Thanks Mikael.
Anonymity has some good attributes.
Blame avoidance is one of them.
I've broad shoulders. It's me, then Dwight Howard...
There might be another few of these where ->name or ->dev
was used before struct device or net_device was registered.
I'll go back and check.
tulip_core has:
if (tp->flags & HAS_MEDIA_TABLE) {
sprintf(dev->name, DRV_NAME "%d", board_idx); /* hack */
tulip_parse_eeprom(dev);
strcpy(dev->name, "eth%d"); /* un-hack */
}
So I don't feel _too_ bad.
tulip_parse_eeprom is done before register_netdev so the logging
there can not use netdev_<level> or dev_<level>(&dev->dev

While investigating a bug, I came across a possible bug in v9fs. The
problem is similar to the one reported for NFS by ASANO Masahiro in
http://lkml.org/lkml/2005/12/21/334.
v9fs_file_lock() will skip locks on file which has mode set to 02666.
This is a problem in cases where the mode of the file is changed after
a process has obtained a lock on the file. Such a lock will be skipped
during unlock and the machine will end up with a BUG in
locks_remove_flock().
v9fs_file_lock() should skip the check for mandatory locks when

x86, k8 nb: Fix boot crash: enable k8_northbridges unconditionally on AMD systems
de957628ce7c84764ff41331111036b3ae5bad0f changed setting of the
x86_init.iommu.iommu_init function ptr only when GART IOMMU is
found.
One side effect of it is that num_k8_northbridges
is not initialized anymore if not explicitly
called. This resulted in uninitialized pointers in
<arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>,
for example, which uses the num_k8_northbridges thing through
node_to_k8_nb_misc().
Fix that through an initcall that runs right after the PCI
subsystem and does all the scanning. Then, remove initialization
in gart_iommu_init() which is a rootfs_initcall and we're
running before that.
What is more, since num_k8_northbridges is being used in other
places beside GART IOMMU, include it whenever we add AMD CPU
support. The previous dependency chain in kconfig contained
K8_NB depends on AGP_AMD64|GART_IOMMU
which was clearly incorrect. The more natural way in terms of
hardware dependency should be
AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD &&
PCI. Make it so Number One!

tracing: Do not record user stack trace from NMI context
A bug was found with Li Zefan's ftrace_stress_test that caused applications
to segfault during the test.
Placing a tracing_off() in the segfault code, and examining several
traces, I found that the following was always the case. The lock tracer
was enabled (lockdep being required) and userstack was enabled. Testing
this out, I just enabled the two, but that was not good enough. I needed
to run something else that could trigger it. Running a load like hackbench
did not work, but executing a new program would. The following would
trigger the segfault within seconds:
# echo 1 > /debug/tracing/options/userstacktrace
# echo 1 > /debug/tracing/events/lock/enable
# while :; do ls > /dev/null ; done
Enabling the function graph tracer and looking at what was happening
I finally noticed that all cashes happened just after an NMI.
1) | copy_user_handle_tail() {
1) | bad_area_nosemaphore() {
1) | __bad_area_nosemaphore() {
1) | no_context() {
1) | fixup_exception() {
1) 0.319 us | search_exception_tables();
1) 0.873 us | }
[...]
1) 0.314 us | __rcu_read_unlock();
1) 0.325 us | native_apic_mem_write();
1) 0.943 us | }
1) 0.304 us | rcu_nmi_exit();
[...]
1) 0.479 us | find_vma();
1) | bad_area() {
1) | __bad_area() {
After capturing several traces of failures, all of them happened
after an NMI. Curious about this, I added a trace_printk() to the NMI
handler to read the regs->ip to see where the NMI happened. In which I
found out it was here:
ffffffff8135b660 <page_fault>:
ffffffff8135b660: 48 83 ec 78 sub $0x78,%rsp
ffffffff8135b664: e8 97 01 00 00 callq
ffffffff8135b800 <error_entry>
What was happening is that the NMI would happen at the place that a page
fault occurred. It would call rcu_read_lock() which was traced by
the lock events, and the user_stack_trace would run. This would trigger
a page fault inside the NMI. I do not see where the CR2 register is
saved or restored in NMI handling. This means that it would corrupt
the page fault handling that the NMI interrupted.
The reason the while loop of ls helped trigger the bug, was that
each execution of ls would cause lots of pages to be faulted in, and
increase the chances of the race happening.
The simple solution is to not allow user stack traces in NMI context.
After this patch, I ran the above "ls" test for a couple of hours
without any issues. Without this patch, the bug would trigger in less
than a minute.

tracing: Disable buffer switching when starting or stopping trace
When the trace iterator is read, tracing_start() and tracing_stop()
is called to stop tracing while the iterator is processing the trace
output.
These functions disable both the standard buffer and the max latency
buffer. But if the wakeup tracer is running, it can switch these
buffers between the two disables:
buffer = global_trace.buffer;
if (buffer)
ring_buffer_record_disable(buffer);
<<<--------- swap happens here
buffer = max_tr.buffer;
if (buffer)
ring_buffer_record_disable(buffer);
What happens is that we disabled the same buffer twice. On tracing_start()
we can enable the same buffer twice. All ring_buffer_record_disable()
must be matched with a ring_buffer_record_enable() or the buffer
can be disable permanently, or enable prematurely, and cause a bug
where a reset happens while a trace is commiting.
This patch protects these two by taking the ftrace_max_lock to prevent
a switch from occurring.

tracing: Use same local variable when resetting the ring buffer
In the ftrace code that resets the ring buffer it references the
buffer with a local variable, but then uses the tr->buffer as the
parameter to reset. If the wakeup tracer is running, which can
switch the tr->buffer with the max saved buffer, this can break
the requirement of disabling the buffer before the reset.
buffer = tr->buffer;
ring_buffer_record_disable(buffer);
synchronize_sched();
__tracing_reset(tr->buffer, cpu);
If the tr->buffer is swapped, then the reset is not happening to the

The problem with this is that now the inotify inode is not a distinct inode

to use the inotify inode but may not have had permission to do read/write type
operations on the anon_inode. After looking at the anon_inode and its users

decompress: fix new decompressor for PIC
The ARM kernel decompressor wants to be able to relocate r/w data
independently from the rest of the image, and we do this by ensuring that
r/w data has global visibility. Define STATIC_RW_DATA to be empty to
achieve this.

drivers/char/mmtimer.c: eliminate useless code
The variable x is initialized twice to the same (side effect-free)

The next x = rb_entry(mn->next, struct mmtimer, list); is preceded by a

dma-mapping: sparc: unify 32bit and 64bit dma_set_mask
This patchset transforms the PCI DMA API into the generic device model.
It's one of the reasons why we introduced the generic DMA API long ago;
driver writers are always able to use the generic DMA API with any bus
instead of using bus specific DMA APIs such as pci_map_single,
sbus_map_single, etc (only two bus specific APIs exist now; pci and ssb).
Some of the PCI DMA API are already implented on the top of the generic
DMA API (include/asm-generic/pci-dma-compat.h). But there are some
exceptions. This patchset finishes the transformation.
This patch:
sparc has two dma_set_mask implementations for 32bit and 64bit. They are
same except for the error returned value. We can safely unify them since
the error returned value doesn't matter as long as it is negative (as
DMA-API.txt describes).
This patch also changes dma_set_mask not to call
pci_set_dma_mask. Instead, dma_set_mask does the same thing that
pci_set_dma_mask does. This change enables ut to change
pci_set_dma_mask to call dma_set_mask; we can implement
pci_set_dma_mask as pci-dma-compat.h does.
