riastradh | opencrypto: Fix typo that somehow snuck past our resident typo-hunter.

(as in assembly).

riastradh | opencrypto: crypto_dispatch never fails now. Make it return void.
Same with crypto_kdispatch.
|

| 22-May-2022 |
riastradh | opencrypto: Rip out EAGAIN logic when unregistering crypto drivers.
I'm pretty sure this never worked reliably based on code inspection,
and it's unlikely to have ever been tested because it only applies
when unregistering a driver -- but we have no crypto drivers for
removable devices, so it would only apply if we went out of our way
to trigger detach with drvctl.
Instead, just make the operation fail with ENODEV, and remove all the
callback logic to resubmit the request on EAGAIN. (Maybe this should
be ENXIO, but crypto_kdispatch already does ENODEV.)

riastradh | crypto(4): Nix dead code now that crypto_freesession never fails.
|
| 1.120 |
| 22-May-2022 |
riastradh | opencrypto: Make crypto_freesession return void.
No callers use the return value. It is not sensible to allow this to
fail.
|
| 1.119 |
| 22-May-2022 |
riastradh | crypto(4): crypto_freesession should never fail here.
It can only fail if we pass it an invalid sid, which the logic to
maintain the user sessions should not do. So kassert error=0 here.
|
| 1.118 |
| 22-May-2022 |
riastradh | crypto(4): Refuse crypto operations with nothing in them earlier.
This way we avoid passing 0 to crypto_getreq -- makes it easier to
reason about everything downstream.
|
| 1.117 |
| 22-May-2022 |
riastradh | opencrypto: Make crp_callback, krp_callback return void.
Nothing uses the return values inside opencrypto, so let's stop
making users return them.
|
| 1.116 |
| 22-May-2022 |
riastradh | crypto(4): Fix possible use-after-free in race around detach.
This is extremely unlikely because I don't think we have any drivers
for removable crypto decelerators^Waccelerators...but if we were to
sprout one, and someone ran crypto_dispatch concurrently with
crypto_unregister, cryptodev_cb/mcb would enter with crp->crp_etype =
EAGAIN and with CRYPTO_F_DONE set in crp->crp_flags. In this case,
cryptodev_cb/mcb would issue crypto_dispatch but -- since nothing
clears CRYPTO_F_DONE -- it would _also_ consider the request done and
notify the ioctl thread of that.
With this change, we return early if crypto_dispatch succeeds. No
need to consult CRYPTO_F_DONE: if the callback is invoked it's done,
and if we try to redispatch it on EAGAIN but crypto_dispatch fails,
it's done. (Soon we'll get rid of the possibility of crypto_dispatch
failing synchronously, but not just yet.)
XXX This path could really use some testing!
|
| 1.115 |
| 21-May-2022 |
riastradh | crypto(4): Fix set-but-unused variable warning.
This deliberately ignores the error code returned by crypto_dispatch,
but that error code is fundamentally incoherent and the issue will be
mooted by subsequent changes to make it return void and always pass
the error through the callback, as well as subsequent changes to rip
out the EAGAIN logic anyway.
|
| 1.114 |
| 21-May-2022 |
riastradh | crypto(4): Don't signal the condvar for multi-operation completion.
The condvar may be destroyed by the time we got here, and nothing
waits on it anyway -- instead the caller is expected to select/poll
for completion in userland.
The bug was already here, but the recent change to eliminate
CRYPTO_F_CBIMM made it happen more often by causing the callback to
_always_ be run asynchronously instead of sometimes being run
synchronously.
|
| 1.113 |
| 19-May-2022 |
riastradh | opencrypto: Nix CRYPTO_F_USER, CRYPTO_F_CBIMM, CRYPTO_F_CBIFSYNC.
CRYPTO_F_USER is no longer needed. It was introduced in 2008 by
darran@ in crypto.c 1.30, cryptodev.c 1.45 in an attempt to avoid
double-free between the issuing thread and asynchronous callback.
But the `fix' didn't work. In 2017, knakahara@ fixed it properly in
cryptodev.c 1.87 by distinguishing `the crypto operation has
completed' (CRYPTO_F_DONE) from `the callback is done touching the
crp object' (CRYPTO_F_DQRETQ, now renamed to CRYPTODEV_F_RET).
CRYPTO_F_CBIMM formerly served to invoke the callback synchronously
from the driver's interrupt completion routine, to reduce contention
on what was once a single cryptoret thread. Now, there is a per-CPU
queue and softint for much cheaper processing, so there is less
motivation for this in the first place. So let's remove the
complicated logic. This means the callbacks never run in hard
interrupt context, which means we don't need to worry about recursion
into crypto_dispatch in hard interrupt context.

|

riastradh | crypto(4): Narrow scope of cryptodev_mtx to cover wait.
No functional change intended -- this only removes an unnecessary
lock/unlock cycle in the error case.

riastradh | crypto(4): Nix long-dead code and comments.
|
| 1.109 |
| 18-May-2022 |
riastradh | crypto(4): Use IPL_NONE, not IPL_NET, for /dev/crypto pools.
These are used (pool_get/put) only from thread context, never from
interrupt or even soft interrupt context.
|
| 1.108 |
| 17-May-2022 |
riastradh | opencrypto(9): Omit needless casts around callbacks.
Just declare the right types to begin with. No functional change
intended.
|
| 1.107 |
| 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).

chs | slightly change and fix the semantics of pool_set*wat(), pool_sethardlimit()
and pool_prime() (and their pool_cache_* counterparts):
- the pool_set*wat() APIs are supposed to specify thresholds for the count of
free items in the pool before pool pages are automatically allocated or freed
during pool_get() / pool_put(), whereas pool_sethardlimit() and pool_prime()
are supposed to specify minimum and maximum numbers of total items
in the pool (both free and allocated). these were somewhat conflated
in the existing code, so separate them as they were intended.
- change pool_prime() to take an absolute number of items to preallocate
rather than an increment over whatever was done before, and wait for
any memory allocations to succeed. since pool_prime() can no longer fail
after this, change its return value to void and adjust all callers.
- pool_setlowat() is documented as not immediately attempting to allocate
any memory, but it was changed some time ago to immediately try to allocate
up to the lowat level, so just fix the manpage to describe the current
behaviour.
- add a pool_cache_prime() to complete the API set.

knakahara | fix race among crypto_done(), cryptoret(), and {cryptodev_op(), cryptodev_key()}.
crypto_op() waited to be set CRYPTO_F_DONE with crp->crp_cv.
However, there is context switch chances between being set CRYPTO_F_DONE in
crypto_done() and done cv_signal(crp->crp_cv) in cryptodev_cb(), that is,
cryptodev_op() thread can run to cv_destroy(crp->crp_cv) before cryptoret()
thread is waken up. As a result, cryptodev_cb() can call invalid(destroyed)
cv_signal(crp->crp_cv).
Furthermore, below two implementations cause other races.
- waiting CRYPTO_F_DONE with crp->crp_cv
- context witch chances between set CRYPTO_F_DONE and cv_signal(crp->crp_cv)
So, use other flag(CRYPTO_F_DQRETQ) for cryptodev_op() and cryptodev_key(),
and then call cv_signal(crp->crp_cv) immediately after set CRYPTO_F_DQRETQ.
Tested concurrent over 20 processes with software and hardware drivers.

knakahara | fix processes accessing /dev/crypto stall when over three processes run with a hardware encryption driver
The process has stalled at cv_wait(&crp->crp_cv) because cryptodev_cb()
is not called as cryptoret() kthread keep waiting at cv_wait(&cryptoret_cv).
Previous opencrypto implementation assumes the thread from cryptodev.c
does all processing in the same context, so skips enqueueing and sending
cryptoret_cv. However, the context can be switched, e.g. when we use
a hardware encryption driver.
And add debug messages.

cryptodev.c which should be revisited)
The latter one seems to be uneeded at many places, but for now I've
done simple replacements only, except minor fixes (where
softint_schedule() was called without the lock held)

drochner | As a first step towards more fine-grained locking, don't require

dsl | If a multithreaded app closes an fd while another thread is blocked in
read/write/accept, then the expectation is that the blocked thread will

Since only one fd is affected, but many fd can refer to the same file,
the close code can only request the fs code unblock with ERESTART.
Fixed for pipes and sockets, ERESTART will only be generated after such
a close - so there should be no change for other programs.

