which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
Rework logic of gz_{un}compress to make it much less likely to leak fds
(at least 2 non-error paths leaked them!)
Make -S ".xyz" and -S "" both do something sensible.
Make in-situ compression work - only lose the file on error.
Pass an open fd to zopen (renamed zdopen) to avoid fd leakage (was badly borked)
Write header into first 64k output block to writes are aligned.
(more efficient and might avoid some problem with code that doesn't
like receiving partial buffers)
Check file size on compression - double checks against fs full.
Remove some pointless casts, and otherwise simplify some logic.
internally (shouldn't make a difference for callers)
-add convenience macros for config_found() and config_search() to
ease the case where just an interface attribute is specified
the diffs and possibly install the new version of file.
(Based on sshd_config munging code in do_ssh())
* Use modify_file() in do_hosts() and do_ssh().
* Be more specific in do_x11() about what needs to occur.
(This could still be improved).
* Minor sh cleanups. ("sh is not C")
- Clean up the namespace of this module and enable the encode/decode
functions and printing functions.
- Move the code that actually generates the UUID out of the system call
routine and into its own function.
com_mainbus_cninit() and move these cn functions from cobalt/console.c
to dev/com_mainbus.c
- call cninit() only once
- remove unneeded includes
- use ANSI function decls
grow-down auto extend segment) by allocating segment sized at
current stack size limit, and offsetting requested/returned address
as required
due to how normal virtual memory management work, allocating the
full sized stack memory segment up-front actually requires exactly same
amount of VA space and physical memory as the Linux 'grow' scheme and the
'grow' scheme is quite a lot more difficult to use in applications correctly,
so it's not very apparent why Linux introduced this feature at all
this fixes Thomas Klausner's Heroes3 crash, and might also
