Before commit cf88363d, the server would simply disconnect the client. After that commit, it attempts to gracefully ignore the request by remembering how long the client specified the request to be, and ignoring that many bytes. However, if a client sends a BigReq header with a large size and disconnects before actually sending the rest of the specified request, the server will reuse the ConnectionInput buffer without resetting the ignoreBytes field. This makes the server ignore new X clients' requests. This fixes that behavior by resetting the ignoreBytes field when putting the ConnectionInput buffer back on the FreeInputs list.

However, it neglected to handle the case where it returns a long read, which happens when the client has another request in the queue after the bogus large one. Handle the long read case by subtracting the smaller of 'needed' and 'gotnow' from oci->ignoreBytes. If needed < gotnow, simply subtract the two, leaving gotnow equal to the number of extra bytes read. Since the code immediately following the (oci->ignoreBytes > 0) block tries to handle the next request, advance oci->bufptr immediately instead of setting oci->lenLastReq and letting the next call to ReadRequestFromClient do it. Fixes the XTS pChangeKeyboardMapping-3 test.

This makes the client receive SIGPIPE the next time it tries to send something. The X Test Suite sends requests that are too big when the test specifies the TOO_LONG test type. When the client receives SIGPIPE, XTS marks it as UNRESOLVED, which counts as a failure. Instead, remember how long the request is supposed to be and then return that size. Dispatch() checks the length and sends BadLength to the client. Then, whenever oci->ignoreBytes is nonzero, ignore the data read instead of trying to process it as a request.

When ConnectionOutput->count is negative, InsertIOV does not actually insert an IOV, and FlushClient goes into an infinite loop of writev(fd, iov, 0) [an empty list].

Only calls FlushCallbacks when we're actually flushing data to a client. The unnecessary FlushCallback calls could cause significant performance degradation with compositing, which is significantly reduced even without any driver changes. 2. By passing the ClientPtr to FlushCallbacks, drivers can completely eliminate unnecessary flushing of GPU commands by keeping track of whether we're flushing any XDamageNotify events to the client for which the corresponding rendering commands haven't been flushed to the GPU yet.

However, this neglected the possibility that additional data, in the form of 'extraBuf' would be passed to FlushClient from other code paths. If the output buffer happened to be empty at that time, the extra data would never be written to the client. This is fixed by checking the total data to be written, which includes both pending and extra data, instead of just the pending data.

X terminals receiving X traffic, or receiving user input would use the 3 minute value; X terminals without any network traffic would use a longer value. However, this was actually broken -- any activity in the X server, either client requests or user input, would end up resetting the keepalive timeout, so a user mashing on the keyboard would never discover that the XDMCP master had disappeared and have the session terminated, which was precisely the design goal of the XDMCP keepalive mechanism. Instead of attempting to fix this, accept the cost of a pair of XDMCP packets once every three minutes and just perform keepalives regularly. This will also make reworking the block and wakeup handler APIs to eliminate select masks easier.

Quote Alan Coopersmith: "The consumer was in past versions of the headers now located in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h, all the event definitions were only available if NEED_EVENTS were defined, and all the reply definitions required NEED_REPLIES. Looks like Xproto.h dropped them by X11R6.3, which didn't have the #ifdef's anymore, so these are truly ancient now."

* Remove unneccesary casts from WriteToClient callsAlan Coopersmith2016-07-051-1/+1
| | | | | | | | | | | | | | Casting return to (void) was used to tell lint that you intended to ignore the return value, so it didn't warn you about it. Casting the third argument to (char *) was used as the most generic pointer type in the days before compilers supported C89 (void *) (except for a couple places it's used for byte-sized pointer math).

* 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.
