13 years agoplip: fix parport_register_device name parameter
Mikulas Patocka [Thu, 22 Nov 2007 20:26:01 +0000 (21:26 +0100)]
plip: fix parport_register_device name parameter

Plip passes a string "name" that is allocated on stack to
parport_register_device.  parport_register_device holds the pointer to
"name" and when the registering function exits, it points nowhere.

On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.

The patch also fixes documentation to note this requirement.

13 years agoplip: use netif_rx_ni() for packet receive
Mikulas Patocka [Thu, 22 Nov 2007 20:19:39 +0000 (21:19 +0100)]
plip: use netif_rx_ni() for packet receive

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd.  For calling from outside interrupts, netif_rx_ni exists.

This fixes plip to use netif_rx_ni.  It fixes the infamous error "NOHZ:
local_softirq_panding 08" that happens on some machines with NOHZ and
plip --- it is caused by the fact that softirq is pending and ksoftirqd

For a kernel built with "make ARCH=x86" the following system

On some i386 systems (e.g. K7) we even have the following information

[MIPS] Handle R4000/R4400 mfc0 from count register.

in the exact moment when it matches the compare register no interrupt will
be generated.

This bug may be triggered if the cp0 count register is being used as
clocksource and the compare interrupt as clockevent.  So a simple
workaround is to avoid using the compare for both facilities on the
affected CPUs.

This is different from the workaround suggested in the old errata documents;
at some opportunity probably the official version should be implemented
and tested.  Another thing to find out is which processor versions
exactly are affected.  I only have errata documents upto R4400 V3.0
available so for the moment the code treats all R4000 and R4400 as broken.

clocksource available; this workaround will cause them to fall back to
another clocksource, worst case the "jiffies" source.

[MIPS] Fix context DSP context / TLS pointer switching bug for new threads.

A new born thread starts execution not in schedule but rather in
ret_from_fork which results in it bypassing the part of the code to
load a new context written in C which are the DSP context and the
userlocal register which Linux uses for the TLS pointer.  Frequently
we were just getting away with this bug for a number of reasons:

 o Real world application scenarios are very unlikely to use clone or fork
   in blocks of DSP code.
 o Linux by default runs the child process right after the fork, so the
   child by luck will find all the right context in the DSP and userlocal
   registers.
 o So far the rdhwr instruction was emulated on all hardware so userlocal
   wasn't getting referenced at all and the emulation wasn't suffering
   from the issue since it gets it's value straight from the thread's
   thread_info.

Fixed by moving the code to load the context from switch_to() to
finish_arch_switch which will be called by newborn and old threads.

libata: bump transfer chunk size if it's odd

None of the drives I have follows what the standard says about
transfer chunk size.  Of the four SATA and six PATA ATAPI devices
tested, four ignore transfer chunk size completely and the ones which
honor it don't behave according to the spec when it's odd.

According to the spec, transfer chunk size can be odd if the amount of
data to transfer equals or is smaller than the chunk size and the
device can indicate the same odd number and transfer the whole thing
at one go with a pad byte appended.  However, in reality, none of the
drives I have does that.  They all indicate and transfer even number
of bytes one byte shorter than the chunk size first; then indicate and
transfer two bytes, which is clearly out of spec.

In addition to unnecessary second PIO data phase, this also creates a
weird problem when combined with SATA controllers which perform PIO
via DMA.  Some of these controllers use actualy number of bytes
received to update DMA pointer so chunks which are sized 4n + 2 makes
DMA pointer off by two bytes.  This causes data corruption and buffer
overruns.

This patch rounds nbytes up to the nearest even number such that ATAPI

us back in the same state as we've been in for years.  For later kernels
