* 1. Fix the handling of link reset while in netmap more.Luigi Rizzo2011-12-051-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A link reset now is completely transparent for the netmap client: even if the NIC resets its own ring (e.g. restarting from 0), the client will not see any change in the current rx/tx positions, because the driver will keep track of the offset between the two. 2. make the device-specific code more uniform across different drivers There were some inconsistencies in the implementation of the netmap support routines, now drivers have been aligned to a common code structure. 3. import netmap support for ixgbe . This is implemented as a very small patch for ixgbe.c (233 lines, 11 chunks, mostly comments: in total the patch has only 54 lines of new code) , as most of the code is in an external file sys/dev/netmap/ixgbe_netmap.h , following some initial comments from Jack Vogel about making changes less intrusive. (Note, i have emailed Jack multiple times asking if he had comments on this structure of the code; i got no reply so i assume he is fine with it). Support for other drivers (em, lem, re, igb) will come later. "ixgbe" is now the reference driver for netmap support. Both the external file (sys/dev/netmap/ixgbe_netmap.h) and the device-specific patches (in sys/dev/ixgbe/ixgbe.c) are heavily commented and should serve as a reference for other device drivers. Tested on i386 and amd64 with the pkt-gen program in tools/tools/netmap, the sender does 14.88 Mpps at 1050 Mhz and 14.2 Mpps at 900 MHz on an i7-860 with 4 cores and 82599 card. Haven't tried yet more aggressive optimizations such as adding 'prefetch' instructions in the time-critical parts of the code. Notes: svn path=/head/; revision=228276

* Support domain-search in dhclient(8)Jean-Sébastien Pédron2011-12-044-1/+405
| | | | | | | | | | | | | | | | | | | | | | | | The "domain-search" option (option 119) allows a DHCP server to publish a list of implicit domain suffixes used during name lookup. This option is described in RFC 3397. For instance, if the domain-search option says: ".example.org .example.com" and one wants to resolve "foobar", the resolver will try: 1. "foobar.example.org" 2. "foobar.example.com" The file /etc/resolv.conf is updated with a "search" directive if the DHCP server provides "domain-search". A regression test suite is included in this patch under tools/regression/sbin/dhclient. PR: bin/151940 Sponsored by Yakaz (http://www.yakaz.com) Notes: svn path=/head/; revision=228259

* Bring in support for netmap, a framework for very efficient packetLuigi Rizzo2011-11-177-0/+2294
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I/O from userspace, capable of line rate at 10G, see http://info.iet.unipi.it/~luigi/netmap/ At this time I am bringing in only the generic code (sys/dev/netmap/ plus two headers under sys/net/), and some sample applications in tools/tools/netmap. There is also a manpage in share/man/man4 [1] In order to make use of the framework you need to build a kernel with "device netmap", and patch individual drivers with the code that you can find in sys/dev/netmap/head.diff The file will go away as the relevant pieces are committed to the various device drivers, which should happen in a few days after talking to the driver maintainers. Netmap support is available at the moment for Intel 10G and 1G cards (ixgbe, em/lem/igb), and for the Realtek 1G card ("re"). I have partial patches for "bge" and am starting to work on "cxgbe". Hopefully changes are trivial enough so interested third parties can submit their patches. Interested people can contact me for advice on how to add netmap support to specific devices. CREDITS: Netmap has been developed by Luigi Rizzo and other collaborators at the Universita` di Pisa, and supported by EU project CHANGE (http://www.change-project.eu/) The code is distributed under a BSD Copyright. [1] In my opinion is a bad idea to have all manpage in one directory. We should place kernel documentation in the same dir that contains the code, which would make it much simpler to keep doc and code in sync, reduce the clutter in share/man/ and incidentally is the policy used for all of userspace code. Makefiles and doc tools can be trivially adjusted to find the manpages in the relevant subdirs. Notes: svn path=/head/; revision=227614
* LLVM uses atomic operations, which are not supported on i386 and GCCDimitry Andric2011-11-152-0/+60
| | | | | | | | | | | | | | emits calls for them, rather than expanding them inline. Older FreeBSD versions compile for i386 by default and as such we end up with unresolved symbols when we build LLVM's TableGen utility as a build tool on them. Add the functions that GCC emits here, but don't bother to make them atomic. Such is not needed. Submitted by: marcel MFC after: 1 week Notes: svn path=/head/; revision=227538

* Because ZFS boot code was very fragile in the past and real PITA to debug,Pawel Jakub Dawidek2011-10-212-0/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | introduce zfsboottest.sh script that will verify if it will be possible to boot from the given pool. # zfsboottest.sh system Where "system" is pool name of the pool we want to boot from. What is being verified by the script: - Does the pool exist? - Does it have bootfs property configured? - Is mountpoint property of the boot dataset set to 'legacy'? Dataset configured in bootfs property has to be mounted to perform more checks: - Does the /boot directory in boot dataset exist? - Is this dataset configured as root file system in /etc/fstab or set in vfs.root.mountfrom variable in /boot/loader.conf? By using zfsboottest tool the script will read all the files in /boot directory using ZFS boot code and calculate their checksums. Then, it will walk /boot directory using find(1) though regular file sytem and also read all the files in /boot directory and calculate their checksums. If any of the files cannot be looked up, read or checksum is invalid it will be reported and booting off of this pool is probably not possible. Some additional checks may be interesting as well. For example if the disks contain proper pmbr and gptzfsboot code or if all expected files in /boot/ are present. When upgrading FreeBSD, one should snapshot datasets that contain operating system, upgrade (install new world and kernel) and use zfsboottest.sh to verify if it will be possible to boot from new configuration. If all is good one should upgrade boot blocks, by eg.: # gpart -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1 If something is wrong, one should rollback datasets and report the problems.

* Second-to-last commit implementing Capsicum capabilities in the FreeBSDRobert Watson2011-08-112-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel for FreeBSD 9.0: Add a new capability mask argument to fget(9) and friends, allowing system call code to declare what capabilities are required when an integer file descriptor is converted into an in-kernel struct file *. With options CAPABILITIES compiled into the kernel, this enforces capability protection; without, this change is effectively a no-op. Some cases require special handling, such as mmap(2), which must preserve information about the maximum rights at the time of mapping in the memory map so that they can later be enforced in mprotect(2) -- this is done by narrowing the rights in the existing max_protection field used for similar purposes with file permissions. In namei(9), we assert that the code is not reached from within capability mode, as we're not yet ready to enforce namespace capabilities there. This will follow in a later commit. Update two capability names: CAP_EVENT and CAP_KEVENT become CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they represent.
