214e9d923e Commit 0c963449d6, 'fs/vfs: Added support for checking if a descriptor is a socket in fstat().', changed sys/stat.h in way that breaks smartfs file-type stat flags. CROMFS is similarly broken, as tools/gencromfs.c was not updated to match the sys/stat.h changes. This commit fixes both issues. It probably is not a good idea to use NuttX sys/stat.h bit-field values directly in stored structure of filesystem. 2018-06-28 07:40:35 -06:00

ae6b80f8b6 fs/fat: Avoid caculating the bogus directory entry address for the FAT root directory (since it has no directory entry). This change should have no effect, other than making the logic clearer. 2018-05-24 06:18:15 -06:00

b3f20f8c5b fs/fat: In fs_stat(), when stat'ing the root directory, avoid calculating the address of the root directory entry. The calculation is bogus (but not harmful) because the root directory does not have a directory entry. Noted by Boris Astardzhiev. 2018-05-23 08:14:22 -06:00

eec44d1f01 This commit adds tools/gencromfs.c, a tool that can be used to generate CROMFS file system images. 
Squashed commit of the following:

    tools/gencromfs.c:  Seems basically functional but has not has not yet been integrated with CROMFS.
    tools/gencromfs.c:  Revist previous commit.  Let's make no assumptions about the compatibility of the host system and NuttX.
    tools/gencromfs.c:  I think access mode bits are sufficiently standard that we can just copy them from the host.  This is don't mostly to pick up the executable bits and other conbinations of bits without doing a bit-for-bit decode.
    tools/gencromfs.c:  Code complete but only partially functional.
    tools/gencromfs.c:  type definitions must precede data definitions
    tools/gencromfs.c:  Adds a little more logic to gencromfs tools.  Still not complete but can traverse directories and generate directory and hard-link nodes.
    tools/gencromfs.c: Beginning of a genromfs tool that will eventually be used for generation of CROMFS file system images.

    sched/sched:  Add new internal OS function nxsched_getparam() that is identical to sched_getparam() except that it does not modify the errno value (actually, the previous value erroneously neglected to set the errno value to begin with, but this fixes both issues).  All usage of sched_getparam() within the OS is replaced with nxsched_getparam().

Squashed commit of the following:

    fs/fat:  Resolves issues with truncating the cluster chain when shrinking files via ftruncate().
    fs/fat:  First cut at implementation file shrinkage logic needed to support ftruncate().  Certainly shrinks the file size but it does not appear to correctly disconnect the cluster chains.
    fs/fat:  Restructure some functions in files to better support forthcoming file shrinkage logic.  Put framework for file shrinkage in place.  That logic is incomplete on initial commit.

7deb24484c This comment converts the underlying IPC used by the UserFS from Unix domain local sockets to UDP LocalHost loopback sockets. The problem with the local sockets is that they do require operations on the top level psuedo-file system inode tree. That tree must be locked during certain traversals such as enumerate mountpoints or enumerating directory entries. 
This conversion is unfortunate in the sense that Unix local domain sockets are relatively lightweight.  LocalHost UDP sockets are much heavier weight since they rely on the full UDP stack.  If anyone is up for a complete redesign, then using some shared memory and a POSIX message queue would be lightweight again.

This commit also fixes several bugs that were not testable before the inode tree deadlock.  I cannot say that the logic is 100% stable but it does not have basic functionality.

Squashed commit of the following:

    fs/userfs:  Order locking so that access to the shared I/O buffer is also locked.

fs/userfs:  This completes coding of the UserFS client and of the UserFS feature in general.  This feature is being merged to main now because I believe it is innocuous.  It is, however, untesed.  The next step will be to develop a test case to verify the feature.
    fs/userfs:  Completes the request logic for the UserFS client.  Still need the logic that receives the responses.
    fs/userfs:  Completes coding for most of the server side of the user filesystem logic.
    fs/userfs:  Big design changes, simplications. Use Unix domain local sockets instead of message queues.  Easier to transfer big data in local sockets than message queues.  Remove character drvier 'factory' it is not necessary.
    fs/userfs:  Minor reparitioning; volume private info does not need to be held on the OS client side.
    libc/userfs:  Add some of the server side logic.
    fs/userfs:  Add some UserFS initialization logic.
    fs/userfs:  Add frame work for the UserFS proxy.  Remove all references to a block driver.  There is no block dricer... what was I thinking?
    fs/userfs: Add some initialization of the character driver, 'factory' device.
    fs/userfs:  Rename from fusefs to userfs to that we don't stomp on someone else's cool name.
    Add a header file describing the fusefs interface.

ea13e24392 Correct a problem that was causing an apparent directory to be reported as a file instead of a directory by opendir. 
This happened after adding these three new procfs entries:

  fs/block
  fs/mount
  fs/usage

Of course, there is no directory fs in this case, only three files that have fs/ in their relative pathnames.  The logic was detecting that fs was the name of the enty to report, but it was then declaring that fs was a file (because fs/block is of type file).

This was fixed by adding a check for matching lenghts.  i.e., if strlen(fs) != strlen(fs/block), then report fs as a directory instead of a file.

7cc63f90d9 sched/semaphore: sem_trywait() modifies the errno value and, hence, should not be used within the OS. Use nxsem_trywait() instead. 2017-10-05 07:59:06 -06:00
Gregory Nutt
9568600ab1 Squashed commit of the following: 
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.

44d88abb83 This commit adds support for routing tables in files in a file system. This might be useful for customized, per-unit routing tables. 
There are two issues with it however:

1. Reading from file system on a per packet basis could be slow.  I think it probably should have a small, in-memory cache of most frequently used routes for good problem.

2. Currently the delroute logic is disabled due to a problem with the design.  NuttX does not currently support truncate().  Therefore, it is not possible to delete entries from the routing table file.

In this current implementation, that leaves the last entry intact at the end of the file.  An alternative design might include a tag on each record to indicate if the record is valid or not.  That would work but would add complexity to the other routing table functions.

The existing implementation is available for testing purposes only if CONFIG_EXPERIMENTAL=y.

Squashed commit of the following:

    net/route:  The current delroute design depends on file truncation.  However, NuttX does not currently support truncate.  Alternative, more complex designs are possible but not implemented.  At present the file routing table are otherwise functional but the delroute logic is disabled via CONFIG_EXPERIMENTAL.  Enable it only if you plan to fix it.

    net/route:  Fix some issues with locking routing table files.

    net/route:  Add partial implementation of delroute for the case where the routing table is in a file.

    net/route:  Add support for seeking to positions in the routing table.

    net/route: Add net_addroute_ipv4/6() using a file-based routing table.

    net/route: Add net_foreach_ipv4/4() using a file-based routing table.

    net/route:  Initial build, configuration, and fs utilies to support routing tables in a file.
