Tasks
I've unreleased vfile-6.0.0 for jupiter and vfile-7.0.0 for kismet.
The previous unrelease of vfile-6.0.0 that was for kismet is now a jupiter unrelease.
This had to be done because a backward-incompatible change was made to vfile as part of preparations for verification, so jupiter vfile needed to roll from vfile-5.1.2 to vfile-6.0.0.
The backward-incompatible change has to do with the conversion of some macros to functions to aid structural coverage in drivers.
Here's a list of the changes:
| The macro that was... | Is now the API... |
| CREATE_DIR | createDirectory |
| CREATE_PROCFS_GROUP | createProcfsGroup |
| CREATE_PROCFS_FILE_RO | createProcfsFile* |
| CREATE_PROCFS_FILE_WO | createProcfsFile* |
| CREATE_PROCFS_FILE_RW | createProcfsFile* |
| CREATE_SYSFS_GROUP | createSysfsGroup |
| CREATE_SYSFS_ATTR_RO | createSysfsAttribute* |
| CREATE_SYSFS_ATTR_WO | createSysfsAttribute* |
| CREATE_SYSFS_ATTR_RW | createSysfsAttribute* |
| DEFAULT_PROCFS_OPEN | removed, not needed |
| DEFAULT_PROCFS_IOCTL | removed, not needed |
| DEFAULT_PROCFS_CLOSE | removed, not needed |
- The obfuscation of functions provided via the macros is now exposed at the API interface.
Consult the vfile UG for the API signatures.
Driver authors will want to make sure to convert to the APIs as soon as possible for drivers in active development or verification.
Addendum: Drivers that do not use any of the macros listed above will likely work as-is (no migration necessary) with vfile 6.
