Adjust ccb and pdu counts to avoid ressource shortages. These are still

by using atomic operations.
- Assert kernel lock when calling into scsipi and network code.
- Use this to make send/receive/cleanup threads MPSAFE.
- Fix handling of out-of-CCB/out-of-PDU conditions against the scsipi layer.
- Bump number of PDUs to 128 to avoid virtually all out-of-PDU conditions
- Make use of softc structure for attach/detach operations.
- Track open file handles to prevent detach when busy.
- Move some global variables to make them static.
- Fix 'Overlapping Commands Attempted' error by marking commands as
simply ordered (ATTR_SIMPLE) like FreeBSD.

|
| 1.39 | 31-Mar-2022 |
pgoyette | For device modules that provide both auto-config and /dev/xxx
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).

Merge thorpej-cfargs branch:
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?).

pgoyette | Many years ago someone created a new __link_set_sysctl_funcs to hold
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.

- Protect lists and unique ids with mutexes. protect connection usecount
by using atomic operations.
- Assert kernel lock when calling into scsipi and network code.
- Use this to make send/receive/cleanup threads MPSAFE.
- Fix handling of out-of-CCB/out-of-PDU conditions against the scsipi layer.
- Bump number of PDUs to 128 to avoid virtually all out-of-PDU conditions
- Make use of softc structure for attach/detach operations.
- Track open file handles to prevent detach when busy.
- Move some global variables to make them static.
- Fix 'Overlapping Commands Attempted' error by marking commands as
simply ordered (ATTR_SIMPLE) like FreeBSD.

- Replace old tsleep/wakeup synchronization with mutexes and condvars.
- Defer actions from callouts (basically timeouts) to the cleanup thread.
- Protect lists and unique ids with mutexes. protect connection usecount
by using atomic operations.
- Assert kernel lock when calling into scsipi and network code.
- Use this to make send/receive/cleanup threads MPSAFE.
- Fix handling of out-of-CCB/out-of-PDU conditions against the scsipi layer.
- Bump number of PDUs to 128 to avoid virtually all out-of-PDU conditions
- Make use of softc structure for attach/detach operations.
- Track open file handles to prevent detach when busy.
- Move some global variables to make them static.
- Fix 'Overlapping Commands Attempted' error by marking commands as
simply ordered (ATTR_SIMPLE) like FreeBSD.

First, don't copy the head of a TAILQ to make a copy - the first entry will
still point back to the original head. This caused the ccb list to link to
itself, resulting in a continous loop processing the same ccb and blocked
interrupts. Use TAILQ_CONCAT() to copy the list.
Next, the ccb disposition was not set in the ccb when the ccb was throttled,
losing the CCBDISP_SCSIPI, so when a throttled ccb was resent, it failed to
call scscipi_done(), and left that I/O hanging.

Use correct status value SCSI_BUSY (0x08) instead of XS_BUSY (7) when
running out of sessions. The bug had no impact as scsipi was only comparing
against SCSI_CHECK (0x02) and SCSI_QUEUE_FULL (0x28).
Avoid race in timeout handling.
Don't try to wake up CCB without connection (which led to a NULL pointer
deref).

tls | branches: 1.3.2;
Separate /dev/random pseudodevice implemenation from kernel entropy pool
implementation. Rewrite pseudodevice code to use cprng_strong(9).
The new pseudodevice is cloning, so each caller gets bits from a stream
generated with its own key. Users of /dev/urandom get their generators
keyed on a "best effort" basis -- the kernel will rekey generators
whenever the entropy pool hits the high water mark -- while users of
/dev/random get their generators rekeyed every time key-length bits
are output.
The underlying cprng_strong API can use AES-256 or AES-128, but we use
AES-128 because of concerns about related-key attacks on AES-256. This
improves performance (and reduces entropy pool depletion) significantly
for users of /dev/urandom but does cause users of /dev/random to rekey
twice as often.
Also fixes various bugs (including some missing locking and a reseed-counter
overflow in the CTR_DRBG code) found while testing this.
For long reads, this generator is approximately 20 times as fast as the
old generator (dd with bs=64K yields 53MB/sec on 2Ghz Core2 instead of
2.5MB/sec) and also uses a separate mutex per instance so concurrency
is greatly improved. For reads of typical key sizes for modern
cryptosystems (16-32 bytes) performance is about the same as the old
code: a little better for 32 bytes, a little worse for 16 bytes.
