We will need futexes to use in PIE code but futex.h uses BUG_ON helper, so to diet inclusions move BUG_ONs code to include/bug.h. Signed-off-by:

In case if CFLAGS is overriden from command line we don't see our headers anymore. So provide mandatory options in ccflags-y variable to fix that. https://bugzilla.openvz.org/show_bug.cgi?id=2521Reported-by:

This facrots out common core members freeing into pstree.c helper. Per-arch freeing helpers are now symmetrical to the allocating ones. This is a merge of two Cyrill's patches. Signed-off-by: -

This is the first release, that actually doesn't require a custom kernel in order to make all the tool features to work. Just take the v3.8 (with proper config) and that's it :) Another coolness about this release is the ARM port. In this case, however, one does require a custom kernel, since the kcmp system call is not wired into the ARM table in the upstream kernel :( What else? Quite a lot, actually: * C/R ability of a LOT of new stuff * Remote syscall execution * Deprecation of --namespace option * Build system rework * Ability to collect gcov info Signed-off-by: -

In case if here is a fast cpu and make is done in parallel we may have the following error | GEN arch/x86/sys-exec-tbl.c | GEN arch/x86/syscalls.S | CC arch/x86/crtools.o | CC arch/x86/cpu.o | CC arch/x86/syscalls.o | LINK arch/x86/syscalls.built-in.o | In file included from include/restorer.h:12:0, | from arch/x86/crtools.c:19: | include/lock.h: In function ‘futex_set_and_wake’: | include/lock.h:56:2: error: implicit declaration of function ‘sys_futex’ [-Werror=implicit-function-declaration] | cc1: all warnings being treated as errors | make[1]: *** [arch/x86/crtools.o] Error 1 | make: *** [arch/x86] Error 2 This is because crtools.c includes syscall.h but this header is generated by a special script. So use $(deps-after) feature provided by our make engine making sure the header is generated before the deps are started to build. Reported-by:

Since we generate some headers the deps creation may need to be ordered, thus add deps-after variable for this case. Signed-off-by:

Some of ours headers (such as syscall.h) are clashes with system headers names. So we need to be sure that the headers we include as | #include "something.h" being searched in known place. In particular on some machines it it already produced problems. This btw revealved a problem in cr-dump.c -- we've had #include <parasite.h> there. Fix it. Signed-off-by:

This is a bit tricky since the build infrastructure we're switching to is targeted to per-directory targets if simplified Makefiles are used. So I did the following - move rules to compile general sources to Makefile.crtools - main Makefiles now simply calls for scritps/Makefile.build help to generate built-in.o target Also note that we clean up suffixes for implicit rules with .SUFFIXES: this is done on purpose to eliminate any possible side effect in future -- all rules _must_ be described explicitly. Because of implicit rules used in zdtm building procedure I can't use of stict makefile mode and add MAKEFLAGS := -r to the top of the general Makefile. This should be done one day latter (if ever).

Because we need util-net.c for both PIE code and a regular code, just move it to pie/ directory and build with -fpie option, this way we can reuse compiled file in main program without additional compilation pass. Signed-off-by:

At moment built-in .SUFFIXES variable is not cleaned which slows down the building procedure. Add a dummy rule thus the make won't try to lookup rules for scripts/Makefile.version (this happens when last resort rule is used). Note that this is rather a stub for future convenience which doesn't affect much current build procedure. Signed-off-by:

No need to walk up the directories if we need to include protobuf file. This was always a bad use of ability to walk the filesystem from other headers. Same time we don't need -I$(SRC_DIR)/protobuf/ in general makefile anymore. [xemul: Small fixlet in head Makefile, since patch it out-of-order] Signed-off-by:
