If the (sub)system\n can somehow continue operating, perhaps with reduced functionality,\n it\u0027s probably not BUG-worthy.\n\n If you\u0027re tempted to BUG(), think again: is completely giving up\n really the *only* solution? There are usually better options, where\n users don\u0027t need to reboot ASAP and can mostly shut down cleanly.\n\nIn our case, the status flag of a ring buffer slot is managed from both sides,\nthe kernel space and the user space. This means that even though the kernel\nside might work as expected, the user space screws up and changes this flag\nright between the send(2) is triggered when the flag is changed to\nTP_STATUS_SENDING and a given skb is destructed after some time. Then, this\nwill hit the BUG macro. As David suggested, the best solution is to simply\nremove this statement since it cannot be used for kernel side internal\nconsistency checks.

The\nintroduction of socket queue overflow reporting [1] changed drop\nrate calculation in the normal packet socket path, but not when using a\npacket ring. As a result, the getsockopt now returns different statistics\ndepending on the reception method used. With a ring, it still returns the\ncount since the last call, as counts are incremented in tpacket_rcv and\nreset in getsockopt. Without a ring, it returns 0 if no drops occurred\nsince the last getsockopt and the total drops over the lifespan of\nthe socket otherwise. The culprit is this line in packet_rcv, executed\non a drop:\n\ndrop_n_acct:\n po-\u003estats.tp_drops \u003d atomic_inc_return(\u0026sk-\u003esk_drops);\n\nAs it shows, the new drop number it taken from the socket drop counter,\nwhich is not reset at getsockopt. I put together a small example\nthat demonstrates the issue [2]. It runs for 10 seconds and overflows\nthe queue/ring on every odd second. The reported drop rates are:\nring: 16, 0, 16, 0, 16, ...\nnon-ring: 0, 15, 0, 30, 0, 46, 0, 60, 0 , 74.\n\nNote how the even ring counts monotonically increase. Because the\ngetsockopt adds tp_drops to tp_packets, total counts are similarly\nreported cumulatively. Long story short, reinstating the original code, as\nthe below patch does, fixes the issue at the cost of additional per-packet\ncycles. Another solution that does not introduce per-packet overhead\nis be to keep the current data path, record the value of sk_drops at\ngetsockopt() at call N in a new field in struct packetsock and subtract\nthat when reporting at call N+1. I\u0027ll be happy to code that, instead,\nit\u0027s just more messy.\n\n[1] http://patchwork.ozlabs.org/patch/35665/\n[2] http://kernel.googlecode.com/files/test-packetsock-getstatistics.c\n\nSigned-off-by: Willem de Bruijn \u003cwillemb@google.com\u003e\nSigned-off-by: 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. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "1162563f82b434e3099c9e6c1bbdba846d792f0d", "tree": "3903e4265740f2b2049615d7178aa434252bf5f3", "parents": [ "9fe969345b10931319b3f1e7034fbdeb786de234" ], "author": { "name": "Jiri Pirko", "email": "jpirko@redhat.com", "time": "Tue Mar 02 20:40:01 2010 +0000" }, "committer": { "name": "David S.
