rtld-elf: link udivmoddi4 from compiler_rt

2020-12-19T08:38:31Z

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.

rtld-libc: fix incremental build

2020-12-19T08:38:27Z

ar cr is an update of an archive, not a creation of a new one. During incremental builds (e.g. with meta mode) the archive was not getting cleaned, and so could retain now-deleted objects from previous builds. Now, delete the archive before creating/updating it.

Make mountcritremote dependent upon nfscbd.

2020-12-17T00:20:57Z

Although it is not often needed, the nfscbd(8) should be running when NFSv4 mounts are done if callback functionality is required. Callback functionality is required for the NFSv4 server to issue delegations or pNFS layouts. This patch adds nfscbd to the mountcritremote's REQUIRED line to ensure it is started before NFS mounts specified in /etc/fstab are done.

Add CFI start/end proc directives to arm64, i386, and ppc

Follow-up to r353959 and r368070: do the same for other architectures. arm32 already seems to use its own .fnstart/.fnend directives, which appear to be ARM-specific variants of the same thing. Likewise, MIPS uses .frame directives. Reviewed by: arichardson Differential Revision: https://reviews.freebsd.org/D27387

Revert r366857.

2020-12-04T19:31:16Z

r366857 created a number of problems, tearing down interfaces too early in shutdown. This resulted in: - hung ssh sessions when shutting down or rebooting remotely using shutdown (I've used exec shutdown, for years, as apposed to simply shutdown). - NFS mounted filesystems "disappear" prior to unmount. - dhclient attached to a VLAN on an interface who's parent interface has already shut down prints errors. The path forward is to teach lagg(4) and vlan(4) about WOL.
