RT_SIGFRAME_UC(sigframe).uc_sigmask.sig = args->blk_sigset; blk_sigset is u64, but uc_sigmask.sig has type ulong [2], so only a part of mask is restore here. This patch reworks restoring of blocking masks symmetrically to dumping these masks. Signed-off-by:

1 The comment before MAKEFLAGS assignment (see commit 25e8cb5c) talks about -r (and possibly -R) flags and has nothing to do with --no-print-directory. Let's remove the last option to not confuse a reader. 2 The --no-print-directory flag to build and build-crtools shorthands is redundant, because scripts/Makefile.build has it already. Remove.

Update to patch "check: Introduce --ms option" (commit: 379abca9) I find this error in my box: cc -g -O2 -Wall -Werror -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -iquote ../../lib/arch/x86/include -I../../lib session03.c ../../lib/libzdtmtst.a -o session03 session03.c:112:7: error: variably modified ‘stack’ at file scope The reason is : "#define CLONE_STACK_SIZE PAGE_SIZE" is conflict with "#define PAGE_SIZE (sysconf(_SC_PAGESIZE))" defined in <sys/user.h>. I think CLONE_STACK_SIZE should be seted 4096 as session02.c. If this patch is appropriate, please let me know. Signed-off-by:

According to the commit message in the kernel git, a new trap flag JOBCTL_TRAP_INTERRUPT is added, which is set on PTRACE_INTERRUPT and cleared when any trap happens. Currently we have a race window beetwen PTRACE_CONT and PTRACE_INTERRUPT. If a process stops before PTRACE_INTERRUPT, the flag JOBCTL_TRAP_INTERRUPT will be set once again. https://bugzilla.openvz.org/show_bug.cgi?id=2569Signed-off-by:

Page server cannot provide one big pipe with pages. Thus, before this patch, it wrote pages into image in small pieces. Now the page-xfer API accepts pagemaps and pages separately, so we can just use thie API. Signed-off-by: -
