It also prevents a buffer overflow if getrlimit should fail. Also replace per-fd condvars with mutexes to simplify the code.

This patch separates out the non-vnet'd initializations into a separate function invoked by SYSINIT(). This avoids use of IS_DEFAULT_VNET() in the initialization functions and also configures the non-vnet'd initialization function to be called first, although ordering is not currently needed.

As such, for kernels built with the VIMAGE option will malloc data and initialize locks on a per-vnet basis, typically via a VNET_SYSINIT(). This patch adds VNET_SYSUNINIT() macros to do the frees of the per-vnet malloc'd data and destroys of per-vnet locks. It also removes the mtx_lock/mtx_unlock calls from nfsrvd_cleancache(), since they are not needed. (cherry picked from commit ef6fcc5e2b0714c859d2e4ba23a55b1fd12f8a4e) 2023-05-18T22:59:27Z Rick Macklem rmacklem@FreeBSD.org 2023-02-18T22:59:36Z urn:sha1:56b45bf5f6e14f9a46ee896543ad24070f11cc9c Several commits have added front end macros for the vnet macros to the NFS server, krpc and kgssapi. These macros are now null, but this patch changes them to front end the vnet macros. With this commit, many global variables in the code become vnet'd, so that nfsd(8), nfsuserd(8), rpc.tlsservd(8) and gssd(8) can run in a vnet prison, once enabled. To run the NFS server in a vnet prison still requires a couple of patches (in D37741 and D38371) that allow mountd(8) to export file systems from within a vnet prison. Once these are committed to main, a small patch to kern_jail.c allowing "allow.nfsd" without VNET_NFSD defined will allow the NFS server to run in a vnet prison. One area that still needs to be settled is cleanup when a prison is removed. Without this, everything should work except there will be a leak of malloc'd data and mutex locks when a vnet prison is removed.
