| | | | | | | | | | | | | | | Similar to how qeth currently does early L2 setup of OSM and OSN devices, add support for early setup of L3-only devices. This adds a qeth_l3_devtype that contains all core and l3-specific sysfs attributes, so that they can be created in one go while probing. This just adds the infrastructure, exploitation of the support happens in a subsequent patch.

* s390/qeth: fix retrieval of vipa and proxy-arp addressesUrsula Braun2017-01-121-14/+16
| | | | | | | | | | | | | | | | | | qeth devices in layer3 mode need a separate handling of vipa and proxy-arp addresses. vipa and proxy-arp addresses processed by qeth can be read from userspace. Introduced with commit 5f78e29ceebf ("qeth: optimize IP handling in rx_mode callback") the retrieval of vipa and proxy-arp addresses is broken, if more than one vipa or proxy-arp address are set. The qeth code used local variable "int i" for 2 different purposes. This patch now spends 2 separate local variables of type "int". While touching these functions hash_for_each_safe() is converted to hash_for_each(), since there is no removal of hash entries.

* qeth: optimize IP handling in rx_mode callbackLakhvich Dmitriy2016-06-161-40/+38
| | | | | | | | | | | | | | | | | In layer3 mode of the qeth driver, multicast IP addresses from struct net_device and other type of IP addresses from other sources require mapping to the OSA-card. This patch simplifies the IP address mapping logic, and changes imple- mentation of ndo_set_rx_mode callback and ip notifier events. Addresses are stored in private hashtables instead of lists now. It allows hardware registration/removal for new/deleted multicast addresses only.

* clean up scary strncpy(dst, src, strlen(src)) usesKees Cook2013-07-031-4/+2
| | | | | | | | | | | | | | | | | | | | | | | Fix various weird constructions of strncpy(dst, src, strlen(src)). Length limits should be about the space available in the destination, not repurposed as a method to either always include or always exclude a trailing NULL byte. Either the NULL should always be copied (using strlcpy), or it should not be copied (using something like memcpy). Readable code should not depend on the weird behavior of strncpy when it hits the length limit. Better to avoid the anti-pattern entirely.

| | | | | | | | | | | | | | | | | | This patch extends the HiperSockets device driver to send and receive af_iucv traffic over HiperSockets transport.

If receiver is not capable to clean its buffers shared with HiperSockets and pass new memory to the HiperSockets layer this will cause flow control/congestion events on the sender.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
