netmap: monitor: add a flag to distinguish packet direction The netmap monitor intercepts any TX/RX packets on the monitored port. However, before this change there was no way to tell whether an intercepted packet was being transmitted or received on the monitored port. A TXMON flag in the netmap slot has been added for this purpose.

netmap: refactor logging macros and pipes Changelist: - Replace ND, D and RD macros with nm_prdis, nm_prinf, nm_prerr and nm_prlim, to avoid possible naming conflicts. - Add netmap_krings_mode_commit() helper function and use that to reduce code duplication. - Refactor pipes control code to export some functions that can be reused by the veth driver (on Linux) and epair(4). - Add check to reject API requests with version less than 11. - Small code refactoring for the null adapter.

netmap: align codebase to the current upstream (sha 8374e1a7e6941) Changelist: - Move large parts of VALE code to a new file and header netmap_bdg.[ch]. This is useful to reuse the code within upcoming projects. - Improvements and bug fixes to pipes and monitors. - Introduce nm_os_onattach(), nm_os_onenter() and nm_os_onexit() to handle differences between FreeBSD and Linux. - Introduce some new helper functions to handle more host rings and fake rings (netmap_all_rings(), netmap_real_rings(), ...) - Added new sysctl to enable/disable hw checksum in emulated netmap mode. - nm_inject: add support for NS_MOREFRAG Approved by: gnn (mentor) Differential Revision: https://reviews.freebsd.org/D17364

netmap: align codebase to the current upstream (commit id 3fb001303718146) Changelist: - Turn tx_rings and rx_rings arrays into arrays of pointers to kring structs. This patch includes fixes for ixv, ixl, ix, re, cxgbe, iflib, vtnet and ptnet drivers to cope with the change. - Generalize the nm_config() callback to accept a struct containing many parameters. - Introduce NKR_FAKERING to support buffers sharing (used for netmap pipes) - Improved API for external VALE modules. - Various bug fixes and improvements to the netmap memory allocator, including support for externally (userspace) allocated memory. - Refactoring of netmap pipes: now linked rings share the same netmap buffers, with a separate set of kring pointers (rhead, rcur, rtail). Buffer swapping does not need to happen anymore. - Large refactoring of the control API towards an extensible solution; the goal is to allow the addition of more commands and extension of existing ones (with new options) without the need of hacks or the risk of running out of configuration space. A new NIOCCTRL ioctl has been added to handle all the requests of the new control API, which cover all the functionalities so far supported. The netmap API bumps from 11 to 12 with this patch. Full backward compatibility is provided for the old control command (NIOCREGIF), by means of a new netmap_legacy module. Many parts of the old netmap.h header has now been moved to netmap_legacy.h (included by netmap.h). Approved by: hrs (mentor)

Import the current version of netmap, aligned with the one on github. This commit, long overdue, contains contributions in the last 2 years from Stefano Garzarella, Giuseppe Lettieri, Vincenzo Maffione, including: + fixes on monitor ports + the 'ptnet' virtual device driver, and ptnetmap backend, for high speed virtual passthrough on VMs (bhyve fixes in an upcoming commit) + improved emulated netmap mode + more robust error handling + removal of stale code + various fixes to code and documentation (some mixup between RX and TX parameters, and private and public variables) We also include an additional tool, nmreplay, which is functionally equivalent to tcpreplay but operating on netmap ports.

Sync netmap sources with the version in our private tree. This commit contains large contributions from Giuseppe Lettieri and Stefano Garzarella, is partly supported by grants from Verisign and Cisco, and brings in the following: - fix zerocopy monitor ports and introduce copying monitor ports (the latter are lower performance but give access to all traffic in parallel with the application) - exclusive open mode, useful to implement solutions that recover from crashes of the main netmap client (suggested by Patrick Kelsey) - revised memory allocator in preparation for the 'passthrough mode' (ptnetmap) recently presented at bsdcan. ptnetmap is described in S. Garzarella, G. Lettieri, L. Rizzo; Virtual device passthrough for high speed VM networking, ACM/IEEE ANCS 2015, Oakland (CA) May 2015 http://info.iet.unipi.it/~luigi/research.html - fix rx CRC handing on ixl - add module dependencies for netmap when building drivers as modules - minor simplifications to device-specific routines (*txsync, *rxsync) - general code cleanup (remove unused variables, introduce macros to access rings and remove duplicate code, Applications do not need to be recompiled, unless of course they want to use the new features (monitors and exclusive open). Those willing to try this code on stable/10 can just update the sys/dev/netmap/*, sys/net/netmap* with the version in HEAD and apply the small patches to individual device drivers. MFC after: 1 month Sponsored by: (partly) Verisign, Cisco

Update to the current version of netmap. Mostly bugfixes or features developed in the past 6 months, so this is a 10.1 candidate. Basically no user API changes (some bugfixes in sys/net/netmap_user.h). In detail: 1. netmap support for virtio-net, including in netmap mode. Under bhyve and with a netmap backend [2] we reach over 1Mpps with standard APIs (e.g. libpcap), and 5-8 Mpps in netmap mode. 2. (kernel) add support for multiple memory allocators, so we can better partition physical and virtual interfaces giving access to separate users. The most visible effect is one additional argument to the various kernel functions to compute buffer addresses. All netmap-supported drivers are affected, but changes are mechanical and trivial 3. (kernel) simplify the prototype for *txsync() and *rxsync() driver methods. All netmap drivers affected, changes mostly mechanical. 4. add support for netmap-monitor ports. Think of it as a mirroring port on a physical switch: a netmap monitor port replicates traffic present on the main port. Restrictions apply. Drive carefully. 5. if_lem.c: support for various paravirtualization features, experimental and disabled by default. Most of these are described in our ANCS'13 paper [1]. Paravirtualized support in netmap mode is new, and beats the numbers in the paper by a large factor (under qemu-kvm, we measured gues-host throughput up to 10-12 Mpps). A lot of refactoring and additional documentation in the files in sys/dev/netmap, but apart from #2 and #3 above, almost nothing of this stuff is visible to other kernel parts. Example programs in tools/tools/netmap have been updated with bugfixes and to support more of the existing features. This is meant to go into 10.1 so we plan an MFC before the Aug.22 deadline. A lot of this code has been contributed by my colleagues at UNIPI, including Giuseppe Lettieri, Vincenzo Maffione, Stefano Garzarella. MFC after: 3 days.
