For details, please visit the bug entries and follow the links given in
references.
As you can see, there is a Bugzilla entry for each of the listed regressions.
There also is a Bugzilla entry used for tracking the regressions from 2.6.34,
unresolved as well as resolved, at:
http://bugzilla.kernel.org/show_bug.cgi?id=16055
Please let the tracking team know if there are any Bugzilla entries that
should be added to the list in there.
Thanks!

Whether it's also something that we should change in the kernel is unclear, but at least as of now, the rule is that you cannot compile the kernel with gcc-4.5. No idea whether the compiler is just entirely broken, or whether it's just that it triggers something iffy by being overly clever. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=16346 > Subject : 2.6.35-rc3-git8 - include/linux/fdtable.h:88 invoked rcu_dereference_check() without protection! > Submitter : Miles Lane <miles.lane@gmail.com> > Date : 2010-07-04 22:04 (5 days old) > Message-ID : <AANLkTinof0k28rk4rMr66aubxcRL2rFa5ZEArj1lqD3o@mail.gmail.com> > References : http://marc.info/?l=linux-kernel&m=127828107815930&w=2 I'm not entirely sure if these RCU proving things should count as regressions. Sure, the option to enable RCU proving is new, but the things it reports about generally are not new - and they are usually not even bugs in the sense that they necessarily cause any real problems. That particular one is in the single-thread optimizated case for fget_light, ie if (likely((atomic_read(&files->count) == 1))) { file = fcheck_files(files, fd); where I think it should be entirely safe in all ways without any locking.

Al? I assume this is some late fallout from the BKL removal ages ago.. It's the old filldir-vs-mmap crud, but normally it should be impossible to trigger because the inode for a directory should never be mmap'able, so we should never have the same i_mutex lock used for both mmap and for filldir protection. We saw some of that oddity long ago, I wonder if it's lockdep being confused about some inodes. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=16333 > Subject : iwl3945: HARDWARE GONE?? > Submitter : Priit Laes <plaes@plaes.org> > Date : 2010-07-02 16:02 (7 days old) > Message-ID : <1278086575.2889.8.camel@chi> > References : http://marc.info/?l=linux-kernel&m=127808659705983&w=2 This either got fixed, or will be practically impossible to debug.

Frederic? Right. In fact it wasn't a regression. The per task breakpoint reservation design was broken from the beginning and this warning has revealed the problem. This only touched perf, and it did since perf support breakpoints. Fortunately ptrace wasn't concerned by this problem, even not by side effects of this. The fix is invasive as it's a rewrite of a (little) part of the breakpoint reservation. And since the symptom is only a warning and also breakpoints never released from the constraint table (just a counter, no memory leak), the fix is headed for 2.6.36. It is ready in tip:/perf/core: http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=45a73372efe4a63f44aa2e1125d4a777c2fdc8d8 I think this ticket can be safely closed.

Generally not - and we've delayed at least one more complex (cgroups) fix to v2.6.36 because the patch itself was riskier than the warning. Still most of the warning fixes turned out to be simple, so we merged the very-low-risk ones and right now we seem to be on top of them. But in general the default rule is that we delay these fixes to v2.6.36. > Sure, the option to enable RCU proving is new, but the things it reports > about generally are not new - and they are usually not even bugs in the > sense that they necessarily cause any real problems. > > That particular one is in the single-thread optimizated case for fget_light, ie > > if (likely((atomic_read(&files->count) == 1))) { > file = fcheck_files(files, fd); > > where I think it should be entirely safe in all ways without any locking. So > I think it's a false positive too. Yeah, it's a bit like with lockdep (and it's a bit like with compiler warning fixes): we had to punch through a large stack of false positives that accumulated in the past 10 years. ( Because real bugs eventually get fixed, while false positives always just accumulate. So almost by definition we always start with a very assymetric collection of warnings and a large stack of false positives. ) Having said that, it appears we got most of the false positives and are beginning to be in a more representative equilibrium now. If v2.6.35 isnt going to be warning-free then v2.6.36 certainly will be and new warnings will have a much higher likelyhood of being real (and new) bugs (not just accumulated false-positives).

I think it has been there from the beginning. At least it was there before the reiserfs bkl removal in .32. Indeed the readdir <-> unmap/release inversion problem can not happen. But Al said that can happen between write and release. (Although I don't see where write takes the inode mutex). He also highlighted the fact that reiserfs refcounting based on i_count was totally broken. He has a fix the whole in the vfs tree, in the for-next branch on commit 6c2bdaf089a3876226893fab00dd83596c465ad2 "Fix reiserfs_file_release()" No more uses of the i_mutex on release after that, nor i_count, but a private openers refcount and a tailpack mutex per reiserfs inode. ^ permalink raw reply [flat|nested] 14+ messages in thread

My suspicion is that dhcpd uses netlink to dump the info of the available links, and due to some bug gets confused with the new 64-bit statistic netlink attribute being there now. That shouldn't happen, applications should just ignore the attributes which they don't understand.

It could be a dhcpcd bug because of extended size of answer According to strace, dhcpcd tries a recvmsg() call with a 256 bytes buffer to hold answer. Looking at current dhcpcd source, I confirm it cannot realloc its buffer static int get_netlink(int fd, int flags, int (*callback)(struct nlmsghdr *)) { char *buffer = NULL; ssize_t bytes; struct nlmsghdr *nlm; int r = -1; buffer = xzalloc(sizeof(char) * BUFFERLEN); for (;;) { bytes = recv(fd, buffer, BUFFERLEN, flags); if (bytes == -1) { if (errno == EAGAIN) { r = 0; goto eexit; } if (errno == EINTR) continue; goto eexit; } This program needs to fix this. ^ permalink raw reply [flat|nested] 14+ messages in thread

Agreed, I don't there is any reasonable way we could cater to this application bug with some compatability bits. Restricting the link dump to 256 bytes is just too much inflexibility. If NetworkManager can get this right, dhcpd very well can too :-) ^ permalink raw reply [flat|nested] 14+ messages in thread
