In the case of interval_tree.h only interval_set() uses LASSERT which is removed in this patch and interval_set() instead reports a real error. The header libcfs.h for interval_tree.h is not needed anymore so we can just use the standard linux kernel headers instead.h Signed-off-by:

The 'fld_read_server' uses 'RMF_GENERIC_DATA' to hold the 'FLD_QUERY' RPC reply that is composed of 'struct lu_seq_range_array'. But there is not registered swabber function for 'RMF_GENERIC_DATA'. So the RPC peers need to handle the RPC reply with fixed little-endian format. In theory, we can define new structure with some swabber registered to handle the 'FLD_QUERY' RPC reply result automatically. But from the implementation view, it is not easy to be done within current 'struct req_msg_field' framework. Because the sequence range array in the RPC reply is not fixed length, instead, its length depends on 'lu_seq_range' count, that is unknown when prepare the RPC buffer. Generally, for such flexible length RPC usage, there will be a field in the RPC layout to indicate the data length. But for the 'FLD_READ' RPC, we have no way to do that unless we add new length filed that will broken the on-wire RPC protocol and cause interoperability trouble with old peer. Signed-off-by:

Originally, the logic of handling config_llog_data::cld_refcount is some confusing, it may cause the cld_refcount to be leaked or trigger "LASSERT(atomic_read(&cld->cld_refcount) > 0);" when put the reference. This patch clean related logic as following: 1) When the 'cld' is created, its reference is set as 1. 2) No need additional reference when add the 'cld' into the list 'config_llog_list'. 3) Inrease 'cld_refcount' when set lock data after mgc_enqueue() done successfully by mgc_process_log(). 4) When mgc_requeue_thread() traversals the 'config_llog_list', it needs to take additional reference on each 'cld' to avoid being freed during subsequent processing. The reference also prevents the 'cld' to be dropped from the 'config_llog_list', then the mgc_requeue_thread() can safely locate next 'cld', and then decrease the 'cld_refcount' for previous one. 5) mgc_blocking_ast() will drop the reference of 'cld_refcount' that is taken in mgc_process_log(). 6) The others need to call config_log_find() to find the 'cld' if want to access related config log data. That will increase the 'cld_refcount' to avoid being freed during accessing. The sponsor needs to call config_log_put() after using the 'cld'. 7) Other confused or redundant logic are dropped. On the other hand, the patch also enhances the protection for 'config_llog_data' flags, such as 'cld_stopping'/'cld_lostlock' as following. a) Use 'config_list_lock' (spinlock) to handle the possible parallel accessing of these flags among mgc_requeue_thread() and others config llog data visitors, such as mount/umount, blocking_ast, and so on. b) Use 'config_llog_data::cld_lock' (mutex) to pretect other parallel accessing of these flags among kinds of blockable operations, such as mount, umount, and blocking ast. The 'config_llog_data::cld_lock' is also used for protecting the sub-cld members, such as 'cld_sptlrpc'/'cld_params', and so on. Signed-off-by:

Oleg Drokin authored
By forcing creates to always go via lookup we lose some important caching benefits too. Instead let's trust creates with positive cached entries. Then we have 3 possible outcomes: 1. Negative dentry - we go via atomic_open and do the create by name there. 2. Positive dentry, no contention - we just go straight to ll_intent_file_open and open by fid. 3. positive dentry, contention - by the time we reach the server, the inode is gone. We get ENOENT which is unacceptable to return from create. But since we know it's a create, we substitute it with ESTALE and VFS retries again with LOOKUP_REVAL set, we catch that in revalidate and force a lookup (same path as before this patch).

