2006-11-17Input: i8042 - fix shutdown issue on some boxes with active MUXesDmitry Torokhov
MUX error handling has a workaround for KBCs that get confused which port data came from and signal MUXERR while data is actually good. Unfortunately this workaround hurts with KBCs that signal timeouts as 0xfc (spec says that only 0xfd, 0xfe and 0xff are alowed with MUXERR) since it causes endless attempts to rescan i8042 serio ports. The solution is to treat 0xfc as timeout (0xfe). Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-11-17Input: mousedev - remap BTN_FORWARD from BTN_LEFT to BTN_MIDDLEMarton Nemeth
In mousedev the BTN_LEFT and BTN_FORWARD were mapped to mouse button 0, causing that the user space program cannot distinguish between them through /dev/input/mice. All mice have BTN_LEFT, but not all have BTN_MIDDLE (e.g. Clevo D410J laptop). Mapping BTN_FORWARD to mouse button 2 makes the BTN_FORWARD button useful on this laptop.

Mouse button emulation for the one-button mouse Apple machines isn't restricted to older ADB based machines. There are PPC Powerbooks where the keyboard and the mouse are no longer on the ADB bus but regular USB, and users still like (and need) to be able to emulate the middle mouse button with F11 and the right mouse button with F12.

2006-11-17Input: appletouch - verious updates for MacBooksJason Parekh
Change a bit the finger detection method used by the appletouch driver to reduce touchpad "jumpiness": - Adjust the method for detecting multiple fingers. Previously, it recognized a new finger when a low sensor reading is followed by a high sensor reading. The new method checks for 'humps' in the sensor readings, so there doesn't necessarily have to be a low sensor between two high sensors for two fingers to be triggered. This allows detecting presence of two fingers on the touchpad even when they touch each other. - Change absolute coordinate calculation to us to get rid of "jumps". Instead of using full value from a sensor once it passes the threshold subtract theshold value from the reading. - Allow adjusting threshold value via module parameter. The patch doesn't seem to affect the Powerbooks but does greatly improve the touchpad behaviour on the MacBooks.

2006-11-04Input: HID - add a quirk for the Logitech USB ReceiverAnssi Hannula
Logitech USB Receiver (046d:c101) has two interfaces. The first one contains fields from HID_UP_KEYBOARD and HID_UP_LED, and the other one contains fields from HID_UP_CONSUMER and HID_UP_LOGIVENDOR. This device is used with multiple wireless Logitech products, including UltraX Media Remote. All fields on both interfaces are either keys or leds. All fields in the first interface are marked as Absolute, while the fields in the second interface are marked as Relative. Marking the keys as relative causes hidinput_hid_event() to send release events right after key press events. The device has EV_REP set, so the userspace expects the device to send repeat events if a key is held down. However, as hidinput_hid_event() sends release events immediately, repeat events are not sent at all. In fact, the userspace has no way of knowing if a key is being held down. Fix this by adding a quirk for 046d:c101 which changes relative keys to absolute ones. Signed-off-by: Anssi Hannula <anssi.hannula@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-11-04Make sure "user->sigpending" count is in syncLinus Torvalds
The previous commit (45c18b0bb579b5c1b89f8c99f1b6ffa4c586ba08, aka "Fix unlikely (but possible) race condition on task->user access") fixed a potential oops due to __sigqueue_alloc() getting its "user" pointer out of sync with switch_user(), and accessing a user pointer that had been de-allocated on another CPU. It still left another (much less serious) problem, where a concurrent __sigqueue_alloc and swich_user could cause sigqueue_alloc to do signal pending reference counting for a _different_ user than the one it then actually ended up using. No oops, but we'd end up with the wrong signal accounting. Another case of Oleg's eagle-eyes picking up the problem. This is trivially fixed by just making sure we load whichever "user" structure we decide to use (it doesn't matter _which_ one we pick, we just need to pick one) just once.

2006-11-04Fix unlikely (but possible) race condition on task->user accessLinus Torvalds
There's a possible race condition when doing a "switch_uid()" from one user to another, which could race with another thread doing a signal allocation and looking at the old thread ->user pointer as it is freed. This explains an oops reported by Lukasz Trabinski: http://permalink.gmane.org/gmane.linux.kernel/462241 We fix this by delaying the (reference-counted) freeing of the user structure until the thread signal handler lock has been released, so that we know that the signal allocation has either seen the new value or has properly incremented the reference count of the old one. Race identified by Oleg Nesterov.

2006-11-04Revert unintentional "volatile" changes in ipc/msg.cLinus Torvalds
Commit 5a06a363ef48444186f18095ae1b932dddbbfa89 ("[PATCH] ipc/msg.c: clean up coding style") breaks fakeroot on Alpha (variously hangs or oopses), according to a report by Falk Hueffner. The fact that the code seems to rely on compiler access ordering through the use of "volatile" is a pretty certain sign that the code has locking problems, and we should fix those properly and then remove the whole "volatile" entirely. But in the meantime, the movement of "volatile" was unintentional, and should be reverted.

