Ok, starting to make sense now. In order to fix it.... I note that the lower level calls are wrapped in dir.c - eg dptr_SeekDir(...) wraps SeekDir(...) this might allow for some code to use array indexes instead of NFS cookies as noted by Chris Chilvers here for the 3.10 kernel: https://lore.kernel.org/all/CAAmbk-e-YQAPo6QyNB0aJyc9qzUShmEC+x5eTR7wqp1ABWADsg at mail.gmail.com/T/ > On the older 3.10 kernel, this was not...

Alternately, we could possibly modify the dptr_TellDir function to set a flag somewhere if it ever returns a negative offset. Then any calls to dptr_SeekDir checks if the flag is set and does a slower approach of a RewindDir and then multiple ReadDir & TellDir calls until we get the matching offset. If flag is not set then go with the normal SeekDir call??? On Fri, 17 Feb 2023 at 00:40, Conor Armstrong <conorarmstrong at gmail.com> wrote:...

...the client response. No worries, we saved off the 'offset = telldir()' before doing the readdir that returned filename "m". So we seek back to the offset before the filename "m" in this code: if (NT_STATUS_EQUAL(status, STATUS_MORE_ENTRIES)) { dptr_SeekDir(dirptr, prev_dirpos); return status; } and return the findfirst reply with files a-l. Now when the listing continues, it'll do so with filename "m" etc. until the listing is done. If: offset = telldir() seekdir(offset) doesn't return us to the same p...

I'm trying to get to the bottom of where the normal directory functions differ in results for block storage compared to NFS. I created a short c script to look at the offsets generated for the directory when block storage backed in comparison to NFS backed. block storage backed are always positive: File: 5050, Offset: 9213006461214587617 File: 6567, Offset: 9218690536865144001 File: 4033,

Jeremy, I think we found the part of source where the problem resides: smbd/trans2.c +1444 for (i=0;(i<maxentries) && !finished && !out_of_space;i++) { +1445 BOOL got_exact_match = False; +1446 +1447 /* this is a heuristic to avoid seeking the dirptr except when +1448 absolutely necessary. It allows for
