Dan Carpenter 5a46e0f956 isdn: type bug in isdn_net_header()
We use len to store the return value from eth_header().  eth_header()
can return -ETH_HLEN (-14).  We want to pass this back instead of
truncating it to 65522 and returning that.

Danny Kukawka e1f4c485cd eicon: fix -Warray-bounds warning
Fix for a -Warray-bounds warning. mixer_notify_update() tries to
write to ((CAPI_MSG *) msg)->info.facility_req.structs[3] while
structs is defined as byte structs[1]. Set all 'structs' which are
part of the typdefs in the info union to 'byte structs[0]'.

Rusty Russell 90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Added bonus is that it removes some unneeded kernel log messages about

After the last patch, We are left in a state in which only drivers calling
ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real
hardware call ether_setup for their net_devices and don't hold any state in
their skbs.  There are a handful of drivers that violate this assumption of
course, and need to be fixed up.  This patch identifies those drivers, and marks
them as not being able to support the safe transmission of skbs by clearning the
IFF_TX_SKB_SHARING flag in priv_flags

Phil Carmody 497888cf69 treewide: fix potentially dangerous trailing ';' in #defined values/expressions
All these are instances of
  #define NAME value;
or
  #define NAME(params_opt) value;

These of course fail to build when used in contexts like
  if(foo $OP NAME)
  while(bar $OP NAME)
and may silently generate the wrong code in contexts such as
  foo = NAME + 1;    /* foo = value; + 1; */
  bar = NAME - 1;    /* bar = value; - 1; */
  baz = NAME & quux; /* baz = value; & quux; */

Reported on comp.lang.c,
Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com>
Initial analysis of the dangers provided by Keith Thompson in that thread.

There are many more instances of more complicated macros having unnecessary
trailing semicolons, but this pile seems to be all of the cases of simple
values suffering from the problem. (Thus things that are likely to be found
in one of the contexts above, more complicated ones aren't.)

Pavel Shved 2f9381e984 gigaset: call module_put before restart of if_open()
if_open() calls try_module_get(), and after an attempt to lock a mutex
the if_open() function may return -ERESTARTSYS without
putting the module.  Then, when if_open() is executed again,
try_module_get() is called making the reference counter of THIS_MODULE
greater than one at successful exit from if_open().  The if_close()
function puts the module only once, and as a result it can't be
unloaded.

This patch adds module_put call before the return from if_open().

Linus Torvalds 55db4c64ed Revert "tty: make receive_buf() return the amout of bytes received"
This reverts commit b1c43f82c5.

It was broken in so many ways, and results in random odd pty issues.

It re-introduced the buggy schedule_work() in flush_to_ldisc() that can
cause endless work-loops (see commit a5660b41af6a: "tty: fix endless
work loop when the buffer fills up").

It also used an "unsigned int" return value fo the ->receive_buf()
function, but then made multiple functions return a negative error code,
and didn't actually check for the error in the caller.

And it didn't actually work at all.  BenH bisected down odd tty behavior
to it:
  "It looks like the patch is causing some major malfunctions of the X
   server for me, possibly related to PTYs.  For example, cat'ing a
   large file in a gnome terminal hangs the kernel for -minutes- in a
   loop of what looks like flush_to_ldisc/workqueue code, (some ftrace
   data in the quoted bits further down).

   ...

   Some more data: It -looks- like what happens is that the
   flush_to_ldisc work queue entry constantly re-queues itself (because
   the PTY is full ?) and the workqueue thread will basically loop
   forver calling it without ever scheduling, thus starving the consumer
   process that could have emptied the PTY."

which is pretty much exactly the problem we fixed in a5660b41af.

Milton Miller pointed out the 'unsigned int' issue.

Prarit Bhargava 367bbf2aa1 isdn: netjet - blacklist Digium TDM400P

A quick google search reveals that people with this card are blacklisting it
in the initramfs and in the module blacklist based on a statement that it
is unsupported. Since the older Digium is also unsupported I'm pretty
confident that this newer card is also not supported.

Jesper Juhl 2393c944d5 ISDN, Gigaset: Fix memory leak in do_disconnect_req()
Hi,

In drivers/isdn/gigaset/capi.c::do_disconnect_req() we will leak the
memory allocated (with kmalloc) to 'b3cmsg' if the call to alloc_skb()
fails.

...
		b3cmsg = kmalloc(sizeof(*b3cmsg), GFP_KERNEL);
	allocation here ------^
		if (!b3cmsg) {
			dev_err(cs->dev, "%s: out of memory\n", __func__);
			send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
			return;
		}
		capi_cmsg_header(b3cmsg, ap->id, CAPI_DISCONNECT_B3, CAPI_IND,
				 ap->nextMessageNumber++,
				 cmsg->adr.adrPLCI | (1 << 16));
		b3cmsg->Reason_B3 = CapiProtocolErrorLayer1;
		b3skb = alloc_skb(CAPI_DISCONNECT_B3_IND_BASELEN, GFP_KERNEL);
		if (b3skb == NULL) {
			dev_err(cs->dev, "%s: out of memory\n", __func__);
			send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
			return;
	leak here ------^
...

