Mike Christie [Thu, 26 Jul 2007 17:46:47 +0000]
[SCSI] iscsi_tcp: Turn off bounce buffers

It was found by LSI that on setups with large amounts of memory
we were bouncing buffers when we did not need to. If the iscsi tcp
code touches the data buffer (or a helper does),
it will kmap the buffer. iscsi_tcp also does not interact with hardware,
so it does not have any hw dma restrictions. This patch sets the bounce
buffer settings for our device queue so buffers should not be bounced
because of a driver limit.

9p: Don't use binary sysctl numbers.

The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.

And since it was only for debugging clearly did not need a binary fast
path in any case.  So this patch just remove the binary numbers.

See Documentation/sysctl/ctl_unnumbered.txt for more details.

While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.

12 years agox86: Replace NSC/Cyrix specific chipset access macros by inlined functions.
Juergen Beisert [Sun, 22 Jul 2007 09:12:38 +0000]
x86: Replace NSC/Cyrix specific chipset access macros by inlined functions.

Due to index register access ordering problems, when using macros a line
like this fails (and does nothing):

setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);

With inlined functions this line will work as expected.

Note about a side effect: Seems on Geode GX1 based systems the
"suspend on halt power saving feature" was never enabled due to this
wrong macro expansion. With inlined functions it will be enabled, but
this will stop the TSC when the CPU runs into a HLT instruction.
Kernel output something like this:
Clocksource tsc unstable (delta = -472746897 ns)

This is the 3rd version of this patch.

 - Adding missed arch/i386/kernel/cpu/mtrr/state.c

Add a general utility function to change write protected text.  The new

x86: i386-show-unhandled-signals-v3

This patch makes the i386 behave the same way that x86_64 does when a
segfault happens.  A line gets printed to the kernel log so that tools
that need to check for failures can behave more uniformly between
debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 >
/proc/sys/debug/exception-trace)

Also, all of the lines being printed are now using printk_ratelimit() to
deny the ability of DoS from a local user with a program like the
following:

main()
{
       while (1)
               if (!fork()) *(int *)0 = 0;
}

This new revision also includes the fix that Andrew did which got rid of
new sysctl that was added to the system in earlier versions of this.
Also, 'show-unhandled-signals' sysctl has been renamed back to the old
'exception-trace' to avoid breakage of people's scripts.

AK: Enabling by default for i386 will be likely controversal, but let's see what happens

[PATCH] get rid of AVC_PATH postponed treatment

        Selinux folks had been complaining about the lack of AVC_PATH
records when audit is disabled.  I must admit my stupidity - I assumed
that avc_audit() really couldn't use audit_log_d_path() because of
deadlocks (== could be called with dcache_lock or vfsmount_lock held).
Shouldn't have made that assumption - it never gets called that way.
It _is_ called under spinlocks, but not those.

        Since audit_log_d_path() uses ab->gfp_mask for allocations,
kmalloc() in there is not a problem.  IOW, the simple fix is sufficient:
let's rip AUDIT_AVC_PATH out and simply generate pathname as part of main
record.  It's trivial to do.

The sanity check in audit_match_class() is wrong.  We are able to audit
2048 syscalls but in audit_match_class() we were accidentally using
sizeof(_u32) instead of number of bits in _u32 when deciding how many
syscalls were valid.  On ia64 in particular we were hitting syscall

[POWERPC] MPIC protected sources

Some HW platforms, such as the new cell blades, requires some MPIC sources
to be left alone by the operating system. This implements support for
a "protected-sources" property in the mpic controller node containing a list

For those interested in the gory details, the MPIC on the southbridge of
those blades has some of the processor outputs routed to the cell, and
at least one routed as a GPIO to the service processor. It will be used
in the GA product for routing some of the southbridge error interrupts
to the service processor which implements some of the RAS stuff, such
as checkstopping when fatal errors occurs before they can propagate.

Paul Mackerras [Thu, 19 Jul 2007 00:00:20 +0000]
[POWERPC] Allow exec faults on readable areas on classic 32-bit PowerPC

Classic 32-bit PowerPC CPUs, and the early 64-bit PowerPC CPUs, don't
provide a way to prevent execution from readable pages, that is, the
MMU doesn't distinguish between data reads and instruction reads,
although a different exception is taken for faults in data accesses
and instruction accesses.

Commit 9ba4ace39fdfe22268daca9f28c5df384ae462cf, in the course of
fixing another bug, added a check that meant that a page fault due
to an instruction access would fail if the vma did not have the
VM_EXEC flag set.  This gives an inconsistent enforcement on these
CPUs of the no-execute status of the vma (since reading from the page
is sufficient to allow subsequent execution from it), and causes old
versions of ppc32 glibc (2.2 and earlier) to fail, since they rely
on executing the word before the GOT but don't have it marked
executable.

This fixes the problem by allowing execution from readable (or writable)
areas on CPUs which do not provide separate control over data and
instruction reads.