2006-11-03[PATCH] Fix user.* xattr permission check for sticky dirsAndreas Gruenbacher
The user.* extended attributes are only allowed on regular files and directories. Sticky directories further restrict write access to the owner and privileged users. (See the attr(5) man page for an explanation.) The original check in ext2/ext3 when user.* xattrs were merged was more restrictive than intended, and when the xattr permission checks were moved into the VFS, read access to user.* attributes on sticky directores ended up being denied in addition.

2006-11-03[PATCH] Fix sys_move_pages when a NULL node list is passedStephen Rothwell
sys_move_pages() uses vmalloc() to allocate an array of structures that is fills with information passed from user mode and then passes to do_stat_pages() (in the case the node list is NULL). do_stat_pages() depends on a marker in the node field of the structure to decide how large the array is and this marker is correctly inserted into the last element of the array. However, vmalloc() doesn't zero the memory it allocates and if the user passes NULL for the node list, then the node fields are not filled in (except for the end marker). If the memory the vmalloc() returned happend to have a word with the marker value in it in just the right place, do_pages_stat will fail to fill the status field of part of the array and we will return (random) kernel data to user mode.

2006-11-03[PATCH] uml: include tidyingJeff Dike
In order to get the __NR_* constants, we need sys/syscall.h. linux/unistd.h works as well since it includes syscall.h, however syscall.h is more parsimonious. We were inconsistent in this, and this patch adds syscall.h includes where necessary and removes linux/unistd.h includes where they are not needed. asm/unistd.h also includes the __NR_* constants, but these are not the glibc-sanctioned ones, so this also removes one such inclusion.

2006-11-03[PATCH] uml: fix I/O hangJeff Dike
Fix a UML hang in which everything would just stop until some I/O happened - a ping, someone whacking the keyboard - at which point everything would start up again as though nothing had happened. The cause was gcc reordering some code which absolutely needed to be executed in the order in the source. When unblock_signals switches signals from off to on, it needs to see if any interrupts had happened in the critical section. The interrupt handlers check signals_enabled - if it is zero, then the handler adds a bit to the "pending" bitmask and returns. unblock_signals checks this mask to see if any signals need to be delivered. The crucial part is this: signals_enabled = 1; save_pending = pending; if(save_pending == 0) return; pending = 0; In order to avoid an interrupt arriving between reading pending and setting it to zero, in which case, the record of the interrupt would be erased, signals are enabled. What happened was that gcc reordered this so that 'save_pending = pending' came before 'signals_enabled = 1', creating a one-instruction window within which an interrupt could arrive, set its bit in pending, and have it be immediately erased. When the I/O workload is purely disk-based, the loss of a block device interrupt stops the entire I/O system because the next block request will wait for the current one to finish. Thus the system hangs until something else causes some I/O to arrive, such as a network packet or console input. The fix to this particular problem is a memory barrier between enabling signals and reading the pending signal mask. An xchg would also probably work. Looking over this code for similar problems led me to do a few more things: - make signals_enabled and pending volatile so that they don't get cached in registers - add an mb() to the return paths of block_signals and unblock_signals so that the modification of signals_enabled doesn't get shuffled into the caller in the event that these are inlined in the future.

2006-11-03[PATCH] reiserfs: reset errval after initializing bitmap cacheJeff Mahoney
Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL until much later. If a condition fails before errval is reset later, reiserfs_fill_super() will mistakenly return 0, causing an Oops in do_add_mount(). This patch resets errval to -EINVAL after the call. I view this as a temporary fix and real error codes should be used throughout reiserfs_fill_super().

2006-11-03[PATCH] Cleanup read_pages()OGAWA Hirofumi
Current read_pages() assume ->readpages() frees the passed pages. This patch free the pages in ->read_pages(), if those were remaining in the pages_list. So, readpages() just can ignore the remaining pages in pages_list.

2006-11-03[PATCH] fix UFS superblock alignment issuesEric Sandeen
ufs2 fails to mount on x86_64, claiming bad magic. This is because ufs_super_block_third's fs_un1 member is padded out by 4 bytes for 8-byte alignment, pushing down the rest of the struct. Forcing this to be packed solves it. I took a quick look over other on-disk structures and didn't immediately find other problems. I was able to mount & ls a populated ufs2 filesystem w/ this change.

2006-11-03[PATCH] Fix ipc entries removalPavel Emelianov
Fix two issuses related to ipc_ids->entries freeing. 1. When freeing ipc namespace we need to free entries allocated with ipc_init_ids(). 2. When removing old entries in grow_ary() ipc_rcu_putref() may be called on entries set to &ids->nullentry earlier in ipc_init_ids(). This is almost impossible without namespaces, but with them this situation becomes possible. Found during OpenVZ testing after obvious leaks in beancounters.
