* socket-util: Fix set_dscp for IPv6YAMAMOTO Takashi2014-02-261-1/+14
| | | | | | | | | | | | | | | | | | | Try IPPROTO_IPV6/IPV6_TCLASS socket option as well as IPPROTO_IP/IP_TOS so that this can work for IPv6 sockets. IPPROTO_IP/IP_TOS socket option is, as it's SOL indicates, for IPv4. What happens when it's used for IPv6 sockets? On Linux, it seems to be forwarded to IPv4 code and affects IPv4 part of the socket. (e.g. non-V6ONLY case) But it doesn't seem to be the intention of this function. On other platforms including NetBSD, it just fails with ENOPROTOOPT. Probably this function should take the address family but passing it around lib/*stream*.c would be a bigger change.

| | | | | | | | | | | Commit 2b31d8e713de7 (vlog: Report timestamps in millisecond resolution in log messages.) introduced milliseconds to log messages by default, but the Python version did not ensure that milliseconds were always formatted with 3 digits, so 3.001 was formatted as "3.1" and 3.012 as "3.12", and so on.

* stream-unix: Use rundir as root for relative paths.Pavithra Ramesh2013-02-111-0/+4
| | | | | | | | | | | | | | Until now, "unix:" and "punix:" paths that are not absolute have been considered relative to the current working directory.

* python: Workaround UNIX socket path length limitsJames Page2013-01-161-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | From aa28e8bfb646a54ba91e3545f3c0b9db39eddb7f Mon Sep 17 00:00:00 2001 From: James Page <james.page@ubuntu.com> Date: Wed, 16 Jan 2013 10:52:59 +0000 Subject: [PATCH] python: Workaround UNIX socket path length limits To: dev@openvswitch.org UNIX socket paths have a limit in terms of length. On Linux this is 103 characters. This is a problem in Debian/Ubuntu buildds which can generate quite long paths. This patch works around this issue by detecting when socket connection/binding fails due to this issue and accessing the socket path using a file descriptor path in /proc/self/fd. The workaround is limited to Linux. This is based on similar code in the C parts of OpenvSwitch. Signed-off-by: James Page <james.page@ubuntu.com> Signed-off-by: Ben Pfaff <blp@nicira.com>
* daemon: Start monitor process, not daemon process, in new session.Ben Pfaff2012-12-131-2/+3
| | | | | | | | | | | | | | | | | | | | | | To keep control+C and other signals in the initiating session from killing the monitor process, we need to put the monitor process into its own session. However, until this point, we've only done that for the daemon processes that the monitor started, which means that control+C would kill the monitor but not the daemons that it launched. I don't know of a benefit to putting the monitor and daemon processes in different sessions, as opposed to one new session for both of them, so this change does the latter. daemonize_post_detach() is called from one additional context where we'd want to be in a new session, the worker_start() function, but that function is documented as to be called after daemonize_start(), in which case we will (after this commit) already have called setsid(), so no additional change is required there.

| | | | | | | | | | | | | | When a JSON-RPC session receives bytes, or when it successfully sends queued bytes, then it should count that as activity. However, the code here was reversed, in that it used the wrong check in each place.

* jsonrpc: Treat receiving part of a message as activity.Ben Pfaff2012-09-071-0/+14
| | | | | | | | | | | | | | | Until now, the jsonrpc code has only counted receiving a full JSON-RPC messages as activity. This could theoretically time out, then, while a very long message is in transit or if a slow link is involved. This commit changes this code to count receiving any part of a message as activity. This isn't a problem for OpenFlow connections because OpenFlow messages are at most 64 kB in size. This problem hasn't actually been observed in practice. Bug #12789.

* jsonrpc: Treat draining data from send queue as activity.Ben Pfaff2012-09-071-1/+11
| | | | | | | | | | | | | | | | | | | Until now, the jsonrpc module has used messages received from the remote peer as the sole means to determine that the JSON-RPC connection is up. This could in theory interact badly with a remote peer that stops reading and processing messages from the receive queue when there is a backlog in the send queue for a given connection (ovsdb-server is an example of a program that behaves this way). This commit fixes the problem by expanding the definition of "activity" to include successfully sending JSON-RPC data that was previously queued. The above change is exactly analogous to the similar change made to the rconn library in commit 133f2dc95454 (rconn: Treat draining a message from the send queue as activity.). Bug #12789.

* dirs: dbdir default must be based on sysconfdir.Ben Pfaff2012-08-032-8/+29
| | | | | | | | | | | | | | | Some in-tree and out-of-tree code sets the OVS_SYSCONFDIR environment variable to control where /etc files go (mostly for test purposes). When the database directory (dbdir) was split off from the sysconfdir, the configure-time default continued to be based on the sysconfdir, but overriding the sysconfdir at runtime with OVS_SYSCONFDIR didn't have any effect on the dbdir, which caused a visible change in behavior for code that set the OVS_SYSCONFDIR environment variable. This commit reverts that change in behavior, by basing the dbdir on OVS_SYSCONFDIR if that environment variable is set (but the OVS_DBDIR environment variable is not).
