Exposing these pointers provides an\neasy target for kernel write vulnerabilities, since they reveal the\nlocations of writable structures containing easily triggerable function\npointers. The behavior of %pK depends on the kptr_restrict sysctl.\n\nIf kptr_restrict is set to 0, no deviation from the standard %p behavior\noccurs. If kptr_restrict is set to 1, the default, if the current user\n(intended to be a reader via seq_printf(), etc.) does not have CAP_SYSLOG\n(currently in the LSM tree), kernel pointers using %pK are printed as 0\u0027s.\n If kptr_restrict is set to 2, kernel pointers using %pK are printed as\n0\u0027s regardless of privileges. Replacing with 0\u0027s was chosen over the\ndefault \"(null)\", which cannot be parsed by userland %p, which expects\n\"(nil)\".\n\nThe supporting code for kptr_restrict and %pK are currently in the -mm\ntree. This patch converts users of %p in net/ to %pK. Cases of printing\npointers to the syslog are not covered, since this would eliminate useful\ninformation for postmortem debugging and the reading of the syslog is\nalready optionally protected by the dmesg_restrict sysctl.\n\nSigned-off-by: Dan Rosenberg \u003cdrosenberg@vsecurity.com\u003e\nCc: James Morris \u003cjmorris@namei.org\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Thomas Graf \u003ctgraf@infradead.org\u003e\nCc: Eugene Teo \u003ceugeneteo@kernel.org\u003e\nCc: Kees Cook \u003ckees.cook@canonical.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: David S.

Didn\u0027t think kcalloc added a GFP_ZERO the way kzalloc did :)\n\nSummary:\nIt was shown to me recently that systems under high load were driven very deep\ninto swap when tcpdump was run. The reason this happened was because the\nAF_PACKET protocol has a SET_RINGBUFFER socket option that allows the user space\napplication to specify how many entries an AF_PACKET socket will have and how\nlarge each entry will be. It seems the default setting for tcpdump is to set\nthe ring buffer to 32 entries of 64 Kb each, which implies 32 order 5\nallocation. Thats difficult under good circumstances, and horrid under memory\npressure.\n\nI thought it would be good to make that a bit more usable. I was going to do a\nsimple conversion of the ring buffer from contigous pages to iovecs, but\nunfortunately, the metadata which AF_PACKET places in these buffers can easily\nspan a page boundary, and given that these buffers get mapped into user space,\nand the data layout doesn\u0027t easily allow for a change to padding between frames\nto avoid that, a simple iovec change is just going to break user space ABI\nconsistency.\n\nSo I\u0027ve done this, I\u0027ve added a three tiered mechanism to the af_packet set_ring\nsocket option. It attempts to allocate memory in the following order:\n\n1) Using __get_free_pages with GFP_NORETRY set, so as to fail quickly without\ndigging into swap\n\n2) Using vmalloc\n\n3) Using __get_free_pages with GFP_NORETRY clear, causing us to try as hard as\nneeded to get the memory\n\nThe effect is that we don\u0027t disturb the system as much when we\u0027re under load,\nwhile still being able to conduct tcpdumps effectively.\n\nTested successfully by me.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nAcked-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nAcked-by: Maciej Żenczykowski \u003czenczykowski@gmail.com\u003e\nReported-by: Maciej Żenczykowski \u003czenczykowski@gmail.com\u003e\nSigned-off-by: David S.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros.

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.

In addition\nthe socket create methods are modified so that they will fail if\nyou attempt to create a socket in a non-default network namespace.\n\nFailing if we attempt to create a socket outside of the default\nnetwork namespace ensures that as we incrementally make the network stack\nnetwork namespace aware we will not export functionality that someone\nhas not audited and made certain is network namespace safe.\nAllowing us to partially enable network namespaces before all of the\nexotic protocols are supported.\n\nAny protocol layers I have missed will fail to compile because I now\npass an extra parameter into the socket creation code.\n\n[ Integrated AF_IUCV build fixes from Andrew Morton... -DaveM ]\n\nSigned-off-by: Eric W.
