some wording related to the *at form... but it needed a general overhaul.
Add some missing errors for the *at form... plus EINVAL for the
traditional form for when you pass a bogus check mode.
Note that the AT_EACCESS flag is useless and strengthen the security
warning.
the TLS pointer, therefore wrecking the pthread environement.
Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha)
that controlled whether setcontext() would change the TLS pointer.
This change let libpthread override setcontext() with its own version
that unsets _UC_TLSBASE, enabling safe usage of setcontext() with
-lpthread.
We also have the following required changes here:
- rename alpha's _UC_UNIQUE into _UC_TLSBASE
- add _UC_TLSBASE definition in header file for all ports
(powerpc, sh3, sparc and sparc64 lack the implementation for now)
- introduce a libc stub that can be overriden for setcontext()
- modify MD libcs swapcontext() implementations so that they use the
setcontext() libc stub instead of doing a plain system call.
While we are there:
- document various MD _UC_* flags in header file
- add libc and libpthread tests for swapcontext() behavior
(hopefully helpful to spot MD problems introduced with this change)
Future work:
- Deciding whether kernel support or _UC_TLSBASE should be added for
powerpc, sh3, sparc and sparc64 is left to portmasters
sparc64

changes required to support these options. The -e option was
requested by martin@ in private chat in order to make writing tests
easier (i.e. don't bother testing MODULAR functionaility if it
doesn't exist). While there, I added -A and -a since those were
quite similar.
-A Tells you whether or not modules can be autoloaded at the moment.
This option does take into consideration the sysctl
kern.module.autoload.
-a Tells you whether or not modules can be autoloaded at the moment.
This option does not take into consideration the sysctl
kern.module.autoload.
-e Tells you whether or not you may load a module at the moment.
assertion failure (and thus a crash in DIAGNOSTIC kernels). Independently
discovered by YAMAMOTO Takashi and Joel Sing.
To avoid this, introduce a cpu_mcontext_validate() function and move all
sanity checks from cpu_setmcontext() there. Also untangle the netbsd32
compat mess slightly and add a cpu_mcontext32_validate() cousin there.
Add an exhaustive atf test case, based partly on code from Joel Sing.
Should finally fix the remaining open part of PR kern/43903.
Adjust various man pages and other documentation to point to capfile(5)
instead of termcap(5).
Remove getcap(3) as curses hasn't been building it for a long time.
Punt wrterm.c as tset no longer uses it.
- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
builds)
