rwatson 2001/12/03 08:12:28 PST Modified files: sys/compat/linprocfs linprocfs.c sys/compat/linux linux_mib.c linux_mib.h linux_misc.c sys/fs/procfs procfs_status.c sys/kern kern_jail.c kern_mib.c kern_prot.c sys/netinet in_pcb.c sys/sys jail.h Log: o Introduce pr_mtx into struct prison, providing protection for the mutable contents of struct prison (hostname, securelevel, refcount, pr_linux, ...) o Generally introduce mtx_lock()/mtx_unlock() calls throughout kern/ so as to enforce these protections, in particular, in kern_mib.c protection sysctl access to the hostname and securelevel, as well as kern_prot.c access to the securelevel for access control purposes. o Rewrite linux emulator abstractions for accessing per-jail linux mib entries (osname, osrelease, osversion) so that they don't return a pointer to the text in the struct linux_prison, rather, a copy to an array passed into the calls. Likewise, update linprocfs to use these primitives. o Update in_pcb.c to always use prison_getip() rather than directly accessing struct prison.
