This means that the\ncycle start packet will be assumed to be self ID data, and will be\nstored after the actual self ID quadlets in the self ID buffer.\n\nThis garbage in the self ID buffer made firewire-core ignore all of the\nself ID data, and thus prevented the Linux bus manager from correcting\nthe problem. Furthermore, because the bus reset handling was aborted\ncompletely, asynchronous transfers would be no longer handled correctly,\nand fw_run_transaction() would hang until the next bus reset.\n\nTo fix this, make the detection of inconsistent self IDs more\ndiscriminating: If the invalid data in the self ID buffer looks like\na cycle start packet, we can assume that the previous data in the buffer\nis correctly received self ID information, and process it normally.\n\n(We inspect only the first quadlet of the cycle start packet, because\nthis value is different enough from any valid self ID quadlet, and many\ncontrollers do not store the cycle start packet in five quadlets because\nthey expect self ID data to have an even number of quadlets.)\n\nThis bug has been observed when a bus-powered DesktopKonnekt6 is\nswitched off with its power button.\n\nSigned-off-by: Clemens Ladisch \u003cclemens@ladisch.de\u003e\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "a74477db9171e677b7a37b89e6e0ac8a15ba1f26", "tree": "72f6a3ba84ef8db0bcbb58c75384e2aa9ccd1c9f", "parents": [ "4ec4a67aa100268b4ac5ae32b54843d975969969" ], "author": { "name": "Stephan Gatzka", "email": "stephan@gatzka.org", "time": "Mon Sep 26 21:44:30 2011 +0200" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Sun Oct 09 17:00:18 2011 +0200" }, "message": "firewire: net: Use posted writes\n\nChange memory region to ohci \"middle address space\".

Consequently, programs like kino or\ndvgrab are unaware of the presence of a camcorder.\n\nSuch transaction failures happen also with the ieee1394 driver stack\n(of the 2.4...2.6 kernel series until 2.6.36 inclusive) but with a lower\nlikelihood, such that kino or dvgrab are generally able to use these\ncamcorders via the older driver stack. The cause for firewire-ohci\u0027s or\nfirewire-core\u0027s worse behavior is not yet known. Gap count optimization\nin firewire-core is not the cause. Perhaps the slightly higher latency\nof transaction completion in the older stack plays a role. (ieee1394:\nAR-resp DMA context tasklet -\u003e packet completion ktread -\u003e user process;\nfirewire-core: tasklet -\u003e user process.)\n\nThis change introduces retries and delays after ack_busy_X into\nfirewire-core\u0027s Config ROM reader, such that at least firewire-core\u0027s\nprobing and /dev/fw* creation are successful. This still leaves the\nproblem that userland processes are facing transaction failures.\ngscanbus\u0027s built-in retry routines deal with them successfully, but\nneither kino\u0027s nor dvgrab\u0027s do ever succeed.\n\nBut at least DV capture with \"dvgrab -noavc -card 0\" works now. Live\nvideo preview in kino works too, but not actual capture.\n\nOne way to prevent Configuration ROM reading failures in application\nprograms is to modify libraw1394 to synthesize read responses by means\nof firewire-core\u0027s Configuration ROM cache. This would only leave\nCMP and FCP transaction failures as a potential problem source for\napplications.\n\nReported-and-tested-by: Thomas Seilund \u003ctps@netmaster.dk\u003e\nReported-and-tested-by: René Fritz \u003crene@colorcube.de\u003e\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "a01e836087881dd9d824417190994c9b2b0f1dbb", "tree": "dba049b83137d4cda2fdc53ed06d83897a74dc4f", "parents": [ "9c1176b6a28850703ea6e3a0f0c703f6d6c61cd3" ], "author": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Thu Aug 11 20:40:42 2011 +0200" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Fri Aug 12 15:30:08 2011 +0200" }, "message": "firewire: ohci: fix DMA unmapping in an error path\n\nIf request_irq failed, we would pass wrong arguments to\ndma_free_coherent. https://bugzilla.redhat.com/show_bug.cgi?id\u003d728185\n\nReported-by: Mads Kiilerich\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "9c1176b6a28850703ea6e3a0f0c703f6d6c61cd3", "tree": "5e51f0e7e36c78ae63e3128125cb008bcc442aa0", "parents": [ "9a00c24ae7cb08dcd46edf1327a47871e8466444" ], "author": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Thu Aug 11 00:06:04 2011 +0200" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Fri Aug 12 15:30:08 2011 +0200" }, "message": "firewire: cdev: fix 32 bit userland on 64 bit kernel compat corner cases\n\nClemens points out that we need to use compat_ptr() in order to safely\ncast from u64 to addresses of a 32-bit usermode client.\n\nBefore, our conversion went wrong\n - in practice if the client cast from pointer to integer such that\n sign-extension happened, (libraw1394 and libdc1394 at least were not\n doing that, IOW were not affected)\nor\n - in theory on s390 (which doesn\u0027t have FireWire though) and on the\n tile architecture, regardless of what the client does.\nThe bug would usually be observed as the initial get_info ioctl failing\nwith \"Bad address\" (EFAULT).\n\nReported-by: Carl Karsten \u003ccarl@personnelware.com\u003e\nReported-by: Clemens Ladisch \u003cclemens@ladisch.de\u003e\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "60063497a95e716c9a689af3be2687d261f115b4", "tree": "6ce0d68db76982c53df46aee5f29f944ebf2c320", "parents": [ "148817ba092f9f6edd35bad3c6c6b8e8f90fe2ed" ], "author": { "name": "Arun Sharma", "email": "asharma@fb.com", "time": "Tue Jul 26 16:09:06 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jul 26 16:49:47 2011 -0700" }, "message": "atomic: use \u003clinux/atomic.h\u003e\n\nThis allows us to move duplicated code in \u003casm/atomic.h\u003e\n(atomic_inc_not_zero() for now) to \u003clinux/atomic.h\u003e\n\nSigned-off-by: Arun Sharma \u003casharma@fb.com\u003e\nReviewed-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nAcked-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "441c196e84b11aad3123baa9320eee7abc6b5c98" }