Extends the Opencrypto API to allow the destination buffer size to be
specified when its not the same size as the input buffer (i.e. for
operations like compress and decompress).
The crypto_op and crypt_n_op structures gain a u_int dst_len field.
The session_op structure gains a comp_alg field to specify a compression
algorithm.
Moved four ioctls to new ids; CIOCGSESSION, CIOCNGSESSION, CIOCCRYPT,
and CIOCNCRYPTM.
Added four backward compatible ioctls; OCIOCGSESSION, OCIOCNGSESSION,
OCIOCCRYPT, and OCIOCNCRYPTM.
Backward compatibility is maintained in ocryptodev.h and ocryptodev.c which
implement the original ioctls and set dst_len and comp_alg to 0.
Adds user-space access to compression features.
Adds software gzip support (CRYPTO_GZIP_COMP).
Adds the fast version of crc32 from zlib to libkern. This should be generally
useful and provide a place to start normalizing the various crc32 routines
in the kernel. The crc32 routine is used in this patch to support GZIP.

Fix a race condition in opencrypto where the crypto request could be
completed by the crypto device, queued on the retq, but freed by the
ioctl lwp. The problem manifests as various panics relating to the
condvar inside the request. The problem can occur whenever the crypto
device completes the request immediately and the ioctl skips the cv_wait().
The problem can be reproduced by enabling cryptosoft and running an openssl
speed test. E.g.
sysctl -w kern.cryptodevallowsoft=-1
openssl speed -engine cryptodev -evp des-ede3-cbc -multi 64
Add a macro for TAILQ_FOREACH_REVERSE_SAFE() to queue.h, since this
was missing and the opencrypto code removes requests from a list while
iterating with TAILQ_FOREACH_REVERSE().
Add missing cv_destroy() calls for the key request cleanup.

* Mutliple-request submit/retrieve ioctls
* Mutliple-session create-destroy ioctls
Revise/rewrite crypto.4 manual page. It should now be much easier to write
new applications to this API.
Measured performance for trivial requests: 84,000 very short modular math
operations/sec, 120,000 very short md5 hashes per sec (with a hardware
accellerator of moderate performance but very low latency, whose driver
will be contributed at a later date).

Some locking fixes (double-release mutex in softintr wakeup case, which I
hadn't tested) and an uninitialized field in cse which Darran Hunt
found. Some more debugging printfs.
Turn on MPSAFE for the kthread. We're not sure it's safe for the softint
yet. Gives a little performance kick for swcrypto with many requests on
MP systems.

tls | Rework opencrypto to use a spin mutex (crypto_mtx) instead of "splcrypto"
(actually splnet) and condvars instead of tsleep/wakeup. Fix a few
miscellaneous problems and add some debugging printfs while there.
Restore set of CRYPTO_F_DONE in crypto_done() which was lost at some
point after this code came from FreeBSD -- it made it impossible to wait
properly for a condition.
Add flags analogous to the "crp" flags to the key operation's krp struct.
Add a new flag, CRYPTO_F_ONRETQ which tells us a request finished before
the kthread had a chance to dequeue it and call its callback -- this was
letting requests stick on the queues before even though done and copied
out.
Callers of crypto_newsession() or crypto_freesession() must now take the
mutex. Change netipsec to do so. Dispatch takes the mutex itself as
needed.
This was tested fairly extensively with the cryptosoft backend and lightly
with a new hardware driver. It has not been tested with FAST_IPSEC; I am
unable to ascertain whether FAST_IPSEC currently works at all in our tree.
pjd@FreeBSD.ORG, ad@NetBSD.ORG, and darran@snark.us pointed me in the
right direction several times in the course of this. Remaining bugs
are mine alone.

mechanical changes that touch live source lines) -- try it and see.

tls | Some minor opencrypto fixes, one with a major performance impact for
OpenSSL:
1) Fix extremely misleading text in crypto.4 manual page so it does not
appear to claim that a new cloned file descriptor is required for every
session.
2) Fix severe performance problem (and fd leak!) in openssl cryptodev
engine resulting from misunderstanding probably caused by said manual
page text.
3) Check for session-ID wraparound in kernel cryptodev provider. Also,
start allocating sessions at 1, not 0 -- this will be necessary when
we add ioctls for the creation of multiple sessions at once, so we
can tell which if any creations failed.

