2016-03-05isdn: i4l: move active-isdn drivers to stagingArnd Bergmann
The icn, act2000 and pcbit drivers are all for very old hardware, and it is highly unlikely that anyone is actually still using them on modern kernels, if at all. All three drivers apparently are for hardware that predates PCI being the common connector, as they are ISA-only and active PCI ISDN cards were widely available in the 1990s. Looking through the git logs, it I cannot find any indication of a patch to any of these drivers that has been tested on real hardware, only cleanups or global API changes.

2014-07-31ISDN: pcbit: off by one bugs in pcbit_set_msn()Dan Carpenter
1) We don't allocate enough space for the NUL terminator so we end up corrupting one character beyond the end of the buffer. 2) The "len - 1" should just be "len". The code is trying to copy a word from a buffer up to a comma or the last word in the buffer. Say you have the buffer, "foo,bar,baz", then this code truncates the last letter off each word so you get "fo", "ba", and "ba". You would hope this kind of bug would get noticed in testing... I'm not very familiar with this code and I can't test it, but I think we should copy the final character. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

2014-02-26isdn: pcbit: fix interruptible_sleep_on raceArnd Bergmann
interruptible_sleep_on is racy and going away. In case of pcbit, the driver would run into a timeout if the card is initialized before we start waiting for it. This uses wait_event to fix the race. In order to do this, the state machine handling for the timeout case has to get trivially reorganized so we actually know whether the timeout has occorred or not.

2012-02-21isdn: whitespace coding style cleanupJoe Perches
isdn source code uses a not-current coding style. Update the coding style used on a per-line basis so that git diff -w shows only elided blank lines at EOF. Done with emacs and some scripts and some typing. Built x86 allyesconfig. No detected change in objdump -d or size. Signed-off-by: Joe Perches <joe@perches.com>
2010-05-31drivers/isdn: Use memdup_userJulia Lawall
Use memdup_user when user data is immediately copied into the allocated region. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; position p; identifier l1,l2; @@ - to = \(kmalloc@p\|kzalloc@p\)(size,flag); + to = memdup_user(from,size); if ( - to==NULL + IS_ERR(to) || ...) { <+... when != goto l1; - -ENOMEM + PTR_ERR(to) ...+> } - if (copy_from_user(to, from, size) != 0) { - <+... when != goto l2; - -EFAULT - ...+> - } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2009-10-11headers: remove sched.h from interrupt.hAlexey Dobriyan
After m68k's task_thread_info() doesn't refer to current, it's possible to remove sched.h from interrupt.h and not break m68k! Many thanks to Heiko Carstens for allowing this. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
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-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!
