2008-10-30nfsd: fix vm overcommit crashAlan Cox
Junjiro R. Okajima reported a problem where knfsd crashes if you are using it to export shmemfs objects and run strict overcommit. In this situation the current->mm based modifier to the overcommit goes through a NULL pointer. We could simply check for NULL and skip the modifier but we've caught other real bugs in the past from mm being NULL here - cases where we did need a valid mm set up (eg the exec bug about a year ago). To preserve the checks and get the logic we want shuffle the checking around and add a new helper to the vm_ security wrappers Also fix a current->mm reference in nommu that should use the passed mm [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: fix build] Reported-by: Junjiro R.

2008-10-30ipmi: add MODULE_ALIAS to load ipmi_devintf with ipmi_siScott James Remnant
The ipmi_devintf module contains the userspace interface for IPMI devices, yet will not be loaded automatically with a system interface handler driver. Add a MODULE_ALIAS for the "platform:ipmi_si" MODALIAS exported by the ipmi_si driver, so that userspace knows of the recommendation.

For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is specified. This eliminates a dependency of the XP/XPC drivers on having the GRU driver insmod'd in order to insmod them, when running on an ia64-sn2 system. On such a system the GRU driver serves no useful purpose.

Earlier attempt to fix this was discussed at: http://lkml.org/lkml/2008/7/23/148 As suggested by Oleg Nesterov in that thread, use "task_pid_vnr() > 1" check since task_pid_vnr() returns 0 if process is outside the caller's namespace.

2008-10-30ecryptfs: fix memory corruption when storing crypto info in xattrsEric Sandeen
When ecryptfs allocates space to write crypto headers into, before copying it out to file headers or to xattrs, it looks at the value of crypt_stat->num_header_bytes_at_front to determine how much space it needs. This is also used as the file offset to the actual encrypted data, so for xattr-stored crypto info, the value was zero. So, we kzalloc'd 0 bytes, and then ran off to write to that memory. (Which returned as ZERO_SIZE_PTR, so we explode quickly). The right answer is to always allocate a page to write into; the current code won't ever write more than that (this is enforced by the (PAGE_CACHE_SIZE - offset) length in the call to ecryptfs_generate_key_packet_set). To be explicit about this, we now send in a "max" parameter, rather than magically using PAGE_CACHE_SIZE there. Also, since the pointer we pass down the callchain eventually gets the virt_to_page() treatment, we should be using a alloc_page variant, not kzalloc (see also 7fcba054373d5dfc43d26e243a5c9b92069972ee) Signed-off-by: Eric Sandeen <sandeen@redhat.com> Acked-by: Michael Halcrow <mhalcrow@us.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

By default, non-privileged tasks can only mlock() a small amount of memory to avoid a DoS attack by ordinary users. The Linux kernel defaulted to 32k (on a 4k page size system) to accommodate the needs of gpg. However, newer gpg2 needs 64k in various circumstances and otherwise fails miserably, see bnc#329675. Change the default to 64k, and make it more agnostic to PAGE_SIZE.

2008-10-28ftrace: fix current_tracer error returnSteven Rostedt
The commit (in linux-tip) c2931e05ec5965597cbfb79ad332d4a29aeceb23 ( ftrace: return an error when setting a nonexistent tracer ) added useful code that would error when a bad tracer was written into the current_tracer file. But this had a bug if the amount written was more than the amount read by that code. The first iteration would set the tracer correctly, but since it did not consume the rest of what was written (usually whitespace), the userspace utility would continue to write what was not consumed. This second iteration would fail to find a tracer and return -EINVAL. Funny thing is that the tracer would have already been set. This patch just consumes all the data that is written to the file.

2008-10-28KVM: Fix guest shared interrupt with in-kernel irqchipSheng Yang
Every call of kvm_set_irq() should offer an irq_source_id, which is allocated by kvm_request_irq_source_id(). Based on irq_source_id, we identify the irq source and implement logical OR for shared level interrupts. The allocated irq_source_id can be freed by kvm_free_irq_source_id(). Currently, we support at most sizeof(unsigned long) different irq sources.

2008-10-28lockdep: fix irqs on/off ip tracingHeiko Carstens
Impact: fix lockdep lock-api-caller output when irqsoff tracing is enabled 81d68a96 "ftrace: trace irq disabled critical timings" added wrappers around trace_hardirqs_on/off_caller. However these functions use __builtin_return_address(0) to figure out which function actually disabled or enabled irqs. The result is that we save the ips of trace_hardirqs_on/off instead of the real caller. Not very helpful. However since the patch from Steven the ip already gets passed. So use that and get rid of __builtin_return_address(0) in these two functions. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
