2010-02-16CAPI: Rework controller state notifierJan Kiszka
Another step towards proper locking: Rework the callback provided to capidrv for controller state changes. This is so far attached to an application, which would require us to hold the corresponding lock across notification calls. But there is no direct relation between a controller up/down event and an application, so let's decouple them and provide a notifier call chain for those events instead. This notifier chain is first of all used internally. Here we request the highest priority to unsure that housekeeping work is done before any other notifications. The chain is exported via [un]register_capictr_notifier to our only user, capidrv, to replace the racy and unfixable capi20_set_callback.

2010-02-16CAPI: Reduce chattiness during module loading/removalJan Kiszka
The CVS revisions dumped by all CAPI modules are meaningless today. And that some CAPI module is loaded or removed does not necessarily deserve a message. Just keep the message of the central module, capi.ko, drop the rest. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-01-14proc_fops: convert drivers/isdn/ to seq_fileAlexey Dobriyan
Convert code away from ->read_proc/->write_proc interfaces. Switch to proc_create()/proc_create_data() which make addition of proc entries reliable wrt NULL ->proc_fops, NULL ->data and so on.

2009-10-06isdn: avoid races in capidrvTilman Schmidt
In several places, capidrv sends a CAPI message to the ISDN device and then updates its internal state accordingly. If the response message from the device arrives before the state is updated, it may be rejected or processed incorrectly. Avoid these races by updating the state before emitting the message.

2007-10-16fix possible NULL deref on low memory condition in capidrv.c::send_message()Jesper Juhl
If we fail to allocate an skb in drivers/isdn/capi/capidrv.c::send_message(), then we'll end up dereferencing a NULL pointer. Since out of memory conditions are not unheard of, I believe it is better to print a error message and just return rather than bring down the whole kernel. Sure, doing this may upset some application, but that's still better than crashing the whole system.

2007-03-01[PATCH] Fix buffer overflow and races in capi debug functionsKarsten Keil
The CAPI trace debug functions were using a fixed size buffer, which can be overflowed if wrong formatted CAPI messages were sent to the kernel capi layer. The code was also not protected against multiple callers. This fix bug 8028. Additionally the patch make the CAPI trace functions optional.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
