This is a note to let you know that I have just added a patch titled um: Fix get_signal() usage to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt2. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From 25cf669207d4627556aceb666a2423636ab10525 Mon Sep 17 00:00:00 2001 From: Richard Weinberger <richard@nod.at> Date: Wed, 18 Nov 2015 09:37:15 +0100 Subject: um: Fix get_signal() usage commit db2f24dc240856fb1d78005307f1523b7b3c121b upstream. If get_signal() returns us a signal to post we must not call it again, otherwise the already posted signal will be overridden. Before commit a610d6e672d this was the case as we stopped the while after a successful handle_signal(). Fixes: a610d6e672d ("pull clearing RESTORE_SIGMASK into block_sigmask()") Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Kamal Mostafa <kamal@canonical.com> --- arch/um/kernel/signal.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 1.9.1
