* Use compat.linux.emul_path instead of hardcoded path in /etc/rc.d/linuxEdward Tomasz Napierala2021-02-021-5/+5
| | | | | | | | | | | In /etc/rc.d/linux the mounting paths of procfs, sysfs and devfs are hardcoded to "/compat/linux". Switching to the content of compat.linux.emul_path sysctl would allow to switch linuxulator to different place.

* rtld: Fix null-pointer dereferenceDavid Chisnall2021-02-021-2/+4
| | | | | | | | | | | When a library is opened via fdlopen, it has a null pointer for its path and so _rtld_bind can crash as a result of passing the null pointer to basename() (which passes it to strrchr(), which doesn't do a null check).

* Remove dependency on files in /usr/binStefan Eßer2021-01-191-5/+12
| | | | | | | | | | | | | | | | | | | | | In order to reduce the pre-requisites of this file, implement the pattern matching and creation of a temporary test directory without use of grep respectively mktemp. The new version makes it possible to provide a writable /tmp in any case and independently of other local or remote file systems (except / and /dev) being mounted. The use of "dd if=/dev/random" has the same dependency on /dev/random being operational as the previous version that used "mktemp". If this is found to be an issue on platforms that do not have gathered sufficient entropy at the time when this scriot is run, I suggest to replace the "dd" command with "ps lauxww" to get a somewhat random test directory name.

* rtld-elf: link libcompiler_rt on all architecturesRyan Libby2020-12-283-17/+8
| | | | | | | | | | | | | | | | | | | | | Statically link rtld-elf with libcompiler_rt on all architectures so that we don't need to try to pick and choose the bits we need from it for each architecture (we now leave that to the linker). Compilers may emit calls to support functions in this library, but because of the use of the linker flag -nostdlib for rtld's special needs, the library is not linked as normal. Previously we had two different solutions. On some architectures, we were able to extract reimplementations of the necessary builtin functions from our special build of libc. On ARM, we just linked libcompiler_rt. This is motivated by the same issue as D26199 and D27665, but should be a simpler solution that will apply to all architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the gcc9 build of rtld-elf32 on amd64, which needed an implementation of udivmoddi4. rtld-elf uses certain functions normally found in libc, and so it includes certain files from libc in its own build. It has two mechanisms to include files from libc: one that rebuilds source files in the rtld-elf environment, and one that extracts object files from a purpose-built no-SSP PIC archive. In addition to libc functions, rtld-elf may need to link functions normally found in libcompiler_rt (formerly libgcc). Now, add an ability to rebuild libcompiler_rt source files in the rtld-elf environment. We don't yet have a need for an object file extraction mechanism. libcompiler_rt could also supply udivdi3 and umoddi3, but leave them alone for now.

The case of a separately mounted remote /usr file system (such as NFS) is still broken, but there is no obvious solution for that. Adding mountcritremote would fix the problem, but it would cause a POLA violation, because all kerberized NFS mounts in /etc/fstab would need the "late" option specified to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that Without walling /etc/rc.d/zfs on shutdown, resources associated with ZFS mounts are not freed and the jails will remain in dying state. In addition, the dataset is now in a dangling state, as the jail it is attached to is dying. A known workaround for jails was to add the following lines to /etc/jail.conf, to make sure that "service zfs stop" is run when the jail is stopped: exec.stop = "/bin/sh /etc/rc.shutdown"; exec.stop += "/usr/sbin/service zfs stop || /usr/bin/true"; While the workaround seems to be okay-ish for the jail situation, it is still unclean. However, for physical hosts this may wreak havoc with the pool if shared spares are used, as "zfs unshare" is never invoked on shutdown.

By default, the bootonce setting is reset on attempt to boot and the next boot will use previously active BE. By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will be set permanently active. bootonce dataset name is recorded in boot pool labels, bootenv area. in case of nextboot, the nextboot_enable boolean variable is recorded in freebsd:nvstore nvlist, also stored in boot pool label bootenv area. On boot, the loader will process /boot/nextboot.conf if nextboot_enable is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf processing on next boot. bootonce and nextboot features are usable in both UEFI and BIOS boot. To use bootonce/nextboot features, the boot loader needs to be updated on disk; if loader.efi is stored on ESP, then ESP needs to be updated and for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated (gpart or other tools).
