pooka 21913eabe5 Rototill.
Ok, ok, a few more words about it: stop holding puffs_cc as a holy
value and passing it around to almost every possible place (popquiz:
which kernel variable does this remind you of?).  Instead, pass
the natural choice, puffs_usermount, and fetch puffs_cc via
puffs_cc_getcc() only in routines which actually need it.  This
not only simplifies code, but (thanks to the introduction of
puffs_cc_getcc()) enables constructs which weren't previously sanely
possible, say layering as a curious example.

There's still a little to do on this front, but this was the major
fs interface blast.

pooka 6a3d9a187d Remove "puffs_cid" from the puffs interface following l-removal

used now should the same information be desired.

agc 8ff3509ad4 Use pthread_[gs]etspecific to store a pointer to the fuse_context
information, enabled if MULTITHREADED_REFUSE is defined at build
time. This is not enabled by default since libpuffs is not
threadsafe yet.

librefuse is still not threadsafe, but this gets rid of a whole lot of
problems in the meantime.

tls 4147a3c54a Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry.  RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros.  Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default.  Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

pooka 6a3281d2da Calling puffs_exit() in fuse_{exit,unmount}() is wrong, as those
shouldn't release resources.  As a quick hack to prevent double
frees etc, introduce "dead" variable into fuse channel to signal
if the backing puffs resource was already freed.  XXX: the check
is only in exit/unmount currently.

Proper fix really depends on some puffs features I still haven't
gotten around to doing.

christos 19468d62cc More fixes:
- make sure that the args array is NULL terminated.
- make sure argc is initialized and argv is set to NULL after freeing.
- make the deep copy function an opt interface function.

xtraeme b18c74c93e Add the $NetBSD$ tag, it's easier to know what revision you have. 2007-05-16 22:17:52 +00:00
christos c0df99a133 - Always check strdup return. For now we are lazy and bail instead of cleaning
up.
- Use malloc and free instead of macros, delete macros.
- Merge the two copies of deep copy and free args that were slightly buggy
  into one and use that one.

XXX: Lots of ints should be size_t.
XXX: Bailing on error is not a good thing for a library.
XXX: Defs.h should be eliminated completely. Not all files need all the headers.

agc 9ceda06dfa The FUSE_USE_VERSION is the definition which the user sets, and which
determines the API.

Provide a default for FUSE_USE_VERSION if it's not set, and use this
value to determine the number of arguments given to fuse_main().

agc dcd3457a33 When parsing arguments for the directory to mount, search backwards from
the end of the argument vector for an argument that doesn't begin with '-',
and use it - this improves upon the previous naive approach of using the
last argument, which could have been placed there by one of the argument
appending functions.

Be consistent with the mount name processing, and always do the
puffs:refuse:filesystem substitution once and once only.
