* Fix several performance related issues in the new NFS server'srmacklem2013-08-144-85/+230
| | | | | | | | | | | | | | | | | | | | | | | | | | | DRC for NFS over TCP. - Increase the size of the hash tables. - Create a separate mutex for each hash list of the TCP hash table. - Single thread the code that deletes stale cache entries. - Add a tunable called vfs.nfsd.tcphighwater, which can be increased to allow the cache to grow larger, avoiding the overhead of frequent scans to delete stale cache entries. (The default value will result in frequent scans to delete stale cache entries, analagous to what the pre-patched code does.) - Add a tunable called vfs.nfsd.cachetcp that can be used to disable DRC caching for NFS over TCP, since the old NFS server didn't DRC cache TCP. It also adjusts the size of nfsrc_floodlevel dynamically, so that it is always greater than vfs.nfsd.tcphighwater. For UDP the algorithm remains the same as the pre-patched code, but the tunable vfs.nfsd.udphighwater can be used to allow the cache to grow larger and reduce the overhead caused by frequent scans for stale entries. UDP also uses a larger hash table size than the pre-patched code.

Set this 10% above v_free_min so we wakeup before any phase transitions in vm users. - Adjust down v_free_target now that we're willing to accept more pagedaemon wakeups. This means we process fewer pages in one iteration as well, leading to shorter lock hold times and less overall disruption. - Eliminate vm_pageout_page_stats(). This was a minor variation on the PQ_ACTIVE segment of the normal pageout daemon. Instead we now process 1 / vm_pageout_update_period pages every second. This causes us to visit the whole active list every 60 seconds. Previously we would only maintain the active LRU when we were short on pages which would mean it could be woefully out of date.

| | | | | | | | | | | | | | | | | | | | | | Add definitions for e2fs_daddr_t, e4fs_daddr_t in addition to the already existing e2fs_lbn_t and adjust them for ext4. Other than making the code more readable these changes should fix problems related to big filesystems. Setting the proper types can be tricky so the process was helped by looking at UFS. In our implementation, logical block numbers can be negative and the code depends on it. In ext2, block numbers are unsigned so it is convenient to keep e2fs_daddr_t unsigned and use the complete 32 bits. In the case of e4fs_daddr_t, while the value should be unsigned, for ext4 we only need to support 48 bits so preserving an extra bit from the sign is not an issue. While here also drop the ext2_setblock() prototype that was never used. Discussed with: mckusick, bde MFC after: 3 weeks

Since the high bit can indicate either IEEE80211_RATE_BASIC or IEEE80211_RATE_MCS, it's up to the caller to determine whether the rate is 11n or not, and either mask out the BASIC bit, or call a different function. (Yes, this does mean that net80211 should grow 11n-aware rate2phytype() and rate2plcp() functions..)

| | | | | | | | | | | | | | | | | | | | | | | | extensions and also tried to be link time compatible with ports libiconv. This splits that functionality and enables the parts that shouldn't interfere with the port by default. WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc. WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker symbols and even a stub libiconv.so.3 that are good enough to be able to 'pkg delete -f libiconv' on a running system and reasonably expect it to work. I have tortured many machines over the last few days to try and reduce the possibilities of foot-shooting as much as I can. I've successfully recompiled to enable and disable the libiconv_compat modes, ports that use libiconv alongside system iconv etc. If you don't enable the WITH_LIBICONV_COMPAT switch, they don't share symbol space. This is an extension of behavior on other system. iconv(3) is a standard libc interface and libiconv port expects to be able to run alongside it on systems that have it. Bumped osreldate.

* FreeBSD's DTrace implementation has a few problems with respect to handlingmarkj2013-08-139-487/+362
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | probes declared in a kernel module when that module is unloaded. In particular, * Unloading a module with active SDT probes will cause a panic. [1] * A module's (FBT/SDT) probes aren't destroyed when the module is unloaded; trying to use them after the fact will generally cause a panic. This change fixes both problems by porting the DTrace module load/unload handlers from illumos and registering them with the corresponding EVENTHANDLER(9) handlers. This allows the DTrace framework to destroy all probes defined in a module when that module is unloaded, and to prevent a module unload from proceeding if some of its probes are active. The latter problem has already been fixed for FBT probes by checking lf->nenabled in kern_kldunload(), but moving the check into the DTrace framework generalizes it to all kernel providers and also fixes a race in the current implementation (since a probe may be activated between the check and the call to linker_file_unload()). Additionally, the SDT implementation has been reworked to define SDT providers/probes/argtypes in linker sets rather than using SYSINIT/SYSUNINIT to create and destroy SDT probes when a module is loaded or unloaded. This simplifies things quite a bit since it means that pretty much all of the SDT code can live in sdt.ko, and since it becomes easier to integrate SDT with the DTrace framework. Furthermore, this allows FreeBSD to be quite flexible in that SDT providers spanning multiple modules can be created on the fly when a module is loaded; at the moment it looks like illumos' SDT implementation requires all SDT probes to be statically defined in a single kernel table.
