a data structure after it was freed. This wasn't actually a problem,
and the change caused the wrong pool_item_header to be freed
in the non-PR_PHINPAGE case.
in the air to deal with it.
Basically, following a kernel fault (eg. dereferencing a NULL pointer
in kernel mode) a DDB 'trace' did not show the function where the
fault occurred. For example:
db> trace
_Debugger()
_panic()
_trap()
faultstkadj()
_pool_drain()
_uvm_pageout()
_start_pagedaemon()
_proc_trampoline()
db>
The 'faultstkadj()' line here is bogus. It is shown because the return
address to 'trap()' happens to point there, and since faultstkadj() has
no stack frame, DDB assumes it was the faulting function. In this example,
the _real_ function was pool_reclaim(), but you would have to look at
the program counter at the time of the fault to figure that one out.
This fix makes the trace command do the dirty work for you by grubbing
around in 'trap()'s argument list to find the *real* PC value at the
time of the fault, replacing the 'faultstkadj()' line with the real
function's name.
It require "_crunch" section in /etc/man.conf to re-compress the compressed man pages.
It handle symbolic links, but at this time no hard links.
config files are stolen from man with few changes to support "_crunch" section.
catman.8 miss the "full moon" joke, I can't remember it, if you can pleas add it :-)
kernel per config file and the resulting kernel need not be named
"netbsd"; therefore paw through the config file after the kernel
builds are done, find them all, and put them where they belong per
release(7). This all done with some clever awk/sh scripting, from
PR 7180 by David Forbes.
* The MNT_UPDATE case had a null pointer dereference. (This is a good example
of why blindly adding bogus initializiers is a FUNDAMENTALLY BAD IDEA!)
* Make sure the whole ufsmount is zeroed, as the export code relies on this.
* If we decided to use the second/alternate superblock, make sure to copy the
in-core version from the right buffer.
Also, reenable NFS exporting.
