A client can send a big request where the 32B "length" field has value 0. When the big request header is removed and the length corrected, the value will underflow to 0xFFFFFFFF. Functions processing the request later will think that the client sent much more data and may touch memory beyond the receive buffer. -- From b747da5 Mon Sep 17 00:00:00 2001 From: Nathan Kidd <nkidd@opentext.com> Date: Fri, 9 Jan 2015 10:15:46 -0500 Subject: Unvalidated extra length in ProcEstablishConnection (CVE-2017-12176)
…ializing 'present_get_ust_msc_ptr')
- BlockHandler() timeout value changed from struct timeval ** to int ** that has a millisecond value. - avoid a NULL ptr deref in ProcXF86BigfontQueryFont() and make some code actually able to be run.
Undo diff to upstream. There's a good chance we aren't using this code at all.
It was introduced as one of the patches fixing https://bugs.freedesktop.org/show_bug.cgi?id=28181 This is marked fixed upstream, and was spotted on non-NetBSD, so it's very likely to be unnecessary. This diff was causing a double-free, causing Xorg to crash when closing pkgsrc/emulators/{retroarch,nestopia}. This is most likely a problem that became more evident from jemalloc debug which is filling free'd memory with 0x5a5a5a... Fixes PR xsrc/54246.
When uefi booting without driver-specific GPU support, wsfb is the only choice for a graphical driver. While here, combine the wsfb cases.
Not the best option without functional GLAMOR, but it does work.
…aki. I've finally contacted with Yamasaki-san and he kindly answered "no objection to change them to 2 clause license" in private mail. Diffs to be committed have also been confirmed by him. We appreciate all his contribution to early NetBSD/x68k.

On certain setups, it might still be useful to force a particular cursor size via xorg.conf. For example, if on a system the automatic probes fail, or if the user wants a particular cursor size, that is higher that the minimum size. Signed-off-by: stefan11111 <stefan11111@shitposting.expert>
