Currently the following sequence causes a endless loop when extending an IMFS file: - Create a file with zero length and close it. - Make sure nearly no allocatable memory is left. - Open the file and write enough data into it that more than the remaining memory will be used. In that case when extending the IMFS file, the file currently need zero blocks. If allocating enough new blocks fails, the already allocated new blocks will be freed again. The comparison of block>=old_blocks that has been used prior to this patch compared two unsigned numbers. If old_blocks was zero, the comparison of these two numbers always evaluated to true. This patch frees the last block in a separate step to avoid this problem. Fixes #4638
This directory contains for the "file system" library. All supported file systems live under this tree. Currently the supported file systems in this library are: - IMFS or In Memory File System This is the only root file system on RTEMS at the moment. It supports files, directories, device nodes and mount points. It can also be configured to be the miniIMFS. - TFTP and FTP filesystem are part of the libnetworking library. - DEVFS or Device File system - DOSFS, a FAT 12/16/32 MSDOS compatible file system. - NFS Client, can mount NFS exported file systems. - PIPE, a pipe file system. - RFS, The RTEMS File System. --Chris Johns and Joel Sherrill 17 Feb 2010