This leak is easily fixed by just kfree()'ing the memory allocated to
'b3cmsg' right before we return. The following patch does that.

flush_scheduled_work() is deprecated and will be removed.  Because
kcapi uses fire-and-forget type works, it's impossible to flush each
work explicitly.  Create and use a dedicated workqueue instead.

Please note that with recent workqueue changes, each workqueue doesn't
reserve a lot of resources and using it as a flush domain is fine.

Looking into it I found that the stack was corrupted by the assignment
of the Rev #. The variable rev is given 10 bytes, and in this output the
characters that were copied was: " 1.65.6.8 $". Which was 11 characters
plus the null ending character for a total of 12 bytes, thus corrupting
the stack.

This patch ups the variable size to 20 bytes as well as changes the
strcpy to strncpy. I also added a check to make sure '$' is found.

Eric Dumazet 93aaae2e01 filter: optimize sk_run_filter
Remove pc variable to avoid arithmetic to compute fentry at each filter
instruction. Jumps directly manipulate fentry pointer.

As the last instruction of filter[] is guaranteed to be a RETURN, and
all jumps are before the last instruction, we dont need to check filter
bounds (number of instructions in filter array) at each iteration, so we
remove it from sk_run_filter() params.

On x86_32 remove f_k var introduced in commit 57fe93b374
(filter: make sure filters dont read uninitialized memory)

Note : We could use a CONFIG_ARCH_HAS_{FEW|MANY}_REGISTERS in order to
avoid too many ifdefs in this code.

This helps compiler to use cpu registers to hold fentry and A
accumulator.

On x86_32, this saves 401 bytes, and more important, sk_run_filter()
runs much faster because less register pressure (One less conditional
branch per BPF instruction)

Julia Lawall 4101e976e0 drivers/isdn: delete double assignment
Delete successive assignments to the same location.  In the first case, the
hscx array has two elements, so change the assignment to initialize the
second one.  In the second case, the two assignments are simply identical.
Furthermore, neither is necessary, because the effect of the assignment is
only visible in the next line, in the assignment in the if test.  The patch
inlines the right hand side value in the latter assignment and pulls that
assignment out of the if test.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Arnd Bergmann 6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Dan Carpenter b530fb69cf isdn: strcpy() => strlcpy()
setup.phone and setup.eazmsn are 32 character buffers.
rcvmsg.msg_data.byte_array is a 48 character buffer.
sc_adapter[card]->channel[rcvmsg.phy_link_no - 1].dn is 50 chars.

The rcvmsg struct comes from the memcpy_fromio() in receivemessage().
I guess that means it's data off the wire.  I'm not very familiar with
this code but I don't see any reason to assume these strings are NULL
terminated.

Also it's weird that "dn" in a 50 character buffer but we only seem to
use 32 characters.  In drivers/isdn/sc/scioc.h, "dn" is only a 49
character buffer.  So potentially there is still an issue there.

The important thing for now is to prevent the memory corruption.

The "clients[id].drvName" is a 128 character buffer and
"clients[id].Dbg.drvName" was originally a 16 character buffer but I've
changed it to 128 as well.  We don't actually use 128 characters but we
do use more than 16.

I've also changed the size of "tmp" to 128 characters instead of 256.

Tilman Schmidt f3d531b99f isdn/gigaset: correct bas_gigaset rx buffer handling
In transparent data reception, avoid a NULL pointer dereference
in case an skbuff cannot be allocated, remove an inappropriate
call to the HDLC flush routine, and correct the accounting of
received bytes for continued buffers.

Dominik Brodowski 2262054e74 pcmcia: remove obsolete and wrong comments
What's worse than no comment? A wrong comment.

Several PCMCIA device drivers contained the same comments, which
were based on how the PCMCIA subsystem worked in the old days of 2.4.,
and which were originally part of a "dummy_cs" driver. These comments
no longer matched at all what is happening now, and therefore should
be removed.

Dominik Brodowski 00990e7ce0 pcmcia: use autoconfiguration feature for ioports and iomem
When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding
fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
accordinly. Drivers wishing to override certain settings may do so in
the callback function, but they no longer need to parse the CIS entries
stored in cistpl_cftable_entry_t themselves.

pcmcia_enable_device() now replaces pcmcia_request_configuration().
Instead of config_req_t, all necessary flags are either passed as

set in struct pcmcia_device -> flags.

With the last remaining user of include/pcmcia/cs.h gone, remove

Dominik Brodowski 37979e1546 pcmcia: simplify IntType
IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
(all other drivers). As this flags seems to relate to ioport access, make
it conditional to the driver having requested IO port access. There are two
drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

to CONF_ENABLE_SPKR; the latter can be simplified to setting this

The isdn4linux driver uses the big kernel lock only
to serialize access to a few fields in its own
modem_info structure.

The easiest replacement is a driver-wide mutex.
More fine-grained locking would be more appropriate
here, but likely harder to implement.
