* block: add and use scsi_blk_cmd_ioctlPaolo Bonzini2012-01-251-2/+1
| | | | | | | | | | | | | | | | | commit 577ebb374c78314ac4617242f509e2f5e7156649 upstream. Introduce a wrapper around scsi_cmd_ioctl that takes a block device. The function will then be enhanced to detect partition block devices and, in that case, subject the ioctls to whitelisting.

* ide-disk: Fix request requeuingBorislav Petkov2011-10-161-1/+6
| | | | | | | | | | | | | | | | | | | | | | | commit 2c8fc867602e385fd2abe76da0b6bda8ed907547 upstream. Simon Kirby reported that on his RAID setup with idedisk underneath the box OOMs after a couple of days of runtime. Running with CONFIG_DEBUG_KMEMLEAK pointed to idedisk_prep_fn() which unconditionally allocates an ide_cmd struct. However, ide_requeue_and_plug() can be called more than once per request, either from the request issue or the IRQ handler path and do blk_peek_request() ends up in idedisk_prep_fn() repeatedly, allocating a struct ide_cmd everytime and "forgetting" the previous pointer. Make sure the code reuses the old allocated chunk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disk event code automatically blocks events on excl write. This is primarily to avoid issuing polling commands while burning is in progress. This behavior doesn't fit other types of devices with removeable media where polling commands don't have adverse side effects and door locking usually doesn't exist. This patch introduces new genhd flag which controls the auto-blocking behavior and uses it to enable auto-blocking only on optical devices.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check_events() implementations in both ide-gd and ide-cd are inadequate for in-kernel event polling. Both generate media change events continuously when certain conditions are met causing infinite event loop between the driver and userland event handler. As disk event now supports suppression of unlisted events, simply de-listing DISK_EVENT_MEDIA_CHANGE from disk->events resolves the problem. Internal handling around media revalidation will behave the same while userland will fall back to userland event polling after detecting the device doesn't support disk events.

The conversion is mostly mechanical. The only notable change is that cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT. It used to return -EINVAL which would be treated as media changed. As media changer isn't supported anyway, this doesn't make any difference. This makes ide emit the standard disk events and allows kernel event polling. Currently, only MEDIA_CHANGE event is implemented. Adding support for EJECT_REQUEST shouldn't be difficult; however, given that ide driver is already deprecated, it probably is best to leave it alone.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

* ide: clean up timed out request handlingTejun Heo2010-10-261-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8f6205cd572fece673da0255d74843680f67f879 introduced a bug where a timed out DMA request is never requeued and lost. 6072f7491f5ef391a575e18a1165e72a3eef1601 fixed this by making ide_dma_timeout_retry() requeue the request itself. While the fix is correct, it makes DMA and non-DMA paths asymmetric regarding how the in flight request is requeued. As long as hwif->rq is set, the IDE driver is assuming ownership of the request and the request should either be completed or requeued when clearing hwif->rq. In the timeout path, the ide driver holds onto the request as long as the recovery action (ie. reset) is in progress and clears it after the state machine is stopped (ide_stopped return), so the existing requeueing logic is correct. The bug occurred because ide_dma_timeout_retry() explicitly clears hwif->rq without requeueing it. ide_dma_timeout_retry() is called only by ide_timer_expiry() and returns ide_started only when ide_error() would return it - ie. after reset state machine has started in which case the state machine will eventually end up executing the ide_stopped path in ide_timer_expiry() after reset protocol is complete. So, there is no need to clear hwif->rq from ide_dma_timeout_retry(). ide_timer_expiry() will handle it the same way as PIO timeout path. Kill hwif->rq clearing and requeueing from ide_dma_timeout_retry() and let ide_timer_expiry() deal with it. The end result should remain the same. grepping shows ide_dma_timeout_retry() is the only site which clears hwif->rq without taking care of the request, so there shouldn't be similar fallouts.

Deprecate barrier. All REQ_HARDBARRIERs are failed with -EOPNOTSUPP and blk_queue_ordered() is replaced with simpler blk_queue_flush(). blk_queue_flush() takes combinations of REQ_FLUSH and FUA. If a device has write cache and can flush it, it should set REQ_FLUSH. If the device can handle FUA writes, it should also set REQ_FUA. All blk_queue_ordered() users are converted. * ORDERED_DRAIN is mapped to 0 which is the default value. * ORDERED_DRAIN_FLUSH is mapped to REQ_FLUSH. * ORDERED_DRAIN_FLUSH_FUA is mapped to REQ_FLUSH | REQ_FUA.

The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...
