| | | | | | | | | | | | | Indentation cleanup resulting from the cleanup of #ifdefs. The conscious decision was made not to perform any indentation or whitespace cleanup while cleaning out old redunant #ifdefs. The reason for this was to avoid confusing future readers of history and diffs with cosmetic changes, making bisection of any possible bugs introduced more difficult. This commit cleans up the whitespace detritus left behind from the previous #ifdef cleanup commits. (cherry picked from commit 7071734fae6019d1e3e44daf7deb4478582081cc)

| | | | | | | | | | | Retire the K&R/STD C __P prototype declarations. In the old days when K&R C and STD C were each in use a workaround (read hack) was required to allow the same code to work on each without modification. All C compilers support STD C. We can finally put the __P prototype to rest. (cherry picked from commit 4cd1807c7d2a67b633dd0c0bfde15091543a2514)

* Remove FirstBurstLength limit for software iSCSI.Alexander Motin2021-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | For hardware offload solicited data may potentially be handled more efficiently than unsolicited due to direct data placement. Or there can be some unsolicited write buffering limitations. It may create situations where FirstBurstLength limit is really useful. Software driver though has no those factors, having to do memcopy() any way and having no so hard limit on the temporary storage. Same time more active use of unsolicited transfers allows to avoid some of Ready To Transfer (R2T) PDU round-trip times and processing. This change effectively doubles from 64KB to 128KB the maximum size of write command that can be transferred within one link RTT. Tests of (64KB, 128KB] QD1 writes mixed with simultaneous QD8 reads over the same connection, increasing RTT, shows almost double write speed and half latency, while we should be able to afford few megabytes of RAM for additional buffering on a target these days.

Move from using git rev-list --count to git rev-lis --count --first-parent since that gives a better, incrementing number. 2. Report this count as 'nXXXXX' rather than 'cXXXXX' because c is part of a hash and we've changed the sematnics of XXXXX 3. Remove g to make HASH cut and pastable. Durting review, #1 & #3 had the largest consensus. There was a diversity of opinion on #2, but on the whole it was positive so I'll acknowledge the dissent, but move forward with something seems to have support since the dissent was all about what letter to use where I chose 'n'.

* opencrypto: Fix assignment of crypto completions to worker threadsMark Johnston2021-02-031-1/+4
| | | | | | | | | | | | | | | | | | Since r336439 we simply take the session pointer value mod the number of worker threads (ncpu by default). On small systems this ends up funneling all completion work through a single thread, which becomes a bottleneck when processing IPSec traffic using hardware crypto drivers. (Software drivers such as aesni(4) are unaffected since they invoke completion handlers synchonously.) Instead, maintain an incrementing counter with a unique value per session, and use that to distribute work to completion threads.

* cxgb(4): Remove assumption of physically contiguous mbufs.Alexander Motin2021-02-033-36/+5
| | | | | | | | | | | | | | | | | | | Investigation of iSCSI target data corruption reports brought me to discovery that cxgb(4) expects mbufs to be physically contiguous, that is not true after I've started using m_extaddref() in software iSCSI for large zero-copy transmissions. In case of fragmented memory the driver transmitted garbage from pages following the first one due to simple use of pmap_kextract() for the first pointer instead of proper bus_dmamap_load_mbuf_sg(). Seems like it was done as some optimization many years ago, and at very least it is wrong in a world of IOMMUs. This patch just removes that optimization, plus limits packet coalescing for mbufs crossing page boundary, also depending on assumption of one segment per packet. Sponsored by: iXsystems, Inc.

* fstyp(8): Show exFAT volume labels with -l flagConrad Meyer2021-02-026-12/+367
| | | | | | | | | | | | | | | | | | | | | | | | | | exfat is fundamentally the same design as fat32. The superblock differs marginally, and there are some additional optional features irrelevant to fstype(8); the structure of dirents has changed slightly to enable, among other things, larger files; the directory entries are no longer DOS 8.3 ASCII or local 8-bit encoding, but instead explicitly UCS-2-LE. (As a result, this change uses iconv to convert a found exfat volume label to the user's locale.) Locating the volume label is identical to FAT32: locate the root directory and walk through dirents until you find a volume label. Like FAT32, follow the FAT chain between root directory clusters as necessary.
