The lli_trunc_sem is taken in 'read' mode in both ll_page_mkwrite and vvp_io_fault_start. This can lead to a deadlock with another thread which asks for the semaphore in write mode between thse two read calls. Since all users of lli_trunc_sem are in the vvp layer, we can satisfy the requirement to exclude truncate by taking the semaphore only in vvp_io_fault_start. Signed-off-by:

The reverse order of request_out_callback() and reply_in_callback() puts the RPC into UNREGISTERING state, which is waiting for RPC & bulk md unlink, whereas only RPC md unlink has been called so far. If bulk is lost, even expired_set does not check for UNREGISTERING state. The same for write if server returns an error. This phase is ambiguous, split to UNREG_RPC and UNREG_BULK. Signed-off-by:

Vitaly Fertman authored
A race between unregister_reply & early reply. When buffers are busy for the early transfer, they cannon be unlinked by unregister_reply, so the RPC gets into UNREGISTERING state. The coming reply_in_callback for the early RPC already has unlinked flag set due to previous mdunlink attempt, but we handle it properly only for UNILNK event, whereas this is PUT in this case.

Liang Zhen authored
This patch changes a few things: - There is no guarantee that request_out_callback will happen before reply_in_callback, if a request got reply and unlinked reply buffer before request_out_callback is called, then the thread waiting on ptlrpc_request_set will miss wakeup event. This may seriously impact performance of some IO workloads or result in RPC timeout - To make code more easier to understand, this patch changes action-bits "rq_req_unlink" and "rq_reply_unlink" to status-bits "rq_req_unlinked" and "rq_reply_unlinked" Signed-off-by:

There has been several Lustre Client crashes reported by sites running with Lustre versions 2.1/2.5, all showing the same dentry->d_hash->next corrupted pointer cause. This patch fixes a regression that has been introduced since a long time by commit : (LU-506 kernel: FC15 - support dcache scalability changes.) where i_lock protection usage has been removed and that is likely to cause racy condition during dentry [un]hashing and to be the root cause of these crashes.

Since the inflight request holds import refcount as well as export, sometimes obd_disconnect() in client_common_put_super() can't put the last refcount of OSC import (e.g. due to network disconnection), this will cause cl_cache being accessed after free. To fix this issue, ccc_users is used as cl_cache refcount, and lov/llite/osc all hold one cl_cache refcount respectively, to avoid the race that a new OST is being added into the system when the client is mounted. The following cl_cache functions are added: - cl_cache_init(): allocate and initialize cl_cache - cl_cache_incref(): increase cl_cache refcount - cl_cache_decref(): decrease cl_cache refcount and free the cache if refcount=0.

This patch fixes a non-booting issue in Mainline. When booting with a compressed kernel, we need to be careful how we populate memory close to DDR start. AUTO_ZRELADDR is enabled by default in multi-arch enabled configurations, which place some restrictions on where the kernel is placed and where it will be uncompressed to on boot. AUTO_ZRELADDR takes the decompressor code's start address and masks out the bottom 28 bits to obtain an address to uncompress the kernel to (thus a load address of 0x42000000 means that the kernel will be uncompressed to 0x40000000 i.e. DDR START on this platform). Even changing the load address to after the co-processor's shared memory won't render a booting platform, since the AUTO_ZRELADDR algorithm still ensures the kernel is uncompressed into memory shared with the first co-processor (0x40000000). Another option would be to move loading to 0x4A000000, since this will mean the decompressor will decompress the kernel to 0x48000000. However, this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of memory would essentially be wasted for no good reason. Until we can work with ST to find a suitable memory location to relocate co-processor shared memory, let's disable the shared memory nodes. This will ensure a working platform in the mean time. NB: The more observant of you will notice that we're leaving the DMU shared memory node enabled; this is because a) it is the only one in active use at the time of this writing and b) it is not affected by the current default behaviour which is causing issues.
