      Name resolution, wildcarded FSEntry_File 5 & 9, and buffer overrun fixes · 517c6bdb
      Robert Sprowson authored
      Make SMB_RxWords a bit bigger per static anaylsis
      when LONGNAMES is undefined, since NT LM 0.12 dialect is allowed at the same time as short names.
      A change to name translation in LanManFS-2_60 broke all forms of nested contentious name resolution, ie. where a leafname containing a contentious character was itself in a directory containing one.
      The cited problem names ('1 2/3' and '1 /s') can both be resolved at one level only, no 2nd pass is required. The resolution function walks along the elements of the path one at a time to reach the leaf (ie. no element is processed twice). A test case has been created to allow some regression testing when making future changes in this area.
      When building tboxlibint
        Copy h.* <Lib$Dir>.tboxlibint.h.*
      when the directory is empty FileSwitch checks the destination ending in ...\h\* which the short names translation would error with ENOWILDCARD, but the long names translation attempts to resolve it by finding the trailing '\' and appending a '*' (ie. not doing anything), this returns no results and is passed back unfaulted. The special check in fsentry_file() for ENOWILDCARD for the two ReadCatalogueInformation thus doesn't trigger, and an attempt to FileGetAttribs() is made on the still wildcarded path. This is rejected by the server when in SMB_GetAttribsX2() does a TRANSACT2_QUERYPATHINFORMATION, which expects a non wildcarded object (on Windows servers at least), propagating an error back up to the user.
      This stopped a ROM build from completing the exports phase via LanManFS on a Windows share.
      Const-ify a few things.
      Changed files
        Xlate.c: Revert change from revision 1.21, return ENOWILDCARD when appropriate.
        SMC.c: Increase MAX_WCT buffer size to 17.
        UK/CmdHelp: Add some missing chevrons round the command syntax for required parameters.
        test/Contentious: Test case for nested contentious character resolution code.

      Fix for truncating writes to servers that declare MaxBufferSize >= 64k smb.c,... · e6b73849
      Robert Sprowson authored
      Fix for truncating writes to servers that declare MaxBufferSize >= 64k smb.c, lines 2726 onwards: when chopping up the next buffer, make sure the size sent still fits in the SMB_COM_WRITE count field (16 bits). For completeness, make sure the estimate of bytes remaining is similarly saturated too.
      smb.c, lines 2711-2713: cifs-v1-spec-02 section 5.27 says the server always expects to receive up to 65535 bytes, so this test should not be subject to the negotiated MaxBufferSize, and is expected to often exceed it. Currently we use 32k, if this is ever increased we really ought to take into account MaxRawSize that the server tells us.
      Tested with a handful of files of power-of-2 sizes and odd sizes. Inspection in Wireshark looks OK. Variation of a diagnosis by Will Ling https://www.riscosopen.org/forum/forums/4/topics/8966

      Robert Sprowson authored
      The PRM entry for Free reason 1 is very vague, it requires the length of the drive name including a terminator, not strlen() of the drive name. Free uses this directly to allocate RMA to copy into (though for drive names that aren't a multiple of 8 we're saved by OS_Module rounding up claims).
      Also use Free SWI values from headers rather than defining them again locally.

      Add a quick exit for the timeout=0 case · e5ce78dc
      Robert Sprowson authored
      Careful analysis of packet captures by Colin Granville reveals that LanManFS waits for at least 1cs when no timeout was requested, so add a quick exit for that case. Timeouts of >= 1cs still delay for at least the requested time, and up to 0.999cs longer as before.
      This reduces the turn around time which is most beneficial for interfaces faster than 10baseT.

      Ammendments to short name translation table · 478370c8
      Robert Sprowson authored
      The table was ambiguously translating () to () and also [] to (). Now, we error names containing ,[] in the same manner as DOSFS.
      The substitutions for ^% have also been changed to match DOSFS so copying from one to the other doesn't give two representations if viewed on a PC.
      Marked both tables as const to save 512B of RMA.
      This change is slightly academic since most of the time the long filename resolution is in use.

