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.

Modules within the server using file descriptors for reading and/or writing can call Bool SetNotifyFd(int fd, NotifyFdProcPtr notify_fd, int mask, void *data); mask can be any combination of X_NOTIFY_READ and X_NOTIFY_WRITE. When 'fd' becomes readable or writable, the notify_fd function will be called with the 'fd', the ready conditions and 'data' values as arguments, When the module no longer needs to monitor the fd, it will call void RemoveNotifyFd(int fd); RemoveNotifyFd may be called from the notify function.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-1/+1
| | | | | | | | | | | | | | | | | | | | 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.
