2016-01-05Some implementations of HitSyncDCache() call pmap_extract() for va->paVisa Hankala
conversion. Because pmap_extract() acquires the PTE mutex, a "locking against myself" panic is triggered if the cache routine gets called in a context where the mutex is already held. In the pmap, all calls to HitSyncDCache() are for a whole page. Add a new cache routine, HitSyncDCachePage(), which gets both the va and the pa of a page. This removes the need of the va->pa conversion. The new routine has the same signature as SyncDCachePage(), allowing reuse of the same routine for cache implementations that do not need differences between "Hit" and non-"Hit" routines. With the diff, POWER Indigo2 R8000 boots multiuser again. Tested on sgi GENERIC-IP27.MP and octeon GENERIC.MP, too. Diff from miod@, ok kettenis@

OK tb@ and he also pointed out that for consistency with rest of the tree we should include termios.h instead of sys/ttydefaults.h, where applicable
2016-01-04Record the modified mbuf chain after transmit checksum setup codeMike Belopuhov
Keep the modified chain pointer and pass it back to the calling code so that it will get properly accounted for. Change it to m_pullup since m_pulldown with a zero offset is just as good. Tested by yasuoka@, myself and mxb at alumni ! chalmers ! se, thanks! ok yasuoka, mpi
2016-01-04Bugfix: When errno happens to be EILSEQ upon entry to fgetws(3),Ingo Schwarze
and when the file ends without a terminating Ln character, fgetws(3) discarded any characters read and reported bogus EOF. Never inspect errno(2) unless right after an error occurred! OK millert@

2016-01-04Fix lots of bugs.Ingo Schwarze
1. When fprintf(fp, "...%ls...", ...) encounters an encoding error, do not destroy all the fp->_flags, which made the file permanently unreadable and unwriteable. 2. Do not change fp->_flags at all in case of encoding errors. Neither the manual nor POSIX ask for it, no other conversions set the error indicator, and it isn't needed because the return value reports failure and must be checked anyway. 3. Detect failure in mbrtowc(3), do not silently treat invalid bytes in the format string as the end of the format string. 4. Detect failure of __find_arguments(), no matter whether due to out of memory conditions or encoding errors, and gracefully fail rather than accessing an invalid pointer. 5. Remove the pointless and slightly dangerous errno = EILSEQ overrides after functions that already do that and are required by the standard to do so. OK jca@ on items 1, 2, and 5. OK millert@ on the complete diff. "Completely brutal mix of bugs." deraadt@

2016-01-04Improve handling of .Va and .Vt macros.Ingo Schwarze
tedu@ noticed that no Vt= database entries were generated. Serguey Parkhomovsky suggested the deletion of parse_mdoc_body(). tb@ noticed that the fix requires more than just adding TYPE_Vt to the MDOC_Vt mask in the mdoc_handler array.

2016-01-04Add initial support for 11n mode to the iwn(4) driver.Stefan Sperling
Only MCS 0 to 7 are supported for now. Tested by many. There might still be outstanding issues but they now appear to be rare. I'm putting this in so that additional fixes can be developed and tested more easily if required. This diff is already quite large for one commit. ok deraadt

2016-01-04Replace magic shifts and bitmasks used for ADDBA parametersStefan Sperling
with proper names, now that we have the corresponding macros.
2016-01-04Fix another case where the return value of ieee80211_chan2mode() wasStefan Sperling
used for indexing something other than ic_sup_rates. Should have been part of earlier commit.
2016-01-04ADDBA frames have a parameter set which we check against our own capabilitiesStefan Sperling
but we were checking bits in these parameters with the wrong set of bitmasks. Negotiating A-MPDUs with some APs failed because of this bug. ok kettenis@
2016-01-04Fix manual scan while associated in 11a mode. It would only show APs on 5GHz.Stefan Sperling
Problem found by benno@ ok benno@ kettenis@
2016-01-04Don't return 11n mode from ieee80211_chan2mode() so we can switch intoStefan Sperling
11a and 11b/g mode correctly when the driver supports 11n. And make sure the result of this funtion is only used to index ic_sup_rates. Its stated purpose is to help select a legacy rate. ok sthen jasper kettenis deraadt mpi

2016-01-04More headers removal and sorted the remaining alphabetically.mestre
Most noticeable that were removed are sys/types.h which will be included from stdlib.h and in turn also brings along sys/cdefs.h. The other one is limits.h that was used with the old idiom (denom * random() / LONG_MAX), although it was only removed were applicable (some files still need that header). OK tb@
2016-01-04Use err(3) instead of various handrolled combinations of perror(3) andtb
fprintf(stderr, ...) with strerror(3) and exit(3). Make sure the exit status is 2 if an error occurred. Prompted by gsoares@'s and jsg@'s audit of exit statuses after failure of pledge(2). ok gsoares@
2016-01-04pledge(2) spamd-setup(8)mestre
It needs these annotations, to at least run the operations next to them: stdio: malloc(3) rpath: open(2) inet: connect(2)/socket(2) proc: fork(2) exec: execvp(3) While here remove netinet/in.h since all we need is already in arpa/inet.h and sort the headers alphabetically OK beck@

2016-01-04Calling clone(2) with CLONE_NEWPID yields multiple processes with pid=1.Brent Cook
Work around this particular case by reseeding whenever pid=1, but as guenther@ notes, directly calling clone(2), and then forking to match another pid, provides other ways to bypass new process detection on Linux. Hopefully at some point Linux implements something like MAP_INHERIT_ZERO, and does not invent a corresponding mechanism to subvert it. Noted by Sebastian Krahmer and the opmsg team. See http://stealth.openwall.net/crypto/randup.c for a test program. ok beck@
2016-01-04Do proper termination of VMs by doing proper VCPU run state management.Mike Larkin
This should fix some of the odd termination errors people have been seeing (vmctl status showing running VMs after they have exited/crashed, and invalid instruction panics on vmptrld during certain races) This diff also implements dropping the biglock when running a VCPU, and reacquiring the lock as needed based on the type of exit (normal vs. external interrupt) diff supplied by Stefan Kempf <sn.kempf at t-online.de>, many thanks!

OpenBSD partition. Just one 128-byte stack copy of a single entry. Problems with EFI installs involving many disks reported by and fix tested by Thomas Bohl.

2016-01-03About 13 years ago when the idiom srandom(time()), and sometimesmestre
srandom(time()+getpid()), was changed by srandomdev(), but #include <time.h> lived up until this day so remove it. Additionally, earlier than that, 18 years ago, random(6) was one of the first consumers of arc4random(3) family, and was pulling it from dev/rndvar.h but these days we pull it from stdlib.h, which is already done, so while here remove dev/rndvar.h also.
