If realpath() is called on pathnames like "/dev/null/." or "/dev/null/..",
it should fail with [ENOTDIR]. Pathnames like "/dev/null/" already failed as
they should.
Also, put the check for non-directories after lstatting the previous

slashes) is detected, saving an lstat() call and some lines of code.

for these extentions. ctf conversions are really only relevant when
used in coordination with the rest of the bsd*.mk system anyway.
Leave them in place for the normal, non-posix enviornment since
they are quite useful there.
issues with vendors that needed 7.x support have been resolved. Many
vendors are still using 8.x build platforms, however, so bumping this
up to 9.0 will have to wait until that is resolved. Actual support for
building from 8.x still relies on those vendors fixing bugs that are
present as most developers have moved onto 9.x or newer platforms.

way. This allows a clang bootstrap to happen, even when WITHOUT_CLANG
is defined. This is a minimal version of a more extensive change which
can be MFC'd more easily. However, we have to also test to see if
we're building clang as not cc, since the bootstrap for that needs
these cross tools and it is easier to build them in just one place.

this is due to a wrong dereference of a vnode when it's not locked and
can be (potentially) recycled. 'sdvp' cannot be locked on zfs_rename()
entry point because the VFS can't be sure that this scenario is
LOR-free (it might violate the parent->child lock acquisition rule).
Dereference 'tdvp' instead, which is already locked on entry, and access
'sdvp' fields only when it's safe, i.e. under ZFS_ENTER scope.
While at it, remove the usage of VOP_REALVP, as long as this is a NOP
on FreeBSD.

the PowerPC port with all the Open Firmware bits removed and replaced by
their EFI counterparts. On the whole, I think I prefer Open Firmware.
This code is supposed to be an immutable shim that sits on the EFI system
partition, loads /boot/loader.efi from UFS and tells the real loader what
disk/partition to look at. It finds the UFS root partition by the somewhat
braindead approach of picking the first UFS partition it can find. Better
approaches are called for, but this works for now. This shim loader will
also be useful for secure boot in the future, which will require some
rearchitecture.

change in the future. All the consumers were migrated to SBT_MAX and
every new consumer (if any) should from now use this interface.

As per POSIX, the -exec ... {} + primary always returns true, but a non-zero
exit status causes find to return a non-zero exit status itself. GNU does
the same, and also for -execdir ... {} +.
It does not make much sense to return false from the primary only when the
child process happens to be run.
The behaviour for -exec/-execdir ... ; remains unchanged: the primary
returns true or false depending on the exit status, and find's exit status
is unaffected.

Use soreadable()/sowriteable() in socket upcalls to avoid extra wakeups
until we have enough data to read or space to write.
Increase partial receive len from 1K to 128K to not wake up on every

first calls mmap() with the arguments PROT_NONE and MAP_ANON to reserve a
single, contiguous range of virtual addresses for the entire shared library.
Later, rtld calls mmap() with the the shared library's file descriptor
and the argument MAP_FIXED to place the text and data sections within the
reserved range. The rationale for mapping shared libraries in this way is
explained in the commit message for Revision 190885. However, this approach
does have an unintended, negative consequence. Since the first call to
mmap() specifies MAP_ANON and not the shared library's file descriptor, the
kernel has no idea what alignment the vm object backing the file prefers.
As a result, the reserved range's alignment is unlikely to be the same as
the vm object's, and so mapping with superpages becomes impossible. To
address this problem, this revision adds the argument MAP_ALIGNED_SUPER to
the first call to mmap() if the text section is larger than the smallest
superpage size.
To determine if the text section is larger than the smallest superpage
size, rtld must always fetch the page size information. As a result, the
private code for fetching the base page size in rtld's builtin malloc is
redundant. Eliminate it. Requested by: kib