jonathan | Clean up userlevel access to software kernel transforms, in preparation
for using /dev/crypto for OpenSSL:
1. Add comments explaining crypto_devallowsoft, explaining the
OpenBSD-style three-way logic actully implemented in crypto_newsession().
2. Pass crypto_devallowsoft as the final argument to crypto_newsession(),
instead of a constant 0 value.
3. Set the default value of crypto_devallowsoft to 1, to allow
/dev/crypto access only for hardware-supported transforms.
Items 1-3 may be revised to match the FreeBSD two-way logic, if the
consensus is that there's no point to forcing software transforms.
But as a first step, let the description match what the code actually does.
GC unused variables usercrypto, userasmcrypto, cryptodevallowsoft from
cryptodev.c, in favour of variables crypto_usercrypto, crypto_userasmcrypto,
crypto_devallowsoft, which are used as well as defined in crypto.c.

Fixes PR kern/41069 and PR kern/41070.
Extends the Opencrypto API to allow the destination buffer size to be
specified when its not the same size as the input buffer (i.e. for
operations like compress and decompress).
The crypto_op and crypt_n_op structures gain a u_int dst_len field.
The session_op structure gains a comp_alg field to specify a compression
algorithm.
Moved four ioctls to new ids; CIOCGSESSION, CIOCNGSESSION, CIOCCRYPT,
and CIOCNCRYPTM.
Added four backward compatible ioctls; OCIOCGSESSION, OCIOCNGSESSION,
OCIOCCRYPT, and OCIOCNCRYPTM.
Backward compatibility is maintained in ocryptodev.h and ocryptodev.c which
implement the original ioctls and set dst_len and comp_alg to 0.
Adds user-space access to compression features.
Adds software gzip support (CRYPTO_GZIP_COMP).
Adds the fast version of crc32 from zlib to libkern. This should be generally
useful and provide a place to start normalizing the various crc32 routines
in the kernel. The crc32 routine is used in this patch to support GZIP.
With input and support from tls@NetBSD.org.

sys/opencrypto/cryptodev.h: revision 1.15
sys/opencrypto/crypto.c: revision 1.30
Fix a race condition in opencrypto where the crypto request could be
completed by the crypto device, queued on the retq, but freed by the
ioctl lwp. The problem manifests as various panics relating to the
condvar inside the request. The problem can occur whenever the crypto
device completes the request immediately and the ioctl skips the
cv_wait().
The problem can be reproduced by enabling cryptosoft and running an
openssl
speed test. E.g.
sysctl -w kern.cryptodevallowsoft=-1
openssl speed -engine cryptodev -evp des-ede3-cbc -multi 64
Add a macro for TAILQ_FOREACH_REVERSE_SAFE() to queue.h, since this
was missing and the opencrypto code removes requests from a list while
iterating with TAILQ_FOREACH_REVERSE().
Add missing cv_destroy() calls for the key request cleanup.

pgoyette | Rename LOCALCOUNT_INITIALIZER to DEVSW_MODULE_INIT. This better describes
what we're doing, and why.
|
| 1.85.2.2 |
| 19-Jul-2016 |
pgoyette | Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.
As suggested by riastradh@
|
| 1.85.2.1 |
| 18-Jul-2016 |
pgoyette | Rump drivers are always installed via devsw_attach() so we need to
always allocate a 'struct localcount' for these drivers whenever they
are built as modules.

pgoyette | At suggestion of chuq@, modify config_attach_pseudo() to return with a
reference held on the device.
Adapt callers to expect the reference to exist, and to ensure that the
reference is released.

pgoyette | Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).
The branch now builds, and installs via anita. There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.

