4684 5539 d 17 h svoboda /trunk/ Even more warnings.  
4593 5573 d 23 h decky /trunk/uspace/srv/vfs/ avoid unaligned memory access  
4587 5574 d 17 h jermar /trunk/uspace/ Implement stat() and VFS_IN_STAT.
Modify bdsh() to use stat() during ls.
In devfs, allow lookups that don't
specify one of L_FILE and L_DIRECTORY.
 
4585 5574 d 20 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.
 
4584 5575 d 1 h jermar /trunk/uspace/ Separate the VFS input and output protocols.  
4566 5577 d 17 h jermar /trunk/uspace/srv/vfs/ Do not use the "pending" fibril mechanism in VFS  
4555 5585 d 16 h jermar /trunk/uspace/srv/vfs/ Finish converting VFS to fibril synchronization.  
4551 5585 d 18 h jermar /trunk/uspace/srv/vfs/ Handle each VFS request using a dedicated connection.  
4539 5587 d 20 h jermar /trunk/uspace/srv/vfs/ Handle pending mounts using only one fibril.  
4520 5592 d 20 h jermar /trunk/uspace/srv/vfs/ Synchronize access to pending_req.  
4518 5593 d 16 h jermar /trunk/uspace/srv/vfs/ Make VFS use the new synchronization for fibrils. Now there should be no (or
only secondary) fibril serialization. Code reorganized not to hold the phone
lock during async_wait_for() in most cases. Tested on ia32. On amd64, VFS
crashes, but I think it is an unrelated problem.
 
4509 5595 d 1 h decky /trunk/uspace/ rename libadt -> adt  
4463 5599 d 20 h decky /trunk/uspace/srv/vfs/ VFS rewrite:
- add new VFS methods
- VFS_NODE for getting VFS node for a file descriptor
- VFS_OPEN_NODE for opening an i-node directly
- VFS_DEVICE for getting the underlying device of a file (if any)
- VFS_SYNC for syncing buffers
- L_OPEN flag is set to underlying filesystem in VFS_LOOKUP when opening a file to support initialization (if any)
- VFS_CLOSE is now propagated to underlying filesystem to support cleanup (if any)
 
4445 5601 d 22 h decky /trunk/uspace/srv/vfs/ revert commit 4443 and implement a much finer solution as suggested by Jakub Jermar in commit 4444  
4443 5604 d 21 h decky /trunk/uspace/srv/vfs/ serialization of VFS_OPEN implementation to avoid lockup by concurrent open() operations from multiple tasks  
4437 5606 d 5 h jermar /trunk/uspace/srv/vfs/ Fix function definition.  
4431 5610 d 22 h jermar /trunk/uspace/srv/vfs/ Hold the namespace rwlock during the entire operation of vfs_mount_internal().
Get rid of rootfs futex, which is not needed anymore.
Do not instantiate VFS node for the mounted root if the mount failed.
 
4427 5612 d 19 h jermar /trunk/uspace/srv/vfs/ Fix rename() on a non-root file system.  
4409 5614 d 17 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4368 5625 d 6 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.
 
4366 5625 d 18 h jermar /trunk/uspace/srv/vfs/ Allow rename("a", "aa");  
4305 5645 d 23 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.
 
4302 5646 d 1 h jermar /trunk/uspace/ Make IPC_M_PING part of the VFS_MOUNT protocol again.  
4301 5646 d 2 h jermar /trunk/uspace/srv/vfs/ Return the actual error code instead of EREFUSED.  
4279 5649 d 20 h svoboda /trunk/uspace/ Nuke strncmp().  
4264 5654 d 18 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
4159 5674 d 18 h jermar /trunk/uspace/srv/vfs/ Just for pro forma, initialize the the link before use.  
4010 5692 d 21 h decky /trunk/uspace/srv/vfs/ support for pending (blocking) mounts (waiting for the presence of the filesystem implementation)
the mount point and filesystem type arguments of VFS_MOUNT were swapped, the IPC_M_PING was eliminated
small cleanups
 
3653 5785 d 23 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3488 5836 d 19 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5884 d 19 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().
 
3255 5898 d 5 h jermar /trunk/uspace/ Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system.
 
3215 5931 d 2 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().
 
3109 5962 d 0 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.
 
3079 5965 d 0 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5980 d 17 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5980 d 19 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.
 
2788 6032 d 7 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.

2770 6048 d 18 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6050 d 19 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.
