Right now the only flag is used to indicate if a ksiginfo_t is a
result of a trap. Add a predicate macro to test for this flag.
* Add initialization macros for ksiginfo_t's.
* Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was
not the result of a trap. This matches the sigcontext trapcode semantics.
* In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal.
Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles
the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by
Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.
repository by christos was part 1). netipsec should now be back as it
was on 2003-09-11, with some very minor changes:
1) Some residual platform-dependent code was moved from ipsec.h to
ipsec_osdep.h; without this, IPSEC_ASSERT() was multiply defined. ipsec.h
now includes ipsec_osdep.h
2) itojun's renaming of netipsec/files.ipsec to netipsec/files.netipsec has
been left in place (it's arguable which name is less confusing but the
rename is pretty harmless).
3) Some #endif TOKEN has been replaced by #endif /* TOKEN */; #endif TOKEN
is invalid and GCC 3 won't compile it.
An i386 kernel with "options FAST_IPSEC" and "options OPENCRYPTO" now
gets through "make depend" but fails to build with errors in ip_input.c.
But it's better than it was (thank heaven for small favors).
When probing a nonexistent slave, we may timeout waiting for an interrupt.
In __wdccommand_start(), for polled data in commands, abort quickly if
status still read 0 after 400ns (for a nonexistant slave, the
command will either be aborted, or the status register will report 0; for
a real device we should have BSY, DRQ or ERR).
Thanks to Alexander Yurchenko for reporting the problem and testing the
fix.
