* file caps: always start with clear bprm->caps_*Serge Hallyn2008-11-01
| | | | | | | | | | | | | | | | While Linux doesn't honor setuid on scripts. However, it mistakenly behaves differently for file capabilities. This patch fixes that behavior by making sure that get_file_caps() begins with empty bprm->caps_*. That way when a script is loaded, its bprm->caps_* may be filled when binfmt_misc calls prepare_binprm(), but they will be cleared again when binfmt_elf calls prepare_binprm() next to read the interpreter's file capabilities.

|\ | | | | | | | | | | * 'for-2.6.28' of git://linux-nfs.org/~bfields/linux: NLM: Set address family before calling nlm_host_rebooted() nfsd: fix failure to set eof in readdir in some situations
| * NLM: Set address family before calling nlm_host_rebooted()Chuck Lever2008-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The nlm_host_rebooted() function uses nlm_cmp_addr() to find an nsm_handle that matches the rebooted peer. In order for this to work, the passed-in address must have a proper address family. This fixes a post-2.6.28 regression introduced by commit 781b61a6, which added AF_INET6 support to nlm_cmp_addr(). Before that commit, nlm_cmp_addr() didn't care about the address family; it compared only the sin_addr.s_addr field for equality. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

| * nfsd: fix failure to set eof in readdir in some situationsJ. Bruce Fields2008-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before 14f7dd632011bb89c035722edd6ea0d90ca6b078 "[PATCH] Copy XFS readdir hack into nfsd code", readdir_cd->err was reset to eof before each call to vfs_readdir; afterwards, it is set only once. Similarly, c002a6c7977320f95b5edede5ce4e0eeecf291ff "[PATCH] Optimise NFS readdir hack slightly", can cause us to exit without nfserr_eof set. Fix this. This ensures the "eof" bit is set when needed in readdir replies. (The particular case I saw was an nfsv4 readdir of an empty directory, which returned with no entries (the protocol requires "." and ".." to be filtered out), but with eof unset.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale implementation of MPIC only allows a single CPU destination for non-IPI interrupts. We add a flag to the mpic_init to distinquish these variants of MPIC. We pull in the irq_choose_cpu from sparc64 to select a single CPU as the destination of the interrupt. This is to deal with the fact that the default smp affinity was changed by commit 18404756765c713a0be4eb1082920c04822ce588 ("genirq: Expose default irq affinity mask (take 3)") to be all CPUs.

| * | | powerpc: Update remaining dma_mapping_ops to use map/unmap_pageMark Nelson2008-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the merge of the 32 and 64bit DMA code, dma_direct_ops lost their map/unmap_single() functions but gained map/unmap_page(). This caused a problem for Cell because Cell's dma_iommu_fixed_ops called the dma_direct_ops if the fixed linear mapping was to be used or the iommu ops if the dynamic window was to be used. So in order to fix this problem we need to update the 64bit DMA code to use map/unmap_page. First, we update the generic IOMMU code so that iommu_map_single() becomes iommu_map_page() and iommu_unmap_single() becomes iommu_unmap_page(). Then we propagate these changes up through all the callers of these two functions and in the process update all the dma_mapping_ops so that they have map/unmap_page rahter than map/unmap_single. We can do this because on 64bit there is no HIGHMEM memory so map/unmap_page ends up performing exactly the same function as map/unmap_single, just taking different arguments. This has no affect on drivers because the dma_map_single_attrs() just ends up calling the map_page() function of the appropriate dma_mapping_ops and similarly the dma_unmap_single_attrs() calls unmap_page(). This fixes an oops on Cell blades, which oops on boot without this because they call dma_direct_ops.map_single, which is NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A typo/thinko made us pass the wrong argument to __flush_hash_table_range when unplugging bridges, thus not flushing all the translations for the IO space on unplug. The third parameter to __flush_hash_table_range is `end', not `size'. This causes the hypervisor to refuse unplugging slots.

Not having these resources allocated causes an oops when removing the PHB when we try to release them. The diff appears a bit messy, this is mainly due to moving everything one tab to the left in the pcibios_allocate_bus_resources routine. The functionality change in this routine is only that the list_for_each_entry() loop is pulled out and moved to the necessary calling routine.

A program using the sys_swapcontext system call and supplying smaller ucontext_t structures will currently get an EINVAL error if the task has used VSX (e.g. because of calling library code that uses VSX) and the old_ctx argument is non-NULL (i.e. the program is asking for its current context to be saved). Thus the program will start getting EINVAL errors on calls that previously worked. This commit changes this behaviour so that we don't send an EINVAL in this case. It will now return the smaller context but the VSX MSR bit will always be cleared to indicate that the ucontext_t doesn't include the extra VSX state, even if the task has executed VSX instructions. Both 32 and 64 bit cases are updated. [paulus@samba.org - also fix some access_ok() and get_user() calls] Thanks to Ben Herrenschmidt for noticing this problem.

However, those lines seem to trigger a bug in older versions of GNU ld (such as 2.16.1) when building a non-relocatable kernel. Since ld 2.16.1 is still a popular choice for cross-toolchains, this adds an #ifdef to vmlinux.lds.S so the added lines are only included when building a relocatable kernel.

As of 2.6.27, the kernel entry point has 4 constraints: Offset 0 is the starting point for the master (boot) cpu (entered with r3 pointing to the device tree structure), offset 0x60 is code for the slave cpus (entered with r3 set to their device tree physical id), offset 0x20 is used by the iseries hypervisor, and secondary cpus must be well behaved when the first 256 bytes are copied to address 0. Placing the __kdump_flag at 0x18 is bad because: - It was taking the last 8 bytes before the iseries hypervisor data. - It was 8 bytes for a boolean flag - It had no way of identifying that the flag was present - It does leave any room for the master to add any additional code before branching, which hurts debug. - It will be unnecessarily hard for 32 bit code to be common (8 bytes) Now that we have eliminated the use of __kdump_flag in favor of the standard is_kdump_kernel(), this flag only controls run without relocating the kernel to PHYSICAL_START (0), so rename it __run_at_load. Move the flag to 0x5c, 1 word before the secondary cpu entry point at 0x60. Initialize it with "run0" to say it will run at 0 unless it is set to 1. It only exists if we are relocatable.

This part is wrong and is reverted by this commit. The kernel gets a list of memory blocks and a entry point from user space. Its job is to copy the blocks into place and then branch to the designated entry point (after turning "off" the mmu). The user space tool inserts a trampoline, called purgatory, that runs before the user supplied code. Its job is to establish the entry environment for the new kernel or other application based on the contents of memory. The purgatory code is compiled and embedded in the tool, where it is later patched using the elf symbol table using elf symbols. Since the tool knows it is creating a purgatory that will run after a kernel crash, it should just patch purgatory (or the kernel directly) if something needs to happen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the recent commit to kill off SCI/SCIF special casing SH 7751R fails to compile with CONFIG_SH_RTS7751R2D set. This is because SCSPTR1 is undefined. Take the value for SCSPTR1 from the SH7751R Group Hardware Manual. Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | SH-5 doesn't support any elaborate ISA inheritance schemes (-dsp, -up, etc.), so only bother with that if we are building an sh32 kernel. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: Kill off long-dead HD64465 cchip support.Paul Mundt2008-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code has been dead for many years. The last update it received was in 2003 in order to update it for the driver model changes, though it had already been in disarray and unused before that point. The only boards that ever used this chip have not had users in many years either, so it is finally safe to just kill it off and move on with life. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than varying this on a subtype level, we use the counter type as a generic identifier.

The DSP and FPU generation are already at odds with each other, and the nommu tuning we weren't handling at all. Additionally, for platforms that never had an FPU, the -nofpu variant never existed, meaning that we would lose out on family granular tuning completely in certain cases. With tat out of the way, we were also using -up versions, allowing for later instructions that branched off of a particular subset of the ISA, but are not actually reflected on the hardware being targetted. This leads to some confusion, and the possibility of bogus instructions on older parts. Kill that off and lock it down to the family being built for specifically.
