setuid() sets the effective user ID of the calling process. If the
effective UID of the caller is root, the real UID and saved set-user-ID
are also set. On success, zero is returned. On error, -1 is returned,
and errno is set appropriately.
there are cases where setuid() can fail even when the caller is UID 0;
it is a grave security error to omit checking for a failure return from
setuid(). if an environment limits the number of processes a user can
have, setuid() might fail if the target uid already is at the limit.
Fix is to check return value of setuid.

Lazy unmount are only supported on Linux. Force umount instead, since
this code path is used in emergency exit anyway.
On NetBSD, just have the filesystem calling exit, the kernel will unmount.

- Break-way from '/var/lib/glusterd' hard-coded previously,
instead rely on 'configure' value from 'localstatedir'
- Provide 's/lib/db' as default working directory for gluster
management daemon for BSD and Darwin based installations
- loff_t is really off_t on Darwin
- fix-off the warnings generated by clang on FreeBSD/Darwin
- Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all
platforms.
- Define proper environment for running tests, define correct PATH
and LD_LIBRARY_PATH when running tests, so that the desired version
of glusterfs is used, regardless where it is installed.
(Thanks to manu@netbsd.org for this additional work)

The change for Bug 853895 fixed mounting volumes read-only for recent
kernels. Older kernels fail the first mount() syscall, and the second
mount() did not add the 'mountflags'.
Full analysis and a description for reproducing is in the bugreport. The
test included in http://review.gluster.org/4163 would have caught this
problem when the tests are executed on RHEL-5 or similar systems.

The internal mount API had no access to the generic
mountflags used by mount(2).
Thus the "ro" mount option that needs to be passed down to mount(2) as
as a mountflag was incorrectly mangled into the fuse-specific mount
parameter string (cf. http://review.gluster.com/655).
This commit fixes the internal API and the "ro" issue. It also adds a
check for the "rw" and "ro" mount options in tests/basic/mount.t.
Thanks to Csaba Henk (csaba@) for suggestions and proposing an updated
patch.

Commit 7d0397c2 introduced two issues:
i) broke the libfuse derived mount logic (details below)
ii) in case of a daemonized glusterfs client is ran as daemon, parent
process can return earlier than the mount is in place, which breaks
agents that programmatically do a gluster mount via a direct call to
glusterfs (ie. not via mount(8)).
This patch fixes these issues by a refactor that merges the approaches
sported by commits
7d0397c2 fuse: allow requests during mount (needed for SELinux labels)
c5d781e0 upon daemonizing, wait on mtab update to terminate in parent
Original daemonized libfuse event flow is as follows:
try:
fd = open("/dev/fuse")
mount("-oopts,fd=%s" % fd ...)
mount(8) -f # manipulate mtab
except:
sp = socketpair()
env _FUSE_COMMFD=sp fusermount -oopts
fd = receive_fd(sp)
where fusermount(1) does:
fd = open("/dev/fuse")
mount("-oopts,fd=%d" % fd ...)
sp = atoi(getenv("_FUSE_COMMFD"))
send_fd(sp, fd)
daemonize(
# in child
fuse_loop(fd)
)
# in parent
exit()
As of 013850c9 (instead of adopting FUSE's 47e61004¹), we went for async
mtab manipulation, and as of c5d781e0, still wanted keep that in sync
with termination of daemon parent, so we changed it to:
try:
fd = open("/dev/fuse")
mount("-oopts,fd=%s" % fd ...)
pid = fork(
# in child
mount(8) -f
)
except:
sp = socketpair()
env _FUSE_COMMFD=sp fusermount -oopts
fd = receive_fd(sp)
daemonize(
fuse_loop(fd)
)
waitpid(pid)
exit()
(Note the new approch came only to direct [privileged] mount, so fusermount
based mounting was already partially broken.)
As of 7d0397c2, with the purpose of facilitating async mount, the event flow
was practically reduced to:
fd = open("/dev/fuse")
fork(
mount("-oopts,fd=%s" % fd ...)
fork(
mount(8) -n
)
)
daemonize(
fuse_loop(fd)
)
exit()
Thus fusermount based mounting become defunct; however, the dead
code was still kept around. So, we should either drop it or fix
it. Also, the mtab manipulator is forked into yet another child
with no purpose, while syncing with it in daemon parent is broken.
mount(2) is neither synced with parent.
Now we are coming to the following scheme:
fd = open("/dev/fuse")
pid = fork(
try:
mount("-oopts,fd=%s" % fd ...)
mount(8) -n
except:
env _FUSE_DEVFD=fd fusermount -oopts
)
where fusermount(1) does:
fd = getenv("_FUSE_DEVFD")
mount("-oopts,fd=%s" % fd ...)
daemonize(
fuse_loop(fd)
)
waitpid(pid)
exit()
Nb.:
- We can't help losing compatibility with upstream fusermount,
as it sends back the fd only when mount(2) is completed,
thus defeating the async mount approach. The
'getenv("_FUSE_DEVFD")' mechanism is specfic to glusterfs'
fusermount (at the moment -- sure we can talk about it with
upstream)
- fusermount opens /dev/fuse at same privilege level as of
original process², so we can bravely go on with doing the open
unconditionally in original process
- Original mounting code actually tries to mount through
fusermount _twice_: if first attempt fails, then, assuming
subtype support is missing in kernel, it tries again subtype
stripped. However, this is redundant, as fusermount internally
also performs the subtype check³. Therefore we simplified the
logic to have just a single fusermount call.
- we revert the changes to mount.glusterfs as of 7d0397c2, as
now there is no issue with glusterfs to work around in that scope

This fixes the race in between the mtab update attempts of mount and umount
when we do a lazy umount right after mounting, in order to hide the given fs
instance; yet this way we still avoid the deadlock of the fs and mount which
we can hit if we wait unconditionally for the mtab update to terminate (cf.
bz #511).

commit 555d6b504308eac6b976321ce938ee4bec62c354
Author: Miklos Szeredi <mszeredi@suse.cz>
Date: Tue Sep 28 10:13:24 2010 +0200
Fix option escaping for fusermount.
If the "fsname=" option contained a comma then the option parser in
fusermount was confused (Novell bugzilla #641480). Fix by escaping
commas when passing them over to fusermount.

Instead of taking libfuse's approach to the bug referred
-- making use of an ad-hoc mount option --, we get over
the issue by not waiting for mtab manipulation to complete.
If mtab manipulation happens to fail for some reason, just
log an error message (instead of aborting the mount).
