* [PATCH] tty: Fix two reported pid leaksEric W. Biederman2007-03-18
| | | | | | | | | | | | | | | | | | | | | | These leaks were reported by: Catalin Marinas <catalin.marians@gmail.com> and I have been able to very by inspection they are possible. When converting tty_io.c to store pids as struct pid pointers instead of pid_t values it appears I overlooked two places where we stop using the pid value. The very obvious one is in do_tty_hangup, and the one the less obvious one in __proc_set_tty. When looking into the code __proc_set_tty only has pids that need to be put because of failures of other parts of the code to properly perform hangup processing. Fixing the leak here in __proc_set_tty is easy and obviously correct so I am doing that first. Fixing the places that should be performing hangup processing is much less obviously correct. So those I'm aiming those patches at -mm. for now, so the can age a while before they are merged. Signed-off-by: Eric W.

* [PATCH] i386: trust the PM-Timer calibration of the local APIC timerThomas Gleixner2007-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | When PM-Timer is available for local APIC timer calibration we can skip the verification of the calibrated time value. The resulting error is quite small on a bunch of evaluated platforms and is less harming than the observed false positives. We need to keep the verification on systems, which have no PM-Timer to avoid bogus local APIC timer calibrations in the range of factor 2-10, which can be observed when swicthing off the PM-timer support in the kernel configuration. The wrong calibration values are probably caused by SMM code trying to emulate a PS/2 keyboard from a (maybe connected or not) USB keyboard. This prohibits the accurate delivery of PIT interrupts, which are used to calibrate the local APIC timer. Unfortunately we have no way to disable this BIOS misfeature in the early boot process. Add also the dropped cpu_relax() back to the wait loops.

| | | | | | | | | | | | | | | | | | | | | | | | | | PAGE_MASK is an unsigned long, so using it to mask physical addresses on i386 (which are 64-bit wide) leads to truncation. This can result in page->private of unrelated memory pages being modified, with disasterous results. Fix by not using PAGE_MASK for physical addresses; instead calculate the correct value directly from PAGE_SIZE. Also fix a similar BUG_ON().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | KVM shadow page tables are always in pae mode, regardless of the guest setting. This means that a guest pde (mapping 4MB of memory) is mapped to two shadow pdes (mapping 2MB each). When the guest writes to a pte or pde, we intercept the write and emulate it. We also remove any shadowed mappings corresponding to the write. Since the mmu did not account for the doubling in the number of pdes, it removed the wrong entry, resulting in a mismatch between shadow page tables and guest page tables, followed shortly by guest memory corruption. This patch fixes the problem by detecting the special case of writing to a non-pae pde and adjusting the address and number of shadow pdes zapped accordingly.

(additionally "n" cases have been obsoleted for few years). Therefore use DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer needed CONFIG_IDEDMA_AUTO). This fixes DMA support for rare configurations where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used to enable DMA support and which were forced to PIO mode by "ide: don't allow DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch. There is no functionality loss because "ide=nodma" kernel option is still available.

However the code responsible for manually enabling DMA ("hdparm -d 1") has a bug which results in DMA being erroneously enabled - ide_set_dma() incorrectly passes "0" return value to set_using_dma(). This may work if BIOS/firmware configured the host/device for DMA and chipset allows independent configuration of DMA/PIO modes but won't work after suspend and is generally unsafe on many chipsets (possibly including data corruption if the same registers are used for DMA/PIO timings). This patch fixes kernel bugzilla bug #8169 (piix host driver fixes for setting PIO mode exposed the problem described above). The side-effect of the fix is that some rare configuration may be forced to PIO mode when DMA mode was previously used - this is addressed by the next patch which removes CONFIG_IDEDMA_{PCI,ICS}_AUTO config option completely. Thanks goes out to Patrick Horn for reporting the issue, narrowing it down to the specific commit and testing the fix. Also thanks to Sergei Shtylyov for help in debugging the problem.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver wrongly takes the address setup time into account when calculating the PIO recovery time -- this leads to slight overclocking of the PIO modes 0 and 1 (so, the prayers failed to help, as usual :-). Rework the code to be calculating recovery clock count as a difference between the total cycle count and the active count (we don't need to calculate the recovery time itself since it's not specified for the PIO modes 0 to 2, and for modes 3 and 4 this formula gives enough recovery time anyway in the chip's supported PCI frequency range). This patch has been inspired by reading the datasheets and looking at what the libata driver does; it has been compile-tested only (as usual :-) but anyway, the new code gives the same or longer recovery times than the old one...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VMI ROMs are pretty intimate to the kernel, so enforce their GPLness.

* | | [PATCH] clockevents: Fix suspend/resume to disk hangsThomas Gleixner2007-03-16

Sigh, I never figured out from the code and the bug reports what's going on. The observed hangs are caused by a stale state transition of the clock event devices, which keeps the RCU synchronization away from completion, when the non boot CPU is brought back up. The suspend/resume in oneshot mode needs the similar care as the periodic mode during suspend to RAM. My assumption that the state transitions during the different shutdown/bringups of s2disk would go through the periodic boot phase and then switch over to highres resp. nohz mode were simply wrong. Add the appropriate suspend / resume handling for the non periodic modes. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