Current client doesn't check permission before updating filesystem default stripe on MGS, which isn't secure and obvious. Since we setattr on MDS first, and then set default stripe on MGS, we can just return error upon setattr failure. Now filesystem default stripe is stored in ROOT in MDT, so saving it in system config is for compatibility with old servers, this will be removed in the future. Signed-off-by:

This patch resolves IO vs eviction race. After eviction failed export stayed at stale list, a client had IO processing and reconnected during it. A client sent brw rpc with last lock cookie and new connection. The lock with failed export was found and assert was happened. (ost_handler.c:1812:ost_prolong_lock_one()) ASSERTION( lock->l_export == opd->opd_exp ) failed: 1. Skip the lock at ldlm_handle2lock if lock export failed. 2. Validation of lock for IO was added at hpreq_check(). The lock searching is based on granted interval tree. If server doesn`t have a valid lock, it reply to client with ESTALE. Signed-off-by:

The function hai_dump_data_field will do a stack buffer overrun when cat'ing /sys/fs/lustre/.../hsm/actions if an action has some data in it. hai_dump_data_field uses snprintf. But there is no check for truncation, and the value returned by snprintf is used as-is. The coordinator code calls hai_dump_data_field with 12 bytes in the buffer. The 6th byte of data is printed incompletely to make room for the terminating NUL. However snprintf still returns 2, so when hai_dump_data_field writes the final NUL, it does it outside the reserved buffer, in the 13th byte of the buffer. This stack buffer overrun hangs my VM. Fix by checking that there is enough room for the next 2 characters plus the NUL terminator. Don't print half bytes. Change the format to 02X instead of .2X, which makes more sense. Signed-off-by:

Ann Koehler authored
The algorithm for counting freeable objects in the lu_cache shrinker does not scale with the number of cpus. The LU_SS_LRU_LEN counter for each cpu is read and summed at shrink time while holding the lu_sites_guard mutex. With a large number of cpus and low memory conditions, processes bottleneck on the mutex. This mod reduces the time spent counting by using the kernel's percpu counter functions to maintain the length of a site's lru. The summing occurs when a percpu value is incremented or decremented and a threshold is exceeded. lu_cache_shrink_count() simply returns the last such computed sum. This mod also replaces the lu_sites_guard mutex with a rw semaphore. The lock protects the lu_site list, which is modified when a file system is mounted/umounted or when the lu_site is purged. lu_cache_shrink_count simply reads data so it does not need to wait for other readers. lu_cache_shrink_scan, which actually frees the unused objects, is still serialized.

In ll_setattr_raw(), it needs to know if a file is released when the file is being truncated. It used to get this information by accessing lov_stripe_md. This turns out not necessary. This patch removes the access of lov_stripe_md and solves the problem in lov_io_init_released(). Signed-off-by:

Minor clean up, there is no need to assign result to zero, then check if it is less than zero. Just return SUCCESS. Signed-off-by:

The retval status checks in the proceeding do loop return out of function ms_read_attritbute_info if there is an error condition, thus we never reach the end of the loop with retval failed status. Therefore, the retval status check at end of the do loop is redundant and can be removed. Detected with CoverityScan, CID#143000 ("Logically dead code") Signed-off-by:

Having a local variable of 1024 bytes on 64-bit architectures is a bit too much, and I ran into this warning while trying to see what functions use the largest stack: drivers/staging/fbtft/fbtft-sysfs.c: In function 'store_gamma_curve': drivers/staging/fbtft/fbtft-sysfs.c:132:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=] As there is no need for 64-bit gamma values (on 32-bit architectures, we don't use those either), I'm changing the type from 'unsigned long' to 'u32' here, which cuts the required space in half everywhere.

Putting 128 pointers on the stack is rather wasteful, in particular on 64-bit architectures: drivers/staging/rtl8192u/ieee80211/rtl819x_TSProc.c: In function 'RxPktPendingTimeout': drivers/staging/rtl8192u/ieee80211/rtl819x_TSProc.c:92:1: warning: the frame size of 1072 bytes is larger than 1024 bytes [-Wframe-larger-than=] The rtl8192e driver has the exact same function, except that stores the array in its 'ieee' structure. Let's do it the same way here for consistency. Signed-off-by:

This one unfortunately slipped through my own build testing, my patch caused a new build error: bcm2835-camera.c:53:12: error: static declaration of 'bcm2835_v4l2_debug' follows non-static declaration We want the symbol to be global as it is indeed used in more than one file and declared 'extern' in a header. Fixes: 757b9bd0 ("staging: bcm2835: mark all symbols as 'static'") Signed-off-by:

We no longer send payloads back to the s-Par firmware, we can get rid of the initialize and destroy functions since they weren't actually being used just created and destroyed. Signed-off-by:
