| * drm/i915: Handle pagefaults in execbuffer user relocationsChris Wilson2010-11-231-168/+293
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if we hit a pagefault when applying a user relocation for the execbuffer, we bail and return EFAULT to the application. Instead, we need to unwind, drop the dev->struct_mutex, copy all the relocation entries to a vmalloc array (to avoid any potential circular deadlocks when resolving the pagefault), retake the mutex and then apply the relocations. Afterwards, we need to again drop the lock and copy the vmalloc array back to userspace. v2: Incorporate feedback from Daniel Vetter.

| | | | | | | | | | | | | | | | | | | | | | The GATT is a write-only set of registers, reading from them in the manner of i915_gtt_to_phys() is supposed to be undefined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were reading our 64-bit value in I915_READ64 and returning 32 bits of it. The restoration of fence regs at resume then had a zero end value, and the fence had no effect. Version 2: Split register access functions into per-size versions Sharing code between different sizes seemed reasonable when we only needed a single copy, but as 64-bit access requires its own version, it makes sense to just split them out for each size.

Since we still need to access to this functionality this commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch ext4_trim_fs(). It takes fstrim_range structure as an argument. fstrim_range is definec in the include/linux/fs.h and its definition is as follows. struct fstrim_range { __u64 start; __u64 len; __u64 minlen; } start - first Byte to trim len - number of Bytes to trim from start minlen - minimum extent length to trim, free extents shorter than this number of Bytes will be ignored. This will be rounded up to fs block size. After the FITRIM is done, the number of actually discarded Bytes is stored in fstrim_range.len to give the user better insight on how much storage space has been really released for wear-leveling.

However, the generic_check_addressable clause sets ret = 0 (if it passes), which means that a subsequent failure (e.g. a group checksum error) returns 0 even though the mount should fail. This causes vfs_kern_mount in turn to think that the mount succeeded, leading to an oops. A simple fix is to avoid using ret for the generic_check_addressable check, which was last changed in commit 30ca22c70e3ef0a96ff84de69cd7e8561b416cb2. Signed-off-by: Darrick J.

This only worked as long as the page alignment matched the object offset, breaking direct io to non-page aligned offsets. Instead, explicitly specify the page alignment next to the page vector in the ceph_msg struct, and use that instead of the message header (which probably shouldn't be trusted). The alloc_msg callback is responsible for filling in this field properly when it sets up the page vector. Signed-off-by: Sage Weil <sage@newdream.net>

Now we just look at the mapping to determine that. However, some old behavior remains from that transition. First, rdcache_gen == 0 no longer means we have no pages. That can happen at any time (presumably when we carry FILE_CACHE). We should not reset it to zero, and we should not check that it is zero. That means that the only purpose for rdcache_revoking is to resolve races between new issues of FILE_CACHE and an async invalidate. If they are equal, we should invalidate. On success, we decrement rdcache_revoking, so that it is no longer equal to rdcache_gen. Similarly, if we success in doing a sync invalidate, set revoking = gen - 1. (This is a small optimization to avoid doing unnecessary invalidate work and does not affect correctness.) Signed-off-by: Sage Weil <sage@newdream.net>

Otherwise, a random stat result from a non-auth MDS can clobber a meaningful max_size, get the client<->mds cap state out of sync, and make writes hang. Specifically, even if the client re-requests a larger max_size (which it will), the MDS won't respond because as far as it knows we already have a sufficiently large value.

The skip code was also incrementing the expected seq, such that all subsequent messages also appeared old and got skipped, and an eventual timeout on the osd connection. This resulted in some lagging requests and console messages like [233480.882885] ceph: skipping osd22 10.138.138.13:6804 seq 2016, expected 2017 [233480.882919] ceph: skipping osd22 10.138.138.13:6804 seq 2017, expected 2018 [233480.882963] ceph: skipping osd22 10.138.138.13:6804 seq 2018, expected 2019 [233480.883488] ceph: skipping osd22 10.138.138.13:6804 seq 2019, expected 2020 [233485.219558] ceph: skipping osd22 10.138.138.13:6804 seq 2020, expected 2021 [233485.906595] ceph: skipping osd22 10.138.138.13:6804 seq 2021, expected 2022 [233490.379536] ceph: skipping osd22 10.138.138.13:6804 seq 2022, expected 2023 [233495.523260] ceph: skipping osd22 10.138.138.13:6804 seq 2023, expected 2024 [233495.923194] ceph: skipping osd22 10.138.138.13:6804 seq 2024, expected 2025 [233500.534614] ceph: tid 6023602 timed out on osd22, will reset osd Reported-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Sage Weil <sage@newdream.net>

The intent of issue_seq is to distinguish between mds->client messages that (re)create the cap and those that do not, which means we should _only_ be updating that value in the create paths. By updating it in handle_cap_grant, we reset it to zero, which then breaks release. The larger question is what workload/problem made me think it should be updated here...
