* bpf: Add IfAPI analogue for bpf_peers_present()Justin Hibbits2023-10-131-1/+1
| | | | | | | | | | | | An interface's bpf could feasibly not exist, in which case bpf_peers_present() would panic from a NULL pointer dereference. Solve this by adding a new IfAPI that could deal with a NULL bpf, if such could occur in the network stack. Reviewed by: zlei Sponsored by: Juniper Networks, Inc.

* bpf: Add IfAPI analogue for bpf_peers_present()Justin Hibbits2023-10-131-1/+1
| | | | | | | | | | | An interface's bpf could feasibly not exist, in which case bpf_peers_present() would panic from a NULL pointer dereference. Solve this by adding a new IfAPI that includes a NULL check. Since this API is used in only a handful of locations, it reduces the the NULL check scope over inserting the check into bpf_peers_present(). Sponsored by: Juniper Networks, Inc. MFC after: 1 week

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-272-0/+4
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson2015-01-061-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.

| | | | | | | | | | | | | | | | | | | | | | | 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.
