2020-12-19libc: implement getppid() reading /proc/$pid/ppid instead of /dev/ppidcinap_lenrek
The devcons driver is really the wrong place to serve per process information.
2020-12-19devsons: remove #c/pgrpidcinap_lenrek
The process group id is essentially a unique id of the namespace but it was never well documented nor is it used by any program.

2020-12-18vt: rfork environment varibles (thanks fshahriar)Ori Bernstein
vt sets several environment variables ($TERM, $COLS, $LINES) after exiting. This change rforks the environment so that this detritus doesn't get left behind.
2020-12-18strndup: don't assume buffer is terminatedOri Bernstein
Using strlen in strndup will walk past the first n bytes up to the terminator, which may not be present. This is not what we want. While we're here, do some cleanups.
2020-12-18kbmap: add Turkish keymap (thanks Kemal)kvik
2020-12-17hpost: support custom headers (thanks julienxx)Ori Bernstein
hget supports adding custom headers with -r; it makes sense for hpost to do the same, both because custom headers are more likely necessary with POSTs, and for consistency.
2020-12-17libap: add strndupOri Bernstein
strndup is part of POSIX.1, so APE should provide it. This patch adds it, so need to patch it out of fewer programs going forward.

2020-12-17ether2114x: vetting the driver for pc64cinap_lenrek
the tulip driver is used in microsofts hypver-v as the legacy ethernet adapter for pxe booting. to make the driver work on pc64, we need to store the Block* pointers in a separate array instead of stuffing them into buffer address 2 of the hardware descriptor. also, enable the driver in the pc64 kernel.

Bgeticon can fail, leaving the Icon img pointers nil.

2020-12-13oexportfs: move legacy code for cpu and import to separate programcinap_lenrek
The initial protocol handling in exportfs for cpu and import services is a huge mess. Saparate the code out into its own program with its own oexportfs(4) manpage.
2020-12-13kernel: implement per file descriptor OCEXEC flag, reject ORCLOSE when ↵cinap_lenrek
opening /fd, /srv and /shr The OCEXEC flag used to be maintained per channel, making it shared between all the file desciptors. This has a unexpected side effects with regard to channel passing drivers such as devdup (/fd), devsrv (/srv) and devshr (/shr). For example, opening a /srv file with OCEXEC makes it impossible to be remounted by exportfs as it internally does a exec() to mount and re-export it. There is no way to reset the flag. This change makes the OCEXEC flag per file descriptor, so a open with the OCEXEC flag only affects the fd group of the calling process, and not the channel itself. On rfork(RFFDG), the per file descriptor flags get copied. On dup(), the per file descriptor flags are reset. The second modification is that /fd, /srv and /shr should reject the ORCLOSE flag, as the files that are returned have already been opend.

2020-12-12sdiahci: enable pci busmaster before ahciconfigdrive() (fix qemu crash)cinap_lenrek
enable pci busmaster before set the fis-receive-enable bit in the port command register. not doing so triggers a crash in qemu like: address_space_unmap: Assertion `mr != NULL' failed. as qemu tries to process the dma command list as soon as we set that flag and busmaster dma needs to be enabled at this point.

2020-12-11pc, pc64: ignore MTRR's when MTRRCap.vcnt and MTRRCap.fix are zerocinap_lenrek
Bhyve returns 0 in MTRRCap register, so we can use that instead on relying on cpuid only to see if MTRR's are supported. That way we can get rid of the sanity check in memory.c.

2020-12-09backout OCEXEC changes when potentially opening /srv filescinap_lenrek
Opening a /srv file sets the close-on-exec flag on the shared channel breaking the exportfs openmount() hack. The devsrv tries to prevent posting a channel with the close-on-exec or remove-on-close flags. but nothing currently prevents this poisoning on open. Until this gets fixed in eigther exportfs or devsrv, i'll back out the changes that could have potential side effects like this.

2020-12-08pc64: preserve reserved bits in CR0/CR4 for amd64 in mtrr setstate()cinap_lenrek
On AMD64, CR0/CR4 are 64-bit registers, with the upper half reserved. So use uintptr type to store the register values to get 32 bit on 386 and 64 bit on AMD64.

2020-12-07vmx: add -v|-w flag to control window creation behaviourcinap_lenrek
The -v flag now does not create a new rio window, while -w flag does (restores the old behaviour). This allows vmx to run under vncs and is in general mode aligned to other emulators and programs.
