- Attempt to gracefully recover from a failed decrease_reservation or
increase_reservation, by avoiding physical memory loss.
- always store a machine address in ds_addr; this avoids some mistakes
where machine address would in some case be freed at physical address, or
mapped as physical address.
If you perform this request on a directory with exactly 50 files
(plus '.' and '..' which brings the total to 52 objects), the first
reply for the SMB server completely satisfies the query (server
side is Windows 2000 Professional).
The smbfs client then performs a TRANS2_FIND_NEXT2 using the last
file name as the resume key. The response returns a SearchCount
of zero (ctx->f_ecnt == 0) and an EndOfSearch code of zero.
Any attempt to get more entries with calls to TRANS2_FIND_NEXT2
result in Badfid (bad file descriptor). I suspect the return of
SearchCount of zero means that end-of-search has been reached and
the Sid is now closed.
The solution is to set "SMB_RDD_EOF | SMB_RDD_NOCLOSE" after getting
back a zero SearchCount, I've tested this in the field on a quite
a few systems, aggressively accessing Windows shares over smbfs
and it appears flawless.
I was initially concerned about the possibility of resource exhaustion
on the Windows server. I was afraid by not officially closing the
search, it would leave a resource hung-up and over time, exhaust
some sort of "open search table" limit. I've since convinced myself
this is NOT the case.
Windows needs to be able to handle clients that come and go over
time. If the search is not closed, Windows will close it if it
finds it needs more resources. I've testing this on directory
searches descending into 10's of thousands of folders, with 100's
of thousands of files.
sharing of code with the AR5315, which has many similarities, but many
differences from the AR5312.
No functional change at this time, other than the cpu_model string
(and also sysctl.hw.model node) is changed to reflect the WiSoC cpu
name rather than the identification string in ROM (which tends to not
be very informative.)
