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. 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.

When using /proc/timer_stats on ppc64 I noticed the events/sec field wasnt accurate.

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).

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. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

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.

由 Jeremy Fitzhardinge 提交于
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 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. -- AK ] Signed-off-by: NSerge Belyshev <belyshev@depni.sinp.msu.ru> Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

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..

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.
