The support for ioctls has been added to fuse when using protocol 7.18,
and an equivalent upgrade has been done in fuse lite with commit [ae9aee].
For old kernels, a fall back to protocol 7.8 was implemented, but this
appears not to be supported in not-so-old kernels (e.g. 2.6.35).
With this patch, the fall back protocol is set to 7.12 or to the highest
level supported by the kernel.
This is backporting code from the full FUSE library in order to support
ioctls. The fuse protocol level negociated is now 7.18 instead of 7.8.
A fallback protocol to 7.8 is provided for compatibility with older kernels.
32-bit ioctls are not supported by a 64-bit library
When issuing an utimensat as a consequence of utime(2) or utimensat(2),
fuse had temporarily defined a flag utime_omit_ok to identify whether
the file system supports the values UTIME_OMIT and UTIME_NOW to mean
specific timestamp updatings. The flag has been obsoleted and all
file system are now supposed to comply with the convention.
The OpenSolaris port of libfuse, from which our Solaris-port of
libfuse-lite originated, had to be supplied with some additional
compiler flags in order to compile.
The configure script now detects whether it is running on a Solaris
system. If that is the case it passes the proper compiler flags to
libfuse-lite, so it can compile properly.
Tested on:
- OpenIndiana oi_151a3 / gcc 3.4.3
- OpenIndiana oi_151a7 / gcc 4.3.3
- Solaris 11.1 / gcc 4.5.2
On OpenIndiana, the device names have commas in them. Do not interpret
commas as option separators within the option fsname. As a consequence
this option has to be the last one.
The libfuse used by OpenIndiana has the same features as libfuse-lite
though requiring some code variants. Merging them simplifies supporting
both.
Variants for OpenIndiana are selected when defining __SOLARIS__
