* libnetmap: remove interface name validationVincenzo Maffione2024-09-011-5/+0
| | | | | | | | | | | | | | | | When trying to use a VLAN device (e.g. "em0.123") with a dot the library fails to parse the interface correctly. The former pattern is much too restrictive given that almost all characters can be coerced into a device name via ifconfig. Remove the particularly restrictive validation. Some characters still cannot be used as an interface name as they are used as delimiters in the syntax, but this allows to be able to use most of them without an issue.

* libnetmap: reset errno in nmreq_register_decode()Vincenzo Maffione2021-04-021-0/+2
| | | | | | | The reset is necessary at the beginning of the function, because of the errno logic in the error path (set errno to EINVAL if not set). If errno is already set when calling the function, and the function fails, the previous errno value will be inherited.

| | | | | | | | The companion libnetmap changes for the "offsets" kernel support added in a6d768d845c173823785c. This includes code to parse the "@offset=NNN" option that can be appended to the port name by any nmport_* application. Example: # pkt-gen -i 'netmap:em0@offset=16'

| | | | | | | | | | | | | | | Use uintptr_t to cast a uint64_t to a pointer type. Yeah, it isn't technically correct for platforms with pointers > 64 bits, but it's fine here.

* lib: add libnetmapVincenzo Maffione2020-08-286-0/+2328
This changeset introduces the new libnetmap library for writing netmap applications. Before libnetmap, applications could either use the kernel API directly (e.g. NIOCREGIF/NIOCCTRL) or the simple header-only-library netmap_user.h (e.g. nm_open(), nm_close(), nm_mmap() etc.) The new library offers more functionalities than netmap_user.h: - Support for complex netmap options, such as external memory allocators or per-buffer offsets. This opens the way to future extensions. - More flexibility in the netmap port bind options, such as non-numeric names for pipes, or the ability to specify the netmap allocator that must be used for a given port. - Automatic tracking of the netmap memory regions in use across the open ports. At the moment there is no man page, but the libnetmap.h header file has in-depth documentation.
