2013-09-19drm/fb-helper: don't sleep for screen unblank when an oops is in progressDaniel Vetter
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.

2013-09-19drm/ttm: fix the tt_populated check in ttm_tt_destroy()Ben Skeggs
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.

2013-09-17tty: disassociate_ctty() sends the extra SIGCONTOleg Nesterov
Starting from v3.10 (probably commit f91e2590410b: "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.

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.

2013-09-16vfs: don't set FILE_CREATED before calling ->atomic_open()Miklos Szeredi
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.

2013-09-16pstore: Adjust buffer size for compression for smaller registered buffersAruna Balakrishnaiah
When backends (ex: efivars) have smaller registered buffers, the big_oops_buf is too big for them as number of repeated occurences in the text captured will be less. What happens is that pstore takes too big a bite from the dmesg log and then finds it cannot compress it enough to meet the backend block size. Patch takes care of adjusting the buffer size based on the registered buffer size. cmpr values have been arrived after doing experiments with plain text for buffers of size 1k - 4k (Smaller the buffer size repeated occurence will be less) and with sample crash log for buffers ranging from 4k - 10k.
