| * audit: inline audit_syscall_entry to reduce burden on archsEric Paris2012-01-171-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Every arch calls: if (unlikely(current->audit_context)) audit_syscall_entry() which requires knowledge about audit (the existance of audit_context) in the arch code. Just do it all in static inline in audit.h so that arch's can remain blissfully ignorant. Signed-off-by: Eric Paris <eparis@redhat.com>
| * Audit: push audit success and retcode into arch ptrace.hEric Paris2012-01-172-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The audit system previously expected arches calling to audit_syscall_exit to supply as arguments if the syscall was a success and what the return code was. Audit also provides a helper AUDITSC_RESULT which was supposed to simplify things by converting from negative retcodes to an audit internal magic value stating success or failure. This helper was wrong and could indicate that a valid pointer returned to userspace was a failed syscall. The fix is to fix the layering foolishness. We now pass audit_syscall_exit a struct pt_reg and it in turns calls back into arch code to collect the return value and to determine if the syscall was a success or failure. We also define a generic is_syscall_success() macro which determines success/failure based on if the value is < -MAX_ERRNO. This works for arches like x86 which do not use a separate mechanism to indicate syscall failure. We make both the is_syscall_success() and regs_return_value() static inlines instead of macros. The reason is because the audit function must take a void* for the regs. (uml calls theirs struct uml_pt_regs instead of just struct pt_regs so audit_syscall_exit can't take a struct pt_regs). Since the audit function takes a void* we need to use static inlines to cast it back to the arch correct structure to dereference it. The other major change is that on some arches, like ia64, MIPS and ppc, we change regs_return_value() to give us the negative value on syscall failure. THE only other user of this macro, kretprobe_example.c, won't notice and it makes the value signed consistently for the audit functions across all archs. In arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old audit code as the return value. But the ptrace_64.h code defined the macro regs_return_value() as regs[3]. I have no idea which one is correct, but this patch now uses the regs_return_value() function, so it now uses regs[3]. For powerpc we previously used regs->result but now use the regs_return_value() function which uses regs->gprs[3]. regs->gprs[3] is always positive so the regs_return_value(), much like ia64 makes it negative before calling the audit code when appropriate.

| * | | [S390] disassembler: mark exception causing instructionsHeiko Carstens2011-12-271-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an exception happens the PSW either points to the instruction that caused the exception or to the instruction that follows the exception causing instruction, depending on the exception type. Since the inkernel disassembler adds a ">" in front of the disassembly many people assume incorrectly that the instruction that is pointed to must be the cause of the exception. To make people aware that this is not necessarily the case add a different character in front of the disassembled instruction that precedes the current instructions. The output now looks like this: Krnl PSW : 0704200180000000 0000000000120de8 (test_function+0x0/0x100) R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:0 CC:2 PM:0 EA:3 Krnl GPRS: 000003ff00000000 0000000000120de4 000000000091bb40 0000000000000001 000003fffd2ea000 0000000030fb7df8 0000000030fb7f10 000003ffffa113c8 000000000091bb40 000003fffd2ea000 0000000000000002 0000000030fb7f10 000000003f290240 0000000000606220 00000000002cfb5c 0000000030fb7d58 Krnl Code: 0000000000120ddc: b90400a9 lgr %r10,%r9 0000000000120de0: a7f4ff88 brc 15,120cf0 #0000000000120de4: a7f40001 brc 15,120de6 >0000000000120de8: a7f13f80 tmll %r15,16256 0000000000120dec: eb8ff0580024 stmg %r8,%r15,88(%r15) 0000000000120df2: a7840001 brc 8,120df4 0000000000120df6: b90400ef lgr %r14,%r15 0000000000120dfa: a7fbffb8 aghi %r15,-72 Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The panic function will first print the panic message to the console, then stop additional cpus with smp_send_stop and finally call the function on the panic notifier list. In case of an I/O based console the panic message will cause I/O to be started and a function on the panic notifier list will wait for the completion of the I/O. That does not work if an I/O completion interrupt has already been delivered to a cpu that is then stopped by smp_send_stop.

| * | | [S390] kernel: Fix smp_switch_to_ipl_cpu() stack frame setupMichael Holzheu2011-12-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Martin Schwidefsky <schwidefsky@de.ibm.com>

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.

The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.
