* fs: Don't allow to create hardlink for deleted fileAneesh Kumar K.V2011-03-15
| | | | | | | | | | | Add inode->i_nlink == 0 check in VFS. Some of the file systems do this internally. A followup patch will remove those instance. This is needed to ensure that with link by handle we don't allow to create hardlink of an unlinked file. The check also prevent a race between unlink and link Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* New AT_... flag: AT_EMPTY_PATHAl Viro2011-03-14
| | | | | | | | | | For name_to_handle_at(2) we'll want both ...at()-style syscall that would be usable for non-directory descriptors (with empty relative pathname). Introduce new flag (AT_EMPTY_PATH) to deal with that and corresponding LOOKUP_EMPTY; teach user_path_at() and path_init() to deal with the latter. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* open-style analog of vfs_path_lookup()Al Viro2011-03-14
| | | | | | | | | | | | | new function: file_open_root(dentry, mnt, name, flags) opens the file vfs_path_lookup would arrive to. Note that name can be empty; in that case the usual requirement that dentry should be a directory is lifted. open-coded equivalents switched to it, may_open() got down exactly one caller and became static.

* reduce vfs_path_lookup() to do_path_lookup()Al Viro2011-03-14
| | | | | | | | | | | | | | | New lookup flag: LOOKUP_ROOT. nd->root is set (and held) by caller, path_init() starts walking from that place and all pathname resolution machinery never drops nd->root if that flag is set. That turns vfs_path_lookup() into a special case of do_path_lookup() *and* gets us down to 3 callers of link_path_walk(), making it finally feasible to rip the handling of trailing symlink out of link_path_walk(). That will not only simply the living hell out of it, but make life much simpler for unionfs merge. Trailing symlink handling will become iterative, which is a good thing for stack footprint in a lot of situations as well. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* untangle do_lookup()Al Viro2011-03-14
| | | | | | | | | | | | | | | | | | | | | | That thing has devolved into rats nest of gotos; sane use of unlikely() gets rid of that horror and gives much more readable structure: * make a fast attempt to find a dentry; false negatives are OK. In RCU mode if everything went fine, we are done, otherwise just drop out of RCU. If we'd done (RCU) ->d_revalidate() and it had not refused outright (i.e. didn't give us -ECHILD), remember its result. * now we are not in RCU mode and hopefully have a dentry. If we do not, lock parent, do full d_lookup() and if that has not found anything, allocate and call ->lookup(). If we'd done that ->lookup(), remember that dentry is good and we don't need to revalidate it. * now we have a dentry. If it has ->d_revalidate() and we can't skip it, call it. * hopefully dentry is good; if not, either fail (in case of error) or try to invalidate it. If d_invalidate() has succeeded, drop it and retry everything as if original attempt had not found a dentry. * now we can finish it up - deal with mountpoint crossing and automount.

* do_last: kill a rudiment of old ->d_revalidate() workaroundAl Viro2011-03-14
| | | | | | | | | | | | There used to be time when ->d_revalidate() couldn't return an error. So intents code had lookup_instantiate_filp() stash ERR_PTR(error) in nd->intent.open.filp and had it checked after lookup_hash(), to catch the otherwise silent failures. That had been introduced by commit 4af4c52f34606bdaab6930a845550c6fb02078a4. These days ->d_revalidate() can and does propagate errors back to callers explicitly, so this check isn't needed anymore.

* switch non-create side of open() to use of do_last()Al Viro2011-03-14
| | | | | | | | | | | | | | | | | | | | Instead of path_lookupat() doing trailing symlink resolution, use the same scheme as on the O_CREAT side. Walk with LOOKUP_PARENT, then (in do_last()) look the final component up, then either open it or return error or, if it's a symlink, give the symlink back to path_openat() to be resolved there. The really messy complication here is RCU. We don't want to drop out of RCU mode before the final lookup, since we don't want to bounce parent directory ->d_count without a good reason. Result is _not_ pretty; later in the series we'll clean it up. For now we are roughly back where we'd been before the revert done by Nick's series - top-level logics of path_openat() is cleaned up, do_last() does actual opening, symlink resolution is done uniformly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 567aba0b7997dad5fe3fb4aeb174ee9018df8c5b, the probe address for tda8290_probe and tda8295_probe was hard-coded to 0x4b, which is the default i2c address for those devices, but its possible for the device to be at an alternate address, 0x42, which is the case for the HVR-1950. If we probe the wrong address, probe fails and we have a non-working device. We have the actual address passed into the function by way of i2c_props, we just need to use it. Also fix up some copy/paste comment issues and streamline debug spew a touch. Verified to restore my HVR-1950 to full working order.

