This patch fixes a wrong ifdef in the board setup code, leading to the GPIO pin not being pulled high, and thus the USB switch not being powered at all. This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which started in 2005 (before 2.6.12-rc2), then probably because things were working anyway for most people got forgotten. [Ralf: Paolo's original patch didn't fix the module case, Florian's patch only fixed MTX1 etc. so this is a combined patch plus some cleanups.] Cc: Giuseppe Patanè <giuseppe.patane@tvblob.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: NPaolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NFelix Fietkau <nbd@openwrt.org> Signed-off-by: NJohn Crispin <blogic@openwrt.org> Signed-off-by: NFlorian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

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.

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.

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...

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.

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).

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).

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.

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.
