[git pull] signals, the first series
From: Al Viro
Date: Tue May 22 2012 - 00:35:24 EST
This is just the first part of the queue (about a half of it);
assorted fixes all over the place in signals' handling. This one ends
with all sigsuspend() implementations switched to generic one
(->saved_sigmask-based), a bunch of assorted old buglets fixed and most
of the missing bits of NOTIFY_RESUME hookup in place (two more sit in
arm and um trees resp. and there's a couple of broken ones that need
obvious fixes - parisc and avr32 check TIF_NOTIFY_RESUME only on one of
two codepaths; that'll go in the next series). Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal.git for-linus
Shortlog:
Al Viro (35):
new helper: sigsuspend()
parisc: resetting ->restart_block.fn needs to be done on rt_sigreturn()
c6x: ->restart_block.fn needs to be reset on rt_sigreturn
hexagon: ->restart_block.fn needs to be reset on rt_sigreturn
microblaze: ->restart_block.fn needs to be reset on rt_sigreturn
score: ->restart_block.fn needs to be reset on rt_sigreturn
xtensa: ->restart_block.fn needs to be reset on rt_sigreturn
avr32: ->restart_block.fn needs to be reset on rt_sigreturn
xtensa: switch to generic rt_sigsuspend(2)
sh: switch to saved_sigmask-based sigsuspend()/rt_sigsuspend()
h8300: don't change blocked signals' mask if setting frame up fails
h8300: switch to saved_sigmask-based sigsuspend/rt_sigsuspend
cris: SA_ONESHOT handling is done by get_signal_to_deliver()
microblaze: bury sys_rt_sigsuspend_wrapper in nommu case too
avr32: need to clear RESTORE_SIGMASK on successful signal delivery
blackfin: don't open-code force_sigsegv()
cris: don't open-code force_sigsegv()
score: don't open-code force_sigsegv()
alpha: tidy signal delivery up
xtensa: xtensa_sigaction doesn't exist
m32r: struct old_sigaction is never used
avr32: struct old_sigaction is never used
sparc: missing checks of __get_user()/__put_user() return values
sh: missing checks of __get_user()/__put_user() return values
powerpc: missing checks of __get_user()/__put_user() return values
cris: missing checks of __get_user()/__put_user() return values
frv: missing checks of __get_user()/__put_user() return values
h8300: missing checks of __get_user()/__put_user() return values
sparc: kill ancient comment in sparc_sigaction()
m68k: add TIF_NOTIFY_RESUME and handle it.
score: add handling of NOTIFY_RESUME to do_notify_resume()
microblaze: handle TIF_NOTIFY_RESUME
microblaze: drop 'oldset' argument of do_notify_resume()
xtensa: add handling of TIF_NOTIFY_RESUME
unicore32: if there's no handler we need to restore sigmask, syscall or no syscall
Matt Fleming (18):
parisc: use set_current_blocked() and block_sigmask()
frv: use set_current_blocked() and block_sigmask()
blackfin: use set_current_blocked() and block_sigmask()
unicore32: use block_sigmask()
h8300: use set_current_blocked() and block_sigmask()
score: don't mask signals if we fail to setup signal stack
score: use set_current_blocked() and block_sigmask()
microblaze: don't reimplement force_sigsegv()
microblaze: no need to reset handler if SA_ONESHOT
microblaze: fix signal masking
microblaze: use set_current_blocked() and block_sigmask()
ia64: use set_current_blocked() and block_sigmask()
cris: use set_current_blocked() and block_sigmask()
mn10300: use set_current_blocked() and block_sigmask()
m32r: use set_current_blocked() and block_sigmask()
avr32: don't mask signals in the error path
avr32: use block_sigmask()
m68k: use set_current_blocked() and block_sigmask()
Oleg Nesterov (2):
avr32: use set_current_blocked() in handle_signal/sys_rt_sigreturn
hexagon: do_notify_resume() needs tracehook_notify_resume()
