Delay the update of the visible framebuffer console until all other consoles have been initialized in order to avoid losing information. This only seems to be a problem with modules, not with built-in drivers. Signed-off-by:

The drawing functions of atyfb is unecessary syncing the GPU which is affecting performance. Remove the calls, any direct access by fbcon to the framebuffer will always be preceeded by a call to atyfb_sync(). Signed-off-by:

Fix image and color handling in atyfb_cursor() - In the 2-bit scheme of the cursor image, just set the first bit to be always zero (turn off transparency and/or XOR), and just do the masking manually - The cursor color is converted into 32-bit RGBA8888 using struct fb_cmap. Each component in the cmap is u16 in size, so mask the upper 8 bits. Signed-off-by:

nVidia is churning out chipsets like there's no tomorrow. And even though the pci_device_id table now has numerous entries, it is still not guaranteed that all supported devices are included or will be included. Fortunately, nvidiafb has chipset detection logic built in. So, change the contents of the pci_device_id table so it will capture all nVidia devices of the display class. Unsupported chipsets will then be filtered out by nvidiafb's detection logic. Signed-off-by:

The EDID block should specify the display's operating limits (vertical and horizontal sync ranges, and maximum dot clock). If not given by the EDID block, the ranges are extrapolated from the modelist. However, the computation used is only a rough approximation, and the resulting values may not reflect the actual capability of the display. This problem is frequently encountered when the EDID block has a single entry, the single mode entry will fail validation. To prevent this, calculate the values based on the same method used in fb_validate_mode(). Signed-off-by:

Reported by: Rich (Bugzilla Bug 6417) "if savage driver is used in x.org together with savagefb, it results in seriously garbled and distorted screen - coupled with severe slowdowns." This bug is the result of Xorg unable to handle savagefb altering the hardware which results in X failing to start properly and/or failed console switching. Add savagefb_state_save and savagefb_state_restore. These hooks will only save and restore the extended VGA registers. Standard VGA registers will be left alone. This is enough to make savagefb play nicely with the latest Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts may appear before X loads and during console switches). (Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I have to unblank the screen before Xorg loads. So I doubt if the transient screen artifacts will be completely invisible but hopefully it will only be for a shorter duration (not much).) [akpm@osdl.org: cleanups] Signed-off-by:

Allocate space for 2 register states: 'current' for the current state of the hardware, and 'saved', to be used for restoring the hardware to a sane state. This is in preparation for the addition of state save and restore hooks to make savagefb work together with the latest Xorg savage driver. Signed-off-by:

But ide_dump_ata[pi]_status() doesnt do that - it enables interrupts specifically. That is a no-no - what guarantees that another IDE port couldnt generate an IDE interrupt while we are dumping this error? The fix is to turn the irq-enabling in these functions into irq-disabling.

Remove the busproc from pdc202xx_old.c because: - it handles the obsolete HDIO_TRISTATE_HWIF ioctl instead of the modern HDIO_SET_BUSSTATE, so treats its argument wrong; - I don't think that tristating both channels is good idea (probably can't be done otherwise since there seems to be only single bit controlling this).

The function ide_timing_compute() fails to *actually* take drive's specified minimum PIO/DMA cycle times into account -- when doing this, it calls ide_timing_merge() on the 'struct ide_timing' argument which contains garbage at the moment, and then ultimately destroys the read cycle time by quantizing the ide_timing[] entry, instead of copying from that entry to the argument structure, and only then doing a merge/quantize.

This patch optimizes zap_threads() for the case when there are no ->mm users except the current's thread group. In that case we can avoid 'for_each_process()' loop. It also adds a useful invariant: SIGNAL_GROUP_EXIT (if checked under ->siglock) always implies that all threads (except may be current) have pending SIGKILL. Signed-off-by:

This is a preparation for the next patch. No functional changes. Basically, this patch moves '->flags & SIGNAL_GROUP_EXIT' check into zap_threads(), and 'complete(vfork_done)' into coredump_wait outside of ->mmap_sem protected area. Signed-off-by:
-
Oleg Nesterov authored
This patch removes tasklist_lock from zap_threads(). This is safe wrt: do_exit: The caller holds mm->mmap_sem. This means that task which shares the same ->mm can't pass exit_mm(), so it can't be unhashed from init_task.tasks or ->thread_group lists. fork: None of sub-threads can fork after zap_process(leader). All processes which were created before this point should be visible to zap_threads() because copy_process() adds the new process to the tail of init_task.tasks list, and ->siglock lock/unlock provides a memory barrier. de_thread: It does list_replace_rcu(&leader->tasks, ¤t->tasks). So zap_threads() will see either old or new leader, it does not matter. However, it can change p->sighand, so we should use lock_task_sighand() in zap_process(). Signed-off-by:

With this patch zap_process() sets SIGNAL_GROUP_EXIT while sending SIGKILL to the thread group. This means that a TASK_TRACED task 1. Will be awakened by signal_wake_up(1) 2. Can't sleep again via ptrace_notify() 3. Can't go to do_signal_stop() after return from ptrace_stop() in get_signal_to_deliver() So we can remove all ptrace related stuff from coredump path.

With this patch a thread group is killed atomically under ->siglock. This is faster because we can use sigaddset() instead of force_sig_info() and this is used in further patches. Signed-off-by:

zap_threads() iterates over all threads to find those ones which share current->mm. All threads in the thread group share the same ->mm, so we can skip entire thread group if it has another ->mm. This patch shifts the killing of thread group into the newly added zap_process() function. This looks as unnecessary complication, but it is used in further patches. Signed-off-by:

Below is a patch to add a new /proc/self/attr/sockcreate A process may write a context into this interface and all subsequent sockets created will be labeled with that context. This is the same idea as the fscreate interface where a process can specify the label of a file about to be created. At this time one envisioned user of this will be xinetd. It will be able to better label sockets for the actual services. At this time all sockets take the label of the creating process, so all xinitd sockets would just be labeled the same. I tested this by creating a tcp sender and listener. The sender was able to write to this new proc file and then create sockets with the specified label. I am able to be sure the new label was used since the avc denial messages kicked out by the kernel included both the new security permission setsockcreate and all the socket denials were for the new label, not the label of the running process.
