2006-09-01[PATCH] IPMI: fix occasional oops on module unloadCorey Minyard1-0/+1
Olaf Kirch of SuSE tracked down a problem where module unloads of the IPMI driver would occasionally result in Oopses. He tracked that down to a variable that wasn't always initialized properly in some situations. This patch initializes that variable. Olaf sent a patch that kzalloc-ed the data, but this structure is large enough that I would perfer to not do that. Thanks Olaf!

2006-08-27[PATCH] Fix tty layer DoS and comment relevant codeAlan Cox1-10/+79
Unlike the other tty comment patch this one has code changes. Specifically it limits the queue size for a tty to 64K characters (128Kbytes) worst case even if the tty is ignoring tty->throttle. This is because certain drivers don't honour the throttle value correctly, although it is a useful safeguard anyway.

2006-08-27[PATCH] vcsa attribute bits -> ioctl(VT_GETHIFONTMASK)Samuel Thibault1-0/+2
When reading /dev/vcsa while a font with more than 256 characters is loaded, one of the attribute bits records the 9th bit of the character. But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure).

2006-08-27[PATCH] char/moxa.c: fix endianess and multiple-card issuesDirk Eibach1-2/+6
While testing Moxa C218T/PCI on PowerPC 405EP I found that loading firmware using the linux kernel driver fails because calculation of the checksum is not endianess independent in the original code. After I fixed this I found that uploading firmware in a system with multiple cards causes a kernel oops. I had a look in the recent moxa sources and found that they do some kind of locking there. Applying this lock fixed the problem. Alan sayeth: Checksum changes are clearly correct. Other changes is an improvement but not I think enough to handle malicious firmware attacks. That said such an attacker has CAP_SYS_RAWIO anyway so that part is irrelevant except for neatness.

2006-08-06[PATCH] pSeries: hvsi char driver janitorial cleanupLinas Vepstas1-4/+1
A set of tty line discipline cleanup patches were introduced before the dawn of time, in kernel version 2.4.21. This patch performs that cleanup for the hvsi driver. The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was originally written by Hollis Blanchard, who has delegated maintainership to me.

2006-07-11[PATCH] snsc: switch from force_sig to kill_procChristoph Hellwig1-14/+1
Currently the snsc driver uses force_sig to send init a SIGPWR when the system overheats. This patch switches it to kill_proc instead which has the following advantages: (1) gets rid of one of the last remaining tasklist_lock users in modular code (2) simplifies the snsc code significantly The downside is that an init implementation could in theory block SIGPWR and it would not get delivered. The sysvinit code used by all major distributions doesn't do this and blocking this signal in init would be a rather stupid thing to do.

2006-07-11[PATCH] make valid_mmap_phys_addr_range() take a pfnLennert Buytenhek1-2/+2
Newer ARMs have a 40 bit physical address space, but mapping physical memory above 4G needs a special page table format which we (currently?) do not use for userspace mappings, so what happens instead is that mapping an address >= 4G will happily discard the upper bits and wrap. There is a valid_mmap_phys_addr_range() arch hook where we could check for >= 4G addresses and deny the mapping, but this hook takes an unsigned long address: static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size); And drivers/char/mem.c:mmap_mem() calls it like this: static int mmap_mem(struct file * file, struct vm_area_struct * vma) { size_t size = vma->vm_end - vma->vm_start; if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size)) So that's not much help either. This patch makes the hook take a pfn instead of a phys address.

2006-07-11[PATCH] powerpc: fix trigger handling in the new irq codeBenjamin Herrenschmidt1-1/+1
This patch slightly reworks the new irq code to fix a small design error. I removed the passing of the trigger to the map() calls entirely, it was not a good idea to have one call do two different things. It also fixes a couple of corner cases. Mapping a linux virtual irq to a physical irq now does only that. Setting the trigger is a different action which has a different call. The main changes are: - I no longer call host->ops->map() for an already mapped irq, I just return the virtual number that was already mapped. It was called before to give an opportunity to change the trigger, but that was causing issues as that could happen while the interrupt was in use by a device, and because of the trigger change, map would potentially muck around with things in a racy way. That was causing much burden on a given's controller implementation of map() to get it right. This is much simpler now. map() is only called on the initial mapping of an irq, meaning that you know that this irq is _not_ being used. You can initialize the hardware if you want (though you don't have to). - Controllers that can handle different type of triggers (level/edge/etc...) now implement the standard irq_chip->set_type() call as defined by the generic code. That means that you can use the standard set_irq_type() to configure an irq line manually if you wish or (though I don't like that interface), pass explicit trigger flags to request_irq() as defined by the generic kernel interfaces. Also, using those interfaces guarantees that your controller set_type callback is called with the descriptor lock held, thus providing locking against activity on the same interrupt (including mask/unmask/etc...) automatically. A result is that, for example, MPIC's own map() implementation calls irq_set_type(NONE) to configure the hardware to the default triggers. - To allow the above, the irq_map array entry for the new mapped interrupt is now set before map() callback is called for the controller. - The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function for mapping interrupts from the device-tree now also call the separate set_irq_type(), and only does so if there is a change in the trigger type. - While I was at it, I changed pci_read_irq_line() (which is the helper I would expect most archs to use in their pcibios_fixup() to get the PCI interrupt routing from the device tree) to also handle a fallback when the DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an interrupt number from the device. That number is then mapped using the default controller, and the trigger is set to level low. That default behaviour works for several platforms that don't have a proper interrupt tree like Pegasos. If it doesn't work for your platform, then either provide a proper interrupt tree from the firmware so that fallback isn't needed, or don't call pci_read_irq_line() - Add back a bit that got dropped by my main rework patch for properly clearing pending IPIs on pSeries when using a kexec Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-06Input: introduce input_inject_event() functionDmitry Torokhov1-18/+18
Create input_inject_event() function which is to be used by input handlers as opposed to input_event() which is reserved for drivers implementing input devices. The difference is that if device is "grabbed" by some process input_inject_event() will ignore events unless sent from the handle that is currently owns the device.

2006-07-06Input: add start() method to input handlersDmitry Torokhov1-19/+20
The new start() method is called immediately after connect() and also when "grabbed" device is released by its owner. This will allow input handlers to re-synchronize state of once-grabbed device with the rest of devices. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-07-04[PATCH] sched: cleanup, remove task_t, convert to struct task_structIngo Molnar1-1/+1
cleanup: remove task_t and convert all the uses to struct task_struct. I introduced it for the scheduler anno and it was a mistake. Conversion was mostly scripted, the result was reviewed and all secondary whitespace and style impact (if any) was fixed up by hand.
