[CRYPTO] api: Feed flag directly to crypto_yield

The sleeping flag used to determine whether crypto_yield can actually
yield is really a per-operation flag rather than a per-tfm flag.  This
patch changes crypto_yield to take a flag directly so that we can start
using a per-operation flag instead the tfm flag.

13 years ago[CRYPTO] api: Added crypto_alloc_base
Herbert Xu [Sun, 30 Jul 2006 01:53:01 +0000]
[CRYPTO] api: Added crypto_alloc_base

Up until now all crypto transforms have been of the same type, struct
crypto_tfm, regardless of whether they are ciphers, digests, or other
types.  As a result of that, we check the types at run-time before
each crypto operation.

This is rather cumbersome.  We could instead use different C types for
each crypto type to ensure that the correct types are used at compile
time.  That is, we would have crypto_cipher/crypto_digest instead of
just crypto_tfm.  The appropriate type would then be required for the
actual operations such as crypto_digest_digest.

Now that we have the type/mask fields when looking up algorithms, it
is easy to request for an algorithm of the precise type that the user
wants.  However, crypto_alloc_tfm currently does not expose these new
attributes.

This patch introduces the function crypto_alloc_base which will carry
these new parameters.  It will be renamed to crypto_alloc_tfm once
all existing users have been converted.

Linus Torvalds [Tue, 19 Sep 2006 15:15:22 +0000]
Revert mmiocfg heuristics and blacklist changes

This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and
40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the
MMIO accesses for PCI config cycles even without the area being marked
reserved in the e820 memory tables.

Those changes were needed for EFI-environment Intel macs, but broke some
newer Intel 965 boards, so for now it's better to revert to our old
2.6.17 behaviour and at least avoid introducing any new breakage.

Andi Kleen has a set of patches that work with both EFI and the broken
Intel 965 boards, which will be applied once they get wider testing.

Ingo Molnar [Tue, 19 Sep 2006 09:14:34 +0000]
[PATCH] genirq core: fix handle_level_irq()

while porting the -rt tree to 2.6.18-rc7 i noticed the following
screaming-IRQ scenario on an SMP system:

 2274  0Dn.:1 0.001ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.010ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.020ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.029ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.039ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.048ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.058ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.068ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.077ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.087ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)
 2274  0Dn.:1 0.097ms: do_IRQ+0xc/0x103  <= (ret_from_intr+0x0/0xf)

as it turns out, the bug is caused by handle_level_irq(), which if it
races with another CPU already handling this IRQ, it _unmasks_ the IRQ
line on the way out. This is not how 2.6.17 works, and we introduced
this bug in one of the early genirq cleanups right before it went into
-mm. (the bug was not in the genirq patchset for a long time, and we
didnt notice the bug due to the lack of -rt rebase to the new genirq
code. -rt, and hardirq-preemption in particular opens up such races much
wider than anything else.)

This turns out to be a genuine bug.  The queue lock and xmit lock are
intentionally taken out of order.  Two things are supposed to prevent
dead-locks from occuring:

1) When we hold the queue_lock we're supposed to only do try_lock on the
tx_lock.

2) We always drop the queue_lock after taking the tx_lock and before doing
anything else.

This path obviously breaks assumption 1) and therefore can lead to ABBA
dead-locks.

I've looked at the history and there seems to be no reason for the lock
to be held at all in dev_watchdog_up.  The lock appeared in day one and
even there it was unnecessary.  In fact, people added __dev_watchdog_up
precisely in order to get around the tx lock there.

The function dev_watchdog_up is already serialised by rtnl_lock since
its only caller dev_activate is always called under it.

So here is a simple patch to remove the tx lock from dev_watchdog_up.
In 2.6.19 we can eliminate the unnecessary __dev_watchdog_up and
replace it with dev_watchdog_up.

From: Frank Pavlic <fpavlic@de.ibm.com>
        fixed kernel panic caused by qeth driver:
        Using a bonding device qeth driver will realloc
        headroom for every skb coming from the bond device.
        Once this happens qeth frees the original skb and
        set the skb pointer to the new realloced skb.
        Under heavy transmit workload (e.g.UDP streams) through bond
        network device the qdio output queue might get full.
        In this case we return with EBUSY from qeth_send_packet.
        Returning to qeth_hard_start_xmit routine
        the skb address on the stack still points to the old address,
        which has been freed before.
        Returning from qeth_hard_start_xmit with EBUSY results in
        requeuing the skb. In this case it corrupts the qdisc queue

David Woodhouse [Sat, 16 Sep 2006 19:15:55 +0000]
[PATCH] headers_check: use a different default directory

`make headers_check' wants to go and write stuff in /lib/modules, which
requires root, whic is unfortunate.

In fact, there's no _particular_ reason for headers_install to put it there
either -- it can go into a subdirectory of the build tree in both cases.
It's not intended to go directly into /usr/include, which is why we didn't
put it there -- and we certainly don't want people screwing around with
symlinking to it.  It's for distributors to take away and do stuff with, so
leaving it in $(objtree) is fine, even in the headers_install case.

I picked $(objtree)/usr/include but I have no _particular_ preference
for that; it just seemed reasonable.

[PATCH] Fix 'make headers_check' for Alpha

Alpha currently fails 'make headers_check' in the 2.6.18-rc kernels.  This
patch fixes it, by moving the existing #ifdef __KERNEL__ in asm/page.h so that
it covers everything that userspace shouldn't so, and by adding asm/compiler.h
to the list of exported files so that its use within asm/byteorder.h is
successful.

[ Note that at least with GCC 4, <linux/compiler.h> doesn't do the forced
  inlining about which there are nasty comments (and a workaround) in
  <asm/compiler.h>, unless you set CONFIG_FORCED_INLINING.  Rather than keep
  the mess you have in <asm/compiler.h> you could perhaps just make sure
  CONFIG_FORCED_INLINING=n is also honoured with GCC3, and make sure it cannot
  be set for Alpha? ]

Again, move stuff which shouldn't be visible inside (mostly already existing)
#ifdef __KERNEL__.

This fixes a bunch of mislabelled and unlabelled #endifs in unistd.h and also
cleans that up to conform with what's visible on other architectures, since
the minimal fix for the error reported about would have involved a more
intrusive patch, renesting other ifdefs.

[PATCH] Fix 'make headers_check' on i386

This brings i386 asm/unistd.h into consistency with other architectures by not
exporting functionality which is not necessary.

Hide parts which shouldn't be visible to userspace.

Move things around slightly so the right things end up within
#ifdef __KERNEL__ and thus don't pollute the exported headers.
