* Replace DPSRCS that work fine in SRCS.Bryan Drewery2015-11-255-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is so that 'make depend' is not a required build step in these files. DPSRCS is overall unneeded. DPSRCS already contains SRCS, so anything which can safely be in SRCS should be. DPSRCS is mostly just a way to generate files that should not be linked into the final PROG/LIB. For headers and grammars it is safe for them to be in SRCS since they will be excluded during linking and installation. The only remaining uses of DPSRCS are for generating .c or .o files that must be built before 'make depend' can run 'mkdep' on the SRCS c files list. A semi-proper example is in tests/sys/kern/acct/Makefile where a checked-in .c file has an #include on a generated .c file. The generated .c file should not be linked into the final PROG though since it is #include'd. The more proper way here is just to build/link it in though without DPSRCS. Another example is in sys/modules/linux/Makefile where a shell script runs to parse a DPSRCS .o file that should not be linked into the module. Beyond those, the need for DPSRCS is largely unneeded, redundant, and forces 'make depend' to be ran. Generally, these Makefiles should avoid the need for DPSRCS and define proper dependencies for their files as well. An example of an improper usage and why this matters is in usr.bin/netstat. nl_defs.h was only in DPSRCS and so was not generated during 'make all', but only during 'make depend'. The files including it lacked proper depenencies on it, which forced running 'make depend' to workaround that bug. The 'make depend' target should mostly be used for incremental build help, not to produce a working build. This specific example was broken in the meta build until r287905 since it does not run 'make depend'. The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS: SRCS:M*.h' when there is no .depend file.

* Define a LIB<NAME>DIR for every library that LIBADD provides.Bryan Drewery2015-11-252-0/+65
| | | | | | | | | | | | | | | This is going to be used to allow DIRDEPS to be bootstrapped off of LIBADD/DPADD. It currently works for internal libraries which have a DIR defined for them but also use the .a library from a src-mapped obj directory. It can also be useful for using -L without a --sysroot per LIBADD to use the OBJDIR version of the libraries. I didn't review every LIBADD, so it is possible this is missing some.

* META MODE: Avoid dirdep dependency on lib/libmd.Bryan Drewery2015-11-251-1/+2
| | | | | | | | | | | | | This avoids using the staged headers for sys/crypto/sha2/*.h, such as sha256.h, which added an unneeded pre-build dependency on libmd to libcrypt. This header is an INCS in lib/libmd, but found via .PATH in sys/crypto/sha2. Since the libcrypt build was already using the in-src libmd headers directly, just teach it how to find the sha256.h header as well.

* META MODE: Fix MACHINE=host builds.Bryan Drewery2015-11-251-8/+7
| | | | | | | | | | | | | | | | | | | We need to not use -nostdinc since it breaks building of clang itself. Use -isystem rather than -I/usr/include and -nostdinc which gets us using the stage include directory before searching the real host headers. This allows removing more of the -I hacks to get host headers since the headers are no longer excluded. The -B seemed unneeded. This fixes building of secure/lib/libcrypto which was looking at the /usr/include/openssl/asn1.h header rather than the staged one. This fixes building of clang which wants to find its own internal headers in the STAGEDIR/usr/lib/clang/* path. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=291324

* META MODE: Fix 'make bootstrap-tools'.Bryan Drewery2015-11-2512-43/+74
| | | | | | | | | | | | | | | | | | The main problem was bitrot after elftoolchain being swapped in for the GNU toolchain. This also reworks how the list of 'host allowed' libraries is determined to only allow INTERNALLIBs, which is needed for libelftc to come in. For usr.bin/readelf use the same hack, as libelf and libdward, to bring in the needed sys/ headers for host builds. This has not yet been a problem due to readelf not being built as a host tool in buildworld. This is possible in the meta build though when building the toolchain.