snj | Pull up following revision(s) (requested by knakahara in ticket #97):
sys/opencrypto/crypto.c: 1.87-1.91
sys/opencrypto/cryptodev.c: 1.93-1.95
sys/opencrypto/cryptodev.h: 1.37
sys/opencrypto/cryptosoft.c: 1.52
sys/rump/dev/lib/libopencrypto/opencrypto_component.c: 1.5
sanitize count used for kmem_alloc size.
Hmm, who uses CIOCNGSESSION, CIOCNFSESSION, CIOCNCRYPTM or CIOCNFKEYM?
--
sanitize in CIOCNCRYPTM and initialize comp_alg in CIOCNGSESSION
--
must release cap->cc_lock before calling cap->cc_newsession() because of spinlock.
--
refactor crypto_newsession() like FreeBSD.
--
support multiple encryption drivers (port from FreeBSD).
--
Divide crp_devflags from crp_flags to write exclusively.
CRYPTO_F_DQRETQ(new name is CRYPTODEV_F_RET) is used by cryptodev.c only.
It should be divided to other member.
--
Reduce crypto_ret_q_mtx lock regions.
crypto.c does not access the members of crp when the crp is in crp_q or
crp_ret_q. Furthermore, crp_q and crp_ret_q are protected by each mutex,
so the members of crp is not shared. That means crp_flags is not required
mutex in crypto.c.
--
fix cryptosoft.c:r1.51 mistake. swcrypto_attach() must not be called from module_init_class().
swcrypto_attach() will call softint_establish(), it must be called after cpus
attached. module_init_class() is too early to call softint_establish().
--
simplify mutex_enter/exit(crypto_q_mtx), and fix missing exit.
--
reduce rump waring message. pointed out by ozaki-r@n.o, thanks.

pgoyette | Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line
rather than defining an intermediate hook##call function. Almost
all of the hooks are called only once, and although we lose the
ability of doing things like
if (MODULE_HOOK_CALL(...) == 0) ...
we simplify things quite a bit. With this change, we no longer need
to have both declaration and definition macros, and the definition
no longer needs to have both prototype argument list and a "real"
argument list.
FWIW, the above if now needs to written as
int ret;
MODULE_HOOK_CALL(..., ret);
if (ret == 0) ...
with appropriate use of braces {}.
|
| 1.98.2.10 |
| 18-Jan-2019 |
pgoyette | Don't restrict hooks to having only int or void types. Pass the hook's
type to the various macros, as needed.
Allows us to reduce diffs to original in at least one or two places (we
no longer have to provide an additional parameter to the hook routine
for returning a non-int return value).
|
| 1.98.2.9 |
| 14-Jan-2019 |
pgoyette | Create a variant of the HOOK macros that handles hook routines of
type void, and use them where appropriate.
|
| 1.98.2.8 |
| 13-Jan-2019 |
pgoyette | Remove the HOOK2 versions of the MODULE_HOOK macros. There were
only a few uses, and using them led to some lack of clarity in the
code. Instead, we now use two separate hooks, with names that
make it clear(er) what we're doing.
This also positions us to start unraveling some of the rtsock_50
mess, which will need (at least) five hooks.
|
| 1.98.2.7 |
| 29-Sep-2018 |
pgoyette | In MODULE_HOOK_CALL_DECL we don't need to provide the actual argument
list for calling the hook function, nor do we need to provide the
default value (for when the hook has not been set).
|
| 1.98.2.6 |

pgoyette | Split the compat_crypto_50 from the rest of the crypto module
Cleanup some stuff left over from similar changes to raid modules.
|
| 1.98.2.5 |
| 22-Sep-2018 |
pgoyette | When the compat code needs to callback to the original code, we cannot
call directly via the routines' global symbols, since the original code
might not be built-in. So, the original code that calls compat code
needs to pass in the addresses of the callbacks. This allows for the
compat code to be built whether or not the original (calling) code is
included.
XXX Done for cryptodev, will need to do the same thing for ccd(4) and
XXX vnd(4)

| 1.98.2.4 |

pgoyette | The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
|
| 1.98.2.3 |
| 18-Sep-2018 |
pgoyette | Split the COMPAT_CALL_HOOK to separate the declaration from the
implementation. Some hooks are called from multiple source files,
and the old method resulted in duplicate implementations.
Implement MP-safe hooks for the usb_subr_30 code. Pass the helper
functions as arguments to the compat code so it does not have to
determine if the kernel contains usb code.
|
| 1.98.2.2 |
| 17-Sep-2018 |
pgoyette | Adapt (most of) the indirect function pointers to the new MP-safe
mechanism. Still remaining are the compat_netbsd32 stuff, and
some usb subroutines.
