When comparing usb vs ps2 / testing the keycodes generated for the easy access keys on my trust (microsoft compatible) keyboard. I noticed the search key generated the keycode for find when connected through USB. This lead me to check the consumer page mappings in hid-input.c . And it turns out the the mapping for ID 0x221 deviates from the HUT standard document: http://www.usb.org/developers/devclass_docs/Hut1_12.pdf Currently it is incorrectly mapped to find, whereas it should be mapped to search. I also added missing bindings for ID 0x21f, the real find and for 0x222, goto. Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Microsoft SideWinder GameVoice driver is a trivial device with a few buttons (0x09 HID usage) and an audio connector, which just forwards the audio input into oridinary sound card present in the computer. Despite this fact, the only interface of this device reports itself as a Telephony/Headset type of HID device. This is apparently incorrect - the device itself doesn't provide any audio/telephony functionality. This is achieved in userland application which only needs to receive the button events from the HID driver. This patch establishes a new quirk which forces hid-input to claim a device it will otherwise leave untouched.

Linus Torvalds authored
Commit 1c710c89 added the utimensat() system call, but didn't handle the case of checking for the writability of the target right, when the target was a file descriptor, not a filename. We cannot use vfs_permission(MAY_WRITE) for that case, and need to simply check whether the file descriptor is writable. The oops from using the wrong function was noticed and narrowed down by Markus Trippelsdorf.

PIO4 is a maximum PIO mode supported by a driver. Using "255" as a max_mode argument to ide_get_best_pio_mode() could result in wrong timings being used by a driver (for "pio" equal to 5) or OOPS (for "pio" values > 5 && < 255).

The SiS966 has one additional PCI-ID 1180. If the chipset is using this PCI-ID, the primary channel is connected to the first PATA-port. The secondary channel is connected to SATA-ports in IDE emulation mode. The legacy IO-ports are used. The including of the PCI-ID into pata_sis is not sufficient, because the legacy driver in drivers/ide is initialized before pata_sis.

When cleaning up HIDP sessions, we currently close the ACL connection before deregistering the input device. Closing the ACL connection schedules a workqueue to remove the associated objects from sysfs, but the input device still refers to them -- and if the workqueue happens to run before the input device removal, the kernel will oops when trying to look up PHYSDEVPATH for the removed input device. Fix this by deregistering the input device before closing the connections.

In 7d12e780 David Howells performed this evolution: "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers" He correctly updated many of the function definitions that were using this extra regs pointer parameter but forgot to update some caller sites of those functions. The reason the modifications was not properly done on all drivers is that some drivers were rarely compiled because they are for AMIGA, or that some code sites were inside #ifdefs where the option is not set or inside #if 0.

When we enable the SMCf010 IR device, the Toshiba Portege 4000 BIOS claims the device is working, but it really isn't configured correctly. The BIOS *will* configure it, but only if we call _SRS after (1) reversing the order of the SIR and FIR I/O port regions and (2) changing the IRQ from active-high to active-low. This patch addresses the 2.6.22 regression: "no irda0 interface (2.6.21 was OK), smsc does not find chip" I tested this on a Portege 4000. The smsc-ircc2 driver correctly detects the device, and "irattach irda0 -s && irdadump" shows transmitted and received packets.

A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of files all of which are using the same #ifdef guard, "__ASM_STUB_" with no postfix. So the second and later asm files #included in the same C file (often through standard headers like ioctl.h) yields no symbols. Strangeness with the Ubuntu 'tell me if I support something that's not explcitly mentioned in POSIX, and I'll strip it out' shell, I believe.

Processors synchronization in set_mtrr requires the .gate field to be set after .count field is properly initialized. Without an explicit barrier, the compiler was reordering those memory stores. That was sometimes causing a processor (in ipi_handler) to see the .gate change and decrement .count before the latter is set by set_mtrr() (which then hangs in a infinite loop with irqs disabled).

The commit 635cf99a introduced a regression. Executing a ptrace single step after certain int80 accesses will infinitely loop and never advance the PC. The TIF_SINGLESTEP check should be done on the return from the syscall and not before it. I loops on each single step on the pop right after the int80 which writes out to the console. At that point you can issue as many single steps as you want and it will not advance any further. The test case is below: /* Test whether singlestep through an int80 syscall works. */ #define _GNU_SOURCE #include <stdio.h> #include <unistd.h> #include <fcntl.h> #include <sys/ptrace.h> #include <sys/wait.h> #include <sys/mman.h> #include <asm/user.h> #include <string.h> static int child, status; static struct user_regs_struct regs; static void do_child() { char str[80] = "child: int80 test\n"; ptrace(PTRACE_TRACEME, 0, 0, 0); kill(getpid(), SIGUSR1); write(fileno(stdout),str,strlen(str)); asm ("int $0x80" : : "a" (20)); /* getpid */ } static void do_parent() { unsigned long eip, expected = 0; again: waitpid(child, &status, 0); if (WIFEXITED(status) || WIFSIGNALED(status)) return; if (WIFSTOPPED(status)) { ptrace(PTRACE_GETREGS, child, 0, ®s); eip = regs.eip; if (expected) fprintf(stderr, "child stop @ %08lx, expected %08lx %s\n", eip, expected, eip == expected ?

elf_core_dump() supports dumping arch specific ELF notes, via the #define ELF_CORE_WRITE_EXTRA_NOTES. Currently the only user of this is the powerpc spu coredump code. There is a bug in the handling of foffset WRT the arch notes, which causes us to erroneously increment foffset by the size of the arch notes, leaving a block of zeroes in the file, and causing all subsequent data in the file to be at <supposed position> + <arch note size>. eg: LOAD 0x050000 0x00100000 0x00000000 0x20000 0x20000 R E 0x10000 Tells us we should have a chunk of data at 0x50000. The truth is the data is at 0x90dbc = 0x50000 + 0x40dbc (the size of the arch notes). This bug prevents gdb from reading the core file correctly. The simplest fix is to simply remember the size of the arch notes, and add it to foffset after we've written the arch notes. The only drawback is that if the arch code doesn't write as many bytes as it said it would, we end up with a broken core dump again. For now I think that's a reasonable requirement. Tested on a Cell blade, gdb no longer complains about the core file being bogus. While I'm here I should point out that the spu coredump code does not work if we're dumping to a pipe - we'll have to wait for 23 to fix that.

The idle loop goes to sleep using the WAIT instruction if !need_resched(). This has is suffering from from a race condition that if if just after need_resched has returned 0 an interrupt might set TIF_NEED_RESCHED but we've just completed the test so go to sleep anyway. This would be trivial to fix by just disabling interrupts during that sequence as in: local_irq_disable(); if (!need_resched()) __asm__("wait"); local_irq_enable(); but the processor architecture leaves it undefined if a processor calling WAIT with interrupts disabled will ever restart its pipeline and indeed some processors have made use of the freedom provided by the architecture definition. This has been resolved and the Config7.WII bit indicates that the use of WAIT is safe on 24K, 24KE and 34K cores. It also is safe on 74K starting revision 2.1.0 so enable the use of WAIT with interrupts disabled for 74K based on a c0_prid of at least that. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
