Remove all ifdefs from topology code and also only compile it for the CONFIG_SCHED_BOOK case. The new code selects SCHED_MC if SCHED_BOOK is selected. SCHED_MC without SCHED_BOOK is not possible anymore. Furthermore various sysfs attributes are not available anymore for the !SCHED_BOOK case. In particular all attributes that correspond to CPU polarization. But since all real world kernels have SCHED_BOOK selected anyway this doesn't matter too much.

Currently, when smp_switch_to_ipl_cpu() is done, the backchain in the dump analysis tool crash looks like the following: #0 [1f746e70] __machine_kexec at 11dd92 #1 [1f746eb8] smp_restart_cpu at 11820e #0 [00907eb0] cpu_idle at 10602e #1 [00907ef8] start_kernel at 979a08 It would be good to see the registers of the interrupted function. To achieve this, the backchain on the new stack has to be set to zero. This looks then like the following: #0 [1f746e70] __machine_kexec at 11dd8e #1 [1f746eb8] smp_restart_cpu at 11820a PSW: 0706000180000000 00000000005c6fe6 (vtime_stop_cpu+134) GPRS: 0000000000000000 00000000005c6fe6 0000000001ad0228 0000000001ad0248 0000000000907f08 0000000001ad0b40 0000000000979344 0000000000000000 00000000009c0000 00000000009c0010 00000000009ab024 0000000001ad0200 0000000001ad0238 00000000005cc9d8 000000000010602e 0000000000907e68 #0 [00907eb0] cpu_idle at 10602e #1 [00907ef8] start_kernel at 979a08 In addition to this, now also the correct PSW is stored in the pt_regs structure that is located at the start of the panic stack.

The kernel address space of a 64 bit kernel currently uses a three level page table and the vmemmap array has a fixed address and a fixed maximum size. A three level page table is good enough for systems with less than 3.8TB of memory, for bigger systems four page table levels need to be used. Each page table level costs a bit of performance, use 3 levels for normal systems and 4 levels only for the really big systems. To avoid bloating sparse.o too much set MAX_PHYSMEM_BITS to 46 for a maximum of 64TB of memory. Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

The current code in setup_boot_command_line() uses a heuristic to detect an EBCDIC command line. It checks if any of the bytes in the command line has bit one (0x80) set. In that case it is assumed that we have an EBCDIC string and the complete command line is converted. On s390 there are cases where the boot loader provides a kernel command line that is NULL terminated, but has random data after the NULL termination. In that case, setup_boot_command_line() might misinterpret an ASCII string for an EBCDIC string. A subsequent string conversion can then damage the ASCII string. This patch solves the problem by checking for NULL termination. If no EBCDIC character has been found until the the NULL termination has been found, we now assume that we have an ASCII string.

Bruce Fields notes that commit 778fc546 ("locks: fix tracking of inprogress lease breaks") introduced a possible error pointer dereference on failure to allocate memory. locks_conflict() will dereference the passed-in new lease lock structure that may be an error pointer. This means an open (without O_NONBLOCK set) on a file with a lease applied (generally only done when Samba or nfsd (with v4) is running) could crash if a kmalloc() fails. So instead of playing games with IS_ERROR() all over the place, just check the allocation failure early. That makes the code more straightforward, and avoids this possible bad pointer dereference.

Unlike all of the other cpuid bits, the TSC deadline timer bit is set unconditionally, regardless of what userspace wants. This is broken in several ways: - if userspace doesn't use KVM_CREATE_IRQCHIP, and doesn't emulate the TSC deadline timer feature, a guest that uses the feature will break - live migration to older host kernels that don't support the TSC deadline timer will cause the feature to be pulled from under the guest's feet; breaking it - guests that are broken wrt the feature will fail. Fix by not enabling the feature automatically; instead report it to userspace. Because the feature depends on KVM_CREATE_IRQCHIP, which we cannot guarantee will be called, we expose it via a KVM_CAP_TSC_DEADLINE_TIMER and not KVM_GET_SUPPORTED_CPUID. Fixes the Illumos guest kernel, which uses the TSC deadline timer feature.

Only allow KVM device assignment to attach to devices which: - Are not bridges - Have BAR resources (assume others are special devices) - The user has permissions to use Assigning a bridge is a configuration error, it's not supported, and typically doesn't result in the behavior the user is expecting anyway. Devices without BAR resources are typically chipset components that also don't have host drivers. We don't want users to hold such devices captive or cause system problems by fencing them off into an iommu domain. We determine "permission to use" by testing whether the user has access to the PCI sysfs resource files. By default a normal user will not have access to these files, so it provides a good indication that an administration agent has granted the user access to the device.

"! --connbytes 23:42" should match if the packet/byte count is not in range. As there is no explict "invert match" toggle in the match structure, userspace swaps the from and to arguments (i.e., as if "--connbytes 42:23" were given). However, "what <= 23 && what >= 42" will always be false. Change things so we use "||" in case "from" is larger than "to". This change may look like it breaks backwards compatibility when "to" is 0. However, older iptables binaries will refuse "connbytes 42:0", and current releases treat it to mean "! --connbytes 0:42", so we should be fine.

NF_HOOK.constprop.4+0x56/0x56 [bridge] This is caused by bridge netfilter special dst_entry (fake_rtable), a special shared entry, where attaching an inetpeer makes no sense. Problem is present since commit 87c48fa3 (ipv6: make fragment identifications less predictable) Introduce DST_NOPEER dst flag and make sure ipv6_select_ident() and __ip_select_ident() fallback to the 'no peer attached' handling.

Userspace may not provide TCA_OPTIONS, in fact tc currently does so not do so if no arguments are specified on the command line. Return EINVAL instead of panicing. Signed-off-by: NThomas Graf <tgraf@redhat.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Commit 618f9bc7 (net: Move mtu handling down to the protocol depended handlers) forgot the bridge netfilter case, adding a NULL dereference in ip_fragment().
