since bootst was written. Grab 3MB of the kernel image from tape
in hackprom_diskrd() instead of 2MB.
Bump bootst version on account of the above fix.
While here, use -Os instead of -O2 to compile mvme68k stand code.
than 32k.
A bootconf file is normally only a few hundred bytes long. If it is
much bigger than expected, we can't load it into an 8086 real mode
segment anyway.
Much more to the point, in the pxeboot case, someone may have
configured their dhcpd to return the filename for the kernel, not
realizing that the filename is now for boot.cfg which didn't used to
be the case. If we try to load the kernel here, thinking it is
boot.cfg by accident, the boot loader will die ignominiously and
without much of an error message, so we don't want to do that.
This needs to be pulled up to 5.0 if 5.0 has all this machinery
-- I'm not sure whether it does.
Fix some of the races (but probably not all of them) in the NFS server code.
nfssvc_nfsd(): change a splsoftclock()/spx() to mutex_enter/exit(&nfsd_lock)
(I guess it was forgotten when the nfsd code was made SMP safe)
m_freem(nd_nam) in nfsrv_slpderef() instead of nfsrv_zapsock() to
avoid possible use after free in nfssvc_nfsd()
Fix nfsrv_slpderef() to not release nfsd_lock before testing SLP_VALID
and reaquiring it just after. This could cause a use after free
of the slp if one thread is in nfsrv_slpderef() and the other one grabs
slp from nfssvc_sockpending and zap it.
nfsrv_rename() can exit without calling genfs_renamelock_exit() because
the nfsm_reply() can do return (0) on error.
Change nfsm_reply to use 'error = 0; goto nfsmout' instead.
Fix a few place so it's safe to goto nfsmout from nfsm_reply, or other
macros calling it.
As a side effect it could fix a missing vrele(dirp) in various place where
nfsm_reply could return(0).
