Normal logics for altstack handling in sigframe allocation
Signed-off-by: Al Viro
-
usual "call force_sigsegv or signal_delivered" logics. Takes
ksignal instead of separate siginfo/k_sigaction.Signed-off-by: Al Viro
-
On success get_signal_to_deliver() fills k_sigaction and siginfo.
_All_ users pass it addresses of the local variables sitting in
the same function. Then they proceed to pass those addresses
pretty much in tandem to a bunch of helper functions; again, all
callers of those helpers are passing them such a pair, and one that
had been through get_signal_to_deliver() at that.The obvious cleanup: introduce a new type that would contain a
pair (struct ksignal) and begin switching to
using it. Turns out that it's convenient to store the signal number
in the same object.New helper, taking that sucker is a wrapper for get_signal_to_deliver();
takes struct ksignal * and returns bool. On success fills ksignal
with the information for signal handler to be invoked.For now it's a macro (to avoid header ordering headache), but eventually
it'll be a function in kernel/signal.c, with get_signal_to_deliver()
folded into it.Signed-off-by: Al Viro

Only alpha and sparc are unusual - they have ka_restorer in it.

... and make it unconditional - we want the sucker on all biarch
platforms, really. All kinds of wrappers and private implementations
can go now; fortunately, they don't cause name conflicts, so we can

* pull compat version alongside with the native one
* make little-endian compat variant just call the native

compat are going to become unconditional very soon).Signed-off-by: Al Viro

Switch from __ARCH_WANT_SYS_RT_SIGACTION to opposite
(!CONFIG_ODD_RT_SIGACTION); the only two architectures that
need it are alpha and sparc. The reason for use of CONFIG_...
instead of __ARCH_... is that it's needed only kernel-side
and doing it that way avoids a mess with include order on many
architectures.Signed-off-by: Al Viro

The ia64 function "thread_matches()" has no users since commit
e868a55c2a8c ("[IA64] remove find_thread_for_addr()"). Remove it.This allows us to make ptrace_check_attach() static to kernel/ptrace.c,
which is good since we'll need to change the semantics of it and fix up
all the callers.Signed-off-by: Oleg Nesterov

The tty is NULL when the port is hanging up.
chase_port() needs to check for this.This patch is intended for stable series.
The behavior was observed and tested in Linux 3.2 and 3.7.1.Johan Hovold submitted a more elaborate patch for the mainline kernel.
