* microblaze: Fix syscall error recovery for invalid syscall IDsJamie Garside2015-03-041-1/+2
| | | | | | | | | | | | | | | | | | | This patch fixes two bugs in the Microblaze syscall trap handler when an invalid syscall ID is used. First, the range check on line 351 only checks for syscall IDs greater than __NR_syscalls. A negative syscall ID (either passed to `syscall()` or as returned by `do_syscall_trace_enter()` on error) will still satisfy this test and cause the Linux kernel to access an invalid memory location and cause a kernel oops. This has been fixed by also checking for r12 < 0. Secondly, the current error recovery at line 378 returns using the wrong register (r15 instead of r14) and does not restore the previous stack state. This has been fixed by invoking `ret_from_trap` on error, setting r3 to `-ENOSYS`, similar to what would happen when calling a valid syscall.

* all arches, signal: move restart_block to struct task_structAndy Lutomirski2015-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an attacker can cause a controlled kernel stack overflow, overwriting the restart block is a very juicy exploit target. This is because the restart_block is held in the same memory allocation as the kernel stack. Moving the restart block to struct task_struct prevents this exploit by making the restart_block harder to locate. Note that there are other fields in thread_info that are also easy targets, at least on some architectures. It's also a decent simplification, since the restart code is more or less identical on all architectures.

From Alexander Duyck. 3) Remove sock_iocb altogether, from CHristoph Hellwig. 4) Allow congestion control algorithm selection via routing metrics. From Daniel Borkmann. 5) Make ipv4 uncached route list per-cpu, from Eric Dumazet. 6) Handle rfs hash collisions more gracefully, also from Eric Dumazet. 7) Add xmit_more support to r8169, e1000, and e1000e drivers.

From Neal Cardwell. 13) Various rhashtable bug fixes and enhancements, from Herbert Xu, Patrick McHardy, and Thomas Graf. 14) Support xmit_more in be2net, from Sathya Perla. 15) Group Policy extensions for vxlan, from Thomas Graf. 16) Remove Checksum Offload support for vxlan, from Tom Herbert. 17) Like ipv4, support lockless transmit over ipv6 UDP sockets.

| | | | | | | | | | | | | | | When running in non-cache coherent configuration the memory that was allocated with dma_alloc_coherent() has a custom mapping and so there is no 1-to-1 relationship between the kernel virtual address and the PFN. This means that virt_to_pfn() will not work correctly for those addresses and the default mmap implementation in the form of dma_common_mmap() will map some random, but not the requested, memory area. Fix this by providing a custom mmap implementation that looks up the PFN from the page table rather than using virt_to_pfn.

We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static.

* | microblaze: ftrace: Add call to ftrace_graph_is_dead() in function graph codeSteven Rostedt (Red Hat)2014-07-181-0/+3
|/ | | | | | | | | | | | | | | | | ftrace_stop() is going away as it disables parts of function tracing that affects users that should not be affected. But ftrace_graph_stop() is built on ftrace_stop(). Here's another example of killing all of function tracing because something went wrong with function graph tracing. Instead of disabling all users of function tracing on function graph error, disable only function graph tracing. To do this, the arch code must call ftrace_graph_is_dead() before it implements function graph.
