* Make taskstats round statistics down to nearest 1k bytes/eventsLinus Torvalds2011-09-201-7/+8
| | | | | | | | | Even with just the interface limited to admin, there really is little to reason to give byte-per-byte counts for taskstats. So round it down to something less intrusive. Acked-by: Balbir Singh <bsingharora@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* Make TASKSTATS require root accessLinus Torvalds2011-09-201-0/+1
| | | | | | | | | | | | | | | Ok, this isn't optimal, since it means that 'iotop' needs admin capabilities, and we may have to work on this some more. But at the same time it is very much not acceptable to let anybody just read anybody elses IO statistics quite at this level. Use of the GENL_ADMIN_PERM suggested by Johannes Berg as an alternative to checking the capabilities by hand.

|\ | | | | | | | | * 'slab/urgent' of git://github.com/penberg/linux: slub: add slab with one free object to partial list tail
| * slub: add slab with one free object to partial list tailShaohua Li2011-08-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The slab has just one free object, adding it to partial list head doesn't make sense. And it can cause lock contentation. For example, 1. CPU takes the slab from partial list 2. fetch an object 3. switch to another slab 4. free an object, then the slab is added to partial list again In this way n->list_lock will be heavily contended. In fact, Alex had a hackbench regression. 3.1-rc1 performance drops about 70% against 3.0. This patch fixes it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BO blit code inconsistenly handled the page size. This wasn't an issue on system with 4k pages since the GPU's page size is 4k as well. Switch the driver blit callbacks to take num pages in GPU page units. Fixes lemote mipsel systems using AMD rs780/rs880 chipsets. v2: incorporate suggestions from Michel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current IPv6 implementation uses inetpeer to store metrics for routes. The problem of inetpeer is that it doesn't take subnet prefix length in to consideration. If two routes have the same address but different prefix length, they share same inetpeer. So changing metrics of one route also affects the other. The fix is to allocate separate metrics storage for each route. Signed-off-by: Zheng Yan <zheng.z.yan@intel.com> Signed-off-by: David S.

So allow 0x16d6 as the matching checksum on HPPA systems. This issue is present on longterm/stable kernels, I have verified that this patch is applicable back to at least 2.6.32.y kernels. v2- changed ifdef to use CONFIG_PARISC instead of __hppa__ CC: Guy Martin <gmsoft@tuxicoman.be> CC: Rolf Eike Beer <eike-kernel@sf-tec.de> CC: Matt Turner <mattst88@gmail.com> Reported-by: Mikulas Patocka <mikulas@artax.kerlin.mff.cuni.cz> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Acked-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: David S.

Relax the check, but make sure the bind() is done on INADDR_ANY addresses, as AF_UNSPEC has probably no sane meaning for other addresses.

This problem was previously fixed via 64507fdbc29c3a622180378210ecea8659b14e40 (netfilter: nf_queue: fix NF_STOLEN skb leak) but this had to be reverted because NF_STOLEN can also be returned by a netfilter hook when iterating the rules in nf_reinject. Reject userspace NF_STOLEN verdict, as suggested by Michal Miroslaw. This is complementary to commit fad54440438a7c231a6ae347738423cbabc936d9 (netfilter: avoid double free in nf_reinject).

We allocate memory for 'skb' with alloc_skb() annd then call nlh = NLMSG_PUT(skb, 0, 0, IPQM_PACKET, size - sizeof(*nlh)); NLMSG_PUT is a macro NLMSG_PUT(skb, pid, seq, type, len) \ NLMSG_NEW(skb, pid, seq, type, len, 0) that expands to NLMSG_NEW, which is also a macro which expands to: NLMSG_NEW(skb, pid, seq, type, len, flags) \ ({ if (unlikely(skb_tailroom(skb) < (int)NLMSG_SPACE(len))) \ goto nlmsg_failure; \ __nlmsg_put(skb, pid, seq, type, len, flags); }) If we take the true branch of the 'if' statement and 'goto nlmsg_failure', then we'll, at that point, return from ipq_build_packet_message() without having assigned 'skb' to anything and we'll leak the memory we allocated for it when it goes out of scope. Fix this by placing a 'kfree(skb)' at 'nlmsg_failure'. I admit that I do not know how likely this to actually happen or even if there's something that guarantees that it will never happen - I'm not that familiar with this code, but if that is so, I've not been able to spot it.
