This value was\nexported via a SOL_PACKET level cmsg. AFter I completed that work it was\nrequested that this feature be generalized so that any datagram oriented socket\ncould make use of this option. As such I\u0027ve created this patch, It creates a\nnew SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a\nSOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue\noverflowed between any two given frames. It also augments the AF_PACKET\nprotocol to take advantage of this new feature (as it previously did not touch\nsk-\u003esk_drops, which this patch uses to record the overflow count). Tested\nsuccessfully by me.\n\nNotes:\n\n1) Unlike my previous patch, this patch simply records the sk_drops value, which\nis not a number of drops between packets, but rather a total number of drops.\nDeltas must be computed in user space.\n\n2) While this patch currently works with datagram oriented protocols, it will\nalso be accepted by non-datagram oriented protocols. I\u0027m not sure if thats\nagreeable to everyone, but my argument in favor of doing so is that, for those\nprotocols which aren\u0027t applicable to this option, sk_drops will always be zero,\nand reporting no drops on a receive queue that isn\u0027t used for those\nnon-participating protocols seems reasonable to me. This also saves us having\nto code in a per-protocol opt in mechanism.\n\n3) This applies cleanly to net-next assuming that commit\n977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.

Specifically the requestors want to\nsee where in a packet sequence frames were lost, i.e. they want to see that 40\nframes were lost between frames 302 and 303 in a packet capture file. In order\nto do this we need:\n\n1) The kernel to export this data to user space\n2) The applications to make use of it\n\nThis patch addresses item (1). It does this by doing the following:\n\nA) Anytime we drop a frame for which we would increment po-\u003estats.tp_drops, we\nalso no increment a stats called po-\u003estats.tp_gap.\n\nB) Every time we successfully enqueue a frame to sk_receive_queue, we record the\nvalue of po-\u003estats.tp_gap in skb-\u003emark. skb-\u003ecb would nominally be the place to\nrecord this, but since all the space there is used up, we\u0027re overloading\nskb-\u003emark. Its safe to do since any enqueued packet is guaranteed to be\nunshared at this point, and skb-\u003emark isn\u0027t used for anything else in the rx\npath to the application. After we record tp_gap in the skb, we zero\npo-\u003estats.tp_gap. This allows us to keep a counter of the number of frames lost\nbetween any two enqueued packets\n\nC) When the application goes to dequeue a frame from the packet socket, we look\nat skb-\u003emark for that frame. If it is non-zero, we add a cmsg chunk to the\nmsghdr of level SOL_PACKET and type PACKET_GAPDATA. Its a 32 bit integer that\nrepresents the number of frames lost between this packet and the last previous\nframe received.\n\nNote there is a chance that if there is frame loss after a receive, and then the\nsocket is closed, some gap data might be lost. This is covered by the use of\nthe PACKET_AUXDATA socket option, which gives total loss data. With a bit of\nmath, the final gap can be determined that way.\n\nI\u0027ve tested this patch myself, and it works well.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\n\n include/linux/if_packet.h | 2 ++\n net/packet/af_packet.c | 33 +++++++++++++++++++++++++++++++++\n 2 files changed, 35 insertions(+)\nSigned-off-by: David S.

Now, event counter per memcg is updated only when\n memory usage is over soft limit. Here, considering hierarchical memcg\n management, ancesotors should be taken care of.\n\n Now, ancerstors(hierarchy) are handled in charge() but not in uncharge().\n This is not good.\n\n Prolems:\n 1. memcg\u0027s event counter incremented only when softlimit hits. That\u0027s bad.\n It makes event counter hard to be reused for other purpose.\n\n 2. At uncharge, only the lowest level rescounter is handled. This is bug.\n Because ancesotor\u0027s event counter is not incremented, children should\n take care of them.\n\n 3. res_counter_uncharge()\u0027s 3rd argument is NULL in most case.\n ops under res_counter-\u003elock should be small. No \"if\" sentense is better.\n\nFixes:\n * Removed soft_limit_xx poitner and checks in charge and uncharge.\n Do-check-only-when-necessary scheme works enough well without them.\n\n * make event-counter of memcg incremented at every charge/uncharge.\n (per-cpu area will be accessed soon anyway)\n\n * All ancestors are checked at soft-limit-check. This is necessary because\n ancesotor\u0027s event counter may never be modified.

Opening a tty that is closing (and\n could be closing for long periods) is supposed to return -EIO.\n\n I suspect a better way to deal with this and keep the old console\n timing is to split tty-\u003eshutdown into two functions.\n\n tty-\u003eshutdown() - called synchronously just before we dump the tty\n onto the waitqueue for destruction\n\n tty-\u003ecleanup() - called when the destructor runs.\n\n We would then do the shutdown part which can occur in IRQ context\n fine, before queueing the rest of the release (from tty-\u003emagic \u003d 0\n ... the end) to occur asynchronously\n\n The USB update in -next would then need a call like\n\n if (tty-\u003ecleanup)\n tty-\u003ecleanup(tty);\n\n at the top of the async function and the USB shutdown to be split\n between shutdown and cleanup as the USB resource cleanup and final\n tidy cannot occur synchronously as it needs to sleep.\n\n In other words the logic becomes\n\n final kref put\n make object unfindable\n\n async\n clean it up\n\nSigned-off-by: Dave Young \u003chidave.darkstar@gmail.com\u003e\n[ rjw: Rebased on top of 2.6.31-git, reworked the changelog. ]\nSigned-off-by: \"Rafael J.

This scheme should introduce no extra\noverhead in the fork path when there\u0027s no contention.\n\nThe final patch reveals potential for a race when forking before a\nsubsystem\u0027s attach function is called - one potential solution in case any\nsubsystem has this problem is to hang on to the group\u0027s fork mutex through\nthe attach() calls, though no subsystem yet demonstrates need for an\nextended critical section.\n\nThis patch:\n\nRevert\n\ncommit 096b7fe012d66ed55e98bc8022405ede0cc80e96\nAuthor: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nAuthorDate: Wed Jul 29 15:04:04 2009 -0700\nCommit: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCommitDate: Wed Jul 29 19:10:35 2009 -0700\n\n cgroups: fix pid namespace bug\n\nThis is in preparation for some clashing cgroups changes that subsume the\noriginal commit\u0027s functionaliy.\n\nThe original commit fixed a pid namespace bug which Ben Blum fixed\nindependently (in the same way, but with different code) as part of a\nseries of patches. I played around with trying to reconcile Ben\u0027s patch\nseries with Li\u0027s patch, but concluded that it was simpler to just revert\nLi\u0027s, given that Ben\u0027s patch series contained essentially the same fix.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: \"Eric W.
