- I noticed that an NFS connection is automatically dropped.
- Actually, this happens in TCP mode if no traffic happens
for 600 seconds.
- I confirmed that the NFS client on Ubuntu automatically
reconnects to the NFS server when an RPC call failed.
- This commit adds the same behavior to fix the issue.
Impact:
- NFS client in TCP mode

Enabled overriding of LFS_ASSERT/TRACE/DEBUG/etc
This is useful for testing the new erroring assert behavior in CI.
Asserts do not error by default, so this macro needs to be overriden.
It is possible to test this behavior using the existing option of
overriding lfs_util.h with a custom file, by using a small sed
one-line script. But this is much simpler.
This does raise the question if more of the configuration options in
lfs_util.h should be opened up for function-like macro overrides.

This commit broke nxffs. This leaves the first block as empty which
then exposes another bug where when the pack is called because we
have reached the end of flash and need to look for deleted inodes
we search the first block find no inode and assume that there
are no more inodes. This then results in corrupting the filesystem
by writing over existing inodes.
This can be seen by runing the sim:nxffs configuration.
Prior to this commit the first pass of writing files would look like

int epoll_create1(int flags);
...
epoll_create1()
If flags is 0, then, other than the fact that the obsolete
size argument is dropped, epoll_create1() is the same as
epoll_create(). The following value can be included in flags
to obtain different behavior:
EPOLL_CLOEXEC
Set the close-on-exec (FD_CLOEXEC) flag on the new file
descriptor. See the description of the O_CLOEXEC flag in
open(2) for reasons why this may be useful.

This will resolve numerous problems with the way that hard links, in particular "." and ".." are handled. Instead of trying to fudge the stat flags, the correct implementation is to follow the hard link to the final link target node. That is what must determine the attributes of the directory entry.
This PR corrects an error in the ROMFS file system. The error occurred after following a hard link (depending on how the ROMFS image is organized). The error occurred because some of the information buffered before following the links was stale and, hence, out of sync after following the hard link. This would cause random errors when paths containing hardlinks were used with ROMFS.
This PR resolves Issue #1543. Please compare the following output with the output in Issue #1543 to see how the problem was resolved:

Bugfix in fat_createalias: space is now also converted to underbar.
Change (bugfix) in fat_getlfname: init characters (0xff) and '\0' are rewound as well.

Make.dep file should be updated by .config changed after first make.
There are 2 cases affected for this problem:
1) Add source files by config symbol
2) Include header files in #ifdef directive
These 2 cases may not be included in Make.dep and this may prevent the
differential build from working correctly.
If a existing file is opened with overwriting mode e.g. fopen(file, "w+"),
the file size will be incorrect after writing any data to the file.
This bug is caused by previous commit 10903b5, and its changes should be
limited to only O_APPEND mode.
since the current implementation is really a symoblic link not hard link

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.
Block and MTD drivers may be opened and managed as though they were character drivers. But this is really sleight of hand; there is a hidden character driver proxy that mediates the interface to the block and MTD drivers in this case.
fstat(), however, did not account for this. It would report the characteristics of the proxy character driver, not of the underlying block or MTD driver.
This change corrects that. fstat now checks if the character driver is such a proxy and, if so, reports the characteristics of the underlying block or MTD driver, not the proxy character driver.
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
Functions within the OS must never set the errno value. fs_fdopen() was setting the errno value. Now, after some parameter changes, it reports errors via a negated errno integer return value as do most all other internal OS functions.
All complaints fixed except for those that were not possible to fix:
- Used of Mixed case identifier in ESP32 files. These are references to Expressif ROM functions which are outside of the scope of NuttX.
Since littlefs is in active development, it's not a good idea to use its
source code files directly. So upgrade littlefs v2.2.1 by using the littlefs
tar.gz release package instead.
