* Make WriteToClient take a const void * like any decent IO write function.Kristian Høgsberg2016-07-052-4/+6
| | | | | Enough with the casting. Doesn't break API or even ABI, but does make a lot of silly casts superfluos.
* Make WriteEventsToClient/WriteToClient no-op on fake or dead clients.Jamey Sharp2016-07-051-3/+5
| | | | | | | | | | | | | | | | | | This matches the test in TryClientEvents, and is a superset of tests done by the callers of these functions. The consequence of forgetting these tests is a server crash, so they're always desirable. In my opinion, it's better to not require the callers to remember to do these checks. For callers that don't do very much work before calling WriteToClient or WriteEventsToClient, I've removed the redundant checks.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-2817-60/+60
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.

* dix: integer overflow in GetHosts() [CVE-2014-8092 2/4]Alan Coopersmith2015-02-161-0/+6
| | | | | | | | | | | | | | | | | | | | | GetHosts() iterates over all the hosts it has in memory, and copies them to a buffer. The buffer length is calculated by iterating over all the hosts and adding up all of their combined length. There is a potential integer overflow, if there are lots and lots of hosts (with a combined length of > ~4 gig). This should be possible by repeatedly calling ProcChangeHosts() on 64bit machines with enough memory. This patch caps the list at 1mb, because multi-megabyte hostname lists for X access control are insane. v2: backport to nx-libs 3.6.x (Mike DePaulo) v3: human-readable version of "1 MB" (Mihai Moldovan) Reported-by: Ilja Van Sprundel <ivansprundel@ioactive.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: os/access.c

* unchecked malloc may allow unauthed client to crash Xserver [CVE-2014-8091]Alan Coopersmith2015-02-141-0/+4
| | | | | | | | | | | | | | | | | | authdes_ezdecode() calls malloc() using a length provided by the connection handshake sent by a newly connected client in order to authenticate to the server, so should be treated as untrusted. It didn't check if malloc() failed before writing to the newly allocated buffer, so could lead to a server crash if the server fails to allocate memory (up to UINT16_MAX bytes, since the len field is a CARD16 in the X protocol).
