2011-01-20lockdep: Move early boot local IRQ enable/disable status to init/main.cTejun Heo6-36/+15
During early boot, local IRQ is disabled until IRQ subsystem is properly initialized. During this time, no one should enable local IRQ and some operations which usually are not allowed with IRQ disabled, e.g. operations which might sleep or require communications with other processors, are allowed. lockdep tracked this with early_boot_irqs_off/on() callbacks. As other subsystems need this information too, move it to init/main.c and make it generally available. While at it, toggle the boolean to early_boot_irqs_disabled instead of enabled so that it can be initialized with %false and %true indicates the exceptional condition.

2011-01-20virtio: remove virtio-pci root deviceMilton Miller1-18/+2
We sometimes need to map between the virtio device and the given pci device. One such use is OS installer that gets the boot pci device from BIOS and needs to find the relevant block device. Since it can't, installation fails. Instead of creating a top-level devices/virtio-pci directory, create each device under the corresponding pci device node. Symlinks to all virtio-pci devices can be found under the pci driver link in bus/pci/drivers/virtio-pci/devices, and all virtio devices under drivers/bus/virtio/devices.

PROT_EXEC seems to be completely unnecessary (as the lguest binary never executes there), and will allow it to work with SELinux (and more importantly, PaX :-) as they can/do forbid writable and executable mappings. Also, map PROT_NONE guard pages at start and end of guest memory for extra paranoia.

Nothing is printed for the case where HIGH_RES_TIMERS=y. Fix this for the HIGH_RES_TIMERS=y case by duplicating the printk from the low res NOHZ path in the high res NOHZ path.

2011-01-19perf: Fix find_get_context() vs perf_event_exit_task() raceOleg Nesterov1-14/+20
find_get_context() must not install the new perf_event_context if the task has already passed perf_event_exit_task(). If nothing else, this means the memory leak. Initially ctx->refcount == 2, it is supposed that perf_event_exit_task_context() should participate and do the necessary put_ctx(). find_lively_task_by_vpid() checks PF_EXITING but this buys nothing, by the time we call find_get_context() this task can be already dead. To the point, cmpxchg() can succeed when the task has already done the last schedule(). Change find_get_context() to populate task->perf_event_ctxp[] under task->perf_event_mutex, this way we can trust PF_EXITING because perf_event_exit_task() takes the same mutex. Also, change perf_event_exit_task_context() to use rcu_dereference(). Probably this is not strictly needed, but with or without this change find_get_context() can race with setup_new_exec()->perf_event_exit_task(), rcu_dereference() looks better.

2011-01-19cifs: don't fail writepages on -EAGAIN errorsJeff Layton1-12/+37
If CIFSSMBWrite2 returns -EAGAIN, then the error should be considered temporary. CIFS should retry the write instead of setting an error on the mapping and returning. For WB_SYNC_ALL, just retry the write immediately. In the WB_SYNC_NONE case, call redirty_page_for_writeback on all of the pages that didn't get written out and then move on. Also, fix up the handling of a short write with a successful return code. MS-CIFS says that 0 bytes_written means ENOSPC or EFBIG. It doesn't mention what a short, but non-zero write means, so for now treat it as we would an -EAGAIN return.

That commit is wrong for two reasons: - The conn->sec_level shouldn't be updated without performing authentication first (as it's supposed to represent the level of security that the existing connection has) - A higher auth_type value doesn't mean "more secure" like the commit seems to assume. E.g. dedicated bonding with MITM protection is 0x03 whereas general bonding without MITM protection is 0x04. hci_conn_auth already takes care of updating conn->auth_type so hci_connect doesn't need to do it.

The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128). Note that this might also remedy user reports of very sluggish behavior of IR receive with hdpvr hardware. v2: make sure (len <= (dev->i2c_buf)) [Jean Delvare] Reported-by: Jean Delvare <[email protected]> Acked-by: Jean Delvare <[email protected]> Signed-off-by: Jarod Wilson <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