      Make name cache flush unconditional · 22f3ec34
      Robert Sprowson authored
      The size returned by OS_File 5 might not match the size shown in the Filer viewer (or via *EX) because the last cached version was being returned. This would manifest itself as an error from !Edit if the file on the server had grown since last queried, when loading the file the amount of memory reserved was for the smaller (stale cache copy size).
      The name cache is now always flushed on exit from the FileSwitch functions, this doesn't alter performance because the size was already being queried across the network, it was just that the result was overridden by the cached copy.
      Be more robust and only capture the default driver name when it starts up.
      This could be a problem if LanManFS starts after the ethernet driver, and the value of Inet$EtherType is unset. When the driver dies LanManFS would have taken that name as the default - leading to "Bad parameter" when trying to connect to a share.
      Tested on IOMD with WinXP SP3.

      Removed verbose mode · 8a3f55c4
      Robert Sprowson authored
      With LanManFS in ROM it's not actually possible to enable verbose mode, since it relies on command arguments being passed to it on initialisation. Since RMREINIT doesn't allow that you can't ever pass '-v'. Even the RAM loaded case isn't that useful, since the verbose text is output via printf() which doesn't appear in the desktop (with OmniClient).
      Swap the few uses of verbose mode to route via DebugLib instead, controlled via the 'DEBUG' predefine.

      Fix and speed up EXT#handle=number doing nothing when number is beyond 2GB · 18a0315a
      Robert Sprowson authored
      Internally LanManFS was representing file offsets and data lengths as signed numbers, while in general this doesn't matter (they are passed through opaquely as just numbers and not manipulated) in a couple of places they were being used as while () loop exit conditions.
      Function WriteZeroes (used when extending a file via OS_Args) therefore never performed the call to SMB_Write when beyond 2G because the loop condition was never met.
      Additionally, it was literally transferring buffers of zeros across the network which is unnecessary as the server is documented as doing a zero fill itself, this represents at least a x40 speed up (on a slow 1MB/s drive write speed at the server end) or more.
      Changed offset & lengths from int to uint.
      Added the earlier CIFS spec (the later copy is missing section 5 for some reason) to docs.

      Robert Sprowson authored
      When a file ended in ',xxx' (unfinished DEADDEAD) or ',lxa' (load/execution addresses) LanManFS was correctly identifying these internally but at the last moment OR'd the result unconditionally with 0xFFF00000 when calculating the date stamp/access attributes.
      Now, an unstamped file will propagate the load & exec addresses properly.

      Fix for *INFO dates not matching *EX dates · a0fb97c2
      Robert Sprowson authored
      These two displays take different code paths, and *INFO goes via a check to workaround a bug in Win98 servers. Unfortunately, the check no longer works because Microsoft don't return the '.' and '..' entries in SMB Trans2 FIND_FIRST, and the logic previously always set the "need to frig the dates" flag. Now, the flag is only set if something comes back and after doing a test swap the results are also correct.
      Turned on the 'auto close Trans2 FIND_FIRST' flag in the request block to save having to do a second transaction to close it.
      Swapped the LDMFD/STMFD for Push and Pull in the assembler.
      Tested against WinXP SP3, dates are no longer bonkers.

       Added an extra check after the Xlate path resolution code so that
       the case of the path given to resolve is honoured. This now means that
       the strcmp() done in SMB_Rename fails and the rename is actually sent to
       the server. Before "*rename test Test" would have the path resolved and
       since 'test' already existed both names would be the same, in this example
       something like "*rename A:\test A:\test" would result.
       Made the non LONGNAMES version compile again (not tested).
       Removed local definitions of FSControl reason codes, uses Interface header

      Workaround for NTFS returning resume keys of zero. · d1ca5496
      Robert Sprowson authored
        When the underlying FS is NTFS, eg. WinXP Pro, the requested
        resume keys for a directory search are always zero - this is passed
        back via OSGBPB and on the next call it triggers a new search. So
        we get stuck in an infinite loop.
        Now checks for a resume key stuck at zero, and makes a fake one static
        to the search context then sets the continuation bit in the SMB_FIND_NEXT
        call because the server returning the duff key remembers the position.
        Dir_CallbackFn could return with "taken" undefined. Move a few lines
        Missing "#else" added to CHECK_ARMBOOT_EXISTS so if this is disabled
        no further attempt is made to find !ArmBoot.
        Couple of typos corrected.
        Spelling of "disk" changed to "disc" in an error message.
        Tested with XP Pro SP3 with NTFS, directories which previously hung
        the filer now open correctly. Checked with XP Home SP3 with FAT32 to
        verify behaviour unchanged from 2.32.
        Note, with large directories the initial path translation triggers a
        dir search too which takes ages compared with the actual number of
        entries returned. This could be cached to make counting far faster.