* Stop building vers.c in include/ and only build the needed osreldate.h.Bryan Drewery2015-11-253-8/+10
| | | | | | | | | | | | | | | | Because of how osreldate.h was being built with newvers.sh, which always spat out a vers.c dependent on SVN or git, the meta mode build was considering osreldate.h to depend on the current git or SVN index. This would lead to entire tree rebuilds when modifying git's index. There's no reason to be generating vers.c here so just skip it. While here, in mk-osreldate.sh rename PARAM_H to proper PARAMFILE (which newvers.sh already has a default for) and remove unneeded export.

* META MODE: Don't override DESTDIR to the default when building the toolchain.Bryan Drewery2015-11-251-1/+1
| | | | | | | | | | | | | | | For this case, the normal META MODE staging logic should be used. The BSARGS having DESTDIR= is due to Makefile.inc1 overriding DESTDIR to something when appropriate. For the toolchain stage META MODE is in charge of it, not Makefile.inc1. At least include/, if staging it to the host stagedir, was impacted from this. Staging of include.host is not yet done.

* [ath] listen to all beacons in IBSS and software beacon miss.Adrian Chadd2015-11-251-3/+7
| | | | | | | | | | | | | | | | | | | I added MYBEACON support a while ago to listen to beacons that are only for your configured BSSID. For AR9380 and later NICs this results in a lot less chip wakeups in station mode as it then only shows you beacons that are destined to you. However in IBSS mode you really do want to hear all beacons so you can do IBSS merges. Oops. So only use MYBEACON for STA + not-scanning, and just use BEACON for the other modes it used to use BEACON for. This doesn't completely fix IBSS merges though - there are still some conditions to chase down and fix. Notes: svn path=/head/; revision=291304

The race scenario: - Two threads (1 and 2) locate pcb with writer semantics (INPLOOKUP_WLOCKPCB) and do in_pcbref() on it. - 1 and 2 both drop the inp hash lock. - Another thread (3) grabs the inp hash lock. Then it runs in_pcbfree(), which wlocks the pcb. They must happen faster than 1 or 2 come INP_WLOCK()! - 1 and 2 congest in INP_WLOCK(). - 3 does in_pcbremlists(), drops hash lock, and runs in_pcbrele_wlocked(), which doesn't free the pcb due to two references on it. Then it unlocks the pcb. - 1 (or 2) gets wlock on the pcb, runs in_pcbrele_wlocked(), which doesn't report inp as freed, due to 2 (or 1) still helding extra reference on it. The thread tries to do smth with a disconnected pcb and crashes.

* ntb: Add MW tunable for MMR Xeon errata workaroundConrad Meyer2015-11-241-29/+57
| | | | | | | | | | | | | | | | | | | | | | | Adds a new tunable, ntb.hw.b2b_mw_idx, which specifies the offset (from the total number of memory windows) to use for register access on hardware with the SDOORBELL_LOCKUP errata. The default is -1, i.e., the last memory window. We map BARs before the b2b_mw_idx is selected, so map them all as memory windows initially. The register memory window should not be write-combined, so we explicitly disable WC on the selected MW later. This introduces a layer of abstraction between consumer memory window indices, which exclude any exclusive errata-workaround BARs, and internal memory window indices, which include such BARs. An internal routine, ntb_user_mw_to_idx(), converts the former to the latter. Public APIs have been updated to use this instead of assuming the exclusive workaround BAR is the last available MW.

| | | | | | | | | | | | | | | | | | | | Replace tlb_flush_local() by tlb_flush() as even not global mappings could be fetched to TLB(s) on other cores by speculative table walk. From OS point of view, it was not a problem as either such mappings were not used anymore or they were flushed from TLB(s) when reused. However, from hardware point of view, it was a problem. Not flushed mappings could be a target for speculative reads or prefetches (which might be quite aggresive on ARM cores). As speculative read can fill cacheline, it can cause a real problem, when physical page is reused, but mapped with different memory attributes. Anyhow, it's good to have only valid mappings in TLB(s). Approved by: kib (mentor) Notes: svn path=/head/; revision=291258
