* Fix a bug in PEM_X509_INFO_read_bio(3) that is very likely to causeschwarze2020-07-234-22/+211
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | use-after-free and double-free issues in calling programs. The bug was introduced in SSLeay-0.6.0 released on June 21, 1996 and has been present since OpenBSD 2.4. I found the bug while documenting the function. The bug could bite in two ways that looked quite different from the perspective of the calling code: * If a stack was passed in that already contained some X509_INFO objects and an error occurred, all the objects passed in would be freed, but without removing the freed pointers from the stack, so the calling code would probable continue to access the freed pointers and eventually free them a second time. * If the input BIO contained at least two valid PEM objects followed by at least one PEM object causing an error, at least one freed pointer would be put onto the stack, even though the function would return NULL rather than the stack. But the calling code would still have a pointer to the stack, so it would be likely to access the new bogus pointers sooner or later. Fix all this by remembering the size of the input stack on entry and cutting it back to exactly that size when exiting due to an error, but no further. While here, do some related cleanup: * Garbage collect the automatic variables "error" and "i" which were only used at one single place each. * Use NULL rather than 0 for pointers. I like bugfixes that make the code four lines shorter, reduce the number of variables by one, reduce the number of brace-blocks by one, reduce the number if if-statements by one, and reduce the number of else-clauses by one.

* Add support for timeconting in userland.pirofti2020-07-066-6/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | This diff exposes parts of clock_gettime(2) and gettimeofday(2) to userland via libc eliberating processes from the need for a context switch everytime they want to count the passage of time. If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others! OK from at least kettenis@, cheloha@, naddy@, sthen@
* Add a missing circular_init() call in the TLS ordering test.jsing2020-07-041-1/+3
| | | | | | | This makes the regress work correctly again - this was previously masked by the fact that tls_close() (and hence SSL_shutdown()) was draining the circular buffer, whereas now we're leaving data behind from a previous test, resulting in the ordering test failing.

* Make the message type available to the extension functionstb2020-07-032-167/+181
| | | | | | | | | | | | | | Some TLS extensions need to be treated differently depending on the handshake message they appear in. Over time, various workarounds and hacks were used to deal with the unavailability of the message type in these functions, but this is getting fragile and unwieldy. Having the message type available will enable us to clean this code up and will allow simple fixes for a number of bugs in our handling of the status_request extension reported by Michael Forney. This approach was suggested a while ago by jsing. ok beck jsing

| | | | | | | | | | | | | When first called, queue and send a close notify, before returning 0 or 1 to indicate if a close notify has already been received from the peer. If called again only attempt to read a close notify if there is no pending application data and only read one record from the wire. In particular, this avoids continuing to read application data where the peer continues to send application data. Issue noted by naddy@ with ftp(1). ok jca@ tb@
