[PATCH] fault injection: process filtering for fault-injection capabilities

This patch provides process filtering feature.
The process filter allows failing only permitted processes
by /proc/<pid>/make-it-fail

Please see the example that demostrates how to inject slab allocation
failures into module init/cleanup code
in Documentation/fault-injection/fault-injection.txt

Akinobu Mita [Fri, 8 Dec 2006 10:39:46 +0000]
[PATCH] fault-injection capability for disk IO

This patch provides fault-injection capability for disk IO.

Boot option:

fail_make_request=<probability>,<interval>,<space>,<times>

<interval> -- specifies the interval of failures.

<probability> -- specifies how often it should fail in percent.

<space> -- specifies the size of free space where disk IO can be issued
   safely in bytes.

<times> -- specifies how many times failures may happen at most.

Debugfs:

/debug/fail_make_request/interval
/debug/fail_make_request/probability
/debug/fail_make_request/specifies
/debug/fail_make_request/times

Example:

fail_make_request=10,100,0,-1
echo 1 > /sys/blocks/hda/hda1/make-it-fail

generic_make_request() on /dev/hda1 fails once per 10 times.

[PATCH] fault injection: documentation and scripts

This patch set provides some fault-injection capabilities.

- kmalloc() failures

- alloc_pages() failures

- disk IO errors

We can see what really happens if those failures happen.

In order to enable these fault-injection capabilities:

1. Enable relevant config options (CONFIG_FAILSLAB, CONFIG_PAGE_ALLOC,
   CONFIG_MAKE_REQUEST) and if you want to configure them via debugfs,
   enable CONFIG_FAULT_INJECTION_DEBUG_FS.

2. Build and boot with this kernel

3. Configure fault-injection capabilities behavior by boot option or debugfs

   - Boot option

     failslab=
     fail_page_alloc=
     fail_make_request=

   - Debugfs

     /debug/failslab/*
     /debug/fail_page_alloc/*
     /debug/fail_make_request/*

   Please refer to the Documentation/fault-injection/fault-injection.txt
   for details.

4. See what really happens.

[PATCH] ISDN: Avoid a potential NULL ptr deref in ippp

There's a potential problem in isdn_ppp.c::isdn_ppp_decompress().
dev_alloc_skb() may fail and return NULL. If it does we will be passing a
NULL skb_out to ipc->decompress() and may also end up
dereferencing a NULL pointer at

    *proto = isdn_ppp_strip_proto(skb_out);

Correct this by testing 'skb_out' against NULL early and bail out.

[PATCH] termios: Enable new style termios ioctls on x86-64

This turns on the split input/output speed features and arbitary baud rate
handling for the x86-64 platform.  Nothing should break if you use existing
standard speeds.  If you use the new speed stuff then you may see some
drivers failing to report the speed changes properly in error cases.  This
will be worked on further.  For the working cases this all seems happy.
I'll post a test suite used to test the basic stuff as well.

Patches for i386 will follow when I get a moment but are basically the
same.  If people could patch/test-suite other architectures and submit them
that would be great.

13 years ago[PATCH] tty_ioctl: use termios for the old structure and termios2 for the new
Alan Cox [Fri, 8 Dec 2006 10:38:47 +0000]
[PATCH] tty_ioctl: use termios for the old structure and termios2 for the new

Having split out the user and kernel structures it turns out that some non
glibc C libraries pull their termios struct from the kernel headers
directly or indirectly.  This means we must keep "struct termios" as the
library sees it correct for the old ioctls.  Not a big problem just shuffle
the names and ifdef around a bit

Alan Cox [Fri, 8 Dec 2006 10:38:45 +0000]
[PATCH] tty: switch to ktermios

This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

Alan Cox [Fri, 8 Dec 2006 10:38:44 +0000]
[PATCH] tty: switch to ktermios and new framework

This is the core of the switch to the new framework.  I've split it from the
driver patches which are mostly search/replace and would encourage people to
give this one a good hard stare.

The references to BOTHER and ISHIFT are the termios values that must be
defined by a platform once it wants to turn on "new style" ioctl support.  The
code patches here ensure that providing

1. The termios overlays the ktermios in memory
2. The only new kernel only fields are c_ispeed/c_ospeed (or none)

the existing behaviour is retained.  This is true for the patches at this
point in time.

Future patches will define BOTHER, ISHIFT and enable newer termios structures
for each architecture, and once they are all done some of the ifdefs also
vanish.

13 years ago[PATCH] tty: preparatory structures for termios revamp
Alan Cox [Fri, 8 Dec 2006 10:38:43 +0000]
[PATCH] tty: preparatory structures for termios revamp

In order to sort out our struct termios and add proper speed control we need
to separate the kernel and user termios structures.  Glibc is fine but the
other libraries rely on the kernel exported struct termios and we need to
extend this without breaking the ABI/API

To do so we add a struct ktermios which is the kernel view of a termios
structure and overlaps the struct termios with extra fields on the end for
now.  (That limitation will go away in later patches).  Some platforms (eg
alpha) planned ahead and thus use the same struct for both, others did not.

This just adds the structures but does not use them, it seems a sensible
splitting point for bisect if there are compile failures (not that I expect
them)
