11 years agoV4L/DVB (9492): unplug oops from dvb_frontend_init...
Daniel J Blueman [Mon, 2 Jun 2008 23:05:14 +0000]
V4L/DVB (9492): unplug oops from dvb_frontend_init...

When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with
2.6.24, I was met with an oops [1]. The problem is relevant to
2.6.25/26-rc also.

dvb_frontend_init() was called either from re-creation of the kdvb-fe0
thread - seems unlikely, or someone called
dvb_frontend_reinitialise(), causing this path in the thread - really
unlikely, as I can't find any call-site for it.

Either way, quite a number of drivers call dvb_usb_generic_rw() [2]
without checking the validity of the relevant member in the
dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw()
sanity-check and fail (rather than loading from 0x120) seems
reasonable defensive programming [3], in light of it being called in
this way.

The problem with this, is that drivers don't check the return code of
the init call [4]. Does it make sense to cook a patch which allows the
failure to be propagated back up, or am I missing something else?

Thanks,
  Daniel

sda-line is stuck high and thus does not register the i2c-bus.

cx88-dvb however does not check if the i2c-bus is valid and just
uses core->i2c_adap to attach dvb frontend modules.
This leads to an oops at the first call to i2c_transfer:

Suresh Siddha [Mon, 20 Oct 2008 20:57:02 +0000]
V4L/DVB (9356): [PATCH] saa7134: fix resource map sanity check conflict

Impact: driver could possibly stomp on resources outside of its scope

{mchehab@redhat.com: I got two versions of the same patch (identical,
except for whitespacing). One authored by Andy Burns and another
authored by Suresh Siddha. Due to that, I'm applying the one that has
less CodingStyle errors. I'm also adding both comments and the SOB's for
both patches, since they are both interesting}

Suresh Siddha commented:

  Alexey Fisher reported:

  > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000
  > 0xcfefffff PCI Bus 0000:01

  BAR base is located in the middle of the 4K page and the hardcoded
  size argument makes the request span two pages causing the conflict.

  Fix the hard coded size argument in ioremap().

Andy Burns commented:

  I have already sent this patch on the linux-dvb list, but it didn't get
  much attention, so re-sending direct, I hope you all don't mind.

  While attempting to run mythtv in a xen domU, I encountered problems
  loading the driver for my saa7134 card, with an error from ioremap().

  This error was due to the driver allocating an incorrectly sized mmio
  area, which was trapped by xen's permission checks, but this would go
  un-noticed on a kernel without xen.

  My card has a 1K sized mmio area, I've had information that other cards
  have 2K areas, perhaps others have different sizes, yet the driver
  always attempts to map 4K.  I realise that the granularity of mapping is
  the page size, which typically would be 4K, but unless the card's base
  address happens to fall on a 4K boundary (mine does not) then the
  base+4K will end up spanning two pages, and this is when the error
  occurs under xen.

  My patch uses the pci_resource_len macro to determine the size required
  for the user's particular card, instead of the hardcoded 4K value. I've
  tested with a couple of printk() inside ioremap() that the start address
  and size do get rounded to the closest page boundary.

  With this patch I am able to successfully load the saa7134 driver and
  run mythtv under xen with my card, subject to correct pollirq settings
  in case of shared IRQ, I am still seeing occasional DMA panics, which I
  think are related to swiotlb handling by dom0/domU, usually the panic
  occurs when changing mux, once tuned to a mux, 12 hour continuous
  recordings are possible without errors.

libata: revert convert-to-block-tagging patches

This patch reverts the following three commits which convert libata to
use block layer tagging.

 43a49cbdf31e812c0d8f553d433b09b421f5d52c
 e013e13bf605b9e6b702adffbe2853cfc60e7806
 2fca5ccf97d2c28bcfce44f5b07d85e74e3cd18e

Although using block layer tagging is the right direction, due to the
tight coupling among tag number, data structure allocation and
hardware command slot allocation, libata doesn't work correctly with
the current conversion.

The biggest problem is guaranteeing that tag 0 is always used for
non-NCQ commands.  Due to the way blk-tag is implemented and how SCSI
starts and finishes requests, such guarantee can't be made.  I'm not
sure whether this would actually break any low level driver but it
doesn't look like a good idea to break such assumption given the
frailty of ATA controllers.

So, for the time being, keep using the old dumb in-libata qc
allocation.

Fix nfsd truncation of readdir results

Commit 8d7c4203 "nfsd: fix failure to set eof in readdir in some
situations" introduced a bug: on a directory in an exported ext3
filesystem with dir_index unset, a READDIR will only return about 250
entries, even if the directory was larger.

Bisected it back to this commit; reverting it fixes the problem.

