2016-06-06ipvs: update real-server binding of outgoing connections in SIP-peMarco Angaroni
Previous patch that introduced handling of outgoing packets in SIP persistent-engine did not call ip_vs_check_template() in case packet was matching a connection template. Assumption was that real-server was healthy, since it was sending a packet just in that moment. There are however real-server fault conditions requiring that association between call-id and real-server (represented by connection template) gets updated. Here is an example of the sequence of events: 1) RS1 is a back2back user agent that handled call-id1 and call-id2 2) RS1 is down and was marked as unavailable 3) new message from outside comes to IPVS with call-id1 4) IPVS reschedules the message to RS2, which becomes new call handler 5) RS2 forwards the message outside, translating call-id1 to call-id2 6) inside pe->conn_out() IPVS matches call-id2 with existing template 7) IPVS does not change association call-id2 <-> RS1 8) new message comes from client with call-id2 9) IPVS reschedules the message to a real-server potentially different from RS2, which is now the correct destination This patch introduces ip_vs_check_template() call in the handling of outgoing packets for SIP-pe. And also introduces a second optional argument for ip_vs_check_template() that allows to check if dest associated to a connection template is the same dest that was identified as the source of the packet. This is to change the real-server bound to a particular call-id independently from its availability status: the idea is that it's more reliable, for in->out direction (where internal network can be considered trusted), to always associate a call-id with the last real-server that used it in one of its messages. Think about above sequence of events where, just after step 5, RS1 returns instead to be available. Comparison of dests is done by simply comparing pointers to struct ip_vs_dest; there should be no cases where struct ip_vs_dest keeps its memory address, but represent a different real-server in terms of ip-address / port.

2016-06-05devpts: Make each mount of devpts an independent filesystem.Eric W. Biederman
The /dev/ptmx device node is changed to lookup the directory entry "pts" in the same directory as the /dev/ptmx device node was opened in. If there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx uses that filesystem. Otherwise the open of /dev/ptmx fails. The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that userspace can now safely depend on each mount of devpts creating a new instance of the filesystem. Each mount of devpts is now a separate and equal filesystem. Reserved ttys are now available to all instances of devpts where the mounter is in the initial mount namespace. A new vfs helper path_pts is introduced that finds a directory entry named "pts" in the directory of the passed in path, and changes the passed in path to point to it. The helper path_pts uses a function path_parent_directory that was factored out of follow_dotdot. In the implementation of devpts: - devpts_mnt is killed as it is no longer meaningful if all mounts of devpts are equal. - pts_sb_from_inode is replaced by just inode->i_sb as all cached inodes in the tty layer are now from the devpts filesystem. - devpts_add_ref is rolled into the new function devpts_ptmx. And the unnecessary inode hold is removed. - devpts_del_ref is renamed devpts_release and reduced to just a deacrivate_super. - The newinstance mount option continues to be accepted but is now ignored. In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as they are never used. Documentation/filesystems/devices.txt is updated to describe the current situation. This has been verified to work properly on openwrt-15.05, centos5, centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3, ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1, slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01. With the caveat that on centos6 and on slackware-14.1 that there wind up being two instances of the devpts filesystem mounted on /dev/pts, the lower copy does not end up getting used.

2016-06-03qed: Fix next-ptr chains for BE / 32-bitYuval Mintz
Commit a91eb52abb50 ("qed: Revisit chain implementation") contains an incorrect implementation for BE platforms, as device's regpairs containing addresses are LE and they're not converted correctly when read back. In addition, it raises a compilation warning for 32-bit platforms where dma_addr_t is a 32-bit variable.
