So a proper d_revalidate method that calls d_drop\nalso needs to call have_submounts which is moderately expensive, so you\nreally don\u0027t want a d_revalidate method that unconditionally calls it, but\ninstead only calls it when the backing object has really gone away.\n\nproc generic entries only disappear on module_unload (when not counting the\nfledgling network namespace) so it is quite rare that we actually encounter\nthat case and has not actually caused us real world trouble yet.\n\nSo until we get a proper test for keeping dentries in the dcache fix the\ncurrent d_revalidate method by completely removing it. This returns us to\nthe current status quo.\n\nSo with CONFIG_NETNS\u003dn things should look as they have always looked.\n\nFor CONFIG_NETNS\u003dy things work most of the time but there are a few rare\ncorner cases that don\u0027t behave properly.

ENOENT\n is for inodes that are no longer valid and we just skip them. EINVAL is\n returned if we try to lookup an internal inode so we skip them too. For\n a DMF scan if the inode and DMF attribute cannot fit into the space left\n in the user\u0027s buffer it would return ERANGE. We didn\u0027t handle this error\n and skipped the inode. We would continue to skip inodes until one fitted\n into the user\u0027s buffer or we completed the scan.\n- put back the recalculation of agino (that got removed with the last fix)\n at the end of the while loop. This is because the code at the start of\n the loop expects agino to be the last inode examined if it is non-zero.\n- if we found some inodes but then encountered an error, return success\n this time and the error next time.

Unconscious\nones are flushes that occur as a side effect of some other operation or\ndue to memory pressure.\n\nCurrently, when an error occurs during an unconscious flush (ENOSPC or\nEIO), we toss out the page and don\u0027t preserve that error to report to\nthe user when a conscious flush occurs. If after the unconscious flush,\nthere are no more dirty pages for the inode, the conscious flush will\nsimply return success even though there were previous errors when writing\nout pages. This can lead to data corruption.\n\nThe easiest way to reproduce this is to mount up a CIFS share that\u0027s\nvery close to being full or where the user is very close to quota. mv\na file to the share that\u0027s slightly larger than the quota allows. The\nwrites will all succeed (since they go to pagecache). The mv will do a\nsetattr to set the new file\u0027s attributes. This calls\nfilemap_write_and_wait,\nwhich will return an error since all of the pages can\u0027t be written out.\nThen later, when the flush and release ops occur, there are no more\ndirty pages in pagecache for the file and those operations return 0. mv\nthen assumes that the file was written out correctly and deletes the\noriginal.\n\nCIFS already has a write_behind_rc variable where it stores the results\nfrom earlier flushes, but that value is only reported in cifs_close.\nSince the VFS ignores the return value from the release operation, this\nisn\u0027t helpful. We should be reporting this error during the flush\noperation.\n\nThis patch does the following:\n\n1) changes cifs_fsync to use filemap_write_and_wait and cifs_flush and also\nsync to check its return code. If it returns successful, they then check\nthe value of write_behind_rc to see if an earlier flush had reported any\nerrors. If so, they return that error and clear write_behind_rc.\n\n2) sets write_behind_rc in a few other places where pages are written\nout as a side effect of other operations and the code waits on them.\n\n3) changes cifs_setattr to only call filemap_write_and_wait for\nATTR_SIZE changes.\n\n4) makes cifs_writepages accurately distinguish between EIO and ENOSPC\nerrors when writing out pages.\n\nSome simple testing indicates that the patch works as expected and that\nit fixes the reproduceable known problem.\n\nAcked-by: Dave Kleikamp \u003cshaggy@austin.rr.com\u003e\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "2a97468024fb5b6eccee2a67a7796485c829343a", "tree": "98675977be018528ceb6dea5a0f634d4053478a4", "parents": [ "f7a44eadd5a03b8455c7caab402ce96811c6903d" ], "author": { "name": "Petr Tesarik", "email": "ptesarik@suse.cz", "time": "Tue Nov 20 02:24:08 2007 +0000" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Tue Nov 20 02:24:08 2007 +0000" }, "message": "[CIFS] Fix spurious reconnect on 2nd peek from read of SMB length\n\nWhen retrying kernel_recvmsg() because of a short read, check returned\nlength against the remaining length, not against total length.

This difference causes the NFS client to BUG.\n\nI think the best way to fix this is to trap this possibility early, so\njust before completing the mount in the NFS client, check that it isn\u0027t\ngoing to use nfs_mountpoint_inode_operations.\nAs long as i_op will never change once set (is that true?), this\nshould be adequately safe.\n\nThe following patch shows a possible approach, and it works for me.\ni.e. when the NFS server is misbehaving, I get ESTALE on those\nmountpoints, while when the NFS server is working correctly, I get\ncorrect behaviour on the client.\n\nNeilBrown\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "b09b9417d074e01a4e4ab5c19358f1b3dc76c1b2", "tree": "ed90c600222d35834b045e8a72336621d36f0b2e", "parents": [ "2ffbb8377c7a0713baf6644e285adc27a5654582" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Thu Oct 25 13:56:10 2007 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Nov 17 13:08:44 2007 -0500" }, "message": "NFS: Fix the ustat() regression\n\nSince 2.6.18, the superblock sb-\u003es_root has been a dummy dentry with a\ndummy inode.
