2286fe7635 Second attempt at eliminating .text relocations in shared libraries
compiled with stack protector.

Use libssp_nonshared library to pull __stack_chk_fail_local symbol into
each library that needs it instead of pulling it from libc. GCC
generates local calls to this function which result in absolute
relocations put into position-independent code segment, making dynamic
loader do extra work every time given shared library is being relocated
and making affected text pages non-shareable.

20e76cb365 Add strndup(3) prototype to string.h.
This change was erronously ommitted from the r185690, and attempt
to simply add the prototype to string.h has revealed that several
contributed programs defined local prototypes for strndup(), controlled
by autoconfed config.h. So, manually change #undef HAVE_STRNDUP to
#define HAVE_STRNDUP 1. Next import of the corresponding program would
regenerate config.h, overriding the changes in this commit.

93898f2b2d Widen psaddr_t from uintptr_t to uint64_t. This results in an
ABI change on ILP32 platforms and relating to events.  However
it's harmless on little-endian ILP32 platforms in the sense
that it doesn't cause breakages.  Old ILP32 thread libraries
write a 32-bit th_p and new thread libraries write a 64-bit
th_p.  But due to the fact that we have an unused 32-bit data
field right after th_p and that field is always initialized to
zero, little-endian ILP32 machines effectively have a valid
64-bit th_p by accident. Likewise for new thread libraries and
old libthread_db: little endian ILP32 is unaffected.

At this time we don't support big-endian threaded applications
in GDB, so the breakage for the ILP32 case goes unnoticed.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

53df73db45 - Change how the vmcore target maps FreeBSD thread IDs to GDB ptids. We
now only use the TID and ignore the PID and use pid_to_ptid() to build a
  ptid treating the TID as a PID.  The benefit of this is that the vmcore
  target now uses the same scheme as GDB's remote targets.  As a result,
  the 'tid' command now works for remote targets (however, it only accepts
  TIDs and not addresses of 'struct thread' objects).
- Use gdb_thread_select() to do the actual thread switch for the 'tid' and
  'proc' commands.  This now gives the same UI feedback when switching
  threads as the GDB 'thread' command rather than providing no visual
  output at all.

3461a0f244 Rework how kgdb manages kernel and vmcore files to be a bit more gdb-ish
so that kgdb can be used more like a normal gdb:
- Load the kernel via the standard 'exec' target and allow it to be changed
  via the 'file' command.
  - Instead of explicitly loading the kernel file as the mail symbol file
    during startup, just pass it to gdb_main() as the executable file.
  - Change the kld support (via shared libraries) to cache the address of
    the linker_files and linker_kernel_file variables in addition to the
    offsets of various members in 'struct linker_file'.
  - When a new symbol file is loaded, recompute the addresses and offsets
    used by the kld support code.
  - When a new symbol file is loaded, recalculate the ofs_fix variable to
    account for the different ways a trapframe can be passed to trap
    frame handlers in i386.  This is done by adding a MD
    kgdb_trgt_new_objfile() hook that is empty on all but i386.
  - Don't use the directory name of the kernel specified on the command
    line to find kernel modules in the kld support code.  Instead,
    extract the filename of the current executable via exec_bfd.  Now
    the 'kernel' variable is private to main.c again.
  - Make the 'add-kld' command explicitly fail if no executable is loaded.
- Make the support for vmcores a real core-dump target that opens the
  kernel and vmcore on open and closes the kvm connection when closed, etc.
  - The 'core' command can now be used to select a vmcore to use, either
    a crash dump file or /dev/mem for live debugging.
  - The 'detach' command can be used to detach from a vmcore w/o attaching
    to a new one.
  - kgdb no longer explicitly opens a core dump during startup and no longer
    has to use an atexit() hook to close the kvm connection on shutdown.
  - Symbols for kld's are automatically loaded anytime a core is opened.
    Also, the unread portion of dmesg is dumped just as it was done on kgdb
    startup previously.
- Don't require either a remote target or core dump if a kernel is specified.
  You can now just run 'kgdb kernel' similar to running gdb on an executable
  and later connect to a remote target or core dump.
- Use a more relaxed way to verify remote targets specified via -r.
  Instead of explicitly allowing a few non-file target specifications,
  just assume that if stat() on the arg and on "/dev/" + arg both fail
  that is some non-file target and pass it to gdb.
- Don't use a custom interpreter.  The existing kgdb_init() hook and the
  target_new_objfile() hook give us sufficient hooks during startup to
  setup kgdb-specific behavior now.
- Always add the 'proc', 'tid', and 'add-kld' commands on startup and not
  just if we have a core dump.  Currently the 'proc' and 'tid' commands do
  not work for remote targets (I will fix at least 'tid' in the next round
  of changes though).  However, the 'add-kld' command works fine for
  loading symbols for a kernel module on a remote target.
- Always setup the 'kld' shared library target operations instead of just
  if we have a core dump.  Although symbols for kernel modules are not
  automatically loaded when connecting to a remote target, you can do
  'info sharedlibrary' after connecting to the remote target and kgdb will
  find all the modules.  You can then use the 'sharedlibrary' command to
  load symbols from the module files.
- Change kthr_init() to free the existing list of kthr objects before
  generating a new one.  This allows it to be invoked multiple times
  w/o leaking memory.

