Make the kernel jump into gdbstub (if configured) on a BUG with the register set from the BUG rather than interpolating another illegal instruction and leaving gdbstub's idea of the process counter in unsupported_syscall() where the original BUG was detected. With this patch, gdbstub reports a SIGABRT to the compiler and reports the program counter at the original BUG, allowing the execution state at the time of the BUG to be examined with GDB.

When mthca_fmr_alloc() returns an error, it should free the MPT at the index key, not mr->ibmr.lkey, since the lkey has been mangled by hw_index_to_key() and no longer is the real index.

Commit efcd9971 ("IPoIB/cm: Factor out ipoib_cm_free_rx_reap_list()") introduced a bug in ipoib_cm_dev_stop() when the receive drain times out. In that case, the function moves all the pending rx stuff into a private list but then calls ipoib_cm_free_rx_reap_list(), which handles a different list. Fix this by moving everything to the rx_reap_list that will actually get freed up. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=906>.

Linus Torvalds authored
This reverts commit 1f84260c, which is suspected to be the reason for some very occasional and hard-to-trigger crashes that usually look related to memory allocation (mostly reported in networking, but since that's generally the most common source of shortlived allocations - and allocations in interrupt contexts - that in itself is not a big clue). See for example http://bugzilla.kernel.org/show_bug.cgi?id=9973 http://lkml.org/lkml/2008/2/19/278 etc. One promising suspicion for what the root cause of bug is (which also explains why it's so hard to trigger in practice) came from Eric Dumazet: "I wonder how SLUB_FASTPATH is supposed to work, since it is affected by a classical ABA problem of lockless algo. cmpxchg_local(&c->freelist, object, object[c->offset]) can succeed, while an interrupt came (on this cpu), and several allocations were done, and one free was performed at the end of this interruption, so 'object' was recycled. c->freelist can then contain the previous value (object), but object[c->offset] was changed by IRQ. We then put back in freelist an already allocated object." but another reason for the revert is simply that everybody agrees that this code was the main suspect just by virtue of the pattern of oopses.

So far flush_cache_range() did't consider the I-cache largely because it did rarely ever matter to real world code. This was working primarily because normally code and data are don't share the same pages - with the exception of MIPS16 code which uses address constants embedded between the code. The following sequence of events may break the code: o MIPS16 executable being loaded o dynamic linker relocates the address constants embedded into the code: o Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE o Performs the actual relocations by writing to the pages which likely are COW. Because no PROT_EXEC is set I-cache coherence will not be considered. o Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC. This results in a call to flush_cache_range() which also does not consider I-caches. o => executing the page just having been relocated may now result in the I-cache getting refilled with stale data from memory.

Smack uses CIPSO labeling, but allows for unlabeled packets by specifying an "ambient" label that is applied to incoming unlabeled packets. Because the other end of the connection may dislike IP options, and ssh is one know application that behaves thus, it is prudent to respond in kind. This patch changes the network labeling behavior such that an outgoing packet that would be given a CIPSO label that matches the ambient label is left unlabeled. An "unlbl" domain is added and the netlabel defaulting mechanism invoked rather than assuming that everything is CIPSO. Locking has been added around changes to the ambient label as the mechanisms used to do so are more involved.

This patch teaches page_is_ram() about the fact that the first 4Kb of memory are special on x86, even though the E820 table normally doesn't exclude it. This fixes the WARN_ON() reported by Laurent Riffard who was also very helpful in diagnosing the issue.
