tftpd(8) is difficult to test in isolation due to its relationship with
inetd. Create a test program that mimics the behavior of tftp(1) and
inetd(8) and verifies tftpd's response in several different scenarios.
These test cases cover all of the basic TFTP protocol, but not the optional
parts.

objects' init functions instead of doing the setup via a constructor
in libc as the init functions may already depend on these handlers
to be in place. This gets us rid of:
- the undefined order in which libc constructors as __guard_setup()
and jemalloc_constructor() are executed WRT __sparc_utrap_setup(),
- the requirement to link libc last so __sparc_utrap_setup() gets
called prior to constructors in other libraries (see r122883).
For static binaries, crt1.o still sets up the user trap handlers.
o Move misplaced prototypes for MD functions in to the MD prototype
section of rtld.h.
o Sprinkle nitems().
Most notable, other than some style issues:
CVS 1.11:
do not use LOG_CONS.
CVS 1.13:
consistently use exit instead of return in main().
use LOG_WARNING instead of LOG_ERR for non critical errors.

Mainly focus on files that use BSD 2-Clause license, however the tool I

The Software Package Data Exchange (SPDX) group provides a specification

opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,

The old value was probably fine back in 1998, when that code was imported
(although the comments still mention VAX, which was quite obsolete by then);
now, however, it's too small to handle our libc, which results in some
additional calls to munmap/mmap later on. Asking for more virtual address
space is virtually free, and syscalls are not, thus the change.
It was suggested by kib@ that this might be a symptom of a deeper problem.
It doesn't only affect libc, though - the change also improves rtld memory
management for eg KDE libraries. I guess it's just a natural bloat.

The directives I added in r323466 and r323501 did not define a valid
CFA until several instructions into the associated functions. This
triggers an assertion in GDB when generating a stack trace while
stopped at the first instruction of PLT stub entry point since there
is no valid CFA rule for the first instruction.
This is probably just wrong on my part as the non-simple .cfi_startproc
would have defined a valid CFA. Instead, define a valid CFA as sp + 0
at the start of the functions and then use .cfa_def_offset to change the
offset when sp is adjusted later in the function.

This is only cosmetic, but the entry point for rtld is not a leaf function,

Apply authenticated user context after update of wtmp(5) at start of session,
so that ftpd process is not killed by kernel with SIGXFSZ when user has
"filesize" limit lower than size of system wtmp file. Same applies
to session finalization: revert to super-user context before update of wtmp.
If ftpd hits limit while writing a file at user request,
do not get killed with SIGXFSZ instantly but apparently ignore the signal,
process error and report it to the user, and continue with the session.

If they are still needed, you can find them in the net/bsdrcmds port.
This was proposed June, 20th and approved by various committers [1].
They have been marked as deprecated on CURRENT in r320644 [2] on July, 4th.
Both stable/11 and release/11.1 contain the deprecation notice (thanks to
allanjude@).
Note that ruptime(1)/rwho(1)/rwhod(8) were initially thought to be part of
rcmds but this was a mistake and those are therefore NOT removed.

Newer binutils supports extensions to the MIPS ABI for non-PIC code
that is used when compiling O32 binaries with clang 5 (but not used
for N64 oddly enough). These extensions require support for
R_MIPS_COPY relocations as well as a second PLT GOT using
R_MIPS_JUMP_SLOT relocations.
For R_MIPS_COPY, use the same approach as on other architectures where
fixups are deferred to the MD do_copy_relocations.
The additional PLT GOT for jump slots is located in a .got.plt section
which is identified by a DT_MIPS_PLTGOT dynamic entry. This GOT also
requires fixups for the first two GOT entries just as the normal GOT.
However, the entry point for this second GOT uses a different calling
convention. Rather than passing an offset into the GOT, it passes an
offset into the .rel.plt section. This requires a second entry point
(_rtld_pltbind_start) which calls the normal _rtld_bind() rather than
_mips_rtld_bind(). This also means providing a real version of
reloc_jmpslot() which is used by _rtld_bind().
In addition, add real implementions of reloc_plt() and
reloc_jmpslots() which walk .rel.plt handling R_MIPS_JUMP_SLOT
relocations.

In particular, the switch statement on the type of dynamic entries
in _rtld_relocate_nonplt_self() needs to not use a jump table since
jump tables on MIPS use local GOT entries which aren't initialized
until after this loop.

New version is not compatible on supervisor mode with v1.9.1
(previous version).
Highlights:
o BBL (Berkeley Boot Loader) provides no initial page tables
anymore allowing us to choose VM, to build page tables manually
and enable MMU in S-mode.
o SBI interface changed.
o GENERIC kernel.
FDT is now chosen standard for RISC-V hardware description.
DTB is now provided by Spike (golden model simulator). This
allows us to introduce GENERIC kernel. However, description
for console and timer devices is not provided in DTB, so move
these devices temporary to nexus bus.
o Supervisor can't access userspace by default. Solution is to
set SUM (permit Supervisor User Memory access) bit in sstatus
register.
o Compressed extension is now turned on by default.
o External GCC 7.1 compiler used.
o _gp renamed to __global_pointer$
o Compiler -march= string is now in use allowing us to choose
required extensions (compressed, FPU, atomic, etc).

o Replace __riscv64 with (__riscv && __riscv_xlen == 64)

This is compatible with current GCC 6.1 compiler.
RISC-V is extensible ISA and the idea here is to have built-in define

of these as well (depending on -march string passed to compiler):
__riscv_compressed
__riscv_atomic
__riscv_mul
__riscv_div
