* Renumber copyright clause 4Warner Losh2017-02-2811-11/+11
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Merge projects/ipsec into head/.Andrey V. Elsukov2017-02-061-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Small summary ------------- o Almost all IPsec releated code was moved into sys/netipsec. o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel option IPSEC_SUPPORT added. It enables support for loading and unloading of ipsec.ko and tcpmd5.ko kernel modules. o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type support was removed. Added TCP/UDP checksum handling for inbound packets that were decapsulated by transport mode SAs. setkey(8) modified to show run-time NAT-T configuration of SA. o New network pseudo interface if_ipsec(4) added. For now it is build as part of ipsec.ko module (or with IPSEC kernel). It implements IPsec virtual tunnels to create route-based VPNs. o The network stack now invokes IPsec functions using special methods. The only one header file <netipsec/ipsec_support.h> should be included to declare all the needed things to work with IPsec. o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed. Now these protocols are handled directly via IPsec methods. o TCP_SIGNATURE support was reworked to be more close to RFC. o PF_KEY SADB was reworked: - now all security associations stored in the single SPI namespace, and all SAs MUST have unique SPI. - several hash tables added to speed up lookups in SADB. - SADB now uses rmlock to protect access, and concurrent threads can do SA lookups in the same time. - many PF_KEY message handlers were reworked to reflect changes in SADB. - SADB_UPDATE message was extended to support new PF_KEY headers: SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They can be used by IKE daemon to change SA addresses. o ipsecrequest and secpolicy structures were cardinally changed to avoid locking protection for ipsecrequest. Now we support only limited number (4) of bundled SAs, but they are supported for both INET and INET6. o INPCB security policy cache was introduced. Each PCB now caches used security policies to avoid SP lookup for each packet. o For inbound security policies added the mode, when the kernel does check for full history of applied IPsec transforms. o References counting rules for security policies and security associations were changed. The proper SA locking added into xform code. o xform code was also changed. Now it is possible to unregister xforms. tdb_xxx structures were changed and renamed to reflect changes in SADB/SPDB, and changed rules for locking and refcounting.

* New sendfile(2) syscall. A joint effort of NGINX and Netflix from 2013 andGleb Smirnoff2016-01-081-3/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | up to now. The new sendfile is the code that Netflix uses to send their multiple tens of gigabits of data per second. The new implementation features asynchronous I/O, when I/O operations are launched, but not awaited to be complete. An explanation of why such behavior is beneficial compared to old one is going to be too long for a commit message, so we will skip it here. Additional features of new syscall are extra flags, which provide an application more control over data sent. The SF_NOCACHE flag tells kernel that data shouldn't be cached after it was sent. The SF_READAHEAD() macro allows to specify readahead size in pages. The new syscalls is a drop in replacement. No modifications are required to applications. One can take nginx binary for stable/10 and run it successfully on head. Although SF_NODISKIO lost its original sense, as now sendfile doesn't block, and now means something completely different (tm), using the new sendfile the old way is absolutely safe.

* Replace DPSRCS that work fine in SRCS.Bryan Drewery2015-11-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
