2023-10-13netlink: move NETLINK define to opt_global.hKristof Provost
Move the NETLINK define into opt_global.h so we can rely on it being set correctly, without having to remember to include opt_netlink.h. This ensures that the NETLINK define is correctly set. If not we may end up with unloadable modules, due to missing symbols (such as nlmsg_get_group_writer).

2022-10-01linuxolator: add netlink supportAlexander V. Chernikov
Add the glue code to support netlink in Linuxolator. linux_common(4) now depends on netlink(4). All netlink protocol constants are consistent with the Linux version. However, certain OS-specific constants such as AF_INET6, interface flags or default routing table id, are different between FreeBSD and Linux. Thus, it may be needed to rewrite some message parts or even rewrite the whole message, adding or removing some TLVs. The core netlink implementation code provides efficient rewriting callbacks which Linuxolator now uses.

2019-05-13Linuxulator depends on a fundamental kernel settings such as SMP. ManyDmitry Chagin
of them listed in opt_global.h which is not generated while building modules outside of a kernel and such modules never match real cofigured kernel. So, we should prevent our users from building obviously defective modules. Therefore, remove the root cause of the building of modules outside of a kernel - the possibility of building modules with DEBUG or KTR flags. And remove all of DEBUG printfs as it is incomplete and in threaded programms not informative, also a half of system call does not have DEBUG printf. For debuging Linux programms we have dtrace, ktr and ktrace ability.

2019-05-13Our bsd_to_linux_sockaddr() and linux_to_bsd_sockaddr() functionsDmitry Chagin
alter the userspace sockaddr to convert the format between linux and BSD versions. That's the minimum 3 of copyin/copyout operations for one syscall. Also some syscall uses linux_sa_put() and linux_getsockaddr() when load sockaddr to userspace or from userspace accordingly. To avoid this chaos, especially converting sockaddr in the userspace, rewrite these 4 functions to convert sockaddr only in kernel and leave only 2 of this functions. Also in order to reduce duplication between MD parts of the Linuxulator put struct sockaddr conversion functions that are MI out into linux_common module.

2018-04-06Move most of the contents of opt_compat.h to opt_global.h.Brooks Davis
opt_compat.h is mentioned in nearly 180 files. In-progress network driver compabibility improvements may add over 100 more so this is closer to "just about everywhere" than "only some files" per the guidance in sys/conf/options. Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h is created on all architectures. Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the set of compiled files.

2018-03-16Share a single bsd-linux errno table across MD consumersEd Maste
Three copies of the linuxulator linux_sysvec.c contained identical BSD to Linux errno translation tables, and future work to support other architectures will also use the same table. Move the table to a common file to be used by all. Make it 'const int' to place it in .rodata. (Some existing Linux architectures use MD errno values, but x86 and Arm share the generic set.) This change should introduce no functional change; a followup will add missing errno values. MFC after: 3 weeks Sponsored by: Turing Robotic Industries Inc.

Currently linux_common.ko incorporates a code from linux_mib.c and linux_util.c and linprocfs, linsysfs and linux kernel modules depend on linux_common.ko.
