Otherwise the system will burn even brighter and worse, leave the user wondering what's going on exactly. Since we already have a panic handler which will (try) to restore the entire fbdev console mode, we can just bail out. Inspired by a patch from Konstantin Khlebnikov. The callchain leading to this, cut&pasted from Konstantin's original patch: callstack: panic() bust_spinlocks(1) unblank_screen() vc->vc_sw->con_blank() fbcon_blank() fb_blank() info->fbops->fb_blank() drm_fb_helper_blank() drm_fb_helper_dpms() drm_modeset_lock_all() mutex_lock(&dev->mode_config.mutex) Note that the entire locking in the fb helper around panic/sysrq and kdbg is ... non-existant. So we have a decent change of blowing up everything. But since reworking this ties in with funny concepts like the fbdev notifier chain or the impressive things which happen around console_lock while oopsing, I'll leave that as an exercise for braver souls than me.

After a vmalloc failure in ttm_dma_tt_alloc_page_directory(), ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up inside the driver's unpopulate() hook when populate() has never yet been called. On nouveau, the first issue to be hit because of this is that dma_address[] may be a NULL pointer. After working around this, ttm_pool_unpopulate() may potentially hit the same issue with the pages[] array. It seems to make more sense to avoid calling unpopulate on already unpopulated TTMs than to add checks to all the implementations. Signed-off-by:

Starting from v3.10 (probably commit f91e2590: "tty: Signal foreground group processes in hangup") disassociate_ctty() sends SIGCONT if tty && on_exit. This breaks LSB test-suite, in particular test8 in _exit.c and test40 in sigcon5.c. Put the "!on_exit" check back to restore the old behaviour. Review by Peter Hurley: "Yes, this regression was introduced by me in that commit. The effect of the regression is that ptys will receive a SIGCONT when, in similar circumstances, ttys would not. The fact that two test vectors accidentally tripped over this regression suggests that some other apps may as well. Thanks for catching this" Cc: stable@vger.kernel.org # v3.10+ Signed-off-by:

Page tables in a read-only memory slot will currently cause a triple fault because the page walker uses gfn_to_hva and it fails on such a slot. OVMF uses such a page table; however, real hardware seems to be fine with that as long as the accessed/dirty bits are set. Save whether the slot is readonly, and later check it when updating the accessed and dirty bits. Reviewed-by:

Miklos Szeredi authored
If O_CREAT|O_EXCL are passed to open, then we know that either - the file is successfully created, or - the operation fails in some way. So previously we set FILE_CREATED before calling ->atomic_open() so the filesystem doesn't have to. This, however, led to bugs in the implementation that went unnoticed when the filesystem didn't check for existence, yet returned success. To prevent this kind of bug, require filesystems to always explicitly set FILE_CREATED on O_CREAT|O_EXCL and verify this in the VFS. Also added a couple more verifications for the result of atomic_open(): - Warn if filesystem set FILE_CREATED despite the lack of O_CREAT. - Warn if filesystem set FILE_CREATED but gave a negative dentry.

Set FILE_CREATED on O_CREAT|O_EXCL. If the NFS server honored our request for exclusivity then this must be correct. Currently this is a no-op, since the VFS sets FILE_CREATED anyway. The next patch will, however, require this flag to be always set by filesystems. Signed-off-by:
