[PATCH v3.18-rc3] param: fix crash on bad kernel arguments

by Daniel Thompson

Currently if the user passes an invalid value on the kernel command line then the kernel will crash during argument parsing. On most systems this is very hard to debug because the console hasn't been initialized yet. This is a regression due to commit 51e158c12aca ("param: hand arguments after -- straight to init") which, in response to the systemd debug controversy, made it possible to explicitly pass arguments to init. To achieve this parse_args() was extended from simply returning an error code to returning a pointer. Regretably the new init args logic does not perform a proper validity check on the pointer resulting in a crash. This patch fixes the validity check. Should the check fail then no arguments will be passed to init. This is reasonable and matches how the kernel treats its own arguments (i.e. no error recovery).

[PATCH V2 1/5] sched: idle: cpuidle: Check the latency req before idle

by Daniel Lezcano

When the pmqos latency requirement is set to zero that means "poll in all the cases". That is correctly implemented on x86 but not on the other archs. As how is written the code, if the latency request is zero, the governor will return zero, so corresponding, for x86, to the poll function, but for the others arch the default idle function. For example, on ARM this is wait-for- interrupt with a latency of '1', so violating the constraint. In order to fix that, do the latency requirement check *before* calling the cpuidle framework in order to jump to the poll function without entering cpuidle. That has several benefits: 1. It clarifies and unifies the code 2. It fixes x86 vs other archs behavior 3. Factors out the call to the same function 4. Prevent to enter the cpuidle framework with its expensive cost in calculation As the latency_req is needed in all the cases, change the select API to take the latency_req as parameter in case it is not equal to zero. As a positive side effect, it introduces the latency constraint specified externally, so one more step to the cpuidle/scheduler integration.

[PATCH v7 0/6] arm64: add seccomp support

by AKASHI Takahiro

# Sorry for updating the patch so slowly. This patch series enables secure computing (system call filtering) on arm64, and contains related enhancements and bug fixes. NOTE: This versions contain a workaround against possible BUG_ON() failure at audit_syscall_exit(), but doesn't contain an extra optimization, as I submitted for arm, of excluding syscall enter/exit tracing against invalid system calls due to an issue that I reported in: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-October/292170.h… The code was tested on ARMv8 fast model with 64-bit/32-bit userspace using: * libseccomp v2.1.1 with modifications for arm64, especially its "live" tests: No.20, 21 and 24. * modified version of Kees' seccomp test for 'changing/skipping a syscall' and seccomp() system call * in-house tests for 'changing/skipping a system call' by tracing with ptrace(PTRACE_SYSCALL) (that is, not via seccomp filter)' with and without audit tracing. Changes v6 -> v7: * simplified the condition of checking for user-issued syscall(-1) at syscall_trace_enter() [2/6] * defines __NR_seccomp_sigreturn only if arch-specific def doesn't exist. As Kees suggests, this is necessary for x86 and others. [3/6] * removed "#ifdef __ARCH_SIGSYS" which is always true on arm64. [5/6] * changed to call syscall_trace_exit() even if secure_computing fails. [6/6] In v6, syscall_trace_enter() returns RET_SYSCALL_SKIP_TRACE (== -2) and skips syscall_trace_exit() to minimize the overhead, but this case can be easily confused with user-issued (and invalid) syscall(-2). Anyway, this is now a consistent behavior with arm and other archs. Changes v5 -> v6: * rebased to v3.17-rc * changed the interface of changing/skipping a system call from re-writing x8 register [v5 1/3] to using dedicated PTRACE_SET_SYSCALL command [1/6, 2/6] Patch [1/6] contains a checkpatch error around a switch statement, but it won't be fixed as in compat_arch_ptrace(). * added a new system call, seccomp(), for compat task [4/6] * added SIGSYS siginfo for compat task [5/6] * changed to always execute audit exit tracing to avoid OOPs [2/6, 6/6] Changes v4 -> v5: * rebased to v3.16-rc * add patch [1/3] to allow ptrace to change a system call (please note that this patch should be applied even without seccomp.) Changes v3 -> v4: * removed the following patch and moved it to "arm64: prerequisites for audit and ftrace" patchset since it is required for audit and ftrace in case of !COMPAT, too. "arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h" Changes v2 -> v3: * removed unnecessary 'type cast' operations [2/3] * check for a return value (-1) of secure_computing() explicitly [2/3] * aligned with the patch, "arm64: split syscall_trace() into separate functions for enter/exit" [2/3] * changed default of CONFIG_SECCOMP to n [2/3] Changes v1 -> v2: * added generic seccomp.h for arm64 to utilize it [1,2/3] * changed syscall_trace() to return more meaningful value (-EPERM) on seccomp failure case [2/3] * aligned with the change in "arm64: make a single hook to syscall_trace() for all syscall features" v2 [2/3] * removed is_compat_task() definition from compat.h [3/3] AKASHI Takahiro (6): arm64: ptrace: add PTRACE_SET_SYSCALL arm64: ptrace: allow tracer to skip a system call asm-generic: add generic seccomp.h for secure computing mode 1 arm64: add seccomp syscall for compat task arm64: add SIGSYS siginfo for compat task arm64: add seccomp support arch/arm64/Kconfig | 14 ++++++++++++ arch/arm64/include/asm/compat.h | 7 ++++++ arch/arm64/include/asm/ptrace.h | 8 +++++++ arch/arm64/include/asm/seccomp.h | 25 ++++++++++++++++++++ arch/arm64/include/asm/unistd.h | 3 +++ arch/arm64/include/asm/unistd32.h | 3 ++- arch/arm64/include/uapi/asm/ptrace.h | 1 + arch/arm64/kernel/entry.S | 4 ++++ arch/arm64/kernel/ptrace.c | 42 ++++++++++++++++++++++++++++++++-- arch/arm64/kernel/signal32.c | 6 +++++ include/asm-generic/seccomp.h | 30 ++++++++++++++++++++++++ 11 files changed, 140 insertions(+), 3 deletions(-) create mode 100644 arch/arm64/include/asm/seccomp.h create mode 100644 include/asm-generic/seccomp.h -- 1.7.9.5
