Print out debug info, as early as possible - even before the
kernel initializes the interrupt vectors. Now we can print out debug
messages almost anytime during the boot process.

Also ensure that the traps_c code doesn't cause a double fault, by

Correct Makefile rule for generating custom keymap

When building a custom keymap, after setting GENERATE_KEYMAP := 1 in
drivers/char/Makefile, the kernel build fails like this:

CC drivers/char/vt.o

  make[1]: *** [drivers/char] Error 2

This was caused by commit af8b128719f5248e542036ea994610a29d0642a6, which
deleted a necessary colon from the Makefile rule that generates the keymap,
since that rule contains both a target and a target-pattern.  The following

13 years ago[IPv6]: Fix ICMPv6 redirect handling with target multicast address
Brian Haley [Mon, 8 Oct 2007 07:12:05 +0000]
[IPv6]: Fix ICMPv6 redirect handling with target multicast address

When the ICMPv6 Target address is multicast, Linux processes the
redirect instead of dropping it.  The problem is in this code in
ndisc_redirect_rcv():

         if (ipv6_addr_equal(dest, target)) {
                 on_link = 1;
         } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) {
                 ND_PRINTK2(KERN_WARNING
                            "ICMPv6 Redirect: target address is not
link-local.\n");
                 return;
         }

This second check will succeed if the Target address is, for example,
FF02::1 because it has link-local scope.  Instead, it should be checking
if it's a unicast link-local address, as stated in RFC 2461/4861 Section
8.1:

       - The ICMP Target Address is either a link-local address (when
         redirected to a router) or the same as the ICMP Destination
         Address (when redirected to the on-link destination).

I know this doesn't explicitly say unicast link-local address, but it's
implied.

This bug is preventing Linux kernels from achieving IPv6 Logo Phase II
certification because of a recent error that was found in the TAHI test
suite - Neighbor Disovery suite test 206 (v6LC.2.3.6_G) had the
multicast address in the Destination field instead of Target field, so
we were passing the test.  This won't be the case anymore.

The patch below fixes this problem, and also fixes ndisc_send_redirect()
to not send an invalid redirect with a multicast address in the Target
field.  I re-ran the TAHI Neighbor Discovery section to make sure Linux
passes all 245 tests now.

Ilpo Järvinen [Mon, 8 Oct 2007 06:43:10 +0000]
[TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKed

When only GSO skb was partially ACKed, no hints are reset,
therefore fastpath_cnt_hint must be tweaked too or else it can
corrupt fackets_out. The corruption to occur, one must have
non-trivial ACK/SACK sequence, so this bug is not very often
that harmful. There's a fackets_out state reset in TCP because
fackets_out is known to be inaccurate and that fixes the issue
eventually anyway.

In case there was also at least one skb that got fully ACKed,
the fastpath_skb_hint is set to NULL which causes a recount for
fastpath_cnt_hint (the old value won't be accessed anymore),
thus it can safely be decremented without additional checking.

13 years agofix bogus reporting of signals by audit
Al Viro [Sun, 7 Oct 2007 07:24:36 +0000]
fix bogus reporting of signals by audit

Async signals should not be reported as sent by current in audit log.  As
it is, we call audit_signal_info() too early in check_kill_permission().
Note that check_kill_permission() has that test already - it needs to know
if it should apply current-based permission checks.  So the solution is to
move the call of audit_signal_info() between those.

Bogosity in question is easily reproduced - add a rule watching for e.g.
kill(2) from specific process (so that audit_signal_info() would not
short-circuit to nothing), say load_policy, watch the bogus OBJ_PID entry
in audit logs claiming that write(2) on selinuxfs file issued by
load_policy(8) had somehow managed to send a signal to syslogd...

Longhaul: add auto enabled "revid_errata" option

VIA C3 Ezra-T has RevisionID equal to 1, but it needs RevisionKey to be 0
or CPU will ignore new frequency and will continue to work at old
frequency.  New "revid_errata" option will force RevisionKey to be set to
0, whatever RevisionID is.

