These are patterned after the node_to_cpumask_ptr macros. In general terms, if there is a cpumask_of_cpu_map[] then a pointer to the cpumask_of_cpu_map[cpu] entry is used. The cpumask_of_cpu_map is provided when there is a large NR_CPUS count, reducing greatly the amount of code generated and stack space used for cpumask_of_cpu(). The pointer to the cpumask_t value is needed for calling set_cpus_allowed_ptr() to reduce the amount of stack space needed to pass the cpumask_t value. If there isn't a cpumask_of_cpu_map[], then a temporary variable is declared and filled in with value from cpumask_of_cpu(cpu) as well as a pointer variable pointing to this temporary variable. Afterwards, the pointer is used to reference the cpumask value. The compiler will optimize out the extra dereference through the pointer as well as the stack space used for the pointer, resulting in identical code. A good example of the orthogonal usages is in net/sunrpc/svc.c: case SVC_POOL_PERCPU: { unsigned int cpu = m->pool_to[pidx]; cpumask_of_cpu_ptr(cpumask, cpu); *oldmask = current->cpus_allowed; set_cpus_allowed_ptr(current, cpumask); return 1; } case SVC_POOL_PERNODE: { unsigned int node = m->pool_to[pidx]; node_to_cpumask_ptr(nodecpumask, node); *oldmask = current->cpus_allowed; set_cpus_allowed_ptr(current, nodecpumask); return 1; } Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> |

Also change the parameters, and the function name slightly. This is required since there aren't any struct pages available in early boot code, and renaming of functions is done to make sure that all users are converted to the new API. Instead of a pointer to a struct page a virtual address is passed, and instead of an order the number of pages for which the page state needs be set.

H A D | core.c | diff f5d03da4 Tue Jan 02 16:33:45 MST 2024 Jinghao Jia <jinghao7@illinois.edu> x86/kprobes: fix incorrect return address calculation in kprobe_emulate_call_indirect kprobe_emulate_call_indirect currently uses int3_emulate_call to emulate indirect calls. However, int3_emulate_call always assumes the size of the call to be 5 bytes when calculating the return address. This is incorrect for register-based indirect calls in x86, which can be either 2 or 3 bytes depending on whether REX prefix is used. At kprobe runtime, the incorrect return address causes control flow to land onto the wrong place after return -- possibly not a valid instruction boundary.

However, int3_emulate_call always assumes the size of the call to be 5 bytes when calculating the return address. This is incorrect for register-based indirect calls in x86, which can be either 2 or 3 bytes depending on whether REX prefix is used. At kprobe runtime, the incorrect return address causes control flow to land onto the wrong place after return -- possibly not a valid instruction boundary.

However, int3_emulate_call always assumes the size of the call to be 5 bytes when calculating the return address. This is incorrect for register-based indirect calls in x86, which can be either 2 or 3 bytes depending on whether REX prefix is used. At kprobe runtime, the incorrect return address causes control flow to land onto the wrong place after return -- possibly not a valid instruction boundary. This can lead to a panic like the following: [ 7.308204][ C1] BUG: unable to handle page fault for address: 000000000002b4d8 [ 7.308883][ C1] #PF: supervisor read access in kernel mode [ 7.309168][ C1] #PF: error_code(0x0000) - not-present page [ 7.309461][ C1] PGD 0 P4D 0 [ 7.309652][ C1] Oops: 0000 [#1] SMP [ 7.309929][ C1] CPU: 1 PID: 0 Comm: swapper/1 Not tainted 6.7.0-rc5-trace-for-next #6 [ 7.310397][ C1] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.0-20220807_005459-localhost 04/01/2014 [ 7.311068][ C1] RIP: 0010:__common_interrupt+0x52/0xc0 [ 7.311349][ C1] Code: 01 00 4d 85 f6 74 39 49 81 fe 00 f0 ff ff 77 30 4c 89 f7 4d 8b 5e 68 41 ba 91 76 d8 42 45 03 53 fc 74 02 0f 0b cc ff d3 65 48 <8b> 05 30 c7 ff 7e 65 4c 89 3d 28 c7 ff 7e 5b 41 5c 41 5e 41 5f c3 [ 7.312512][ C1] RSP: 0018:ffffc900000e0fd0 EFLAGS: 00010046 [ 7.312899][ C1] RAX: 0000000000000001 RBX: 0000000000000023 RCX: 0000000000000001 [ 7.313334][ C1] RDX: 00000000000003cd RSI: 0000000000000001 RDI: ffff888100d302a4 [ 7.313702][ C1] RBP: 0000000000000001 R08: 0ef439818636191f R09: b1621ff338a3b482 [ 7.314146][ C1] R10: ffffffff81e5127b R11: ffffffff81059810 R12: 0000000000000023 [ 7.314509][ C1] R13: 0000000000000000 R14: ffff888100d30200 R15: 0000000000000000 [ 7.314951][ C1] FS: 0000000000000000(0000) GS:ffff88813bc80000(0000) knlGS:0000000000000000 [ 7.315396][ C1] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 7.315691][ C1] CR2: 000000000002b4d8 CR3: 0000000003028003 CR4: 0000000000370ef0 [ 7.316153][ C1] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 7.316508][ C1] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 7.316948][ C1] Call Trace: [ 7.317123][ C1] <IRQ> [ 7.317279][ C1] ?

First of all we do not want to change existing behavior when intercepting AP instructions without the SIE allowing the guest to use AP instructions. In this patch we only handle the AQIC interception allowed by facility 65 which will be enabled when the complete interception infrastructure will be present. We add a callback inside the KVM arch structure for s390 for a VFIO driver to handle a specific response to the PQAP instruction with the AQIC command and only this command. But we want to be able to return a correct answer to the guest even there is no VFIO AP driver in the kernel. Therefor, we inject the correct exceptions from inside KVM for the case the callback is not initialized, which happens when the vfio_ap driver is not loaded. We do consider the responsibility of the driver to always initialize the PQAP callback if it defines queues by initializing the CRYCB for a guest. If the callback has been setup we call it. If not we setup an answer considering that no queue is available for the guest when no callback has been setup.
