* POSIX: add a maximum number of iterations to HANDLE_EINTRjln@chromium.org2013-01-231-4/+22
| | | | | | | | | | | | | | | In Debug builds, we add a maximum of 100 iterations to HANDLE_EINTR. After more than 100 iterations, the caller will see an EINTR. This is to prevent hard to debug infinite or long lasting loops in case a EINTR storm happens because of a bug. BUG=169416 NOTRY=true Review URL: https://chromiumcodereview.appspot.com/12038034 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@178174 0039d316-1c4b-4281-b951-d872f2087c98
* Use SOCK_SEQPACKET for synchronous IPC.glider@google.com2013-01-183-22/+103
| | | | | | | | | | | | | | This is a copy of https://codereview.chromium.org/11738003 by mnissler@chromium.org SOCK_DGRAM fails in case the other end of the connection dies before sending a reply. This causes recvmsg() calls on the socket to hang, which results in stuck processes sticking around after running tests. BUG=chromium:166528 TEST=No more stuck --type=zygote processes in browser_tests and content_browsertests.

* Linux sandbox: add a new low-level broker process mechanism.jln@chromium.org2012-12-141-1/+8
| | | | | | | | | | | | | | | | | We add a new low-level broker process mechanism that can be async signal safe and is suitable for use in the seccomp-bpf sandbox. Also fix UnixDomainSocket::SendMsg() to never generate a SIGPIPE.

* linux: Crash browser on too-big messages to zygote.derat@chromium.org2012-10-122-4/+7
| | | | | | | | | | | | | | | | | | | This adds CHECKs to the browser if it attempts to send a message to the zygote that exceeds the maximum message size (which causes an EMSGSIZE error in the zygote) or that contains too many file descriptors. I'm hoping that this will help make the source of the problem more apparent when we hit the message size limit, which we appear to have done multiple times (it was originally 1 KB and is now 2 KB).