I came across a post from Andy in March (http://www.gossamer-threads.com/lists/ivtv/users/40943#40943) where he speculates that perhaps the corrective actions being taken after a DMA ERROR are not sufficient to recover the situation. After some testing I suspect that this is indeed the case, and that in fact the corrective action may be what hangs the card's DMA engine, rather than the original error. Specifically these DMA ERROR IRQs seem to present with two different values in the IVTV_REG_DMASTATUS register: 0x11 and 0x13. The current corrective action is to clear that status register back to 0x01 or 0x03, and then issue the next DMA request. In the case of a 0x13 this seems to result in a minor glitch in the encoded stream due to the failed transfer that was not retried, but otherwise things continue OK. In the case of a 0x11 the card's DMA write engine is never heard from again, and a DMA TIMEOUT follows shortly after. 0x11 is the killer. I suspect that the two cases need to be handled differently. The difference is in bit 1 (0x02), which is set when the error is about to be successfully recovered, and clear when things are about to go bad. Bit 1 of DMASTATUS is described differently in different places either as a positive "write finished", or an inverted "write busy". If we take the first definition, then when an error arises with state 0x11, it means that the write did not complete. It makes sense to start a new transfer, as in the current code. But if we take the second definition, then 0x11 means "an error but the write engine is still busy". Trying to feed it a new transfer in this situation might not be a good idea. As an experiment, I added code to ignore the DMA ERROR IRQ if DMASTATUS is 0x11. I.e., don't start a new transfer, don't clear our flags, etc. The hope was that the card would complete the transfer and issue a ENC DMA COMPLETE, either successfully or with an error condition there. However the card still hung. The only remaining corrective action being taken with a 0x11 status was then the write back to the status register to clear the error, i.e. DMASTATUS = DMASTATUS & ~3. This would have the effect of clearing the error bit 4, while leaving the lower bits indicating DMA write busy. Strangely enough, removing this write to the status register solved the problem! If the DMA ERROR IRQ with DMASTATUS=0x11 is completely ignored, with no corrective action at all, then the card will complete the transfer and issue a new IRQ. If the status register is written to when it has the value 0x11, then the DMA engine hangs. Perhaps it's illegal to write to DMASTATUS while the read or write busy bit is set? At any rate, it appears that the current corrective action is indeed making things worse rather than better. I put together a patch that modifies ivtv_irq_dma_err to do the following: - Don't write back to IVTV_REG_DMASTATUS. - If write-busy is asserted, leave the card alone. Just extend the timeout slightly. - If write-busy is de-asserted, retry the current transfer. This has completely fixed my DMA TIMEOUT woes. DMA ERR events still occur, but now they seem to be correctly handled. 0x11 events no longer hang the card, and 0x13 events no longer result in a glitch in the stream, as the failed transfer is retried. I'm happy. I've inlined the patch below in case it is of interest. As described above, I have a theory about why it works (based on a different interpretation of bit 1 of DMASTATUS), but I can't guarantee that my theory is correct. There may be another explanation, or it may be a fluke. Maybe ignoring that IRQ entirely would be equally effective? Maybe the status register read/writeback sequence is race condition if the card changes it in the mean time? Also as I am using a PVR-150 only, I have not been able to test it on other cards, which may be especially relevant for 350s that support concurrent decoding. Hopefully the patch does not break the DMA READ path. Mike [awalls@md.metrocast.net: Modified patch to add a verbose comment, make minor brace reformats, and clear the error flags in the IVTV_REG_DMASTATUS iff both read and write DMA were not in progress. Mike's conjecture about a race condition with the writeback is correct; it can confuse the DMA engine.] [Comment and analysis from the ML post by Michael <mike@rsy.com>] Signed-off-by: Andy Walls <awalls@md.metrocast.net> Cc: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
