* A feeble attempt at kld compatability. The mount_* programs assume thatpeter1998-11-031-1/+10
| | | | | | | | | | | they cannot mount a filesystem that they cannot see in getvfsbyname(). Part 1 of this is a hack, make vfsisloadable() always return true - the ultimate decider of whether it's loadable or not is kldload() or mount(). Part 2 of this is to have vfsload() call kldload(2) and return success if it works. This means that we will use a viable kld module in preference to an LKM! Ultimately, the thing to do is remove the hacks to do a vfsload in all the mount_* commands and let the kernel do it by itself in mount(2).

* vfork -> fork. The child calls execl() which calls malloc(), sobde1998-10-101-1/+1
| | | | | | | | | vfork() can't be used. We could use alloca() in execl() so that it can be called between vfork() and execve(), but a "portable" popen() shouldn't depend on this. Calling execle() instead of execl() should be fairly safe, since execle() is supposed to be callable from signal handlers and signal handlers can't call malloc(). However, execle() is broken.

* Delete the XXX comments that refer to spinlock recursion. The malloc/free/jb1998-09-301-15/+1
| | | | | | | | | realloc functions check for recursion within the malloc code itself. In a thread-safe library, the single spinlock ensures that no two threads go inside the protected code at the same time. The thread implementation is responsible for ensuring that the spinlock does in fact protect malloc. There was a window of opportunity in which this was not the case. I'll fix that with a commit RSN.

* Back out part of previous commit (even though it's technically correct).alex1998-09-201-1/+17
| | | | | | | | | | | Our spinlock implementation allows a particular thread to obtain a lock multiple times, but release the lock with a single unlock call. Since we're detecting recursion, we know the lock is already owned by the current thread in a previous call and must not be released in the current call. This is really far too dependent on this particular spinlock implementation, so I've added commented out calls to THREAD_UNLOCK in the appropriate places. We can activate this code when spinlock is taught to count each lock operation.

| | | | | | | | | | | In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

| | | | | | | | | - Fix some style errors I made back in 1995. - Add a new flavor of the err(3) family, which takes an explicit errno argument rather than implicitly examining errno. This will make it easier to use these functions in conjunction with modern library interfaces that return an errno value explicitly.
