12 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.

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...

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

although the real fix is having the X server always retry EINTR

12 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.

                                                             ^^^^^^^^
It uses RTL_GIGA_MAC_VER_05 and this part of the changeset can cut
its performance by a factor of 2~2.5 as reported by Timo.

(the driver includes code just before the hunk to write the ChipCmd

12 years agoRemove unnecessary cast in prefetch()
Serge Belyshev [Thu, 4 Oct 2007 21:10:04 +0000]
Remove unnecessary cast in prefetch()

It is ok to call prefetch() function with NULL argument, as specifically
commented in include/linux/prefetch.h.  But in standard C, it is invalid
to dereference NULL pointer (see C99 standard 6.5.3.2 paragraph 4 and
note #84).

prefetch() has a memory reference for its argument.

Newer gcc versions (4.3 and above) will use that to conclude that "x"
argument is non-null and thus wreaking havok everywhere prefetch() was
inlined.

Fixed by removing cast and changing asm constraint.

[ It seems in theory gcc 4.2 could miscompile this too; although no
  cases known.  In 2.6.24 we should probably switch to
  __builtin_prefetch() instead, but this is a simpler fix for now.

12 years agoFix sys_remap_file_pages BUG at highmem.c:15!
Hugh Dickins [Thu, 4 Oct 2007 15:56:06 +0000]
Fix sys_remap_file_pages BUG at highmem.c:15!

Gurudas Pai reports kernel BUG at arch/i386/mm/highmem.c:15! below
sys_remap_file_pages, while running Oracle database test on x86 in 6GB
RAM: kunmap thinks we're in_interrupt because the preempt count has
wrapped.

That's because __do_fault expected to unmap page_table, but one of its
two callers do_nonlinear_fault already unmapped it: let do_linear_fault
unmap it first too, and then there's no need to pass the page_table arg
down.

Why have we been so slow to notice this? Probably through forgetting
that the mapping_cap_account_dirty test means that sys_remap_file_pages
nowadays only goes the full nonlinear vma route on a few memory-backed
filesystems like ramfs, tmpfs and hugetlbfs.

[ It also depends on CONFIG_HIGHPTE, so it becomes even harder to
  trigger in practice. Many who have need of large memory have probably
  migrated to x86-64..

  Problem introduced by commit d0217ac04ca6591841e5665f518e38064f4e65bd

David S. Miller [Thu, 4 Oct 2007 04:37:57 +0000]
[SPARC64]: Temporary workaround for PCI-E slot on T1000.

The PCI-E slot on T1000 connects directly to the Fire PCI chip with no
intervening bridges visible in the OBP tree.

Unfortunately the bus numbering of the device in that slot is
different (2) from the PCI host controller (0), and thus the
pci_bus_{read,write}_config_*() calls don't work out.

Complicating things further the Fire PCI controller has no config
space it responds to either.

For now treat this case specially so that devices in the slot work.

Longer term we need to perhaps cons up a dummy bridge between the Fire
and the PCI-E slot so that the bus hierarchy is complete inside of the
kernel and thus the bus numbering all works out right.
