would appear that overloading the argument this way is used by SVR4 to `fall
off' the main context (uc_link being NULL) after a function set up using
makecontext() returns.
RLIM_INFINITY like we do. Java uses rlim_max to allocate a data structure
per file descriptor.
what we do is bogus anyway, because:
setrlimit(RLIM_NOFILE, {RLIM_INFINITY, RLIM_INFINITY}}
sets the limit to { maxfiles, maxfiles }
I undestand that this is so that if we change maxfiles via sysctl, processes
can still use the new maximum, but it is probably more appropriate to return
the current value of maxfiles (and maxproc) at every getrlimit call, even
if the current value for either is RLIM_INFINITY.
Anyway, java now works on the the sparc, on the i386 loses on setcontext().
sparc, and unknown for the rest. Also make sure that the string is terminated
properly and the length is returned as the specification calls. Maybe sometime
we can read the prom on the sparc and return the actual model.
* Increase the size of sigset_t to accomodate 128 signals -- adding new
versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
sys_sigpending() and sys_sigsuspend() into separate functions, and call them
from all the emulations rather than hard-coding everything. (Avoids uses
the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.
Note: Only code touched by the i386 port has been modified. Other ports and
emulations need to be updated.
the individual emulated readdirs must check.
Since netbsd and freebsd return EINVAL for the error
and I don't know what the other platforms do, return
EINVAL for them too.
