2023-03-04linux(4): Rename struct l_ifreq members names to avoid conflicts with FreeBSDDmitry Chagin
For now we are using mixed names to access struct ifreq members, some of Linux (ifr_name, ifr_ifindex), others of FreeBSD. To avoid conflicts switch to use FreeBSD names. Reviewed by: jhibbits Differential Revision: https://reviews.freebsd.org/D38792

2022-05-28linux(4): Handle SO_TIMESTAMPNS socket optionDmitry Chagin
The SO_TIMESTAMPNS enables or disables the receiving of the SCM_TIMESTAMPNS control message. The cmsg_data field is a struct timespec. To distinguish between SO_TIMESTAMP and SO_TIMESTAMPNS in the recvmsg() map the last one to the SO_BINTIME and convert bintime to the timespec. In the rest, implementation is identical to the SO_TIMESTAMP. MFC after: 2 weeks
2022-05-28linux(4): Handle 64-bit SO_TIMESTAMP for 32-bit binariesDmitry Chagin
To solve y2k38 problem in the recvmsg syscall the new SO_TIMESTAMP constant were added on v5.1 Linux kernel. So, old 32-bit binaries that knows only 32-bit time_t uses the old value of the constant, and binaries that knows 64-bit time_t uses the new constant. To determine what size of time_t type is expected by the user-space, store requested value (SO_TIMESTAMP) in the process emuldata structure. MFC after: 2 weeks

2020-11-08 - add more linux socket options (sorted by value)Alexander Leidinger
- map those IPv4 / IPv6 socket options which exist in FreeBSD + most of them visually verified to have the same type/layout of arguments + not tested with linux programs to behave as intended - be more human readable for known options which are not handled - be more verbose for unhandled socket message flags we know about - print the jail ID in linux_msg if run in a jail - add possibility to print debug message about known missing parts only once - add multiple levels of sysctl linux.debug: 1: print debug messages, tell about unimplemented stuff (only once) 2: like 1, but also print messages about implemented but not tested stuff (only once) 3+: like 2, but no rate limiting of messages - increase default linux debug level from 1 to 3 We are a lot more verbose in as we need to be (e.g. some of the IP socket options which are the same, and share the same memory layout, and are believed to work). The reason is that we have no good testsuite to test those linux-bits. The LTP or other test suites like the python one, are not fully up to the task we need. As such the excessive messages about emulated but not tested socket options. IMO any MFC (possible, but most probably not by me) should set the default debug level to 1.

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.

2017-11-27sys/compat: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
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=326266