Additionaly "Longhaul" will not silently ignore unsuccessful transition.
It will try to check if "revid_errata" or "disable_acpi_c3" options need to
be enabled for this processor/system.

Same for Longhaul ver.  2 support.  It will be disabled if none of above
options will work.

 Best case scenario (with patch apllied and v2 enabled):
 longhaul: VIA C3 'Ezra' [C5C] CPU detected.  Longhaul v2 supported.
 longhaul: Using northbridge support.
 longhaul: VRM 8.5
 longhaul: Max VID=1.350  Min VID=1.050, 13 possible voltage scales
 longhaul: f: 300000 kHz, index: 0, vid: 1050 mV
 [...]
 longhaul: Voltage scaling enabled.
 Worst case scenario:
 longhaul: VIA C3 'Ezra-T' [C5M] CPU detected.  Powersaver supported.
 longhaul: Using northbridge support.
 longhaul: Using ACPI support.
 longhaul: VRM 8.5
 longhaul: Claims to support voltage scaling but min & max are both 1.250. Voltage scaling disabled
 longhaul: Failed to set requested frequency!
 longhaul: Enabling "Ignore Revision ID" option.
 longhaul: Failed to set requested frequency!

Fix timer_stats printout of events/sec

When using /proc/timer_stats on ppc64 I noticed the events/sec field wasnt
accurate.  Sometimes the integer part was incorrect due to rounding (we
werent taking the fractional seconds into consideration).

The fraction part is also wrong, we need to pad the printf statement and
take the bottom three digits of 1000 times the value.

13 years agoDon't do load-average calculations at even 5-second intervals
Linus Torvalds [Sun, 7 Oct 2007 23:17:38 +0000]
Don't do load-average calculations at even 5-second intervals

It turns out that there are a few other five-second timers in the
kernel, and if the timers get in sync, the load-average can get
artificially inflated by events that just happen to coincide.

So just offset the load average calculation it by a timer tick.

Noticed by Anders Boström, for whom the coincidence started triggering
on one of his machines with the JBD jiffies rounding code (JBD is one of
the subsystems that also end up using a 5-second timer by default).

13 years agoVT_WAITACTIVE: Avoid returning EINTR when not necessary
Linus Torvalds [Sun, 7 Oct 2007 23:02:55 +0000]
VT_WAITACTIVE: Avoid returning EINTR when not necessary

We should generally prefer to return ERESTARTNOHAND rather than EINTR,
so that processes with unhandled signals that get ignored don't return
EINTR.

This can help with X startup issues:

    Fatal server error:
    xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call

although the real fix is having the X server always retry EINTR
regardless (since EINTR does happen for signals that have handlers
installed). Keithp has a patch for that.

Regardless, ERESTARTNOHAND is the correct thing to use.

13 years agoFix non-terminated PCI match table in PowerMac IDE

Fix non-terminated PCI match table in PowerMac IDE

The PCI device table in the powermac IDE driver isn't properly
terminated.  Depending on how your kernel is linked and other random
factors, you can end up with this driver matched against any other PCI
device in your system, possibly crashing at boot.

Thanks to Heikki for tracking this down with me, the bug have been there
for some time, though it rarely hurts due to luck.  In this case, the
switch from .22 to .23-rc9 is causing it to show up due to differences
in the resulting layout of .data I suppose.

13 years agoxen: disable split pte locks for now
Jeremy Fitzhardinge [Sat, 6 Oct 2007 00:19:35 +0000]
xen: disable split pte locks for now

When pinning and unpinning pagetables, we must protect them against
being used by other CPUs, lest they see the pagetable in an
intermediate read-only-but-not-pinned state.

When using split pte locks, doing this properly would require taking
all the pte locks for the pagetable while pinning, but this may overflow
the PREEMPT_BITS part of the preempt counter if the process has mapped
more than about 512M of memory.

However, failing to take the pte locks causes write-protect faults when
the pageout code is trying to clear the Access bit on a pte which is part
of a freshy created and still being pinned process after fork.

This is a short-term fix until the problem is solved properly.
