- add more linux socket options (sorted by value)

2020-11-08T09:50:58Z

- 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. Discussed with: trasz

Add compat.linux.dummy_rlimits, and disable by default.

Turns out the dummy rlimits fix prlimit(1), but break su(8) (login-1:4.5-1ubuntu2) - although not sudo(8), for some reason. MFC after: 2 weeks Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D26814

Set default stack size for Linux apps to 8MB. This matches Linux'

This is based on a patch submitted by Jason Yang, which I've reworked to set the limit instead of only changing the value reported (which is enough to fix the bug for Linux pthreads, but could be confusing).

linux: add sysctl compat.linux.use_emul_path

2020-08-18T22:04:22Z

This is a step towards facilitating jails with only Linux binaries. Supporting emul_path adds path lookups which are completely spurious if the binary at hand runs in a Linux-based root directory. It defaults to on (== current behavior). make -C /root/linux-5.3-rc8 -s -j 1 bzImage: use_emul_path=1: 101.65s user 68.68s system 100% cpu 2:49.62 total use_emul_path=0: 101.41s user 64.32s system 100% cpu 2:45.02 total
