From 4c7f8900f1d8a0e464e7092f132a7e93f7c20f2f Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 23 Feb 2008 07:06:55 +0100 Subject: x86: stackprotector & PARAVIRT fix on paravirt enabled 64-bit kernels the paravirt ops do function calls themselves - which is bad with the stackprotector - for example pda_init() loads 0 into %gs and then does MSR_GS_BASE write (which modifies gs.base) - but that MSR write is a function call on paravirt, which with stackprotector tries to read the stack canary from the PDA ... crashing the bootup. the solution was suggested by Arjan van de Ven: to exclude paravirt.c from stackprotector, too many lowlevel functionality is in it. It's not like we'll have paravirt functions with character arrays on their stack anyway...

That does not work well with the canary-switching code there: while we already use the %rsp of the new task, we still call __switch_to() whith the previous task's canary value in the PDA, hence the __switch_to() ssp prologue instructions will store the previous canary. Then we update the PDA and upon return from __switch_to() the canary check triggers and we panic. so update the canary after we have called __switch_to(), where we are at the same stackframe level as the last stackframe of the next (and now freshly current) task. Note: this means that we call __switch_to() [and its sub-functions] still with the old canary, but that is not a problem, both the previous and the next task has a high-quality canary. The only (mostly academic) disadvantage is that the canary of one task may leak onto the stack of another task, increasing the risk of information leaks, were an attacker able to read the stack of specific tasks (but not that of others). To solve this we'll have to reorganize the way we switch tasks, and move the PDA setting into the switch_to() assembly code. That will happen in another patch.

For one, it leaked the ioremap() of the ATMU registers. Another small bug was the high 20 bits of the PCI bus address were left as zero. It's legal for prefetchable memory regions to be above 32 bits, so the high 20 bits might not be zero. Mainly, it couldn't handle ranges that were not a power of two in size or were not naturally aligned. The ATMU windows have these requirements (size & alignment), but the code didn't bother to check if the ranges it was programming met them. If they didn't, the windows would silently be programmed incorrectly. This new code can handle ranges which are not power of two sized nor naturally aligned. It simply splits the ranges into multiple valid ATMU windows. As there are only four windows, pooly aligned or sized ranges (which didn't even work before) may run out of windows. In this case an error is printed and an effort is made to disable the unmapped resources. An improvement that could be made would be to make use of the default outbound window. Iff hose->pci_mem_offset is zero, then it's possible that some or all of the ranges might not need an outbound window and could just use the default window. The default ATMU window can support a pci_mem_offset less than zero too, but pci_mem_offset is unsigned. One could say the abilities allowed a powerpc pci_controller is neither subset nor a superset of the abilities of a Freescale PCIe controller. Thankfully, the most useful bits are in the intersection of the two abilities.

These are PCI bus addresses, not CPU physical addresses. So really you're only allowed one memory range of each type. And if you want the range at a PCI address above 32 bits you must make it prefetchable.

As such, it is safe to use an unlocked test for the flag within switch_to().

This appears to be due to the initial loading of the TOC value by the secondary processor which now happens before we clear HID4:RM_CI (Real Mode Cache Invalidate). This bit should really be cleared before we do any load or store other than fetching code. This fix works based on the assumption that all SMP 64-bit PowerMacs use variants of the 970, which fortunately is true, by explicitely clearing that bit, adding an slbia for good measure as RM_CI mode is known to create bogus ERAT entries. I also removed some spurrious debug output that was left enabled by mistake while at it.

Though in upstream kernels we use new naming convention -- for IMMR address space dts files specify /immr@e0000000 nodes. This makes FSL U-Boots fail to fixup the clock frequencies, and that leads to serial ports misbehaviour. We can workaround the issue by filling the clock frequency values manually. p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for ethernet nodes, so users should either change the .dts file locally or set MAC address via `ifconfig hw ether' command.

If we enable the writing to CCR registers for 2430/34xx and don't set the default values (setting 0 as a consequence) in ASoC driver, the Transmit/Receive DMA mode gets disabled and the the transmission/reception doesn't happen, ending with a "write error: Input/Output error" when playing with 'aplay'. Also define dummy CCR registers for omap1.

But on nautilus bus->self points to the host bridge device, which is necessary as we do a root bus sizing on this system. As a result, pci_common_swizzle() loops infinitely. This worked until 2.6.29-rc1 because the alpha-specific swizzle routine checked for bus->parent == NULL (instead of bus->self). Fixed by clearing bus->self after bus sizing is done.

