The use of uint64_t primitive type in NFS structures forces the compiler to align data on an 8-byte boundary.
As a result of this, unwanted gaps being created, which causes NFS to fail. (e.g., nfs_read/initialize the request)
Using nfsuint64 instead of uint64_t fixes this issue.
The build gets broken when both the NFS and DEBUG_FS_ERROR configurations enabled. This tiny change fixes the compilation error.
Run file through nxstyle and correct issues.
NOTE: This line:
/* This logic just supports "//" sequences in the path name */
generates the false alarm error:
fs/nfs/nfs_util.c:84:39: error: C++ style comment
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/driver, fs/aio, fs/nfs, crypto/, and boards/.
Please note: The modified file under fs/nfs generates several " Mixed case identifier found" errors. Please ignore these. These cannot be fixed without changes to numerous other files. They also follow a non-standard convention that is used many files: Using lower case structure names in custom SIZEOF_ definitions.
* fs/nfs: Remove all nfs_checkmount call. The check just waste cpu cycle since nobody will set nm_mounted to false, and remove the unused fields(nm_mounted and n_flags) and related flags too
* fs/nfs: Fix the definition not confirm to RFC 1813 and other minor issue(unused, typo, duplication, alignment...)
* fs/nfs: Always represent error with negative number and remove the unused arguments from function
* fs/nfs: Set socket receive timeout with nfs_args->timeo and fix warning:
nfs/nfs.h:59:28: warning: large integer implicitly truncated to unsigned type [-Woverflow]
#define NFS_TIMEO (1 * NFS_HZ) /* Default timeout = 1 second */
^
nfs/nfs_vfsops.c:1857:23: note: in expansion of macro 'NFS_TIMEO'
nprmt.timeo = NFS_TIMEO;
^
^~~~~~~~~
* fs/nfs: Update the file attribute correctly in nfs_filetruncate and simplify the attrbitue conversion between NFSv3 and NuttX
* fs/nfs: Remove the unfinished and buggy EXCLUSIVE creation mode
* fs/nfs: Call nfs_fsinfo in nfs_bind instead of nfs_statfs since we should update the buffer size before transfer happen, and handle the attribute existence variance correctly.
* fs/nfs: Shouldn't insert node into list again in nfs_dup and fix other typo issue
* fs/nfs: Should skip . and .. in nfs_readdir
* fs/nfs: Remove the unnecessary dynamic allocation and the duplicated root handle storage
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
fs/nxffs: Add partial implementation of the truncate method: It extend files, but cannot yet shrink them.
fs/smartfs: Add partial implementation of the truncate method: It extend files, but cannot yet shrink them.
fs/fat: Add partial implementation of the truncate method: It extend files, but no yet shrink them.
fs/nfs: Add support for the truncate method to the NFS file system.
fs: Add truncate() support for userfs
fs/unionfs: Add truncate() support to the unionfs
fs/tmpfs: Add ftruncate() support to tmpfs
syscall/: Add system call support for ftruncate()
net/route: Adding ftruncate() support eliminates an issue in file-based routing table management.
fs: Add basic framework to support truncate() and ftruncate(). The infrastructure is complete. Now, however, the actual implementation of ftruncate() will have to be done for each file system.
This commit backs out most of commit b4747286b1. That change was added because sem_wait() would sometimes cause cancellation points inappropriated. But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.
In the OS, all calls to sem_wait() changed to nxsem_wait(). nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.
In all OS functions (not libraries), change sem_wait() to nxsem_wait(). This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.
sched/semaphore: Add the function nxsem_wait(). This is a new internal OS interface. It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.
sched/semaphore: Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable. Changed all references to sem_post in the OS to nxsem_post().
sched/semaphore: Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable. Changed all references to sem_destroy() in the OS to nxsem_destroy().
libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable. Changed all references to sem_setprotocol in the OS to nxsem_setprotocol(). sem_getprotocol() was not used in the OS
libc/semaphore: Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable. Changed all references to sem_getvalue in the OS to nxsem_getvalue().
sched/semaphore: Rename all internal private functions from sem_xyz to nxsem_xyz. The sem_ prefix is (will be) reserved only for the application semaphore interfaces.
libc/semaphore: Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable. Changed all references to sem_init in the OS to nxsem_init().
sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.
sched/semaphoate: Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
net/: psock_recvfrom() is an internal interface and should not set the errno nor should it be a cancellation point.
net/: psock_accept() is not a cancellation point.
net/: psock_getsockopt() and psock_socket*9 are an internal interfaces and should not set the errno.
net/: psock_getsockopt() is an internal interface and should not set the errno.
net/: psock_listen() is an internal interface and should not set the errno.
net/: psock_connect(( is an internal interface and should not set the errno nor should it be a cancellation point.
net/: psock_bind() is an internal interface and should not set the errno.
net/: psock_accept() is an internal interface and should not set the errno.
