2017-04-24Remove the NATM framework including the en(4), fatm(4), hatm(4), andBrooks Davis
patm(4) devices. Maintaining an address family and framework has real costs when we make infrastructure improvements. In the case of NATM we support no devices manufactured in the last 20 years and some will not even work in modern motherboards (some newer devices that patm(4) could be updated to support apparently exist, but we do not currently have support). With this change, support remains for some netgraph modules that don't require NATM support code. It is unclear if all these should remain, though ng_atmllc certainly stands alone. Note well: FreeBSD 11 supports NATM and will continue to do so until at least September 30, 2021. Improvements to the code in FreeBSD 11 are certainly welcome.

2016-04-21sys: use our roundup2/rounddown2() macros when param.h is available.Pedro F. Giffuni
rounddown2 tends to produce longer lines than the original code and when the code has a high indentation level it was not really advantageous to do the replacement. This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted. Notes: svn path=/head/; revision=298433
2015-01-05To ease changes to underlying mbuf structure and the mbuf allocator, reduceRobert Watson
the knowledge of mbuf layout, and in particular constants such as M_EXT, MLEN, MHLEN, and so on, in mbuf consumers by unifying various alignment utility functions (M_ALIGN(), MH_ALIGN(), MEXT_ALIGN() in a single M_ALIGN() macro, implemented by a now-inlined m_align() function: - Move m_align() from uipc_mbuf.c to mbuf.h; mark as __inline. - Reimplement M_ALIGN(), MH_ALIGN(), and MEXT_ALIGN() using m_align(). - Update consumers around the tree to simply use M_ALIGN(). This change eliminates a number of cases where mbuf consumers must be aware of whether or not mbufs returned by the allocator use external storage, but also assumptions about the size of the returned mbuf. This will make it easier to introduce changes in how we use external storage, as well as features such as variable-size mbufs.

2006-12-29Various bpf(4) related fixes to catch places up to the new bpf(4)John Baldwin
semantics. - Stop testing bpf pointers for NULL. In some cases use bpf_peers_present() and then call the function directly inside the conditional block instead of the macro. - For places where the entire conditional block is the macro, remove the test and make the macro unconditional. - Use BPF_MTAP() in if_pfsync on FreeBSD instead of an expanded version of the old semantics.

2005-09-19Make sure that we call if_free(ifp) after bus_teardown_intr. Since weWarner Losh
could get an interrupt after we free the ifp, and the interrupt handler depended on the ifp being still alive, this could, in theory, cause a crash. Eliminate this possibility by moving the if_free to after the bus_teardown_intr() call. Notes: svn path=/head/; revision=150306

2005-08-09Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE andRobert Watson
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

2005-06-10Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis
struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

2004-08-02* Add a "how" argument to uma_zone constructors and initialization functionsBrian Feldman
so that they know whether the allocation is supposed to be able to sleep or not. * Allow uma_zone constructors and initialation functions to return either success or error. Almost all of the ones in the tree currently return success unconditionally, but mbuf is a notable exception: the packet zone constructor wants to be able to fail if it cannot suballocate an mbuf cluster, and the mbuf allocators want to be able to fail in general in a MAC kernel if the MAC mbuf initializer fails. This fixes the panics people are seeing when they run out of memory for mbuf clusters. * Allow debug.nosleepwithlocks on WITNESS to be disabled, without changing the default.