Unfortunately, for unknown reason these calls work only on CPU #0. So current implementation for arbitrary CPU makes CMOS_READ/WRITE to be executed on CPU #0 via IPI. However, for obvious reason this doesn't work with standard get/set_rtc_time() functions, where a bunch of CMOS accesses is done with disabled interrupts. Solved by making the IPI calls for entire get/set_rtc_time() functions, not for individual CMOS accesses. Which is also a lot more effective performance-wise. The patch is largely based on the code from Jay Estabrook. My changes: - tweak asm-generic/rtc.h by adding a couple of #defines to avoid a massive code duplication in arch/alpha/include/asm/rtc.h; - sys_marvel.c: fix get/set_rtc_time() return values (Jay's FIXMEs). NOTE: this fixes *only* LIB_RTC drivers. Legacy (CONFIG_RTC) driver wont't work on marvel. Actually I think that we should just disable CONFIG_RTC on alpha (maybe in 2.6.30?), like most other arches - AFAIK, all modern distributions use LIB_RTC anyway.

We currently only look for "ibm,slb-size" because this is what firmware actually presents. This patch makes us look for the "slb-size" property as well and in preference to the "ibm,slb-size". This should future proof us if firmware changes to match PAPR.

The script was originally written by Arnd Bergman and exten by me to cover a few more files. When the header files differed the script uses the following: The original m68k file is named _mm.h [mm for memory manager] The m68knommu file is named _no.h [no for no memory manager] The files uses the following include guard: This include gaurd works as the m68knommu toolchain set the __uClinux__ symbol - so this should work in userspace too. Merging the header files for m68k and m68knommu exposes the (unexpected?) ABI differences thus it is easier to actually identify these and thus to fix them. The commit has been build tested with both a m68k and a m68knommu toolchain - with success. The commit has also been tested with "make headers_check" and this patch fixes make headers_check for m68knommu.

Beulich Date: Fri, 16 Jan 2009 11:59:33 +0000 Subject: x86: fix assumed to be contiguous leaf page tables for kmap_atomic region (take 2) Debugging and original patch from Nick Piggin The early fixmap pmd entry inserted at the very top of the KVA is causing the subsequent fixmap mapping code to not provide physically linear pte pages over the kmap atomic portion of the fixmap (which relies on said property to calculate pte addresses). This has caused weird boot failures in kmap_atomic much later in the boot process (initial userspace faults) on a 32-bit PAE system with a larger number of CPUs (smaller CPU counts tend not to run over into the next page so don't show up the problem). Solve this by attempting to clear out the page table, and copy any of its entries to the new one. Also, add a bug if a nonlinear condition is encountered and can't be resolved, which might save some hours of debugging if this fragile scheme ever breaks again... Once we have such logic, we can also use it to eliminate the early ioremap trickery around the page table setup for the fixmap area. This also fixes potential issues with FIX_* entries sharing the leaf page table with the early ioremap ones getting discarded by early_ioremap_clear() and not restored by early_ioremap_reset(). It at once eliminates the temporary (and configuration, namely NR_CPUS, dependent) unavailability of early fixed mappings during the time the fixmap area page tables get constructed. Finally, also replace the hard coded calculation of the initial table space needed for the fixmap area with a proper one, allowing kernels configured for large CPU counts to actually boot.

A new PHDR is added as existing ones cannot contain sections near address zero. PERCPU_VADDR() also adds a new symbol __per_cpu_load which always points to the vaddr of the loaded percpu data.init region. The following adjustments have been made to accomodate the address change. * code to locate percpu gdt_page in head_64.S is updated to add the load address to the gdt_page offset. * __per_cpu_load is used in places where access to the init data area is necessary. * pda->data_offset is initialized soon after C code is entered as zero value doesn't work anymore. This patch is mostly taken from Mike Travis' "x86_64: Base percpu variables at zero" patch.

This patch folds pda into percpu area. Due to strange gcc requirement, pda needs to be at the beginning of the percpu area so that pda->stack_canary is at %gs:40. To achieve this, a new percpu output section macro - PERCPU_VADDR_PREALLOC() - is added and used to reserve pda sized chunk at the start of the percpu area. After this change, for boot cpu, %gs first points to pda in the data.init area and later during setup_per_cpu_areas() gets updated to point to the actual pda. This means that setup_per_cpu_areas() need to reload %gs for CPU0 while clearing pda area for other cpus as cpu0 already has modified it when control reaches setup_per_cpu_areas(). This patch also removes now unnecessary get_local_pda() and its call sites. A lot of this patch is taken from Mike Travis' "x86_64: Fold pda into per cpu area" patch.

Unify x86_64 SMP percpu access with x86_32 SMP one. Other than the segment register, operand size and the base of percpu symbols, they behave identical now. This patch replaces now unnecessary pda->data_offset with a dummy field which is necessary to keep stack_canary at its place. This patch also moves per_cpu_offset initialization out of init_gdt() into setup_per_cpu_areas(). Note that this change also necessitates explicit per_cpu_offset initializations in voyager_smp.c. With this change, x86_OP_percpu()'s are as efficient on x86_64 as on x86_32 and also x86_64 can use assembly PER_CPU macros.

Make it so by defining per cpu symbol from linker script and declaring it in C code for SMP and simply defining it for UP. This change cleans up code and brings SMP and UP closer a bit.

