svn commit: r268362 - head/sys/cam/ctl

2014-07-07 Thread Alexander Motin

Date: Mon Jul  7 09:37:22 2014
New Revision: 268362
URL: http://svnweb.freebsd.org/changeset/base/268362

Log:
  Teach ctl_add_initiator() to dynamically allocate IIDs from pool.
  
  If port passed negative IID value, the function will try to allocate IID
  from the pool of unused, based on passed wwpn or name arguments.  It does
  all its best to make IID unique and persistent across reconnects.
  
  This makes persistent reservation properly work for iSCSI.  Previously,
  in case of reconnects, reservation could be unexpectedly lost, or even
  migrate between intiators.

Log:
  Don't call crdup nor uifind under vnode lock.
  
  A locked vnode can get into the way of satisyfing malloc with M_WATOK.
  
  This is a fixup to r268087.

svn commit: r268376 - head/bin/rm

2014-07-07 Thread Warner Losh
Author: imp
Date: Mon Jul  7 23:21:20 2014
New Revision: 268376
URL: http://svnweb.freebsd.org/changeset/base/268376

Log:
  rm -rf can fail sometimes with an error from fts_read. Make it honor
  fflag to ignore fts_read errors, but stop deleting from that directory
  because no further progress can be made.
  
  When building a kernel with a high -j value on a high core count
  machine, during the cleanobj phase we can wind up doing multiple rm
  -rf at the same time for modules that have subdirectories. This
  exposed this race (sometimes) as fts_read can return an error if the
  directory is removed by another rm -rf. Since the intent of the -f
  flag was to ignore errors, even if this was a bug in fts_read, we
  should ignore the error like we've been instructed to do.

svn commit: r268377 - head

2014-07-07 Thread Warner Losh
Author: imp
Date: Mon Jul  7 23:21:25 2014
New Revision: 268377
URL: http://svnweb.freebsd.org/changeset/base/268377

Log:
  xdev builds libsupc++ and libstdc++ in a slightly strange way. This
  cause a race to be exposed between the two. Compensate for this race
  by serializing the build/install of libstdc++ before libsupc++.