It turns out that in this case ext3 reads a block at a time, then
returns from readdir, which means we can end up with buf.full==0 but
with more entries in the directory still to be read.  Before 8d7c4203
(but after c002a6c797 "Optimise NFS readdir hack slightly"), this would
cause us to return the READDIR result immediately, but with the eof bit
unset.  That could cause a performance regression (because the client
would need more roundtrips to the server to read the whole directory),
but no loss in correctness, since the cleared eof bit caused the client
to send another readdir.  After 8d7c4203, the setting of the eof bit
made this a correctness problem.

So, move nfserr_eof into the loop and remove the buf.full check so that
we loop until buf.used==0.  The following seems to do the right thing
and reduces the network traffic since we don't return a READDIR result
until the buffer is full.

Tested on an empty directory & large directory; eof is properly sent and
there are no more short buffers.

11 years agonet: unix: fix inflight counting bug in garbage collector
Miklos Szeredi [Sun, 9 Nov 2008 14:23:57 +0000]
net: unix: fix inflight counting bug in garbage collector

Previously I assumed that the receive queues of candidates don't
change during the GC.  This is only half true, nothing can be received
from the queues (see comment in unix_gc()), but buffers could be added
through the other half of the socket pair, which may still have file
descriptors referring to it.

This can result in inc_inflight_move_tail() erronously increasing the
"inflight" counter for a unix socket for which dec_inflight() wasn't
previously called.  This in turn can trigger the "BUG_ON(total_refs <
inflight_refs)" in a later garbage collection run.

Fix this by only manipulating the "inflight" counter for sockets which
are candidates themselves.  Duplicating the file references in
unix_attach_fds() is also needed to prevent a socket becoming a
candidate for GC while the skb that contains it is not yet queued.

11 years agoclarify usage expectations for cnt32_to_63()
Nicolas Pitre [Sun, 9 Nov 2008 05:27:53 +0000]
clarify usage expectations for cnt32_to_63()

Currently, all existing users of cnt32_to_63() are fine since the CPU
architectures where it is used don't do read access reordering, and user
mode preemption is disabled already.  It is nevertheless a good idea to
better elaborate usage requirements wrt preemption, and use an explicit
memory barrier on SMP to avoid different CPUs accessing the counter
value in the wrong order.  On UP a simple compiler barrier is
sufficient.

Fix the __pfn_to_page(pfn) macro so that it doesn't evaluate its

bit in a bitmap and the current bit position is modified on each

sched: improve sched_clock() performance

in scheduler-intense workloads native_read_tsc() overhead accounts for
20% of the system overhead:

 659567 system_call                              41222.9375
 686796 schedule                                 435.7843
 718382 __switch_to                              665.1685
 823875 switch_mm                                4526.7857
 1883122 native_read_tsc                          55385.9412
 9761990 total                                      2.8468

this is large part due to the rdtsc_barrier() that is done before
and after reading the TSC.

But sched_clock() is not a precise clock in the GTOD sense, using such
barriers is completely pointless. So remove the barriers and only use
them in vget_cycles().

This improves lat_ctx performance by about 5%.

turned into a pagetable page, we need to make sure all its mappings
are RO.

If the page had been used for ioremap or vmalloc, it may still have
left over mappings as a result of not having been lazily unmapped.
This change makes sure we explicitly mop them all up before pinning
the page.

Unlike aliases created by kmap, the there can be vmalloc aliases even
for non-high pages, so we must do the flush unconditionally.

11 years agovmap: cope with vm_unmap_aliases before vmalloc_init()
Jeremy Fitzhardinge [Tue, 28 Oct 2008 08:22:34 +0000]
vmap: cope with vm_unmap_aliases before vmalloc_init()

Xen can end up calling vm_unmap_aliases() before vmalloc_init() has
been called.  In this case its safe to make it a simple no-op.

David S. Miller [Thu, 6 Nov 2008 23:45:32 +0000]
net: Fix recursive descent in __scm_destroy().

__scm_destroy() walks the list of file descriptors in the scm_fp_list
pointed to by the scm_cookie argument.

Those, in turn, can close sockets and invoke __scm_destroy() again.

There is nothing which limits how deeply this can occur.

The idea for how to fix this is from Linus.  Basically, we do all of
the fput()s at the top level by collecting all of the scm_fp_list
objects hit by an fput().  Inside of the initial __scm_destroy() we
keep running the list until it is empty.

Fix accidental implicit cast in HR-timer conversion

Fix the hrtimer_add_expires_ns() function.  It should take a 'u64 ns' argument,
but rather takes an 'unsigned long ns' argument - which might only be 32-bits.

On FRV, this results in the kernel locking up because hrtimer_forward() passes
the result of a 64-bit multiplication to this function, for which the compiler
discards the top 32-bits - something that didn't happen when ktime_add_ns() was
called directly.
