      fs,userns: Change inode_capable to capable_wrt_inode_uidgid · 23adbe12
      Andy Lutomirski 提交于
      The kernel has no concept of capabilities with respect to inodes; inodes
      exist independently of namespaces.  For example, inode_capable(inode,
      CAP_LINUX_IMMUTABLE) would be nonsense.
      
      This patch changes inode_capable to check for uid and gid mappings and
      renames it to capable_wrt_inode_uidgid, which should make it more
      obvious what it does.
      
      Fixes CVE-2014-4014.

       "The largest piece is a long-overdue rewrite of the xdr code to remove
        some annoying limitations: for example, there was no way to return
        ACLs larger than 4K, and readdir results were returned only in 4k
        chunks, limiting performance on large directories.
      
        Also:
              - part of Neil Brown's work to make NFS work reliably over the
                loopback interface (so client and server can run on the same
                machine without deadlocks).  The rest of it is coming through
                other trees.
              - cleanup and bugfixes for some of the server RDMA code, from
                Steve Wise.
              - Various cleanup of NFSv4 state code in preparation for an
                overhaul of the locking, from Jeff, Trond, and Benny.
              - smaller bugfixes and cleanup from Christoph Hellwig and

      RDMA/core: Add support for iWARP Port Mapper user space service · 30dc5e63
      Tatyana Nikolova 提交于
      This patch adds iWARP Port Mapper (IWPM) Version 2 support.  The iWARP
      Port Mapper implementation is based on the port mapper specification
      section in the Sockets Direct Protocol paper -
      http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf
      
      Existing iWARP RDMA providers use the same IP address as the native
      TCP/IP stack when creating RDMA connections.  They need a mechanism to
      claim the TCP ports used for RDMA connections to prevent TCP port
      collisions when other host applications use TCP ports.  The iWARP Port
      Mapper provides a standard mechanism to accomplish this.  Without this
      service it is possible for RDMA application to bind/listen on the same
      port which is already being used by native TCP host application.  If
      that happens the incoming TCP connection data can be passed to the
      RDMA stack with error.
      
      The iWARP Port Mapper solution doesn't contain any changes to the
      existing network stack in the kernel space.  All the changes are
      contained with the infiniband tree and also in user space.
      
      The iWARP Port Mapper service is implemented as a user space daemon
      process.  Source for the IWPM service is located at
      http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary
      
      The iWARP driver (port mapper client) sends to the IWPM service the
      local IP address and TCP port it has received from the RDMA
      application, when starting a connection.  The IWPM service performs a
      socket bind from user space to get an available TCP port, called a
      mapped port, and communicates it back to the client.  In that sense,
      the IWPM service is used to map the TCP port, which the RDMA
      application uses to any port available from the host TCP port
      space. The mapped ports are used in iWARP RDMA connections to avoid
      collisions with native TCP stack which is aware that these ports are
      taken. When an RDMA connection using a mapped port is terminated, the
      client notifies the IWPM service, which then releases the TCP port.
      
      The message exchange between the IWPM service and the iWARP drivers
      (between user space and kernel space) is implemented using netlink
      sockets.
      
      1) Netlink interface functions are added: ibnl_unicast() and
         ibnl_mulitcast() for sending netlink messages to user space
      
      2) The signature of the existing ibnl_put_msg() is changed to be more
         generic
      
      3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW
         corresponding to the two iWarp drivers - nes and cxgb4 which use
         the IWPM service
      
      4) Enums are added to enumerate the attributes in the netlink
         messages, which are exchanged between the user space IWPM service
         and the iWARP drivers

      This function is supposed to return true if the new load imbalance is
      worse than the old one.  It didn't.  I can only hope brown paper bags
      are in style.
      
      Now things converge much better on both the 4 node and 8 node systems.
      
      I am not sure why this did not seem to impact specjbb performance on the
      4 node system, which is the system I have full-time access to.

      Don't trigger congestion wait on dirty-but-not-writeout pages · b738d764
      Linus Torvalds 提交于
      shrink_inactive_list() used to wait 0.1s to avoid congestion when all
      the pages that were isolated from the inactive list were dirty but not
      under active writeback.  That makes no real sense, and apparently causes
      major interactivity issues under some loads since 3.11.
      
      The ostensible reason for it was to wait for kswapd to start writing
      pages, but that seems questionable as well, since the congestion wait
      code seems to trigger for kswapd itself as well.  Also, the logic behind
      delaying anything when we haven't actually started writeback is not
      clear - it only delays actually starting that writeback.
      
      We'll still trigger the congestion waiting if
      
       (a) the process is kswapd, and we hit pages flagged for immediate
           reclaim
      
       (b) the process is not kswapd, and the zone backing dev writeback is
           actually congested.
      
      This probably needs to be revisited, but as it is this fixes a reported
      regression.

      Revert "x86/smpboot: Initialize secondary CPU only if master CPU will wait for it" · bb077d60
      Linus Torvalds 提交于
      This reverts commit 3e1a878b.
      
      It came in very late, and already has one reported failure: Sitsofe
      reports that the current tree fails to boot on his EeePC, and bisected
      it down to this.  Rather than waste time trying to figure out what's
      wrong, just revert it.
