Fix negotiation for mutual authentication.
Prepare for more CHAP types.
Fix crashes for invalid socket descriptors passed to kernel.
Protect usecount with connection mutex, avoids race on connection close.
Minor cosmetics.
protect network socket with rwlock to handle recconnects.
always take over socket from iscsid to prevent leaks.
keep a good connection alive.
don't forget child device when config_detach fails.
fix locking when reassigning CCBs.
pducount is protected by lock, no need for atomic.
some code rework, refined debug messages.
interfaces, make sure that initialization and destruction
follow the proper sequence. This is triggered by the recent
changes to the devsw stuff; per riastradh@ the required call
sequence is:
devsw_attach()
config_init_component() or config_cf*_attach()
...
config_fini_component() or config_cf*_detach()
devsw_detach()
While here, add a few missing calls to some of the detach
routines.
Testing of these changes has been limited to:
1. compile without build break
2. no related test failures from atf
3. modload/modunload work as well as
before.
No functional device testing done, since I don't have any
of these devices. Let me know of any damage I might cause
here!
XXX Some of the modules affected by this commit are already
XXX broken; see kern/56772. This commit does not break
any additional modules (as far as I know).
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
Use the dedicated reference counting routines.
Change the type of struct vmspace::vm_refcnt and struct vm_map::ref_count
to volatile.
Remove the unnecessary vm->vm_map.misc_lock locking in process_domem().

the list of routines that need to be called for setting up sysctl
variables. This worked great for all code included in the kernel
itself, but didn't deal with modules that want to create their own
sysctl data. So, we ended up with a lot of #ifdef _MODULE blocks
so modules could explicitly call their setup functions when loaded
as non-built-in modules.
So today, we complete the task that was started so many years ago.
When modules are loaded, after we've called xxx_modcmd(INIT...) we
check if the module contains its own __link_set_sysctl_funcs, and
if so we call the functions listed. We add a struct sysctllog member
to the struct module so we can call sysctl_teardown() when the module
gets unloaded. (The sequence of events ensures that the sysctl stuff
doesn't get created until the rest of the module's init code does any
required memory allocation.)
So, no more need to explicitly call the sysctl setup routines when
built as a loadable module.
and retry the command. Start with a small openings number and let scsipi
request to grow it up to the current send window.
Adjust ccb and pdu counts to avoid ressource shortages. These are still
very ad-hoc numbers, but seem to be sufficient for a Gigabit link.
Use separate condvar for PDU pool and add counter to help debugging.
Revert setting PDU disposition to UNUSED before freeing. free_pdu
uses this as a flag to detect already returned PDUs.
Add reference counter for open commands to defer unmapping a session
that would lead to crashes in scsipi.
Move session cleanup to cleanup thread.
Use get_sernum to retrieve current serial number where possible and
make it check for immediate commands itself.
Adjust debug output.
