I recently learnt that limiting RAM with by using only "mem=xxxM" is no good on machines equipped with PCI. In my case (vanilla 2.6.9) the cardbus bridge on my laptop got mapped to the unused RAM area which resulted in wierd errors due to the collision. The right solution is to use "mem=" together with "memmap=" to mark the unused RAM area reserved. Henceforth I force the kernel to use 2016MiB by passing "mem=2016M memmap=32M#2016M" instead of just "mem=2016M". Signed-off-by:

This patch fixes a problem where /dev/urandom can return duplicate values when two processors read from it at the same time. It relies on the fact that we already are taking a lock in add_entropy_words(), and atomically hashes in some freshly mixed in data into the returned randomness. Signed-off-by:

As of 2.6.10-rc3, the following is needed to allow various userland packages (sysvinit, dhcp, ppp, libcap, libpcap, lilo) to compile as parts that userland needs (e.g. for ioctls) is in files with stuff userland isn't allowed to see. This adds __KERNEL__ around <linux/ata.h> and some defines (<linux/ata.h> isn't needed by userland, and is unhappy right now). sysvinit and some other packages need <linux/hdreg.h> for HDIO_DRIVE_CMD and other IOCTL things. In <linux/types.h> we were unsafely typedef'ing __le64/__be64 as __u64 only exists when __GNUC__ && !__STRICT_ANSI__ (causing libcap to fail, for example). Finally, <asm/atomic.h> provides routines userland simply cannot use on all arches, but <linux/filter.h> is needed by iputils for example. While not all arches put __KERNEL__ around their header, on MIPS including this header currently blows up the build. Signed-off-by:

It turns out there are more issues with our VPA code: 1. vpa_init doesnt report errors when it fails. This was masking a bug where the VPA spanned 2 pages and phyp failed to register it. 2. We call idle_setup before we initialise the boot cpus vpa. This means we never select the shared processor idle loop. 3. We dont call vpa_init on UP kernels. Signed-off-by:

ppc64 has a global called "pci_probe_only" which, when set, prevents the arch PCI code from calling pci_assign_unassigned_resources(). This was cleared by pmac so far, but a bug in the definition of the variable make that ineffective until 2.6.10, and so we never called pci_assign_unassigned_resources(). With 2.6.10, that bug was fixed and so we now call it, which results in some problems. Some devices who have perfectly valid assigned addresses by firmware end up beeing moved around anyway, which is a BAD thing can can break boot on some machines since it breaks the relationship between addresses in Open Firmware device-tree and actual location of PCI devices. (Some low level things like the PIC are ioremap'ed based on their OF address, way before the PCI based ASIC hosting them has been found). This also break the "offb" default framebuffer driver since the video card ends up beeing moved around as well. For now, the fix is to set pci_probe_only on pmac, thus reverting to the old behaviour. In the long run, it would be interesting to "fix" pci_assign_unassigned_resources() so that it does what it's name claims, and only assigns things that have been left unassigned instead of moving things around gratuituously...

Sometimes /proc/<pid>/status shows VmLib: 42949..... kB. mprotect_fixup must note oldflags on entry: if vma_merge is successful, vma->vm_flags afterwards may be either the oldflags or the newflags, and the extent of the change will be less than the extent of the vma. And let's use unsigned long for these flags throughout. Signed-off-by:

In some cases /proc/<pid>/status shows VmLib: 42949..... kB. If READ_IMPLIES_EXEC then the break area is VM_EXEC, but omitted from exec_vm since do_brk contains no __vm_stat_account call. Later munmaps count its pages out of exec_vm, hence (exec_vm - VmExe) can go negative. do_brk is right not to call __vm_stat_account, its pages shouldn't need to be counted. What's wrong is that __vm_stat_account is counting all the VM_EXEC pages, whereas (to mimic 2.4 and earlier 2.6) it should be leaving VM_WRITE areas and non-vm_file areas out of exec_vm. VmLib may still appear larger than before - where a READ_IMPLIES_EXEC personality makes what was a readonly mapping of a file now executable e.g. /usr/lib/locale stuff. And a program which mprotects its own text as writable will appear with wrapped VmLib: sorry, but while it's worth showing ordinary programs as ordinary, it's not worth much effort to avoid showing odd ones as odd.

Michael Kerrisk has observed that at present any process can SHM_LOCK any shm segment of size within process RLIMIT_MEMLOCK, despite having no permissions on the segment: surprising, though not obviously evil. And any process can SHM_UNLOCK any shm segment, despite no permissions on it: that is surely wrong. Unless CAP_IPC_LOCK, restrict both SHM_LOCK and SHM_UNLOCK to when the process euid matches the shm owner or creator: that seems the least surprising behaviour, which could be relaxed if a need appears later.

When drives go offline, e.g. usb-storage disconnect, the upper layers don't behave very intelligently yet: ext3 over scsi keeps retrying reads, logging three lines for each error: 10:58:31 scsi0 (0:0): rejecting I/O to dead device 10:58:31 EXT3-fs error (device sda1): ext3_find_entry: reading directory #18089296 offset 0 10:58:31 10:59:47 EXT3-fs error (device sda1): ext3_find_entry: reading directory #18089296 offset 0 This patch shrinks that log spam by the trivial third, getting rid of those needless blank lines. It's not clear to me why the "no such device" errors don't immediately make ext3 (or is it the block layer?) give up ... maybe someone else can make Linux not retry after those errors. Signed-off-by:

Recently I tried booting a UP kernel on a 1-processor logical partition on a POWER4 system. It failed because the CPU we happened to be running on was CPU 2, but hard_smp_processor_id() is defined to 0 for !CONFIG_SMP. (Note that this code runs quite early, as part of init_IRQ, so hard_smp_processor_id() should be the physical ID of the boot cpu.) This patch does a minimal fix to make it work. I think this patch should go in 2.6.10. Ultimately I think the hard_smp_processor_id() definition should be removed from include/linux/smp.h, but that carries a risk of breaking other architectures and probably shouldn't be done pre 2.6.10.

Found a subtle bug that caused mount errors on a SATA drive with barriers on reiser and ext3, where it should have recovered and just turned off barriers. The problem is that the EOPNOTSUPP error isn't being propagated properly to the bounced bio. This patch fixes that by correctly passing error all the way down. Signed-off-by:

This patch is from Will Schmidt <willschm@us.ibm.com>, with some extra comments from me. On iSeries and on POWER5 machines, there is a data structure which is used for communication between the hypervisor and the kernel, called the `lppaca'. The kernel tells the hypervisor where it is, and the hypervisor requires that it doesn't cross a page boundary. With other changes in the last few months we have ended up with a situation where it could cross a page boundary. This patch increases the alignment requirement for the struct to make sure that it can't cross a page boundary. This is a bug fix and should go into 2.6.10. Signed-off-by:
