[cifs-protocol] [Pfif] SMB1 Trans2SetPathInfo() FileEndOfFileInformation is not enforcing share modes

[Bill Wesse]

I have retested without SmbSecuritySignatures - results were the same.

I will hold off on the WordCount/ByteCount truncation against the Dos INVALID_LEVEL error problem (trans2setpathinfo_against_win7_2.pcap) for the time being, and work on the sharing issue (I expect to be soaking in code for the next day or so).

Thanks for all your help with samba4/smbtorture (I am still having problems with gz on my Ubuntu client, so I unpacked it on my Windows client & cloned the tree to Ubuntu). No problems at all with the build.

Good morning Tim. I have successfully reproduced the share problem with Trans2SetPathInfo() FileEndOfFileInformation, using smbtorture (RAW-SFILEINFO-END-OF-FILE ) against both Windows 2008 R2 and Windows 7. This, of course, will allow me to dig deeper into the problem.

Interestingly, WordCount/ByteCount truncation against the Dos INVALID_LEVEL error problem (trans2setpathinfo_against_win7_2.pcap) you saw did not reproduce with my clients (who succeeded against the ); the only significant difference I see in the traces you sent and my test traces is that my Win7/R2 targets were using SmbSecuritySignatures (your Win7 client did not).

I have attached my network captures (in both Wireshark tcp dump & Netmon 3.x format).

I will retry with security signatures disabled and get back to you with the results.