(other architectures will fall back to a default implementation) The advantage is that for example to read a local percpu variable, instead of this sequence: return __get_cpu_var(var); ffffffff8102ca2b: 48 8b 14 fd 80 09 74 mov -0x7e8bf680(,%rdi,8),%rdx ffffffff8102ca32: 81 ffffffff8102ca33: 48 c7 c0 d8 59 00 00 mov $0x59d8,%rax ffffffff8102ca3a: 48 8b 04 10 mov (%rax,%rdx,1),%rax We can get a single instruction by using the optimized variants: return percpu_read(var); ffffffff8102ca3f: 65 48 8b 05 91 8f fd mov %gs:0x7efd8f91(%rip),%rax I also cleaned up the x86-specific APIs and made the x86 code use these new generic percpu primitives. tj: * fixed generic percpu_sub() definition as Roel Kluin pointed out * added percpu_and() for completeness's sake * made generic percpu ops atomic against preemption Signed-off-by: Ingo Molnar Signed-off-by: Tejun Heo --- arch/x86/include/asm/current.h | 2 +- arch/x86/include/asm/irq_regs_32.h | 4 ++-- arch/x86/include/asm/mmu_context_32.h | 12 ++++++------ arch/x86/include/asm/pda.h | 10 +++++----- arch/x86/include/asm/percpu.h | 24 +++++++++++++----------- arch/x86/include/asm/smp.h | 2 +- arch/x86/kernel/process_32.c | 2 +- arch/x86/kernel/tlb_32.c | 10 +++++----- arch/x86/mach-voyager/voyager_smp.c | 4 ++-- arch/x86/xen/enlighten.c | 14 +++++++------- arch/x86/xen/irq.c | 8 ++++---- arch/x86/xen/mmu.c | 2 +- arch/x86/xen/multicalls.h | 2 +- arch/x86/xen/smp.c | 2 +- 14 files changed, 50 insertions(+), 48 deletions(-) (limited to 'arch') diff --git a/arch/x86/include/asm/current.h b/arch/x86/include/asm/current.h index 0930b4f8d672..0728480f5c56 100644 --- a/arch/x86/include/asm/current.h +++ b/arch/x86/include/asm/current.h @@ -10,7 +10,7 @@ struct task_struct;

But this resulted in modpost failures if there where no in-kernel users because then insw & friends were not linked in. Fix this by including PeeCeeI.o in the kernel unconditionally. The only drawback for this solution is that a nonmodular kernel will always include insw & friends no matter if they are in use or not.

Apparently, clk_get in pxamci will also fail for MCI2 on PXA310. The 'clk_find' and therefore 'clk_get' require driver to supply both 'dev_id' and 'con_id' if they are not NULL in the 'strcut clk_lookup', but neither pxa3xx_nand nor pxamci supply 'con_id'. This patch sets 'con_id' to NULL in NAND clock and MCI2 clock registration.

That implementation does not call arch_setup_msi_irq(), instead it calls setup_irq(). No other x86 code calls arch_setup_msi_irq(). That leaves only arch_setup_msi_irqs() in drivers/pci/msi.c, but that routine is overridden by the x86 version of arch_setup_msi_irqs(). So arch_setup_msi_irq() is dead code, remove it.

CM contains, among other blocks, an Interrupt Generator (IG) and a Clock and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are supported over dmaengine and irq-chip APIs respectively. IDMAC is a specialised DMA controller, its DMA channels cannot be used for general-purpose operations, even though it might be possible to configure a memory-to-memory channel for memcpy operation. This driver will not work with generic dmaengine clients, clients, wishing to use it must use respective wrapper structures, they also must specify which channels they require, as channels are hard-wired to specific IPU functions.

This patch eliminates the crash caused by the int3 trap by moving the non-inlined kernel_physical_mapping_init() from .init.text to .meminit.text.

I consider this actually to be somewhat of a cleanup too: the main function now contains about half the number of lines so the normal path is easier to read, while the error cases are also nicely split away. Also, ensure the order of arguments to functions is always the same: regs, addr, error_code. This can reduce code size a tiny bit, and just looks neater too. And add a couple of branch annotations. Before: do_page_fault: subq $360, %rsp #, After: do_page_fault: subq $56, %rsp #, bloat-o-meter: add/remove: 8/0 grow/shrink: 0/1 up/down: 2222/-1680 (542) function old new delta __bad_area_nosemaphore - 506 +506 no_context - 474 +474 vmalloc_fault - 424 +424 spurious_fault - 358 +358 mm_fault_error - 272 +272 bad_area_access_error - 89 +89 bad_area - 89 +89 bad_area_nosemaphore - 10 +10 do_page_fault 2464 784 -1680 Yes, the total size increases by 542 bytes, due to the extra function calls. But these will very rarely be called (except for vmalloc_fault) in a normal workload. Importantly, do_page_fault is less than 1/3rd it's original size, and touches far less stack. Existing gotos and branch hints did move a lot of the infrequently used text out of the fastpath, but that's even further improved after this patch.
