.Michael Drake2019-11-091-7/+11
| | | | | This means things like the default css file and adblock css file are only loaded and parsed once.
* Improve timeout error messagingVincent Sanders2019-10-281-9/+52

* Reimplement handling of BAD_AUTH inside browser_windowDaniel Silverstone2019-08-061-1/+1
| | | | | | | | | | | | | We now handle authentication requests via an `about:` page which presents a nice form built into the browser window. In order to do this, we add internal navigation as a concept to the browser window and we strip the 401login support from all frontends except monkey. The 401login callback is now intended for password safe type support rather than an immediately interactive prompt. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* Excise the llcache query pathway.Daniel Silverstone2019-08-051-89/+24
| | | | | | | | In further preparation for the auth and cert queries being handled as special contents from `about:` this excises the query pathway from the llcache pretty much entirely. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* Migrate SSL certificate storage to the browser windowDaniel Silverstone2019-08-051-9/+12
| | | | | | | | | | * Fetchers now provide the certificates before headers * This is propagated all the way to the browser window * When a query occurs, we retrieve it from there and fire the query with those stored certificates. * The serial number is a bignum, store it as hex.

* llcache: Do not delete objects if they were iterator targetsDaniel Silverstone2019-08-041-1/+1

* llcache: pass the cb_pw in query_finishedDaniel Silverstone2019-08-041-0/+1

* Migrate query dispatch up from llcache to hlcacheDaniel Silverstone2019-08-031-37/+37
| | | | | | | | | | | | As a first step in refactoring query handling to be managed by `browser_window`, this migrates the calling of the query handler from the llcache object code up to the hlcache. In theory this may result in multiple queries happening for one object, but we mitigate multiple-responses in the llcache so all should be well.

* llcache: Ensure we preserve iteratorness when sending messagesDaniel Silverstone2019-08-021-1/+2
| | | | | | | | | In order to prevent a problem where iterating causes an abort which causes an iteration which clears the iteratorness of a user allowing it to delete itself causing a segfault, preserve the iteratorness when iterating in send_message Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* llcache: Use last_modified instead of dateDaniel Silverstone2019-08-021-2/+2
| | | | | | | | | When sending an If-Modified-Since header we should use the `last_modified` rather than the `date` property of the cached object in order to not incorrectly assume things have a modification date when they do not. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* llcache: Abort cleanly if called back during shutdownDaniel Silverstone2019-06-151-0/+7
| | | | | | | | | | In order to help us debug shutting down with active fetches, this will abort the process cleanly if we get a callback to an "active" llcache handle after the abort process has actually killed them all. This can happen with deferred fetcher aborts in the cURL fetcher. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

|
* HSTS: prevent llcache being niceJohn-Mark Bell2018-04-221-9/+25
| | | | | | | | If the server has defined a HSTS policy, then the user no longer gets to click-through a garbage certificate. Additionally, if the server has provided a HSTS policy, it should do TLS properly, so don't permit client-driven TLS version downgrades in that case, either.

* create date and time to seconds since epoch processing utility functionVincent Sanders2016-04-161-29/+53
| | | | | | | currently NetSurf uses curl_getdate to convert textural date and time strings into seconds since epoch. It is betetr to move this functionality to a utility function so curl_getdate can easily be replaced if required.
* complete the rename of the gui browser tableVincent Sanders2016-04-161-4/+4
| | | | | | When the operations tables were created the browser table was renamed to miscellaneous except the actual rename patch was never applied, this fixes that situation.
* Fix size_t printf formattingVincent Sanders2016-03-171-6/+7
| | | | | | | The printf formatting for size_t is set in c99 as %zu but in windows it is %Iu this is solved by adding and inttypes style PRI macro for size_t This also uses this macro everywhere size_t is formatted.

* Add support for retrying timed-out cURL fetches.Daniel Silverstone2015-11-101-0/+19
| | | | | | | | | | | | | This is an attempt to amelioriate the situation found in #2384 where we see the cURL connect() failing to complete. Based on the pcap from the bug log, we believe that RISC OS is likely failing to signal the completion of the connection to cURL. As such, cURL times out. This change permits retries of timed out connections in the hope that a fresh socket FD might subsequently function correctly. The defaults chosen mean that the previous behaviour of 30 seconds before timeout is reported will remain the same, but in that time we will make 3 separate attempts to connect the socket.
* Fix error reporting from fetch_startVincent Sanders2015-06-241-26/+40
| | | | | | | Any fetch start error was being reported as "out of memory" which was clearly insufficient. Foe example bad urls (reported was file:// with a missing /) were causing a warn_user with out of memory. This change now at least causes a "bad url" message.
