The caps revocation should either initiate writeback, invalidateion, or call check_caps to ack or do the dirty work. The primary question is whether we can get away with only checking the auth cap or whether all caps need to be checked. The old code was doing...something else. At the very least, revocations from non-auth MDSs could break by triggering the "check auth cap only" case. Signed-off-by:

Debian's ia64 autobuilders have been seeing kernel freeze or reboot when running the gdb testsuite (Debian bug 588574): dannf bisected to 2.6.32 62eede62 "mm: ZERO_PAGE without PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target. I'd missed updating the gate_vma handling in __get_user_pages(): that happens to use vm_normal_page() (nowadays failing on the zero page), yet reported success even when it failed to get a page - boom when access_process_vm() tried to copy that to its intermediate buffer. Fix this, resisting cleanups: in particular, leave it for now reporting success when not asked to get any pages - very probably safe to change, but let's not risk it without testing exposure. Why did ia64 crash with 16kB pages, but succeed with 64kB pages? Because setup_gate() pads each 64kB of its gate area with zero pages. Reported-by:

I was testing two CyberPro 2000 based PCI cards on x86 and the machine always hanged completely when the cyber2000fb module was loaded. It seems that the card hangs when some registers are accessed too quickly after writing RAMDAC control register. With this patch, both card work. Add delay after RAMDAC control register write to prevent hangs on module load. Signed-off-by:

__sa1111_remove always frees its argument, so the subsequent reference to sachip->saved_state represents a use after free. __sa1111_remove does not appear to use the saved_state field, so the patch simply frees it first. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E,E2; @@ __sa1111_remove(E) ...

smp_processor_id() must not be called from a preemptible context (this is checked by CONFIG_DEBUG_PREEMPT). kmap_high_l1_vipt() was doing so. This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth could be incremented, causing a BUG_ON(*depth <= 0); in kunmap_high_l1_vipt(). The solution is to move the call to smp_processor_id() after the call to preempt_disable(). Originally by: Andrew Howe <ahowe@nvidia.com> Signed-off-by:

In root_nfs_name() it does the following: if (strlen(buf) + strlen(cp) > NFS_MAXPATHLEN) { printk(KERN_ERR "Root-NFS: Pathname for remote directory too long.\n"); return -1; } sprintf(nfs_export_path, buf, cp); In the original code if (strlen(buf) + strlen(cp) == NFS_MAXPATHLEN) then the sprintf() would lead to an overflow. Generally the rest of the code assumes that the path can have NFS_MAXPATHLEN (1024) characters and a NUL terminator so the fix is to add space to the nfs_export_path[] buffer. Signed-off-by:

Fix __task_cred()'s lockdep check by removing the following validation condition: lockdep_tasklist_lock_is_held() as commit_creds() does not take the tasklist_lock, and nor do most of the functions that call it, so this check is pointless and it can prevent detection of the RCU lock not being held if the tasklist_lock is held. Instead, add the following validation condition: task->exit_state >= 0 to permit the access if the target task is dead and therefore unable to change its own credentials. Fix __task_cred()'s comment to: (1) discard the bit that says that the caller must prevent the target task from being deleted. That shouldn't need saying. (2) Add a comment indicating the result of __task_cred() should not be passed directly to get_cred(), but rather than get_task_cred() should be used instead. Also put a note into the documentation to enforce this point there too. Signed-off-by:
