The system is a linux from scratch build x86_64 I used these flags for building everything: CFLAGS=" -m64 -mtune=core2 -march=core2 -mfpmath=both -O2 -pipe -fomit-frame-pointer -fstack-protector" CXXFLAGS="${CFLAGS}" MAKEOPTS="{-j3}" also: I have a macbook(not x86_64) that is running rc6 that seems to be fine.(I can double check). attached is .config, dmesg as well. -- Justin P.

The problem with doing a git bisect is these kernels are tar.balls although I do have a fresh pulled tree which might work. if not Ill just start reverting commits from the web interface until she boots properly. (luckily its from rc5 to rc6) At the moment I'm trying to get the grub2 properly configured so I can get more of this message on the screen. and then manually write it down.

(been avoiding that one) I'll have to revert (If I can) the whole thing to see if this machine boot's with rc6.

I must admit, I've been afraid of doing a git bisect for some time now. but after learning to do a bisect, I cant see a better solution to finding a bug(biggest issue I see is having a huge .config).

No, it does do the right thing. Your patch breaks things because not all tracepoints are created through TRACE_EVENT() and will thus not have their profile_enable/disable hooks set. By giving them an ID file, there is no way to distinguish good from bad tracepoints. Expempting ftrace is no solid solution, suppose someone else does a TRACE_EVENT_FORMAT() tracepoint, how would you know you could use it as a profile event source? The id files really must stay conditional. Aside from that, you only add #ifdef fuzz back which with his config is moot, and shouldn't result in anything but a slightly bigger structure to begin with. ^ permalink raw reply [flat|nested] 62+ messages in thread

Could you please double-check the bisection result by doing this: git revert af6af30c0f on the latest kernel and seeing whether that fixes the lockup? Bisections are very efficient and hence very sensitive as well to minimal errors. Just one small mistake near the end of a bisection can blame the wrong commit. So the best way to double-check such 100%-triggerable crashes is to do the revert. I tried the revert and it can be done fine here. [ _If_ that does not fix the bug then to save time you can 'backtrack' the bisection, instead of re-doing it completely. I.e. you have your bisection log, re-check the final steps going backwards. Once you find a discrepancy (i.e. a 'bad' point that is 'good' or the other way around), redo the bisection log commands up to that point and continue it up to the end. ] Ingo ^ permalink raw reply [flat|nested] 62+ messages in thread

Anyways after git bisect had finished I looked manually at the commits that it had generated the one which I had sent in a post previously, and this one: 9424edc2da097c8589fcc24a72552d33e54be161 at the time looking at the commit, I see this to be more of the cause because of it being related to elf as so forth, but as soon as I reverted this on rc6 made no difference.(the previous commit fixes this for me, on a regular tar.ball as well as in git. I think at this point since this system is a fresh from scratch build, I think something might be wrong that I'm doing (all the CFLAGS, and such are in a previous post). At the moment I don't have a problem applying a patch to the kernel for this. especially since I'm the only one that seems to be hitting this, then if more and more reports of this happen then we can go from there.

Mattock > O.k. here something awkward about this issue I was experiencing. at the moment I have two imac's here the descriptions: imac A) the one with the problem OS: built from the clfs book x86_64 multilib with only lib64 built everything with these flags: CFLAGS="-m64 -mtune=core2 -march=core2 -mfpmath=both -O2 -pipe -fomit-frame-pointer -fstack-protection" CXXFLAGS="${CFLAGS}" MAKEOPTS="{-j3}" while compiling everything with gcc version: 4.5.0 20090730 imac B) the one that works OS: clfs(just built a few days ago) x86_64 pure64 bit build (lib with a symlink to lib64) CFLAGS="-m64 -mtune=core2 -march=core2 -O2 -pipe -fomit-frame-pointer" CXXFLAGS="${CFLAGS}" MAKEOPTS="{-j3}" gcc version: 4.4.1 (GCC for Cross-LFS 4.4.1.20090722) The only things I can think of is either I hit something because of gcc, something goes wrong with the libraries, or there something happening with either the option of mfpmath=both or stackprotection.

I put back on that system, and hit the error. I add your patch to 2.6.31-rc6, and the latest git(a few days old). I still am hitting this, but with your patch I'm able to see the beginning of this panic: (Ill write it manually) [ 2.523966] kernel panic - not syncing: No init found. try passing init= option to the kernel [ 2.524394] Pid: 1, comm: swapper Not tainted 2.6.31-rc6 #6 [ 2.524633] Call Trace: [ 2.524875] [<ffffffff813a5b72>] panic+0x75/0x120 [ 2.525119] [<ffffffff8100910f>] init_post+0xef/0xf5 [ 2.525357] [<ffffffff815f6cf0>] kernel_init+0x198/0x1a3 [ 2.525600] [<ffffffff8102410a>] child_rip+0xa/0x20 [ 2.525842] [<ffffffff815f6b58>] ? kernel_init+0x0/0x1a3 [ 2.526084] [>ffffffff810224100>] ? child_rip+0x0/0x20 Seems I only hit this with using gcc 4.5.0 and compiling sysvinit with SELinux support to load the policy at boot. (here's the patch I used http://readlist.com/lists/tycho.nsa.gov/selinux/3/15451.html). Sound's like gcc is doing something(correct me if I'm wrong) because the other systems I have are using the same packages except for and older version of gcc. maybe I should update sysvinit with a better patch to load the policy.

