2012-07-166lowpan: Change byte order when storing/accessing to len fieldTony Cheneau
Lenght field should be encoded using big endian byte order, such as intend in the specs. As it is currently written, the len field would not be decoded properly on an implementation using the correct byte ordering. Hence, it could lead to interroperability issues. Also, I rewrote the code so that iphc0 argument of lowpan_alloc_new_frame could be removed. Signed-off-by: Tony Cheneau <tony.cheneau@amnesiak.org> Signed-off-by: David S.

2012-07-166lowpan: Change byte order when storing/accessing u16 tagTony Cheneau
The tag field should be stored and accessed using big endian byte order (as intended in the specs). Or else, when displayed with a trafic analyser, such a Wireshark, the field not properly displayed (e.g. 0x01 00 instead of 0x00 01, and so on).

2012-07-166lowpan: Fix null pointer dereference in UDP uncompression functionTony Cheneau
When a UDP packet gets fragmented, a crash will occur at reassembly time. This is because skb->transport_header is not set during earlier period of fragment reassembly. As a consequence, call to udp_hdr() return NULL and uh (which is NULL) gets dereferenced without much test. Signed-off-by: Tony Cheneau <tony.cheneau@amnesiak.org> Signed-off-by: David S.

2012-07-126lowpan: rework fragment-deleting routinealex.bluesman.smirnov@gmail.com
6lowpan module starts collecting incomming frames and fragments right after lowpan_module_init() therefor it will be better to clean unfinished fragments in lowpan_cleanup_module() function instead of doing it when link goes down. Changed spinlocks type to prevent deadlock with expired timer event and removed unused one. Signed-off-by: Alexander Smirnov <alex.bluesman.smirnov@gmail.com> Signed-off-by: David S.

2012-07-126lowpan: fix tag variable sizealex.bluesman.smirnov@gmail.com
Function lowpan_alloc_new_frame() takes u8 tag as an argument. However, its only caller, lowpan_process_data() passes down a u16. Hence, the tag value can get corrupted. This prevent 6lowpan fragment reassembly of a message when the fragment tag value is over 256.

net: Remove all uses of LL_ALLOCATED_SPACE The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the alignment to the sum of needed_headroom and needed_tailroom. As the amount that is then reserved for head room is needed_headroom with alignment, this means that the tail room left may be too small.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.
