The upstream NBD protocol recently clarified that servers can advertise block size limitations to clients that ask with NBD_OPT_GO (although we're still a ways off from implementing that in nbdkit); and that in the absence of that, then clients should agree on limits using out-of-band information or stick to sane defaults (everything 512-byte-aligned, no reads or writes larger than 32M).

Does anyone know of a way to log when a user logs off using Samba as a PDC. I have Samba 3.0.2a and can log log-ons using root preexec on a share all users mount, however I do not know of a way to log log-offs. We need this data for record keeping purposes. We don't use roaming profiles, so using root postexec is not an option as shares disconne...

...ressing modes... I assume you're trying to get an alignment value for the 'reg' part, without the "immed" part? This approach would have a couple of problems. Instead, if you wanted a more general alignment model, I'd suggest going for representing alignments as "offset from alignment". In this model, you represent each alignment value as a pair <align,offs>, where offs is always less than align. This allows you to say that "this load is 2 bytes away from a 16-byte aligned pointer" for example. -Chris -- http://nondot.org/sabre/ http...

Hi, For EAs data structure in inode/block are little different from them in bucket. These two patches try to make them same for the most part. The first patch set xh_free_start and xh_name_value_len when EAs in inode/block. xh_free_start is useful to keep the minimum offset of the xattr name/value. But xh_name_value_len is not very useful because we don't have "hole" when EAs in inode/block, we just calculate and set it here, maybe it's useful for fsck. The second patch reserve a blank space between xattr entry and name/value when EAs in bucke...

Hello Thanks to Frank Harrell for the great Design package. I noted from Pencina's Article (Statistics in Medicine Vol 27, pp157-172) that the result obtained for the Net Reclassification Index depends upon categorical cut-offs for risk (eg in the paper <6%, 6-20% and >20%). I wondered how the improveprob function arrives at its cut-offs, and whether there was any function to change the default cut-offs used. Thanks for any help you can offer. Yours sincerely David McAllister **********************************...

Hi all, I'm experiencing weird cutoffs on TE110P. All cut offs are pre-seen with an indication 5 coming from the PRI. I've talked to the telco, and they indicated that they don't see any issues. I've also modified the sync source to be the telco, and that didn't solve the problem either. Any ideas anybody ? Nir S

Based on Rich's review of my v1 that touched only cache.c, I have now tried to bring all three filters with alignment rounding in line with one another. There is definitely room for future improvements once we teach nbdkit to let filters and plugins advertise block sizes, but I'm hoping to get NBD_CMD_CACHE implemented first.

This patch will improve the flow at disk_write_sectors and disk_read_sectors. It does that by creating a table of values respective to the operation. Besides, read and write operations are pretty similar to each other, so I redesigned the routines to avoid duplication.

When querying the extents of the underlying plugin, we should only translate the starting offset, and let the plugin report for at least as many bytes as our range permits. Otherwise, short-changing the range causes bad behavior such as returning 0 extents, or even failing the creation of an extents tracker: $ cat script case "$1" in get_size) echo 1m;; can_extents) ;;...

Nicholas, I guess you're trying to solve the fragile base-class problem by deferring field offset calculations until JIT compilation time? Perhaps I'm missing something, but can't you accomplish this by using external constants in the source program, to be supplied at JIT/link time? external constant i32 @obj.x.offs; external constant i32 @obj.y.offs; define flo...
