Commit: 6d75ccba6f2ebff3c3485f7e2dfceeda38c62c1b https://github.com/asalkeld/libqb/commit/6d75ccba6f2ebff3c3485f7e2dfceeda... Author: Jeremy Fitzhardinge <jeremy(a)exablox.com&gt; Date: 2012-09-05 (Wed, 05 Sep 2012) Changed paths: M lib/ipc_us.c Log Message: ----------- ipc_us: on Linux, set SO_PASSCRED on the sending socket too Linux doesn't pass credential information by default, only when it has been specifically requested with SO_PASSCRED. This means there's a race between when the ipc server side has set up and is listening on the socket, and when the client may connect; if the client connects and sends its first message before the server has set SO_PASSCRED on the socket, then there will be no ucred information associated with the message. The fix is to set SO_PASSCRED on the client socket as well, so that the message will always have a ucred associated with it when the server reads it. Without this change, around 1% of cpg_model_initialize() calls fail with CS_ERR_ACCESS. (This Linux behaviour was introduced just on a year ago in 16e5726269611b71c930054ffe9b858c1cea88eb "af_unix: dont send SCM_CREDENTIALS by default".)
