* x25: remove the BKLArnd Bergmann2011-03-053-43/+23
| | | | | | | | | | | | | | | | | | This replaces all instances of lock_kernel in x25 with lock_sock, taking care to release the socket lock around sleeping functions (sock_alloc_send_skb and skb_recv_datagram). It is not clear whether this is a correct solution, but it seem to be what other protocols do in the same situation. Includes a fix suggested by Eric Dumazet.

* x25: possible skb leak on bad facilitiesandrew hendry2011-02-072-12/+30
| | | | | | | | | | | | | | | | | | | | Originally x25_parse_facilities returned -1 for an error 0 meaning 0 length facilities >0 the length of the facilities parsed. 5ef41308f94dc ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more error checking in x25_parse_facilities however used 0 to indicate bad parsing a6331d6f9a429 ("memory corruption in X.25 facilities parsing") followed this further for DTE facilities, again using 0 for bad parsing. The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts. So patch makes all parsing errors return -1 and ensures callers close and don't use the skb further.

| * x25: decrement netdev reference counts on unloadApollon Oikonomopoulos2010-12-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | x25 does not decrement the network device reference counts on module unload. Thus unregistering any pre-existing interface after unloading the x25 module hangs and results in unregister_netdevice: waiting for tap0 to become free. Usage count = 1 This patch decrements the reference counts of all interfaces in x25_link_free, the way it is already done in x25_link_device_down for NETDEV_DOWN events.

| | | | | | | | | | | | | | Now with improved comma support. On parsing malformed X.25 facilities, decrementing the remaining length may cause it to underflow.

* | BKL: introduce CONFIG_BKL.Arnd Bergmann2010-10-211-0/+1
|/ | | | | | | | | | | | | | | | | | | With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-308-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* | x.25 attempts to negotiate invalid throughputJohn Hughes2010-04-072-7/+28

It does negotiation in all cases, usually there is no need 2. It incorrectly attempts to negotiate the throughput class in one direction only. There are separate throughput classes for input and output and if either is negotiated both mist be negotiates. This is bug https://bugzilla.kernel.org/show_bug.cgi?id=15681 This bug was first reported by Daniel Ferenci to the linux-x25 mailing list on 6/8/2004, but is still present. The current (2.6.34) x.25 code doesn't seem to know that the X.25 throughput facility includes two values, one for the required throughput outbound, one for inbound. This causes it to attempt to negotiate throughput 0x0A, which is throughput 9600 inbound and the illegal value "0" for inbound throughput. Because of this some X.25 devices (e.g. Cisco 1600) refuse to connect to Linux X.25. The following patch fixes this behaviour. Unless the user specifies a required throughput it does not attempt to negotiate. If the user does not specify a throughput it accepts the suggestion of the remote X.25 system. If the user requests a throughput then it validates both the input and output throughputs and correctly negotiates them with the remote end.

| * net/x25: push BKL usage into x25_protoArnd Bergmann2009-11-071-11/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The x25 driver uses lock_kernel() implicitly through its proto_ops wrapper. The makes the usage explicit in order to get rid of that wrapper and to better document the usage of the BKL. The next step should be to get rid of the usage of the BKL in x25 entirely, which requires understanding what data structures need serialized accesses.
