由 Roland McGrath 提交于
This fixes an arcane bug that we think was a regression introduced by commit b2b2cbc4. When a parent ignores SIGCHLD (or uses SA_NOCLDWAIT), its children would self-reap but they don't if it's using ptrace on them. When the parent thread later exits and ceases to ptrace a child but leaves other live threads in the parent's thread group, any zombie children are left dangling. The fix makes them self-reap then, as they would have done earlier if ptrace had not been in use. Signed-off-by: NRoland McGrath <roland@redhat.com>

This reverts the effect of commit f2cc3eb1 "do_wait: fix security checks". That change reverted the effect of commit 73243284. The rationale for the original commit still stands. The inconsistent treatment of children hidden by ptrace was an unintended omission in the original change and in no way invalidates its purpose. This makes do_wait return the error returned by security_task_wait() (usually -EACCES) in place of -ECHILD when there are some children the caller would be able to wait for if not for the permission failure. A permission error will give the user a clue to look for security policy problems, rather than for mysterious wait bugs. Signed-off-by: NRoland McGrath <roland@redhat.com>

由 Roland McGrath 提交于
ptrace no longer fiddles with the children/sibling links, and the old ptrace_children list is gone. Now ptrace, whether of one's own children or another's via PTRACE_ATTACH, just uses the new ptraced list instead. There should be no user-visible difference that matters. The only change is the order in which do_wait() sees multiple stopped children and stopped ptrace attachees. Since wait_task_stopped() was changed earlier so it no longer reorders the children list, we already know this won't cause any new problems. Signed-off-by: NRoland McGrath <roland@redhat.com>

The (1.0 inherited) separate length fields in the FADT are byte granular. Further, PM1a/b may have distinct lengths and live in distinct address spaces. acpi_tb_convert_fadt() should account for all of these conditions. Apart from these changes I'm puzzled by the fact that, not just for acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an explicit size passed rather than using the size found in the passed GAS. What happens on a platform that defines PM1{a,b} wider than 16 bits? Of course, acpi_hw_low_level_{read,write}() at present are entirely un-prepared to deal with sizes other than 8, 16, or 32, not to speak of a non-zero bit_offset or access_width...

The HP CCSR descriptor describes MMIO address space that should appear as a MEM resource. This patch adds support for parsing these descriptors in the _CRS data. The visible effect of this is that these MEM resources will appear in /sys/devices/pnp0/.../resources, which means that "lspnp -v" will report it, user applications can use this to locate device CSR space, and kernel drivers can use the normal PNP resource accessors to locate them.

由 Bjorn Helgaas 提交于
ISAPNP, PNPBIOS, and ACPI describe the "possible resource settings" of a device, i.e., the possibilities an OS bus driver has when it assigns I/O port, MMIO, and other resources to the device. PNP used to maintain this "possible resource setting" information in one independent option structure and a list of dependent option structures for each device. Each of these option structures had lists of I/O, memory, IRQ, and DMA resources, for example: dev independent options ind-io0 -> ind-io1 ... ind-mem0 -> ind-mem1 ... ... dependent option set 0 dep0-io0 -> dep0-io1 ... dep0-mem0 -> dep0-mem1 ... ... dependent option set 1 dep1-io0 -> dep1-io1 ... dep1-mem0 -> dep1-mem1 ... ... ... This data structure was designed for ISAPNP, where the OS configures device resource settings by writing directly to configuration registers. The OS can write the registers in arbitrary order much like it writes PCI BARs. However, for PNPBIOS and ACPI devices, the OS uses firmware interfaces that perform device configuration, and it is important to pass the desired settings to those interfaces in the correct order. The OS learns the correct order by using firmware interfaces that return the "current resource settings" and "possible resource settings," but the option structures above doesn't store the ordering information. This patch replaces the independent and dependent lists with a single list of options. For example, a device might have possible resource settings like this: dev options ind-io0 -> dep0-io0 -> dep1->io0 -> ind-io1 ... All the possible settings are in the same list, in the order they come from the firmware "possible resource settings" list. Each entry is tagged with an independent/dependent flag. Dependent entries also have a "set number" and an optional priority value. All dependent entries must be assigned from the same set. For example, the OS can use all the entries from dependent set 0, or all the entries from dependent set 1, but it cannot mix entries from set 0 with entries from set 1. Prior to this patch PNP didn't keep track of the order of this list, and it assigned all independent options first, then all dependent ones. Using the example above, that resulted in a "desired configuration" list like this: ind->io0 -> ind->io1 -> depN-io0 ... instead of the list the firmware expects, which looks like this: ind->io0 -> depN-io0 -> ind-io1 ...

The ISAPNP spec recommends that independent options precede dependent ones, but this is not actually required. The current ISAPNP code incorrectly puts such trailing independent options at the end of the last dependent option list. This patch fixes that bug by resetting the current option list to the independent list when we see an "End Dependent Functions" tag. PNPBIOS and PNPACPI handle this the same way.

This patch adds an IORESOURCE_IRQ_OPTIONAL flag for use when assigning resources to a device. If the flag is set and we are unable to assign an IRQ to the device, we can leave the IRQ disabled but allow the overall resource allocation to succeed. Some devices request an IRQ, but can run without an IRQ (possibly with degraded performance). This flag lets us run the device without the IRQ instead of just leaving the device disabled. This is a reimplementation of this previous change by Rene Herman <rene.herman@gmail.com>: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3b73a223661ed137c5d3d2635f954382e94f5a43 I reimplemented this for two reasons: - to prepare for converting all resource options into a single linked list, as opposed to the per-resource-type lists we have now, and - to preserve the order and number of resource options. In PNPBIOS and ACPI, we configure a device by giving firmware a list of resource assignments. It is important that this list has exactly the same number of resources, in the same order, as the "template" list we got from the firmware in the first place. The problem of a sound card MPU401 being left disabled for want of an IRQ was reported by Uwe Bugla <uwe.bugla@gmx.de>.

ACPI Extended Interrupt Descriptors can encode 32-bit interrupt numbers, so an interrupt number may exceed the size of the bitmap we use to track possible IRQ settings. To avoid corrupting memory, complain and ignore too-large interrupt numbers. There's similar code in pnpacpi_parse_irq_option(), but I didn't change that because the small IRQ descriptor can only encode IRQs 0-15, which do not exceed bitmap size. In the future, we could handle IRQ numbers greater than PNP_IRQ_NR by replacing the bitmap with a table or list.

This patch moves all the option allocations (pnp_mem, pnp_port, etc) into the pnp_register_{mem,port,irq,dma}_resource() functions. This will make it easier to rework the option data structures. The non-trivial part of this patch is the IRQ handling. The backends have to allocate a local pnp_irq_mask_t bitmap, populate it, and pass a pointer to pnp_register_irq_resource().