I think this is the top part of the error, because before adding your patch the system would boot a little farther(to fast to read anything)down the line, and I did see something in there about a kernel panic.

The 'call' variable is of type 'struct ftrace_event_call'. What's going on is that the 'struct ftrace_event_call' is of size 168 bytes (sizeof(struct ftrace_event_call)) = 168 = 0xA8. However, in memory the structures are 16-byte aligned. Thus, the stride for walking through the pointers needs to be 176 (0xB0), but instead its 168 causing the oops. I've only seen this issue while using gcc (GCC) 4.5.0 20090916, on a vanilla 2.6.31 kernel. That said, I'm not sure the compiler is doing the wrong thing here. The 'struct ftrace_event_call' contains an embedded 'struct list_head' which is 16 bytes. According to the gcc docs, the aligned attribute, 'specifies a minimum alignment for the variable or structure field, measured in bytes'. Thus, at least according to the docs, gcc can increase the alignment of the 'struct ftrace_event_call', from its original specification of 4, to 16. Even in the case where we are working corectly the structures are 8-byte aligned. Thus, I would reccommend the patch below as a preventive measure. Its the minimal patch I've found to resolve this issue. In general, if we are going to walk data structures embedded in a special elf section, I think the general rules needs to be to set the alignment to the power of two which is greater than or equal to the largest item in the structure. thanks, -Jason Signed-off-by: Jason Baron <jbaron@redhat.com> diff --git a/include/linux/ftrace_event.h b/include/linux/ftrace_event.h index a81170d..7182f03 100644 --- a/include/linux/ftrace_event.h +++ b/include/linux/ftrace_event.h @@ -124,7 +124,10 @@ struct ftrace_event_call { atomic_t profile_count; int (*profile_enable)(struct ftrace_event_call *); void (*profile_disable)(struct ftrace_event_call *); -}; +} __attribute__((aligned(16))); + +/* Align to the largest field in the data structure: + * sizeof(struct list_head) = 16 */ #define MAX_FILTER_PRED 32 #define MAX_FILTER_STR_VAL 128 diff --git a/include/trace/ftrace.h b/include/trace/ftrace.h index f64fbaa..e344e81 100644 --- a/include/trace/ftrace.h +++ b/include/trace/ftrace.h @@ -600,7 +600,6 @@ static int ftrace_raw_init_event_##call(void) \ } \ \ static struct ftrace_event_call __used \ -__attribute__((__aligned__(4))) \ __attribute__((section("_ftrace_events"))) event_##call = { \ .name = #call, \ .system = __stringify(TRACE_SYSTEM), \ ^ permalink raw reply related [flat|nested] 62+ messages in thread

As of now the only thing I can think of besides looking at kernel/compiler is the patch for sysvinit to load the policy(maybe something in there is old/outdated).

From what it looks like init was looking for libselinux in /lib instead of /lib64. after adjusting the Makefile and adding: LDFLAGS = -s -L/lib64 -lselinux -lsepol LIBDIR=/lib64 the system boots right up.

Well, it can be really hard to filter out whether a problem is somehow self-inflicted or caused by the kernel proper - thus we generally prefer over-reporting over under-reporting. Even if it's self-inflicted it's useful on a meta level: if many people report it then we might end up adding more safety guards to disable a particular common pattern of shoot-foot-self incidents.

However, I want to make sure this fix is sufficient and is the best way to address this type of issue in general. For example, I know tracepoints are using the aligned attribute in all 3 places -> definition, usage, and linker alignment. (adding Mathieu to 'cc list). Is just the definition 'aligned' sufficient?

Basically, the vmlinux.lds.h linker script must have alignment statements before each section, which match the alignment of the section structures. Failure to do so would put padding at the beginning of the section, which is definitely not working at all. I don't see how we can automatically pass sizeof(struct list_head) to a linker script :/ Mathieu > > > > #define FTRACE_MAX_PROFILE_SIZE 2048 > > > > diff --git a/include/trace/ftrace.h b/include/trace/ftrace.h > > index cc0d966..31e7637 100644 > > --- a/include/trace/ftrace.h > > +++ b/include/trace/ftrace.h > > @@ -501,7 +501,6 @@ static void ftrace_profile_disable_##call(void) \ > > * } > > * > > * static struct ftrace_event_call __used > > - * __attribute__((__aligned__(4))) > > * __attribute__((section("_ftrace_events"))) event_<call> = { > > * .name = "<call>", > > * .system = "<system>", > > @@ -619,7 +618,6 @@ static int ftrace_raw_init_event_##call(void) \ > > } \ > > \ > > static struct ftrace_event_call __used \ > > -__attribute__((__aligned__(4))) \ > > __attribute__((section("_ftrace_events"))) event_##call = { \ > > .name = #call, \ > > .system = __stringify(TRACE_SYSTEM), \ > > > > > > indeed your patch works as well for me, its much cleaner! > > However, I want to make sure this fix is sufficient and is the best way to > address this type of issue in general.

I'd also add a comment in the C code to tell whoever want to change the size of the structure to also check the linker script. Also adding a BUILD_BUG_ON() that checks the structure sizeof() would be a nice safety-net (this should probably be added to tracepoints too eventually).