  'coreops_suppress_target' variable that GDB provides for suppressing the
  default core dump target.  KGDB will use this new variable so it can
  provide its own core dump target that uses libkvm to work with vmcore
  files.
- Adjust the long name and documentation of the FreeBSD multithreaded core
  dump target so it better matches what GDB's core dump target uses.

36cc36a0ec Change kgdb_parse() to use wrapped versions of parse_expression() and
evaluate_expression() so that any errors are caught and cause the function
to return to 0.  Otherwise the errors posted an exception (via longjmp())
that aborted the current operation.  This fixes the kld handling for
older kernels (6.x and 7.x) that don't have the full pathname stored in
the kernel linker.

d0ca999980 Make again BSD ar(1) the default system ar(1), now properly handling
source upgrades by falling back to GNU ar(1) as necessary.  Option
WITH_BSDAR is gone.  Option _WITH_GNUAR to aid in upgrades is *not*
supposed to be set by the user.

Stop bootstrapping BSD ar(1) on the next __FreeBSD_version bump, as
there are no known bugs in it.  Bump __FreeBSD_version to anticipate
this and to flag the switch to BSD ar(1), should it be needed for
something.

2369087a60 - Rework the kld support to hook into GDB's shared library support.
kgdb(8) now treats kld's as shared libraries relative to the kernel
  "binary".  Thus, you can use 'info sharedlibrary' to list the kld's
  along with 'sharedlibrary' and 'nosharedlibrary' to manage symbol
  loading and unloading.  Note that there isn't an easy way to force GDB
  to use a specific path for a shared library.  However, you can use
  'nosharedlibrary' to unload all the klds and then use 'sharedlibrary'
  to load specific klds where it gets the kld correct and use
  'add-kld' for the kld's where the default open behavior doesn't work.
  klds opened via 'sharedlibrary' (and during startup) do have their
  sections listed in 'info files'.
- Change the 'add-kld' command to use filename completion to complete its
  argument.

d6022a04c5 Don't close the kernel bfd object during startup. Instead, leave it open
and build a section table from the kernel file so that 'info files' output
for kgdb now matches the usage of gdb on a regular file with the exception
that we don't list sections for memory in the crash dump.

5ca09def5b Add support for automatically loading symbols for kld's on startup:
- Add a new 'kgdb_auto_load_klds()' routine which is invoked during
  startup that walks the list of linker files and tries to find a matching
  kld on disk for each non-kernel kld.  If a kld file is found, then it
  is added as if the 'add-kld' command is invoked.  One change from
  'add-kld' is that this method attempts to use the 'pathname' from the
  linker_file structure first to try to load the file.  If that fails
  it then looks in the kernel directory followed by the directories in
  the module path.
- Move the kld file suffix handling into a separate routine so that it
  can be called standalone and to reduce duplicate code in find_kld_path().
- Cache the offsets of members of 'struct linker_file' during startup
  instead of computing them for each 'add-kld'.
- Use GDB's target_read_string() instead of direct KVM access.
- Add all resident sections from a kld by using bfd_map_over_sections() to
  build the section list rather than just adding symbols for ".text",
  ".data", ".bss", and ".rodata".
- Change the 'add-kld' command to do a y/n prompt before adding the
  symbols when run interactively to match 'add-symbol-file'.
